required today.

approximately half the time of the contract allowed 30 working days. A summary of the
contract cost is as follows:

After the project was awarded and prior to work, the Contractor recommended a
change in the repair. Instead of the conventional export and import of materials to
repair the slope, the Contractor suggested that a. geo -grid be installed and that the
material on -site be reused. In addition, they suggested using a jute mesh on the
hillside to protect the landscape plantings. These options were reviewed and
subsequently approved by the project geotechnical engineer. No additional costs were
incurred for upgrading to the geo -grid and adding the jute mesh in lieu of importing and
exporting materials. Full payment was made on all bid items in the amount of $62,777.

Environmental Quality Act (CEQA) pursuant to Section 15302 of the CEQA Implementing
