URBAN RECREATION FACILITIES -- NORTHEAST QUADRANT . . . . . . . . 92 - v - 1992 UPDATE -- NORTHEAST QUADRANT ANNEXATION MASTER PLAN PUEBLO, COLORADO I. INTRODUCTION A. PURPOSE The Northeast Quadrant Annexation Master Plan is prepared in response to the Municipal Annexation Act of 1965 (Section 31- 12- 105[l][e], CRS [1988 Cum. Supp.]) as amended by Senate Bill 45 (1987). Compliance of this act requires that prior to completion of any annexation, a municipality shall have in place a plan that generally describes proposed public facilities, utilities, and land uses within a three —mile limit from current City boundaries. Section 12 -5 of the Charter of Pueblo authorizes the preparation of a master plan for the physical development of the City. The Department of Planning and Development is charged with the responsibility of conducting such long —range planning activities for the City of Pueblo. The goal of long —range master planning is to provide a framework which will guide development in a consistent manner. Individual annexation and development decisions may then be made according to criteria that best suits the overall goals of the City. The Northeast Quadrant Annexation Master Plan addresses potential growth from recent developments at the Pueblo Memorial Airport Industrial Park (AIP) and proposed development adjacent to the University of Southern Colorado. The AIP, owned by but not located within the Corporate limits of the City of Pueblo, is rapidly developing as the largest industrial park in Southern Colorado. Intensive building at the AIP began in 1984 when Unisys constructed a new plant. It has since grown with the construction of new facilities by Target (Dayton Hudson Corporation), Pryor — Giggy, Atlas Pacific, Kurt Manufacturing, Trane Corporation, B. F. Goodrich Company, PCL Corporation, McDonnell Douglas Corporation, and Kaiser Corporation. The employment generated by these industries has fueled interest in residential development within the Northeast Quadrant. In addition, a new municipal golf course (WalkingStick) adjacent to the west side of the University of Southern Colorado officially opened in July, 1991. The development of associated commercial and residential land surrounding the golf course is under negotiation. The Northeast Quadrant Annexation Master Plan establishes specific guidelines and recommends policies which will ensure that annexation and development is consistent and compatible with existing land uses, land use and transportation policies, and with State annexation statutes. B. OBJECTIVE This annexation master plan will serve as the official "Three —Mile Annexation Plan" for the Northeast Quadrant. It does not supersede the 1980 Pueblo Regional Comprehensive Development Plan except insofar as it shall be used to identify proposed land uses in that area defined as the "proposed urban extension area" within the Northeast Quadrant. It is designed to be a framework for development, with sufficient flexibility to be changed as conditions warrant. The goals of the Northeast Quadrant Annexation Master Plan are to: GOAL 1 : Establish land use and annexation policies which will guide development within the Northeast Quadrant. These policies will provide a standard approach for future annexations and will supplement City zoning and subdivision regulations. GOAL 2 : Comply with State annexation laws, Pueblo Board of Water Works policies, and U. S. Government Federal Aviation Administration (FAA) airport regulations and aircraft noise recommendations. GOAL 3 : Identify proposed public facilities, utilities, and land uses within the Northeast Quadrant. GOAL 4 : Provide an inventory of the planning area in relation to the natural environment, the infrastructure, and available public facilities. C. ASSUMPTIONS For the purpose of this plan, the following assumptions are made: 1. Development at the AIP will continue at its existing rate. 2. There will be continued pressure to develop the land adjoining the University of Southern Colorado. 3. There will be a need for additional roadway access to the AIP. 4. There will be a need to protect the AIP from incompatible development. D. LOCATION The Northeast Quadrant Annexation Master Plan area contains approximately 50 square miles and encompasses an area which extends three miles from the existing City limit line adjoining the Northeast portion of Pueblo, Colorado. The Northeast Quadrant Annexation Master Plan study area is that area bound on the south by Highway 50 —C (State Highway 96); on the east by State Highway 231 (36th Lane extended north); on the north by the KCSJ Radio Tower on Baculite Mesa; and on the west by Interstate 25 (See Map I). This study area has been divided into an Urban (proposed urban extension area) and a Rural category. The Urban /Rural Demarcation Line identifies the boundary beyond which urbanization is not anticipated to occur within a 12 —month period following the adoption of this plan. The term "proposed urban extension area" indicates that area which is considered to be the most probable for annexation based on the ability to extend municipal service into the area (See Map II). — 2 — - 3 - un w a aanrial smalls aautu nua nnau�Suu1110AN �uasaue4 + v uutaa�la'annau aunuiva anuaak ..

ANNEXATION REQUIREMENTS PREFACE This plan is designed to conform with the Municipal Annexation Act of 1965 (Part I of Article 12 of Title 31, CRS) amended by Senate Bill 45 (1987). This Act requires a municipality to develop an annexation master plan describing proposed public facilities, utilities, and land uses within a three -mile limit from current City boundaries. A. COLORADO ANNEXATION REQUIREMENTS Senate Bill 45 was passed in the 1987 Session of the Colorado General Assembly. The following requirements apply to all municipal annexations requested after May 28, 1987. 1. Development Eligibility (CRS Title 31 -12 -104) The perimeter of the area proposed for annexation must have no less than one -sixth contiguity with the annexing municipality. Contiguity may be established by the annexation of one, or more, parcel in a series, completed simultaneously, and considered together for the purposes of public hearing requirements. Contiguity is not affected by the existence of a platted street or alley, a public or private right -of -way, a public or private transportation right -of -way, and public lands whether owned by the State, the United States, or an agency thereof (except County owned open space), or a lake, reservoir, stream, or other natural or artificial waterway between the annexing municipality and the land proposed to be annexed. Municipality boundaries shall not be extended more than three miles in any direction from any point of such municipal boundary in any one year. Such three -mile limit may be exceeded if it would have the effect of dividing a parcel of property held in identical ownership, provided that at least 50 percent of the property is within the three -mile limit. Such three -mile limit may also be exceeded for the annexation of an enterprise zone. The area within the Northeast Quadrant which is within an enterprise zone is depicted in Map III. 2. Annexation Master Plan (CRS Title 31 -12- 105[11 -[el) Prior to completion of any annexation within the three -mile area, the municipality shall have a plan in place for that area which describes the proposed location, character, and extent of streets, subways, bridges, waterways, waterfronts, parkways, playgrounds, squares, parks, aviation fields, other public ways, grounds, open spaces, public utilities, and terminals for water, light, sanitation, and transportation. Power to be provided by the municipality and the proposed land uses for the area shall be addressed. Such plan shall be updated at least once annually. - 5 - oil ttt lttllttttlt Itttt lttttll tt tl ltt It llltt tt t111 Cri{l.�l / �1 IIIIItt Il It111111111t Illlltt�mit11t PQ I Z� �+ . j v, hNi 111 t 1 l _ r.s,t'� -"tom, I �m'e�► r _ ..1 x ._ .'.._ _ MAP— .12111212129121 A 1�1 z 0 rA BBL H a P4 1=+ W u City of Pueblo Department of Planning & Development MAP: NORTHEAST QUADRANT ANNEXATION MASTER PLAN III 6 - 3. Annexation Impact Report (CRS Title 31 -12- 108.5) The municipality shall prepare an impact report concerning any proposed annexation at least twenty five days before the date of the hearing. Such report shall not be required for annexations of ten acres or fewer in total area or when the municipality and the Board of County Commissioners governing the area proposed to be annexed agree that the report may be waived. Such report shall include as a minimum a map or maps of the municipality and adjacent territory to show the following information: a. the present and proposed boundaries of the municipality in the vicinity of the proposed annexation; b. the present streets, major trunk water mains, sewer interceptors and outfalls, other utility lines and ditches, and the proposed extension of such streets and utility lines in the vicinity of the proposed annexation; c. the existing and proposed land use patterns in the areas to be annexed; d. a copy of any draft or final pre- annexation agreement, if available; e. a statement setting forth the plans of the municipality for extending to or otherwise providing for, within the area to be annexed, municipal services performed by or on behalf of the municipality at the time of annexation; f, a statement setting forth the method under which the municipality plans to finance the extension of the municipal services into the area to be annexed; g. a statement identifying existing districts within the area to be annexed; and h. a statement on the effect of annexation upon local public school district systems including the estimated number of students generated and the capital construction required to educate such students. B. CITY ANNEXATION REQUIREMENTS This section describes general guidelines to be followed by those persons (hereinafter referred to as the Petitioner) wishing to petition the City of Pueblo for annexation. The minimum requirements the Petitioner must meet are: o The proposed annexation is a logical extension of the City's boundary and municipal services; and o The Petitioner shall submit a Property Master Plan (PMP) to City Council for adoption. The PMP must comply with the policies of the Pueblo Regional Comprehensive Plan and the Northeast Quadrant Annexation Master Plan presently existing and as same may hereafter be amended. The Petitioner shall provide a PMP to City representatives for review. Adequate time for discussion, debate, and revision should be allowed. The PMP shall consist of the following: - 7 - 1. Development Plan The Development Plan shall be prepared by the Petitioner in consultation with the City's Subdivision Review Committee and Department of Planning and Development. This plan must be in accordance with the requirements of Title 12- 4 -6(A) of the 1971 Code of Ordinances of the City of Pueblo and as same may be subsequently amended. A phasing plan outlining the anticipated order of development projects for the Property shall be included in the Development Plan. 2. Drainage Plan The Drainage Plan submitted by the Petitioner shall be in accordance with the Pueblo Storm Drainage Criteria Manual then in effect. This Plan must be certified by a licensed Professional Engineer competent in the field of surface water drainage engineering and registered in the State of Colorado. The Drainage Plan shall address on -site and off -site surface water drainage, as well as the effects of the proposed development upon downstream properties and existing drainage facilities. Associated impacts identified in the Drainage Plan will be mitigated through surface water drainage improvements financed by the Petitioner. Stormwater detention facilities, designed and constructed in accordance with the Manual may be used to mitigate the increased runoff due to development. The Drainage Plan shall include a phasing plan outlining the order of necessary drainage improvements. 3. Sanitary Sewer Report The Petitioner shall prepare a Sanitary Sewer Report in accordance with criteria specified by the Director of Public Works. This Report shall be supported by studies and reports prepared by a licensed Professional Engineer. The Report shall address the needs of the entire sewer drainage basin. This basin will be designated by the Director of Public Works. The existing wastewater system and the impact on that system by the proposed development shall also be addressed. Any impacts by the proposed development shall be mitigated by the Petitioner through sanitary sewer improvements financed by the Petitioner. The Sanitary Sewer Report shall provide a phasing plan for anticipated improvements. In some cases, the Petitioner will be required to install oversized sanitary sewers in the PMP area. These oversized sanitary sewers would serve future development outside the PMP area, but within the sewer drainage basin. A Sewer Participation Cost Recovery Agreement may be entered into between the Petitioner and the City. The Petitioner may then be reimbursed for the oversize cost by a newly benefitted Property owner when any part of the benefitted Property within an approved subdivision is connected, directly or indirectly, to such oversized sewers located within the PMP area. If the Petitioner constructs sewer improvements downstream from the master plan area which will serve future development outside the master plan area, the Sewer Participation Cost Recovery Agreement shall include provisions so that the Petitioner may be reimbursed for a pro -rata share of the costs of construction of such downstream improvements, plus interest, by the benefitted Property owner when any part of the benefitted Property is connected, directly or indirectly, to such sewers. The Sewer Participation Cost Recovery Agreement shall be in conformity with the City's then existing ordinances and shall be approved by City Council. a. Sanitary Sewer Report Criteria The following criteria will provide guidelines for the planning and design of sanitary sewers. These guidelines shall include planning criteria and minimum or maximum controls of sewer design and construction. However, in unusual circumstances or where special conditions dictate, certain deviations from the standard criteria may be directed or approved by the Director of Public Works. All improvements to the sanitary sewer system shall be planned and designed to provide adequate service as specified by the following: (1) Acreages for separate land uses, i.e., single — family, multifamily, commercial, and industrial, shall be established based upon the Development Plan.

IMGRID Analysis The IMGRID (Improved Grid) Analysis was prepared in 1977 and determines, by computer analysis and mapping, the geographic location of natural hazards and resources in Pueblo County, Colorado. The analysis is designed to address the concerns described in Footnote 37 of Senate Bill 468 (1975) as Pertinent Matters and includes: - 15 - a. Floodplain Hazards; b. Wildfire Hazards; c. Geologic Hazards (1) Unstable Slopes (2) Mud Flows /Debris Fans (3) Expansive Soils and Rocks (4) Ground Subsidence (5) Seismic Effects (6) Radioactivity (7) Rockfalls (8) Landslides (9) Avalanches d. Mineral Resource Areas 2. Section 208 Water Quality Program, Pueblo, Colorado Water Quality Management Planning is required under Section 208 of the Federal Clean Water Act, Public Law 92 -800. The purpose of this Act is to preserve and enhance the Nation's water systems. The Pueblo 208 Water Quality Program was first implemented in 1977 with subsequent updates in 1981, 1984, and 1987 by the Pueblo Area Council of Governments (PACOG). The Pueblo Water Quality Management Plan is now comprised of six (6) volumes: Volume I: 208 Stream Segment Analysis, June, 1977; Volume II: 208 Point Source, Non -Point Source, Institution /Management Subplans, June, 1977; Volume III: 208 Final Plan and Implementation Schedule, July, 1977; Volume IV: 208 Plan Update, 1981 Volume V: 208 Plan Update, 1984; and Volume VI: 2 Plan Update, 1987. These plans analyze the main water sources, both ground and surface, for Pueblo County. Wastewater facilities are examined; point and non -point pollution sources are assessed; methodology and results of water tests are documented; and stream segments are analyzed. Surface watercourses included are: a. the Arkansas River -- Segments A, B, and C; b. the Fountain Creek; c. the St. Charles River -- Segments A, B, and C; d. Greenhorn Creek -- Segments A and B; e. Six -Mile Creek; and f. the Huerfano River. The 1987 208 Plan Update reviews point source pollution, sludge production, and wastewater disposal by the City and outlying sanitary districts. - 16 - 3. General and Engineering Geology of the Northern Part of Pueblo, Colorado This Geological Survey Bulletin 1262 was prepared by Glenn R. Scott in 1969. This document locates bedrock formations and surficial deposits for Pueblo County. The bulletin also identifies general characteristics and engineering concerns for each geologic member. B. LAND USE AND INFRASTRUCTURE 1. Pueblo Regional Comprehensive Development Plan The Pueblo Regional Comprehensive Development Plan was prepared by the Pueblo Regional Planning Commission and adopted by the City of Pueblo and Pueblo County in 1980. The purpose of this document is to prepare for necessary and desirable growth through the development of a master plan for physical development. The plan includes eight major parts, or elements, which address concerns associated with physical development in the region. The eight elements are Land Use, Housing, Public Facilities, Environmental Quality, Land Conservation, Parks and Recreation, Transportation, and Downtown Pueblo. The overall concept that guides the Plan's recommendations is the desire that the Pueblo region grow in a way that will not detract from the quality of life of its residents. The Plan's goals, policies, and land use recommendations consistently attempt to reflect the community's desire to be prepared to accept growth which is deemed to be necessary and desirable for all residents. 2. City of Pueblo Urban Parks and Recreation Recovery Action Program The City of Pueblo Urban Parks and Recreation Recovery Action Program ( UPARR) was prepared by the Pueblo Regional Planning Commission and adopted by City Council in 1981. The UPARR assessed the physical inventory, the rehabilitative capability, and the concerns of the City of Pueblo Parks and Recreation Department. This federally funded program was designed to help physically and economically distressed urban areas improve recreational opportunities. The conclusion of this report states that Pueblo's physical parks system is evidence of a firm foundation for providing the open spaces and services needed and requested by its population. Recent emphasis to provide parks on the neighborhood level has had positive results, but future planning should consider more strongly the need for quality design, construction, rehabilitation, renovation, operations, maintenance, and the need for the development of additional City -wide facilities. The UPARR report is presently being updated to fulfill Federal eligibility requirements for possible funding of future projects. 3. Airport Subdivision Sketch Plan The City of Pueblo in 1986 prepared a sketch Airport property. The purpose was to enhance Airport and AIP. The sketch plan (See Map IV) is the Pueblo County's subdivision process.

