Box 580 Fort Collins, CO 80522 Dear Basil: On January 12, 1995, I surveyed the elevations of the floors and lowest openings of the residences constructed on lots 21, 22, 23 and 24 of Cobblestone Corners P.U.D. . The finish floor elevations on lots 21 and 22 are both 5092.68 and the proposed plan grade is 5092.5. The lowest openings of the basement window wells on lots 21 and 22 are 5091.25, and the detention pond high water line adjacent to these lots is 5087.00. The garage floors on lots 21 and 22 are at elevation 5089.24, compared to the plan grade of 5089.50. The elevation of 5089.24 maintains 1.04 feet of freeboard above the 100 year high water elevation of 5088.2 in the drain channel between lots 22 and 23. The finish floors of the duplex on lots 23 and 24 are 5091.18, compared to the plan grade of 5092.50. Lot 23 has no basement, and the window well on lot 24 is at 5090.1. The finish floor elevations and lowest openings are well above the maximum pond elevation of 5087.0 and the drain channel high water elevation of 5088.2. The garage floors on lots 23 and 24 are at 5089.60, compared to the plan grade of 5090.0. These garage floors are 1.4 feet above the 100 year high water elevation of 5089.2 in the drainage channel between lots 22 and 23. I have attached a blueprint showing the surveyed elevations in red. Please call if you need further information. Sincerely, Phillip I. Robinson, P.E. & L.S. Vice President rsc James H. Stewart and Associates, Inc. 103 S. Meldrum Street P.O. Box 429 Ft.
