Flood Control Advisory Board
The Flood Control Advisory Board (FCAB) acts in an advisory role to the Board of Directors on
flood control, floodplain management, and related matters. The FCAB reviews planning, operations,
and maintenance of flood control facilities, and recommends an annual budget, which includes a
Five-Year Capital Improvement Program (CIP) to the Board of Directors. The FCAB, in close
coordination with the District staff, reviews program priorities and new policies, and provides their
recommendations to the Board of Directors. The FCAB members also serve the District as
members of the Floodplain Review Board. The Advisory Board consists of seven members, five are
appointed by the Board of Supervisors to five-year terms. In addition to those five members, the
Salt River Project and the City of Phoenix appoint representatives who are ex-officio members of
the FCAB with all rights and privileges granted to other members. Regular FCAB meetings are held
on the 4th Wednesday of each month, and/or the first Wednesday in December. These meetings
begin at 2:00 p.m. in the Flood Control District Administrative Building. Please contact the Flood

Mission/Vision/Pledge
The mission of the Flood Control District of Maricopa County is to provide regional flood hazard
identification, regulation, remediation, and education to Maricopa County residents so that they can
reduce their risks of injury, death, and property damage from flooding, while still enjoying the
natural and beneficial values served by floodplains.
The District’s vision is for the residents of Maricopa County and future generations to have the
maximum level of protection from the effects of flooding through fiscally responsible flood control
actions and multi-use facilities that complement and enhance the beauty of our desert environment.
We pledge to be responsive to our clients in an efficient, effective, and fiscally responsible manner.
We will show personal integrity and professionalism in all our actions, and display continuous
improvement, innovative thinking, and technical expertise. We will be stewards of the environment
and the public’s trust, and we will be concerned about the effects of our actions on not only the
current, but also future generations.

Introduction
1.1

FCD Description and General Context

The Flood Control District was formed on August 3, 1959, following passage of State legislation
empowering counties to set up special districts to provide flood protection. Flood control districts
are political subdivisions of the State and have the same powers, privileges and immunities generally
given to incorporated cities and towns. The District is governed by a Board of Directors who is also
the elected Board of Supervisors for Maricopa County. This Board, in turn, is advised by a seven-

5

member Flood Control Advisory Board. The activities of the District are funded primarily by a flood
control tax levy assessed on real property within Maricopa County and a variety of cost-sharing
arrangements with federal, state, county and local governments. The tax levy rate for the previous
fiscal year (2004/2005) was $0.2119 per $100 of assessed value. The tax levy rate for Fiscal Year
2005/2006 remained constant at $0.2119 per $100.00 of assessed valuation.
The District is organized into seven functional areas arranged in the following divisions:
Administration, Operations & Maintenance, Engineering, Regulatory, Land Management,
Geographic Information Systems, and Planning & Project Management. The Capital Improvement
Program (CIP) serves as the cornerstone of the District's efforts to resolve flooding problems in
Maricopa County. This booklet provides information on the anticipated expenditures for flood
control projects and programs for the next five years, from July 2005 through June 2010.

1.2

The Capital Improvement Program Defined

The Capital Improvement Program (CIP) for the Flood Control District is a revolving Five-Year
Plan that identifies spending for anticipated capital projects. The Plan addresses both modification
and replacement of existing infrastructure as well as the development of new facilities to
accommodate future growth. This Plan also enables the District and its stakeholders to identify
needed capital projects and coordinate financing and construction timing. To increase effectiveness,
the CIP consists of two crucial segments; an administrative process to identify and prioritize future
capital projects (the Prioritization Procedure) and the fiscal plan to provide for the funding of those
projects.
The CIP links the planning and budget activities of the District. It can support not only past policy
decisions by establishing priorities between existing and competing projects, but can also measure
and evaluate the merits of new proposals. Typically, a CIP describes each capital project proposed
for development over the forthcoming five-year period by listing the year that it is to be started, the
cost per year, and, when applicable, the proposed method of cost-sharing. Based on these details
about each project, the District has developed annual cost schedules for capital expenditures. Thus,
the capital improvement program presents both the cost and funding for all the project
requirements for flood control purposes as tempered by current and future financial capability.

1.3

The Difference between the Capital Budget and the CIP

The capital budget represents the first year of the capital improvement plan. The primary difference
between the capital budget and the Capital Improvement Program (CIP) is that the Board of
Directors (BOD) approved capital budget gives the District staff authority to spend funds and
proceed with specific projects. The CIP includes both authorized first-year projects as well as future
projects for which financing has not been secured or authorized. The “out years” of the plan are
thus partially projected and not authorized and hence are subject to change. Every item in the
capital budget must be approved by the BOD and is closely reviewed by the Maricopa County
Office of Management and Budget to ensure that it meets with the fiscal policies of the County. As
a result, the capital budget must be prepared with great care owing to the need for accuracy as well
as consistency with County revenue and expenditure forecasts for the upcoming year(s). The FiveYear CIP is developed and managed by the Planning and Project Management Division for the
Chief Engineer and General Manager, the Flood Control Advisory Board, and the Board of
Directors. Because it is not formally tied to the County’s budgeting process, it can be altered to
reflect future requirements and expectations associated with flood control capital projects.

6

1.4

Undertaking CIP Planning

The CIP process is dynamic and is continually reviewed and adjusted to account for revised forecasts
for major expenditures in the future and adjusted project schedules. The CIP’s five-year perspective
allows projects to be planned and programmed ahead of actual authorization. But the yearly
repetition of the Prioritization Procedure and the CIP process ensures that each project undergoes
several stages of review before it is finally approved and funded. This approach to capital planning is
particularly meaningful in the rapid growth environment of Maricopa County. It ensures that new
facilities will be evaluated within the context of County and municipal land use plans and weighed
against safety and maintenance requirements for existing structures.
Among its many advantages, an effective capital improvement program:
•

Focuses attention on goals, needs, and objectives. It ensures that the District’s capital projects
are consistent with changing community objectives, anticipated growth, and financial capabilities.

•

Requires the scheduling of major investments and reduces the possibility of costly mistakes. It
provides specific project information that assists the Flood Control Advisory Board and the
Board of Directors in making sound budget decisions.

•

Facilitates more efficient administration and management. Focused review of necessary capital
improvements can reduce scheduling problems, conflicting and overlapping projects, and
overemphasis on any single function or geographic area.

•

Promotes cooperation with other jurisdictions. The capital planning process gives all jurisdictions
the opportunity to coordinate location, timing, and financing of related projects.

•

Allows leveraging of FCD funds with other funding sources.

•

Maintains a sound and stable financial program. Dramatic changes in the County’s tax structure
can be avoided when capital projects are planned and implemented over several years.

Flood Control Planning & the CIP
2.1

Overview

The District maintains the Five-Year Capital Improvement Program (CIP) as mandated by State
Statutes and directed by the District's General Policies. The Five-Year CIP includes all costs
associated with the implementation of projects or elements of projects that have been proposed by
federal, state, District or local programs. The selected projects are reviewed through the District’s
Prioritization Procedure that was first approved by the Board of Directors in 1993 and put into
effect for the Fiscal Year 1994/1995. These procedures were amended in 1995 and 1997, and 2001.
The prioritization process solicits project requests from the District's client communities and other
agencies. The process allows comparisons to be made between competing projects to ensure that
CIP expenditures are allocated toward the greatest need.
Following the allocation of funds necessary for maintenance and other mandatory programs, the
District budgets its remaining revenues for capital improvement projects and the related planning
programs. When possible, multi-purpose uses of flood control projects and property are promoted
7

and accommodated. This is possible provided the use does not diminish the flood control project’s
primary purposes. In addition, the project costs to the District and the facility’s maintenance
requirements should not be significantly increased.