Pueblo Memorial Airport Master Plan The Pueblo Airport Master Plan was prepared in 1975 to provide an objective analysis of the facilities and capabilities of Pueblo Memorial Airport. It presents a detailed, yet flexible, plan for the future needs of the airport. Based upon the available data, this plan was designed to furnish reasonable recommendations for the aviation needs of 1975 and thereafter for the Pueblo area. Recommendations and alternatives for meeting aviation demands were presented. These provided for short —range (5— year), intermediate range (10— year), and long range (20 —year) development. It should be understood that this document, although detailed, is for use as a general guideline for the continued development of the Pueblo Memorial Airport and AIP areas. The development recommendations set forth in this analysis provide guidance for long —range airport needs of the Pueblo area. The Airport Master Plan is currently being updated. 6. Airport Noise Compatibility Prooram Federal Aviation Regulation (FAR) Part 150 implements portions of Title I of the Aviation Safety and Noise Abatement Act of 1979. It establishes a single system for the measurement of airport (and background) noise, a single system for determining the exposure of individuals to airport noise, and a standardized airport noise compatibility planning program. The planning program includes: (1) a provision for the development and submission to the FAA of Noise Exposure Maps and Noise Compatibility Programs by Airport operations; (2) standard noise units, methods, and analytical techniques for use in airport noise assessments; (3) identification of land uses which are normally considered compatible (or non — compatible) with various levels of noise around airports; and (4) procedures and criteria for FAA approval or disapproval of noise compatibility programs by the administrator. The program includes consideration of alternative noise control that might be employed, as well as appropriate land use planning strategies. The goal of the overall program is for the airport proprietor, in consultation with State /local planners, local aviation groups, and interested citizens, to develop a balanced and cost — effective program to minimize and /or mitigate the airport's noise impact on local communities. This study is currently being prepared. — 19 — 7. Pueblo Board of Water Works Water Distribution Plan In 1979, Black and Veatch, consulting engineers, prepared a water distribution system study for the Pueblo Board of Water Works. The report provides a master plan for improvement and construction by the Board in its continuing program of water distribution. The purpose is to determine the adequacy of the Pueblo Water Distribution System in satisfying present and future water needs through the Year 1985. The report provides a general guideline for projections made through the Year 2000 and contains area development studies to determine present and estimated future population distribution within the service area. Estimates of water demands and predicted distribution demands on the system are also analyzed. In 1976, the Board of Water Works published an informational booklet, Pueblo's Water System which describes the sources of water supply and follows the water through the treatment system and to the tap. 8. Sanitary Sewerage and Wastewater Treatment Facilities An engineering report was prepared in 1971 by Sellards and Grigg (S &G), Inc. The report presented a study of the City's sanitary sewage and wastewater treatment facilities. Proposals for additions and corrections to the existing system were set forth in order to plan for an efficient treatment system for the present and future needs of the City. The scope of the work within the report included the following: a. development of a long —range master plan for the sewerage and establishment of a service area boundary; and b. analysis of the existing wastewater treatment plant (WWTP) and recommended improvements to correct deficiencies and to provide capacity for future needs. Since the development of the report, the City has made many of the improvements to the sanitary sewer collections system and has constructed a new wastewater treatment facility. The new WWTP will accommodate the sanitary sewer needs in Pueblo to the Year 2004. The City of Pueblo's Department of Public Works is currently updating the S &G report. 9. Pueblo Airport Industrial Park Wastewater Treatment Plant Preliminary Engineering Study CH2M Hill Consultants prepared the Pueblo Airport Industrial Park Wastewater Treatment Plant and Preliminary Engineering Study for the City of Pueblo in March, 1988. A supplement to the study was prepared in February, 1989. The original study stated that the existing airport wastewater treatment facility would not be capable of processing wastewater flow and loading in the event of significant industrial growth within the Airport Industrial Park (AIP). Several industrial development scenarios were used to calculate five flow and loading projections. The study then examined five wastewater management alternatives in respect to the flow and loading projections, cost effectiveness, and other non — monetary criteria. CH2M Hill recommended that the City pump wastewater back to the main treatment plant. — 20 — In a subsequent study, CH2M Hill included another possible alternative. This alternative would require that additional wastewater be pumped back to the main City plant and that current flows be treated at the airport treatment plant. It was determined in the supplemental study that continued treatment of current flows at the airport's WWTP plant is not a feasible alternative. CH2M Hill replaced this alternative with a pumping system- -four (4) pump stations placed strategically along the route of the pipeline. They have identified this alternative to be the most economical. In addition, it allows for flexibility and better access into the system. The construction of the pipeline and pumping stations began in January, 1992, and are scheduled to be completed in the summer of 1992. Once the pipeline and pumping stations are operational, the airport's WWTP will be abandoned. C. TRANSPORTATION 1. Pueblo Analysis District Evaluation To The Year 2010 (by Traffic Zone) The Pueblo Analysis District Evaluation To The Year 2010 (by Traffic Zone) was prepared in December of 1984 by the Pueblo Regional Planning Commission. This report is part of the "Urban (3 —C) Transportation Planning Process" administered through the Urban Transportation Planning Division (UTPD) of the Pueblo Area Council of Governments (PACOG). The report is in support of the transportation network analysis conducted by agencies involved in preparation of the "Year 2010 Transportation Plan." Projections of population, dwelling units, and employment are provided for the Years 1990, 2000, and 2010. One hundred and thirty —nine (139) traffic zones in the Urban "3 —C" Analysis Area and 34 traffic zones in the non —urban area of Pueblo County have been examined. The Urban (3 —C) traffic zones were grouped into 11 analysis districts for the purpose of this report. Each zone was then examined as to its degree of develop— able land, stability of environment, activity type (residential, commercial, or industrial), predominant age of structures, and historical change in population. Population predictions were then assigned a share of expected change. The traffic zones were analyzed as to their future growth and transportation needs. Information pertinent to the Northeast Quadrant has been included in the "Transportation Network" section of this report. 2. The Year 2010 Transportation Plan The Year 2010 Transportation Plan report, October, 1989, was prepared by the Pueblo Area Council of Governments Urban Transportation Planning Division and the Colorado Department of Highways Division of Transportation Planning, in coopera— tion with the U. S. Department of Transportation Federal Highway Administration. The report is an end — product of a process that began with an analysis of the existing transportation system -- Analysis District Evaluation to the Year 2010 (by traffic zone) -- progressed through development of a long —range plan, then evolved into a continuing monitoring phase. — 21 — The Plan's objectives are: a. To adopt a revised transportation plan for the Pueblo Urbanized Area with a long —range planning horizon for the Year 2010. b. To identify transportation system needs compatible with revised projections of development in the Pueblo Urbanized Area through the Year 2010. c. To perform a systems level evaluation of social, economic, and environmental impacts of alternative land use and transportation plans. In the Northeast Quadrant, the Year 2010 Transportation Plan identifies the extension of Eagleridge Boulevard east of I -25 to the proposed Troy Avenue extension; the extension of William White Boulevard west from the airport to State Highway 47; the extension of Constitution Road east to State Highway 47; the extension of Desertflower Boulevard southeast to the University of Southern Colorado; the establishment of Alamosa Street east from the University of Southern Colorado to the proposed realignment of Baculite Mesa Road; the extension of 27th Lane north to the proposed William White Boulevard extension; the extension of Troy Avenue to the proposed Eagleridge Boulevard extension; the realignment of Baculite Mesa Road so that it intersects with the proposed extension of William White Boulevard; and the extension of 36th Lane north to United Avenue (See Map V). The Year 2010 Plan is a statement of present policy toward future needs. It reflects new development trends, new technologies, and changes in travel behavior. Employment, population, and dwelling units are projected for 139 traffic zones and seven traffic generators. Trip generation is based on projected dwelling units and employment. This data was loaded onto collectors, minor arterials, principal arterials, expressways, and freeways. 3. Pueblo Airpark Access Alternatives Study Recent developments at the AIP have resulted in traffic congestion and delays within the AIP internal traffic system during the peak hours. In response to the development and activity at the AIP, the FY 1987 Unified Planning Work Program listed Task C. 6. an "Airport Corridor Study." The Urban Transportation Planning Division contracted with the City of Pueblo's Department of Planning and Development to complete this study. The objective of this study was to identify and assess the environmental, economic, social, and traffic impacts of the alternative corridors. The six alternative corridors studied are identified on Map VI. This study concluded that no single alternative completely addressed the Airport Industrial Park's transportation needs at "build— out." However, combinations of these alternatives can provide a solution. There are many possible combinations of alternatives that together can form a course of action. The Pueblo Area Council of Governments approved and supported the construction of improvements to the Paul Harvey interchange followed by the extension of William White Boulevard to State Highway 47. If at the time when a second access is needed and the right —of —way or funding for the William White extension is not available, the 36th Lane Alternative, or 27th Lane Alternative, can address a short —term need depending upon the area of development. The course ultimately chosen will be determined by the availability of funds, timing, and need — 22 — 1. I I i I b I — I: 1 I t' :I - -j ......... ... . ... • .:1.

THE NORTHEAST QUADRANT THREE -MILE ANNEXATION PLAN PREFACE The population of the City of Pueblo is predicted to reach 110,000 persons by the Year 2000, resulting in an increase of 10,000 persons. It is anticipated that this growth will be largely fueled by increased employment at the Pueblo Airport Industrial Park. Recent trends indicate that a substantial portion of the accompanying residential growth will occur within the Northeast Quadrant. Proper planning of the development in this quadrant will ensure compatibility with existing land uses and will also ensure provision of a smooth transportation system. This plan is the result of an extensive inventory and analysis of the quadrant's environmental and man —made conditions. These conditions, along with potential development restrictions, were simultaneously analyzed in order to identify areas which would require more restrictive land use and development requirements. The Northeast Quadrant Three -Mile Annexation Plan will facilitate development by establishing logical patterns of land use based upon the needs of the community in accordance with the adopted standards and policies of the City of Pueblo. It is the intent of this Plan to encourage the most appropriate use of the land to minimize future problems resulting from incompatible development. It is further intended that by identifying the area's present resources, natural and man -made, the suitable preservation or utilization of these resources will allow for a carefully developed community. This plan is designed to meet the requirements of the Municipal Annexation Act of 1965 (Section 31- 12- 105[l][e], CRS [1988 Cum. Supp.]) as amended by Senate Bill 45 (1987). The 1987 amending bill requires that the plan describe the location, character, and extent of streets, bridges, waterways, waterfronts, parkways, playgrounds, parks, aviation fields, and other public grounds, public utilities, and terminals for water, light, sanitation, transportation, and power to be provided by the municipality. In addition, the bill requires the identification of proposed land uses for the area. The City's "Three -Mile Annexation Plan" is a compendium of all the plans and reports previously referenced in this document. It shall serve as the official "three -mile annexation plan" for the Northeast Quadrant but will not supersede the Pueblo Regional Comprehensive Development Plan except insofar as the Three -Mile Annexation Plan shall be used to identify proposed land uses in that area, defined as the "proposed urban extension area" within the Northeast Quadrant. The Three -Mile Annexation Plan shall be used to provide guidance in the review of development proposals and in the negotiation of annexation agreements. The boundary of this study area extends three miles east and north of current City limits. The study area has been partitioned into two areas by an Urban /Rural Demarcation Line: (1) a proposed urban extension area representing that portion of the Northeast Quadrant in which municipal services could logically be extended to accommodate growth (See Map II, Page 4); and - 25 - (2) the rural remainder of the study area which will not be master planned since it is not anticipated that urbanization will occur in this area within a 12 —month period following the adoption of this plan. The primary components of this plan include the identification of existing and proposed major transportation corridors, the anticipated land use around these corridors, and specific development guidelines. Secondary components include the anticipated location of major public facilities and district and urban parks within the proposed urban extension area. A. EXISTING AND PROPOSED MAJOR TRANSPORTATION CORRIDORS Roadway proposals for the Northeast Quadrant are intended to provide a transportation system that will efficiently serve a growing community. These corridors should be established so that adequate right —of —way and construction agreements can be made at the time of subdivision review. The desired alignment of these corridors are based on a minimum of one —mile spacing between the major transportation corridors' standards. The exact locations of these corridors have not yet been determined, and Map VII is intended only to offer a simulated graphic depiction of the proposed transportation pattern of the Northeast Quadrant. In addition, Map VII also delineates those roadways identified in The Year 2010 Transportation Plan report (existing corridors) from those roadways that are long —range planning (proposed) corridors. The existing major east /west transportation corridor in the Northeast Quadrant's proposed urban extension area is U. S. Highway 50 —B and the existing major north /south transportation corridor is State Highway 47. Transportation corridors and facilities proposed for the Northeast Quadrant include: 1. East /West Corridors a. The eastern extension of Eagleridge Boulevard to the proposed Troy Avenue extension (Principal Arterial). b. The western extension of William White Boulevard from the airport to State Highway 47 (Principal Arterial). c. The eastern extension of Constitution Road to State Highway 47 (Minor Arterial). d.

