The PARA program is funded through the Federal Highway Administration’s ( FHWA) State Planning and Research program to non- metropolitan communities for the purpose of conducting transportation planning studies. PARA funds may be applied to address a broad range of planning issues related to road and non- motorized transportation modes. 1.1 Study Area Characteristics The Salt River Pima- Maricopa Indian Community is a sovereign tribe located on the east side of the Phoenix metropolitan area. It is bordered by the cities of Mesa and Tempe to the south, Scottsdale to the west and north, the town of Fountain Hills and the Fort McDowell Indian Reservation to the north, and unincorporated Maricopa County and Tonto National Forest to the east. The Community is a member of the Maricopa Association of Governments ( MAG), the municipal and intergovernmental planning organization for Maricopa County and the metropolitan Phoenix area. The study area for this LRTP is the SRPMIC itself. While Mesa, Tempe, Scottsdale, Fountain Hills, and Maricopa County were stakeholders in this planning study, the study area did not include land owned by any of these jurisdictions. Figure 1 shows SRPMIC in its regional context. Figure 2 shows the SRPMIC Long Range Transportation Planning Study Area. The Community is comprised of two Native American tribes with two distinct backgrounds and cultures: the Pima, " Akimel O'Odham" ( River People) and the Maricopa, " Xalychidom Piipaash" ( people who live toward the water). Although these tribes are distinct, the Community is considered in its entirety for this long range transportation planning study. SRPMIC encompasses approximately 85 square miles ( 54,632 acres), with 19,000 held as a natural open space preserve located primarily in the eastern portion of the Community. Elevations are higher in the open space preserve and the topography of the Sonoran Desert landscape is anchored by Red Mountain and Saddleback Mountain. The Verde River meets the Salt River east of Red Mountain. Many sensitive cultural sites are located across this open space preserve. The Central Arizona Project Canal traverses this preserve area. The Beeline Highway ( SR 87) cuts through this area providing a connection between Mesa and Payson. The Salt River runs along the southern edge of the Community, separating the Lehi area from the rest of the Community. Sand and gravel mining operations are located along the lower portions of the Salt River. The upper Salt River also serves as a barrier between the Community and the Tonto National Forest. Moving westward across the Community, the landscape transitions from open space preserve to agriculture. There are approximately 17,000 acres under cultivation in a variety of crops including cotton, melons, potatoes, onions, broccoli and carrots. Scattered residences are located in the agricultural area, primarily along the road grid. Irrigation water is pumped from 87 17 10 MARICOPA COUNTY 10 51 101 202 202 88 60 87 74 PINAL COUNTY Scottsdale Phoenix Mesa Tempe Glendale Fountain Hills Apache Junction Fort McDowell Indian Res.

The People’s Village with schools and housing is located at the center of the Community. The western portion of the Community is the interface between the rural Community and the urban centers of Scottsdale, Tempe, and Mesa. The Pima Freeway ( L101) runs north- south along the western edge. Two Community casinos are located in this area – one at Indian Bend Road, the other at McKellips Road. The Pima Road corridor is the Community’s commercial and industrial development area. The Community is building a Major League Baseball spring training facility on Pima Road between Indian Bend Road and Via de Ventura. 1.2 Indian Reservation Roads Program This LRTP meets an Indian Reservation Roads ( IRR) Program requirement. The IRR Program addresses transportation needs of tribes by providing funds for planning, design, construction, and maintenance activities. The program is jointly administered by the FHWA’s Federals Lands Highway ( FLH) Office and the Bureau of Indian Affairs ( BIA) in accordance with an interagency agreement. It provides guidance to tribes and tribal organizations for planning, designing, constructing and maintaining transportation facilities. It also establishes a funding distribution methodology to allocate funds based on the relative needs of tribal communities for transportation assistance. The BIA established final rules for the Indian Reservation Roads Program in the Federal Register Volume 69, No. 137, Monday July 19, 2004. The Indian Reservation Roads are public roads that provide access to and within Indian reservations, Indian trust land, restricted Indian land, and Alaska native villages. IRR funds can be used for any type of federal Title 231 IRR Requirements transportation project providing access to or within Federal or Indian lands and may be used for the state/ local matching share for apportioned Federal- aid Highway Funds. SRPMIC is a self-governance tribe under the Indian Self- Determination Act ( Public Law 93- 638) and manages Indian Reservation Road funding to maintain its current road system and construct new facilities. The IRR Inventory is a basic requirement for the funding allocation system. SRPMIC maintains a comprehensive database of all transportation facilities eligible for IRR funding. The inventory is approved by both the BIA and the tribe. The BIA uses this roadway characteristics data to generate the construction cost estimates and vehicle miles of travel ( VMT) components of the Relative Need Distribution Factor ( RNDF) for distributing IRR funds. Within SRPMIC, there are 178 miles of Indian Reservation Roads. More than 137 miles are under BIA and Community jurisdiction. The City of Scottsdale maintains pavement, drainage and traffic signals on seven miles of Pima Road. The Maricopa County Department of Transportation ( MCDOT) has jurisdiction of 11 miles, and ADOT has jurisdiction of 23 miles of road. The IRR roadway characteristics database includes classification, route number, bridge number, current traffic volumes, maintenance responsibility, and ownership. Appendix A shows the SRPMIC IRR System Inventory. In addition to a transportation facility inventory, the IRR Program also requires a LRTP. The purpose of the LRTP is to demonstrate a tribe’s transportation needs and develop strategies to meet these needs. The previous SRPMIC LRTP was completed in April 2001. A third IRR Program requirement is the Tribal Transportation Improvement Program ( TTIP). This document is consistent with the LRTP and contains all funded projects programmed for construction in the next three to five years. Typically, BIA selects projects from the TTIP based on funding availability on 1 Title 23 of the United States Code outlines the role of highways in the United States Code. 5 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan a state- by- state basis to develop an IRRTIP for approval by the Secretary of Interior and the Secretary of Transportation. 1.3 Community Outreach Two rounds of Community outreach were conducted for this long range transportation planning effort. The first round focused on issue identification and data collection. The study team conducted interviews with 18 stakeholders, attended Elders’ Breakfasts and conducted two Community Workshops. The team also met with the Young River People’s Council, attended district meetings and attended the Salt River Safety Day. The second round of Community outreach was intended to provide Community members with an overview of the LRTP recommendations and understand any other issues or concerns to be addressed in the study recommendations. The study team attended Elders’ Breakfasts, attended the SRPMIC Earth Day Celebration, conducted two Community Workshops and made two presentations to the SRPMIC Tribal Council. In addition, the study team held meetings at key project milestones with a Technical Advisory Committee ( TAC) that included representatives from ADOT, MCDOT, MAG, City of Scottsdale and SRPMIC. Appendix B includes meeting notes and summary reports from the outreach process. 1.4 Key Issues Key issues identified through the Community outreach process include regional population and employment growth, cut- through traffic, traffic safety, Salt River bridge crossings, public transit and bicycle and walking routes. Growth Population growth within SRPMIC has been relatively slow compared to the increases seen elsewhere in Maricopa County. Census 2000 showed a SRPMIC population of 6,405 living in 11,959 households. Maricopa Association of Governments ( MAG) estimated a July 1, 2008, population of 6,829 living in 2,083 households. This amounts to a 0.8 percent annual growth rate for the eight- year period. Comparatively, total population in Maricopa County grew at an estimated 33.2 percent annual rate for the same eight years increasing from 3.07 million persons in 2000 to 3.95 million persons in 2008. The SRPMIC Enrollment Office set the Community membership as 8,976 as of June 30, 2009. The Community’s statistics indicate that half of the tribe’s population is under age 21. Based upon 2000 Census data, it is critical to note that Community members are much less likely to move or change residences compared to non- members. Over the last decade, more than two- thirds of families reside in the same home. A portion of the SRPMIC membership lives outside of the Community itself. The more significant story within SRPMIC has been employment growth. The Community has developed two casinos – one on McKellips Road, the other on Indian Bend Road. The Pima Freeway corridor is designated for commercial mixed- use and has attracted significant retail and office development. In 2008, SRPMIC identified over 6.8 million square feet of non- residential building space either existing, permitted, or under construction within the Community. In early 2011, SRPMIC will open a new spring training facility located on Pima Road between Indian Bend and Via de Ventura to host the Arizona Diamondbacks and the Colorado Rockies. 6 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan SRPMIC members accustomed to the traditional tranquil way of life are concerned about the impacts on Community roads from the added traffic from both regional population growth and increased commercial activity on the Pima Road corridor. Cut- Through Traffic Cut- through traffic is the top concern for Community members. The issue was raised at the first TAC meeting, the Elders Breakfast, and at other stakeholder and special interest group meetings. Concurrent with this long range transportation planning study effort, the Tribal Council authorized a study by Red Mountain Engineering to identify short term solutions to the cut- through traffic problem. Increased traffic on Community roads has been driven by several factors. Overall regional population growth has meant more vehicles on all roads. The growing congestion on the regional freeway system such as the Red Mountain Freeway ( L202) and Pima Freeway causes drivers to look for shortcuts across the Community. The casinos and Pima Road commercial development are also attracting more trips to the Community. When Pima Freeway is closed by a severe traffic incident, the police department said that Pima Road is the primary traffic detour, which generates additional cut- through traffic across SRPMIC. Traffic Safety The SRPMIC Police Department said in a stakeholder interview that the highest crash locations are located on roads travelling between Pima Road and the Pima Freeway. Chaparral Road and McKellips Road have the highest number of crashes. Livestock- related crashes are prevalent along the State Route 87 ( Beeline Highway). Also along the Beeline Highway, some fatal crashes have occurred with vehicles entering from side streets and being hit by high speed cross traffic. Salt River Bridge Crossings The Salt River separates Lehi from the larger Salt River Pima- Maricopa Indian Community lands. Currently, there are four crossings of the Salt River between Mesa and SRPMIC: Alma School Road, McKellips Road, Country Club Drive, and Gilbert Road. In 2008, floods washed away the riverbed crossing of the northbound lanes of Gilbert Road from Mesa to SRPMIC. The McKellips Road crossing is also a riverbed crossing. In August 2009, MCDOT completed a Design Concept Report to identify preferred bridge locations and designs for crossings at Dobson Road, McKellips Road and Gilbert Road. Public Transit The Salt River Transit System ( SRTS) provides dial- a- ride services for Community residents traveling within the Community, and into Mesa, Tempe, and Scottsdale for shopping, employment, medical and social services. Both Community members and the transit service operators expressed a need for additional service with better connectivity to the regional transit system for access to health care facilities, shopping, work and other activities. Bicycle and Pedestrian Routes There is an overall lack of sidewalks and pedestrian amenities throughout SRPMIC. There are no designated bicycle routes or multiuse paths. During recent outreach, some have said that sidewalks are not a high priority. However, the Elders and the Youth Council both indicated a need to have a safe place for kids so that they do not have to walk in the street. The Elders expressed an interest in multi- use paths for bicycle, pedestrian, or equestrian use. Stakeholders from outside the Community have urged a 7 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan regionally connected multi- use path system. However, the Elders were adamant against providing additional access for the outside public to trespass on the Community. They suggested that any paths should be internal to the Community and not provide connections to encourage use by those living outside of SRPMIC. 8 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan This page is intentionally left blank. 9 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.0 Existing Transportation System Conditions This section describes the SRPMIC existing multimodal transportation system. It provides details on road network, public transit system, and bicycle and pedestrian facility characteristics. In April 2009, SRPMIC completed an inventory of all of the roads and bridges within the Community for the Indian Reservation Roads ( IRR) program. This inventory provides detailed information on road characteristics, including number of travel lanes, BIA functional classification, average daily traffic, route ownership, and surface condition. This section presents the road characteristics data collected by SRPMIC and augmented with data collected as part of this study. Information on the current public transit service and bicycle and pedestrian facilities from interviews conducted with SRPMIC officials is also included. 2.1 Previous Plans and Studies This section identifies previous and current transportation studies reviewed for the preparation of this document. ADOT Arizona Rural Transit Needs Study, 2008 The purpose of this study was to develop regionally based needs and solutions for rural transit service in Arizona. Transit demand in rural Arizona is projected to grow from 7.8 million passenger trips in 2007 to 10.5 million in 2016, an increase of 34 percent. Currently, only 18 percent of estimated demand for rural transit services is being met. Existing rural transit services are projected to meet only 13 percent of total ridership need in 2016 if no additional services are introduced. The study identified steps to address the transit needs of rural Arizona such as adding rural public transit service within cities, towns, and Tribal Reservations to assure service needs of the elderly, persons with disabilities, and the general public are met; connect rural and urban communities, which represents a growing Arizona need; increase funding at all levels of government to support these services, with cooperation from private and non- profit sectors; and, establish clearly defined roles and responsibilities between the state, councils of governments, local governments, Tribal Governments and transit operators. MCDOT Salt River Bridge Crossing Study, 2009 MCDOT has prepared a Design Concept Report ( DCR) dated August 2009 for three bridges to identify the preferred bridge locations and designs for bridges across the Salt River at Dobson Road, McKellips Road, and Gilbert Road. The report also scopes the widening of McKellips Road from the Pima Freeway to the Salt River. These projects are being developed by MCDOT in partnership with SRPMIC and the City of Mesa. The design effort will commence once a partnership agreement is completed on the $ 170+ million project. Pima Road Design Concept Report, 2009 SRPMIC, the City of Scottsdale and ADOT completed a Design Concept Report for Pima Road between McDowell Road and 90th Street. This study established the cross- section and alignment of this key north-south arterial along the Community’s commercial core. The study objectives included improving traffic operations to accommodate growth, improving business access, enhancing corridor character, accommodating multimodal access, and safeguarding adjacent neighborhoods and community resources. The recommended alternative includes four 11- foot travel lanes, two 5- foot bike lanes, and a 14- foot median. The Final DCR was published in October 2009. 10 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Red Mountain Engineering Cut- Through Traffic Study Red Mountain Engineering conducted a cut- through traffic study to identify potential solutions to reduce non- Community travel on SRPMIC roads between Scottsdale and Mesa. Recommendations from this study are incorporated into this Long Range Transportation Planning Study. SRPMIC General Plan, 2006 The SRPMIC General Plan is the Community’s blueprint for land use, development, conservation and preservation. It is the basis for decision making regarding long- term physical development and the protection of the Community’s cultural and natural resources. The plan focuses on establishing a framework of sustainability to ensure that the current and future generations can sustain the social, economic and environmental health of the Community. It includes a land use element and a transportation/ circulation element, which are key inputs into this current long range transportation planning effort. SRPMIC Indian Reservation Roads System Inventory, 2009 The IRR System was last updated in 2009 and included an inventory of all of the roads and bridges within the Community for the IRR program. This inventory provides detailed information on road characteristics, including number of travel lanes, BIA functional classification, average daily traffic, route ownership, and surface condition. The planning effort identified near- term roadway improvement needs that were adopted by the SRPMIC Council as an amendment to the 2001 Transportation Plan. SRPMIC Transportation Planning Study, 2001 The 2001 SRPMIC Transportation Planning Study indentified near- term and long- term transportation needs within SRPMIC. It provided an inventory of the transportation network, an evaluation of transportation needs, and documentation of a 20- year transportation plan that responds to both near-and long- term development scenarios. It also established priorities for implementation of the recommended improvements. This plan updates the 2001 Transportation Planning Study. Salt River Transit Five Year Plan, 2009 The Salt River Transit Five Year plan is a five- year implementation plan that provides the SRTS with a framework for meeting transit service needs in SRPMIC. The plan included Community goals for transit, a transit demand estimate, and strategies for coordinating with other transit services. This plan is also used for evaluating the SRTS for future Section 5311 Rural Public Transportation Program funding. Various Traffic Impact Studies SRPMIC Community Development Department provided copies of traffic impact analysis reports prepared for developments on the Pima Road commercial corridor. These studies were reviewed for socioeconomic and traffic data and road improvement recommendations. 2.2 Road Characteristics and Conditions This section presents the key physical and operating characteristics of major roads within SRPMIC. The key roads are described below: 11 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan North – South Routes Pima Road Pima Road runs north- south along the western boundary of the Community. The road serves as access to the Community’s commercial corridor and the City of Scottsdale. A Final Design Concept Report shows the completed corridor widening to its ultimate four- lane cross- section with two travel lanes in each direction. The City of Scottsdale maintains pavement, drainage and traffic signals on Pima Road. Pima Freeway ( L101) The Pima Freeway is an ADOT facility through SRPMIC east of Pima Road with three general purpose travel lanes and one High Occupancy Vehicle ( HOV) travel lane in each direction. The freeway serves as a vital part of the regional freeway system. This route provides access to both SRPMIC and the City of Scottsdale at nine ( 9) traffic interchanges listed below from south to north: • McKellips Road • McDowell Road • Thomas Road • Indian School Road • Chaparral Road • McDonald Drive • Indian Bend Road • Via de Ventura • Pima Road/ 90th Street 92nd Street 92nd Street runs across the west side of the Community, just east of the Pima Freeway. In addition to serving housing, the southern portion of the road provides access to the Casino Arizona and the Roadrunner Trailer Park, while the northern portion serves the Scottsdale Community College. The road has one travel lane in each direction. It is maintained by SRPMIC. Dobson Road Dobson Road runs across the west side of the Community. The southern portion of this route mainly serves housing and farming operations, while the northern portion serves Casino Arizona at Indian Bend and some commercial properties. It is maintained by SRPMIC and has one travel lane in each direction. Longmore Road Longmore Road runs across the west side of the Community between Dobson Road and Alma School Road. The route serves residential housing, farming operations, Talking Stick Golf Club, Vulcan Materials Gravel Pit, two churches, the Salt River Community Center, the Salt River Elementary School, the Salt River Ball Fields, and the west entrances of the Government Tribal Complex. It is maintained by SRPMIC and has one travel lane in each direction. Alma School Road Alma School Road runs across the west side of the Community. The route mainly serves housing and farming operations and the east entrances of the Government Tribal Complex. It provides two key bridge crossings: 1) Salt River, and 2) Arizona Canal. It provides a direct connection to Mesa and the Red Mountain Freeway. It is maintained by both MCDOT and SRPMIC and has two travel lanes in each direction from the 202 to McDowell ( MCDOT) and one travel lane from McDowell to McDonald ( SRPMIC). 12 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Country Club Drive Country Club Drive serves residential housing, agriculture, the Agate Steel Company, and provides the Community a connection to the State Route 87 ( Beeline Highway).

