There is one elected official from each of the five County districts. The Board of Directors makes the final decision regarding projects to be included in the Capital Improvement Program. District 1 Fulton Brock District 2 Don Stapley District 3 Andrew Kunasek District 4 Max Wilson District 5 Mary Rose-Wilcox 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, drainage, 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 and the Drainage 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 2:00pm in the Flood Control District Administrative Building. Please contact the Flood Control District at (602) 506-1501 to confirm that a meeting is scheduled to occur. District 1 Scott Ward District 2 Kent Cooper District 3 Hemant Patel, P.E.

Project Evaluation Committee The Project Evaluation Committee, comprised of senior District managers, make CIP recommendations to the Chief Engineer and General Manager and the FCAB Program and Budget Committee. Their recommendations are developed using a system that allocates points to individual projects based on specific criteria. For more information, see section 2.4 Prioritization Criteria on Page 9. The committee members are: George Lindop: Inspections Branch Manager Amir Motamedi, P.E.: Hydrology & Hydraulics Branch Manager Dick Perreault: CIP/Policy Branch Manager Ed Raleigh, P.E.: Engineering Division Manager Jim Schwartzmann: Land Management Division Manager 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 4 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 sevenmember 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 (2001/2002) was $0.2319 per $100 of assessed value. The tax levy rate for Fiscal Year 2002/2003 has been set at $0.2119 per $100 of assessed value. The District is organized into seven functional areas arranged in the following divisions: Administration, Operations & Maintenance, Engineering, Regulatory, Land Management, Information Technology, 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 2002 through June 2007. 1.2 What is the Capital Improvement Program? The Capital Improvement Program (CIP) for the Flood Control District is a 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 5 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 fiveyear 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 What is 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 CIP is that the capital budget gives the District staff authority to spend funds and proceed with specific projects. The CIP includes both first-year projects as well as future projects for which financing has not been secured or authorized. The “out years” of the plan are projected, but not authorized and hence are subject to change. Every item in the capital budget must be approved by the Board of Directors 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 Five-Year 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 capital projects more easily than the one-year capital budget. 1.4 Why Undertake 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. 6 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 called for in 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 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 and accommodated. This is possible provided the use does not diminish the flood control projects’ primary purposes. In addition, the project costs and the facility’s maintenance requirements should not be significantly increased. 7 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 combined Planning Program and Capital Improvement Program account for approximately 75% of the total Flood Control District annual budget. During FY 2001/2002, the District, in cooperation with other agencies and municipalities, completed 6 major long-term flood control capital projects and continued or initiated capital operations on 12 other projects. At the outset of Fiscal Year 2002/2003, 6 CIP projects are in the construction stage, 10 are being designed, while 10 are in the planning and/or land acquisition stage. In addition, the District will initiate effort on 9 new projects during the year by pursuing Board of Director’s 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 Master 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. 8 The proposed FY 2002/03 planning program will continue ten studies initiated during Fiscal Year 2001-02; eight (8) Master Plan studies (Scottsdale Road, Granite Reef, Carefree, Rio Verde, Wittmann, Adobe Dam/Desert Hills, Buckeye/Sun Valley, and Aguila), and two (2) Watercourse Master Plans (Agua Fria and El Rio). The proposed planning program also includes Candidate Assessment Reports to develop information for candidate projects to the District’s Capital Improvement Program. The proposed planning program for FY 2002-2003 also includes one (1) new Watercourse Master Plan (Lower Hassayampa River WCMP) and continuation of the existing Structures Multi-use and Aesthetic Evaluation Project for evaluation of existing structures which have not been funded but will be implemented should sufficient funding is made available in a timely manner. 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. 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 2001. 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 are included in a District-funded and prioritized pre-design study program. Requesting agencies may complete prioritized pre-design studies using consultants or in-house resources, 9 provided the information produced meets the minimum requirements of Districtsponsored 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 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 10 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 competencies 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 a significant feature of 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. The District is a partner in a number of efforts such as the Marathon Trail and the Bethany Home Outfall Channel Project, where flood control facilities are included as part of major urban redevelopment, environmental restoration and/or large scale recreational facility development. If resources are available, many existing flood control systems and facilities in established urban areas could be retrofitted or altered to allow for additional benefits or activities. Many District rights-of-way or facilities offer the potential to also provide bicycle/walking paths, habitat for native species, or attractions for local businesses, without threatening the underlying flood control role of these projects. The Bethany Home Outfall Channel Project was identified in the Maryvale Area Drainage Master Plan (ADMP). The project includes a linear basin and channel along the Grand Canal extending westerly from 64th Avenue to the New River. The project will have a 100-year capacity removing approximately 745 structures from the floodplain. The channel alignment is in Phoenix, Glendale, and unincorporated Maricopa County. Portions of the channel are being used as a trail corridor and linear park. 11 The Project will extend along Bethany Home Road easterly from the Agua Fria Freeway and along the Grand Canal to 64th 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 estimated at 50% District, and 25% each for the Cities of Glendale and Phoenix. Six public meetings have been held and six newsletters sent out since 1999 to inform the public regarding the project, and to gather public input. A goal of the project partners is to minimize the adverse impact of the project to the neighborhoods along the corridor. Construction times and methods will be controlled to limit noise and dust as the project is being built. One segment of the project (73rd Avenue to 67th Avenue) requires the acquisition of 72 residences. In addition to the public meetings and newsletters that have informed the public about the project, these 72 residences have been contacted separately by the District, to ensure that they are informed of the project impacts as much as possible. In order to minimize the impact to these residents, the District has worked to maintain the schedule for acquisition of the properties. The District has also worked to accommodate requests from those residents desiring to be in the first group of properties to be purchased. The first reach of the project (Agua Fria Freeway to 83rd Avenue) is scheduled for construction beginning in early 2003. Design and construction of the remainder of the improvements will be phased over several years, with completion anticipated in 2009. The Laveen Area Conveyance Channel (LACC) Project represents a cooperative effort among the Flood Control District (FCD), City of Phoenix (COP), Salt River Project (SRP), Maricopa County Department of Transportation (MCDOT) and local landowners, to develop, design and construct a project that will provide a multi-use regional flood control and linear park facility. As lead sponsoring agency, FCD is developing the design for the 5.8 mile long flood control channel and 16 acre detention basin. The Project will include a 200-foot wide corridor for a grassed channel and adjoining park area. The channel will convey the 100-year flood and include a low-flow channel, which will convey existing irrigation tailwater to the Salt River. The COP is developing agreements with the Project landowners, to acquire the land needed for the Project at no cost, and provide incentives such as open space credits and relief of retention requirements. The low flow channel will convey water that currently is conveyed in SRP’s tailwater ditch known as the Maricopa Drain. SRP will maintain the low flow channel upon Project completion. COP will maintain the flood control channel. MCDOT will provide funding to the Project, which will facilitate their planned upgrade of Baseline Road. FCD and COP are working together to incorporate low-cost aesthetic treatments of project features into the design. Construction of the basin is expected to begin in the spring of 2003, and channel construction is expected to begin in mid-2003, with completion by early 2004. 12 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. 13 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 set annually by the Board of Directors. 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 County-wide. 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 fallen significantly, and 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. It is anticipated that the District’s tax revenues will need to be increased above the current $45 million level if projects in the CIP are to be funded and schedules are to be maintained.

