CITY OF SEBASTOPOL CITY COUNCIL
AGENDA ITEM REPORT FOR MEETING OF: April 7, 2026
======================================================================================== To: Honorable Mayor and City Councilmembers
From: Oriana Hart, Public Works Director
Responsible Department: Public Works Department
Subject: Notice of Completion – Emergency Sewer Main Replacement on South High Street Piazza Construction.
======================================================================================== RECOMMENDATION(S):
The item is to request Council Adopt Minute Order accepting improvements for public use and authorize staff to file a Notice of Completion for the Emergency Sewer Main Replacement Project on South High Street.
EXECUTIVE SUMMARY:
This item requests that the City Council accept the completed emergency sewer main replacement project on South High Street and authorize the filing of a Notice of Completion.
BACKGROUND AND DISCUSSION:
In March 2026, the City Council declared an emergency due to the failure of approximately 156 linear feet of 6-inch clay sewer main located on South High Street between Calder Avenue and Maple Avenue.
The pipe exhibited significant deterioration, including root intrusion, structural failure, and evidence of sewage exfiltration, posing a risk to public health, the environment, and continuity of sewer service.
The City authorized emergency repairs and executed a contract with Piazza Construction to complete the work. Work started on March 19, 2026, and substantially complete on March 27, 2026.
STAFF ANALYSIS:
The failed segment of sewer main on South High Street was part of the City’s aging clay pipe system and had reached the end of its useful life. Field observations and inspection confirmed that localized repairs would not provide a reliable long-term solution, and full replacement of the segment was necessary to restore system integrity.
Due to the emergency nature of the failure, the City proceeded under Public Contract Code Section 22050 to complete the work without delay. This approach minimized the risk of a sanitary sewer overflow, service disruptions to nearby properties, and potential environmental impacts.
Piazza Construction was able to mobilize quickly and complete the work efficiently. The replacement of this segment has improved the reliability of the system and reduced the likelihood of near-term failures in this location.
With construction complete and the system fully operational, acceptance of the project and filing of the Notice of Completion is the appropriate next step to formally close out the contract.
