BACKGROUND: The Sleepy Hollow Pumping Station Upgrades Project upgraded
mechanical and electrical equipment to reduce the potential for sewage overflows, to
reduce maintenance, and to increase operating efficiency. The pumping station is
located at Sleepy Hollow Elementary School in Orinda.
Sleepy Hollow Pumping Station is over 50 -years old; the improvements made under
this project will extend the useful life of the station for many years into the future. This
project replaced corroding conduits and electrical cabinets, and also relocated these
cabinets to a more accessible location to comply with safety standards. The wet well
was coated to preserve the concrete, and the emergency discharge bypass connection
was replaced. This project installed new dedicated electric and water services to the
pumping station.
To save design and bid costs, two other pumping station projects were completed
under the Sleepy Hallow project. The first project installed a new 125 kW standby
generator at Concord Industrial Pumping Station. The second project completed was
abandonment of the Bates Avenue Pumping Station. This station was located in
Concord and was constructed in 1968. In the late 1980s, flow was diverted from the
Bates Avenue Pumping Station to Concord Industrial Pumping Station. The

abandonment of the Bates Avenue Pumping Station precludes maintenance at the
station. Also, electrical and mechanical equipment was salvaged for future District use.
On April 1 , 2010, the Board of Directors authorized the award of a contract for the
construction of the project to Pacific Mechanical Corporation. The Notice to Proceed
was issued on April 30, 2010. The work was substantially completed on December 2,
2010. The remaining items of work consist of minor punch -list items, which do not
affect the project acceptance.
Immediately upon acceptance, the Contractor is relieved of the duty of maintaining and
protecting the Contract work. Guaranty and warranty periods required by the Contract
and the statutory period for filing of liens and Stop Notices start on the date of
acceptance by the Board of Directors. Final payment to the Contractor is made after
expiration of the statutory period for filing of liens and Stop Notices, provided no liens or
Stop Notices have been filed, and provided the punch -list items have been completed.'
The total authorized budget for the project is $820,860. The budget includes the cost of
engineering design, construction management and inspection, testing services, change
orders, and contractor services. An accounting of the project costs will be provided to
the Board at the time of project closeout. It is appropriate to accept the contract work at
this time.
RECOMMENDED BOARD ACTION: Accept the contract work for the Sleepy Hollow
Pumping Station Upgrades Project, District Project 6960, and authorize filing of the
Notice of Completion.
