Box 580 Fort Collins, CO 80522 Dear Basil, ' The following is the Final Drainage Report for Sunol Acres which is situate in the Northwest 1/4 of Section 33, Township 7 North, Range 68 West of the Sixth P.M., City of Fort Collins, County ' of Larimer, State of Colorado. The site contains 5.1616 acres and is a replat of Lot 1 Strobel M.R.D. The site will be divided ' into 4 large lots. It is zoned Urban Estate. Lot 1 has an existing residence and Lots 2 thru 4 will have single family residences constructed. ' The site is bounded on the West by County Road 9, on the North by two metes and bounds large lots that are not in the City of Fort Collins, on the East by Lot 2, Strobel M.R.D. which is also not in the City and on the South by Charlie Lane which is annexed but has not been hard surfaced. The Christ Fellowship Church Subdivision, that is being reviewed by the City of Fort Collins, is on the South side of Charlie Lane. ' The site slopes from the Southwest corner to the Northeast corner at an approximate slope of 0.8%. The ground cover of the site is alfalfa except for the yard and gravel driveways of Lot 1. ' The Lot 1 ground cover will not be disturbed. The ground cover on Lots 2 thru 4 will not be totally disturbed in order to construct the residences due to the large area of the lots. ' The historic site has two sub -basins. H.B.-1 is the East half of County Road 9 which drains into a small borrow ditch which flows North to West Horsetooth Road. H.B.-2 is the remainder of the site. It sheet flows to the Northeast corner of the site and then on Northeasterly to the Fossil ' Creek Reservoir Inlet Ditch. The developed site is also divided into two sub -basins. D.B.-1 is also the paved part of the County Road 9 right-of-way which will drain North in the proposed curb and gutter to the existing borrow ditch on the property lying North of Sunol Acres. There will be some widening of the pavement to the East curb when it is constructed. The runoff continues to flow North to Horsetooth ' Road. D.B.-2 is the remainder of the site. The area of D.B.-1 is 0.27 acres and the area of D.B.-2 is 5.58 acres. 1 James H. Stewart and Associates, Inc. 103 S. Meldrum Street • P.O. Box 429 • Ft. Collins, CO 80522 970/482-9331 • Fax 970/482-9382 J ' It is planned to provide on site detention for D.B.-2 in the Northeast corner of Sunol Acres. A drainage easement will be dedicated on Tracts "A' and "B" for the detention pond. A drainage easement is being acquired from the owners of Lots 2 and 4, Strobel M.R.D. to carry the storm water from the pond, East to the Fossil Creek Inlet Ditch at the historic rate of 1.23 ' cubic feet per second. The 15 inch A.D.S., N-12 storm pipe is designed to carry the developed 100 year discharge rate of 8.54 c.f.s. if the outlet of the pond is plugged. The outlet structure from the pond is an area inlet. The upstream side of the inlet has a restriction plate that meters the discharge ' into the area inlet. If the orifice is plugged, the pond will fill and the spillway is on the top of the area inlet, allowing the discharge to flow into the inlet grate and flow out the 15 inch A.D.S. storm drain ' at the flow line of the inlet box. A copy of each easement is enclosed in this report. The detention volume required is 15,804 cubic feet. ' EROSION CONTROL The site is in the moderate rainfall erodibility zone and in the moderate wind erodibility zone. ' The site has a good ground cover of alfalfa that will not have over lot grading done on the entire site. Charlie Lane is an existing gravel road that will have curb and gutter constructed and then be paved. Straw bale dikes will be installed'in the existing.borrow ditches at the East end of Sunol Acres. A ' straw bale dike will also be placed at the outlet of the detention pond during construction of the pond. The pond will be reseeded after the grading is completed for the pond. A silt fence will be constructed along the North and East lines of the site. 1 The grading plan and the storm water runoff calculations and the erosion control calculations are enclosed as a part of this report. This drainage report and the design of the drainage stystem are in compliance with the City of Fort Collins Storm Drainage specifications and criteria. If you have any questions regarding this ' report, please call. Sincerely, I li�'.ow� a• y�`�V�.��,G1STEhy�iQ�eQ Richard A. Rutherford, FI.E. & L.S.

The subdivision is four large lots on Charlie Lane at County Road 9. The lots average 1.25 acres.

The lots have ' good existing ground cover which will not all be disturbed during construction. The length of the outfall grass swale is about 800 feet.