The realignment of Baculite Mesa Road so that it intersects with the proposed extension of William White Boulevard (Minor Arterial). d. The northern extension of 36th Lane to United Avenue (Minor Arterial). A bridge over the Fountain River and adjacent railroad tracks will be required to fully link 47th Street (Eagleridge Boulevard) with I -25 and the transportation system west of the interstate. A full interchange will be required at the point where William White Boulevard and Constitution Road (extended) intersect with State Highway 47. Major grade separated interchanges will also be required where 27th and 36th Lanes intersect with U. S. Highway 50. 3. Proposed Roadway Construction Standards All roadways within this quadrant shall be constructed to the City's standards then in effect. The City of Pueblo's goal for street design shall be no less than Level —of— Service "C," as defined by the Highway Capacity Manual It is envisioned that a new standard should be developed for transportation corridors such as William White Boulevard and Eagleridge (47th Street) Extensions. The optimum standard right —of —way (ROW) for principal arterial corridors should be 150 ft. This would include a 125 ft. roadway ROW and a 25 ft. trail ROW. The roadway would be a minimum of five lanes with a minimum of six lanes being required at the intersection of major transportation corridors, depending upon projected traffic volume. Public and private access onto these roadways shall be strictly controlled as per the Colorado State Highway Access Code The two opposing lanes of traffic would be separated by a median with a minimum width of 20 ft. These medians should be designed and landscaped in a manner that will minimize maintenance costs and in accordance with City standards. Noise abatement measures, in the form of increased building setback and /or construction of noise buffers, should be required to ensure compatibility of residential development and traffic noise. These roadways should be constructed to include a pedestrian sidewalk on one side and a trail within the 25 ft. trail ROW on the other. All trail ROW dedication should be credited to the parkland dedication where appropriate. The trails shall be constructed as per the Master Trails Plan then in effect. The City currently requires developers to pay the entire cost of roadway and sidewalk construction. Due to the fact that the envisioned standard of these corridors exceeds the City's current standard, the City may choose to study the adoption of an impact fee, or alternate system, to help fund the construction of these corridors. B. THE PROPOSED URBAN EXTENSION AREA All residential, commercial, and industrial development within the Northeast Quadrant (more specifically, the proposed urban extension area, Map II) shall conform to the City's Code of Ordinances then in effect and the goals and policies of the Pueblo Regional Comprehensive Development Plan It is anticipated the proposed urban extension area of the Northeast Quadrant will experience residential, commercial, office, and industrial growth. It is the intent of the community and of this plan that diverse housing opportunities are maintained and that commercial and industrial areas be appropriately placed in relation to existing residential areas (See Map VIII). Urban residential development should be encouraged in the area immediately north of the City limit line, east of the Fountain River to the boundary of the proposed urban extension area. Residential development should also be encouraged in the undeveloped area south of USC, west of Baculite Mesa Road. These areas represent a logical expansion of both existing residential neighborhoods and vacant land suitable for residential development. Map VIII also identifies existing industrial areas and the areas most appropriate for industrial expansion or development as well as several commercial nodes, mainly at the intersections of major transportation corridors. Industrial development should not adjoin a residential area unless a properly designed buffer is established between the two uses. The buffer design standards shall be established by the City of Pueblo. Clustering of subregional and highway commercial uses should be encouraged, while "strip" type of commercial development should be discouraged. The Federal Highway Administration (FHWA) has established Design Noise Level (DNL) guidelines to protect various land uses and noise — sensitive activities (See Table I). These levels, expressed in decibels on the "A" weighted scale (dBA), represent the upper limit of acceptable traffic noise and are used to evaluate the degree of impact traffic noise has on human activities. These guidelines are imposed on those roadways utilizing Federal funding. If traffic noise computer modeling indicates that noise — abatement measures are necessary, construction of noise barrier walls and /or non — construction techniques are considered. Non construction techniques include prohibition or time restrictions on certain vehicle types (trucks), exclusive land designation, modifications to the speed limit, and increased setbacks for construction. All future development shall comply with these guidelines when appropriate. Additional restrictions on both development and noise abatement regarding Airport noise contours are discussed in the next section. Portions of the proposed urban extension area are within a 100 —year floodplain. These areas are adjacent to the Fountain River and drainage ways at the Airport Industrial Park. Unless development can qualify for a Flood Hazard Development Permit, most types of development within these floodplains should be discouraged. Due to floodplain development restrictions, the majority of those areas within a 100 —year floodplain should be encouraged to be utilized as "open space" or "open space /wildlife." — 29 — LU s 0, 0 00 — r• i � Y I 1 j�D�M7YAt �' �" O 'i � I `ma pe � � ` � • -fi t.

PUEBLO MEMORIAL AIRPORT AND INDUSTRIAL PARK 1. Airport The Pueblo Memorial Airport and adjacent industrial park is located six miles east of Downtown Pueblo and occupies 3,800 acres of land. The airport was established in 1943 as an Army Air Corps Base. In 1953, the facility was transferred to the City for use as a municipal airport. Occupying 2,900 acres with three runways, terminal and complete air -side facilities, the airport serves as a major air facility to Southern Colorado. The Master Plan for Pueblo Memorial Airport by Isbill Associates, Inc., refers to the primary trade area as 7 the geographic area from where the greatest majority of airline passengers are normally generated." The "primary trade area" for Pueblo Memorial Airport includes Pueblo, Colorado City, and Pueblo West. "Secondary trade areas" extend to La Junta, Rocky Ford, Walsenburg, and small mountain resorts. The volume and type of air traffic (passenger or cargo) is related to the population, seasonal employment, and economic climate of these trade areas. Based on increasing population, rising employment opportunities, and increasing business and industry in the Pueblo area, an increasing demand for all airport services is probable. Pueblo's Aviation Director states that capacity at the airport is four commercial airlines. Beyond four, the terminal building and other facilities would be in need of major expansion. The operations budget for the airport is allocated by the City of Pueblo. Additional funding for capital improvements is available through the Federal Aviation Administration's Entitlement Program. Pueblo Memorial Airport has approximately $2.5 million in proposed improvement projects planned. Federal funding is allocated through a priority system. Projects such as those concerning air -side facilities are priority and receive funding over projects to renovate public areas. It is unlikely that Pueblo will receive the entire $2.5 million as not all proposed projects are top priority. 2. The Airport Industrial Park The remaining 900 acres not committed to airport operations have been made available for light industrial uses. This zone (I -1 or I -2) allows for wholesaling activities, printing, warehousing, and some types of manufacturing. Initially, all the land in the AIP was owned by the City. Between 1953 and the early 1980's, a small number of industrial users, including Dana Corporation, Metal Processing, Pueblo Diesel, OK Tooling, the Government Printing Office and Martec, moved into the AIP. In the early 1980's, the Pueblo Economic Development Corporation (PEDCo), a joint public /private economic development effort, was founded. PEDCo began actively marketing the community and promoting the industrial development of the AIP. The first major corporation to respond to the effort was the Sperry Corporation, now Unisys, which announced their intention to locate in Pueblo in 1984. They were - 32 - followed by the Target Distribution Center, McDonnell Kurt Manufacturing, PCL Packaging, Atlas Pacific, Pryor Glenn Trucking Company, Kaiser Aerospace Electronics, and are 496 acres of developable land still available at t' increased from an available average AIP census prior to the 660 to an actual census of approximately 2,500 in October of Douglas Astronautics, Giggey, Trane Company, B. F. Goodrich. There ie AIP. Employment has Sperry announcement of 1987. 3. Fire Protection -- Airport and Airport Industrial Park (AIP A City fire station is located at the Pueblo Memorial Airport. It is equipped with a three —way pumper truck, two crash trucks with foam and powder fire retardant, and three two — person shifts. This station's protection service area includes the airport terminal, air side facilities, and the industrial park. Presently, the annual operation's expenditure for the airport station is $248,000 (1988). In the case of an emergency, the airport fire fighters and at least one station from the City are simultaneously dispatched. The airport crew arrives within minutes and after assessing the scene can request additional support. If an emergency occurs in the AIP, the same sequence is followed; however, when sufficient support crews arrive, the airport team must return to its station so as to ready itself for any air —side emergency. The City Fire and County Volunteer Rural Fire Departments have a standing Mutual Aid Agreement which provides that either department will respond to aid the other on request. The one exception is in the event of an air —side emergency, in which case the Rural County fire fighters are immediately dispatched. Rural Station No. 2, located on Baxter Road, is two miles from the airport and has a response time of two to three minutes. It is staffed by a four — person crew and equipped with a pumper truck and foam fire retardants. 4. Emergency Services The greatest shortfall in emergency services at the airport, according to the Aviation Director, is that of medical attention. Firemen and police officers are often licensed as Emergency Medical Technicians (EMTs), but any advanced aid or transportation to a medical facility must first be dispatched to the airport from the City. A rather lengthy delay is incurred and this could be detrimental in the case of an emergency. 5. Airport Police Protection The airport and the AIP are primarily a City development project on City land. Currently, all law enforcement and regulation is provided by the Pueblo City Police Department with the assistance of airport /private agency security personnel. — 33 — The City Police Department has incorporated the airport into the City's Southeast area police beat. However, because of the busy nature of this patrol, the airport is not frequently accommodated. Night shifts are not scheduled to patrol the airport or the AIP. Federal law requires that a uniformed police officer be present at the airport terminal when departing passengers are screened. No officer is permanently assigned to this duty. When a commercial airline is scheduled for departure, a City police officer must fulfill the duties at the airport. City Law Enforcement Code 3 -1 -4 states that all Pueblo City traffic ordinances apply to the airport and that the airport director is responsible for the enforcement of these ordinances. Currently, airport personnel enforce parking regulations and City police enforce all other traffic ordinances. City ordinances on personal conduct also apply at the airport and are enforced by City police. There are no formal, written agreements with the County indicating under whose jurisdiction the airport falls -- County or City. Also, there are no written guarantees with the individual industries that City police shall provide the protection. Airport security personnel patrol the airport and will assist any law enforcement officer or private agency security guard. The airport security guards are issued a police commission which allows them to detain suspects and issue traffic and parking citations. They do not carry firearms. Target and Unisys are the only industries employing security personnel. These guards carry firearms but do not leave the premises of their respective employers. If law enforcement services continue as are currently practiced, and if the airport builds out, a new City patrol beat may be needed. Annexation will neces— sitate this beat and will include the revenue to pay for it. Currently, City police protection to the airport, terminal, and industrial park is provided from other City patrol beats and is not paid for from airport revenue or industry service fees. 6. Pueblo Memorial Airport Noise Zones Pueblo Memorial Airport, located four miles east of the City of Pueblo, is classified in the National Airport System Plan as a non —hub, medium — density, secondary air — carrier airport. It's annual aircraft operations range falls between 100,000- 250,000 and 50,000- 100,000 annual passenger enplanements (departures). In 1991, there were 45,004 enplaned passengers. Air carrier service is provided by Continental Express, Trans World Airways, and United Express Airlines. The Airport facilities are available to both civilian and military uses. Flight training occurs 24 hours daily by the Army, United Airlines, Aspen Airlines, Continental Express Airlines, Trans Colorado Airlines, and Evergreen International (for United Postal Service). The Airport has two runways. The main runway is 10,496 x 150 feet east /west. The secondary runway is 7,000 x 150 feet north /south. Over 90 percent of all general aviation and military operations occur on the east —west runway. — 34 — Isbill Associates, Inc., prepared an Airport Master Plan for the Airport in 1975. Noise zones, or those areas significantly impacted by aircraft noise, were measured by Composite Noise Ratings (CNR's). Three following zones were identified: Zone 5 - -115+ CNR's - -the highest next to the runway; Zone 2-- 100 -115 CNR's in the takeoff and landing areas; and Zone 1--90 -100 CNR's outside those areas (See Map IX). Residential land uses were "Normally Acceptable" by these FAA standards in Zone 1, "Normally Unacceptable" in Zone 2, and "Clearly Unacceptable" in Zone 3. These FAA standards are guidelines and "are not intended to substitute Federally determined land uses for those determined to be appropriate by local authorities in response to locally determined needs and values in achieving noise compatible land uses." These zones are indicative of older aircraft with noisier engines using different takeoff and landing patterns than today's quieter planes. Pursuant to the Airport and Airway Improvement Act of 1982, the FAA has streamlined the process for determining noise exposure levels and land use capabilities around airports. All Federal noise levels are now measured in Average Day —Night Sound Levels (LDN). Through the use of quieter aircraft and different takeoff and landing patterns, the noise zones have changed since 1975 (See Map X). Through the use of a sophisticated computer modeling program developed by the FAA, aircraft types and takeoff and landing patterns are computed for a more accurate depiction of today's noise levels. These new zones which were prepared in 1987 by the State Department of Local Affairs for the City of Pueblo depict noise areas, especially in Zone 2, differently than in 1975. This study, while not approved by the FAA, is indicative of a change in zone areas. A new Federal Aviation Regulation (FAR) 150 noise study will be forthcoming in 1992. This new study will be the most accurate study yet prepared. It will use manual calculations, actual field measurements, and computer modeling. The CNR and LDN noise levels are compared in Table II. Land use compatibility tables, recommended by the FAA are listed in Table III. Zone 3 is recommended only for open space, agriculture, or industrial development. In Zones 1 and 2, residential development and other land uses are recommended only with noise abatement construction. — 35 — - Q , l 4I A.

