It also includes policy statements which have ' been adopted by the town council with respect to the town's future growth. The plan also attempts to resolve many un— ' answered questions about the character and nature of future development as well as who should pay for it. Generally speaking, a comprehensive plan deals primarily P ' with physical development. But, it also sets forth a con— sistent set of goals and objectives accompanied by policies and procedures for achieving the goals, all of which are ' accomplished through a combination of public and private actions. A comprehensive plan has three essential characteristics: 1. It is LONG — RANGE. It covers an indefinite time span. 2. It is GENERAL. It focuses attention on goals and i objectives such as public health, safety and economic well being rather than on _project plans such as plans for buildings. 1 3. It is COMPREHENSIVE. It deals with the entire town and surrounding area. A comprehensive plan is comprised of four basic elements and three implementing devices or programs as follows: Basic Elements: 1. A transportation plan ' 2. A community facilities plan 3. A .land use plan 4. A housing Plan 1 1 1 Implementing Devices Or Programs: 1 1. An Advocacy Program 2. A Development Code 1 3. A Multi —Year. Improvement Program Integration No single element can qualify as a comprehensive plan. In fact, not until all of the four elements have been inte— grated, adjusted, and made to harmonize with each other does 1 the plan become comprehensive. Most of the mistakes that cities and towns make in their physical development stem 1 from a lack of integration. The lack of integration that can be observed in nearly all cities is where some streets turn out to be too narrow where they should be wider, or where the streets turn out to be 1 excessively wide where they should be narrower. The integra— tion of land use and housing plans with transportation and 1 community facilities plans helps to avoid such mistakes. Use of the Comprehensive Plan 1 A comprehensive plan is used primarily by administrative and elected officials, but it is also of value to developers and other property owners and citizens. A comprehensive plan should be looked upon as a process, rather than as a one time project because the plan covers a long period of time. More— 1 over, conditions and needs constantly change as well as ad— ministrators and officials. Not only that, but, development II j takes place on a house by house basis and by many individuals and agencies, not the least of which is the town itself. 1 The plan must also be updated from time to time in order for the plan to remain a useful instrument. Hopefully, this comprehensive plan document will not become an end in itself, but will fulfill its true role of becoming a tool with which 1 2 1 1 the present and future residents of Marana can build a better community than could be built without such a plan. After the plan and implementing devices have been adopted ' they should be placed in a location where all interested parties may have frequent reference to them. 1 Scope The area covered in Marana's Comprehensive Plan includes the ' incorporated area and adjacent territory, including much of ' the northern part of Avra Valley. While the planning and programming of improvements will be confined to the territory ' within the Town boundaries, it will be necessary to have to take into account development which exists and which is likely to occur in the surrounding area. Implementation Implementation of the plan will involve cooperation and coor— dination with the Cortaro Water Users Association, Marana School District and various other special purpose districts; with the county assessor and with other county, regional, and federal agencies. In the final analysis, the success of the plan will ' depend largely upon the degree of cooperation that will take place between the foregoing agencies, the administrative of— ficials and the citizens. As the Town Council and Administrative officials begin to implement the plan, it will become increasingly apparent to them that it is not the plan that will be at fault nearly as much as the oversights that are made in its implementation. 1 3 1 1 THE COMPREHENSIVE PLAN ' Goals It is a fact of nature that we unconsciously put in motion forces which bring about the image we have of ourselves. If our self -image is vague and ill defined, we tend to vacil late. On the other hand, if our self -image is clear and con- cise, we tend to be more direct and forthright in our actions. In the same manner, if the community's self -image is vague and ill defined, the people tend to vacillate in their efforts ' to achieve their goals; but if their goals are clear and con- cise, they tend to accomplish them in a much more expeditious ' manner. To be of most worth, community goals must be expressed in clearly defined and understandable terms. A community with a set of generally accepted goals possesses an achieving force that is almost irresistible when accompanied by a town council that desires to achieve the goals. 1 Daniel Burnham said, as he launched the Chicago plan that 1 helped to change Chicago from a small community to a giant metropolis, "Make no little plans, they have no magic to stir men's blood and probably themselves will not be realized. Make big plans. Aim high in hope and work remembering that a noble, logical diagram once recorded will never die but long after we are 1 gone will be a living force, asserting itself with ever growing insistence. ' Remember that our sons and grandsons are going to do things that would stagger us. Let your watchword be order and your beacon beauty." 4 1 1 A community is great not because of its size, but because of its spirit. Good homes, attractive surroundings and congen- ial people emanate from a spirit of achievement. 1 What should the goals be for Marana? This question has been answered by a Planning Advisory Council. Approximately 20 citizens were appointed by the Mayor to serve on an advisory ' council. Their task was to formulate a statement of goals and to give counsel and advice to guide the preparation of the comprehensive plan. Following is a summary of the goals which were recommended: 1 1. To improve living conditions within the town by: 1 a. Promoting environmental sanitation, along with public health and safety. b. Eliminating or reducing as many obstacles as possible which prevent families from having a decent, safe and sanitary home in which to live. c. Encouraging developers to construct owner occup- ied planned unit developments that provide for well maintained recreational facilities within the developments rather than conventional sub- divisions that have no such facilities. 2. To strengthen the economy of the community by: a. Encouraging industrial development that will pro- vide jobs in a manner that will harmonize with ' the land use plan. b. Providing accommodations for tourists and bus - iness people. c. Increasing the water supply which will allow 1 more land to be cultivated. d. Discouraging the fractionalization of ' productive agricultural land for urban purposes as long as non - productive parcels of land are al- ready available for such purposes. ' e. Encouraging residential, commercial and industrial 1 5 i development to take place in a concentrated man— ner, rather than in a scattered manner that re— sults in vacant and unused parcels of land. 1 f. Preparing and adopting a multi —year improvement program for the town which will show needed capital improvements in order of priority. g. Adopting street and water and sewer line exten— sion policies that will cause the beneficiaries thereof to assume the costs in so far as possible rather than to saddle the costs onto the tax— payers. h. Requiring subdividers and builders to construct ' curbs and gutters within their subdivisions and by requiring them to construct connecting hard surfaced streets and sewer lines at their expense, rather than to saddle these costs on the tax— payers. 3. To improve physical facilities by: ' a. Adopting a system of local, collector, and art— erial streets that will harmonize with the land ' use and housing plans. b. Requiring utilities to be installed before paving ' streets, in order to prevent excavations after the hard surfacing has been constructed. c. Adopting a system of bicycle paths and horse trails in connection with major streets. d. Encouraging home owners to landscape their home grounds, to improve or remove dilapidated build— ings, to remove weeds and trash from vacant lots, 1 to close and obliterate unused irrigation ditches, to construct sidewalks where needed, to provide , adequate offstreet parking in connection with all new buildings, to adopt and enforce codes, ordinances, and improvement programs designed to enhance the overall quality of the environment. e. Planting street trees wherever abutting property 6 1 II owners are willing to maintain them. f. Providing underground water recharge basins and 1 check dams along the flood channel of the Santa Cruz River and by connecting the basins with a 1 linear park system. I 4. To improve civic responsibility by: a. Encouraging more citizen participation — youth and adult — in local government and community 1 affairs. b. Generating a spirit of appreciation and congen- 1 iality among all of the citizens of the community. c. Inviting and encouraging minority, ethnic and I social groups and individuals to participate in community and civic affairs. d. Developing an attractive civic center in keeping with the needs and the wishes of the people. e. Constructing a fire station. III f. Constructing an entrance monument for the town. g. Appointing and maintaining a town planning com- 1 mission to facilitate the implementation of the comprehensive plan and to update it as needed. I h. Appointing an industrial development commission. i. Appointing and maintaining a shade tree and I beautification commission. j. Appointing a transportation commission. k. Appointing and maintaining a parks and recreation II commission and such other commissions and boards as are necessary and appropriate to study con- 1 ditions and advise the Town Council. 1 1 1 1 7 1 1 URBAN FORM 1 One of the first tasks in developing a comprehensive plan for Marana should be to determine the type of "urban form" or 1 development pattern that best suits the community. The reason the selection of a particular "urban form" is so I important at the outset is that all of the other elements of the plan are geared to the selected type of "urban form." 1 The forms that should be considered are: 1. The scattered form 2. The core form 1 3. The linear form 4. The Multi —core form Following are diagrams which graphically represent the various types of forms; ...4 med ... . , lib • ilp ., . i to ...., s i t L 3 . . cr k g ,... -: vo .1. "14::......

'''t • t • ....... viii .1. 40* MI , s� •� II LINEAR FORM • MULTI —CORE FORM 1 There are advantages and disadvantages for each type of ur— ban form: II 1. The scattered type of urban form is very expensive to maintain because it requires extra long utility lines, streets and other improvements in relation to the amount of development. Development of this type also causes numerous 8 ' 1 1 weed patches and vacant lots and parcels of land. It also becomes necessary to install small water lines and narrow surfacing on the streets with few, if any, sidewalks. Event— ually, it becomes necessary to increase the property taxes to provide the funds with which to install adequate streets and services as further development takes place. On the other hand, few, if any, regulations are needed to bring it about. It develops naturally, in fact, the town 1 will develop in this manner if nothing is done to prevent it. This type of development eventually results in rural slums. 2. The central core type of urban form is by far the most effieent with respect to the cost of constructing and maintaining public facilities. The streets and utilities ' are short in relation to the amount of development. Conse— quently, more and better quality public facilities can be had at much less cost per dwelling unit. There are not as many vacant lots and unused parcels of land nor is there a need to tax the people to obtain revenues with which to enlarge streets, water lines, etc. In other words, demands on the taxpayers are much less and distance between homes and the business districts, schools and industry is usually much less than in other types of "urban forms." On the other hand, this type of "urban form" requires the most conscious effort, including the insistence that develop— ers pay for all improvements in their subdivisions, or plan— ned unit developments. 1 3. The linear type of "urban form" is somewhat incon— venient; distances between various types of land uses are long and the tendency to mix incompatible uses is great. There is also a tendency for development to string out along principal highways wherever action is not taken to prevent it. Especially is action required which specifies that developers 1 9 1 must install both on -site and off -site improvements in sub- divisions otherwise development will take place in a scat- tered manner and the taxpayers will eventually be forced to construct and pay for the improvements. The linear form, however, may serve as a transitional pat- tern while the core or multi -core forms are evolving from an original scattered form. 1 4. The multi -core type of "urban form" has some of the characteristics of both the linear type and the central core type. It also has some advantages and disadvantages. It 1 cost more to maintain the multi -core type than the central core type, but not as much as the scattered or linear type. The multi -core type requires less deliberate effort than the central -core type, but more than the scattered or linear type. A review of the physical characteristics of Marana indicates that the multi -core type of "urban form" would best suit the town. It is nearly as efficient in terms of the construction and maintenance of utilities and other municipal services, ' and it is the way in which development has already taken place. Moreover, it would be relatively easy to take the necessary steps to bring it about.* It, rather than the sin- gle core form would also prevent excessive control over the 1 community by one or a few major landowners. If fundamental economic forces are allowed to operate, it will provide the greatest effieiency combined with the greatest degree of in- 1 dividual freedom. The most difficulty involved in bringing the multi -core type of urban form about, yet most effective, would be for the Town Council to require prospective home builders to construct * People resent regulations and high taxes. Consequently, developers will be required to construct improvements at their expense because improvements which are not construct- ed by developers must eventually be constructed and paid for out of tax funds. 10 1 1 all water and sewer mains and hard surfaced streets to town standards at their expense as a condition of approval of their II developments, especially those requiring new streets. II Where this is done, the vacant lots along streets already served by water and sewer lines would become more desirable as building sites, mainly because of the expense of extend- I ing the service to the more distant lots, or the expense of constructing entirely new streets. II All of the elements of the plan as well as all of the imple- menting devices and programs have been prepared under the assumption that the multi -core type of urban form, or urban II pattern is the most desirable type of form for the Town of Marana. I Land Use Projections 1 As indicated above, Marana contains a total of 18,300 acres of land, only 810 of which have been developed for urban II purposes. Assuming that the Town has a population of 1,600 people who are domiciled in approximately 400 dwelling units, 1 it can be seen that the average amount of land used for urban purposes is approximately 2.0 acres per dwelling unit. This is an unusually large amount of land compared to most com- 1 munities. II Why so much land has been devoted to urban purposes can be attributed primarily to the length of streets in relation to II the number of dwelling units. II In all likelihood the relationship among the various uses of land will trend toward the normal as population increases. I Thus, the percentage of land devoted to residential and com- mercial uses can be expected to increase while the percent- age of land devoted to streets will decrease. II 1 11 1 Also, as population increases in a community, so does the 1 number of people or density per acre of developed land. While density in Marana is currently only 2.0 people per 1 acre of developed land, it can be expected that the density will be approximately 4.0 people per acre when population reaches 5,000 and approximately 6.0 people per acre when the population reaches 10,000. This occurs because of the re— latively higher percentage of multiple family dwellings that 1 are usually constructed in a community as population increases. As shown in the paragraph entitle Land Resources, there is approximately twice as much land or about 200 acres more land devoted to streets in Marana than is characteristic of normal cities and towns having a population of 1,600 people. By sub— tracting 200 acres from the total amount of developed land of 810 acres, it can be seen that the land which would be used in a normal community would be 610 acres or approximately 2.6 people per acre, except that the overall density will likely increase as population increases. 1 Thus, at a density of population of 4.0 persons per acre a population of 5,000 people could be expected to use approxi— mately 1,250 acres of land for urban purposes, while a pop— ulation of 10,000 could be expected to use approximately 1,670 acres of developed land.* 1 In any event, the total number of acres of land that will likely be devoted to urban purposes will be comparatively small in comparison to the total area contained within the Town's boundaries. However, the manner in which the growth takes place will make a great difference in the cost of sup— plying services as well as in the amount of damage in the agricultural economy. , If, most of the added dwellings, commercial buildings, schools, 1 Note— See "Land Use In American Cities" by Bartholomew, 1955. 1 12 1 1 churches, parks and streets are clustered in the areas shown on the land use plan, it may not be necessary to impose much of a property tax in order to provide necessary services. However, it will be necessary to impose a substantial pro— perty tax if the scattered type of urban form develops. 