The project corridor is located within the jurisdictional boundary of the South Florida Water Management District (SFWMD) and include the following SFWMD drainage basins: C-10, Dania Cut-off Canal and South Fork New River Basins. The regulations of SFWMD govern the minimum stormwater management design criteria for the project; however, the proposed stormwater management system also conforms to any additional design requirements of the Florida Department of Environmental Protection (FDEP) and United States Army Corps of Engineers (USACE), as well as the Florida Department of Transportation (FDOT), District 4.
BCC’s Water Resource Group was responsible for designing three drainage segments: Segments 1B, 2A and 2B. The drainage improvements include new dry detention/retention swales, modification to existing dry and wet detention ponds, re-gradating interchange infield ponds and the installation of the new control structures, new outfalls connections and construction of five new Jack & Bore culverts under I-95 connecting west and east swales or ponds.
Software used during drainage design:
- Advanced Integrated Channel and Pond Routing (AdICPR) v3- for water quantity (peak discharge rate into all receive body waters pre. vs post-conditions and peak stages)
- Automated Storm Sewer Analysis ASAD v3- for storm drain system analysis.
- HY8 for analyzing culvert cross drains
- Culvert Service Life Estimated (CSLE)- for Optional Pipe Material calculations.
As part of this project BCC obtained a construction Environment Resources Permit (ERP) from the SFWMD and a USACE 404 Permit for impacts to other surface water.
