Description
This is a basin initiative to fund the Maintenance of Watershed Parameters and Models element of the District's
Watershed Management Program (WMP) in Manatee County. This process will be applied to watersheds where the
parameters and model(s) were developed or updated based on the District's Guidelines and Specifications (G&S) and
where parameters from Environmental Resource Permitting (ERP) submittals can be converted to the District's GIS
system until a model is developed. Funding will be required each year to continue maintenance. With proposed
funding the work of capturing watershed parameter changes resulting from approved ERPs, and updates to
topographic, soils and land use information will continue throughout the District. The funding will also support the peer
review and public outreach process on the preliminary floodplain results, and presenting the results to Governing
Board for approval.
Benefits
A WMP provides a method to evaluate the capacity of a watershed to protect, enhance, and restore water quality and
natural systems, while achieving flood protection. The information developed assists local governments with their land
management responsibilities by establishing a level of service and developing Best Management Practices (BMPs) to
address level of service deficiencies. In addition, the information provides the District with the best available
information to evaluate adverse impacts and mitigation of floodplain impacts for proposed ERPs. The most up to date
information about the watershed will be available through the continuous maintenance of watershed parameters in the
GIS database: as ERP permits are approved, new information is provided to the District through aerial topographic
mapping and the public review and comment period. If a watershed model has not been developed, the maintenance
of parameters in the GIS processes the information in a format that will save time and funding when the watershed is
modeled.
Costs
For FY2010 the funding distribution for Manatee county is as follows: Governing Board $67,635 and Manasota Basin
Board $67,635. There is no revenue from Manatee County. The budget is based on the projected number of approved
ERP permits and the average development area within each Basin. Local government matching funds are equally
matched by Governing Board and Basin Board funds. The Governing Board is also providing funds specifically to
address public meetings and unforeseen issues with projecting the floodplains to be used in the FEMA mapping
process. Future funding to continue maintenance has been estimated through 2011. The projected annual funding
amount for Manatee County ranges from $200,000 to $250,000. The District funding amounts shown in the table
includes staff salaries.
Additional Information
A WMP includes five major elements: 1) Topographic Information, 2) Watershed Evaluation, 3) Watershed
Management Plan, 4) Implementation of Best Management Practices, and 5) Maintenance of Watershed Parameters
and Models. Implementing elements of the WMP with local governments is one of the District's Strategic Priorities.
After the Topographic Information, Watershed Evaluation and Management Plan elements are completed; the
watershed parameters and models require continuous maintenance to simulate the watershed's characteristics as the
land form changes. The watershed's parameters change with the continued growth experienced in the District. If
continued maintenance of the models is not performed, the watershed parameters and model will no longer represent
the system. This limits their value in the areas of ERP and flood protection programs. A revenue agreement will be
developed with each community contributing funds towards maintenance. The District will manage the project and
enter into purchase orders and agreements to accomplish project tasks. Future funding will be required each fiscal
year to continue maintenance of watershed parameters and models. In the future those local governments with the
technical abilities to perform the maintenance activities will be encouraged to manage this effort. The District will
provide funding assistance to communities that can and those that cannot provide matching funds. Matching funds will
be requested from the Federal Emergency Management Agency (FEMA) for this basin initiative. Failure to provide
ongoing maintenance will diminish the return on the investment the District has made in their respective Watershed
Management Plans.
