Recommendation
Fund as a Medium priority. This proposed funding request is for the implementation of a Stormwater Improvement Project(BMP) for
the Holloway Road Improvement Area. In addition, land may needed in order to prevent further erosion along the conveyance way,
no construction permit has been acquired for the proposed project, and no water quality enhancement is proposed, therefore the
project is ranked as medium.
Description
This is a proposed multi-year funded project to perform the implementation of Best Management Practices (BMPs) element of the
District's Watershed Management Program (WMP) in the Alafia River Watershed. This proposed BMP will be implemented in the
Holloway Road Improvement Area. The issue in this improvement area is the flooding of Holloway Road and severe erosion along
several maintenance access creek crossings along the TECO High KV powerline that the conveyance system traverses. The
proposed conveyance system improvements includes replacing and upgrading existing 36 inch culverts with two 4'x4' RCBCs
under Holloway Road, replacing and upgrading the existing culverts under the TECO maintenance access roads and regrading the
existing channel system along Grassy Creek that is a northern tributary to the Alafia River. The project would includes PD&E and
that possibility that land acquisition may be required. The adjacent subdivision has reported flooding in the past and the erosion
along the TECO access roads is considered an issue for homeland security according to the County. Implementation of BMPs
includes the following tasks: design, development of construction documents, construction permitting, land acquisition, bidding
and contractor selection, construction of the BMPs and construction engineering and inspection. The proposed BMPs will address
level of service deficiencies. Implementation of BMPs includes the following tasks: design, development of construction
documents, construction permitting, land acquisition, bidding and contractor selection, construction of the BMPs and construction
engineering and inspection. The proposed BMPs will address level of service deficiencies.
Benefits
The proposed BMPs will reduce street flooding and residential flooding along Holloway Road.
Costs
The total budget amount for this project is $1,300,000 of which the District’s share is $650,000 and the County share is $650,000.
For FY2013, the County has requested $150,000 in District funding for BMP alternative analysis (PD&E). The County will contribute
$150,000 matching funds. Future funding will be needed to complete the project. When each element is completed the project
budget may require refinement. The probable costs for this project are based on an estimate developed by the cooperator. The
District funding amount shown in the table includes staff salaries.
Additional Information
The WMP includes five major elements: Topographic information, Watershed Evaluation, Watershed Management Plan,
Implementation of BMPs, and Maintenance of Watershed Parameters and Models. The Alafia River watershed management
master plan study was completed in 2001 and updated in 2010. TC-2/WQ, Turkey Creek Surface Water Treatment Area, is one of
the projects to be implemented that was identified in the study. Implementing elements of the WMP with local governments is one
of the District's Strategic Priorities. A cooperative funding expenditure agreement with Hillsborough County will be developed as a
multi-year funded project contingent on the approval of future funding to complete the Implementation of BMPs. This is a
multi–year funded project that will require a cooperative funding request each fiscal year until completed. The County will manage
the project, where the District project manager must approve any agreements to accomplish project tasks. The County has asked
that the District co-fund the PD&E on this project. Land acquisition may be required and there have been no permits issued to
date.