The responsibility for determining the acceptable and permissible land uses remains with the local authorities. FAA determinations under FAR Part 150 are not intended to substitute federally- determined land uses for those determined to be appropriate by local authorities in response to locally- determined needs and values in achieving noise compatible land uses. Y (Yes) -- Land use and related structures compatible without restrictions. N (No) -- Land Use and related structures are not compatible and should be prohibited. NLR -- Noise Level Reduction (outdoor to indoor) to be achieved through incorporation of noise attenuation Into the design and construction or the structure. 20, 25, or 30 -- Land use and related structure generally compatible, measures to achieve NLR or 25, 30, or 35 must be incorporated into design and construction of structure. 1- Where the community determines that residential uses must be allowed, measures to achieve outdoor to indoor Noise Level Reduction (NLR) of at least 25 d8 and 30 dB should be Incorporated Into building codes and be con- sidered in individual approvals. Normal construction can be expected to provide a NLR of 20 dB, thus, the reduction requirements are often stated as 5, 10, or 15 d8 over standard construction and normally assume mechanical ventilation and closed windows year round. However, the use of NLR criteria will not eliminate out- door noise problems. 2- Measures to achieve NLR of 25 must be incorporated Into the design and construction of portions of these build - Ings where the public is received, office areas, noise- sensitive areas or where the normal noise level is low. 3- Measures to achieve NLR of 30 must be Incorporated into the design and construction or portions of these build - Ings where the public is received, office areas, noise - sensitive areas or where the normal noise level Is low. 4- Measures to achieve NLR of 35 must be Incorporated Into the design and construction of portions of these build- ings where the public Is received, office areas, noise - sensitive areas or where the normal noise level is low. 5- Land use compatible provided special sound reinforcement systems are installed. 6- Residential buildings require an NLR of 25. 7- Residential buildings require an NLR of 30. 8- Residential buildings not permitted. sources: FAR Part 150, Airport Noise Compatibility Planning, DOT -FAA, January 1981, Appendix A - Table 2, page 11. - 39 - D. DEVELOPMENT GUIDELINES All development within the Northeast Quadrant shall be undertaken in accordance with the then - existing City Code of Ordinance and the Policies of the Pueblo Regional Comprehensive Development Plan The following guidelines should be considered at the time of development for properties within this quadrant. 1. Residential a. Transitional high- density residential (R -4, R -5, R -6) or office (0 -1) development between single - family residential (R -1, R -2) and commercial (B -1, B -2, B -3) land uses should occur. b. No single - family residential units (R -1, R -2, R -3, R -4) shall be permitted private access onto major transportation corridors. c. The Colorado State Highway Access Code shall be followed in permitting a common access onto major transportation corridors for multiple residential units (R -5, R -6, R -7). d. All residential units adjacent to principal arterials and expressways shall be required to provide properly engineered noise buffers (e.g., berms, fencing, landscaping, or increased setback) between the residence and the roadway. The buffers must meet a design standard, to be established by the City of Pueblo. e. Every attempt should be made to pursue compatible zoning and land use policies in those areas impacted by Airport operations. It is highly recommended that residential development within Airport Noise Zones 1, 2, and 3 be in accord with the standards found in Table III, page 39. f. Petitioners for annexations within Noise Zones 1, 2, and 3 will be required to grant to the City the Standard Avigation Easement, attached as Appendix 1. g. Every effort should be made to link residential development with the City's Master Trails System. 2. Commercial a. Clustering of neighborhood and highway commercial uses depicted as commercial nodes on Map VIII should be permitted if compatible with existing land uses. b. The Colorado State Highway Access Code shall be followed in permitting a commercial access onto major transportation corridors. c. Commercial development within Airport Noise Zones 1, 2, and 3 should be in accord with the standards found in Table III, page 39. d. Petitioners within all noise zones within the Northeast Quadrant will be required to grant to the City the Standard Avigation Easement, attached as Appendix 1. - 40 - 3. Industrial a. Industrial development should not be permitted adjacent to residential areas. If such an industrial area develops, it must be contingent upon the construction of an adequate buffer between the two uses. b. The Colorado State Highway Access Code shall be followed in permitting an industrial access onto major transportation corridors. c. It is recommended that light industrial development be allowed to occur in the areas depicted on Map VIII, page 30. These areas include the Airport Industrial Park, the area south of the proposed William White Boulevard extension between Highway 47 and the AIP, and between I -25 and the Fountain River near the northern City limits boundary. d. All industrial development within Airport Noise Zones 1, 2, and 3 should be in accord with the standards found in Table III, page 39. e. Petitioners within all noise Zones within the Northeast Quadrant will be required to grant to the City the Standard Avigation Easement, attached as Appendix 1. 4. Mineral Resource Extraction Area a. All mineral resource extraction areas adjacent to residential units shall be required to provide properly engineered noise buffers between the extraction area and the residences. The buffers must meet a design standard, to be established by the City of Pueblo. E. PUBLIC FACILITIES 1. Police There are currently no plans to locate a Police substation within the area covered by the Three -Mile Annexation Plan. 2. Fire Fire Department standards require that new fire stations be central to their service area. No point should be further than one and one -half miles from the station. Additional fire stations will be required to provide protection to the proposed urban extension area at build -out. A tentative site for a new fire station in the University Park neighborhood has been selected. The site fronts on the east side of Jerry Murphy Boulevard, south of 47th Street, and north of Candytuft Boulevard. A new fire station will be built on this site if investigations conclude that the site can service the University Park neighborhood and residential development proposed for the City's new municipal golf course. Construction of the fire station is expected to commence as early as 1991 -92 if funds are available. - 41 - 3. Schools The proposed urban extension area is within both School Districts Nos. 60 and 70. Decisions to build new school facilities are made on a case -by -case basis. School District No. 60 currently possesses a future school site in the University Park neighborhood. However, a decision has not as yet been made on when this school site will be developed. When it is developed, it will be as an elementary school. School District No. 70 has discussed the possibility of reopening Baxter Elementary (located in the Southeast Quadrant) if enrollment warrants it. F. PARKS, OPEN SPACE. AND TRAILS 1. Parks As residential development occurs, it may become necessary to develop new parks in these areas to meet new demands. Parks shall be dedicated by the developer of residential areas, as per the City Subdivision Ordinance, Section 12- 4 -7(e), or as may subsequently be amended. The City of Pueblo will not accept a dedication of a park site unless said property meets the criteria for the provision of free water set forth by the City of Pueblo Board of Water Works (Board of Water Works Rules and Regulations, October 18, 1983). a. Neighborhood Park Neighborhood parks shall be developed on a minimum of five acres of land accessible to all subdivision residents. These parks shall have sufficient areas for recreational activities including but not limited to playgrounds, multipurpose courts, and open and shaded grassed areas. Dedicated parkland shall be located, when possible, adjacent to school district facilities to share use. Dedication of drainage ways, steep slopes, or other "nondevelopable land" for use as parks may not be permitted. The City may accept drainage ways as a part of the master trails system if they are identified on the master trails map and are improved in accordance with the Storm Drainage Criteria Manual b. District Park A district park should be developed for the Northeast area and contain facilities and programming for all ages. This park should contain a minimum of 25 acres. It would provide specialized facilities such as a swimming pool, court sports, a recreation center, and regulation -size playing fields. Large grass and tree areas and specially landscaped open areas should also be provided. Land currently owned by the City between the Fountain Creek and University Park Subdivision has been identified as a possible district park site. - 42 - 3. Industrial a. Industrial development should not be permitted adjacent to residential areas. If such an industrial area develops, it must be contingent upon the construction of an adequate buffer between the two uses. b. The Colorado State Highway Access Code shall be followed in permitting an industrial access onto major transportation corridors. c. It is recommended that light industrial development be allowed to occur in the areas depicted on Map VIII, page 30. These areas include the Airport Industrial Park, the area south of the proposed William White Boulevard extension between Highway 47 and the AIP, and between I -25 and the Fountain River near the northern City limits boundary. d. All industrial development within Airport Noise Zones 1, 2, and 3 should be in accord with the standards found in Table III, page 39. e. Petitioners within all noise zones within the Northeast Quadrant will be required to grant to the City the Standard Avigation Easement, attached as Appendix 1. 4. Mineral Resource Extraction Area a. All mineral resource extraction areas adjacent to residential units shall be required to provide properly engineered noise buffers between the extraction area and the residences. The buffers must meet a design standard, to be established by the City of Pueblo. E. PUBLIC FACILITIES 1. Police There are currently no plans to locate a Police substation within the area covered by the Three -Mile Annexation Plan. 2. Fire Fire Department standards require that new fire stations be central to their service area. No point should be further than one and one -half miles from the station. Additional fire stations will be required to provide protection to the proposed urban extension area at build -out. A tentative site for a new fire station in the University Park neighborhood has been selected. The site fronts on the east side of Jerry Murphy Boulevard, south of 47th Street, and north of Candytuft Boulevard. A new fire station will be built on this site if investigations conclude that the site can service the University Park neighborhood and residential development proposed for the City's new municipal golf course. Construction of the fire station is expected to commence as early as 1991 -92 if funds are available. - 41 - c. Regional Park Every attempt should be made to acquire over 200 acres for a regional "urban Park" on the west side of Baculite Mesa Road (See Map VIII, pg. 30). This site would be open for multiple recreational uses including but not limited to ball fields, tennis courts, a swimming pool, soccer fields, picnic areas, and playgrounds. The area contains three sand and gravel pits which, once renovated, would service as a natural scenic area. There is also a spring which could be incorporated into the plans for the area. 2. Open Space Open spaces are areas of non — developed land. They can include or consist of unique natural areas, historic locations, or other amenities. Such spaces can create a community's individual identity. Open space offers relief from urban activities and growth pressures. The southern tip of Baculite Mesa should be acquired, as indicated on the proposed land use map (Map VIII), and maintained in its natural state. Open spaces shall remain in their natural state only to be traversed by developed bicycle and pedestrian trails and scenic, historic, or archaeological viewing areas. One— hundred year floodplains, such as the area bordering the Fountain River, should remain undeveloped in their natural state. A technical evaluation demonstrates that encroachments will not result in any increase in flood levels during the occurrence of the base flood discharge. In the case that development on a floodplain is to be considered, a flood hazard development permit shall be obtained. The Flood Hazard Development Permit must demonstrate that the encroachment shall not result in any increase in flood levels during the occurrence of the base flood discharge. Any development within the floodplain shall be in accordance with the City Code of Ordinances, then in effect. 3. Trails To ensure continuity of the bicycle and pedestrian trails system, all developers should be responsible for the dedication of right —of —way and the extension of those trail corridors through their development. Alternately, they may be required to pay a fee towards construction of the master trails system. These trails shall be identified by the City of Pueblo's Bicycle System and Trails Plan, then in effect. The trails and bicycle lane system should be located along major roadways, natural scenic areas, river floodplains, arroyos, parks and school locations, watercourses, and central commercial centers. All trails shall be constructed pursuant to standards set forth by the Bicycle System and Trails Plan, then in effect. Map XI illustrates potential trail locations. These lie primarily parallel to major roadways, as identified on the "Proposed Transportation Corridors" Map. — 43 — _ ��n�tfl� T►R���uu�n��n�n���u���ntl iinun���unn 4 A";,i•*+�•��+•r+�++:.�� . •.. .1 : 'Nl H19C �." 41 Y z a o z o B I r _, !•� Q ¢ z o J vi w O � ¢ W Ort °- o 1 I< { J fA N 0- 0 0 - w � a � `s a J O _¢ ¢ v x O CC cr CL J J r z J J~ z _ V) ¢¢�� w 1 _ CO a ■ ■ C7 W W U U a x O" IL cc cc 0 0 -�� W av_, = �.��� N'. 5_ 0 1 ^.4csa — 1 r7q, Y8 t olls I •� 9 _........ to PEI Fi O W U 04 P a tP4 a 1SH91N1 City of Pueblo Department of Planning & Development MAP: NORTHEAST QUADRANT ANNEXATION MASTER PLAN XI — 44 — V. ENVIRONMENTAL ANALYSIS PREFACE The purpose of this review is to provide an understanding of current environmental conditions, identify potential hazards, and determine the potential for mineral resource extractions in the Northeast Quadrant. The results of this review will then be used as a planning tool to ensure that environmental constraints are recognized and mitigated prior to development and that environmentally sensitive lands are conserved. Section A, Environmental Inventory, identifies geological, topographical, and biological characteristics of the study area. Climate, air quality, and water quality will also be addressed. Section B, Environmental Constraints, identifies potential hazardous areas and mineral resource reserves. A. ENVIRONMENTAL INVENTORY Bedrock Geolo Bedrock is the undisturbed, unbroken rock at earth's surface upon which transported surficial deposits lie. The bedrock in the Northeast Quadrant is primarily of sediment and marine origin (70 to 100 million years old). From an economic point of view, sedimentary rocks are extremely important because many of our natural resources are formed by sedimentary processes; the most familiar found in the Northeast Quadrant include sand and gravel. The City, County, and State extract sand and gravel from gravel pits located in this quadrant. In addition, since sedimentary rocks are produced by interactions of the hydrologic system and the earth's crust, they record the history of physical and biological events on the earth. From this record, we are able to interpret ancient mountain building and specific erosion patterns that may impact development. The bedrock in the Northeast Quadrant consists of Pierre Shales and Niobrara Formations (See Map XII). Members of the Pierre Shales include Rusty Zone member, Sharon Springs member, Transition member, Teppe Zone member, and Apache Creek Sandstone member. Members of the Niobrara Formations include Upper Chalky Shale and the Overlying Upper Chalk member. The Upper Chalky Shale is 265 ft. thick and the Pierre Shale Teppe Zone and Transition Zone are 635 feet and 228 ft. thick, respectively. These swelling clay members with limited beds of Bentonite can present problems for excavation, have high shrink —swell properties, and are not suitable for use as a material directly under a road. Corresponding geologic properties of both bedrock and surficial geologic amounts can be found in Table IV. — 45 — u.

Surficial Geology Much of the bedrock in the Northeast Quadrant is covered with surficial deposits (See Map XIII). This material is composed of some clay and much silt, sand, and gravel that have been deposited by running water and wind. These surficial deposits overlie the sedimentary bedrock except where faulting, folding, or erosion have exposed bedrock sections. Surficial deposits in the Northeast Quadrant include Broadway Alluvium, Colluvium, Eolian Sand, Louviers Alluvium, Nussbaum Alluvium, Piney —Creek Alluvium, Post —Piney Creek Alluvium, and Verdes Alluvium. Some of these deposits can present flood hazards or engineering problems due to expansive soils. The geologic properties of these deposits are listed on Table V. a. Soils A soil association refers to a landscape that has a distinctive pattern of soils composition in defined proportions. Map XIII illustrates soil associations in the Northeast Quadrant. These soils have been classified into three groups: River Bottom and Terrace Soils, Plains Soils, and Foothills Soils. The following information provided in this Master Plan refers to general soil compositions. More specific information is available and should be referenced for detailed Planning and Development decisions. As shown on Map XIV, the soils in the Northeast Quadrant and their characteristics are: (1) River Bottom and Terrace Soils #7: Las Association -Warm, deep, poorly and somewhat poorly drained, nearly level soils on floodplains. (2) Plains Soils #8: Manvel, Minnequa, and Penrose Association - -Warm, deep, shallow, and well— drained gently sloping soils on uplands plains. (3) Foothills Soils #39: Casca,jo and Sunsil Association Warm, deep, and shallow, excessively drained to well — drained, and gently sloping to moderately steep soils on uplands breaks. #46: Penrose Association -Warm, shallow, well— drained steep and moderately steep soils on uplands breaks. #47: Gaynor, Samsil, and Limon Associatio deep, and shallow, well drained, gently sloping to moderately steep soils on uplands breaks.

Landforms Landforms refer to the topographical characteristics in a specific area. They result from the interaction of three factors -- structure, process, and stage. Structure refers to an existing surface or geologic structure found in the area. Process is the natural and chemical erosional element which modifies the structure. Stage indicates the length of time in which the erosion takes place. Elevation in the study area ranges from 4,550 ft. above sea level at the Arkansas River to 5,234 ft. above sea level at Baculite Mesa. Physical characteristics of the Northeast Quadrant are illustrated on Map XV; they include a mesa and butte, a terrace mesa, the floodplains of the Fountain Creek and Arkansas River, and rolling plains. 4. Drainage The area slopes from Baculite Mesa and adjoining mesas southward to the Arkansas River and southwest to the Fountain Creek. Slopes on the mesas range from seven to twenty -five percent and from three to seven percent over the lowland prairie. Much of the Pueblo Memorial Airport and industrial park have been graded to slopes of less than three percent. There are eight sub - drainage basins which flow into the Fountain Creek and Arkansas River; they are the East Dry Creek and seven unnamed basins (See Map XVI). These arroyos, or intermittent stream courses, have been created in highly erosive silt and clay alluviums. Stream flows are created primarily during thunderstorms in which rapid runoffs flow into the arroyos. The environmental constraints of these arroyos are described in Section B. a. Floodplains Five watercourses, two rivers, and three arroyos are classified as 100 -year floodplains in this study. A 100 -year floodplain is considered an area with a one percent chance of flooding in any single year, or once every 100 years. The Fountain Creek, Arkansas River, and three arroyos, including the East Dry Creek, have significant drainage basins and are classified as Zone A, 100 -year floodplains (See Map XVI). Environmental constraints that result from these floodplain hazards are described in the accompanying Section B. b. Wetlands Wetlands are referred to as those areas that are inundated by surface or groundwater with a frequency sufficient to support a prevalence of vegetative or aquatic life. Wetlands generally include swamps, marshes, bogs, and similar areas such as sloughs, potholes, wet meadows, sewer overflows, mud flats, and natural ponds. There are no wetlands within the study area. - 53 - 5 • K � 1t i,� ,� ;( �,.���,; :i �y�. ;,�a�:'c. �� �/, �'r1� {- MAP KEY Mesa &Butte �''a' {� �� }J�, �'l �j' s;�,r =� Terrace north f� ;,�� r y �� ` � � � � k i I� � r rr.r•`�' /��� rS1� `� �`r, Floodplain Rolling Plain Zr 'Jl.r,f tv J rl;� fi,` j; fr Y / •�� �r�;��r � /1 � /C•� �jr:r��f - 1 f { y !

