Based <br />on our review, we would offer the following comments: <br /> <br />1. <br /> <br />The information we reviewed consisted of a preliminary plat and a preliminary <br />Grading Plan, both prepared by John Oliver and Associates and dated November 9, <br />1993. <br /> <br />2. <br /> <br />Generally, it appears that all building sites are set too low. The Grading Plan <br />indicates a curb grade of 0.50% from the back of the cul-de-sac. This would be an <br />absolute minimum grade to eliminate the potential for birdbaths during street <br />construction. However, when this grade is run back from the catchbasin shown at <br />the low point, the actual top of curb elevation at the rear of the cul-de-sac appeared <br />to be approximately 0.5 feet higher than shown. This is consistently true around the <br />entire length of the curb line. Having the curb actually higher than shown on the <br />Grading Plan would mean that house elevations should also be raised. <br /> <br />3. <br /> <br />The drainage on the south side of the plat shows rear yards which drain directly <br />across Lot 9. The Grading Plan should be reviewed in this area to keep rear yard <br />drainage within the designated easement areas. <br /> <br />4. <br /> <br />It is not clear where the drainage flowing off the lots on the northerly side of the plat <br />ends up. No topography is shown for those lots in Heritage Landing 1st Addition <br />which abut this development. Additional topography and drainage arrows should be <br />added to show where the drainage from Lots I through 4 will end up. <br /> <br />lTI-1803.apr <br />
