SC H4050

Defines "concurrency programs" as a zoning technique allowing local governments to condition approval of land development on adequate public facilities and services being available to support that development

Requires concurrency programs to use reasonable, locally documented level of service standards and proportionate share methodologies to ensure infrastructure adequacy

Authorizes local governments to require developers to contribute their proportionate share of costs to offset impacts on public facilities and services

Mandates that any contributions already made through development impact fees be credited against concurrency requirements to avoid double charging

Allows local governments and property owners to enter into written agreements for proportionate share, cost sharing, or similar arrangements to implement concurrency requirements
