3. Design Analysis

Lee Board of County Commissioners · 2026-05-19 · agenda_item

This notice concerns a planned weir reconfiguration project in Lee County. The project involves a preliminary design report to estimate peak flows and recommend changes to the existing weir. This will include reviewing hydrologic and hydraulic models to find flood mitigation options. A sub-consultant will examine the current weir and floodway, then prepare a report on potential designs, including gate types, materials, and water levels. The project will update a FEMA flood model to include existing ground and weir shapes, then create a proposed model with new structures. This comparison will check if the project raises flood levels. If it does, up to two alternatives will be studied to prevent this. The sub-consultant will also prepare a No-Rise Certification package and respond to county staff requests. HighSpans Engineering will handle structural analysis and design for the weir, looking at steel or concrete options for an economical and buildable structure. This early stage of the project presents opportunities for engineering consultants, surveyors, material suppliers, and construction firms specializing in civil and structural work. Engaging now allows businesses to understand the project scope and prepare for future bidding processes before final plans and permits are issued.
