No te the rock wall supp orting backfill of the old channel and th e riparian seed mix in bloom. Due to a rapidly expanding population in the Carolinas, especially in the Charlotte and Raleigh-Durham areas of North Carolina, large-scale transportation projects, residential and commercial development and subsequent urban stormwater runoff have taken their toll on many of the streams and wetlands . To help repair, restore and preserve these important aquatic resources , the North Carolina Legislature developed the innovative Ecosystem Enhancement Program (EEP). The EEP is part of the N .C . Department of Environment and Natural Resources, and uses a multi-agency approach to improve watershed functions through the advancement of planning documents and construction projects prior to impacts from development. Officially, the mission of the EEP is to "restore, enhance, preserve and protect the functions associated with wetlands, streams and riparian areas , including but not limited to those necessary for the restoration, maintenance and protection of water quality and riparian habitats throughout North Carolina ." Despite the EEP presence and its role as a valuable planning and funding source in North Carolina, the success of a large stream or wetland restoration project, especially in an urban area , often depends on having a good loca l sponsor. The role of the local sponsor varies from project to project, but it can include coordination between municipal departments , public outreach , agency coordination, monetary support and technical review. Having good local support from a municipal engineering, planning or stormwater department can make or break a project. Littl e Su gar Creek Initiative In the past three years , an enterprise has been underway in the Charlotte region , specifica lly in Mecklenburg County, to create greenways, enhance connectivity and mobility and improve the environment One significant project championed locally is the Little Sugar Creek Environmental Restoration Initiative, which encompasses stream restoration, greenway trail development and overall enhancement of the stream corridor. It covers a 15-mile section of Little Sugar Creek running south from Uptown Charlotte to the North Carolina/South Carolina state line. continued on page 2 - Freedom Park... continued from page I Phase 2 of this initiative is a joint effort between Mecklenburg County and the EEP known as the Freedom Park Stream Restoration Project. The EEP-funded project is one of the largest of its kind in the state, placing more than 1,500 linear feet of stream on a new alignment as much as 150 feet from its current location. The Little Sugar Creek flows through the entire length of Freedom Park, a distance of more than 4,500 linear feet. Freedom Park is in a highly urbanized setting two miles south of the central business district. The 14- square-mile watershed is virtually built-out, with the only development occurring on in-fill locations . Therefore, urban runoff and stormwater are the main contributors to stream degradation along this section of the creek. Historical records indicate that Little Sugar Creek likely was channeled and straightened in the early 1900s to improve stormwater conveyance and allow urban development to occur on the floodplain. In the 1970s and '80s, the creek was showing signs of instability due to upstream development, so a concrete and grouted rip-rap liner was installed along the banks to provide stability and prevent erosion. The stream remained in this state for the next 25 to 30 years . In 2002, Mecklenburg ColU1ty awarded a contract to demolish the concrete banks in preparation for the upcoming restoration project The demolition ran concurrently with the design and permitting of the channel restoration. Po s t-co ns tru ction up s tream vi ew of th e regraded s lop es and enhanced habitat of th e Freedom Park s tretch of little Su gar Creek. Freedom Park Restoration Details HDR, and a local environmental specialty firm , Habitat Assessment and Restoration Program Inc., were selected for this project based on past experience in the watershed, availability to devote technical expertise and other resources to this complex project and a familiarity that had been formed through previous work with EEP. The team performed an extensive watershed survey, a sediment transport study, a reference reach analysis and a site survey to achieve a permittable and stable design. The final design incorporated natural channel techniques to enhance and create habitat, provide stability, improve water quality, control stormwater rlll1off and provide a more aestheticaIIy pleasing stream ecosystem. Constrnction began in March 2003 and was completed in September 2003 , despite having one of the wettest summers on record in the Charlotte region. In fact , Charlotte had obtained its average annual rainfall allowance by August 1. Even with the muddy conditions and frequent flood events, the stream remained stable throughout the construction process . The constructed stream has 15-foot bank heights and 30-foot bottom widths and was built economically, though it required moving more than 50,000 cubic yards of earth, placing over 3 ,000 tons of boulders, river cobble and rock cross vanes and planting 40,000-plus trees and shrubs . Considering the large quantities of materials moved and used on this project, remarkably all of the excavated material was disposed of on-site . This reduced costs and provided additional floodplain area for flood storage and riparian habitat. The stream was narrowed for the majority of the project length to help push sediment through the system and prevent sand and silt from blocking the normal stream flow and reducing aquatic habitat. Due to the "flashy" nature of this stream during rain events, this project was being constructed "in the wet" without the use of pumps to move the water around the active construction zone. Instead, rock check dams were placed at the end of the project and immediately below construction zones to trap sediment. Pre-construction photo of stream reach shown above.

Of special interest was the implementation of constmcted riffies, which provide stability and habitat using a combination of stone and boulder materials. As part of the restoration , more than 20 shmb and tree species were planted to further stabilize the banks and reforest the upland areas. Additionally, a diverse seed mix was used to provide herbaceous cover along the banks . An important component of this project was the involvement of the community during the planning and constmction phases. Public meetings for input and review were held throughout the course of the project to facilitate the sharing of information with the community and several special interest groups. Prior to and during constmction , signs indicating schedule and project team members were posted. Images of the final conceptual design and descriptions of the rationale behind the design elements were posted in kiosks along the stream .

Summ ary This is the first in a series of four Little Sugar Creek projects currently undergoing restoration and greenway trail development. The four segments are part of the much larger watershed-wide environmental initiative that includes demolition of concrete liners , dam removal and "daylighting" (removing parking decks from above the stream). The Freedom Park Restoration project and the EEP funded portions of the larger Little Sugar Creek Environmental Restoration Initiative stand as examp les of how the EEP plans to carry out its mission by providing: • High-quality, cost-effective projects for watershed improvement and protection • Compensation for unavoidable environmental impacts associated with transportation infrastmcture and economic development • Detailed watershed planning and project implementation efforts within North Carolina 's threatened or degraded watersheds Aerial view of th e new upp er meanders taken shortly after construction. As outlined in the EEP 2003 Annual Report, "during this past fiscal year, efforts have resulted in a total of 37 stream and wetland restoration projects that are either completed or in constmction, totaling 127,632 linear feet of streams and 466 .9 acres of wetlands . An additional 35 projects are in the design phase and upon completion will result in the restoration of 91 ,480 linear feet of streams and 478.5 acres of wetlands. In addition, policies have been developed and implemented for improved riparian plantings as well as vegetation monitoring techniques." Chris Matth ews can be reached at HDR s Charlotte, N.

Anny Corps of Engineers (USACE) made a quantum leap forward in the way it conducts its executive-level monthly board meetings by using Web-based technology to display live schedule and budget data. A meeting that often lasted nine to 10 hours was three hours shorter using the new tool , and preparation time for the presenters was reduced by one to two days . The organization projects a savings of $450,000 annually due to reduced labor and reproduction costs . The tool that made all of this possible is CorpsConnect, a Web-based program management system. CorpsConnect uses the latest in thin client technology (which places an application on a server, allowing access to multiple users) to sort, query and display data from multiple sources associated with the Jacksonville District's operation in an easy to use Web browser environment. CorpsConnect uses queries based in Structured Query Language (SQL) to ask questions of multiple databases, then displays the answers in a single environment. CorpsConnect was created to support the implementation of an integrated program management philosophy that focuses on improving operational execution of projects at the local level. Another key factor in its development was the increased demand for data spawned by adding the Comprehensive Everglades Restoration Plan to the Jacksonville District's list of duties. This new responsibility created unprecedented staffing growth and the pressure to create a more efficient organization. Development Proces s CorpsConnect was developed in a partnership among the Programs and Project Management and Information Management divisions of the Jacksonville District and HDR It is not simply an "off-the-shelf' product, but rather the result of a well-planned approach that included interviewing a cross section of the Jacksonville District staff. Participants were asked what types of information ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--, Financial .... Scheduling Construction Management r c:::l ("o rp.\ .... C @ 0 • N • N • E • C • T ...

Information from those interviews, along with snapshots of actua l Jacksonvi lle District project and program data (e.g., schedule, financial and GIS), was used to construct an initial prototype of CorpsConnect. The prototype was previewed to key Jacksonville District personnel in a series of workshops to obtain feedback and further refine the application. In the second phase of the project, programmers connected the prototype to live Jacksonville District project information . After testing, the CorpsConnect team s lowly expanded the user community and further enhanced CorpsConnect in a spiral development process . In January 2004, CorpsConnect was presented to the Jacksonville District 's Project Review Board (PRB) for consideration . The district commander for the Jacksonville District was so pleased with CorpsConnect that he directed the development team to create a module that would allow the February PRB meeting to be run in a paperless environment. The team accepted this challenging task and, despite a tight schedule, delivered the PRB on CorpsConnect module to the district commander in 20 days. PRB on CorpsConnect has served as a catalyst to he lp the Jacksonville District's PRB better focus on the obstacles of operational execution by providing real -time live schedule and budget data in a consistent format. This new way of looking at information allows problem areas of projects to be more easily recognized, providing enhanced decision support by the Jacksonville District 's PRB. However, PRB on CorpsConnect is just one of five modules that will make up the entire CorpsConnect tool. The remaining modules are: • An internal customer portal • A public data portal • A GIS portal • A wireless portal The internal customer portal and PRB on CorpsConnect are the most complete modules at this time . The navigation buttons currently available on the site are Projects, Programs, Sponsors, GIS , PDT and Reports. These modules are a direct reflection of the information that was obtained during the interviews and needs assessment phases of the project CorpsConnect's other capabilities include transforming query information into Microsoft Excel or Word format to allow external processing of the data without affecting the integrity of the data source. Additionally, all of the data views in CorpsConnect can be sorted by any column header. CorpsConnect also has the flexibility to allow new columns of data to be shown or new data views to be created with minor programming that does not disrupt online access. This allows the tool to be easily adapted to the Jacksonville District's changing needs. Future plans for CorpsConnect include : •Enhance the GIS module with aerial photograph layers and the ability to display project locations based on criteria such as funding sources, sponsors, etc. • Deliver portions of CorpsConnect to wireless devices such as a Blackberry • Connect to additional Jacksonville District databases such as the ORM regulatory database and the RMS construction database • Connect to P2, an integrated financial and schedule database that is being deployed throughout the USACE Another key benefit of CorpsConnect is the empowerment it creates by providing all levels of the Jacksonville District access to the same information at the same time . This effectively links the entire organization , from top to bottom. In doing so, CorpsConnect lays the groundwork for enhanced customer confidence by facilitating better responses to sponsor and stakeholder questions . Schedule data quality and completeness also were improved by giving more Jacksonville District personnel the opportunity to see schedule data and work collectively to improve it. Beyond providing better access , CorpsConnect contains custom queries that allow the users to quickly determine projects that are missing important milestones or have the milestones coded incorrectly. Several circumstances have contributed to CorpsConnect's success . One key factor was a shift in business thinking within the Jacksonville District. This was exemplified by the creation of a new Program Controls Branch, which focused on an integrated program management philosophy. Combined with its move to a new office, the Jacksonville District has established a clear opportunity for its staff to make a fresh start. Finally, the adaptability of the project team had a significant effect on the outcome . Entering the project, the one surety was that the team would need to evolve as work progressed . In the end, it was the gathering of a diverse body of individuals -ranging from Web developers to forestry and geology experts -into a single, cohesive unit that provided the necessary resources to complete the CorpsConnect project. Summary Knowledge management solutions such as CorpsConnect have broad reaching applications for many private and government entities. In today's digital age, it is not a lack of data but an A Closer Look ------·· . Figure 1 inability to sort and use the data in a meaningful way that hurts overall organizational effectiveness . Tools such as CorpsConnect provide a mechani sm to link vast data from divergent sources and transform it into usable knowledge . In this case, it also provided immediate cost savings of $450,000 annually with just the first of five planned modules. However, the magic of CorpsConnect is not software or technology, but rather the implementation of sound management consulting principles that promote development of systems that will enhance overall organizational effectiveness. In the end, the process the Jacksonville District used allowed it to determine what types of data were important and how they should be viewed -and from there it was able to identify the best possible solution. With the implementation of CorpsConnect, the Jacksonville District has taken an important step toward a totally integrated program management philosophy and practice . With this approach, the Jacksonville District moves closer to the goals of the USACE's 2012 Plan of continued success in the future. Mark A.

Residents of Grand Forks, N .D., and East Grand Forks , Minn., will not soon forget April 1997 -a month that brought the worst flooding in the area's recorded history. With a population of about 60 ,000 , the sister cities are located 90 miles south of the United States-Canada border along the banks of Red River of the North. The Grand Forks area has endured at least seven floods in the past 200 years. The surge of water created by snowmelt in the spring is compounded by the river's northward course . As the water reaches colder temperatures , the river becomes prone to ice jams. During the winter of 1996-1997, eight blizzards hit the Red River Valley. The Grand Forks /Ea st Grand Forks area received more than 98 inches of snow -more than double the 41-inch average annual snowfall. The final blizzard came in early April 1997 , adding another 6 inches of snow to the already overwhelming amount of water being absorbed by the Red River. It proved to be just one more ingredient in an already brewing disaster. In anticipation of the impending flood, residents stacked sandbags and clay along the river's shores . But as temperatures climbed, the river seemed to rise even faster. On April 18 , the Red River spilled over the makeshift dikes , flooding both Grand Forks and East Grand Forks. The water level rose for three days -sometimes at a pace of an inch an hour -before cresting at 54.3 feet (more than 26 feet above the flood stage) on April 21 . CNN quoted one witness as saying the river behaved like "a steadily climbing animal." The 500-year flood spread muddy water over more than half of Grand Forks and almost all of East Grand Forks. Nearly every resident of the two cities was forced to leave their home, and most returned to find their property damaged. In On e of three stepped hy draulic drop s tru ctures which co nvey water from the En g lish Coulee Divers ion approximately 30 feel down to th e Red River of th e North. In set: example of previous drop s tructu res . downtown Grand Forks , flooding triggered an electrical malfunction in an historic building. With firefighters hampered by the flood , the fire spread to l l buildings. In response to the flood , the U .S. Army Corps of Engineers (USACE) district office in St. Paul , Minn ., worked with both communities to formulate a plan to mitigate the area 's flood risk. Their stated goal was to "develop a permanent, comprehensive flood damage reduction project incorporating recreation and aesthetic features ." A General Re-evaluation Report and an Environmental Impact Statement were completed in 1999. Numerous design options were considered, ranging from taking no action at all to a complete diversion of the Red River around Grand Forks. The preferred alternative USACE identified included a mu lti-phase approach to widening the floodway and constructing new levees . English Coulee Diversion Phase 1 of the levee construction program began in summer 200 I and has since been completed . HDR was called in by USACE to assist with Phase 2 of the Red River flood control project, the English Coulee Diversion . Phase 2 included excavation of more than 1.1 million cubic yards of material in order to construct 4 miles of new channe l and widen 3.5 miles of existing channel. The project team developed a hydraulic model of the proposed diversion route using HEC-RAS to evaluate various channel a lignments and alternatives. The team also sized hydraulic structures and prepared two design documentation reports to track work progression . Civil design for the English Coulee Diversion included planning utility relocations , evaluating which residences and businesses would need to be relocated , raising major interstate freeways and redesigning Interstate 29 and U .S. Highway 81 . Geotechnical design covered the evaluation of slope stability and the behavior of a lkali soils. Structural design of deep pile foundations included considera- tion of both soi l and hydraulic loading . Design Challenges One of the most significant obstacles in the design of the English Coulee Diversion was the existence of very soft and highly plastic clays in the soil. Such unstable soil typica ll y makes for poor levee material because it is difficult to handle and weakens when - Building a Team of Experts Engineers from multiple offices ond subcontractors colloborated on the English Coulee Diversion, allowing each to focus on his or her area of expertise. The result wos o com- plex ond comprehensive design pockage that included the following services : • Prelim inary & Final Design • Alternative Assessments • Contract Drawings & Specifications • Hydraulic Design • Quantity Take -Offs • Interior Rood Control • Design of Gates & Hoists • Foundation Design • Computer-aided Design & Drafting • Steel & Concrete Design • Geotechnical Design • Utility Coordination • M-CACES Cost Estimating • Structural Design • Local Flood Protection • Mechanical Design compacted . The designers accounted for these unique , but les s than favorable soil conditions by developing a massive embankment section with flat side s lo pes and large crest widt h. The task of managing a project with such a broad spectrum of stakeholders and technical discip lines proved to be a formidable challenge in its own right. The primary goal was providing flood protection to the communities of Grand Forks and East Grand Forks. But the project team also had to satisfy requirements set forth by the North Dakota Department of Transportation , USACE and the Grand Forks County Highways Department. In the end , the design included considerations for hydraulic , geotechnical, roadway, traffi c, structural and safety issue s. Typical channel crossing along th e English Co ulee Diversion. Each stmcture uses fo ur 15-foot x I 0-foot pre-cast reinforced concrete box culverts. Diversion we ir directs high flows to the Eng lis h Coulee Diversion. Lower flows travel to a coulee system to maintain a natural channel ecosystem. Conclusion Today, as co nstruction of the Eng lish Coulee Diversion nears comp letion and the next phase in the levee expansion plan gets underway, the people of Grand Forks and East Grand Forks are nearing the day when they no longer have to live in fear of the next great flood. At a total estimated cost of more than $405 million , that peace of mind may appear to carry a heavy price . But when compared wi th the estimated $1 billion to $1.5 billion in losse s incurred in the most recent disa ster alone , it could be argued that the Red River flood protection program is as cos t-effecti ve as it is reassuring .

Red overlay indicates areas where th e p roposed tank would be vis ible. Pho tos below demons tra te how true 3-D models allow analysis fro m any p ersp ecti ve. • Coosensus building Whether it 's a critical public hearing to discuss the aesthetic impact of a large reservoir or a topographic look at a residential development site, visual simulation provides a flexible and potentially comprehensive set of tools for analyzing a broad range of engineering projects . For example, the San Vicente Pipeline project in San Diego County, Calif., involved placement of a series of access shafts adjacent to an approved housing development for the purpose of completing underground construction . Existing topography, grading elevations from the residential development plan and the shaft designs were used to create multiple 3-D elevation models . The process involved seaming the three components into a single , complete topography ; converting that topography into a 3-D Triangular Irregular Network (TIN); draping an aerial photograph and polygons for the major grading scars onto the TIN ; and , finally, adding structures such as houses, the road and bridge design and the shaft structure . The client used the final images to choose the most viable alternative for this high-profile site . Visual Simulation Use and Methodology Project presentation can be a difference maker when it comes to stakeholder buy-in and establishing community consensus. For this reason , using visual simulation to create a model offers a powerful mechanism for communicating specific project objectives to an audience. In cases such as the San Vicente Pipeline, where public perception was of vital concern, visual simulations also can be a valuable tool for conveying complex technical concepts in a manner that allows the layperson to understand the parameters of a project. Utilizing true 3-D modeling that is based on geo-referenced data , virtually any view or direction can be achieved with minimal difference in time or cost. This provides the added benefit of facilitating the integration of design changes throughout the course of a project. The mo st basic form of GIS-based 3-D simulation is digital terrain modeling . Using data from a variety of sources, including Digital Elevation Models from U.S. Geological Survey and survey-derived CAD topography, analysts are able to create a bare-earth surface image of the project terrain. By then draping an orthorectified aerial photograph or satellite image over the model , it makes visual referencing of individual project components dramatically easier for the non-technical eye . An additional layer of sophistication comes from including structures , vegetation and other project components -resulting in an enhanced, realistic view that permits thorough analysis of potential view-shed impacts. Practical Applicatio ns In a recent presentation to the Otay Water District in southern San Diego County, HDR provided visual simulations of proposed water reservoirs , in part to address concerns about line of sight issues. A simulation was created from the perspective of a nearby re sidence, and view-shed impact maps were used to define surrounding regions - that might have a clear line of sigh t to the proposed 2-million-gallon water tanks. With the visual simulation technology available today, analysts were able to produce these models in less than two days . One private sector industry that has embraced visual simulation and the correlating assessment tools is residential development, which uses project models for a variety of applications. A clear example would be fulfilling visual impact assessment requirements of environmental laws such as the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). Triangulated Irregular Network of proposed grading, with fi1ture bridge and planned sing le-family residen ces before "seam ing " th e model into project photos for more reali stic simulations. Developers also are turning to GIS for 3-D analysis that stretches beyond modeling for visual impacts . The Saddleback Meadows development in Orange County, Calif., for example, took a model that originally was developed for visual purposes and used the information to analyze slope conditions . When compared with compatibility guidelines from the county, the data became a decision support tool that impacted the overall design of the project. In some instances , visual simulation plays a key role in determining what action should be taken. The Canyon Lake Sedimentation Study and Improvement Project, conducted for the Lake Elsinore and San Jacinto Watershed Authority, is such a project. Using data collected by field biologists , analysts generated 3-D models of the lakebed surface and sediment surface of this several-hundred-acre body of water. The models enabled a detailed assessment of sediment level s and accumulation, which was used as the primary decision support tool in determining whether dredging and sediment removal was necessary. Conclusion Beyond environmental sciences and resource management, the potential applications for visual simulation are as vast as the breadth of projects that engineers delve into on a daily basis .

The Bay's rivers and streams are its arteries and se rv e as nursery gro und s for impor- tant co mmer cial fishe ry stock, s uch as ee ls or blu e crabs. Increasingly, it is rec- ognized th at the rivers and streams that feed the Bay mu st a lso be clean and healthy, if the Bay is to regain much of its fo rmer life and productivity. 'Chesapeake 2000' Bay Agreement The C h esap eake Bay Program, fo rmed in 1983 by the first C hesapeake Bay Agreement , is a unique regional partner- ship leading and directing the restora - tion of the C hesapeake Bay. The Bay Program partners incl u d e the states of Maryland, Pennsylvania and Vi rginia; the District of Columbi a; the Chesapeake Bay Commi ssion, a tri-state legislative body; the U.S. E nviro nmental Protection Agency (EPA), wh ic h r epre - sents the fed eral gove rnm ent; and par- ticipating citizen advisory groups. For n ea rl y twenty years the Bay Program partners have so u ght to protect and restore this unparall e led resource. The second Chesapea k e Bay Agreement, adopted in 198 7, esta bl is h ed a visio n for the Bay's restoration. Its goals incl ud ed proposed reductions of h armful nutri- ents . In 1992, the Bay Program m oved upstream , with strategies for attacking nutrients at their so urces in the Bay 's tributaries. The C hesapeake Exec utive Counci l (CEC)-co mposed of the Governors of Maryland, Pennsylvania and Virginia; the Mayor of Washington , D .C.; the EPA Admi ni str ator; a nd the Chair of th e Chesapeake Bay Commi ssion -sig n ed fi ve directives in 1993 that add ressed ke y areas to be restored. These areas included the trib - u taries, toxi cs, unde rwate r Bay grasses, fish passages and ag ri cul t ural nonpoint so urce pol lution. In 1994, the partn ers o utl ined initiatives to restore aquatic , riparian and upl and habitats , reduce nutrients in th e Bay's tributaries and r edu ce toxics , emphasizing the preven - tion of pollu tion . Throughout the 199 0s, the Bay Progr am developed programs to engag e local gov- e rnments in the Bay restoration effort, es tablished priorities for land, growth and stewardship throu ghout the Bay region, set goals to increase riparian for - est buffer s, ren ewe d commitments to red uce nutrients in the Bay, ex panded wetlands protection and broadened its support for community-based wa tershed res toration efforts . On June 28, 2000, the CEC sig ned C hesapeake 2000 -a co mprehensive and far-reach in g Bay Agreement that will guide the Bay Program p artners through the year 2010 in their combined efforts to co ntinu e to res tore and protect the C h esapeake Bay. Chesapeake 2000 out- lines ninety -three co mmitm ents, d etail - ing protec tion and r es toration goals criti - cal to the h ea lth of the Bay wate rsh ed . It pledges to in crease riparian forest buffer s, preserve addi ti onal tracts of land , restore oyster populations a nd pro - t ec t wetlands . Chesa peake 2000 foc u ses on improving water quality as the most critical element in the overall protection and r estorat ion of the Bay and its tribu - taries. In recognition of the importance of th ese arteries, C hesapeake 2000' Bay Agreement includes a number of goa ls related to Bay trib utari es, su ch as: "By 2002, ens ure that measures are in place to meet our rip arian for est buffer restoration goa l of 2,0 10 mil es by 2010 ." The agreement also calls for local water- shed m anage m ent plan s to b e dev ised and implemented by 2010 in two-thirds of the Bay 's watershed. Goals for the reduction of nutri en t loadings, standards fo r aquatic liJe and other criteria ar e also found in the n ew Bay Agree m ent.

