DISCUSSION
The Public Works Services Department is responsible for the maintenance and repair of
City streets. Annually, staff evaluates all City streets and detemiines necessary repairs
and found that the streets north of Elkins Drive in the Highland Oaks area were
damaged from Stone Pine trees. Over the years the health of the Stone Pine trees had
been declining and their roots were causing extensive damage to the streets, curbs and
gutters and private property. Staff also worked with a licensed arborist who stated that
the years of cutting the tree roots to repair streets and curb and gutter and driveways,
has contributed to the decline of the health of the trees and could destabilize the trees.
As a result, the condition of the streets affected with tree root damage posed both
potential pedestrian and driving hazards.

On January 4, 2011, the City Council awarded a contract to S.J. Grigolla Construction,
Inc. for Phases 1 and 2 for repairs to concrete and asphalt damaged by Stone Pine tree
roots in the amount of $181,700. At the same time, a separate contract for the removal
and replacement of the Stone Pine trees was also awarded, which was accepted by the
City Council as complete on June 7, 2011.
The terms and conditions of the street rehabilitation contract with S.J. Grigolla
Construction, Inc. have been complied with and the work has been performed to staffs
satisfaction. Therefore, staff recommends that the City Council accept all work
performed by S.J. Grigolla Construction Inc. as complete and authorize the final
payment to be made in accordance with the contract documents, subject to retention of
$17,271.80. This amount reflects the original contract amount of $181,700 minus
quantity changes totaling $8,982 or -4.94% below the original contract amount.
As with most Capital Improvement projects, the original contract amount is awarded
based on the project quantities from the initial engineer's estimate and the low bidder's
unit bid prices. During construction it was determined that less asphalt, curb and gutter
replacement was needed; as a result, there was a net savings in the overall contract
cost.
ENVIRONMENTAL IMPACT
This road repair project is considered a Class 1 exemption as defined in Section
15301(c) of the California Environmental Quality Act since the project consists of the
maintenance of existing public streets but does not involve expansion of the existing
use of the streets.
FISCAL IMPACT
Sufficient funds are budgeted in the 2010/2011 Capital Improvement Program for this
project.
RECOMMENDATION
1. Accept all work performed by S.J. Grigolla Construction, Inc. for the repair
of streets with Stone Pine trees as complete.
2. Authorize final payment to be made in accordance with the contract
documents, subject to a retention of $17,271.80.
