and 63-12.3)
The Board of Supervisors of Contra Costa County, as the governing body
of the Contra Costa County Flood Control and Water Conservation District, RESOLVES
THAT:
On November 24, 1981, this Board adopted its Resolution No. 81/1339 proposing
to establish Contra Costa County Flood Control and Water Conservation District
Drainage Area 56 consisting of that real property described in Exhibit 11 A11 , and
institute a drainage plan therefor.
This Board has considered the proposed ordinance and the report entitled
Impervious Surface Drainage Fee Ordinance submitted to the Board by the Public
Works Department on December 22, 1981 and amended on January 5, 1982.
On January 5, 1982, pursuant to Resolution No. 81/1339, this Board held
a hearing on the question of the establishment of said Drainage Area, institution
of a drainage plan therefor, and the adoption of a drainage fee ordinance. At
the time and place fixed for said hearing before this Board all written and oral
objections presented concerning the proposed Drainage Area, plans, and drainage
fee ordinance were considered.
This Board finds that any valid written protests filed do not represent
more than one-half of the assessed valuation of real property contained in the
proposed Drainage Area 56. This Board also finds that no written petition for
an election signed by at least 25% of the registered voters within proposed Drainage
Area 56 has been filed.
It appears from the affidavits of publication on file with this Board
that all notices required to be given for such hearing have been duly and regularly
given and all procedures to be followed have been followed all in accordance with
Section 11 and 12.3 of the Contra Costa County Flood Control and Water Conservation
District Act and in accordance with the provisions of Resolution No. 81/1339.
This Board has received no resolution or ordinance adopted by any affected
city requesting the exc l usion of territory from proposed Drainage Area 56.
This Board hereby CERTIFIES that the Environmental Impact Report submitted
to it by the Public Works Department as to the environmental impact of proposed
Drainage Area 56 has been completed in compliance with the California Environmental
Quality Act, and it has reviewed and considered the information contained therein.
This Board ACKNOWLEDGES that the Drainage Plan would have certain environmental
effects and ADOPTS the findings and mitigation measures expressed in Planning
Commission Resolution No. 51/1981 which mitigate those effects in the manner indicated
and is hereby included as Exhibit 11 B11 •
This Board hereby FINDS that good cause exists for the establishment
of Drainage Area 56 and orders that Contra Costa County Flood Control and Water
Conservation District Drainage Area 56 is established, consisting of the real
property described in Exhibit 11 A11 • The drainage plan as shown on the map entitled
11 Drainage Area 56, Boundary Map and Drainage Plan 11 , dated October 6, 1981, proposed
to be instituted for Drainage Area 56 and on file with the Clerk of the Board
of Supervisors, Administration Building, Martinez, California, is hereby instituted.
RESOLUTION NO. 82/22

in said drainage area.

RESOLUTION NO. 51-1981
RESOLUI'ION OF THE PLANNIN3 CG1MISSION OF THE COUNTY OF CONTRA COSTA, STATE
OF CALIFORNIA, INCORPORATING FINDINGS AND RECOMMENDATIONS ON 'J'HE FINAL
EIR FOR DRAINAGE AREA 56 IN THE ANTIGO! ARFA OF CTNTRA COSTA COUNTY.
WHEREAS, pursuant to the provisions of Government Code 65450, public
hearings were held before the County Planning Commission on August 11,
September 29, and October 27, 1981 to consider and EIR for Drainage Area
56 in the Antioch area of Contra Costa County; and
WHEREAS, all th,= procedures of the California Environmental Quality
Act and the Contra Costa County Guide·lines to implement this Act have been
met, and the hereinafter listed ma itter was discussed fully with testimony
and docunentation presented by the public and various county, local and
state agencies;
WHEREAS, the EIR was prepared in connection with the Drainage Plan
including responses to comments which constitutes the Final EIR for the
project.
NOW, 'PHEREFORE, BE IT RESOLVED that the County Planning Canmission
at a regularly scheduled public hearing on December 8, 1981, makes the
following findings and recanmendations on the matter;
1. 11.Phe Dr aina9e Plan with i t:s proposed standards for implementation
will mitigate many of the impacts emnnerated in the Environmental
Impact Report.
