Funding for the Stormwater Management Program comes primarily from the Stormwater Utility. The Utility is based on equitable cost-sharing measures which allocate responsibility to users of the stormwater management system. The property's contribution to runoff is defined by impervious coverage per developed tract of land. Both commercial and non-commercial developments are charged a fee and includes for-profit and not-for-profit property owners.