Road Lanes and Intersection Control Figure 3 shows total travel lanes for SRPMIC roads. It also shows the location of the 26 signalized intersections within the Community. 2.3 Road Functional Classification SRPMIC roads are classified under two separate functional classification systems: BIA2, and FHWA3 2 Bureau of Indian Affairs. ( October 21, 2004). Coding Guide and Instructions for IRR Inventory. Retrieved September 25, 2009, from BIA Web site, http:// www. doi. gov/ bia/ indianresroads/ irr_ coding_ guide. pdf . Functional classification is the grouping of highways, roads, and streets into classes based on mobility 14 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan and land access. In general, arterials provide greater mobility with less direct access to land, while local roads and collectors provide more access to land with less mobility. Functional classification also serves as a basis for establishing speed limits, parking restrictions, design standards and access controls. A principal arterial, for example, typically provides mobility for longer distance trips with higher speeds and less access to adjoining properties. Conversely, the function of a local street is to provide direct access to neighborhoods at lower speeds. Figure 4 shows the existing BIA road functional classification for Community roads. Appendix C includes a description of BIA functional classification. Figure 4 also shows the Community roads with an FHWA functional classification, which makes them eligible for federal funding. Appendix C also includes a map showing the 2009 FHWA Phoenix- Mesa Urban Area Functionally Classified Roads. The FHWA functional classification definitions are described below: Principal Arterial: This facility serves regional circulation needs. It moves traffic at moderate speeds while providing limited access to adjacent land. Access is controlled through raised medians and through spacing and location of driveways and intersections. Minor Arterial: This facility is generally a four- lane and sometimes a two- lane road. Its purpose is to serve regional/ sub- regional traffic circulation needs by moving traffic at moderate speeds while providing limited access to adjacent land. Major Collector: This facility provides for shorter distance trips, generally less than three miles, and primarily serves to collect and distribute traffic between key traffic generators, local streets and arterial streets. This classification provides direct access to abutting land. Urban Collector: Urban Collectors serve shorter distance trips than the Major Collector ( generally less than one mile). They provide direct access to adjacent land and collect and distribute traffic between key traffic generators, local streets and arterial streets. Local Street: Local Streets provide direct access to adjacent land and distribute traffic to collector facilities. Urban and Rural Areas FHWA designates roads as urban or rural depending on the type of area served. Urban and rural areas have different characteristics, such as density, types of land use, density of street and highway networks and the nature of travel patterns. Typically, an urban area has a population of 5,000 or more and is designated by the U. S. Census Bureau. Rural areas are the areas outside of the boundaries of urbanized areas. 3 Federal Highway Administration. ( 1989). FHWA Functional Classification Guidelines.

There are six levels of service defined by the Transportation Research Boards’ Highway Capacity Manual 2000 ( HCM), published by the Transportation Research Board ( TRB). Each level of service is given a letter designation from A to F, with A representing the optimal or best condition and F the worst Roadway segment level of service is characterized by the HCM as follows: LOS A: Best, free flow operations ( on uninterrupted flow facilities) and very low delay ( on interrupted flow facilities). Freedom to select desired speeds and to maneuver within traffic is extremely high. LOS B: Flow is stable, but presence of other users is noticeable. Freedom to select desired speeds is relatively unaffected, but there is a slight decline in the freedom to maneuver within traffic. LOS C: Flow is stable, but the operation of users is becoming affected by the presence of other users. Maneuvering within traffic requires substantial vigilance on the part of the user. LOS D: High density but stable flow. Speed and freedom to maneuver are severely restricted. The driver is experiencing a generally poor level of comfort and convenience. LOS E: Flow is at or near capacity. All speeds are reduced to a low, but relatively uniform value. Freedom to maneuver within traffic is extremely difficult. Comfort and convenience levels are extremely poor. LOS F: Worse, facility has failed, or a breakdown has occurred. LOS A, B, and C are generally considered to be satisfactory service levels, while the influence of congestion becomes more noticeable at LOS D. LOS E is undesirable and is considered by most agencies to be the limit of acceptable delay, and LOS F conditions are considered to be unacceptable to most drivers. Most jurisdictions strive to attain a LOS of at least D or better on all roads and signalized intersections in urban areas, and LOS C is targeted for rural conditions. LOS Analysis Methodology Two types of level of service analysis were used to evaluate current traffic operation conditions on SRPMIC. The first is a generalized segment level of service analysis. This approach utilizes a lookup table that provides level of service volume thresholds by functional classification and number of through travel lanes. This lookup table, Summary of Generalized Annual Average Daily Volumes for the Phoenix Urban Area, was prepared by MAG for transportation planning studies. The volume thresholds in this table, shown in Appendix D, are based on Phoenix daily traffic characteristics and the HCM. Secondly, level of service analysis for signalized intersections was conducted for intersections in the Pima Road commercial corridor. A traffic microsimulation model was developed for weekday AM and PM peak hours for 32 intersections in the Pima Freeway corridor. Segment LOS Analysis The IRR System Inventory provides average daily traffic ( ADT) for many of the Community roads. The IRR inventory used count data from 2006, 2007 and 2008. These daily traffic counts together with generalized segment level of service thresholds are shown in Figure 5. 18 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan SYNCHRO Model SYNCHRO is transportation operations analysis software prepared by Trafficware. It uses methods described in the HCM to evaluate traffic operations on road systems. It is widely used by traffic engineers for both signalized and non- signalized intersection operations analysis. Peak hour traffic volumes and peak hour factors, intersection lane configurations obtained during site visits, traffic control parameters, and free flow speeds were coded into the SYNCHRO models. A SYNCHRO model was developed for the Pima Road corridor to support the Pima Road Design Concept Report. The HDR study team built on this existing effort and expanded it to include 35 intersections in the Pima Freeway Corridor. This includes all Pima Freeway signalized intersections within the Community. The model also includes intersections on Dobson Road and 92nd Street. The purpose of this Pima Freeway corridor SYNCHRO model is to provide intersection- level traffic operations analysis for both existing and future conditions. This analysis will provide information about the need for installing new traffic signals and the intersection lane configuration needed to accommodate future travel demand. The City of Scottsdale and ADOT provided 2009 signal timing data for the signalized intersections. The study team reviewed a number of studies, including several traffic impact analysis reports and the July 2009 Pima Road traffic analysis report for the DCR, to identify recent traffic counts to support model development. Intersection turning movement counts were conducted in September 2009 for Pima Freeway corridor intersections at locations where no recent traffic data could be identified. The location of the 35 study intersections in the Pima Freeway corridor is shown in Figure 6. Appendix E shows the study intersections’ 2009 lane configuration and traffic control and the 2009 AM and PM peak hour traffic volumes and level of service.

The data provided by ADOT includes incident date and time, crash location, crash severity, crash type, collision manner, environmental conditions, and crash causes. Additional analysis was conducted on the crash information obtained from SRPMIC Police Department ( SRPMIC PD) for the period from January 1, 2005 through July 16, 2009. The data provided by SRPMIC PD contained information about crash location, crash severity, and time and date. The analysis was done to identify potential safety hazards contributing to motor vehicle crashes within the Community and suggest measures to improve safety for motor vehicles and pedestrians. As part of the analysis, a meeting with personnel from SRPMIC PD and a field review was conducted on July 20, 2009. There were 858 crashes reported in the ADOT database and 3,694 crashes in the data provided by SRPMIC PD. It was found that 484 of the crashes reported in SRPMIC PD database were also reported in the ADOT database. The crash analysis presented in the following sections thus analyzed 858 crashes in the ADOT database and 3,210 additional crashes in the SRPMIC PD database. ADOT Data A total of 858 crashes were reported by ADOT within the study area during the five year analysis period. The ADOT data for 2004 and 2005 appears to be incomplete. These years show less than half of the crashes reported in 2003 and 2006. During the study period, 60 percent of the reported crashes occurred at the intersections, while 37 percent occurred at mid- block locations and driveway access points. Table 1 shows the crashes by location and percentage. Crashes occurring within 250- feet radius of an intersection were treated as intersection crashes. Crashes at mid- block locations occurred along roadway sections, at driveway access and alleys.

