COUNCIL AGENDA REPORT ITEM NUMBERe�
FROM: Michael D. McCluskey, Public Works Di ector#^
Prepared by: Barbara Lynch, Engineering Assistant'- //
SUBJECT: Higuera Street Bridge Study, Specification No. 93-67.
CAO RECOMM]MATION:
By motion,
1) approve the request for proposals for "Higuera Street Bridge Study,
Specification No. 93-67"
2) authorize staff to distribute the request for proposals
3) authorize the CAO to award a contract to the firm submitting the
best proposal if the cost is within budget
DISCUSSION:
With approval, staff will request proposals to complete a study of the
Higuera Street Bridge over San Luis Obispo Creek. This study will
determine improvements needed to prevent further deterioration and
restore adequate load limits.
Where San Luis Obispo Creek runs underground and crosses Higuera Street
there is a bridge which was built in 1911. This bridge forms _a portion
of what is commonly called the "undercity culvert". Because this
bridge is not visible aboveground, it has not been on the list of
bridges examined by state bridge inspectors semi-annually. After the
City advised the state of this omission, inspectors examined the bridge
in 1993. In November 1993, the state informed the City that its
inspection had revealed two problems: 1) portions of the bridge were
gradually deteriorating and 2) the bridge was not designed to carry the
loads allowed on it. The City has since reduced the bridge's load
limit, which prohibited truck and bus traffic.
There are federal HBRR grants administered by Caltrans available to pay
for 80 percent of the cost to rehabilitate or replace this bridge. A
field review with Caltrans structural engineers determined the
possibility of rehabilitation, a much less disruptive option. In order
to receive grants for design and construction, the City must first
complete a study to establish 1) the feasibility of rehabilitation and
2) the extent of work eligible for grant reimbursement.
FISCAL IMPACT:
The engineers estimate for this study is $25,000, and that amount was
appropriated in the 1994/95 budget (see page E-4) . A federal HBRR
grant has been approved and will pay up to $20,000 of the cost after
completion and acceptance of the study.
