HEC -RAS Input and Output 3 4 1.0 LOCATION The project site is approximately 20 .63 acres and is located at the east corner of Luther Street and Harvey Mitchell Parkway (a .k.a . F.M. 2818), approximately one half mile southeast of the intersection of George Bush Drive and Harvey Mitchell Parkway. As well, the site is approximately 1.5 miles from the Texas A&M University main campus. The site is within the City of College Station Corporate Limits, Brazos County, Texas (Grid No. N-37). The current land use is agricultural/open space with at least one , possibly two, detached single family dwelling units located upon the property . The proposed land use is Multi -Family, and can be better seen on the attached site location map and aerial photograph as shown in Exhibits 1 and 2 , respectively . The site is located on the "Wellborn" USGS 7 .5 minute Quadrangle sheet. The site adjoins a small waterway, which is a tributary to White Creek, a primary drainageway, which is a tributary of the Brazos River. No portion of the subject tract is located within the Special Flood Hazard Area (100 year floodplain) according to the Flood Insurance Rate Map for Brazos County, Texas, Map Nos. 48041C0181C and 48041C0182C, Community No. 480083, Panel Nos . 0181C and 0182C, effective July 2 , 1992 (Exhibit 5) 2.0 PROPERTY CHARACTERISTICS The current land use for the subject tract is agricultural, with one or two single family dwellings located upon the property. The 20.63 acre tract can be described as slightly vegetated with flat to moderately steep slopes . Vegetation mostly consists of post oak , and other hardwoods, located around the vicinity of a natural waterway through the property. Slopes across the tract range from 2% to 5%, draining toward the waterway located along the front third of the property. Accord ing to the Soil Conservation Service "Soil Survey of Brazos County , Texas ," there are two predominant soil types located on the subject tract. Both soil types consist of various sandy loam layers at the surface , with more clayey soils below the sandy loam. These layers of clay are typical of most clay types found in the area with very high shrink-swell potential. The majority of the site consists of the Tabor Series (Ta) fine sandy loam , and the Lufkin Series (Lf) sandy loam . The s ubj ect tract is bounded to the northwest by Luther Street, and to the southwest by Harvey Mitchell Parkway . Most of the property on the opposite sides of these roadways is currently owned by Te xa s A&M Un iv ersity, and is not expected to be sold or developed in the near future . However, G:\124-14\DOCS\drngrpt.wpd Page 1 of 5 April 18, 2000 there are two vacant, undeveloped, privately owned tracts located on the opposite side of Harvey Mitchell Parkway. Currently, the TAMU property is undeveloped, and is being used for agricultural research purposes for the university. Adjacent property to the northeast is currently owned by Sigma Alpha Epsilon fraternity, and is currently being developed for their fraternity house . Adjacent to that tract is an existing multi-family development, Melrose Apartments. Property to the southeast is currently an undeveloped , wooded, 6 .0 acre tract owned by Raymond Gorzycki . No plans are currently in the review process for this tract. A small waterway, which is a tributary to White Creek, drains through the front third of the property . This waterway originally drained a significant drainage area, up to Jones Butler Road, however, since the construction of the Melrose development, a significant portion of the original drainage area has been diverted into a detention pond located at the south corner of the Melrose development, which discharges into the waterway Walden Pond is located on . Secondary drainage includes the waterway through the subject tract, and various storm sewer systems that will drain into the waterway from the proposed development. Offsite drainage includes approximately 20 .9 acres associated with Luther Street R.O.W ., the SAE Fraternity House , the outparcels and future Phase Two of the Melrose development, located north of the subject tract. Approximately 9.94 acres of the 20.9 acres will drain directly into Luther Street. A 36" and 24" storm sewer with three 10' inlets will be constructed to drain the 9.94 acres . The remaining 10.97 acres is a~sociated with the Fraternity House, and drains to a low point located along the northeastern property line of the subject tract. A 30" storm sewer and inlet will be constructed to the low point to drain the 10.97 acres. All drainage ca lculations were performed for fully developed , un-detained conditions for the 100 year storm . Though detention is being provided for the Fraternity House, and the Phase Two plans for Melrose indicate that a detention pond is proposed upon development of that tract, for purposes of sizing storm sewers and inlets, it was assumed that detention was not provided. The subject tract w ill be developed as a student housing , multi-family development consisting of fifteen residential buildings and one clubhouse /leasing office, with a total of 324 dwelling units . Amenities will include a swimming pool, a basketball court and two sand volleyball