As envisioned, the original 12.9 -acre restoration of the middle portion of the Big Canyon
Nature Park included clearing a 6.8 -acre portion invaded by non-native Brazilian Pepper
Trees and restoring this area with native trees and plants. The remaining 6.1 -acre area
was planned for selective removal of individual Brazilian pepper trees and other
non-native trees found within healthy groves of willows.
However, during initial clearing operations that allowed the design consultant's biologists
to investigate deep into the forested area, four acres of willows were found to be infested
with the polyphagous shot hole borer that required removal. (See Attachment A, Location
Map.) This increased the total clear-cut acreage to 10.8 acres, a 60 percent increase over
the originally anticipated 6.8 acres.
The extra budget needed to clear and restore this additional four acres was funded
through the grant -eligible contingency; no additional City of Newport Beach funds were
required. The additional work included chipping cut trees, hauling -off mulch for disposal,
stockpiling and solarizing the chipped infested -willows, grading to remove roots and
debris, applying soil supplements, installing temporary irrigation, and providing additional
plants and hydroseed. The City Council approved the increase of the contingency to
36 percent on November 24, 2020.
The contracted work has now been completed to the satisfaction of the Public Works
Department. The summary of the overall construction cost follows.

The final contract cost was $1,303,338.34, which was approximately 32 percent higher
than the original bid amount, of which about three-fourths of the additional costs were
associated with restoring the additional four acres of the park. There were 23 contract
change orders approved for the project.
A summary of the project schedule is as follows:
Estimated Start of Construction per Annual Baseline Schedule

Actual Substantial Construction Completion Date
12/26/2020
Extended Contract Completion Date Inclusive of Extra Work
03/21/2021
Construction was completed substantially ahead of schedule, in large measure due to
ECI prioritizing the project and committing full crews for the entire duration of the project.
After the construction was completed, ECI was required to establish and maintain the
installed plants for a 120 -day duration, which started on December 26, 2020 and was
successfully completed on April 22, 2021.