Vi Introduction Strean1s serve as the circu latory sys- tem for our land . The system (the hydro - lo gic cy cl e) m oves water thro ugh the envi- rorunent as surface water, gro und water and vapor, and also stores it in vegetation. Once water fa lls from the sky as rain onto the land, it drain s from that land into a particular riv er or body of water. That land area is known as a waters h ed. Taking care of our streams req uires taki n g care of a watershed's land , sin ce land runoff is a principal source of stream pollution. For instance , th e U.S. Environmental Protection Agency (EPA) estimates that more than half of all stream poll uti on co m es from land runoff, which can con- tain pollutants such as sediment, oil, fecal material, fertiliz ers and pesticides. Stream corridors provide vital n etwork s fo r wil dlife and, in many urban areas, streams are thei r la st remaini ng habitat. Streams surrounded by a healthy mix of native vegetati on incl udin g grasses, shrubs and trees can b e buffer ed from the effects of s urrounding land us es, which might otherwise h arm the stream . This chapte r pro vi des an overview of why it is important to protect streams and the valu es and fun ction s that they provide. Under standing strean1 valu es (s uch as flood co ntrol ) and ensurin g that their functions (s uch as water storage and transport) are not hindered are criti cal to achievi ng a successful stream protec tion strategy. w~terslied: An area of land that drains into a particular river or body of water. The watershed includes its associated groundwater. High land forms serve as watershed divides. Several watersheds together form a drainage basin. I I I The Benefits of L ocal Stream Protection Stream Functions and Values Streams a nd floodplains are not onl y land scap e features they also perform important fun cti ons , s u ch as the s torage and tran sportation of la nd runoff. U nde rstandin g how streams function is criti cal to the adoption of feasib le strate- gies fo r th ei r management. All too o ft e n , planne rs and elec t ed offi- cia ls onl y con sider the n eed to more effective ly manage str eam chan n els after a fl ood event, when they mu st deal with the costs associated with emerge n cy repai r s and th e loss of p roperty and li ves. They fail to reali ze that the ca u ses of increased flooding a n d str eam damage ar e often the resu lt o f changes to the watersh ed 's land deve lopment patte rns, which may have m odifi ed th e hy drologic reg ime so that storm fl ows peak higher and faster than befo re, ca u sing greater in -s tream bank erosion, stream bed sco uri ng and habitat d amage. Streams normall y chan ge th eir co urse over time, so m eti me s dramati ca ll y, du e to natural causes su ch as hurri canes or avalan ches. H owever , dram atic changes can a lso b e wrought by the s udd en p aving of portions of the wate rshed. Increasing th e amount of pav ement in a watershed, or eve n chan gi n g la nd use from forests to fields, can greatly in cr ease di sc harge to stream s, since both of these greatly reduce land p e rmea bili ty and soi l storage . Eventua ll y, a stream will adjust t o a n ew eq uil ibrium, but thi s may take many yea rs, or eve n d ecades , to achieve. A stream 's channel , se dime nt load and phys ical patterns, suc h as it s si nuosity (c urviness), mu st r e-adj ust t o flows that are higher and / or sudden ly carrying increased se diment and debris . A stream wi ll work to gain a new equi - lib rium to match alte red rates o f runoff from the land . The notion that streams perform physi- cal functions ca n be understood by thi nking about th e va ll eys ca u se d b y the process of erosion, whereby streams carry away the sedi m ent and organic matter was h ed fro m m o untain s and se rve to carve pathways through our land - scap e, changi n g in response to floods, geo logic uplift , h uman a lterations, cli - matic changes and other factors. Events such as floods also se rve an important function in deposition of ri ch soi ls within the fl oodplai n that nouri sh the floo d - p lain's vegetation , whi ch in turn n ourish- es wildlife . U nderstanding how streams fun ction is key to devising a su ccess ful approach to protec ting them. For ex am - p le, an approach that does not facto r in the n atural t endency of the stream to flood may result in loss of prope rty a nd even lives. In urban watersheds , people A Stream Corridor P ro tec tion Strategy for Local Governments 1 may not have left roo m for a stream to change its pattern becau se the floodp lain has already been deve loped . The Need for a Stream Co rridor Protection Strategy There are many reaso n s a lo ca lity may decide to deve lop a st rat egy to protect a particular str eam or t h e tributaries of an entire wa t ershed. Regu latory drivers, such as t he new Total Maximum Daily Load (TMDL) and Stormwater provi - sions of the federal Clean Water Act, or the need to provide clean water supplies under provisions of the federal Safe Drinking Water Act may heighten the n eed to protect surface waters. Alternative ly, the need t o conform with state provisions, such as Virginia 's Chesapeake Bay Preservation Act or Marylan d's Critical Area Act may require local governments to engage in watershed protection. Cle an Water Act Government agencies at the federa l , regional , st ate and local level have bee n taking a greater interest in preventi n g t h e impact of excess storm water, as new requirem en ts for contro ll ing sto r mwater come in to p lay. The fe d eral Clean Water Act (C WA) requires that cities and urbanized co u nties with populations greater than 100 ,000 p eople deve lop stormwat er managemen t plans and obtain d ischar ge permits for stormwater outfall s. As a result , municipalities wh ich fa ll un d er these req uirem en ts are havi n g to implem en t new co ntro ls for storm wa- ter ru n off and can no lon ge r simply al low runoff to fl ow directly in to streams thou gh stormwater disc h arge pipes. Other new regulatory requirements that are now taking effect in cl u de the Total Maximum Daily Load (TMDL) Progr am un der the fe d eral CWA, which requires th at states set p o ll ution co ntrol pl ans fo r impaired rive rs and stream s. (For more on TMDLs and other reg ul a- t ions , see Appendix C). These new programs may cost states and m u nicipali ties millions of dollars to tack - le. Plannin g n ow allows local and state agencies to take a phased approach to addressin g stream probl ems and wi ll not onl y save mon ey over the long term , b u t wi ll also a ll ow more c reative and effec- tive solutions to these problems. Examples of how potential solutions can be applied are found throughout this guide. Regional and Multi-State Restoration/Protection Goals There are also regional and multi-state requireme nts that drive watershed pro - tection effo rts . With a 64,000 square mile drainage basin e ncompassi ng Maryland, Pennsy lva n ia , Virginia, the District of Columbia and parts of New York and West Virginia, the health of the Chesapeake is directly dependent u pon the quality of the streams that feed it. Bay drainage map The Chesapeake 2000 Bay Agreeme n t signed by the Governors of Maryland , Vi rgi n ia, Pennsylvania and the Mayor of the District of Columbia's establis h es volu n tary goals for stream protectio n across the basin . Fo r example, it ca ll s fo r each jurisdiction to develop guidelin es by 20 01 fo r t h e aquatic health of streams and to develop stream co r ridor resto ra - tion goals based on loca l watershed man - agement planning by 2004 . This g u id e can assist plann e rs, watershed managers and elected officials effectively imple- ment such p lanning. 2 C hapter O ne: The B enefi ts of Local S tr ea m P ro tection Local Val ues of Stream Protection Apart from regulatory drivers , a locality also may decide to improve stream pro- tection measures to enhance or protect eco nomic values. One ex ample of this wou ld be if a town wants to promote tourism using a riverwa lk promenade that depends on a clean and healthy waterway. Nature-based tourism, or 'ecotourism,' is another economic ration - ale that can lead to efforts to protect streams . For example, Virginia 's Nelson County is a largel y rura l, mountainous co unty that is continually seeking to pro - mote its 'natural heritage ' as a way to bring n ee ded tourism dollars to the cou nty. A key aspect of promoting he r - itage tourism in Nelson Cou nty is pro- tectin g the health of the Rockfish River for u ses such as fly fishing and canoeing. Community values may serve to form the pri nci pal driving force for stream protection. For example, a community- level initiative led to the creation of Minimum In-Stream Flow (MIF) stan - dard s for Virgi n ia's Mau ry River in the mid 1990s, Citizens wa n ted to ensure that fishing, boating and eco logical health wou ld not be harmed by low flows resulting from excessive water withdrawals. Pressures of development While the C lean Water Act (CWA) has done much to protect strean1s and r ivers from the runoff of large ind u strial and m un icipal dischargers, the rapid pace of development in the Bay's watershed s h as res ul ted in more paved s urfaces . T hese have caused higher runoff, which ca rries contaminants that are harmful to s u rface and ground water . It is estimated that the population east of Interstate 9 S will continue to grow rapid ly on the lands closest to the Chesapeake Bay. This pop - ulation boom will make the goal of pro- tecting and restoring the Chesapeake all the more diffic ul t . Protecting streams and rivers from t h e impact of population growth will not only help to protect the Bay, but also the quality of life for loca l residents, busi- nesses and stream-dependent fish an d wild life. A s growth occurs, the demand for drinking water supplies increases. Streams that may not have been co n sid- ered a priority are suddenly eyed as th e key to n ew d eve lopment . Also , as com- munities grow, groundwater so urces may dissipate as limited aquifers are tapped by more we ll s. A s our under - standing about contamin a nts has expanded , so have t h e standards required to prevent the co ntamination of public drinking water supplies. Community strategies Communiti es should look to implement- ing protection strat egies n ow, in o rd er to e n sure th e safety of futur e drinking water supplies, fifty perce nt of which co me from surface wa t er. In the long run , it is much less ex pen sive to e nsure that today's land uses do not harm the futur e of the strea m as a source of drink - ing than it is to try to restore the quality of the stream afte r it has been d eg rad ed. Whether a locality see ks to protect streams for reg ulatory, eco n omic or eco- logi ca l reason s, the approach taken mu st incorporate a thoro ugh under standing of the stream 's ecological fun ctions and the val u es people place on those fun ctions. Thi s is not only critical to e nsurin g that the goals of a stream protection strategy are met, but al so to d esigning projects of an appro priate sca le, focus a nd approach . Those co mmunities that devise successfu l stream protec tion strateg ies today wi ll not only reap the rewards of healthy, desirabl e communi - ties , but will a lso avoid expensive clean - up cos ts in the future . Failure to plan is planning to fail . Why Adopt a Stream Corridor Protection Strategy? While federal and state programs man - date requirements fo r stream protec tion, su ch as prohibitions against dumping, streams cannot b e protected adequately simply through adheren ce to federal and state regulations . Despite the protec tions afforded by the CWA, en forceme nt of statutes is often lacking b ecause of inad e- quate staffing and resources to police vio- lations. Also, probl ems may be caused, not b y willful destruction or harm, but by lack of awaren ess on the part of property owners or local gove rnm ents. An example of this was a se dim ent prob- lem in a northern Virgin ia creek that was cau se d by lack of req ui site erosio n control m easures on th e part of a county utility proj ec t . A nother example was when a local creek s uffered a myst eri o u s annual fish kill. It turned out to b e th e res ult of a private sw imming club e mptying ch lori- nated wate r directly to the creek without using a holdin g pond to allow the water to d echlorinate . I n both cases, t h e law was adequ ate; it was enforcem ent that was lacki n g. A stream protection strategy can se rve t o build awareness and compli ance wit h existing regulatio n s. In both cases described above , com munity vol unteers tr ained in stream regu lations fo und and rep orted th e violations led to so lvi ng these lon g -standing pollution problems . When devising a stream protectio n strategy, it is equall y importa nt to con - sider the n eed to p la n for future protec - tion. For example, a loca l Soi l and Water Con se rvation District is currently la ying p lans for the protectio n of a creek in the Middle] ames River Watershed, so that watershed d eve lopment will n ot pre- clude u si n g it as a drinking water so urce in the future. The distr ict is not seekin g to halt development per se, but wo rking to put co n se rvation m easures in p la ce now, to miti gate excessive runoff from futur e d evelo pment. Local P l anning I ssues Many loc al planning issu es are linked to stream protec t ion , so lo cal groups n ee d to under stand how these r elate to local protection m eas ures. For example, in C harlottesvill e, Virgi nia, th e debate ov er wh ether or not to ban free -roam ing d ogs from severa l ci t y parks was more co m - pl ex than si mpl y an iss ue of public safe- t y. Moore's cr ee k , which border s so m e of the parks , is on the s tate's 303(d ) li st for clean-up because it con tains feca l co n - tamination in excess of state and fe d er a l standards. Thus, proposals for 'dog parks ' along the creek would need to co n si der th e impact on the mandated clean-up plan , in order to avoid adding more fecal co ntaminants to the creek . In the past, loca l gove rnm ent officials might n ot h ave consid ered th e impact of th e CWA on a city dog ord inance, but this is not the case today. In a s imilar ve in , local governments n eed to coordinate their ac tivities across juris - dictional boundaries. For example, rap - idly developing areas in Virginia a re inc reasingly looking t o fill water needs via inter-basi n water transfers. One co unty may eye a stream fo r future drinking water suppli es wh ile an upstr eam co unty may be planning to site a futu re wastewater treatment plant on the same str eam . Or, two states may share a la r ge water basin, su ch as the Anacostia Ri ver , whi ch drains a large portion of Maryland and the District of Colum bia , or the Potomac, which is drain ed by D .C . and Virginia and por - tions of West Virginia. Coop eration and effecti ve steward ship are n ee d ed by a ll states and lo caliti es, especiall y when watersheds are shared . The future of the C h esa p eake Bay depends on a shared co mmitment and effective stream pro - tection strategi es by all municipalities within its drainage. R egional Planning Issues Regio nal approaches to government, such as through Planning District Commissions, cannot solve watershed management n eeds, si nce these districts don 't always match watershed bound - aries. Moreover, as non -reg ulatory bod - ies, planning di stri cts can only provide ad vice; and the advice and related techni - cal assistance they give varies greatly, d e pendin g on available staffing and fund - ing. C reati ve partnership s are often need - ed b etween jurisdictions to ensure that a watershed-level strategy is d eveloped . Fiscal Considerations From a fisca l st a n dpoint, the cost of put- ting off anticipated problem s does not defray costs but actuall y increases them, A Stream Corridor Protection Strategy for Local Governments 3 sometimes far in excess of the amount that would have been expended initially. For example, the costs of treating d rin k- ing water can be far less if a com munity adequately zones areas for watershed protection now, so that expensive water treatment, land purchases and easements can be avoided in the future. Similarly, setting aside land now to allow for natura l functions may cost less than their man-made equivalent, such as large flood control structures . An often- cited exampl e concerns the wetlands associated with the C h arles River in New England. A cost-benefit analysis performed in 1972 by the U.S. Army Corps of Engineers show ed that pur- chase and protection of existing riparian wetlands on the Charl es River would prevent $17 million in annual flood damage costs, because the riparian wet- lands were far more cost-effective for flood co ntrol than the engineering alter- natives originally proposed by the Corps (1 ational Wildlife Federation , 1997). The wetlands remain protected today and co ntinue to abate flo oding, purify the water and r echarge the drinking water so urce aquifer, while providing critical habitats fo r myriad plant, ani- mal, fish and bird species. 4 Chapter One: The Benefits of Local Stream Protection Approaches to stream protection can either be comprehensive, encom- passing all streams in a jurisdiction, or they ca n be limited to addressing iss u es in a part ic ul ar watershed. In both cases , it is important to understand the current health of a stream, in-stream uses, land u ses wit hi n the drai n age area and how future p la n s may affect stream hea lth. Assessing a Stream's Current Condition Unfortunately, when considering a stream's cu rrent cond it ion, land man- agers, regulators and scientists often lack the data they need to make the best deci- sions. If a str eam has n ot been moni- tored r ece ntly, or at all , there may be lit- tle or no data availab le about its condi- tion . Even if there is annual monitoring, it may n ot adequately identify the t rue , long-term health of the stream , or it may be missi n g a contamin ant that is not identified b y the us ual s u ite of tests . The fo ll ow ing list provides an overview of the types of data on e might assess in co n sider in g stream health. While it might b e tempting to m on itor eve ry- thing in this list , there will be practical realities of time, funds and staffing . Which p aram eters sh o ul d be measu red will depen d , in part, on the goals for your strategy and what you deter mine you need to kn ow before beginning. Considerations for A s sessing a Stream's Conditio n The fo ll owin g aspects of a stream corri - dor sho uld be considered , in order to gain a pict u re of its current condition: Physical and biological characteristics • Drainage area: The la n d area drai n ing to the stream(s ), which makes up its waters h ed. • I I Ass essing a Str eam's Curr ent Condition and Futur e Impa cts Up on It • Stream health: Measurement of t h e stream 's chemical a n d b io logica l parameters, its habitat and water flow , and the characteristics of its riparian vegetatio n . • Wildlife and.fish: Animals and fish in the stream, especiall y rare , threatened or endangered spe cies. • Riparian condition : Stream buffer width, vegetation types , stream bank stability, floodplain uses and co ndi - tion , and tree canopy coverage. • Channel stability: Measurements of the stream 's channel and floodp la in, including delineation of floodplai n s and flood-prone areas, the degree of sinuosity and chann e l type. • Erosion potential : Locations and per- centages of steep s lopes, especiall y areas with highly erodable soi ls , w hi ch may contribute to excessive siltation of the stream. Land uses and zoning • Land uses: Watershed land uses and zoning , including current land uses and the potential for those u ses to impact the stream; fo r exan1p le, an oil tan k farm that may be subject to spills . • Runoff potential: T h e percentage of imperviousness, meas ured by paved area and compacted soi ls in high u se areas , which affects rates and vo lu mes of runoff and water q u ality. • Protected areas: The percentage of land under permanen t protection; for example, conservation easements an d National Park lands. • Disturbed areas : A r eas with disturb ed land needing remediation, such as abandoned surface mines that have not been reclaim ed . • Flood damage mitigation: The percent - age of land within the 100 -y ear flood - plain that is available to mitigate flood waters , versus the percentage of devel - oped land. Cultural uses • Significant sites: Historical or cult u r - ally significant sites, such as historic locks , dams and ative American encampments. • Recreational us es: Recreational uses , such as fishing, hiking , boating and access points. Health of a Stream's Aquatic Life There are seve ral factors than can affect the health of a stream's aquatic life, su ch as the makeup of the stream's water chemistry. For example, acidity leve ls may affect the type of algae present, which in turn affect the type of aquatic insects and fish that can thrive there. Similar ly, lower oxygen levels and high er temperatures can provide breeding grounds for the development of water- borne diseases. A sound monitoring pro- gram should seek to combine measure- m ents of the stream's chemical, biological A Stream Corridor Protec ti on Strategy for Local Governments 5 stream cha 111el feature s Edg e of floodplain ~~ .:• and physical health, in order to accurately assess problems with an d threats to the stream, and to design an effective remedi - ation or protection strategy. Measuring aquatic life The co m position and distribution of a stream's aquatic life provides an indica- tion of the stream 's health. Fish are a useful indicator of this. The distribution of juven i le fish within a stream can indi- cate its h ealth, as can the distribution and wealth of fish species. Other meth- ods, such as fish tiss u e analysis, can also be used to determine if there are sources of toxic pollu tants in t h e stream. T he Index of Biologica l I ntegrity is one measu r e used to evaluate the diversity of a stream's aquatic life. Organisms, s uch as macroinvertebrates (aq uatic insects and their larvae) and crustaceans, can provide usefu l ind icators of a str ean1's conditio n. Many, suc h as the wi nter stonefly, are very sensitive to pollutants and some agencies use their relative abundance and diversity, or their absence, as an indicator of stream health . Biological monitori n g of aquatic organisms may also show im p air- ments missed by other methods. For example, a 1988 study done by the Ohio Environm en tal Protection Agency states that, whi le the presence of a water pollu - tion imp airm ent in a st ream was detected 64 percen t of the time u sing just chemical monitorin g, biological monitoring showed impairment 94 percent of the time when the stream was impaired . Reference conditions Water q u ality standards for a stream's aquatic life are based u pon reference con- . ditions. A stream within the general area , though not necessari ly within the same watershed , and which is considered to be representative of optimal local ecological conditions, is used to devise a standard, against which other streams can be com - pared . The advantages of this system are that it allows different standards for tidal streams, coastal plain streams and mountainous headwater streams. These three types of stream naturally vary in terms of their population s of macro in - vertebrates , fish , and plant species a n d habitat conditions . However, the reference condition approach has limitation s. If there are n o healthy str eams in the region , as may b e the case in a heavily urbanized or subur- ban area , standards may be set lowe r than are desirable or possible. Also , human interpretation of those r efe ren ce stan- dards can vary and may b e erroneo us. Habitat Concerns In addition to the need to meet min imum wate r quality standards, hab itat should a lso be considered as a critical aspect of stream health. A stream may meet chem - ical water quality standards but lack the req uisite habitat needed to support cer- tain fish species, such as trout that require deep pools, runs, riffles and over- hanging roots and vegetation to provide cover from predators. In addition, high stormwater flows may be scouring the stream bed and banks, preventing co lo- nization by aquatic insects or the devel - opment of fish spawning beds . Morpho logy of the stream channel A stream's habitat may also be impaired by physical a lternations s uch as channel - ization, armoring the streams banks with concrete , metal or riprap, dredging the stream bottom , or putting in road cross- ings, culverts and stormwater outfalls. While these uses may be legal, they can impair water quality. Resource man agers should consider options for their removal, mitigation or replacement with environmentally beneficial structures, such as bioengineered approaches. The morphology of the stream chan n el - its shape, the percentage of its course con- sisting of riffles and runs, its sinuosity and the degree of stream entrenchment (carvi n g of an over-deep chan n el and steep banks )-can all be m easured to pro- vide an indication of stream bank stabi lity. The stability of the stream will affect the rates of bank erosion, floo d ing and h a b i- tat q u ality.

