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 and detention facilities based on master planned release rates. 1.2 Proiect Location and Description The Willow Springs North P.U.D. is a proposed combination multi -family residential and single family residential site. This site is located in the Southeast Quarter of Section 6, Township 6 North, Range 68 West of the 6th Principal Meridian, Larimer County, Colorado. The site is bounded on the north by the Harmony Crossing P.U.D., on the east by Timberline Road, on the south by Battlecreek Drive, -and -on the west by the Union Pacific Railroad. The development is, located in the McClellands Basin and is subject to the conditions specified in the McClellands Basin Master Plan. A vicinity map illustrating the project location is provided in Figure 1. The Willow Springs North P.U.D. consists of approximately 25.3 acres. Approximately 14.1 acres is proposed for multi -family apartment units and the remaining 11.2 acres is proposed for low -density single family lots. The development will consist of 15 building pads for apartments, 8 garage pads (for the apartments), and 33 single family lots. The apartments will be two and three story buildings with no basements. Parking will be provided in the form of off street parking stalls and the 13 garage structures. All of the streets within the multi -family tract, east of Wilmington Drive, will be private and will be maintained privately. Wilmington Drive, Bent Willow Court, and Willow Leaf Court will be local public streets. 1.3 Previous Studies The "Final Drainage Report for the Village at Willow Springs" (TST Inc., September 17, 1996), the "Final Drainage Report for the Willow Springs P.U.D., Phase One" (Lidstone & Anderson Inc., May 3, 1995), and the McClellands Basin Mater Plan (Greenhorne & O'Mara, Inc, 1986) were reviewed prior to the preparation of this report. Pertinent information from those reports is referenced in this report. FIGURE 1 HARMONY ROAD Z Q W � Q 7 N \ Poriner O -� Reservoir O O v Q a = W J TRILBY ROAD VICINITY MAP Scole: 1 " = 2000' 2 I 1 2.0 ' Historic Conditions The site currently is being used for the stockpiling of excess material from the Willow Springs P.U.D. All of this excess material will be used as fill material on this project. Most of the runoff from the site currently sheet flows from west to east and discharges into an existing channel which conveys detained runoff from the Harmony Crossing P.U.D. site to the existing culverts under ' Battlecreek Drive at Timberline Road. Runoff from the western most end of the site sheet flows south and discharges directly into the McClellands Channel just west of Battlecreek Drive. ' In the "Final Drainage Report for the Willow Springs P.U.D., Phase One" (5-3-95) it was assumed that runoff from this site would need to be conveyed to the detention pond at ' Battlecreek Drive and White Willow Drive (Detention Pond 330) because the elevation of the site did not appear to accommodate onsite detention with discharge into the channel along Timberline Road. The "Final Drainage Report for the Village at Willow Springs" (9-17-96) stated the site ' was being raised with excess material from Willow Springs and could support onsite detention. That report went on to revise the design of Pond 330 and eliminated the contribution from this - site. 1 The Harmony Crossing P.U.D. lies to the north of this site. Their detention pond is located near the northeast corner of this site. Detained runoff from Harmony Crossing is conveyed across this site within an existing charnel just outside of the proposed Timberline Right -of --Way. The channel was to be constructed within an easement granted to the City by the former property owner, Elizabeth and Gerald Dusbabek. Field investigations have revealed this channel is not located entirely within the easement. The Willow Springs Phase One report identifies the 100-yr. release from the pond to be 41 cfs. This flow combined with the historic runoff from this site determined the sizing of the existing culverts under Battlecreek Drive. Recently, an error was discovered in the hydrology for the McClellands Basin Master Plan up stream of this property. The flow in the McClellands Channel west of Battlecreek Drive was over estimated which resulted in a water surface profile higher than what will actually occur. This error has been corrected and is presented in the detention analysis report for this site prepared by Lidstone & Anderson, Inc. which is included with this submittal under separate cover. 3 I 1 3.0 ' 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 1991. Where applicable, design guidelines and information were also obtained from the Denver Regional Council of Government Urban Storm Drainage Criteria Manual (USDCM). ' 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 of developed flows from this site is required by the McClellands Basin Master Plan but historic runoff computations were not necessary because the Master Plan dictates a release rate. 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 = CCfIA ' 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 =_ 0.20). Cf, _. 