2.2

The Planning Process

The Planning Program promotes the District's mission of "...reducing flood risks for the people of
Maricopa County..." by preparing comprehensive regional studies and analyses identifying locations
and property at risk from potential flooding. Following an analysis of flooding problems, alternative
solutions are developed to determine the most cost effective and publicly acceptable project.
Recommended projects are then prioritized for inclusion in the District's CIP. The CIP allocates
resources and provides a timetable for the implementation of individual projects. This process
usually includes the project design, relocation of conflicting facilities, acquisition of property and
construction phases.
The Capital Improvement Program accounts for approximately 65% of the total Flood Control
District annual budget. The District will initiate new projects during the year by pursuing Board of
Directors’ authorization and consummating Inter-Governmental Agreements with other agencies
and municipalities. Activities in the Planning Program include: Area Drainage Master Studies
(ADMSs); Watercourse Master Plans; the Comprehensive Flood Control Program Report; as well as,
project pre-design studies; and the coordination of interagency cooperative projects and agreements.
The District will continue the close historical working relationship it presently enjoys with the other
municipal, county, state and federal agencies involved in furthering the District's mission.
Information on flooding and flood-prone areas is generated through the Area Drainage Master Study
(ADMS) Program. The ADMS program was conceived in 1983 to provide the District with a
proactive and leadership role in developing uniform, comprehensive inventories and models of the
features influencing rainfall-runoff in selected areas. There are forty-eight ADMS areas ranging from
15 to 580 square miles. Area Drainage Master Plans (ADMPs) are then undertaken for each of the
ADMS areas. These plans utilize the information provided by ADMSs and recommend specific,
project-oriented or avoidance solutions for flooding problems. The ADMPs, along with requests
from cities, towns and other agencies, are the primary sources of projects for the CIP.
The ADMS Program supports the planning effort by providing the physical characteristics and
hydrology for a specific area. This Program utilizes a comprehensive watershed perspective, which
is used to identify drainage and flooding problems reported by individual communities. Selected and
approved alternatives to solve these problems are identified through the ADMPs and are
implemented through the CIP. Watercourse Master Plans (WCMP) are similar to ADMPs, except
that a WCMP has more of a focus on the management of a particular river, stream, creek or wash
and its banks and nearby flood zones, while an ADMP focuses on flooding issues over a wider
drainage area.

2.3

Prioritization Procedure

The Prioritization Procedure, employed by the District, was initially implemented for the FY
1994/1995 budget cycle and has been used since that time. It serves as the mechanism for
evaluating new projects for possible inclusion into the CIP. Potential CIP projects are identified
either by local cities, towns and other agencies, or through other District programs. The potential
projects are evaluated on an annual basis for inclusion in the latter years of the CIP.

8

An important aspect of the Prioritization Procedure is the District's cooperation with its client
communities in defining the criteria for project reviews. Tables included in Appendix 1 show the
specific criteria and weights used in identifying project priorities, as determined through workshops
attended by participating agencies and approved by the FCAB. The most recent workshop was held
in May 2003.
The primary benefits of the Prioritization Procedure have been its ability to:
•

Reduce uncertainty by applying District-approved and community-reviewed criteria during the
project review process;

•

Improve fiscal efficiency by requiring concurrent review of all project proposals annually and
timing this review with the District's budget cycle;

•

Eliminate duplication and improve community commitment by focusing planning efforts on
projects approved for pre-design/feasibility analysis; and,

•

Provide a means for reconstructing or reprioritizing the budget and Five-Year CIP with a
minimum of disruption to ongoing activities by using an objective rank ordering system.

The prioritization procedure is accomplished in two major steps. First, all newly proposed projects
are evaluated according to predetermined and weighted criteria by a committee of senior District
staff members. The selected projects may be included in a District-funded and prioritized pre-design
study program, if necessary. Requesting agencies may complete prioritized pre-design studies using
consultants or in-house resources, provided the information produced meets the minimum
requirements of District-sponsored studies. The purpose of the pre-design study program is to
develop more detailed information on potential CIP projects. This includes design and construction
costs, land acquisition requirements, required permits, mitigation and multiple-use potential.
The second step includes the evaluation and prioritization of projects for inclusion in the District's
Five-Year CIP. For projects requiring an Intergovernmental Agreement (IGA), the information
developed in the pre-design study will serve as the basis for negotiations. When ADMPs are
completed, a number of future pre-design studies and CIP project requests are identified. Input
regarding the priorities for projects identified within these plans, will continue to be provided to
local cities, towns and other agencies. When a CIP project has progressed to the stage where the
engineering design, plans and construction specifications are being prepared, its place in the FiveYear CIP is generally maintained. The stability and timeliness of CIP project implementation are
important to the timing of interrelated projects.

2.4

Prioritization Criteria

The Project Evaluation Committee that makes recommendations to the Chief Engineer and
General Manager and the FCAB Program and Budget Committee develops their
recommendations using a system that allocates points to individual projects based on specific
criteria. These criteria include:
•
•
•

Submitting Agency Priority
Master Plan Element
Hydrologic/Hydraulic Significance

9

•
•
•
•
•
•
•
•

Level of Protection
Area Protected
Environmental Quality
Area-Wide Benefits
Total Project Cost
Level of Partner(s) Participation
Operation and Maintenance Costs
Operation and Maintenance Responsibility

The prioritization criteria were developed with the goal of promoting a balanced approach to the
evaluation of proposed projects. The District tries to identify and support flood control and
regional drainage projects that not only provide long-term protection to individuals and property
from flash floods and seasonal flooding, but that contribute to community development, protection
of natural habitat, and maintenance of watercourse flow paths. The District also leverages its
limited resources by entering into joint efforts with other agencies, municipalities or the private
sector to fund flood control projects, and this is reflected in the prioritization criteria. Higher scores
are given to projects that involve cost-sharing partnerships for the construction phase and/or that
involve agreements by other agencies or municipalities to take responsibility for post-construction
operations and maintenance.
Although the relative weighting given to each criterion (total points per category) and the points
actually assigned to each criterion for a given project by an Evaluation Committee member is
somewhat subjective in nature, the evaluation procedure provides a uniform degree of objectivity to
the process. The costs and benefits of the proposed projects are explicitly identified and
documented. Proposed projects can be more easily compared once individual types of benefits and
costs are separately quantified or otherwise evaluated. The inclusion of at least five senior staff
representing different functional responsibilities on the Evaluation Committee further reduces the
degree of subjectivity by ensuring that no one individual’s personal biases excessively influence the
evaluation process.

