HomeMy WebLinkAbout01-19-2016 Item 10 - Approval of Final Wastewater Collection System Infrastructure Renewal Stragegy
Meeting Date: 1/19/2016
FROM: Carrie Mattingly, Director of Utilities
Prepared By: Dave Hix, Deputy Director, Wastewater
Jennifer Metz, Utilities Projects Manager
SUBJECT: APPROVAL OF FINAL WASTEWATER COLLECTION SYSTEM
INFRASTRUCTURE RENEWAL STRATEGY
RECOMMENDATION
Approve the Negative Declaration and the Final Wastewater Collection System Infrastructure
Renewal Strategy.
DISCUSSION
Background
City staff worked collaboratively with Water Systems Consulting, Inc., (WSC) to prepare the
Draft Wastewater Collection System Infrastructure Renewal Strategy (Renewal Strategy). The
key issues addressed by the Renewal Strategy are the aging collection system, inflow and
infiltration (I/I), and capacity assurance. The Renewal Strategy:
1. Develops a method the City can use to identify and prioritize pipelines for rehabilitation;
and
2. Determines the length of pipeline the City should rehabilitate/upgrade each year to keep
the collection system functional, assure capacity and minimize Sanitary Sewer Overflows
(SSOs); and
3. Identifies programs the City can implement to reduce I/I, especially I/I from private
sewer laterals; and
4. Recommends monitoring to assess the performance of the Renewal Strategy to assure the
money being spent is achieving the desired goals.
The City Council previously reviewed the Renewal Strategy at a study session on May 5, 2015.
The Renewal Strategy presents a plan to guide policy, operations, and asset management
planning decisions in an efficient and cost effective manner. The Renewal Strategy features a
framework to be utilized with future budgeting and capital planning to address the aging
collection system and capacity assurance.
ENVIRONMENTAL REVIEW
Following the May 5, 2015, study session, an Initial Study was prepared by staff for the
Wastewater Collection System Infrastructure Renewal Strategy in accordance with the California
10
Packet Pg. 210
Environmental Quality Act. No potentially significant environmental impacts were identified for
this project and a Negative Declaration is recommended for adoption.
FISCAL IMPACT
There is no immediate fiscal impact associated with this recommended action. Wastewater
collection system improvements are incorporated into and prioritized through the sewer fund’s
capital improvement plan process. This process takes place during the development of each
financial plan. The Master Plan will inform the 2016 update of sewer development impact fees
and future rate setting.
AVAILABLE FOR REVIEW IN THE COUNCIL OFFICE
1. Final Wastewater Collection System Infrastructure Renewal Strategy, December 2015,
prepared by Water Systems Consulting Inc.
2. Negative Declaration, dated December 16, 2015.
