The Hamilton County Storm Water District is Ohio’s largest NPDES Phase II permittee and is responsible for maintaining permit compliance for its 42 member jurisdictions. One best management practice HCSWD committed to implementing was riparian corridors along streams. An ordinance was passed implementing these corridors along streams that drain 100 acres or greater. The use of spatial data played a significant role in helping public officials determine whether or not to support this ordinance as well as helping to craft the specific elements of this ordinance. Spatial data helped by allowing public officials to visualize several different scenarios to a) determine the upstream extent of the streams protected by the ordinance; b) determine the width of the riparians; and c) visualize the impact this newly protected land might have on future development opportunities.
