With this came a realiza- tion that specific issues of com- munity appearance could best be addressed by developing and adopting a comprehensive stree- tscape program for the city that would provide guidelines for both public and private develop- ment within thoroughfare corri- dors. In March of 1991 the plan was authorized which, when adopted, will work in concert with the city's Zoning Ordinance to give specific direction to land owners, devel- opers, and the city itself in enhancing development within and along the major public corridors, General Study Area While this plan is drafted for the city as a whole, certain target areas were identified to "test" the guidelines as well as to provide pilot projects that could be implemented in the near future. The overall strate- gy of these pilot projects is to provide several early examples of the benefits of the streetscape program and to promote these benefits to the local develop- ment community, landowners, and community leaders. The pilot projects are: • The Northgate Area in- cluding a pedestrian mall pro- ject in the commercial area between the 300 and 400 blocks of University Drive and aesthet- ic improvements in neighboring residential areas through street - scape enhancement. • The Eastgate Area at the intersection of Texas Avenue and Walton Drive. This street - scape plan should include work- ing drawings, ready for physical implementation, specifying r ,. r C, TEXAS AVE. NORTHGATE (Q EASTGATE TEXAS AVE.

This segment of roadway is scheduled for major improvements by SDHPT. Any design plan for this area should include bike paths. L. ) 1 7-_ I `. JL _.. _ - 7 College Station Streetscape Study - Page 5 City Development Evolution and Trends College Station has evolved over the years from being a town that existed because of a local university to a small thriv- ing city with a solid, albeit small, retail, commercial, and industrial base. The period from 1980 -1990 saw strong overall growth occur to the south along the Texas Ave./ Highway 6 corridor primarily because of undesirable constraints to the east and west sides of the city and the exis- tence of support infrastructures to the south. Land use changes as a result of that growth are depicted on Table One. Land Use Category Right -of -Way Railroads Public Parks Vacant Multi- family Single - family Commercial Industrial Texas A &M Other TOTAL CHANGES IN LAND USE TYPES - 1982 TO 1989 TABLE ONE Inventory in Acres 1982 1989 Page 6 - College Station Streetscape Study According to a study conducted by the city planning staff, the areas of greatest commercial growth occurred along the north side of University Drive and in the area bounded by Texas Avenue, Highway 30, the ex- tension of F.M. 2818, and the East By -Pass. growth in these areas consisted mostly of office and retail operations. A second area of strong retail commercial growth occurred in the area bounded by Texas Ave, Rio Grande, F.M. 2818, and Dea- con Drive. Development is expected to continue southward as the city grows to its year 2000 popula- tion estimate of 71,000.

With these emerging develop- ment patterns it is important that a streetscape plan be devel- oped and adopted to ensure that future development occurs in a manner that enhances the ap- pearance of the community. Goals and Objectives Two general goals were devel- oped by the Streetscape Com- mittee to articulate the project ideals and direction: • Improve community appear- ance and project a quality image and character of College Sta- tion. • Improve the aesthetic quali- ty and bring unity and identity to city thoroughfares. In order to present measurable responses to the above goals, the following objectives were developed by the Streetscape Committee: • Create identity and continu- ity through landscape /aesthetic improvements adjacent to thor- oughfares. • Create a community identity I I I I I I I 1 I I t I I I I I I I I and a "sense of arrival" via City entry signs and landscaping entry points. • Develop conceptual designs for paving, landscaping, corner treatment, and street hardware for major and secondary inter- sections. • Develop streetscape designs that are low maintenance, sim- ple and not overpowering, that provide identity to create a quality image, and that provide unity and consistency that will link the various projects throug- hout the City. • Develop streetscape design concepts and associated land- scape and street hardware stan- dards that are unique to College Station and that are practical and implementable. • Develop standards for unified signage, street lighting, street furniture, and traffic signals to incorporate into stree- tscape projects. • Further develop and incor- porate the existing sidewalk and bikeway plans into streetscape planning projects. • Identify State and local roadway improvement projects where streetscape plans could be incorporated. • Investigate all possibilities and area locations eligible for SDHPT's Landscape Cost Shar- ing Program. • Review and recommend revisions to applicable portions of the City's subdivision and landscape ordinances as well as other development policies. • Develop a streetscape plan for the east side of the Univer- sity /Walton Drive intersection (Eastgate) as a pilot project in accordance with recommended plan guidelines and standards.

This section will identify and docu- ment those factors. So ils The various soil groupings found in College Station are depicted on Exhibit One and are taken from the U.S. Soil Conservation Service survey. While there are a variety of soils spread over the area there are common characteristics which are evident. Most of the soils are clayey low productive soils with low natural fertility suitable mostly for pasture -land unless amended appropriately for landscape development. These are primarily the Crock- ett, Edge, Lufkin, and Tabor series. Drainage characteristics of these soils vary but are pre- dominately poor drained, fine grained, and possess low per- meability. The most fertile soils are found along floodpl- ains and creeks, as well as beyond the city limits in the bottomland of the Navasota and Brazos Rivers. These fertile soils are primarily the Axtell, Gowen, and Ochlockonee, and are present within the city limits along Carter's, Wolf Pen, White, and Lick Creeks. The various soils located within the College Station City limits can be found in the Appendix. To accommodate landscape development that may be re- quired by a streetscape plan, soil amendments and drainage provisions should be made to assure long term ornamental plant health. Vegetation The extent of existing vegetation should play a large role in determining overall streetscape concepts especially regarding setbacks and landscape reserves. A well conceived plan will utilize existing vegetation by encourag- ing mechanisms for preservation and incorporation into any proposed development. This does not appear to have been the case for the most part in previous development around the city. Most commercially developed areas have given little thought to preservation of existing vegetation. The largest masses of natural vegetation occur along Carter's and Wolf Pen Creeks as well as in unde- veloped tracts along FM 2818 and University Drive. The present tree cover is shown on Exhibit Two. Within all of the areas are outstanding examples of hardwoods and typical under - story growth. With the exception of Texas A &M, few developments have done any planting in the public rights -of -way. Tree cover, therefore, along these thorough- fares is quite sparse and uncoor- dinated. Floodplains Major 100 year floodplains are depicted by Exhibit Three. These are the floodplains associated with Carter's Creek, Wolf Pen Creek, White Creek, Lick Creek, Alum Creek, Spring Creek, Bee Creek, and Peach Creek. These drainageways traverse the city and provide natural greenways except at those areas that have been altered by roadway cross- ings or channelization. Many of the floodplain areas are to be conserved as parkland as pro- posed by the long range city land use plan. This will pro- vide fingers of green throughout most of the city's existing and developing residential areas.

L t 1 1 1 i 1 1 1 1 1 1 1 1 1 MAN MADE INFLUENCES Land Use/ Development Areas Future land use is shown on Exhibit Four. This is a repro- duction of the updated compre- hensive plan 2000 and provides direction and guidance for city growth. This plan recognizes that most growth will continue to occur to the south because of natural development constraints to the east and west. It calls for retail, commercial, and higher density residential uses along the major access routes into the city, which the street - scape plan will address. There is currently proposed an indus- trial district east of the East By- Pass at the University drive interchange in floodplain area of Carter's Creek. This particular site should be developed with great care as it is adjacent to a major portal of the city and contains large stands of existing vegetation. Utilities Locations of major utility lines (i.e. water, sanitary sewer, gas, storm sewer, telephone, and underground and overhead power lines) are indicated on Exhibits Five, Six, and Seven. Locations of these utilities will effect tree plantings within the R.O.W, Thoroughfares affected the most are Texas Avenue, University Drive, Highway 30, Holleman Drive, and Southwest Parkway. Drainageways and Culverts Open drainageways exist along at least one side of major thor- oughfares in most all locations of the city. The major State highways (i.e. Texas Ave., University Dr. , F.M. 2818, Harvey Rd.) handle drainage in an open drainageway in a ma- jority of instances. These drainageways have poorly main- tained side slopes and, in most areas, prove difficult to main- tain for both the State and adjacent property owners, re- sulting in unsightly conditions along highly traveled and im- portant visual corridors. Thoroughfare Rights -of -Way The ability to conceive and carry out a successful street - scape scheme depends largely on the amount of right -of -way within which one has to work. This also determines the degree of public /private participation that the plan will recommend. Exhibit Eight indicates available planting space between the roadway and right of way on major city thoroughfares. This information combined with visual verification indicate very tight areas along the major corridors into College Station especially Texas Ave., Highway 30, and portions of University Drive. These areas will require cooperative strategies with existing property owners to achieve a balanced well coordi- nated plan. Signage Signage as an element of the streetscape (building signage excluded) was reviewed in light of the current City sign regulations. The regulations adopted by Council set up • a reasonable system of controls which keeps the City free from adverse effects of unregulated signage. No major abuses or violations of the ordinance were noted during site analysis. It was noted that certain major intersections are not signed and that there is an absence of major informational or direc- tional signage to the University with the exception of the exit signage at the East By -Pass.

