The District is a political subdivision of the state, and has the powers, privileges and immunities generally given to incorporated cities and towns. The District is governed by a Board of Directors, and is funded primarily by a flood control tax levy assessed on real property within Maricopa County and by District cost-sharing agreements with project partners. 1.2 Structure The Maricopa County Board of Supervisors serves as the District's Board of Directors, with the advice of a Flood Control Advisory Board comprised of citizens appointed by the Board of Directors, as well as ex-officio representatives of the City of Phoenix and the Salt River Project. The District is comprised of five divisions, operating under the oversight of its Chief Engineer and General Manager: Administration; Operations & Maintenance; Engineering; Floodplain Management and Services; and Planning & Project Management, which oversees the District's capital projects. 1.3 Mission The District provides regional flood hazard identification, regulation, remediation and education to Maricopa County residents so they can reduce their risks of injury, death and property damage from flooding while still enjoying the natural and beneficial values served by floodplains. Capital Improvement Program 2.1 Capital Improvement Program Overview The District primarily accomplishes structural flood hazard mitigation through its five-year Capital Improvement Program – the revolving funding plan for accomplishing capital projects. Under this program, the District has participated in the construction of over 110 flood control structures. Guided by strategic goals and objectives, this plan drives design and construction of new infrastructure in concert with the District's planning activities, while it simultaneously addresses modification and replacement of existing infrastructure. Capital projects typically account for approximately 60% to 65% of the District’s annual expenditures. The District manages its Capital Improvement Program as mandated by state statutes under the direction established by the following Board of Directors policy resolutions:     FCD FCD FCD FCD 2010R008, General Funding Policy 93-03, Landscaping and Aesthetics Policy 2006R003, Floodprone Properties Assistance Program 2009R003A, Small Project Assistance Program 1 Prior to their inclusion in the Capital Improvement Program, most capital projects are evaluated under the Capital Improvement Program Prioritization Procedure (regional projects), Small Project Assistance Program (local projects) or Floodprone Property Assistance Program (floodprone property buyout). The District’s Board controls aggregate funding for each of these programs. 2.2 Prioritization Procedure and Primary Capital Improvement Program The District's Prioritization Procedure, initially implemented for the Fiscal Year 1995 budget cycle, serves as the primary annual mechanism for evaluating new proposed capital projects for possible funding. The Prioritization Procedure promotes a balanced approach to the evaluation of proposed projects. The District attempts 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 also promote community development, protect natural habitats and maintain watercourse flow paths. The procedure favors projects that involve cost-sharing partnerships, allowing the District to best leverage limited financial resources. All newly proposed projects are evaluated according to predetermined and weighted criteria by a Project Evaluation Committee comprised of senior representatives of the District's Engineering, Operations & Maintenance, Planning & Project Management, Floodplain Management & Services and Real Estate divisions. The committee develops its recommendations using a system that allocates points to individual projects based on specific criteria. Project Evaluation Committee recommendations are forwarded sequentially to the Chief Engineer and General Manager, the FCAB Budget Subcommittee and the FCAB for approval. Evaluation criteria, last updated in December 2008, include:          Priority to Submitting Agency Flood Control / Drainage Master Plan Element Flooding Threat Level of Protection Area Protected Ancillary Benefits Total Project Cost Level of Partner(s) Participation Operations and Maintenance Costs to the District The District hosts periodic workshops to educate customer agencies on this procedure. In addition to its use in evaluating new proposed projects, the Prioritization Procedure also governs maintenance and safety-related modifications to existing structures operated and maintained by the District. These modification projects may be recommended by the Chief Engineer and General Manager independent of the committee-based evaluation process. The expenditure of funding toward a project recommended under the Prioritization Procedure will not occur until the District's Board of Directors has adopted a formal resolution authorizing the project to move forward. Following resolution adoption, for multilateral projects, District staff work with partnering municipalities to develop project IGAs that generally must be in place before project activity begins. 2 2.3 Small Project Assistance Program The Prioritization Procedure is intended to address projects that provide regional solutions to regional flood hazards. The District has recognized that, particularly in urban areas, localized flooding hazards exist where major structural solutions would be impractical. The Small Project Assistance Program provides a mechanism for the District to commit funding, on a limited basis, to advancing localized solutions in these situations. This program, initially authorized in May 2009 under Resolution FCD 2009R003, funded a first round of local drainage construction projects through Fiscal Year 2011. Resolution FCD 2009R003A extended the Program indefinitely. The program terms restrict per-project District funding to $250,000 or 75% of project construction costs, whichever is less. Submitting municipalities are solely responsible for project design, rights-of-way acquisition, utility relocations, construction management, and operations and maintenance, and are responsible for construction costs in excess of the District's contribution limit. Projects submitted under this program are evaluated each October, under an entirely objective method, based mainly on the frequency and severity of property flooding mitigated by the proposed project, and based on project implementation readiness. Individual project resolutions are not required for projects recommended under this program. IGA terms for these projects are non-negotiable, and IGAs are required to be in place in advance of expenditure of reimbursable project costs. 2.4 Floodprone Property Assistance Program Similar to the Small Project Assistance Program, the Floodprone Property Assistance Program provides a tool to mitigate flood hazards where structural solutions are impractical. Homeowners living in residences within delineated floodplains are eligible to apply for assistance under this program – applications are due each spring. Assistance generally takes the form of voluntary buyout, with the District purchasing the property at appraised market value. The District demolishes structures on purchased properties. District Financing 3.1 Financial Philosophy Most large government and private sector organizations that plan and construct large projects over extended periods of time borrow funds to finance these large projects, and then pay for them over many years. The District operates on a "pay-as-you-go" basis: the District's entire Capital Budget is funded from current revenues, and no borrowing takes place to finance capital projects. The District carries no debt load, and County taxpayers do not pay for interest charges on District structures. Since much of the District's revenues are spent on the capital projects, taxpayers are investing in the future of the County, their property and their safety. 3.2 Flood Control Tax Levy Overview The majority of the District's revenue is derived from a flood control tax applied to secondary assessed real property valuations. The District's Board of Directors and the County's Board of Supervisors set the flood control tax rate and assessed property valuations, respectively. The 3 flood control secondary assessed value, and as a result the District's revenue, is subject to economic influences. Maricopa County conducts annual market studies to determine individual property assessed values, and resulting tax levies generally lag these market studies by 18 to 30 months. So the market study conducted to determine property values in December 2011 will impact the District’s tax revenue in Fiscal Year 2014. This simplifies the District’s financial planning process, allowing accurate revenue projections for a two fiscal year period. To prevent large fluctuations in property owners' tax levies, the Board of Directors established a 2% levy growth limit in 2006. The overall levy generated from property taxed in a given fiscal year cannot increase by more than 2%. The flood control tax rate is set to enforce this policy and is then applied to all property - including new or previously untaxed property. Large increases in secondary assessed values result in correspondingly large decreases in the flood control tax rate. Between Fiscal Year 2007 and Fiscal Year 2008, for example, the flood control tax rate decreased from $0.2047 to $0.1533 per $100 assessed value. This offset a 36% increase in the flood control secondary assessed value of property taxed in Fiscal Year 2007 and, when combined with tax revenue from newly constructed property, resulted in an overall tax levy increase of 5% when compared to the originally projected Fiscal Year 2007 tax revenue. 3.3 Flood Control Tax Levy History and Trends Over the past 21 years, the flood control tax rate generally experienced a steady decline, while annual revenue slowly grew. However, this growth trend reversed beginning in Fiscal Year 2011, consistent with the recent decline in the real estate market and lagging value assessments. The District positioned itself to sustain operating capabilities during years of reduced tax revenues by developing a long-term revenue and expenditure forecasting model that identified the need to build fund balance reserves. The District executed recommendations of that plan, holding its capital budget fixed during periods of revenue growth and selling excess property. In parallel, the District has worked to maximize the efficiency of its operations and its project delivery. While many public works agencies have turned to alternative project delivery mechanisms that trade cost-cutting competition for shorter contract durations (e.g., DesignBuild and Construction-Manager at Risk), the District has favored traditional bid-build competitive construction contracting on its non-Dam projects. In the current economic environment, this has resulted in extraordinary cost savings, with District construction bids averaging 20% below engineers’ estimates since January 2010. The corresponding $20.3 million savings has allowed the District to accelerate capital projects, putting flood hazard mitigation structures in place both ahead of schedule and under budget.

