Subject:Adoption of the updated Bay Area and the East Contra Costa County Integrated Regional Water Management Plans,
Countywide. Project No. 7505-6F8239
BACKGROUND:
In 2002, Senate Bill 1672 created the Integrated Regional Water Management (IRWM) Act to encourage local
agencies to work cooperatively to manage local and imported water supplies to improve the quality, quantity, and
reliability.
In November 2002, California voters passed Proposition 50 (Prop 50), “the Water Security, Clean Drinking Water,
Coastal and Beach Protection Act of 2002,” which provides $500,000,000 (CWC §79560-79565) to fund
competitive grants for projects consistent with an adopted IRWM plan. These bond funds were granted in a
statewide application process with a certain amount (40%) guaranteed for areas north of the Tehachapis.
In November 2006, California voters passed Proposition 84 (Prop 84), “the Safe Drinking Water, Water Quality
and Supply, Flood Control, River and Coastal Protection Bond Act,” which provides $1,000,000,000 (PRC
§75001-75130) for IRWM Planning and Implementation. These bond funds were allocated to funding regions
based on population and area to be granted in a competitive process within the nine (9) funding regions. Contra
Costa is in both the Bay Area funding region and the San Joaquin funding region.
In November 2006, California voters passed Proposition 1E (Prop 1E), the Disaster Preparedness and Flood
Prevention Bond Act, which provides $300,000,000 (PRC §5096.800-5096.967) for IRWM Stormwater Flood
Management. Projects to be funded by Prop 1E were required to be “consistent” with (included in) an IRWM plan.
This was a comparative statewide application process.
Below is history and background on the FC District’s involvement in the BAIRWMP and the ECCCIRWMP.
Bay Area Integrated Regional Water Management Plan
In response to the requirement for IRWM plan, the Association of Bay Area Governments (ABAG) utilized its
existing ABAG-CALFED Water Management Subcommittee (subcommittee to the ABAG-CALFED Task Force)
to engage Bay Area water agencies, local government representatives, environmental groups, and the general
public in developing an IRWM plan that identifies, coordinates, and prioritizes projects within the Bay Area. This
began a long-term process of engaging as many water resource agencies as possible to represent the full spectrum
of water resource related interests in the Bay Area.
The outreach took the form of several established Bay Area organizations pulling their members together. Those
agencies without membership in organizations began to collaborate like never before. In general, four “functional
areas” were identified. These four functional areas are listed below along with the organizations that coordinate
their representation in the collaborative efforts related to the Bay Area IRWM planning process.
Water Supply and Water Quality Functional Area (FA): this FA is coordinated by the existing Bay Area
Water Management Agencies Coalition (BAWAC).
1.
Wastewater and Recycled Water: this FA is coordinated by the existing Bay Area Clean Water Agencies
(BACWA).
2.
Flood Protection and Stormwater Management: this FA is coordinated by the Bay Area Flood Protection
Agencies Association (BAFPAA), which was formed in response to the need to coordinate in the IRWM
planning process.
3.
Watershed Management, Habitat Protection, and Restoration: this FA coordinated by the Bay Area
Watershed Network (BAWN), which is coordinated by the San Francisco Estuary Partnership (SFEP) and
under the umbrella of ABAG.
4.
The Bay Area IRWM Plan Coordinating Committee (CC) meets monthly and is the forum in which the
BAIRWMP consensus decisions are made. In this forum, and through subcommittees that worked on specific
issues and tasks, the plan was developed, projects were vetted, grant applications were prepared and the plan
updated.
A website was developed at http://www.bairwmp.org/ to enhance awareness, openness, and communication of the
actions and decisions that the CC was making for the region. Through this website, project proponents can submit
projects, review other projects, and view and download meeting materials and other files.
On March 23, 2004, the Board approved and authorized the Chief Engineer to sign a nonbinding and
nonexclusive Letter of Mutual Understanding (LOMU) that memorialized the intent of the FC District and other
signatories to participate in the development of the BAIRWMP.
On November 13, 2006, the Board ADOPTED the BAIRWMP (2006 Plan) dated November 6, 2006, and
AUTHORIZED the Chief Engineer, or designee, to continue participating in the process of updating, modifying,
and revising the IRWM plan and directing the Chief Engineer to participate in an effort with other Bay Area flood
control agencies to form an association for coordinating input to the IRWM plan.
On April 19, 2010, FC District staff requested authorization through the Transportation, Water, and Infrastructure
Committee to increase its participation level in the Bay Area IRWM planning activities.
As with the 2006 Plan, the 2013 BAIRWMP update was developed through consensus of a large group of
representatives from diverse organizations. Several agencies and organizations in each of the FAs provided the
leadership necessary to secure participation of peer organizations in discussion of the regional plan. A consultant
assisted in the plan update in developing consensus on the Bay Area Region’s goals, strategies, and other
information required by the State Department of Water Resources (DWR) to update the plan. The consultant also
assisted in gathering project information and independently scoring the projects for ranking in the plan. In order to
ensure the transparency of the process, the CC held stakeholder workshops that were open to the public.
The updated BAIRWMP presents nearly 300 projects that will be eligible for Proposition 84 grant funding or
other funding requiring consistency with an IRWM plan in the Bay Area. Many of these projects will provide
water resource benefits to Contra Costa County residents.
