Project Pacheco Reservoir Expansion Project Initial Study and Notice of Preparation
Review Period Friday Aug. 11, 2017 to Monday, Sept. 11, 2017
Documents
Description

This Initial Study and Notice of Preparation (NOP) has been prepared by the Santa Clara Valley
Water District (SCVWD) as part of the Pacheco Reservoir Expansion Project (Project) to
evaluate the potential physical, biological and cultural impacts of expanding the existing
Pacheco Reservoir. The Project is being conducted consistent with the California Environmental
Quality Act (CEQA), and other pertinent federal, state, and local laws and policies. SCVWD is
serving as the lead agency for compliance with CEQA.

The project includes construction and operation of a new dam and reservoir, pump station, conveyance facilities, and related miscellaneous infrastructure (e.g., access roads). The new dam and reservoir would be constructed on Pacheco Creek 0.5 mile upstream from the existing North Fork Dam, and would inundate most of the existing Pacheco Reservoir. The proposed total storage for the new reservoir is 141.6 TAF, with an active storage of 140.8 TAF. Water will be collected in the new reservoir during the winter months from runoff from the local watershed area, and diversion of CVP supplies from Pacheco Pipeline, when needed.

Comments on the NOP should be submitted via mail or electronically, by 5 p.m. on Monday, Sept. 11, 2017, to:

Project Cunningham Flood Detention Facility Certification Project
Review Period Thursday, July 20, 2017 to Monday, August 21, 2017
Documents
Description

The proposed Cunningham Flood Detention Facility Certification Project (Project) would construct improvements within Lake Cunningham Park (LCP) to ensure the flood detention capability of LCP, reduce flow hazards to urbanized areas along Lower Silver Creek downstream of LCP, and meet Federal Emergency Management Agency (FEMA) safety requirements for flood protection levees and floodwalls. The proposed Project would consist of increasing the crest elevation of an existing earthen levee along the banks of Lower Silver Creek, constructing a new concrete floodwall along Lower Silver and Flint Creeks, constructing a new pedestrian pathway, relocating an existing trash compactor and green waste collection area, regrading a 70-foot portion of trails along the Lake Cunningham shoreline, and in-kind replacement of the existing chain-link fencing.

The Draft MND will be available for public review from 8 a.m. to 5 p.m. weekdays at the Santa Clara Valley Water District Headquarters Building (5700 Almaden Expressway, San Jose, CA 95118) for 30-days starting July 20, 2017. A copy of the Draft MND will also be available at the Hillview Branch Library reference desk at 1600 Hopkins Drive in San Jose, CA 95122 and the Evergreen Branch Library reference desk at 2635 Aborn Road, San Jose, CA 95121.

Comments on the Draft MND should be submitted via mail or electronically, by 5 p.m. on August 21, 2017, to:

Project Main and Madrone Pipeline Restoration Project Initial Study/Mitigated Negative Declaration
 


UPDATED 5/25/2017

Review Period Wednesday, March 1, 2017 to Friday, March 31, 2017
Documents
Description

The proposed project includes the replacement of the Main Avenue and Madrone Pipelines outside the City of Morgan Hill with larger pipelines to restore their full operational capacity and to convey adequate flows to meet future sub-basin groundwater recharge requirements in the Llagas groundwater subbasin. The proposed project would be implemented along three major segments as described below

  • Segment 1 (Main Avenue Pipeline): 2,800 linear feet of 16-inch diameter pipe from the Anderson Reservoir outlet to the Cochrane Road and Half Road intersection will be replaced with 36-inch pipe
  • Segment 2 (Main Avenue Pipeline): 4,860 linear feet of 16-inch, 18-inch, and 24-inch diameter pipe from the Cochrane Road and Half Road intersection to the Main Avenue Percolation Ponds will be replaced with 30-inch pipe.
  • Segment 3 (Madrone Pipeline): 6,300 linear feet of 24-inch diameter and 30-inch diameter pipe from the Cochrane Road and Half Road intersection to the Madrone Channel will be replaced with 30-inch pipe.

In addition, underground utility vaults would be constructed at the end of the pipelines; the existing discharge pipes at the Main Avenue ponds and the Madrone Channel would be upgraded to include an energy dissipater; and an existing chemical feed station on Cochrane Road would be demolished and reconstructed north of Main Avenue near the Main Avenue turnout. The chemical feed station would be approximately 299 square feet. The proposed project would include restoring the roads once construction activities are complete.

The Draft MND will be available for public review from 8 a.m. to 5 p.m. weekdays at the District Headquarters Building (5700 Almaden Expressway, San Jose, CA 95118) starting Wednesday, March 1, 2017 and ending on Friday, March 31, 2017. A copy of the Draft MND will also be available at the Morgan Hill Public Library reference desk at 660 West Main Avenue, Morgan Hill, California 95037.

Comments on the Draft MND should be submitted via mail or electronically, by 5 p.m. on Friday, March 31, 2017, to:
