Status of Brentwood Truck Bypass
A $1.7 million Caltrans project to reroute Highway 4 around downtown
Brentwood is scheduled to begin in 1988, but Caltrans does not have
sufficient staff to proceed with the project. Local agencies with staff
certified to work on federally-funded road projects (e.g. the County) could
design and construct the project for Caltrans. Caltrans, Brentwood, and the
County have drafted a Cooperative Agreement that would allow the County, on
the behalf of Caltrans and Brentwood, to provide staff support and
administer all contracts to complete the project. It is likely that the
agreement will be executed within several months. At Caltrans'
recommendation, County staff will advertise next week for consultants to
prepare construction plans.
Status of Highway 4 Interim Project
Based on the preliminary construction plans, the estimated cost to complete
the Highway 4 interim project has increased to $2.8 million. The City of
Pittsburg is proposing that we finance the project by issuing bonds secured
only by annual appropriations (no collateral is required) . Using this
scheme, the cost to finance $2.8 million over a five year period is
$3,482,000. Apportioning this cost according to future housing construction
in Antioch, Pittsburg, and unincorporated eastern Contra Costa County would
amount to $341/unit. Financing the loan over seven years would cost
$3,735,000, or $261/unit (assuming housing construction continues at 2039
units/year) .
