Basin 5 <br />encompasses an area of approximately 400:t acres and is delineated through the use of <br />the existing basin topography and the storm water runoff patterns to the ultimate basin <br />outfall known as West Lake. Land uses within the basin are primarily single and multi- <br />family residential; however, the US-l corridor is comprised of commercial, industrial <br />and office land uses. <br /> <br />The proposed drainage improvements consist of four duplex pump stations, more than <br />20,000 linear feet of higher capacity storm sewer to improve storm water conveyance, <br />more efficient discharge outfall systems and exfiltration trenches to improve area water <br />quality. The retrofitted drainage systems within the City Basin 5 drainage areas will <br />attenuate the storm water runoff and reduce the frequency and duration of flooding. <br /> <br />CGA developed the Storm water Master Plan for Basin 5 through modeling performed <br />using the Interconnected Channel and Pond Routing (ICPR) software. CGA evaluated the <br />existing and proposed Level of Service (LOS) of flood protection for the basin. Pre and <br />post improvement scenarios were modeled for the 10 year 24 hour, 25 year 72 hour, <br />and 100 year 72 hour storm events. Repetitive Loss properties are located within the <br />basin and were benefitted by the flood stage reduction; however, it was economically <br />impractical (due to extremely low finished floor elevations on some RL properties) to <br />attain an LOS which would have protected all habitable structures within the basin. <br /> <br />From the Master Plan CGA provided the City with a prioritized list of necessary <br />improvements, including projected cost, for inclusion in their Capital Improvement <br />Plan, <br /> <br />11-4620 Basin 5 Drain Daniabch <br /> <br />Client <br />City of Dania Beach <br /> <br />Contact Information <br /> <br />Dominic Orlando <br />Public Services Director <br />100 W.