1 1 1 1 1 1 1 1 1 r 1 1 1 1 1 13 1 A ASSU1PTIONS The recommendations contained in this Comprehensive Plan must, of necessity, be based on certain assumptions as well as the results of detailed studies of the area. These as— sumptions have been set forth below: It has been assumed that: 1. Marana will continue to grow primarily in response to (a) further industrial activity, (b) . a continuation of ' agricultural activity, (c) the development of tourism and other leisure time activities, and (d) desire to live in a semi —rural area. 2. The town council will adopt this plan and will main— tain a viable implementation program from one administration to the next. ' 3. The town council will avail itself of the services , of professional administrators who will demonstrate imagina— tion and initiative in their efforts to help the council achieve the goals set forth in this plan or as they may be expanded to reflect the changing desires of the people. 4. The people will take an increasingly more active interest in civic affairs and will support the council's 1 efforts to provide an increasingly better place in which to live. ' 5. No adverse development will occur in the area which , will bring about serious reversals of past trends or of the goals set forth herein. 14 r TRANSPORTATION PLAN The transportation element concerns all facilities within the area which are utilized for the movement of goods and people. In Marana these include highways, streets, alleys, airports, canals, horse trails and bicycle paths. Highways, Streets and Alleys r Highways and streets exert a major influence upon a com- munity's development. In a manner of speaking, the street system is the bloodstream of the community. It is also the ' framework of the town and is the major controlling factor in the location of buildings, utilities, and drainage. Accord- ' ingly, a well - designed and adequate street system which is r properly coordinated with existing and projected uses of land in the surrounding area, is essential to the proper and effic- ient development of the community. ' A town's street system serves five major functions: t It provides a means of access to property. 2. It facilitates the movement of goods and people r into, through and within the town. r 3. It serves as a channel for the location of utility and surface drainage systems. 4. It acts as open space for light and air to adjoining properties and separates buildings so as to prevent conflag- rations from occurring. ' 5. It facilitates the delineation of the town into neighborhoods and gives identity and meaning to the structure of the town. r 15 1 Average daily traffic over most of the community's streets t may be considered as light. Traffic volumes along the Town's major arteries (federal, state and local) have been shown on State DOT maps, It can be seen from the maps that Interstate 10 carried 16,000 average daily trips, .that San Dario Road between the interchange and Grier Road carried 2,400 ADT while other roads carried a lesser amount of traffic in 1978 as shown on the maps. , Street Classification 1 The street system in Marana consists of three general types of streets: arterials, collectors, and residential or minor streets. II 1. Arterial Streets. The primary function of arterial streets is to facilitate the movement of relatively large 1 volumes of traffic through the town, or between the town and other communities. The minor function of arterial streets ' is to provide access to abutting property. Avra Valley Road, San Dario Road south of the Avr a Valley .Air ort P ,, Moore Road, Trico — Marana Road,and Sanders Road along with the freeway have been classified as arterial streets. 2, Collector Streets. The primary function of collector II streets is to serve as a connecting street between arterial streets and traffic generators and to facilitate the move— 1 ment of traffic between neighborhoods. However, another important function of collector streets is to provide access to abutting properties. While San Dario Road between I -10 and Moore Road is presently classified as a collector street, Grier, Postvale, Luckett, Avra, Hardin, Old Siverbell, Barnett, ' Twin Peals, and Kirby — Huges Road should also be classified as collector streets in anticipation of future development. 1 As population increases and other urban growth occurs, the frontage road along the east side of the freeway should also 1 16 1 1 be classified as a collector street. Steps should then be taken to preserve the rights —of —way, so that the streets can be constructed without excessive right —of —way cost, in the event that it eventually becomes necessary to widen the streets. It is a mistake to assume that collector streets that are 1 narrower than the indicated cross— sections are adequate just because they are wide enough to handle the present volume 1 of traffic. The cost of acquiring needed right —of —way and widening roads which have been lined with dwellings becomes ' prohibitive. 3. Minor Residential Streets. The primary function of 1 minor residential streets is to provide a means of access to abutting properties. Minor street systems should be de- 1 signed for relatively low speeds so as to discourage their use for through travel, especially through the interior of neighborhoods. Minor streets within neighborhoods should not ' be as wide as collector or arterial streets. Minor streets should always be constructed narrower than collector or 1 arterial streets as a matter of safety, but not so narrow as to create congestion. r Standards Recommended cross— sections for each class of street within Marana are shown on the following maps. For new streets 1 these should conform to the width of streets called for in the development code. In this manner, the streets which the ' municipalities may build and the streets which subdividers and developers may build will be consistent. Where the width of the streets have already been established, such as in the platted part of the Town, it may be necessary to adopt a modified cross — section. The cross — section which should be applied, has been shown 1 1 17 1 for each type of street. This should be used as a guide 1 to abutting property owners in the development of their property, as well as a guide to the town and the county in the construction of various streets. Whenever curbs and gutters are constructed and whenever streets are widen— ed, it should become standard practice to do the work in conformance with adopted cross— sections. 1 The Major Street Plan The major street plan for Marana covers arterial and col— lector streets and consists of two parts: 1. A map showing the location of major streets (both existing and proposed), within and around the community , shown on page 20. 2. Recommended right —of —way widths and cross — section ' standards for each of the two classes of major street and for minor or residential streets shown on page 21 to 30, , While the existing major street system is generally adequate , to accommodate current and foreseeable traffic volumes within the Town, the system will eventually become inadequate as dev— elopment takes place unless the plan is adheared to. All street improvements should be required in all future residen— tial subdivisions as a condition of approval thereof, otherwise, 1 the Town will probably be forced by public demand to levy a tax on the property with which to improve the streets. II The map on page 20 also shows all of the streets that the Town should maintain. There are streets that are substandard as to width. Those have not been shown. Generally speaking, the II Town should refrain from grading or paving them until the abut— ting property owners have dedicated the land needed on which to construct streets of proper width. ' III 18 1 ' Airport The airport, located near the intersection of San Dario and Avra Valley Road, while not within the Town limits, is with- 1 in the community. The airport is classified by the FAA as a local service facility. It has two paved runways with lengths of approximately 2,500 each, The facility is used ' by private owners and several other agencies. Facilities at the airport are adequate for present usage, but additional facilities will likely be needed in the future, in the event that traffic from place of residence to work and back develops significantly or in the event that the airport becomes a base for fly —in industries. Horse Trails and Bicycle Paths Horse trails and bicycle paths should be constructed along— side secondary and arterial streets as shown on the typical cross—sections. It may also be appropriate to provide for a bridle path along sections of the Santa Cruz River, in the future, in the event that the area is developed as a linear park and floodway.

While most all communities have need for certain types of community facilities such as water and sewer facilities, each community has its own particular needs. In Marana these should include: 1. Water supply and distribution facilities 1 2. Sewerage facilities and sewage disposal 3. Solid waste collection and disposal 4. Storm drainage and flood protection 5. Educational facilties 1 6. Recreational facilities 7. Municipal Offices and shops 8. Entrance Monument 1 9. Library 10. Fire protection 1 11. Health Care facilities 1 Water Supply and Distribution Facilities. It should be the objective of the Town Council to make sure 1 that the supply of water is adequate for users within the Town limits at the lowest feasible rate. Where water is expensive for the homeowners they refrain from using it. Where it is inexpensive homeowners tend to use it profusely, $ not only for both culinary use, but also for lawn watering, gardens, livestock and other outside uses. Where water is not metered or measured the tendency is to waste it. 1 While it makes little or no difference whether the water supply is owned and distributed by the town or by another agency, it is important that the agency in control of the 29 11 water supply and distribution system maintain certain pol— icies which are consistent with the goals and policies of the Town. In view of the fact, that most domestic water is 1 furnished by water companies, the following policies should be adopted by each company. ' 1. Cost of expansions and hook —ups for domestic water should be made at the expense of the developers, or those who request the service. Also, the size and capacity of the expansions should be made to comply with traditional stand— 1 ards for fire protection as well as for domestic use. 1 2. All expansions in the domestic system as well as all hook —ups to the system should be made in a manner that 1 will be consistent with the land use plan. No expansion or hook —up should be made to non —farm dwellings or residential subdivisions except in the areas designated for residential use. 1 3. The companies should require developers or the peo— ple who request the service to install water meters wherever 1 water is removed from the system. 4. Cost of the water should be made available at the lowest possible cost consistent with good management. ' It will no doubt be necessary for water companies to replace small water mains with larger mains at their expense, as new 1 hook —ups are added to already existing mains. All new ex— tensions to the system should be made at the petitioners expense and not the water company's expense. 5. All water mains that are installed in public streets should be not less than six (6 ") inches in diameter so that the flow of water will be sufficient to meet minimum fire flow standards of 500 gallons per minute. Where a large num— 30 1 ber of dwellings will likely be supplied through a single source, some of the water mains may have to be larger than 6" in diameter in order to supply peak demand. 1 Sewerage Facilities and Sewage Disposal Domestic sewage disposal in.iarana'is accomplish- ed for the most part by the use of individual septic tanks and drain fields except for a sewerage system that collects domestic wastes from some of the dwellings in the area lying east of San Dario Road and north of Grier Road. A 6" outfall 1 line extends from the collection system and terminates approx— imately 5 miles west in a 2.5 acre containment lagoon. Sewerage S Plan g P Because of the favorable percolation qualities of the soil in Marana, individual septic tanks and drain fields should be adequate for farm dwellings. However, in the case of sub— divisions, a policy should be adopted by the Town Council re— quiring the size of any sewer main (except service lines to individual buildings) to be not less than eight inches (8 ") in diameter.. The major reason for this is to avoid the nec— essity of ever having to replace or duplicate small sewer lines along streets as new hook—ups are made into the main— I lines. An eight inch (8 ") line will carry almost twice the amount of sewage for a very small increase in overall cost of installation. Whenever a.sewer becomes overloaded, it becomes necessary to construct a parallel sewer line because it is impractical to connect existing service lines to new sewer mains. Where this ' is done, the community must maintain two sewer lines on the same street which become difficult to keep separate and in ' good repair. Moreover, the sewer mains must be installed at different elevations so that they will not interfere with each other. 31 11 Marana's lagoon treatment facility works quite well. How— t ever, some additional work may be required on the facility as the Town grows in order to maintain the quality of the 1 effluent within quality control standards. The ponds may either have to be enlarged so as to handle more sewage as the population increases or else it may be necessary to change the manner of treatment in order to make sure that the ef— fluent from the treatment facility will comply with State standards. The lagoon or pond at Marana, is located in the flood plain of the Santa Cruz River and will require additional flood 1 protection work to be performed in the area above the ponds in order to prevent flood water from washing out the ponds. Evidence from floods that occurred in 1978 — 79 along the Santa Cruz River should be sufficient proof for the need for such flood protection.. Following is a statement which appears in the 208 Area Wide Wastewater Management Plan for Pima County. 1 "Population projections indicate that the existing 1 facility pond will eventually be overloaded. While overloading has not occurred as yet, a satisfactory treatment system can be maintained by completion of the 4 —acre ponds directly adjacent to the existing 2.5 —acre ponds." The report then indicates that there are flooding problems at the site and recommends that a planning study be conducted in the immediate future, particularly before more hook —ups 1 have been added to the system. The current rural character of the g eneral area and the re— moteness of the site are favorable for pond systems. However, it can be expected that the ponds will become objectionable to home owners in the event that subdivisions or other housing 32 ' projects are constructed in the immediate vicinity of the ponds. Mechanical disposal facilities such as the system ' used by Tucson will involve monthly operating costs, while containment lagoons or ponds are almost cost free after they have been constructed. It is recommended that the planning effort consider consoli— dation of all point sources in the vicinity of Marana, i.e., Marana school, etc., and that the construction of dwellings be discouraged in the vicinity of the ponds. Meanwhile an additional containment pond should be constructed as new hook —ups are added to the system and both ponds should be - protected from flood waters. Eventually, the six (6) inch diameter outfall line leading to the ponds may also have to be enlarged. The effluent should be reused and returned to underground acglzifers wherever feasible. Other sewage lagoons should be constructed in the locations as indicated on the public facilities plan as they become necessary. See page 20. Solid Waste Collection and Disposal 11 Surveys that have been taken over the country indicate that families generate approximately five pounds of waste mater— ial per capita per day. Consequently, efficient and conven— ient solid waste collection and disposal contributes to the 1 environmental health and general housekeeping of the community. Currently, the waste disposal site for Marana is located along the Tangerine Road in an abandoned gravel pit. The County has maintained the facility for the use of the people in ' Marana as well as for many other people in the surrounding area. Pima County uses the cut and cover method of solid waste dis— posal. However, paper and other types of debris can be seen around the facility which has not been covered. Consequently, there has been some dissatisfaction with the operation of the facility in that area. Costs of adequate maintenance of a solid waste disposal fac— 1 33 11 ility has always been a major factor in the operation of ' such a facility. It has been particularly difficult for small communities to purchase equipment and operate it be— 1 cause of the high cost of the equipment and operators time compared to the volume of waste material handled. Unless an operator is in attendance from early morning until after sundown 6 days a week, including holidays, residents often dump their waste material at the site or along roads leading to the site only to be left for the operator to pick it up and dispose of it. t Because of the difficulty and expense of maintaining disposal 1 sites both large and small communities have adopted man— datory waste disposal programs wherein the owners of all ' dwellings and business must pay a monthly fee to have their solid wastes disposed of whether or not they make use of the service. Characteristic fees range from $5.00 to $10.00 per month depending upon the method of disposal and the length of haul from origin to destination. To ignore the need for a garbage disposal facility usually result in a litter strewn community. 