courts . G :\124-14\DOCS\drngrpt.wpd Page 2 of 5 April 18 , 2000 3.0 DRAINAGE DESIGN CRITERIA Currently, no drainage studies exist for the secondary waterway through the subject tract. As stated previously, a significant portion of the natural drainage area has been diverted into another drainage area , and therefore peak discharges into the waterway have been reduced. However, due to the proposed development of the subject tract, discharges will be increased due to the increase in impervious cover. Private drainage easements will be dedicated for the natural waterway, and those storm sewer systems collecting offsite drainage. All drainage systems will be privately maintained , with the exception of the system that drains Luther Street. Offsite drainage calculations for the Luther Street storm sewer system, as well as the analysis of the existing 60" culvert beneath FM 2818, and for purposes of calculating a 100 year floodplain for the water way through the site, were calculated for the 2-, 5-, 10-, 25-50-and 100-year storms . Storm sewer sizes were calculated with Manning's equation, with a Manning's n value of 0.014 . All pipes are sized to convey the 100 year storm discharges with out surct 1arging. The Luther Street storm sewer will traverse a portion of the proposed development, and ultimately discharge into the waterway. This storm sewer is located within a 15' drainage easement. The total drainage area to the existing 60" culvert is approximately 46 .34 acres , which develops a fully developed, undetained 100 year discharge of 211 cfs. A HEC-RAS computer model was developed to calculate wate~ surface elevations for the waterway through the site, and to delineate a 100 year flood plain. As shown on the Floodplain Delineation Map, the floodplain does not affect any proposed build ings or parking areas . As well, all wastewater manholes are located outside the floodplain . The HEC-RAS input and output are included herein . The HEC-RAS model begins downstream of the 60" culvert , and therefore includes the culvert in the analysis . Based on conversations with City staff, the subject tract would not be required to provide onsite detention provided conveyance of stormwater flows is available through the 60" RCP culvert beneath Harvey Mitchell Parkway . Based on the above me nti oned offsite calculations for the 46.34 acres , the 100 year peak discharge is 211 cfs to the culvert . Based on the HEC-RAS outpu~. the calculated headwater elevation on the 60" RCP is 292 .53, while the road elevation is 302 .5 thus prov idin g approximately 10 .0 feet of freeboard . Therefo re, the culvert has adequa te capac ity to convey un-detained flows from the subject tract. G:\124-14\DOCS\drngrpt.wpd Page 3 of 5 April 18 , 2000 Onsite drainage calculations for the storm sewer system arid inlet designs were calculated using the Rational Method , with a 10 minute time of concentration. Peak discharges were calculated for the 2-, 5-, 10-, 25-50-and 100-year storms . These calculations are included on the drainage area map (Exhibit 3). Storm sewer sizes were calculated with Manning 's equation , with a Manning 's n value of 0.014. All pipes are sized to convey the 100 year storm discharges with out surcharging. Storm sewer outfalls will consist of headwalls with energy dissapators and rock rip-rap to minimize erosion at the outfall. Storm sewer lines will be constructed with Class Ill RCP for pipe sizes 18" and larger, and SOR 26 PVC for 12" and 15" pipe sizes. The contractor will be allowed an alternate bid item to use High Density Polyethylene (HOPE) pipe in lieu of the materials mentioned above . This pipe is corrugated on the outside, with a smooth wall on the inside, and therefore has comparable structural and hydraulic characteristics as RCP and PVC. Surface drainage will consist of sheet flow and concentrated flow along drainage swales and curb gutters . Grassed swales around buildings are graded with a minimum slope of 2 .0%, and paved areas with concentrated flow are graded with a minimum slope of 1.0%. All paved areas will drain to curb inlets located throughout the parking lot, and grassed and landscaped areas will drain to area grate inlets provided throughout those areas. All stormwater runoff from the subject tract w ill be collected and discharged into the natural waterway. 4.0 SUMMARY AND CONCLUSION The subject tract is located on the east corner of Harvey Mitchell Parkway and Luther Street , opposite Texas A&M property. The proposed development consists of 324 multifamily units designed to accommodate student housing , with all required parkin~ and drives , and amenities such as a clubhouse, swimming pool , basketball court and volleyball courts . Conveyance for stormwater runoff will be provided by constructing onsite storm sewer systems that will discharge into a secondary waterway that runs through the site . Offsite flows will be conveyed to the waterway v ia storm sewer systems . All systems are designed to convey the 100 year storm witho~t surcharg ing the system . Conveyance through the 60" RCP culvert beneath Harvey Mitchell Parkway is available for the fully developed , 100 year storm, and therefore detent ion is no t required.

