ISSUE: Board approval of the Pleasant Hill- Grayson Creek Trunk Sewer, District
Project 8412, is required prior to the filing of a Notice of Exemption under the District's
California Environmental Quality Act (CEQA) Guidelines.
RECOMMENDATION: Approve the Pleasant Hill- Grayson Creek Trunk Sewer, District
Project 8412, for CEQA/permitting purposes.
FINANCIAL IMPACTS: The total project cost is anticipated to be $6,000,000; however,
this position paper only approves the project for CEQA/permitting purposes and does
not award a construction contract.
ALTERNATIVES /CONSIDERATIONS: The Board of Directors may delay or decline to
approve the project. If these renovations are not constructed, the condition of these
sewers will continue to decline and may result in multiple maintenance issues.
BACKGROUND: The Collection System Master Plan 2010 Update analyzed the
District's entire sewer system using an updated ArcSNAP hydraulic model. The wet
weather design flows to the sewers in this project corridor were calculated at 130% to
270% of full pipe capacity. The wet weather capacity- deficient sewers include a 12 -inch
pipe that runs east along Mercury Way from Pleasant Hill Road and connects into a
15 -inch sewer that runs parallel to Grayson Creek to Milburn Drive.
This project involves installing approximately 12,000 feet of 15 -, 18 -, and 24 -inch relief
sewers and diverting the sewage away from the existing wet weather capacity- deficient
sewers. The relief sewer alignment is within city streets and extends from Pleasant Hill
Road, along Westover Drive, then Maureen Lane, Lucille Lane, and Kathleen Drive.
The improvements to the Pleasant Hill- Grayson Creek Trunk Sewer are included in the
fiscal year (FY) 2013 -2014 Capital Improvement Budget (CIB) on page 36. The current
CIB includes 5,000 LF of pipeline installation. The project has been expanded up to
approximately 12,000 LF due to the City's paving plans. The revised sewer renovation
program in the City of Pleasant Hill will be included in the FY 2014 -15 CIB and ten -year

plan. Staff has conducted a cash -flow analysis of the Capital Improvement Program
budget and concluded that adequate funds are available for this project.
Staff has concluded that this project is exempt from CEQA under District CEQA
Guidelines Section 15302, because it involves replacement of existing sewer facilities at
substantially the same locations and with the same purpose and level of activity as the
facilities being replaced. Any capacity increases are for non - growth inducing, wet
weather, or maintenance purposes. This project also is exempt under District CEQA
Guidelines Section 15061(b)(3), since it can be seen with certainty that there is no
possibility that the activity in question may have a significant effect on the environment.
This certainty is based on the District's past experience with numerous sewer
construction projects of this nature, the relatively short distances involved, and the
District's mitigating construction specifications. These specifications are standardized
general and special conditions that are made part of the project bid documents to
address environmental considerations, such as protecting trees and riparian areas, as
well as compliance with applicable federal, state, county, district, municipal and local
laws, ordinances, orders, and regulations. Approval of this project will establish the
Board of Directors' independent finding that this project is exempt from CEQA.
COMMITTEE RECOMMENDATION: The Engineering & Operations Committee
reviewed this project at its February 11, 2014, meeting and recommended project
approval for CEQA/permitting purposes.
RECOMMENDED BOARD ACTION: Approve the Pleasant Hill- Grayson Creek Trunk
Sewer, District Project 8412, and direct staff to file a Notice of Exemption with the
Contra Costa County Clerk.