However, before decid- ing which stream protection strategy to adopt, it's important to understand two key considerations that should be uti- lized in devising yo ur strategy. Consid er the degree to which yo ur strategy: • protects and/ or restores native species, n atural stream banks and maintains or improves existing water quality and quantity, • protects existing non-harmful com- munity u ses, such as access for fishing or boating. If yo u don't take these considerations into account, your project probably won't achieve its maximum potential benefits and community support. To create an effective stream protection strategy, you need to consider every aspect of stream restoration , not just one or two aspects in isolation. For example, a co n - servation group so ught to restore fish habitats by adding additional pools, runs and riffles to a suburban creek that suf- fered from extreme stormwater flows. However, the stormwater carried warm, contaminated street runoff into the creek, resulting in poo r water quality and stream temperatures that were too high. Even though fish habitats were improved, water quality was sti ll inad equate to sup - port fish. The project failed to consider every aspect of restoring the stream. If the group had fully considered all th e necessary stream con ditions, it would have realized that the proj ect was unfea - sible and saved a lot of wasted effort. The best approach wou ld have been to address the need for improved sto rmwa - ter management rather than to build fish habitat structures. If you're going to implement a success- ful stream protection strategy, yo u n eed to develop a sound understanding of: • I I D eciding O n a Protection Strategy • existing baseline stream and riparian conditions, • existing regulations to protect o r restore the stream, • future land use changes that may change watershed conditions by affecting land runoff and resultant stream flows or water quality, • the effects of each change that yo u might make on the stream and ripari- an corridor . These apply whether you are monitoring the effectiveness of a n ordinance or reg- ul atory framework or are monitoring the success of a particular project or site plan. If yo u want to en sure that you understand existing baseline conditions for the stream and its riparian corridor , you need to develop a monitoring m ech- an ism to gather that data. The main way to do that is to monitor the stream over a period of time. There are a number of ways you can do this, which are outlined in Chapter Two. They will enable you to d etermine how your stream is doing and to assess progress toward any goa ls that you set for the stream. Elements of a Stream Protection Strategy Once yo u hav e assessed the base I ine conditions for the stream, you need to S<Ampje Project Go<Ajs • To achieve certain water quality standards. • To enhance economic value. • To provide recreational opportunities. • To protect sensitive watersheds. • To protect current or future water supplies. create a strategy for protecting it. A typ- ical strategy lays out the general aims of the protection program and its specific goals. These goals are then broken down into targeted objectives, which can be monitored and assessed periodically to see how well the goals are being achieved. The objectives are then broken down into particular actions; for exam- ple, a project to replant a specific stretch of river bank or a project to monitor out- flow from a point source. Thus, you have a strategy comprised of: • Goals • Objectives •Actions Your strategy will probably depend upon the extent of the problem, the resources you have available and the number of streams and watersheds affected. You may, for example, decide to Elements of a Stream Protection Strategy MiSsion/V"asion /l\~ Goal 1 Goal 2 Goal 3 Goal 4 I I \ \ ~~'//\'b\~ Action Action Action Action Action Action Action Action Action Action Action Action A Stream Corridor Protection Strategy for Local Governments 9 concentrate on all the streams in on e waters h ed, rather than dissipate yo ur resources over the whole area o f yo ur jurisdiction. Alternatively, yo u may see protecting drinking water supplies as the number-one priority. So your strategy will be to protect streams that are drink - ing water sources. Consider what yo u hope to achieve with your stream corridor strategy. Are you seeking to m eet regu latory standards, protect hi storic or ecological re so urces , respond to increased flooding and prop- erty dan1age, promote touri sm and recreation, or possibly combine c urrent legal statutes so that they achieve a com- prehensive approach? It is difficult to determine a strategy without first collecti n g some baseline data. You need to co n sider what data you need to co ll ect. Yo u wi ll b e able to do this once yo u 've deter min ed a strategy. This is a bit of a Catch 22 situation, but you do need to do preliminary data col- lection first, before yo u can really decide what your strategy needs to be. Once you've establi shed yo ur strategy and goals, yo u can then return and foc u s fur - ther data-gathering aro und those goa ls. D etermining the Strategy's Approach When yo u are working out you r strea m protection strategy, yo u should ask yo ur - self questions to determine the most effective strategy for achieving yo ur objectives such as: • Will the approach be site-specific? Will we design gu id e lin es or reg ula - tions to achieve watershed protection for land-disturbing activities or pro- posed developments ? • Will we u se zoning to protect specific areas such as developing overlay zones fo r n ear-stream areas an d critical habitats? • What do current regulations req uir e ? Do they require specifi c best manage- ment practices (BMPs), such as stream buffers or areas where some, o r a ll , development is restricted ? Omn ibus approach or retro -fitt ing? An omnibus approach to stream manage- ment employs regulations that apply to all development permits. It may be usefu l for areas experi encing rapid growth, where additional environmental requirements for new development may be the most effective. On the other hand, retro-fitting existing sites will have th e greatest impact in areas that have already been developed. Voluntary approach Regulations that apply to n ew develop- ment permit re qu ests are li kely to have little impact in d eve loped urban areas. Requests for variances, planned unit development (PUD) applications or re- zonings are ways for municipalities to influence land management practices, but these approaches are "hit or miss." In already developed areas, it may be critical to apply a voluntary approach . (See the Anacostia Waterfront Initiative in set box.) This requires a system of incentives and partnerships and may r es ult in the greatest gain . Additionall y, working with individual landowners who have po litical influence may increase program effectiveness. Current initiatives and proposals As yo u develop your strategy, it is criti - cal to thorough ly understand what has already been studied, proposed a nd impl emented fo r the watersh ed. You need to learn about oth er ini tiatives and decide whether you want to partner with them. You may be able to use findings from their studies and plan s. There may be research conducted by a local co m- munity or resou rc e agency that yo u co uld utilize. Taking t im e to conduct this analysis will prevent predictable 10 Chapter Three: D eciding on a P rotection Strategy Atia.(ostia.

Since two- thirds of the Anacostia River's shores in the District are owned by federal agencies, over which the District has no legal jurisdiction, the District coor- dinated a Memorandum of Understanding (MOU) among the agencies, to engage in clean-up and coordinated development. For example, the Navy is implementing a plan to retrofit its parking lots to add biofilters, which fil- ter and clean runoff while also making the site more attractive. problems, such as losing support for a good initiative because it didn't acknowledge prior work or studies. On the other hand , if you choose not to take the approach of prior initiatives or studi es, yo u should be careful to say why. Explain yo ur rational for yo ur n ew approach. For example, that reg ulatory requirements have changed or that yo u have a more effective so lution for pro- tecting the drinking water supply. Setting Goals You should set the goals for your strategy bas ed upon the outcomes you are seeking . For example, if your strategy is to protect drinking water, one goa l may be to pro - tect and improve the health of every stream in a particular watershed . Another goa l maybe to preserve a certain level of flow in every stre am. Another may be to protect the quality of water recharging the aquifer. On the other hand, if your strategy is to promote tourism and recre - ation on healthy stream s, your goals may incl ud e enhancing the eco nomic value of the stream by improving its access fo r tourists or hikers. Your goals might incl ude meeting statu- tory requirements, providing substantial cost savi ngs to protect future water sup- plies, meeting compreh e nsive plan goals, improving community safety by pre- venting downstream flooding, and so on. This justification will be important, not only for the community, but a lso for the preamble to an y new ordina n ces that have to be passed. Mandated programs Many programs begin in re sponse to a mandated program from th e fe deral , state or local level, such as Virginia's Chesape ake Bay Preservation Act, or take advantage of availab le funding , su ch as Clean Water Act, Sec tion 3 19 funding . (See Appendix C.) For example , Baltimore County's Departm ent of Environmental Protection and Resource Management's Article IX: "Protec tion of Water Qua lity, Streams , W et land s and Fl oodp lain s," cl early sets out legislative findings of fact , s uch as statutory autho rity under the federa l C lean Water Act (CWA), state statutes and the co unty's com preh en sive plan . It also set s out oth er r elevant codes , su ch as Sec. 26-278 of Article TX that covers the preservation of n atural or his- torical features . In this doc ument, leg- islative intents are clearly spell ed out. One intent is to: "Provid e infiltration of stormwat er and maintain base flow of streams ." The scope to which these regu - lations apply is also clear. For example, the regulations apply to all proposed deve lopments that did not have building permits prior to 1991. While these are standard ordinances, the clarity with which they are articulated allows them to hold up to legal challen ges and provides a d efensible rational that can be understood by planners, develop - ers, regulators and the gen eral public . Model ordinance language can be found on the Center for Watersh ed Protection's web site at http:/ /www.cwp .org / and b y searching the web sites of other municipal - ities and state agencies. If you hope to uti - lize language from another lo cal entity, it's always worthwhile to interview a local reg- ulator or planner to learn how they might have modified or improved it in hindsight . You'll also want to co nsid er how the lan - guage conforms with yo ur own stat e and lo cal statutes and take into account practi- cal and political considerations when it co m es to adoption and implementation. Community-initiated programs Other initiatives are the result of strong co mmunity support for environmental protection . Water quality and r ec re - ational opportunities alon g our water - ways are increasingly b eco m ing major co n ce rns for many co mmunities, es p e - cia ll y in urba n or suburban areas . Many of these p eo pl e wan t to protect their streams and provide enhanced rec re- ational access to them. Wheth er yo ur strategy is the result of legal r equirem ents or a community ini- tiative , it s ho uld attempt t o address a ran ge of stream protection issues, rathe r than limit itself to only one. This n ee d - n't be m or e expen sive or time -co n s um - ing, b ecau se an holistic approach to str ea m manage m ent may save you a lot of money in the long run . If your coun - ty 's land u se zoni ng r es ults in a sever e drop in water quality and pollution of th e aquife r , it co uld cost yo u a lot more to put right than if yo u had consi dered the full ran ge of effec t s and potential benefits that a compr eh en sive a pproach may have achieved. Similarly, a lo cal co mmunity may have equal conce rns that co uld be m et at the same time, pro - viding lo ng -t erm cost cutting and co m - munity support. For ex ample, the stormwater program might include buffer zones that provide much -need ed rec r eational facilities for a su burban area. Whatever the case , you should take the time to fi nd out all the potentia l co mmunity goals that co uld be met by yo ur strategy. There co uld be all so rts of added b e n efits that yo u haven 't thought of. As a result, your strategy should be flex - ible and open . The methods yo u employ should aim at achievin g multiple goa ls, rathe r than a single goal. This wi ll allow yo u to be more r es ponsive to local com - munity input and to altering yo ur objec- tives and actions if you ne ed to. For exampl e , you might initiate a program in ord er to improve stormwater manage- m ent, but then find tha t local people are just as concerned about habitat enhance- m ent and fish restoration. You can then alter your actions to e n compass all three co n cerns . An example of this approach is in Albemarle County, Virginia, where the stormwater ordinance includes g uid elin es for applying bioengineering techniques that improve fis h and wi ldlife habit at. Your goals will determine a p roject's specific objecti ves, its timing and the reso urces (e .g. st aff, time, studies, and con stru ction ) n eeded to achieve it. For example , if yo u are drafting new regula - tions, clearly articulated goa ls are critical both to building s up port for your initia- tive and to e n s u ring that relat ed obj ec- ti ves and actions wi ll ultimately meet those goa ls . Setting Objectives The n ext question to co n si d er is, "Based on yo ur project goa ls (e .g. protec t water qua lity ) what are the objectives that will achieve those goals?" For example, are yo u seeking to protec t water qua lity throu gh r es torati on, enforcement, new zo ning? One objective m ay be to develop a process for responding to future crises, s uch as ch emical s pills . Another might b e to prevent your stream 's li st ing under th e fed eral Clean Water Act, Sectio n 303(d) as not m eeting d esignated uses . A Stream Corridor Protection Strategy for L oca l Governm ents 11 Whatever objectives you choose, they can go beyond simply responding to potential crises or statutory require- ments. For example, if a stream is on your state's impaired waters list and requires the establish m ent of a manage- ment plan to clean it up , you might take the opportunity to identify and achieve r elated objectives , s uch as the restora- tion of riparian wetlands or establish- ment of riparian buffers. These other objectives are compl imentary to the pri- mary obj ective , becau se they wi ll se r ve to clean the water, provide wildlife habi- tat and create opportuni ties for public recreation, visual enhancement a nd stormwater management. project timetrame Identifying key riparian protection objectives The fo llowin g list of key objectives will help yo u determine what specific objec- tives yo u may wish to adopt to achieve your goals. These objectives may not all be met by any one project. However, if you do consider them all , it will help ensure that you take a comprehensive approach to stream protection. There are a numbe r of k ey riparian objectives that every stream project n eeds to consider, especially when water quality protection or r estoration is a pri- mary goal: • Native communities: Protect and restore native ecologi cal communities -plant, animal and fish species indigenous to the str eam. • In-stream habitat: Protect and restore natural in -stream habitats -str eam banks, in-stream substrate, vegetation , r iparian vegetation and stream cover. • Stream form and function : Preserve or restore the natural str eam morphology consistent with local conditions, to ens ure that stable stream banks and habitat are preserved. • Riparian hab itats: Protect and restor e stream buffers . • Water quality: Set standards for allowed uses or discharges that will maintain or improve existing water quality. • Stream .flows : Ensure adequate stream flow for animals, fis h and recreation, that w ill prevent extreme stormwater flows b y keeping impervious cover to Year 1 Year 2 Action A Action B Action C Action D less than 2 5% (ideall y, to less than 15%) and that seek to provide addi - tional infiltration areas. • Access: Identify, protect and improve existing, appropriate access poi nts and provide new access points, where appropriate, for people or animals . • Floodplain: Restrict or prevent devel- opment within the 100-year flood- plain and protect floodplain habitats . • Wetlands: Protect and restore riparian and non -tidal wetlands, in order to ensure that water fi ltering, water stor - age and habitat functio n s are preserved. Timeframe Your strategy should identify clearly when you plan to achieve specific actions that will achieve your goals and objectives as we ll as a tim eframe for assessing your progress and modifying your project as needed. If you are taking a pilot or demonstration phased approach, be clear as to when yo u wi ll take the project to full implementation (the whole watershed or county) and how it wi ll b e monitored and adapated as needed.

Will the approach seek to protect all the streams in a partic- ular jurisdiction, for example, a co unty? Will it be limited to str eams in eco logi- cally sensitive areas? Or to locations set aside for preservation or new develop- ments? Whether you decide to take a broad approach that addresses all the streams in yo ur locality or limit yo urselves to a particular strean1, it's still necessary to take a watershed-wide approach to any protection strategy. Watersheds vary in scale. The watershed of a small headwa- ter stream could be as littl e as a few ac res, but it may be part of a much larger river's water shed, say of 150,000 acres. Another consideration is the size of the stream itself, which is defined by the size of the stream's watershed. Streams are often referred to by their relative position in the drainage network . Small headwater streams are.first-order streams, larger streams fed by two or more first- o rde r tributaries are second-order stream order diagram Fi rst Order Third Order Fourth Order streams , and so on . Watersheds can a lso b e re ferred t o in term s of their rank. First-order waters hed s, for exam pl e, are e mpti ed b y fir st -order strea m s; seco nd- order wa tersheds e n co mpass the drain age area of a second-order stream and its tributaries. Different approaches may b e needed to protect firs t -order headwater str eams than t o protect fifth-order rivers, which drain a much larger area . A whole-watershed approach requires consideration of the watershed's drainage a r ea, land u ses, land cover , geology and hydrology. For instance, if a com munity decides to co nduct a fish habitat restoration project, b u t does n ot con si d e r the impact of stormwater runoff from a large shopping m a ll in th e upland porti on of the drainage, the proj - ec t may fail. Similarly, a stream buffer enhancem e nt program will not achi eve water qua li ty goals if st ormwater pipes that discharge d i rec tly into the stream are not addressed. Local co mmunities n eed to consider whether the stream to b e addressed flows throu gh more than one j uri sd ic- tion, which is often t h e case. Regio n al entities, such as the M etropo litan Washington Counci l of Governments, which se rves the Washington Metro region , can b e helpful in coordinating j oint initiatives. Howeve r , applyi ng leg al tools across jurisdi ctions is more complex and the best approach will probably b e to utilize voluntary initia - Ian.

In cases where a str eam flows fr om on e juri sdiction into another , you may need to work together to en sure effective management of the river. For example, if the downstream locality plans to utili ze the wat er for drinking, fishing or recreation, the d ownstream jurisdiction might offer in centives to the upstream jurisdiction. It might offer to purchase development ri ghts, share resources o r r evenues, p lan joint to uri sm ventures or offer other incentives fo r cooperation. Pilot or D emonstration Proj ects You may wish to conduc t a stream pro- tection project on a pi lot scale to tes t o ut n ew technologies o r r eg ul ations before yo u begin the main project. For exa m - ple, consider applying a n ew storm water ordi n ance to one priority watershed first , or demonstrate a r iparian ease m ent program j u st fo r headwater str eams before taking on the entire watersh ed . This wi ll enabl e yo u to work out techni- cal , legal an d political iss ues on a sm all er scale and en sure su ccessful implem enta- tion of the full program in the future. Another a pproach may b e to co nduct d emon strati o n projects to provide r e plicabl e models or to fi eld test approaches b efore implem en ting them throughout the watershed. A demon - stration project can a ll ow localities to ex p erim ent with imple m e ntatio n strate- gies and to direct limited resources to the most cr itical or endan gere d water sh ed s. If yo u take this approach , conduct an assessment of th e water sheds within the cou nty or region to determine which stream s wo uld most benefit from a tar- geted approach . It's important to note that targeting the most endan gered or po lluted watersheds may not yield the greatest return, nor necessarily be a p rac- ticable model. For example, a water shed t hat has experi en ced some development, but where impervio u sness is not yet exceeding leve ls that ca n support sen si - tive fish , such as trout, may be a more s u ccessful choice for a pilot approach than one which is already suffering from ex treme development pressures . The following table wil l help you decide w h at approach is appli cable to yo ur situa- tion . There are some approaches for situa- tio n s where time investment is high but technologica l resources are low . There are other s where the opposite is true . And other s where both are high . When review- ing th e chart , keep in mind that X s refer to potential objectives .

