ii PREFACE

During the month of June 1977, numerous aeetings were held between key staff •••hers of the State Plan Section and the Demography and Land Use section. The purpose of these

meetings was to develop a 11ut uall y acceptable wort program in respect to the establishment of an existing and future land use data base. This data base would be designed specifically to meet statewide transportation planning needs on a continuing basis.

As a startinq point, it vas mutually agreed that an

initial report would be prepared containing a variety· of data ger11ane to land features such as floodplains and subsidence. Additionally, relevant data would be presented in respect to major activity centers such as 11ajo1. education centers and hospitals. It must be emphasized that the assignment involved more than mere fact finding. In actuality, the collection, analysis, and presentation of data occurred only after agreement was reached on basic criteria--for all items to be studied.

This report was prepared as a result of the efforts of a number of staff members. Resource material was used from

many agencies within both the public and private sectors. A

Bibliography is included in the Appendix for information

purposes. In particular, a,11 authors are especially grateful to Dr. Richard w. Reeves, Head of the Department of

iii Geography, College of Business and Public Administration,

The University of Arizona. Dr. Reeves authorized the loan and use of approximately 25 maps from the Arizona Atlas, which is soon to be publishe.d by the Division of Economic and Business Research at The University of Arizona. Obviously, countless hours of research, analysis, and drafting-related work were saved.

Your comments and suggestions on any aspect of this study are welcomed. In this way, staff will be better informed in respect to your needs.

CHAPTER I

INTRODUCTION

This chapter discusses the purpose and scope of the land features and major activity centers study. It contains definitions, research assumptions, and organization information which should prove helpful to the prospective user. fl!~~22-Ang_~Q~~-21_i~2rt

The rec en tl y-released report entitled "Arizona

Transportation Directions--Tovard a State Transportation

Plan" notes that the first integrated Arizona Transportation systems Plan (based upon statewide transportation goals and objectives) will be completed by January 1, 1979. The formulation of realistic statewide goals and objectives will require analysis of a comprehensive transportation and land use data base. Therefore, an i ■ portant ia ■ediate objective of the Arizona Department of Transportation's (ADOT)

Demography and Land Use Section has been to establish an existing and future land use data base designed to aeet statewide transportation planning needs. The information generated by this study may be used as part of the state planning process to reco■■ end the i ■ proveaent of existing facilities, to delineate new transportation corridors, or to determine potentially developable lands.

I-1 After a series of meetings in June, 1977, vith the ADOT

State Plan Section, the Demography and L~nd Use Section agreed to prepare a study focusing on principal land features and major activity centers within the State of

Arizona. In contrast to the conventional, categorical atlas, this study presents resource material on land use activities, an approach which will provide a more useful basis for transportation planning decisions. In general, the primary purpose of this report is to furnish accurate data pertaining to land features and major activity centers that will be of immediate value for statewide transportation planning. The scope of the study is discussed in the next few paragraphs. Land features. are considered in this report because the physical qualities of any geographic are• will influence both the form and structure of development. These basic influences may constrain the location and construction of transportation facilities; however, they may also pr.esent unique opportunities for innovative/scenic transportation facilities. Additionally, transportation systems maJ have significant impacts upon physical land features as well as the "built environment". Good transportation planning practices, as well as federal regulations, require attention to both of these areas. Knowledge of the location and extent of these land features is essential to perform state transportation planning.

I-2 This study contains nine items which have been classified broadlf. as land features (either physical qualities such as topographic slope and flood plains or

"built environment" such as historic structures and agriculture). Chapter II describes the detailed characteristics of these features.

Major activity centers are defined as significant concentrations of people, employees, goods, or services that are a focus for transportation service. Further, they a.re generally characterized by high densities of land use and are significant traffic generators. They may be readily classified by trip-type, including work, school, shopping, socia 1, and recreation trip purposes.

This study contains seventeen items that may be classi£ied generally as aajor activity centers, according to the above definition. Examples of these activity centers are: industrial parks, education centers, .regional shopping centers, special events, and lumbering operations. Cb.apter

III provides more detailed descriptions of these centers.

~!!gJ._!§!H!!!,EtiQ.!!.§_.9!!,g_£2!!2idi~sii2112 For information purposes, the following paragraphs summari~e significant study assumptions and considerations: Assumptions:

• Major activity center data for smaller municipalities is more important from a Statewide

Transportation standpoint than for Phoenix and

I-3 Tucson where the urban complex itself is the

overwhelming at traction. For this reason,

emphasis was placed on obtaining activity center

data outside the highly-urbanized areas.

• With respect to the inclusion of a particular activity center, the following four criteria were used in most cases:

a. The magnitude of the transportation system

required to sustain the activity e.g., 3,000,000 visitors per year at Grand Canyon

National Park.

b. The nature of the activity in terms of importance to life-support e.g., the only hospital or educational center in an area. c. The areal importance of the activity.

Activities that attract or cause long trips, whether person or goods, are generally more important statewide than local attractors. d. The direct impact on the operation of a statewide trans~ortation facility e.g., the Ensphere in Flagstaff. considerations: • To develop a prioritized listing of major activity centers and land features.

I-4 • To collect, where possible, specific data on planned major developments e.g., a new power plant in Springerville. • To present, where possible, quantitative data concerning the level of activity or land use e.g., annual visitor days at a recreational area or the number of acres in a regional park. • To develop an overlay mapping technique to display

characteristics of important data items. For example, land features such as flood plains, land subsidence, topographic slope, public lands, urban areas, and historic and archaeological sites would

be over layed to reveal residua 1 "potential! y developable lands". The first three of these considerations were fulfilled

.by the study process and are presented in Chapters II and

III. The fourth objective was not achieved for the reasons cited, as fallows: 1. It was impossible for staff to collect and analyze data on all critical factors, and to conduct all

required coordination, during the ti ■e-span allocated for this initial effort.

2. Tremendous land use data gaps exist on a Statewide basis including, but not liaited to, the availability of either an existing or future land

use aap; a vacant lands •aP-; the quantity,

I-5 quality, and location of ground-water reserves;

plus supporting narrative and, statistical

analyses. Yet, it should be emphasized that the • 11 overlay process" approach is sound, and in the

future it could be used in a ■ ore liai ted vay

e.g., for transportation corridor feasibility

studies.

Prior to the collection, analysis, and presentation of

·data it was necessary for staff to establish criteria relevdnt to a particular activity center or land feature item. For example, in the case of Major Education Centers, the number of stud~nts entolled at a facility, contingent on its location in a major urban or rural area, would be the criteria for inclusion. Further, agreement was reached on specific data characteristics to be researched with respect to an item. Again, in the case of Major Education C•nters, data including the name, location, area, enrollment, faculty and staff, and number of parking spaces vere collected. The definition of specific criteria prevented the collection of insignificant data during the study process. With respect to the research itself, staff used resource material from numerous sources in the public and private sectors. Data was acquired from Federal, State, and

Local governmental agencies; and from commercial firms and

Chambers of commerce. Specific references are identified on each table and 11ap contained in the study. F urt:.he r, the

Bibliography provides the reader with an overview of sourc;,c,,

.information. !~EQ~t-2IS1aai1a&2A The organization of the remainder of this report is as

follows. The next chapter contains data on nine land

features. Generally, each item is formatted with

descriptive text, a statistical table(s), and a thematic

map(s}--with a singular identification number. Chapter III

contains data on seventeen items that fall within the major

activity centers category. All items in Chapter III are

formattad identically to those in the land features chaf:'ter.

Chapter IV contains report Conclusions and Recommendations,

and it is followed by an Appendix containing highly detailed

technical information.

For user convenience, an Arizona geographical locator

transparency is provided in the pocket affixed to the back

inside cover. The locator will be helpful in relating land

features/major activity centers to the State Highway System

and communities served by that system.

In summary, the report presents an inventory of land

use features and activities which should be useful in the preparation of the Arizona Transportation Systems Plan document. Also, this document may be useful to other ADOT

sections which utilize land use data in making

transportation planning decisions.

Arizona has three basic climates: desert. plateau, and highlands. This causes Arizona to have an extreae range of temperatures. Annual averages vary from the aid-forties in the highlands to the mid-seventies in the deserts. Arid conditions are also variable. tacit of precipitation is characteristic of the deserts and plateaus. In these areas, most rains tend to evaporate or run off thus minimizing subsurface storage. Suaaer rainfall is usually associated with cloudbursts and can cause sudden damage to life and property. Such rains tend to inundate vashes and gullies beyond capacities causing flooding conditions vi th considerable damage to roads and iaproperly situated hoaes.

In contrast, the highlands nor ■ ally receive sufficient precipitation to support a moderately dense vegetation as vell as provide sufficient runoff to the surroonding arid regions.

The State· is divided into ten cli ■ate forecast zones by the National leather service as shown on flap Bo. 501. These are: Northeast Plateaµ

Little Colorado Valley

Grana canyon ttogollon Rim- White Mountains

X:t-2 Northwest Arizona

Central Basins southeast Arizona

Southwest Deserts Colorado River Valley

The purpose of this division is to identify regions in the State that have rel a ti vel y uni fora weather conditions during a standard forecast p~riod.