Climate The Pueblo region is located in the transition zone between the temperate and hot, arid climatic regions. The climate is characterized by abundant sunshine, low relative humidity, light to moderate winds, large daily temperature variations, and light precipitation. Average annual precipitation is approximately 11.6 inches. Temperatures in the summer reach 90 degrees or more, approximately one out of every two days. Afternoon thunderstorms account for much of the summer precipita— tion, and the probability of measurable precipitation is one day out of four. 6. Flora and Fauna Plant and animal associations are groups of species co— existing in a complementary fashion. Groups of associations are called communities. A biotic zone consists of an association of communities. These zones are defined by soil, moisture, climate, and the biotic history of the area. These conditions determine the nature and distribution of plant and animal habitat. The Northeast Quadrant study area is contained within the "Plains" biotic zone. This zone characteristically lies between 3,500 and 5,500 ft. in elevation and experiences minimal precipitation. The area is considered semiarid. Most of the vegetation can tolerate long periods of drought. The dominant vegetation is prairie grass. The plant association in the Northeast Quadrant is the Grasslands of the Plains which occur in the areas described below: a. Grasslands of the Plains (1) Grasses include Alkali sacaton, Inland salt grass, Galleta, Blue grama, and Western wheatgrass. Flowering saltbrush, Rabbitbrush, and Greasewood are the predominate shrubs and are normally found on swale and floodplain portions of this site. (2) Blue grama is the dominant grass occurring with Sideoats grama, Little bluestem, Needle and Thread, Indian rice grass, and Prickly —pear cactus on gravelly soils with Sand bluestem, Prairie sandreed, Needle and Thread, Indian rice grass, Sand dropseed, and Prairie three awn on sandy soils. (3) Sand bluestem, Prairie sandreed, Sand dropseed, Needle and Thread, Blue grama, Prickly —pear cactus, and Sand sage on sandhills. Wildlife populations interacting with landforms, soils, moisture, climate, plant associations, and other animals create wildlife habitat. The more habitat available, the greater the diversity of species which can be supported. The habitat groupings in the Northeast Quadrant are Urban and Grasslands. Habitat is valued in terms of food sources, vegetative cover, water availability, shelter, and breeding grounds. Different animal species relate to different habitat. Disturbance to or extinction of any one habitat, plant, or animal species can have an impact on other species. Preservation and protection of habitat and species is imperative in maintaining the integrity of a native plant and animal populations. — 56 — 7. Water Quality The Northeast Quadrant consists of six drainage subbasins (See Map XVI). The subbasins are tributary to the Arkansas River Basin. to ensure the quality and acceptability of Colorado's waters for beneficial use, water quality standards and classifications have been adopted by and for the waters of the State, including the Arkansas River. The mainstem segment of the Arkansas River within the study area is referred to as the Lower Arkansas River, Segment 1, by the Section 208 Water Quality Plan. It is located from a point immediately above the confluence with Fountain Creek to the Colorado /Kansas border and is classified as a Class 2 Recreation and Warm Water Aquatic Life, Water Supply and Agriculture stream segment. Using or traveling the Arkansas River within City limits is not allowed. The 1977 Section 208 Stream Segment Analysis describes this segment of the Arkansas River as a warm Water slow flowing river highly affected by a large number of point and nonpoint sources that affect the merging of wastewater effluent and tributary wastes. The parameters and results in which this stream segment was analyzed include: PARAMETER RESULT Dissolved Oxygen Within Safe Limits Un- ionized Ammonia Within Safe Limits Fecal Coliform Within Safe Limits Suspended Soils Exceeds Recommended Limits for Cold Water Aquatic Life These conditions support the use of this segment as a Primary Contact Recreation -- Aquatic Life -- Surface Water Supply area. The 1987 Section 208 Plan Update considers this segment to have "medium- priority" impact. This is to say that "water quality data indicate these stream segments on the Fountain Creek and Arkansas River may be adversely impacted by nonpoint pollution sources, but no human health hazard currently exists. Water quality standards for aquatic life and agriculture are being exceeded. The Lower Fountain Creek was monitored in 1985 for Storm Event water quality. Sulfate, Chloride, and Nitrate (n) water quality constituents were found to be higher in concentration, in most cases, in ambient water than storm water. Groundwater quality has not been historically a problem in this area and was not analyzed in the 1977 or 1987 208 Plans. - 57 - Fountain Creek, as a tributary to the Arkansas River, is classified as Class 2 Recreation, Agriculture, and Domestic Water Supply. This segment of the Fountain Creek has no aquatic life classification as the stream is largely barren of aquatic life except for some migration of the Arkansas Darter from selected tributaries (these tributaries have an aquatic life classification). Widespread socioeconomic inputs would result if the Fountain Creek were classified for aquatic life. The Fountain Creek's quality appears to be incorrectable in a 20 —year time period due to past human induced conditions. 8. Air Quality Air quality in the Northeast Quadrant poses no problem to human health and welfare. The entire Pueblo region complies with all National Ambient Air Quality Standards pursuant to the Clean Air Act, 1963, as amended. Recent clean air programs and the CF &I Steel Corporation production cutbacks have resulted in vast improvements in Pueblo's air quality. Air quality is determined by measuring specific particles suspended in the atmosphere. Beginning in 1985, the Pueblo City— County Health Department has monitored Total Suspended Particulates (TSPs). The results over time have indicated a steady increase in air quality. In October, 1987, a new system- - Particulate Matter 10 Microns or less (PM- 10) - -was installed. All monitoring is now done by PM -10, as this system allows for a more detailed analysis. Results indicate that the Pueblo region has a 14 -20 percent chance of noncompliance with Federal Ambient Air Quality Standards. This is considered a low priority of concern and only requires that the region continue to monitor air quality on a regular basis. Those areas with a 20 percent or greater chance of noncompliance must have a State Implementation Plan in place. The implementation plan outlines procedures directed at decreasing the chance of noncompliance. Currently, there is only one PM -10 monitoring station in the Pueblo area which is located atop City— County Health Department Office in Downtown Pueblo. It should be noted that new development may cause a short —term increase in suspended particulates as a result of cut and fill, grading, and other construction activities. Such activities may require the issuance of an emissions permit from either the State or local Health Department. Carbon monoxide, of concern to several Colorado cities, has not reached severe levels in Pueblo. The City is thereby not required to monitor this particular pollutant. B. ENVIRONMENTAL CONSTRAINTS Areas in which environmental hazards exist may not be the optimum areas for land use development projects. Those areas where steep or unstable slopes, floodplains, erodible soils, or large arroyos exist are fragile environmental zones and can place constraints on development. Prior to any new development, an environmental analysis should indicate areas of environmental sensitivity. Mitigating measures should then be utilized in planning and construction. The severity and location of various environmental hazards and of mineral resource areas within Pueblo County were computer- mapped via a program called IMGRID Analysis (Improved Grid). This program was developed by the Department of Architecture of Harvard University's School of Design. The potential hazards analyzed for Pueblo County and included in this report are: (1) Floodplain Hazards and Drainage Needs; (2) Wildfire Hazards; (3) Geologic Hazards - -(a) Unstable Slopes; (b) Mud Flow /Debris Fans; (c) Expansive Soils and Rocks; (d) Ground Subsidence; (e) Seismic Effects; and (f) Erosion; (4) Mineral Resource Areas; and (5) Environmental Hazards Composite. The following text describes potential hazards in the Northeast Quadrant: Floodolain Hazards and Drainage Needs A floodplain is an area along the course of a river or stream that is naturally subject to flooding. A floodplain is described by Colorado statutes (24- 65.1- 103[71) as an area adjacent to a stream, which is subject to flooding as a result of the occurrence of an intermediate regional flood and which area thus is so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property. The 100 -year floodplains are such adverse areas. The 100 -year floodplains in this study area include the Fountain Creek, the Arkansas River, the East Dry Creek, and two unidentified drainages located within the airport boundaries (See Map XVI). Fine silt, mud, and sand are deposited on these floodplains when water volume is high. During each high water stage, these deposits (called alluvium beds) become thicker and wider. Simultaneously, erosion creates steep, unstable river banks. According to Federal law, the floodplain should be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. It is the goal of Pueblo's zoning and development procedures to protect floodplains in accordance with this law. Development in the floodplain is restricted unless technical evaluation demonstrates that encroachments shall not result in flood levels (City Ordinance Title XVII Section 9). Construction on fringe areas should require special floodproofing measures found in Title XVII of the Zoning Ordinances for the City of Pueblo. - 59 - Prior to development, a master drainage plan must be prepared which would discuss natural flows, additional hydraulic flow generated by new developments, and mitigating measures necessary to ensure adequate drainage. Improvements might include holding ponds, diversion channels, check dams, drainage pipes, gutters, and channel boxes. Hydrologically, the results are similar but the cost and amount of land necessary for these improvements varies. 2. Wildfire Hazards A wildfire is any fire that is burning out of control including brush fires, forest fires, grass fires, and structure fires. A number of elements must be present in order to create an area of wildfire hazard potential. Climate, fuel loads, topography, and wind patterns all play a determining role in identifying fire sensitive areas. High wildfire hazardous areas have been identified by IMGRID on the west side of Baculite Mesa (See Map XVII). 3. Geologic Hazards Geologic hazards are geologic phenomenon which are so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property. The term includes but is not limited to unstable slopes (the southern tip of Baculite Mesa); mud flows /debris fans; expansive soils and rocks; ground subsidence; seismic effects; erosion; radioactivity (no hazards defined by IMGRID); rockfalls (no hazards in the area); landslides (potentially hazardous in the southern tip of Baculite Mesa); and avalanches (no hazards in the area) (See Map XVII). a. Unstable Slopes An unstable slope is an area where gravity can cause loose dirt, gravel, or any surface materials to move downhill. Natural and man —made slopes occur from weathering, erosion, filling or cutting away existing slopes, or altering natural drainages. River floodplains create a natural unstable slope on channel banks. Potentially unstable slopes have been identified on Baculite Mesa (See Map XVII). These slopes can be very dangerous, as they are presently in a delicate state of balance. A disturbance, natural or man —made, could cause sliding or rockfall activity. Construction on or near unstable slopes can be supported if properly engineered. Such areas, however, will always be more susceptible to environmental catastrophes. Parks or open space recreational uses are preferred on or adjacent to unstable slopes. b. Landslides Where large masses of earth and rock slide bodily down steep slopes, the movement is called a landslide. The rate of movement ranges from very slow to very rapid. The amount of material in the slide can vary from a few cubic yards to millions of cubic yards. Landslides are caused by a change in an unstable slope. Changes can occur naturally through watering and earthquakes, or man —made though changing drainage patterns, creating ponds, and reservoirs. The only potential landslide hazards in the study area are on the southern tip of Baculite Mesa (See Map XVII). .1 :� : --' �,/`' , /rte 1 — / � • .i I,� / •-- •�� ... . _– - .. .. .. .. __. ... /! r' ,� /•, tr •ems �Il GO rj ., r . � ' •' ,., �._ _�.�" i . i ,... -�� i CO) O '(lam .�� z c cl cj in tx r-4 CC LL IL a City of Pueblo Department of Planning & Develop MAP' NORTHEAST QUADRANT ANNEXATION MASTER PLAN XVII - 61 - c. Mud Flows /Debris Fans A mud flow (also called earth flow or debris flow) is a rapid movement of a mass of earthen mud. Mud flows occur chiefly in dry canyons or arroyos in semiarid regions and result from cloudbursts or snowmelt. A debris fan is a deposit of gravel, mud, silt, small rocks, and other substances shaped like a triangle and formed where a watercourse enters a larger valley. Debris fans are closely related to mud flows and are sometimes associated with one another. Building on or in the paths of a mud flow or on a debris fan is extremely hazardous. Mud flows can be unpredictable, and seemingly minor factors can trigger the flow. Moderate mud flow and debris fan hazards are found chiefly in the proximity of the floodplains. The "IMGRID Debris Flow, Mud Flow, and Debris Fan Hazards" Map was generated by the extraction and compilation of soil, geology, intermittent stream, and alluvium data bank components. Areas of concern are indicated on Map XVII. d. Expansive Soils and Rocks Expansive soils and rocks means soils and rocks which contain clay and which expand to a significant degree upon wetting and shrink upon drying. Clay is composed of flat, microscopic plates. Layers of water molecules form between these plates. As more water is added, the water molecules push the clay plates further and further apart. This occurs throughout the clay deposit and causes an increase in the size of volume which in turn creates swelling pressures. When the clay deposits dry out, the reverse is true and the deposits will shrink in size. Building can take place in areas containing swelling clay deposits. Professional soil engineers and engineering geologists should become involved before the design of a structure is complete. Foundation design, water drainage, landscaping, and interior finishes are considerations for all development projects. Swelling soils are common in the study area. Much of the study area's soil ranges from low to high in its expansive properties. Some areas within the Northeast Quadrant have been identified as having very high expansive properties (See Map XVII). e. Ground Subsidence Ground subsidence refers to the downward displacement of surface material. Ground subsidence can occur naturally or by man —made processes, such as: (1) removal of groundwater; (2) addition of water to weak soils; (3) dissolving of certain rock formations by exposure to groundwater flows; and (4) removal of materials by underground mining activities. Much of the Northeast Quadrant has a potential subsidence hazard due to clay and alluvium soils and alluvium geologic formations (See Map XVII). Techniques for mitigating problems caused by subsidence on structures do exist and should be reviewed prior to structural design. — 62 — f. Seismic Effects Seismic effects refer to the degree which an earthquake or an underground nuclear detonation impacts the environment. An earthquake or tremor in an area can increase the possibility of geologic hazard occurrence. Landslides, rockfalls, unstable slopes, and flood potential would be greatly affected. These elements were compiled into the number of potential seismic hazards present per cell. Three hazards were identified by the IMGRID Program. In the Northeast Quadrant, the southern tip of Baculite Mesa has the most number of potential seismic hazards present due to potentially unstable slopes, rockfall hazards, and landslide hazards. These hazardous areas should be noted but should not be considered a severe constraint to development (See Map XVII). g. Erosion Erosion is not listed in House Bill 1041; however, the authors of the IMGRID Environmental Analysis felt that the high economic and environmental costs of soil displacement constitutes both a long —range hazard and a resource loss. Erosion is the end — result of a culmination of factors such as vegetative and man —made cover types, gradient, the chemistry makeup of soil, weathering, overgrazing, and other man — caused disturbances. The problem of erosion in the study area ranges from non — existing to severe or losing anywhere from 0 to 200 tons of soil per acre per year. Developers can offset the effects of erosion in most cases through proper preparation prior to construction and through landscape design upon completion of construction. The areas around the Arkansas River and Dry Creek are extremely erosive areas. Developers must utilize the expertise of a soils professional in the design and engineering of any structure in this area. Remedial devices such as check dams, sedimentation ponds, terracing, and rapid planting of bare soil may be required to minimize sedimentation in sensitive areas. Erosion sensitive areas are located within floodplain, drywash floodplain, and debris flow /mudslide hazard areas identified on Map XVII. The City of Pueblo is in the process of amending the Storm Drainage Criteria Manual which will now include the criteria for a required erosion control plan during development. The Manual is expected to be adopted in 1992. h. Radioactivity Radioactivity means a condition related to various types of radiation emitted by natural radioactive minerals that occur in natural deposits of rock, soil, and water. The IMGRID Analysis identified no radioactive hazards in the Northeast Quadrant. However, since the completion of the Analysis in 1977, public awareness of potential radioactivity in the Pueblo region has increased, resulting in additional testing for radioactive materials by property owners. The City of Pueblo does not require testing for radioactivity during development since the City is considered to be low risk. The burden of such testing, if desired, lies with the property owner. — 63 — 4. Mineral Resource Areas Colorado House Bill 1529 (1973) established the policies which most of the local mineral resource plans in the State of Colorado follow. The law declares that the State's commercially extractable mineral deposits are essential to the State's economy, and as such these deposits should be extracted according to a rational plan. House Bill 1529 was followed by House Bill 1041 (1974) which served to reiterate the importance of the State's mineral deposits by describing extractable deposits as "areas of State and local interest." Mineral deposits within Pueblo County have been identified by the Colorado Geological and U. S. Geological Surveys. Deposits of sand and gravel are abundant on Baculite Mesa and other mesas and areas of upland deposits within this study area (See Map XVIII). Prior to extraction of any resources, a thorough analysis must be made of the impacted area. The following must be addressed in this analysis: a. Importance of diverting future developments to areas which will not interfere with extraction of minerals. b. The need to permit extraction or exploration of minerals, unless extraction or exploration would cause significant danger to public health and safety. c. A comparison between the economic value of the minerals present against the economic value of the proposed development. d. Procedures proposed for assuring that exploration and extraction of a mineral shall be carried out in a manner which will cause the least practical environmental disturbance. Permits for extraction and processing of sand and gravel and exploration of natural resources are issued by the County Planning Commission. The only existing extractive mineral resource in the study area is alluvium sand and gravel. The State Highway Department operates two sand and gravel pits on the southern tip of Baculite Mesa (Sec. 3, T20S R64W, Sec. 4, T20S R64W), Nos. 324 and 341. A total of five pits are found in the study area located on Map XIX, and the corresponding status and types are listed below: Special Use Pormit Status Type No. 322 Approved -- 1/24/78 (partially reclaimed) No. 323 Approved -- 1/24/78 (reclaimed /released by MLRB) No. 324 Approved -- 1/24/78 (Reclaimed /not released by MLRB) No. 341 Approved -- 7/23/85 (Active) No. 643 Approved -- 10/27/87 (Active) Extraction /Processing II / II — 64 — ..�.. ,. �. ,.........,�,......,: 111.1.1,- KEY Potential Sand and z Gravel Resources z � / .l 1 t -••I I - f • l - r ' '.

