INTRODUCTION This report summarizes the drainage investigations conducted for the parking lot expansion at Dellenbach Chevrolet, located in the southwest corner of Section 26, Township 7 North, Range 69 West of the 6th P.M. The address of the site is 3111 South College Avenue between Foothills Parkway and Swallow Road. 2. EXISTING DRAINAGE CONDITIONS The parking lot expansion is located in the southwest corner of the Dellenbach Chevrolet site (Figure 1). This area is lower than surrounding parking lots and streets and currently does not drain. This area is at the upstream point of the Dellenbach site, and does not collect stormwater runoff from any of the developed portion of the Dellenbach site. It is RCE's understanding from discussions with the City of Fort Collins Stormwater Utility personnel that this is an old detention pond and is no longer being used. It is the intent of the owners of the property to expand the existing parking lot into this area. Since this site is no longer being used for stormwater detention, current owners would like to fill in the area and utilize it for additional parking on the site. This area drains to the east and ponds at the center of the triangular depression (point 1, see enclosed grading plan). Peak runoff from the area was computed at concentration point 1 using the rational method. Using C = 0.20, slope = 1.8 percent and area = 0.38 acres, the runoff for a 10-year storm event is 0.3 cfs and 0.6 for a 100-year storm event. For existing conditions, all runoff for this area would be contained within the basin boundaries. Peak runoff was computed for concentration point 2 also using the rational method. Using C = 0.95, slope = 0.55 percent and area = 12.89 acres, the runoff for a 10-year storm event is 55.4 cfs and 109.6 for a 100-year storm event. The water drains from the Dellenbach she and from the properties along the frontage road south of the she. This water collects at inlets at the southeast comer of the Dellenbach parking lot and northeast corner of the First Bank lot. 3. PROPOSED DRAINAGE CONDITIONS The proposed parking lot expansion will be filled to approximately the same grade as the existing adjacent parking lot. Additionally, it will be graded to drain to the east to an area inlet. Any flow the area inlet could not drain would spill to the northeast and would be conveyed to the east to the 1 Resource Consultants & Engineers, Inc. 0 0 N 11 O L O o C U n O I o N � N W C C d W W v Oo > U d O F � w U-O a.o a 0 �NEN a d 0 0 O LO In c ° E o O a O O o EC0c 3 N I m O � as C c= R _N CO O 0 0 0 W ( O • v. �1 C aEi 2 Resource Consultants & Engineers, Inc. I ' storm drain inlets at the College Avenue frontage road. Peak runoff was computed at concentration point 1 using the rational method. Using C = 0.95, slope = 0.55 percent and area = 0.38 acres, the runoff for a 10-year storm event is 2.1 cfs and 3.5 cfs for a 100-year storm event. For the 10-year storm event, the runoff increased 1.8 cfs and 2.9 cfs for 100-year storm event. ' It is proposed to construct an area inlet at the south boundary of parking lot expansion. The ' inlet will drain into an existing 8-inch pipe which drains into a 12-inch pipe in the Steeles Market parking lot. The 12-inch pipe drains into a 48-inch pipe. Hydraulic analysis of the 12-inch storm drain in Steeles Market parking lot indicates that storm does not have sufficient capacity to drain the Dellenbach ' expansion parking lot. It, therefore, will be used as a low -flow drain. The expansion parking lot will detain 747 cubic feet of water before overflowing to the northeast. Overflow waters will flow to ' concentration point 2. ' Peak runoff was computed for concentration point 2, including the parking lot expansion area. Using C = 0.95, slope - 0.55 percent and area = 13.27 acres, the runoff for a 10-year storm event is ' 57.0 cfs and 112.8 for a 100-year storm event. For the 100-year storm event, the runoff increased 1.6 cfs (3%) and 3.2 (3%) for the 100-year storm event. ' The runoff from the Dellenbach Chevrolet site and adjacent properties drain to the low point in the frontage road at the storm drains located along the 48-inch storm drain (Figure 2), except the Steeles Market which drains to sump inlets located on their property. To determine if the increased runoff from the parking lot expansion significantly increase the ponded water level at the storm drain ' inlets, the cumulative runoff method was used. In this analysis, it was assumed the 48-inch storm drain would not restrict flow of water into the inlets. In addition, 747 cubic feet was assumed to be stored in ' the low area in the expansion parking lot. For existing conditions using a composite C = 0.95, areas = 12.89 acres, and an outflow rate ' of 25.1 cfs, the maximum volume of water stored in the ponded area is 18,775 cubic feet of water for the 10-year storm event. For the 100-year storm event using an outflow rate of 30.0 cfs, the maximum ' volume of water stored in the ponded area is 44,934 cubic feet. This corresponds to elevations 5023.18 and 5023.73, respectively. ' For proposed conditions using composite C = 0.95, areas = 13.27 acres, and an outflow rate ' of 25.2 cfs, the maximum volume of water stored in the ponded area is 19,352 cubic feet of water for the 10-year storm event. For the 100-year storm event using an outflow rate of 30.2 cfs, the maximum volume of water stored in the ponded area is 46,377 cubic feet. This corresponds to elevations 5023.19 ' and 5023.76, respectively. 3 Resource Consultants & Engineers, Inc. 1 N 1"- 100 b 502E tip /• DELLENBACH ho I CHEVROLET to a �502e IZ i—100Yr. H.W.L.

Ponding area at southeast corner of Dellenbach site. 4 Resource Consultants & Engineers, Inc. ' The increase in ponded elevation from existing to proposed conditions is +0.01 and +0.03 feet for the 10- and 100-year storm events, respectively. The increase in ponding during the 10-year event ' is negligible. While the increase in ponding during the 100-year event is only 0.03 feet because of the topography, most of the additional area inundated (1,500 sq. ft.) is in the Dellenbach parking lot. The ' total depth of ponding during the 100-year event offsite is 1.76 feet compared with existing 1.73 feet. This increased ponding should not create additional damage. Since there is no reasonable alternative ' to increase detention on the proposed area to be paved and effects downstream are primarily on the Dellenbach property, approval of the drainage plan is requested. ' Appendix A contains detailed hand calculations of the investigations conducted. Since the expansion parking lot is very small (0.38 acre) and construction of the expansion parking lot will take less than 30 days, a variance is requested to not prepare an erosion control study. The area inlet will be protected with a straw bale dike during construction. ' 4. SUMMARY The owners.of Dellenbach Chevrolet desire to increase the parking of the property by expanding tinto the old detention pond area. Presently, the old detention pond serves no significant useful storm drainage purpose and the City of Fort Collins Stormwater Utility will allow @ to be abandoned. By ' creating a paved parking lot at the old detention pond site, runoff will increase by 1.6 and 3.2 cfs for the 10- and 100-year storm events, respectively. The expansion parking lot will be graded to drain to an ' area inlet to be constructed at the eastern end of the parking lot. The area inlet will drain into an existing storm drain system, which is undersized and has limited capacity. The area inlet will be used ' as a low -flow outlet only. Water will pond at the inlet and overflow to the northeast into the existing Dellenbach parking lot. Runoff will collect at the low area in the frontage road to College Avenue at the storm drain inlets along the 48-inch storm drain. Runoff water ponded at the inlets will increase only ' slightly for the 10- and 100-year storm events, due to the expansion parking lot, but should not adversely affect adjacent properties. Since the expansion parking lot is very small (0.38 acre) and construction ' of the expansion parking lot will take less than 30 days, a variance is requested to not prepare an erosion control study. The area inlet will be protected with a straw bale dike during construction. 5 Resource Consultants & Engineers, Inc.
