Present Land Use
The City of Escondido General Plan classifies the project site and surrounding areas as General Industrial Land Use with an underlying zoning designation of General Industrial (M-2). The site is currently developed with one single wide trailer used by the City's recycling group, one quadruple wide trailer previously used for training by various City departments, a metal storage building and an asphalt paved parking lot. The remainder of the site is used by the City Public Works and Utilities Departments for storage and heavy equipment training, except for a location on the west side that is used by EDCO, a waste disposal corporation, for the storage of empty roll-off bins. An asphalt construction company and waste disposal site are located to the north of the project site; Escondido City Public Works Yard and a mix concrete supplier to the east; Sprinter maintenance yard, heavy industrial and a variety of commercial retailers to the south; and industrial uses and a mix of commercial retailers and Interstate 15 to the west. The project site is accessible via a driveway along West Washington Avenue and a shared access driveway with two gated entrances on the west side. The site also is accessible towards the southeastern corner of the property from a bridge across the concrete flood control channel that connects the site to the City's Public Works Yard.
Document Description
The City currently produces tertiary-treated recycled water (recycled water), which is used for landscape and industrial purposes. Recycled water provided by the City is produced at the Hale Avenue Resources Recovery Facility (HARRF), a recycled water treatment and disposal facility that is owned and operated by the City. The HAR RF provides recycled water to other agencies as well as the City and excess recycled water that is not used by the City or sold to other recycled water customers, is disposed of via an ocean outfall. The City has in the past several years expanded the recycled water conveyance system towards the eastern areas of the City (recycled water pipelines, brine disposal pipeline and fiber optic conduits, recycled wate'r pump station and recycled water storage tank). The City expanded its recycled water system to result in a more dependable and sustainable water supply and to be less dependent on imported water for the City. The Escondido MFRO Facility would provide advanced treatment for Title 22 quality reuse water produced at the HARRF. The facility would utilize membrane filtration (MF) (i.e., microfiltration or ultrafiltration membranes) and reverse osmosis (RO) technologies sized for a total production capacity of 2.0 million gallons per day (mgd). High quality treated water would be blended with Title 22 recycled water within an on-site blend tank. The water would then be sent through the existing non-potable reuse water/agriculture pipelines and distributed to growers. This project component was originally conceptualized as part of the City's Potable Water Reuse Program (Reuse Program) identified in the Recycled Water Master Plan. See NOC for full project description.