Landfill A landfill and dead animal dumping area is located southeast of the east —west runway at the Pueblo Memorial Airport. This area is on City property and contained within Noise Zone 3. Development within this noise zone is considered "noncompatible" by FAA Standards. Aluminum draws are the only substance in the landfill. These draws are from one of the manufacturing firms of the AIP. This area will remain open indefinitely. It is operated by airport personnel and monitored by the City— County Health Department. The City's abandoned North Side landfill is located within this study area and is bound on the east by the Denver and Rio Grande Western Rail line and Fountain Creek and is adjacent to the I -25 /Eagleridge Boulevard Interchange. This 22 —acre site was closed in 1924 and is owned by the City of Pueblo. Forty— Seventh Street (Eagleridge Boulevard extended east of I -25) is located at the landfill's west border and will eventually cross this site when extended eastward to Jerry Murphy Road. This crossing, including costs and environmental impacts, is discussed in the Northeast Corridor Transportation Plan which was prepared by the City's Department of Planning and Development and approved by the Pueblo Area Council of Governments in June, 1989. This area will remain open indefinitely and is monitored by the Pueblo City— County Health Department. 6. Environmental Composite The Northeast Quadrant is relatively stable. A composite of various environmental factors is graphically depicted of those areas determined to be "environmentally sensitive" (See Map XVII, page 61). These areas will require particular attention in the event of new development. The major environmental constraints in this area are floodplains, landslides, wildfire dangers, mud flows, debris fans, steep slopes, ground subsidence, and expansive soils. Certain constraints such as expansive soils and steep slopes can be mitigated individually through sound engineering practices. However, landslides, ground subsidence, and mud flows are difficult to control and place severe constraint upon development. The areas indicated on Map XVII contain various environmental conditions which could dictate the design and method of development. The degree of sensitivity in these areas is difficult to quantify without more indepth study. Decisions to develop these areas should be preceded by an environmental assessment. — 67 — VI. INFRASTRUCTURE PLANS -- EXISTING AND PROPOSED ROADWAY AND UTILITY SYSTEM PREFACE The existing infrastructure of an area and its ability to expand is crucial in attracting and supporting new growth. Annexation and the subsequent development of new areas, whether residential, commercial, or industrial, will impact the existing infrastructure and will likewise result in the extension of municipal services. This section will describe the existing transportation routes, water and wastewater systems, electric and gas services, telephone services, and cable television systems. An analysis will address the ability of these services to expand and support new development. A. TRANSPORTATION NETWORK The major transportation routes serving the Northeast Quadrant are: 1. Interstate 25, a freeway which serves as the primary north /south roadway in Pueblo and the State; 2. U. S. Highway 50 East, an expressway which serves as the primary east /west roadway in Pueblo and the State; and 3. Colorado Highway 47 which serves as a loop expressway which extends eastward from the intersections of I -25 and U. S. Highway 50 West to serve the University of Southern Colorado (USC) and southward to intersect with U. S. Highway 50 East near the City limit boundary. Other significant roadways serving the Northeast Quadrant are: 1. Jerry Murphy Road, a minor arterial which serves the western Belmont area and the University Park Subdivision. It ties in with Overton Road which serves rural residential and agricultural areas north along Fountain Creek; 2. Bonforte Boulevard, a minor arterial which provides the major north /south access to USC through the Belmont Subdivision; 3. Troy Avenue, a north /south minor arterial which serves the eastern area of Belmont and is also the main eastern access to USC; and 4. Constitution Road, a minor arterial which serves southern Belmont and is proposed as an alternative western access to the AIP. The access alternatives to the AIP which were examined in the Pueblo Airpark Access Alternatives Study are shown on Map VI (page 24). Transportation planning in the City of Pueblo is accomplished with the aid of two transportation studies - - The Analysis District Evaluation to the Year 2010 and The Year 2010 Transportation Plan. The Year 2010 Transportation Plan utilizes computer modeling (TRANPLAN ) and actual vehicle counts to determine the degree of efficiency of the current transportation network. Any deficiencies are analyzed and the effect of alternate roadways are examined. (Proposed transportation corridors in the Year 2010 Transportation Plan are illustrated on Map VIII, page 30). The Analysis District Evaluation To The Year 2010 Plan provides statistics on population, dwelling units, and employment projections for Pueblo County's 139 traffic zones. The Northeast Quadrant examines 17 zones. Table VI. lists the Evaluation's projections, and Map XX illustrates corresponding traffic zones. Most development in this quadrant is expected to occur at moderate rates. Some residential development is expected to occur as "infill" development in certain "Belmont" neighborhoods (Zone 102) and the University Park neighborhood (Zone 137). However, recent proposals since the Analysis District report was formulated will be cause to closely monitor certain areas for potential transportation impacts. These include a new municipal golf course and related residential/ commercial development near the University of Southern Colorado (Zone 103), the annexation of nearly an entire section of land east of USC (Section 16 in Zone 136), and potential development east of Troy Avenue is Zone 101. Additionally, Zone 138 can expect commercial development near the intersections of Colorado Highway 47 and Constitution /William White Boulevard (extended) when this transportation link occurs. The Transportation Network depicted in the Year 2010 Transportation Plan report appears adequate to support these potential growth areas. Updated projections in the Network Analysis report will be formulated when results are obtained from the Bureau of the Census 1990 Census count. In order that future subdivision proposals provide adequate right —of —way and future roadways align into a planned framework, the Northeast Quadrant Three —Mile Annexation Plan, Section IV. of this report, proposes future primary roadway corridors. These corridors are currently being proposed, regardless of immediate need, so that the City's transportation system remains cohesive. — 70 — tttt lilt 1 4et ■l t t l t t t t l t ■t /l.......... t tllll • 1111141111111111 tlllllttt ■ 411 tlt i11111ll4ll1ll4llttt lttllt l- -- r � cq A m �r PC .

WATER SERVICE Pueblo County's water supply flows from snowmelt. The mountain water travels via streams, creeks, groundwater flows, and man —made water systems to the major Eastern Colorado drainage basin of the Arkansas River. Water service within the Northeast Quadrant is currently provided primarily by private wells, the Pueblo West Metropolitan District, and the Board of Water Works - -the primary purveyor of water for the City of Pueblo. The Pueblo Board of Water Works owns part of the Arkansas River flow referred to as "direct flow water rights." By State law, this water must be used at the time of diversion and may not be stored in its raw state. The Board also owns rights to water originating on the Western Slope. This water may be stored. The Board has water rights and storage capacity to support a population of 350,000. Water diverted from the Arkansas River enters the Whitlock Treatment Plant. This plant became operational in 1977. The treatment process employed by the Board of Water Works includes flocculation, sedimentation, and a filtration process. Testing on a continual basis ensures Pueblo of high quality water through rigid quality control methods. The plant has the capability of serving a population of 158,000. There is no further opportunity for expansion at the Whitlock Plant. The Board of Water Works does own a plant site downstream from the Pueblo Dam. If facility expansion was necessary, a "peaking plant" could be constructed on this site. Such a facility would supplement the existing plant during peak summer months and would likely be shut down during winter months. Treated water from the Whitlock Treatment Plant is transferred to the distribution system. This system is divided into pressure zones in order to maintain water pressures within practical limits. The J. 0. Jones, Watts, and Belmont pumping stations serve Northeast Pueblo and the Airport. The J. 0. Jones and Watts storage tanks serve the portion of the City in the 1000 Zone and all of the Airport located partially in the 1000 and 500 Zones. The tanks at Belmont serve the 3000 Zone, and the 5000 Zone and 7000 Zone (the 5000 and 7000 Zones are interconnected) are served by the Belmont stand pipe and by variable speed pumps at J. 0. Jones. The pressure zones are defined by elevation as follows: Zone 500 (east end of the Airport) serves elevations 4500 -4650; Zone 1000 (City and the Central and west end of the Airport) serves elevations 4650 -4750; Zone 3000 serves elevations 4750 -4900; Zone 5000 serves elevations 48870 -5000; and and Zone 7000 (currently interconnected with Zone 5000) will be the area absorbed into Zone 5000 when another tank is constructed in Belmont) serves elevations 4900 -4950 (See Map XXI ). The Board of Water Works has developed rules and regulations for water service outside Corporate limits. Two service areas are identified by Board policies: Service Area "A" and Service Area "B" (See Map XXII). Extraterritorial water applicants, whether in Permit Area A or Area B, must agree to annex to the City when legally eligible. They must agree that such service is to be contingent upon maintaining sufficient service to the City's residents. Once an agreement is signed, the applicant has 120 days in which to act while being guaranteed the established fees. After this time, fees will be adjusted to current levels. The plant water investment fee is charged to customers seeking service through new, additional, or increased size of meter or number of units. The fees are updated regularly and may be obtained from the Board of Water Works. — 74 — I 5000 ZONE Northeast Quadrant north 7000 I ,'3000 ZONE'.

