CITY COUNCIL REGULAR MEETING AGENDA PACKET

"Discharge" means: (a) any addition of any pollutant to navigable waters from any point source; or (b) any addition of any pollutant to the waters of the contiguous zone or the ocean from any point source other than a vessel or other floating craft. 12. “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. 13. “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. 14. “Full trash capture” or a “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. 15. “GPS Coordinates” means a set of unique identifiers of a precise geographic location on the earth, usually expressed in alphanumeric characters as the location’s latitude and longitude values. 16. “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. 17. “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. 18. “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. 19. “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. 20. “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). "Illicit discharge" means any discharge to the city storm sewer system that is not composed entirely of stormwater except discharges pursuant to a NPDES permit and discharges resulting from firefighting activities. 21. “Industrial Activity” means any activity that involves manufacturing, processing, or raw materials Page 283 of 428
