II. Fiscallmpact:
There will be no impact to the County General Fund. This consulting services contract will be paid for by
Drainage Area 56 funds.
III. Reasons for Recommendations and Background:
The Oakley and Trembath Creek Basins are regional detention basin facilities planned for remediation of
storm waters generated by the future urban development in the City of Antioch. Both basins are large
facilities capable of holding large quantities of storm waters. The State Division of Safety of Darns has
required the consultant to perform additional testing and mapping above what was originally included by the
original contract. All of the testing must be done by a certified geotechnical engineer.
IV. Consequences of Negative Action:
If this Board Order is not approved,the consulting services agreement amendment will not be executed and
future construction of the basins will be delayed.
