PRIMARY DRAINAGE BASIN DESCRIPTION: The proposed site is located in the WOODCREEK SUBDIVISION in the southern portion of College Station along the western line of Stonebridge Drive and Stonebrook Drive, approximately 200 feet from the Rock Prairie Road intersection. The site is contiguous to Woodcreek Section One to the north and Woodcreek Section Six to the West. To the south of the site is an undeveloped parcel and agricultural land. The site is wooded with 2 % to 3 % slopes. Some grading has been conducted south of the site with the construction of Stonebrook Drive. Offsite storm water flows across this site from the northwest, but the flow is not concentrated (See Exhibit "D", Portions of Drainage Areas 1, 2A, 7, & 9). The site drains primarily into Lick Creek, a major tributary of Carter's Creek. The future Rock Prairie Road realignment intended to eliminate the offset at State Highway Six will affect · the drainage of this subdivision. The new alignment will tend to allow the storm water flows from this development to go toward the Foxfire Tributary of Carter's Creek through the existing Woodcreek and Foxfire Subdivisions. Because of the location of the subdivision on a drainage divide, this may seem natural, but is in fact a diversion of a fairly significant amount of drainage into an existing developed drainage way. This diversion should be avoided. Another factor of notice is the lack of a storm drain system in the Stonebrook Drive Right of Way. During the design of Stonebrook Drive, the designer argued that because of a lack of outfall, he could not provide a storm drain. There is no drainage report on file at the City of College Station for this section of the Woodcreek project, but the communications file for the project shows that the engineer computed quantities of gutter flow which are well in excess of the curb capacity. This fact controlled the design of the project. The proposed Woodcreek Section Seven is not located in a 100-year flood hazard area according to the F.E.M.A. Flood Insurance Rate Maps for Brazos County, Texas and Incorporated Areas, Map Number 48040C0205 C, effective July 2, 1995 (See Exhibit "A"). GENERAL CONCEPT: The flows will be divided as shown on the attached Drainage Area Map (See Exhibit "D"). The areas flowing to the existing ditch line along Rock Prairie Road (Drainage Areas 1 - 8) continue to flow to this point. The drainage area flowing in the gutter lines of Stonebrook Drive are denoted as Drainage Areas 6 & 8 (See Exhibit "B"). Note that the total drainage area to flow down Stonebrook is lessened by the grading of Wilshire Court. Drainage Areas 1, 2A, 2B, and 3 are intercepted by the storm drainage system built with this section and conveyed to -2 - the detention area. Drainage Areas 5 and 7 flow to the detention pond without interception in the storm drain system. Drainage Areas 4 , 6 , 8, and 9 will bypass the detention area. The detention area will outfall via a proposed 18" pipe in a Public Drainage Easement to the north ditch line of Rock Prairie Road. The future improvement of Rock Prairie Road must incorporate a storm drain system to convey this flow to Lick Creek. The area defined as Drainage Area 9 will not have an increase of impervious cover and will not be altered by this project . Per the City of College Station Storm water Management Ordinance the 10 -year storm will be confined to the curb lines (See Exhib it "E" for Street Capacity Data) of proposed the Wilshire Court, and the 100-year storm will be controlled within the rights-of-way and easements (See Exhibit "F" for the Overflow Section Design) and will flow to the proposed detention pond and Rock Prairie Road ditch line . The proposed pond is sized to detain the five , ten, twenty-five, and one hundred year storms, such that post development flow is less than or equal to the predevelopment flow . See Table "A" for peak flow data at the Study Point , located at the Rock Prairie Road ditch line. Note that the peak discharges for each storm event have been significantly reduced at the study point. This is because the Drainage Areas 4 and 6 are allowed to bypass the pond and have a shorter time of concentration and a higher "C" value than their predeveloped condition . Drainage Areas 1, 2A , 2B , 3 , 5 , and 7 are detained , thereby increasing their time of concentration. This fact is demonstrated in Exhibit "G".

The pond will have excellent access from Wilshire Court and is designed with low maintenance outlet structures (standard sloped headwall, 18" R.C.P., 10' earthen weir, and a 5' wide berm with 4: 1 side slopes). The pond as designed will have .5' of free board for the 100- year storm, and no flows in the overflow weir during the 100-year storm. The attached HEC-1 computer printout (see Exhibit "C") shows how the pond will function in the event of the design storms. The ability of HEC-1 to handle multiple triangular hydrographs is limited.

