PURPOSE The Southwest Quadrant Annexation Master Plan is in response to the Municipal C 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 C 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 r development decisions should be made according to criteria that best suits the l� overall goals of the City. The Southwest portion of the City consists primarily of newer residential subdivisions including E1 Camino, La Vista Hills, Regency Park, and Sunset Park Subdivisions. Recent development proposals indicate that this residential trend will continue both south and west of current City boundaries. The Southwest Quadrant Annexation Master Plan Update addresses this potential growth trend. The purpose of the plan is to establish specific guidelines and recommend policy which would ensure that annexation and development is consistent and compatible with existing land uses, with City land use and transportation policies, and with State annexation statutes. B. OBJECTIVE C This annexation master plan the Southwest Quadrant. C Comprehensive Development P be used to identify proposed extension area" within the will serve as the official "three —mile area plan" for It does not supersede the 1980 Pueblo Regional Ian except insofar as the Three —Mile Area Plan shall land uses in that area defined as the "proposed urban Southwest Quadrant. It is designed to be a framework for development, with sufficient flexibility to be changed as conditions warrant. The goals of the Southwest Quadrant Plan Update are: GOAL 1 : Establish appropriate land use and annexation policies which will guide development within the Southwest Quadrant. These policies will provide a standard approach for future annexations and will supplement City zoning and subdivision regulations. r GOAL 2 : Comply with State annexation laws and Pueblo Board of Water Works policies. GOAL 3 : Identify proposed public facilities, utilities, and land uses within the Southwest 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 purposes of this plan, the following assumptions are made: 1. Development at the Pueblo Memorial Airport Industrial Park will continue at or near its historic rate, and will create the need and desire for new housing. 2. The transportation network will be in need of expansion in conjunction with new development in the Southwest Quadrant. 3. There will be a continuing need for recreational areas (i.e., parks, rest stops, and natural and bike trails). 4. The extension of City water and wastewater services, utilities, and public facilities will be pursued for new development at or near City boundaries. D. LOCATION The Southwest Quadrant Annexation Master Plan study area contains approximately 38 square miles and encompasses an area which extends three miles from the existing City limit line adjoining the Southwest portion of Pueblo, Colorado. The Southwest Quadrant Annexation Master Plan study area is that area bound on the south by Salt Creek and St. Charles Reservoir No. 3, on the east by Interstate 25 and Prairie Avenue, on the north by the Arkansas River and Pueblo Reservoir State Park boundary, and on the west by a north /south boundary line running between Sections 13 and 14 of Township 21 South, Range 66 West (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" shall indicate that area which is considered to be the most probable for annexation due to the ability to extend municipal service into the area (See Map II). —2— ' I Awl t■u t■n o iii i ii on.

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 I 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 C contiguity with the annexing municipality. Contiguity may be established by the annexation of one or more parcels in a series completed simultaneously and considered together for purposes of public hearing requirements. Contiguity shall not be 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 or area, 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 such limit 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 Southwest Quadrant which is within an enterprise zone is depicted in Map III. 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— 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— C C C 11 r C 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 will use 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 as follow: 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 Southwest 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 — 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; C C 11 r C 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 will use 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 as follow: 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 Southwest 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.

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. Any associated impact 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 impact 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 but within the sewer drainage basin, the Sewer Participation Cost Recovery Agreement shall include provisions for reimbursement. 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. (2) Any sanitary sewer impact shall be computed for the entire sewer drainage basin including the proposed development or annexation. Mains shall be designed to accommodate the area as per criteria contained herein. (3) The report shall include an analysis of the existing sanitary sewerage system addressing the impact of additional flows, including but not limited to: (a) the location of all points on the City's existing sewer system where the new system will connect; (b) the identification of hydraulic deficiencies in the system caused by the development (these deficiencies will have been identified by the City during an initial meeting with the developer); (c) a discussion of any pumping stations, force mains, packaged treatment plants, and other special equipment as needed; (d) any proposed corrections, improvements, or upgrading to relieve the existing impacted system; and (e) the financing and scheduling of corrections, improvements, or upgrading to relieve the existing system, including any Private Sewer Agreements that may be proposed. — 9 — (4) The report shall discuss and analyze areas upstream of the annexation site, within the gravity drainage basin, that would impact a trunk line within the site. (5) The report shall identify on a United States Geological Survey (USGS) Map - -Scale 1 to 24,000 - -the gravity drainage basin or basins incorporating the proposed annexation site and the service boundary for the City's wastewater treatment plant. b. Design Criteria for Sanitary Sewers (1) Design of sanitary sewers shall be in accordance with the minimum design standards and specifications for subdivisions of the City of Pueblo, Colorado. (2) Sewer lines shall be designed to flow at less than their capacity. Lines 15" or less shall have a design capacity of 50 percent of the pipe depth. Lines 18" or larger shall have a design capacity of 75 percent of the pipe depth. (3) Flow Factors - -Peak — Single— Family Residential -- 0.0042 cfs per acre — Multiple — Family Residential -- 0.0009 cfs per unit — Commercial -- 0.0040 cfs per acre — Industrial -- 0.0051 cfs per acre — High —Water Consuming Industries -- Special Study Required — Institutional Use -- Special Study Required — Areas Outside the Development Plan -- 0.0044 cfs per acre — Average Infiltration /Inflow -- 0.0003 cfs per acre (4) Areas with a high potential for groundwater infiltration shall be identified. These areas shall be designed to allow an infiltration /inflow (I /I) in accordance with Article 13, "Specifications for Sanitary Sewers." Due to rapid conditional changes, the Department of Public Works shall not be committed to any reported sewer capacities until the property has been legally subdivided. The information in the Sanitary Sewer Report may need to be updated and amended during subdivision procedures. 4. Transportation Plan A Transportation Plan shall be submitted by the Petitioner in accordance with the following criteria and outline specified by the City Traffic Engineer.