In the 1990s, the District replaced larger government agencies as the primary source of technical expertise and financial resources for flood control in Maricopa County. To continue to address a wealth of regional flood control problems with its limited resource pool, the District has increasingly leveraged the financing of local project partners. The District aims to fund one-half of a project's design and construction costs and obtain the remaining funding from benefitting municipalities and other public and private agencies. Where possible, the District additionally defers maintenance responsibilities to partner agencies. Use of this Document Project budget tables are presented for the District’s five-year Capital Improvement Program, Fiscal Years 2014 through 2018. Fiscal Year 2014 figures represent the District’s Capital Budget as adopted by the District’s Board of Directors. Figures for Fiscal Years 2015 through 2018 are forecasted projections and may experience significant change, particularly for projects in the early stages of development. Tax revenue trends may have an additional, substantial impact on project sequencing. The five-year Capital Improvement Program is a function of District revenue projections. The fiveyear program reflected in this booklet assumes that District revenue will support an annual $40 million Capital Budget for Fiscal Year 2014, $40 million from Fiscal Year 2014 through Fiscal Year 2016, and $37 million from Fiscal Year 2017 through Fiscal Year 2018. Additional revenues generated by excess land sales, intergovernmental agreements or unforeseen property value increases may allow for additional expenditures; revenue lags tied to declines in property values or a lack of contributing project partners may lead to a corresponding decrease in the District’s Capital Budget for a given fiscal year. 5 Listed project totals are totals for this five-year period; they do not represent total historical or anticipated project costs. Included with each project description is the name and contact information for the responsible project manager. Project managers may also be contacted through the general District switchboard at 602-506-1501.

