Mr. Steve Ach <br />November 20, 1996 <br />Page Three <br /> <br />The drainage calculations for the plat should consider the runoff at the north <br />part of the plat which appears to be held in a depression. This area needs to <br />be checked to ensure that there is adequate capacity, such that none of the <br />homes will be threatened in the case of a severe runoff event. <br /> <br />The rear yard storm sewer shown in Block 3 appears not to be necessary. <br />We would prefer that catch basins not be provided in the rear yard because <br />they are hard to maintain. If necessary, a stub to the north could be provided <br />from the catch basin in the street and a flared end provided to pick up the <br />rear yard drainage. <br /> <br />Somewhere between 193rd Avenue and Quinn Court along Highland Street, <br />it appears that the 942 contour is missing. <br /> <br />The rear yard drainage along Lots 5-9, Block 4, needs to be provided with <br />side yard swales. As is now drawn, the drainage would shoot through these <br />lots. <br /> <br />The Developer of this plat will need to coordinate with the Developer of <br />Lafayette Woods along the west and north boundary to ensure that the <br />grading of the two plats is consistent. <br /> <br />If you have any questions regarding any of these comments, please call. <br /> <br />Sincerely, <br /> <br />MSA, CONSULTING ENGINEERS <br /> <br />TJM:pd <br /> <br />2301348-1907. nov <br /> <br /> <br />