Views and images will be analyzed by major thoroughfare as follows: Texas Avenue There are minor positive long views of the University at the Texas Avenue /Greens Prairie Road intersection and additional scattered positive views moving northward along Texas Avenue. There are pockets of visual clutter along Texas at the retail - /commercial nodes especially in the vicinity of Southwest Park- way and between Highway 30 and George Bush Drive. From the College Station City Hall northward to University Drive is a zone of major visual clutter of retail and commercial establishments with varying setbacks, unscreened parking, and little or no vegetation. The Eastgate retail areas contains several viable businesses, but the appearance of the area is unkept and run down. At such a prominent location across from the main entrance to the University, this area should be upgraded as soon as possible. The view down New Main westward from Texas Avenue conveys a very strong ceremo- nial feel to the approach into the University. Eastgate Commercial Area View Westward Along New Main College Station Streetscape Study - Page 31 Continuing northbound on Texas, the views to the west toward the University continue to be very strong and are the most significant in the city. Continuing northward on Texas Avenue past University to the city limit line, commercial development crowds the Texas Avenue R.O.W. with little or no landscape development or screening. East By -Pass Views along the East By -Pass are generally good because of the large amounts of existing vegetation. The Texas Avenue /East By -Pass inter- change is a major visual focal element that should receive special consideration. Highway 30 Exiting the East By -Pass and traveling along Highway 30 the drive -by image is one of minor clutter of various retail /commercial and multi- family developments. The undeveloped areas of the Wolf Pen Creek corridor provide a soft green image along the south side of Highway 30 be- tween Texas Avenue and Dart- mouth Street. Landscape devel- opment to existing businesses is more evident on the south of the highway than the north. University Drive Page 32 - College Station Streetscape Study Exiting and driving west from the East By -Pass the image is soft and green because of the existing hardwood grove. The straight -ahead view focuses on the monument tower at the Chimney Hill retail center. As the center is approached the masses of trees are replaced by parking areas all landscaped with mixed success. From Tarrow Street west to Texas Avenue there is retail/ - commercial clutter on both sides of the highway. At the Texas Avenue intersection the pan- oramic view of the University University Drive Median in the distance is probably the strongest and most significant view in the entire city. Continuing west along Universi- ty Drive has recently been redeveloped with pavers and ornamental trees by the State Department of Highways to provide some visual relief to the six lanes of pavement. The intersection of University and South College has also been landscaped recently with pavers and small flowering trees but the size of the material utilized in both areas seems inappropriate for the space of the intersection and R.O.W. 1 1 1 t s 1 t 1 Continuing west, the north side of University becomes cluttered with small retail /commercial establishments. At Tauber Street the A &M Methodic+ Church provides a brief visual break but from Lodge westward to Wellborn Road the Northgate commercial area provides major visual clutter. University Drive has encroached upon these establishments to the point that sidewalks are too narrow for the volume of pedestrians that wish to use them. Parking along University has been reduced to parallel. Storefronts here have no consistency of style giving the entire area an undesirable appearance. Leaving the Northgate area the next major view is of the Well- born Road interchange and continuing west from there the University controls land on both sides of the highway. The image in this area returns to a softer, greener feel with the exception of the Veterinary Medicine School Complex which has parking along the highway. The remainder of University Drive to FM 2818 passes through University land. The TAMU Research Park has developed a very positive image through appropriate plantings, portal elements and other street - scape related items. Northgate Commercial Area TAMU Research Park College Station Streetscape Study - Page 33 FM 2818 Traveling south along FM 2818 from Bryan, the University Drive interchange marks the entry into the College Station City Limits. Image here is rural because of the large amounts of undeveloped land. Therefore it will be important to convey a sense of arrival into the city through the use of portal development. As one continues southward along FM 2818 the image remains rural and pastoral because of the amount of undeveloped area. Between Wellborn Road and Texas Avenue development is sporadic with no significant image concerns or views. George Bush Drive Traveling west along George Bush Drive from Texas Avenue the views toward the north to the University are significant. This thoroughfare has probably the best image of all the streets in the city primarily because of the University to the north, the well established residential area to the south, and the median of existing oaks between Timber Street and Dexter Drive. West of Fairview the Southside retail area again brings visual clutter into the visual experience. Continuing westward, George Bush Drive enters University property and eventually termi- nates at Easterwood Airport. Page 34 - College Station Streetscape Study Sidewalks and Bikeways View Eastward Along George Bush Drive The City of College Station is currently working toward the adoption of a bikeway and sidewalk plan. Because of the City's size, the location of the University, and other elements that make the area attractive for development of an extensive bikeway system, the City has put a priority on completing a bikeway system. Because of the close relationship of the sidewalk system to the bikeway system the existing conditions of both systems have been evaluated concurrently. Sidewalks Data collection revealed no uniformity to sidewalk locations, widths, setbacks, etc. A review of the City Subdivision Regulations found walks required on most streets but their location within the public R.O.W. was very flexi- ble confirming the lack of uni- formity observed. In a few instances walks exist about the City with "parkway strips" that are awkward and cause high maintenance in terms of trim- ming and edging. The city Subdivision Regulations state that sidewalks are optional along residential streets and many of the newer subdivisions reflect this, forcing residents to walk in the street. The four foot minimum sidewalk width as required by City regulations appears too narrow in most locations, especially in those few instances where the side- walk abuts the curb. t t I IOW 1 I 1 I 1 1 1 1 t 1 t 1 1 1 1 1 I 1 1 1 Bikeways The College Station area has a high amount of bicycle traffic and, as a result, the City has initiated a program to provide for an organized bikeway system. The current system is a combination of "bike lanes" where a portion of the street or shoulder is striped, signed, and marked for exclusive bicycle use, and "bike routes" where motorists and bike riders share the roadway. Few separate facilities for bicyclists exist. At present, bicycles are restricted from the high vehicular volume thoroughfares such as Texas Avenue, University Drive, FM 2818, and Highway 30. More use should be made of existing parks and future linear parks for development of bike path facilities. Sidewalk and Parkway Strip in Residential Area Bike Route College Station Streetscape Study - Page 35 OPPORTUNITIES AND CONSTRAINTS The City of College Station is faced with very real constraints in achieving a streetscape plan but there are also some clear opportunities as well which should be understood and capi- talized on. Exhibits Ten and Eleven illustrate potential areas for tree planting based on analy- sis of utilities and existing tree cover. Exhibit 12 illustrates opportunities related to portals, thoroughfares, and intersections. Opportunities The City is fortunate to have a great deal of undeveloped land within its boundaries thus giv- ing it much needed flexibility and freedom to create a street - scape program that will show results as development occurs in the coming years. The fact that the City has a landscape ordinance setting forth minimum landscape re- quirements for development provides an opportunity to insure a continued standard of visual quality in development. With a few well conceived modifications to the ordinance this aspect can be strengthened even further. Primary approaches to the city on the major thoroughfares are uncomplicated and the various Page 36 - College Station Streetscape Study interchanges along the East By- Pass and at FM 60 and FM 2818 make logical choices for future portal development. The overall visual image of College Station is good and conveys the notion that this is a friendly, safe, community in which to live and work. The streetscape plan can build on that strength to provide an even stronger sense of visual continu- ity. Texas A &M adds a very strong and positive image to the city that should be recognized and fostered. The existing Parks and Open Space System provides a strong green image to the city that will be enhanced even further as a proposed linear greenbelt system is imple- mented. The fact that Texas Avenue is to be widened along the length of the Texas A &M frontage presents an opportunity to incorporate streetscape design concepts into this project.

