INTRODUCTION 1.1 Objective This report summarizes the results of a comprehensive analysis of both pre and post - development hydrologic and hydraulic conditions, for the Kechter Road Improvements. 1.2 Mapping and Surveving ' King Surveyrors of Windsor, Colorado provided aerial topography of the site with a contour interval of one (1) foot. Supplemental topography north of Kechter Road, east of McClelland's channel was obtained from digitized City of Fort Collins Orthophoto Maps flown ' April 12, 1984. 1.3 Site Reconnaissance The project engineer conducted a site visit on May 6, 1998, then again in June 2001. Based on the topographic mapping, existing drainage basins and land use were confirmed as well as existing structures. The location and dimensions of existing culverts were verified as well as their condition and flow direction. II. SITE LOCATION AND DESCRIPTION 2.1 Site Location ' The Kechter Road Improvements associated with Fossil Lake Second Filing are located in the West Half of Section 9, Township 6 North, Range 68 West of the Third Principal Meridian in Larimer County, Colorado (See Vicinity Map). The stretch of roadway is bounded by the ' intersection of Ziegler Road and Kechter Road on the west and the Fossil Lake Second Filing boundary on the east. The north and south boundaries consist of agricultural land. 2.2 Site Description The Kechter Road Improvements constitute approximately 6.63 acres of improved roadway. Existing agricultural land to the north drains away from the road, northeast, to McClelland Channel. Approximately 20.74 acres of agricultural land on the south side of the road drains northeast into Kechter Road before traveling east into McClellands Channel. Some agricultural land to the south drains directly into McClellands Channel. Approximately 235 acres south of Kechter Road and west of Ziegler Road drains northeast through two existing 18" culverts in the Ziegler\Kechter intersection to McClellands Channel. There are existing residences offsite on the south side of the road. ' Drainage Design Considerations Northern Engineering Services, Inc Kechter Road Improvements ' December, 2001 III. PRE -DEVELOPMENT CONDITIONS 3.1 Major Basin Description The roadway improvements are located in the McClellands Creek Basin. According to ' the McClelland's Basin Master Drainage Plan, detention was required in the McClelland's Basin with a maximum 10-year release rate of 0.2 cfs/acre and a maximum 100-year release rate of 0.5 cfs/acre. The following quote from the Fossil Lake Second Filing Report dated May 3, 2001 t demonstrates that no detention is required. "In discussions with the City of Fort Collins, it was decided it would be better not to detain runoff from the site. Releasing the runoff immediately would actually lower the peak flow in the McClelland Drainageway downstream from the site." The Second Filing report goes on to say that the McClelland Drainageway SWMM model was updated for the developed conditions, which include the Kechter Road improvements. ' 3.2 Pre -development Drainage Patterns The existing drainage south of the roadway travels northeast until it is intercepted by a ' swale along the south side of the roadway. The flow is then directed east to McClellands Channel along the roadway under two existing driveways. At several locations the swale terminates and flow is conveyed in the roadway until the swale begins again. Drainage north of ' the roadway is conveyed away from the road, northeast, overland until it reaches McClellands Channel. There are two existing corrugated metal pipes (CMP) in the intersection of Kechter Road and Ziegler Road. The CMP's are used to convey irrigation flows associated with the irrigation ditches running along the east and west side of Ziegler Road and to convey drainage flows associated with approximately 235 acres west of Ziegler Road. The flows are conveyed to the property northeast of the Kechter Road and Ziegler Road intersection. The improvements to ' Kechter Road propose the removal or flow fill of the CMP's and replacement with larger reinforced concrete pipe. ' IV. POST -DEVELOPMENT CONDITIONS 4.1 Post -development Conditions The Kechter Road Improvements include the following: ' • Widening the existing roadway and adding vertical curb and gutter • Replacement of the existing CMP's at the intersection of Kechter Road and Ziegler Road. ' • McClelland Channel improvements as described and approved with Fossil Lake Second Filing Plans, including the box culvert. • 12" waterline installation across McClelland Channel • Water Quality Pond as approved with the Fossil Lake Second Filing Plans • Conveyance of irrigation flows across Kechter Road ' 4.2 Design Criteria and References Drainage criteria outlined in both the City of Fort Collins Storm Drainage Design Criteria Manual, (SDDCM), Storm Drainage Criteria Manual by the Urban Drainage and Flood Control District, the Final Drainage