The full BAIRWMP can be found at http://www.bairwmp.org/. The plan cover, table of contents, and Executive
Summary are provided as an attachment.
East Contra Costa County Integrated Water Management Plan
The East County Water Management Association (ECWMA) convened in response to the 2002 requirement for
IRWM plans. ECWMA members worked together to produce a “functionally equivalent” IRWM plan and was
accepted by the State. The functionally equivalent (FE) IRWM plan consisted of combining several existing plans
that ECWMA agencies had already created. These were done in a natural, collaborative process in their respective
water resources realms. The Habitat Conservation Plan (HCP) was included in the FE IRWM plan.
Before the IRWM planning effort, the Contra Costa Water Agency (CCWA) was a member of ECWMA. An
amendment changed the membership from the CCWA to the County and added the East Contra Costa County
Habitat Conservancy (Conservancy) to the agreement. The FC District became recognized as a participant in the
IRWM planning effort under the County’s membership due to the fact that the FC District is managed by the
Contra Costa County Public Works Department.
On April 11, 2005, the FC District requested approval to participate in the East Contra Costa County (ECCC)
IRWM planning effort to participate in the cost for professional services to prepare the Prop 50 grant application.
This was the first of several requests for authorization to be involved in the ECCC IRWM planning effort.
The development environment of the ECCCIRWMP and the update was similar to that of the BAIRWMP in that
consultants were hired to assist in the development and update of the ECCCIRWMP and ECWMA agencies work
collaboratively. Unlike the Bay Area, the ECWMA had an MOU that provides organizational structure. The
meetings held to discuss the development of the plan were open to the public. The full ECCCIRWMP can be
found via http://ecccirwm.org/. The Update 2013 Highlights Executive Summary of the ECCCIRWMP is
provided as an attachment.
Funding Received through the IRWM Plan Grants
The following tables depict the funding received to date through the IRWM planning effort.
IRWM Funding Awards Bay Area ECCC
Prop 50 Planning Grants $838,230
Prop 50 Implementation Grants $12,500,000 $12,500,000
Prop 84 Planning Grants $842,556 $901,661
Prop 84 Implementation Grants $52,298,592
Prop 1E Implementation Grants $64,808,000 $12,000,000
Total $131,287,378 $25,401,661
Grand Total $156,689,039
The two Regions (Bay Area and ECCC) overlap. Because of this, three projects in the ECCIRWMP were funded
through two different BAIRWMP Prop 84 implantation grants rounds. This was because the Prop 84 funds are
allocated to 9 specific regions and the ECCC Region overlaps the San Francisco Funding Region, which is
synonymous to the Bay Area IRWM Planning Region. These three projects total $2,205,000 in Prop 84 grant
funding.
Current IRWM grant program status
Due to the drought declaration by the Governor, DWR is administering an accelerated “drought round” to use
$200,000,000 of Prop 84 funds (~42% of remaining Prop 84 funds) for drought relief projects. Draft grant
proposal documents were distributed April 3, 2014, and the anticipated grant proposal due date is tentatively
slated sometime in July 2014. The remaining Prop 84 funds will be put out in a grant round in 2015 and will
likely not be focused on drought relief, though it is too early to tell what the focus of the last Prop 84 round will be.
Commitment and CEQA
The Guidelines and the procedures developed by the DWR and the State Water Resources Control Board mandate
that the IRWM plans be formally adopted, as evidenced by a resolution or other written documentation. The
adoption must be done by the governing bodies of the agencies and organizations that participated in the
development of the IRWM plans and have responsibility for its implementation. Therefore, the Board of
Supervisors, as the Governing Board of the Flood Control and Water Conservation District, must approve the
IRWM plan in order for the FC District’s projects in the IRWM plans to be eligible for grant funding.
The IRWM plans are nonbinding documents. Adoption of the IRWM plans does not entail a direct commitment of
resources. Implementation of each project identified in the IRWM plans will be the responsibility of the project
proponent and any applicable project partners. There is no joint commitment or responsibility by the IRWM plan
participants or adopting agencies to implement any or all of the projects. Furthermore, the project proponents and
applicable project partners have discretionary authority over project design and implementation and may elect not
to implement a project based on changing regional conditions or needs. Upon implementing a project, project
proponents will be responsible for ensuring that all regulatory requirements for the project are met.
The IRWM plans consist of planning studies and basic proposed project information collection that will not result
in the disturbance of any environmental resource. Therefore, the IRWM plans are statutorily exempt from the
California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines §15262. As such, programmatic
environmental analysis under CEQA is not required. Each project ultimately implemented, as a result of this plan,
will require independent CEQA analysis.
Referral History
This item was presented to the Transportation, Water and Infrastructure Committee on April 3, 2014, for referral
to the Board of Supervisors for approval of the adoption of the IRWM plans
CONSEQUENCE OF NEGATIVE ACTION:
If the Board of Supervisors does not adopt the IRWM plans, projects that the FC District proposes for funding
If the Board of Supervisors does not adopt the IRWM plans, projects that the FC District proposes for funding
through IRWM grant programs will not be ineligible for funding. Further, the Upper Sand Creek Detention Basin
has already been awarded $2,000,000 through Proposition 1E, and its funding may be in jeopardy if the
ECCCIRWMP is not adopted.

Update
The East County Water Management Association (ECWMA) will soon begin to update its
Integrated Regional Water Management Plan (IRWMP), originally developed in June 2006.
The Update is being funded by the ECWMA agencies and a planning grant from the
California Department of Water Resources.
An IRWMP is a collaborative effort to manage all aspects of water resources in a region.
IRWMPs cross jurisdictional, watershed, and political boundaries; involve multiple
agencies, stakeholders, individuals, and groups; and attempt to address the issues and
differing perspectives of all the entities involved through mutually beneficial solutions.
The East Contra Costa County IRWMP Update will consist of:
Updating the document to the lastest guidelines and standards, including the
development of new integrated projects
Developing a plan for groundwater and salt/nutrient management in the Pittsburg
Plain Basin
Continuing public outreach, including to disadvantaged communities
More information about IRWMPs may be found at http://www.water.ca.gov/irwm/.

East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 3
Introduction
The East Contra Costa County (ECCC) Integrated Regional Water
Management (IRWM) planning effort is a formal collaborative process
convened to support all aspects of water management. It includes integrated
planning for water supply, water quality, environmental resources, and
flood and stormwater management. The East County Water Management
Association (ECWMA) members have a long history, extending almost two
decades, of cooperation across geographies, political boundaries, and project
types. In this ECCC IRWM Plan Update these participants, referred to here as
ECCC IRWM member agencies, identify projects and actions for the ECCC
region that will create mutually beneficial water management outcomes and
produce projects with multiple benefits.
Starting in late 2011 and during 2012 and 2013 the ECWMA convened a series
of public meetings to work on the DWR Proposition 84 Round 1 Planning
Grant-funded East Contra Costa County IRWM Plan Update.
This IRWM Plan Update articulates the challenges and issues the ECCC
region faces and defines the objectives it hopes to accomplish. The challenges
are significant, as is the opportunity to improve the situation by working
together and with the California Department of Water Resources (DWR). This
plan prominently considers the complexities of managing water supply and
quality, uncertainty and the needs of Disadvantaged Communities, and focuses
on identifying resources to ensure a sustainable future.
To this end the ECCC IRWM member agencies developed a website,
www.eccc-irwm.org to collect and disseminate information, met
with stakeholders, and developed a process to evaluate and prioritize
implementation projects. They also successfully fulfilled the requirements of
the 2011 IRWM planning grant provided in support of the DWR’s effort. The
framework enables the plan to adapt to changing conditions an meet its current
and future water management challenges.

East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 4
ECCC Region
Bounded by the ridge lines of Mount
Diablo to the south and west, and
nestled along the meandering banks
of the complex historic Sacramento-
San Joaquin Delta (Delta) water
system to the north and east, ECCC
is a geographically distinct region.
Its unique footprint both isolates and
incorporates complex urban and Delta
water management issues and brings
with it a unique set of challenges and
opportunities.
The ECCC region is the largest
contiguous land area in Contra Costa
County, and includes much of the
hilly terrain of the Diablo Range.
Home to 300,000+ people and still
growing, its four cities are Antioch,
Brentwood, Oakley, and Pittsburg.
Unincorporated communities include
Bay Point, Bethel Island, Byron,
Discovery Bay, and Knightsen.
In addition to a highly diverse
population, the 350 square miles of
ECCC host a wide range of uses,
including major industrial activities
largely situated along along the
San Joaquin River, agriculture,
and recreation, as well as fragile
habitats and sensitive species. All
are dependent on water. The region’s
water consumers almost entirely
rely on supplies originating from
the western Delta, supplemented
by relatively small quantities of
groundwater and recycled water. The
Contra Costa Water District provides
untreated and treated water to most of
the urban, commercial and industrial
usage within the ECC region and
until 1998 the primary source of
water supply was the Contra Costa
Canal system and Rock Slough. The
Contra Costa Canal system is owned
by the Department of the Interior,
Bureau of Reclamation and was
constructed in 1939.
Residents also benefit from and rely
on critical flood and stormwater
infrastructure, water treatment
facilities, wastewater collection
systems and treatment plants, and
recycled water systems.
The region faces special challenges
as many residents (23 percent) reside
in economically disadvantaged
communities (DAC). These DAC’s
are located largely in areas close
to the Delta and major industry
Figure 2: East Contra Costa County IRWM Region.
East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 5
including power and chemical plants.
Continued water dependent industrial
development near DAC’s may also
result in potential environmental
justice concerns for these residents.
Since most of the region’s water
supply is from the western Delta,
any impacts as well as improvements
to Delta water supply and water
quality directly affect DACs. This
is very different from other IRWM
regions that have access to upstream
water resources (e.g., Sierra Nevada
reservoirs) and pipelines that bypass
the Delta. DACs in these other
locations all receive high-quality
treated water that are not directly
impacted by changes in Delta
water quality.
A lack of community resources can
impact the ability of ECCC IRWM
member agencies to obtain additional
resources for water-related needs.
Yet, even with the recent economic
downturn and the attendant issues
of disproportionate DAC numbers,
community growth is still occurring.
All indications point to an increased
need for water-based infrastructure
and services, now and into the future,
and much of this new infrastructure
created within the ECCC will
benefit DACs.
DWR IRWM Regional Process
In 2009, DWR instituted a Regional
Acceptance Process (RAP) to
evaluate and accept an IRWM region
into its IRWM grant program. Per
these new requirements, the ECCC
region successfully submitted a
RAP application and was fully
recognized by DWR. At a minimum,
a region is defined as a contiguous
geographic area encompassing
the service areas of multiple local
agencies. A region is designed
to maximize the opportunities
to integrate water management
activities; and effectively integrates
water management programs and
projects within a hydrologic region
defined in the California Water
Plan, the Regional Water Quality
Control Board (Water Board) region,
or subdivision or other region
specifically identified by DWR.
Overlap with Bay Area IRWM
Interestingly, the IRWM regional
definition creates some complexity.
As a contiguous geographic area
encompassing multiple member
agency service areas, a portion of
the ECCC region (all of Pittsburg,
Bay Point, and a small portion of
Antioch,) overlaps a section of the
San Francisco Bay Area IRWM
Region Funding Area boundary. The
Bay Area region includes all or part
of nine counties (including part of
Contra Costa and 110 cities), and is
coterminous with the boundary of
the San Francisco Bay Water Board,
Region 2. The ECCC region rests
primarily in the jurisdiction of the
Central Valley Water Board, Region 5
and a portion overlaps with Region 2
jurisdiction in Contra Costa County.
Despite this jurisdictional overlap,
the ECCC region has distinct water
management differences from the
Bay Area and thus was proposed
and accepted as a separate planning
region. Much of the overlap area
within the ECCC region contains
DACs, and their water supply and
quality issues are planned and
managed by ECCC IRWM
member agencies.
As part of its RAP application, the
ECCC IRWM member agencies
identified the East County
Water Management Association
(ECWMA) as the required
Regional Water Management
Group (RWMG). Under the grant
guidelines the RWMG or in this
case the ECWMA, is responsible
for navigating these jurisdictional
complexities, coordinating
with other planning efforts, and
updating and implementing the
ECCC region’s IRWM Plan.
The ECWMA is well suited Figure 3: The East Contra Costa County IRWM Region and neighboring IRWM regions.
East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 6
to this task, having operated as a
collaborative body since 1997.
Members of the ECWMA frequently
attend Bay Area IRWM Coordinating
Committee meetings and Bay Area
IRWM members can attend ECCC
IRWM meetings.
ECCC Water Management
Needs and Issues
The ECCC RWMG, informed by
stakeholder input, identified five
overarching needs to address in the
IRWM Plan Update:
■Water-quality-related regulations
and water supply reliability.
■Restoration and enhancement of
the Delta ecosystem and other
environmental resources.
■Funding for water-related planning
and implementation.
■Stormwater and flood
management.
■Water-related outreach and
equitable distribution of resources
in the region.
The ECCC IRWM region is
almost entirely dependent on Delta
water supply and all or a portion
of the cities and unincorporated
communities are located within the
statutory Delta. This distinction
is important as the Delta is a
physical place with legally defined
boundaries and requirements, which
add to ECCC water management
complexity.
The Contra Costa Water District has
already made substantial investments
in water storage and water quality
by constructing the expanded Los
Vaqueros Reservoir and the Old
and Middle River intakes and
improvements at the Rock Slough
intake. Even so, unreliable surface
water supply, especially in dry
years and when considering future
growth, is a continuing concern as is
regional dependence on Delta water
supplies. Delta Diablo Sanitation
District, Ironhouse Sanitary District,
and the City of Brentwood are all
planning and developing recycled
water projects, which will increase
water supply reliability, and reduce
dependence on Delta supplies.
Issues associated with proposed
future projects such as the Bay Delta
Conservation Plan (BDCP), a fragile
Delta ecosystem, climate change,
and/or potential levee failure are
expected to impact water quality and
water supply reliability within the
ECCC IRWM region. An associated
concern is the ability of the region to
meet future water quality treatment
and discharge regulations.
Present water demand in the region
is driven by a highly diverse
population base with a wide range
of water needs, including urban
and agriculture uses, ecosystem
needs, and recreation. Urban and
agricultural uses make up a majority
of water demand; urban uses account
for about 55% of that demand.
Changes in future water demands
will be driven by rapid increases in
population. By 2035 urban uses are
projected to increase to about two-
thirds of the urban-agricultural water
demand. The ECCC IRWM Plan
includes projects that address this
future demand for water, including
increasing the availability of recycled
water, increasing conservation efforts,
and increasing water supply through
integrated water management.
Closely linked to Delta water
quality and water supply reliability
issues is a need for restoration and
enhancement of the Delta ecosystem
and other environmental resources.
Another set of concerns revolves
around preventing, reducing, and
mitigating for environmental impacts
and restoring historically declining
wetland habitats. Additionally,
water-infrastructure-related projects
within the Delta often require wetland
mitigation and these credits can be
difficult and costly to obtain.
That said, the Region has several
integrated ecosystem efforts already
underway. For example ECCC
IRWM member agencies participated
in the East Contra Costa County
Habitat Conservation Plan/ Natural
Community Conservation Plan. This
plan is intended to provide regional
conservation and development
guidelines to protect natural resources
while improving and streamlining the
permit processes. The East Contra
Figure 4: Los Vaqueros reservoir increases water supply reliability and improves
drinking water quality.
East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 7
Costa Habitat Conservancy is a
member agency and will oversee
implementation. By proactively
addressing the long-term conservation
needs, the Plan strengthens local
control over land use and provides
greater flexibility in meeting other
needs such as housing, transportation,
and economic growth in the area.
One example of the types of projects
that address regional needs is the
Dutch Slough Wetlands Restoration
project. A collaborative effort being
done in partnership with DWR and
others offers an opportunity for
large-scale tidal marsh restoration,
habitat enhancement and open space
preservation in the rapidly urbanizing
area of eastern Contra Costa County
and adjacent to the unlined portion of
the Contra Costa Canal.
These types of integrated projects
will be essential for ECCC in moving
forward. A lack of funding for
planning and implementation because
of slower economic development and
reduced water usage has impacted
revenue, creating insufficient or
variable revenue streams. Additional
funding issues are a result of the
competitive nature of receiving State
and federal funding, limited available
funds, and potential schedule delays
associated with grant funding.
Given that the ECCC IRWM region
includes substantial low-elevation
acreage, is within the drainage of
Mount Diablo, and sits adjacent to
the Delta, both localized flood from
stormwater runoff and regional/
catastrophic flooding due to levee
failure are real and present threats.
Of the past 11 president-declared
natural disasters in the region, all but
one involved storms and flooding.
Climate change is only likely to
increase these risks.
A final set of concerns relates to
water-related outreach within the
area. The region has a substantial (23
percent) DAC population and it is
often difficult to obtain meaningful
feedback on potential improvements
for these communities. One example
is limited access to waterways for
subsistence fishing and recreation.
Climate Change
Climate change will increase
vulnerabilities for nearly all aspects
of water management. The table
below outlines some of the ECCC
climate change considerations.
FACTOR GENERAL OVERVIEW OF VULNERABILITIES
Water Demand Changes in water demand due to temperature, both in quantities and patterns. Peak demands for all
sectors may be greater.
Surface Water Supply Changes in precipitation and temperature in the Sierra Nevada region affect the timing and quantity
of tributary flows. This affects the availability of fresh surface water for the region.
Groundwater Supply Changes in local hydrology could affect natural recharge to the aquifers and the quantity of ground-
water that could be pumped sustainably over the long term. Changed weather patterns can alter
natural recharge of groundwater. Lack of surface water will increase reliance on local groundwater.
Surface Water Quality Rising temperatures increase algal blooms and taste and odor events. A decrease in annual precipi-
tation results in higher concentrations of contaminants during droughts and lower dissolved oxygen
Groundwater Quality Sea-level rise could increase groundwater salinity. Water quality changes in surface water that is
applied as irrigation and that recharges the groundwater could also increase groundwater salinity.
Sea Level ECCC infrastructure below mean sea level and land protected by independently maintained levees
are at risk for increased levee failure and flood damage. Failures could lead to disruption or changes
in water supply reliability, water treatment, and wastewater treatment and disposal.
Flooding Vulnerability to unimproved levees, and increased flood risk with sea-level rise, coupled with
changes to local precipitation and storm intensity. Expected extreme weather events. Increased
flooding could disrupt or change water supply reliability, water treatment, and wastewater treatment
and disposal.
Ecosystem, Habitat and
Restoration
Changed temperature and precipitation can dramatically alter native species habitats. A significant
recreational economy (boating, fishing, biking, and hiking) could be affected by changes to the
ecosystem and wildlife habitat.
Energy Increases in peak energy demands throughout California may decrease power supply reliability. A
decrease in power supply reliability could alter or disrupt water diversions, water treatment, and
wastewater disposal. Region may respond to additional calls for gas generated electricity, creating
higher use patterns of regional facilities, and attend air quality and operational issues.

ECCC IRWM Plan Objectives
With a shared agreement regarding the primary regional water management issues, the ECWMA set its objectives
for the IRWM Plan.
No single objective was determined to be higher priority than the others; however, there are five sets of related
objectives combined to address priority issues. As a result, some objectives address multiple concerns; for example,
maintaining Delta levees supports both flood control and Delta ecosystem protection. The RWMG believes this list of
combined objectives, when implemented, would address the region’s priority water management issues of water supply
and quality, environmental concerns, storm and flood management, outreach and equitable distribution of resources,
and adequate funding to meet regional needs.
The following outlines the IRWM objective categories.
Water Supply Reliability and
Water Quality
■Protect/improve source water
quality
■Carefully monitor proposed
changes to Delta Operations and
how those changes impact water
supply/quality/availability.
■Pursue additional water supply
sources that are less subject to
drought and the availability of
Delta water supplies. For example,
recycled water and desalination
■Increase water conservation and
water use efficiency
■Increase water transfers
■Pursue regional exchanges for
emergencies, ideally using existing
infrastructure
■Enhance understanding of
how groundwater fits into the
water portfolio and investigate
groundwater as a regional source
(e.g., conjunctive use)
■Maintain/improve regional treated
drinking water quality
■Maintain/improve regional
recycled water quality
■Increase understanding of
groundwater quality and potential
threats to groundwater quality
■Limit quantity and improve

Environmental Resources
■Work cooperatively with DWR on
a plan to protect the Contra Costa
Canal while allowing the Dutch
Slough Tidal Restoration Project
to be developed.