2. The Drainage Plan has left significant areas in open space and
:i s protecting . the environmental resources of the area through
the design and standards of the Plan.
BE IT FUR'T'HER RESOLVED that the County Planning Commission having
reviewed the comments submitted in response to the EIR, finds that the
environmental doct.nnents consti tutin9 the Final EIR are adequate and provide
an environmental ana l ysis suitable for decision making on the project,
and the P l anning Commission certifies to the Board of Supervisors that
it finds the EIR to be adequate and that it has been canpleted in canpliance
with State Guidelines and County processing procedure for implementing
the California Environmental Quality Act; and
BE IT FUR'T'HER RESOLVED that the County Planning Corrnnission concurs
with the f i ndings of the EIR that the Drainage Plan would have certain
environmental effect:s and adopts the following findings and measures which
partially mitigate those ef fee ts in the manner indicated. This impact
1
RESOIDTION NO. 51-1981
follows the same sequence as identified in the sumnary of the Draft EIR.
Land Use: Legal, Pol~, and Institutional Constraints
Impac~ Alternates 1 and 3A proposed for Reach #1 will have the adverse
impact of loss of land designated as industrial in the Antioch General
Plan. This is due to the relocation of the creek channel and outfall at
the San Joaquin River to the site of the abandoned Hickmott Cannery.
Mitigation. Alternate 2 will be implemented for Reach #1 to avoid
loss of developable land at the Hickmott site and to preserve the existing
marsh as open space.
Impact. An indirect impact of the drainage improvements will be the
increased pressure to develop areas designated for agriculture and open
space in the General Plan of Antioch. The creek improvements will eliminate
the constraint of inadequate flood control and drainage in those areas.
Mi tiqation. "Agricultural preserve" contracts should be encouraged
in the I.JR)=r reacres of the watershed to mitigate against possible encroachment
of residential develo:pnent on open space and agriculture. This mitigation
measure is within the responsibil i ty and jurisdiction of the County or
the City and not the Flood Control District.
Impact. The California Department of Fish and Game has jurisdiction
over the project and states t h at alternates 3A and 3B for Reach #1 are
in conflict with the Wetlands Policy of the State of California. The filling
or modification of wetlands in this reach will adversely affect the wildlife
ancl marsh habitat.
Mitigation. 'I'he California Department of Fish and Game recaranends
alternate 1 or 2 for Reach #1 and suggests the following mitigation measures
be incorporated into the project to mitigate for potential adverse impacts
upon downstream water quality and to protect the riparian habitat of the
creek.
1. Alternate 2 will be implem.ented for Reach #1.
2. No development should be permitted within a 100-foot wide strip
along each side of the cre,ek from the railroad bridge to Wilbur
Avenue. The point of measurement for this corridor should begin
at the top of the bank of the open water creek to provide for
a uniform setback and an undisturbed area of suff icient size. This
2
RESOUJTIOO NO. 51-1981
mitigation measure is within the responsibility and jurisdiction of the
County or the City and not the Flood Control District.
3. An adequate flood control right of way will be provided adjacent
t .o the creek to ensure future flood control needs without having
to destroy creek vegetation.
4. All disturbed areas wi l l be replanted with native, dro1.ght resistant
vegetation, including the larger, slower growing trees seldom
planted by homeowners such as sycamore, cottonwood, valley oak,
blue oak and coast live oaks.
5. An adequately designed corridor should be incorporated into the
project plan to provide for wildlife movement and reduce conflict
with developnent. This mitigation measure is within the responsi-
bility and jurisdiction of the County or the City and not the
Flood Control District.
6. Grading and other land preparation will be restricted to the
period from May to October as much as possible.
7. 1Ul work in or near the stream will be confined to the period
fran June 1 to October 1 aE: much as possible.
8. All erodible slopes will be hydranulched or otherwise stabilized
by October 1.
9. Sediment detention basins will be large enough to adequately
impound maximun runoff consistent with project design.
10. 'rhe future maintenance of the detention basins throughout the
1i f e of the project will be addressed.
Impact. The California Regional Water Quality Control Board (CRWQCB)
has reported that there are ix,tential impacts of erosion and deteriorated
water quality as a result of the pro:iect.