Notes: a) Rank based on crashes in ADOT database. b) ADOT crashes with SRPMIC PD crashes in parentheses. Nine of the ten top ranked high crash intersection locations are the same in both the ADOT and SRPMIC PD databases. The exceptions are the McKellips Road- Alma School Road intersection in the ADOT list and SR 87- Gilbert Road intersection in the SRPMIC PD list. Furthermore, SRPMIC PD has indicated that the intersections of McKellips Road- Dobson Road and Via de Ventura- Dobson Road are other high crash intersections. To understand the different crash characteristics at these high crash locations, crash type and crash rates were analyzed at each location. Table 7 below summarizes the high crash locations from the ADOT database with crash rates and crash types. SRPMIC PD data does not have information on crash types and therefore, are not analyzed. 32 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 7 Crash Types and Crash Rates at High Crash Intersections ( ADOT Data) Location # of Crashes Angle Rear End Sideswipe Single Vehicle Other Pima Freeway- Chaparral Road 63 47 ( 75%) 11 ( 17%) 1 ( 2%) 2 ( 3%) 2 ( 3%) Pima Freeway- McKellips Road 63 36 ( 57%) 19 ( 30%) 3 ( 5%) 3 ( 5%) 2 ( 3%) Pima Freeway- McDowell Road 38 18 ( 47%) 11 ( 29%) 3 ( 8%) 6 ( 16%) 0 ( 0%) Pima Freeway- Indian School Road 32 12 ( 38%) 10 ( 31%) 3 ( 9%) 6 ( 19%) 1 ( 3%) Pima Freeway- Indian Bend Road 27 17 ( 63%) 6 ( 22%) 4 ( 15%) 0 ( 0%) 0 ( 0%) Pima Freeway- Thomas Road 23 10 ( 44%) 7 ( 30%) 4 ( 17%) 2 ( 9%) 0 ( 0%) McKellips Road- Alma School Road 18 7 ( 39%) 8 ( 43%) 1 ( 6%) 1 ( 6%) 1 ( 6%) Thomas Road- Pima Road 15 12 ( 80%) 3 ( 20%) 0 ( 0%) 0 ( 0%) 0 ( 0%) Pima Freeway- 90th Street 14 5 ( 36%) 7 ( 50%) 1 ( 7%) 0 ( 0%) 1 ( 7%) Pima Road- Chaparral Road 13 7 ( 53%) 4 ( 31%) 1 ( 8%) 1 ( 8%) 0 ( 0%) Source: ADOT Traffic Safety Division, data from June 1, 2003 to May 31, 2008 ( July 2009).

Figure 12 shows the fatal crash locations in the study area. The McKellips Road and Dobson Road intersection has the highest number of fatal crashes with four. There were two fatal crashes at each of the following intersections of McKellips Road- Pima Freeway, McKellips Road- Alma School Road and SR 87- McDowell Road. Pedestrian- Bicycle Crash Locations There were 13 pedestrian and bicycle crashes in the study area during the analysis period from June 1, 2003 to May 31, 2008 per ADOT data. Figure 12 shows the pedestrian and bicycle crash locations in the study area. As shown in the figure, a majority of pedestrian crashes occurred along McKellips Road and Alma School Road. Crash Observations at High Crash Intersections Based on evaluation of the crash data, interviews with SRPMIC PD, and field observations, the HDR study team reviewed conditions at the high crash intersections and identified near- term corrective measures to mitigate potential safety hazards. This section first discusses the intersection conditions and then addresses potential corrective measures. Pima Freeway- Chaparral Road There were a total of 63 crashes reported at this intersection in the ADOT database over the five year analysis period between June 1, 2003 and May 31, 2008.

Some of the potential corrective measures that can be made to reduce these types of crashes occurring at intersections include: a) Install a raised median on Chaparral Road between the Pima Freeway traffic interchange and Pima Road. b) Install Recessed Pavement Markers ( RPM) along lane markings, rumble strips along edge lines of the roadway to obtain driver attention. c) Flexible reflective delineators and lighted flexible boulder signs should be considered along painted island curbs at tight left turn movements to obtain driver attention. d) Optically programmed signal heads should be considered for eastbound and westbound traffic at Thomas Road- Pima Road and Thomas Road- Pima Freeway traffic interchange. e) A modern roundabout could be an alternative for an intersection with history of crashes due to left turns and higher speeds. It would also serve as a traffic calming measure. 37 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.8 Public Transit Salt River Transit Public transportation serves a variety of functions for the SRPMIC. It gives mobility to persons without access to an automobile and to those who do not drive and it provides important links between rural communities and metropolitan areas. According to the 2000 Census, 13 percent of SRPMIC households had no vehicle available, one- third of the Community is under 18 years of age, and an additional 12 percent are over 65 years of age. The Salt River Pima- Maricopa Indian Community Transit System ( SRTS) provides dial- a- ride services for tribal residents traveling to Mesa, Tempe, and Scottsdale for shopping, employment, medical and social services. Salt River Transit has been providing transit services to Community members since 1983. The mission statement of the SRTS is: “ The transit system provides safe and efficient transportation service to residents, tribal employees and the general public to the SRPMIC. Our primary purpose and continued goal is to provide service and assistance to residents in reaching destinations such as medical facilities, employment centers, education facilities, shopping centers and other areas.” Review of summary ridership information provided by the Community shows that ridership numbers are stable with little monthly fluctuation. Community staff reported there is a noticeable drop in ridership when quarterly benefit checks are received, but levels quickly adjust back to baseline. Existing Service Route Descriptions The current service routes have been developed over time addressing the needs of the Community members, resulting in a rider base that is stable and predictable. Figure 13 shows their areas of coverage and the surrounding Valley Metro Transit service. Table 9 describes the service routes.

As can be seen in Figure 13, the service area boundaries of the current routes cover most of the areas of residential and commercial development within the Community ( with the notable exception of the commercial development north of Indian Bend Road). The service areas extend beyond the Community boundaries to provide transportation to important destinations for Community members including Scottsdale Healthcare and regional shopping centers. Important destinations identified by SRTS staff include the following ( in no particular order): • Fiesta Mall, Mesa • Sycamore/ Main Street Light Rail Transit Stop, Mesa • Riverview Mall, Mesa • Fry's Food Store 77th Street and E McDowell Road, Scottsdale • Pavilions, Indian Bend and Pima Freeway, Scottsdale • Scottsdale Healthcare, Scottsdale • SRPMIC Tribal Complex • Casino Arizona, McKellips • Scottsdale Community College, Chaparral 40 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Transfer points for SRTS to Valley Metro routes include: • McDowell and Granite Reef Road ( Valley Metro Route 17, McDowell Road) • Hayden and Thomas ( Valley Metro Route 29, Thomas Road) • Scottsdale Community College ( Valley Metro Route 50, Camelback Road; and 76, Miller Road • Country Club Drive and McKellips ( Valley Metro Route 112, Country Club Drive/ Arizona Avenue) • The Pavilions The SRPMIC Department of Transportation director has been in contact with Valley Metro staff to discuss the opportunity for the extension of Valley Metro service to the Tribal Headquarters at Longmore and Osborne. SRTS trips beyond the Community could transfer to Valley Metro from these locations. Current economic conditions have delayed action on this, but interest exists to continue to explore this option. Transit Planning In 2009 ADOT prepared the Salt River Transit Five Year Plan ( Transit Plan). This Plan, prepared in support of the 5311 funding received from ADOT, identifies the Community’s goals for transit, transit demand, and a five- year implementation plan. The plans provide a five- year ‘ road map’ to address the transportation needs and coordination of public transportation and specialized transportation services for the elderly and disabled in the regions. In addition, they address the most efficient and effective management and funding programs for public transportation. These plans include an assessment of local transit needs within a five- year “ horizon,” achievable coordination and consolidation opportunities and a significant public involvement process. As part of the Transit Plan a rider survey was conducted in November 2008. The survey found that the primary trip purpose of riders is employment ( 35 percent), followed by education ( 20 percent) and medical purposes ( 17 percent). The survey found that all respondents would like to see weekend service and many asked that weekday service be extended to 7 p. m. Eighty- five percent of the riders ride Monday- Friday. This finding was confirmed by comments during outreach with a Tribal Council district meeting that suggested an extension of service to 9 or 10 p. m. The Transit Plan also assessed the transit dependent population within the Community, based on the work done in ADOT’s Arizona Rural Transit Needs Study ( May 2008). This study determined transit dependent populations and demand by County for the entire state based upon the Arkansas Public Transportation Needs Assessment ( APTNA) method4 Transit Funding . The Transit Plan estimated the transit dependent population within the Community, using SRPMIC’s population relative to the total rural Maricopa County population. For this study, we have evaluated the transit dependent population by direct application of the 2000 Census data. Funding for rural transit services comes from several sources: the Federal Transit Administration ( FTA) Section 5311 Rural Transportation funds and the SRPMIC. For the 2009 operating year, approximately 60 percent funding came from Section 5311 grant funding with the remaining 40 percent coming directly from the SRPMIC. 4 The Arkansas Public Transportation Needs Assessment ( APTNA) method represents the demand for transit service by applying trip rates to three population groups: elderly persons ages 60 and over, persons with disabilities under age 60, and persons living in poverty under age 60. 41 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan The current fare structure for each one- way trip is shown in Table 10. Although the fares are relatively low in comparison to other rural transit providers, there is a strong commitment to maintaining an inexpensive transportation option for Community members. Table 10 SRPMIC Fare Structure One- Way Trip Fares General Seniors/ Disabled Within the Community $. 75 $. 25 Outside the community $. 85 $. 50 Source: Salt River Pima- Maricopa Indian Community Transportation Department, Transit Division ( 2009). Rural Public Transportation Program ( Section 5311) The Section 5311 Rural Public Transportation Program provides capital, administrative and operating assistance for public transportation programs in rural and small urban areas. FTA Section 5311 funding supports capital expenditures, operating expenses, and administrative expenses. A local match is required with the amount varying by program. They may be used for general public transit services in rural areas ( those areas with less than 50,000 in population). The FTA apportionment funding is allocated to states on a population- based formula. The ADOT Multimodal Planning Division awards the funds to participating systems through an annual competitive application process and acts as administrator for the 5311 program. Besides the SRPMIC, the Hopi Tribe and Navajo Nation are the only tribes in Arizona currently receiving Section 5311 grant funding. Recommendations from ADOT’s 5- year plan focus on five key areas: 1) management structure and administration, 2) effectiveness of service, 3) marketing, 4) coordination ( both locally and within the region), and capital planning. The reader may refer to that plan, on file with the Transit Department, for specifics and recommendations. Operations Information The SRTS fleet currently includes nine vehicles: ( 3) 14 Foot Passenger Vans, ( 1) 13 Foot Passenger Van, and, ( 5) 11 Foot Passenger Vans. These vehicles were all purchased with Community funds. Table 11 shows SRTS service data for Fiscal Year 2008.