■Enhance and restore habitat and
watersheds that contribute to the
Delta and connected waterways
■Minimize impacts to the Delta
ecosystem and other environmental

in treatment and delivery of water,
wastewater, and recycled water
■Develop projects with regional
benefits that are implementable
and competitive for grant funding
■Increase public awareness of
project importance to pass ballot
measures or obtain matching funds
through other means that require
public support
Stormwater and Flood
Management
■Manage local stormwater
■Improve regional flood risk
management
Water-Related Outreach and
Equitable Distribution of Resources
■Collaborate with and involve
economically disadvantaged
communities in the IRWM process
■Increase awareness of water
resources management issues and
projects with the general public
In addition, for each of the identified
objectives addressing a priority issue,
an accompanying set of qualitative or
quantitative metrics were identified.
These represent the targets the region
has identified to meet its requirements
and will be used in monitoring the
IRWM Plan implementation.

Establishing Regional
Project Priorities
ECCC stakeholders were invited
to submit projects for consideration
in the IRWM Plan. The initial
invitation garnered 54 projects
for consideration. These were
then screened, and scored, to
establish priorities.
Scoring was based on the ECCC
region’s needs and objectives and
with consideration of the preferences
outlined by the DWR grant
guidelines. Four categories
of scoring criteria were selected,
with each assigned a weighting
factor representing the relative
importance to the region. The criteria
were then used to score each project
based on merit and ability to help the
region meet its planning priorities.
The categories and relative
weighting were:
1. Regional Objectives (50 percent).
2. IRWM Program Preferences
(30 percent).
3. Statewide Priorities (15 percent).
4. Other factors from IRWM Program
Guidelines (5 percent).
(This category includes additional
DAC and environmental justice
considerations, and contribution of
the project in reducing greenhouse
gas emissions, as compared to
project alternatives.)
The actual scores were highly
dependent on the effort and
understanding of the IRWM process
by project proponents. The RWMG
reviewed the projects with scores as
a group.
ECCC REGION RESOURCE MANAGEMENT STRATEGIES
After identifying the issues and objectives of the ECCC region, the ECWMA considered the strategies and approaches required
to address them. DWR guidelines require the IRWM Plan to document the range of Resource Management Strategy(ies) (RMS)
considered to meet the IRWM objectives and identify which RMSs were incorporated into the IRWM Plan. RMSs are defined as “a
project, program, or policy that helps local agencies and governments manage their water, and related resources.” The list of RMSs
was shared with the ECWMA and stakeholders to consider when developing projects. Of the 33 individual tools described in the
CWP 2009 RMS section, the ECWMA identified 24 with potential for use in meeting the IRWM Plan objectives, plus three new
RMS’s that will be included in CWP 2013 RMSs. The RMSs moved forward for consideration in the ECCC IRWM Plan are listed
alphabetically below.
1. Agricultural Lands Stewardship
2. Agricultural Water Use Efficiency
3. Conjunctive Management & Groundwater Storage
4. Conveyance – Delta
5. Conveyance – Regional/local
6. Desalination
7. Drinking Water Treatment and Distribution
8. Economic Incentives (Loans, Grants, and Water Pricing)
9. Ecosystem Restoration
10. Flood Risk Management
11. Irrigated Land Retirement
12. Land Use
13. Matching Quality to Use
14. Pollution Prevention
15. Recharge Area Protection
16. Recycled Municipal Water
17. Salt and Salinity Management
18. Surface Storage – CALFED
19. Surface Storage – Regional/Local
20. System Reoperation
21. Urban Runoff Management
22. Urban Water Use Efficiency
23. Water Transfers
24. Water-Dependent Recreation
25. Watershed Management
26. Sediment Management

Resource Management Strategies
Diversification Considerations
Each project was evaluated to
determine which RMSs it included
then given a total RMS score.
Projects with a greater number
were considered to contribute
more to regional diversification.
Diversification did not contribute
to the overall project score, but was
a separate criteria for the region to
use in identifying implementation
priorities or proposals for grant
funding.
Implementation Considerations
In addition to the criteria-based scores
and RMS diversification criterion,
project readiness and implementation
considerations were collected for
each project. These included:
■The status and completion date of
planning, design, and construction/
implementation
■Total project cost and total amount
and percent of project funded
■Availability of a project economic
feasibility analysis
Project Review Steps
Project review then followed six
sequential steps:
1. Perform initial screening of
projects for inclusion in the
IRWM Plan.
2. Review benefits claimed by
each project.
3. Integrate and coordinate projects.
4. Evaluate and score projects.
5. Iterate and improve projects.
6. Create a suite of priority projects
that, when implemented, will help
the region to meet its objectives.
Living Document
The final result is an initial list
of IRWM Plan project priorities.
With the Web site and planning
framework established, projects
may be added, removed, or updated
at any time. With a living process,
project proponents and stakeholders
now have a venue to collaborate and
integrate their projects. From time
to time, the RWMG may also initiate
another formal “Call-for-Projects”
to refresh their list or to prepare
for a new funding opportunity.
