Box 580 Fort Collins, Colorado 80522 Dear Basil: The following drainage and erosion control report is prepared for the Horsetooth East Business Park Minor Subdivision. Horsetooth East Business Park Minor Subdivision is the second phase of a 32.2 acre business and industrial development which was begun in 1991. A drainage report titled "Horsetooth Business Park First Filing" was prepared for this 1991 development. I am including a copy of this report in the appendix and will follow the design guidelines established by this 1991 report. This report complies with the City of Fort Collins Storm Drainage Design Criteria. Sincerely, Phillip I. Robinson, P.E. & L.S. Vice President I J 4502 jrr enclosures James H.

FINAL STORM DRAINAGE AND EROSION CONTROL REPORT HORSETOOTH EAST BUSINESS PARK MINOR SUBDIVISION SITE LOCATION The Horsetooth East Business Park Minor Subdivision is located in the Fox Creek Drainage Basin. The site is the southerly 8.9 acres of a 32.2 acre development located in the Northeast '—, of Section 31, Township 7 North, Range 68 West, of the Sixth P.M., City of Fort Collins, Colorado. The site is bounded on the west by the Union Pacific Railroad, on the north by Bighorn Drive, on the east by Timberline Road, and on the south by the Collindale Business Park. Automation Way runs north —south through the approximte middle of the site. EXISTING CONDITIONS The site drains from northwest to southeast at 0.7 percent slope. The site is covered with heavy vegetation consisting of broad leaf grass. There is a dirt stockpile on the westerly portion of the site, and there is a wetland ponding area in the southeast corner of the site (Tract A). This ponding area will be utilized as a detention pond for the east half of the site (Lots 1 and 2). There is an existing detention pond located along the north boundary of the west half of the site (Lot 3). This pond was constructed by the Horsetooth Business Park First Filing in 1991. Lot 3 will not be developed at this time and will be left as is. The existing vegetation on Lot 3 will not be disturbed. OFFSITE FLOWS There are no major offsite flows onto the three lots of Horsetooth East Business Park. The east one—half of the Union Pacific railroad right—of—way drains onto Lot 3, but the railroad embankment stops flows from the Collindale Golf Course which lies west of the railroad. There is an open irrigation ditch across the south edge of the site. This open ditch picks up runoff from the golf course and from the railroad right—of—way. The ditch is piped under the railroad by a 24—inch steel pipe, and then runs east in an open ditch to Timberline Road where it enters a 24—inch diameter concrete pipe and is then piped on east to County Road 9. We plan to place this open ditch in a pipe from Timberline Road to the west side of Automation Way. This shall require approval of the ditch co—owner, Mr. James C. Gleason. PROPOSED STORM DRAINAGE DEVELOPMENT The existing ponding and wetland area located on Tract A will be utilized as the detention pond for Lots 1 and 2 and the adjoining Big Horn Drive and Timberline Road. The total area draining into the ponding area will be 4.82 acres. Lot 1 will be developed at this time with an office building and parking lot, and Lot 2 will be developed in the future with a building and parking lot. A schematic plan of the proposed Lot 2 development is shown on the utility and drainage. plan. We will provide, with the phase one construction of Lot 1, the required detention ponding and drainage facilities for a developed Lot 2, so that when Lot 2 is constructed in the future, it can drain directly into the detention pond. Horsetooth East Business Park Minor Subdivision Page 2 Lot 2 will remain a grassed field until construction takes place. Any overflow from the detention pond onto the undeveloped Lot 2 will be onto the grassed field, and will be acceptable since it will recede back onto Tract A. After construction of the curbs and parking lots on Lot 2, the detention pond will be confined to Tract A by the filling required for the curb construction. There will be no development on Lot 3 at this time, and in the future when Lot 3 is developed, the existing detention pond along the north boundary of Lot 3 will be enlarged to supply detention necessary. The natural flow direction of Lot 3 to the southeast will be changed by filling and by piping so that it drains to the north and northeast into the detention pond area. A separate drainage report shall be necessary for the development of Lot 