The plant water investment fee is charged to customers seeking service through new, additional, or increased size of meter or number of units. The fees are updated regularly and may be obtained from the Board of Water Works. — 74 — The unit cost structure program allows all water applicants including contractors and developers to install water mains at equitable costs under Board engineering and inspection standards. The Board will credit accounts and projects completed within one year. More information regarding the unit cost program may be obtained from the Board of Water Works. If an applicant requests that the Board install a main extension inside Permit Area A, the applicant will be charged the unit cost per foot of main extension, regardless of size. The cost of asphalt pavement or concrete replacement shall be paid by the developer /customer. It should be noted scheduling of water and no extension of linear feet do not main. In certain additional costs are that the workload of the Board does not allow for early main installation. There is a one —year completion deadline time will be granted. Furthermore, the established costs per refer to the applicant's actual cost to install the water areas, such actual costs may exceed the outlined costs. Any the responsibility of the applicant. In the semiarid Southwest, water is viewed as a limited resource. Individual wells are coming under closer scrutiny by the State's regulatory authorities as to their affect on surface water rights. Subsurface waters in the State are considered to be tributary to surface water rights, unless non — tributary status can be established through the provisions of Senate Bill 213 (1973). If in the application process a proposed new well is found to be tributary, water augmentation may be required. In addition to water augmentation legislation, the importance of community water systems is further substantiated by the considerable cost of tapping a non — tributary aquifer to avoid water augmentation. In Pueblo County, non — tributary aquifers are generally in excess of 800 feet below surface. Neither tributary nor non — tributary wells are assured to produce potable water. Based on these conditions, it can be assumed that most of the future growth in the Pueblo region will be dependent upon community water supply systems. C. WASTEWATER The City of Pueblo Department of Public Works is responsible for the sanitary sewerage and wastewater treatment operations for the City. In 1984, construction began on a new 19 million gallon per day (MGD) high —rate trickling filter/ activated sludge wastewater treatment plant. This treatment plant, located off of Joplin Avenue (State Highway 227), is capable of serving a community of up to 147,900 persons. It began full operation during the summer of 1989. Map XXII illustrates the City of Pueblo's wastewater service boundary. This boundary, which delineates those areas serviceable through the City's gravity flow system, generally follows a ridge contour. Although the areas shown are technically serviceable, sewer lines have not been extended throughout these areas. Capacity limitations within the existing sanitary sewer system may preclude development within the entire service area until such time as the deficiencies are corrected. Development inside this service area simply requires trunk line extension to the development. Outside this area, the cost of line extensions and any necessary lift stations would be the developers. This cost is dependent on the distance and topography separating the development from existing trunk lines within the service boundary. — 77 — Prior to March, 1988, extraterritorial sewer service was provided to applicants with the stipulation that the owner or developer agree, in writing, to consent to annexing to the City of Pueblo when the land became eligible, and that the owner understand that such service could be terminated by the City Manager in order to maintain adequate service to the City of Pueblo. In March of 1988, Ordinance No. 5466 was adopted. This amendment to Section II of Chapter IV, Title XVI of the 1971 Code of Ordinances relating to Extraterritorial Sewer Services, reads: Notwithstanding any other provision of this chapter to the contrary, no land located outside the City of Pueblo or outside the Pueblo Memorial Airport is eligible to receive extraterritorial sewer service, and no application for such service may be filed with or accepted by the City. This subsection (d) is repealed, effective July 1, 1989. Prior to said repeal, the City Council shall review this chapter. When this ordinance was adopted, it was anticipated that if the new treatment plant was in full operation prior to July 1, 1989, this amendment would be repealed; however, for various reasons, the ordinance was extended to July 1, 1990, and subsequently extended to July 1, 1991. Ordinance No. 5690, which was adopted in June, 1991, deletes any reference to an expiration date. Currently, there are no areas in the unincorporated area of the Northeast Quadrant served by extraterritorial City wastewater services. The airport's wastewater treatment facility was constructed in 1942 by the U. S. Army Corps of Engineers, and a trickling filter was added in 1943. Prior to 1977, the performance of the trickling filter did not consistently meet NPDES permit requirements. In 1977, the City of Pueblo upgraded the airport facility by replacing the trickling filter with a rotating biological disc and by installing chlorination basin baffles. The plant was expanded in late 1986 to a new hydraulic flow of 300,000 gpd (average flow), 640,000 gpd peak flow. The expansion included the installation of a second Rotating Biological Contractor (RBC) (100,000 sq. ft.) and the conversion of an unused intermediate clarifier into a chlorine contact chamber. Since the 1986 update, three sewage lift stations were installed in the airport service area. The first lift station, named Sperry, is located near the entrance of the AIP and south of Unysis. It is a duplex system with each pump rated at 800 gpm and serves the western portion of the AIP. The second lift station, named Target, currently serves the Target Distribution Center. In the future, this lift station will serve the area to the northeast of Target. The Target lift station has a duplex system with each pump rated at 251 gpm. A third lift station is located between the County Shops area and the AIP wastewater treatment facility. It was constructed to accommodate a portion of the central area of the AIP that otherwise would not be served by a gravity sewer. It has a duplex system with each pump rated at 302 gpm. It will handle the remaining capacity of the existing treatment facility. In 1987, Pueblo City Council authorized an engineering study of the airport's wastewater treatment needs. In March of 1988, CH2M Hill consultants released the Pueblo Airport Industrial Park Wastewater Treatment Plant Preliminary Engineering Study. - 78 - This report addressed the fact that if the remaining 500 acres of available industrial land at the industrial park is developed, existing wastewater facilities would be unable to process the resulting flow and loading. The engineers began projections based on since current zoning industry, each with di City representatives, developed. their study by establishing five "flow and loading" various development scenarios. This approach was necessary regulations in the study area allow for several types of ffering flows and high strength wastes. In cooperation with five management alternatives to the capacity problem were All of these alternatives involved the abandonment of the existing airport treatment facility. The CH2M Hill engineering study, based on selection criteria, nonmonetary issues, and costs recommended pumping all wastewater back to the City's plant. New sanitary sewer pipeline is currently being installed utilizing airport sales tax funds, with completion scheduled for September, 1992., Upon completion, the airport wastewater treatment plant will be shut down. Two areas in this study area which are not serviced by a wastewater treatment facility are the area north of the existing service areas including the southern tip of Baculite Mesa and an area between the AIP and the east boundary of the City. Wastewater service to these areas may be costly. At this time, the Engineering staff of the City's Public Works Department has not yet determined the construction needs of the areas in question. Septic tank pumpers and haulers which pump out and dispose of septic system and other sewage wastes must abide by City— County Health Department requirements. They must also meet the receiving wastewater treatment plant's applicable conditions or disposal regulations. Pursuant to the Individual Sewage Disposal Systems Act, the Pueblo City— County Health Department is responsible for licensing septic tank pumpers and haulers. The license governs tank capacity, safety, and disposal. It is issued annually but complaints on safety and dumping can result in the revocation of a license.

(This report is detailed in Section II, Annexation Requirements.) If it is discovered that new construction will cause hydraulic deficiencies in the system, commonly referred to as "bottlenecks," then the developer will be required to finance the solution for such deficiencies. As development in and around the City continues, it will be inevitable that the existing line and interceptor systems will be in need of expansion. This is accomplished by laying line parallel to existing trunk lines or by replacing sections of the old system with new and larger lines. — 79 — Developers shall pay a cost of construction for trunk line interceptor extensions and for any lift stations needed. Through an agreement with the City, a portion of the construction cost can be refunded to the developer when new customers tie onto those particular trunk lines. Stormwater disposal systems must also be financed by the developer. Stormwater disposal is provided by a system of drains and lines which are separate from the wastewater system. These lines drain the City area and release stormwater into the Arkansas River. D. ELECTRIC POWER The Northeast Quadrant is provided electric power by WestPlains Energy Corporation (formerly Centel Corportion) (See Map XXIII). WestPlains Energy has a franchise agreement with the City of Pueblo to be the sole provider of electricity within municipal boundaries. WestPlains Energy operates an electrical power generating station at 105 S. Victoria Avenue. Initially, the plant burned coal to generate electric power. The plant currently burns natural gas as its primary fuel and utilizes oil for peaking generation and as a backup in the event of natural gas curtailments. The plant complies with all Environmental Protection Agency requirements. Generation facilities at the plant consist of two units with a capacity of 8,000 kilowatts each; one unit with 19,000 kilowatt capacity; and five diesel generators, each with a capacity of 2,000 kilowatts. WestPlains Energy has two power plants outside the City of Pueblo, one at Canon City and another at Rocky Ford. Together, the three power plants have a total capacity of 106,000 kilowatts. WestPlains Energy purchases approximately 65 percent of its power requirements from Public Service Company of Colorado under a renewable 20 —year contract. WestPlains Energy is a member of the Colorado Power Pool which includes the Public Service Company, the City of Colorado Springs, and the City of Lamar. The power pool provides backup power in the event WestPlains Energy experiences a temporary shutdown of any of its generating units. Most power outages are due to extreme weather conditions and rarely affect the entire City at one time. WestPlains Energy distributes electrical energy throughout the City of Pueblo through its transmission and distribution network. The Northeast Quadrant of the City is served by one distribution substation. This substation is served by several 69,000 and several 115,000 volt electrical transmission lines. The transmission lines are located on utility easements of 120 feet for parallel lines and 100 ft. for single lines. WestPlains Energy officials state that all requests for electrical service in the study area can be fulfilled with reasonable promptness. WestPlains Energy's service policy is found in Section 18 of its rules and regulations manual. The policy states that an applicant's electrical requirements (either for an individual or a developer) are designated by the company to be permanent, indeterminate, or temporary. Distribution system extension costs are estimated on the basis of the anticipated construction and installation costs i/ LW { - - -- it , ''' ,?y o �- _ =' 0 Od x_.115 bV,' ' � � � W � old .... ,W. a s 1-69, "4600 �tlOR - - - . ir• _ a 8 c >u z = = I .. � -- ....� :- } � t� te r, .

An applicant for permanent service is required to pay all distribution extension costs in excess of a construction allowance determined by WestPlains Energy. The construction allowance is determined by the type of service and the customer's estimated electrical power demand. The customer's payment may be partially or totally refunded during a five —year period. After five years, no refunds will be made. Indeterminate and temporary customers are required to pay all distribution extension costs and do not receive refunds unless reclassified as permanent by WestPlains Energy. E. GAS The Public Service Company of Colorado provides gas service to the City of Pueblo and most of the surrounding area. Portions of the unincorporated area of the Northeast Quadrant utilize private propane gas tanks in lieu of Public Service gas. The company has an agreement with the City to be the sole provider of gas within municipality boundaries. Gas is supplied to the Public Service Company by Colorado Interstate Gas (CIG) Company. East Pueblo, including Belmont, is served through two 8 ", 300 lb. /sq. inch (psi) lines. The two lines share a 75 ft. easement from the airport boundary to a substation located between Troy Avenue and Colorado Highway 47. A 20" line traveling in a north /south direction is located east of the airport (See Map XXIII). Easement for this line is 100 ft. The Public Service Company, in its Manual of Rules and Regulations' Extension Policy, claims it does not operate nor does it maintain CIG lines and is therefore not responsible for a continuous flow. The Public Service Company taps into the CIG main pipeline and distributes gas to its service area. Extension of distribution lines for new service is by application. The company will designate an applicant's service needs as either permanent, indeterminate, or temporary. The proposed service installation is analyzed in order to estimate costs of labor, materials, rights —of —way, and any incidental and overhead expenses. This estimate is the construction payment. An application for permanent service will receive a construction allowance. Indeterminate and temporary customers do not receive construction allowances. Distribution lines are installed by the company and paid for by the applicant (less the construction allowance). Construction payments are refundable in part or in their entirety within a five year period, commencing with the extension completion date. When a new customer is added to the line, the customer's share of the construction payment is refunded to the person, or persons, who initially paid for the installation of the distribution line. These refunds are paid on a yearly basis. No refunds are given to temporary or indeterminate customers unless the new applicant is designated for permanent service. The Public Service Company is regulated by the Public Utilities Commission. Policies are subject to periodic change. F. TELEPHONE U. S. West Communications provides local telephone service to the City of Pueblo and to the Northeast Quadrant. The area is served by U. S. West's technical offices in Downtown Pueblo. U. S. West Communications will provide prompt service to all requests in its service area. For most installations, the entire cost is paid for by the developer. Upon the completion of installation and for five years thereafter, the developer will be entitled to refunds of part, or the entirety, of the installa— tion payments. This occurs when new customers use the new distribution lines and when initial construction payments are recalculated to include the new customer. U. S. West prefers to work closely with the developer so as to efficiently serve new customers. Such cooperation facilitates the acquisition of 20 ft. easements for the cables and poles; it also ensures the use of the most appropriate communications system. G. CABLE TELEVISION The Northeast Quadrant is primarily serviced by Telecommunications, Inc. (TCI), Cablevision of Colorado. TCI Cablevision offers cable television hookup and an array of programming packages. At present, most areas outside City limits in the Northeast Quadrant are not serviced by TCI. Company officials cite an insufficient population density as the reason for not expanding into this area. The company requires that considering the extension technicians estimate the t needed to extend service. committee for approval. approximately one year. there be 28 to of services.

S. West telephone poles by application. They are not opposed to installing cable underground and will work with the developer or follow the ordinances of the community in order to install cable in the least obtrusive manner. Costs of installing cable are approximately $5,000 for an aerial mile and $10,000 for a subsurface mile. All construction and installation costs of distribution cables are paid for by the company. Residents who desire the cable services pay for the initial hookup and then pay a monthly service charge. VII. PUBLIC FACILITIES -- EXISTING AND PROPOSED PLANS PREFACE Recreation, education, and public protection are community services which maintain an area's well being, growth, and attractiveness. In turn, growth will increase the use and the demand for public services and facilities. Public facilities must be capable of expanding in order to meet this increased demand and still provide consistent quality and quantity of service. This section will examine the schools, parks, and fire and police facilities and services within the Northeast Quadrant. The impacts caused by development and expansion capabilities will also be discussed. A. SCHOOLS Pueblo County has two public school districts, No. 60 and No. 70. School District No. 60 is primarily contained within the Pueblo City limits; however, it also includes land outside City limits. District boundaries are not precisely the same as City limits in that some "City" children go to "County" schools and vice versa (See Map XXIV). 1. School District No. 60 School District No. 60 is divided into four high school service areas which relate closely to the City's Northeast, Northwest, Southeast, and Southwest Planning Quadrants. District No. 60 maintains a total of four (4) high schools, six (6) middle schools, twenty —three (23) elementary schools, and a continuing education center. The District prefers that its elementary schools be "neighborhood" schools in that they are planned to be located centrally to and within walking distance of the population they serve. School District No. 60 acquires new school sites by working directly with the developer. The School District prefers this method in lieu of land dedication through the Subdivision Process because it allows them to select quality land. Potential future school sites currently exist in the University Park and Belmont Subdivisions. The Northeast portion of the City contains four elementary schools, one middle school, and one high school (See Map XXIV). Table VII shows current enrollment, projected enrollment for the 1991 -92 school year, maximum capacity, and optimal capacity for each of the schools. According to these figures, Franklin and Haaff Elementary and Heaton Middle Schools have surpassed optimal capacity and nearing actual school capacity. All other schools in the area can accommodate increased enrollment growth. - 86 - TABLE VII: SCHOOL DISTRICT NO. 60 ENROLLMENT -- MAXIMUM OPTIMAL CAPACITIES SCHOOL 10/1/91 ENROLLMENT PROJECTION 1991 -1992 MAXIMUM CAPACITY OPTIMAL 90% CAPACITY ELEMENTARY South Mesa 403 700 Vineland Belmont 511 522 505 455 Eastwood 234 263 225 203 Franklin 451 449 500 450 Haaff 363 355 375 338 MIDDLE SCHOOL Heaton 765 793 750 675 HIGH SCHOOL East High 1,257 1,236 1,943 1,749 SOURCE: School District No. 60, Office of Pupil Personnel. ^Includes Jump Start children. 2. School District No. 70 School District No. 70 has four elementary schools -- Baxter, North Mesa, South Mesa, and Vineland - -whose service areas incorporate the Northeast Quadrant. Baxter Elementary is presently closed but would be reopened if residential growth warranted such action. Two middle schools and one high school service the area. All of these schools are below their maximum capacity (See Map XXIV and Table VIII).