2.5

Integrating Projects into the Natural & Urban Environment

The District has made an additional commitment to ensuring that new flood control projects not
only protect people and property from flooding threats, but also provide additional benefits. These
benefits can include increased protection for natural habitat, new recreational facilities and open
space, and aesthetically pleasing designs that contribute to the revitalization of urban areas.
Although Maricopa County is located in a largely desert environment, much of the County is
subdivided by canals, rivers, creeks and washes, and these linear attributes are significant features in
defining the physical character of the area. Dams, retention basins, channels and outfalls can also be
found throughout the County, and can have a major beneficial or negative impact on adjacent
neighborhoods and natural areas depending on the design and management of these facilities as
noted by the following projects.
The East Maricopa Floodway (EMF) Mitigation Basins Project is the result of studies done on
the EMF channel as part of the Flood Control District’s Queen Creek/Sonoqui Wash Hydraulic
Master Plan. The EMF was designed and constructed by the Soil Conservation Service, now known
as the Natural Resources Conservation Service (NRCS), to serve as the major regional storm water
outfall for the east valley. The floodway was originally designed to accommodate storm water runoff

10

from then existing rural conditions. As land use transitioned from farmland to development, the
facility is now undersized for the current and future 100-year storm events. The floodway accepts
drainage from an approximately 260 square mile watershed, including major watercourses such as the
Queen Creek Wash and Sonoqui Wash urban storm drain systems, as well as the District’s
Rittenhouse Channel, Guadalupe Channel and drainage from portions of the Superstition Freeway
(US60).
The project consists of two large off-line detention basins known as the Rittenhouse Basin (RBasin)
and the Chandler Heights Basin (CHBasin). Included with the CHBasin will be improvements to
the Queen Creek Wash from downstream of Higley Road to the EMF. The RBasin encompasses
approximately 147 acres, has a 100-year storage volume of 530 acre-feet, and accepts floodwaters
directly from the EMF. The CHBasin, including the Queen Creek Wash improvements
encompasses approximately 233 acres, has a 100-year storage volume of 1,325 acre-feet, and accepts
floodwaters directly from the Queen Creek and Sonoqui Washes.
This project consisting of these two basins is the largest single project undertaken by the District
solely at its cost and without project partners. The 2004 engineer’s estimate for construction of
these two basins, not including landscaping and irrigation improvements around the basin
perimeters, is approximately $42,300,000.00. Because of the physical size of the projects and their
cost, construction of the basins will be accomplished in phases. The RBasin will require two phases
for construction plus a third phase for landscaping and irrigation. The CHBasin will require at least
four phases for construction plus a fifth phase for landscaping and irrigation. As of the end of fiscal
year 2004/2005, the first phase of the CHBasin project was complete, and preparations were
underway for start of construction of the second phase in the fall of 2005. And, the first phase of
the RBasin project was underway, with completion expected in the spring of 2006.
The size and location of the two basins provides a great opportunity for multi-use facilities, rather
than providing only flood protection. Both of the basins are located within the Town of Gilbert and
the District has been working with the Town to develop Intergovernmental Agreements (IGA) that
would allow the Town to obtain easements over the basins and then develop the basins into multiuse regional park facilities for the Town. It is anticipated that the first IGA between the District and
the Town for development of the RBasin could be in place by the end of 2005.
Completion of the two basins over the next five to six years, coupled with the Town’s efforts to
develop the basins into multi-use facilities, will provide the east valley with substantial flood control
benefits while also providing the area with large multi-use regional park facilities.
One of the recommended projects from the Middle New River Watercourse Master Plan is the
reach of New River from Grand Avenue to the Skunk Creek confluence with New River. The
project, a joint effort between the Flood Control District and the City of Peoria, provides flood
protection by channelization and bank protection for approximately two miles of New River.
The channel maintenance roads are intended to become part of a trail system being developed by
the City along several miles of New River. The multi-use trail system is planned to connect the
Arizona Canal Diversion Channel and Skunk Creek trails with the New River trail, extending south
into the City of Glendale.

11

Although a significant amount of mature vegetation within the channel will be protected during
construction, the project required that several acres of vegetation and wildlife habitat on the banks
of the channel be removed. As part of the mitigation requirements for removing the habitat, the
disturbed areas of the channel will be hydroseeded with native trees, shrubs, and grasses. Reestablishing the vegetation is important to provide wildlife habitat and an enjoyable experience for
the planned public uses in the corridor. Construction of the project began in April 2005, and will be
complete in early 2006.
The McMicken Dam Fissure Risk Zone Remediation (FRZR) Project was identified under the
District's Structures Assessment Program Phase I studies for McMicken Dam and
several geotechnical investigations for McMicken Dam. The McMicken Dam FRZR Project is
located north of Olive Avenue and west of the Beardsley Canal within unincorporated Maricopa
County. McMicken Dam provides significant flood protection to the west valley and to Luke Air
Force Base.
McMicken Dam was constructed by the U.S. Army Corps of Engineers (Corps) in 1954 to alleviate
significant flooding in the west valley and to protect Luke Air Force Base. The District rehabilitated
the dam in 1985 based on the results of a geotechnical investigation that determined that significant
ground subsidence had occurred in the area and that the embankment has significant transverse
cracks. Portions of the dam had settled three to four feet. In addition, ground fissures were found
within a quarter of a mile of the south end of the dam. The modifications that were completed in
1985 included reconstruction of the dam to its original design elevation and the installation of a
central geofabric filter to protect the dam from piping failure of the embankment. Additional
geotechnical investigations completed in 2000 indicated that additional ground subsidence has
occurred at the site and that earth fissuring has continued with earth fissures found both upstream
and downstream of McMicken Dam.
The District analyzed 23 alternative designs before selecting a preferred alternative that isolates the
fissure risk zone and its associated 0.6 square mile drainage area from McMicken Dam. The selected
alternative includes a new 1,500 foot long dam segment constructed of soil cement and a basin to
replace the isolated section of McMicken Dam found to be within the fissure risk zone. The basin
will contain flows up to the 500-year storm event or approximately 50 to 70 acre-feet. Final design
of the project was completed by AMEC Earth and Environmental, Inc. and included data collection,
data review, geotechnical investigations, engineering studies, engineering analysis, and permitting for
the project. Additional technical services included aerial survey mapping, biological sciences,
archaeology, and environmental surveys. In addition, because the Maricopa Regional Trail Corridor
is located within the project area, the designer coordinated with a landscape architect to assure the
project was fully compatible with the future design and construction of the trail by others.
Construction began on March 15, 2005 and is schedule to be completed by December of 2005.
Current estimates for the project including planning and design is approximately $4.7 million with
actual cost of construction estimated at $2.9 million. The project is fully funded by the District.