For instance, the ECCC region
will complete additional planning
efforts under the recently awarded
Proposition 84 DWR Round 2
Planning Grant. Results of this work
may warrant the addition of projects
to the list. Future integrated planning
will continue to be ongoing, open,
transparent, and collaborative.
Benefits and Impacts
By their nature, IRWM plans are
implemented through projects. Those
projects are designed to produce
benefits but may also have impacts
to the region. Benefits and impacts

need to be documented in more detail
to meet the required environmental
compliance laws, such as the
California Environmental Quality
Act and National Environmental
Policy Act, or other local, State, or
Federal permits.
That said, the region has identified
multiple benefits from achieving
its objectives. Key benefits are tied
directly to the five plan objectives.
Benefits
Water Supply and Quality
Projects that improved water quality
or provide reliable water supply are
essential to future viability of all
aspects of the region’s environment,
economy, and culture. Because the
regional supply is tied to the Delta,
projects to mitigate or reduce variable
or negative Delta conditions and
anticipate climate change impacts,
such as drought and extreme weather,
will greatly increase the region’s
resilience and ability to adapt to
changing conditions.
Water supply and quality are linked
as improving and maintaining water
quality contributes to supply (for
humans and the environment) and
is a critical factor in cost. CCWD
has invested approximately $750
million since 1998 to construct the
Los Vaqueros Reservoir and two new
Delta intakes primarily to improve
water quality and for drought
protection. Benefits associated
with water supply projects or water
quality projects (or both) determine
what water may be available for
appropriate uses.
Specific projects proposed to achieve
reliable supply and quality aim to
provide the following benefits:
■Improved ability to adapt to
changing situations caused by the
uncertainty in Delta influences
and future operations and climate
change (such as recycled water and
desalination)
■Reduced per capita consumption
creating benefits such as better
extension of existing and future
infrastructure and supplies
■Increased efficiency of water
within the system (through
regional water sharing and
decreasing leaks and water losses)
■Improved emergency options
(through regional exchanges
for emergencies, ideally using
existing infrastructure to focus
on minimizing the amount of salt
water intrusion into the drinking
water supply, particularly in the
event of a levee failure on
Jersey Island)
■Better understanding and
management of the groundwater
portfolio as a regional source
(e.g., conjunctive use) to reduce
Delta water use and threats to
groundwater quality
■Increased ability to respond to
the regulatory environment and
protect public health by meeting
current and future water quality
requirements for discharges to
the Delta
■Overall improved Delta health
from limiting quantity and
improving quality of stormwater
discharges
Protection, Restoration, and
Enhancement of the Delta Ecosystem
and Other Environmental Resources
Projects focused on ecosystem and
environmental resources recognize
the importance of investments in
watershed health and sustainability.
Specific proposed projects will:
■Provide both local and statewide
benefits by enhancing and restoring
Delta and connected waterways
habitat, as well as conserving
valuable ecological habitat for
state and federally listed special
status species
■Minimize local impacts to the
Delta ecosystem and other
environmental resources by
maintaining Delta water quality
and reducing regional flooding
and road runoff impacts, lowering
salinity in effluent discharges,
minimizing sewer overflows,
curtailing disruptive earth
movements, and decreasing the
amount of water removed from
the Delta
■Contributions to the State’s goals
for addressing climate change, as
outlined in the Global Warming
Solutions Act of 2006
■Improved accessibility to
waterways for subsistence fishing
and recreation and protect public
health by reducing mercury levels
in fish.
Figure 7: Protecting and enhancing
riparian, wetland, and Delta ecosystems
is an important goal of the ECCC
IRWM Plan.
East Contra Costa County Integrated Regional Water Management / Update 2013 Highlights / 12
Stormwater and Flood Management
The benefits of proposed stormwater
and flood management projects are
multiple. Proposed projects will
provide benefits such as:
■Reduced risk and damages
from excess water flows from
storms and floods, resulting in
better economic, social, and
environmental outcomes
■Reduction of impacts to water
quality from excess untreated
and polluted flows
■Improved resiliency and
faster recovery from storm
and flood events
■Increased stormwater and
floodwater protection for areas,
including DACs, that currently
experience flooding and its
related issues
Water-Related Outreach
The ECCC believes engagement with
the community is essential to ongoing
support for IRWM projects. Outreach
educates and promotes actions that
residents and businesses can take
in support of water management
goals. For example, individuals and
businesses can reduce pollutants
entering waterways and practice
water use efficiency. Finally, the
community at large is benefited when
everyone has access to decision
making and the work of the ECCC
is transparent. Some other benefits
of engaging stakeholders include:
■Better project selection by
targeting DACs currently impacted
by annual floods, reduced water
and sewer services, and hazardous
waste sites contributing to
unacceptable contaminant
levels in water
■Improved community health
through improved infrastructure
and water management practices
■Increased awareness of water
resources management issues and
projects by the general public
leading to better decisions by
the public, water managers, and
elected officials
■Increased water quality and
reduced sewer system impacts by
local actions such as appropriate
fat, oils and grease disposal
■Voluntary adoption of renewable
energy sources
■Increased appreciation for the
environment through access to
areas made available for public
enjoyment
Funding for Water-Related Planning
and Implementation
Projects that strive to improve
funding for planning and
implementation fall into several
categories. The ultimate benefit of
this focus is to make sure money
is available to implement projects
delivering the benefits already
described above and to ensure the
public is receiving the best possible
value from its investments. Projects
meeting this objective:
■Increased regional cost efficiencies
in treatment and delivery of water,
wastewater, and recycled water.
