Second Filing, City of Fort Collins, County of Larimer, State of Colorado (aka 3538 Long Creek Drive). Dear Sirs: On August 15, 2005, we observed the site located at 3538 Long Creek Drive. The site had been final graded. In addition to our observation, Absolute Surveying obtained spot elevations at numerous spots throughout the site. Please refer to the attached elevation sheet. Based on our observation and the attached survey information, the site appeared to drain away from the building.. In general, the west side of the house drains westerly towards Long Creek Drive and the east side of the house drains easterly to Outlot I. The south side of the house drains southerly to the small swale between the two lots. The north side of the house drains northerly to the small swale between the two lots. For the south side of the house, the high point elevation is in the middle of the southwest comer and southeast corner of the house. For the north side of the house, the high point is near the northwest corner of the house. At the high points, there is a gradual change in grade, as the design contours show. The finished floor elevation given by Absolute Surveying is 98.60 feet, which is approximately 0.9 feet higher than the design elevation (97.7 feet). Based on the southwest property corner, all lot corners are within 0.8 feet of design elevation, assuming the southwest property corner has a design elevation of 95.6 and assuming the northeast and northwest surveyed spot elevations are similar to the designed property corners. The site generally appears to conform to the Drainage Plan — Sheet 14 & 16 of 58 — of Fossil Lake P.U.D., Second Filing — prepared by Northern Engineering Services, Inc., dated 4/30/01. Also, the site generally appears to conform to the Grading and Erosion Control Plan — Sheets 8 & 10 of 58 — of Fossil Lake P.U.D., Second Filing — prepared by Northern Engineering Services, Inc., dated 4/30/01. Our certifications were based on our observation on the date noted above. The geotechnical report was not provided to us for this site. We therefore cannot determine if the site has been graded according to the geotechnical report.