It has been estimated that riparian buffers can remove twenty-on e pounds of nitro- gen per acre each year , at a cost of 30 cents per pound, and rem ove approxi- mately four pounds of phosphorus per acre annu ally, at a cost of$1 .65 per pound. Contrast this with a cost of$3 to $5 per pound -$10 mi ll ion annuall y - spent by wastewater treatment facilities in the Washington D.C. area (Chesapeake Bay Riparian Handbook, A guide for Maintaining and Estab li shing Riparian Fores t Buffers, May 1997). You also need to co n si der how to "pick the lowest-hanging fr uit ," at least initial- ly. You may be able to achieve some easy tasks re latively quick ly. These wil l hel p you demonstrate early su ccess and build community support. You'll want to begin by considering the results of your resource inventory. For example, which areas are the most endan - gered and n eed to be protected before key habitats are lo st? Which areas wo uld it be cheaper to protect now, through purchas- ing fee-simp le easemen t s today, when land val u es are lower? The costs and potential benefits of each strategy should be documented before you begin, to help make the case to plann ing commissioners or boards of supervisors. Considering the Adequacy of Existing Programs A key question to co n sider at this junc- ture is wh ether you need to: • create a new program • strengthen an existing program by adding additional coverage or enforce- ment mechanisms • create an overarchi n g ordinance that applies to myriad related ordin a nc es This question can be answered in part by considering your objectives. If the streams you wish to protect are located in a rapidly developing watershed, it may be very effective to create an ordi- nance that applies to new developments. In an already developed watershed, however , this approach is unlikely to have far-reaching effects. You may d ecide that it 's more politically feasible to impl ement a n ordinan ce on a pi lot basis, in order to work out potential problems or to gain community accept- ance . For example, you could apply a county stormwater ordinance or buffer program to a limited watershed or town in its first year, then expand it once the pilot stage has been completed. You may find that, over time, yo ur municipality has enacted piecemeal environmental protection regulations that leave gaps in coverage or, in so me cases, provide conflicting guideli n es or requirements. Rather than pass yet another piece oflegislati on, consider whether these myriad ordinances can b e folded into one omnibu s regulation, which can provide both universal cover- age for relevant activities and a clear statutory authority for monitoring and e nforce m ent. In states such as Virginia, yo u will need to ensure that yo ur ordi - 14 Chapter Three: D eciding on a Protection Strategy nance does not exceed the authority granted by the Legislature , as required by the Dillon Rule. Assessing existing conditions Whether or not the existing approach needs to be modified depends on how we ll it's doing. If the streams are sti ll polluted, fish populations are not recov - ering and silt and sediment runoff are sti ll high, then a new approach is clearly needed. You can find this out by making a com- prehensive review of existing regula- tions. The state of Pennsylvania, for example, created the June 2000 Growing Smarter initiatives. These amended the Municipalities Planning Code to con sider land -use plans and zoning ordinances when issuing Department of Environmental Protection permits. This was because they felt that a more com- prehensive approach was needed . Additionally, you should see whether, in fact , you already have good ordinances in place, but they are not fulfilling their promise because variances are often granted . You can work with elected offi - cia ls to amend the ordinances and delete the number and kinds of special use per- mits or varian ces allowed . Staffing A final consideration is whether you have the staffing to implement the intent of an ordinance. For example, an ordi - nance that has clear enforcement requirements will not be effective if there are no staff to carry out inspections or enforce penalties for vio lators, es p e- ciall y for those who are repeat vio lators. You should also consider what require- ments you need to site, manage and monitor your approach. For example, in the case of stream buffers, although com pl ex formulas involving slope, soil ero dability, stream order and other fac- tors can be u sed to determine ideal buffer widths, a lack of adequate staffing to apply these criteria may n ecessitate the us e of a less scientific, but more practicable, uniform stream buffer width. If resources are low and political support for new ordinances is difficult to obtai n , consider putting your energies and staff time into ed u cating riparian landowners about the benefits of censer- vation easements a nd sponsoring work- shops to get vo luntary participation . Building Community Support Agencies charged with strea m protec- tion, such as state natural r eso urce man - agement agencies and reg ulatory enti - ti es, are aware of the n eed to protect streams . H owever , county b oard s of supervisors, planning commissions, ci t y counci ls, and other government entities may not hav e a visio n or clear set of o bjec tives for protectin g lo ca l water reso urces. Although some co mmunities are becom ing aware of the need for st ream protection as public wate r sup - plies dwindle and private well s dry up b ecau se of excessive withdrawals, it may b e too late to consider a ri ver as a drink - in g water supply o nce it h as alread y bee n contaminated. In addition to water supply and regula - tory concerns, there are other u ser s and constitu e n cies you ca n look at, su ch as recreational users, river landowners, farmers, tourism bureaus, and lo cal con - servation groups, all of whom have con- cerns about how the river is used and protected. Sometimes, good ideas fail to move forward simply because the re has - n't been an effort made in advance to engage the community. You also n eed to talk to people who may be opposed to yo ur ideas, to understand and deal with the ir co ncerns. Yo ur com- munity is likely to be made up of dis- parate interests , some of which may be in conflict with yo ur proposals and some of which may b e in ag ree m ent. Si n ce mu ch of the strean1 corridor and its watersh ed are likely priva t ely ow ned , yo u n ee d to m eet with these landowners and add ress t h eir needs and concerns as well. See k co mmunity buy-in to yo ur pro - p osed strategy or conce pt . Develop a strategy for full publi c parti cipation that includes: • community forums • surveys • leafl ets or a n ews lette r • pho nin g local lan down e r s and asking their o pini on • writing letter s to your local newspaper The re are m a n y other ways in w hich yo u ca n involve the com munity in yo ur process. Be imaginative! You may gai n gr eater co mmunity s u p - port by co mbining multipl e project goals . You can also ex p a nd yo ur b ase by m eeting with other agencies and organi - zation s to determine th ei r n eeds a nd see whether a co mbined approach wo uld m ee t eve r yo n e's objectiv es . For exam - ple , yo ur loca l Parks and R ecreation D ep a rtment may n ee d easements for a future gr ee nway trail , or want boatin g or fishing access to the stream. One of your objectives should be to engage the whole community in the dis- cussio n . You may find unexp ected new angles on your strat egy. For example , yo u may di scover that boatin g access is a key concern and that adding so m e canoe launches will h elp build support for the proj ect in the recreational community. You might achieve yo ur water quality goals by lim iting access to just a few pro - tected access points , as opposed to multi - ple , unimproved access points throu gh - out the strea m corridor . Or you might find that a local historical society wants to emphasize historic locks and t ow paths a long the river. Expand in g the project to include interpretive signage for cultural re so urces may help gai n support from these groups, as well as provide addition - al educational ben efits for the public . Broad ening yo ur goals to include a wide range of co n cerns can brin g in additional funding . For example, a proj ect that includes a r ive r trail may qualify for fund s from the Fed eral Highway Administration under the Transportation Equity Act for the 2 1st Cen tu ry. Adding h is tori cal interpretive signage may a ll ow you to use o ther fun ding sources, perhaps fr om a state hi storic resources age n cy. Yo u also stand a better chan ce of gaining the p artici p ation and respect of key ripar - ian landowners by doing this . For exam- pl e, the Rivanna River Greenway and Trail in Charl ottesville, Virginia , was made possible through the combi ned vis ion of homeowners who li ved along the river a nd w h o donated permanent ease m ents across their land , and the city's Planning Department. These two groups work ed together to m ake the vision a r ea l - ity. The Rivanna River now for m s the boundary for Riverview Park, a wonder- fu l community asset flowing throu gh the city's most visited park. Holding a public even t , s u ch as a water- shed for um , builds awaren ess of issues s u ch as water supply, stormwater pollu- tion, zon in g, low impact d eve lopm ent and other concepts that the community needs to und er stand . It can then help diverse int er ests to co n si d e r the commu- nity 's priorities and approaches for addressing them. In the Rockfis h River wat er s h ed in Nelson County, Virginia, a co mmunity watershed forum helped build community support for a stormwate r o rdinance -something the cou nty didn't have b efore . D esig ning s u ch an eve nt and process is covered in th e h a ndbook "Community Watershed Forums , A Planner 's Guide" (See Appendix A.) You also may want to co nduct a co mmu - nity survey of issues and concerns, a foc u s group , or an interview process with key stakeholder gro ups to eval uate areas of conce rn , misunderstandings and dis- agreement, as well as areas of con se nsus . Concerns of Key Constituencies A s you co nsid er your strategy for stream protection , b e aware of common con - cerns voiced b y key co nstituencies, such as farm e rs and urbanites. Agriculture occupies thirty p erc e nt of the land in the Chesapeake Bay watershed and is of crit- ical conce rn for many stream buffer pro- grams. However , many farm e rs are apprehensive about these programs and A Stream Corridor Protection Strategy for Local Governments 15 regulations. They fear mandatory requirements for a one-size-fits-all buffer width. So, when you create ripari- an buffer regulations, it's important to realize that farmers can impl ement other BMPs beside riparian buffers to achieve watershed protection goals. These include nutrient-removing cover crops and nutrient management plans. For urban constituencies, pollutant removal is frequently cited as the main reason for installing urban stream buffers. However, for forested buffers to work effectively, water must cross them either as sheetjlow or through shal- low groundwater . Research has shown that it is difficult to maintain sheetflow over distances greater than 150 feet for pervious areas and 75 feet for impervi- ous areas. In urban areas, impervious surfaces cause water to run off quickly into stormsewers or open channels that discharge directly to the stream, cau sin g stream banks to erode and defeating the purpose of the buffer. The primary reason why rural forested buffers work is that large pervious areas bordering a stream help water se ttl e more evenly into the gro und , allowing soi l and vegetation to remove a greater amount of pollutants. Usually, so m e type of structural BMP is n eeded to help stormwater settle slowly and remove pollutants before they enter the stream. Although urban stream buffers are not as effective in removing stormwater pol- lutants which reach streams through storm sewers that discharge directly to streams, they are importan t for wildlife habitats , to stabilize eroding stream banks, and to provide aesthetic values and urban gree n space. If the urban buffer encompasses a headwate r stream , spring or wetland area, it can signifi- cantly protect water quality at the source. For example, a small tributary of the Anacostia River in Washington D.C ., whose spring and h eadwaters are bordered by fo r ested national park lands , contain s stoneflies -a pollution- sensitive aquatic insect that few people would expect to find in such a highly urbanized c ity. When it comes to the creation of forest- ed stream buffers, dense urban areas bring another set of concerns. In the District of Col umbia's Department of Health, Watershed Protection Division 's Riparian Forest Buffer Strategy, the fo l - lowing concerns were raised: • Insufficient communication with, and training of, maintenance crews res ults in tree fatality and the mowing of pro- tected areas. • Vandals remove signs designating no- mow lines, remove trees and break fences. • Animal herbivory was often over- looked and as a result, trees were not 16 Chapter Three: D eciding on a Protection Strategy protected from animals at their most vu ln erable stage of growth. • There was an outcry that n atural or "wil d" areas provided habitat for criminal activities. To address these issues, the Watershed Protection Division proposed the fol - low ing solutions: • Employ contractors for large riparian forest buffer restoration sites that are being establi shed in the final phases of a contracted stream or wetland restoration. The b enefit of this is that many contractors provide a time-lim- ited warranty that protects their work . Since the first one to two years after p lanting is the most likely period for p lant mortality, survival through this period ensures higher long-term sur- vival rates. • Where riparian forest buffer plantings border res id ential areas, employ plant- ing designs that cater to community desires for a landscaped "look" and a landscape design that discourages criminal activity. • Encourage volunteers to routinely monitor riparian planting sites for vandalism and other maintenance issues. The need for watering, weed ing and replanting will provide yet anoth- er opportunity to involve the commu - nity in riparian stewardship. The following tools are intended to help lo cal gove rnment staff, planners and oth- ers co n si d er which ap proach es and strate- gies will be mo st effective in their locality. So m e approaches require greater fundin g or technical ca pabil ities, while others may r eq uire the adoption of new reg ulations or r equire a voluntary approach . Advice on the effec tiveness of the tools is derived from the advisory co mmittee for this g u ide , as well as finding s in the relevant technical literature. The approach, or combination of approach es, chosen depends upon legal require- ments, staffing and t ec hni cal capabili - ti es, and politica l co nsiderations. Detailed specifications for design ar e n ot co ntained h erein , as they a re abundant in other literature and are outside th e sco p e of this guide. Howeve r , the fol- lowing list of tools avai lable in each state within the Chesapeake Bay drainage can h e lp yo u determine which ele ment or co mbination of approaches will h elp you r eac h your goals . Of the three states that contain the C hesapeake Bay wate rshed , Pennsylvania provides the cleares t authority for lo cali- ties to create local stream protec tion ordi - nances. It does this through its Municipalities Planning Code (MPC). This code gives primary res p on si bility for reg ulating land u se and de velopm ent to local municipal it ies. U nder it, land can be zoned and d esignated for appropriate u se. Section 603 of the MP C specificall y authorizes local governments to reg ulate, p e rmit, prohibit, restrict and detem1ine u ses ofland , including wetl a nds and npar1an zones. Amendments to the MP C in 1988 ex press ly gave local governments the authority to plan and zone for the pro - tection of river s. The cod e states that zoning ordinances must b e designed to "promote, protect and facil itate ... preservation of the natural , sceni c, and I I Tools for a Str eam Protection Strategy historic valu es in the environment and p reservation of forests, wetlands, aqu ifers and floodplains." (MPC Article VI, § 603). Al so in 1988, th e Environmenta l Rights Amendment o f th e Pennsylvania Constitution (Act 1 , Section 27 and 28 ) was adopted. This amendme nt express ly gives local gov- ernm ents the authority to regulate the protec tion of streams and riv er s. In 2000, "Growin g Smarter" initiatives were sig n ed into the co d e throu gh Acts 67, 68 and 12 7, which provide state agen- cies with add iti o nal lega l authority to consider loca l zoning ordin ances and compreh en sive plans when making ce r - tai n perm it and fundi n g d ecisions , such as fo r NPDES Sto rmwater Constru ction . In Virginia, under the Dillon Rule, local - iti es can only u se the powers expressly granted to th em by the state legislature. While t hi s e n ab les so m e d egree of con- sistency in p lanning, it may al so hinder application of so m e p lannin g tools, su ch as the tran s fer of d eve lopment rights, which is n ot allowed b y the legislature . H owever , the Com monwea lth of Virginia d oes provi d e a uthor ity for zon- ing by lo caliti es. In so me instan ces, there can be co nfu - sio n whe n differ ent state agencies over- see diffe re nt reg ul atio n s for simi la r iss u es. Often, these regulati on s co ntain different d e finitions fo r th e sa m e iss u e or process . For exam p le, in Virginia "land d evelo pment" is d efined one way unde r the Erosion Con trol L aw, w hi le "d evelopm ent" has a differ ent definition unde r the C hesapeake Bay Preservation Act . It can b eco m e administratively dif- ficult for legal s taff to so rt out all the dif- ferences. Although this doesn't make th e creati o n of str ea m protection ordi- nances imposs ibl e, it doe s require a stron g co mmitme nt on be h a lf of lo ca l st aff to en sure they have the required a utho rity fo r implementation. Tools That Apply To Every State There are a number of tools that apply to eve ry state in the Chesap eake watersh ed . These include easements, covenants, proffer s and fee-simple purchases. With a ll of them, there are monitoring needs , but yo u can meet these needs partnering with a local non -profit age n cy or local vo luntee rs. Easements and covenants A stream-protecti o n ordinance may in co rpo rate methods of perpetual land- use protection , s uch as easements or cove nants. Ba ltimore County, Maryland , for example , requires dedication of a b uffer either by easement or cove nant. This dedication is requ ired for construc - tion permits in riparian a reas. If, as in Baltimore County, buffer s are dedicated free of charge to the local government, they can provide an economical way of providing protection to critical stream - si d e areas. Usuall y, su ch easements or covenants do not provide for public access to the dedicated portion of land . Although they co uld b e written to ensure public access, s uch a pol icy would proba- bly ca u se substan ti a l r esistance from pri - vate landow n ers. Easements tailored for streams While there are mechanisms and stat e- sp on so red programs for easements , an easem ent program tailored fo r streams may be a u se ful approach. The nee d for a str eam -based easement program is likely to arise b ecau se some ease m ent programs seek large tracts of land (g reater than 100 ac res) and sm all er , narrow, stream-corri - dor easem ents m ay not fit within the pro - gram's g u idelin es. In r ecogniti on of this, Virginia's Thomas J effer so n Soil and Water Con se r vation District holds ripari- an ease m ents fo r stream s to improve and protect water quality. Non -p rofit river co n servation organiza - tio n s may be interested in h old ing nar - row easem ents along ri vers. Local gov- A Stream Corridor Protec tion Strategy for L oca l Governments 11 ernments may consider partnering with these co n servation groups to obtain easements a nd monitor them. For exam- ple, both the ational Committee for the ew River and Friends of the Rivers of Virgi ni a hold conserv ation easements on the ew River. Continual monitoring Local governments sho uld be aware that simply holding an ease ment on a piece of land is not sufficient to ensure its protec- tion -even if the easement was written expressly to provide for environmental protection. Local governments holding easements on land need to continual ly monitor them to co nfirm that landowners are complyi n g with the term s of the ease- ments. The drain on staff time required to monitor sites can be prohibitive. An alter- native is to partner with a local non-profit agency, which will sho ulder some, or a ll , of the responsibility for holding and monitor- ing easements. It may be necessary to pro- vide them with grant funds to cover their time and for appropriate legal services . Proffers In Virginia, although buffers cannot be required of n ew developments unless under an existing ordinance, they can be offered as proffers by a d eveloper. Proffers are only allowed in cases of rezoning and cannot be required by the government . Rather, they must be offered voluntarily by the developer. The community sho u ld m ake the case that the buffer would serve the public and spell out its purposes and gui de- lin es, so that a developer is aware that he can proffer a buffer i n exchange fo r exception s to development restrictions. Fee-simple purchase In some cases, a local government may find it beneficial to purchase stream-side land outright. It mig ht want to create a linear park with publi c access or a strate- gically important site with a high degree of environmental sensitivity or publi c va lu e. The local government can pur- chase land from a vo luntary seller. An advantage of this approach over ease- ment purchase is that the local govern - ment has complete co ntrol over the giv en parcel. Disadvantages are raising the funding required for the purchase an d potentially needing to apply lo cal govern- ment powers of eminent domain over un willing sellers who hold key parcels. Development Rights There are two ways development rights can b e used to protect str eams and their buffer zones. The first is through Transferable Development Rights (TDRs) and the second is throu gh Purchase of Development Rights (PDRs). Transferable Development Rights TD Rs occ ur between two entirely sepa- rate parcels of land. They are allowed in Penn sylva ni a, under its 2000 amen d - ments to Act 24 7 and they are allowed in Maryland. For example, Montgomery County, Maryland, has implemented a TDR program since 1980 that has pro- tected 39 , 180 acres. However, TD Rs are not presently allowed in Virginia. Since TD Rs can cross municipal bound- aries, municipalities can agree to set up sending and receiving areas from one jurisdiction to another. In this kind of system , development credits are sold by a landowner in a sensitive area (also ca ll ed a sending area ), in order to reduce the deve lopment potential for that land. They are given to a landowner in an area designated as appropri ate for addition a l density (a receiving area). Local gove rn - ments may choose to use TD Rs if a required buffer is very wide and its regu - lations very strict. While TDR programs are effective in preserving natural resources, they have been primarily used in urban settings. According to a study, their use has not been without problems or controversy. There must be clear sendin g and receiv- ing areas. Where considerabl e sprawl exists within the sending area , it may be too late for a TOR program to be s ue - 5amPl8 criteria lisl for Ille PW'Chase of develoPment riVhlS for stream corridors Award 3 points if the land fully meets a criterion, 2 points if it mostly meets a criterion, 1 point if it somewhat meets a criterion and 0 points if it does not meet the criterion at all. The land is adjacent to a waterway that is significant for one or more of the following reasons: • It conta ins threatene d or endangered species . • It contains critica l reso urces, such as drinki ng water or trout habitat, a se nsi tive headwate r stream , and so on. The land represents a diminishing resource; for example, it is the last remaining wildlife habitat along a creek. The land contains unique cultura l and historical aspects; for example, it has historic locks and dams or Native American burial mounds. The land is subject to environmental hazards, making it a poor candidate for development ; for example, it is subject to frequent flooding, poor drainage or unstable soils. The land is located far from an available or adequate infrastructure; for example, there are no adequate roads, sewe r or septic systems, or water supply. The lan d repre sents a signifi cant com munity resource; for examp le, it is currently being used by the community (e.g. for environmental education , fieldtrips or fishing). There is a high likelihood that the land wi ll be developed in the next ten years . *Opt iona l: Development ri ghts can be purchased at an affordable (or be low market ) price. Tolal Points TOTAL: 17 or more points= high priority for the purchase of development rights . 10-16 points= medium priority for the purchase of development rights. Less than 10 point s = low pr iority for protection. 18 Chapter Four: Tools for a Stream Protec tion Strategy cessful because residen ts withi n the receiving areas may object to the higher density n ecessary for a TOR program. Purchase of development rights PD Rs are allowed throughout the Bay states. Their use is appropriate whe n it's not possible or politically desirable to remove development rights in buffer areas. This may be the case in areas where a more restrictive buffer is neces- sary to achieve environm ental or social goals, su ch as protecting endangered mussels or I ative American sites. States vary greatly in the funding they provide for PD Rs an d some lack ade- quate criteria or funds to assess whether or not a site is suitable , or strategic e nough , to acquire its d eve lopment rights. If limited funds are availab le, development rights for riparian lands should not be based simply on who applies. Rather than responding to applications, criteria should be devel - oped for environmental goals that are clearly delin eated and ranked, so that most the appropriate si tes are protected first. The table Samp le Criteria List for Purchase of Development Rights for Stream Corridors lists the criteria you can utilize to develop your own ranking system for a PDR program. Overlay Zoning One of t h e most common ways to pro- tect streams through local government law is to incorporate water protection provisions into an existing zonin g ordi- nance . Usually, the protection measures are written in to an overlay zone that is geographically specific to the stream. A local government can write this overlay district to in corporate values it wishes to promote. A ri ver-based overlay district might include provisions for protecting historic, scenic and natural values. It could also create a new buffer by requir - ing buildings to be set back a certain dis- tance from the stream or by placing restrictions on uses allowed by the "underlying" zones. Mitigating set-backs One way to m itigate the impact of set- backs and make them more attractive to developers is to allow them to include the buffer zone in their calculation of build-out potential, so that they are compensated for land protection with higher density allowa nces. On a large tract of land, removing a 200-400 foot strip of land along a stream from the calculation of the tract's buildable land can r epresent a significant loss to the developer. Although such a regulation is likely to pass a legal "takings" test, it will be more politically acceptable if it includes such a compensatory benefit to the developer. By allowing the developer to include the buffer area within his calcu- lati on of total buildable land (for the purposes of determining build out), a local government can protect streams without limitin g a developer's financial yield from a tract of land . Development rights are effectively transferred inter - nally from the buffer area to the rest of the tract. Also note that many lo ca l governments have landscaping ordi nances for sites both near and distant from streams. Su ch ordi nances could effectively require the planting and placement of appropriate native species within buffers. Critical areas When water-protection is not written into a zoning ordinance, the ordinance can provide for the protection of critic a l or sen sitive areas , in much the same way that Maryland's Critica l Area Act or Virginia's Chesapeake Bay Protection Act define critical areas. Loudoun County, Virginia and Montgomery County, Maryland u se this approach. This lega l tool probably requires a larger staff to define and review plans for specific criti- cal areas and to monitor and enforce implementation. In-stream habitat protection Some local ordinances co ntain specific provisions d esigned to protect valu es located in the stream itself. Albemarle County, Virginia, for instance, has in- stream restrictions for the removal of woody debris, the creation of access points and for channel modifi cation -all activities that could have a dramatic impact on in-stream habitats . In-stream regulations ca n also require bioengineer- ing to restore disturbed habitats . Water Quality Protection Ordinances There are many different types of ordi- nances that can be used to improve water quality in local streams. The guid- ance offered here focuses primarily on the creation of stream buffer ordinances. However , other types of ordinances, su ch as stormwater management, open space development, and erosion and sed- iment control , bear mentioning. The Center for Watershed Protection offers helpful model and example ordinances. (See http://www.cwp.o rg ) Combining existing regulations In some localities, there are existing reg- ulations that restrict floodplain develop- ment and tree removal, or that protect criti cal habitats. These can result in the esta blishm ent of a de facto buffer zone. However , these regulations ge n erally provide only piecemeal protection for the river system . For examp le, while floodplain development may be restrict- ed, a lack of woody vegetation withi n the floodplain may reduce its ability to buffer the stream from land-use impacts. Alternatively, if the floodplain is protected but the stream's banks are severely eroded or have become chan n el- A Stream Corridor Protection Strategy for Local Governments 19 ized and armored, goa ls for water quality and h a bitat protection m ay not b e achieved . Stand-alone ordinances vs. Zoning ordi- nances When u sing ordinanc es to protect water quality, a fundamental question arises. Shou ld protection m easures occur through zo nin g or should there b e a stand-alone ordinance? For most locali- ties, the answer to this question n eeds to be based on the structure of the local governme nt. In some areas , the creation of an overlay zone s ubj ect to the zo nin g review process might be the stro n gest means to en sure a n effective ordin an ce. For other localities , individual regula - tions mi ght be more effective. Level playing field Another question localities will need to ask when they create an ordinance is, does it create a level playing fie ld ? Often , efforts to mitigate problem s such as urban stormwater create a situation where de velop ment b ecomes easier in outl yin g rural areas that are less reg ul ated. When creating any ordinance, input fro m all affected parties, su ch as farm ers , en gi - neers and developers, is essential to en sure that the regulations address com- munity values and do not unintentionally protect one area at the ex p ense of anoth er. Enabling authority Does your local gove rnm ent have the necessary authority to impl ement ord i- nances or is there already state legisla- tion that yo u can utilize? Each state within the Chesapeake Bay drainage has a di ffe rent m echanism by which it grants enabling authority to local ities . Stormwater management However well planned, d evelopm ent increases the total area of roads, rooftops and si d ewalk s . These impervio u s sur- faces all contribute to the vol ume of stormwater that reaches local stream s during storms. Yet new d evelopmen t n ee d not necessarily equate with greater runoff if creative methods are employed to prevent it. Decreasing the effects of s tormwater runoff is vital to maintaining the health of all waterways . Concentrated stormwater not only contributes grea tl y to erosion and flooding, but also carries with it greater amounts of dissolved and undi sso lved pollutants, such as oil , road sa lts and fertilizers . Stormwater can be controll ed either through prevention or through structural methods that help to hold the water in place before it flows to the stream . Sto rmwater manageme nt facilities are designed to prevent water flowing directly into the stream, to remove pollutants and to allow water to filte r more slowly back into the ground. However , this approach is often impractical , especiall y in devel - oped urban areas, such as Washington D.C., Baltimore and Richmond wh ere more creative approaches are needed to trap and filter stormwater. There are ot her ways to tackle this issue than building la rge stormwater manage- m ent ponds (large regional ponds, often made by damming s mall streams) o r p u tting in m ul tiple small ponds . Instead , consider stormwater plans that foc u s on source prevention. T h ere are many cre- ative tools avai lable for slo wing or pre - venting runoff caused b y construction . Rooftops , especially those on larger commercial stru ctures, ca n be em plo yed as storage a nd filter areas. They can b e designed to hold water and slowly release it, mimicking n atural rates of run off. Also, they can b e planted with vegetation to store and filter water and provide bird a nd butterfly habitats. For exa mpl e , in retrofittin g an old pump h ouse to serve as a n enviro nmental edu - catio n ce nter, the Earth Con servation Corps in Washington D.C. ad d ed a "liv- in g roof." This d emon strates that eve n old er buildings can be modi fied to reduce runoff. When creati n g sto rmwa - ter m a nage m ent ordinances, both design and maintenance sho uld be considered. Because Best Management P r actice (BMP) techno logies change as time goes on , all cr iteria affecting design , sizi ng and performance should b e written in a design manual that acco mpanies the o rdi nan ce, rather than bei n g in the ordi - nance itself. This design manual can b e kept up -to-date by the local stormwater management agen cy, negating the n ee d to go through a legislative approval process when changes are made. Storm wate r B1v1Ps can be expensive to create, but are relatively inexpe nsive to 20 Chapter Fou r : To ols for a Stream Protection Strategy maintain . However, the low degree of co ntinu al maintenance ca n res ult in neg- lect. Stormwater ordinan ces require post-construction management plans th a t outline responsible parties and n ec - essary maintenance practices. Some localities might want to consider ordi- n ance language that enco urages the u se of maintenance easements . Erosion and sediment control ordinances Erosion and sediment co ntro l ordin ances ca n serve as a primary way of addressing the problem of increased sedimentation caused during constr uctio n clearing and gradi n g. However, co mmunication an d enfor cement are central to an effective ordinance. Designers, en gi n eers and con tractors n eed to be ed uca t ed about the importance of erosion control prac- tices . This can be accomplished through technical documentation that accom p a- nies the ordinance, alo n g with other education methods such as workshops . In Montgomery County, Pennsylvani a a Sediment Contro l Pre-Construction Notice is sent to all contractors . This notice out- lines the co un ty 's basic erosion control and stormwater requirements . Althou gh it doesn 't replace the actual p e rm it and plan language, it serves as a reminder of basic r esponsibilities and obligations . A lon g with strong communication a bout the necessity of erosion con trol comes the n eed for strong enforcement. To effectively enforce a ny ordinance, staff need to be able to inspect construction sites on a regular schedul e. Open space and cluster development ordinances Open -space or conservation-based development ordinances address the need for natural and cul t ural resource protection by creating zo n es for both housing and undeveloped ar eas of the stream corridor. This type of concentrat- ed development greatly reduces the amount of impervious cover on a site and h elps to redu ce t h e amo unt of clear- ing and grading needed during the con- struction process. Land areas that are left undeveloped can serve as recreation- al areas, storm water management faci li - ties and natural preserves. Local governments experien cing devel- opment pressures can foc u s growth pat- terns to protect stream and water resources. However , any ordin an ce n eeds to effectively bal an ce eco nomi c and e nv ironm ental factors, so that responsible d evelopm ent can be en cour- aged, not h indered. Don 't forg et that any open spaces yo u c reate will req uire so m e d eg r ee of m ai n - tenance. Ordinance r equirements sho ul d reflect the n eed for the future manage- ment of a ny natural ar eas se t aside b y compact d eve lopment plans . Additionall y, planne rs should wo rk with developers to link o p en spaces b et ween developments, es p ec ially along strea m co rridors, so that wi ldlife passages ar e maintained and forested tracts a re large en ough to maintain eco logical diversity. Stream buffer ordinances The abi lity of a riparian buffe r to fun c- tion to it s full potential d e pends on h ow well the buffer is planned and d es igned. The fo llowing chapter d escribes the gen - eral co mpon ents necessary for a stream buffer ordin ance. This is an overview of the cu rre nt literatur e. When designing buffer o rdinances, environmental and e n gineering staff should always be co n - sulted on the best ap proaches fo r strea m buffer design for the lo ca lity. Since local p oliti cs and land-use issues often change, it is important to have a fl exible ordinance. Since, on ave rage, ninety perce nt of buffer land is privately owned , it is essential to maintai n fl e xi - bility, if you're going to m eet different co nstituency needs and also protect water and habitat quality. The following are general features of many effective stream buffer ordinances: • Measurable criteria to d elineate the origin and b o undari es of the buffer. • The es tablishment of a minimum stream buffer wid th : 100 feet , includ - ing the fl oodplai n , is t ypically recom- mended. • Clear delineation of the buffer, both a t the site and in a ll land records . • A zo n ed approach to land uses within the buffer (if appropriate). • The abi lity to expand th e middle zo n e to include steep s lopes, wetlands a nd 100-year floodplains. • Man agement guidelines for current and future owners of prope rty in the buffer. • C lear la n gu age delineating require- ments fo r all development plans in the buffer. Fo r more on st ream buffer design a nd reg ul ation see Chapter Five . A Stream Corridor Protection Strategy for Local Governments 21 22 Chapter Four: Tools for a Stream Protection Strategy The first step in enacting a buffer ordinance is determining which streams will be affected. You can take any of a variety of possible approaches, based on project objectives, avai labl e staff and resources, and enforcement and legal consideration s. In this guide, buffer generally designates a forested buffer. A lth ough forested buffers might not be the best solution in every area of the country, they wer e the original ecosystem found along the waterways of the Chesapeake Bay water- shed and a re thus the most appropriate habitats for addressing its water quality issues. (See the box Why Forested Buffers?) In general , the inner ed ge of a buffer can be defined from the ce nterline of sm all first-or second-order streams. With wider, higher-order streams, buffer measurements usually b egin at the top of each stream bank. Ident ifying the Stream - The Perenniality Debate One of the first things a local govern - ment must decide is w hi ch streams to include in the buffer program. One cr i- terion is to include streams that flow year-round -p erenn ial streams. Stream perenniality ca n either be determined according to USGS maps, field-deter- mined eva luations, or a stream layer derived from a Geographic Information System (GI S). Another approach is to designate streams by watershed acreage; for exam ple, all streams of at least X number of acres wi ll be included in the buffer program. It's important to note that some of the smaller headwate r stream s (first order) may not show up on USGS topographic maps, yet it's critical to protect them. Identifying and delineat in g these small er streams may r equire time from local • I I Cr eating and Managing Buffers government field personal or in partn er - ship with state agencies, such as the Department of Forestry or your local Soi l and Water Conservation District. Methods for Determining Buffer Width There are several methods for determin- ing the width of a buffer. You can e ither choose a uniform width or a buffe r that changes along with stream order. Alternative ly, you can employ state-d es- ignated uses, landscape features or mul - tiple val ues that take a ll factors threaten - ing water quality into account. W.,1-f Forested BtAffers? Uniform Width One method of defining buffers throughout a locality is to establish a single, required width for all stream s. This is probably the easiest method for local governments and the regulated community to adhere to, inasmuch as it doesn't require scientific knowledge among staff members, complicated legal regu lations, or an inventory of landscape features. It 's also easy to spot violations. On the other hand , the method's lack of scientific specificity with regard to width and landscape features may be difficult to defend. Furthermore, it may Forests trap and hold sediment, filter surface and groundwater flows and shade streams to keep temper- atures lower and dissolved oxygen higher. In addition, they contribute leaf liner as food for aquatic insects, which in turn are eaten by fish. Overhanging tree roots provide fish with cover from predators and habitat for other insects. Streamside forests are also vital habitats for wildlife such as kingfishers and beaver. Historically, the Chesapeake Bay drainage area was primarily covered by forests. Native Americans used trees for firewood and canoes and maintained some lands as fields, but it was during the population boom of Colonial settlement that massive forest clearing took place. Colonial lumber exports for ship building, clearing lands for agriculture and the later use of charcoal for steam engines led to a dramati- cally altered landscape. In the early 1900s only 30 to 40 percent of the land was covered in forests. However, during the last century, much of the forests base has recovered. By the late 1970s, forested land had risen to 60 percent of the land cover. While forest area has increased since the turn of the century, the condition of that forest needs to be considered. Fragmentation -the breaking up of forest lands into ever smaller parcels for subdivisions, shopping malls and roads disrupts wildlife corridors and changes the ecosystem, altering tree species and forest health. More edges are created which allow greater opportunities for invasive species to encroach on the forest. Forests are also suffering from disease and invasions from pests such as the pine beetle and the gypsy moth. Additionally, while more land is forested today than during the turn of the century, forested land along streams is often lacking because farmers use that land for grazing or crops. In Nelson County Virginia for example, while the vast majority of the mountains are forested, most of the Rockfish River's buffer is one tree wide and root systems are inadequate to hold banks in place resulting in severely eroded 10-foot high steep, slumping banks which contribute tremendous sediment loads to the creek and fill in spaces used by aquatic insects and fish. This is one reason why the Bay agreement calls for 2,010 more miles of forested stream banks by 2010 in the Bay' watershed. A Stream Corridor Protec tion Strategy for Local Governments 23 not provide effective stream protection in areas with steep slopes, erodable soils or other sensitive habitats. A uniform width approach co uld be u sed to establish a minimum for a ll streams, along with "drivers" that auto - matically require a larger buffer. Examples for these 'drivers' are tro ut streams, the presence of threatened species and nearby higher-density devel- opments. Width is a key consideration in whether or not the buffer can be counted towards meeting the Bay Agreement's goa l of 2,010 miles of additional stream b u ffers by 2 010. Under the Bay Agreement, the buffer should be at least 35 feet wide from the top of the bank to the b u ffer's uphill edge and contain at least two tree species, shrubs or a combination of both. In Virginia, the Chesapeake Bay Preservation Act requires 100 -foot wide buffers fo r the eighty-fo ur tidewater localities that are covered by the Act and provides enabling leg islation for stand- alone ordinances for the remaining lo cal - ities . In Maryland , the Critical Area Law requires a minimum one hundred -foot buffer for all new development. This buffer must consist of natural vegetation and must stretch from the mean high- water line of tidal waters, or the edge of tidal wetlands and tributary streams. Stream Order Method A second method of defining buffer width is according to stream order, employi n g wider buffers for higher -order streams. This method requires a lo cal government to provide information to landowners in the form of a map identifying streams by their order. This may cau se disputes about those identification s. This method for defining buffer width, lik e the s in gle-width method, fai ls to take specific landscape featur es into account. Furthermore , it doesn't al low fo r lesser -order streams that have more potential to harm water quality than some higher -order streams, because of surroundi n g land uses, proximity to drinking water intake suppli es, water uses, s lope steepness , and so on. State-Designated Uses Another method for determining appro - priate buffer width relates to existing state-designated water u ses. This method appli es the legall y-designated use of the water resource, rather than the potential for harm, as th e basis for defin- #1 butter on edge of subdivision _____ _)_ ------ 24 Chapter Five: Creating and Managing Buffers ing buffers. For example, a stream which serves as a drinking water so urce would require wider buffers. This method has no rea l scientific underpinning , other than the notion that "wider buffers offer more protection ." It pays no attention to the actual compo- sition or use of the land around the water resource. This method also fails to address the way in which streams and water sheds work together as part of a larger system. However, this method is relatively e asy for a local government to implement , since it does not require exte n sive research . It may require map- ping different stream designations for stream usage in the watershed . Landscape Features Using features in the landscape, such as soi ls, slopes, wetlands and floodplains is another method that is often used to determine the width of a buffer zone, in conj un ction with other approaches. Sometimes , land features add extra width to the buffer , as in the case of wet- lands and floodplains , which can be u sed to define the limits of the buffer. This method requires careful inventories and violations may be difficult to spot . It also makes for a compli cated review process . To achieve intended goals, this method should be implemented in tandem with other methods, such as single -wi dth, stream-order or drainage -basin methods . Multiple Values The most scientifically based buffer d ef- inition method is a multiple-value approach that us es a mathematical for- mula to take all of the factors threatening water quality into acco unt. Since this method also happens to be the most time -and r eso urce-inten sive, it is best suited to a well-staffed planning office. Baltimore County, Maryland , employs this m ethod of buffer-delineation . It combines slopes and uses to determine buffer width. For example, a slope of 0- 15 p ercent for trout -use waters req uires a buffer of 150 feet, while the same str eam -u se classification with a slope of greater than 25 percent requires a 200 - foot buffer. Montgomery County also has established recommended buffers srream zones Zone l for wetlands, springs and seeps that fall outside their stream protection areas . Stream Zones One approach to defin ing stream buffers and allowed uses is to have zones with defined functions and u ses : • The first zone (the streamside zone) is closest to the stream and almost no uses are permitted except mature fores t . • A seco nd zone allows for some reg u - lated uses in the buffer, such as selec- tive harvesting of some trees, as lon g as best management practices (BMPs) are followed . • A third zone allows for somewhat com- patible uses, such as reside ntial and recreation uses or stormwater retention. The zone approach is used as a way to acknowledge existing uses while provid - ing for a wider buffer, in return for some use of the buffe r space in the oute r region (zo n es two and three). It's impor- tant to note that, as trees age, they become less effective at nutri ent uptake, which is why some programs advocate or allow the harvesting of mature trees in the second zone. However, some forest ecologists note that the presence of mature trees that eventuall y fall and decay provide an important nutrien t source for the forest. While their co ntin - ual harvest may improve nutri ent uptake by leaving only yo unger trees, it harms other functions provided by decaying material. Usually, the actual wi dth of the buffer is m ore important than whether or not it incorporates a zoned approach, especial ly for the undisturbed portion closest to the stream. If the stream is unstable and suf- Zone 2 Zone 3 fering from failing banks and high rates of bank undercutting, then trees may be lost at a high rate , necessitating a wi d er buffer to maintain even minimal canopy coverage. It's also important to note t h at a buffer will be largely ineffective in so lv - ing stream over -enrichment problems if high vo lum es of stormwater are piped directly to the stream , as is often the case in urban and suburban areas. Montgomery County, Pennsylvania, calls for Zone Two to be a minimum of SO feet wide from the edge of Zone One, or to extend to the edge of the 100-year flood - plain, whicheve r is grea ter. Zone widths and uses vary Although a three-zone b uffer system is s u ggested by the Chesapeake Bay Program, the widths and specific uses all owed in each zone vary between local- ities . For example, w hil e the state of Pennsylvania recommends the use of three zones in its statewide Stream ReLeaf Program, Montgomery County, Pennsylvania , recom m ends only two zones in its guidance for a Riparian Corridor Con servation District Ordinance , with Zone One designated as a minimum of 2 5 feet of undisturbed forest and Zone Two designated for pas- sive uses, such as wild li fe sanctuaries, passive areas of park lan d and trails that adhere to state trail design codes . It a lso a ll ows conditional use permits fo r liv e- stock crossings, public utilities , cam p- grounds, go lf courses and several other uses. Baltimore County, Maryland, also follows the two-zone approach , rejecting a passive, o r third , zone. Their guidan ce concentrates on manag in g for multiple valu es beyond nutrient removal and includes wate r quality, heterogeneity for aquatic and terrestrial communities, and maintenance or enrichment of biological diversity. As a result , their management objectives require that a buffer generall y remain undisturbed . Managing Buffers Effective management of the buffer is just as important as proper siting. A forested buffer that allows inappropriate uses that impair its functionality can ren- der it largely useless. If the buffer is not monitored and maintained it may suffer from high rates of tree disease, encroach- ments, livestock trespass, harvest o r moving of vegetation that impede or negate its ability to protect the stream. D esign Options and R equirements It is a good idea not to include many design details, such as vegetation types and placement, in a stream buffer ordi- nance. This information is subj ect to con- tinual change based on local experie nce and emerging technologies. As described earlier, an accompanying design manual or design guidan ce document, which does not require a formal ordinance revision when technical items are added or delet- ed, may be more practical. Ju st as federal and state level agencies adopt acts, and then regulations, local governments can utilize two tiers -ordinances (equivalent to acts) and design manuals (equivalent to g uid elines ). Management and Mainte nance Though forested buffers are relatively inexpensive to maintain, they do require A Stream Corridor Protection Strategy for Local Governments 25 care once es tabli sh ed. New seedlings n eed to be t ended , invasi ve species n ee d to b e removed , eros ion gullies n ee d to b e fixed , and at times , se lected harvesting ca n be d on e. Thu s, when creati n g buffe r ordinances, it's important to identify a specific li st of stru ctures, practices and activities that sho uld and should not b e permitted in a forest buffer within th e ordinance. Management P l ans A local government may r equire man - agement p lans fo r ce rtain disruptive land u ses within a riparian buffer . Common u ses for which a management plan m ay b e r eq uired a re silvic ulture, agric ulture and mining, tho u gh others exist as we ll. A loca l government with limited r esources may n ot be able to handle th e r eview process necessary for t hjs require- ment . An alternative is to req ujre that su ch uses m ee t the standards of a state agency -such as the local Soil & Water Con se rvation District office or the Department of Forestry. Tills removes the respon si b ility of rev iew from the lo cal government, whi le still providing so m e level of oversight for p ot entiall y harmful activities. Even with the h elp of these agencies, however, responsi bility for monitoring and enforcement m ay fall to the local government. Thus, the m echanism and funding for oversight must be d etermined prior to be ginning a new program . P ermitt e d Uses Buffers may accommodate the following u ses with out a substantial loss of effec - tiv en ess, provided that the impacts of such u ses are m itigated. limited harvest of trees, berries, and other non-timber forest produds Even though a forested bu ffer is more effec tive than buffer s with other types of vegetation, a local gove rnment may choose to a ll ow the selective harvesti n g of trees, berries a nd o ther forest prod - u cts without sig nificant damage to water qual ity. C learing of dead trees and non - indigenous plant species may also be unde rtaken . Clearing of trees fo r "views" should be disco uraged, unl ess it can b e shown that such cl earing wi ll n ot sign ificantl y redu ce water quality. Local governments with proper reso urces for r eview may r eq u ire a s ilvi - c ulture management plan or may require that a plan m eet approval from the local Soil and Water Conser vation Distri ct. Stream crossings Most buffer o rd inances allow for the placement of esse ntial utilities withi n the buffer ar ea, su ch as storm sewer inter- ceptors o r oth er pipes. An effective buffe r ordinance req ui res that care b e t ake n when doing this, so that thei r impact d oes n 't work agai n st the purpose of the buffer. For ex ampl e, a wide swath ca u sed by a power lin e that is sprayed wi th he rbi cides m ay h ave a major impact on the buffer 's function. Other cross in gs, s uch as fo r cattle, ca n be employed using approaches t h at restrict the crossi n g to an adeq u ate, but narrow p assage and require some a rmor - ing of the crossing, s u ch as logs anchored in the stream b ed to prevent g ull ying.

