Editor's Notes: The bracketed division headers in this Article have been provided by the editor for the convenience of the user and are not official parts of this Code. Ordinance 83-10 repealed former Secs. 140-149.4 and enacted new material currently codified as Secs. 147-147.6. [Construction Site Runoff] SEC. 146. CONSTRUCTION SITE RUNOFF CONTROL. (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) The intent of Sections 147-147.6 of this Code is to reduce the volume of stormwater entering the City's Combined and Separate Sewer Systems and to protect and enhance the water quality of receiving waters, pursuant to, and consistent with Federal and State laws, lawful standards and orders applicable to stormwater and urban runoff control, and the City's authority to manage and operate its drainage systems. (b) Urban runoff is a significant cause of pollution throughout California. Pollutants of concern found in urban runoff include sediments, non-sediment solids, nutrients, pathogens, bacteria, oxygen-demanding substances, petroleum hydrocarbons, heavy metals, floatables, polycyclic aromatic hydrocarbons (PAHs), trash, and pesticides and herbicides. (c) During urban development, two important changes occur. First, where no urban development has previously occurred, natural vegetated pervious ground cover is converted to impervious surfaces such as paved highways, streets, rooftops, and parking lots. Natural vegetated soil can both absorb rainwater and remove pollutants, providing a very effective purification process. Because pavement and concrete can neither absorb water nor remove pollutants, the natural retention and purification characteristics of the land are lost, increasing the volume of stormwater entering the collection system and the concentration of pollutants within that water. Second, urban development creates new pollutant sources, including vehicle emissions, vehicle maintenance wastes, pesticides, household hazardous wastes, pet wastes, trash, and other contaminants that can be washed into the City's Separate or Combined Sewer Systems. (d) A high percentage of impervious area correlates to a higher rate of stormwater runoff, which generates greater pollutant loadings to the City's Separate and Combined Sewer Systems, resulting in turbid water, nutrient enrichment, bacterial contamination, toxic compounds, temperature increases, and increases of trash or debris. (e) When stormwater impacts are considered during the planning stages of a project, new development and redevelopment projects can more efficiently incorporate Post-Construction Stormwater Controls that will enhance the function and capacity of the City's Separate and Combined Sewer Systems by providing pretreatment of stormwater and protecting water quality. (f) Sections 147-147.6 of this Code protect the health, safety and general welfare of the City's residents by: (1) reducing stormwater runoff rates and volume whenever possible through Post-Construction Stormwater Controls, and ensuring that these stormwater controls are safe and properly maintained; (2) minimizing increases in pollution caused by stormwater runoff from development that would otherwise degrade local water

quality; and (3) controlling the discharge of contaminants to the City's sewer and drainage systems through spills, dumping, or disposal. (Added by Ord. 83-10, File No. 100102, 4/22/2010; amended by Ord. 64-16 , File No. 160155, App. 4/27/2016, Eff. 5/27/2016)

Large Development Project. Any construction activity that will result in the creation and/or replacement of 5,000 square feet or more of impervious surface, measured cumulatively, that is located on a property that discharges or will discharge Stormwater to the City's Separate or Combined Sewer System. Activities that create or replace impervious surface include, but are not limited to, the construction, modification, conversion, or alteration of any building or structure and the creation or replacement of outdoor impervious surfaces such as parking areas, driveways, private street areas, or new public rights-of way to be dedicated to and accepted by the City within Large Development Projects that are subject to the Subdivision Code. Activities that create or replace impervious surface do not include interior remodeling projects, replacement of existing sidewalks and streets dedicated to and accepted by the City, routine maintenance or repair activities such as pavement resurfacing within the existing footprint, exterior wall surface replacement, and re-roofing. In areas that connect to the Separate Sewer System, Large Development Projects also include discrete linear utility and road projects that result in 5,000 square feet or more of newly constructed contiguous impervious surface including, but not limited to, the construction of new streets or the widening of existing streets with additional traffic lanes. Non-Stormwater Discharge. Any discharge to the City's Separate or Combined Systems that is not composed entirely of Stormwater. Pollutant.

Separate Sewer System. Facilities under the jurisdiction of the Department that collect, convey and discharge Stormwater, without combining Stormwater and sewage in the same facilities. Small Development Project. Any development activity that will result in the creation or replacement of between 2,500 and 5,000 square feet of impervious surface, measured cumulatively, which is located on a property that is connected or proposing to connect to the Separate Sewer System. Activities that create or replace impervious surface include, but are not limited to, the construction, modification, conversion, or alteration of any building or structure and the creation or replacement of outdoor impervious surfaces such as parking areas, driveways, private street areas, or new public rights-of-way to be dedicated to and accepted by the City within Small Development Projects that are subject to the Subdivision Code. Activities that create or replace impervious surface do not include: interior remodeling projects; replacement of existing sidewalks and streets dedicated to and accepted by the City; routine maintenance or repair activities, such as pavement resurfacing within the existing footprint, exterior wall surface replacement, and re-roofing. Stormwater. Runoff that is generated when precipitation from rain events flows over land or impervious surfaces and does not percolate into the ground. Stormwater Control Plan.