Transit Dependent Populations For the vast majority of trips produced and/ or attracted in the SRPMIC area, there are few viable alternatives to the automobile. Segregation of land uses and nearly universal automobile availability has resulted in dispersed land uses that are difficult to reach without an automobile, as well as little or no alternate modes of travel. Not only is there little public transportation service available, the distances between origin and destination and lack of facilities for pedestrians and bicyclists makes walking or riding a bicycle impractical and/ or unsafe. In most cases, about the only viable alternative to driving somewhere is riding there with someone else. Transit Demand Using the APTNA, populations of elderly persons age 60 and over, persons with disability under the age of 60, and persons living in poverty under age 60 are considered transit dependent populations. Within the SRPMIC Community an assessment of these populations indicates that as much as 60 percent of the population would be considered transit dependent5 To determine the potential demand for transit services, the APTNA assessed trip rates based on Census information, which was reported as an annual trip rate for each group. The findings are reported in . Table 13. 5 This is based on Census 2000 information for the SRPMIC which reveals 16 percent of the population is over age 60; 28 percent of the population under 65 is in poverty; and an additional 19 percent of the age 5 to 65 population has a disability. Adjusting for the population of the last two groups over 60, the resulting transit dependent population is equivalent to 60 percent of the Community’s population. 43 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 13 Annual Transit Trip Rates for Select Demographic Groups Demographic Group Trip Rates: Annual One- Way Passenger Trips Elderly persons Age 60 and Over 6.79 Persons with Disability Under Age 60 4.49 Persons living in Poverty Under Age 60 20.5 Source: Salt River Transit Five- Year Plan, January 2009. Using these trip rates, it was determined that the 2009 transit demand estimate for the SRPMIC Community is 48,377. When compared to the 22,419 annual passenger trips recorded in 2008, this estimate represents an additional 26,000 trips ( 116 percent additional annual trips) of current unmet transit demand. 44 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.9 Non- Motorized Transportation Today, there are few paved or un- paved trails within the SRPMIC. The rural character of the Community, characterized by its narrow roads with no curb or gutter, requires pedestrians to walk along edge of pavement and in some cases where obstructions or canal laterals exist, pedestrians have to walk on the pavement. Sidewalks are present only in some of the newer developments, subdivisions within the People’s Village, around some of the commercial development in the Pima Freeway corridor and at the Government Complex. Even with the sidewalks in place adjacent to some of the denser subdivisions, there is little connectivity with schools or activity centers. The 2006 SRPMIC General Plan includes a number of objectives and implementation measures addressing the need for improved pedestrian connectivity. Figure 14 shows the Salt River Elementary School, one of the few locations with sidewalks. Figure 14 Salt River Elementary School Sidewalks The General Plan identifies the creation of a trails master plan to connect activity areas for pedestrians, bicyclists, and equestrians within the Community as one of the Actions/ Implementation Measures ( IM 24, SRPMIC General Plan, 2006). 45 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 3.0 Land Use and Socioeconomic Conditions This section provides an overview of the existing land use together with estimates of SRPMIC population and employment. The demographic information used in this analysis is from the 2000 Census. While this information is nearly ten years old, the 2000 Census remains the most comprehensive source of demographic data available. When appropriate and available, other more recent socioeconomic information is cited. Demographic information is important in developing a profile of the Community’s residents and households. A comparative analysis with data from the county and state is included to illustrate how SRPMIC relates to the greater metropolitan area and state. 3.1 Title VI and Environmental Justice The Environmental Protection Agency and FHWA define environmental justice as the “ fair treatment for people of all races, cultures, and incomes, regarding the development of environmental laws, regulations, and policies.” Environmental justice principles and procedures are followed to improve all levels of transportation decision making. Title VI of the Civil Rights Act of 1964 prohibits discrimination on the basis of race, color, or national origin. The 1994 Executive Order 12898 on environmental justice addresses minority and low- income populations. The rights of women, the elderly, and the disabled are protected under related statutes. These Presidential Executive Orders and other related statutes fall under the umbrella of Title VI. There are three fundamental environmental justice principles applicable to the transportation project development process: • to avoid, minimize, or mitigate disproportionately high and adverse human health and environmental effects, including social and economic effects, on minority populations and low- income populations • to ensure the full and fair participation by all potentially affected communities in the transportation decision- making process • to prevent the denial of, reduction in, or significant delay in the receipt of benefits by minority and low- income populations Effective transportation decision making depends on understanding and properly addressing the unique needs of different socioeconomic groups. Properly implemented, environmental justice principles and procedures improve all levels of transportation decision making. The five minority groups addressed by Title VI and Executive Order 12898, Environmental Justice, are: • Black ( a person having origins in any of the black racial groups of Africa) • Hispanic ( a person of Mexican, Puerto Rican, Cuban, Central or South American, or other Spanish culture or origin, regardless of race) • Asian American ( a person having origins in any of the original peoples of the Far East, Southeast Asia, the Indian subcontinent, or the Pacific Islands) • American Indian and Alaskan Native ( a person having origins in any of the original people of North America and who maintains cultural identification through tribal affiliation or community recognition) • Some other race, or persons of more than one race 46 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan A member of the low- income population is defined as “ a person whose household income is at or below the Department of Health and Human Services poverty guidelines.” The Department of Health and Human Services poverty guidelines state that the poverty level for a family of four in 2009 is $ 22,050 ( note, however, that this income level cannot be compared directly with current income levels because the value of money changes year to year). Other protected populations include concentrations of elderly, the disabled and female heads of households. These populations for the SRPMIC Community, Maricopa County and Arizona are shown in Table 14. Table 14 Title VI and Environmental Justice Population Percentages, SRPMIC, Maricopa County and Arizona Category Arizona Maricopa County SRPMIC Minority 36.2% 33.8% 82.5% Hispanic or Latino 25.3% 24.8% 16.9% Black or African American 2.8% 3.5% 0.4% American Indian or Alaskan Native 4.5% 1.5% 45.6% Asian 1.7% 2.1% 0.1% Native Hawaiian or Other Pacific Islander 0.1% 0.1% < 0.1% Some Other Race 0.1% 0.1% 10.6% More than One Race 1.6% 1.7% 8.8% Persons Living Below the Poverty Level 13.9% 11.7% 30.5% Disabled 19.3% 18.0% 27.7% Age 65 and Older 13.0% 11.7% 12.5% Female Heads of Household 6.8% 6.6% 14.1% Source: Census 2000 Redistricting Data ( PL94- 171) Summary File. The protected populations considered in this analysis are described below: • Minority populations include people who identify themselves as Hispanic or Latino, Black or African American, American Indian and Alaskan Native, Asian, Native Hawaiian and Other Pacific Islander, persons of some other race, or persons of more than one race. • Low- income populations include people living in households with an income at or below the U. S. Department of Health and Human Services poverty guidelines. Low- income populations may have greater difficulty locating replacement housing in the area. They may rely on public services and facilities, such as public transit and public recreational amenities, to a greater extent than the general population. • Elderly populations consist of people who are age 65 and older. While elderly citizens often drive, the National Highway Traffic Safety Administration ( NHTSA) reports that both high-speed and high- traffic routes may present a problem for some ( NHTSA, 2007). In addition, the elderly may have a need for transit service or may opt to use transit if it is offered. • Disabled populations are civilian, non- institutionalized persons aged 5 and over with disabilities ( such as sensory, physical, mental, self- care, going outside of home, and 47 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan employment disabilities). • Female head- of- household populations consist of households headed by a female with no husband present and with her own children under the age of 18. These households tend to have lower incomes than households headed by married couples or a single man and oftentimes have a greater need for affordable housing. Poverty is a major concern of the Salt River Pima- Maricopa Indian Community with the median per capita income of $ 9,592 ( more than 56 percent below the national per capita income of $ 22,000). The percentage of the population in poverty is 30.5 percent, more than twice that of the overall state poverty level of 14 percent. 3.2 Existing and Planned Land Use The Community is rural in character with over 90 percent of the area classified as either open space or vacant. Commercial and industrial development is limited to the periphery of the Community along major transportation corridors. The Community encompasses approximately 85 square miles ( 54,632 acres), with 19,000 held as a natural preserve and approximately 17,000 acres under cultivation in a variety of crops including cotton, melons, potatoes, onions, broccoli and carrots.

The SRPMIC General Plan Land Use Map shown in Figure 15 identifies 11 planned land use designations and two special area designations for the Pima Freeway corridor and the People’s Village. The Pima Freeway corridor is the Community’s economic growth area. It extends north- south along the Pima Freeway from McKellips Road to the Community’s northern boundary. The People’s Village, located in the heart of the Community, is intended to be a Community- oriented focal point of activity. 48 Salt River Pima- Maricopa Indian Community Transportation Planning Study Figure 15 2006 General Plan Land Use Map 49 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 3.3 Traffic Analysis Zones Traffic analysis zones ( TAZ) are geographic areas generally bounded by roads, railroads, major watercourses or other easily identifiable physical features. SRPMIC socioeconomic data is tabulated by TAZ geography. Using the City of Scottsdale Travel Demand Model ( STDM), traffic is generated by each land use within the TAZ, distributed, and then assigned to the roadway network. Subsequently, using projected land use data, future traffic forecasts can be derived. 3.4 Population It is estimated that approximately 7,188 of the Communities 8,976 members live on the reservation6 The median age of the SRPMIC population is 28.3, compared with 34.2 for Arizona. Much of the population is young with 39.7 percent of the population under 20 years of age. For Arizona as a whole, 29.7 percent of the population is under 20 years of age. This is important information because age helps dictate transportation mode choice and walking rates are drastically higher for younger age groups than older ones. The 5– 15 year old age group has almost twice the percentage of walking trips as the 40– 64 year old age group . The U. S. Census reported a 2000 population of 6,405. Many members live on scattered home- sites largely located south of the Arizona Canal, which essentially bisects the Community east- west; in the Lehi area, located south of the Salt River; and in the People’s Village, a two and one- quarter square mile area that is developing as a focal point of activity for Community members. 7 The average household size in the Community is 3.24 persons per household, 20 percent higher than that of Maricopa County ( average household size is 2.67; slightly higher than Arizona as a whole, which is 2.64). . Figure 16 shows the estimated 2006 SRPMIC population density by TAZ. 6 The reported population of 8,976 members is from the Salt River Pima- Maricopa Indian Community’s Enrollment Office. The 2009 population estimate is extrapolated from the 2000 Census population and the Maricopa Association of Governments’ 2007 socioeconomic projections. 7 Pucher, J. and Renne, J. ( 2003).

This figure of nearly 23 percent vacant is more often seen in communities with a high percentage of second or vacation homes. SRPMIC staff and census data indicate that this higher vacancy rate is attributable to the Shadow Mountain Village and Roadrunner Lake Resort mobile home parks that lease land from the Community. Primarily non- SRPMIC members live in the mobile home parks. On the other hand, the home ownership rate for the SRPMIC is over 80 percent, significantly higher than the 68 percent for Maricopa County or the state as a whole. Table 17 shows a comparison of key housing statistics for SRPMIC, Maricopa County, and Arizona. Table 17 Occupied Housing Description SRPMIC Maricopa County Arizona Occupied Housing Units 77.6% 90.6% 86.9% Owner- occupied Housing Units 80.4% 67.5% 68.0% Renter- occupied Housing Units 19.6% 32.5% 32.0% Average Household Size of Owner- occupied Units 3.04 2.74 2.69 Average Household Size of Renter- occupied Units 4.09 2.54 2.53 Source: 2000 US Census; Salt River Pima- Maricopa Indian Community General Plan Update Existing Conditions Report, September 2003. 3.7 Interim and Planning Horizon Population and Employment Projections Table 18 shows that between the 1990 and 2000 censuses SRPMIC grew 31 percent. During the same ten- year period, Maricopa County grew over 45 percent. Generally consistent with its growth in the previous decade, Maricopa County grew nearly 20 percent between 2000 and 2005. However, the MAG Socioeconomic Projections of Population, Housing, and Employment by Municipal Planning Area and Regional Analysis Zone, May 2007, show that SRPMIC grew by only seven percent over the same five- year period. While Maricopa County continued to grow at more than 3 percent annually, the rate of growth in the SRPMIC slowed in relation to the county as a whole between 2000 and 2005. 54 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 18 Historic Population Growth Description 1990a 2000b 2005c POPd HHe POPd HHe POPd HHe Maricopa County 2,122,101 807,560 3,072,366 1,132,886 3,616,690 1,352,967 SRPMIC 4,852 1,583 6,355 1,959 6,742 2,056 Source: HDR Engineering, Inc., September 2010.

General Plan Land Use Considerations Although more than 83 percent of SRPMIC is open space, there is a shortage of land for new residential development. This is largely due to the allotment system of land ownership across the Community. Cooperation of multiple landowners is required to assemble a parcel large enough for a subdivision. This makes large- scale residential developments challenging. Additionally, it is difficult for Community members who are not landholders to buy and develop land in the Community. One of the goals of the SRPMIC General Plan is to promote residential development to accommodate the housing needs of Community members. This development effort is focused on the People’s Village and includes such subdivisions as “ Victory Acres” and “ Canalside”, located south of the Arizona Canal between Country Club Drive and Mesa Drive. These subdivisions were formed from existing tribally owned lands set aside for Community purposes. With the completion of the latest Canalside subdivision, there are additional 91 parcels available for development. While there is a shortfall of land for new residential development, the SRPMIC General Plan designates eight percent of its land area, or over 4,500 acres, for mixed- use commercial development. This is located primarily along the Pima Freeway Corridor. Currently the corridor contains two Casino Arizona locations, golf courses, and retail and commercial office development. A new convention center and hotel opened in 2010. A spring training facility is under construction and due to open in early 2011. In addition to the new hospitality and sports developments, commercial and retail development along Pima Road is also growing. Wal- Mart is currently expanding at its location on Chaparral Road. New office buildings in Pima Center and Riverwalk are permitted or under construction. Population Projections Recent MAG estimates show SRPMIC population growth slowing. Between 2005 and 2030 MAG estimates that the Community will grow by 0.34 percent annually. This is well below the 2.8 percent annual growth recorded between 1990 and 2000. In large part, population growth is limited by the availability of land for residential development. As noted earlier, the SRPMIC Housing Department is completing Canalside III and IV with 91 new home sites for Community members. It is located along the Arizona Canal in the People’s Village between Mesa Drive and Country Club Drive. Build out of the Canalside home sites is assumed by 2030. The Community is also planning a multifamily village development on the northwest corner of Chaparral Drive and Dobson Road; an area shown as a high density residential development in the SRPMIC 55 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan General Plan. Build out of the multifamily village, which is anticipated to occur by 2030, will provide between 220 and 240 new residences. The Housing Department is also considering new subdivisions on Country Club Drive and Center Street between Indian School Road and Camelback Road. The size and timing of these subdivisions is unknown. Currently, SRPMIC leases land to two mobile home parks: Shadow Mountain Village is located north of McKellips Road west of the Pima Freeway; and, the Roadrunner Lake Resort is located on 92nd Street north of McKellips Road. Residents of Shadow Mountain Village and Roadrunner Lake Resort are predominately older non- SRPMIC members. The demographics of these mobile home parks show a larger number of seasonal homes and smaller household sizes that change the picture of the SRPMIC demographics. Census 2000 data for overall SRPMIC shows that 77 percent of housing units were occupied. Average household size was 3.24 persons per household. However, SRPMIC Housing Department officials describe long waiting lists for Community housing with high occupancy rates. Without Shadow Mountain Village and the Roadrunner Lake Resort, Census 2000 data reflects the tight demand for Community housing with occupancy rates over 95 percent. Average household size is 4.21 persons per household. The leases for both mobile home parks are set to expire by 2030. The Shadow Mountain Village lease will expire in 2027. The Roadrunner Lake Resort lease will expire in 2019. SRPMIC plans to include the areas in its commercial and retail redevelopment plans. The eventual closure of the mobile home parks will mean a loss of population for SRPMIC because most of the mobile home park residents are not Community members. Only Community members and their families are allowed to live on SRPMIC. The 2030 population projections for this study are based on the following: • Full buildout and occupancy of the 331 planned new Canalside and the multifamily village residences. • Population lost from the closure of the Roadrunner Lake Resort in 2019 will be replaced by Community members living on new home sites in allotted lands. • Since Shadow Mountain Village will remain in place through most of this study’s planning horizon, its population is included in the 2030 projections. • Average household size estimated at traffic analysis zone ( TAZ) level based on Census 2000. Table 19 shows the population projections. Figure 18 shows the 2030 population distribution by TAZ. The thematic map colors represent population per square mile. The labels show the population projection by TAZ. Population projections for the interim planning horizons of 2015 and 2020 are interpolated values. 56 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 19 SRPMIC Population Projections Description Year 2009 2015 2020 2030b Households 2,219 2,303 2,373 2,510 Populationa 7,188 7,690 8,100 8,900 Source: HDR Engineering, September 2010.