The area is largely flat and primarily drains through the city’s Arizona Avenue and Alma School storm drain systems; however, the drainage system also makes use of the Salt River Project “Chandler Drain” irrigation tailwater system. Recommended by the city’s Storm Water Master Plan Update, the Central Chandler Storm Drain Improvements Project removes all local drainage connections to the Chandler Drain, reducing the chances of pollutants from this irrigation system being introduced into the city’s storm drain system, establishes a distinct city storm drain system and provides a 10-year level of protection to the two-square-mile affected area. The District anticipates entering a cost-share agreement for design and construction of the project; however, implementation of the project is dependent upon availability of city funding.

The watershed area for this project is approximately 2.6 square miles and discharges into the McCormick Ranch Lakes drainage system. The section of the Upper Camelback Wash within the project area has two branches; the Main Branch and the 92nd Street Branch. Conveyance capacity of the existing system of open channels and street conveyance is limited to a 2-year event level in some areas, creating a flood hazard for an estimated 750 structures. Construction started in Fiscal Year 2013 and is being accomplished in two phases. Phase I construction along Cholla Street, 92nd Street and the main channel to Cactus Road, is ongoing and is expected to be completed in summer 2013. Phase 2, work north of Cactus Road, will begin immediately after Phase I and is scheduled to take 14 months to complete.

The District entered IGA 2001A009 with the City of Avondale, granting the city a non-exclusive easement over certain District fee-held land, including channelized portions of the Agua Fria River, to facilitate construction of a city trail system. Maintenance of the Agua Fria River levees poses a hazard to District personnel, as the levees were originally constructed without pipe rail fall protection, and a trail atop the levees would pose a similar hazard to the public. IGA FCD 2008A009 establishes a cost share between the city and the District for installation of pipe rail along levees between Buckeye Road and McDowell Road. The District's cost share is capped at $440,000, including a per-foot ceiling. The city, under the IGA, will act as lead agency for installation of the pipe rail, and will assume operation and maintenance responsibility over the installed railing.