Table No. 501 reflects information published by the

National Weather Service pertinent t~ temperature and precipitation over a 30-year period. Recognition of the various climatic conditions must be considered as input into the development of a transportation plan, particularly in those areas of frequent flood or other drainage problems. Special consideration 11ust also be given to heavy snow conditions in the upper highlands and extreme dust conditions that plague the desert areas.

rtetallic and non- metallic mineral deposits and occurrences are eYident throughout the State*. Improvement in the methods of extraction and increases in economic value have encouraged expansion and new development of mining activities. '!et.u!!~ As evidenced by Tables No. 502-A and 502-B, copper is the 11ost produced mineral in both quantity and value. While deposits and occurrences are spread across the State, ma_jor concentrations are found in the southern and western portions of the State. According to the Sfate Geologica 1 survey, formerly the Arizona Bureau of "ines, there are 27 types of metallic occurrences in the State. The most important of these are copper, molybdenum, sil¥er, and gold. Mon-ft~Ulli£ There are 30 types of non-metallic mineral occurrences in the State ranging from Alunite to Zeolite. Industrial rocks are included in this category. Development in the extraction of aany of these non-metallic ■ inerals is not very pronounced. The reason for this is that these types of minerals are almost always low in unit value and generally consist of co ■ mon rock aaterial. In addition, their Yalue is generally dependent on the local ■ arket. When population

II-6 increases and i ■ proved access is provided, interest in these

non-metallic minerals· is sti ■ ulated. While aost of these products have been used locally, a few ptoducts with higher

unit value have been marketed outside of the State. These include asbestos, feldspar, and quartz. Important industrial rocks are clay, gypsu11, pumice, sand and gravel, and stone. Tables 502-A and 502-B reveal that sand and gravel are

the most produced non-metallic minerals in both quantity and value.

Table 502-C indicates that all 1~ counties produce some type of mineral; also, the minerals are ranked in order of

value by county. 11ill.fil:5L!~.!§ Coal, crude oil, helium, and natural gas are mineral fuels being produced in the state. Production is primarily taking place in Apache County, northern Navajo County, and eastern Coconino County. Significant coal reserve.s exist in Apache, Coconino, Gila. Navajo, and Pinal Counties. These coal reserves are located at Black ~esa over an area covering about 3,500 square 11iles, at Pinedale covering about 175 square miles, and at Deer Creek covering about 50 square ailes. In fact, Arizona has one of the largest coal reserves in the world. The location of these reserves, together vi th other selected resources, are shown on Nap No.

502-A.

rr-7 Due to the significant deposits and occurrences of the various minerals throughout the State, the future is bright in the area of recoverable natural resources. New developments and expansion of existing mininq activities can be expected in the future, particularly as prospecting and mining methods continue to improve. !alfil: A very important natural resource is water. It is also not overly abundant due to the general aridity of the state.

'!'his is evidenced by the fact that almost half of the State receives less than 10 inches of precipitation per year, while a large part of the rest of the State receives less than 20 inches of precipitation.

The state is divided into three water provinces: 1) the Basin and Range Lowlands covering the southern and vE>stern portions of the state, 2) the central Highlands covering the central mountain region, and 3) the Plateau

Uplands covering thP northern part of the State. These Provinces are shown on Map No. 502-B. The Basin and Range Lowlands Province includes the extensive desert areas that are the most populated, and where most of the agricultural activities occur; therefore, the highest demands on water resources are in this province. This provi nee is drained externally by the Colorado River and its main tributary, th~ Gila River.

:tI-8 The Central Highlands Province receives the highest amounts of precipitation. Also, it contains a perennial water supply that is the source of strea ■ flow to the lowlands. In this Province, the ftogollon Ria serYes as the ground water and surface water diYide between the Little

Colorado River in the Uplands and the Salt River syste ■ in the Lowlands.

The Plateau Uplands ProYince is seaiarid thus receiving only small amounts of precipitation. .Plost of the ■ oisture from rainfall is lost through evaporation, and streams yield very little water in proportion to the size of the drainage area. Principal drainage is provided by the Little Colorado River that cuts through the heart of the Province to the Colorado River.

"ap Ho. 502-B also shows the average depth to groundwater, in 1975. In respect to this subject, the

Arizona Water coamission in its report "Phase II, Arizona State Water Plan, Alternative Futures" stated that 60 percent of the total aaount of water used in the State, in

1970, was fro• groundwater supplies estimated to be in excess of 1.2 billion acre feet. Further, the report stated, "At the 1970 level of develop ■ ent, groundwater resources were being depleted at a rate of about 2,200,000 acre feet each year, whereas the natural replenish ■ent vas only about 300,000 acre feet. Unfortunately, depletion of the ■ assive underground reservoirs cannot continue forever."

II-9 Note: An acre foot of water equals 325,850 gallons. As a result of this critical situation, water conservation, development, and management policies and programs are being carefully formulated/monitored by the Water commission. This has resulted in improved methods of vat.er usage, and the implementation of pollution controls.

*Note: A deposit is a measurable and quantifiable existence of a mineral; an occurrence is a finding or happening with no measurement for existence in quantity.

Statistics, 1970 and 1975•.

Table Bo. 503 is diYided into six general categories of land ownership custoaarily used by various public and private agencies. Additionally, the Table is detailed to county level for co ■ parati ve purposes. The six categories with their respective percentage of land ownership are: 1. u.s. National Forest SerYice 15. 91

2. o.s. Borea u of Land rtanageaent 16.71

3. Indian Reservations 26.6% "· State of Arizona 12.8% 5. Individual or Corporate 18.01

6. Other 10.0%

TOTAL 100.01

The category •other• includes land adainistered by the National Park Service, Departaent of Defense, Bureau of

Sport Fisheries and Wildlife, Bureau of Recla ■ ation, and other miscellaneous public land (Federal, State, and county).

lI-16: The category "Indi 11idual or corporate" is included in order to give a total indication of land distribution within the State. and to account for the land that is subject to possible future private development.

The previously ■ entioned percentages reveal that 82 percent of the land area within the State is owned or administered by a governaental agency (including Indian

Coamunities) while only 18 percent of the land area--less th.an one-f ifth--is in indi•idual or corporate ownership.

Plore specifically, the land area of the State totals

72.688,000 acres that equals approximately 113,000 square miles of land. This means that overall there are about

13,000,000 acres (about 20,300 sq. mi.) of private or corporate land for possible development. Interestingly, this aaount of land approximates the combined area of the

States of Connecticut, Nev Hampshire, and Nev Jersey.

Between 1970 and 1975, the amount of private lands increased by approximately 550,000 acres (about 95q sq. mi.).

It is readily apparent that privately-owned land is a key resource where most urban developaent is likely to occur; consequently, the use and development of priYate land should be closely 11oni tored as the state Transportation Plan evolves. Land ownership and/or administration of land is a prime factor in determining priori ties. for the developaent of the

State Transportation Plan. While a huge portion of the

II-17 State is owned or adainistered by a governmental agency, it must be emphasized that public lands pri ■ arily serve the needs of people in terms of employment, aineral and forest products, grazing, recreation, enYiron ■ ental preservation, and the like. Rap No. 503-A shows the general location of the previously-mentioned land ownership categories. !ap No.

503-8 shows a ■ ore detailed delineation of most lands owned or administered by the Federal Government.

Agriculture has been and continues to be a significant land use that contributes to the growth and financial stability of the State. More specifically, agriculture, through the movement of products and employment, has a considerable impact on the State transportation system. For purposes of this report, three tables and a map vere prepared to reflect the following information: I. Type of Activity A. Cropland

1. Vegetable 2. Citrus 3. Field Crops B. Livestock

1.. Cattle 2. Sheep 3. Hogs

4.. Poultry

II. Statistics by county and the State for 1969 and 1974 as published in the u.s. Census of Agriculture. III. General location of irrigated farmland in each county, and soils suitable for irrigation are shown on Map No. 504. The o. s. Census of Agriculture has been conducted every five years since 1959, under the provisions of Title 13,

United States Code section 142(a). For this report, statistics from the 1969 and 1974 census reports were used for comparison. Additional statistics were obtained from the Statistical Abstract of Arizona and the Arizona

Department of Economic security. Information published in the 1974 u.s. census of Agriculture indicated that approximately 53 percent of the land within the state was defined as land devoted to farming. This amounted to 38,544,116 acres. The figures are misleading since 37,321,446 acres of land are attributable to the National Forests for growing trees and forest preservation. Actually, only 1,222,690 acres were used for the growing of crops and the raising of livestock.

The total acreage vithin the State is 72,688,000; therefore, only 1.7 percent of the land within the state was, in fact, used for the growing of crops and raising livestock.

Specifically, Table No. 504-A reveals that 712 new farms were established during the five-year period between

1969 and 1974: yet, there was a slight decrease in the amount of land devoted to farming. specifically, 18,592 acres vere added to harvested cropland, while 21,679 acres were re ■ oYed from the a ■ ount of land devoted to raising livestock. In addition, the acreage of irrigated land was reduced by 23,835 ~cres or about 2 percent.

II-24 Table No. 504-B contains dat.a on genera 1 characteristics of farms by county. Column 3 (Total Acres

Farmed) also includes forest lands as recorded by the u.s.

