into readiness to accept storm water flows. The second phase of the work completed
included slope backfill, planting of various California native shrubs and trees, and
hydroseeding. The plant establishment is complete and contractor plant maintenance
will be finished prior to the retention release.
The contract has now been completed to the satisfaction of the Public Works
Department. A summary of the contract cost is as follows:
Original bid amount: $796,518.50
Actual amount of bid items constructed: $738,463.00

extended date.