Constraints There are some very real constraints to the streetscape program that must be clearly documented and understood so that the plan can make as strong an impact as possible given these existing conditions. Existing Utilities Existing utilities from overhead power and phone lines to underground gas, water and sewer lace the rights -of -way and present potential conflicts to tree plantings and other related streetscape development. Rights - of - Way As Exhibit Eight indicates, the available R.O.W. for street tree planting is very limited along the major thoroughfares. Compounding this constraint is the existence of drainage channels with much of this right -of -way along Texas and University as well as the fact that many existing developments have built out to the right -of- way in these areas leaving limited room for any public sponsored development. This problem is particularly acute in the Northgate Commercial area. Existing Primary and Secondary Thoroughfares A major portion of the City street system is relatively new and, as a result, streetscape recommendations affecting roadway alignments, median placement, etc. should be kept to a minimum. Likewise, most major intersections are new or recently modified. Any streetscape guidelines affecting them should be long term in nature.

Because the City of College Station has very few medians to establish a strong planting concept in the center of the street, and also has very wide rights -of -way, the tree themes should be kept quite simple and direct. On special streets, one or two tree species make the strongest visual impact distinguishing the street corridor from private development. On smaller less important streets, the tree specie list is more general to offer the greatest 110 variety in tree form, texture, seasonal color, and flower. The specie selection is based on hardy, native tree stock generally available in the industry that relates to differing private developments and site settings such as existing trees, topography, and drainage conditions. The following Street Tree Planting Themes shall apply: Corridor A - University Drive. A formal row of Water Oaks, regularly spaced. Irregularly spaced Live Oaks and Red Tree Crapemyrtle shall be used on the north edge of the TAMU campus between Texas Avenue and Wellborn Road integrating into the same species planted along the campus edge. Water Oaks are an excellent upright oval form street tree with yellow fall color that is hardy in the area. This large growing shade tree, when used fronting commercial areas, allows view under and around its upright oval form to graphics and signage beyond. Corridor B - Texas Avenue. A formal row of Live Oaks regularly spaced with single, formal rows of Tree Yaupon temporarily used under overhead utility lines. Red Tree Crapemyrtle shall be used informally as understory flowering trees between University Drive and George Bush Drive across the east edge of .the TAMU campus. Use of the Live Oaks with their evergreen quality strengthen the existing Live Oaks along the east campus edge and make it a logical choice for this corridor. College Station Streetscape Study - Page 45 Corridor C - TAMU Core Campus Edge. Informal plantings of Red Tree Crapemyrtle along with loose plantings of Live Oaks ring this older historic core of the campus. The Red Tree Crapemyrtle long blooming period and fall color make it an excellent choice. Corridor D - George Bush Drive. Formal rows of Red Oaks regularly spaced. Red Oaks were chosen because of their stately form, seasonal color, and the ability of obtaining matched specimens that are readily available in the industry. The new main entrance to the Presidential Library site should allow the library project tree, when selected, to dominate the trees selected in the immediate area. Corridor E - Highway 30. Informal plantings of Cedar Elm and White Tree Crapemyrtle. Cedar Elms should be used along the ROW edge as the primary tree. Their up -right form and potential large size will allow views under their canopy to commercial signage and graphics. White Tree Crapemyrtles are selected for their long blooming periods and should be used to provide continuous accents of color along the corridor. Corridor F - Wellborn Road. This major north /south corridor provides major access to the Page 46 - College Station Streetscape Study TAMU Campus. Informal groupings of Willow Oak and Cedar Elm as the primary shade tree with accent ornamental tree planting of Red Bud and Tree Yaupon is the tree selection for this corridor. These tree species should integrate well into the existing forested areas to the south and the more urban areas to the north. Corridor G - F.M.2818. This western and southern loop around the city has many undeveloped parcels of land with stands of native trees. With many new developments that will save the existing trees on private property, it is important that the tree theme on this corridor remain as natural and varied in tree species as possible. Shade and ornamental trees should be selected from the "Major Arterial Group A" plant list. Corridor H - All Minor Arterials. Because of the desired need for variety in street tree planting, primarily within the residential streets of the City, informal tree plantings should be selected from the "Minor Arterial Group B" plant list. Reference Exhibit Thirteen. Special streets such as the major arteries of University Drive and Texas Avenue link main visitor approaches to the University. The articulation of these impor- tant corridors should be simple and direct, providing a strong connection from perimeter East Bypass, FM 2818 loop as well as at the city limits on Texas Avenue. A "frame of key streets" around the older portions of the university include Texas Avenue, University Drive, Bush Drive and Wellborn Road. These streets should be closely inte- grated into the campus edges forming a stronger campus perimeter. The other key factors in im- proving the visual appearance of the city include: • Strengthen the landscape ordinance as it applies to the screening of parking and dump - ster locations. • Provide a stronger emphasis on denser landscape develop- ment of site perimeters rather than the interior portions of sites. • Provide stronger incentives and guidelines for saving exist- ing trees particularly in the south and southeastern portions of the city. • Require additional tree planting for properties adjacent to Major and Minor arteries. • Encourage private partici- pation in planting trees on properties along Collectors. • Strengthen the City stan- dards and regulations on walks, drainageways and bike systems. • Establish continuity in pro- viding a "family of streetscape elements" to improve the stre- ets' visual appearance. The streetscape plan should have a level of flexibility in its implementation. Special project areas such as Texas Avenue, Eastgate Entry Parks, Northgate Commercial Area, and the FM 2818 Portal at University pro- vide initial project areas to encourage community involve- ment in implementing the plan. College Station Streetscape Study - Page 47 GUIDELINES AND CRITERIA To achieve the concepts out- lined in the previous section, the following Guidelines and Criteria have been developed which address implementation strategies.

While it would be a desirable goal to allocate specific areas within the R.O.W. for each element it is important to recognize that as conditions vary about the City it might be necessary to shift locations of certain elements. PR/VATE ,ea°f Arterials, Parkways, and Commercial The Streetscape Plan therefore recognizes and encourages this need for flexibility and recom- mends the following general guidelines: • Residential and Collector Pedestrian Zone - Located on both sides of the street; minimum width six (6) feet (final width requirement should vary based on amount of pedestrian traffic anticipated). Utility - Located on both sides of the street between the pedestrian zone and the R.O.W. line. • Arterials, Parkways, and Commercial Pedestrian Zone - Located on both sides of the street; same width requirement as above. Utility Zone - Located directly in back of curb on both sides of the street. College Station Streetscape Study - Page 51 Creation of Landscape Reserves To foster the development of a greener, softer image along the major and minor arterial thoroughfares of the city, it is recommended that the minimum setback requirements along site perimeters adjacent to these thoroughfares be increased from eight (8) feet to twenty four (24) feet. Parking will be permitted within these landscape reserves when appropriately screened in accordance with guidelines outlined below in the Parking Screening Section and when broken up by randomly placed islands with minimum spacing of twenty -seven (27) feet to a maximum of sixty - three (63) feet. Existing trees shall be preserved within these landscape reserves. Point credit toward the existing landscape ordinance will be allowed if existing trees are protected in accordance with guidelines outlined below under Preservation of Existing Trees and Natural Resources. Point credit toward the existing landscape ordinance will be allowed for landscaping these reserves with groups of shade and ornamental trees when no trees exist. Specific require- ments for the different street hierarchies are as follows: Along major arterials where no trees exist it will be required to provide one shade tree (min. Page 52 - College Station Streetscape Study 4" cal.) per 25 lineal feet of landscape reserve. Two orna- mental trees may be substituted for one shade tree. These trees should be loosely spaced in an informal arrangement. Along Texas Avenue and Uni- versity Drive it will be required to place water oaks (min. 4" cal.) at 60' o.c. Where overhead utilities conflict, small trees (tree yaupon, min 8' -10' ht.) will be planted until utilities are placed underground. Along minor arterials where no trees exist it will be required to provide one shade tree (min. 4" cal.) or two ornamental trees per 32 lineal feet of landscape reserve. Figures 1, 2 and 3 illustrate the requirements of the landscape reserves. } p R / L/ N - M /N• Figure 2 - Landscape Reserves r I.x moo, iF07KTE0 } AFEA '� J I� i'►�' Il \ \\ • TI•EES L' ATED IN Pf•ONT OS HEAD - lN PAgNNr s441.1- fAve 5/KE nE rueEA1 e, c# Ar to AND PAce a` Tfe • r - o/i/pp 7PeE PPoTe .77o// Pu 1N6, CaNSTieucT/HN. • ,WU/Nn4D- /N PA -IA . 08') /N7o EDGE ar :Cev° on,/ , 411AM wC -P PARKING, KLANOS er-sa /v4 AT A M /N.