1 It may be that the County would consider moving the facility to a location on the east side of the freeway where it would be less obvious to the traveling public and to the residents. ' Before abandoning the present cooperative operation with the County however, the Town Council should investigate the cost , of alternative disposal methods or locations. M Storm Drainage and Flood Protection The natural topography and the characteristics of the soil and drainage pattern of Maranahave made it possible to pro— vide adequate surface drainage without extra cost for special storm drainage facilities. Moreover, future development can 34 1 1 be handled so that storm water will never present much of a problem to the Town if proper precautions are taken in the development of streets to facilitate infiltration of water into the ground. .In order to accomplish this, it will be necessary to direct the runoff along many channels on its way to the river. • L, - with By using care in the construction of street water 1 the frequent use of rock filled sumps, most of can be made to percolate into the ground or else It can e be r un in a north westerly direction so that storm water i ' the river's flood plain in several places. The water can there — by be prevented from growing into desi;ruetive streams. To make this feasible, the Town should have a contour map prepared and request its engineer to work out an overall drainage system so that each curb and gutter project can be ' made to conform to the plan. Facilities can then be con— structed as development takes place that grill handle most 1 floods without much additional cost. It will become very expensive for the Town to correct improper installations 1 after more of the streets have been lined with curbs and gutters if ground water recharge and drainage are neglected° The greatest potential damage to the Town from floods, lies along the banks of the Santa Cruz River and in the bed of the dry wash, north of the junior high school. The river and wash are both curses and blessings. Floods have the capacity to do a great deal of damage to life and property but they are also the major source that feeds the underground ' water supply. It has been estimated that several thousand acre feet of water flow into the Santa Cruz Flats without being used very benefi— cially. It has also been estimated that all water that enters 1 35 into underground water acquifers is potentially usable at ' least twice before being lost to evaporation. Any effective program that will introduce more flood water into subterranean water acquifers would be beneficial in that it would allow more acres of land to be cultivated. It I/ is recommended that the Town Council work with the Cortaro Water Users Association and other interested agencies along the entire length of the Santa Cruz River in an effort to recharge underground water acquifers and to do so in a man- 1 ner that will reduce the amount of flood water during flood time. The retention basin located at the crossing of the 1 Trico - Marana Road near the west boundary of the Town is an example of such a basin. Provisions should also be adopted in the Town's Zoning Ord- inance which will prevent the construction of buildings in the flood plain of the river. Otherwise, washed out build- ings may create a dam during a flood which may divert the ' water along an entirely different course. Educational Facilities School facilities for the people of Marana are located at three sites. If, and when, the number of students increases to a point where another school site is needed, the standards adopted by the National Council on School House Construction should be followed. Minimum site sizes are as follows: ' 1. For elementary schools -- a minimum site of ten acres, plus one additional acre for each 100 students of predicted ultimate enrollment. ' 2. For junior high schools -- a minimum of 20 acres, plus one additional acre for each 100 students of predicted ultimate enrollment. 36 3. For senior high schools -- a minimum of 30 acres, plus one additional acre for each 100 students of predicted ultimate enrollment. Elementary schools should be located in the center of res— t idential neighborhoods so that as many students will live within walking distance of the school as possible. The ' school site itself should be located away from busy thorough— fares and away from commercial and industrial activities. 1 Secondary schools, on the other hand, become traffic gener— ators in and of themselves. Many of the older students drive automobiles, and for this reason secondary schools should be located adjacent to major streets where convenient access can be had to and from all parts of the district. Even so, the site should be far enough away from noise and traffic hazards and from commercial and industrial activities so that good teaching situations, can be maintained at all times. Soil on which school sites are located should be suitable for the planting of trees, grass, and shrubs. The soil should also be free of rocks, while the sub —soil should provide an adequate base for foundations. Also, the sites should be well drained.* Present school sites do not always ' comply with the above recommended standards as to either size or location, but they exist in Marana and will pro— ' bably remain as is. Authority for the school districts and municipalities to cooperate in providing parks and outdoor recreation fac— ilities can be found in the joint powers act as adopted sev— eral years ago by the legislature. In the event that it becomes necessary to acquire a new site for an elementary Source: National Council on School House Construction, Research and Publications Committee, NCSC Guide, ' East Lansing, Michigan. 1 57 1 school, coordination and needs of both the Town and the 1 school district should be given prime consideration in the selection and development of the sites. 1 To be most compatible with the comprehensive plan, a site immediately north of the Honea Heights Subdivision should be selected along with one or more alternate sites and arrangements should be made with the landowners to preserve 1 the site for school purposes. Thus, the land can be retain— ed in productive use until it is needed for school purposes. 1 If the population increases, significantly, it will likely be necessary to expand the Jr. high school facilities or to build an elementary school at the above location and con— vert one of the elementary schools into a middle school. The possibility of this occurring should be considered now and appropriate action taken as outlined heretofore in this 1 document. (See public facilities plan on page 20) Recreational Facilities Facilities for recreation in urban communities should con— sist of a variety of sites, buildings, equipment and E:truc- tures provided by private businesses as well as by schools and local government. These facilities are used by young children, school age youth, adults and visitors. 1 Existing recreation facilities for ttie people who live in Marana 1 are contained in a 30 acre park next to tae Jr. high school. A sports field is also located at the Jr. high school site. The 1 Sr. high school is located south of the town boundaries near San Dario Road and also contains athletic facilities. 1 Indoor recreation facilities should be primarily located in the schools so that it will not be necessary for the Town 1 to duplicate such facilities in separate locations as is 1 .38 1. 1 I currently being done in many other areas. Where appropriate the Town should acquire park sites adjacent toschools and II the recreation program should be handled jointly. II Guidelines. Standard guidelines suggest approximately ten acres of park and playground space per 1,000 population and I that 30 to 40 per cent of the total area should be used for active play. The remaining part that is not covered by buildings, driveways, walks, etc., should be devoted to I passive recreation consisting of open lawn areas, benches, shrubs and trees. Standard guidelines also suggest that 1 the size of the community, density and nature of the surround— ing environment should have an influence on the amount of II recreation facilities provided. Since a park has already been developed by the County, south of the Jr. high school, II it is unlikely that additional land will be . needed, except land which should be acquired adjacent to an ,elementary , school across the Moore Road north of the Honea Heights Sub— , division. II Municipal Building II Municipal buildings serve two principal functions: They house town offices and serve as an image maker or focal II point of community pride. In order to serve these functions best, a town building should be located in the central part of the community. The present location of the Town Hall is II consistent with this principle. II The importance of image is becoming increasingly significant. As additional development takes place in the Honea Heights I neighborhood, it may be necessary to increase the floor space in the present Town Hall. In view of the fact that Sanders II Road has been designated as an arterial street the municipal building should be set back in order to provide for the wid— ening of the road if and when a new building is constructed. II 39 1 Entrance Monument 1 In spite of the fact that the Town is currently burdened with 1 financial obligations with which to provide adequate services, it is recommended that the Town Council cooperate with citizen 1 groups and other agencies in obtaining an entrance monument. This is needed to provide the Town's people with a sense of identity. It may not be possible to construct such a monu- ment immediately, However, the general acceptance of the concept should be adopted so that interested people could 1 work to this end in their efforts to acquire the necessary construction funds. Oil companies, for example, are always 1 looking for locations for signs. It may be that such a company or a group of companies in the industrial park may construct the monument if the Town would agree to maintain it. The cost of maintenance and the adverse effects that may come from a poorly maintained monument may be the greatest imped- iment in obtaining such a monument. 1 Library 1 A library is maintained by Pima County, in association with the school district. It is located south of the Jr. high school at ' the north end of the County Park. According to the American Library Association, a library building for a town the size of Marana should contain at least 2,000 square feet and should contain at least 10,000 1 volumes. Following is a table which shows the American Library Association's recommendations for library facilities. 1 1 1 1 40 . 1. 1 1 TABLE I GUIDELINES FOR LIBRARY FACILITIES Shelving Space I g ac P Estimated Size of Linear Amount of Additional Total I Population Book Feet of Floor Staff Work Space Floor Served Collection Shelving' Space Reader Space Space Needed' Space Under 2,499 ...10,000 vol. 1,300 linear 1,000 sq. ft.

This brief 16 -page report is based on standards set forth in ALA's, PUBLIC LIBRARY SERVICE; A GUIDE TO EVALUATION WITH MINIMUM STANDARDS. It is intended to provide interim standards for libraries serving populations of less than 50,000 until these libraries can meet the standards of ALA's PUBLIC LIBRARY SERVICE. I 1 Libraries in systems need only to provide shelving for basic collection plus number of books on loan from resource center at any one lime. s A standard library shelf equals 3 linear feet. i Space for circulation desk, heating and cooling equipment, multipurpose room, stairways, janitors' supplies, toilets, etc., I as required by community needs and the program of library services. 1 41 1 Library Plan. It is entirely likely that the amount of 1 floor space recommended by the American Library Association is more space than is needed in Marana at this time, but as 1 population increases the demand for library services can be expected to grow. 1 Until the funds become available with which to construct or to acquire a separate library building, the present arrange- ment with the County should be continued. Fire protection 1 Marana has no fire protection of its own. Up to the present time the Town Council has arranged with other fire districts for this service. Perhaps the best indicator of the adequacy of a community's fire defense is its Fire Insurance Rating. The agency respon- 1 sible for determining a community's Fire Rating is the Arizona Insurance Services Office (formerly the Arizona 1 Fire Rating Bureau). The rating assigned to a community is considered as a general indicator of the town's fire defense capability and is used by fire insurance companies as the basis for determining fire insurance premiums. The fire rating is applied to a community after a careful analysis of the town's fire fighting capability. The basic 1 factors considered by the agency in arriving at a community's fire rating are as follows: 1 1 1 1 1 1 1 42 1 1 Summary of Factors Considered In Determining A Fire Insurance Rating Factor % of Rating II Water Supply Capability 39 Fire Department 39 I Fire Services Communication System 9 (alarm system) Fire Safety Control 13 (adequacy of building laws, fire protection agency) 1 All communities, counties and districts within the State have been given a specific rating. 1 The ratings assigned range from one to ten, with a lower II number indicating a more favorable rating. Generally, a rating of 6 is considered acceptable for cities having vol- 1 unteer.departments. At present, Marana is assigned a number 10 rating. 1 The last detailed evaluation and rating for Marana was per— formed prior to its incorporation. At that time, significant II deductions were made because of deficiencies in the water system and fire department equipment and operation. The savings in the cost of fire insurance which home owners 1 receive as a result of an improvement of fire rating are sign— ificant. Following is a table showing the annual cost of insurance for a frame home valued at $20,000. Several rating 1 classes have been given to indicate the relative effect of a change in rating. 1 1 1 43 . i 1 Annual Cost Of Fire Insurance 1 By Rating Class : $20,000 1 Rating Annual Premium Cost 10 $91.60 ' 8 47.12 7 38.37 6 32.12 5 26.37 Thus, it can be seen that fire insurance premiums could be 1 reduced by almost one half (I) of present cost by gaining a .number 8 rating. Future Needs In light of the benefits which local residents may receive from an improvement in the rating number, Marano should 1 contact the Insurance Services Office and request their assistance in evaluating present conditions and formulating a program designed to improve the Town's rating. As an intermediate step, the Town should submit to the In— surance Services Office a supplementary rating application. Such an application may result in the re— classification of Marana from #10 to #9 B or possibly to #8, provided the Town Council moves to negotiate a mutual aid fire agreement 1 with Picture Rocks and Avra Valley Fire Districts. Under the law, all mutual aid agreements must be in the form of ' a written agreement in order for a town's liability insurance to be effective when fighting a fire outside of its corporate limits. Eventually the Town may find it advantageous to build its 1 own fire station and to equip it with tank trucks, hoses, etc. 44 , 1 1 In view of the fact that the water mains are not owned by the Town and the fact that there are no water mains in agr- 1 icultural areas,a large capacity water tank along with pumps and hoses will be needed as well as trucks that are equipped 1 with smaller tanks. The amount of time required to respond to a fire call is also I a factor that is taken into account in determining the ade— quacy of fire defenses. For this reason the station should 1 be located close to the central part of the community. While it is not necessary for the station to front on a major road II it should be located close to such a road. I Many small communities locate their fire station adjacent to or in connection with the town office building where some person is usually able to take calls and alert a volunteer 1 fire fighting crew and to even drive a fire truck to the scene of the fire while the crew is assembling. 1 Consideration should therefore be given to the location of 1 the fire station in connection with the civic complex at the intersection of Sanders and Moore Roads. 1 Listed below are the necessary items needed to achieve Pro— tection Class 8 or better. In order to achieve Protection 1 Class 9 it is not necessary to comply with Item #1. II 1. A minimum recognized water supply constitutes a network of mains and hydrants capable of delivering at least 1 250 gallons per minute (over and above maximum consumption) for a period of at least two hours. Where there are numerous commercial buildings, this minimum might be converted to at I least 500 gallons per minute for one hour (the same total quality of water but available at a greater flow rate.) 1 2. The fire department shall be organized on a sound, 1• 15 1 permanent basis under applicable laws. The Town shall in— 1 elude one person (usually with the title of chief) respon— sible for operation of the department. The department must serve an area with definite boundaries. If a municipality is not served by a fire department solely operated by or for the governing body of that municipality, the fire department pro — viding such service shall do so under a formal contract. When a fire departmentts service area involves one or more civil jurisdictions that are not a legal part of the service area, a contract should be executed with each jurisdiction 1 served by the fire department. There shall be available a written description, or a map, defining the boundaries within which a fire department res— ponds. 3. The department shall have an active membership which 1 provides a response of at least four members to alarms within ten miles. One of the four members required to respond to alarms may be the chief. The "alarms" referred to are first alarms for fires in structures. Records should be kept to substantiate response of members and apparatus to alarms of fire. 4. Training for all active members shall be conducted at least two hours every two months. 1 5. There shall be at least one piece of apparatus equip— ped with a pump and meeting the general criteria of N.F,P.A. 1901, "Automotive Fire Apparatus ", the minimum requirements for which are given below. Apparatus that is overloaded, especially in areas where rough roads are encountered, may receive no recognition. Apparatus shall be housed as to provide protection from the it 46 1 1 1 weather and from freezing where necessary. 