3. The release rate for the 4.82 acre development of Lots 1 and 2 and Tract A is 0.17 c.f.s. per acre, per the 1991 Horsetooth Business Park report. The release rate from the Tract A pond shall be 0.82 c.f.s., and the required pond volume shall be 41703 cubic feet. Release from the Tract A pond will be through a 15—inch pipe with a restricted opening. This restriction plate shall be the "flap gate" type, as utilized by the Horsetooth Business Park First Filing, to allow backflow from the 15—inch storm pipe system to flow into the detention pond. This reason for this backflow is to allow street flows to enter the detention ponds via the catch basins and then by backflow through the pond outlet pipes. EROSION CONTROL Horsetooth East Business Park is located in a moderate rainfall and wind erodibility zone. Lot 1 will be developed at this time, and Lots 2 and 3 will be developed in the future. The existing heavy grass vegetation on Lots 2 and 3 will not be disturbed at this time. Tract A is on existing wetland ponding area which will be utilized as the stormwater detention area for runoff from Lots 1 and 2. A restrictd outlet from the pond will be protected by a sediment trap. The construction sequence will be that the building foundation will be constructed this fall and winter and, weather permitting, the curbs and pavement will follow. If it is impractical to begin the curb and pavement due to weather, the building construction can still proceed, and the existing vegetation on the parking lot area of Lot 1 can remain undisturbed. The erosion control procedures shall comply with City of Fort Collins criteria. 0 COL. LINOALE GOLF COL,RSE u VICINITY MAP 0 a i 4 O l STE V VART&&SSOCIATES 103 S.

REYNOLDS COMPANIES PREPARED BY STEWART & ASSOCIATES, INC. FEBRUARY 4, 1991 REVISED 3l16�9/ REVISED 4f/ c VICINITY MAP COLLINOA'E GOLF COURSE LOCATION: The Horsetooth Business Park is located on the southwest corner of Horsetooth Road and Timberline Road. The property is bounded on the north by Horsetooth Road, on the east by Timberline Road, on the west by the Union Pacific Railroad, and on the south by Collindale Business Park. The total Horsetooth Business Park contains 32.2 acres. The Horsetooth Business Park First Filing is located at the northwest corner of the site, adjacent to the Union Pacific Railroad, and contains a gross area of 10.38 acres to the center of adjoining streets. Horsetooth Business Park is located in the Foothills Drainage Basin. Portions of the site have been previously platted as South Collins Tech Center First, Second, and Third Filings. EXISTING CONDITIONS: The pavement, curbs, and sidewalks on Horsetooth Road are completed, and portions of the pavement, curb, and sidewalk on Timberline Road are constructed. Some of the utilities, pavement, curbs, and walks shown on the South Collins Tech Center First Filing plans have been installed, although a part of these improvements do not fit the present plan, and will be removed. Other than the previously installed streets, the site is a pasture covered with vegetation. There are no offsite flows onto the site. There is an irrigation ditch which flows from west to east across the south edge of the site. This ditch belongs to Mr. Bob Shields, and delivers water from Warren Lake to sites east of Timberline Road. This ditch is open from a point on the west side of the Union Pacific Railroad to the west side of Timberline Road, and picks up historic surface flow from the railroad right—of—way, along with some run—off from the Horsetooth Business Park site. We anticipate that in the future this ditch will be put in a pipe from Timberline Road to the east side of the Union Pacific Railroad, and that it will still carry historic surface run—off from the railroad right—of—way. PROPOSED IMPROVEMENTS: The Horsetooth Business Park First Filing consists of 10.38 acres, 7.93 acres of which are to be impervious. We plan to provide stormwater detention for the difference between the 2 year historic runoff and the 100 year developed runoff. This calculates to be 2.21 acre feet of detention. There will be a small detention pond located in the parking lot at the northeast corner of the site, and a large detention pond located along the south side of the site. The maximum allowable outflow from the total 32.2 acres of the Horsetooth Business Park site is 5.5 c.f.s. The 5.5 c.f.s. outflow is determined by the available capacity of the existing 24 inch pipe under Timberline Road. The 24 inch pipe was installed in 1989 as