Project Lower Penitencia Creek Improvements Project
Review Period Thursday, May 18, 2017 to Monday, July 3, 2017
Documents
Description

The Santa Clara Valley Water District (District) proposes to construct and operate improvements to Lower Penitencia Creek from the Coyote Creek confluence to just upstream of the San Andreas Drive bridge located in the City of Milpiltas, CA. The proposed improvements would convey the future increased 1% flows from Berryessa Creek, which discharges to Lower Penitencia Creek at the upstream project terminus without overtopping of Lower Penitencia Creek banks. Berryessa creek is being enlarged by the Lower Berryessa Creek Flood Protection Project under construction by the District and the Upper Berryessa Creek Flood Risk Management Project, under construction by the U.S. Corps of Engineers. The proposed project would extend1% flood protection downstream to the Coyote Creek/Lower Penitencia Creek confluence. The proposed project would meet the following specific objectives:

  • Convey the Lower Berryessa Creek 1-percent design flow; 
  • Meet required water surface elevations at the confluences of Lower Penitencia Creek with Coyote Creek and Berryessa Creek; 
  • Minimize the need for seasonal removal of sediment and non-woody vegetation; 
  • Maintain existing Federal Emergency Management Agency (FEMA) accreditation of the east levee located between California Circle and Berryessa Creek; and 
  • Ensure the project improvements meet FEMA certification requirements.

Pursuant to the California Environmental Quality Act, the District, as the lead agency for the Project, has prepared a Draft Environmental Impact Report (DEIR) to evaluate environmental impacts of the Project.

PUBLIC REVIEW: The DEIR and all related documents can be reviewed on any District business day between the hours of 7:30 a.m. and 5 p.m., Monday through Friday, at the District’s headquarters building, located at 5750 Almaden Expressway, San Jose, CA 95118. A copy of the DEIR will also be available at the Milpitas Library (160 North Main Street, Milpitas, CA 95035) and at the Milpitas City Hall (455 East Calaveras Boulevard, Milpitas, CA 95035).

The public comment period on the Draft EIR begins on Thursday, May 18, 2017 and closes at 5 p.m. on Monday, July 3, 2017.

PUBLIC MEETING: In conjunction with the public review, the Water District will also conduct a public meeting to discuss the Project and the DEIR on Monday, May 22, 2017 at 6:30 p.m., at the Joseph Weller Elementary School, located at 345 Boulder Street in Milpitas (Multi-purpose room).

Comments on the Draft EIR should be submitted via mail or electronically, by 5 p.m. on Monday, July 3, 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:
