<br />Project Description I Scope of Work <br /> <br />The City of Sunny Isles Beach comprises a land area of less than 2 square miles located <br />between the Atlantic Ocean and the Intracoastal Waterway. The City is situated on a barrier <br />island with an average elevation of six (6) feet above mean sea level, and is particularly <br />vulnerable to flooding. <br /> <br />The current storm water drainage systems throughout the City vary from neighborhood to <br />neighborhood, most of the existing piping diameters are undersized (10" and 12") and in <br />many cases beyond repair. The existing collection systems designed to protect the City from <br />flooding are faulty, and are not in compliance with the required minimum FOOT standards on <br />flow and water quality. <br /> <br />These drains are decades old, and over time, sediment, leaves, and other debris have <br />collected in the pipes and gravel layer to the point of making them impermeable. This leads to <br />the drains backing up and water pooling on the surrounding pavement. <br /> <br />Because the piping system is beyond repair and no longer provides sufficient drainage, even <br />relatively moderate rain events can result in serious street flooding. This situation can be <br />compounded even more by tidal activity in the adjacent Bay. In addition to being a safety <br />hazard, flooding is also causing increasing damage to pavement in this area. <br /> <br />Sunny Isles Beach is currently in the planning stages of a storm drainage improvement <br />project in its Central Island area. The estimated cost of the project, which also includes <br />extensive road repairs, is approximately $5 Million. <br /> <br />Rather than trying to overhaul the existing substandard system, Engineers have proposed a <br />completely different means of handling the storm water. Deep wells of over 100 ft. deep will <br />be drilled. Storm water will flow into these wells, and the static pressure of the water will <br />force it into the bedrock layer beneath the City, where it will be diffused. Part of the system <br />includes buffers in some of the drain units for preventing the bedrock layer from getting <br />gummed up with debris. <br /> <br />Engineers estimate that if the system is properly maintained, it can provide effective drainage <br />indefinitely. Also, this system design is a proven one; the City has already completed a <br />similar, smaller-scale project in the Golden Shores neighborhood north of the City which has <br />been very effective. <br /> <br />SIB <br />