1 To be considered pump apparatus should have the following: I (a) A permanently — mounted pump with capacity of at least 500 gallons per minute at 150 psi (or at 120 I psi for Class B pumpers). In lieu of a single ap- paratus, two pumping units (each capable of pumping at least 250 g.p.m. at 150 psi) operated as a single I engine company, and together capable of delivering an effective 250 g.p.m. stream at a distance of 1,000 1 feet from the water source, may be recognized. (b) A water tank of at least 150 — gallon capacity. In 1 municipalities without a recognized water supply, the tank should be at least 300 gallon capacity. (c) Sufficient 22 — inch (or equivalent) hose so that, I with the pump provided, the apparatus can deliver effective fire streams totaling 500 g.p.m. for a II distance of 500 feet from the water source and total — ing 250 g.p.m. for a distance 1,000 feet. II (d) Equipment (1) Two nozzles for 22 inch hose, each capable of ' discharging either a spray or a straight stream. (2) Two hydrant wrenches (3) One gates wye, 22 — inch to 14 inch. 1 (4) Two combination spanner wrenches for 22 inch and 12 inch couplings. I (5) 400 feet of 12 inch fire hose. (6) Two nozzles for 12 inch hose, each capable of I . discharging either a spray or a straight stream. (7) 150 feet of 3/4 or 1 inch fire department booster 1 hose, and a nozzle capable of discharging either spray or a straight stream. (s) Two portable fire extinguishers suitable for use on Class A, B and C fires. The minimum sizes should be 20 B.C. rating in water type extinguishers. 1 47 1 (9) One 12 foot (preferably 1 foot) fire department 1 type ladder with folding hooks. (10) One 24 foot fire department type extension lad— 1 ler. (11) One pick —head axe (6 pounds). (12) Two electric hand lights (4 volt minimum). (13) One Pike Pole (6 foot minimum). (14) One bolt cutter. (15) One claw tool (16) One crow bar (36 inch minimum). All buildings within five (5) miles over all weather roads from the fire station housing apparatus satisfying the above criteria, may receive Class 9 or better recognition. 1 The statements refer only to the fire insurance rating class— ification. City Shops 1 Storage facilities for the Town's maintenance equipment and 1 vehicles are presently located adjacent to the Town Hall near the intersection of Sanders and Moore Roads. The 2.5 acre site is considered adequate for the forseeable future, but since storage of equipment, culverts, etc., is not com— patible with Town buildings and the surrounding dwellings such storage should be provided in a separate area west of the Town buildings. Eventually the site should contain at 1 least 10 acres. See map on page 20. 1 Health Care Facilities An out — patient clinic has been established in Marana and is located on San Dario Road just north of Greez Road. The clinic provides a much needed service in a community that does not have sufficient population to warrant the retention 48 1 of a full time doctor with his staff. As the population increases, the clinic will probably grow in significance until it becomes feasible for the community to maintain full time medical services. 1 1 1 1 I/ 1 1 1 1 1 1 1 1 1 49 1 1 LAND USE PLAN Residential Land The proposed land use plan for Marana provides for two basic types of residential development within the residential area of the town. 1. High and medium density residential development t should be located around the present central business district, along San Dario Road and adjacent to the elementary and junior 1 high schools on Grier, Lon Adams, McDuff and Barnett Roads. This is the best place for apartments primarily because of the presence of the sewer or as it will be constructed. It will carry out the pattern of development that has already begun to take place and is consistent with the multi —core type of urban form. It will also be consistent with existing capacities of the streets, water and sewer systems. En—. couragement should also be given to the construction of high and medium density residential development around the civic 1 center at Moore and Sanders Roads. Other core centers may also develop in the future (such as at Trico — Marana and Luckett Roads or Avra Road or Sanders Road) and they should be treated similarly when they do. 1 2. Low density residential development should be located on the periphery of ttie two areas mentioned above and along the I streets as indicated on the land use plan. Development in low density areas should be limited to one — family detached dwellings. Farm dwellings should be located along existing° roads, but not in the interior of the farmsteads. II I The following land use plan shows proposed residential areas within the town. It should be noted that all of the land 1 50 1 indicated for residential purposes is located above the level of the Santa Cruz River flood plain. As a means of implementing the land use plan, it will be 1 necessary for the Town Council to confine the extension of water and sewer lines to the areas indicated for develop— ment and then only in an orderly manner. (See development code) The Town Council should be quick to point out the need to develop residential areas in an orderly manner as opposed to a "leap frog" scattered manner. The Council should ad— just its water and sewer line extension policies so that the developers are required to pay all of the cost of extending ' the lines from the existing lines to their building sites. Where this is done, builders tend to develop land that lies closest to existing facilities in order to avoid the cost of constructing long extensions. The multi —core form of urban development is thereby achieved, and the savings in taxes 11 for operation and maintenance of public facilities will be significant. All domestic water companies should be requested ' to comply with the Town's development code in this respect. Commercial Land Commercial uses in Marana should be clustered together in a compact manner, rather than being scattered throughout the ' Town. There are several types of commercial establishments in Marana, each of which has its own location requirements. Most of the establishments can be grouped into four general types, as follows: 1 1. Convenience Good Stores 2. Primary Shoppers' Goods and Specialty Goods Stores 3. Secondary Shoppers' Goods Stores 4. Highway and General Service Establishments 1. Convenience Goods Stores. Examples of convience goods stores are grocery stores and service stations. In 1 52 1 small communities (under 15,000 population) convenience goods t stores should be located in a central core area. In this way, the business district increases its power of cumulative 1 attraction. Stores that are scattered usually do only a limited volume of business. This explains why so many small communities begin to languish when their business community is allowed to scatter out. The old adage that two stores side by side support each other, is especially applicable to small communities like Mara Unfortunately, this natural characteristic is overlooked by merchants when they choose ' a site for their retail establishment that is separate and apart from the central area. They think that it will be to their advantage to locate off by themselves where the land is cheaper. As a result, both the merchants and the community suffer. The success of the convenience goods stores adjacent to Honea Heights Subdivision has been made possible by the presence of the people who live in the subdivision. While convenience 1 stores have been successful, that same degree of success would not likely occur if the store were a primary shoppers goods L store. While it is not possible, nor would it even be desirable to P adopt ordinances to force stores to located close together, the Town Council and Planning Commission should give new stores all possible encouragement to cluster together perfer— ably in an organized manner such as in a regional shopping center. A zoning system that encourages vacant land to be used automatically for a purpose similar to an existing ad— ' jacent land use will tend to accomplish this in a relatively uncomplicated manner. ' 2. Primary Shoppers Goods and Specialty Goods Stores. In a small town, it is particularly important for primary shoppers goods stores, such as clothing, jewelry and hard- 5 3 1 ware stores to be located close together. Customers like to be able to walk from one store to another in comparing ' goods. They dislike having to walk long distances between stores or to be forced to choose from a narrow selection 1 of goods. Wherever shopper goods stores . are not situated in the man— ner described, people tend to by —pass local stores in favor of shopping areas which do conform to the described sit— uation, despite the fact that the facilities may be many miles further away. "Primary shoppers" goods stores (e.g. apparel shops) and ' specialty goods stores that do not require long street front— ages should occupy the prime location in the core area and should be located close together for the convenience of the buying public. This is crucial to a business district such as the business district of Marana. Where they are not lo— cated within convenient walking distance, shoppers often go to adjacent cities to do their shopping. 3. Secondary Shoppers Goods Stores. Automobile sales lots and farm machinery sales establishments are examples of secondary shoppers' goods stores. Because they require long street frontages and hurt the close interaction of business when located in the center of the core area, they should be located on the fringe of, but not right in a core area. 11 It would be an added convenience to the citizens of Marana and ' an advantage to the merchants if the business districts were to grow in a compact manner. By organizing commercial deve— lopment within the town so as to take advantage of the proper natural features of shopping center design, future prospects for better commercial districts in Marana can be greatly en— ' hanced for everyone. It should be borne in mind in attempting to determine the 54 amount of land that should be devoted to retail and service enterprises, that the amount of land which will be used for retail and commercial purposes will likely never exceed four ' percent of the land that is developed into urban uses. De— signating excessive amounts of vacant or residential land 1 for commercial purposes does not encourage new business. Rather, it discourages new businesses, particularly if new businesses are located in widely scattere.l areas. The secret of a superior commercial community lies in its compactness. 4. Highway and General Service Establishments. Motels, service stations, cafe's and fast food establishments are , examples of highway service establishments. They are the type of commercial uses which cater to the traveling public. 1 They must be located where they are easily assessable to major transportation routes. Generally, highway service establish— ments (except restaurants) require long street frontages similar II to secondary shoppers' goods stores. Accordingly, most high— way service establishments should be situated close to the 1 freeway interchanges and other major intersections as well as close to other retail outlets and businesses. ' Examples of other service establishments are professional offices, governmental offices, barber shops, and banks. Pro— fessional and governmental offices should be located either in the core of a business district or else immediately ad— jacent to the core of a business district. 1 Industrial Land The ro ortion of developed land that is used for industrial P P p and heavy commercial purposes in the average community nor— mally ranges from 10 to 20 percent. In Marana, 47 acres or approximately 5.3 percent of the developed land is considered as industrial land. As yet, the majority of industrial uses are II associated with agricultural activities, some of which are locat— ed outside of the Town. Most of the industrial land in Marana , 55 1 1 is being used for the ginning and storing of cotton. No attempt has been made to date, to organize and build a pre— constructed industrial park with landscaping, hard sur- 1 faced streets and water and sewer facilities already con— structed. While the Town, itself cannot become involved in such a project financially it should facilitate the pro— gram in the event that some industry is willing to settle in the area. The area lying along the east side of the 1 Southern Pacific Railroad between the Tangerine and Trico— Marana interchanges would be suitable for the development of industrial parks as well as free standl.ng industry. The area around the Avra Valley Airport might also be suitable for such use. These areas are readily accessible to other parts of the community, and yet such uses will not pre —empt land that is better suited for retail and highway service uses, nor for agricultural uses. Also, expansion possibilities in the area are almost limitless. The most serious impediment at this time is the limitation of one —way vehicular traffic on the east side of I -10 between the Tangerine interchange and Moore Road. Simultaneously with an effort to interest a private developer to construct ' an industrial park should be an effort to obtain funds with which to construct a two —way road between the Tangerine 1 and Trico — Marana interchanges. Industrial Park 1 Nearly all industries need domestic water, sewage, and tran— sportation facilities. Some industries need a considerable amount of land for storage of supplies and materials. Others 1 need exposure along a major street. An increasingly larger percentage of industrial enterprises are becoming concerned 1 with the appearance of their surroundings. They are even be— 56 1 coming willing to forego frontage along highways in favor 1 of well landscaped and well maintained grounds around their buildings. Many industries can best satisfy their location 1 requirements in a planned industrial subdivision or large scale development, where several enterprises can be accommo— ' dated and where the streets, utilities, and landscaping around the buildings can be provided in the most economical manner. Residential development should not be allowed to pre —empt industrial land. Initially, the project should contain from five to ten acres, but it should be located 1 where it can be readily expanded. Following is a sketch of an industrial park, the likes of which should be developed 1 in Marana. 1 20, 15 4 5 2 3 ACRES 30 I • 1 3 10 4 1 • III 11 _ 1 . . . . 1 3 Wil 1 II As the town grows in population and cotton farming declines 1 it may be advisable to convert the present producer's cotton gin and storage yard into a shopping renter. This of course, 1 should be done by the owners of the land in response to chang— ing economic conditions and not by any compulsion or false II incentives on the part of the Town government. Provisions should also be made to develop some of the land II around the landing fields that are located near the inter— section of the Avra Valley and Sanders roads to fly —in industry. 1 Some manufacturersof light weight components such as elec— tronic equipment and high fashion clothing perfer to be lo— II cated adjacent to airport runwa s. The Town should also fac— y ilitate the development of a fly —in industrial park in this area. 1 57 1 II II Facilitating industrial development is a hard and arduous process. Success comes only through the use of initiative, II 'ti individuals and imagination and ingenuity. Contacts wi .i individuals i corporations that are interested in both developing indus— II trial parks and in establishing manufacturing or industrial establishments should also be made. Also offer to assist I desirable industries by facilitating the use of municipal bonds along with assisting industry in arranging finances I through the Small Business Administration as well as through other more conventional sources should be adopted as a mat— ter of policy. However, fly —by —night and other risky ven— tures that cannot stand on their own financially should be avoided. 1 n view of the fact that a cement plant is located at Rillito In view p , II it may even be possible to attract manufacturing establish— ments to the area that use cement in their products such as II cement building blocks and prestressed concrete beams. It should be borne in mind that any effort devoted toward r industrial development should be specific and vigorous rather than general and lackadaisical. Public and Semi — Public Land -- Institutional Land ' Public and semi — public land uses (except for airports) occupy approximately 77 acres within the community. This amounts to approximately 9.5 percent of the developed land which is less than the percentage of developed land used for public and II semi— public purposes in most communities. II Since a county park already exists in the area adjacent to the Jr. High School, the need for a public park has been sat— ' isfied in that area. A similar tract of land should be ac— quired in connection with the Town Hall in order to meet the II needs of the people who will live in that area. Eventually, II 58 1 an elementary school may also be warranted if the area around 1 the Town Hall is developed into urban uses in which case the park should be located adjacent to the school. Through such a plan, the park and school can complement each other, and be adjacent to dwellings. Much more beneficial use can be obtained from a school and town park located ad- jacent to each other than when they are located in separate ' parts of the town. In the event I h v nt that a fire station should be acquired it should be located in the urban cluster around the Trico — Marana interchange, the Town Hall or where the Trico — Marana and Sanders roads intersect. While it may not be advisable to acquire the sites for future public facilities at this time, tentative sites should be 1 selected. After the sites have been tentatively selected, arrangements should be made with the owners of the land to notify the town and the school board prior to any further development which they may propose, so that the land oan be acquired, if necessary, before private buildings are con— structed on the land. 1 Agricultural Land The amount of cultivated land devoted to agriculture in Marana is approximately 9050 acres. The amount of non—cultivated land is approximately 8440 acres. It was the opportunity to drill wells and to divert water on— 1 to the land that accounts for the existence of the town of Marana in the first place. It is also important that as 1 much agricultural land as possible be retained in agricultural use. Otherwise, a major element of the economic base of the 1 community will erode away. 1 59 1 1 The amount of agricultural land which has been available for small parcel, residential or commercial use is very limited. Because of this fact, the market value of building lots will tend to increase particularly if the demand for 1 housing is significant. Since the development of industry often results in the creation of jobs followed by an increase in demand for building lots on which to construct houses for the job holders, it should be expected that the market value of the lots will rise. If this occurs ' it will be necessary for builders to leap frog out into the surrounding agricultural land for building sites 1 which they can afford to buy unless cooperation can be ob— tained from the county assessor and the Cortaro Water Users ' Association. In order to prevent the cost of building lots from skyrocketing, ' it will be necessary for the county assessor to increase the assessed evaluation of the building lots as the market value of the lots increases. This has not been done in the past in 11 ' Arizona to the extent that it should have been done. Consequently, the market value of agricultural land has often increased along witI the market value of building sites. When assessed valuations are kept up to date with market value the supply of land for building sites tends to stay in balance with the demand. It should also be remembered that taxes come from various 1 sources but are spent on people and their needs. Land which is devoted to agricultural use does not require very ' many dollars to maintain the necessary services simply be— cause the required services are minimal. It is people that need public services and not the agricultural products or ' land except for irrigation water which is usually paid for by the growers. Because of this, it becomes doubly necessary for the county assessor to increase the assessed valuation annually on building lots as market value increases or else 1 the farmers will be forced into paying for most of the ser— vices which the more numerous non—farm families receive.