Census of Agricultur~. Column 4 (Acres of Harvested

Cropland} and Column 5 (Acres for Livestock) provide a truer indication of agricultural activities in each county and for the state.

Table Mo. 504-C contains a division of the number of farms devoted to selected crop and livestock activities.

Cropland activity general! y increased in the five-year period with the exception of farms devoted to the growing of vegetables, in which acreag~ was reduced from 87,968 to

59,591 or 32 percent. Livestock activit.y also increased generally. The exceptions in this activity were the reduction in the number of farms raising sheep from 322 to

297; yet, the number of sheep increased by 46,157. An interesting statistic in this table is that the number of farms devoted to raising poultry increased by 351 from 530 to 881, but the pr1>duction of poultry vas significantly reduced by 347,582 or 30 percent.

Arizona's population is located primarily in urban

areas. As defined by the United States Bureau of the

Census, the urban population comprises all persons residing

in places incorporated or unincorporated which had 2,500 inhabitants or more. From 1950 to 1975, the proportion of the state's population living in urban areas has increased significantly--from 56 percent to 80 percent. Nov, four out

of five persons in the State live in urban areas. Recent increases in the State's population have been

concentrated in the two major urban areas of Phoenix and Tucson. Approximately 80 percent of the State's population

growth for the period 1950-1975 occurred in these two major

urban areas. In 1976, as shown in Table No. 505, the urbanized area population of Phoenix reached approximately

1,158,000 and Tucson•s approximately 341,000. As a result,

almost two-thirds of the State's population resided in these

two urbanized areas. Currently, the State has only two minor urban areas; that is, cities with a population of 25,000 to 50,000 persons. Flagstaff is the State's third largest urban area.

1976 population estimates, prepared by the Arizona Department of Economic Security, indicate that over 32,000 persons live there. The fourth largest urban area, Yuma,

had a 1976 population estimate of about 31,000.

II-30 Table Ro. 505 also lists over thirty saall urban areas with populations of 2,500 to 25,000 persons. 1976 population esti ■ ates for these areas were also obtained fro ■ the Arizona Department of Economic security (DBS). These figures represent only the population within the corporate li ■ its of the cities and towns. In some cases, several communities have been grouped together as one urban area.

For example, ftia ■ i, Globe, and Claypool fora one continuous small urban area. ftap Ho. 505 shows the generalized location of urban areas in 1976.

By the year 2000, Arizona• s population, according to DES• latest projections, will reach 4,032,200. Seventy-six percent of that population is expected to be .in Maricopa and

Pi ■ a Counties; therefore, the State's population is expected to remain highly urbanized.

The State of Arizona has nuaerous archaeological and

historic sites. The transportation planning process should consider these sites to the extent that transportation goals should be consistent with the preservation of historic

sites.' The National Historic Preservation Act of 1966 mandates:

• • • (b) that the historic and cultural foundations of t.he Nation should be preserved as a

living part of oar comaunity life • • • in order to give a sense of orientation to the American people; (c) that, in the face of ever increasing extensions of

urban centers, highways, and residential, co■■ ercial, and industrial developments, the present historic

preservation programs are inadequate • • • In the sa ■ e

year,, Section 4 (f) of the Department of Transportation

Act requires that the Secretary of Transportation make

"a special effort • • • to preserve ••• historic

sites" and to refrain fro■ approving any program or project "which requires the use . . . of ••• any land

fro• a historic site ••• "• In light of these responsibilities for historic preservation, a preliminary inventory of historic and

archaeological sites has been prepared fro ■ existing

sources. All the sites which are included in the National

II-36 Register of Historic Places, as of February 1977, are shown on ftap No. 506, entitled "Historic and Archaeological

Sites•. Both historic sites and historic districts are included in the National Register; reference to Appendi.x No.

506 is suggested. Historic sites represent individual buildings, structures, ruins, and the like. on the other hand, historic districts are geographically definable areas of varying sizes such as a neighborhood or central business district. Selected archaeological sites are also shown on

Kap No. 506. s011e of these sites are included in tne National Register of Historic Places and have public displays. The state has thousands of other archaeological sites which are not shown on this map. These sites are recorded primarily by three major institutions: Arizona

State Museum at the University of Arizona, Arizona State University, and the Museum of Northern Arizona. The State

Historic Preservation Officer has ready access to these site files. Most of these sites are not open to the public. unnecessary public exposure to unexplored sites often leads to vandalism of the site and theft of artifacts. Importantly, transportation planners should be aware of the existence of these sites and should ma Ice every effort to preserve the sites whenever possible. Moreover, the selection process for transportation corridors a·nd right-of

ways should include close coordination vith the State

Historic Preservation Officer. Prior to the selection of

II-37 the corridor, the planning process should include an inventory of historic resources. This broa·d based type of survey aay help to prevent future probleas and delays, as well as possibly save expensive site acquisition costs.

The location of individual ghost tovns and concentrations of ghost towns has also been included on Kap

No. 506. Kost of the ghost tovns are not on the National

Register of Historic Places, but they do represent a significant part of Arizona's history. care should be exercised before planning to build major transportation facilities through these sites. A consideration of these sites will help to preserve those that aay have important historic significance. One final note: In conjunction with the o.s. Army corps of Engineers planning program for water resource development in the Phoenix Metropolitan Area, two important surveys have been completed. The first is A Regional

Archaeological overview of the Phoenix Metropolitan Area, and the second is An Initial Survey of Historic Resources

Within the Phoenix Metropolitan Area. Both studies should be exa ■ ined when planning for any transportation facilities in Maricopa County.

This land feature refers to topographic slope, a feature of importance in determining transportation corridors, specific routes, and potential construction sites. Most of the following paragraphs containing descriptive background information were extracted from a planning report, prepared by the Alabama State Planning Division, entitled "Planning Consideration: Topography and Slope". Topography is the general configuration or shape of the land surface, including the position of the physical characteristics of the terrain. A topographic map shows the relative position and characteristics of natural features, such as mountains, valleys, streams, and such manmade features as roads, bridges, buildings, and other prominent features. The basic information shown on a topographic map is the contour lines that represent the difference between land elevation. A contour line is defined as an imaginary line on th~ ground, every point of which is at the same altitude or elevation above sea level. Contour lines on a map are simply the graphic representations of ground contours. The lines are drawn at any specific elevations or intervals-of equal elevation changes such as S, 10, 20, 100, 200, etc., feet above mean sea level. A series of contour lines

II-40 provides a visual impression of topography, and supplies accurate information about true elevations and slopes.

A contour interval is the vertical distance between successive contours with the interval remaining constant over an entire map. Since the vertical contour is fixed, horizontal spacing of contours varies with changes in land slope. Although the map legend will describe the full information on the contour intervals used, the general rule for interpreting contour intervals is that a close crowding of contour lines represents a steep slope while wide spacing represents a gentle slope. This is exemplified by Appendix

No. 507-A. It should also be mentioned that topographic maps showing regions of strong relief require a large spacing interval e.g., 50,100, or 200 feet: regions of moderate relief, intervals such as 10 or 25 feet. The most widely used topographic maps are prepared by the United States Geological Survey that makes a series of standard topographic maps to cover the United States. The

Demography and Land Use Section has on file an Index to topographic maps of Arizona that show the status of topographic mapping in the State, and the scale at which the maps are available. Slope is defined as the gradient of the land surface and is measured as either a percent, an angle, or as a ratio. A diagrammatic representation is shown in Appendix

No. 507-B. Slope maps are prepared from topographic maps, with greater accuracy added by using aerial photographs and field inspection data measurements. Slope is best understood within the context of the topography of the land area under study. For instance, two areas may both be flat: yet, if one area lies near a stream, it is subject to flooding while the other area that is atop a plateau, has no such problem. Thus, for use in land planning one must know not only the slope of the land, but also its location or topographic position. Slope maps are of greatest use for individual parcels of land under study. The slope map swmnarizes slope information by grouping local areas with similar slope values into single map units. When used in conjunction with geologic, vegetative, soil, highway, and a variety of other maps, slope maps are valuable tools in. evaluating environmental factors and land use potential that are critical to sound development. Map No. 507 depicts selected physical features and land forms of the State. In particular, the map shows in a very general manner the land form regions, mountains, valleys, and rivers. Because of the variations of the terrain and soils, detailed analysis should be accomplished on a site specific basis when specific transportation routes are to be determined.