Financial Issues & the CIP
3.1

Balancing Future Revenues & Expenditures – Budgetary Challenges

The District operates on a “pay-as-you-go” basis. This means that the District’s entire capital budget
is funded from current revenues, and that no borrowing takes place to finance capital projects like
dams, channels and levees. The major advantages of this are that the District carries no debt load,
that County taxpayers do not have to pay for interest charges on District structures, and that there is
no need to try to match future debt and interest repayments with future revenues. Since a majority
of the District’s revenues are spent on the CIP and long-term capital expenditures on flood control
protection, taxpayers are in effect investing in the future of the County and their property and safety.
This policy is quite different from that utilized by most government entities, which usually spend
current revenues on operating expenses and debt repayment associated with past capital
expenditures.
Most large government and private sector organizations that plan and construct very large projects
over extended periods of time borrow funds to finance these large projects, and then pay for them
over many years. Because these principal and interest costs can be distributed over many years, and
the necessary funds are obtained from lenders at the beginning of projects, it is relatively easy for
these organizations to plan their long-term capital budgets. The majority of the District’s revenue is
derived from a secondary tax whose revenues can be difficult to predict because tax valuations based
on property values and tax rates can fluctuate from year to year. The rate of growth in urban areas,
and thus total tax revenues, can also have a major impact on total District revenues obtained in any
given year. A strong economy, high levels of residential, commercial and industrial development,
and rising property values will all lead to higher District revenues; conversely a poor economy and
falling property values would lead to reduced tax revenue for the District, for a given tax rate.
Because the District’s capital spending is affected by strong fluctuations in tax revenue, the CIP
must be constantly reviewed and adjusted to reflect the most recent information on current revenues
and expected revenues over the coming years. In the early 1990’s, a weak economy led to lower
District tax revenues, and capital spending had to be reduced to reflect this reality. More recently,
high levels of housing, industrial and commercial development and rising property values have led to
increased needs for flood control projects and increased assessment values. This has necessitated
an expansion in the capital budget to initiate required projects while funds are available. The
members of the Board of Directors, who are also the members of the County Board of Supervisors,
sometimes alter the secondary tax rate to meet overall County fiscal objectives, and this too can have
a major financial impact on the District.

3.2

Revenue Trends and Issues

Funding availability for the CIP is based on estimates that combine anticipated revenues from
numerous sources with the District's anticipated flood control tax revenues. The District’s tax
revenues are a function of the tax rate, which is recommended by the Board of Directors and set
annually by the Board of Supervisors. The Flood Control District tax applies to the assessed real
property valuations, which are also set annually by the County Board of Supervisors. The majority of
the District's Operating and CIP revenues come from the flood control tax that is levied Countywide.
Additional revenue results from the sale or lease of District rights-of-way and reimbursements from
project cost-share partners. Over the past ten years, the inflation-adjusted revenues provided by the
Secondary Tax to the District have slowly increased, however, when the increased size of the
County’s population and increased flood control needs associated with this larger urban area are
taken into account, it is apparent that the District is being asked to do more with less. Most recently
land appreciation has significantly increased the District’s cost for project rights-of-way.

Increased Cost Sharing with Municipalities

Throughout the history of the Flood Control District of Maricopa County, the District has had to
adapt to the evolution of the fiscal, political and institutional environment in which it operates. For
most of the 1970s and 1980s, the District was heavily involved in cost-sharing partnerships with the
Federal and State governments, initiating and participating in flood control projects that were
planned and funded in large part by higher levels of government. With the virtual end of large-scale
participation in regional flood control activities by the Federal Government and the State, the
District was left in the position of being the primary source of technical expertise and financial
resources for flood control in Maricopa County. As a result, the District must deal with a wide
range of regional flood control challenges with a limited budget.
The District has adopted a number of strategies to address regional flood control problems while
minimizing financial requirements. Under the direction of the Board of Directors and Flood
Control Advisory Board, District staff have made a concerted effort to make maximum use of every
dollar spent. A strategy used to obtain the “most bang for the buck” has been to leverage District
capital program expenditures with contributions from municipalities and other agencies. One of the
selection criteria for potential projects is the degree to which the projects will be paid for by other
government entities; if a higher level of cost sharing can be negotiated; the projects are given a
higher priority ranking by the District. A District goal is that it should only have to pay for half to
two-thirds of the design and construction costs and that a municipality or other agency will be
responsible for the remainder of those costs and for future operations and maintenance.
Reviewing the total dollar amount of reimbursements provided by the District’s partners during the
1980s, it is clearly evident that the trend is towards rising reimbursements. While total
reimbursements were only approximately $2.4 million in FY 1992/93, they had grown to
approximately $7 million by FY 1996/97, to more than $25 million forecasted for FY 2005/2006.
Similarly, an examination of reimbursements as a percentage of total capital program expenditures
indicates that the long-term trend is towards higher levels of cost-sharing. While in FY 1992/93 less
than 10% of the District’s capital program was funded by reimbursements from municipalities and
other agencies, in FY 2003/2004 approximately one-third of the capital program budget was
provided by other government entities. The trend during the last few years reflects that the costsharing revenue has leveled off at 30-35% of the annual CIP.

15

Expenditures made by the District to operate and maintain flood control structures and adjacent
property are substantial; in FY 04/05 these operations and maintenance (O&M) costs were
approximately $5.5 million, or about 18% of the total budget. One of the most important strategies
of the District in recent years in terms of minimizing future expenditures and of providing the most
regional flood control protection at the least cost has been to enter into partnerships on projects
where the District is responsible only for capital costs and not for O&M costs. To date, the District
has been very successful in negotiating cost-sharing agreements in which the District is absolved of
any responsibility for future maintenance or operations. A large number of new projects involve
intergovernmental agreements (IGAs) that restrict District involvement to only initial capital costs.
More simply put, by following a policy of not assuming O&M on most new projects since the early
1990s, the District will spend a smaller percentage of its budget on O&M annually. The District will
continue to operate and maintain 22 dams, the Arizona Canal Diversion Channel, and most of its
older projects.

3.4

The CIP: Implementing FCD Financial Strategies and Priorities

The District’s capital spending utilizes the majority of the District’s overall revenues, and the
District’s capital spending is directed by the Five-Year CIP. As a result, the Five-Year CIP must
incorporate the District’s strategies and priorities, and facilitate the achievement of the District’s
mission and objectives. Among the District strategies/priorities that are reflected in planned
expenditures included in the Five Year CIP are:
•

A continued emphasis on cost-sharing and partnerships so that the District is best able to
leverage its limited financial resources into the most long-term flood control protection possible
throughout the County. Partner contributions should be concurrent with District expenditures.

•

A preference for partnerships in which the other partners (e.g. municipalities, agencies) assume
full responsibility for operations and maintenance activities once the project has been completed.

•

A continuing commitment to balance expenditures between newly-developing areas on the
fringe of the urban metropolis, and existing older communities where retrofitting, repairs and
project improvements are needed.

•

A commitment to avoid the construction of new conventional hard structures when nonstructural approaches such as flood plain delineation and management, natural watercourse
improvements, and/or minor improvements to natural drainage patterns can be used just as
effectively from an economic perspective to protect lives and property.

•

A focus on minimizing project costs and streamlining the contract tendering and management
processes using information systems that track project progress and analyze engineering, land,
and construction costs.

•

Use of District-developed hydrological and flood control planning information by other entities
so that private development infrastructure is built to District standards.