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. More recently, 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 15 FY 1992/93, they had grown to approximately $7 million by FY 1996/97, to $17.2 million in FY 2001/2002. 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 2001/2002 more than a third of the capital program budget was provided by other government entities. The depressed economy during the last 18 months has affected the ability of the District’s partners to cost-share future projects. Expenditures made by the District to operate and maintain flood control structures and adjacent property are substantial; in FY 01/02 these operations and maintenance (O&M) costs were approximately $3.6 million, or about 5.4% 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 projects since the early 1990s, the District will spend a smaller percentage of its budget on O&M annually. 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: • An increased 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 non-structural approaches such as flood plain delineation and management, natural watercourse improvements, and/or minor improvements to natural 16 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 years (FY 2002/2003 through FY 2006/2007) and summaries of the CIP budget that show projected expenditures by “Area” (groupings of projects) and by “Project” (individual facilities and systems). Table 3 (Final) from FY 2002/2003 provides a summary of the results of the FY 2002/2003 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 CIP budget in the Summary and Detailed Spreadsheet is provided in two different formats. Each summarizes estimated expenditures for all projects proposed for the District's Five-Year Capital Improvement Program for fiscal years 2002/2003 through 2006/2007. The first format is a summary of all of the CIP expenditures by “Area”. Every Project Control Number (PCN) is made up of a seven-digit code that is used for tracking financial costs. The first three digits identify the “Area”, or clustering or family of projects, and this is the level of detail that is used in the summary of CIP expenditures. For example, the White Tanks “Area” code includes five “Projects” that originated from the White Tanks Area Drainage Master Plan. In the summary, these individual “Projects” and their “Components” are not shown. The second format provides a more detailed listing of expenditures by individual projects, which are shown with both the three digit “Area Code” and the two digit “Project Code”. 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 17 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. The project managers responsible for each project and how to contact them is listed with the project descriptions. 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.