The PARA program is funded through the Federal Highway Administration’s ( FHWA) State Planning and Research program to non- metropolitan communities for the purpose of conducting transportation planning studies. PARA funds may be applied to address a broad range of planning issues related to road and non- motorized transportation modes. 1.1 Study Area Characteristics The Salt River Pima- Maricopa Indian Community is a sovereign tribe located on the east side of the Phoenix metropolitan area. It is bordered by the cities of Mesa and Tempe to the south, Scottsdale to the west and north, the town of Fountain Hills and the Fort McDowell Indian Reservation to the north, and unincorporated Maricopa County and Tonto National Forest to the east. The Community is a member of the Maricopa Association of Governments ( MAG), the municipal and intergovernmental planning organization for Maricopa County and the metropolitan Phoenix area. The study area for this LRTP is the SRPMIC itself. While Mesa, Tempe, Scottsdale, Fountain Hills, and Maricopa County were stakeholders in this planning study, the study area did not include land owned by any of these jurisdictions. Figure 1 shows SRPMIC in its regional context. Figure 2 shows the SRPMIC Long Range Transportation Planning Study Area. The Community is comprised of two Native American tribes with two distinct backgrounds and cultures: the Pima, " Akimel O'Odham" ( River People) and the Maricopa, " Xalychidom Piipaash" ( people who live toward the water). Although these tribes are distinct, the Community is considered in its entirety for this long range transportation planning study. SRPMIC encompasses approximately 85 square miles ( 54,632 acres), with 19,000 held as a natural open space preserve located primarily in the eastern portion of the Community. Elevations are higher in the open space preserve and the topography of the Sonoran Desert landscape is anchored by Red Mountain and Saddleback Mountain. The Verde River meets the Salt River east of Red Mountain. Many sensitive cultural sites are located across this open space preserve. The Central Arizona Project Canal traverses this preserve area. The Beeline Highway ( SR 87) cuts through this area providing a connection between Mesa and Payson. The Salt River runs along the southern edge of the Community, separating the Lehi area from the rest of the Community. Sand and gravel mining operations are located along the lower portions of the Salt River. The upper Salt River also serves as a barrier between the Community and the Tonto National Forest. Moving westward across the Community, the landscape transitions from open space preserve to agriculture. There are approximately 17,000 acres under cultivation in a variety of crops including cotton, melons, potatoes, onions, broccoli and carrots. Scattered residences are located in the agricultural area, primarily along the road grid. Irrigation water is pumped from 87 17 10 MARICOPA COUNTY 10 51 101 202 202 88 60 87 74 PINAL COUNTY Scottsdale Phoenix Mesa Tempe Glendale Fountain Hills Apache Junction Fort McDowell Indian Res.

The People’s Village with schools and housing is located at the center of the Community. The western portion of the Community is the interface between the rural Community and the urban centers of Scottsdale, Tempe, and Mesa. The Pima Freeway ( L101) runs north- south along the western edge. Two Community casinos are located in this area – one at Indian Bend Road, the other at McKellips Road. The Pima Road corridor is the Community’s commercial and industrial development area. The Community is building a Major League Baseball spring training facility on Pima Road between Indian Bend Road and Via de Ventura. 1.2 Indian Reservation Roads Program This LRTP meets an Indian Reservation Roads ( IRR) Program requirement. The IRR Program addresses transportation needs of tribes by providing funds for planning, design, construction, and maintenance activities. The program is jointly administered by the FHWA’s Federals Lands Highway ( FLH) Office and the Bureau of Indian Affairs ( BIA) in accordance with an interagency agreement. It provides guidance to tribes and tribal organizations for planning, designing, constructing and maintaining transportation facilities. It also establishes a funding distribution methodology to allocate funds based on the relative needs of tribal communities for transportation assistance. The BIA established final rules for the Indian Reservation Roads Program in the Federal Register Volume 69, No. 137, Monday July 19, 2004. The Indian Reservation Roads are public roads that provide access to and within Indian reservations, Indian trust land, restricted Indian land, and Alaska native villages. IRR funds can be used for any type of federal Title 231 IRR Requirements transportation project providing access to or within Federal or Indian lands and may be used for the state/ local matching share for apportioned Federal- aid Highway Funds. SRPMIC is a self-governance tribe under the Indian Self- Determination Act ( Public Law 93- 638) and manages Indian Reservation Road funding to maintain its current road system and construct new facilities. The IRR Inventory is a basic requirement for the funding allocation system. SRPMIC maintains a comprehensive database of all transportation facilities eligible for IRR funding. The inventory is approved by both the BIA and the tribe. The BIA uses this roadway characteristics data to generate the construction cost estimates and vehicle miles of travel ( VMT) components of the Relative Need Distribution Factor ( RNDF) for distributing IRR funds. Within SRPMIC, there are 178 miles of Indian Reservation Roads. More than 137 miles are under BIA and Community jurisdiction. The City of Scottsdale maintains pavement, drainage and traffic signals on seven miles of Pima Road. The Maricopa County Department of Transportation ( MCDOT) has jurisdiction of 11 miles, and ADOT has jurisdiction of 23 miles of road. The IRR roadway characteristics database includes classification, route number, bridge number, current traffic volumes, maintenance responsibility, and ownership. Appendix A shows the SRPMIC IRR System Inventory. In addition to a transportation facility inventory, the IRR Program also requires a LRTP. The purpose of the LRTP is to demonstrate a tribe’s transportation needs and develop strategies to meet these needs. The previous SRPMIC LRTP was completed in April 2001. A third IRR Program requirement is the Tribal Transportation Improvement Program ( TTIP). This document is consistent with the LRTP and contains all funded projects programmed for construction in the next three to five years. Typically, BIA selects projects from the TTIP based on funding availability on 1 Title 23 of the United States Code outlines the role of highways in the United States Code. 5 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan a state- by- state basis to develop an IRRTIP for approval by the Secretary of Interior and the Secretary of Transportation. 1.3 Community Outreach Two rounds of Community outreach were conducted for this long range transportation planning effort. The first round focused on issue identification and data collection. The study team conducted interviews with 18 stakeholders, attended Elders’ Breakfasts and conducted two Community Workshops. The team also met with the Young River People’s Council, attended district meetings and attended the Salt River Safety Day. The second round of Community outreach was intended to provide Community members with an overview of the LRTP recommendations and understand any other issues or concerns to be addressed in the study recommendations. The study team attended Elders’ Breakfasts, attended the SRPMIC Earth Day Celebration, conducted two Community Workshops and made two presentations to the SRPMIC Tribal Council. In addition, the study team held meetings at key project milestones with a Technical Advisory Committee ( TAC) that included representatives from ADOT, MCDOT, MAG, City of Scottsdale and SRPMIC. Appendix B includes meeting notes and summary reports from the outreach process. 1.4 Key Issues Key issues identified through the Community outreach process include regional population and employment growth, cut- through traffic, traffic safety, Salt River bridge crossings, public transit and bicycle and walking routes. Growth Population growth within SRPMIC has been relatively slow compared to the increases seen elsewhere in Maricopa County. Census 2000 showed a SRPMIC population of 6,405 living in 11,959 households. Maricopa Association of Governments ( MAG) estimated a July 1, 2008, population of 6,829 living in 2,083 households. This amounts to a 0.8 percent annual growth rate for the eight- year period. Comparatively, total population in Maricopa County grew at an estimated 33.2 percent annual rate for the same eight years increasing from 3.07 million persons in 2000 to 3.95 million persons in 2008. The SRPMIC Enrollment Office set the Community membership as 8,976 as of June 30, 2009. The Community’s statistics indicate that half of the tribe’s population is under age 21. Based upon 2000 Census data, it is critical to note that Community members are much less likely to move or change residences compared to non- members. Over the last decade, more than two- thirds of families reside in the same home. A portion of the SRPMIC membership lives outside of the Community itself. The more significant story within SRPMIC has been employment growth. The Community has developed two casinos – one on McKellips Road, the other on Indian Bend Road. The Pima Freeway corridor is designated for commercial mixed- use and has attracted significant retail and office development. In 2008, SRPMIC identified over 6.8 million square feet of non- residential building space either existing, permitted, or under construction within the Community. In early 2011, SRPMIC will open a new spring training facility located on Pima Road between Indian Bend and Via de Ventura to host the Arizona Diamondbacks and the Colorado Rockies. 6 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan SRPMIC members accustomed to the traditional tranquil way of life are concerned about the impacts on Community roads from the added traffic from both regional population growth and increased commercial activity on the Pima Road corridor. Cut- Through Traffic Cut- through traffic is the top concern for Community members. The issue was raised at the first TAC meeting, the Elders Breakfast, and at other stakeholder and special interest group meetings. Concurrent with this long range transportation planning study effort, the Tribal Council authorized a study by Red Mountain Engineering to identify short term solutions to the cut- through traffic problem. Increased traffic on Community roads has been driven by several factors. Overall regional population growth has meant more vehicles on all roads. The growing congestion on the regional freeway system such as the Red Mountain Freeway ( L202) and Pima Freeway causes drivers to look for shortcuts across the Community. The casinos and Pima Road commercial development are also attracting more trips to the Community. When Pima Freeway is closed by a severe traffic incident, the police department said that Pima Road is the primary traffic detour, which generates additional cut- through traffic across SRPMIC. Traffic Safety The SRPMIC Police Department said in a stakeholder interview that the highest crash locations are located on roads travelling between Pima Road and the Pima Freeway. Chaparral Road and McKellips Road have the highest number of crashes. Livestock- related crashes are prevalent along the State Route 87 ( Beeline Highway). Also along the Beeline Highway, some fatal crashes have occurred with vehicles entering from side streets and being hit by high speed cross traffic. Salt River Bridge Crossings The Salt River separates Lehi from the larger Salt River Pima- Maricopa Indian Community lands. Currently, there are four crossings of the Salt River between Mesa and SRPMIC: Alma School Road, McKellips Road, Country Club Drive, and Gilbert Road. In 2008, floods washed away the riverbed crossing of the northbound lanes of Gilbert Road from Mesa to SRPMIC. The McKellips Road crossing is also a riverbed crossing. In August 2009, MCDOT completed a Design Concept Report to identify preferred bridge locations and designs for crossings at Dobson Road, McKellips Road and Gilbert Road. Public Transit The Salt River Transit System ( SRTS) provides dial- a- ride services for Community residents traveling within the Community, and into Mesa, Tempe, and Scottsdale for shopping, employment, medical and social services. Both Community members and the transit service operators expressed a need for additional service with better connectivity to the regional transit system for access to health care facilities, shopping, work and other activities. Bicycle and Pedestrian Routes There is an overall lack of sidewalks and pedestrian amenities throughout SRPMIC. There are no designated bicycle routes or multiuse paths. During recent outreach, some have said that sidewalks are not a high priority. However, the Elders and the Youth Council both indicated a need to have a safe place for kids so that they do not have to walk in the street. The Elders expressed an interest in multi- use paths for bicycle, pedestrian, or equestrian use. Stakeholders from outside the Community have urged a 7 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan regionally connected multi- use path system. However, the Elders were adamant against providing additional access for the outside public to trespass on the Community. They suggested that any paths should be internal to the Community and not provide connections to encourage use by those living outside of SRPMIC. 8 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan This page is intentionally left blank. 9 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.0 Existing Transportation System Conditions This section describes the SRPMIC existing multimodal transportation system. It provides details on road network, public transit system, and bicycle and pedestrian facility characteristics. In April 2009, SRPMIC completed an inventory of all of the roads and bridges within the Community for the Indian Reservation Roads ( IRR) program. This inventory provides detailed information on road characteristics, including number of travel lanes, BIA functional classification, average daily traffic, route ownership, and surface condition. This section presents the road characteristics data collected by SRPMIC and augmented with data collected as part of this study. Information on the current public transit service and bicycle and pedestrian facilities from interviews conducted with SRPMIC officials is also included. 2.1 Previous Plans and Studies This section identifies previous and current transportation studies reviewed for the preparation of this document. ADOT Arizona Rural Transit Needs Study, 2008 The purpose of this study was to develop regionally based needs and solutions for rural transit service in Arizona. Transit demand in rural Arizona is projected to grow from 7.8 million passenger trips in 2007 to 10.5 million in 2016, an increase of 34 percent. Currently, only 18 percent of estimated demand for rural transit services is being met. Existing rural transit services are projected to meet only 13 percent of total ridership need in 2016 if no additional services are introduced. The study identified steps to address the transit needs of rural Arizona such as adding rural public transit service within cities, towns, and Tribal Reservations to assure service needs of the elderly, persons with disabilities, and the general public are met; connect rural and urban communities, which represents a growing Arizona need; increase funding at all levels of government to support these services, with cooperation from private and non- profit sectors; and, establish clearly defined roles and responsibilities between the state, councils of governments, local governments, Tribal Governments and transit operators. MCDOT Salt River Bridge Crossing Study, 2009 MCDOT has prepared a Design Concept Report ( DCR) dated August 2009 for three bridges to identify the preferred bridge locations and designs for bridges across the Salt River at Dobson Road, McKellips Road, and Gilbert Road. The report also scopes the widening of McKellips Road from the Pima Freeway to the Salt River. These projects are being developed by MCDOT in partnership with SRPMIC and the City of Mesa. The design effort will commence once a partnership agreement is completed on the $ 170+ million project. Pima Road Design Concept Report, 2009 SRPMIC, the City of Scottsdale and ADOT completed a Design Concept Report for Pima Road between McDowell Road and 90th Street. This study established the cross- section and alignment of this key north-south arterial along the Community’s commercial core. The study objectives included improving traffic operations to accommodate growth, improving business access, enhancing corridor character, accommodating multimodal access, and safeguarding adjacent neighborhoods and community resources. The recommended alternative includes four 11- foot travel lanes, two 5- foot bike lanes, and a 14- foot median. The Final DCR was published in October 2009. 10 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Red Mountain Engineering Cut- Through Traffic Study Red Mountain Engineering conducted a cut- through traffic study to identify potential solutions to reduce non- Community travel on SRPMIC roads between Scottsdale and Mesa. Recommendations from this study are incorporated into this Long Range Transportation Planning Study. SRPMIC General Plan, 2006 The SRPMIC General Plan is the Community’s blueprint for land use, development, conservation and preservation. It is the basis for decision making regarding long- term physical development and the protection of the Community’s cultural and natural resources. The plan focuses on establishing a framework of sustainability to ensure that the current and future generations can sustain the social, economic and environmental health of the Community. It includes a land use element and a transportation/ circulation element, which are key inputs into this current long range transportation planning effort. SRPMIC Indian Reservation Roads System Inventory, 2009 The IRR System was last updated in 2009 and included an inventory of all of the roads and bridges within the Community for the IRR program. This inventory provides detailed information on road characteristics, including number of travel lanes, BIA functional classification, average daily traffic, route ownership, and surface condition. The planning effort identified near- term roadway improvement needs that were adopted by the SRPMIC Council as an amendment to the 2001 Transportation Plan. SRPMIC Transportation Planning Study, 2001 The 2001 SRPMIC Transportation Planning Study indentified near- term and long- term transportation needs within SRPMIC. It provided an inventory of the transportation network, an evaluation of transportation needs, and documentation of a 20- year transportation plan that responds to both near-and long- term development scenarios. It also established priorities for implementation of the recommended improvements. This plan updates the 2001 Transportation Planning Study. Salt River Transit Five Year Plan, 2009 The Salt River Transit Five Year plan is a five- year implementation plan that provides the SRTS with a framework for meeting transit service needs in SRPMIC. The plan included Community goals for transit, a transit demand estimate, and strategies for coordinating with other transit services. This plan is also used for evaluating the SRTS for future Section 5311 Rural Public Transportation Program funding. Various Traffic Impact Studies SRPMIC Community Development Department provided copies of traffic impact analysis reports prepared for developments on the Pima Road commercial corridor. These studies were reviewed for socioeconomic and traffic data and road improvement recommendations. 2.2 Road Characteristics and Conditions This section presents the key physical and operating characteristics of major roads within SRPMIC. The key roads are described below: 11 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan North – South Routes Pima Road Pima Road runs north- south along the western boundary of the Community. The road serves as access to the Community’s commercial corridor and the City of Scottsdale. A Final Design Concept Report shows the completed corridor widening to its ultimate four- lane cross- section with two travel lanes in each direction. The City of Scottsdale maintains pavement, drainage and traffic signals on Pima Road. Pima Freeway ( L101) The Pima Freeway is an ADOT facility through SRPMIC east of Pima Road with three general purpose travel lanes and one High Occupancy Vehicle ( HOV) travel lane in each direction. The freeway serves as a vital part of the regional freeway system. This route provides access to both SRPMIC and the City of Scottsdale at nine ( 9) traffic interchanges listed below from south to north: • McKellips Road • McDowell Road • Thomas Road • Indian School Road • Chaparral Road • McDonald Drive • Indian Bend Road • Via de Ventura • Pima Road/ 90th Street 92nd Street 92nd Street runs across the west side of the Community, just east of the Pima Freeway.

