Consulting Services Agreement between City of San Leandro and Last revised May 2021 Freyer & Laureta, Inc. for San Rafael St. Force Main Replacement Exhibit A – Page 1 of 2 EXHIBIT A SCOPE OF SERVICES Project Description The City of San Leandro proposes to replace the San Rafael Lift Station force-main and replace/upgrade two force-main valve covers located on Wicks Boulevard. The San Rafael Street Lift Station was constructed in circa 1947 and provides sanitary sewer service to approximately 100 properties located between San Rafael Street and Grand Avenue. The lift station’s force-main extends 700 feet to its discharge point in Sybil Avenue. The force main is of cast iron construction and is heavily corroded. It has reached its useful life and is need of replacement. Wicks Boulevard Lift Station and Force Main were replaced in 2009. The force main passes through a series of valves located in vault structures beneath Wicks Boulevard roadway. The covers to the vaults, subject to traffic loading including heavy trucks have become loose and rattle w hen driven over.