In Arizona, both land subsidence and earth fissures are directly attributable to water-level declines resulting from large-scale groundwater withdrawal. Earth fissures--as explained by H. H. Schwnann--"generally first appear as long narrow linear features less than 1 inch wide and as much as 1 mile long. When irrigation water is applied, or following rainstorms, the fissures intercept overland flow and act as drains. Erosion caused ·by water draining into the fissures causes them to widen rapidly to as much as 30 feet at the land surface. In some places, land has differentially subsided more on one side of a fissure than on the other side. The fissures are confined to the alluvial deposits and have not been observed in the adjacent bedrock outcrops." At this time, only a portion of the State has been studied. for the existence of subsidence and fissures. Specifically, studies were made in parts of Maricopa and Pinal Counties in Central Arizona. In addition, fissures have been observed and plotted in the Willcox and San Simon areas of Cochise County. Measurement of land subsidence is based on adjusted u.s. Coast and Geodetic Survey level data, or estimated. In the latter case, it is necessary to account for water-level declines, geohydrologic data; and

II-44 geophysical data. The extent of the problem is highlighted by these statistics: 1. Measured, maximum subsidence between 1948 and 1967 approximated 7.5 feet, near the Town of Eloy. 2. Measured, maximum subsidence from 1967 to 1975, approximated 3.05 feet, near the community of Picacho. Land subsidence and earth fissures have damaged agricultural lands, irrigation systems, water wells, structures, and transportation facilities. Occurrences of land subsidence and earth fissures warrant careful attention including field surveying, particularly in site-specific developments. Note: The impacts of land subsidence and earth fissures are significant enough to warrant reference to Appendix No. 508, a paper prepared by Carl c. Winikka and Paul D. Wold, and presented at a symposium in December 1976. A final note: Map No. 508 is included because subsidence is ~ttributed to water-level declines. In particular, this map shows the change in groundwater-levels for the period between 1940 and 1972. Further, a close review reveals that significant declines in water-levels are occurring in heavily irrigated areas of the State. An interesting note is the rise in water-levels in two areas of southern Yuma County.

l 1973 Arizona Water Coa ■ ission report contained the following releYant statements in reference to floodplains:

"In Arizona, tvo distinct types of land areas are subject to flooding: floodplains and alluvial fans. The floodplains include the flat, lov-lying a~eas associated vith the major drainage systeas in the State.

"The alluYial fans that spread out at the base of the desert mountains have poorly defined drainage patterns.

"Recent studies have shown that runoff increases over

300 percent when desert lands a.re developed for residential and coaaercial uses. continued deYelopment, therefore, increases the flood problems which already exist for dovnstrea ■ areas." Runoff is increased when the land is built or paved oYer. This decreases the ground's ability to absorb moisture. Streets often amount for one-sixth to one-third of the total urban area; therefore, street construction significantly alters runoff. In addition, urban development often changes or destroys the natural drainage channels.

A significant aaount of the inhabited areas of Arizona are subject to flooding. Oyer time, the economic and social costs of these floods have been increasing. Flood damages in 1965 were estiaated at $38 •t~lion (1965 dollars), by a joint federal-state study. In. 1972, flood damage in the

Il-4-7 urban areas of !laricopa county alone was esti11a.ted at al■ ost

$11 aillion. These damages are not restricted only to buildings. Transportation facilities, especially bridges, are subject to flood daaage. In response to these increasing flood costs, the

Arizona water Coaaission, in 1973, prepared a statewide floodplain area aap which shows the areas subject to a 100- year flood. These flood-prone areas have a 1 in 100 chance on the average of being flooded during any year. This aap was based upon data from the United states corps of

Engineers, the United States Geological survey, and the United States Soil conservation Service. While this map doesn't shov all of the 100-year floodplains within the state, it is the only available statewide floodplain aap (see !ap No. 509). At this time, the o.s. Department of Housing and Urban Development, through the Federal Insurance Administration is engaged in a detailed flood mapping program. Numerous coaaunities in Arizona have had or are contracting for detailed floodplain maps {see Appendix wo. 509). Copies of the completed aaps are aYailable fro ■ the Arizona state Land Departaent..

III--1 NO. 101: MAJOR MANUFACTURING ESTABLISHMENTS

In Arizona, direct manufacturing output accounts for about 13 percent of total gross state product. In 1975,

this amounted to approximately 1.46 billion dollars (19'72 constant dollars). Manufact~ring employment in 1976 was 99,900, about 12 percent of total Arizona employment. The manufacturing sector, as defined by the Standard Industrial Classification system, covers a broad range of products.

This diversity is represented by Arizona industries which range from food processing to sophisticated electronic component and scientific instrument production. While manufacturing activity generally occurs statewide, the majority takes place within the two urban counties. In 1976, Department of Economic Security (DES) estimates for total annual average manufacturing employment were 72,900 (73 percent) and 12,100 (12 percent) for Maricopa and Pima Counties, respectively. The residual of 14,900 (15 percent) is distributed among the non-urban counties. Table No.'s 101-A, 101-B, and 101-C summarize major non-urban and urban concentrations of manufacturing activity by sector derived from the 1977 Arizona Survey of Manufacturing and DES data. Map No.'s 101-A, 101-B, and 101-C contain the same information.

The ability to distribute goods and services and

transport freight and passengers is a characteristic of

advanced economies. The Arizona economy is heavily dependent upon efficient transportation because of spatial considerations. Most Arizona communities are serviced by a variety of transportation facilities including bus, rail,

air, and motor transport service. These capabilities are instrumental in encouraging healthy economic interaction and

the attraction of new industry. Map No. 102 presents a summary of available rail, both passenger and freight, bus, and motor transport services for communities (regions) with

significant economic activities.

by the U.S. Bureau of Census, Census of Governments, 1972,

Volume 1, Governmental Organization. It is believed that

this information may be of value in order to assess

transportation needs throughout the State.

As defined in Volume 1, Governmental Organization,

there are 406 local governments in the State. They were

divided in the following manner in 1972:

Counties 14 Municipalities 65

School Districts 237

Special Districts 90

Total 406

For purposes of this report, Headquarters, as listed in

Table No~ 103, were limited to the appropriate county seat where federal, state, county, and municipal governmental

activities are usually centered.

Map No. 103 shows the general location of those municipalities with major governmental headquarters.

For informative purposes, data related to Indian

Community Headquarters was obtained from a publication by the u.s. Department of Commerce, entitled "Federal and State Indian Reservations and Indian Trust Areas", 1974.

For purposes of this report, the information presented is primarily limited to data published by the State

Department of Health Services (on Arizona Licensed Non-

Federal Hospitals), the State Department of Public Safety, and responses obtained from individual hospital administrators.

Hospitals may be viewed as a land use activity that ideally provides for the health, safety, and general welfare of a local population. As a result, significant attention must be given to the inclusion of hospital requirements in the development of the State Transportation Plan. Such consideration would focus on all facets of access.

Table No. 104 shows that at least one hospital exists in each county. All of the hospitals in Maricopa and Pima

Counties were not included, in conformity with user agreed to criteria. In these two metropolitan counties, only those nospitals that provide emergency air service and/or specialized treat~nt, such as the Maricopa County Burn

Center or Barrows Neurological Center were included. In the non-metropolitan counties, all non-federal hospitals were listed. Also, reference should be made to Map No. 104 that shows the general location of listed hospitals. The amount of land provided for each hospital varies from three acres for the hospital at Morenci in Greenlee

III-15 County to 120 acres for the hospital at Nogales in Santa

Cruz County. An average of 21.4 acres per hospital is provided for the hospitals listed. In most instances, the amount of parking provided is equal to twice the number of beds per hospital.

Emergency air service is provided on hospital sites in six counties. This air service appears to be strategically located as evidenced by scanning Map No. 104.

In addition to the foregoing, the U.S. Veterans

Administration operates hospitals in Phoenix, Tucson, and

Prescott. The Indian Health Service also operates eleven hospitals throughout the State. These are located in Tuba

City, Fort Defiance, Winslow, Parker, Yuma, Phoenix,

Sacaton, Whiteriver, San Carlos, Sells, and Keams Canyon.

These hospitals are also shown on Map No. 104.,

The State supported system of highei: education in

Arizona is composed of two administrative units. One unit is the State Board of Begents that oversees the three State Universities. The state Board of Directors for community

Colleges is the other unit, and it controls 14 community colleges on 22 campuses.

Two of the State•s universities are located in the two most populous counties. Arizona State University, with a total student enrollment of 34,400 students in 1976, is located in Maricopa County. The University of Arizona, which in 1976 had an enrollment of 28,400 students, is located in Pima County. The third State University,

Northern Arizona University, is located in Flagstaff; its enrollment reached 10,600 total students. These three universities, because of their size alone, signi.ficantly impact the state transportation system.

over 73,000 total students

over 15,000 full and part-time employees

over 57,000 registered motor vehicles

The State Community College system is composed of 22 campuses; however, many of these are too small to significantly impact the state transportation system.

III-19 For the purpose of this study, standards for impacts of major urban area community colleges are different than that for rural area colleges.

Major Orban Areas: Community Colleges with 10,000 or more total students.

Rural Areas: Community Colleges with 2,500 or

■ ore total students. Based upon these criteria, four coaaunity colleges have statewide impacts in the tvo 11ajor urban areas; three of these colleges are in Maricopa county, and one is in Pima

County. on the other hand, only four rural area community colleges have sta tevide impacts because of their student body size. These are located in Cochise, Pinal, Yavapai, and Yuma Counties. Enrollments at the other six community colleges are not large enough to create any significant statewide transportation impacts. Campuses for these si.x colleges (including branch campuses) are located in Bullhead City,

Thatcher, Holbrook, Globe, Show Low, Kingman, Snowflake,

Lake Havasu City, Winslow, and Winkelman. In addition, two schools are located on the Navajo Indian Reservation; however, neither the College of Ganado nor the lavajo Co1111unity College (at Tsaile) had enrollments of 2,500 students.