The McMicken Dam Project includes McMicken Dam itself (approximately nine miles in length), the McMicken Dam Outlet Channel (approximately six miles in length) and the McMicken Dam Outlet Wash (approximately four miles in length) that discharges to the Agua Fria River. The ability of the McMicken Dam Project to maintain the current level of flood protection for the benefit of the public in an increasingly urbanized environment is in question due to its age, land subsidence, earth fissuring, urbanization encroachment and current dam safety standards. These safety issues have led the District to determine that an overall rehabilitation or replacement of the dam is required. Alternatives may include a modified dam, floodways or basins which will provide a minimum of 100-year flood protection. The District has pursued, and continues to pursue, federal funding assistance for this project; however, a lack of federal funding availability may require unilateral implementation. Design is in progress, and construction will be accomplished in multiple phases. Construction will include relocating the emergency spillway, improving the outlet channel and rehab of the dam embankment. Ongoing efforts are taking place to include the coordination of stakeholders for the incorporation of a recreational cost share component to the rehabilitation project.

Rainfall runoff from the South Mountain flows from the south to the north towards the Highline Canal. Approximately 0.65 square miles of watershed drains directly to the location of the Circle K Park and accumulates at that location. High volumes of floodwater will overtop the Highline Canal and proceed to pond in residential areas north of the canal. It is anticipated the project will construct a 35 acre-foot detention basin and provide a 10year level of flood protection.

The District’s 1995 Floodplain Delineation Study for Fountain Hills showed deficiencies at the Golden Eagle Park Dam on Ashbrook Wash, due to overtopping and potential dam failure. Dam safety improvements were made to the Golden Eagle Park Dam in year 2000 to prevent its overtopping and failure in the 1/2 Probable Maximum Flood. However, those improvements increased the regulatory 100-year peak flow downstream. The project will provide channel improvements to convey increased flood flow from the upstream dam and prevent the flooding of 13 residential properties adjacent to this wash reach, at the 100-year storm event. Improvements include replacement of corrugated metal pipes with new reinforced concrete box culverts, channel excavation, flood walls and re-vegetation. Design and construction timing is dependent upon the execution of an intergovernmental agreement and availability of District and town funding.

District maintenance activities require the use of these roads, potentially adversely impacting air quality. This project includes chip-seal improvements to much of the unpaved East Maricopa Floodway (EMF) maintenance roads. The U.S. Soil Conservation Service (now Natural Resources Conservation Service) completed the EMF in 1989 in partnership with the District and others. This 27-mile long earthen channel runs parallel to the Roosevelt Water Conservation District canal from north of Brown Road to Hunt Highway, and continues in a southwesterly direction through the Gila River Indian Community to an outlet at the Gila River. The EMF is a principal flood control feature for the east valley, intercepting floodwater flow impacting the Buckhorn-Mesa, Apache Junction-Gilbert and Williams-Chandler watersheds. The EMF is operated and maintained by the District, with the exception of segments that run through privately owned golf courses. This project includes chip-seal improvements to the unpaved EMF maintenance roads. Phase one of maintenance road improvements is complete. Future enhancements are dependent upon District funding availability.

In many of the mapped areas, development took place prior to the floodplain mapping, and as floodplains were delineated, many residents learned that their homes were within regulatory floodplains. The Floodprone Property Assistance Program (FPAP) involves the voluntary purchase of properties in flood hazard areas where structural solutions are infeasible or impractical. Program applicants are scored and ranked under objective criteria. Existing structures on purchased properties are demolished and removed; property may be preserved as open space, sold, or leased for uses compatible with adjacent properties and floodplain regulations. Due to funding constraints, new acquisitions are not anticipated during the five-year program.