Mitigation. The CRWQCB recommends the following mitigation measures:
1. 'l'he project: will have an erosion control plan which emphasizes
methods of controlling erosion and sedimentation.
2. Construction activities will be phased in order to canplete all
3
•
RESOLU'J'ICN NO.51-1981
earth disturbing activities during the dry season as much as
possible ..
3. All dist1Jrbed areas will be stabilized by installation of tarp:>rary
and permanent erosion control measures prior to the rainy season.
Impact. The Lake Alhambra Property Owners' Association has stated
that the primary impacts of the project are beneficial to the homeowners
around Lake Alhambra. However, t he specific impacts of erosion in the
upper watershed, control of water levels in Lake Alhambra and maintenance
of the new weir must be addressed.
Mitigation. ·rhe Lake Alhambra Property Owners' Association has prcposed
the following mi tiqation measures:
1. The wateir level in Lake Alhambra will remain under the control
of the Property Owners' Association.
2. A stron9 erosion control ordinance should be adopted by the City
of Antioch and Contra Costa County to further control sedimentation
with thei E:ast Antioch Creek watershed. This mitigation measure
is within the responsibility and jurisdiction of the County or
the City and not the Flood Control District
3. Maintenance responsibil:i ties of the new weir will be addressed
in the Drainage Area Maintenance Plan.
4. The new extension of Lake Alhambra should be fenced or otherwise
secured to discourage pedestrian access. This mitigation measure
is within the responsibility and jurisdiction of the County or
the City and not t.he Floocl Control District.
Traffic and Circulation
Impact. The proposed new outfall to the San Joaquin River may be
incompatible with plans which the Atchison, Topeka and San ta Fe Railroad
has for convertin9 the wooden trestle in the San Joaquin River to an earth-
filled embankment.
Mitigation. 'I'he selection of an alternate for Reach #1 will be coordinated
with the Santa Fe Railroad plans for trestle conversions. Further environmental
analysis should be completed by Santa Fe Railroad Company to determine
specific impacts of trestle conversions.
4
~
RESOLUTIOO ID. 51-1981
Impact. The storm drain rights of way which will cross the properties
of Cal.Trans, Atchison 1, Topeka anc! Santa Fe Railroad and Southern Pacific
Railroad may have temporary impacts upon these transportation systems.
Mitigation. Additional mitigation measures will be considered fran
these property owners when specific design plans for the storm drain rights
of way havE? been canpleted.
Impact. The rural traffic of the area surrounding the proposed Lindsey
basin does not appear to warrant the construction of four-lane roads around
the detention basin s:i te at this time.
Mitigation. Fur ther traffic analysis should be canpleted to determine
the necessaryfuture roadway configurations in the vicinity of the proposed
Lindsey basin. This mitigation measure is within the responsibility and
jurisdiction of the County or the Ci t y and not the Flood Control District.
Services and Utilities
Impact. There are potential impacts with several pipelines and PG&E
high voltage towers located within the flood plain area.
Mi. tigation.
1. Specific mitigations for conflicts with utilities within the
watershed will be recanmended when final site plans for drainage
i mprovements have . been completed by the Flood Control District.
2. All grading and earthwork will be avoided near the PG&E high
voltage towers to prevent the need for reinforcing the bases.
·Archaeology
Impact. The excavation activity proposed for East Antioch Creek has
the potential to adversely af feet archaeological resources which may be
located in the area,, although no known sites presently exist within the
watershed.
Mitigation.
1. 'rhe Cultur.al Resources Facility at Sonana State University will
be notified if archaeological finds are encountered during exca-
vation.
2. Any subsurface archaeological materials found during excavation
will be evaluated by a qualified archaeologist.
5
•
RESOLUTION NO. 51-1981
Earth: Soils, Geology and Seismic Hazards
Impact. ~here are potential adverse impacts of subsidence, erosion
and slumping of the proposed earth embankments into the creek and basins.
Mitigation. Al l earth embankments will be compacted (as required
by Ordinance) to minimize subsidence, erosion and slumping into the creek.