It is therefore recommended that a requirement for screening parking be instituted with the following criteria: • A minimum three (3) foot height screen shall be placed between all parking areas and major thoroughfares. This screen can be vegetative (hedge), structural (low wall), or earthen (berm) or any combi- nation of the three. Refer to Figures 5, 6 and 7. • Planting screens and struc- tural walls shall be no closer than 30" from back of adjacent parking area curbs to allow sufficient room for bumper overhang. This overhang area should be treated with a low groundcover, bark or rock mulch. Refer to Figure 5 and 6. • Berms should be simple in shape with a more horizontal profile than vertical. Maximum slope on berms should be 1:3 or one foot vertical rise for every three feet horizontal. Refer to Figure 7.

The plant materials included should com- prise the major components of landscape development. Since these materials serve a specific function, any variance would tend to weaken the overall design intent. The plant materials suggested are only those which are consid- ered native or which have prov- en satisfactory for the College Station area. Careful consider- ation has been given to selection of plant materials which are considered easy to maintain, generally free of insects and disease, and relatively hardy for this area. Plant materials shown in the list should also be considered for private develop- ment, but should not be viewed as the only plants acceptable for use. General Planting Procedures and Guidelines As was explained in the previous section, the College Station area is made up of variable topsoil and subsoil conditions, and detailed soil requirements will vary from area to area. The topsoil gener- ally is made up of heavy clay. Considerable conditioning is needed to promote adequate plant growth and lower long - range maintenance costs. Sub- soil drainage, especially in the areas of deep cuts or where heavy equipment is used, pres- ents serious problems to tree plantings. Clay soil conditions tend to hold water in the tree pits and additional drainage provisions should be incorporat- ed wherever these conditions prevail. Thorough analysis must be given these problems, and measures must be taken to ensure adequate porosity of all subsoil around planting areas. Trees will grow in the existing soil, but in order to promote quick recovery from the trans- planting process, it should be RUBBER HOSE LEAVE LOOSE AROUND TRUNK TREE GUYS - REF.SPECS GALVANIZED WIRE BARK MULCH FINISH GRADE UNDISTURBED SOIL 4' PVC SUMP W/ CAP FILTER FABRIC PEA GRAVEL BACKFILL PER THE SPECIFICATIONS SUMP DRAIN required that backfill containing five (5) parts sandy loam and one (1) part peat be placed around the balls of all new trees. Large shade trees should have pits two (2) feet greater in diameter than the size of the ball. The sides and bottom of the pits should be scarified to increase porosity and to help root penetration into existing soil. Care should be taken to ensure planting trees at proper depth and to prevent settling of the soil. All trees should be set so that the top of the ball is even with the finish grade. (Refer to Figure 12 for example.) For those on sloping areas, the top of the ball should be even with the downhill side. Figure 12 - Tree Planting IAMETER 7 TRIP GUARD PECS. ANCHOR College Station Streetscape Study - Page 57 Shrubs and groundcover require similar bed preparation. Bed areas require a minimum exca- vation depth of six (6) inches. The excavated soil should be removed from the site and the beds backfilled with a thorough- ly mixed and prepared soil containing one (1) part sandy loam, one (1) part peat moss, one (1) part sharp sand. Four (4) pounds of commercial fertil- izer should be added for each 1000 square feet of bed area. Shrub and groundcover areas which occur on compacted fill should have twelve (12) inches of prepared soil. Bed areas which occur on slopes greater than 3:1 should be covered with jute matting to prevent erosion until the plants are established. Once all bed preparation has been accomplished, the plants should be spaced according to specifications and set with top of balls even with the top of the bed. Soil should then be com- pacted carefully around each plant and well watered to elimi- nate air pockets around the roots. Lawn areas should have a mini- mum of four (4) inches of existing topsoil over regraded subsoil. Drainage is vital and it is often expedient to cultivate sand or sandy loam into the upper four (4) inches of soil to permit fine grading. All lawn areas should be fine graded to establish a smooth, even grade suitable for a fine lawn. Any undulations that cannot be raked Page 58 - College Station Streetscape Study out should be topdressed with sandy loam. Stones one (1) inch or larger, sticks, roots or other debris exposed during this operation should be removed from the site. Areas showing weed growth shall be sprayed with approved herbicides, mowed and the clippings re- moved from lawn areas prior to final grading. Lawn areas with solid sod application should have sod placed so edges are touching, topdressed to fill voids with sharp sand and rolled to elimi- nate undulations. At the time of seeding, the soil should be moist, but not muddy, and the wind velocity should not exceed ten (10) miles per hour. Add water, if required, to moisten soil. Scarify the ground with a rake, as necessary, immediately before sowing seed to provide a smooth, even grade and friable seed bed. Hydromulch seed evenly at the rate of eighty -six (86) pounds of Bermuda Grass per acre in irrigated areas, or eighty -six (86) pounds of Buffa- lo Grass per acre in non- irrigat- ed areas with wood cellulose fiber at the rate of fifty (50) pounds per 1000 square feet. Add tackifier to mix for 4:1 slopes or greater at the rate of one (1) pound per bag of mulch. Lawn areas which occur on slopes exceeding 3:1 gradient shall be strip or solid sodded. Drainage swales or channels should be protected with solid sod and /or erosion control matting as required. During construction, temporary measures should be taken to prevent erosion and sediment build -up of designed drainage ways. Irrigation Guidelines It is recommended that a fully automatic irrigation system be mandatory to support new landscaping at required parking area screens and street tree planting. The balance of the landscaped areas should be within 100 feet of a hose bib or quick coupler valve, however it would be highly desirable for all landscaped areas to be watered by a fully automatic system. Open Drainageways and Culverts Because a large portion of open drainageways exist on State Rights -of -Way it will be difficult to quickly incorporate the following recommendations in these areas. However, the City should quickly move to incorporate the following guide- lines into the appropriate sec- tions of the development codes. • Drainageway Cross - section Drainageways with grass slopes shall be graded with 1:3 maximum slopes with the flow 1 1 t line of the drainageway stabi- lized with solid sod or jute mesh. Refer to Figure 14. • The City should take steps to reduce the visual impact of culverts by requiring that drain pipe beneath streets extend far enough beyond the streets to allow headwall construction that is of a lower profile and less visually obtrusive. Refer to Figure 13. • MEeT 5TA7E REOUMEMEM7 PAZ WALL MATbC/ALS AND ca/H4 UR4770V • WALL fMO/1 To /417cN- /YwarcrURE Figure 13 - Culverts • Whenever possible, side - walls of drainage structures should match grade of adjacent sideslopes to minimize the visual impact of the structures.

This importance should be recognized early in the planning stage of a project and Project Review Committee (PRC) review should stress that developments give appropriate locations serious consideration. In order to reduce visual clutter and unsightly conditions concerning trash storage and pick -up, the following guidelines for dumpster placement and screening on private property should be adopted. • Placement - Dumpsters shall be located in the rear yard of commercial establishments out of view of major thorough- fare rights -of -way.