IMGRID Analysis The IMGRID (Improved Grid) Analysis was prepared in 1977 and determined, by computer analysis and mapping, the geographic location of natural hazards and resources in Pueblo County, Colorado. The analysis was designed to address the concerns described in Footnote 37 of Senate Bill 468 (1975) as Pertinent Matters and includes: a. Floodplain Hazards; b. Wildfire Hazards; — 15 — C. Geologic Hazards (1) Expansive Soils and Rocks (2) Unstable Slopes (3) Radioactivity (4) Rockfalls (5) Landslides (6) Avalanches (7) Mud Flows /Debris Fans (8) Ground Subsidence (9) Seismic Effects 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: 208 Plan Update, 1987. These plans analyzed the main water sources, both ground and surface, for Pueblo County. Wastewater facilities were examined; point and non —point pollution sources were assessed; methodology and results of water tests were documented; and stream segments were analyzed. Surface watercourses included: 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 reviewed 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 located bedrock formations and surficial deposits in Pueblo County. The bulletin also identified general characteristics and engineering concerns for each geologic member. 4. Waterlogging in an Alluvial Aquifer Near Lake Minnequa Waterlogging in an Alluvial Aquifer Near Lake Minnequa, Pueblo, Colorado by Patrick J. Emmons, is an investigative report prepared in 1976 by the United States Geological Survey in cooperation with the City of Pueblo. The purpose of this report was to determine the cause of the shallow water table south of Lake Minnequa and to determine possible alternatives for eliminating the problem of waterlogged land. The study concluded that the unnaturally high level of Lake Minnequa is the principal cause of the shallow water table. Secondary causes include a bedrock hill east of Lake Minnequa and seepage from the St. Charles reservoirs and nearby drainage ditches. The alternatives suggested by the report to mitigate developmental constraints in such areas are: a. lower the level of Lake Minnequa; b. install dewatering wells; C. install drainage system; d. raise the land surface; e. dredge Lake Minnequa; f. apply restrictive zoning; and g. purchase the waterlogged areas 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 (PRPC ) 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. - 17 - 2. 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 improvements and construction by the Board in its continuing program of water distribution. Its purpose was 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. Water demand estimates and predicted distribution deriiands on the system was also analyzed. In addition, 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. 3. Sanitary Sewerage and Wastewater Treatment Facilities The Sanitary Sewerage and Wastewater Treatment Facilities engineering report was prepared in 1971 by Sellards and Grigg, Inc. The report presents a study of the City's sanitary sewage and wastewater treatment facilities. Proposals for additions and corrections to the existing system are 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 this report includes 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 and recommended improvements to correct present 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 I4WTP will accommodate the sanitary sewer needs in Pueblo to the Year 2004. The City of Pueblo's Department of Public Works is responsible for updating the S &G report. 4. City of Pueblo Urban Parks and Recreation Recovery Action Proqram The City of Pueblo Urban Parks and Recreation Recovery Action Program ( UPARR) document 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. — 18 — 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. C. TRANSPORTATION 1. 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 eleven (11) analysis districts. Each zone was then examined as to its degree of developable land, stability of the environment, activity type (residential, commercial, or industrial), predominant age of structures, and historical change in population; population predictions were then assigned a share of the expected change. The traffic zones were analyzed as to their future growth and transportation needs. Information pertinent to the Southwest Quadrant has been included in the "Transportation Network" section of this report. 2. Pueblo Urban Area Year 2010 Transportation Plan The Pueblo Urban Area Year 2010 Transportation Plan report, which was adopted in 1989 and published in January, 1990, was prepared by the Pueblo Area Council of Governments' UTPD, Colorado Department of Highways' Division of Transportation Planning, in cooperation 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. 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. — 19 — b. To identify transportation system needs compatible with revised projections of development in the Pueblo urbanized area through the Year 2010; and c. To perform a system level evaluation of the social, economic, and environmental impact of alternative land use and transportation plans. In the Southwest Quadrant, the Year 2010 Transportation Plan report identifies the extension of Bandera Boulevard north to Goodnight Avenue and south and east to I -25, the extension of Prairie Avenue and Hollywood Drive to the proposed Bandera Boulevard, and the construction of a new roadway between Red Creek Springs Road to LaVista Hills Road (See Map IV). This Update, and the Year 2010 Plan which was completed in 1989 and published in January, 1990, are statements of present policy toward future needs. The Year 2010 Plan 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 data was based on projected dwelling units and employment. This data was loaded onto collectors, minor arterials, principal arterials, expressways, and freeways. The system was then analyzed for deficiencies. — 20 — "Am City of Pueblo Department of Planning & Development SOUTHWEST QUADRANT ANNEXATION MASTER PLAN MAP: IV - 21 - north ;2; --j r ... ............ ...! . ...... 14 134 . . .........

THE SOUTHWEST 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 Airport Industrial Park (AIP). Recent annexation and development proposals indicate that a substantial portion of new residential construction will occur in the Southwest 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 Southwest 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 that result 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). This 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 area plan" for the Southwest 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 Southwest Quadrant. The Three -Mile Plan shall be used to provide guidance in the review of development proposals and in the negotiation of annexation agreements. The boundaries of this study area extend three riles west and south 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 Southwest Quadrant in which municipal services could logically be extended (See flap II); and - 23 - (2) the rural remainder of the study area which will not be master planned. 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 Southwest Quadrant are intended to provide a transporta— tion 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 is based on a minimum of one —mile spacing between the major transporta— tion corridors' standards. The exact locations of these corridors have not yet been determined, and Map V is intended only to offer a simulated graphic depiction of the proposed transportation pattern of the Southwest Quadrant. In addition, Map V also delineates those roadways identified in The Year 2010 Transportation Plan report (existing conditions) from those roadways that are long —range planning (proposed) corridors. The existing major east /west transportation corridors in the Southwest Quadrant's proposed urban extension area are State Highways 78 and 96. No principal north/ south arterials exist in the proposed urban extension area. Transportation corridors and facilities which are proposed for the Southwest Quadrant include: 1. East /West Corridors a. The western extension of Lehigh Avenue from Kingsroyal Boulevard to proposed Purcell Boulevard (Collector). b. An unnamed road from State Highway 78 to proposed Purcell Boulevard (Collector). c. The western extension of Bridle Trail to proposed Purcell Boulevard and the eastern extension from Encino Drive to Alhambra Drive (Collector). d. Capital Avenue from the I -25 frontage road to Purcell Boulevard (Minor Arterial). e. Purcell Boulevard from I -25 to State Highway 78 (Expressway). f. Realignment of the I -25 frontage road to Prairie Avenue. —24— 25 2. North /South Corridors a. The southern extension of Beulah Avenue to the proposed realigned I -25 frontage road (Minor Arterial). b. The southern extension of Prairie Avenue to proposed Purcell Boulevard (Principal Arterial). c. The southern extension of Hollywood Drive to proposed Purcell Boulevard (Minor Arterial). d. The southern extension of Vinewood Lane to proposed Purcell Boulevard, connecting Vinewood Lane to Burnt Mill Road (Collector). e. The southern extension of Encino Drive to proposed Purcell Boulevard (Collector). f. Bandera Boulevard south from State Highway 96 to proposed Purcell Boulevard (Principal Arterial). g. The northern extension of Kingsroyal Boulevard to proposed Bandera Boulevard and the southern extension to a proposed unnamed east /west road (Minor Arterial). h. The southern extension of McCarthy Boulevard to meet existing Westmoor Drive at State Highway 78, continuing through to proposed Capital Avenue (Collector). i. Purcell Boulevard south from State Highway 96 to meet proposed east /west Purcell Boulevard at State Highway 78, serving as a major transportation loop (Expressway). Major grade separated intersections will be necessary at points where State Highway 78 crosses Purcell Boulevard, at the unnamed east /west collector where State Highway 96 crosses Purcell Boulevard, and at the point where Purcell Boulevard intersects with I -25. Capital Avenue will intersect with the I -25 frontage road. 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 Purcell and Bandera Boulevards. 