Dear Sirs: On September 20, 2004, we observed the site located at 5968 Snowy Plover Court. 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 surveyed information, the site appeared to drain away from the building. In general, the west side of the house drains westerly towards Snowy Plover Court and the east side of the house drains easterly to a concrete channel east of the lot. The north and south sides of the house drain northerly and southerly, respectively, to very shallow and wide swales that direct flows either westerly or easterly, depending on the high point location. For the north side of the house, the high point elevation is near the northeast corner of the driveway by the retaining wall. For the south side of the house, the high point is near the southwest corner of the house. At the high points for the north and south sides of the house, there is a sharp change in grade, as the design contours show. As the design shows, the back of the lot drains at a much flatter slope than the front of the lot. The finished floor elevation given by Absolute Surveying is,94.13 feet, which is approximately 2.14 feet higher than the design top -of -foundation elevation (91.99 feet). Based on the southwest property corner, all lot corners are within 0.31 feet of design elevation, assuming the northwest property corner has a design elevation of 89.64 (which is difficult to read on the grading plan), and assuming the northeast and southeast surveyed spot elevations are similar to the designed property corners. The house in Lot 21 located north of this site was still under construction. The construction was in a preliminary phase for the house in Lot 23 located south of this site. Our recommendations 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.
