LOT GRADING CERTIFICATION LETTER October 1, 2004 Jay Barber City of Fort Collins Stormwater Utility Department 700 Wood Street Fort Collins, Colorado 80521 Subdivision: Fossil. Lake P.U.D. First Filing. Lot Number: 4- Block Number:.10 STORMWATER RECEIVED OCT 15 2004 Address: 6583 Rookery Road Fort Collins; Colorado, 80528 Surveyed By: Northern Engineering Services, Inc. Date of Survey: 09/28/04 Fort Collins Benchmark(s): Temporary Benchmark - Back of Walk at SW Comer of Lot Dear Mr. Barber: On behalf of our client, Mr. Dean Dahlberg, we would like to submit to you a lot grading certification letter for Lot 4, Block 10 of the Fossil Lake P.U.D. First Filing project. This lot was constructed with a two-story, stone & wood, single-family residence with a walkout basement. Northern Engineering has reviewed the as -constructed elevations provided by a field survey crew. The residence on Lot 4 was constructed with a finished floor elevation of 4905.70 and a minimum opening elevation (MOE) of 4895.60. The proposed minimum top of foundation elevation for this lot was 4904.5. While the Engineer does not have knowledge of the constructed difference between finished floor and top of foundation, it is safe to assume that the actual top of foundation is at or above the approved elevation. Attached for your convenience are copies of the approved grading plan, detention information, and a copy of the Improvement Location Certificate showing the as -constructed elevations (handwritten) for Lot 4. Based on the surveyed grades, the lot appears to be in compliance with the approved grading plan. Sufficient fall exists away from the building to provide proper drainage. The high points on the side lot lines make the lot function as a `B' lot per plan. Lot 4 is west of Detention Pond 2. The designed 100-year water surface of this pond is 4890.84. Therefore, there is approximately 4.76-fi of freeboard from the pond's high water line to the MOE of Lot 4. 420 SOUTH HOWES, SUITE 202 / FORT COLLINS.
