Commercial businesses in the City have the potential to contribute a wide variety of pollutants to the stormwater drainage system depending on the type of operation and the specific activities conducted on the site. The City maintains an inventory of commercial businesses and verifies the implementation of designated minimum stormwater best management practices (BMP) (PDF) to ensure that commercial facilities are not causing or contributing to a violation of water quality standards. The City performs annual inspections of commercial facilities, provides education material and education to local businesses, and enforces the Urban Runoff Management and Discharge Control Ordinance 8.30. The City also requires specific stormwater conditions for mobile businesses and special events.
