Learn MoreDrainage Challenges in Orange County
Orange County straddles two Water Management Districts — SFWMD and SJRWMD — meaning projects may need to comply with entirely different design standards depending on exact location within the county. Chapter 37's stormwater code governs local requirements, while SJRWMD's 40C-42 criteria impose a 72-hour drawdown standard. The rapid growth of the Central Florida corridor creates constant demand for drainage engineering.
Dual WMD jurisdiction
Orange County is split between SFWMD and SJRWMD — projects may need to comply with different design standards depending on exact location. CivilSmart understands both sets of requirements.
Orlando Non-Compliance List
The City of Orlando maintains and enforces a Non-Compliance List for Private Storm Systems — property owners on this list face enforcement action and need engineering services.
Central Florida Water Initiative (CFWI)
Shared jurisdiction under SJRWMD creates additional water resource management requirements beyond standard ERP permitting.
Rapid growth area
Central Florida's construction boom creates constant demand for drainage engineering, with master grading/drainage plans required for all subdivisions.