Study for Fossil Lake P.U.D. Second, Fort Collins Colorado dated May 3, 2001 and McClellands Creek Master Drainage Plan Updated, November 30, 2000 have been referenced for this study. Drainage Design Considerations Kechter Road Improvements December, 2001 Northern Engineering Services, Inc 4.3 Hydrologic Criteria The Rational Method has been used to estimate peak stormwater runoff associated with most delineated basins. The exception to the rational method is the 235-acre basin F2, which used a 10-year rate of 0.2 cfs/acre and 100-yr rate of 0.5 cfs/acre. These previous rates were agreed upon by the City of Fort Collins Stormwater Department on October 17, 2001 in a phone conversation. Furthermore the rates are supported by the McClellands Creek Master Drainage Plan Update. The 2-year, 10-year and major 100-year design storms have been used in the design of the proposed drainage system, which includes storm inlets, culverts and swales. Rainfall intensity data for the Rational Method has been taken from Figure 3-1 a updated by the City of Fort Collins in 1999. These rainfall intensities were used for the design of new improvements being proposed with the roadway. 4.4 Hydraulic Criteria The City of Fort Collins Storm Drainage Design Criteria has been referenced for all hydraulic calculations. In addition, the following computer programs have been utilized: • The computer program "UDINLET" has been used to analyze inlet capacities • The computer program "F1owMaster" has been used to analyze the swales and street capacities • The computer program HY-8 has been used to analyze the culverts 4.5 Drainage Patterns Runoff from basin F2 will flow through an existing swale system along the south edge of the Kechter roadway until it dumps into an existing ditch at the southwest corner of the Ziegler/Kechter intersection. Flow that enters the ditch will be conveyed, east, across Ziegler Road by three (3) 19"00" HERCP's. Then northeast in Swale 2 to three (3) 19"00" HERCP's which cross Kechter Road. On the north side of Kechter Road the flow will exit the HERCP drainage pipes and be conveyed in Swale 1 to McClellands Channel. All of the above -mentioned HERCP pipes have been designed to hand the 10-year flow. Basin F1 runoff flows overland until the existing irrigation ditch along the east side of Ziegler Road intercepts it. Until the ultimate build -out of Ziegler Road occurs the runoff, 2.5 cfs 10-yr, will flow through the rerouted irrigation system. Once the ultimate build out of Ziegler Road occurs the flow will be routed through the drainage system, not the irrigation system. The drainage system has been designed to handle the ultimate build out of Ziegler Road. After the ultimate build out has occured the runoff at Design Point F 1 will combine with the runoff from F2, to flow east.in a Swale 2, then north across Kechter Road in three (3) 19"00" HERCP's that have been design to handle the 10-year flow of 49.5 cfs. From there the flow will be conveyed in Swale 1 to the McClellands Channel. Both culverts for Basins F1 and F2 have been sized to handle the 10-year flows. In a 100-yr event, flow above and beyond the culverts capacity will be conveyed north in Ziegler Road to Sage Creek Road. Two existing sump -curb inlets at the PCR's in Sage Creek Road will intercept some of the flow and place it in the existing detention pond PB, built with Sage Creek. Pond PB drains into McClellands Channel. Flow that is not intercepted by the inlets will continue to flow north in Ziegler road until it reaches a low point in the road approximately 200- feet north of McClellands Channel. At the low point the runoff will be conveyed south in swales along the east and west sides of Ziegler Road until the runoff reaches McClellands Channel. 3 1 Drainage Design Considerations Northern Engineering Services, Inc Kechter Road Improvements December, 2001 Flow in existing basin E1 will be conveyed northeast overland to a swale along the south ' side of Kechter Road. Flow traveling east in the swale will be diverted to the street through a sidewalk culvert and chase prior to reaching the existing residence. From there the flow will travel east in the curb and gutter combining with flows from basins E2 and 1 as it travels. At the intersection of Kecther Road and Trilby Road the flow will follow the curve return and be deposited into the proposed Swale 7 of Fossil Lake Second Filing, then pass through Culvert 4 of Fossil Lake Second Filing into Water Quality Pond 1 of Fossil Lake Second Filing. Swale 7, Culvert 4 and Water Quality Pond 1 of Fossil Lake Second Filing are being constructed with the Kechter Road Improvements. Proposed runoff associated with Basin 2 will flow overland to curb and gutter, where it ' will be conveyed to Design Point 2. Design Point 2 will be a 15' inlet in the McClelland's Channel box culvert that has been sized to handle the 100-year flow of 18.9 cfs. Runoff from