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 taken from the rainfall intensity duration curve in Figure 3-1 of the SDDC manual. 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=ti+A ' where t,, is the time of concentration in minutes, ti 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: ' ti = [1.87(1.1 - CCf)L0.5)/(S)0.33 4 1 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, and Cr is the storm frequency coefficient. The formula lints the product of CCr 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 calculating the flow velocity within the conveyance element assuming a flow depth equivalent to a minor storm. 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. 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 in detention ponds. Gutter flow in streets will be collected at low points via curb or area inlets or curb openings (multi -family tract only) and then conveyed to the ponds via a storm sewer system or will be directed to the ponds via drainage pans and swales. Subbasins were delineated based on proposed grading. Final grading and basin delineation are shown on the Final Grading and Drainage Plan sheets which can be found in the back of this report. The site has been graded to accommodate three detention ponds. Most of the site runoff will be directed through these ponds prior to discharge to the existing conveyance channels. Four subbasins are proposed to discharge from the site undetained. Sub -basin MCI will discharge directly to the McClellands Channel upstream of Battlecreek Drive. The 100-yr. peak discharge from this sub -basin is 2.17 cfs and will be deducted from the allowable release rate from the site. Sub -basin BC1 will discharge directly to Battlecreek Drive and will be collected by the existing storm sewer and directed to Pond 330. The 100-yr. peak discharge from this sub -basin is 0.83 cfs. The net flow to Pond 330 will actually remain unchanged though, because a portion of sub - basin 30E (see "Final Drainage Report for the Village at Willow Springs", TST, Inc., September 17, 1996) in Battlecreek Drive is being redirected and included with Sub -basin X2 and routed into Pond X on this site. The area of the redirected portion of sub -basin 30E is equivalent to the area of Sub -basin BCL Sub -basin HC1 will discharge to Wilmington Drive on the Harmony Crossing property but will add only 0.83 cfs to the street. Sub -basin MC2 will discharge directly to the existing culverts under Battlecreek Drive and the 100-yr. peak discharge of 0.18 cfs will be deducted from the allowable release rate from the site. ' The results of the Rational Method Hydrologic Analysis can be found in Table I with the methodology of calculations shown in Appendix A. Table 2 shows the results of the runoff attenuation described previously. 1 7 5 NIhINI 101-1Nle1+1001 IOI=INXOIOIn121 INIVi MIe 11Ialrl IOlpl^IpI 1 n nhnMMT--ooan —N�e �e+i—n— Mhov�Mv» oaoN �O �D �D �D h h e1 00 00 n n O �D 00 N 00 ty 00 �O 00 O oo O 00 n h O\ O N O �O O 10 V' a\ h O.

The same general criteria was used for the private streets within the multi -family tract with two notable exceptions; 1) The private streets have an inverted crown section and the allowable flow depth is determined -by the elevation of parking garage slabs which is the same for both the minor and major storms. 2) On street parking is not allowed in this tract so parking is provided in off street stalls and in the garages which eliminated the need for a capacity reduction ' factor to be applied to the allowable street flow. 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. A standard CDOT Type "C" inlet will be used at Design Point 17 in Sub -basin Z6. The inlet has more than adequate capacity for the ponding condition and was sized using Figure 5-3 of the ' SDDC manual. CDOT Type "R" curb inlets were selected at Design Points 15, 19, 22, and 26. These inlets are ' connected to storm sewer systems which convey therunoff to the detention ponds. Sidewalk culverts were utilized at Design Points 24 and 25 and convey street runoff to culverts which discharge to Pond W. The Type "R" inlets and the curb openings were sized to intercept the 100- ' yr. runoff using Figure 5-2 of the SDDC manual. Ponding depths were limited to prevent inundation of structures and, in the case of the inlets on the public streets, limited to 1.5 feet per the street encroachment criteria. In all cases the ponding depth is effective above the hydraulic ' grade line of the receiving storm sewer. The sidewalk culverts used at Design Points 24 and 25 are standard 2 foot openings. These openings will convey minor runoff but larger storms will overtop the curb but runoff will still be directed to the associated culverts that will convey it to ' Pond W. It was determined that larger openings or curb cuts would not perform any better than a standard sidewalk culvert because the downstream culverts head condition was ponding water ' over the curb anyway. This ponding was checked to ensure no buildings were inundated. The results of the Inlet Analysis and Design can be found in Table 4 with supporting calculations ' presented in Appendix C.