Dumpsters located in sideyards must be screened with a structural screen of a wood or brick enclosure. College Station Streetscape Study - Page 61 Design Standards Design element guidelines have been developed for the following major components of the streetscape system: • Lighting • Furniture • Signage • Traffic Signalization • Surface Elements (Sidewalks, Crosswalks, Intersections) • Special Elements The following pages will de- scribe each element, the con- cepts which directed design and the criteria for placement. Lighting Lighting standards and guidelines have been developed to achieve three major objectives: • Consistency - Fixture Style in R.O.W. - Lamping • Flexibility • Control of light spillage There is a strong need to provide a consistent level of lighting along the major thoroughfares of the city. To that end it is recommended that a concealed source fixture be used equivalent to KIM Light - ings CCL Luminaire. Lamping Page 62 - College Station Streetscape Study recommendations are as fol- lows: • Special Streets (Texas and University) - Metal Halide • All Other Streets - High Pressure Sodium The City should prohibit the use of any other type of lamp except metal halide, mercury vapor, or high pressure sodium within the city on both public and private developments. It is recommended that the luminaire have dark gray finish. These fixtures would be mount- ed on 35' height dark gray anodized aluminum poles. Other manufacturers supplying equivalent fixtures to KIM are EMCO - "Infiniround" and Gardco "Form 10CA" . Roadways are classified by the Illuminating Engineering Soci- ety of North America as free- way, expressway, major, collec- tor, and local. Based on that classification fixtures should be placed to achieve the following footcandle levels and uniformity ratios: Major 1.2 Collector .8 Local .6 fc uniformity 3:1 4:1 6:1 vF 4 4 ;t yr aAFl - Figure 22 - Light Standard ,goasesipe SHIELD w • • L/C- ,h`rtA iAL"N ,t1E0oe1.rr uNes SHlALL- Ver HAVE al 5 /7e 5 C /LLAerE oot,1 Figure 23 - Lighting Recommendations • Vave AGL Pp4VA7p Deve(DPP£?t PARK /NE? /57REET 1J Mr5 ALOWT eP4,VTAhe 7� /NTC,¢/ae st7E O1 noN5 Figure 24 - Lighting Recommendations t 3 3 1 1 1 i a I In order to minimize hardware located at the R.O.W. lines it is recommended that private de- velopment parking area lights be placed internal to the site and away from the R.O.W. Refer to Figures 22 -24 for lighting recommendations. To promote flexibility of "character" lighting within special developments an alternative fixture can be utilized with prior City approval. This fixture, equivalent to Moldcast Washington Contra/Cline is a traditional type standard and luminaire, more pedestrian in scape , and suitable for subdivisions and other developments where a special fixture is desired. Lighting in public R.O.W. as well as private developments should be required where lighted parking areas and roadways abut residential areas. Site Furniture The purpose of providing furnishings in the street corridors is to permit functions to occur which do not presently exist. The furnishings should be of a quality that enhances but does not compete with similar items in private developments. The form and scale of the furnishings have been selected in an attempt to relate to the pedestrian when appropriate yet be in scale when viewed from the automobile. The forms of the elements are purposely simple to achieve a timelessness and so that each is aesthetically pleasing independently as well as in groups. • Benches Benches recom- mended are a stylized traditional form constructed of painted metal to match light fixtures and anchored in place by con- crete footings.

These units should be placed adjacent to structures when it is neces- sary that they occur in public R.O.W. They should be limit- ed to no more than four units at one location and be painted gray to match light standards and other site furniture. • Mailboxes Residential mailboxes located adjacent to street curbs shall be installed on metal posts painted gray to match other street furniture.

Because of the prolif- eration of signage necessary to maintain a semblance of control it is desirable to minimize these signs within the street environ- ment. Signs that are deemed necessary should be mounted and installed consistently throughout the City. Signs shall be mounted on gray anodized aluminum poles 2' -0" from back of curb, 5 feet above road surface for rural roads and 7 feet above road surface where parking will occur. Back of sign blade shall be painted to match poles. Refer to Figures 29 and 30. In an effort to improve orienta- tion within the city as to where major intersections occur it is recommended that: • Intersections of major arterials be signed by the use of sign blades located on traffic signal crossarms. • Approaches to major inter- sections be announced by appropriate signage located 500 - 750 feet from the intersection. Traffic Signalization In order to achieve maximum flexibility of required traffic signalization standards, the City should utilize a signal structure composed if mast arms, extensions for luminaries, etc. that are constructed of standard metal or tube steel components assembled in creative ways to College Station Streetscape Study - Page 65 satisfy unique requirements at specific intersections. Figures 31, 32, 33, and 34 illustrate potential flexibility of such a system. This configuration is recommended over other modular designs because of the components are more economical to replace in the event of damage and the design os more appropriate in less densely developed corridors such as those in College Station. In order to maintain a consistency of color in all structural elements within the streetscape, it is recommended that traffic signal poles and mast arms be of gray anodized aluminum or a sealed, powder - coat finish of a comparable color. Signal boxes should be painted to match poles. 4 CITY COGCXS • M4✓A/ -LiLUf Page 66 - College Station Streetscape Study is r e r e PA /,VT TO MATCH POKE LEFT TURN - PA /NT To Aorew POLL: c-rGrirls To EE PN /NTED 4.

The visibility of detail in the surface elements will permit a strong sense of scale relationship. Materials chosen are durable and proven. The designs in the major inter- sections (refer to the proto- typical plans section of this report) will provide a strong identifying element that differ- entiates the city's street hierar- chy. 14411.4k Sidewalks. In an effort to foster safer pedestrian movement it is recommended that four inch thick reinforced concrete side- walks be required along all streets in the city. On residential streets sidewalks should be located against the curb on both sides of the street and have a minimum width of six feet. j J 7. K Figure 34 - Sidewalk Locations and Widths On collectors and arterials sidewalks should be located on both sides of the street and be set back from the curb a mini- mum of six feet to provide an extra measure of pedestrian safety adjacent to these heavier travelled thoroughfares. Side- walk width should be a mini- mum of four feet. Refer to Figure 34. Along all streets sidewalk width should be reflective of the anticipated College Station Streetscape Study - Page 67 pedestrian utilization. Where collectors or arterials approach schools or libraries it would be appropriate to increase the sidewalk width to handle the increased pedestrian traffic. It is recommended that side- walks throughout the city be finished as detailed on Figure 35. This will provide a suitable level of detail and interest that is appropriate for pedestrian usage. Crosswalks. Crosswalks about the city should be marked on pavement with reflective pavement paint. Figure 36 indicates a prototypical marking recommendation at a bikelane and Figure 59 on page 90 illustrates crosswalk design at major intersections. While it is the intent to utilize pavers and enhanced paving only at special intersections such as Texas /University,Texas /George Bush, etc., it may be appropriate to provide crosswalks with pavers at streets in the Northgate district. Pavers at these crosswalks should be of a contrasting color to the adjacent street surfaces. Special Intersections. Major and special intersections shall be differentiated from standard intersections through the use of concrete pavers, sandblasted concrete finishes, troweled bandings, etc. Refer to Descriptions of Major Intersections for details.

