Sarasota County Low-Impact Development Manual

Jones Edmunds developed a Low-Impact Development (LID) Manual for Sarasota County. This LID Manual was based partly on successful design ideas from similar manuals around the country and was tailored to the conditions encountered in Sarasota County. The LID Manual includes information on how to evaluate sites for LID practices, as well as details on four LID practices:

• Detention with biofiltration
• Pervious pavements
• Stormwater reuse
• Greenroof stormwater treatment systems

This project benefits the County in several ways:

• It helps to streamline the permitting of stormwater projects by providing clearly documented standards and protocols
• It helps the County save significantly, both in time and money invested on the stormwater management of roadway projects
• It helps promote sustainable stormwater practices that are environmentally-conscious and sound

While developing the LID Manual, Jones Edmunds incorporated input from a large, involved working group that included various groups within Sarasota County (public and private), SWFWMD, and some nearby communities.

St. Johns County San Sebastian Study

Jones Edmunds assisted St. Johns County with evaluating and developing a coastal resiliency vulnerability assessment for infrastructure and structures within the San Sebastian drainage basin. The assessment assisted the County in both assessing risk and in developing drainage improvements. The project consisted of four primary tasks. The first task identified potential future flooding risks based on the following inputs: 2017 NOAA sea level rise (SLR) projections to characterize coastal flooding risks. Regional stormwater models (West Augustine and/or North Augustine Regional Models) previously developed for the County by Jones Edmunds. We updated the models to characterize potential future inland flooding risks. Our updates reflected changes in boundary conditions and soil storage due to SLR. Using a regional ADCIRC Model to characterize surge levels and wind speeds occurring at typical planning frequencies (i.e., the 25-, 50-, 100-, and 500-year storms). The second task used the results from the first task to identify impacted infrastructure and structures. The third task identified adaptation strategies for five priority infrastructure projects. The strategies included options and conceptual approaches for adaptation along with a time horizon for implementation. The final task provided guidance for future infrastructure planning in areas of increased SLR risk.
