Results from this analysis are intended to demonstrate that the proposed drainage system complies with the City ofCollege Station Drainage Policy and Design Standards (DPDS) by controlling runoff from this site. LOCATION: The site is located in southern College Station, on the south side of Graham Road near its intersection with Wellborn Road. The north property line adjoins the various commercial sites that front onto Graham Road. Bordering the site on the east is the Westfield Subdivision, including the future extension of Victoria Avenue. The south side is bordered by the Bald Prairie Subdivision and undeveloped property owned by W. Barton Munro. The west is bordered by TXDOT right -of -way for Wellborn Road and the future extension of SH 40. DESCRIPTION: The site encompasses an area of 86.028 acres. It is generally open pasture with the exception of some heavily wooded areas along the drainage channel in the middle of the property. The site drains in an easterly direction with slopes ranging between 0.5% and 2 %. The natural drainage system for the site is an unnamed tributary of the South Fork of Lick Creek, which is a tributary of Carters Creek. This site is not located in a 100 -Year Flood Hazard Area according to the FEMA Flood Insurance Rate Maps for Brazos County, Texas (Map Nos. 48041C182 C, 48041C200 C, and 48041C205 C effective July 2, 1992) Pertinent sections of these maps are shown in Exhibit A. DRAINAGE DESIGN CRITERIA: The proposed drainage system is designed in accordance with the City of College Station's DPDS. The design storm for the underground system is a 10 -year event and flow calculations are based on the Rational Method. Pipe sizes were determined using Manning's Equation with an "n" of 0.014. DRAINAGE ANALYSIS 1 EDELWEISS GARTENS SUBDIVISION The detention pond was analyzed using two computational options.. The two options were: • HEC -1 SCS Method (Type II, 24 -hour storm, Curve number losses, SCS Unit hydrograph for distribution, and SCS lag) • Triangular Hydrograph Method (Rational Formula / Storage Routing Method) STORM DRAIN FACILITY DESIGN: The proposed design allows stormwater to be captured in the curbs, conveyed to the inlets and into the underground storm drainage system. The underground system discharges directly into the detention facility. Exhibit B is the drainage area map that shows the subbasins associated with Phase 1 of Edelweiss Gartens, as well as those associated with the Graham Road outfall. (This outfall is intended to be a joint project between the City of College Station and the developer.) Runoff calculations for each drainage area are shown in Exhibit C -1. Exhibits C -2 and C -3 show the inlet computations and pipe size computations derived from these runoff calculations. DETENTION FACILITY DESIGN AND ANALYSIS: The proposed detention facility is located upstream of Victoria Avenue and is designed to detain runofffrom the 5, 10, 25, 50 and 100 year rainfall events. The pond outlet is a three -stage structure with the first stage consisting of a 30" RCP culvert. The second and third stages consist of risers set at elevations 295.5' and 299.0' respectively. These connect to a triple 6'x 5' box culvert that continues under Victoria Avenue. The detention facility is made up of the existing drainage channel and an earthen berm constructed around the perimeter of the pond to provide additional storage. The top of berm elevation is 302.0' and the emergency spillway elevation is 301.30'. The emergency spillway length is approximately 200 feet. Exhibit D -1 shows the drainage area map for the South Fork of Lick Creek which includes the proposed site. Exhibit D -2 gives the parameters in each drainage area for the Pre - Development conditions (Plan 1) and the Post - Development conditions (Plan 2). For each of these two plans, the following rainfall events (known as rations in HEC -1) were analyzed: Ratio 1: 500 Year Storm Ratio 2: 100 Year Storm Ratio 3: 50 Year Storm DRAINAGE ANALYSIS 2 EDELWEISS GARTENS SUBDIVISION Ratio 4: 25 Year Storm Ratio 5: 10 Year Storm Ratio 6: 5 Year Storm Ratio 7: 2 Year Storm Exhibit D -3 shows the stage /storage /discharge routing through the detention facility. Exhibit D -4 is a printout of the HEC -1 analysis. A printout from the second analysis method using the Triangular Hydrograph method is shown in Exhibit D -5. It is provided as a comparison with the HEC -1 method and to demonstrate how the detention pond performs under the two hour storm used in the Rational Formula analysis. The 5, 10, 25, 50, and 100 years storms were studied with this method. SUMMARY: Table 1 is a summary ofthe Pre and Post - Development flowrates at Victoria Avenue taken from the HEC -1 analysis in Exhibit D -4. Table 2 shows the Pre and Post - Development flow rates from the Triangular Hydrograph routing in Exhibit D -5. TABLE 1 Study Point - Victoria Avenue - HEC -1 Design Event Pre - Development Post - Development Pond Water Surface Q 317 cfs 319 cfs 299.21 Q10 413 cfs 407 cfs 299.92 Q25= 528 cfs 490 cfs 300.61 Q50 611 cfs '573 cfs 301.08 Q100 711 cfs 708 cfs 301.37 Top of Berm = 302.00 Spillway Elev. = 301.30 DRAINAGE ANALYSIS 3 EDELWEISS GARTENS SUBDIVISION TABLE 2 Study Point - Victoria Avenue - Triangular Hydrograph Design Event Pre- Development Post - Development Pond Water Surface Q 321 cfs 293 cfs 299.00 Q 367 cfs 339 cfs 299.40 Q25= 422 cfs 391 cfs 299.80 Q50= 481 cfs 439 cfs 300.20 Q 100 546 cfs 489 cfs 300.60 Top of Berm = 302.00 Spillway Elev. = 301.30 As indicated above in Table 1, the 5 year rainfall event produces a post - development runoffrate that is two cubic feet per second higher than the pre - development runoffrate. Small increases like this often occur when large drainage basins are routed through detention ponds. In those scenarios, the first stage outlet structures must be sized slightly larger to accommodate bigger rainfall events, thereby causing reduced attenuation of the smaller rainfall events. The small increase shown in Table 1 is insignificant and will have no perceptible impact on the downstream channel capacity. The post - development runoff rates for the 10, 25, 50 and 100 year storm are all reduced from their corresponding pre - development rates. All of the water in the detention pond is restricted to the primary drainage channel, public rights -of -way or public drainage easements. Tables 1 and 2 show that the two computational methods produce slightly different results in terms of the flow rates and the pond water surface elevations. This is expected since the HEC -1 study uses a 24 hour storm and the Rational Method uses a storm duration of less than 2 hours. The outlet structure, emergency spillway, and top of berm were designed using the higher flow rates from the HEC -1 analysis. The proposed outfall from the detention pond consists of three 6'x 5' concrete box culverts that are extensions of the Victoria Avenue crossing structure. The Victoria Avenue crossing structure is being designed as part of an adjacent Westfield development. Details regarding flowrates and the detention pond have been shared with that developer's engineer to insure proper sizing of the structure.