During previous years, the District has acquired semi-rectified aerial photography with a horizontal accuracy of +/- 25 feet in urban areas and +/- 300 feet in rural areas. This accuracy is insufficient for depicting floodplains or overlaying any other available data at the District. It has been determined that a better accuracy is necessary for the District’s regulatory and technical responsibilities. An ortho-photography digital aerial contract was specified with horizontal accuracy of +/- 5 feet and vertical accuracy of +/- 5 feet. Aerial photographs of Maricopa County were taken during the months of December 2001 and January 2002. The ground control used for the project is the Geodetic Densification and Cadastral Survey generated by the Maricopa County Department of Transportation. Airborne GPS was used to control the project. A ground size pixel of 1 sq. foot was specified. When the project is completed it will be used for Zone A floodplain determinations, for accurately depicting features on the ground and for floodplain determination on the District web site.

The City of Chandler previously developed and implemented a storm water master plan for the central area. The City updated the plan and has requested that the District cooperate and cost share the modification and enhancement of the existing facilities to provide a 100-year level of protection and a regional outfall for the system. The City is the lead agency for design, rights of way acquisition, utility relocation, construction, construction management, and operation and maintenance of the system. The District’s role is to participate in the consultant selection process, pre-construction meetings, provide technical assistance, and review the design and construction phases for the Project. Five improvements have been identified that would help the City accomplish its goal of alleviating the flooding problems in the Chandler’s central area. Total project cost is estimated at approximately $ 12.2 million with the District’s contribution capped at $ 6.1 million.

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 in Tempe. The three basins within the Town will be landscaped and become Town parks after construction. The basin in Tempe, because of its small size and its depth will be landscaped and fenced. The project costs for design, right-of-way acquisition, utility relocation, environmental studies and construction of the project are estimated to be less than $7 million. Construction of the project began in March 2002 and is scheduled for completion in February 2003. The Town is not able to contribute financially to the project but will own, operate and maintain the storm drain system and the four basins. Additionally, the Town will seek grants and other means to fund future street drainage improvements that will utilize the present project as an outfall.

The District has developed a process that includes evaluation and ranking of the candidate projects based upon specific evaluation criteria. A Candidate Assessment Report (CAR) is recommended when the review committee feels that the material submitted for the proposed project is insufficient to support the ranking or there is insufficient project detail to implement the project. The CAR studies are used to document the project requirements, benefits and costs. The studies are generally limited to an assessment of existing data. The study purpose is to confirm or expand on the information provided for the project prioritization and to document the requirements for implementation of the project. Upon completion of the annual CIP prioritization, the list of projects submitted which require a CAR study is completed and the CAR studies initiated. If the CAR findings indicate that the project benefits or cost are substantially different than the project data originally submitted for the CIP prioritization, the project may be resubmitted for another evaluation and ranking by the CIP review committee. A CAR study has been completed for the Broadway/Rural area in Tempe during FY 2002-2003. Additional CARs will be identified with completion of the District’s CIP Prioritization for FY 2003-2004 in December 2002.

A flood detention basin at 43rd Avenue and Southern Avenue will mitigate peak flood flows getting to the conveyance channel. Based on previous evaluations of flood hazards within this area, significant floodwater from large storm events pond along the existing Maricopa Drain. This project will reduce the potential flood hazard. This project consists of channel excavation, road crossings, drop structures, tiling and filling in the existing Maricopa Drain, and construction of an earthen low-flow channel. The channel and basin will be grass-lined to reduce and/or eliminate erosion and sediment transport and to provide landscaping and aesthetics. The peak discharge at the outfall of the channel for the 100-year storm event is estimated to be 2800 cfs. The existing Maricopa Drain has a much lower capacity and carries agricultural tailwater continually to the Gila River Indian Reservation, and some of this water outfalls to the Salt River. This water will be carried in the Project’s low-flow channel, and outfall near the existing outfall location.