Lines ST-2 and ST-7 are standard closed systems with pipe materials of either ADS or RCP. Watertight Joints are specified for all sections of pipe under a surcharged flow condition. ' Line ST-5 has three reaches that have very little cover. Rather than install inlets at the associated low points it was decided to simply make each of these reaches culverts with the openings located in the low points of the subbasins. -These culverts were included in the UDSEWER model and a ' loss coefficient higher than that used for a standard inlet was used to determine the hydraulic grade lines at the openings. Lines ST-3 and ST-4 are culverts which direct runoff to Pond W and were designed using HY-8. Ponding depths at the upstream side of the culverts were limited to prevent inundation of ' structures and to remain below the ponding depth of the curb opening upstream of the culverts. Lines ST-1, ST-6, ST-8, and ST-9 are pond outlet pipes. The sizes for these pipes were ' determined by Lidstone & Anderson, Inc. as part of their analysis of the detention ponds and can be found in that supplemental report. Line ST-9 is a proposed extension of the current pond outlet for the Harmony Crossing detention pond. This pipe currently discharges into the channel ' which parallels Timberfine Road. The proposed extension of the outlet pipe will allow for a much shallower swale to be installed which can intercept runoff from the multi -family tract and convey it to Pond X. ' The results of the Storm Sewer Design can be found in Table 5 with supporting UDSEWER and HY-8 results presented in Appendix D.. 3.2.4 Riprap Design ' Riprap was placed at pipe outlets where exit velocities exceeded 5.0, fps. The two primary drainage channels on the site were graded rather flat and do not generate erosive velocities. There are three emergency spillways associated with the detention ponds, but Lidstone and ' Anderson's report indicates that only the Pond X spillway will require riprap. Our calculations indicate that Class 6 riprap will accommodate each of the pipe outlet conditions. We had originally proposed not burying the riprap so that they would better transition into the proposed cobble swales. The criteria requires that this size riprap be buried so the City agreed to ' allow us to use a Class 9 riprap that would not need to be buried. Also, the Lidstone & Anderson report indicates the outlet pipes for Pond X and Pond Z do not require riprap protection but the City insisted so we included Class 6 buried riprap at these two locations. ' Both the channels and the local swales around the multi -family units are very flat. 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 an impermeable polyethylene barrier. The multi- family tract is relatively flat and the common areas typically are over irrigated. These common areas could have been graded to sheet flow storm runoff around and away from buildings but 1 12 1 ' because of the very flat slopes the soils would remain nearly saturated most of the time due to irrigation and minor storms. 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 Riprap Design can be found in Table 6 with supporting documentation provided in Appendix E. 3.2.5 Detention Pond Analysis The analysis for the onsite detention ponds and the hydrologic and hydraulic revisions for the ' McClellands Channel can be found in the Lidstone & Anderson Inc. report titled "Regional Drainage Evaluation for the Willow Springs North P.U.D.", June 1997. That report accompanies the Final Design submittal for this project and is intended as a supplement to this drainage report. The Lidstone & Anderson report determines active capacities in the ponds, 10-yr and 100-yr water surface elevations, and an analysis of the proposed outlet pipes and orifice restrictions. Their report also includes the design of the emergency overflow facilities for each of the ponds. Pertinent information from their report is included on the Final Design Plans and was used in our evaluation of other drainage facilities on the site. ' 3.3 Erosion"Control During construction sediment will be contained on site with gravel filters over the pond outlet ' pipes and with silt fence adjacent to areas that drain offsite without passing through the ponds. Additional measures will be used upstream in the basins by installing gravel filters over all of the inlets and curb openings and straw bale check dams will be installed in the Basin X4 and X5 channels. The site will be reseeded and mulched in areas not being paved to provide soil stabilization until build out. In the multi -family tract 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 with plastic liners were necessary to prevent constantly saturated soils. 13 14 F U W ....._._ Pr+ V U U U U e 0 0 0 0 0 �O =W e0 N 00 C O F {4y N N N =a W.

One of the major advantages of wire enclosed rock is that it provides an alternative in situations where available rock sizes are too small for ordinary riprap. Another advantage is the versatility that results from the regular geometric shapes of wire enclosed rock. The rectangular blocks and mats can be fashioned into almost any shape that can be 11-15-82 ' Table 8-1 lists several gradations of riprap. The minimum average size designation for loose riprap shall be 12 inches. Smaller sizes of riprap shall be either buried on slopes which can be easily maintained (4 to 1 minimum side slopes) or grouted if slopes are steeper. Grouted riprap should meet all the requirements for regular riprap except that the smallest rock fraction (smaller than the 10 per- cent size) should be eliminated from the gradation. A reduction of riprap size by one size designation (from 18 inches to 12 inches or from 24 inches to 18 inches) is permitted for grouted riprap.

The rock sizing requirements in Table 8-2 are based on the rock having a specific gravity of 2.5 or ' more. Also, the rock size does not need to be increased for steeper channel side slopes, provided the side slopes are no steeper than 2h:1v. Rock lined side slopes steeper than 2h:1v are not recommended.