III-20 A final note: ·rdble No. 105 contains a variety of pertinent statistics; Map No. 105 shows the generalized location of the listed education centers.

For transportation planning purposes, the aggregation of economic activity is an important determinant of traffic concentrations. In order to effectively plan for required improvements or extensions of facilities, planners need an accurate picture of the location and sizes of these industrial complexes. Table 106-A and Map No. 106-A present these data for communities outside of Maricopa and Pima Counties. The acreage data represents approximate totals where more than one industrial park exists. Listed areas represent parks with full utility and transportation services. Table No.'s 106-B and 106-C and Map No.'s 106-B and 106-C present similar data for the Phoenix and Tucson Metropolitan areas.

Mining is an important economic activity in Arizona and one which requires extensive transportation facilities for ore, materials, and finished product distribution. In 1975, total direct mining output of 545.18 million dollars {1972 constant dollars) amounted to 5 percent of total state output. Mining employment in 1976 was about 23,000 {2.8 percent of total state employment) • Mining activity is generally dispersed around the State although several counties have higher concentrations. The majority of activity is associated with copper production; however, other materials such as coal and uranium are also important. Table No. 107 summarizes major producing mining operations.

The specific concentrations of producers can be readily identified on Map No. 107.

Arizona's growing population and economy are placing increasing demand upon available electrical power generating capabilities. However, the utilities affected are engaging in substantial expansion to increase their ability to satisfy increased demand for services. Currently, several large scale power generation faciliti~s are either beinq constructed or are entering early construction phases.

These include coal-fired steam plants at St. Johns and

Springerville, and the Palo Verde Nuclear Plant west of

Phoenix. These projects, primarily the result of cooperation among major electrical producers, will increase the available electrical power supply for Arizona's future activities. Table No. 108 presents a detailed description of relevant data concerning the existing and planned power generating facilities. Map Ho. 108 presents similar data.

Arizona entered the aviation era with the establishment of the Nation's first municipal airport at Tucson. This was followed by another national "first" when Douglas Municipal

Airport vas designated as the Nation's earliest

International Airport. Scheduled airline service was provided by tri-veekly flights between Tucson, Phoenix, and

Los Angeles in 1927. This initial interest in aviation has carried through to the present time with Arizona now having the highest percentage of aircraft and pilots, on a per capita basis, in the Nation.

Public use airports in the State vary from large air carrier facilities, such as Phoenix-Sky Harbor International and Tucson International, to small municipal airports providing service to rural communities. Note: Table No.

109 lists these airports, plus military airports; Map No.

109 shows the generalized location of these facilities.

The larger airports provide a base of operations for as many as 500 general aviation aircraft. A large number of the smaller airports provide complete mechanical services including major engine overhaul while other airports provide only tie-down areas and are unattended. Complete information on all airports can be secured by contacting the

Arizona Department of Transportation, Aeronautics Division

III-46 or any Federal Aviation Administration Flight Service

Station.

The previously-mentioned map does not indicat~ the numerous privately owned-private use airports. This information changes on a monthly basis with new rudimentary airstrips constructed to serve ranches, farms or "duster" operations, and with many of these facilities being abandoned or relocated after short-term use. since these airstrips are transitory and are not available for public use, a determination was made not to show them.

When mentioning aviation in Arizona, it is appropriate to point out the varying meteorological and geographic conditions which make our airports and flying conditions unique. With summer temperatures well in excess of 100 F.

~38 C.) and many airport elevations over 6,000 feet above sea level, it is not unusual to reach density altitudes

(i.e., altitude corrected for non-standard temperature) in

excess of 11,000 feet. such extremes severely restrict normal aircraft performance and have dictated that many

Arizona airports provide what may be considered to be long runways to compensate for this condition.

This phenomenon coupled with fast moving weather

fronts, thunderstorms, dust storms, and vast unpopulated

areas places heavy emphasis en the requirement for adequate

airport and air navigational facilities. The airport system

shows on Map No. 109 will be expanded with new airports now

III-47 in the planning stage. To illustrate: new airports are now under active consideration in both the Tucson and Phoenix areas. Possible airport relocation is also being considered by some smaller municipalities in order to provide more adequate airport facilities. Planning for this expansion is now under1itay with the preparation of local airport master plans, regional airport system plans, and an updating of the 1973 State Airport systems Plan.

III-54 NO. 111: MAJOR CULTURAL AND SPECTATOR FACILITIES

Most of the State•s major cultural facilities are located in the Phoenix and Tucson metropolitan areas. Major cultural facilities which annually attract millions of visitors and spectators include museums, observatories, zoos, botanical gardens, stadiums and arenas, civic centers, race tracks, and a mission. All of these facilities are listed on Table No. 111-A and are shown on Map No. 111.

Over twenty major cultural facilities are located in the Phoenix metropolitan area, and they are listed on Table

No. 111-B. Facilities such as the Heard and Phoenix Art

Museums, the Phoenix Zoo, and the Desert Botanical Garden annually attract numerous visitors. For example, the zoo attracted about 500,000 visitors in 1976. Many stadiums and arenas in this area are home-base for professional baseball, basketball, hockey, volleyball, and tennis, as well as college sports. The Arizona state University stadium currently has a seating capacity of about 58,000; planned expansion (by 1978) will increase that capacity to about 70,000. In addition, during the 1975-76 racing season horse and dog tracks attracted over 1,000,000 spectators.

Compared to the Phoenix area, the Tucson metropolitan area has the State's next highest concentratiorr of major cultural facilities. Table No. 111-B also lists the major facilities which are located in this area. Several

III-55 facilities i.e. University of Arizona Stadium, McKale

Auditorium, and the Arizona Historical Society Museum are located on the University of Arizona Campus. The Historic

Society facility lacks satisfactory public parking and is trapped in the general traffic congestion of the University.

Annual visi.tations at this facility have been severely limited because of these two problems. As in Phoenix,

Tucson's Zoo attracted many visitors, 270,000 visitors in

1976. Tucson's most popular cultural facility has been the

Arizona-Sonora Desert Museum. Located fourteen miles west of Interstate 10, this facility had 370,000 visitors in

1976, and is expecting over 450,000 visitors in 1977. In addition, Tucson has a civic center complex with an exhibition hall, assembly hall, and a music hall. Other cultural facilities include an art museum, a baseball stadium, and a race track.

Several museums are located in other parts of the

State. The Museum of Northern Arizona in Flagstaff attracts about 100,000 annual visitors. Another popular museum, the

Sharlot Hall Museum, is located in Prescott.

Two nationally famous observatories are located in

Arizona. One is the Kitt Peak Observatory that is located west of Tucson, and had visitations in 1976 approximating

80,000 persons. The second observatory is located in

Flagstaff. This is the Lowell Observatory that attracts only about 10,000 visitors annually because of its lack of

III-56 parking and public restrooms. The observatory expects to

remedy this situation if financial support can be found.

The completion of these facilities could lead to a dramatic

increase in visitations to this observatory.

Horse, dog, and auto racing are major spectator sports

in Arizona. Thase race tracks attracted over 2,000,000 spectators during tne 1975-1976 racing season. Many of

these tracks are located in Maricopa County; however, several are located in other parts of the State. To

illustrate, tracks are located in Prescott, Amado, Apache

Junction, Rillito, and Yuma. The limited racing season for

each track is shown in Table No. 111-A.

As with other major activity centers, major cultural

facili~ies create significant impacts upon the State and

local transportation systems. Most people use their private

automobil~s to get to these facilities. As a result, they

drive millions of miles. Substantial parking facilities are

needed to handle peak crowds at such popular events as

college football games, horseracing, and dog racing. On the

other hand, some cultural facilities are hindered by a lack

of parking or convenient access. In addition, many segments

of the population, because of age or income or other

nandicaps are probably unable to visit many of these

facilities. Major cultural facilities are an asset to any

community, but these facilities can become a burden to the

III-57 community because of traffic congestion and parking problems, inherent with any major activity.

A final note: Table No. 111-A is a listing of all major cultural facilities in Arizona, while Table no. 111-B summarizes this data by community and is keyed into Map No.

111. This data doesn't represent all cultural facilities throughout the State. Many small museums, historical societies, and county fairs hcve facilities in various parts of Arizona, but the attendance at these facilities is not considered to have a significant impact on the State transportation system.

Tourism is one of Arizona •s leading industries. The State has been blessed with an abundance of outstanding scenic at tractions as well as a weal th of historic places. Arizona residents and tourists are able to enjoy many national parks and recreation areas, national monuments, and state and regional parks. The Grand Canyon, Arizona's most famous scenic attraction, had over 3,000,000 visitors in 1976. Other major parks and recreation areas attracted over

22 million visitors in 1976. Arizona has aore National Park Service Areas than any other state. The National Park Service maintains 24 service areas in the State, which includes two National Parks, two

National Recreation areas, two National Historic Sites, one

National Memorial, and 17 National Monuments. Eleven of these areas and monuments, each attracted over 100,000 visitors in 1q16. These eleven National Park Service

Facilities which are shown in Table No. 112, have created significant transportation impacts for the State. These areas total almost 7,800 square miles of land and attracted almost 15 million visitors in 1976.

