(a) The purpose of Sections 146 through 146.11 of Article 4.2 and the City's construction site runoff control program is to protect water quality by controlling the discharge of sediment or other pollutants from construction sites and preventing erosion and sedimentation due to construction activities.
(b) Construction sites can be significant sources of pollution. Materials from construction sites such as concrete, mortars, disturbed soil, sawdust, paint chips, and other debris can be easily transported off construction sites by runoff and wind, and eventually may be washed into storm drains during street cleaning and rainy weather. These sediments can damage infrastructure as well as cause many water quality concerns.
(c) Construction sediment and debris can create local flood hazards by clogging the storm drains and sewer system and reduce the flow capacity, allowing wastewater to spill onto the streets. These sediments are abrasive, and can degrade the pump stations in the sewer system, causing increased maintenance costs, as well as carry toxic pollutants to the bay, local lakes, and the ocean. Also, construction runoff and debris can reduce the capacity and treatment efficiency of the City's collection and wastewater treatment facilities operating during wet weather.
(d) Sections 146-146.11 of Article 4.2 set forth uniform requirements and prohibitions for dischargers and places of discharge to the City's Sewerage System necessary to provide for the protection of water quality and the City's Sewerage System. By implementing these controls, the City is protecting and promoting the public health, safety, and general welfare of its residents, businesses, and visitors.

(a) A Land-disturbing Activity shall be considered in violation of Sections 146-146.11 of Article 4.2
if eroded sediment has been deposited onto adjacent properties, a public right-of-way, a publicly controlled wetland, or the Sewerage System.
(b) The design, testing, installation, and maintenance of erosion and sediment control operations and facilities shall adhere to the standards and specifications contained in the Construction Site Runoff Regulations.
(a) Any person proposing to undertake Land-disturbing Activities shall apply for a Construction Site Runoff Control Permit prior to commencing a Construction Project.
