Description
Sarasota County Environmental Services is creating and maintaining a comprehensive Geographic Information
System (GIS) database to support surface water modeling and stormwater asset management functions. This project
enhances the quality of the data supporting modeling activities by gathering accurate locations and characteristics of
key stormwater assets. Among many potential applications, these data will aid in the development and management of
watershed management plans through hydrologic model maintenance/updates and point and non-point pollutant
source identification. The funding will be used to enhance the County's current stormwater infrastructure database that
consists of control structures, inlets, pipes, pipelines, ditches, swales and retention/detention ponds. These data will be
used by the County to generate and maintain a common database that will support water quality, hydrologic and
hydraulic models. This database will also be compatible with the District's GIS database standards.
Benefits
Drainage infrastructure is a critical component in the calibration and verification of hydrologic and hydraulic models.
When fully calibrated, these models generate accurate stage-area relationships, allowing County staff to generate
precise floodplain maps needed to estimate flood risks. When paired with topographic data, Sarasota County will be
able to move ahead with Federal Emergency Management Agency Map Modernization efforts. The improved database
will allow the County to initiate proactive flood protection measures that include the rapid assessment and identification
of potential flooding hot spots, and development of complex what-if scenarios. The database will also support water
quality management efforts and to ensure fishable and swimable waters. County staff will be better equipped to identify
and model key water monitoring locations within coastal watersheds.
Costs
Costs for FY2009 include $100,000 from the Manasota Basin Board and $150,000 from Sarasota County. The cost of
the project through FY2008 is $306,742. The Manasota Basin Board is contributing $100,000 and Sarasota County is
$206,742.
Additional Information
As part of the hydrologic model and for the purposes of this project, horizontal survey data collection refers to
structures such as pump stations, weirs, ponds and wetlands which combine to form part of a drainage infrastructure.
By collecting this information through the means of a horizontal survey the data can be used for more accurate
modeling in the event of severe weather impacts or for planning purposes due to urbanization.