The National Forest Service administers over 18,000 square miles of land in Arizona or about 16 percent of the

State•s total land area. Kuch of this land area is used for recreational purposes. Major recreation areas with over 100,000 visitations in 1976 are located in the following National Forests: Apache-sitgreaves, coccnino, Coronado, Kaibab, and Tonto. Table 112 lists the 13 specific areas which each attracted over 100,000 visitations. All of these areas combined attracted almost 5 million visitors in 1976. Specifically, Oak Creak canyon Vista and Slide Rock (in Coconino County) attracted about 850,000 visitors while Mt.

Lemmon (near Tucson) attracted over 1,000,000 visitors. In addition, the Salt River Lakes area in the Tonto National Forest is a prime recreational area. While visitation data i~ difficult to obtain for just the lakes, it is estimated that these lakes (Saguaro, Canyon, Apache, and Roosevelt) probably attract over two million visitors fer year. Currently, the Arizona State Park system consists of 15 facilities which include historic parks, recreation parks, and numerous lakes. Nine of these facilities each attracted over 50,000 visitors in 1976. Although these areas have had major transportation impacts, the magnitude of these impacts is considerably less than that of the federal park facilities. These nine state parks approximate 37 square miles of land; and in 1976, they attracted almost 2 million visitors. Significantly, Lake Havasu State Park had 880,000 visitorsr nearly one-half of all visitations to the state parks. The other major state parks are list~d in Table No. 112 and shown on Map No. 112.

III-68 Most regional and large county parks are located near the Phoenix and Tucson metropolitan areas. A total of ten

regional parks which each had 50,000 or more visitors pBr year are shown in Table No. 112. Six of these parks are located in Maricopa county, one is in Pima County, and three are in Koh-ave County. One of the Mohave County parks has just been opened and is expected to attract at least 50,000 visits annually. These ten parks comprise ever 150 square miles and attracted almost 3.5 million visitors in 1976. Almost 2.5 million persons visited the parks in Maricopa County and one million persons visited Tucson Mountain County Park. Further, Arizona has many scenic areas which attract many people. Specific visitation data is not available for these scenic areas; however, tourism is an important industry in places such as the Mogollon Rim, the White Mountains, Monument Valley, and along the Mexican Border.

For example, in 1975 almost 9 million persons crossed the

border at Nogales; many of these crossings are tourist related. Recreation and tourism have created a tremendous impact

upon the State of Arizona as well as its transportation system. The major parks and recreation areas experienced almost 25 million visitations in 1976. ~illions of motor vehicles, primarily automobiles, brought these people to the parks. Assuming an average of 3.5 persons per vehicle, then

IIT-69 over 7 million automobiles coulj have entered these park areas in 1976. It follows that hundreds of millions of vehicle miles were traveled in order for people to visit these parks. In addition, these major parks compris~ about 8,000 square miles of land area in the state. Finally, the location of these parks within the State is quite significant for transportation planning purposes. As shown on Map No. 112, except for the regional parks, most of these facilites are not located where the majority of Arizonans live. The federal parks are located primarily in the northern part of the State. State parks are mostly in the western part of the state and in other scattered rural areas. The Salt River lakes are the only major facilities, other than regional or county parks, which are relatively close to the Phoenix metropolitan area. Just one state park is in Maricopa County, and it attracted only 10,000 visitors in 1976. Most Arizonans must travel ~ignificant distances in order to visit the major parks within the state. About 20 percent of the State•s population lives in Pima County, but only two federal facilities are near the urbanized portion of the county. In the future, most Arizonans will still have to travel great distances to visit the State's major parks and recreation areas.

The 1975 Arizona State Water Plan indicated water which is stored in natural lakes and man-made reservoirs as well as the water which flows in creeks and rivers is all considered surface water. The development of surface water is influenced by climate, topography, elevation, vegetation, and geology of a particular drainage area. Arizona has approximately 440 lakes and reservoirs within its boundaries. Major systems of reservoirs have been constructed on the Colorado River by the Federal Government. In addition, major water storage systems are located on the Salt, Verde, Gila, and Agua Fria Rivers. Many smaller lakes are located along the Mogollon Rim and in the White Mountains. Table No. 113 shows 40 lakes which have an average surface acreage of at least 100 acres. For the purposes of this study, these 40 lakes and reservoirs are assumed to have the greatest impacts upon the state transportation system. The largest of these reservoirs are located on the Colorado, Salt, Verde, and Gila Rivers. Most of the man-made lakes and reservoirs, which are shown on Map No. 113-A, have been constructed for the purposes of flood control, water supply, irrigation, and electr.ic power. Other benefits have also included recreational uses, fish and wildlife habitats, silt retention, and municipal and industrial water supplies.

III-76 Arizona's rivers and creeks lie within three major drainage areas--the Lower Colorado Main Stem, Little Colorado, and Gila. While most rivers and creeks only flow intermittently, the Colorado River flows year-ro~d.

Several small tributaries of the Colorado River, primarily within the boundaries of the Grand Canyon, also flow year round. Most of the perennially flowing streams are found along the Mogollon Rim and in the White Mountains. These two areas receive considerably higher amounts of annual precipitation than do most other parts of the State. Finally, the southeastern portion of the State has several scattered pockets of perennial streams. Map No. 113-B, which was compiled by the Arizona Game and Fish Department, shows the location of perennial streams within Arizona. Numerous rivers and streams within Arizona have been classified as "navigable waters" under the jurisdiction of the Federal Water Pollution Control Act, as amended, 1972. Section 404 of this act, requires a u.s. Army Corps of Engineers permit for the discharge of dredged or fill material into any designated "navigable waters". This act apparently would regulate the construction of new transportation structures in navigable waters, as· shown on Map No. 113-C. A list of these designated navigable waters is contained in Appendix No. 113 of this report. Both perennial streams and navigable waters will have significant impacts upon the construction of transportation

III-77 structures and facilities. In addition, the transportation planning process should also include a consideration of the natural drainage system such as washes, arroyos, and other normally dry channels. Specific site designs have and should continue to include detailed drainage studies. At this time, no new major dams have been authorized for construction in Arizona. The Orme Dam has been deleted from the Central Arizona Project and another site has not been selected. Another reservoir to store CAP water could be authorized in the future, but no new sites have been selected. In addition, the San Carlos Apache Indian Community is considering a dam with a reservoir that could have an average surface acreage of 150 acres. Funds have not been appropriated for this project, therefore, this project is not a certainty.

The State of Arizona has a very rich history. Numerous ethnic groups have ■ade significant contributions to the development of the State. Their impact is reflected in the numerous special events vhich are held throughout the state.

These annual events are not only a reminder of Arizona's diverse cultural history, but the events are a aajor component of the State's tourist industry. Arizona's

Mexican, Indian, and frontier heritages are celebrated at

■any rodeos, parades, Indian pow vows, frontier days celebrations, and fairs.

Hundreds of events are held throughout the state; however, about twenty-five events attracted over 25,000 visitors each in recent years. In fact, some events have attendance figures of over 100,000 visitors; and the State

Fair, in 1976, attracted over 650,000 paid visitors. Table

No. 114 entitled "Major Special Events of Arizona" lists those events which attracted significant numbers of visitors. As shown in this Table, numerous events are held in the Phoenix and Tucson Metropolitan areas during the winter season. several events such as the state Fair, the

Parado del Sol, the Phoenix Jaycee Rodeo, and the Fiesta

Bowl Classic attract thousands of visitors from ih-state, as well as out-of-state.

III-85 In addition, several events he1d in the month of July have attained national attention. To illustrate, the Flagstaff All Indian Pov wow and the Prescott Frontier Days Bodeo and Parade annually attract hundreds of thousands of visitors.

All of these e.vents are i ■ portant to the State•s economy. Millions of dollars are spent for lodging, aeals, and other -expenses. On the other hand, these large events have created significant iapacts upon the State and local transportation systeas. ftany of these events are capable of producing aajor traffic tie-ups in Phoenix and Tucson. Purtheraore, other eyents can coapletely paralyze the highway syste■ in s ■ aller • unicipalities such as Flagstaff, Prescott, or Payson. Finally, adequate parking for thousands of aotor vehicles can beco ■ e a aajor obstacle to the success of ■ any of these events. These events can create unique transportation planning probleas because ■ ost transportation syste ■ s are built for average traffic volu ■es. In the worst instances, traffic congestion and the lack of parking ■ay threaten the future of these types of eYents.

III-90 NO. 116: MAJOR LUMBER AND TIMBER OPERATIONS

Although lumber, timber, and wood products operations constitute relatively small shares of total economic activity in Arizona--less than one percent of total employment--the characteristics of the products require heavy motor transport and rail services. In Arizona, these operations are generally located along the Mogollon Rim area from Williams to Springerville; however, other operations may be found statewide. These are detailed on Map No. 116.

In almost every case, the lumber and timber activity concerns small firms or larger organizations such as Kaibab

Industrie& with widely dispersed production; consequently, the concentrations of activity are generally minimal. Obvious exceptions include the pulp mills at Snowflake and

Flagstaff, and the Southwest Forest operations at McNary.

These particular operations have generally higher local impacts than the smaller concerns or groups. Table No. 116 presents the major producing operations or groups of firms

for the State.