Recreational uses Depending on its goals, a local govern - m ent may wis h to allow recreational u ses within the buffer space. These may invo lve docks , piers, boat access an d trails .

Fo r example, it must be p lanted in woody vegetation or m a n aged to lead to s u ccessio n by woody vegetation; also, it must be p lanted with a var iety of vegetatio n of indige nous trees, shrubs and gr asses to enhan ce the q u a lity and q uantity of cove r , erosion co ntrol , pollution reduction and wi ldlife food value . It also p rovides a list of acceptable native plant and tree species, w h ic h is usefu l fo r land managers . This approach co uld be used alongside tax - cr edits or reimbursements, su ch as the those provided by the Conser vation Reserve Enhan cement Progra m. (See Programs in Appendix B .) If a locality wishes to create a particular- ly far-reaching ordinan ce that delin eat es the types a nd p lacemen t of vegetation , it should also allow for the removal of n ox- io u s weeds . It's recommended that this infor m ation be included in an accom pa - nying d es ign manual.

A buffer ordinance sho uld require that appropriate measures are taken to manage cattle access to streams. I deally, access should be only at certai n points and those points sh o uld be managed to preve nt t h e dispersal of manure into the stream. In many cases, controlled and stabilized access points improve cattle safety. Prohibited Uses The following uses shoul d be expressly prohibited within the buffer. These pro- hibition s are in addition to those which are already illegal. Fo r example, d u mp- ing fill m at e rial into a fl owing stream is a violation of the federa l Clean Water Act, so the b u ffer ordinan ce need not mention d umping restrictions. Mining Mining and its by-products represent a process wholly inconsistent with the p u rpose of b uffers. Pre-existing m ining operation s within a proposed buffer should be mitigated as m u ch as possible. Neither n ew mining n o r expansion of existing mines should be allowed within a stream b u ffer. In Virginia, the Department of Mines, Minerals and Energy allows sand a n d gravel mining in the b u ffer. However, most development reg ul ations do not al low mining within an established buffer zone. Commercial uses In most cases, local governments have to accommodate pre -existin g commercia l uses -water-related and non-water- related; pre-existing and new-by-right - within the buffer area. A n effective ordinance plans for mitigating the impact of such uses. I n general , howev- er, non-water related uses should be pro - hibited within the buffer space . Residential uses As with commercial uses, a local govern- men t may have to accommodate man y pre-existi ng hou ses and lot divisions in the buffer area. Local governments may wis h to consider fee-simple purchase, the purchase of easements or the use of eminent domain to acquire strategic b u ffer land when regu lation is not possi - ble . However, the purchase of land may not be an affordable option and eminent domain carries unavoidable political problems and requires proof that all rea - so n able avenues for purchase have been exhausted. A more feasib le approach is to discour- age, or not allow, new residential con- struction within the buffer. Clearing trees for lawns and "views" should be prohibited, unless it can be proven (preferably by a trained landscape archi - tect, biologist or other professional ) that such clearing will not reduce the overall ability of the buffer to protect water quality. If a ce rtain area of open space is required, the buffer area can be desig- nated as common space. Best Management Practices to Improve Buffer Performance Some agencies that require buffers don 't allow credit for the buffer as a Best Management Practices (BMPs). For example, Virginia's Chesapeake Bay Local Assistance Department does not provide credit for the installation or maintenance of required buffers . However , adding BMPs to improve buffer performance, such as enhancing tree and shrub density or adding native species within the buffer, may be eligible for credit. Best Management Practices are used to mitigate the effects ofland development or agriculture.

Stream buffer BMPs are those which directly effect the form a nd func- tion of the stream buffer. Stormwate r BMPs are those which h elp counteract the forces of st ormwater runoff. There a re many exce ll ent handbooks and a lot of tec hnical assi stan ce on the selection, p erformance and install ation of BMPs. The following provide so m e basic prin - ciples to co n si d e r in devising yo ur strat - egy, but yo u will still need to co n sult technical manuals, agency staff and con- sultants when choosin g or requiring spe- cific approaches. When d ealing with high stormwater flows, consider that buffers generall y have the capacity to treat only ten p er - cent of total runoff since m ost stormwa- ter runoff flow s directly into stream s through stormwater pipes and smaller tributaries . Stormwater runoff impacts streams by causing bank erosion as well as carrying sediment from overland runoff into str eams. Stormwater from streets, parking lots and rooftops, als o rai ses stream t emperature and ca rries harmful stree t p ollutants , s u ch as oil, into streams. Selecting BMPs There are two approaches to applying a BMP. It may b e performance-based , which assumes that a BMP wi ll remove a certain percentage of runoff, sedi m e nt, and so on. O r it may b e outcome-based, where m easurements en sure that the impact o n a stream o r wetland meets pre-determined sta ndards . An outcome-based measure is more likel y to en sure that the BMP is having the intended effect. However, most local gov- ernment and state age nci es don't h ave resources to co nduct the necessary moni - toring to ensure standards are being m et. So m e stat es sp ecify whi ch BMPs can b e u sed to meet program goals , based o n th e assumption that certain BMPs have been --- Once these issues have been identified, co n sult the local government's eng in ee r - ing department or an engineering firm to determine the most appropriate BMPs for your approach .

