RECOMMENDED ACTION:
Adopt Resolution No. 9 9 8
Avenue Widening, Project No. 3215.
appropriating additional funds for the construction of La Costa
ITEM EXPLANATION:
On February 10, 1998, the City Council awarded a contract in the amount of $6,624,624 to C. A. Rasmussen for the construction of La Costa Avenue between El Camino Real and l-5. As of this
date, the City has issued 20 change orders, 13 of which are paid from City contingency funds which have been exhausted. The major reasons for depletion of City contingency funds were the need to
rephase the project to enhance safety and unanticipated soils conditions requiring redesign of
retaining walls.
Staff recommends that additional funding be provided for asphalt paving on the project. The original
plan for the project was to preserve and reuse as much of the existing pavement as possible. Since
completion of the road widening plans, three factors have arose that, in concert, have changed the
best strategy for paving the project.
0 The original design for the asphalt pavement was based on cross-section measurements of the existing roadway that have been found to have some errors that would require the
existing pavement to be ground before being paved.
0 .The existing pavement has deteriorated as consequence of time, heavy loads during construction, and an extraordinarily wet winter (97-98).
a Construction of a new sewer cut through the existing pavement resulting in less salvageable
pavement and edge cracking of the existing pavement.
The combination of these factors has changed the most cost-effective solution from preserving and
reusing as much of the existing pavement as possible to removing the portions of pavement impacted by the preceding factors and replacing them with new asphalt pavement. In the long
term, the new asphalt pavement will provide a longer lasting street and best serve the public. It is estimated that this extra work will cost up to $295,000. The contingency for paving needs to be
increased by that amount.
Also, it is recommended that an additional $100,000 be added to the contingency to cover any
additional unforeseen items that may arise. The total recommended additional appropriation, therefore, is $395,000.
