Title

CP20051 New Reservoir 5B-2

Description

The Cucamonga Valley Water District (CVWD) proposes to construct New Reservoir 5B-2 adjacent to its existing Reservoir 5B, which is a 1 MG welded steel tank constructed in 1975 in the northern area of Rancho Cucamonga. New Reservoir 5B-2 will be a 3 MG welded steel tank approximately 136 feet in diameter and 32 feet high. Improvements also include associated underground piping. This analysis assumes that the Proposed Project would be constructed during 2025 over a period of approximately 15 months. Less than 10 workers would be required during construction. Construction is planned to generally occur within daylight hours and the time period allowed by City Ordinance. The City of Rancho Cucamonga Noise Ordinance allows construction 7 am to 8 pm Monday through Saturday, and for the City of Upland it is 7 am to 6 pm Monday through Saturday. It is anticipated that no nighttime or weekend construction would occur. The Project Site is generally located north of Hillside Road, east of Archibald Ave, west of Haven Ave, and south of the foothills. The Proposed Project would occur on two parcels located within the City of Rancho Cucamonga. Both parcels are currently owned by the CVWD: Assessor’s Parcel Number (APN) 1074-101-22 (currently developed with Reservoir 5B) and APN 1074-101-21 which is vacant and adjacent (on the west side) of the developed parcel. The Project Site is bounded on the north partially by the terminus of Beaver Creek Court and partially by the property boundary of CVWD-owned APN 1074-101-22; on the south by the intersection of Carrari Street and Rocky Mountain Place and by CVWD-owned APN 1074-101-21; on the west by the backyards of residential uses that front Silver Mountain Way and Whispering Forest Drive; and on the east by Mayberry Ave. Both Project parcels are zoned Very Low Residential (VL) according to the City of Rancho Cucamonga General Plan Zoning Map. The general process for construction consists of site earthwork (including grading and excavation), installation of proposed facilities, site restoration, and limited site demolition (removal of existing fencing). Native material will be screened on-site and used for fill. Rejected materials will be left on site. Imported fill material may be required. Earthwork includes the site grading , re-grading of the existing northeastern slope to a flatter slope, and the excavation for the tank, which will be approximately 14 feet deep. Project construction is anticipated to begin in 2025 and last approximately 15 months. Construction would require staging area(s) to store supplies and materials temporarily. It is anticipated that the staging area(s) for construction equipment and materials would be in the southwest portion of the Project Site. Panels of the welded steel tank will be staged on the Project Site and welded in place. Once constructed, no permanent staff would be at the Project Site; however, it is assumed that the new facilities would require monitoring, consisting of one or two vehicles visiting the site on a daily basis. Maintenance activities would be expected to require one to two visits per month. This level of activity would be similar to current conditions for the existing tank.