* ' * This will occur because the market value on farm land will also increase and by law will eventually be reflected in increased assessed valuations on such land. 1 60 t Wherever property owners are able to hoard or keep their land , without having to pay taxes on it, based on market value, the market value of the land tends to go up much faster than the , taxes. Thus, the owners become reluctant to sell their lots. As a result, artificial scarcity is created. Regardless of the number of building lots in a city the owners often refuse to sell them except at increasingly higher prices. Eventually, the prices increase to suchan extent that it is. no longer pos— sible for the county assessor to increase the assessed valua— tion to the proper amount without driving the owners of agr— icultural land out of business. This phenomenon occurs as a result of the law of supply and demand or the free market sys— 1 tem and will always occur when assessed valuations on lots and land are not kept up —to —date each year with market value. This , accounts for the fact that farm land is often greatly over taxed in relation to need for services while other property is under , taxed. When the assessed valuation on the land is increased yearly in direct proportion to the market value, as should be done, the market value on farm land tends to remain stable and land , speculation does not become a problem, nor does the loss of so much prime agricultural land due to urban scatterization 1 become a problem which soil conservation officials have com— plained about so much. Only land speculators or farmers, turn— ed speculators, make money when assessed valuations are not increased in line with market value and that is done at the expense of bonifide farmers and ranchers. Should the demand for building sites ever decrease significant— 1 ly, the resulting decrease in market value on farm land could cause financial distress to people who have purchased land on 1 borrowed money. 61 1 1 II Any success which the Town may have in attracting industry into the community will likely have the effect of eroding 1 the agricultural economy due to the scattering of dwellings into agricultural land unless assessed valuations are kept II up —to —date annually with market value. This will not occur . nearly as much if the county assessor is willing to adjust I assessed valuations on building sites up or down, annually in direct proportion to market value. In the event of the II county assessor's willingness to do so, encouragement should be given to the construction of dwellings in a fairly com— pact manner, rather than to scatter them out over the farm II lands as shown in the scattered type of urban form. 1 Since agriculture has been and will likely continue to con— stitute a large part of the economic base of the community, 1 it is vital that the amount of urban scatterization be con— trolled to the maximum extent possible. II Following is a table showing the legislative class and as— sessment percentage of various types of tangible property. II 1 TITLE 42 OF THE ARIZONA REVISED STATUTES REQUIRES THAT ALL PROPERTY BE VALUED ANNUALLY AT MARKET VALUE I MARKET VALUE AND FULL CASH VALUE ARE DEFINED AS BEING SYNONYMOUS The legislative class applicable to each property is based on the use of property. Legislative Assessment Class Percentage II 3 27% All real property used for commercial or industrial purposes. 4 18% All real property used for agricultural purposes and all vacant land. I 5 6 15% All owner occupied real property used for residential purposes. 21% All leased or rented real property used for residential purposes. 7 8% All real property qualifying for a designation as historical property and listed in the National Registry of Historic Places. I If the property is used for a single purpose as defined above. the appropriate legislative class number and assessment percentage will be shown on the front of the card. If two or more legislative class definitions apply to a single property. a combined assessment percentage will be reflected on the front of the card. For example: If 50% of the value of the property reflects owner occupied residential use and 50% commercial or industrial use, a mixed assessment ratio of 21% would be I shown on the front of the card. The abbreviation "IMPRV" means improvements and includes major structures such as homes, apartments. townhouses. stores, factories. and miscellaneous structures; such as sheds, barns. mobile home slabs and /or hook -ups etc. If you wish to appeal the value or classification of your property you may obtain: PROTEST FORM 130 FROM THE ASSESSORS OFFICE a LL APPEALS MUST BE RECEIVED IN THE ASSESSOR'S OFFICE ON OR BEFORE FEBRUARY 15. TARS 42 -22'1_ 1 1 62 1 But, assessed valuations have not been raised annually in step 1 with the market value of the lots in many areas. Rather, assessed valuations have stabilized while market values have skyrocketed. 1 It would also be best if all assessment percentages were the same, except perhaps for #7 above. 1 While it would be better if all of the percentages were the same, it is not critical to the achievement of the goal of carrying out the multi —core type of urban form in Marana. What is critical, is that assessed valuations on land and 1 lots lying within the area designated on the plan for urban uses be increased or decreased annually, strictly on the 1 basis of market value. the Ad Valorem Tax on Land Development. Influence of ment. h A V l p Wherever taxes on land have not been kept up —to —date with market value or wherever taxes have been based on use or productivity speculators have been able to make huge profits 1 because the market value has gone up much faster than the taxes. It is not necessary to make productive use of the 1 land when assessed valuations on land are based on productiv— ity rather than market value. In fact, it actually pen— 1 alizes an owner to make productive use of his land. Conse— quently, in Mexico where land has been taxed on the basis of productivity, a relatively few families have been able to acquire much of the land. Hopefully, the county assessor will be successful in up— dating assessed valuations on land annually as long as the demand 1 for housing remains vigorous. If the Town Council will require all developers to construct all improvements in their subdivisions at the developers ex— II pense, and if the Cortaro Water Users Association also requires developers to install all improvements at their expense and 63 1 II II the county assessor is able to keep assessed valuations on building lots up —to —date with market value the probability 1 that the land use plan can be realized will be greatly en— hanced. 1 On the other hand, if the municipality, or Cortaro Water Users 1 association permits or encourages the expansion of the water system beyond boundaries shown on the land use plan or if the 1 county assessor does not update assessed valuations on building lots in the area designated for residential uses as shown on II the plan, then scatterization and urban sprawl will take place and the cost of providing necessary public services to 1 widely scattered dwellings will increase, while the agricultural economy of the area will begin to erode. Only a relatively few ' non —farm homes would substantially reduce the use of airplanes in the growing and harvesting of cotton. 1 Neighborhoods II Most people think of a city or town as a single organism. II Actually, however almost any community having a population of 2,000 or more people takes on a cellular structure. This I is a natural process. The boundaries of these cells or neighborhoods usually con — II sist of natural features such as mountains, hillsides, streams and lakes, or they may consist of man made features II such as commercial areas, industrial areas, railroads, major streets and similar areas or uses. II It is important that this natural tendency be recognized as early as possible in the preparation of a Comprehensive plan I so that the major streets, railroads, community buildings and other man made uses of land may be properly planned and 1 1 64 1 located with respect to the natural characteristics of the 1 area and with respect to other uses. 1 Ideally, a residential neighborhood should cottain approximately 200 to 400 acres of land or enough land to accommodate 600 to 1 700 families which in turn will have about the same number of elementary school students needed to fill one elementary school 1 when the land is fully urbanized.* The elementary school should be located in the central area of the neighborhood thereby avoid— ing the necessity of small children having to cross busy, high— speed arterial or collector roads. Each neighborhood should also contain a variety of housing types rather than all multiple housing units or single family dwellings which accommodate families of the same or similar economic or ethnic make up. Children mature and 1 become better citizens when they live and associate with children of dissimilar economic and ethnic make up. The neighborhood also gives children an identy and support not otherwise available. They become more than a mere number. It is recognized that Marana does not as yet contain enough people or families to make the need for neighborhood delinia— tion apparent. However, three neighborhoods have been re— cognized and provided for in the plan, one near the present 1 elementary school, the other around the Honea Heights Sub— division and Town Hall, and the other (really more of a 1 neighborhood in embryo) in the area known as Berry Acres. * At age 15 a subdivision will contain an average of 1.5 elementary school students per dwelling unit. At age 35 the number of elementary school students will have decreased to an average of approximately .5 students per dwelling unit. The average then increases again to approximately 1.0 per dwelling unit. Marana schools may have fewer than 1.0 per unit at the present time. Six hundred to seven hundred students call for three teacher stations per grade of 25 students each in elementary schools that contain 8 grades plus a kindergarten. 65 1 1 1 Following are diagrams which illustrates some of the prin— ciples of a good neighborhood layout, There is also a map 1 which shows how the Town should be delineated into three neighborhoods. . 1 N S E R T Il 1 1 1 1 n fta� o f laid z 14°' Into I ; � 1 () S HOPPING CENTER ( � 4 Neig hborhood x I W ' �1 Q U m i t 9 I 0 14i 3 FORMAL DEVELOPMENT I ` ' P A R K I N G I.

It expresses a way of life. Unpainted and neglected buildings and unkept I lots express a life style just as surely as do neat and tidy premises. Il Housing conditions are not necessarily commensurate with income. While the level of income might be expected to have 1 a bearing on the condition of housing within a community, it actually has a greater bearing on the size of the houses 1 rather than on the appearance of the houses or the tidiness of the yards around them. There are approximately 450 dwel— 1 ling units in the Town, approximately 100 of which should be classified as deteriorated or delapidated. Most of these units are scattered throughout the community and are still I in use. 1 Several new homes have been added to the housing supply since 1970. The primary effort in providing housing has been de— 1 voted to the construction of new single — family houses, or the moving of mobile homes onto lots in subdivisions or on I lots which have been created by severing them from larger tracts through the use of metes and bounds descriptions. 1 Several conditions have contributed to substandard housing conditions. Generally, low income, seasonal employment, 111 lack of initiative and pride in home maintenance, and the lack of codes, ordinances, and home inspections are the chief 1 contributors. However, the lack of fee simple ownership of the lot by the owner of the house is the most serious draw I back that carries over year after year. It is only natural for residents to refrain from improving their lots when they rent their lots rather than own them. The shortage of mort- 1 1 68 1 gage money, high interest rates, relatively high costs of 1 building materials, and the lack of skilled labor and enter— prise have also discouraged many homeowners from building 1 new houses or from making repairs and improvements to exist— ing homes. The primary objective of the citizens of Marana regarding housing should be to create and maintain a living environ— ment of sustained desirability and environmental appeal to the end that every family will be able to live in a decent home. In order to accomplish this, several steps must be taken. Specifically, the following programs should be adopted. 1 1. A conservation program should be instituted in Marana 1 which is designed to encourage homeowners to improve and conserve their present home. This is the primary job of a shade tree and beautification committee. Such a program should be carried forward on a continuing basis. Use of professional persons in landscaping_ and environmental design • from the Extension Service and the University of Arizona should also be encouraged. 1 2. The conventional method of financing and construct— ' ing houses should be retained for families whose income is sufficient to warrant the acquisition of a house or mobile home costing more than $20.000. The demand for this type of housing will likely account for most of the additional housing 1 in the town, 3. Private developers should be encouraged to use un— developed lots with the thought in mind of constructing houses on them rather than to scatter the homes out throughout agr— 1 icultural lands. The self help section of the Farmers Home Administration may be found to be useful in this area because this is a program designed to assist lower income families in acquiring ownership of their homes. 69 IF 1 4. Private developers should be encouraged to build manufactured or prefabricated homes, with and without fin- ancial assistance from the U.S. Department of Housing and Urban Development or Farmers Home Administration. Builders ' should be able to manufacture multiple -unit buildings con taining from 800 to 1,000 square feet of living space each; transport the homes to Marana and place them on a permanent foundation with all utilities connected, for less than ' $25,000. This is much less than the cost of erecting build- ings that are constructed on building sites in the conven- tional manner. 5. Private developers should be encouraged to construct 1 mobile home parks which comply with guidelines shown in the Property Development Standards promulgated by the Land Deve- 1 lopment Division of the Mobile Homes Manufacturers Associa- tion with offices located at 20 N. Macker Drive Chicago I11. 6. It is only people natural for eo le who do not own their lots to refrain from constructing substantial housing on the lots or from even making improvements on existing dwellings. If the families who live on rented land owned both the lots 1 and the dwellings, chances are the occupants would be more interested in maintaining their premises in better condition. ' One way by which this might be accomplished would be to build a planned unit development or condominiums so that the occupants could own their own dwellings. It is recognized that the traditional life style of many t families is so strong that the responsibilities of private ownership of their dwellings may not be acceptable in the form of planned unit development or condominium owner- ship. 1 1 1 70 1 1 7. Building, plumbing and housing codes should be 1 enforced, The owners of existing substandard houses who are financially unable to remodel their own homes should be encouraged to seek outside assistance. The average income per household in Marana has been estimated 1 to be approximately $12,000 per year (1978), Sound financial prac— tice indicates that families should not spend over 25 percent 1 of their income for housing. Accordingly, the average fam— ily in Marana would be justified in spending up to $300.00 1 per month for housing under either rental or ownership status. Since it costs $35.00 to $40.00 per square foot to build a conventional single — family detached house which conforms to the uniform building code, the average family can not afford to build a home containing much uore than 1,000 square feet. Approximately one half of the number of new families cannot afford to buy or rent houses containing even 1,000 square 1 feet of usable floor space without financial assistance from some source. Approximately one fourth of the families will likely not be able to afford a house containing more than 750 square feet, yet most of them will need at least 1,000 square feet. It should also be remembered that some families are currently 1 living in inadequate housing. These families need houses as much or more, than the families that have higher incomes. In view of the fact that most low and moderate income families are not familiar with all of the complicated procedures that must be followed in arranging for building sites, building material and financing and labor, the services of a knowledge— able person to assist them would be helpful; otherwise, dis— advantaged families may not be able to acquire a home that meets the goal of making it possible for all families to 1 have a decent house in which to live. 1 71 1 1 Financial institutions such as banks and savings and loan companies should be encouraged to provide the services of ' such knowledgable persons. The school district might also be helpful in disseminating this type of financial knowledge 1 and understanding. 