Stormwater manage- ment requires a comprehensive approach, which includes trapping and filtering stormwater before it reaches the stream in stormwater ponds, biofilters, grassed swales and other stormwater measures. Once stormwater problems are mitigat- ed, in-stream techniques can help to repair prior damage. These techniques require careful application of engineer- ing principles by consulting with a qual - ified geomorphologist and hydrologist. You also need to get all applicable per- mits from state and federal agencies for work in the stream channel or on its banks. These in-stream BMPs help enhance and protect any buffers that have been put in place. We have li sted numerous bioengineering and stru ctural techniques that are used for str eam bank restoration projects, such as fascines, live cribwalls, or riprap. Bioengineering combines biological (liv e plants) and engineering (structural) methods to provide a stream bank stabi - lization method that p erforms natural stream functi on s without habitat d estruction. These techniques have existed for hundreds of years, but were abandoned with the advent of concrete and large machines, which were u sed to channelize and pave streams . In the past twenty years, bioengineering methods have been gaining in popularity in the United States as a way to repair degraded streams, protect land structures ••llhods Landscaping Preserving existing vegetation Stormwater management agreements Clearing limits Prevent eros ion on temporary an d private roads Terraces Diversions Cover crop pi ng Conservation tillage Contour plowing Crop rotation close to streams such as power lines, and restore stream habitat. These BMPs are best used for direct stream restoration projects over seen by an engineer or geo- morphologist who is familiar with ripari - an evaluation and desig n . There are sev- eral u sefu l reso urces covering these meth - ods in Appendix A. They are listed here to provide the reader with a basic famil- iarity of some of the m ethods available: • Brush layering : Live branch cuttin gs, crisscrossed on trenches between s u c- cessive benches of soi l . • Gabions: A wire rectangular basket filled with rocks and anchored against the stream bank to prevent erosion . Gabions are best covered with soi l and grasses or shrubs to avoid harm to wildlife and improve aesthetics . • Live cribwalls: A hollow, structural wall used for bank and slope stabiliza- tion formed by mutually perpendicu- lar and interlocking members (usually timber), into which liv e cuttings are inserted, along with soi l to stabi lize roots. • Live f ascines: Sausage-like bundles of riparian woody plant cuttings used to stabil ize stream banks, generally planted and staked into trenches par- allel to the stream. • Live staking: Cuttings , u sually at least one inch in diameter, from living trees that are inserted into str eam banks to stabi li ze the slope. • Riprap: Stones of varying sizes that are u sed to stabilize the stream bank. They can be used at the toe of the bank in conjunction with methods mentioned above. Riprap should be hand -placed (not dumped ) and stones should be somewhat larger than those generally transported by a two-year storm flow. Stormwater BMPs Other types of BMPs can help address the effects of stormwater runoff These incl ude such practices and structures as stormwater management ponds, co n - stru cted wetlands, grassed swales and public education programs, all of which can help retard and filter runoff prior to it reaching the buffer. There are two different types of stormwater management practices. The first uses preventive measures -source control and nonstructural practices -to mitigate stormwater pollution. The sec- ond uses control measures -known as treatment practices -such as bioreten- tion basins, sand filters and wet ponds. As stated previously, control measures should be specified within accompany- ing design manuals to ensure that the scie nc e behind the BMP is up-to -date. P reventive Measures Preventive measures, sometimes cal led source controls , are management tech- niques that reduce the exposure of m ate- rials to stormwater, thus limiting the General Conshucllon Aartculbn x x x x x x x x x x x x A Stream Corridor Protection Strategy for Local Governments 29 am ount of p ollu tan t s and sed iment t h at ar e p ic k ed up durin g a st o rm .

For exampl e, if a goal of the strategy is to protect fish habitat, an evaluation of exist - ing fis h habitat and fish species should be conducted before the strategy begins, before goals are establi sh ed for enhancin g or increasing that habitat, and before a timetable is drawn up for monjtoring fish and their habitats . Targets for habitat protection or improvement should be set , along with benchmarks to evaluate s uc- cess along the way and contingency p lans if those goals are not met. Components of an Effective Monitoring Plan There are a number of specific compo- n ents fo r monitoring the success of the projects or objectives of your stream protection strategy. These are: • Specific management objectives for the project or program. • Monitoring methods tied to achieving management objectives; for exa mpl e, conducting in-stream biologi ca l and chemical testing for projects intended to improve stream health . • A clear methodology and schedule for conducting m onitoring of the si te (or sample sites). • A reporting mechanism: Who con - ducts the monitoring, and who receives and evaluates r esults? • Milestones for achieving project objec- tives. • A process to reassess or repair failing projects. Monitoring BMPs If specific management practices, s u ch as forested buffers, are installed as part I I Monitoring and Maintenance of a stream protection strategy, then staff shou ld monitor the performance of the BMP to ensure it is working . For exam - ple , if trees were planted to restore a for - est buffer , the survival rate shoul d be measured at least ann uall y, and prefer- ably at least biannuall y -say in spring and fal l. Plans and funds should be available to replace lost trees or do site repair work. Fifty percent of trees and shrubs should s urvive lo n ger than two years . If the government is funding a private site, it may be necessary to provide funds or technical assistance for monitoring and reporting. For example, if a stream restoration project is protecting one side of the stream while causing the other bank to erode, new en gineering and installation s may be n eeded. O r , if the project is designed to fence cattle from a stream, so m e annual docum entation should be supplied that fences are intact and the project is o n -going. Depending on the scope of the project, inspection s and enforcement may b e needed to e n sure that project goals are met. Using intermediate indicators and milestones One approach to monitoring is to use intermediate indicators and milestones to measure a strategy's success. If an indicator species is used , it should be one that can be clearly linked to the management strategy. A sample goal for a river habitat restoration plan might use the presence of brook trout as an indica- tor of success and the number of addi- tion al trout spawning in the creek by Spring 2 004 as a milestone for its achievement. As an example of including indicators and milestones in your strategy, consider the following. The goal of the strategy is to improve water quality to Muddy Creek by 2 005 . A specific objective is to "Restore 200 miles of riparian forest buffer to Muddy Creek by 2002." One of the milestones of the strategy is an X increase in the number of brook trout per mile by Spring 2004. Indicators of success are water quality and in -stream habitat, which are monitored to ensure that they are maintained or increased. If benchmark indicators are not achieved , there should be predetermined remedial actions to ensure that the goa ls are m et in the future. BMP Maintenance When working with private landowners, it's important to include a maintenance schedul e along with "allowed and restricted activities." For instance, if grant funds have been provided by a government entity for planting trees or if tax reductions (use-value taxation) have been provided , it's reasonable to require that the site be maintained. In the case of Licking Hole Creek in Albemarle County, Virgin ia , the landowner did allow a steam buffer and bioengineering project to be installed properly. However, he had previously had a lawn A Stream Corridor Protection Strategy for Local Governments 31 s~mpie Steps for p~~ririirig l.f01.tr str~tegl.f 1. Name of the project Happy Trout Watershed. 2.

Establish a specific objective Objective A. of this project is as follows: To restore 100-feet-wide forested buffers on both sides of the stream with native species of trees and shrubs on twenty linear stream miles. 4. Establish specific tasks to achieve objective • Implement riparian easement and planting program with county landowners. • Purchase lands from those unwilling to donate easements. • Assess and plant buffers as needed, to improve pollution removal and wildlife habitat. S. Establish an implementation and monitoring plan • Monitoring Baseline: Measure and establish a current baseline of trees and shrubs for each project area. Devise a plan to restore trees and shrubs (with review and approval by project sponsors, as required). • Implementation: Install planting project and record location, number and species of installed trees and shrubs. • Ongoing monitoring: Revisit site at six-month intervals and record survival rates (this can be done for the entire area or for predetermined sample plots intended to represent the entire plot). • Maintenance plan: For losses greater than 60 precent, repair and replant as needed, according to buffer maintenance manual. 6. Consider providing funds or contingency plans to provide repair or reinstallation if the project is found to be unsuccessful. Establish a project endpoint, as appropriate. For example, will five years of successful buffer revegetation be considered a success, or is the project to be inspected in perpetuity? down to th e stream 's edge and h e co n sis- tently mowed the yo ung trees after install ation . Fortunately, this did not kill the trees, but it did preve nt growth of suffici ent canopy to shad e the stream. A m ai nte nan ce agree m ent, which restricted mowing , co uld have prevented this probl e m . O t h er Main tenance Methods Ther e are seve r al other techniques you ca n empl oy to monitor and maintai n a stream. Posting a bond You can post a bond to e n s ure that the goals of the proj ect a r e m et . For exam - ple, the bond may requi re that a certain number or percentage of trees su rv iv e t o a specified yea r and that, if not, remedi - atio n or replanting ca n b e required of the d eve loper or r esponsib le landowner. Pre -assessment and post-assessment For goals related to wat er quality, the quality of water in the stream should be assessed b efo re and after th e project. There are many methods that can be employed to do this. It may take ye ars for a sever ely impaired waters hed to recove r. Con sult with state environm ental moni - toring agencies to find out what data t h ey have for yo ur stream and whether they are willing t o incl ud e monitorin g of yo ur strea m in their regu lar inventory.

Clearly recorded buffer boundaries Strea m buffers can face tremendou s pres- sure fr om en croachment and disturban ce . These disturbances include tree removal , co nv ersion to lawns , fi ll ing and dumping. Often , these practices happen becau se buffer boundaries are invisible to local landowners, contractors an d local govern - 32 Chapter Six: Mo nitoring and Maintenance m ent officia ls. This is due in great part to the lack of recorded boundaries on official maps a nd the la ck of landowners who are educated about the stru cture and function of stream buffer s. Designers and planners are often to blame for this oversigh t . Frequen tly, during the creation of site plans, buffers are d elin eated on fi n a l or conceptual plans but n ot on construction docu- ments. This greatly increases the ri sk that contractors wi ll en croach upon or disturb b u ffers in the co urse of their work. Local governments a lso often fail to record buffer boundaries on official maps. Without this information, local governments cannot look systemicall y at the current system of buffers or eas il y eva lu ate the impact of future develop - ments on stream systems. Within an ordina n ce , lang u age shou ld be incl uded that specifies how buffers are recorded on a ll plats. This information should inc lude the dimensions of the buffer. T o address problems ca u se d by co ntrac - tors, maintenance crews and the public in gen eral, some localities a re n ow using sig n s in the fie ld to mark off buffers . The sign lets people know that it is an e nvi - ronmentally se n sitive a rea and gives a contact fo r more information . In Virginia, Albemarle Coun ty 's Department of Engineering and Public Works used funding from the state 's Chesapeake Bay Lice ns e Plate Grant to help support a Buffer Sign Program. Virginia's Chest erfi eld and Henrico Counties use R eso urce Protection Area sign age to id entify buffer protection areas. Evaluation and Enforcement Although riparian buffers are u sually on private property, it 's still recommended that ordinances specify proce dures for esta bli shi n g protective covenants, such as a co n servation easement where a landowner does not wish to take respons i- bility for the maintenance of the buffer. This is particularly true in the case of sub - divisio n s , whe re a cluster development might create a "no-man's-land ," where management issues are not clear once the lots are sold . It 's also important that all land lease agreeme nts co ntai n information regarding the location of and management requirements for the buffer.

These stream s feed Baltimore City's three drinking water r eservoirs , which supply over 1.8 mill ion ci t izens in th e Baltimore region . To protect their re so urces, the co unty esta blished a n Integrated Waters hed Management Program (IWMP). This program focuses effo rts on seven key IWMP elem ents: land preservation and growt h management; res ource protec ti on (regu lations ); envi - ronmental resto rati on; facility mainte- nan ce; water quality monitoring; wat er - sh ed managem ent planning and ecosys- te m research ; and ed ucation and ci tizen partici pation . Stream buffers play a key part in th e county's res toration projects and regulatory efforts. The IWMP has evolv ed to provide a framework for inte- grating watershed scales, agency func- tions and federal /st ate mandates. Process W etland and stormwat er issues in the co unty in the mid -1980s d em onstrated the n eed fo r a regulatory approach to stream protection . In 1988, the County 's Water Quality Steering Committee made recommendations for a regulatory pro- gram . In 1989 , staff crea ted an Exec utive O rd e r which was developed into fo rmal regulations under the Regulations for the Protection of Water Quality, Streams, Wetlands and Floodplains in January 1991. The development industry was invo lved in the negotiation s and this helped to gain County Counci l approval. The goal of the regulations is to protect the county's riparian and aq u atic ecosys- tems, thereby protecting water quality. These regulations help maintain stream health because they apply to all land development in the county (specificall y land subdivision, land clearing fo r d evel - opment and co n struction ) and agri cul - ture, forestry an d mining. The regula- tions apply t o : • all n ew developments • timber harvesting activities that are n ot in an approved Fo rest Management Plan • all land s that are ca u si ng , or co n - tribute to , stream pollution, erosion and sedimentatio n , or th e degradation of stream habitats (unless the land is agricultural and has an approve d Soil and Water Con se rvation Plan) The county's reg ulations call for specific design standards fo r forested buffer s and building set-backs. Forested buffers are defined as: " ... a forested strip of la nd extending a long both sides of a stream and its a dja- cent wetlands, flo odp lain, and slopes. Th e forest buffer width shall be adjusted to include contiguous, sensitive areas, suc h as steep slop es or erodible soi ls, where devel- op m ent or disturbance may adversely affect water quality, streams, wet lands, or other water bodies. This adjustment shall be accomplished by eva luating the paten- A Stream Co rridor Protec tio n Strategy for Local Governments 35 tial of a si te for impac ts that result from runoff, soi l erosion, and sediment tran s- port." Sec. 14-341 Buffer width is determined by strea m classification and fo rmu las fo r evaluat- ing stee p slopes and erodible soils. The minimum buffer wi dth is between 75 and 100 fe et on each sid e of the channel. The default width for each stream is set based on its water use classification. Buffers are d escribed b y 'm etes and bounds' on recorded p lats and restricti ve use covenants are recorded in the official land records . In addi tion to requiring the demarcation of ri parian buffers on d evelopment pl ans, the regulations also require the manage- ment of ex istin g buffers by restricting activities su ch as soil or vegetation distur- bance, filling, dumping , u sing motorized vehicles and pesticide u sage (except for the sprayin g of noxious weeds ). When asked about the advice he wo uld give to other lo calities, Don O uten of the Department of Environmental Protection and Resource Managem ent said that two key ele m ents of the project we re : • Looking at functions that streams pro- vide and u sing buffers as a tool to pro- tect those fun ctions. • Working closely with the development community to cr eate the program and ensuring that the stan dard ization , convenience and certainty that d evel - oper s r equire we r e included .

P rocess To address the need for education on water quality and stream buffer preser- vation , the DEPRM has created a multi - media environmental edu cation program call ed "L et 's Be Partners ... Water Pollution: What We Can Do to Reduce and Prevent It." It is offered free of charge to schools and citizen community gr oups throughout the county. The program is tailored specifically to Baltimore County and frames a water- shed approach for local str eam aware- n ess. The goa ls of the program are to address the ca u ses of water quality degradation in Baltimore County, to outlin e the current efforts that are b ei ng made to address pollution and to ex plain effo rts that citizen and business groups can undertake to address pollution in lo cal streams, drinking water reservoirs an d the Chesapeake Bay. To m aximize the program 's audie n ce, the program was designed to b e adapt- a bl e for a variety of ages, abilities, inte r - ests and time constraints . It also is gea r ed to cit ize n reduction of nutrie nt, toxic, and sediment pollution that reach- es local streams, drinking water reser - voi r s and the Chesapeake Bay via num- ber of reaso nable , cost-saving ideas that anyon e can employ. The program addresses the followi n g topics: • Water Pollution: wh at it is, and how it enters the waterway (point and non - point so u rces). • Effects of pollution: loss of valuable resources. • What specifically can b e done: • by government ag e ncies at all leve ls ? • b y individual citizen s, families and school groups? • b y businesses, neighborhoods, and communities? • Where to get further information .

It has a pop - ulation of approximately 54 ,000. Parties and Roles An Environmental Guidelines Committee was created to d evelop the city's environmental standards. The committee consisted of staff and citizens from a variety of city departments and committees, as well as represe ntatives from the neighboring city of Rockvi ll e, regional governmental agencies, local engineering and development firms and local non -profits. City staff perform ed most of the research and development for the environmental standards. Other regional organizations provided technical expertise and guid- ance during the d evelo pment process . Such organ izations incl u de the Maryland-ati onal Capital Park and Planning Commission, the Forest and Wetland Conservation Association , Environmental Quality Reso urces, Montgomery County Department of Environmental Protection , the City of Rockville, Quadrangle Deve lopment Committee, Rodge r s & Associates, th e Metropolitan Washington Council of Governments, the Montgomery So il Conservation District and the Izaak Walton League of America. Trigger I ss u es In 1994, city planning staff were stru ck by the fact that, although the city had many environm ental ordinances for issues s uch as fo rest con servation, sedi - m ent and e ro sio n co ntrol , stormwater m an agem ent and floodplain manage- m ent, a resid ential development propos- al that met these deve lopment st andards still threatened an impaired stream. In response to citizen co ncern s over thi s issue, the C ity Co uncil directed the city Planning Department to create en viron - m ental guidel in es fo r d eve lopments . P r o cess In 1994, th e cit y start ed a series of bi week ly m eetings to create environ - mental guidelines. At the table were local d eveloper s, Planning Com mi ss ion re presentatives, City Council members , environm ental con sultants, regional and county environm ental professio nals and city staff. Using other authorities' ordinances as a guideline During the m ee tings, environmental guidelines that had been deve loped by the surrounding jurisdiction of Montgomery County were u se d as a mod e l. It was felt that these guidelines were co mprehe n sive and that they wou ld help d eve lopers who operated in both Montgomery C o unty and the City of Gaithersburg. After five months, t he committee is su ed the fir st draft of the C ity of Gaithersburg Environmental Guidelines. The docu - ment was di vi d ed into two sections: • Natural R eso urces Inventory (N RI) • Standard s for Development Natural Resource Inventory Environmental information about a pro- posed d evelo pme nt si te is fir st gathered during the Natural Resources Inventory (NRI ). The RI is a co mplete analysis of exist ing natural reso urces and includes a map a nd a submitted narra - tive r eport describing: • stream s and fl ood plains • strea m b u ffe rs • topography • soi ls •wetlands • forests a nd trees • dan ger r eac h / dam break analysis • threatened and endangered specie s • species in n eed of conservation • ex isting wildlife • s p ecia l protec ti on areas • cultural resources • stream quality • n oise pollution • sig nificant views and vistas The environmental standards are applied in the site plan review process, in order to protect the enviro nmental features identified in the N RI. They are also considered in the formulation of staff reco mme ndations to the Planning Commissio n . Standards for Development The stand ard s for development r eg u la - tio n is based on the principles of com- prehensive watershed managem ent and protection and include the following managem ent strategies: • The encouragement of judicious use of land to limit i mpe rvious surfaces and m aintai n wetlands, floodplains , seeps, b ogs, and so on, in thei r natu ral condition. • The establishment of protected slope a reas that address slo p e gradient, soil erodability and proximity to stream channels. • The u se of strea m buffers, the widths of which d e p end on the stream 's state- use d esig natio n , the gradient of adja- ce nt s lopes , and the prese nce of erodi - ble soils. • New o r creati ve t echniques that can be d e mon strated to accomplish the same goals as the s pecific standards can b e con sid ered, in conj uncti on with waiv- er r eques t s . A Strea m Corridor Protection Strategy for Local Governments 31 • The protection of both uplan d and ripari an forest reso urces . • The recog n ition and protection of the ecological significance and functions of headwater areas. • Baseline monitoring to understand and protect the city's stream systems. • The provision of healthy forest and tree cover for the p u rpose of mai n tain - ing water quality, preserving wi ldlife habitat, preventing erosion, mitigating air poll ution , controlli ng water tem- perature and enhancing community amenities in an urban izing environ - ment. • Adherence to the state's erosion and sedimen t control standards. • The provision for stor mwater man - agement structures, storm drainage systems and other facilities in a man- ner that respects the in tegrity and t h e natural eq u ilibrium of stream systems. • The in corporation of BMPs into land disturbance activities. Environmental standards The 1995 E n vironmental Standards fo r Regulation was incorpor ated into the site plan review p rocess an d were relatively successfu l. The standards have been a beneficial too l for iden tifying problems and opport u nities during the deve lop- ment process. They offer a clear and com - prehensive m ethod fo r d evelopers an d staff to eval u ate important natural fea- t ures of a site and the poten tial impact s of development. In addition , the stand ard s incorporate mitigation m easures, in order to create flex ibility and b alance growth with natu ral resource protection . However , since the stan dards were n ot adopted as r egu lations, t h ey did not h ave the weight of law and we re not fu ll y enforceabl e . In addition , althou gh t h e original stan dards had an implementa- tion section, a waiver p rocess was not clearly iden ti fied and t h erefore waivers were granted on an ad h oc basis. In 1998, an independent consultant reviewed t h e city's enviro n mental stan- dards an d r ecommended they be written as a regulatio n , to allow fo r enforcemen t. Staff and the Environmen tal Affairs Committee began a comprehensive 38 Chap ter Seven: Case Studies review of the Environmental Standard s and proposed several changes to stren gth - en t he city's environmental protectio n measures . In addition, the process involved an outside review by the Maryland National Capital Park an d P lanning Commission, the City of Rockville , the City of Bowie , the U n ited States Humane Society, the Izaak Walton League and several engineering firms. The Environmental Standards for Development were rewritten as a regul a- tion and were adopted in ovember 2001. They incorporate a comprehensive waiver process with a detailed description of instances for when a waiver is requ ired , specific criteria that m u st be fulfilled for a waiver to be granted and compensation requirements for gran ted waivers.