Hydro logic I Hydraulic Calculation for 60" Culvert Page 1 1 2 4 1.0 LOCATION The project site is approximately 20.63 acres and is located at the east corner of Luther Street and Harvey Mitchell Parkway (a.k.a. F.M. 2818), approximately one half mile southeast of the intersection of George Bush Drive and Harvey Mitchell Parkway . As well, the site is approximately 1.5 miles from the Texas A&M University main campus. The site is within the City of College Station Corporate Limits, Brazos County, Texas (Grid No. N-37). The current land use is agricultural/open space with at least one, possibly two , detached single family dwelling units located upon the property. The proposed land use is Multi-Family, and can be better seen on the attached site location map and aerial photograph as shown in Exhibits 1 and 2, respectively . The site is located on the "Wellborn" USGS 7 .5 minute Quadrangle sheet. The site adjoins a small waterway, which is a tributary to White Creek , a primary drainageway, which is a tributary of the Brazos River. No portion of the subject tract is located within the Special Flood Hazard Area (100 year floodplain) according to the Flood Insurance Rate Map for Brazos County , Texas, Map Nos. 48041 C0181 C and 48041 C0182C, Community No . 480083, Panel Nos . 0181 C and 0182C , effective July 2, 1992 (Exhibit 5) 2.0 PROPERTY CHARACTERISTICS The current land use for the subject tract is agricultural , with one or two single family dwellings located upon the property. The 20 .63 acre tract can be described as slightly vegetated with flat to moderately steep slopes . Vegetation mostly consists of post oak, and other hardwoods, located around the vicinity of a natural waterway through the property. Slopes across the tract range from 2% to 5%, draining toward the waterway located along the front third of the property . According to the So il Conservation Service "Soil Survey of Brazos County, Texas ," there are two predominant soil types located on the subject tract. Both soil types consist of various sandy loam layers at the surface, with more clayey soils below the sandy loam. These layers of clay are typical of most clay types found in the area with very high shrink-swell potential. The majority of the site consists of the Tabor Series (Ta) fine sandy loam, and the Lufk in Series (Lf) sandy loam. The subject tract is bounded to the northwest by Luther Street, and to the southwest by Harvey Mitchell Parkway . Most of the property on the opposite sides of these roadways is currently owned by Texas A&M University, and is not expected to be sold or developed in the near future. However, G:\124-14\DOCS \EngrptSP .wpd Page 1 of 4 April 18, 2000 there are two vacant, undeveloped, privately owned tracts located on the opposite side of Harvey Mitchell Parkway . Currently, the TAMU property is undeveloped, and is being used for agricultural research purposes for the university. Adjacent property to the northeast is currently owned by Sigma Alpha Epsilon fraternity, and is currently being developed for their fraternity house . Adjacent to that tract is an existing multi-family development, Melrose Apartments. Property to the southeast is currently an undeveloped , wooded, 6.0 acre tract owned by Raymond Gorzycki. No plans are currently in the review process for this tract. A small waterway , which is a tributary to White Creek, drains through the front third of the property. This waterway originally drained a significant drainage area , up to Jones Butler Road , however, since the construction of the Melrose development, a significant portion of the original drainage area has been diverted into a detention pond located at the south corner of the Melrose development, which discharges into the waterway Walden Pond is located on. Secondary drainage includes the waterway through the subject tract, and various storm sewer systems that will drain into the waterway from the proposed development. Offsite drainage includes approximately 5.5 acres associated with Luther Street R.O .W ., and the outparcels located north of the subject tract. The 5.5 acre drainage area will be collected via a proposed curb inlet located within Luther Street, that will discharge into the waterway v ia a storm sewer system. This storm sewer is to be constructed with the Luther Street Improvements construction plans that are currently being reviewed . As well, Lots 1 and 2 of the Melrose development, that portion south of the existing apartments (11 .9 acres), will drain through the waterway via a 30" storm sewer line to be stubbed to their property. Currently , Lot 1 is under construction with a fraternity house . Construction plans for that development indicate a detention pond to be located along the northern boundary line of the subject tract. The subject tract will be developed as a student housing, multi-family development consisting of fifteen residential buildings and one clubhouse /leasing office, with a total of 324 dwe lli ng un its . Amenities will include a swimming pool , a basketball court and two sand volleyball courts . 