-2- <br />See attached culvert design sheet for culvert recommendation as follows: <br />* 1) Flameburger entrance crossing i 18" CMP with aprons <br />* 2) Culvert replacement for existing 12" CMP at east edge of Lot 5 j <br />24" CMP with aprons* <br />* 24" CMP should begin west of eastern property line and carry <br />drainage past 65 Demont Avenue west. This run could be <br />reduced in length if the ditch was reworked at 65 Demont <br />Avenue and the downstream driveway culvert was increased <br />to a 24" CMP. <br />3) Contractors working within this area should be more attentive to <br />controlling erosion within construction areas - filling of the <br />existing ditch is lessening already insufficient downstream capacities. <br />4) Further downstream ditching and culvert upsizing is needed (storm <br />sewering from Rice to Jackson is best solution). <br />JET /clm <br />8/6/81 <br />24 <br />