Approximately 94 percent of the students are bussed to schools. Although it is a rural school district, School District No. 70 identifies philosophically with neighborhood schools and additional facilities would be constructed to meet the demands of growth and development if deemed necessary in an area. School District No. 70, through an agreement with Pueblo County, requires that ten percent of net land in residential developments be dedicated for school sites or that fees be paid to the district in lieu of land dedication. School officials estimate that 10 -15 acres are needed for an elementary school, 20 -25 for a middle school, and 35 -40 acres for a high school. 3. Detachment and Annexation of School Districts Detachment and annexation of territory from one district to another is a complex process. The School District Organization Act of 1965, Section 22 -30 -138, states that if detachment and annexation is deemed to be worthwhile, then both boards of education must adopt a resolution to change the boundaries of their respective districts. This resolution then goes to a joint committee or to the District 70 superintendent for approval. Once this is done, a special election is held in the territory proposed to be detached. If five or fewer registered voters reside within the territory proposed to be detached and annexed, a notarized statement of consent of all voters within the territory shall make it unnecessary to hold an election. In the absence of said statements, an election must be held. If there are no registered voters within the territory, no election is to be held; and the joint committee or District 70 superintendent shall approve the proposed detachment and annexation of the territory. Such detachment and annexation of territory brings to issue not only student welfare but district assets, liabilities, revenues, and influence. It should not be assumed that Districts 60 and 70 would change their boundaries when land is annexed to the City. B. RECREATION 1. Parks and Recreation The City of Pueblo has approximately 948 acres of parkland and 1,707 acres of open space floodplain within its boundaries. Combined, these account for more than ten percent of total City land. Recreational facilities include a large urban park (City Park) which serves the entire Pueblo community, a district park (Mineral Palace) which serves a portion of the City, and smaller parks which serve neighborhood populations. Parks and recreational land standards are expressed in terms of a given number of acres per unit of population. Those quantitative standards observed by the City Department of Planning and Development are as shown in Table IX. TABLE IX: PARK STANDARDS DESCRIPTION SERVICE AREA DESIRABLE SIZE POPULATION Urban Park: 30 Minutes 200 Acre Min. 2.5 Ac /1,000 District Park: 1 -2 Miles 25 Acre Min. 5.0 Ac /1,000 School Parks /Playgrounds: 112 Mile 2 -25 Acre Min. 4.0 Ac /1,000 Neighborhood Park: 1 -112 Miles 5 Acre Min. 2.5 Ac /1,000 Special Use Facilities: Areas which are designated for one single purpose. Urban Plaza /Streetscape: Open space in urban core offering sidewalks, seating, and landscaping. Parkways /Medians: Landscaped thoroughfares which provide visual relief and natural beauty; they are of considerable value in the implementation of a recreational trails system. Recreational Trails System: A non — motorized trail of varying width (minimum of eight feet) and length. It is designed to weave through existing natural /scenic and urban areas, thus connecting and offering better utilization by recreational and non — recreational users. As a home rule city, the City of Pueblo has the authority to own and maintain property for public purposes. Parkland areas may be acquired through City purchase, property gifts, through settlement of delinquent taxes, abandonment, easements, and through land dedication. Title XII, Chapter 4, Section 7(e) of the City Code of Ordinances, states that eight percent of land subdivided for residential purposes (exclusive of street widths) is to be dedicated as parkland. This land can be several small parks or one large park depending on the needs of the community. If the City Council determines that said land is not appropriate for parkland dedication, the Council shall require a cash payment in lieu of land dedication. This payment shall be equal to eight percent of the fair market value of the land in such subdivisions. This payment is deposited into a special fund to meet future recreational needs in the City. The City Parks and Recreation Department is responsible for the development, operation, and maintenance of recreational and park facilities. The City Department of Planning and Development provides professional planning and landscape design services when needed. Financing new parks and recreational development is provided through the City's General Fund. The dollars generated by the Colorado Lottery are deposited into the General Fund and earmarked for "allowable" parks and recreation projects. Funding is supplemented with State and Federal grants. Presently, the Northeast Quadrant has 100.34 acres of recreational land (excluding the new WalkingStick golf course which officially opened July 1, 1991) (See Map XXVI and Table X). The Northeast Quadrant Study area has an estimated population of 14,965 with approximately 14,552 within City limits (City Information Department estimates for 1985 from 1980 Census Tracts). Currently, this population is not in need of a district park by the quantitative standards; however, build —out of several proposed residential areas will create a demand for such a park. City Parks and Recreation officials however have been researching potential future locations for a larger park. Approximately 80 acres in the floodplain at the Fountain Creek, between the Creek and the University Park Subdivision, is the most obvious choice for a district park. The land is currently owned by the City and offers room for playing fields, courts, parking, and picnicking. This proposed park (indicated on Map XXV) would be an ideal northern access point to the Pueblo trails system. The City Parks and Recreation Department recommends the development of a regional park in the Northeast Quadrant. This park would be a minimum of 200 acres and would serve the Northeast Quadrant. It could include lighted fields and courts, a concessions area, rest rooms, ample parking, and a large recreation complex. League sports and evening activities could be concentrated here, away from the City residential areas. It is envisioned that this park be developed adjacent to the environmentally sensitive lands of Baculite Mesa nd nearby creeks and arroyos. The City, utilizing reclaimed sand and gravel pits, could then offer sports areas and areas with varied terrain. The multi —use trail should extend to this park, wind through natural areas, and explore scenic vistas. It is unlikely that such a large area would be donated to the City in full. The land would, most probably, have to be purchased. Officials at the City of Pueblo's Parks and Recreation Department would like to continue the development of parks and trails, taking precautions to develop a park system based on quality of design and on offering of a variety of recreational opportunities. 2. Recreational Trails System The Pueblo River Trails System consists of non — motorized trails available for bicyclists, pedestrians, horses, and other non — motorized recreationalists. Trails in the City are generally 8 ft. wide and constructed of asphalt or concrete. Trails flank the Arkansas River to the Reservoir and the Fountain Creek. Other paths are located along sections of Wildhorse Creek, State Highway 78, Northern Avenue, Pueblo Boulevard, State Highway 47, U. S. Highway 50 Bypass, and near the University of Southern Colorado. It is desirable to plan for multipurpose trails in order that proper rights —of —way be reserved and that a logical network can be constructed. Trails in the study area should take advantage of the Arkansas River, rural areas, proposed parks, and principal roadways. They should link existing recreational facilities with natural settings and other public facilities. .I '� y d ®IFIRPME Ro. _ n•�rr � "� I �t S / r JJ • J YS O,S N[110N N 4Dlt �® NrJ °M1ON ° yJ fNr pa3 K 1 I 1"�l S M• •RI t 7i 3 • I .t ' DIIION Olt Proposed Park t •' J s ® f:.

The Pueblo Bicycle System and Trails Plan was completed in 1990 by the City of Pueblo Department of Planning and Development. This plan examines the existing trails system and proposes logical extensions of the system. The plan also examines the trails design, construction factors, and safety. The goal of the plan is to set forth policies aimed at the construction of a trails system which will serve Pueblo in an efficient, safe, and quality manner. The Pueblo County Department of Planning and Development has outlined a conceptual plan for a river trails recreational system. This plan would include a multi- purpose trail south of the river, linking small parks, the Airport, and the St. Charles Mesa communities. The County Department will research the possibility of acquiring land which was previously used for mineral extraction activities. These areas, once reclaimed, could be developed as recreational, picnic, and trail access areas. - 92 - C. FIRE 1. Citv Fire Department The Pueblo City Fire Department provides standard fire protection to the City of Pueblo. The Department employs 134 fire fighters and three administrative assistants and operates nine fire stations. Operating and improvement costs are budgeted by the City. The City is divided into eight fire protection zones and one zone at the Pueblo Memorial Airport. Each is served by a fully equipped fire station. Four stations serve the Northeast area of the City (See Map XXVI). They are: Station No. 6, located at 1335 E. Fourth Street, is equipped with the same type truck and is operated by three, three — person shifts. Station No. 8, located at 1515 Bonforte Boulevard, is operated by three, three — person sifts and is equipped with a three —way pumper truck. By Fire Department standards, a station should be central to its service area with no point further than one and one —half miles away. It is ideal to have a maximum response time of four and one —half to five minutes to any point in the service area. Roadways, accessibility, and the number and density of houses are all factors contributing to new fire station locations. University Park is not within one and one —half miles from any City fire station. Station No. 8 is presently serving the area. Land in University Park has been deeded to the City Fire Department; however, a definite time schedule for development of the station has not been determined. Once an area is annexed into the City, the City Fire Department becomes responsible for fire protection in the area. In the event that a new station was needed, the Fire Department would apply for special funding from City Council. A new fire station, utilities, a new pumper truck, equipment, and fire fighter salaries (three shifts and backup personnel) would initially amount to $861,000 (1989 dollars). Annual operation costs would be approximately $400,000 (1989 dollars). The City Fire Department has a hazardous materials response team ( "Haz —Mat Team ") located at Station No. 4 at 1201 E. Evans Avenue. This crew is specially trained and equipped to contain hazardous material (chemicals, radioactive material, and some waste products) accidents. They will respond to accidents outside the City limits. 2. Pueblo Memorial Airport The Pueblo Memorial Airport is staffed 24 hours a day by two people and is equipped with a three —way pumper truck and two crash trucks complete with foam and powder fire retardants to control fuel fires. The responsibility of the station is to provide protection to the terminal facility, to air —side (landing zones, taxiways, ramps, hangars, etc.) emergencies, and also to the AIP. — 93 — - 94 - The Department of Public Safety and Operations (previously Civil Defense) is located at the airport. In the case of any peace time accident -- natural or man— made -- including nuclear accidents, the staff of four and a trained volunteer response team of 20 to 30 persons will assist in the planning, mitigation, preparation, and exercising of disaster plans. They respond County —wide and have vehicles, medical supplies, tools, and other emergency equipment. 3. Unincorporated Area The unincorporated area of the Northeast Quadrant does not have fire protection. The County Sheriff's Department will respond to rangeland fires only. The crew for rangeland fires consists of volunteers, not certified sheriff deputies. The Department has one tanker truck. 4. Summary Long —range expansion plans for the Pueblo City Fire Department are dependent upon the location of new development. Development plans for proposed annexations will be reviewed in relation to new road construction, number of existing and new buildings, density of buildings, and other factors which may affect response time. Priority for the Fire Department is the construction of a new station in University Park. D. POLICE 1. City Police Department The Pueblo City Police Department is operations are headquartered from this Department employs 171 authorized sworn vehicles. The City is divided into 24 hours a day in three shifts. The $207,500, including three, one — person automobile expenses and repairs (1989 Dol located at 130 Central Main Street. All location. There are no substations. The officers and maintains an array of patrol ten beats, or routes, which are patrolled annual cost for one beat is approximately shifts of officers, backup personnel, and lars). All areas within Pueblo County (incorporated and unincorporated) are within the jurisdiction of the County Sheriff. However, when land is annexed to the City, the Police Department assumes primary protection of that area. There are no specific standards for instituting a new patrol route. If the department has a concern for an area as to the amount of protection needed, a study will be organized by the department. This inquiry will examine the level, type, and density of development, the employment sources, and the employee and consumer generating sources. Business and commercial development requires higher levels of protection than does strictly residential development. The sources of employment, employees, and consumers will indicate to the Department if activity is new to the Pueblo area or merely a shift from another area. The decision to create a new beat will be based on the City Police Department study. — 95 — The City Police Department is presently responsible for protection of the airport and AIP. A uniformed police officer must be present for all departing flights. These duties are provided for by a special operations section. Airport and AIP protection is detailed in the "Airport" Section. Long —term plans of the Police Department are dependent upon growth and development - -where it takes place and what economic, social, and political changes occur. Officials envision an expansion of the Northeast beat, a separate beat to include the airport and surrounding development, and a permanent position to perform airport duties. 2. County Sheriff Department The County sheriff deputies patrol all areas outside the City, with the exception of the airport and AIP. The County sheriff deputies frequently patrol the Belle Plain area, the Transportation Test Center east of the airport, and the Baxter area to the south. The County sheriff deputies do not regularly patrol the open rangeland. Upon annexation, police protection responsibility transfers from the County Sheriff Department to the Pueblo City Police Department. VIII. CURRENT ZONING AND LAND USE PREFACE Current land uses within this study area reflect zoning patterns that are based on historical trends. The predominately single— family housing areas of Belmont and University Park within City boundaries reflect residential and commercial trends. The Belle Plain area and the airport industrial park reflect City and County economic developments of a different scope. Potential land uses are proposed in Section IV, the Three —Mile Annexation Plan. A. CITY ZONING The Northeast portion of the City is designated primarily as single — family residential with commercial zoning located at the intersection of Bonforte Boulevard and U. S. Highway 50. Two large single — family residential subdivisions and the University of Southern Colorado have been established within the City boundaries. University Park Subdivision is residentially zoned with commercial uses bordering Colorado Highway 47. Agricultural, open space, light industrial, and pockets of commercial zoning lie to the north along the I -25 Corridor (See Map XXVII). The University of Southern Colorado is zoned for public use, yet is bordered by adjacent and developed commercial, single — family, and multifamily residential properties. B. COUNTY ZONING The majority of County land in the study area is zoned A -1, indicating a range type agricultural use. Rural residential and a small pocket of industrially zoned land is located in the northwestern corner of the study area. Heavy industrial zoning follows the U. S. Highway 50 Corridor. The Pueblo Memorial Airport, owned by the City of Pueblo, is zoned as public land. The airport industrial park is zoned for light industrial uses, with pockets of public land dedicated for drainage purposes (See Map XXVIII). C. LAND USES 1. General Land uses in the Northeast Quadrant are primarily urban residential within the Corporate City limits and rural residential and agricultural in the remainder of of the study area. The majority of the land in the unincorporated portion of the quadrant serves as open rangeland. The Pueblo Memorial Airport and industrial park is also within the quadrant and is addressed under Sections III and IV of this study. — 97 — t a-1 t - 2 8 �L, ] north -3 -- _ -� , 1 �.a 1 �o-1 1 \ R_4 11 2 R-1 S - 3 � yERStTr I CGUIJTY ! � 0-1 J + 6 -3 R-5 + S -1 • R-2 ., R -1 - I� .� ,.RF 4 o.

Belle Plain Belle Plain is located to the immediate north of U. S. Highway 50 and to the east of Colorado Highway 47 (See Map XXIX). Several large auto salvage operations and some residential development are found on land that is zoned Industrial, Category 3. The I -3 zoning allows all heavy industrial uses as a use —by —right except hazardous waste facilities. Residential uses here include housing for caretakers and security, some nonconforming residences (those not allowed by zoning ordinances, but having been established before such zones were designated in 1963), and vacant older homes. Water and sewer are provided by private cisterns and septic tanks. County Zoning I -3 has no requirements for the landscaping or screening of industrial grounds. The City, however, requires that salvage yards be completely enclosed by a 7 ft. fence of masonry, wood, or ornamental hedge. No stacked vehicles may be visible above the screen, and the operation shall not encroach upon or utilize any areas outside the salvage yards (Title 9, Chapter 7). 3. Farmland The economy of Pueblo County is partially based on the farming and ranching industry. The U. S. Department of Agriculture (USDA), Soil Conservation Service, is charged with the responsibility of identifying and locating prime and unique farmlands. This important farmland program encourages the identification of farmlands of Statewide and local importance. A minimal amount of the open rangeland in the Northeast Quadrant is classified as "Prime Farmland If Irrigated" by the USDA Soil Conservation Service (See Map XXX). The high cost of irrigation to most of the Northeast Quadrant is a deterrent to large —scale farming in the study area. Therefore, most of the agricultural use in this quadrant is devoted to open rangeland. D. LAND OWNERSHIP Most of the land in the unincorporated portions of the study area is divided into 20 acre parcels or larger. One landowner possesses thousands of acres to the north and east of the airport. Smaller parcels and subdivisions are found along the City boundary. Parcel sizes will be analyzed in the event of an annexation impact on road and utility line extension decisions (See Map XXXI). — 100 — MAP KEY: i r W oo h Auto Salvage or Storage (I -3 Zoned) 1QDE HOOD s , r �.... 4 ♦ J I� s IW I �Q r I/ F l ` N north 1 1 1 4 $ I y Q 4 � f �� —N / J IE RI 1 I G p b i 3- A �z I 'RNQWVILI�`` j • • tikgY S o City of Pueblo Department of Planning & Development NORTHEAST QUADRANT ANNEXATION MASTER PLAN w a x Go A z a a w a a MAP: XXIX - 101 - e fe e /I Y1 I \„ 1,1 }(1111111 111I��U111 �adAAl.��)Ll' II.1..._ ��•�'„ y , ,{� r { t 1, •' /, f" ; Al .� 1 _� ,Y ' : �{ � , s' V��, i % %Yip;.. � _ __ • If . t,•,• 1, : ww�''1,� 'Jm�'1,�� &4'',: {_ : 1 �ia� R, f�. r r r, ��h: , • )) ..�' : ''alr •, .bA '► 'fie • %r� //� ,� 4 1 W ! p' .•.
