As part of the valve exercising program, valves in the water distribution system are regularly exercised and inspected to ensure that they will shut down in an emergency or for a planned shutdown. Valves that are broken or not working properly are then

valves on Santa Anita Avenue between Duarte Road and Orange Grove Avenue were
not fully operational and needed to be replaced. On March 21, 2017, the City Council approved a contract with T.E. Roberts, Inc. for the
Valve Replacement Project. The work performed included excavating in the street and
right of way on Santa Anita Avenue between Duarte Road and Orange Grove Avenue,
removing two damaged 30-inch gate valves, and installing two new 30-inch butterfly

that did not change the scope of the project. Below is a breakdown of contract change orders.