Retail trade employment represents more than one-fifth of total employment in Arizona (22.13 percent 1976 Department of Economic Security estimates), and accounts for 17.5 percent of total gross state product. In terms of transportation planning activities, retail trade concentrations (e.g., shopping centers, etc.) present significant problems. In order to better anticipate future requirements for goods and people movements, planners desire an accurate picture of either present or future significant retail activities. For the urban areas, this requires the establishment of arbitrary size categories for accessing possible impacts. Map Nos. 117-B and 117-C present the geographical distribution of shopping areas with at least

100,000 square feet of floor space for the Phoenix and Tucson Metropolitan Areas. Table Nos. 117-B and 117-C present more detailed information for the same areas. Map No. 117-A and Table 117-A represent a summary of the non urban concentrations of retail trade activity.

1967. Between 1971 and 1975, approximately 1 foot of

subsidence was measured southeast of Mesa.

By 1964, large-scale pumping, principally for

irrigation, had lowered water levels more than 360 feet in

parts of the area, and numerous earth fissures were observed. Since 1964, water levels have declined more than

80 feet in local areas. Compaction-recorder data indicate

long-term water-level declines correspond with land

subsidence. Seasonal water-level fluctuations correspond with seasonal sediment compaction and expansion1 however,

the amount of compaction greatly exceeds the expansion.

Between April 1965 and April 1974, measured compaction in

the upper 830 feet of sediment in the Santa Cruz Basin near

Eloy accounts for 1.3 feet (62%) of the 2.1 feet total

surface subsidence at the compaction-recorder site.

Earth fissures, as much as 8 miles long, occur in the

alluvial sediments on the periphery of the subsiding areas,

transect natural drainageways, and act as drains. The

fissures intercept surface runoff in undeveloped areas, and

capture irrigation water traversing cultivated lands.

Downward and lateral water movement in the fissure causes rapid near-surface widening--partly by slumping but mainly

by erosion of the sides.

In 1976, renewed fissuring near the Picacho and Santan

Mountains and several areas of previously unmapped fissures

were mapped on orthophoto quads using a helicopter. New and

17 renewed fissuring, measured water-declines and sediment compaction, together with the limited leveling data available indicate land subsidence continues to occur over large areas of central Arizona.

Acknowledgments

Data presented were collected by persons from several agencies. The following assisted in mapping: Robert L.

Laney and Thomas L. Holzer of the U.S. Geological Survey1 Edward A. Nemecek and Phillip c. Briggs of the Arizona Water Commission. Robert L. Laney and his staff prepared the water-level declines maps. Richard H. Raymond of the bureau of Reclamation was of much assistance in all phases of gathering and interpreting data. Herbert H. Schumann of the u.s. Geological Survey furnished valuable background information.

Introduction

Major dams constructed on rivers in central Arizona provide the water necessary for extensive agricultural and industrial development. This development coupled with a mild, dry, sunny climate have made Arizona an increasingly more desirable place to live and development has continued at a rapid.pace. From 1970 to 1975, Arizona's increase in population was over 25 percent, the highest growth rate of any State in the Nation.

To meet water requirements of this growing area, ground-water is being pumped in addition to that supplied

18 through the reservoir system. The volume of ground-water withdrawn now greatly exceeds the rate of recharge. Land subsidence and earth fissures occurring in parts of central

Arizona are related to water level declines caused by large scale ground-water withdrawal (Figure 1).

Ground-water withdrawal in Arizona now exceeds the recharge by 2. 2 million acre feet per year, (Note: one acre foot equals 326,700 gallons of water). The Central Arizona

Project is expected to lessen this overdraft by approximately 1.2 million acre feet of water per year beginning in the 1980's. In the meantime, substantial subsidence and the intensification of earth fissuring in subsiding central Arizona basins is continuing. The Central

Arizona Project, new highway construction, and flood control projects will all be affected by this continuing subsidence process. Residential, industrial, and commercial expansion which follow will also be affected not only by the physcial hazards involved but also by the depreciation effect earth fissures have on property when occurring in or near development (Figure 2) or irrigated farmland (Figure 3).

At present, the extent to which declining ground-water levels, subsidence, and related earth fissures constitute environ.~ental hazards is minimal. Subsidence effects are gradual and take place generally in agricultural or undeveloped desert areas.

19 While fissures normally occur in natural desert areas they have also occurred across interstate highways, in irrigated fields, across pipelines, and frequently across unpaved local roads. In two known instances, earth fissures are in residential areas. Subsidence has caused the collapse of well casings and in some places apparent extrusion of well casings from the ground surface. Subsidence has thus required well replacement or modification. The subsidence process in Arizona transects both the scope and geographical extent of agency responsibilities. As a result, the total effects are not known and any assessment of the effects on ~uture projects requires a considerable data gathering effort. Records of subsidence are scarce· and existing level lines must be carefully evaluated prior to use for subsidence measurements. A continuity of elevation change measurements is made increasingly difficuit due to the destruction of bench marks and the rising cost of field surveys. Earth fissures not shown on existing maps were discovered during studies for the Bureau of Reclamation's Central Arizona Project. Other interested Federal and State agencies, with a common need for this information, joined the Bureau of Reclamation in mapping all visible earth fissures in the 800 square mile area in three major bas·ins south and east of Phoenix, Arizona (Figure 1).

The same fissure (right) in a vertical aerial photograph taken in June 1974. Note land taken out of production and exten sion of fissure toward top of photograph. This paper reports on a joint effort by several agencies to update and bring together information to better understand the interrelationship between ground-water declines, subsidence, and earth fissures. Techniques Mapping of the earth fissures was done in two stages. First, l:24,000 and larger scale color infrared aerial photographs were taken of all known fissure areas. A total of 144 aerial photographs were obtained. The aircraft and camera were provided by Arizona Department of Transportation and the film by the u. s. Geological Survey. All identified fissures, as well as probable fissures, were transferred from this photography to 1:24,000 scale orthophotoquads (Winikka-Morse 1974) furnished by the Arizona Resources Information System. Second, these fissures were checked and the entire area of approximately 800 square miles was searched by two observers and a recorder in a four place helicopter. Fissures were spotted from the air and checked on the ground. Locations were determined by using the orthophotoquads as base sheets. This procedure took three days for a total of about 15 hours flying time. Ground-water decline and measured subsidence information was gathered from ·state and Federal agency records. Recent information was found to be available from

24 the u. s. Geological Survey and the Arizona Department of Transportation. Water-Level Declines

Substantial water-level declines are continuing in a number of ground-water dependent areas in central Arizona

(Laney-in preparation). While these areas are predominantly agricultural, urban areas are not excluded (Figure 1).

Maximum values of water-level decline are 460 feet near

Stanfield, 360 feet east of Mesa, 320 feet southeast of Eloy, south of Queen Creek, and at Scottsdale. The decline at Scottsdale is recent, having occurred since 1952 (USBR-in preparation). In all of the above areas declines are increasing in magnitude and in total area affected.

Subsidence Land subsidence in Arizona related to ground-water withdrawal (Poland-Schumann 1969) is continuing. Subsidence has a relationship to ground-water declines in the Casa

Grande-Pic.acho section of Pinal County (Figure 4). When declines and subsidence are plotted against time, a strong linear relationship is found at Picacho (Figures 5 and 6). Information available on four bench marks in the

Toltec-Eloy area of Pinal County shows subsidence of these marks from 1960 to 1975 to range from 1.4 feet to 2.2 feet. In the Picacho area several marks have subsided more than 2.3 feet from 1967 to 1975 with the result that the area of maximum measured subsidence has shifted approximately 3.5

25 miles southeasterly along the Casa Grande-Picacho Peak profile since 1967 (Figure 4). The maximum known subsidence measured in Arizona between 1967 and 1975 has occurred at Picacho where a 1967 National Geodetic Survey Bench Mark, X363, subsided 3.05 feet. During that same time period, other marks in the area subsided by amounts exceeding 2.3 feet as illustrated in Figures 4 and 6. The longest earth fissure in Arizona, 8 miles in length, which also has a vertical displacement (Figure 4), crosses Interstate Highway 10 between bench marks Band c. The southeastern side of this fissure is now subsiding at the same rate as the northwestern side, 0.3 feet per year. An intensified- fissure pattern is developing north and south of Interstate Highway 10 within 2 miles of the existing long fissure. The subsiding a~eas of central Arizona are substantial as shown by Schumann 1974. In Pinal County within the lower Santa Cruz Basin from 1948 to 1967, an area of about 220 square miles subsided DDre than 0.5 feet and about 60 square miles of this area has subsided more than 3 feet. In the Stanfield-Maricopa area approximately 75 square miles has subsided more than 1 foot. Earth Fissures Earth fissures have existed in parts of Arizona for many years (Schumann-Poland 1969) and (Schumann 1974). The new mapping of these fissures confirms the fact that they

26 are continuing in or near areas of substantial subsidence (Figure 1). Three forms of intensification were noted during the mapping. First, fissures have occurred in new areas, second, fissures are developing an echelon with or parallel to older fissures, and third, older fissures have reopened. These forms of intensified fissuring are expected to continue unless stabilized ground-water levels are achieved. Conclusions The coincidence of areas of continued ground-water declines, continued subsidence, and increased earth fissuring support the view that there is a causal relationship begun by ground-water declines. These phenomena are having an adverse impact on habitation and agriculture. The full significance of ground-water withdrawal, subsidence, and earth fissuring is relatively unknown at this time. Much additional information, primarily costly field surveying, is needed to adequately define this potentially severe problem. The ground-water withdrawal, subsidence, and earth fissuring occurring in Arizona are broader in scope than existing agencies are able to address.