3.0 DRAINAGE DESIGN CRITERIA Current ly , no dra inage studies exist for the secondary waterway through the subject tract. As stated previously , a significant portion of the natural drainage area has been diverted into another drainage area, and therefore peak discharges into the waterway have been reduced . However, G :\ 124-14\DOCS\EngrptSP .wpd Page 2 of 4 A pri l 18, 2000 due to the proposed development of the subject tract, discharges will be increased due to the increase in impervious cover. Private drainage easements will be dedicated for the natural waterway, and those storm sewer systems collecting offsite drainage . All drainage systems will be privately maintained. Drainage calculations for the storm sewer system and inlet designs were calculated using the Rational Method, with a 10 minute time of concentration . Peak discharges were calculated for the 2-, 5-, 10-, 25-50-and 100-year storms. These calculations are included on the drainage area map (Exhibit 3). Storm sewer sizes were calculated with Manning 's equation, with a Manning 's n value of 0.014. All pipes are sized to convey the 100 year storm discharges with out surcharging. Storm sewer outfalls will consist of headwalls with energy dissapators and rock rip-rap to minimize erosion at the outfall. Storm sewer lines will be constructed with Class 111 RCP for pipe sizes 18" and larger, and SOR 26 PVC for 12" and 15" pipe sizes . The contractor will be allowed an alternate bid item to use High Density Polyethylene (HOPE) pipe in lieu of the materials mentioned above . This pipe is corrugated on the outside , with a smooth wall on the inside, and therefore has comparable structural and hydraulic characterist ics as RCP and PVC. Surface drainage will consist of sheet flow and concentrated flow along drainage swales and curb ·gutters. Grassed swales around build ings are graded with a minimum slope of.2.0%, and paved areas with concentrated flow are graded with a minimum slope of 1.0%. All paved areas w ill drain to curb inlets located throughout the parking lot , and grassed and landscaped areas will drain to area grate inlets provided throughout those areas . All stormwater runoff from the subject tract w ill be collected and discharged into the natural waterway . Based on conversations with City staff, the subject tract would not be required to provide onsite detention provided conveyance of stormwater flows is available through the 60" RCP culvert beneath Harvey Mit chell Parkway . Hydrologic ca lculations for the drainage area to the culvert are provided for the fu ll y developed , un-detained 100 year storm , utilizing the SCS method with HEC-1. As well , hydraulic calculations for the culvert are provided utilizing t he TxDOT THYSYS Culvert program , and ver ify ing the results w ith a TxDOT nomograph . The 100 year peak discharge is 338 cfs to the culvert . The calculated headwater elevation on the 60" RCP is 297.91, while the road elevation is 302 .5 thus providing approximate ly 4 .5 feet of freeboard . The Tx DOT nomograph computes a headwater elevation of 298 .32, thus providing 4.2 feet of freeboard . Therefore , the culvert has adequate capacity to convey un-detained fl ows from the subj ect tract. These calculat ions are prov ided in Appendix C and a drainage are map is shown in Exhibit 4. G :\ 124-1 4\DOCS\EngrptSP . wpd Page 3 of 4 A pril 18, 2000 4.0 SUMMARY AND CONCLUSION The subject tract is located on the east corner of Harvey Mitchell Parkway and Luther Street , opposite Texas A&M property. The proposed development consists of 324 multifamily units designed to accommodate student housing, with all required parking and drives , and amenities such as a clubhouse , swimming pool, basketball court and volleyball courts. Conveyance for stormwater