COUNCIL AGENDA REPORT ITEM NUMBER:
FROM:
Dave Romero Wayne Peterson Prepared by: �K ie� Opalewski
Public Works City Engineer Parking Manager
SUBJ:
Plans and Specifications for Crack Repair Project for Palm Street
and Marsh Street Parking Structures.
CAO RECOMMENDATION:
By motion, approve the plans and specifications for crack repair
for the Palm Street and Marsh Street Parking Structures and
authorize soliciting of bids and awarding of contract if lowest
responsible bid is within Engineer's estimate.
BACKGROUND:
Since the completion of the Palm Street Parking Structure in March
1988, there have been a number of structural cracks in the walls
and floors. This is common with structures of this construction.
These cracks are easily penetrated by water which is causing
deterioration of the concrete and metal reinforcement in the walls
and floors. If allowed to continue unchecked, this water
penetration could cause serious damage and costly reconstruction
to the structure. There have been similar cracks in the floor area
of the new Marsh Street facility, but to a lesser degree.
DISCUSSION:
Through an epoxy injection system the floors and walls of both
structures can be sealed to prevent further water damage.
Approximately 3100 linear feet will have to sealed in the Palm
Structure and 200 linear feet in the Marsh Structure. This
application process in the most cost-effective and can be done with
a minimum of disruption to the operations of each structure.
The life expectancy of this project is unknown because of the
nature of post-tension concrete contruction. Periodic inspections
will be required to determine if additional repairs are needed.
CONCURRENCES:
The Engineering and Parking Divisions concur with the
recommendation to epoxy seal the walls and floors.
FISCAL IMPACT:
The Engineer's estimate for the project is $42,000. This is a new
project and monies have not been allocated for this repair work in

the current budget. Funds will have to be allocated from the
undesignated fund balance of the parking program. As reflected in
the recent mid-year budget review, adequate balances are projected
at year end to fund this project. However, the long-term financial
status of the parking system continues to be a concern, and any
unprogrammed outlay reduces the funds available for future capital
purchases, such as acquisition of a third parking site.
ALTERNATIVES:
1. Delay the project to a later date
2. Reduce the scope of the project
3 . Cancel the project
PROS AND CONS
It is possible to postpone the project, especially in light of
our limited rainfall. However, any additional moisture from
condensation or light rain will only accelerate the concrete
deterioration. The longer we wait, the more costly for future
repairs. Repairing only part of the cracks or completing only one
structure would be less expensive in the short-term, but more
costly in the long-term since the bidding and contract process
would have to be repeated. Cancelling the project would be short
sighted and only cause more serious problems in the future.
Plans and specification are available in the Council Office for
review.
