TO: BOARD OF SUPERVISORS, as the Governing Body of the Contra Costa County Flood
Control and Water Conservation District.
FROM: J. MICHAEL WALFORD, CHIEF ENGINEER
DATE: April 7, 1987
SUBJECT: Drainage Area 56 Lindsey Basin Design, Project No. 7566-6D8462-86.
Specific Request(s) or Recommendation(s) & Background usti kation
I. RECOMMENDED ACTION:
Approve consulting services agreement with John Carollo Engineers for engineering
services for the Lindsey Storm Water Detention Basin.
II. FINANCIAL IMPACT:
The maximum cost to the Flood Control District which is not to be exceeded without
written approval by the Chief Engineer is $192,150.00, which is available from local
drainage fees.
III. REASONS FOR RECOMMENDATION/BACKGROUND:
The proposed detention basin and associated discharge system are significant
components of the drainage plan for Drainage Area 56 which was adopted by the Board
in January, 1982. The proposed drainage improvements are required to safely store
and convey storm water runoff as the area continues to develop. Lack of an adequate
drainage system could cause flooding within the area and expose the County to
liability.
The services of a consultant are required to complete the design because insufficient
staff presently exists to accomplish the work with County forces. Interviews were
conducted with four engineering consultants, and John Carollo Engineers was selected
and submitted an acceptable proposal .
IV. CONSEQUENCES OF NEGATIVE ACTION:
If engineering services are not provided by consultant, the completion of final
construction plans will be delayed. In the event this project is not awarded for
construction by December 31 , 1987, the County will lose $500,000 in funding to be
provided by the Southern Pacific Railroad.
