"Best management practice (BMP)"means structural device, measures, facility, activity, schedules of activities, prohibitions of practices, general good housekeeping practices, pollution-prevention practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants directly or indirectly to waters of the United States. BMPs also include treatment requirements, operating procedures, and practices to control plant-site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
"Biotreatment soil media (BSM)"means a soil blend designed to meet the specifications approved by the San Francisco Bay Regional Water Quality Control Board Executive Officer and incorporated into the C.3 Technical Guidance Manual.
"C.3 Technical Guidance Manual"means the most recent version of the Alameda Countywide Clean Water Program manual that sets forth guidance, design standards and best management practices for low impact development.
"City"means the city of Pleasanton.
"Construction activity"means any activity that involves soil disturbing activities including, but not limited to, grubbing, clearing, filling, leveling, building, paving, grading, demolition, and ground disturbances such as stockpiling and excavation unless exempted by the municipal code.
"Development runoff requirements"means the provisions in the MRP and any additional city of Pleasanton standards that contain performance standards to address both the construction and post-construction phase of new development and redevelopment projects.
"Development" or "development project"means construction, rehabilitation, redevelopment, or reconstruction of any public or private residential project (whether single-family, multi-unit, or planned unit development); or industrial, commercial, retail or other nonresidential project, including public agency projects. Development project as defined here and used in this chapter includes redevelopment, which means land-disturbing activity that results in the creation, addition, or replacement of exterior impervious surface area on a site on which some past development has occurred.
"Director"means the public works director of the city of Pleasanton, or his or her designee.
"Discharge"means: (a) any addition or discharge of any pollutant, waste, or combination of pollutants and waste directly or indirectly to the storm drain system or to waters of the United States or waters of the state from any activity or operation; or (b) any addition of any pollutant, waste, or combination of pollutants and waste directly or indirectly to the storm drain system or to the waters of the contiguous zone or the ocean from any activity or operation other than a vessel or other floating craft being used as a means of transportation.
This includes additions of pollutants or waste to waters of the United States or waters of the state from: surface runoff which is anthropogenically collected or channeled; discharges through pipes, sewers, or other conveyances, including street surfaces and curb and gutters, owned by a state, municipality, or other person which do not lead to a treatment facility; and discharges through pipes, sewers, or other conveyances, leading to privately owned treatment works. |
"Discharger"means a person or entity who or which, respectively, allows, causes, permits to occur, or performs a discharge. "Discharger" also means the owners of real property on which such activities, operations or facilities are located; provided, however, that a local government or public authority is not a discharger as to activities conducted by others in public rights-of-way.
"Front yard"means an open space extending the full width of the lot, between a building and the front lot line, unoccupied and unobstructed from the ground upward, except as specified elsewhere in this title.
"Full trash capture" or "full trash capture system or device"means any device or series of devices that traps all particles retained by a minimum five-millimeter mesh screen and has a design treatment capacity of not less than the peak flow rate resulting from a one-year, one-hour storm in the tributary drainage catchment area.

"Green stormwater infrastructure (GSI)"means infrastructure that uses vegetation, soils, and natural processes to manage water and create healthier urban environments. At the scale of a city or county, green infrastructure refers to the patchwork of natural areas that provides habitat, flood protection, cleaner air, and cleaner water. At the scale of a neighborhood or site, green infrastructure refers to stormwater management systems that mimic nature by soaking up and storing water. As low impact development (LID) practices are often implemented with GSI, these concepts are together referred to as LID/GSI.
"Hydromodification"means modification of a stream's hydrograph, caused in general by increases in flows and durations that result when land is developed (e.g., made more impervious). The effects of the hydromodification include, but are not limited to, increased bed and bank erosion, loss of habitat, increased sediment transportation and deposition, and increased flooding.
"Hydromodification management (HM)"means engineered systems designed to minimize changes to the hydrograph (hydromodification) resulting from development by matching the flow durations (long-term temporal patterns of volume and rate) of the pre-project runoff.
"Illicit connection"means any device or method that conveys an illicit discharge to an MS4 or receiving water or any conveyance that has not been documented in plans, maps, or equivalent records and approved by the city of Pleasanton.
"Illicit discharge"means any discharge to the MS4 that is prohibited under local, state, or federal statutes, ordinances, codes, or regulations. This includes all non-stormwater discharges not composed entirely of stormwater, except discharges allowed pursuant to an NPDES permit (other than the NPDES permit for discharges from the MS4).
"Industrial activity"means any activity that involves manufacturing, processing, or raw materials storage areas. Further definition of activities covered is provided in 40 Code of Federal Regulations Section
122.26(b) and the Statewide Industrial General Permit.
"Landscaping"means the planting and maintenance of trees, shrubs, lawns and other evergreen ground cover or material, including inorganic accessory materials utilized to accent or complement the vegetation.
"Lot"means a piece or parcel of land owned as a single unit in common ownership, occupied or intended to be occupied by a principal building or a group of such buildings and accessory buildings, or utilized for a principal use and uses accessory thereto, together with such open spaces as are required by this title, and having frontage on and access to an approved and accepted city of Pleasanton street that meets the standards of width and improvements as specified in the regulations of the city of Pleasanton contained in or adopted pursuant to the subdivision title and street improvement chapter as to the section and the frontage of the lot involved, or having frontage on and access to an approved private street.
"Low impact development (LID)"uses site design and stormwater management to maintain the site's pre-development runoff rates and volumes. The goal of LID is to mimic a site's predevelopment hydrology by using design techniques that infiltrate, filter, store, evaporate, detain, and/or biotreat stormwater runoff on or near the site. At the site scale, GSI is a subset of LID. As LID practices are often implemented with GSI, these concepts are referred together as LID/GSI.
"Maximum extent practicable (MEP)"means a standard for implementation of stormwater management programs to reduce pollutants in stormwater to the maximum extent possible, taking into account equitable considerations and competing facts, including, but not limited to, the seriousness of the problem, public health risks, environmental benefits, pollutant removal effectiveness, regulatory compliance, cost and technical feasibility.
"Municipal regional stormwater NPDES permit (MRP)"means the California Regional Water Quality Control Board San Francisco Bay Region Municipal Regional Stormwater NPDES permit issued to the city of Pleasanton, NPDES Permit No. CAS612008 and any subsequent amendment, reissuance, or successor to this NPDES permit.
"Municipal separate storm sewer system (MS4)"means and includes, but is not limited to, those facilities within the city of Pleasanton by which stormwater may be conveyed to waters of the United States, including any roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains, which are not part of a publicly owned treatment works (POTW) as defined at 40 Code of Federal Regulations Section
122.2.
"NPDES"means National Pollutant Discharge Elimination System.

"Pollutant"means dredged soil, solid waste, incinerator residue, filter backwash, sewage, pet wastes, manure, garbage, sewage sludge, munitions, chemical wastes or byproducts, fuels, biological materials, radioactive materials (except those regulated under the Atomic Energy Act of 1954, as amended (42 U.S.C.
2011 et seq.)), heat, wrecked or discarded equipment, sediment, contaminated waste discharged from hot tubs, pools or spas, dumped yard wastes, food related wastes, rock, sand, dirt, and industrial, municipal and agricultural waste discharged into water, or placed in an area or manner such that it could be swept away or carried by stormwater runoff.
"Premises"means any building, lot, parcel, real estate, or land or portion of land, whether improved or unimproved, including adjacent sidewalks and parking strips.
"Regulated project"means a development project, as defined in MRP Provision C.3.