How to Use This Document
Included in this document are narrative descriptions and location maps for the four dozen projects
that the Flood Control District of Maricopa County proposes to implement during the next five

16

years (FY 2005/2006 through FY 2009/2010) and summaries of the CIP budget that show
projected expenditures by “Area” (groupings of projects) and by “Project” (individual facilities and
systems). Table 3 provides a summary of the results of the FY 2005/2006 Prioritization Procedure.
Included in these tables are each of the projects recommended for CIP consideration through
previous prioritization procedures. The Prioritization Procedure section includes a description of
the procedures and criteria used in evaluating potential CIP projects.
The figures in both tables are shown in thousands of dollars (i.e. 10 equals $10,000), for ease of
display, and are shown by fiscal year for each of the five years. A "Total" column sums all of the
expenditures, by project, proposed during the five-year period. It is important to note that although
most of the projects are scheduled to be completed in five years, those identified with an asterisk (*)
will be continued beyond the five-year period. Possible reasons include: availability of funding; status
of design or construction plans; or incompatible schedules of other related activities. Also included
in the tables are columns showing supervisor districts and the municipality where the project is
located.
A description and details are provided for every project name and associated project control number
appearing in the Five-Year CIP. Each project can thus be found in this document. Every project
description includes basic information such as project name, project control number, the
municipality or municipalities in which the project is located, partners involved with the design,
administration, construction and/or funding of the project, anticipated beneficial results of the
project, and the timing and cost of the project. The projects are listed in order of their project
control numbers, or PCNs. An alphabetical list of projects is also provided at the beginning of this
document that provides the PCN and page number for each project. Included with each project
description is the name of the responsible project manager and information on how they can be
contacted. The project managers may also be contacted through the general District switchboard at
(602)506-1501.
In some cases, such as those in which the planning and design work is complete and construction is
already underway, the scope and cost of the project are almost entirely known. In others, a project
might only be in the planning and design stage, and the exact physical design, geographical location,
and total cost of the project are still unknown. As a result, the further along the project is, the more
likely the project description is to be a complete and dependable guide to the specifics of the project.
It should be noted that projects still in the early stages of the development process will be subject to
change, and that significant increases or decreases in project costs do occur well into the design
stage. In some cases District projects can be combined with other projects undertaken by ADOT or
MCDOT, leading to major reductions in project costs, while in others, unforeseen land acquisition
or project engineering costs can greatly increase project costs.

Project Manager:

Don Rerick, P.E.

The project provides a storm drain collection system and four retention basins located along the Highline Canal that
will capture and convey the 10-year storm event within the Town and east of Avenida Del Yaqui. Runoff from within
the Town results in flooding of low-lying houses and collects along the Highline Canal where it eventually overtops the
canal and causes damage to downstream properties within Tempe. Three of the basins are located within the Town,
and one along the east side of the canal is in Tempe. The three basins within the Town have been landscaped and now
serve as Town parks. The basin in Tempe, because of its small size and its depth has been landscaped and fenced. The
project costs for design, right-of-way acquisition, utility relocation, environmental studies and construction of the
project were less than $7 million. Construction of the project has been completed with the exception of a future pump
station that will be designed and constructed by the City of Tempe as part of this project. The District will share in the

The Laveen Area Conveyance Channel (LACC) is a public and private partnership that improved the Maricopa Drain
into a regional flood control facility. This project, consisted of 5.8 miles of conveyance channel and a detention basin at
43rd Ave. and Southern Ave., that reduced flooding in the Laveen area. The channel and basin will also function as
park facilities for the City. Construction of the channel commenced in August 2003 and was completed in September
2004. The irrigation and landscaping for the channel and basin is under construction and will be completed in Fall
2005.

The 23rd Avenue/Roeser Road Detention Basin & Storm Drain is identified as an element for regional flood control
infrastructure as defined by the recommended plan for the South Phoenix / Laveen Drainage Improvement Project,
The Preliminary Design Report was completed in July 1997. A proposed 10-acre detention basin, to be located on the
northeast corner of 23rd Avenue and Roeser Road, will intercept flows from the north and the east. The Basin will be
designed to intercept flows from a 100-year storm and will then discharge approximately 40cfs to a storm drain that will
be constructed along Roeser Road. This storm drain will then discharge to a new storm drain to be constructed along
27th Avenue from Roeser Road to Broadway Road. An existing 108-inch storm drain will then convey the flow from
Broadway Road to the Salt River.
The project is currently in the 60% design stage. The 10-acre basin at 23rd Ave and Roeser Rd has been acquired and
design will be completed in FY 2006. Construction is scheduled for FY 2006 and 2007. The City of Phoenix is the lead
project agency.

Residents in the South Phoenix area have been flooded during relatively minor storm events, including those considered
to be less than 10-year storms. The South Phoenix Drainage Improvement Project will provide protection from a 100year flood event to residences and developing farmland within the City of Phoenix. The project will be built in phases
to maximize the potential for cost sharing with other agencies. The 100-year protection will be in place once all of the
phases are completed. The South Phoenix Detention Basins are located at the intersections of 43rd Avenue and
Baseline Road, and 27th Avenue and South Mountain Avenue. Preliminary designs have been prepared for each of the
detention basins. The Basins were submitted by the City of Phoenix in the 1999 Prioritization Procedure, and approved
by the Prioritization Committee. The proposed schedule assumes that the City of Phoenix is able to appropriate funds
for this project. The goal is for the District to contribute approximately 50% of the project cost of the South Phoenix
Drainage Improvements. The District acquired the basin sites when Baseline Road was widened and the Baseline Road
Storm Drain was constructed.

The Tres Rios Project is a federal project under the auspices of the U.S. Army Corps of Engineers. The local sponsor is
the City of Phoenix. The project is located along the Salt and Gila Rivers from about 83rd Avenue to the Agua Fria
River. The project consists of the restoration of habitat within and along the river, including constructed wetlands,
open water marshes, and riparian corridors. Along the north bank of the river from approximately 105th Avenue to the
Agua Fria River will be constructed a flood control levee to remove property and homes along the river from the Gila
and Salt River floodplain. In accordance with the approved project Resolution and IGA, the District's participation
consists of design review and coordination, funding $2,000,000 in cash toward construction of the levee, operation and
maintenance of the levee, and contribution of District owned land required for the project. The Corps has completed
the design of phase 1A of the levee, and construction by the Corps is scheduled to begin in FY 2005/2006. Design on
the second phase 1B of the levee continues with construction not yet scheduled.

White Tanks Flood Retarding Structure No. 4 (White Tanks FRS No. 4), operated and maintained by the District,
requires corrective action to bring the structure into compliance with dam safety standards and requirements. An outlet
channel from White Tanks FRS No. 4 to the Gila River is required. In addition, an outlet channel from White Tanks
FRS No. 3 to No. 4 is required (reference White Tanks #3 Outlet Channel for this related project).
The District has completed Phase I Assessments for White Tanks FRS #4. The Arizona Department of Water
Resources (state agency with regulatory authority) has classified the dam as having safety deficiencies that require
corrective action. These deficiencies include transverse cracking of the embankment, left spillway adequacy, and
unprotected corrugated metal pipe outlets. The Natural Resources Conservation Service (NRCS) has also identified
these same deficiencies that require corrective action. The District submitted an Application to NRCS for federal
funding assistance under Public Law 106-472 (Small Watershed Amendment) in May 2004. The District has initiated
the alternatives evaluation and pre-design efforts under the operating budget in FY 2004-05 and will complete the
alternatives analysis in FY 2006-07. The study will result in a recommended alternative for the channels and
rehabilitation of the dam.