Impact. Alternates 1 and 2 may have the adverse impact of increased
erosion of the hillside on the south side of the existing marsh due to
the tidal action.
Mitigation. Increased erosion potential will be minimized by the
plzicement of protective materials such as rock riprap at the base of the
hillside consistent with project design.
Impact. Large amounts of fill material will be required for alternates
3A and 3Band for the construction of the Oakley and Trembath basins.
Mitigation. Alternate 2 will be implemented for reach #1.
Impac~ Further impacts due to soil or fill ccnstraints may be identified
when specific designs have been ccmpleted.
Mitigation. Additional mitigations will be reccmnended, if necessary,
when specific site plans have been completed.
Water: Hydrology, Flood Hazards and Water Quality
Impact. Large volumes of rapidly moving water will have potential
adverse impacts of erosion and structural damage to the newly constructed
· earth channel.
Mitigation. Ectrth embankmen t s for stream channels will be designed
so that peak velocity will have a minimal impact on erodable surfaces.
(County responsibili~y).
Impact. Construction activi t ies during the rainy season may cause
significant degradation of water quality.
Mitigation. Major grading operations will be confined to the dry
season, May to October as much as possible.
Impact. The proposed earth channel and the retention basins will
need regular maintenance to remove d,ebris, trash and sediments.
6
•
RFSOLUTIOO NO. 51-1981
Mitigation. A regular pre-rainy season maintenance program will be
established to remove debris and sediments fran detention basins and stream
cha1nnels.
Impact. Excavation at the p•:riphery of the marsh in Alternates 1
and 2 may create low areas where standing water at low tide could serve
as a breeding area for mosquitos.
Mitigation. For alternates 1 and 2, the marsh area should be excavated
to retain a gentle slope toward the main channel. This mitigation measure
is within the responsibil i ty and jurisdiction of the County or City, the
State Department of Fish and Game, and the Mosquito Abatement District
and not the Flood Control District.
Impa~:_!:.!.... The proposed extension of Lake Alhambra has the potential
impact of an increased safety hazard.
Mitigation. The proposed extension should be fenced or otherwise
secured to reduce accessibility and the associated safety hazards of open
water. This mitigation measure is within the responsibility and jurisdiction
of the County or the City and not th•= Flood Control District.
Impa~~ There is a potential degradation of water quality due to
the close proximity of the proposed Oakley basin and the Kerly Chemical
Plant.
Mitigation. An earth embankment should be constructed between the
proposed basfnand the chemical plant to reduce the potential for degraded
water quality associated with surface runoff at the site. This mitigation
measure is the responsibility of the chemical plant to insure containment
of noxious effluent and not the Flood Control District.
Biota: Vegetation and Wildlife
Impact. The marsh habitat in Reach #1 will be eliminated with the
implementation of alternate 3A or 3B ..
Mitigation. Alternate 2 will be selected for implementation to preserve
significant marsh habitat.
Impact. For alternates l or 2, the freshwater marsh will be significantly
influerced by saline tidal movements which may eventually convert the habitat
to salt marsh.
Mitigation. Further environmental investigations will be canpleted
to determfoe additional potential impacts of converting a freshwater marsh
7
"
RESOUJTION NO. 51-1981
to a salt marsh environment consistent with project design.
Impa~~-Some riparian habitat along East _Antioch Creek will be lost.
or disturbed due to the placement of earth fill to create the detention
basins.
Mitigation. Native riparian habitat will be developed and maintained
within the detention basin areas.
Impact. Mosquito populations may cause problems within the marsh
areas of Reach #3 and with the implenentation of alternates l or 2.
Mitigation. Final site plans will consider additional mitigation
measures recanmended by the Contra Costa Mosquito Abatement District.
Air: Air Quality and Noise
Impact. The short-tenn impact of deteriorated air quality as a result
of air borne dust will occur during excavation of the embankments and detention
basins.
Mi tigati°-._~~ Water will be applied to disturbed earth surfaces to
suppress dust emissions.
NOW, THEREFORE, BE IT RESOLVED that the County Planning Canmission
at its regular meeting held on October 27, 1981 approved and recommends
to the Board of Supervisors the approval of the Final EIR, identified in
