First Filing Information Sheets Drainage & Erosion Control Plan le Introduction 1.1 Scope and Purpose ' This report presents the results of a final drainage evaluation for the Registry Ridge P.U.D., Second Filing. A hydrologic analysis of the proposed development plan was completed to determine the location and magnitude of the storm runoff. The hydrologic data was then used to ' evaluate conveyance facilities. 1.2 Proiect Location and Description The Registry Ridge P.U.D., Second Filing is a proposed multi -family residential and commercial site. This site is located in Section 15, Township 6 North, Range 68 West of the 6`s Principal ' Meridian, Larimer County, Colorado. The site is bounded on the north, west and south by Registry Ridge P.U.D. First Filing (Truxtun Dr., Nimitz Dr., and Bon Homme Richard Dr.), and on the east by Shields St. A vicinity map illustrating the project location is provided in Figure 1. ' The Registry Ridge P.U.D., Second. Filing consists of approximately 14.66 acres. The development will consist of approximately 21 townhouse buildings, a convenience store, a retail ' store, and a daycare. The townhouses will be two story buildings with basements and attached garages. All streets, with the exception of Enterprise Dr. are private and will be privately maintained. ' 1.3 Previous Studies ' The "Final Drainage Report for Registry Ridge P.U.D. First Filing" (Northern Engineering Services, Inc., July 24, 1998) was reviewed prior to the preparation of this report. Pertinent information from this report was utilized and has been included in Appendix F. 1 TST, Inc. 1 September 5, 2000 ' 0890-001 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 FIGURE 1 HARMONY ROAD z W 2 F..

First Filing (First Filing) at the southeast corner of the site. Some runoff discharges directly onto the surrounding streets and is collected at existing inlets on Storm Lines 10 & 32 of First Filing. In addition, runoff from First Filing Storm Line 26 is discharged into a swale that crosses the center of the site and discharges in Storm Line 32. TST, Inc. 0890-001 3 September 5, 2000 e 1 10 Developed Conditions Plan 3.1 Design Criteria ' The drainage system presented in this report has been developed in accordance with the criteria established by the City of Fort Collins Storm Drainage Design Criteria and Construction ' Standards Manual (SDDC) dated May 1984 and revised in January 1997. Where applicable, design guidelines and information were also obtained from the Denver Regional Council of Government Urban Storm Drainage Criteria Manual (USDCM). The drainage system also meets ' conditions as presented in the Final Drainage Report for Registry Ridge P.U.D. First Filing (First Filing). Developed condition hydrology was evaluated based on the 2-year and 100-year storm frequencies as dictated by Table 3-1 of the SDDC manual. Detention for the site has been accounted for in detention ponds in First Filing, therefore, no onsite detention is proposed. ' Because of the limited size of the subbasins on the site, the Rational Method was selected to calculate runoff. The Rational Method utilizes the SDDC manual equation: Q = CC fIA where Q is the flow in cfs, C is the runoff coefficient, Cf is the storm frequency coefficient, I is the rainfall intensity in inches per hour, and A is the total area of the basin in acres. The runoff ' coefficient, C, was calculated from Table 3-3 of the SDDC manual based on the proposed developed condition land use. A composite runoff coefficient was calculated for each sub -basin based on the percentage of impervious surface (C = 0.95) and pervious surface (C = 0.25). Cr ' was taken from Table 3-4 of the SDDC manual and was determined to be 1.0 for the 2-year storm and 1.25 for the 100-year storm. The appropriate rainfall intensity was obtained from the Intensity Formula for Registry Ridge P.U.D. determined by Northern Engineering Services and presented in the First Filing report. To obtain the rainfall intensity, the time of concentration had to be determined. The following equation was utilized to determine the time of concentration: ' tc = t; + tt where t, is the time of concentration in minutes, t; is the initial or overland flow time in minutes, ' and t, is the travel time in the gutter in minutes. The initial or overland flow time was calculated with the SDDC manual equation: tt, = [1.87(l.1 - CCf)I,0.5)/(S)0.33 TST, Inc. 4 September 5, 2000 ' 0890-001 I I where L is the length of overland flow in feet (limited to a maximum of 500 feet), S is the average basin slope in percent, C is the composite runoff coefficient for the area of overland flow (different from the composite runoff coefficient for the entire basin and used to match the methodology of the First Filing report), and CF is the storm frequency coefficient. The formula limits the product of CC, to 1.0 and when the product exceeds this value 1.0 is used in its place. Gutter (or channel) travel times were determined by utilizing Figure 3-3 for the flow velocity ' within the conveyance element. The travel time was then determined by dividing the gutter flow length by the velocity. This procedure for computing time of concentration allows for overland flow as well as travel time for runoff collected in streets, gutters, channels, or ditches. After the ' peak runoff was calculated, attenuated runoff was calculated. This was done by combining all contributing areas upstream of a given design point. The time of concentration for the design point was taken as the greatest time of all the contributing subbasins and adding in pipe travel ' time if necessary. ' 3.2 Drainage Plan Development The proposed drainage plan consists of a combination of overland flow and gutter flow. The runoff will sheet flow across landscaped yards, common areas and parking lots, then concentrate at proposed streets or swales. Gutter flow in streets will be collected at low points via curb inlets or curb openings and then conveyed via a storm sewer system to the water quality ponds of First ' Filing. Subbasins were delineated based on the proposed grading. Final grading and basin delineation is shown on the Drainage & Erosion Control Plan sheets, which can be found in the back of this report. ' All subbasins are proposed to discharge from the site undetained. The runoff from the site was compared to the runoff assumed in the Final Drainage Report for Registry Ridge P.U.D. First Filing, and was found to be in compliance with that report. Basin delineation used in this report matches that of the First Filing report to aid in comparisons. Basin 403 contains the majority of the site and drains to the south. This basin also includes the offsite area to the west of the site that discharges onto the site via First Filing Storm Line 26. Storm drainage from this basin will be collected via storm sewer and routed to First Filing Storm ' Line 32. Basin 402 contains the northeast portion of the site and discharges to the north. Storm drainage ' from this basin will be collected via storm sewer and routed to First Filing Storm Line 10. The results of the Rational Method Hydrologic Analysis can be found in Table 1 with the ' methodology of calculations shown in Appendix A. Table 2 shows the results of the runoff attenuation described previously.

