BACKGROUND: To maintain and improve the condition of the City's wastewater system, the Department of Water Resources and Conservation annually replaces or rehabilitates deteriorating sanitary sewer mains throughout the City. The Water Street North Sewer Main Replacement Project involved replacing approximately 1,000 feet of severely deteriorated sanitary sewer main on Water Street North between Washington Boulevard and the Copeland Wastewater Pump Station to improve service and reduce maintenance costs. This project location is illustrated on Exhibit A. The City Council awarded the construction contract for this project to North Bay Construction (NBC) on hire 18, 2007. Shortly thereafter, lead -impacted soils were unexpectedly encountered on the construction site. On October 11, 3007, the City formally notified NBC to immediately suspend all work related to the project. The City then prepared a Soil Management Plan to identify the extent and location of lead -impacted soil, classify the soil as California hazardous or non -hazardous, and identify landfills available to accept the soil. On September 15, 2008, the City Council adopted resolution No. 2008-181 authorizing Change Order No. 1, which included handling of the contaminated soils and all work necessary to accommodate the sewer pipe re -alignment due to a request from the Sonoma Marin Area Rail Transit (SMART) to avoid displacement of the existing rail line. Construction began on October 13, 3008, and was completed on December 12, 2008. Informational notices for the project were sent to nearby residences and businesses before construction began. A copy of the notice is included as Exhibit B. Construction photographs are provided in Exhibit C. 2 DISCUSSION: Following the acceptance of the project, the City Cleric will file a Notice of Completion with the Sonoma County Recorder and the Finance Department will release the retention money to the contractor within 60 days. 4.

The design phase occurred in the O&M budget and the construction phase occurred in the CIP budget. A breakdown of the total costs between the two budgets, including design, geotechnical, construction management and construction is provided in Table 2.
