FIND that the Acquisitions of Property Rights for the Oakley-Trembath Detention Basins
project is a California Environmental Quality Act (CEQA) activity that was covered within
the scope of the previously approved East Antioch Creek Watershed (Drainage Area 56)
program EIR (1981) (Section 15168(c)(2)), and
FIND, on the basis of the Initial Study Negative Declaration and all comments received and
staff responses contained herein, that there is no substantial evidence that the project will
have a significant effect on the environment, and
AUTHORIZE the Real Property Division to initiate the acquisition process for the purchase
of the necessary property rights to construct the Oakley-Trembath Detention Basins, and
AUTHORIZE the Director of Department of Community and Development to file a Notice
of Determination with the County Clerk, and
AUTHORIZE the Chief Engineer to arrange for payment of a $50.00 fee to the County

RECOMMENDATION(S): (CONT'D)
for processing.
FISCAL IMPACT:
There is no impact to the County General Fund. The estimated project construction cost
is $6,000,000.00 funded 100% by Drainage Area 56 funds (Fund 256600).
BACKGROUND:
The Contra Costa County Flood Control and Water Conservation District (District) in
conjunction with the City of Antioch proposes to expand an existing detention basin
(Oakley) and construct a new detention basin (Trembath), both located along East
Antioch Creek in the East Antioch Creek Watershed (Drainage Area 56) within the city
limits of Antioch. The purpose of this project is to provide 50-year flood protection to
areas downstream of Highway 4 and to reduce the threat of flooding in Lake Alhambra
(located approximately 0.6 mile downstream). Recent development in the upper
watershed has resulted in the need for greater flood protection in the downstream
residential neighborhoods.
Prior to constructing the detention basins, the District needs to acquire property rights
from non-District-owned properties located within and adjacent to the basin areas, which
are subject to temporary inundation during storm events. Specifically, the District will
obtain various property rights which will legally allow the District to construct and
maintain these basins and associated drainage structures to ensure that floodwaters can
flow through and to ensure there will be no developments or encroachments that would
impede flood flows.
Acquisition of property rights is a real property transaction that does not involve direct
physical changes to the environment. While the Drainage Area 56 program-level
Environmental Impact Report (EIR) (1981) considered property rights acquisitions
necessary for these two basins, the District must determine, pursuant to Section 15168(C)
of the California Environmental Quality Act (CEQA) Guidelines, whether this activity
would have effects that were not previously examined in the EIR.
Actual construction of the Oakley-Trembath Detention Basins will be evaluated in a
separate project-specific CEQA document.
CONSEQUENCE OF NEGATIVE ACTION:
Delay in approving the project will result in a delay of design and construction and may
jeopardize funding.