Banners would be placed with special brackets mounted on special standards as shown on the Eastgate Prototypical Plan. In appropriate areas banners could also be mounted on street light standards. Banners should be 4' -4" by 14'- 8" long and manufactured of synthetic materials for durabili- ty. Seasonal Li ghting /Decorations.. This element is recommended to bring additional seasonal spirit to the city. Provisions for glitter lighting in the trees will be provided by duplex outlets at the base of the trees. BIKEWAY PLAN Introduction The Bryan- College Station area has a high amount of bicycle traffic in comparison to other similar sized cities due to the large number of TAMU students and faculty who find bicycling as a feasible transportation alternative. As a result, the City of College Station has initiated a program to provide for an organized system of bikeway facilities. Because of the close nature of the Streetscape Plan and the bicycle system this study will not only recommend design guidelines for the various paths, lanes, and routes that traverse the city but evaluate the existing routing and make recommenda- tions for specific improvements to future routing. Definitions A bikeway is a trail, path, part of a highway shoulder, sidewalk, or any other means specifically marked and assigned for bicycle use. Bike- way facilities are further classi- fied as bike paths, lanes, and routes. Bike Path - a facility complete- ly separate from auto traffic and within an independent right -of- way or within the right -of -way of another facility. Bike Lane - a facility where part of the roadway or shoulder is striped, signed, and marked for exclusive or preferential bicycle use and where vehicle parking is not permitted. Bike Route - a facility designat- ed by signing to help make the motorist aware of the presence of bicycles which share the right -of -way with motor vehi- cles. Bikeway Location Criteria Bikeway facilities are planned and located to integrate with the existing City street and Park system. The facilities are stra- tegically located on primarily a demand basis to minimize their numbers and to provide a bike- way to a certain areas or neigh- borhoods within the City. Important criteria used in deter- mining bikeway location are: • Safety. Existing street width. • Existing and potential de- mand for use. • Continuity and directness. • Spacing. Relationship to other bikeway facilities. • Location of schools and other public facilities frequented by bicycle riders. • Location of linear parks and greenbelts. Bikeway Design Criteria There are numerous design criteria to consider in establish- ing bikeways in College Station such as bikeway widths, sight distances, and intersection treatment. The width of a bikeway depends on the classifi- cation of bikeway, the edge conditions, and maneuvering allowance. Stopping sight distance for bicycles is general- ly not a problem since roadway alignment usually has been designed to accommodate auto speeds equal to or greater than bicycle speeds. Intersection treatment is very important as statistics indicate that about two - thirds of bicycle /vehicular accidents occur at intersections. The following design criteria for bike paths, lanes and routes were adopted by the City of College Station and taken from College Station Streetscape Study - Page 71 • A PATH G4 �EPAR4TEA PAW Al/To 7X4?P/c PREFEGf .L r /N THE Acioui .'YT of Rir1I LONCRETE PAd /N4 E `EDE57•PW to' MIMMUMINIPThi I D�S1?�E 2� FLANTEP f'a '!‹.E ; 47/1 r s EPARiiT /oN t Figure 41 - Bike Path 5' ewe MNE Page 72 - College Station Streetscape Study I/O pgAXW B/KE 5/oe) • A, /'iTH WHERE P1PT of :we ,eav[Ui4r 7e S//OVLDER /5 57X/PEP., - /y.UED, ANO APIRKED fo,C KCLOS /' - PREf 77AL B / -YGLE ' ✓SE RND C'Heee k$N/cte PLfK1/4 NoT PERM777.SO Figure 42 - Bike Lane with Divider the AASHTO Guide for Development of Bicycle Facilities. Bike Paths Typical layouts for bike paths is shown in Figures 39 and 40 taken from the AASHTO Guide for Development of Bicycle Facilities. Figure 41 shows a two -way bike path which is completely separated from auto traffic. Such a facility should have a minimum paved width of 10 feet and a desirable width of 12 feet plus a 2 feet graded width on each side. A width of 10 feet would allow maintenance and emergency vehicles to utilize the path. Bike Lanes. Bike lanes in the City of College Station must be developed as one -way facilities. Two way bike lanes are not permitted because: • They require unconventional turns at intersections. • They are conducive to having bicyclist go the "wrong way" and to weave across traffic to bike in the proper lane. • They require that bicyclist travel in a direction opposite the adjacent auto lane. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 t Typical bike lane design and layout is illustrated in Figures 42, 43, and 44. A one way bike lane at the curb requires a minimum of 5 feet measured from the face of the curb (Figures 42 and 43). A bike lane on a street with no curb and gutter should also be a minimum of 5 feet outside the auto lanes (Figure 44). Bike Routes. The placement of signing is the only physical design criteria that needs to be considered for bike routes. Bike route identification and directional signs will be located on identified routes as deemed appropriate by the City Traffic Safety Superintendent or his duly appointed representative. Bikeway System The master plan for the College Station Bikeway system is shown on Exhibit 14. Major elements of the plan are as follows: • Extension of the existing system into more recently developed subdivision of southern College Station utilizing bike routes along major thoroughfares such as Longmire, Deacon, Rio Grande, Welch, Rock Prairie Rd. • Future bikeway connecting neighborhood nodes east of the East By -Pass tying into Highway 30 to the north and Lick Creek Greenbelt to the Pass south. Drive Creek • future dedicated Bike Paths south. located in the Wolf Pen Creek, Bee Creek, and Lick Creek linear parks strategically connect adjacent neighborhoods into these linear parks. This would also allow emergency and service vehicular access into these areas. • Future Bike Path in the utility easement eat of the East By- Sr u_ -fie M/N B /KE LANE Figure 43 - Bike Lane on Curbed Street Marge vEH /c%f LANES connecting University to the north with Lick Wilderness Park to the n roc , �, co) I .I Figure 44 - Bike Lane on Non - Curbed Streets j 5M /N /3 /KE LANE College Station Streetscape Study - Page 73 ��z LEGEND � FUTURE BIKE PATH BIKE LANE H BIKE ROUTE FUTURE BIKEWAYS SCHOOLS PARKS /-c - LI — �1 /yY ,% ) - 1 f L1_ I I j - y _ •I II • r J � t- NORTH 0 1200 2400 4800 7200 • 4 1 BIKEWAYS PLAN COLLEGE STATION, TEXAS STREETSCAPE PLAN NEWMAN JACKSON BIEBERSTEIN, INC. PROTOTYPICAL PLANS OF STANDARD AREA TREATMENTS Prototypical plans have been developed for the following elements and conditions within the city: • City Portal - three types • Major Arterials • University Drive and Texas Avenue • Minor Arterials • Collectors • Streets crossing Floodplains and Parks • Typical Intersection Medi- ans • Special Intersections • Major Intersections City Portals As was mentioned previously, entries into the city have been identified as to importance and prototypical plans reflect this hierarchy. Type One Portals. Type One Portals are the most prominent entries to the city and are located at the intersection of Texas Avenue and Highway 6 By -pass, University Drive and the Highway 6 By -pass and Univer- sity Drive and FM 2818. The University Drive portals at the East By -pass and FM 2818 involve overpasses and large expanses of open space within which to develop the portal. It is recommended that the over- passes be utilized by placing on them a sign blade that announc- es the name of the City and points the direction to College Station. Plantings of large evergreens, masses of crape myrtle and wild flowers in large drifts complete the portal. Refer to Figure 44 and Exhibit 15. Because of the configuration of the Texas Avenue /Highway 6 interchange, a modified arrangement is recommended in which the sign blade occurs at ground level north of the inter- change. Planted with masses of evergreens and flowering trees this entry sign will come into view as the motorist passes beneath the overpass (north bound) or exits the by -pass (south bound). Refer to Figure 46. The Highway 30 (Harvey Road) and Highway 6 By -pass inter- section should also be consid- ered a Type One Portal because of the nearby location of Post Oak Mall. Because of the configuration of the overpass, signage design and placement should be similar to the Texas Avenue /Highway 6 portal.

Trees shall be planted in loose informal arrangements with a density of one tree per twenty -five (25) lineal feet of frontage. Two ornamental trees may be substi- tuted for one shade tree. Shade trees shall be selected from the group of trees listed in Figure 52. Special Arterials - University Drive and Texas Avenue University Drive and Texas Avenue public R.O.W. shall be planted with Water Oaks in the at a spacing of 60' -0 ". The Texas Avenue area fronting Texas A &M University shall be planted with Live Oaks. This formal planting is recommended to provide a visual unifying element in these areas of varied commercial uses. In areas where existing overhead utilities conflict with large canopy tree placement, smaller ornamental trees (tree yaupon) will be planted at 18' o.c. as a tempo- rary measure until the utilities can be relocated and the larger trees installed permanently.

In these instances it is recommended that the tree planting occurring on that particular thoroughfare be blended into the informal, natural feel of the parkland. Refer to Figure 56. This is particularly important in the case of the special streets of University and Texas Avenue where formal rows of oak trees have been recommended as street tree plantings. Where thoroughfares are wid- ened across floodplains, requir- ing expansion of bridges and culverts and necessitating re- moval of existing vegetation to complete construction, such areas should be re- vegetated using native material in masses that blend into the existing character of the remainder of the floodplain. Figure 57 - e _ I Figure 56 - Streets Crossing Floodplains and Parks Typical Intersection Medians In order to give an additional r.,- _asure of traffic separation as well as visual importance to specific intersections about the city, it is recommended that medians be introduced as shown by Figure 57.

OUT ; Res College Station Streetscape Study - Page 89 Special Intersections This study has identified two special intersections of major symbolic importance that should receive special design treatment of enriched paving. Texas Avenue and University Drive and Texas Avenue and George Bush Drive should receive CONCRETE PAYED+ (ggavArea+eP.t7T ') en catC. special emphasis because of their location with respect to the City and the University. As indicated in Figure 58 these two special intersections shall be paved with a heavy sandblast finish concrete with trowelled banding radiating from a center Page 90 - College Station Streetscape Study Figure 58 - Special Intersections of concrete pavers. A circular band of pavers ties the intersection together and provides visual relief from the heavy use of concrete. Special insets of fractured face concrete pavers will add detail and fur- ther visual relief to the intersec- tion, 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Major Intersections Other intersections have been identified about the city that, because of their significance, should receive special emphasis beyond the standard street intersection.

