AGENDA STATEMENT
City Council Meeting Date: May 24, 1993
SUBJECT:
Approving Agreement Between City of Dublin and Alameda
County Flood Control and Water Conservation District for
Funding of Pervious Concrete Project

RECOMMENDATION: (7 I~dopt Resolution approving this agreement with the Alameda
~' County Flood Control and Water Conservation District
FINANCIAL STATEMENT:
Cost to the City will be reimbursed by the grant funding.
DESCRIPTION: The Alameda County Urban Runoff Clean Water Program
(ACURCWP) faces the monumental task of cleaning up the County's storm water for
discharge into the San Francisco Bay through a National Pollution Discharge
Elimination System permit. As one way to accomplish this major undertaking, the
ACURCWP put aside $300,000 to encourage agencies to propose pilot projects to
improve the quality of storm water in a cost effective way that, if effective, other
agencies could use.
The City of Dublin's Public Works Department developed a pilot project proposal to
install a pervious concrete storm water filter in the Shannon Park parking lot, and
the City Council, at their meeting of September 28, 1992, authorized Staff to submit
this pilot project to ACURCWP. The ACURCWP subsequently approved the City's project
for funding. Pervious concrete has been utilized widely in England and Florida for
groundwater recharge for several years with considerable success. However, pervious
concrete has not been used for the purpose of improving the quality of storm water.
This pilot project could show that pervious concrete can be used to improve the
quality of storm water in a cost effective way.
Pervious concrete is a porous mixture of gravel and concrete which allows storm
water with small polluting particles to flow through the concrete. A layer of sand,
approximately 1 to 3 feet in depth, would be installed under the pervious concrete
to act as a filter. Leaves and larger particles will stay on top of the concrete
and be picked up by the parking lot sweeper, and the sand would filter out
waterborne pollutants. The pervious concrete would reduce the maintenance cost of
cleaning the storm drain inlet by keeping leaves and debris from entering the storm
drain. It is estimated that the sand will need to be replaced every 20 to 30 years.
After removal, this same sand could be used for roadway construction. The pervious
concrete will be cast in blocks so they can be removed and reused after replacing
the sand filter.
The total estimated project cost, including staff time, is $33,600. If the project
shows that the quality of storm water can be improved in a cost effective manner, it
could be used not only in our local area/but nationwide.
Staff recommends that the City Council adopt the resolution approving the agreement.
The agreement will cover the cost of the project by ACURCWP.