1 A community which expects to grow, improve its economy, at— tract new industry and provide a decent environment in which 1 to live cannot afford to neglect its housing supply. A major task of the Town Council should be to overcome the 1 impediments that stand in the way of achieving the goal of a decent home for every family. They should serve as a 1 catalyst in motivating all essential participants in the housing program in a manner that will achieve results. 1 While the program has been outlined above in general terms, in the final analysis, the task is of such a nature that it 1 is not possible to outline it in detail. Much will depend upon the resourcefulness and persistent effort of the Council, as they address themselves to the task. 1 1 1 1 1 1 1 72 1 1 IMPLEMENTING THE PLAN 1 As outlined in the Laws of Arizona, the basic purpose of the Comprehensive Plan is to guide changes and development that occur within a town to the end that the town will become an increasingly more convenient, healthful and safer place in which to work and live. However comprehensive plan is not unlike a blueprint of a building. It is not self— 1 fulfilling. Whether or not the plan accomplishes its purpose depends upon the acts of the people and their institutions. 1 Each house, business or industry comes about one at a time. The primary objective should be to fit them together in such a way that a practical and satisfactory scheme of municipal development will occur. Accordingly, the next step in the planning process is to develop, adopt or update imple— menting programs which are necessary to accomplish the 1 purposes of the plan. The devices or tools which may be used to implement a Compre— hensive Plan are: 1. An Advocacy Program 2. A Taxing Policy 1 3. A Development Code. 4. A Multi —Year Improvement Program 1 1. Advocacy Program. A little reflection on the content of the Comprehensive Plan and implementing devices will reveal that it will be necessary for all of the partici— pants in the development and administration of the plan to become advocates of the plan. Advocates should include mem— bers of the planning advisory committee, the town council, the 1 1 73 1 ' planning commission and the administrative personnel, the Cortaro Water Users Association and the School Board, ' They must do more than let nature take its course and do nothing. They must actively seek industry which will locate ' in the designated areas. They must actively seek to preserve and enhance agriculture, the production of crops and livestock and the distribution and marketing thereof. They must actively seek developers ' who will construct decent housing in the locations set forth in the plan. They must actively seek commercial development fully realizing that two stores when located side by side will always do more than twice as much business as one, that the gravitational pull of a business district is directly proportional to the number of square feet of floor space de- ll voted to business, and that the business district must be compactly constructed, rather than scattered, so that it is possible for women, who do 800 or more of the buying, to be able to walk from one store to another conveniently and with- out having to drive from one store to another. They must actively seek to develop a program that will re- charge the underground water supply with flood waters which will otherwise go on down stream and be wasted, ' They must actively seek funds with which to construct an identi- fication monument for the Town as well as other needed facilit- 1 ies as listed in the multi -year improvement program. They must actively solicit the cooperation of the county asses- sor in keeping assessed valuations on land equal to assessed valuation on all other kinds of tangible property as outlined in this report. They must actively seek to cooperate with the schools, the county and other public and private agencies in finding ways by which needed services can be supplied most efficiently, econ- omically and appropriately, 74 1 It will be in the seeking that community pride will develop. It will be in what the people do for the community that will make living pleasant and meaningful and not what the Town does for them. If an advocacy program is not undertaken chances are a terrible thing will happen -- the Town will not be much better off than if the council had not gone to the trouble and expense of pre— paring the plan in the first place. Per capita, cost of government tends to increase as the number 1 of people in the governmental unit increases because it is only natural for people to think that the larger the govern— 1 mental unit the better it can afford to pay for services. Hence, the demand for services increases. While taxes come II from several sources, the revenues are spent on people and their demands. This has been the case in every city and town which have tended to exceed their needs. Hopefully, the demands 1 in Marana will be no greater than that which the people of Marana are willing and able to pay for mostly on a pay as 1 you go bases. A Comprehensive Plan, in and of itself rarely gives rise to controversy. It is only when town officials begin to imple— ment the plan that controversy emerges. 1 Some people would like to see the Town develop., but when the costand inconvenience thatare connected with the development actually comes to their attention many peop1.e mis— understanding ; resist or resent the actions needed to bring it about. In almost all instances it is the cost that people object to most, hence their demands should be circumspect. One of the primary purposes of planning in the first place is 1 to make the most efficient use of land and to try to integrate each project, whether publicly or privately owned, with all 1 other aspects of urban development to the end that efficiency and economy in the process of development will be achieved. As is often the case, some people are benefited more than 75 ' others. Some may be actually hurt. There is no possible way that everyone can be benefited to the same extent. Con— ' sequently, the general policy should be to make sure that the developer of each dwelling, each subdivision and each 1 new street stands as much of the costs as feasible because any costs which developers do not assume, must be assumed by 1 others. It is only natural for developers to try to avoid having to pay II any more construction or maintenance cost than they are re— quired to pay. Nor, are most people willing to give land for the benefit of others without compensation. Fairness and equity can best be achieved by attaching as much of the costs of a development to the developer as is possible, and to so organize development in such a way that the most good, to the most people, over the longest period of time can be achieved. Moreover, all policies, codes and ordinances ' relating to the development, maintenance and operation of urban use of land should be prepared with this thought upper— most in mind. It is not always politically feasible to adopt implementing devices that will bring about the plan in the most expeditious manner because all people do not view a particular program ' in the same light. It may therefore be necessary to adopt a regulation that is politically feasible, yet not be as ' achievement oriented as one may wish, pending the time when a more achievement oriented regulation can be adopted. This is particularly true of zoning. Also, there is often more than one way to achieve an objective. While one alternative may be acceptable to affected property owners, others may not be acceptable. The objective should be to select the method or alternative that will achieve the goals and objectives with r the least possible disagreement. This is not always possible to anticipate until the time comes to address the issues and even then it may be difficult. !Li 2. Taxing Policy. It should be recognized that the transportation plan and the public facilities plan depends to a large extent upon the use to which the land in Marana is put. The street system as well as street widths to accommodate agricultural uses are altogether different than for residen— ' tial, commercial, or industrial uses. Likewise, the use to which land is put has a great bearing on the nature and type of public facilities. It is people that use both roads and public facilities. Yet the presence of a street or a school also has an influence on where people choose to live and the use to which land is put. This inter— 1 reaction can be observed in every city and town in the country where society is free to live where its members want to live. 1 Cost of land is one of the primary considerations that every family takes into account in selecting a place to live. In commercial areas, in large communities, land often costs from $50,000 to $100,000 or more per building site, while the cost 1 of good residential property should sell for $5,000 to $10,000 per lot, The actual cost is often more than a young family can , afford to pay. Consequently, most communities have large tracts of vacant land interspersed with subdivisions and commercial ' buildings which become difficult to make use of. As industry that employs people moves into a community, the demand for 111 building sites increases along with the price. Landowners soon begin to speculate on their land. It is the increase in price in the central part of a community that causes residen— 1 tial development to scatter out. Home builders are forced to look for building sites wherever the owners are willing to sell their land for a price which builders can afford to pay. Sometimes the price spiral becomes so great that it is diffi— cult to find building land closer than several miles from the central part of a city. 7 ,r i While the foregoing explanation applies most dramatically to cities like Tucson, it also applies to some extent to towns the ' size of Marana. Scattered buildings and subdivisions require the installation of expensive improvements which the tax payers must absorb unless the improvements are paid for by the developers and homeowners. This explains why taxes increase as urban sprawl spreads. Fortunately, there is a way whereby most of the added costs can be avoided. The county assessor should be asked to keep assessed valuations ' on land and building lots up to date with market value each year. When landowners learn that assessed valuations on their land along with their taxes increases or decreases in direct proportion to the market value of the lots, two actions take place: (a) the market value of the land tends to remain stable, ' and (b) building lots can be had for a price developers can afford to pay. On the other hand, when market value increases but not assessed valuations, then speculation occurs, causing most landowners to hold on to their land. This in turn brings about artificial scarcity, along with "leap — frog" scattered development. Each year the chief administrative officer of the town should contact the county assessor to make sure that assessed value— !' tions on the land and building lots are kept up to date with market value, particularly in the area designated for urban 1 development. If the assessor does not keep assessed valuations up to date with market value and the number of people living in the area increases, then the market value of the land and building sites will also increase in direct proportion to the demand for such building sites. Should this occur, the entire ' plan will be thwarted. Scatterization and urban sprawl will ■ 78 1 take place, the cost of public improvements will increase and the town will rapidly lose its agricultural base. Marana has too much at stake to let this happen. No one wins in land 1 speculation except the speculator, while the farmers are the people who are saddled with most of the cost. 1 3. Development Code. A development code includes sev— eral parts as follows: a. Zoning requirements and map b. Subdivision requirements c. Large scale development requirements d. Procedural and administrative guidelines 1 e. Water and sewer main extension policies. These parts are treated in further detail as follows: 1 a. Zoning requirements and map. A zoning ordinance has been included as part of the development code. However, the ordinance that has already been adopted will continue to be used as the zoning ordinance for Marana rather than to alter it significantly. at b. Subdivision requirements. The regulations that have already been adopted are believed to be adequate for the purpose. However, an additional section pertaining to large scale developments has been added to the code in order to pro— vide the necessary procedures that must be followed. This applies to planned unit developments, condominium projects, planned shopping centers, planned industrial parks, and other 1 such large scale developments. e scale development re uirements It is c. Larg scal q os— p sible to avoid an increase in taxes to provide services as well as improvements to residential commercial and industrial development and at the same time to assure superior mainte— nance. This can be accomplished by encouraging the developers 1 1 79 11 II 1 of residential, commercial and industrial properties to under — take planned unit developments for one — family dwellings and I I planned condominium projects for multiple dwellings, shopping centers or industrial parks. Funds with which to pay for ser— vices are provided through the assessing of association dues by a homeowners' or property owners' association rather than for the town to levy taxes on all property owners to pay for I the services, as is generally the case in conventional sub — divisions or lot —by —lot' development. II Large scale developments will likely be more complicated for developers to construct than conventional subdivisions until , they become familiar with the approval process. However, the II benefits far outweigh the drawbacks. d. Procedural and administrative guidelines. These II have been included as an integral part of the subjects dealing with zoning, subdivision requirements and large scale devel— opments. I e, Water and Sewer Main Extension Policies. In view ct that the Cortaro Water Users' Association provides most of the water for both domestic and irrigation purposes, II it will be necessary for developers to make arrangements with that agency for domestic water or else make their own II arrangements with the State Water Commission to drill wells. II 4. Multi —Year Improvement Program. A multi —year improve— ment program also includes several parts as follows: I a. A tentative multi —year maintenance and operation budget. II b. A document sometimes called a capital improvement program designed to facilitate the orderly develop— ' ment of public facilities in harmony with the II Comprehensive Plan. 80 1 1 c. A list showing a priority of need for the facilities 1 that will extend over succesive three -year time spans. 1 The multi -year improvement program contains a list of public improvements that should be undertaken by the town according to ' priority of need and ability to pay for them, including improve- ments which are constructed on a pay -as- you -go basis as well as those involving long term financing. It also includes im- provements that are undertaken by the town which are paid for by the State or Federal government. However, it does not in- elude improvements or projects which are constructed within the town when financed entirely by other agencies such as school II buildings, state highways and water lines which may be owned and controlled by the Cortaro Water Users' Association. 1 The safe limit of debt services (principal and interest) which a town should not exceed is 25% of the town's annual income for operation and maintenance. Only under unusual and pressing need should a community exceed such an 1 amount. In other words, cities and towns should not necessarily try to finance all of its capital improvement needs on a pay -as- you -go basis. On the other hand, communities should not become so heavily indebted that necessary and essential operations and maintenances functions cannot be carried on for lack of funds. ' A town should always provide a financial cushion on which it 1 may draw in the event of a natural disaster. Under no cir- cumstances should a town spend more than its available reve- nues without going through the process of a bond election. Experience has shown that debt service covering principal and interest of up to 25% of revenues devoted to operation ' and maintenance is usually a safe limit. 1 81 11 1 1 II All annual budgets should be prepared for an additional three to I g P P five years beyond the coming year. One more year should then be added to the tentative budget when finalizing the budget for the coming year. II Town budgets should always be prepared in the light of the town's financial ability to pay its expenses and then the town council 1 should make it standard practice for all department to keep their budgets. I . A carefully prepared budget is the best method of obtaining the II most for the money and the multi —year improvement program should become an integral part of the annual budget. 1 The time span covered by the multi —year improvement program should be from three to five years. This forces the budget officer to II consider more than one year. It also generates stability in the budget— making process and helps to keep the town on a sound finan - 1 cial footing. It also provides protection against special interest groups in I the event that an effort should be made to convince the town coun— cil to set aside its orderly budget process for some special pro— ' ject that is less necessary than others. 1 Following is a proposed multi —year assets improvement program for the ensuing three years with more tentative budgets for subsequent years. 1 II 1 1 82 II 1 PROPOSED MULTI YEAR ASSETS IMPROVEMENT PROGRAM 1 PHASE I: 1980 -1982 TRANSPORTATION PROJECTS 1 -01 Reconstruction of Sandy Road from Morgan to Steele. 1 -02 Paving of two lanes of Moore Road for 2.0 miles from San Dario Road to I -10, primarily for dust control. 1 -03 Widening of San Dario Road to four lanes, from Trico - Marana Road to Grier Road. 1 -04 Renaming of selected streets as follows: From: To: Trico- Marana Road Sam Chu Boulevard Avra Street Amole Circle and Adonis Road Avra Lane Price Lane Sandario Road San Dario Road 1 -05 Purchase of a water tank truck (see also Fire Protection). 1 -06 Overhaul of existing road grader. 1 1-07 Purchase or lease of a road - striper. 1 -08 Purchase of a tractor with weed cutter.