Northgate The Northgate area has been a traditional student "hang out" for many years with student oriented service establishments comprising the bulk of the land use, There is always activity in this area resulting in conflicts between pedestrians, vehicular traffic, and service vehicles. The recommended modifications Page 92 - College Station Streetscape Study to this area are illustrated on Exhibit 17 and address the following major concerns. • Organize and increase amount of parking. • Minimize conflicts between pedestrians, service vehicles and privately owned automobiles • Provide additional patron congregating points Major elements of the plan are: • Realignment and redevelop- ment of Patricia Street into a pedestrian oriented service corridor. Through traffic would be prohibited however vehicular access to parking areas at the rear of the Texas Aggie Book- store and Two Pesos Restaurant would be allowed. • Opportunity to create and develop rear entries into the business establishments and an enlarged patron congregating area at the rear of the three major night spots in the area. • Complete redevelopment of all parking between University and Church. It is recommended that the City take control of these areas and install meters or other appropriate control devic- es. All parking areas should be paved and striped. Recom- mended reconfiguration pro- vides for thirteen additional cars in the area. • Provision for clear avenue of pedestrian circulation from parking to business establish- ments. • Clustering of dumpsters into two specific locations to allow for more flexibility in developing amenities along Patricia Street. • Introduction of special lighting and other amenities such as site furniture and plant- ing that give character and identity to the zone. oiN Q VARSITY SHOP PATRICIA ST.

While the public green spaces east of Texas are gener- ally well maintained, the insta- bility of the commercial area has given the area an image of neglect and shabbiness. The plan for Eastgate (Exhibit 18) recaptures additional greenspace by eliminating the free right turn lanes off Texas and Walton. This facilitates the creation of a larger open space that is more in scale with the intersection. A grass berm five feet in height on either side of Walton provides additional focus to eastward views from the University. Additional plantings of large canopy trees and crape myrtle further define the area. A sidewalk traverses the area lined with benches and beds of groundcover and seasonal color. Banner staffs line the walk with banners that graphically relate to seasonal activities or special events. The Walton Drive median is redeveloped with low ground - cover and ornamental trees. Paving in the intersection of Texas and Walton is recom- mended to be enriched through the use of sandblasted concrete and concrete pavers as indicated on Exhibit 18. A circular form of concrete pavers and a five pointed star fill the intersection. College Station Streetscape Study - Page 95 Texas Avenue from University Drive to Dominik Drive This special project area fronts entirely on the east border of Texas A &M University and has for years contained a mixture of land uses from residential near the intersection of George Bush to public and institutional and retail /commercial. This variety of uses, coupled with a lack of screening controls on parking, has resulted in a mixed image along this important thorough- fare from pleasant on the south- ern end to harsh and cluttered on the north. The basic thrust of this pilot project has been to provide a streetscape treatment that unifies the images of the uses on the east side of Texas and provides an appropriate image to the University on the west. Refer to Exhibit 19. The following are the major recommendations of that plan: • Installation of Live Oak street trees on the east side of Texas at 60' -0" O.C. to unify the various land uses along the thoroughfare. Where R.O.W. width and existing conditions allow, this should be a double row to further reinforce this eastern edge. • Require consistent screen- ing of parking with plant mate- rial within the commercial and public /institutional land uses. • Provide a sidewalk along the east side of Texas for pedes- trian only. It is recommended that this walk be at least six (6) feet in width but that final width be determined by anticipated pedestrian volume. • Relocate all utility lines behind the commercial estab- lishment in alleys or easements, or place them underground. • Redevelop Eastgate Park into an important public focal space at the Main Entrance to Texas A &M University. • Encourage TDHPT to minimize southbound left turn movements along Texas. • Encourage Texas A &M University to develop a hike/ - bike trail in an informal free form alignment along the east frontage of the campus as part of the east edge renovation outlined in the Campus Master Plan dated April 1990. College Station Streetscape Study - Page 99 City Entry - University and FM 2818 This pilot project provides the first image of entry to the City for those motorists approaching from the west and from the north and south utilizing the west by -pass. The basic concept of this pro- ject has been to utilize the overpass and its surroundings as much as possible in developing this portal so that the scale of the entry is appropriate related to its surroundings. Refer to Exhibit 15 for this project. The major recommendations of this project are: • Placement of sign blades on the overpass announcing the name of the City and which also graphically point the direction to College Station. • Planting masses of ever- greens and ornamental trees to provide further definition of this space as a portal. • Planting of broad drifts of wildflowers to add color and scale to this portal.

The actions required to achieve the implementation of the pro- ject are equally impacting on the City, its economic context, and the administrative policies and process now controlling the development along thoroughfare corridors, The action of this study alone implies an admini- strative understanding of the need to alter the quality of the streetscape environment. Pub- lic /private committee reviews of this study indicates their recog- nition of the significance of this type of improvement to their operations and property value, Throughout the design process, care was given to not only installation costs, but to the ongoing cost and ease of main- tenance. Thus much of the proposed design may be imple- mented through the ongoing redevelopment process. How- ever, should the timing for implementation be advanced to take advantage of today's lower costs, more extraordinary mea- sures would be essential, Funding Options Landscape Cost Sharing Program. Of vital importance to the implementation of streetscape improvements is the identification of appropriate funding sources. Although hampered by process- ing time and a loss of project control, the State Department of Highways and Public Transpor- tation (SDHPT) has a Land- scape Cost Sharing program that could provide a portion of the funding of improvements along the state highways that pass through the City. This program classifies land- scape projects as: • Highway Landscape Pro- jects - Those projects which, after installation, give the visual impression of belonging to the highway route rather than being an extension of adjacent private property. The State will fund up to 50 percent of the total cost of this type of develop- ment. • Pedestrian Landscape Pro- jects - Those projects which give the impression of being an extension to adjacent private or public property outside the highway corridor. The State will fund up to 50 percent of the cost of the material only, These types of projects are subject to other restrictions based on location, nature of the design, etc. City portals at the Highway 6/ East By- Pass /Texas Avenue interchange, East By -Pass/ University Drive, and FM 2818 /University Drive should be eligible as Highway Land- scape Projects while the balance of the streetscape improvements to University and Texas (i.e. Northgate, Eastgate, and Texas Avenue) would be classified as a Pedestrian Landscape Project. Every effort should be made to facilitate public /private coopera- tion in implementing this plan. In many instances, the speed with which the private sector can proceed will reduce a pro- ject's cost by minimizing unnec- essary delays. On the other hand, the authority of local government may permit the accomplishment of certain improvements which cannot be completed in the private sector. Evidence of increases in eco- nomic value due to streetscape improvements exists now in other cities which have imple- mented a plan. Dallas, Addi- son, the Las Colinas section of Irving, Plano, and Coppell all claim varying degrees of in- crease of economic value due to the positive effects of a street - scape program. Clearly this evaluation should focus not only on the value to the automobile user and the pedestrian user, but also the value to the com- munity at large, to the pedestri- an and to the abutting property owner. The streetscape redevelopment College Station Streetscape Study - Page 107 must be viewed as an opportuni- ty to achieve design continuity with a focus on economy and efficiency of maintenance. Clearly it offers the chance to eliminate the clutter of the present environment, to facili- tate new projects, to reassure citizenry and the property own- ers of the potential return value of their investment. Capital Improvement Programs. This is the primary avenue of funding capital improvements for the City. Development under this method might be two to three years away. The proposed bond program might provide full or matching funds, depending on the type of program. Since bonds required voter approval, it will be essential to gain support of the citizenry for this type of improvement program. Candidate projects for a bond issue could be: • Northgate Improvements • Portals to City • Eastgate Park Joint Development. The City should continue to explore ways to implement a project jointly with a developer of a large tract bordering a potential streetscape project such as University Drive. Potential projects to consider with TAMU are: Page 108 - College Station Streetscape Study • Eastgate Park • Intersection Improvements at Texas Ave. and George Bush Drive; Texas Ave. and University Drive and Wellborn Road and George Bush Drive. Non - profit Fund. Under the direction of either the private or public sector, a non - profit fund could be set up to receive funds from concerned individuals, organizations or institutions which would be directed toward streetscape improvements within the City. By having an ongoing administrative mechanism, donations to such a fund could be actively sought and encouraged on a regular basis. Reimbursement to Private Sector. There are established precedents in other cities to indicate that where a private developer wished to precede the City in developing in the public R.O.W. according to the prescribed guidelines, the City with guarantee return of investment when funds become available. Incentive Zoning. Though this avenue is open to the City currently, careful control is needed to assure the right exchange of value. The intent of the program is to allow developers additional flexibility in their projects, but only if additional streetscape amenities are included in their plans. Here the City could also require a percentage of construction costs for art objects in the trade -off program. This method gas been used in other cities. however the demands and guidelines for the streetscape amenities were not specific enough to guarantee quality development for pedestrian usage. The City needs to carefully evaluate the recommendations to assure compliance with the intent to gain significant pedestrian benefit. Tax Increment Financing. Other cities have used this financing method with success on various improvement projects, but it has yet to be applied to a streetscape program. It involves designating a certain area as a tax increment district. Tax revenues from that area which flow to the taxing bodies are frozen at the current level for a specified number of years. As new development take place within that district, the additional tax revenue generated by those projects is allocated to pay off bonds that were issued to finance public improvements in the district. In this manner, both the public and private sectors and the pedestrian benefit, and the streetscape is enhanced in a coordinate manner at the present time. Special Assessment District. This idea can take many forms, either as a governmental unit or as a private unit. The intent of the unit is to recognize the common goals, the unique requirements and special treatment required to maintain desirable levels of improvements. The district may be set up for capital improvements or simply for the purpose of funding special operating requirements. Existing Ordinance Re- view and Revisions The success of the Streetscape Plan and Guidelines and criteria will, in a large part, be determined by how well City of College Station policies and ordinances are written to encourage and direct their implementation. The ordinances ought to reflect the philosophy, and the goals and objectives of the City Leadership regarding the image of its thoroughfares and commercial areas. To that end the sections of the existing Zoning Ordinance pertaining to Parking and Landscaping were reviewed and the following revisions /additions to the ordinance are recommended: 1. Parking requirements stipulate a minimum eight foot (8') raised buffer between public R.O.W. and parking. No other criteria or guideline addresses buffer strips or landscape setbacks. This tends to encourage parking out to property lines in commercial areas. It is recommended that the landscape reserve (buffer strip) requirements at site perimeters be increased from 8 foot minimum to 24 foot minimum at major and minor arterials. Existing trees located in these landscape reserves will be required to be preserved and areas of reserves that have no trees will be landscaped as follows: • Major Arterials - One shade tree (min 4" cal.) per 25 lineal feet of landscape reserve. Two ornamentals may be substituted for one shade tree. These trees should be loosely spaced in an informal arrangement. • Texas Avenue and University Drive - Place Water Oaks (min. 4" cal) at 60 feet on center. Where overhead utilities conflict, small trees (tree yaupon, minimum 8' -10' ht.) will be planted until utilities are placed underground. • Minor Arterials - Provide one shade tree (min. 4" cal.) or two ornamental trees per 32 lineal feet of landscape reserve. In return, lessen the requirement for interior parking area islands and related landscaping as further explained below. It will be a requirement to attain 300 points for every 50 lineal feet of landscape reserve that exists on a property. 2. It will be a requirement to screen surface parking from major and minor arterials through the use of the following: • Planting Screens • Berms • Structural Screens Parking requirements also dictate specific guidelines concerning placement and configuration of interior parking islands to encourage landscaping and break up large expanses of paving. It is recommended that more flexibility be allowed in parking area design and landscaping by modifying this requirement in the Parking Requirements section of the Zoning Ordinance as outlined below: • To give some additional control over tree densities in parking areas, require parking spaces to be located no further than 75 feet from the trunk of a College Station Streetscape Study - Page 109 large canopy tree. • In lieu of requiring a raised island of 360 square feet for every 15 spaces on interior parking rows allow a raised tree island of 36 square feet (6' by 6'). 3. Require screening of off - street loading areas, dumpster locations, and utility connec- tions from public streets and residential adjacencies. 4. Drop the requirements and 'Points - Awarded' for shrubs and groundcover. 5. Incorporate into landscape ordinance a set of soil' require- ments that stipulate minimum acceptable standards for soil depths, dimensions, and basic composition. 6. Require an automatic sprin- kler system for all required screening and street tree instal- lation. Recommend 100 feet minimum spacing rather than 150 feet for hose connections. 7. Allow point credit for special amenities: • Use of enhanced paving at vehicular paved areas • Use of permeable enhanced paving • Use of enhanced paving at pedestrian paved areas Page 110 - College Station Streetscape Study • Use of plazas, fountains, ponds, and seating areas. 8. Require for use of street trees that: • Extend along a minimum of 80% of the total street frontage of a lot. • Are spaced no more than 60 feet apart. • Rework paint allocation on existing and new trees in order to encourage existing tree pres- ervation.