McMicken Dam was constructed by the U.S. Army Corps of Engineers (Corps) in 1954 to alleviate significant flooding
in the west valley and to protect Luke Air Force Base. The District rehabilitated the dam in 1985. A geotechnical
investigation had determined that significant ground subsidence had occurred in the area and that the embankment has
significant transverse cracks. Portions of the dam have settled three to four feet. In addition, ground fissures were
found within a quarter of a mile of the south end of the dam. The modifications that were completed in 1985 included
reconstruction of the dam to its original design elevation and the installation of a central geofabric filter to protect the
dam from piping failure of the embankment. The dam provides significant flood protection to the west valley and to
Luke Air Force Base.
The District initiated a Structures Assessment Program Phase I studies for McMicken Dam, and several Geotechnical
Investigations for McMicken Dam. The results of a geotechnical study indicate that ground subsidence has continued
to occur at the site and that earth fissures have been found both upstream and downstream of McMicken Dam. The
District believes the ground subsidence and presence of earth fissures in close proximity to the dam poses a risk to dam
safety that necessitates corrective action in a timely manner. The District initiated an alternatives analysis and design
for mitigation of the fissures. The selected alternative which consists of a new dam segment that removes a section of
McMicken Dam from a fissure risk zone and includes a new basin is currently under construction.

Buckeye FRS No. 1 is the western most dam of the series of three flood control dams that were all designed and built
by the Soil Conservation Service (now the Natural Resources Conservation Service – NRCS) between 1973 and 1975.
The dam is located along the southern slopes of the White Tank Mountains and parallels the north side of Interstate 10
for 7.1 miles west to the Hassayampa River. The dam is operated and maintained by the Flood Control District of
Maricopa County (District) and is regulated under the jurisdiction of the Arizona Department of Water Resources
(ADWR).
Since the dam’s original construction, the dam has experienced considerable transverse cracking. ADWR has identified
the transverse cracking in Buckeye FRS No.1 as a dam safety deficiency that must be corrected. The District has
completed Phase I Assessments of the dam and has requested federal cost share assistance under Public Law 106-472,
The Small Watershed Amendment, with NRCS for a rehabilitation project to address the dam safety concerns and to
maintain flood control benefits to downstream properties for the next 100 years. Alternatives may include a modified
dam, floodways, or basins, which will provide a minimum of 100-year flood protection.
Buckeye FRS No. 1 has been identified as a major component of the proposed Maricopa Regional Trail Phase 3 Master
Plan. Project planning will include the coordination of any interested stakeholders for the incorporation of a
recreational federal cost share component to the rehabilitation project.

Spook Hill FRS is a structural plan element of a Watershed Work Plan, prepared by the Natural Resources Conservation
Service (NRCS; formerly Soil Conservation Service) in January 1963, for the Buckhorn-Mesa Watershed Project located in
Maricopa and Pinal Counties, Arizona. Spook Hill FRS was designed to impound floodwaters for a 100-year flood
event and direct flows in excess of the 100-year flood event through an emergency spillway. The Loop 202L segment of
the freeway, as currently being designed, will pass over Power Road, the Central Arizona Project (CAP) Canal, and the
north end of Spook Hill FRS. The freeway will be located adjacent to and within the flood pool of Spook Hill FRS.
The freeway will again pass over the Spook Hill FRS and CAP Canal, at the south end of the Spook Hill FRS and
transition to become a depressed freeway at University Drive. ADOT will modify the Spook Hill FRS to accommodate
the construction of the freeway.

The Spook Hill Area Drainage Master Plan updated and expanded the existing Spook Hill Area Drainage Master Study
conducted in 1987. Since the 1987 study, much of the watershed has been developed, additional drainage infrastructure
now exists, and man-made changes have occurred in the watershed. The Spook Hill area in east Mesa currently does
not have the flood control and drainage facilities in place to handle its regional flood problems. The approximate
watershed area is 16 square miles. The study identified current area flooding problems and produced a recommended
alternative to resolve the current flooding problems. A preferred alternative has been chosen and adopted by the City
and County officials. The recommended plan is a series of underground pipes, open channels, and offline detention
basins to reduce the flooding in the area and provide a 100-year level of protection. The total cost for the design and
construction of the plan is estimated at $32 million. An intergovernmental agreement (IGA) has been drafted and
approved between the City of Mesa and the District for the purchase of lands necessary for the detention basins.
Other IGAs are in place for design of the McDowell Road Storm Drain as well as the Culver- Hawes Basin and
Hermosa Vista Storm Drain. Future IGA’s will be drafted and negotiated with the City for the design and construction
of the other elements of the recommended plan. Much of Mesa’s funding will be out of their City bond programs.

The Elliot Basin & Channel is a project that is identified in the East Mesa Area Drainage Master Plan. The East Mesa
ADMP identifies drainage problems and develops solutions for a storm water collection and basin system for eastern
Maricopa County including portions of the City of Mesa, the Town of Gilbert, the Town of Queen Creek, and
unincorporated Maricopa County. The Elliot Road Channel component of the project extends along Elliot Road from
the 104th Street alignment to the East Maricopa Floodway. A large diameter storm drain collects storm flow from the
Siphon Draw Wash and extends west along Elliot Road, day-lighting west of Ellsworth Road into natural washes.
These improvements have been constructed. The remaining features are a channel, extending from Ellsworth Road to
the future San Tan Freeway, and a channel along the Crismon Road Alignment, from Paloma Avenue to Elliot Road.
Mesa, MCDOT and the District have cooperated on the completed features and will share in the costs of the
remaining features. Construction is scheduled for completion in Summer 2005.

Design and construction of the Ellsworth Channel will be included in MCDOT’s Ellsworth Road - Germann to
Baseline project (Project). Ellsworth Channel was identified as a high priority component of the regional flood plan in
the East Mesa Area Drainage Master Plan. MCDOT developed a Design Concept Report (DCR) for the Project, which
provided a preliminary design for the flood control features. The Ellsworth Channel will begin south of Pecos and
Ellsworth roads and convey the future 100-year flood to the East Maricopa Floodway, and alleviate significant flooding
problems for the upgraded Ellsworth Road. MCDOT is the lead agency for the Project. IGA 2000A002 authorizes
design and construction of the Ellsworth Channel, and identifies a cost share of 50 percent FCD, 40 percent City of
Mesa, and 10 percent MCDOT, for the channel related features of the project. Bids were opened for the project on
June 1, 2005 and construction is expected to begin in Summer 2005.

The District completed the Glendale/Peoria Area Drainage Master Plan Update Study (G/P ADMP) in May 2001. The
Study made several recommendations for regional drainage infrastructure to provide 100-year protection for the G/P
ADMP watershed. The Rose Garden Lane Channel is a high priority recommendation of the G/P ADMP and ranks as
a high priority flood control project for the City of Peoria. The City Council of Peoria adopted the recommendations of
the G/P ADMP in May 2001, and the Board of Directors for the District adopted the G/P ADMP recommendations
in December 2001(Resolution FCD 2001R012).
The channel is an open channel along the north side of Rose Garden Lane and will provide 100-year level of protection,
though a lesser level of protection may be appropriate if agreed to by Peoria and the District. The channel will benefit
an area between approximately Lake Pleasant Road and the Agua Fria River, south of Rose Garden Lane. The channel
will accept flows, which currently flow over Rose Garden Lane and overflow the Beardsley Channel, and divert them to
the Agua Fria River. An intergovernmental agreement between the District and the City of Peoria is in place for the
design and an IGA is negotiation that will define the project partners' responsibilities for construction, construction
management and operations and maintenance.
The project is currently in the 30% design stage. An alternative analysis will be done to investigate alternative outfall
locations within the Agua Fria River due to nuisance flow and flooding issues on Rose Garden Lane within the river
boundaries. Design will be completed FY 2006 and construction is scheduled for FY 2006 and FY 2007.