basin 3 will be conveyed overland to curb and gutter, upon which it will flow to a 5' inlet in the McClelland's Channel box culvert at Design Point 3. The 5' inlet has been designed to handle the 100-year flow of 8.9 cfs. 4.6 Irri atg ion As mentioned above the existing irrigation at the intersection of Kechter and Ziegler ' Road will be conveyed across Kechter Road. Irrigation flows in the ditch along the east side of Ziegler road will be routed east in Ditch D2 to a proposed 19"00" HERCP pipe under Kechter Road. The HERCP pipe will drain into a sump manhole that will act as the starting point for an inverted siphon to transport the irrigation flows west under the proposed Swale 1 in a 18" RCP pipe. Once the flow has crossed Swale 1 it will enter another sump manhole and exit at a higher elevation. This, second manhole, will act as the end of the inverted siphon. Flow will leave the second manhole in an 18" RCP and be conveyed west in Ditch D I to the existing ditch that runs north along Ziegler Road. Approximately 5 acres of existing agricultural land southeast of the Kechter\Ziegler intersection is irrigated during the growing season. The tail water for the irrigated land currently runs under two 12" driveway culverts to ditch, then to McClellands Channel. Due to expressed concern from the City of Fort Collins Engineering Department that the tail water entering the street will create maintenance problems, a drainage pipe has been placed under the sidewalk at the City's suggestion to alleviate any tail water problems. The pipe will connect the previously mentioned 5-acre field with Swale 7. Flow that enters the pipe will be routed through Swale 7 and Water Quality Pond 1, before entering McClellands Channel. The drainage pipe has been sized to handle the 100-year runoff of 5.8 cfs. This will provide adequate size for irrigation runoff and storm water. 4.7 Detention No detention is required as agreed upon in the Fossil Lake Second Filing Drainage report dated May 3, 2001. Water Quality Capture Volume will be provided in the form of Water Quality Pond 1, designed with Fossil Lake Second Filing, to be constructed with Kechter Road. 1 4 I Drainage Design Considerations Kechter Road Improvements December, 2001 Northern Engineering Services, Inc 4.8 SWMM Modelint? There will be no SWMM modeling performed as part of this Kechter Road drainage study. All SWMM modeling has been completed and approved by the City of Fort Collins as part of the Fossil Lake Second Filing P.U.D. V. WATER QUALITY 5.1 Water Quality Measures and Criteria Sizing for a temporary water quality pond will not be provided. The scheduled construction of Fossil Lake Second Filing, Phase 3 does not lag behind the Kechter Road Improvements long enough to justify a temporary water quality pond. Instead it is proposed that the final Water Quality Pond 1 designed with Fossil Lake Second Filing be constructed, thereby satisfying the long term needs of the area. The original design of Water Quality Pond 1 called for a standpipe structure. That design has been altered with this project at the City's request to use an orifice plate designed according to Urban Drainage standards. VI. EROSION CONTROL PLAN 6.1 Erosion Control Criteria The erosion control plan presented here is intended to control both wind and rainfall erosion. The Erosion Control Reference Manual for Construction Sites (ECRM), City of Fort Collins, has been referenced for this erosion control plan. 6.2 Rainfall Erosion Control Plan The proposed rainfall erosion control plan during construction will consist of temporary structural erosion control measures. Gravel inlet filters will be placed at all curb inlets. Straw - bale sediment traps will be placed at the entrances of all culverts. Silt fencing will be installed at the locations specified on the Grading and Erosion Control plan to prevent the migration of sediment. Straw -bale dikes will be place in the swales at a minimum spacing of 200-feet. All procedures listed under the City of Fort Collins Standard General Grading and Erosion Control Notes shall be strictly followed. It has been clearly noted on the Grading & Erosion Control Plan that no soils shall remain exposed for more than thirty days before requiring temporary or permanent erosion control measures, unless approved by the City of Fort Collins Stormwater Utility. The proposed erosion control plan after construction will consist of permanent riprap, which will be provided at the locations specified on the construction plans. All open space areas and grass -lined swales will be seeded with a permanent dry -land seed mix. VII. CONCLUSIONS 7.1 Compliance with Standards All drainage design considerations are in accordance with the City of Fort Collins Storm Drainage Design Criteria Manual (SDDCM), the Urban Drainage and Flood Control District's Drainage Criteria Manual and drainage design approved with Fossil Lake Second Filing.

