Silver Lake Road Flooding Analysis Results <br />May 03, 2017 <br />Page 3 <br />Model Results <br />Based on the XPSWMM modeling preformed, the following conclusions are made: <br />1. The flooding is a result of the direct drainage area to the low point on Silver Lake Road. <br />2. The existing conditions do not provide adequate inlet capacity to allow the water in the street to enter <br />the storm sewer pipes. <br />3. The existing conditions to not provide adequate storm sewer capacity to allow the water in the <br />streets to enter the storm sewer pipes. <br />Project Cost <br />The total project cost is estimated to cost $624,197.