The South Phoenix Drainage Improvement Project will provide protection from a 100-year 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 proposed system is composed of underground pipes and detention basins that will help to minimize the project’s cost. It is estimated that the project will cost $25 million to design and build. Elements of the project will be constructed in phases through a joint partnership among the District, the City of Phoenix, and the Maricopa County Department of Transportation. The storm drains in Baseline Road (7th Street to 43rd Avenue) and in 43rd Avenue to the Salt River have been constructed. The South Phoenix Two Basins are located at the intersections of 43 rd Avenue and Baseline Road, and 27th Avenue and South Mountain Avenue. Preliminary designs have been prepared for each of the detention basins. The Two Basins were submitted by the City of Phoenix in the 1999 Prioritization Process, and approved by the Prioritization Committee. The City of Phoenix does not have funding in their current bond program for this project. 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. Depending on funding participation, some project elements may be deleted, downsized or deferred, possibly resulting in a reduced level of protection.

The study identified several drainage and flooding problems along the EMF. The capacity of the EMF is at about 8,000 cfs. The existing condition 100-yr. is about 16,000 cfs. The study proposed to mitigate the problem by constructing two large off line retention basins. The Chandler Heights Basin is planned as an off line basin to mitigate flows from the Sanokai Wash, Queen Creek Wash, and the EMF. Rittenhouse Basin is also planned as an off line basin to mitigate flows from the Rittenhouse Channel and the EMF. The completed basins are planned to be used by the Town of Gilbert for recreation. The Town shall fund the recreation amenities. The project consists of a pre-design, and a final design to include; preparation of construction plans, special provisions and engineer’s estimates. The design cost is currently estimated at $2 million. The preliminary construction cost is estimated to be $26 million. The design of the project is scheduled to be complete in FY 02/03.

The town is located in the extreme northwest corner of Maricopa County about 25 miles west of Wickenburg, Arizona along U.S. Highway 60/70. On November 21, 2000 a severe rainstorm flooded the area, which caused extensive damage to homes and placed lives in danger. As a result of the flooding, the District and FEMA conducted a study of the flooded areas that surrounded the town, and on the Grass Wash area, which runs through Aguila. An assessment of the damage was made and then the decision to acquire the property and relocate the residents. The District submitted an application to FEMA asking for a grant to acquire and relocate the residents. The Aguila Hazard Mitigation Grant was approved and FEMA awarded the District the sum of $ 815,000. The estimated cost of the project is $977,300; the District pledged the additional money or about 10% so that the project could be completed. Acquisition, relocation, and then demolition of the homes in the floodway will be a 2FY 03: $0 FY 04: $0 year project scheduled to be completed in late 2002.

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 extends along Elliot Road from the 104 th 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 in six natural washes. The Elliot Road Detention Basins, located along Elliot Road near Crismon Road, have been deleted from this project. The future Phase 1B will extend from Ellsworth Road to the East Maricopa Floodway, and may include basins to attenuate peak flows to reduce the size and cost of required downstream improvements, and meet the capacity restrictions of the East Maricopa Floodway. The City of Mesa may be interested in creating a joint use for the channel and basins as a park.

The District recently constructed detention basins downstream of the CAP overchutes to capture the flows and reduce the peak flow in the existing washes and channels. The outfall channels and / or washes from the basins along the CAP Canal drain into a channel along Hawes Road. This channel splits into two channels: a channel along Southern Avenue from Hawes Road to 78th Street, and a channel along Hawes Road from Southern Avenue to the Superstition Freeway. The channel along Southern Avenue is an integral part of the drainage system in this area. The existing channel does not have adequate capacity to convey the 100-year flow. Thus, the channel was reconstructed as a box culvert. The City of Mesa has acquired rights-of-way, completed design, relocated utilities and has completed construction of this project. The District will cost share 50% of the project and Mesa will own and operate the completed project.

