Sarasota County allocated $446,855 to fund the Siesta Key Drainage Improvements Study. The Sarasota County Board of Commissioners officially awarded this contract to engineering consultant WSP USA, Inc. to address chronic vulnerabilities exposed by devastating recent storm seasons, particularly the catastrophic flooding caused by multiple hurricanes. [1, 2, 3, 4]
The primary objectives driving this infrastructure investment include:
📊 Advanced Drainage Modeling & System Review
The urban landscape of the Key is almost entirely built up with residences, high-density condos, and hotels, sitting on flat land that ranges from just below sea level to only 30 feet high. The consultant is tasked with auditing existing infrastructure—including historic permits, as-built construction plans, historical flood complaints, and current stormwater inventories—to create a modern watershed management plan
🚗 Protecting Critical Evacuation Routes
Severe weather has continuously disrupted transit and compromised public safety on the barrier island. The study specifically targets major bottlenecks and state-maintained roadways to figure out how to keep vital transit links clear during natural disasters. [1, 2, 3]
📍 Developing Fixes for Specific “Areas of Concern”
Instead of a broad, generic overview, the $446k contract explicitly requires WSP USA to analyze and develop preliminary engineering designs for up to 15 distinct, high-risk flooding zones. The initial core focus areas include
- Midnight Pass Road (specifically the 6600 and 8100 blocks)
- The Midnight Pass Road–Higel Avenue–Siesta Drive Evacuation Corridor
- Ocean Boulevard / Banan Place / Higel Avenue intersections
- Island Circle and the Grand Canal neighborhood
- The Sabal Lake Area (including Old Stickney Point Road, Sabal Drive, and Peacock Road)
- 1122 Horizon View Drive
🏗️ Preparing for Multi-Million Dollar Capital Projects
Sarasota County cannot fix these multi-million dollar stormwater infrastructure failures blindly. The ultimate purpose of spending $446,000 now is to deliver actionable, data-driven engineering recommendations. By establishing these exact preliminary designs and “levels of service” data, the county will have the necessary blueprints to construct new physical flood barriers, retrofit pump stations, and successfully apply for highly competitive federal and state mitigation grants.
The full initiative kicked off in late 2026, and the finalized study with engineering recommendations is expected to be delivered by late August 2027