Road Lanes and Intersection Control Figure 3 shows total travel lanes for SRPMIC roads. It also shows the location of the 26 signalized intersections within the Community. 2.3 Road Functional Classification SRPMIC roads are classified under two separate functional classification systems: BIA2, and FHWA3 2 Bureau of Indian Affairs. ( October 21, 2004). Coding Guide and Instructions for IRR Inventory. Retrieved September 25, 2009, from BIA Web site, http:// www. doi. gov/ bia/ indianresroads/ irr_ coding_ guide. pdf . Functional classification is the grouping of highways, roads, and streets into classes based on mobility 14 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan and land access. In general, arterials provide greater mobility with less direct access to land, while local roads and collectors provide more access to land with less mobility. Functional classification also serves as a basis for establishing speed limits, parking restrictions, design standards and access controls. A principal arterial, for example, typically provides mobility for longer distance trips with higher speeds and less access to adjoining properties. Conversely, the function of a local street is to provide direct access to neighborhoods at lower speeds. Figure 4 shows the existing BIA road functional classification for Community roads. Appendix C includes a description of BIA functional classification. Figure 4 also shows the Community roads with an FHWA functional classification, which makes them eligible for federal funding. Appendix C also includes a map showing the 2009 FHWA Phoenix- Mesa Urban Area Functionally Classified Roads. The FHWA functional classification definitions are described below: Principal Arterial: This facility serves regional circulation needs. It moves traffic at moderate speeds while providing limited access to adjacent land. Access is controlled through raised medians and through spacing and location of driveways and intersections. Minor Arterial: This facility is generally a four- lane and sometimes a two- lane road. Its purpose is to serve regional/ sub- regional traffic circulation needs by moving traffic at moderate speeds while providing limited access to adjacent land. Major Collector: This facility provides for shorter distance trips, generally less than three miles, and primarily serves to collect and distribute traffic between key traffic generators, local streets and arterial streets. This classification provides direct access to abutting land. Urban Collector: Urban Collectors serve shorter distance trips than the Major Collector ( generally less than one mile). They provide direct access to adjacent land and collect and distribute traffic between key traffic generators, local streets and arterial streets. Local Street: Local Streets provide direct access to adjacent land and distribute traffic to collector facilities. Urban and Rural Areas FHWA designates roads as urban or rural depending on the type of area served. Urban and rural areas have different characteristics, such as density, types of land use, density of street and highway networks and the nature of travel patterns.

There are six levels of service defined by the Transportation Research Boards’ Highway Capacity Manual 2000 ( HCM), published by the Transportation Research Board ( TRB). Each level of service is given a letter designation from A to F, with A representing the optimal or best condition and F the worst Roadway segment level of service is characterized by the HCM as follows: LOS A: Best, free flow operations ( on uninterrupted flow facilities) and very low delay ( on interrupted flow facilities). Freedom to select desired speeds and to maneuver within traffic is extremely high. LOS B: Flow is stable, but presence of other users is noticeable. Freedom to select desired speeds is relatively unaffected, but there is a slight decline in the freedom to maneuver within traffic. LOS C: Flow is stable, but the operation of users is becoming affected by the presence of other users. Maneuvering within traffic requires substantial vigilance on the part of the user. LOS D: High density but stable flow. Speed and freedom to maneuver are severely restricted. The driver is experiencing a generally poor level of comfort and convenience. LOS E: Flow is at or near capacity. All speeds are reduced to a low, but relatively uniform value. Freedom to maneuver within traffic is extremely difficult. Comfort and convenience levels are extremely poor. LOS F: Worse, facility has failed, or a breakdown has occurred. LOS A, B, and C are generally considered to be satisfactory service levels, while the influence of congestion becomes more noticeable at LOS D. LOS E is undesirable and is considered by most agencies to be the limit of acceptable delay, and LOS F conditions are considered to be unacceptable to most drivers. Most jurisdictions strive to attain a LOS of at least D or better on all roads and signalized intersections in urban areas, and LOS C is targeted for rural conditions. LOS Analysis Methodology Two types of level of service analysis were used to evaluate current traffic operation conditions on SRPMIC. The first is a generalized segment level of service analysis. This approach utilizes a lookup table that provides level of service volume thresholds by functional classification and number of through travel lanes. This lookup table, Summary of Generalized Annual Average Daily Volumes for the Phoenix Urban Area, was prepared by MAG for transportation planning studies. The volume thresholds in this table, shown in Appendix D, are based on Phoenix daily traffic characteristics and the HCM. Secondly, level of service analysis for signalized intersections was conducted for intersections in the Pima Road commercial corridor. A traffic microsimulation model was developed for weekday AM and PM peak hours for 32 intersections in the Pima Freeway corridor. Segment LOS Analysis The IRR System Inventory provides average daily traffic ( ADT) for many of the Community roads. The IRR inventory used count data from 2006, 2007 and 2008. These daily traffic counts together with generalized segment level of service thresholds are shown in Figure 5. 18 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan SYNCHRO Model SYNCHRO is transportation operations analysis software prepared by Trafficware. It uses methods described in the HCM to evaluate traffic operations on road systems. It is widely used by traffic engineers for both signalized and non- signalized intersection operations analysis. Peak hour traffic volumes and peak hour factors, intersection lane configurations obtained during site visits, traffic control parameters, and free flow speeds were coded into the SYNCHRO models. A SYNCHRO model was developed for the Pima Road corridor to support the Pima Road Design Concept Report. The HDR study team built on this existing effort and expanded it to include 35 intersections in the Pima Freeway Corridor. This includes all Pima Freeway signalized intersections within the Community. The model also includes intersections on Dobson Road and 92nd Street. The purpose of this Pima Freeway corridor SYNCHRO model is to provide intersection- level traffic operations analysis for both existing and future conditions. This analysis will provide information about the need for installing new traffic signals and the intersection lane configuration needed to accommodate future travel demand. The City of Scottsdale and ADOT provided 2009 signal timing data for the signalized intersections. The study team reviewed a number of studies, including several traffic impact analysis reports and the July 2009 Pima Road traffic analysis report for the DCR, to identify recent traffic counts to support model development. Intersection turning movement counts were conducted in September 2009 for Pima Freeway corridor intersections at locations where no recent traffic data could be identified. The location of the 35 study intersections in the Pima Freeway corridor is shown in Figure 6. Appendix E shows the study intersections’ 2009 lane configuration and traffic control and the 2009 AM and PM peak hour traffic volumes and level of service.

The data provided by ADOT includes incident date and time, crash location, crash severity, crash type, collision manner, environmental conditions, and crash causes. Additional analysis was conducted on the crash information obtained from SRPMIC Police Department ( SRPMIC PD) for the period from January 1, 2005 through July 16, 2009. The data provided by SRPMIC PD contained information about crash location, crash severity, and time and date. The analysis was done to identify potential safety hazards contributing to motor vehicle crashes within the Community and suggest measures to improve safety for motor vehicles and pedestrians. As part of the analysis, a meeting with personnel from SRPMIC PD and a field review was conducted on July 20, 2009. There were 858 crashes reported in the ADOT database and 3,694 crashes in the data provided by SRPMIC PD. It was found that 484 of the crashes reported in SRPMIC PD database were also reported in the ADOT database. The crash analysis presented in the following sections thus analyzed 858 crashes in the ADOT database and 3,210 additional crashes in the SRPMIC PD database. ADOT Data A total of 858 crashes were reported by ADOT within the study area during the five year analysis period. The ADOT data for 2004 and 2005 appears to be incomplete. These years show less than half of the crashes reported in 2003 and 2006. During the study period, 60 percent of the reported crashes occurred at the intersections, while 37 percent occurred at mid- block locations and driveway access points. Table 1 shows the crashes by location and percentage. Crashes occurring within 250- feet radius of an intersection were treated as intersection crashes. Crashes at mid- block locations occurred along roadway sections, at driveway access and alleys.