Town Council The Town Council is the duly elected body which is respons- ible for establishing ani carrying out policies, adopting 1 or amending laws, incurring financial obligations, and gen- erally making the decisions concerning public improvements 1 within the Town. The Town Council appoints the planning commission as well as all administrative officials and prescribes their duties and powers. The Town Council is not only responsible for carry- ing out town policies, ordinances and laws, but it is also responsible for the proper and legal handling of all town funds. 1 Because of its role as the policy and law making body, the 1 ultimate responsibility for implementing the comprehensive plan rests with the Town Council. It is not legally possible for the elected officials to delegate its policy making func- tion to any other agency. The Town Council may delegate duties but not the final responsibility. The decisions which the Town Council make will always be re- fleeted in the actions of the administrative officials. If the Town Council is divided, or is reticent to enforce any of the provisions of the development code, chances are the ad- ministrative.personnel will also become reticent to administer the code and eventually the plan and the code will grow into disrepute and do more harm than good. Experience will show that the influence of the plan will be as great as the Mayor 1 89 1. and Town Council wills it to be by their own actions. No, amendment to the code should be made unless the proposed change is first submitted to the Town Planning Commission for review. This same constraint should apply to any sub- stantial change in the Comprehensive Plan. In other words, ' after having adopted a Comprehensive Plan or an implementing measure such as a Development Code, the Town Council should submit any proposal for a change to the Planning Commission ' for its recommendations before adopting any change. The Council is not required to accept the recommendations of the Planning Commission, but it should at least refer the matter to the Planning Commission for its recommendations, then call a public hearing on the Planning Commission's recommendation before acting. Planning Commission Under Arizona Law, the Planning Commission is primarily an advisory body to the Town Council on matters dealing with physical development or change in the community. The law specifically sets forth the functions and duties of the Plan - ' ping Commission. The major responsibilities outlined within the law are: 1. To make approporiate surveys investigations, reports and . recommendations relating to planning and development with- ' in the community. 2. To prepare and recommend to the Town Council a Com- prehensive Plan for the physical development of the Town and ' to do the same with respect to amendments thereto. 3. To prepare a multi -year improvement program outlining ' necessary public improvements needed within the community, both now and in the future, and to suggest a program for financing i the needed improvements. 1 4. To prepare and recommend to the Town Council a ' Development Code which is in harmony with the Comprehensive Plan, and to conduct studies and make recommendations to the Council concerning any proposed amendment to the code. 5. To review and approve land subdivision plats, con— dominium projects, planned unit developments and other large scale development submitted by developers to make sure that 1 they conform to the Development Code. The Town is not required to accept the recommendations of the Planning Commission, but it should not amend the plan or the code without first requesting the Planning Commission to study and make its recommendations with respect thereto even though the Council may know what it intends to do. Planning and Zoning Administrator ' The Planning and Zoning Administrator has the responsibility 1 for the day to day administration of the development code and ordinances (zoning ordinances, subdivision regulations, other large scale developmen-s,building codes, etc.). In a manner of speaking, he is the policeman for the development regulations. It is he who is charged with the responsibility of enforcing the laws and policies as written. He should notify the Town Council of any violations of the code and then proceed to work with the Town's Attorney in restraining or avoiding such violation when instructed to do so by the Town 1 Council. However, he has no power to amend or alter the enacted laws and policies. He must administer the ordinances and laws as they appear in the ordinance book whether he agrees with them or not. 91 1 Board of Adjustment 1 Arizona's Law also provides for the creation of a Board of Adjustment. This body is a semi — judicial body appointed to 1 hear appeals from property owners concerning problems which arise as a result of a strict or literal enforcement of the zoning part of the code. In small communities the Town Council may serve as the Board t of Adjustment, but the decisions ;oust be in line with the specific powers and limitations placed upon the Board as ' follows: ' The Board of Adjustment shall have power: 1. To hear and decide appeals where it is alleged that there is error in any order, requirement, decision or deter— mination made by the Zoning Administrator in the enforcement of the Zoning Code. ' 2. To hear and decide special exceptions to the terms of the code upon which the Board is required to pass as ' specifically outlined within the code. 3. To authorize, upon appeal, such variance from the strict terms of the code as will not be contrary to the pub— lic interest. However, before any variance may be authorized ' it must be shown that: a. The variance will not substantially affect the comprehensive plan of the Town and that adherence to the strict letter of the code will cause difficulties and 1 hardships, the imposition of which, upon the petitioner, is unnecessary in order to carry out the general purpose of the plan. b. Special circumstances attach to the property covered by the application which do not generally apply 1 92 • 1 to the other property in the same zone. 1 c. That because of said special circumstances, property covered by application is deprived of privileges 1 possessed by other properties in the same zone; and that the granting of the variance is essential to the enjoy— ment of a substantial property right possessed by other property in the same zone. d. To hear and decide appeals for variances where it is alleged that there is an actual taking of private property for public use for street purposes over and above commensurate benefits to be derived therefrom in conforming to the right —of —way requirements for public 1 streets. In deciding such matters the Board of Adjust— ment must harmonize the interest of the land owner in his use and value of land and the benefits to the land owners by the construction of the public streets and may require developers to setback any and all buildings so as to conform with the major street plan until the matter has been resolved in a court of law. 1 The power of the Board of Adjustment to grant variances is 1 limited to questions dealing with area, such as reducing re— quired side or front yard'setbacks of buildings on lots which ' are too small to permit the development of a conforming struc— ture. Courts have construed the powers to be restrictive rather than liberal. A request for a variance should not be granted in cases involving a self imposed hardship or upon a pleading of ignorance of the law. Unless the Board finds ' that the variance is required in order for the owner to be able to enjoy the same rights as other owners of property in ' the same zone, the variance should not be granted. t be treated fairly, but should not be -rant— Th applicant should b y, ed a special privilege, not given to others in the same zone. In the past, Boards of Adjustments have made decisions which 93 1 1 have resulted in court trials in Arizona. Because court decisions often help clarify issues, all of the cases should 1 be reviewed by the Board of Adjustment prior to its rendering a decision on its first case. Plannin g Advisory Committee This consists of a selected group of citizens, who because of their knowledge and background, can render advice and ' council to the Town Council and Planning Commission in mat- ters relating to development within the Town. Terms of 1 their office are indefinite and they are expected to meet on call and render service as above described. There is no reason why the Town Council should not appoint the Plan- ning Commission from this group or it may appoint all members on the Planning Advisory Committee to the Town Planning Com- mission if it should choose to do so. 1 1 1 1 1 1 1 1 1 94 1 APPENDIX 1 PHYSICAL AND CULTURAL SETTING AND CHARACTERISTICS Basic to the development of a comprehensive plan is the recognition and consideration of the physical and cultural setting and characteristics of the area. They indicate problems and potentials for future development and improve- ments. A brief summary of the significant features about the Marana area has therefore been included in this part of 1 the comprehensive plan document. 1 Setting The Town of Marana is located in the north eastern part of Pima County near the junction of the Avra and Lower Santa Cruz valleys. The Santa Cruz River flows through the cen- tral part of the Town in a north - westerly direction. Inter- state Highway 10 and the Southern Pacific Railroad traverse 1 the eastern part of the Town. Following is a map which shows the community's setting graphically. 1 History 1 Marana was inhabited by the Hohokam Indians long before the coming of the Spanish conquistadores in the 18th century. In 1776 the Spaniards established a presidio at Tucson while the Marana area was dominated by the papago Indians who in turn 1 were dominated by the Apaches. In 1822 Spanish colonial rule changed to the Republic of Mex- ico. The area became part of the United States with the Gadsden purchase of 1854. 1 1 95 1 r 1 With the purchase of the territory in 1854, cattle ranching and mining operations began to appear around the Marana area. ' Likewise with the coming of the Southern Pacific Railroad Marana was given its first identification in the form of a ' flag stop. The name in Spanish means "a thicket" in recogni— tion of the dense brush along the Santa Cruz River banks. ' Yaqui Indians came in 1914 in order to escape persecution in north Mexico. In 1920 a well was drilled and an irrigation pumping plant ' was constructed which signaled the start of the cultivation of land on a meaningful basis. A man by the name of Post ' drilled a well which supplied irrigation water to several hundred acres of land. From this initial start came the formation of the Cortaro — Marana Irrigation District ' which now supplies most of the irrigation and domestic water to the residents living north of the Santa Cruz River, The limited erit ros of the 1 20's came to an end in the P P Y 9 early 1930's with the great depression. Most of the nearby mines closed down and the economy struggled to survive. S With the coming of World War II in 1941 the economy again accelerated. The Marana Air Base and its satellite fields ' gave employment to many people. Agriculture again flourished along with the mines. In 1947 the Trico Electric Cooperative was formed which brought electric power to the area. Impetus was further added to the economy with the outbreak of the Korean War. I.n the late 1950's the mechanical cotton picker was introduced. This allowed a handful of men to do what had previously re- 111 quired hundreds of unskilled migrant laborers to do. As a result the labor camps were closed and the population declined, 96 r but the agricultural economy increased when lettuce was 1 added to cotton as a major crop. The construction of a cement plant at Rillito further increased employment in the area, In 1961, construction of the freeway virtually destroyed ' Marana's business district until stores and other commercial establishments could be relocated. 1 During the 1970's the City of Tucson began to buy up land 1 in Avra Valley in order to be able to pump the ground water from Avra Valley to the Tucson Valley for domestic purposes. Approximately 12,000 acres of land was purchased for this purpose because state laws would not allow the separation of water from the land. ' In 1976 an effort was started by Marana residents to incor- ' porate the community in order to give the community pro- tection against the threatened encroachment of Tucson City interests, Incorporation took place in March of 1977 after 85% of the Town's registered voters presented a petition to do so to the Pima County Board of Supervisors. In 1978 the original 10 square mile town almost tripled in 1 size by annexing 18 sections of land to the town. Again in 1979 another section was added on the south east part of the town to serve as a location for industry. Also in 1979 the Town Council was successful in obtaining a federal grant to aid in the preparation of this Compre- hensive Plan. The foregoing is a very short account of the history of Marana 1 along with an account of some of the major economic and soc- ial forces which helped to form the town. ' Taken from a history of the Town entitled "Marana - Child of War and Water" as prepared and publish- ed in the Marana Messenger. 97 1 Topography ' The general topography of Marana dips slightly to the north— west at a grade of approximately one —half of one percent. The central part of the town is about 1980 feet in elevation as shown in geological survey maps. Generally the streets ' and roads constitute a grid system and correspond with the township, range and section lines of the general land survey. The following map also shows the general topography of Marana and surrounding area. Geology Geology of the area is important in understanding its soils, drainage and water supply. ' The boundary between the lower Santa Cruz Basin and the Tucson Basin is located up— stream about mile from the cement plant at Rillito. Not only is the Santa Cruz River confined at that point, but a subterranean dike also forces the ground water in the Tucson Basin to come close to the surface. Consequent— ly much of the water that is used to irrigate land in Marana is pumped onto the surface of the ground through wells that are located on the upper side of the dike. ' The dike is covered by soil to a depth of approximately 50' which indicates that Marana is covered by soil that has come from up— stream within or above Tucson Basin and from the Avra 1 Valley by way of the Brawley Wash and other lesser washes that begin in the surrounding mountains. The soil is mostly sandy loam, which has been washed in from ' higher up. It is deep and quite consistent throughout. Ex— cellent crops of cotton, lettuce and small grains, are grown wherever irrigation water can be obtained.

There are no natural stagnant ponds and no out— cropping of rocks although, the Avra Valley and the Tucson 1 Valley are surrounded by mountains. Drainage — Water The Santa Cruz River which flows through Marana originates 1 in southern Arizona and northern Mexico. Both heavy and infrequent rains produce enough runoff to cause the river 1 to flow. However, when cloudbursts occur on the watershed which extends into Mexico, the water drains along the river bed and terminates in seeps which are located several miles down — stream in Pinal County. Effluent from sewage treatment 1 plants located south of the Cortaro area is discharged into the river which also adds to the underground water supply. The effluent water must be treated to comply with Class C 1 Water Standards and as such does not polute the underground water supply to any greater extent than would irrigation or 1 flood water. 1 While floods are infrequent, several thousands of acre feet of water per year eventually find their way into the seeps, 1 northwest of Marana. This water might otherwise be used to grow crops in Marana, provided it could be retained in under— ground water acquifers. As it is, enough water flows down the 1 river from time to time to cause considerable damage as shown in the following photographs. 1 1 1 100 1 Climate 1 Daytime summer temperatures normally range from the high 80's to the low 100's. During winter time sub — freezing temperatures often occur at night, but daytime temperatures 1 normally reach the upper 60's and may even exceed 80 degrees. The average frost —free season extends from February to late 1 November and there may not even be a freeze during some years. Lettuce fields are usually planted in late December and thinned during late January for the spring crop, then planted again in August for the fall crop. 1 The climate in the winter time is attractive to many people because the air is generally dry and clear. Snow rarely 1 stays on the ground for more than an hour, even when it does snow, which is rare. Summertime temperatures are un— 1 comfortably hot in the afternoons which have motivated vir— tually all home owners to install either refrigerated air conditioning or evaporative coolers in their dwellings and business buildings, but the evenings are usually fairly comfortable. Drainage — Air 1 The air does not blow in one prevailing direction, but tends 1 to follow a pattern common in the valleys of southern Arizona, i.e. downvailey (to the northwest) in the mornings, and up— valley (to the southeast) in the afternoons, with seasonal prevailing winds from the west. Water Resources 1 Like most communities in Arizona, water supply has been a critical factor in the town's growth. The only source of irrigation water comes from wells, most of which have been drilled and maintained by the Cortaro Water Users Association/ 101 1 1 Cortaro - Marana Irrigation District. Some of the water is used for culinary purposes. Wells have been drilled in many places in the Marana — Cortaro 1 area. The location of most of the wells have been shown on the following map of the area. In the past, domestic water for Marana has been obtained from two private firms and from the Cortaro Water Users As- 1 sociation. The water is reasonably soft and is satisfactory for most domestic and culinary purposes. However, a small 1 northeast corner of the town is underlain with acquifers which contain nitrates that are above the maximum allowable 1 limits for culinary water. One of the domestic wells owned by the Cortaro Water Users Association which supplies water 1 for 18 homes contains excessive quantities of nitrates. The Cortaro Water Users Association has 17 wells in the Marana area for irrigation use that yield from 2,000 to 3,000 gallons per minute and 3 wells for domestic use. Wells 1 that have been drilled in the Marana area have not exceeded 1,000' in depth. Water from wells that have been drilled in 1 the area lying west of Marana have indicated that the quality has decreased in wells that have been drilled to depths ex— ceeding 1,500 feet. The depths of most of the wells in the 1 Marana area, ranges from 500 to 1,000 feet. Static water levels have varied from 325 to 335 feet in depth depending upon the amount of precipitation. 1 The Cortaro Water Users Association supplied 30,622,400 gal— lons of domestic water to 190 customers in 1978, which is 1 an average of 450 gallons per customer per day. Most of the remaining 200 dwellings are supplied from central wells which have been drilled in connection with subdivision deve— lopments 1 or from individual wells which have been drilled in connection with the development of farmsteads. 1 102 1 .......1■1...... ■■■•■•• 1 I , 4t1 0 I .