Current ordinance requires a min. 4.5' barricade and grants points in a graduating scale downward based on size of tree. Revision would require a minimum barricade of 1' for every I' of tree caliper. Points awarded would be based on tree size. 2. Current ordinance requires a 3.5' cal. min. Revision would make minimum size 4' cal. 3. Use of tree smaller than 4' would require special approval by Zoning Official and should only be proposed when conditions preclude use of larger trees. 4. 300 points would be awarded when at least 25 percent of all outdoor vehicular pavement area on the lot consists of enhanced paving. 5. 50 points is awarded for each one percent increment of lot area covered by publicly accessible special pedestrian facilities and features such as plazas, covered walkways, fountains, lakes and ponds. two streets or the intersection of driveway or alley with a street. The current requirements call for a setback of twenty -feet from intersecting property lines. Proposed modification would measure the setback from curb or paving intersection points with a 20' setback for street /driveway /alley and a 45' setback for street intersections. Streetscape Maintenance Responsibilities Unless there is a commitment of both the public and private sector to maintain the improvements recommended by this study, then the long term benefit to the citizens by the program are never going to by realized. In that regard, it is important to outline maintenance responsibilities of the streetscape elements clearly so that both public and private sector understand their respective responsibilities. The following are recommendations as to the general responsibilities of each: Public Responsibilities • Maintain all improvements (softscape and hardscape) occurring in public parks (i.e. Eastgate Project, etc.) and in medians. • Maintain all light fixtures, banners, and other special amenities occurring on City property. • Maintain all softscape improvements and State Highway interchanges for minimum of 24 months. • Maintain all special amenities (i.e. portal graphics, special paving, benches, irrigation systems, etc.) on State R.O.W. Private Responsibilities • Maintain all softscape and hardscape improvements including irrigation occurring within the specific properties and within the public R.O.W. bordering the specific properties. Required landscaping must be maintained in a healthy, growing condition at all times. The property owner is responsible for regular weeding, mowing of grass, irrigating, fertilizing, pruning, and other maintenance of all plantings as needed. • Maintain all required parking and dumpster screening. • Maintain all interior lighting, signage, and special amenities.

Natural vegetation consists of scrubby hardwoods and bunchgrass. Crusty soil occuring in gently sloping upland. Moderately fertile and responds well to fertilization. Similar in profile to Cc, but more susceptible to erosion due to thin surface layer. Low permeability and promotes rapid runoff and resultant erosion. Light colored acid soil of poor productivity. Low natural fertility, but responds well to fertilizers. Droughtiness restricts productivity. Thinner surface soil than Ea, unsuitable for cultivation and poor for pasture. Its most practical use is woodland pasture. Gray, slightly acid clay loam occuring in floodplains and along local streams made up of sediments washed from nearby uplands. Similar to Ga occuring in small irregular areas that are flooded once or twice a year in Spring. High natural fertility. Consists of areas severely cut by gullies; has no economic value and most areas have no vegetation. Fertile, moderately productive clayey soil occuring in uplands. The soil erodes easily and its natural fertility is moderately too high. Moderately fertile, crusty, claypan soil occuring throughout the area. Since compact claypan is impervious to water plants scoffer during the hot, dry weather. Similar to Lc except much more susceptable to erosion. Similar to Lf with low natural fertility and tendancy for droughtiness. Occurs mostly in southern parts of the area. Highly erodable claypan soil unsuitable for cultivation. Low productivity, but supports shade and ornamental tree growth. Productive, well drained, bottomland soil occuring along small local streams. Native vegetation is dense cover of oak, elm, hackberry, and ash. Pale brown, slightly acid fine sandy loam of moderate to low productivity. Native vegetation consisting of scrubby, hardwood forest. Pale brown, slightly acid loamy fine sand responsive to fertilizers and good management. Drought resistant. Moderately productive loamy soil occuring in upland areas. Natural fertility is moderate and soil leans toward droughtiness. The list of plant materials, located in the Appendix of this report, should be used in future development. The plant materials included should comprise the major components of landscape development. Since these materials serve a specific function, any variance would tend to weaken the overall design intent. The plant materials suggested are only those which are considered native or which have proven satisfactory for the College Station area. Careful consideration has been given to selection of plant materials which are considered easy to maintain, generally free of insects and disease, and relatively hardy for this area. Plant materials shown in the list should also be considered for private development, but should not be viewed as the only plants acceptable for use.