Figure 12 shows the pedestrian and bicycle crash locations in the study area. As shown in the figure, a majority of pedestrian crashes occurred along McKellips Road and Alma School Road. Crash Observations at High Crash Intersections Based on evaluation of the crash data, interviews with SRPMIC PD, and field observations, the HDR study team reviewed conditions at the high crash intersections and identified near- term corrective measures to mitigate potential safety hazards. This section first discusses the intersection conditions and then addresses potential corrective measures. Pima Freeway- Chaparral Road There were a total of 63 crashes reported at this intersection in the ADOT database over the five year analysis period between June 1, 2003 and May 31, 2008. Angle type crashes ( 75 percent) were the predominant type of crash followed by rear end crash ( 17 percent). Failure to yield the right of way and driver inattention were reported as primary causes of the crashes. Crash analysis also shows that about 28 percent of crashes occurred during dark or unknown lighting conditions. According to the SRPMIC PD, left turn violations and speeding were the primary causes of crashes at this intersection. Left turns from Chaparral Road into the Scottsdale Community College campus, left turns off of the freeway towards the college campus and exiting traffic from Wal- Mart on Chaparral Road were some of the movements that were involved in crashes. It is also noted that the left turn traffic from Chaparral Road into the college campus is heavy.

The SRPMIC PD database shows that 74 crashes occurred near the Pima Freeway- Chaparral Road traffic interchange between January 1, 2005 and July 16, 2009. 36 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Corrective Measures Most of the crashes at these high crash intersections occurred due to the driver inattention. Some of the potential corrective measures that can be made to reduce these types of crashes occurring at intersections include: a) Install a raised median on Chaparral Road between the Pima Freeway traffic interchange and Pima Road. b) Install Recessed Pavement Markers ( RPM) along lane markings, rumble strips along edge lines of the roadway to obtain driver attention. c) Flexible reflective delineators and lighted flexible boulder signs should be considered along painted island curbs at tight left turn movements to obtain driver attention. d) Optically programmed signal heads should be considered for eastbound and westbound traffic at Thomas Road- Pima Road and Thomas Road- Pima Freeway traffic interchange. e) A modern roundabout could be an alternative for an intersection with history of crashes due to left turns and higher speeds. It would also serve as a traffic calming measure. 37 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.8 Public Transit Salt River Transit Public transportation serves a variety of functions for the SRPMIC. It gives mobility to persons without access to an automobile and to those who do not drive and it provides important links between rural communities and metropolitan areas. According to the 2000 Census, 13 percent of SRPMIC households had no vehicle available, one- third of the Community is under 18 years of age, and an additional 12 percent are over 65 years of age. The Salt River Pima- Maricopa Indian Community Transit System ( SRTS) provides dial- a- ride services for tribal residents traveling to Mesa, Tempe, and Scottsdale for shopping, employment, medical and social services. Salt River Transit has been providing transit services to Community members since 1983. The mission statement of the SRTS is: “ The transit system provides safe and efficient transportation service to residents, tribal employees and the general public to the SRPMIC. Our primary purpose and continued goal is to provide service and assistance to residents in reaching destinations such as medical facilities, employment centers, education facilities, shopping centers and other areas.” Review of summary ridership information provided by the Community shows that ridership numbers are stable with little monthly fluctuation. Community staff reported there is a noticeable drop in ridership when quarterly benefit checks are received, but levels quickly adjust back to baseline. Existing Service Route Descriptions The current service routes have been developed over time addressing the needs of the Community members, resulting in a rider base that is stable and predictable. Figure 13 shows their areas of coverage and the surrounding Valley Metro Transit service. Table 9 describes the service routes.

As can be seen in Figure 13, the service area boundaries of the current routes cover most of the areas of residential and commercial development within the Community ( with the notable exception of the commercial development north of Indian Bend Road). The service areas extend beyond the Community boundaries to provide transportation to important destinations for Community members including Scottsdale Healthcare and regional shopping centers. Important destinations identified by SRTS staff include the following ( in no particular order): • Fiesta Mall, Mesa • Sycamore/ Main Street Light Rail Transit Stop, Mesa • Riverview Mall, Mesa • Fry's Food Store 77th Street and E McDowell Road, Scottsdale • Pavilions, Indian Bend and Pima Freeway, Scottsdale • Scottsdale Healthcare, Scottsdale • SRPMIC Tribal Complex • Casino Arizona, McKellips • Scottsdale Community College, Chaparral 40 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Transfer points for SRTS to Valley Metro routes include: • McDowell and Granite Reef Road ( Valley Metro Route 17, McDowell Road) • Hayden and Thomas ( Valley Metro Route 29, Thomas Road) • Scottsdale Community College ( Valley Metro Route 50, Camelback Road; and 76, Miller Road • Country Club Drive and McKellips ( Valley Metro Route 112, Country Club Drive/ Arizona Avenue) • The Pavilions The SRPMIC Department of Transportation director has been in contact with Valley Metro staff to discuss the opportunity for the extension of Valley Metro service to the Tribal Headquarters at Longmore and Osborne. SRTS trips beyond the Community could transfer to Valley Metro from these locations. Current economic conditions have delayed action on this, but interest exists to continue to explore this option. Transit Planning In 2009 ADOT prepared the Salt River Transit Five Year Plan ( Transit Plan). This Plan, prepared in support of the 5311 funding received from ADOT, identifies the Community’s goals for transit, transit demand, and a five- year implementation plan. The plans provide a five- year ‘ road map’ to address the transportation needs and coordination of public transportation and specialized transportation services for the elderly and disabled in the regions. In addition, they address the most efficient and effective management and funding programs for public transportation. These plans include an assessment of local transit needs within a five- year “ horizon,” achievable coordination and consolidation opportunities and a significant public involvement process. As part of the Transit Plan a rider survey was conducted in November 2008. The survey found that the primary trip purpose of riders is employment ( 35 percent), followed by education ( 20 percent) and medical purposes ( 17 percent). The survey found that all respondents would like to see weekend service and many asked that weekday service be extended to 7 p. m. Eighty- five percent of the riders ride Monday- Friday. This finding was confirmed by comments during outreach with a Tribal Council district meeting that suggested an extension of service to 9 or 10 p. m. The Transit Plan also assessed the transit dependent population within the Community, based on the work done in ADOT’s Arizona Rural Transit Needs Study ( May 2008). This study determined transit dependent populations and demand by County for the entire state based upon the Arkansas Public Transportation Needs Assessment ( APTNA) method4 Transit Funding . The Transit Plan estimated the transit dependent population within the Community, using SRPMIC’s population relative to the total rural Maricopa County population. For this study, we have evaluated the transit dependent population by direct application of the 2000 Census data. Funding for rural transit services comes from several sources: the Federal Transit Administration ( FTA) Section 5311 Rural Transportation funds and the SRPMIC. For the 2009 operating year, approximately 60 percent funding came from Section 5311 grant funding with the remaining 40 percent coming directly from the SRPMIC. 4 The Arkansas Public Transportation Needs Assessment ( APTNA) method represents the demand for transit service by applying trip rates to three population groups: elderly persons ages 60 and over, persons with disabilities under age 60, and persons living in poverty under age 60. 41 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan The current fare structure for each one- way trip is shown in Table 10. Although the fares are relatively low in comparison to other rural transit providers, there is a strong commitment to maintaining an inexpensive transportation option for Community members. Table 10 SRPMIC Fare Structure One- Way Trip Fares General Seniors/ Disabled Within the Community $. 75 $. 25 Outside the community $. 85 $. 50 Source: Salt River Pima- Maricopa Indian Community Transportation Department, Transit Division ( 2009). Rural Public Transportation Program ( Section 5311) The Section 5311 Rural Public Transportation Program provides capital, administrative and operating assistance for public transportation programs in rural and small urban areas. FTA Section 5311 funding supports capital expenditures, operating expenses, and administrative expenses. A local match is required with the amount varying by program. They may be used for general public transit services in rural areas ( those areas with less than 50,000 in population). The FTA apportionment funding is allocated to states on a population- based formula. The ADOT Multimodal Planning Division awards the funds to participating systems through an annual competitive application process and acts as administrator for the 5311 program. Besides the SRPMIC, the Hopi Tribe and Navajo Nation are the only tribes in Arizona currently receiving Section 5311 grant funding. Recommendations from ADOT’s 5- year plan focus on five key areas: 1) management structure and administration, 2) effectiveness of service, 3) marketing, 4) coordination ( both locally and within the region), and capital planning. The reader may refer to that plan, on file with the Transit Department, for specifics and recommendations. Operations Information The SRTS fleet currently includes nine vehicles: ( 3) 14 Foot Passenger Vans, ( 1) 13 Foot Passenger Van, and, ( 5) 11 Foot Passenger Vans. These vehicles were all purchased with Community funds. Table 11 shows SRTS service data for Fiscal Year 2008. Table 12 shows the SRPMIC transit costs for Fiscal Year 2008. 42 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 11 Service Data for Fiscal Year 2008 Service Measure Amount Service Days per Week 5 Annual Revenue Miles 141,136 Annual Passenger Trips 22,419 Fares Collected $ 16,126 Vehicle Revenue Hours 9,464 Cost per Passenger Trip $ 22.75 Cost per Revenue Mile $ 3.61 Source: ADOT, Fiscal Year 2008 Section 5311 Annual Report.

