I't- <br />¥ <br />"r.i-. <br />L'i- <br />J: <br />W <br />i' <br />vi4 <br />I ^,. <br />0 <br />'; ’ <br />fj. <br />As per the direction of the City Coui.cil, we have made <br />a study of the Kelly Avenue area for the purposes of deter­ <br />mining the causes and possible remedies of the periodic <br />flooding situation for the purposes of making recommendations <br />for the alleviation of this problem. At present, a total <br />land area of approximately 46 acres is drained by a tile <br />system to Carmen Cove. Roughly 9 of these 46 acres drain <br />djy^gtly to the tile system, while the runoff from the re— <br />mainirg 37 acres must pond in the marsh area adjoining Kelly <br />Avenue to the east. This marsh area has the capability of <br />atoring roughly 2.75 acre feet of water. When this storage <br />capacity is exceeded, the marsh overflows across Kelly Avenue <br />to the drain tile system <br />Since the present situation exists because 1) there is <br />no effective outlet for surges in flow voltimes; and 2) the storage <br />capacity of the marsh is inadequate to prevent flooding; the <br />alternative solutions would be: <br />1) Construction of an adequate outlet to remove <br />excess runoff; or <br />2) Increase the storage capacity of the marsh; or <br />3) Decrease the runoff quantity <br />Alternate No. 3, the decreasing of the runoff quantity <br />is not feasible since the predominant land uses in the <br />drainage area are residential and undeveloped.