runoff will be provided by constructing on site storm sewer systems that will discharge into a secondary waterway that runs through the site . Offsite flows will be conveyed to the waterway via storm sewer systems . All systems are designed to convey the 100 year storm without surcharging the system . Conveyance through the 60" RCP culvert beneath Harvey Mitchell Parkway is available for the fully developed , 100 year storm, and therefore detent ion is not required . I hereby certify that t his report for the drainage design of Fairfield at Luther Street -Mu lti-Family Site Plan was prepared by me in accordance with the provisions of the City of college Station Drainage Policy and Design Standards for the owners thereof.

Please submit the actual construction set(s) to be stamped. This should includeEC-0 , Sheet 3/39 (EC details), and any other grading sheet(s) you wish to include. 2 . Th is project will need three development permits: 1) apartment site , 2) street construction , and 3) lift station. Each will need an erosion control plan . Sheet EC-0 9/39 is the approved erosion control plan for the apartment site Build ing Permit. Each permit can be separated into "Clearing and Grading" and "Full" Development Permit. A Clearing and Grading Permit will be issued for the apartment phase when the construction plan sets have been stamped approved. 3 . There is still one issue yet to be addressed. The culvert , which is downstream of this site and crosses FM 2818, contained 2'-3' of silt the last time it was checked. Since this project is depending on drainage through th is culvert , please contact TXDOT to correct this problem . TXDOT contact information is Neal Munn or Ronnie Waller at 979-778-8054.

December 14, 1999 David Wright Fairfield Residential, L.L.C. 2045 N . Hwy 360, Ste. 250 Grand Prairie, Texas 75050 HJN 990335 Re: 18-acre Luther Street site, College Station, Brazos County, Texas Dear Mr. Wright: Per your request, Horizon Environmental Services, Inc. (Horizon) has performed an investigation of existing state records and a preliminary site reconnaissance for the subject site on 23 November 1999, with respect to the possible occurrence of federally or state-listed threatened or endangered species, the potential for cultural resource deposits, and jurisdictional waters of the US. The subject site is located in the central portion of Brazos County, Texas, within the City of College Station. More specifically, the site lies along Luther Street, north of SH 2818 (Figure 1 ). The subject site currently consists of partially wooded and previously cleared oak woodlands, which have historically been utilized for rural residential, as well as swine and cattle production activities. The subject site is bound to the west by West Luther Street; to the north and east by rural residential; and to the south by FM 2818. Current use of the subject site is rural residential and agricultural. The "take" of a federally listed, threatened or endangered species is prohibited by Section 9 of the Endangered Species Act of 1973. A "take" is defined as the killing, harassment, or alteration of essential habitats used by a protected species. The only threatened or endangered species listed for Brazos County is the Navasota Ladies' Tresses (NL T) (Spiranthes parksil). Records at the Texas Parks and Wildlife Department Biological Conservation Data Systems were investigated for the occurrence of previously recorded threatened or endangered species on or within 1 .0 miles of the subject site which occur within Brazos County. No previously recorded occurrences were discovered. Mr. Shannon Dorsey, a biologist with Horizon, conducted a habitat assessment survey of the subject site to determine if soils and habitat suitable for utilization by the NL T was present. Although a natural defined drainage area does exist on the site, it 990335non-astm 1 CORPORATE OFFICE : P.O . Bo x 162017 • Austin , Texas 78716 • 2600 Dellana Lane, Suite 200 • Austin , Texas 78746 (512) 328-2430 • FAX (512) 328-1804 • http ://www.ho ri zon -esi.com Hor7!"' ENVIRONMENTAL SERVICES, INC . was determined that no suitable habitat for the NL T exists on the subject s ite due to the lack of fine sandy soils in the vicinity of the drainage area which are utilized by Spiranthes sp . No NL Ts were observed on the subject site although this is the time of the year in which Spiranthes species are blooming. Archival