O n e third of Richmond's metropolitan area is located in the cou n ty. The co unty's Assess m e nt and Watershed Management Program began with a co u ntywid e stream q u a li ty assessment . The assessment led to t he establishment of a stormwater quality ge n eral fund and a meth od for prioritiz- ing stream restoration projects in Henrico County, Virgi n ia . Trigger Issue s I n 1993, Henrico County decided to apply the Chesapeake Bay Preservation Area (C BPA) Designation and Management Regulations to the enti re county to satisfy PDES requirements. After worki n g with Bay Act criteria fo r a number of years, many different and varied best management practices (BMPs) began to be uti lized in deve lop- ment projects. Some of the BMPs were found to be more effective than were others. In fact, an early study showed that eighty nine percent of pollutant removal from the streams was achieved by j ust 65 percent of the BMPs . This led the county to conduct a review of the 35 percent of BMPs that were ineffective. These were primarily locat- ed in subdivisions and redevelopment sites and were some of the most costly to instal l. The county concluded that a new program was needed to better use the resources spent on water quality. Process To he l p maximize resources for water quality enhancement and to satisfy regu - latory r equirements mandated by the CBPA, Henrico County developed its Stream Assessment/Watershed Management Program in two phases: • Phase One d evelo ped protocols for stream assessment and implemented them on two pilot watersheds. • Phase Two entailed a county-wide stream assessment. The countywide assessment was target- ed at streams with drainage areas greater than 100 acres. A total of 440 stream miles were assessed -a job that took eig ht two -person teams five weeks to complete in fall 2000. In addition s u r- veyi n g habitat, each team took an inven - tory of the uti lity lines, pipe discharge, erosion problems, channeli n g and so on . Digital photos of these were then sites and data we re then added to the co u nty GIS system. Management area s The assessment efforts resulted in the designation of specific management areas which allow the county to target variou s stormwater man agement meas- ures for different development activities. One su ch measure was the establish- ment of a county stream restoration fund, which is funded by development fees levied on certain management areas. Identifying areas in need of restoration Additionally, the assessment resulted in a countywide identification of more than 900 stream segments in need of restora - tion. T o help prioritize restoration efforts, the impaired segments were ra n ked using criteria such as develop- ment within the watershed, the condi- tion of upstream and d ownstream seg- ments and overall stream condition . As in mos t counties, o n e of the stu m- bling b locks to restoration efforts is that most cr itical stream segments identified by the program fall on private land . Restoration efforts we re possible on ly through cooperation between the co u nty and land owners. It's hoped that funds collected through development fees will help the cou n ty resto re these streams.

Its waters flow in to the Potomac Rive r , which is a major tribu tary of the Chesapeake Bay. The co u nty was fo u nded in 1742. Hist or ically, the rive r was used by the Dagu e Indians a nd has an extensive history of u se by ea rl y set- t lers fo r milli n g grai n a n d l umber. The Difficul t R u n project is tar geted throu gh out fo u rteen m il es of the u r b an stream's watershed. T rigg er I ssu es Like m an y co u nties, Fai rfax is under in creasi n g d evelopm ent pressu re. The co unty's popu lation is p rojected to increase by 216,510 over t h e next twen ty years. T h is growth has led to a host of water quality problems. One such case was Difficu lt Run, whi ch began to show symptom s of stress from nonpoint so u rce runoff cau sed by an increase in impervi- ous surfaces su ch as roads, roofs, side- walks an d parking lots. T hese symptom s included increased str eam water tempera- tures and severely eroded stream banks. Process The Difficul t Run Ri p arian Project was created as a means, not onl y to address the stream's problems, b u t also to raise awareness within the co un ty abo u t the importance of u rban ri par ian buffers and t h eir conse rvation. Since its inception , the project has developed into a water- shed-wide reforestation effort that fos- ters part n erships between federal, state and loca l agencies and the citizens of Fairfax County. The project's imple- mentation includes: • identification of target sites • reforestation of the chosen areas • a watershed-wide ed u cation and o ut- reach program To aid in site identification , a workgroup including the Virginia Department of Forestry, the Metropolitan Washington Council of Governmen ts, Fairfax County Park Authority and the Soi l and Water Conservation District deve loped a protocol for evaluating riparian buffers. The protocol developed a scor - ing system based on fifteen land -u se and environmental characteristics that are used to prioritize refo restation and restoration needs . Identification and reforestation efforts began along the Difficult Run mainstem and included planting 15,000 tree a n d shrub seedlings on 140 acres. The proj - ect has since expanded to include Difficult Run's tribu taries. Community education Edu cation effort s incl u ded a Water Quality Tips mailing t hat was sent to civic and homeowner association presi- dents. The list was for mul ated in response to a suggestion presented at the Diffic ul t R un Roundtabl e Meeting.

These measures include the pro- tection of an in tegrated stream corridor system and the creation of a River and Stream Corridor Overlay District. Trigge r Issue s Lou doun County is the home of D u lles International Airport. Since the 1960s, the population has increased from 20,000 to 185 ,000, ca u sing tremendous pressures on the county's natural resources and infrastructure. Loudoun County's tremendous growth rate mandated that earlier planning strate- gies undergo a critical reevaluation. Former policies were no match for the market dynamics that were quickly erod- ing the county's rural character. Although the county's (1993) Scenic Creek Val ley Buffer and Floodplain Overlay District ordinances were already in place , planning officials realized that a new comprehen - sive approach was needed if the county's natural resources were to be protected. Process Loudoun Cou nty's new ly approved Revised General Plan outlines a frame- work for comprehensive natu ral reso urce protection by organizing the county's environmental, natural and heritage reso u rces into one related system call ed the Green Infrastructure . T he Green Infrastructure comprises four groups: Group One: Natural Resource Asset s • river and stream corridors • scenic rivers a nd the Potomac River • surface and ground water resources • geo logic and soil resources • forests , trees and vegetation • p lant and wi ldlife habitats Grou p Two: Heritage Reso u rce Assets • historic and archaeological resources • scen ic areas and corridors Grou p Three: Open Space Assets • greenways and trails • parks and recreation • p u b lic school sites • open space easements Group Four: Complementary Elemen ts • air quality • lighting • the night sky A Stream Co rridor P rotec tio n Strategy fo r Local Governments 39 Identifying environmental infrastructure The aim of the Revised General Plan is to look at the Green Infrastructure first and then appl y conservation d esign to all development and redevelopment in the co unty. This is accom pli shed, in part, by guiding d evelopers to first identify the environmental infrastru cture of a piece of land before outlining where struct ures , roads, and lot lines wi ll b e located. Den sity credit is provi ded for all G ree n Infrastructure elements , so those areas of a site that are n ot identified as part of the co un ty's G r een Infrastructure can be developed at full density, equal to the den- sity potential of the gross area of the site. River and stream corridors The P lan clearly establi sh es river and stream co rridors as the largest ele m ent of the County's Green Infrastruct ure . The plan targets rivers and strea m s that drain areas of 100 acres o r more a nd have corri dors that i nclud e the fo ll owi n g compon ents: • Associated 100-year fl oodplain s and adjacent steep slopes: a SO-foot pro- tective management bu ffer is estab - lished to protect the corridor, the floodplain and adjacent steep slopes. A 100-foot m inimum stream buffer protects the streams when the 100- year floodplains, adjacent steep s lope areas and the SO-foo t Management Buffer are not great er than the mini - mum str eam buffer. • Riparian forests . • Wetlands. • Historic, cultural and archaeological reso urces that fall w ithin the co rridor. River and Stream Corridor Overlay District To protect these river and steam corri- dors, the county plans on revising its zoning and subdivision ordinances and facility standards manual, and adopting a River and Stream Corridor Overl ay District (R SCOD). Density development transfer L oudo un County also contains two sce- nic rivers, a s d esignated b y the Scen ic Rivers Program of Virginia . These are Catoctin C r ee k and Goose Creek , both of whic h flow into the Potomac River. These two cree ks and the Potomac River will be protected by a 300 -foot no-build 40 Chapter Seven: Case Studies buffer , or the RSCOD, whichever is greater. The co un ty will also protect its water supply reservoirs with a 300-foot no-build buffer or the RSCOD , whichever is greater. The plan allows for a density development transfer from the no-build buffer. To en sure the protec- tio n , conservat ion and restoration of an integrated stream system , the plan also looks to the source of its streams and call s fo r the protection of headwaters originating in the coun ty's mountains .

T rigger I ss u es Beginning in the 1970s, Albemarle Coun ty protected its drink ing wate r rese rvoirs, introduced stormwater rete n - ti o n provisio n s, implem ented state-m an - dated erosion control m easu r es and cre- ated a stream buffer program based on the Chesapeake Bay Preservation Act . As a r es ult, there were a co n fu sing number of standards and o rdinances that d esign - er s, developers and co unty staff had t o r eco n cile. In addition , water quality treatment practices we re not applied uni formly to development sites an d innovative stormwater practices we re not being util ized . P rocess To help strean1line its water q u ality man- age m ent program, the county embark ed upon the task of creating a single, com- prehensive ordinance that would: • Stream lin e the process of development review for water-related items. • Promote the use of a wider range of t r adition a l a nd innovative BMPs a nd stormwater techniques. • Provide a template fo r regional sto rmwater management, involving n eighbori n g jurisd ictions . • Provide a framework for complying with NPDES regu lations and develop - ing a watershed-based approach to stormwater management. Befor e it cou ld develop a new ordinance , it was critica l for the county to have an in -d epth understanding of the need for improved water management. To meet this need , studies where undertaken , which showed that urban streams car - ried high pollutant loads after storm events. These results indicated a n ee d to update and improve current water quali- ty strategies. Focus group The study also provided the county with baseline data, against which future improvements and changes could be measured. In 1994, the county's Water Reso urces Committee decided to fo rm a foc u s group to assist in the development of a new ordinance. The gro up consisted of developers, designers, environmen tal gro ups , governm ent agency staff a nd other local decision-makers. The group met for almost two years and assisted sig nificantly with efforts to develop a broad-based consensu s for improving storm water management. Public review The first draft ordinance was presented fo r public review and comment and was reviewed by co unty legal staff. umerous subseq u ent drafts were creat ed to inte- grated reviewers' comments. It was finally presented and adopted by the Board of Superv isors in early 1998. Design manual Sin ce adoption of the ordinance, all n ew development plans have incorporated stormwater BMPs, including stream buffers. To help designers understand a nd choose different BMPs and perform the necessary calculation s, a Design Manual was cr eated. The co un ty is now worki n g on a series of stormwater master plans that will adopt a wat e rshed-based approac h . In addi- tion to on-site BMPs, the program will include stream buffer and stream bank restoration, regional BMPs, and ed uca- tion and outreach. These measures wi ll be a co mponent of co mpl ying with n ew PDES Phase II Regu lati ons.

Trigger I ssues The effo rt to create a r egio n al ap proach to watershed management was not new. Other cooperative initiatives in the area date back to the 1960s, '70s and '80s. In the mid-90s, however, the Hampton Roads Planning District Commission began to see an increase in pressure cau sed by the many e nvironmental, economic and r egu latory interests in the watershed. Process To help align these disparate interests, the Southern Watershed Management Program (S WAMP) was created . The goal of the project is to develop a cooper ative local govern m ent approach for the manage - ment and protection of th e Southern Watershed Area, with the intent of b al - ancing environmental resources with eco- nomic development opportunities. Six-phased plan The SWAMP project has been organ - ized on a yearly basis according to a six - phased plan . The first phase developed a framework for the cities of Chesap eake and Virginia Beach to work together on watershed management issues . This led to the creation of a Local Governm e nt Advisory Committee, which consisted of technical reso urce p ersonnel from each locality and a repr esentative from the Virgi nia Dare Soil and Water Conservation District. Phase Two ta sks incl uded the comple- tion of a survey of age n cies workin g in the So uthern Watershed Area and the creation of a Water Q uality Task Fo r ce (WQTF). The WQTF was charged with analyzin g existing water quality data, eva lu ating current methods an d procedures u sed to monitor water quali - ty, and making recommendations fo r future actions. In 1996, during Phase Three, the project b ecame eligib le for fu nding as a Spec ial Area Management Plan from the Virginia Coastal Program. These fund s enabled the SWAMP project to continue co ll ect - ing both technical and stakeholder-related data, create an Agency Roundtable and review development co ntrols used by th e cities of Chesapeake and Virginia Beach . During P h ase Four, t he partnership con- tinued to work on the programs estab - lis hed in Phase Three, s uch as wate r qual- ity data analysis , BMP research and edu - cation, s u stain able eco n om ic develop - ment initiatives and publi c involvement. Phases Five and Six focused on applying the research done in the first four phases to program initiatives. Two such initia- tives were a mapping project to show options for the area's Mitigation Strategy and its Rural Area Preservation Program . Memorandum of Agreement Today, the m ajo r efforts in SWAMP are focused on developing policy based on the research in earlier phases of the proj - ect. In particular, a Memorandum of Agreement (MOA) has b een completed , which deals with water-u se conflicts on the North Landing River. Project staff are also currently in the process of devel - oping a similar agreement for Back Bay and are developing an MOA that deals with wetland mitigation issues in the Southern Watershed. E ric Walberg, principal planner on the project, suggests that other localities wish- ing to use a sim ilar approac h should start by attempting to build communication and a good working relationship betwee n local, state and federal agen cies involved in land use and m anagement decisions . H e adds that mapping and data collection are also criti cal to the management process.

Trigger Issues The n eed for stream quality data in Penn sylvania is extensive; no one gov- e rnment office can gather all the infor- mation it n ee ds to identify the critical a r eas in its jurisdiction. Data ne eds are es pecially strong after large storms an d for assessing water resources in remote areas. By partnering with local ci tizen groups, government agencies are better equ ipped to effectively manage and pro - tect state water resources. Process The Pennsylvania Department of Environmental Protection (DEP) creat- ed the Citizen Vo lu nteer Monitoring Program (CVMP). This program is geared to help organizations and indi- vid ual s understand water quality iss u es and the techniques needed to collect q u ality data . The goals of the CVMP are: • T o foster stewardship b y giving com- munities the tools they need to meet their ow n goa ls related to water resources . • To give the DEP a better understand- ing of water resources by receiving quality -ass ured data from volunteer s. The CVMP has also created partner- ships with other organizations, includ- ing: • The Volunteer Environmental Monitoring Panel (VEMP) • The Keystone Watershed Ietwork • The Alliance for Aqu atic Resources Mon itoring • The Pennsylvania Organization for Watershed and Rivers • River Network A Stream Corridor Protection Strategy for Local Governments 41 • The Stroud Water Research Center • The Delaware Riverkeeper • The Canaan Valley Institute • The Environmental Alliance for Senior Involvement These partnerships are d esigned to facil- itate the set up of stat ewide networks and databases for monitoring results. The aim of the partnership effort between VEMP and River Ietwork was to create a handbook to help citizens with their monitoring efforts . The hand - book offers citizen gro ups a unique study design process, which supports a choice of monitoring m ethods based on each gro up's goals. Additional services offered by CVMP are: • Training programs for volunteer mon- itors. • A services information clearinghouse for vo lunteer monitors . • Identification of partnership opportu- nities with DEP programs. • An annual, Statewide Snapshot of Water Quality that takes place over ten days during which time groups can send their data to the DEP for inclusion in an annual report .

Donegal Creek is a limestone trout stream located in the northwest corner of the county. The Donegal Restoration project is a partner- ship effort to restore the native trout habitat along a predominantly privately owned local creek using a "demonstra- tion project" approach. 42 Chapter Seven: Case Studies T rigger I ssues Intensive agricultural practices and dairy cattle farming around Donegal Creek caused significant degradation . Though it was formerly a trout stream, native trout had not been seen for over thirty years . Signs of stream degradation included: • stream bank erosion • excessive nutrient levels • lack of native vegetation • a sediment-laden substrate • a wide, shallow channel , formed because of accelerated erosion and resulting sedimentation Process To bring the stream back to health, the Donegal Creek Restoration Project was created. The project's main objective was to restore the creek to a trout stream. However, a majority of lands targeted for restoration were in private ownership. This proved to be a large stumbling block. Many of these landowners were cattle farmers who allowed their cattle unrestricted access to the stream , causing much of the erosion and sedimentation. Demonstration fence Original efforts for stream restoration included the creation of a demonstration buffer protection fence along both sides of a 1000-foot stretch of the creek. It was erected by Donegal Fis h and Conservation members, aided by Conservation District staff. A Conservation District tree sale provid ed money for the construction, and it used volunteer labor and donated materials. The demonstration fe n ce was built on a highly visible spot along the West Branch of the Creek. In 1994, additional funding became available from Trout Un limited and th e Pennsylvania Department of Environmental Protection. Further funds were provided in 1996 by the Environmental Protection Agency, through a Clean Water Act grant. Two-phase project The project had two main phases: • Education of landowners. • Implementation of stream restoration projects. Education To initiate the education portion of the project, staff from the Conservation District visited each of the twenty -three landowners affected by the project. Staff helped to assess land immediately adja - cent to the creek to determine impacts to the stream and to approaches that co uld enhance both the stream and the farm- ers' agricultural practices. Education efforts paid off, as evidenced by the par- ticipation of nineteen of the twenty - three landowners. Implementation The partnership then initiated a number of stream restoration projects, including: • stream bank fencing and cattle crossings • fish enhancement structures • stream bank stabilization • riparian buffer strips The primary approach sought to restore trout to the stream by limiting cattle access. After securing landowners sup- port, fences and trees were installed, along with fish enhancement devices, stabilizing eroded stream banks, and narrowing and deepening the stream to improve flow and reduce stream temper- ature . To help reduce nutrient levels and increase the amount of n ative vegetation, stream buffers were planted along the banks. However, because of the small size of the farms and fie ld s, the buffer width was narrowed to a range of 10-35 feet, instead of the recommended 7 5-100 foot width. The final result was enhancement and protection of 6.7 miles along Donegal Creek. The original goal of reintroduc- i n g native trout was met when the fish successfully spawned in the headwaters!

To receive funds for open space protection and enhancement, municipalities were required to create written plans. This highlighted the need to find methods, other than acquisition, to ach ieve con- servation goals. The co unty's review of its municipali- ties' plans showed that there was signifi- cant interest in protectin g stream corri- dors as important natu ra l features. To protect these natural features, the locali - ties initiall y looked to methods like open space development (also known as con - servation su bdivisions, or cluster devel- opments). These, and oth er, conversa - tion ideas were written u p in county plans, b u t it more was n eeded to ens u re that municipalities could reach their stream corridor protection goals. Process To help the h1unicipalities reach stream protection goals, the co u nty put together a task fo rce to create the Guidebook for Riparian Corridor Protection . The task- force inclu ded represen tatives from t h e atural Reso u rces Con servation Service, the Soil and Water Conservation District, the local natural r esource con- servation organization, municipal offi- cials and representatives of the legal community. The bulk of the guidebook comprised a model overlay ordinance that outlined the central features needed to create a successful loca l stream pro- tection ordi n ance in Pennsylvania. Creating two buffer zones Using the specifications outlined in the USDA publication Riparian Forest Buffers as a resource avoided most of the problems involved in developing a new ordinance. One problem that did arise concerned agricultural lands . Many farms in Montgomery County are small, aver- aging about 100 acres in size, so every acre counts. Regulations mandating extensive buffer widths threatened farm- ers ' ability to earn an adequate profit. In recognition of this , the ordinance outli nes two zones for stream buffers and allows agriculture in the second zone . What is a stream? Review of the guidelines caused different municipalities to confront the problem of defining a "stream ." Some localities used soi l survey information, combined with defined drainage areas, others used U.S. Geological Survey information , and some relied on local knowledge. Since the issue of defining perennial streams can be contentious, the county didn't want the issue to inadvertently restrict stream preservation efforts. Therefore, the mode l ordinance a ll owed municipalities to be flexible in their approach to stream definition and identification. Three-pronged approach In general, the county recommends municipalities follow a three -pronged approach to stream protection: • Acquis ition through fee-simple pur - chase or easement. • Land use controls, such as open space development , transfer of development rights and overlay districts, to protect land proposed for development. • Land stewardship education via wo r k - shops, flyers, and brochures.

The Bay Progran1 part- ners include the states of Maryland, Pennsylvania and Virginia; the District of Colu mbia; the Chesapeake Bay Commiss ion, a tri-state legis lative body; the U.S. Environmental Protection Agency (EPA ), which represents the fed- eral government; and participating citizen advisory gro ups . The second Chesapea ke Bay Agreement , adopted in 1987 , estab - lished a vision for the Bay's restoration. Its goals included proposed reductions of harmful nutri ents . In 1992 the Bay Program moved upstream, with strategies for attacking nutrients at th eir sources in the Bay's tributaries. T he Chesapeake Executive Council -co mposed of the gov- ernors of Maryland , Pennsylvania and Virginia; the mayo! ofWashington , D.C.; the EPA administrator; and the chair of the Chesapeake Bay Commission -sign ed five directives in 1993 that addressed key areas to b e restored. These areas incl ud ed the tributaries, topics, underwater Bay grasses, fish passages and agricultural non - point source poll ution. In 1994 the part- ners outlined initiatives to restore aquatic , riparian and upland habitats, reduce nutri- ents in the Bay's tributaries and reduce topics, emphasizing the preve ntion of pol - lution . On June 28, 2000, th e EC signed Chesapeake 2000 -a co mprehensive and far-reaching Bay agreement that will guide the Bay Program partners through the yea r 50 Appendix B: Federal, R egional and State P rograms 20 10 in thei r co mbined efforts to co ntinue to restore and protect the Chesapeake Bay. C hesa peake 2 000 outlines 93 commitments detaili n g protection and restoration goals critical to the health of the Bay watershed. In pledging to increase riparian forest buffers, preserve additional tracts ofland, restore oyster populations and protect wet- lands, Chesapeake 2000 focuses on improving water quality as the most cri ti - cal element in the overal l protection and restoration of the Bay and its tributaries. The three program goals for the Chesapeake Bay Program's forestry work group are: • To e n sure, to the extent feasible , that all streams a nd shorelines will be pro- tected by a forest ed or other riparian buffer. • To conserve existing forests along all streams and shorelines. • To increase the use of all riparian buffers and restore riparian forests on 2,010 miles of stream and shoreline in the watershed by 2010, targeting efforts where they will b e of greatest value to water quality and living resources .

The program seeks to restore 610 miles of missing or inadequate forest buffers in the state ofVirginia by the year 2 010. Buffers must be at least 3 5 fe et wide from the stream bank, contain at least three different tree or shrub s p ecies or achieve regrowth from natural regenera- tion. Buffers resulting from fencing farm animals out of streams wi ll also be counted towards the fina l 610 mile goal.

Contact The Department of Environm ental Quality at http://state .vipnet.org / dof/rfb/ripar ian /rwg /forms .htm Agricultural Stewardship Program Objectives of the program include edu- cati n g farmers about environmental stewardship , strengthening their stew- ardship practices and identifying real water -quality problems. It wants to help farmers correct the problems in a co m - monsense manner that accommodates both the farmer and the environment through their local Soil and Wate r Conservation Districts to resolv e. The Agricultura l Stewardship Act (ASA) of 1996 gives the farmer an opportunity to correct a water quality problem vo lun- tarily before any enforcement action is taken.

