Dear Sirs: On February 24, 2005, we observed the site located at 3615 Wild View 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 grading appears to generally conform to the Final Grading Plan (Sheet 16 of 56) as prepared by Northern Engineering Services, Inc., dated 1/10/03, with a few minor exceptions. The finished floor elevation given by Absolute Surveying is 94.57 feet, which is approximately 1.43 feet higher than the design top of foundation elevation of 93.14 feet. Based on the northwest property corner, all lot corners are within 0.25 feet of design elevation, assuming the northwest property corner has a design elevation of 90.22 and assuming the southeast and southwest surveyed spot elevations are similar to the designed property corners. Northern's grading plan shows a swale behind the building that will divert the runoff to the swales located on both side lot lines. The swales have been constructed; however, the fall from the grade adjacent to the house to the high point in the swale is only 0.33 feet compared to the design fall of 0.5 feet. Also, the design slope of the swales were at 2 percent and the constructed slopes are approximately 0.8 percent. The site appeared to drain away from the building. In general, the north side of the house drains directly towards Wild View Drive. The other sides of the house drain to side yard swales which drain to Wild View Drive. 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. If you have any questions, please contact me at the above address or phone number.