research conducted via the Internet at the Texas Historical Commission's Texas Archeo/ogica/ Sites Atlas web site showed 7 archaeological sites within a 2 -mile radius of the subject site. Differentiated by type, the sites are classified as follows: 2 prehistoric lithic scatters; 2 prehistoric lithic procurement areas ; 1 multicomponent site containing both prehistoric and historic material; 1 historic cemetery; and 1 s ite for which there were no records on file . No recorded sites were located within the subject site, and no properties listed on the National Register of Historic Places (NRHP) or the list of State Archaeological Landmarks occur on or adjacent to the subject site . Archeological sites are commonly found on upland areas and alluvial terraces along stream channels. An unnamed tributary runs through the eastern portion of the subject site suggesting a possibility of locating cultural resources within the site's perimeters. Therefore, if any federal agency permits (including nationwide permits), federal loans , or loan guarantees are required for development of the subject site, additional efforts to identify and assess potential impacts to cultural resources may be required by the permitting agencies under Section 106, 36 CFR § 800, and the implementing regulations for compliance with the National Historic Preservation Act . Areas subject to jurisdiction under Section 404 of the Clean Water Act are commonly referred to as "wetlands"; however, "wetlands" are actually subsets of areas subject to jurisdiction and potential permitting constraints. The overall term used in the regulations is "waters of the US", which includes wetlands; all surface tributary streams with a defined channel; all major streams and rivers, lakes, and most ponds; and occasionally artificial features such as ditches or abandoned borrow pits. Jurisdictional wetlands are defined by federal regulations as areas inundated or saturated by surface or groundwater at a frequency and duration sufficient to support and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions (EPA, 40 CFR 230 .3). Field reconnaissance of the subject site confirmed the presence of an unnamed tributary traversing the central portion of the subject site. Any impacts to the defined areas of this natural drainage feature would be subject to jurisdiction by the COE. The total acreage of jurisdictional areas does not exceed 3 acres and could be permitted under existing Nationwide Permits. It should be noted that Nationwide Permit 26 (NWP 26), under which many of the proposed project's actions would be covered , is 9903 35non-astm 2 @ PR INT ED ON RE CYCLED PA PER HoriJ..oo ENVIRONMENTAL SERVICES, INC . slated for replacement by several new NWP early next year. The requirements of the proposed NWPs are more restrictive than the existing permit and will most likely require additional perm itting action and agency correspondence as well as mitigation efforts . However, assuming an average jurisdictional width of 5 feet to the ordinary high water mark (OHWM), and a total length of approximately 1000 feet, the total acreage of impact would be approximately 0.12 acres and would not require pre- construction notification or mitigation efforts in coordination with the COE . A post- construction report would be required to satisfy the requirements of the NWP. If significant portions of the defined drainage area are to be disturbed during the proposed project, a detailed site plan identifying these areas should be provided to assist in the exact calculation of acreage of impact so that permitting actions may be pursued through the COE . No other areas subject to regulation by the COE were identified on the subject site. SUMMARY It is our opinion that the subject site does not exhibit habitat characteristics suitable for utilization by any threatened or endangered species which occur in Brazos County and also presents a low probability for the occurrence of significant cultural resource deposits. Impacts to the jurisdictional drainage area would be authorized by NWP 26 and may not require pre -construction notification to the COE or m itigation for impacts under 1 /3 acre if initiated prior to the replacement of the current NWP 26 . The COE does require post construction within 30 days of completion of work as described on the attached NWP notification. Also, please note, NWP "general conditions" must be met to be in compliance.