The District and the Cities of Glendale and Peoria developed the Glendale/Peoria ADMP Update study to identify
existing and future drainage and flooding problems in the watershed, and to develop cost-effective solutions to alleviate
those problems. The ADMP Update study assisted the Cities and the District in the prioritization and development of
drainage infrastructure needs for the area, and included preliminary design plans for a recommended 9-Phase
Improvement Projects program. The Improvement Projects program consists of channel improvements, detention
basins, open channel conveyances, storm drains, and other storm water collection and disposal systems that provide
100-year protection for the 85-square mile watershed. The estimated total cost for the multi-year Improvement
Projects program is $34.3 million with several potential cost-sharing partners, including the City of Peoria as the
primary partner. The Peoria City Council adopted the recommendations of the ADMP Update study, and submitted
Phases 1, 2, and part of 3 to the District during the FY 01/02 Prioritization Procedure. Currently, IGAs are in place
between the District and the City of Peoria for the design of the 83rd Avenue and Pinnacle Peak Road Drainage
Improvements Project and the Rose Garden Lane Channel Project. Future projects were favorably evaluated and the
District’s 5-year CIP budget includes this funding to begin implementation of the various phases dependent upon
priorities and cost.

White Tanks FRS No.3 is ranked first in the nation by Natural Resources Conservation Service (NRCS) that requires rehabilitation
under their dam rehabilitation priority ranking process. The District and NRCS have proceeded with the project under “The Small
Watershed Rehabilitation Amendment” (Public Law 106-472), which authorizes NRCS to assist watershed project sponsors with
rehabilitation of aging dams on a 65% federal, 35% local cost share basis. NRCS is currently providing technical assistance (NRCS
staff assistance) under this program for the project. The District and NRCS completed the final work plan and environmental
assessment in 2004. The District signed an IGA with NRCS, which defines District and NRCS activities and cost share
responsibilities for the project in early FY 2004-2005.
In FY 2003-2004 under Contract FCD 2003C014, alternatives were evaluated that would maintain the same flood protection as the
existing dam. The project alternative selected was a dam modification. The dam modification design, under contract FCD
2003C055, has been completed for Phase I of the project. Phase II of the design will be completed in 2005 under the same contract.
The District will initiate construction of Phase I in 2005.
It is intended that White Tanks FRS No.3 Rehabilitation Project will be constructed in three phases as follows:
Phase I : White Tanks FRS No.3 Rehabilitation Phase I
Phase II : White Tanks FRS No.3 Rehabilitation Phase II
Phase III: White Tanks FRS No.3 North Inlet Channel Improvements
While the IGA describes the Project in its entirety, the specific federal funding included in the IGA is for Phase I only of the
Project. The federal cost share for the Project to date is $9 million. Federal funds have been allocated in this amount under federal
fiscal years 2004 and 2005. The Agreement was signed by both the District’s Board of Directors and NRCS in 2004. It is intended
that cost sharing of Phase II and Phase III will be supplements to the IGA; however, federal funding of Phase II and III will be
subject to approval of federal appropriations and Project allocations on a fiscal year basis.

Bullard Wash is included within the Loop 303 Corridor/White Tanks Area Drainage Master Plan (ADMP), which
recommends improvements be made to the wash. Phase I of the Bullard Wash Improvements Project, from the Gila
River to Lower Buckeye Road, was constructed as a previous District/City of Goodyear project. Phase II includes an
earthen/greenbelt channel along the Bullard Wash alignment from Lower Buckeye Road to McDowell Road. A future
phase may include a diversion channel will take high storm flows from Bullard Wash at McDowell Road through the
detention basins north of I-10 and west of Dysart Road, with an outlet to the Agua Fria River. Landscaping, fencing
and other multi-use facilities are anticipated along the channel alignment and within the basins.
The project will channelize the floodplain north of the Phoenix-Goodyear Airport. It will reduce the floodplain
width and protect the Phoenix-Goodyear Airport and nearby development from flooding. For the area north of I-10,
the project will collect and convey storm-water currently draining by sheet flow to Bullard Wash. This storm water will
otherwise collect in streets, businesses, farm fields, and residential areas. Design of Phase II is complete. An
intergovernmental agreement with the City will be required for construction of the project.

The study consisted of an area drainage master plan to determine guidelines for stormwater management and structural
mitigation measures for flooding in the White Tanks area. The study included analysis of approximately 208 square
miles of watershed, which extends from Grand Avenue south to the Gila Rivers, and from the White Tank Mountains
east to the Agua Fria River. The study identified drainage problems, updated the existing hydrology due to development
and new hydrologic methodology, developed cost effective solutions for a stormwater collection and conveyance
system and identified a preferred outfall alternative. The future design and construction phase will involve the
implementation of solutions to flooding that are identified the planning phases and remedial actions have been
specified. Total expenditures proposed for the CIP are now estimated at $400 million for identified projects, which
includes the costs for the Loop 303 Regional Drainage Channel and Basins.

The project will channelize Queen Creek Wash from Hawes Road northwesterly to Power Road for a distance of
approximately two and one half miles. Based on the Flood Insurance Study on Queen Creek Wash, there are areas of
significant breakouts particularly along the north bank of this reach of the wash. The most feasible solution for
preventing the breakouts from occurring along Queen Creek Wash in this area is to increase the cross section (capacity)
of the wash to contain the 100-year flows. This project consists of channel construction, landscaping and construction
of the Sossaman Road Bridge across the wash.
The Town of Queen Creek is the lead agency for design, rights-of-way acquisition, utility relocation, construction,
construction management, and will own, operate and maintain the completed project. The District shall review and
approve the design and the construction documents prior to bid. The total cost of the project is estimated at $6.0
million with District’s contribution limited to $2.42 million. The design was completed in FY 2003, and construction is
underway with substantial completion achieved in early calendar year 2005. Winter storms then caused damage to the
nearly completed project. The Town and the District are working to develop a repair plan to be implemented and then
complete and close out the project in FY 2005/2006.

The project design includes channelization of Sonoqui Wash from Queen Creek Wash just west of Higley Road to
Chandler Heights Road. The existing wash does not contain 100-yr flows and is subject to flooding adjacent property
owners. The proposed channel will be designed to collect and convey the 100-yr flow. The current floodplain
encompasses approximately 800 acres of land. After completion of the project, the floodplain will be confined to the
channel located within a 200’ wide strip of land, and the remaining land can be removed from the floodplain. This is a
joint project between the District, and the Towns of Gilbert and Queen Creek. The District will be the lead agency for
the design of the project including bank improvements, major roadway crossings, channel stabilization, and landscape
and trail improvements. The District will construct the channel and the Towns will be required to implement the
proposed Landscaping of the channel at their own expense. The Towns will own, operate and maintain their portions
of the channel. The adjacent developers, as per their development agreement with the Towns, will dedicate most of the
land required for construction of the channel.