Transit Dependent Populations For the vast majority of trips produced and/ or attracted in the SRPMIC area, there are few viable alternatives to the automobile. Segregation of land uses and nearly universal automobile availability has resulted in dispersed land uses that are difficult to reach without an automobile, as well as little or no alternate modes of travel. Not only is there little public transportation service available, the distances between origin and destination and lack of facilities for pedestrians and bicyclists makes walking or riding a bicycle impractical and/ or unsafe. In most cases, about the only viable alternative to driving somewhere is riding there with someone else. Transit Demand Using the APTNA, populations of elderly persons age 60 and over, persons with disability under the age of 60, and persons living in poverty under age 60 are considered transit dependent populations. Within the SRPMIC Community an assessment of these populations indicates that as much as 60 percent of the population would be considered transit dependent5 To determine the potential demand for transit services, the APTNA assessed trip rates based on Census information, which was reported as an annual trip rate for each group. The findings are reported in . Table 13. 5 This is based on Census 2000 information for the SRPMIC which reveals 16 percent of the population is over age 60; 28 percent of the population under 65 is in poverty; and an additional 19 percent of the age 5 to 65 population has a disability. Adjusting for the population of the last two groups over 60, the resulting transit dependent population is equivalent to 60 percent of the Community’s population. 43 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 13 Annual Transit Trip Rates for Select Demographic Groups Demographic Group Trip Rates: Annual One- Way Passenger Trips Elderly persons Age 60 and Over 6.79 Persons with Disability Under Age 60 4.49 Persons living in Poverty Under Age 60 20.5 Source: Salt River Transit Five- Year Plan, January 2009. Using these trip rates, it was determined that the 2009 transit demand estimate for the SRPMIC Community is 48,377. When compared to the 22,419 annual passenger trips recorded in 2008, this estimate represents an additional 26,000 trips ( 116 percent additional annual trips) of current unmet transit demand. 44 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 2.9 Non- Motorized Transportation Today, there are few paved or un- paved trails within the SRPMIC. The rural character of the Community, characterized by its narrow roads with no curb or gutter, requires pedestrians to walk along edge of pavement and in some cases where obstructions or canal laterals exist, pedestrians have to walk on the pavement. Sidewalks are present only in some of the newer developments, subdivisions within the People’s Village, around some of the commercial development in the Pima Freeway corridor and at the Government Complex. Even with the sidewalks in place adjacent to some of the denser subdivisions, there is little connectivity with schools or activity centers. The 2006 SRPMIC General Plan includes a number of objectives and implementation measures addressing the need for improved pedestrian connectivity. Figure 14 shows the Salt River Elementary School, one of the few locations with sidewalks. Figure 14 Salt River Elementary School Sidewalks The General Plan identifies the creation of a trails master plan to connect activity areas for pedestrians, bicyclists, and equestrians within the Community as one of the Actions/ Implementation Measures ( IM 24, SRPMIC General Plan, 2006). 45 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 3.0 Land Use and Socioeconomic Conditions This section provides an overview of the existing land use together with estimates of SRPMIC population and employment. The demographic information used in this analysis is from the 2000 Census. While this information is nearly ten years old, the 2000 Census remains the most comprehensive source of demographic data available. When appropriate and available, other more recent socioeconomic information is cited. Demographic information is important in developing a profile of the Community’s residents and households. A comparative analysis with data from the county and state is included to illustrate how SRPMIC relates to the greater metropolitan area and state. 3.1 Title VI and Environmental Justice The Environmental Protection Agency and FHWA define environmental justice as the “ fair treatment for people of all races, cultures, and incomes, regarding the development of environmental laws, regulations, and policies.” Environmental justice principles and procedures are followed to improve all levels of transportation decision making. Title VI of the Civil Rights Act of 1964 prohibits discrimination on the basis of race, color, or national origin. The 1994 Executive Order 12898 on environmental justice addresses minority and low- income populations. The rights of women, the elderly, and the disabled are protected under related statutes. These Presidential Executive Orders and other related statutes fall under the umbrella of Title VI. There are three fundamental environmental justice principles applicable to the transportation project development process: • to avoid, minimize, or mitigate disproportionately high and adverse human health and environmental effects, including social and economic effects, on minority populations and low- income populations • to ensure the full and fair participation by all potentially affected communities in the transportation decision- making process • to prevent the denial of, reduction in, or significant delay in the receipt of benefits by minority and low- income populations Effective transportation decision making depends on understanding and properly addressing the unique needs of different socioeconomic groups. Properly implemented, environmental justice principles and procedures improve all levels of transportation decision making. The five minority groups addressed by Title VI and Executive Order 12898, Environmental Justice, are: • Black ( a person having origins in any of the black racial groups of Africa) • Hispanic ( a person of Mexican, Puerto Rican, Cuban, Central or South American, or other Spanish culture or origin, regardless of race) • Asian American ( a person having origins in any of the original peoples of the Far East, Southeast Asia, the Indian subcontinent, or the Pacific Islands) • American Indian and Alaskan Native ( a person having origins in any of the original people of North America and who maintains cultural identification through tribal affiliation or community recognition) • Some other race, or persons of more than one race 46 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan A member of the low- income population is defined as “ a person whose household income is at or below the Department of Health and Human Services poverty guidelines.” The Department of Health and Human Services poverty guidelines state that the poverty level for a family of four in 2009 is $ 22,050 ( note, however, that this income level cannot be compared directly with current income levels because the value of money changes year to year). Other protected populations include concentrations of elderly, the disabled and female heads of households. These populations for the SRPMIC Community, Maricopa County and Arizona are shown in Table 14. Table 14 Title VI and Environmental Justice Population Percentages, SRPMIC, Maricopa County and Arizona Category Arizona Maricopa County SRPMIC Minority 36.2% 33.8% 82.5% Hispanic or Latino 25.3% 24.8% 16.9% Black or African American 2.8% 3.5% 0.4% American Indian or Alaskan Native 4.5% 1.5% 45.6% Asian 1.7% 2.1% 0.1% Native Hawaiian or Other Pacific Islander 0.1% 0.1% < 0.1% Some Other Race 0.1% 0.1% 10.6% More than One Race 1.6% 1.7% 8.8% Persons Living Below the Poverty Level 13.9% 11.7% 30.5% Disabled 19.3% 18.0% 27.7% Age 65 and Older 13.0% 11.7% 12.5% Female Heads of Household 6.8% 6.6% 14.1% Source: Census 2000 Redistricting Data ( PL94- 171) Summary File. The protected populations considered in this analysis are described below: • Minority populations include people who identify themselves as Hispanic or Latino, Black or African American, American Indian and Alaskan Native, Asian, Native Hawaiian and Other Pacific Islander, persons of some other race, or persons of more than one race. • Low- income populations include people living in households with an income at or below the U. S. Department of Health and Human Services poverty guidelines. Low- income populations may have greater difficulty locating replacement housing in the area. They may rely on public services and facilities, such as public transit and public recreational amenities, to a greater extent than the general population. • Elderly populations consist of people who are age 65 and older. While elderly citizens often drive, the National Highway Traffic Safety Administration ( NHTSA) reports that both high-speed and high- traffic routes may present a problem for some ( NHTSA, 2007). In addition, the elderly may have a need for transit service or may opt to use transit if it is offered. • Disabled populations are civilian, non- institutionalized persons aged 5 and over with disabilities ( such as sensory, physical, mental, self- care, going outside of home, and 47 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan employment disabilities). • Female head- of- household populations consist of households headed by a female with no husband present and with her own children under the age of 18. These households tend to have lower incomes than households headed by married couples or a single man and oftentimes have a greater need for affordable housing. Poverty is a major concern of the Salt River Pima- Maricopa Indian Community with the median per capita income of $ 9,592 ( more than 56 percent below the national per capita income of $ 22,000). The percentage of the population in poverty is 30.5 percent, more than twice that of the overall state poverty level of 14 percent. 3.2 Existing and Planned Land Use The Community is rural in character with over 90 percent of the area classified as either open space or vacant. Commercial and industrial development is limited to the periphery of the Community along major transportation corridors. The Community encompasses approximately 85 square miles ( 54,632 acres), with 19,000 held as a natural preserve and approximately 17,000 acres under cultivation in a variety of crops including cotton, melons, potatoes, onions, broccoli and carrots.

The SRPMIC General Plan Land Use Map shown in Figure 15 identifies 11 planned land use designations and two special area designations for the Pima Freeway corridor and the People’s Village. The Pima Freeway corridor is the Community’s economic growth area. It extends north- south along the Pima Freeway from McKellips Road to the Community’s northern boundary. The People’s Village, located in the heart of the Community, is intended to be a Community- oriented focal point of activity. 48 Salt River Pima- Maricopa Indian Community Transportation Planning Study Figure 15 2006 General Plan Land Use Map 49 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan 3.3 Traffic Analysis Zones Traffic analysis zones ( TAZ) are geographic areas generally bounded by roads, railroads, major watercourses or other easily identifiable physical features. SRPMIC socioeconomic data is tabulated by TAZ geography. Using the City of Scottsdale Travel Demand Model ( STDM), traffic is generated by each land use within the TAZ, distributed, and then assigned to the roadway network. Subsequently, using projected land use data, future traffic forecasts can be derived. 3.4 Population It is estimated that approximately 7,188 of the Communities 8,976 members live on the reservation6 The median age of the SRPMIC population is 28.3, compared with 34.2 for Arizona. Much of the population is young with 39.7 percent of the population under 20 years of age. For Arizona as a whole, 29.7 percent of the population is under 20 years of age. This is important information because age helps dictate transportation mode choice and walking rates are drastically higher for younger age groups than older ones. The 5– 15 year old age group has almost twice the percentage of walking trips as the 40– 64 year old age group . The U. S. Census reported a 2000 population of 6,405. Many members live on scattered home- sites largely located south of the Arizona Canal, which essentially bisects the Community east- west; in the Lehi area, located south of the Salt River; and in the People’s Village, a two and one- quarter square mile area that is developing as a focal point of activity for Community members. 7 The average household size in the Community is 3.24 persons per household, 20 percent higher than that of Maricopa County ( average household size is 2.67; slightly higher than Arizona as a whole, which is 2.64). . Figure 16 shows the estimated 2006 SRPMIC population density by TAZ. 6 The reported population of 8,976 members is from the Salt River Pima- Maricopa Indian Community’s Enrollment Office. The 2009 population estimate is extrapolated from the 2000 Census population and the Maricopa Association of Governments’ 2007 socioeconomic projections. 7 Pucher, J. and Renne, J. ( 2003).

This figure of nearly 23 percent vacant is more often seen in communities with a high percentage of second or vacation homes. SRPMIC staff and census data indicate that this higher vacancy rate is attributable to the Shadow Mountain Village and Roadrunner Lake Resort mobile home parks that lease land from the Community. Primarily non- SRPMIC members live in the mobile home parks. On the other hand, the home ownership rate for the SRPMIC is over 80 percent, significantly higher than the 68 percent for Maricopa County or the state as a whole. Table 17 shows a comparison of key housing statistics for SRPMIC, Maricopa County, and Arizona.

During the same ten- year period, Maricopa County grew over 45 percent. Generally consistent with its growth in the previous decade, Maricopa County grew nearly 20 percent between 2000 and 2005. However, the MAG Socioeconomic Projections of Population, Housing, and Employment by Municipal Planning Area and Regional Analysis Zone, May 2007, show that SRPMIC grew by only seven percent over the same five- year period. While Maricopa County continued to grow at more than 3 percent annually, the rate of growth in the SRPMIC slowed in relation to the county as a whole between 2000 and 2005. 54 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 18 Historic Population Growth Description 1990a 2000b 2005c POPd HHe POPd HHe POPd HHe Maricopa County 2,122,101 807,560 3,072,366 1,132,886 3,616,690 1,352,967 SRPMIC 4,852 1,583 6,355 1,959 6,742 2,056 Source: HDR Engineering, Inc., September 2010.

General Plan Land Use Considerations Although more than 83 percent of SRPMIC is open space, there is a shortage of land for new residential development. This is largely due to the allotment system of land ownership across the Community. Cooperation of multiple landowners is required to assemble a parcel large enough for a subdivision. This makes large- scale residential developments challenging. Additionally, it is difficult for Community members who are not landholders to buy and develop land in the Community. One of the goals of the SRPMIC General Plan is to promote residential development to accommodate the housing needs of Community members. This development effort is focused on the People’s Village and includes such subdivisions as “ Victory Acres” and “ Canalside”, located south of the Arizona Canal between Country Club Drive and Mesa Drive. These subdivisions were formed from existing tribally owned lands set aside for Community purposes. With the completion of the latest Canalside subdivision, there are additional 91 parcels available for development. While there is a shortfall of land for new residential development, the SRPMIC General Plan designates eight percent of its land area, or over 4,500 acres, for mixed- use commercial development. This is located primarily along the Pima Freeway Corridor. Currently the corridor contains two Casino Arizona locations, golf courses, and retail and commercial office development. A new convention center and hotel opened in 2010. A spring training facility is under construction and due to open in early 2011. In addition to the new hospitality and sports developments, commercial and retail development along Pima Road is also growing. Wal- Mart is currently expanding at its location on Chaparral Road. New office buildings in Pima Center and Riverwalk are permitted or under construction. Population Projections Recent MAG estimates show SRPMIC population growth slowing. Between 2005 and 2030 MAG estimates that the Community will grow by 0.34 percent annually. This is well below the 2.8 percent annual growth recorded between 1990 and 2000. In large part, population growth is limited by the availability of land for residential development. As noted earlier, the SRPMIC Housing Department is completing Canalside III and IV with 91 new home sites for Community members. It is located along the Arizona Canal in the People’s Village between Mesa Drive and Country Club Drive. Build out of the Canalside home sites is assumed by 2030. The Community is also planning a multifamily village development on the northwest corner of Chaparral Drive and Dobson Road; an area shown as a high density residential development in the SRPMIC 55 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan General Plan. Build out of the multifamily village, which is anticipated to occur by 2030, will provide between 220 and 240 new residences. The Housing Department is also considering new subdivisions on Country Club Drive and Center Street between Indian School Road and Camelback Road. The size and timing of these subdivisions is unknown. Currently, SRPMIC leases land to two mobile home parks: Shadow Mountain Village is located north of McKellips Road west of the Pima Freeway; and, the Roadrunner Lake Resort is located on 92nd Street north of McKellips Road. Residents of Shadow Mountain Village and Roadrunner Lake Resort are predominately older non- SRPMIC members. The demographics of these mobile home parks show a larger number of seasonal homes and smaller household sizes that change the picture of the SRPMIC demographics. Census 2000 data for overall SRPMIC shows that 77 percent of housing units were occupied. Average household size was 3.24 persons per household. However, SRPMIC Housing Department officials describe long waiting lists for Community housing with high occupancy rates. Without Shadow Mountain Village and the Roadrunner Lake Resort, Census 2000 data reflects the tight demand for Community housing with occupancy rates over 95 percent. Average household size is 4.21 persons per household. The leases for both mobile home parks are set to expire by 2030. The Shadow Mountain Village lease will expire in 2027. The Roadrunner Lake Resort lease will expire in 2019. SRPMIC plans to include the areas in its commercial and retail redevelopment plans. The eventual closure of the mobile home parks will mean a loss of population for SRPMIC because most of the mobile home park residents are not Community members. Only Community members and their families are allowed to live on SRPMIC. The 2030 population projections for this study are based on the following: • Full buildout and occupancy of the 331 planned new Canalside and the multifamily village residences. • Population lost from the closure of the Roadrunner Lake Resort in 2019 will be replaced by Community members living on new home sites in allotted lands. • Since Shadow Mountain Village will remain in place through most of this study’s planning horizon, its population is included in the 2030 projections. • Average household size estimated at traffic analysis zone ( TAZ) level based on Census 2000. Table 19 shows the population projections. Figure 18 shows the 2030 population distribution by TAZ. The thematic map colors represent population per square mile. The labels show the population projection by TAZ. Population projections for the interim planning horizons of 2015 and 2020 are interpolated values. 56 Salt River Pima- Maricopa Indian Community 2010 Long Range Transportation Plan Table 19 SRPMIC Population Projections Description Year 2009 2015 2020 2030b Households 2,219 2,303 2,373 2,510 Populationa 7,188 7,690 8,100 8,900 Source: HDR Engineering, September 2010.