The same general criteria was used for the private streets within the multi -family tract with a notable exception; the private streets have a valley pan section and the allowable flow depth is determined by the elevation of attached garages which is the same for both the minor and major storms. All of the public and private streets meet these requirements and will function below the allowable capacities. The results of the Street Capacity Analysis can be found in Table 3 with supporting calculations presented in Appendix B. ' 3.2.2 Inlet Design Area inlets, curb inlets, and curb openings were used to collect 100-yr. runoff from low points. Design Points 6 & 8 utilize curb openings to convey the storm runoff to adjacent swales. Ponding depths were limited to prevent inundation of structures. The openings will convey the 2-yr runoff without overtopping the curb, with the 100-yr overtopping the curb but runoff still being directed to the appropriate swales without inundating any buildings. An area inlet was designed for Design Point 7. This inlet was sized according to Figure 5-3"of the SDDC manual and is sized to convey the 100-yr runoff. ' CDOT Type "R" curb inlets were selected at Design Points 2, 4, 5, 12, & .13. These inlets are connected to storm sewer systems that convey the runoff to First Filing Storm Lines 10 & 32. ' The results of the Inlet Analysis and Design can be found in Table 4 with supporting calculations presented in Appendix C. ' 3.2.3 Storm Sewer Design Storm Sewer Lines ST-1, ST-IA, and ST-1B were designed with UDSEWER to convey the 100- yr. runoff in Basin 403. ST-1 connects to First Filing Storm Line 32 at the downstream end, and Storm Line 26 at the upstrearn. The water surface at the downstream end of STA was determined from the First Filing Report. Line ST-IA contains an online stormcepter capable of intercepting a minimum of 150 gallons of spilt gasoline. The entire system, existing and proposed, was modeled to assure no negative impacts on the existing system. Information was obtained from the First Filing report for this purpose. The pipes were sized such that the hydraulic grade remains below the flow line of the proposed inlets. Line ST-2 was also analyzed with UDSEWER. It discharges runoff from Basin 402 and connects to First Filing Storm Line 10 at the existing inlet. The 100-yr water surface was determined from the First Filing report. ' The results of the Storm Sewer Design can be found in Table 5 with supporting UDSEWER and HY-8 results presented in Appendix D. TST, Inc. 9 November 6, 2000 0890-001 M 10 1 §i 11 TABLE 5.

CONSULTING ENGINEERS 12 11/6/00 890001_hyd.xis 3.2.4 Swale Design The drainage swale from Design Point 6 conveys water from Subbasin 1D to the street in Subbasin 1C. The drainage swale in Subbasin lE conveys water from the Subbasin IF curb opening to the area inlet at Design Point 7. These swales have been designed to function as a mowed grass swale with a concrete trickle pan. In addition, several swales with cobble trickle pans direct flow around buildings and discharge into the street via curb openings. The multi -family tract is relatively flat and the common areas typically are over irrigated. To prevent saturation of soils in the swales and at other locations cobble trickle pans are proposed. These pans will consist of 2" to 4" cobble overlaying a concrete valley pan. We have used this method of installing nuisance channels successfully in the past and believe they function adequately in this case as well. These swales and the associated pipes under the sidewalks were not evaluated as part of this report because they are intended to only provide small storm and nuisance protection. Runoff from larger storms will obviously utilize these conveyances as well but will act more as sheet flow once these facilities are inundated. The results of the swale analysis can be found with supporting calculations in Appendix E. ' 3.3 Erosion Control During construction. sediment will be contained on site with silt fence around the site. Additional measures will be used in the basins by installing gravel filters over all of the inlets and curb openings. The site will be reseeded and mulched in areas not being paved to provide soil stabilization until build out. It is anticipated that once the buildings are completed an irrigation system will be installed and the common areas sodded. If there is to be a delay of more than 30 days in the construction of the buildings, the disturbed areas will be reseeded and ' mulched. Erosion of soils in the onsite channels and swales are not a concern. Velocities are very low due to the flat slopes, so low in fact that cobble trickle pans were necessary to prevent constantly saturated soils. As this project was completed under the LDGS system of the City of Fort Collins, water quality measures are not required. In addition, this project develops an area that was included in the "Final Drainage Report for Registry Ridge P.U.D. First Filing" by Northern Engineering (also under LDGS) and was accounted for in the main detention ponds. Because of this, no onsite detention was required. The water quality benefits that are provided include those discussed above during construction, and grass swales in the detention ponds between the storm sewer outlets and the concrete pans in the bottom. The grass swales will allow sediments to be trapped prior to release from the pond during minor storms. TST, Inc. 13.
