A state-mandated stormwater requirements meant for construction and development projects has been implemented in CampbellCounty. The Board of Supervisors adopted the ordinance following a public hearing on Tuesday. The ordinance would place the stormwater management plan and corresponding permitting process under county management, as required by the state. Each Virginia locality is required to adopt an ordinance and fee structure by May 15 and assume management of the program July 1. Along with the erosion and sediment laws already in place, the mandate means higher fee structure and more stringent technical criteria for water quality and pollution reduction.