a part of the Foothills Drainage Basin major improvements, its purpose being to carry storm flows from the Collindale Business Park and from the Horsetooth Business Park. The allowable.outflow per gross acre of the Horsetooth Business Park is 5.5 divided.by 32.2, equals 0.17 c.f.s. per acre, therefore the total outflow from the 10.38 acre site is 1.76 c.f.s. Sheet 1 Horsetooth Business Park, First Filing April 4, 1991 Page 2 We propose to use 15 inch RCP storm drains for all the pipes in the Horsetooth Business Park. Sheet 12 of this report is a profile of the proposed storm pipe system. Also shown on sheet 12 is the calculated hydraulic grade line, along with calculations of pipe flow velocity and capacity at critical points. We calculated all of the velocities and capacities in the pipe system based on the pipe outflow going into a completely filled Collindale Business Park detention pond. This is the most conservative situation, since the high water line elevation of the Collindale Business Park pond will be lower for all storms except the 100 year storm, and even during the 100 year storm, it will not reach the full level for 3 hours. The calculated capacity of the outfall pipe as it enters the Collindale Business Park pond is 5.3 c.f.s., which is close enough to the 5.5 c.f.s. allowable release rate. The hydraulic grade line is a maximum 0.22 feet above manhole lids, which is not enough to pop the manhole lids. There is a safety valve built into the storm pipe system, which is that when there is more runoff entering the pipe system through street catch basins than the downstream pipes can carry, there will be backflow into the detention ponds. Detention ponds constructed in the Horsetooth Business Park shall have an outflow restriction plate which is hinged, so that it will allow backflow to enter the pond through a 15 inch opening. Sheet 13 of this report shows the detention ponds for this filing, along with the approximate location, size, and high water line of future ponds. The small detention pond located in the north parking lot will provide 14,594 cubic feet of the total required 96,433 cubic feet of detention volume. The outflow from the small pond is 0.57 c.f.s., of the allowed 1.76 c.f.s., therefore, the outflow from the large pond located at the south end of the site will be the difference, which is 1.19 c.f.s. The proper volume will accumulate in the north detention pond due to the fact that we have used the 0.57 c.f.s. release rate and the basin area of 1.9 acres to calculate a detention requirement of 14608 cubic feet, which is substantially the same as the maximum pond volume of 14594 cubic feet. This release rate of 0.57 c.f.s. is larger than the allowable (1.9) (0.17) = 0.32 c.f.s., but we have compensated for this by decreasing the release rate of the south pond from (8.48) (0.17) = 1.44 c.f.s. to 1.19 c.f.s. The large detention pond located at the south end of the site has a proposed capacity of 110563 cubic feet, and a required detention volume of 81839 cubic feet, so there is 28724 cubic feet excess capacity. The bottom of this pond is to be left flat so that it will become a wetlands, with cattails and wetlands grasses. The wetland will become an effective settling basin and will provide a better water quality into the storm drainage system. The restricted outflow of 1.19 c.f.s. will slow the flow through the pond and allow the wetland settling area to be more effective. Sheet 2 Horsetooth Business Park, First Filing April 4, 1991 Page 3 There will be additional detention ponds constructed as more of the Horsetooth Business Park is developed. These additional ponds will be tied into the 15 inch outfall pipe line. The allowable release rate for all of the future parcels to be developed in the Horsetooth Business Park shall be 0.17 c.f.s. per gross acre. There is an existing 18 inch storm drain running east from the manhole at the intersection of Automation Way and Elk Road. This 18 inch line flows to the east and is part of a previously proposed system which will possibly be abandoned, therefore we are plugging the 18 inch pipe in the manhole and outflowing the manhole via a new 15 inch pipe draining to the south. The attached computation sheets show how we arrived at the allowable outflow, required detention volume and volume of the detention ponds. The attached grading and drainage plan shows the proposed grades and drainage facilities. Phillip V Robinson, P.E. & L.S. *e 4502 Sheet 3 F& COMPUTATIONS Stewart & Associates, Inc. 214 N.
