“Project footprint” means the limits of all grading and ground disturbance, including landscaping, associated with a project. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.200)

16.101.140 Receiving waters.

“Receiving waters” means surface bodies of water that directly or indirectly receive discharges from urban runoff conveyance systems, including naturally occurring wetlands, streams (perennial, intermittent, and ephemeral (exhibiting bed, bank, and ordinary high water mark)), creeks, rivers, reservoirs, lakes, lagoons, estuaries, harbors, bays and the Pacific Ocean. The Director of Development Services shall determine the definition for wetlands and the limits thereof for the purposes of this definition, provided this definition is as protective as the Federal definition utilized by the United States Army Corps of Engineers and the United States Environmental Protection Agency. Constructed wetlands are not considered wetlands under this definition, unless the wetlands were constructed as mitigation for habitat loss. Other constructed BMPs are not considered receiving waters under this definition, unless the BMP was originally constructed in receiving waters. Construction of treatment control BMPs in receiving waters is prohibited and therefore may not be used to satisfy SUSMP requirements. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.210)

“Restaurant” means a facility that sells prepared foods and drinks for consumption, including stationary lunch counters and refreshment stands selling prepared foods and drinks for immediate consumption (Standard Industrial Classification code 5812). Restaurants where the land area for development is greater than 5,000 square feet shall meet all SUSMP requirements. Restaurants where the land development is less than 5,000 square feet shall meet all SUSMP requirements except for the structural treatment BMP and numeric sizing criteria requirement and the hydromodification requirement. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.240)

16.101.180 Significant redevelopment.

“Significant redevelopment” means development that would create, add, or replace at least 5,000 square feet of impervious surfaces on an already developed site that falls under one or more priority development project categories. Significant redevelopment includes, but is not limited to, the expansion of a building footprint; addition to or replacement of a structure; replacement of an impervious surface that is not part of a routine maintenance activity; and land disturbing activities related with structural or impervious surfaces. Replacement of impervious surfaces includes any activity that is not part of a routine maintenance activity where impervious material(s) are removed, exposing underlying soil during construction. Significant redevelopment does not include trenching and resurfacing associated with utility work; resurfacing and reconfiguring surface parking lots; new sidewalk construction, pedestrian ramps, or bike lane on existing roads; and replacement of damaged pavement.

16.101.190 Site design BMP.

“Site design BMP,” also known as a significant part of low impact development (LID), means any project design feature that reduces the amount of impervious surfaces, disconnects impervious surfaces, reduces creation or severity of potential pollutant sources, and/or reduces the alteration of the project site’s natural flow regime. Redevelopment projects that are undertaken to remove pollutant sources (such as existing surface parking lots and other impervious surfaces) or to reduce the need for new roads and other impervious surfaces (as compared to conventional or low-density new development) by incorporating higher densities and/or mixed land uses into the project design, are also considered site design BMPs. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.270)

16.101.200 Source control BMP (both structural and nonstructural).

“Source control BMP (both structural and nonstructural)” means land use or site planning practices or structures that aim to prevent urban runoff pollution by reducing the potential for contamination at the source of pollution. Source control BMPs minimize the contact between pollutants and urban runoff. Examples include roof structures over trash or material storage areas, and berms around fuel dispensing areas. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.280)

16.101.210 Stormwater best management practice (BMP).

“Stormwater best management practice (BMP)” means any schedule of activities, prohibitions of practices, general good housekeeping practices, pollution prevention and educational practices, maintenance procedures, structural treatment BMPs, and other management practices to prevent or reduce to the maximum extent practicable the discharge of pollutants directly or indirectly to receiving waters. It is any procedure or device designed to minimize the quantity of pollutants that enter the storm drain system. Stormwater BMPs also include treatment requirements, operating procedures and practices to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage. This SUSMP groups stormwater BMPs into the following categories: site design, source control, and treatment control (pollutant removal) BMPs. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.290)

16.101.230 Streets, roads, highways, and freeways.

“Streets, roads, highways, and freeways” means any project that is not part of a routine maintenance activity, and would create a new paved surface that is 5,000 square feet or greater used for the transportation of automobiles, trucks, motorcycles and other vehicles. This category includes commercial and residential driveways. For the purposes of SUSMP requirements, streets, roads, highways and freeways do not include trenching and resurfacing associated with utility work; applying asphalt overlay to existing pavement; new sidewalk, pedestrian ramps, or bike lane construction on existing roads; and replacement of damaged pavement. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.310)

16.101.240 Treatment control (structural) BMP.

“Treatment control (structural) BMP” means any engineered system designed and constructed to remove pollutants from urban runoff. Pollutant removal is achieved by simple gravity settling of particulate pollutants, filtration, biological uptake, media adsorption or any other physical, biological, or chemical process. (Ord. 702 § 3, 2010; Ord. 671 § 32, 2008; Ord. 569 § 2, 2002. Formerly 16.101.320)
