Stormwater Utility Fee Credit Manual and Homestead Exemptions
Charleston
Summary
The city's stormwater manual requires big projects to design for sea level rise, cut runoff 20% in flood-prone special protection areas, and hit even tougher standards in Church Creek — including 100-year storm storage and 1.25-to-1 mitigation for filling wetlands. Committee members pressed on how often developers use the green infrastructure incentives (not often yet) and whether rules keep pace with county standards.

Impact analysis
The rules can add stormwater costs for developers, though green infrastructure and basin-wide improvements can sometimes save them money.
Residents in flood-prone neighborhoods, especially Church Creek, whose new development now must actively reduce runoff rather than just match it.
Developers face added costs and space constraints, especially downtown where LID practices are harder to fit.