PRIMARY DRAINAGE BASIN DESCRIPTION: . The proposed site is located in the WOODCREEK SUBDMSION in the southern portion of College Station along the western line of Stonebridge Drive and Stonebrook Drive , approximately 200 feet from the Rock Prairie Road intersection. The site is contiguous to Woodcreek Section One to the north and Woodcreek Section Six to the West. To the south of the site is an undeveloped parcel and agricultural land. , The site is wooded with 2 % to 3 % slopes. Some grading has been conducted south of the site with the construction of Stonebrook Drive. Offsite storm water flows across this site from the northwest, but the flow is not concentrated (See Exhibit "D", Portions of Drainage AreasJ, 2A, 7, & 9). The site drains primarily into Lick Creek, a major tributary of Carter's ; Creek. The future Rock Prairie Road realignment intended to eliminate the offset at State Highway Six will affect the drainage of this subdivision. The new alignment will tend to allow the storm water flows from this development to go toward the Foxfire Tributary of Carter's Creek through the existing Woodcreek and Foxfire Subdivisions. Because of the location of the subdivision on a drainage divide, this may seem natural, but is in fact a diversion of a fairly significant amount of drainage into an existing developed drainage way. This diversion should be avoided. Another factor of notice is the lack of a storm drain system in the Stonebrook Drive Right of Way. During the design of Stonebrook Drive, the designer argued that because of a lack of outfall, he could not provide a storm drain. There is no drainage report on file at the City of College Station for this section of the Woodcreek project, but the communications file for the project shows that the engineer computed quantities of gutter flow which are well in excess of the curb capacity. This fact controlled the design of the project. The proposed Woodcreek Section Seven is not located in a 100-year flood hazard area according to the F.E.M.A. Flood Insurance Rate Maps for Brazos County, Texas and Incorporated Areas, Map Number 48040C0205 C, effective July 2, 1995 (See Exhibit "A"). GENERAL CONCEPT: The flows will be divided as shown on the attached Drainage Area Map (See Exhibit "D"). The areas flowing to the existing ditch line along Rock Prairie Road (Drainage Areas 1 - 8) continue to flow to this point. The drainage area flowing in the gutter lines· of Stonebrook Drive are denoted as Drainage Areas 6 & 8 (See Exhibit "B"). Note that the total drainage area to flow down Stonebrook is lessened by the grading of Wilshire Court. Drainage Areas 1, 2A, 2B, and 3 are intercepted by the storm drainage system built with this section and conveyed to -2- the detention area. Drainage Areas 5 and 7 flow to the detention pond without interception in the storm drain system. Drainage Areas 4, 6, 8, and 9 will bypass the detention area. The detention area will outfall via a proposed 18" pipe in a Public Drainage Easement to the north ditch line of Rock Prairie Road. The future improvement of Rock Prairie Road must incorporate a storm drain system to convey this flow to Lick Creek. The area defined as Drainage Area 9 will not have an increase of impervious cover and will not be altered by this project. Per the City of College Station Storm water Management Ordinance the 10-year storm will be confined to the curb lines (See Exhibit "E" for Street Capacity Data) of proposed the Wilshire Court, and the 100-year storm will be controlled within the rights-of-way and easements (See Exhibit "F" for the Overflow Section Design) and will flow to the proposed detention pond and Rock Prairie Road ditch line. The proposed pond is sized to detain the five, ten , twenty -five, and one hundred year storms, such that post development flow is less than or equal to the predevelopment flow. See Table "A" for peak flow data at the Study Point, located at the Rock Prairie Road ditch line. Note that the peak discharges for each storm event have been significantly reduced at the study point. This is because the Drainage Areas 4 and 6 are allowed to bypass the pond and have a shorter time of concentration and a higher "C" value than their predeveloped condition. Drainage Areas 1, 2A, 2B , 3, 5, and 7 are detained, thereby increasing their time of concentration. This fact is demonstrated in Exhibit "G". Table "A" is generated for these areas by summing the flows from both controlled and uncontrolled areas. The flows shown as "Existing Flow" in Table "A" are computed in Exhibits "B" and "G". -3 - The pond will have excellent access from Wilshire Court and is designed with low maintenance outlet structures (standard sloped headwall, 18" R. C. P., 10' earthen weir, and a 5 ' wide berm with 4:1 side slopes).

GENERAL CONCEPT: The flows will be divided as shown on the attached Drainage Area Map (See Exhibit "D "). The areas flowing to the existing ditch line along Rock Prairie Road (Drainage Areas 1 -8) continue to flow to this point. The drainage area flowing in the gutter -2- lines of Stonebrook Drive are called Drainage Areas 6 & 8 (See Exhibit "B") • Note that the total drainage area to flow down Stonebrook is lessened by the grading of Wilshire Court. Drainage Areas 1, 2A, 2B, 3, & 5 are intercepted by the storm drainage system built with this section and conveyed to the detention area. Drainage Areas 4, 6, 7, 8, & 9 will bypass the _detention area. The detention area will outfall into a proposed improved ditch line offsite of the subdivision in a Drainage Easement. The proposed / improved ditch line will convey the flow to the ditch linep of Rock Prairie Road. The future improvement of Rock Prairie Road must incorporate a storm drain system to convey this flow to Lick Creek. Drainage area 9 is the only area affected by this subdivision which does not flow to Lick Creek. The area defined by drainage area 9 will not have any proposed impervious area and will not be altered by this project. Per the City of College Station Stormwater Management Ordinance the 10-year storm will be confined to the curb lines (See Exhibit "E") of proposed the Wilshire Court, and the 100-year storm will be controlled within · the rights-of-way and easements (See Exhibit "F") to the proposed detention pond. The proposed pond is sized to detain (post development flow <= predevelopment flow) the five, ten, twenty five, and one hundred year storms. See Table "A" for peak flow data at the study Point, the ditch line to Rock Prairie Road at the subdivision Boundary. Note that the peak discharges for each storm event has been significantly reduced at -3- the study point. This is because the drainage areas allowed to bypass the pond (Areas 4 , 6 , & 7) have a shorter time of concentration and a higher "C" value than their predeveloped condition. Drainage Areas 1, 2A, 2B, 3 and 5 are detained, thereby increasing their time of concentration. Table "A" accounts for these areas by summing the flows from both controlled and uncontrolled areas. The pond will have excellent access from Wilshire Court and is designed with low maintenance outlet structures (standard sloped headwall, 18" RCP, 10' earthen weir, and a 5' wide berm with 4:1 side slopes). The pond as designed will have .7' of free board for the 100-year storm, and no flows in the overflow weir during the 100-year storm. The attached HEC-1 computer printout (see Exhibit "C") shows how the pond will function in the event of the design storms. TABLE A STORM Routed Flow Bypass Flow Total Ex. Flow (Yr.)