The program was used to evaluate riprap needs for Swale 1. The largest recommended D50 was selected as the design riprap.

Using the allowable depths based on Tables 4-1 and 4-2 the theoretical street capacities were calculated with the computer program "F1owMaster v 5.13". A reduction factor from Figure 4-2 was than applied to the theoretical flow to give the allowable flow. The ' output is presented in the form of street cross -sections that progress through each design point as follows: 1. Minor Storm Theoretical Flow 2. Minor Storm Actual Flow ' 3. Major Storm Theoretical Flow 4. Major Strom Actual Flow ' The 100-yr flows at Design Points 2 and 3 have been combined due to overtopping. All street capacities were labeled acceptable based on depth requirements set fourth in Tables 4-1 and 4-2. Design point 2 did not meet the reduction factor flow for the minor and major storms, but depth and lane requirements were acceptable, based on that the street was pronounced acceptable. 1 F TABLE 4-1 NTIAL STORM - STREET RUNOFF ENCROACFNEhIT erreer LOCAL (Includes olaces. alleys No curb -overtopping. *Flow may spread to marginal access) crown of street.

The capacity of the pipe was analyzed with the program HY8. ' Based on the existing 49 LF of 18" CMP and a maximum ponding elevation of 16.82, the existing pipe can handle 10 cfs. The supporting HY8 documents follow. ' In addition to basing the design off of the existing culvert both downstream irrigation users have been contacted for input; ' A phone conversation with Paul Staley, downstream shareholder, on 12/20/01 at approximately 10:00 am took place. In this conversation the proposed rerouting of the irrigation flow was discussed. Paul mentioned that he typically runs 4 cfs through the system, but would like to get 8 cfs. He has been limited to 4 cfs because of the existing ditch and culvert, which have been in disrepair and sediment lading. The proposed ' system, including the siphon was explained as well as the flows. Paul agreed that the proposed flows and system would be acceptable and pointed out that the siphon may not be constructed do to the timing with the school property. The realignment of the ditch along the north side of Kechter Road would eliminate the siphon. This realignment is being designed by Nolte Associates. A phone conversation with Tom Brown, downstream shareholder, on 12/20/01 at 1:15 pm discussed the proposed system as wells as the flow amounts. As mentioned above Tom agreed that the existing culvert typically allowed for only 4-5 cfs in the past. The ' proposed system was explained, including the inverted siphon. Tom had no reservations about the layout and agreed that the design flow of 14 cfs was acceptable. The proposed realignment of the irrigation system will involve rerouting the existing ditch, southeast of the intersection, to line up with the proposed 19"x30" HERCP irrigation pipe crossing Kechter Road. From there the flow will travel east through an inverted siphon under the proposed Swale 1. Upon exiting the siphon the flow will enter Ditch D1 and be channeled back into the existing irrigation ditch that runs along the east side of Ziegler Road. The existing ditch runs north and crosses McClellands Channel in an existing 18" CMP flume. The proposed system has been modeled with Eagle Point Storm Sewer Module. The system has been designed to handle 14 cfs, which is above the expected irrigation flow of 8 cfs. Supporting documentation follows.