Of this amount, approximately 810 acres have 1 been developed for residential, commercial, industrial, park, schools, streets and other urban type purposes. t It can be seen from the following figures that the Town contains a large amount of agricultural or range land. II Type of Land Use Acres % Normal % 1. Range Land 8,440 II 2. Cultivated Land 9,051 3. Developed Land 810 100 1 Residential Land 195 24.4 42 Commercial Land 19 2.3 4 I Industrial Land 47 5.8 12 Schools, Churches, parks 77 9.5 12 Streets & highways 472 58.0 30 il — TOTAL 18,300 100.0 100.0 As indicated above, 810 acres of the total land area in I Marana have been developed into some type of urban use or approximately 4.4% of the area. Marana has a population of approximately 1,600 people living within the Town limits which amount to .50 acres of developed 1 land per capita. This is high compared to most other com— munities primarily because of the relatively large amount of I land that has been devoted to streets. I It can be expected that the amount of land, per capita, which is devoted to urban uses will decrease as the population in— creases. For example, surveys have shown that the amount of 1 I 104 1 developed land per capita in over 200 cities, ranging in population from 8,000 to 12,000 people averages .14 acres per capita, a difference of approximately 32 times. Also, as indicated above, the proportion of developed land that is used for residential purposes in the normal Amer— ican city is 42 %, while the proportion of such land that is used for streets averages 30%. The percentages vary somewhat for larger cities that con— 1 twin numerous multiple dwellings and high rise apartments. Economic Base 1 Agriculture is the primary element in Marana's economic base. Over 8,000 acres have been brought under cultivation and most of the remaining land is pastured by livestock. Other significant elements in the economy include, the ginning and baling of cotton and the packing of lettuce, along with i the harvesting of grains. Other significant elements also contribute to the economy even though the location of em— 1 ployment is not in the Town. These elements include mining, working in Tucson Valley, retail trade and services and the Rillito Cement Plant. Population In view of the fact that Marana was incorporated only two years ago, population statistics for the Town are very meager. Estimates and surveys indicate that the Town contained approx— imately 1,200 people in 1970 and that this number had in— creased to approximately 1,500 in 1975 and again approximately 1,600 people in 1978. Forecast 1 A compilation and analysis of the factors which usually have 1 105 1 1 an effect on population indicates that the Town will con— tinue to increase in population. Conservatively, the Town 1 will reach a population of nearly 4,000 people by the year 2000. On the other hand, if industry settles in the Town 1 in record numbers population could increase to 16,000 by the year 2000. Beginning in 1947 the birth rate in the nation increased significantly. It then continued to increase gradually until 1959, then started to decline. By 1965 the national birth rate had declined to its lowest point in recorded ' history. It continued to decline at a slow downward rate until 1973 when it began to climb again very slowly up to the present time. But it is currently less then 80% as much as it was in 1958. ' In view of the fact that the national birth rate began to decrease in 1959 and continued on a downward course for 13 years, rate of family formations will also decrease for about the same length of time beginning in 1982. This movement will likely affect every community in the country including Marana. The chances are that the rate of the ' construction of dwellings will follow the downward trend in the number of family formations unless a significant amount of industrial development takes place in the Marana area which ' will provide employment. To a large extent, population will increase or may even decrease depending upon the amount of 1 industrial development that takes place. ' While it is impossible to forecast population accurately over a long period of time, it is necessary, nevertheless, to prepare plans with a given number of people in mind. If population increases faster than expected it will be neces— sary to speed up the rate of the installation of services. ' Conversely, if it occurs at a slower rate it will then not be necessary to construct facilities as fast as expected. ' 106 1 A population of 5,500 people has been selected as the likely 1 number of people that will be living in Marana in the year 2000. However, much will depend upon the amount of job 1 creating industry that will be generated between the pre— sent time and the year 2000. Following is a chart which shows the estimated range of pop— 111 ulation for Marana, compared to North Avra Valley, North— west Greater Tucson area and Eastern Pima County. 1 1 1 1 1 1 1 1 1 1 1 1 1 107 1 1 ,.

The four causal elements are: (1) natural resources; including land and water as well as mineral and biological resources and climate; (2) people; including their number, abilities, and attitudes as well as other characteristics; (3) transportation; including both inter —urban and intra —urban facilities; and (4) institutions; including tax arrangements as well as other laws and govern— 1 ment practices for those governments with jurisdictions over the community. 1 These major casual factors in turn affect the growth in the communityfs population, the nature of its economic development, and the use of land and other natural resources within the community, The initial results of the action of the four major causes to a certain extent then become causal factors themselves and in turn yield additional results. The exist— ing population attracts a larger population, which in turn provides a labor force, which in turn attracts more economic development and more sources of employment, which in turn attracts more population, and so it goes. Just the opposite can also be true. Withdrawal of natural resources such as water or land from use may force an exodus ' of population, which in turn discourages economic develop— ment, which in turn forces more people to leave, and so on. 1 In either case, growth or decline, the size of the population, the diversity, self sufficiency, and prosperity of the local economy, and the types, intensity, and configuration of land use within the community will be the results of what has gone before and the effects of the four major causal factors listed above. 1 109 1 1 In Marana, the most important natural resources that will have the greatest impact on the community's economic deve- 1 lopment are: (1) climate; (2) level, irrigable, and fer— tile land; and (3) sufficient supplies of groundwater at a 1 cost that permits use in irrigated agriculture and of a quality that permits appropriate domestic use. Natural resources in nearby areas that have had and will have an impact on the development of the Marana community, in ad— dition to agriculture, include copper mineral resources in the Silver Bell Mountains to the west and limestone deposits in the Twin Peaks area to the south. Transportation facilities that are of critical importance 1 in the economic development of Marana are: (1) the main line of the Southern Pacific Railroad; (2) Interstate 10; ' (3) airports on Avra Valley Road at San Dario Road and at the Evergreen Air Center (Marana Air Park) to the northwest ' of the community; (4) major natural gas and petroleum pipe— lines that traverse the Town roughly parallel to the rail— road and the interstate highway; (5) a major electrical transmission line that traverses the southwest portion of the Town; (6) the irrigation canals that bring irrigation 1 water from the Cortaro area and distribute it throughout the community; and (7) the network of secondary roads within the Marana — Avra Valley area, especially the Trico — Marana Road connecting the Town with communities to the west, Sanders ' and San Dario Roads, linking the Town with communities to the south, and the Avra Valley Road, connecting the Town with communities to the west and east. In addition, sometime in ' the 1980'x the main canal of the Central Arizona Project taking Colorado River water to the Tucson urban area should 1 pass through or very close to the Town of Marana and could become an important factor in the community's economic deve— lopment either through a direct connection to the aqueduct or by an increase in the amount of available groundwater. 1 110 1 The number of people living within the Town of Marana pro— vides a relatively small base for economic development at present, but the much larger number residing in the northern part of the Avra Valley and other nearby communities pro— vides a much larger base, both as a labor force and as a ' potential consumer market, The extent to which this nearby population becomes either a labor force or a significant 1 consumer market will have a major bearing on the future economic development of Marana, particularly if Marana becomes the chief commercial and residential nucleus. The high level of skill of the local population already pro— vides a significant resource for future economic growth, but the tendency of the local population to turn toward Tucson , in employment and buying could prove a detriment to local economic development unless the Town Council and the citizens ' are successful in attracting additional retail outlets into the commercial nucleus. Local laws and other institutional arrangements will have a significant impact on future economic development in Marana. At present, the Town has no property tax of its own, although local property owners must still pay state, county, and school 1 district property taxes. A lower tax rate than nearby com— munities of Pima and Pinal counties could serve to attract ' manufacturing and other job — providing activities to the community as well as help to preserve the existing agricultural and commercial base of the local economy. The comparative tax rate will be as much a function of local school district tax rates as of the Town of Marana. ' The quality of the local school system is also likely to be ' important in the future economic development of the Marana community. A school system of high quality will tend to attract a population with higher personal incomes, thereby adding significantly to the local consumer market and encour— 111 11 aging greater local commercial development, A school sys— tem of high quality operated at a reasonable cost can also be a signficant item in the attraction of manufacturing and other job — providing activities, thereby aiding in the industr— ial development of the community. ' At present, the Town of Marana has a local sales tax on retail and other sales made within the Town. Although the ' presence of any such sales tax is not as important in local commercial development as the overall size and income of the local consumer market, the imposition of the additional ' sales taxes to those already levied by the State of Arizona is likely to seriously hinder further commercial development to ' serve the local market and could in fact, cause an actual decrease in existing local commercial activity. The decrease ' would be caused by a flight of local purchasing dollars to the major retail centers now in existence and developing in the northwestern part of the Tucson urban area outside of the City of Tucson and therefore not subject to the City of Tuc— son's retail sales tax. A substantial share of local con— sumer spending is already directed to retail establishments in the northwest part of the Tucson urban area, and this con — dition is likely to persist until the commercial sector of the Marana community provides goods and services in greater ' diversity at prices comparable to those found in the Tucson urban area. Another major institutional factor that will have a direct effect on the growth and development of the Marana community ' is the pattern of land ownership. At present, much of the ' 112 11 communit y developable develo able land is in the hands of a small number of large landowners, including the State of Arizona. 11 Until a greater diversity of land ownership iS achieved, the conversion of land from its present agricultural uses to urban uses is likely to be slow. This is likely to have a i dampening effect on population and commercial growth within the Town of Marana, but it will also act to preserve the 1 present agricultural employment base of the local economy. Again, much will depend upon the success which the Town Council and the people have in convincing developers to provide decent housing in :the areas designated for urban development, rather than in a scattered manner and also upon the success which the Town Council has on convincing the County Assessor to keep assessed valuation on land within ' the designated areas up —to —date with market value annually, otherwise property owners can be expected to hold onto ' their land for speculative purposes. The present economy of the Marana community and its environs is an obvious and direct result of the major causal factors that have created it. Agriculture has been for more than 50 years and still is the mainstay of the local economy. Ap— proximately 20 large farming and ranching firms form the 1 backbone of the Marna — Avra Valley economy, producing cotton, grains, pecans, and lettuce as well as cattle, swine, poultry, 1 eggs, and milk. A substantial portion of the community's manufacturing activity is also related to farming with four major cotton ginning firms operating in the immediate area The community's wholesale trade sector is also heavily orient— ed towards farming, with three firms providing pesticides 1 and fertilizers to local growers and two major lettuce packing and shipping operations located in the area, one at Rillito 1 and one at Red Rock. The mineral industries are also important to the economy of the Marana area, although none are located within the Town of 113 1 1 Marano. The copper mines in the Silver Bell Mountains have ' been a source of jobs and economic activity in the area for more than a century, while the limestone deposits near the north end of the Tucson Mountains have been providing the raw ' material for cement manufacture at Rillito for almost three decades. Employment at the Silver Bell operations of Asarco, 1 Inc. and at the Rillito operations of the Arizona Portland Cement Company is a significant source of personal income for 1 residents of the Town of Marana. Manufacturing, other than that directly relating to agricul— tural, has been severely limited in the Marana area, although one small electronics plant is now operating in the Avra ' Valley just south of the Town limits. Tourism is also limited despite the heavy volume of travel on Interstate 10 1 through the community and the large and growing volume of visitation at tourist attractions in the Tucson Mountains 1 south of the community. By mid -1979, only two service sta— tions, two fast food operations, one convenience store, and one bar were providing any significant amount of service to the more than 19,000 vehicles per day passing through the community on the Interstate highway. Only one small p roduce ' stand appeared to be deriving any business at all from the thousands of visitors to the Saguaro National Monument, ' Arizona — Sonora Desert Museum, and Old Tucson tourist at— tractions in the Tucson Mountains to the south of the Town. One other activity of a mixed nature that is of significance ' to the economy of the Marana community is the operation of the Evergreen Air Center (Marana Air Park) just northwest of the Town of Marana. The Center provides aircraft servicing and training facilities to a variety of private and govern— mental clients and in doing so provides a significant amount 1 of employmeri t to residents of the Town of Marana. Other air — oriented firms in the Marana area are linked closely with ' agricultural, providing crop dusting services and transportation ' 114 for farm operators and others. Most of the negative effects of this activity could be 1 naturalized by the construction and operation of an excel— lent dining facility in Marana's commercial nucleus. ' Virtually all of the other commercial activities in the 1 Marana area serve to provide goods and services to the local industrial and consumer population. Water is provided by the Cortaro Water Users Association, a cooperative with quasi — municipality status, and several small privately owned companies. Electric power is provided by the Tucson Electric Power Company and the Trico Electric Cooperative. Natural Gas is provided by the Southwest Gas Company, and , telephone service is provided by the Mountain Bell Telephone Company. ' Eight small grocery stores make up the retail grocery sector of the Marana — Avra Valley area, with four of the eight located within the Town of Marana. Most of the other retail trade and service businesses in the Town and its immediate environs are oriented toward automotive repair and service or toward personal services. The area has one bank, located 1 in the Town of Marana, and two insurance agencies plus sev— eral real estate agencies. ' Future economic development of the Marana community is likely to come in several areas. At best, agriculture will remain stable, although the potential for further crop diversifica— tion is present and could have a significant impact on manu— facturing, wholesaling, and farm service operations in the community. Mineral industry activity in the Marana — Avra Valley area is also likely to remain stable as long as the ' general economy tends to grow. Moreover, further metallic mining development on the western edge of the Avra Valley ' 115 1 may occur in;the 1980ts. Such development, however, may ' simply replace existing operations with no net increase in mineral industry employment in the area. Adverse economic conditions in the nation could, however, have an. adverse ' impact on copper mining in,the area, and any substantial decrease in construction in the Tucson area or southern Arizona could decrease activity at the Rillito cement plant. Expansion in manufacturing and the tourist — serving industries provide the best potential for future economic development in the Marana community. Electronics manufacturing and other ' high technology industries, including aircraft manufacturing, have already begun to expand rapidly in the Tucson urban ' area, and it is reasonable to expect that with the proper promotional effort, such expansion could be attracted, at least in some measure, to the Marana area. A large stream of travelers already pass through the Marana area, both on Interstate 10 and on the San Dario Road — Avra Valley Road circuit to tourist attractions in the Tucson Mountains. Deve— lopment of this potential simply awaits the efforts and fin— ancial resources of one or more enlightened entrepreneurs. 1 Development of the retail trade and services sector and the finance, insurance, and real estate sectors of the Marana economy will be dependent upon the growth of the local population. The growth of the local population, in turn, will be dependent upon the availability of local sources of employment and the extent to which the Marana community becomes a suburb for those employed in the Tucson urban area. Those two conditions can be influenced heavily by what the people of Marana and their local government do to make the community attractive for both businesses and residents. 1 At the present time there are several small urban nuclei in the area lying north and west of the Rillito narrows but no 1 116 1 one dominant urban center has emerged as yet. Marana is the largest of the nuclei and is situated in an advantageous position. It could be converted into the dominant center 1 by the development of a compact retail trade and service center. The addition of one or more motels plus a fine 1 restaurant near the Trico — Marana interchange would likely be sufficient to initiate such a trend. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 117 1