The recommended plan in the southern portion of the study area includes channels along the eastern side of the Eastern and Consolidated Canals extending south from the proposed San Tan Freeway. The proposed channels will convey flood flows across the Gila River Indian Community southerly to the East Maricopa Floodway. Five detention basins are also proposed to reduce the size of the channels. The Queen Creek Road Storm Drainage Basin is the first element in implementation of regional flood control infrastructure as identified in the Higley Area Drainage Master Plan. The basin is generally bounded by: Queen Creek Road on the north; the Section Line 1/4 mile east of McQueen Road on the east; the Section Line 1/2 mile south of Queen Creek Road on the south; and McQueen Road/Consolidated Canal on west. The basin property is approximately 70 acres in size.

Successful implementation of the recently completed Skunk Creek Watercourse Master Plan (WCMP) and the Cave Creek/Apache Wash WCMP is largely dependent upon prudent and ongoing management of the watersheds that supply runoff to the WCMP corridors. The Adobe Dam/Desert Hills ADMP project will incorporate existing drainage facilities and policies into the modeling process, and develop alternative solutions for the entire Adobe Dam/Desert Hills watershed. The project will link management of the watershed to implementation of the WCMP’s by making recommendations that support the corridor management tools adopted for the Skunk Creek and Cave Creek/Apache Wash WCMP corridors. The major objectives of the project are to quantify selected drainage, flooding, and erosion hazards within the project area; alleviate potential flood and erosion damage within the watershed by mitigating the expected increase in runoff due to development and preserving the ability of the primary wash corridors to convey stormwater; coupling management of the watershed with recently adopted WCMP corridor management tools for the Skunk FY 03: $1,021,000 Creek and Cave Creek/Apache Wash corridors; develop a plan that area floodplain FY 04: $150,000 managers, municipalities, and developers will use as a basis for drainage and watershed FY 05: $0 regulation, improvements, and design; and identify cost-effective, sustainable flood and FY 06: $0 erosion control solutions for the project area that may be implemented together or FY 07: $0 individually, based on scheduling, funding, and cost sharing. 5-Yr CIP: $1,171,000 Origination: FCD Staff Recommendation – ongoing Planning Program Authorization: FCD Project Manager: Phone: 602-506-4766 mdr@mail.maricopa.gov Marilyn DeRosa, R.G.

Once mapping was complete, several of these residents learned that their homes were within a FEMA 100-year Floodway. These homes have a higher risk for flooding than those outside the floodway and, when the floodplain is active, the presence of these structures in the floodway can create adverse impacts to adjacent homeowners. In other circumstances, residents were outside the regulatory floodway, but found themselves in designated areas of severe erosion hazard due to unique local geologic characteristics. All of these structures would be susceptible to varying degrees of damage from water and water-borne sediments, and may be threatened by erosion of the stream banks caused by high water flows. In fact, a hazard analysis shows that these residents have a relatively high risk of injury, death, and/or property damage due to flooding and/or erosion. Most important, perhaps, is the very short time interval between the most intense watershed precipitation and when the flow reaches hazardous levels at the effected residences, referred to as the Emergency Response Time (ERT). This time interval is the time available to effect a coordinated flood warning and response. With an ERT of less than one hour, these residents are at a substantially increased risk for injury or death.

Several homes along Doubletree Ranch Road have experienced flooding during past storms, and children have been stranded at a local grade school, whose access becomes inaccessible during heavy rains. Two major watersheds, Doubletree Ranch Road and Cherokee Wash, exist within the project area. The Doubletree Ranch Road watershed begins in the Phoenix Mountain Preserve west of Tatum Boulevard and flows eastward along Doubletree Ranch Road to Indian Bend Wash. Cherokee Wash, which is located south of the Doubletree Ranch Road watershed, also begins in the Phoenix Mountain Preserve west of Tatum Boulevard, but then flows northeast to Indian Bend Wash. The project consists of a 10-year storm drain system in Doubletree Ranch Road, with storm drain laterals extending along the adjacent streets. In addition, surface flows greater than the 10-year flows will be to be conveyed on the surface of Doubletree Ranch Road. The cost of the drainage improvements is estimated at $10.3 million. The drainage improvements will be funded 60% by the District and 40% by the Town of Paradise Valley. The District is the lead in the construction, construction management and rights-of-way acquisition. The Town will operate and maintain the constructed facility. Improvements to Doubletree Ranch Road will be constructed with the drainage improvements, at Town cost. The project has been designed, and construction is scheduled to begin in FY 02/03.
