Flood Protection: The principal purpose of Hillsborough County’s floodplain management program is to protect residents and business owners from flooding risks. Flooding disasters are the leading recurring hazard within the County and have the potential of affecting greater than one-quarter of the population at a value that is greater than five billion dollars in personal property. Construction standards and planning concepts are implemented through the County’s Land Development Code, Floodplain Management Plan and Local Mitigation Strategy.

The continuous erosion caused by a combination of stormwater discharge, groundwater and by wave action has caused environmental damage to the existing seagrasses and mangroves. There are seven existing stormwater discharge pipes that collect runoff from a 113.27 acre tributary. The storm outfalls discharge through the bluff side banks about midway up the slope causing severe erosion of the bluff banks and at the toe of the bluff. The existing storm outfalls are also undersized causing upstream localized flooding and have very high velocities through the outfall pipes. The is to capture the runoff currently discharging through seven storm outfalls into a single storm pipe and directing all the runoff to one outfall location (see attached exhibits). A baffle drop box with a sump is proposed to dissipate the energy and reduce the velocity at the outfall thereby eliminating erosive discharge velocities and allowing for sediements to settle out within the box, which will be removed by routine maintenance. The segment of pipe from the baffle box to the bay will also be lowered so the pipe invert is slightly above the bottom of the bay in order to futher reduce erosion. The bluff banks around the new outfall will be stabilized with rubble rip-rap. The existing storm outfalls will then be removed, abandoned or capped eliminating erosion and sedimentation at those locations. This improvement will provide significant benefit to the existing seagrasses and mangroves along the shoreline and will eliminate localized flooding in the upstream areas. Also, a conservation easement has been obtained to protect the seagrasses and mangroves along the shoreline (see attached document). This is a request to provide the second and final year funding (FY2014) for the Bayshore Drive Drainage Improvement project (N434). The Town was previously approved for a cooperative grant in FY2010 (Agreement No. 09C00000068) in the amount of $5M to provide the environmental and flood protection benefits listed above. Under the original grant, the proposed improvements consisted of stabilizing approximately 2,700 linear feet of the bluff bank. Due to the economic conditions, the Town elected to revise the design in order to reduce the overall cost to under $2M while at the same time providing improved habitat, water quality and flood protection benefits for the area. In 2011 the project scope was modified with a final estimated total cost of $1,740,000. The Town submitted a cooperative funding application for FY 2012 for an amount of $1,740,000 of which the Town and District would fund equally at fifty percent each. The request was approaved and based on the project schedule and cash flow needs, a total first year funding amount of $800,000 was approved for FY 2013. The request for $940,000 in FY 2014 represents the remaining project costs. 37
