The area map <br />provided indicates drainage areas and maximum stonn water flow to be generated from <br />the area based on a 10 year frequency stonn event. Areas are given in acres. <br /> <br />The flow rates, in cubic feet per second, are annotated to indicate the structure intended <br />to pick up the runoff. For example, Q6=11.4 indicates that a flow of 11.4 cfs is generated <br />from the area and picked up by structure 6. <br /> <br />Also included are the spread sheets showing the calculations for each run of storm sewer. <br />There are separate spread sheets for the northern and southern trunks respectively. The <br />MH/CB numbers on the spread sheets correlate to the numbers assigned to the structures <br />on the area map. <br /> <br />If you have any questions please give me a call. <br /> <br />Sincerely, <br /> <br /> <br />Enclosures <br />
