Staffreport
RECOMMENDATIONS
Staff recommends acceptance of the work, filing of the Notice of Completion, and upon completion to the satisfaction of the City Engineer of the one-year maintenance period, authorizing the City Manager to release the maintenance bond for the subject project.
BACKGROUND
In 1995, the City completed a comprehensive Sanitary Sewer Master Plan that identified sanitary sewer system deficiencies throughout the city. Using the information from the Master Plan as well as further investigation and inspections, the Engineering and Transportation Department compiled and categorized a list of sewer repair projects. Pipelines selected for improvement were evaluated by staff to determine the appropriate repair method ranging from in-place rehabilitation to replacement and relocation.
Repairs to sewer mains located in the public right of way and on private properties within existing easements were completed previously. This project focused on the remaining sewer repair locations. Before repair work commenced, new easements were successfully acquired from property owners. This project provided improvements at five locations as follows:
· Between Breed Avenue and Beverly Avenue, the backyard sewer was lined from Dowling Boulevard to Broadmoor Boulevard and the collapsed sewer south of Dowling Boulevard was relocated into the right of way;
· At Kenilworth Avenue, a sewer extension was installed in the street to improve access;
· At Sandelin Avenue, a sewer main was enlarged and several manholes improved;
· At Cleveland Street/Whelan Avenue, sewer mains were replaced and a new bypass installed in Cleveland Street; and
· The entire length of the View Drive easement line was rehabilitated using a cured in-place lining system, access extensions were added at two locations, and manhole access on the steep hillside was improved.
Analysis
The project is complete. These improvements will increase system reliability, reduce the frequency of required maintenance, and provide the access necessary to allow for more efficient maintenance, thereby reducing overall maintenance costs.
Current Agency Policies
Ensure well-maintained sewer facilities.