For example, projects to reduce
leaks and projects that will reduce
costs of running facilities
■Increased competitiveness for
grants and other funding sources
by leveraging matching funds
■Integrated and increased
opportunities for partnering with
others to get more outcomes for
the same dollar
■Improved the stability of
operations, which ultimately
results in reduced cost. For
example, regularly scheduled
maintenance is less costly than
system failures caused by a lack
of maintenance

Restoration and related projects Tidal marsh restoration projects have a potential to:
• Increase mercury methylation. This happens when projects increase dissolved organic carbon
(DOC) in Delta water. Several studies indicate that methylmercury can damage developing embry-
os and exposure in adults has been linked to increased risk of cardiovascular disease, tremors,
gingivitis, damages to the immune system and other ailments. Humans are primarily exposed by
eating mercury contaminated fish.
• Increase DOC loads in drainage water
• Create temporal impacts from excavation and restoration of marsh area
Groundwater projects If improperly implemented can:
• Damage the aquifer
• Introduce contaminates or allow salinity intrusion
• Increase greenhouse emissions (through energy use for pumping)
Flood and stormwater
management projects
• May reallocate risk from the project location to another area in the watershed by changing flow
patterns and/or increasing contaminants
• May minimize understanding of actual risks from flood by the public
Impacts
Based on the initial project evaluation, anticipated impacts are primarily local, temporary, and associated with
construction. A smaller set of projects may also result in the following types of impacts:
Plan Performance and
Monitoring
As noted earlier, the region’s
objectives included qualitative or
quantitative metrics. These metrics
give the RWMG and its members
a way to determine if the region is
meeting its intent and to assess the
IRWM Plan’s performance. There
may be two levels of monitoring: at
the project level and at the IRWM
Plan level. Levels of monitoring
will be reported and shared with the
RWMG so it can determine how well
the IRWM Plan implementation is
proceeding. The reporting is also
valuable because it will provide
needed signals of implementation
progress that will allow the region
to reconsider what objectives and
approaches may need to be changed,
updated, refined, eliminated, or
supplemented.
Next Steps
This IRWM Plan Update establishes a
strong foundation for future planning
and implementation activities. The
ECCC Water Management Group
will continue to support regional
planning. CCWD will continue to
provide water service to much of the
region. While IRWM plans do not
have regular update schedules, the
RWMG and its members working
with the ECCC Water Management
will use monitoring and be responsive
to regional and statewide needs to
determine the best time to update the
IRWM Plan. An IRWM Plan update
could be triggered by:
■New IRWM Program guidelines
or requirements
■New stakeholders or participants
■A need to change the region’s
boundary, such as contraction,
expansion, or consolidation with
another region
■Significant environmental changes
or other catastrophic events
■Significant updates to local
water planning or local land-use
planning, such as the completion
of planning efforts soon to be
underway associated with the
Proposition 84 DWR Round 2
Planning Grant awarded to the
region in late 2012
■IRWM Plan monitoring results
indicating needed changes
The region plans to follow the
established IRWM Plan for the next
few years. The planning framework
allows for results and outcomes of
future planning efforts, such as the
upcoming Proposition 84 DWR
Round 2 Planning Grant effort,
to be incorporated into an update
of the IRWM Plan. The planning
framework will support requests
for implementation grant funding
in Proposition 84 Round 2 (March
2013) and Round 3 funding requests
and other DWR implementation
grant programs, as appropriate (e.g.,
Proposition 1E). Furthermore,
the RWMG and it members will
reexamine the planning process
and its components, as needed, to
determine if the IRWM Plan or any of
its components (e.g., objectives) need
updating or revising.
Contra Costa County November 17, 2001 Creek and Watershed Symposium
East Contra Costa County
Integrated Regional Water Management Plan
Update
The East County Water Management Association (ECWMA) will soon begin to update its
Integrated Regional Water Management Plan (IRWMP), originally developed in June 2006.
The Update is being funded by the ECWMA agencies and a planning grant from the
California Department of Water Resources.
An IRWMP is a collaborative effort to manage all aspects of water resources in a region.
IRWMPs cross jurisdictional, watershed, and political boundaries; involve multiple
agencies, stakeholders, individuals, and groups; and attempt to address the issues and
differing perspectives of all the entities involved through mutually beneficial solutions.
The East Contra Costa County IRWMP Update will consist of:
Updating the document to the lastest guidelines and standards, including the
development of new integrated projects
Developing a plan for groundwater and salt/nutrient management in the Pittsburg
Plain Basin
Continuing public outreach, including to disadvantaged communities
More information about IRWMPs may be found at http://www.water.ca.gov/irwm/.
If you would like more information about the IRWMP Update or would like to participate in
upcoming public meetings, please contact Marie Valmores at mvalmores@ccwater.com.
