As used in this chapter, the following terms are defined in this section:
"Accelerated erosion"means the rate and amount of erosion caused by development activities that exceed the natural processes by which the surface of the land is worn away. Erosion includes the movement or loss of soil by the action of water, wind or chemicals.
"Authorized water quality enforcement staff"means any person designated or assigned by the city manager to undertake inspector duties including, but not limited to, inspection, investigation and enforcement of any provisions of this chapter.
"Best management practices (BMPs)"means any program, activity, technology, process, siting criteria, operational method, practice, facility and/or procedure that when properly implemented will control, prevent, remove or reduce pollutants in discharges. "Source control" BMPs (both structural and nonstructural) are operational practices or methods that prevent pollution by reducing potential pollutants at the source. A "site design" BMP is a source control BMP and means any design feature that reduces the creation or severity of potential pollutant sources or reduces the alteration of the project site's natural flow regime. "Treatment control" BMPs are structural methods of treatment to remove pollutants from urban runoff. (The city utilizes the BMPs which have been specified in the city's jurisdictional urban runoff management program/local implementation plan (JURMP/LIP). Presently, these BMPs have been developed, and may be amended from time to time, by the California Stormwater Quality Association (CASQA) and can be referenced at
www.cabmhandbooks.com. The city reserves the right to implement any equivalent BMP prepared by other qualified water quality organizations or government agencies.)
"City"means the city of Laguna Beach, Orange County, California.
"Clean Water Act Section 303(d) water body"is an impaired water body in which water quality does not meet acceptable water quality standards and/or is not expected to meet water quality standards, even after the application of technology based pollution controls required by the Clean Water Act. The discharge of urban runoff to these water bodies by the co-permittees is significant because these discharges can cause or contribute to violations of applicable water quality standards.
"Coastal development permit"means a permit issued under the authority of Chapter
25.07 and the California Coastal Act by the city of Laguna Beach or the coastal commission to perform or undertake any development, as that term is defined in Section 25.07.066(D), within the city's coastal zone.

If any discharges that fall within this exception are subject to State or Regional Water Quality Control Board permits or local ordinances, they are exempt only if the discharger is in compliance with said permits or local ordinances,
(L) Potable water sources, except to the extent such discharges are subject to, but not in compliance with general permits issued by the State or Regional Water Quality Control Board or other local ordinances,
(M) Individual residential car washing; except to the extent that pollutants are discharged to the MS4,
(N) Dechlorinated swimming pools,
(O) Emergency firefighting activities;
* These discharges may be covered by a State or Regional Water Quality Control Board permit for groundwater extraction or similar discharges to surface waters. The city authorized these discharges in compliance with such permit, unless the city staff determines the discharge potentially causes, or threatens to cause a condition of pollution, contamination or nuisance. |

"Redevelopment"means the proposed creation, addition, and/or replacement of impervious surface area on an already developed site. Examples include the expansion of a building footprint, road widening, the addition to or replacement of a structure, and creation or addition of impervious surface areas. Replacement of impervious surface areas includes any activity that is not part of a routine maintenance activity where impervious material(s) are removed, exposing underlying soil during construction. Redevelopment does not include trenching and resurfacing associated with utility work, resurfacing existing roads; and routine replacement of damaged pavement, such as pothole repair.
"State general permit"means either the state general industrial storm water permit or the state general construction permit and the terms and requirements of either or both. In the event the U.S. Environmental Protection Agency revokes the in-lieu permitting authority of the State Water Resources Control Board, then the term state general permit shall also refer to any EPA administered storm water control program for industrial and construction activities.
"Storm water"means that portion of precipitation that flows across a surface to the storm water drainage system or receiving waters. Examples of this phenomenon include, but are not limited to: the water that flows off a building's roof when it rains (runoff from an impervious surface); the water that flows from a vegetated surface when rainfall is in excess of the rate at which it can infiltrate into the soil (runoff from a pervious surface); and the water that flows into streams when snow on the ground begins to melt (runoff from a semi-impervious surface). Runoff generally increases as the perviousness of a surface decreases. During precipitation events in urban areas, rain water picks up and transports pollutants through storm water conveyance systems and ultimately to water of the United States.
"Storm water drainage system"means any street gutter, channel, storm drain, constructed drain, lined diversion structure, wash area, inlet, outlet or other facility which is a part of or tributary to the city-wide storm water runoff system and used for the purpose of collecting, storing, transporting or disposing of storm water. (Refer to municipal separate storm sewer system.)
"Urban runoff"means all flows in a storm water drainage system and consists of the following components:
(1) Storm water (wet weather flows); and
(2) Non-storm water discharges (dry weather flows).
Storm water and non-storm water flows may consist of both prohibited and non-prohibited discharges as defined in the NPDES/MS4 permit and this code. |
"Water quality/urban runoff management plan (WQMP)"means a water quality plan which identifies and details appropriate/necessary source control, site design, and structural treatment BMPs that are incorporated into the project design to prevent, reduce or remove, to the maximum extent practicable, pollutant discharges, accelerated erosion and sediment runoff during development construction and operation activities. Synonymous terms for such a water quality plan are standard storm water mitigation plan (SSMP) and standard urban storm water mitigation plan (SUSMP).
