RECOMMENDED ACTION:
MTG, 5/25/93 PALOMAR AIRPORT ROAD EAST WIDENING CITY AT1
CITY MGI PROJECT NO. 3166
City Council authorize City Manager to approve a contract change order increas
imported borrow by 30,000 cubic yards for the Palomar Airport Road East Widen
Project No. 3166.
ITEM EXPLANATION:
On April 5, 1993, construction began on the Palomar Airport Road East Widening Projl
Shortly after initiation of clearing operations, representatives of the Fish and Wildlife Sen
sighted a California gnatcatcher crossing the easterly end of the project. The staff 1 notified to restrict the contractor’s operation and reinitiate biological surveys of the ai
The updated surveys have identified a nesting pair of gnatcatchers north and east of
intersection of Palomar Airport Road and Business Park Drive.
Based on discussion with Fish and Wildlife, a 1OA Permit will be required to modify
habitat area. Redesign of the project in the nesting area will be required. Dur
processing of the 1OA Permit, no taking of habitat will be allowed. The impacted ai
provides approximately 40,000 cubic yards of fill material needed to maintain progress
the project. The inability to obtain fill material would seriously impact the construct
progress resulting in significant delay. In order to avoid those delays, staff
recommending increasing imported borrow for the project to 30,000 cubic yards at
estimated net cost of $152,400.
ALTERNATIVES ANALYSIS:
Staff reviewed several alternatives to the proposed action in developing I
recommendation:
1. SusDend Work in ImDacted Areas Until Permit Obtained
This option would prevent a significant fill area from being completed which is v
to installation of utilities on the critical construction path. The length of the de
is indeterminate at this time, but could be several months. It is likely that even M
the permit, up to 20,000 cubic yards of fill will be lost to mitigation efforts to proti the habitat.
Redesian the Palomar Airport Road Profile to Reduce Fill Reauiremei
This option would reduce the costs of the earthwork, but increases engineering E
survey cost by $25,000 to $40,000. This option would require negotiation o
significant change in the work with the contractor and likely involve a two to thr
week delay. The contractor has not been cooperative in the execution of chan
orders and would likely frustrate this process. It is staff’s opinion that the ris
involved in this approach outweigh the potential cost savings that might
accrued.