These sec tions are: Section 303(d), which req u ires states to li st all impaired or threatened water bodi es; Section 305(b), which requires states to report state wate r quality infor- mation to Congress; and Section 319, which requires states to d evelop Non point Source Management Programs and report progress to EPA. Section 303(d) lists The Section 303(d) list is a comprehensive public accounting of all impaired or threatened water bodies, regard less of the cause or source of the impairment or threat. An impaired water body is defined as one that does meet water quality stan- dards. Violations might be caused by known or unknown so urces of pollution. A threatened water body is one that cur - rently meets water quality standards but for which existing data show that water quality standards will likel y be exceed ed by the time the next lis t is required to b e submitted to EPA. A Sec tion 303(d) li st of impaired or threatened water bodies must be submitted to EPA by October 1 of every year , beginning in the year 2000. ~ L egislation and Agreements Section JOS(b) Report to Congress Every five yea r s th e EPA transmits to Congress the ational Water Quality Inventory R eport (305(b) Report . This re port is based on individ u al state reports that identify wi d espread water q u a lity problems , and d escribe the va ri- ous programs implemented to restore and protect state waters. Clean Water Act Section 319 In 1987 Congress amended the C lea n Water Act in order to establi sh the Section 319 onpoint Source Management Program. The aim of this program is to help state and local water quality management efforts. Under the Program states receive grant money to support non point source management projects su ch as those offering technical assistance, financia l assistance, educa- tion, training, technology transfer , d emonstration projects , and monitoring . The Total Maximum Daily Load The Total Maximum Daily Load (TMDL) requirement mandates that states set p o llution con trol plans for their impaired rivers and streams. The TMDL requirements of the Clean Water Act allow states to create their own regulatory programs provided that they m ee t fe d eral management and reporting requirements and are approved by the EPA. Once a program is es t a blished, the total allowable leve l for a ny pollutant is based on state stan - dards. UnderTMDL regulations states must submit to EPA a list of impaired waters along with a TMDL of pollutants for each waterway and water b ody on the li st . O n ce listed as a n impaired water, states must also outline how a waterway wi ll meet TMDL standards in the future . States have ten years to bring their water bodies into compliance but are a ll owed an additional five years if need can be proven . The chall enge fo r most states is figuring out how to eco- nomically meet TMDL requirements. TMDLs in Pennsylvan ia, Maryland an d Virginia TMDLs may affect only a segment of a river or an entir e section. For example, the entire Anacostia River Watershed in Washington D.C. is considered 'impaired' and a TMDL must b e co m - pleted and implemented for the entire nver. Pennsylvania In 1997, Pennsylvania's Department of Environmental Protection (DEP) agreed to a twelve-year schedule to develop TMDLs for impaired strean1s listed on the 1996 Clean Water Act Section 303(d) list. To this end, all unassessed streams in Pennsylvania will be assessed by the DEP withi n ten years. During this time, any stream segment that exceeds minimum standard s will then be added to the Section 303(d) li st (wi th a TMDL to follow ). As of 2001, 45,234 miles of 83, 161 total stream miles in Pennsylvania were assessed. A total of 37, 927 stream miles remain to be assessed in ord er to achieve comprehensive coverage, based on the current GIS coverage. Of the 45,234 miles assessed , 8, 193 were found to be impaired or 18.1 percent of the total miles assessed . The two largest so urces of reported impairment are agriculture, with 2,887 miles of reported impair- ment, and abandon ed mine drainage , with 2853 miles reported. Sources of impairment incl ud e agric ulture (34.5 percent), Acid Mine Drainage (34.4 per- cent) and Urban Runoff(l4 .5 percent). During the development phase of a TMDL, DEP will estimate pollution reduction goals t o meet water quality standards on a watershed basis . Local entities will then be responsible for devel - oping an implementation plan to achieve the TMDL goals. After implementation , A Stream Corridor Protection Strategy for L oca l Governments 51 the watershed will be re-surveyed to determine if the stream segment meets the water q u ality standards . As of December 31, 2001, 154 TMDLs (110 from the 1996 303(d) list) have been sub - mitted by DEP and approved by EPA. For more inform ation on Pennsylvania's program see http:/ /www.dep.state.pa. u s/ dep/ deputate/watermgt/wqp/wqs- tandards/ wqstandards.htm Mar y l and C urrently in Maryland, there are approximately 350 so urces of impair- ments for 130 water bodies . Thirty TMDLs hav e been developed and approved by EPA at the printing of this report and twenty more were up for approval in the spring of2002. In the 2002 305(b) r eport, there are 8,768.9 miles of non -tidal rivers and streams. Of those 8,638 were assessed and 2,949.5 miles were found to be impaired for a total of 33.6% of the assessed stream miles. The Maryland Department of the Environment (MOE) has been instru- mental in the coordination b etween EPA and local governments, convening m eet- ings in which municipalities can discuss their concerns and ask questions about the TMDL process. One of the products of thi s partnership has been a document entitled Maryland 's TMDL Development Program and Local Government Participation. For a summary of this document see http:/ /www.mde.state. md .us /tmdl/localgov.htm .

V irginia The Virginia Department of Environmental Quality is responsible for developing TMDLs over a ten-year schedule ending in 201 0 . Virginia has 50,239 miles of rivers and streams. A total of 9, 700 of those stream miles have been assessed and 4, 403 stream miles were found to be impaired or 44 percent of the total mi les assessed. Virginia cur- rently has 665 TMDLs to develop for its impaired waters by 2010 . As of spring 200 2, the EPA has approved TMDL assessments for 29 of those waters . By May 1, 2004 an additional 81 TMDL assessments must be co mpleted . For more information see: http://www.deq . state.va.us/water/303d.html Wild and scenic rivers In 1968 , Congress creat ed the National Wild and Scenic Rivers System. There are four federal agencies charged with protecting and managing the nation's wi ld and sce ni c rivers : • Fish and Wildlife Service • U.S.D.A Forest Service • Bureau of Land Management • ational Park Service Today these agencies work together under the 1995 lnteragency Wild & Sce nic Rivers Coordinating Council Charter. The goal of the Wild and Scenic Rivers Act is to help protect the natural, cultural and historic resources associa- tion with the nation 's rivers . Under the Act, each river has a unique d esignation and management plan . To be eligibl e for inclusion in the syst em rivers must meet certain criteria set forth in Section 2(b ) of the Act. Under this sec- tion, three classifications are stipulated : • Wild rivers: Those rivers or sectio ns of rivers that are free of impound- ments and generally inaccessible except by trail, with watersheds or shoreli n e essentially primitive and waters unpolluted. These represent vestiges of primitive America. • Scenic rivers : Those rivers o r section s or rivers that are free of impound - ments, with shorelines or watersheds sti ll largely primitive and shorelines largely undeveloped, but accessible in places by roads . • Recreational rivers : Those rivers or sections of ri vers that are r eadi ly accessible by road or railroad , that may have some development along their shorelines and that may have undergone some impoundment o r diversion in the past. 58 Appendix C: Legislation and Agreements Regional Agreements C h esa peake B ay Agreement Bay Agreement of 1987 -cal led for a forty percent reduction by 2000 in nutri- ents reaching the main stem of the Bay. 1992 Amendments -committed to r educe nonpoint sources of nitrogen and phosphorous by 40 percent in the Bay's largest tributaries. Chesapeake 2000 -call s for a reassess - ment of progress made to date and a recom mi tment to the origin al goals a nd recognizes additional steps to be taken to ensure that the original goals set up by earlier agreements are met. The major incentive that drives the Chesapeake 2000 agreement is the removal of the Chesapeake Bay from the federa l li st of impaired waters by the year 2010. To do this it call s for: • The reduction of sediments and nutri- ents. • Ambitious recovery goals for oysters and subaquatic vegetation. • A s ustainab le crab catch. • A measurable decrease in the rate of conversion of farms and forests to developed land s • More effective community-based stewardship of the Bay's rivers and subwatersheds. More information about the Chesapea ke 20 00 Agreement and how it affects pro- tection measures and management of water sheds and streams is found in Appendix B, regional programs . State Legislation There are myriad federal, regional, state and local government regulations in place that affect stream protection and restora- tion. Several acts in particular stand out as major state efforts to bring the goals of the Bay Agreement down to the state level: the 1984 Critical Area Criteria Planning Act of Maryland , the 1988 Chesapeake Bay Preservation Act ofVirginia, 1992 Economic Growth , Resource Protection, and Planning Act of Maryland , Maryland's Smart Growth and eighborhood Conservation Act of 1997 and the Rural Legacy Act. Maryland The Chesapeake Bay Critical Area Law (Md. Code Ann.§ 8-1801 et seq.) In 1984 Maryland enacted a series of legislation that targeted the restoration of the Bay's ecosystems. Most signifi- cant of these was the Cri ti cal Area Criteria Planning Act. This act required significant changes in local land use laws for localities bordering the Bay. The act also establi shed the Critical Area Commission, a 27-member panel charged with creating land managemen t programs aimed at decreasing non point so urce pollution. Central to the act were the Critical Area C r iteria, which establis h ed a set of mini- mum standards to be e nacted by the localities, allowing localities some flexi- bility in tailoring the standards to their particular set of circumstances . The law was enacted in 1984 to mini- mize adver se water quality impacts and to protect the Chesapeake Bay. It seeks to protect water quality, conserve valu - ab le habitat and accommodate future growth in the least polluting manner by regulating activities and land use plan- n in g in what are defined as critical areas . These areas include: • the waters of the Bay • the Bay's tidal wetlands and tributar- ies • the area that li es within 1,000 feet of the landward b oundary of state and private waters and wetlands The act es tabl ishes a 100-foot vegetated buffer within the 1,000-foot critical a rea , within which specific activities are pro- hibited. C ritical Areas fall into three cat- ego ri es: • intensely d eveloped areas • limited d evelopment areas • reso urce conservation ar eas Eac h has a density limit and incorporat - ed performan ce crite ria that are directed to protecting water quality. These crite- ria were establi shed b y the Chesap eake Bay Critical Area Commi ssion. Local governments are responsible for devel - oping and implementing their own Critical Area resource protection pro- gr ams, based on the req uirements devel - oped by the C ritical Area Commission . 1991 Planning Ad In Maryland, counties are primarily responsible for local land use planning. Within this context, the Economi c Growth, Resource Protection, and Planning Act was passed in 1992. The Act instructs local governments to adapt their plans to incl ud e a set of established poli- cies that include concentration of develop - ment, protection of sensitive areas, and steward ship of t h e Chesap eake Bay. The "Sen sitive Areas E lement," which is req u ired for all plans, m u st describe how t h e j uri sdiction will prot ect: • streams and stream buffers • 100-year floodplains • endangered species habitats • steep slopes • oth er areas a jurisdiction wa n ts to pro- tect from the ad verse impacts of development Such planning must also conform to the 1984 Critica l Area Criteria Planning Act. Maryland Tributary Strategies In 1995 the Maryland Tributary Team s were formed . They are comprised of fe d - e ral, state, and local governments busi- nesses, citizens, farmers and ed u cator s. The teams ai m to protect the Chesap eake Bay watershed through the implementation of Maryland Tributary Strategies, the primary goa l of which is to ac hi eve a 40 percent nutrient reduc- tion in each of Maryland's ten major watersheds b y 2000. These strategies are now enter ing a phase of review an d revisio n that is targeted for 2002. A Stream Corridor Pro tec tion Strategy for Local Governments 59 A major milestone in the teams' work was passed in July of2000, when the Maryland Chesapeake Bay Partnership Agreement was signed by Governor Glendening and elected officials from Maryland's counties. The Tributary Teams' state and local government rep- resentatives first drafted this agreement. The cou nties agreed to work coopera - tively to restore local watersheds a nd the Chesapeake Bay. They also committed to participate on the Tributary Teams, to help in the developme nt of the revised Tributary Strategies, to address the goals of the C hesapeake 2000 Agreement, to support the deve lopment of Chesapeake Bay Program policies and to pursue funding and other incentives to support local government watershed restoration and protection programs. When the Maryland Chesapeake Bay Partnership Agreement was signed, the Watershed Revitalization Partnership Fund was also started. The fund sup- ports a grant program to be administrat- ed through a partnership of the Maryland Department of Natural Resources (DNR) and the Maryland Department of Transportation (MDT). These funds are targeted to help locally sponsored stream restoration projects. The partnership expan ds on the existing D R greenway, wetlands and stream restoration proj ects that are currently funded by the MDT throu gh the Transportation Equity Act for the 21st Century (TEA 21). Virginia Chesapeake Bay Preservation Ad (Virginia Code§ 10.1-2100etseq.) The Virginia Gen eral Assembly enacted the Chesapeake Bay Preservation Act in 1988 in order to establish a cooperative nonpoint source pollution program between the state and the eighty-four local governments of Tidewater, Virginia. The Bay Act Program is designed to improve water quality in the Chesapeake Bay and its tributaries by requiring wise resource management practices in the use and development of e nvironmentall y sensitive lands . The Chesapeake Bay Local Assistance Board , which was created by the Act, is responsible for promulgating regulations that establish criteria for local Bay Act programs. The Board is a lso charged with ensuring that local comprehensive plans , zoning and subdivision ordi- nances and other land management pro- grams are in compliance with the Bay Act Regulations. The C h esapeake Bay Local Assistance Department provides staff support to the Board in carrying out the requirements of the Bay Act and provides technical and financial assis- tance to localities. Through the Bay Act, localit ies address nonpoint source pollution by identifying and managing identified Chesapeake Bay Preservation Areas. These lands are clas- sified as either Resource Protection Areas (RPAs) or Resource Management Areas (RMAs). RPAs include tidal wetlands and shores , certain non-tidal wetlands and a 100-foot buffer adjacent to these features and along all perennial streams. Because these lands are so sensitive, development is limited to water-depend- ent u ses and redevelopment . RMAs are sensitive lands co ntiguous to RPAs that, if improperly u sed or developed, can sig- nificantly degrade water quality. Development is not limited in RMAs, but must adhere to the eleven perform- ance criteria specified in the regulations. The Bay Act also requires that Tidewater localities address water quali- ty issues through their comprehensive 60 Appendix C: Legislation and Agreements plans. Localities must include informa- tion and policies and implementation strategies regarding physical constraints to development, protection of potable water, shoreline and stream bank ero- sion, public access and redevelopment as specified in the Bay Act Regulations. Water Quality Improvement Ad (Code of Virginia §10.1 -2118). The purpose of the Virginia Water Quality Improvement Act of 1997 (WQIA) is to protect and restore the quality of state waters. Because this is a shared responsibility among state and local governments and individuals, the Water Quality Improvement Fund (WQIF) was created . The purpose of the fund is to provide water quality improvement gr ants to local govern - ments, soil and water conservation dis- tricts and individuals for point and non- point source pollution prevention, reduction and control programs . A primary objective ofWQIF is to fund grants that will reduce the flow of excess nitrogen and phosphorus into the Chesapeake Bay through the implemen- tation of the tributary strategies. Applicants for projects must first submit a grant application. Virginia Tributary Strategies The Virginia Tributary Strategy Program (VTSP) is a multi-agency effort to coordinate water quality management planning. Headed by the Department of Environmental Quality. It operates under the statutory guidance of Virginia's 1996 Tributary Strategy Law (Article 2 of Chapter 5.1) and the 1997 Water Quality Improvement Act (Articles 1-4 of Chapter 2.1 ). The Tributary Strategy Law specifies the content and schedu le for nutrient and sediment reduction plans. The Water Quality Improvement Act establi shed coopera- tive point and nonpoint source pollution control programs and created the Water Quality Improvement Fund (WQIF), which is the primary source of state funds for the nutrient and sediment reduction actions identified in tributary strategies. Under the Chesapeake Bay Agreement, Virginia has developed nutrient reduc- tion strategies for each of Virginia's major Bay tributaries. The VTSP is a voluntary program that provides scien- tific information on water quality issues, such as nutrient and se dim ent loads , to local officials, businesse s, citizen groups and other stakeholders. Stakeholders are guided through a process of developing goals for nutrient and sediment reduc - tions, identifying cost-effecti ve practices for achieving these reduction s , and implementing these practices. Eac h trib- utary strategy plan is design ed to reflect the unique characteri stics of the area. In addition to Virginia's Tributary Strategies, the state Department of Con se rvation and Recreation has organ- ized Watershed Conse rvation roundta- bles for each of Virginia's major water- sheds. Roundtables are comprised of represe ntatives from the D CR, a nd the Soi l and Water Conservation Districts in addition to other state agenci es , local governments, industries, ci tizens and exis ting watershed organi zations. The goal of the round tables is to provi d e a forum for creating watershed-based strategies for water pollution red u ction . Over the next decade, efforts under the VTSP will be focus ed on 'delisting' the Bay and its tidal tributaries from the state's Section 303(d) Impaired Waters List. This initiative stems out of the Chesapeake Bay Program and is designed to integrate this cooperative program with the regu latory TMDL Program under the Clean Water Act . As set forth in the recently signed Chesapeake 2000 Agreement , the Bay Program partners will work together to remove all impairments, partic ularly low levels of dissol ve d oxygen , from Bay waters by the year 201 0 . This initiative includes the dev e lopment of criteria, designated uses and water quality standards that will protec t aquat- ic life in Bay waters based on needs of habitat, food and other requirements. These objectives will be achieved through eve n gr eater reductions of nutri - ents and sediments into Bay tributaries across the entire 64,000 square mile C hesapeake Bay Watershed . Riparian Forest Protection for Waterways Tax Credit This program prov ides a state income tax credit to Virginia landowners whose property abuts a waterway on which timber is harvested , but who refrain from harvesting for a period of fiftee n years . The tax credit is an amount equal t o 2 S p ercent of the value of timber in that portion of the la nd retain ed as a buffer. The Virginia Department of Forestry monitors this program . Inter es ted landowners sho uld co ntact their lo cal forestry office to a ppl y. For more information see http:/ /www.dof. state.va.u s /rtcguide .htm Th e Virgi nia Surface Water Management Area (SWMA ) Act (198 9) al lows for t h e d esignation of a specified m anagem e nt area in which there is a hi story of low flow conditions. For these areas , a co n - se rvation plan is ap proved b y the State Water Control Bo a rd to ensure that there are minimum flows durin g periods of drou ght. Once adopted , a SWMA requires p ermits for any n ew with - drawals more than 300,000 gallon s /month and a s urface water with- drawal certificate t o continuous with- drawal s (g ranted b y the State Water Control Board ).

Exceptional Surf ace Waters Designation As required by the EPA, every stat e must establish a category of s urface water equ ivalent to EPA's Tier 3 Outstanding ational Resources Waters . In Virginia , an Exceptional Waters Category was adopted in 1992 to designate those waterways that have exceptional recreational status or co ntain significant aquatic communities and are located in an exce ptio nal env iro nmental se tting. Criteria, n omi n ation and desig- nation processes , and restricti on s for this desig n ation can be found at http://www.deq .state .va.us /wqs/ T 3guid .html. C urrently, onl y one water bod y, North C reek in Botetout County, has b ee n designated an Exce pti onal Water in Virginia. P ennsylvania Because Pennsylvania did n o t enact leg - islation specific to the Bay Agreem ent it does not hav e the critical areas and Bay acts that were adopted in Virgin ia and Maryland. What is in p lace however is stro ng legislation that allow s for local gove rnments to plan for and protect their local waterways. Pennsylvania's Municipal Planning Code Pennsylvania's Municipal Planning Code (M PC) gives primary responsibility for regulating land u se and development to loca l munici paliti es. U nder this code land ca n b e zoned and d esign ated for appro priate u se . Section 603 of the MPC specifically autho rizes lo ca l governments to regulate, permit, prohibit , restrict and determine u ses of land , including we t - lands and r iparian zo n es. The Code states that zo nin g ordinances must be designed to "promote, protect and faci li- tate ... prese r vat io n of the natural, scenic, and historic values in the environme nt and preservat io n of forests, wetlands, aq uifer s, and floodplains." (MPC Articl e V I , § 603 )."Provisions a dded to the Code in 2000 gave additional planning powers to towns and co unti es . The Growing Green er Program provid- ed funds fo r la nd co n servation, stormwater management, stream resto ration and oth er water qual ity improvements . In 1988 the "Environmental R ights Amendment" of the Pennsylvania Constitutio n (Act 1, Sectio n 27 and 28 ) was adopted . This amendment expre ssly gives local gov- ernm ents the a uthority to reg ulate the protec tion of s treams and rivers . Pennsylvania Tributary Strategies The tri butaries in the Commonwealth of Pennsylvania co ntrib ute a significant portion of the nutri ent loads being trans- ported to the Bay. Two of the Bay's major tributari es, the Susquehanna and Potomac Rivers, co mprise 21,000 square miles of the Bay's 6 7,000 square mile drainage areas. Pennsylvania formalized their effo rts to meet the req uire m ents set out in the Bay Agreement through their Nutrient R eduction Strategy, which is h eaded b y the Pennsylvania D epartment of E nvi ronm ental Protec tion . Pennsylvania's Strategy can be looked at in two parts: nonpoint and point so urce nutrient loads. The majority of nonpoint source pro- gram s in Pennsylvania target the agri- c ultural community, since it accounts for the majority of nonpoint nutrients deliv - A Strea m Corridor Protec tion Strategy for Local Governments 61 ered to the Bay by the tributaries within the state. The primary elem ents of the nonpoint strategy incl ud e: • Nutrient m anagement legislation • The Conservation Practice Installation Program, which focuses on the installation of BMPs • Agricultural initiatives, such as barn - yard runoff controls and stream corri- dor protection • Support for voluntary efforts • Urban nonpoint so urce control initia- tives, su ch as the Urban Erosion and Sedimentation Control Program and the Urban Stream Corridor Protection initiative The Commonwealth's point so urce pro- gram foc u ses on: • The phosphate detergent ban estab - lished in 1990 • Increased nutrient removal efficie n cies at wastewater treatment facilities • Private sector voluntary pollution pre- vention measures Central to the Pennsylvani a program is the tenet that no mandat es or initiatives wi ll be established for m eeting target goals without supporting funding. 62 Appendix C: Legislation and Agreements 303 ( d) list: State-wide lists of impaired streams that are not in compliance with state and federa l standards benthic: bottom (as in bottom -dwelling organisms) BMP: best management practice CBLAD: Chesapeake Bay Local Assistance Department (Virginia) CBPA: Chesapeake Bay Preservation Area CVMP: Citizen Vo lunteer Monitoring Program (Pennsylvania ) DEP: Department of Environmental Protection (Pennsylvania) development credits: Allowances for higher density or other exceptions in exc hange for environm ental protections EPA: Environmental Protection Agency GIS: Geographic Information System, a series of map layers used to show land uses LGSS: The Bay Program's Land, Growth and Stewardship Subcommittee LOD: Limit of Disturbance macroinvertebrates: Aquatic insects and larvae without a backbone, able to be see n by the unaided eye MIF: Minimum In-Stream Flow standards MPC: Municipalities Planning Code (Pennsylvania) NPDES: National Pollutant Discharge Elimination System which regulates discharges to waters of the United States overlay zone: Zoning which supercedes existing zoning PD Rs: Purchase of Development Rights proffer: Something given in exc hange for development vari- ance such as donatio n of a building or road improvements PUD: Planned unit development which requires a master development plan and generally additional requirements such as buffers around the d evelopment receiving area: Area receiving additional densities in exchange for preservation of land elsewhere RSCOD: River and Stream Corridor Overlay District sending area: Area ofland for which densities are reduced in exchange for development elsewhere, generall y to protect sensitive areas such as headwaters Glossary sheetflow: uni form flow of water in a sheet-like pattern, as opposed to in a gully "takings" test: A legal test to determine if land has been taken without just compensation TMDL: Total Maximum Daily Load , the maximum pollu- tant level for a stream that will allow it to meet water quality standards TD R s: Transferabl e Development Rights vanance: A legally allowed exception to a statute , granted by a regulatory authority USGS: United States Geological Survey VEMP : Volunteer Environmental Monitoring Panel (Pennsylvania) A Stream Corridor Protec tion Strategy for Local Governments 63
