Phelan Piñon Hills Community Services District Well No. 18 Development Project

The District seeks to install a new well at one of the two proposed locations as part of their CIP, which would both aid the District in meeting current and future demand, and minimize Chromium-6 concentrations in the District’s water supply. Well No. 18 is proposed to be located on 2.2-acre parcel (Assessor’s Parcel Number [APN] at APN 3100-561-14) in the northern portion of the District, along Beekley Road, south of Begonia Road and north of Highway 18. A backup location for Well 18 (Backup Well site) is proposed to be located on a 2.2-acre parcel (APN 3101-381-25) in the northern portion of the District, at the northeast corner of Barker Road and Camellia Road, east of Sheep Creek Road and North of Highway 18. This Initial Study analyzes the impacts of installing one well, but analyzes the site constraints associated with developing the well at the Well 18 or Backup Well site. At each of the well locations, pipeline would need to be installed to connect the new water supply to the District’s existing supply system. The Well 18 site would require installation of about 600 lineal feet (LF) of water pipeline from the project site north along Beekley Road to an existing District water distribution pipeline at Begonia Road. The Backup Well site would require installation of about 1,800 lineal feet (LF) of water pipeline from the project site west along Camellia Road to an existing District water distribution pipeline at Sheep Creek Road. The pipeline, at either site, is anticipated to be 12” diameter in size. The site would include the following features: a 4” drain line to the retention basin; a 10’ x 10’ chlorination building adjacent to the proposed well; and, a 4” conduit, switch gear, and transformer to connect to the existing powerline pole.