NOTICE OF EXERCISE OF SECTION 404 JURISDICTION OVER CERTAIN STREAMS AND LAKES

IN ARIZONA

The Federal Water Pollution Control Act amendments of 1972 (Public Law 92-500) requires a Corps of Engineers permit, under Section 404 of the Act, for the discharge of dredged or fill material into "navigable waters." Prior to 1972, Corps jurisdiction extended only over "navigable waters of the United States." The term "navigable waters" is much broader and has been administratively defined in Permits for Activities in Navigable Waters or Ocean Waters, para. (d)(2), Federal Register of 25 July 1975, P. 31324 (33 Code of Federal Regulations 209.120 (d)(2)). Jurisdiction will not be exercised over all "navigable waters" at once. It will proceed in three phases. Phase I covers all wetlands contiguous or adjacent to the traditional "navigable waters of the United States" and went into effect on the date of the above regulations, 25 July 1975. Phase II will include streams which are primary tributaries of "navigable waters of the United States," certain lakes, and all wetlands contiguous or adjacent to these streams and lakes. Jurisdiction under Phase II will be exercised 1 July 1976. Phase III will cover all tributaries of "navigable waters" and their contiguous or adjacent wetlands and will be effective on 1 July 1977.

All streams on the attached list and lakes, as defined below, and their contiguous or adjacent wetlands, are hereby included within Phase II. Jurisdiction shall be exercised upstream to the "headwaters" and laterally to the "ordinary high water mark."

The designation of these streams and lakes does not strictly limit the exercise of jurisdiction, but is published herein to identify, as a minimum, those waters which will come under the expanded Phase II jurisdiction. Jurisdiction may be exercised at any time, over any "navigable water", e.g., an intermittent stream, on a case-by-case basis whenever regulation is necessary for the protection 'of water quality. Separate Public Notices will be issued for streams and lakes in those portions of California, Utah, Arizona, Nevada, and New Mexico within the Los Angeles District.

36 Questions or inquiries regarding the exercise of jurisdiction over other waters or the limits of jurisdiction should be directed in writing to the Los Angeles District, ATI'N: Navigation Branch. Reference should pe made to the number and date of this.--,notice.

The following definitions have been excerpted from the above-mentioned regulations:

LAKES - Refers to natural bodies of water greater than 5 acres in surface area and all bodies of water (regardless of surface area) created by the impounding of the ~treams listed in the attached list.

Dredged Material - Material that is excavated or dredged from navigable waters. The term does not include material resulting from normal farming, silvaculture, and ranching activities, such as plowing, cultivating, seeding, and harvesting, for production of food, fiber, and forest products.

Discharge of Dredged Material - Refers to any addition of dredged material, in excess of -one cubic yard when used in a single or incidental operation, into navigable waters. The term includes, without limitation, the addition of dredged material to a specified disposal site located in navigable waters and the runoff or overflow from a contained land or water disposal area.

Fill Material - Refers to any pollutant used to create fill in the traditional sense of replacing an aquatic area with dry land or of changing the bottom elevation of a water body fcir any purpose. "Fill material" does not include the following: (i) Material resulting from normal farming, silvaculture, and ranching activities, such as plowing, cultivating, seeding, and harvesting, for the production of food, fiber, and forest products; (ii) Material placed for the purpose of maintenance, including emergency reconstruction of recently damaged parts of currently serviceable structures such as dikes, dams, levees, groins, riprap, breakwaters, causeways, and bridge abutments or approaches, and transportation structures.

Discharge of Fill Material~ The addition of fill material into navigable waters for the purpose of creating fastlands, elevations of land beneath navigable waters, or for impoundments of water. The term generally includes, without limitation, the following activities: placement of fill that is necessary to the construction of any structure in a navigable water; the building of any structure of impoundment requiring rock, sand, dirt,· or other pollutants for its construction; site-development fills for recreational, industrial, commercial, residential, and other uses; causeways or road fills; dams and dikes; artificial islands, property protection and/or reclamation devices such as riprap, groins, seawalls, breakwalls, and bulkheads and fills; beach nourishment; levees, sanitary landfills; fill

37 for structures such as sewage treatment facilities, .intake and outfall pipes associated with power plants, and subaqueous utility lines; and artificial reefs.

Wetlands - Refers to those lands and water areas that are periodically inundated and that are normally characterized by the prevalence of vegetation that requires saturated soil conditions for growth and reproduction. (Examples include shallows, swamps, marshes, and mudflats.)

Primary Tributaries - Refers to the main stems of tributaries directly connecting to navigable waters of the United States up to their headwaters and does not include any additional tributaries extending off of the main stems of these tributaries.

Headwaters - The point on the stream above which the flow is noI'!Ilally less than 5 cubic feet per second provided, however, the volume of flow, point and nonpoint source discharge characteristics of the watershed, and other factors that may impact on the water quality of waters of the United States will be considered in determining this upstream limit.

Ordinary High Water ~..ark - With respect to inland fresh water, this means the line on the shore established by analysis of all daily high waters. It is establi'shed as that· point on the shore that is inundated 25% of th~ time and is derived by a flow-duration curve for the particular water body t hat is based on avai lable water stage data. It may also be estimated by erosion or easily recognized characteristics such as shelving, change in the character of the soil, destruction of terrestrial vegetation or its inability to grow, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding .. area.

Maps showing these water bodies are available for viewing in the Navigation Branch, Los Angeles District office.

Reference should be made to the number and date of this notice.

The following definitions have been excerpted from the above-mentioned regulations:

LAKES - Refers to natural bodies of water greater than 5 acres in surface area and all bodies of water (regardless of surface area) created by the impounding of the streams listed in the attached list.

Discharge of Dredged Material - Refers to any addition of dredged material, in excess of 1 cubic yard when used in a single or incidental operation, into navigable waters. The term inclu4es, without limitation, the addition of dredged material to a specified disposal site located in navigable waters and the runoff or overflow from a contained land or water disposal area.

Fill Material - Refers to any pollutant used to create fill in the tradi tional sense of replacing an aquatic area with dry land or of changing the bottom elevation of a water body for any purpose. "Fill material" does not include the following: (i) Material resulting from normal farming, silvaculture, and ranching activities, such as plowing, cultivating, seeding, and harvesting, for the production of food, fiber, and forest products; (ii) Material placed for the purpose of maintenance, including emergency reconstruction of recently damaged parts of currently serviceable structures such as dikes, dams, levees, groins, riprap, breakwaters, causeways, and bridge abutments or approaches, and transportation struc tures.

Discharge of Fill Material - The addition of fill material into navigable waters for the purpose of creating fastlands, elevations of land beneath navigable waters, or for impoundments of water. The term generally includes, without limitation, the following activities: placement of fill that is necessary to the construction of any structure in a navigable water; the building of any structure of impoundment requiring rock, sand, dirt, or other pollutants for its construction; site-development fills for recreational, industrial, co1m11ercial, residential, and other uses; causeways or road fills; dams and dikes; ar.tif icial islands, property protection and/or reclamation devices such as ~iprap, groins, seawalls, breakwalls, and bulkheads and'fills; beach nourishment; levees, sanitary

41 Public Notice No. 404-Phase III 15 June 1977 landfills; fill for structures such as sewage treatment facilities, intake and outfall pipes associated with power plants, and subaqueous utility lines; and artificial reefs.

Wetlands - Refers to those lands and water areas that are periodically inundated and that are normally characterized by the prevalence of vegeta tion that requires saturated soil conditions for growth and reproduction. (Examples include shallows, swamps, marshes, and mudflats.)

Primary Tributaries - Refers to the main stems of tributaries directly connecting to navigable waters of the United States up to their head waters and does not include any additional tributaries extending off of the main stems of these tributaries.

Headwaters - The point on the stream above which the flow is normally less than 5 cubic feet per second provided, however, the volume of flow, point and nonpoint source discharge characteristics of the watershed, and other factors that may impact on the water quality of waters of the United States will be considered in determining this upstream limit.

Ordinary High Water Mark - With respect to inl.and fresh water, this ~eans the line on the shore established by analysis of all daily high waters. It is establi_shed as that point on the shore that is inundated 25% of the time and is derived by a flow-duration curve for the particular water body that is based on available water stage data. It may also be estimated by erosion or easily recognized characterisHcs such as shelving, c-hange in the character of the soil, destruction of terrestrial vegetation or its inability to grow, the presence of littc;r and debris, or other appropriate means that consider the characteristics of the surrounding area.

Maps showing these water bodies are available for viewing in the Navigation Branch, Los Angeles District Office.

Please call our Navigation Branch, (213) 688-5606, if you have any questions regarding this notice or permit procedures.
