SPECIFIC REQUEST(S) OR RECOMMENDATION(S) &BACKGROUND AND JUSTIFICATION
I. Recommended Action:
APPROVE and AUTHORIZE the Chief Engineer to execute contract Amendment No. 1 to Consulting Services
Agreement with Kleinfelder, Inc.,to increase the payment limit to$8,570 for 1) geotechnical services in the amount
of$2,270 and 2)to perform a preliminary sedimentation study of West Antioch Creek for the Contra Costa County
Flood Control and Water Conservation District in the amount of$6,300.
II. Financial Impact:
The estimated additional contract cost is $8,570 funded by Drainage Area 55 fees. (100%).
III. Reasons for Recommendations and Background:
The increased payment limit for additional traffic control and drilling to avoid an unmarked underground utility and
to complete the project.
The project's effect on sediment transportation into the Delta wetlands needs to be evaluated for the permit
requirements of the Army Corps of Engineers and Central Valley Regional Water Quality Control Board.
IV. Consequences of Negative Action:
Without an increase in the payment limit for geotechnical services, there will not be sufficient funds to complete
the geotechnical study. The Sediment Transportation Study is required to comply with permit requirements of
Central Valley Regional Water Quality Control Board.