The Queen Creek Road Basin was identified as one element of the recommended plan of the Higley ADMP. The basin
would serve as an off-line basin, in order to alleviate the flooding problems along the eastern boundary of the
Consolidated Canal; as well as flooding to the west caused by possible overtopping of the canal from runoff generated
within the study area. The basin will retain approximately 204 ac-feet of storage volume for up to a 100-yr frequency
storm event. The City’s Parks Department is interested in developing this basin as a regional park and also will own,
operate and maintain the basin once constructed. The City is the lead for design and construction.

The purpose of the Adobe Dam-Desert Hills ADMP was to develop a Recommended Alternative to mitigate identified
drainage flooding and erosion hazards in the study area. The recommended alternative comprised a combination of
both structural and nonstructural components resulting from a rigorous analysis and comparative evaluation of multiple
alternative measures.
The recommended alternative for this area has many structural features that are within different segments of the study
area. Some of the structural alternatives include construction of a channel upstream of Pinnacle Peak Road to a point
where Skunk Creel flows out of the landfill area; construction of new levees immediately downstream and upstream of
the CAP as well as upstream and downstream of New River Road Bridge; construction of basin, channel, and culverts
for the Desert Lake wash; construction of bridges on Desert Hills and New River Roads; construction of grade control
and erosion protection on Skunk and Cline Creek; and re-alignment of roadways. The non-structural elements of the
recommended alternative include; floodplain delineations, flood response plan, development guidelines, and voluntary
participation in the Floodprone Properties Acquisition Program. These features of the recommended plan may be
implemented individually or collectively in the future based on scheduling, funding, and cost sharing.

The proposed channel improvement will bridge the gap between the south edge of the existing Skunk Creek Channel
and the drop structure upstream of the Pinnacle Peak Bridge. Currently, the 100-year design floodwaters break over the
levee and travels across Pinnacle Peak Road into the Paseo Highlands Park on the south side. The channel
improvement project will eliminate the split flow over the existing levee and also any potential flooding on the west
bank of the Skunk Creek Channel.
The Adobe Dam-Desert Hills Area Drainage Master Plan also identifies this project as an element of the recommended
alternative. The proposed project will guide and direct the 100-year design flow into the drop structure upstream of the
Pinnacle Peak Bridge without any further breakouts. Numerous residential and a few commercial properties on the
west side of the Skunk Creek upstream of the bridge will be protected from the 100-year design storm. The District
and the City will share the design and construction of this proposed channel.

The study consisted of an area drainage master plan to determine guidelines for stormwater management and structural
mitigation measures for flooding in the Durango Study area. The study included analysis of approximately 68 square
miles of watershed, which extends from I-10 south to the Salt/Gila Rivers, and from approximately 27th Avenue west
to the Agua Fria River. The study identified drainage problems, updated the existing hydrology due to development and
new hydrologic methodology, developed cost effective solutions for a stormwater collection and conveyance system
and identified potential outfall alternatives. The design and construction phase will involve the implementation of
solutions to flooding that are identified once the planning and conceptual design phases have been completed, and
remedial actions have been specified. Total expenditures proposed for the CIP are now estimated at $130 million for
identified projects, which includes the costs for the 75th Avenue Storm Drain & Durango Regional Conveyance
Channel.

The Arizona Department of Transportation (ADOT) has proposed a channel and basin improvement project for
Scatter Wash immediately downstream of Interstate 17 (I-17). This project would be a joint project among ADOT, the
City of Phoenix and the Flood Control District. The project would provide 100-year flood protection to this reach of
Scatter Wash, and would consist of improvements to Scatter Wash at the I-17 crossing, channel improvements
downstream of I-17 and construction of an off-line basin. It is proposed that ADOT be the lead agency for design and
construction and that the City would own, operate and maintain the channel and basin improvements. The District
Board of Directors has approved a Resolution for the project, and the project partners are now in the process of
developing an Intergovernmental Agreement. ADOT will include the design and construction of the project in
conjunction with improvements planned for I-17. The anticipated cost share for the project is 44% ADOT, and 28%
each for the City and the District.

The Bethany Home Road Outfall Channel project includes a linear basin and channel along the Grand Canal
extending westerly from 63rd Avenue to the New River. The project will have a 100-year capacity removing
approximately 745 structures from the floodplain. The channel alignment (Phase I and II) is in Phoenix, Glendale, and
unincorporated Maricopa County. Portions of the channel are being used as a trail corridor and linear park.
Phase I of the project has been completed by ADOT, with District participation. Phase I extends west from the Agua
Fria Freeway to the New River following the Bethany Home Road Alignment. ADOT increased the size of their
channel to accommodate additional flows from the Maryvale area.
Phase II of the project includes a channel from the Agua Fria Freeway alignment to 63rd Avenue. The ADMP also
recommends ten-year capacity storm drains, located within Bethany Home Road and Camelback Road, extending from
59th Avenue to the Outfall Channel. Preliminary estimates indicate that the cost to construct this 100-year channel and
10-year storm drains is approximately $67 million. The cost share for the project is approximately 50% District, and
25% each for the Cities of Glendale and Phoenix. The first reach of the Phase II project (Loop 101 to 83rd Avenue)
is completed. Design and construction of the remainder or the improvements will be phased over several years, with
completion anticipated in 2009.

The City of Phoenix has accepted the Maryvale Area Drainage Master Plan (ADMP) as the hydrological basis for future
drainage improvements within the ADMP watershed. A Design Concept Report for 26thAvenue & Verde Lane was
prepared by the City of Phoenix. The recommended basin alternative will provide a retention volume for the 100-year,
24-hour storm for the local drainage area. The recommended alternative will incorporate a storm drain system
designed to intercept flow from along the I-17 frontage road. Flows will be intercepted along 25th and 26th Drives,
eliminating flooding for storms up to and including the10-year event. The Verde Lane Detention Basin will provide a
positive outfall location for the proposed storm drains thereby precluding ponding from occurring within the streets
and houses. The new basin will drain into the existing 27thAvenue storm drain system after the peak flows have passed.
This project cost will be shared equally with the City. The project is in the 60% design stage and construction is
scheduled for FY 2006.

Less than 18% of the estimated 9,800 miles of stream corridor in Maricopa County have been mapped with regulatory floodplains
and floodways. In many of the mapped areas, development took place prior to the floodplain mapping. As floodplains were
delineated, many residents learned that their homes were within a regulatory floodplain. The Floodprone Property Acquisition
Program (FPAP) is a voluntary program that was developed to help residents that were identified as being in a flood hazard area
where a structural flood control solution is not feasible or cost effective.
Property owners that have properties located in floodprone areas are typically contacted by mail to inform them that they may be
eligible for this program. If property owners are interested in the program, they submit an application to the District for evaluation.
After an application is received, the property is evaluated for eligibility and ranked based on the degree of flood hazard. The degree
of flood hazard is based on whether the residential structure is in the 100-year floodway or floodplain fringe, the finished floor
elevation of the structure, the velocities and depths of the 100-year floodwater, previous flooding events, and other related criteria.
After the District acquires the properties and the residents move, all of the structures are demolished and removed from the
property. Depending on the property location, the property may be preserved as open space in-perpetuity, sold, or leased for uses
compatible with adjacent properties and floodplain regulations.
In FY 04/05, 30 property owners applied to the program and 15 properties were acquired by the District. The budget for FY
05/06 is approximately $3,000,000. The FPAP is an annual program that is expected to continue for many years.