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 should be strictly controlled as per the Colorado State Highway Access Code The two opposing lanes — 26 — 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 minimum of 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 Southwest Quadrant (more specifically, the proposed urban extension area) 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 that the proposed urban extension area of the Southwest Quadrant will experience a majority of the residential growth in Pueblo. It is the intent of the community and of this plan that diverse housing opportunities are maintained (See Map VI). Rural— residential development (one to five acres) should be encouraged in the northeast portion of the proposed urban extension area and is the preferred residential use in areas adjacent to the sensitive slopes south of the Arkansas River. In addition, rural — residential development shall be permitted on slopes of 20 percent or greater if submitted with appropriate geology and soils tests that support little or no on —site or off —site hazards which will result due to this development. Mobile home parks and subdivisions shall be permitted where currently in existence. Expansion of the parks and subdivisions should be closely monitored and allowed only when opaque screening and appropriate roadway noise buffers are provided. Additional mobile home parks and subdivisions should be allowed in those areas suitable for medium — density, urban — residential use. 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 which 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. — 27 — - 28 - TABLE I: DESIGN NOISE LEVEL /LAND USE RELATIONSHIPS LAND USE DESIGN NOISE CATEGORY LEVEL IN Leq DESCRIPTION OF LAND USE CATEGORY 57 dBA A (Exterior) Tracts of lands in which serenity and quiet are of extraordinary significance and serve an important public need, and where the preservation of those qualities is essential if the area is to continue to serve its intended purpose. Such areas could include amphitheaters, particular parks or portions of parks, or open spaces which are dedicated or recognized by appropriate local officials for activities requiring special qualities of serenity and quiet. 67 dBA B (Exterior) Residences, motels, hotels, public meeting rooms, schools, churches, libraries, hospitals, picnic areas, playgrounds, active sports areas, and parks. 72 dBA C (Exterior) Developed lands, properties, or activities not included in Categories "A" and "B" above. D -- dBA For requirements on undeveloped lands, see paragraphs Ila and c of FHPM 7 -7 -3.# 52 dBA E ## (Interior) Residences, motels, public meeting rooms, schools, churches, libraries, hospitals, and auditoriums. Federal -Aid Highway Program Manual (FHPM), Federal Highway Administration, Volume 7, Chapter 7, Section 3. See paragraphs 8c, d, and e of FHPM 7 -7 -3 for method of application. - 29 - 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. Commercial land uses at the intersections of major transportation corridors should be encouraged in lieu of strip commercial development. Clustering of subregional and highway commercial uses should be promoted at the intersections depicted as commercial nodes on Map VI. Small segments of strip commercial development shall be permitted along State Highways 78 and 96, where currently existing, and in areas where they will serve as a buffer between existing industrial development and proposed residential development. 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. Portions of the proposed urban extension area are within a 100 -year floodplain. Unless the development can qualify for a Flood Hazard Development Permit, most types of development within this floodplain should be discouraged. It should be encouraged that due to floodplain development restrictions, the majority of those areas within a 100 -year floodplain should be utilized as "open space" or "open space /wildlife." Deposits of sand and gravel exist within a portion of this floodplain. A portion of the proposed urban extension area has already been permitted for the extraction of these natural resources. Due to bonding limitations and expense, reclamation plans have been filed only on those acres currently being mined. VALCO, Inc. (discussed in greater detail in Section VIII -- Current Zoning and Land Use), is the major company currently excavating natural resources in the floodplains adjacent to the Arkansas River in the Southwest Quadrant. Their reclamation plan, the "Chain of Lakes" concept, is a reuse concept for the mined land whereby medium -size (20 -25 acres) lakes will be left along the Arkansas River for wildlife habitat (See Map VII). Water augmentation laws may have an impact on extraction plans which could result in exposed groundwater, such as these lakes, and may have an impact on current and future reclamation plans of those areas that contain a high groundwater table. Legislation is currently pending regarding the If date for which these type of evaporative losses would not need to be augmented. It should be encouraged that these extraction sites, particularly those along the Arkansas River, be reclaimed for "open space /wildlife" use. Reclamation of this property as such, coupled with the utilization of the 100 -year floodplain around the Goodnight Arroyo as "open space," will enhance and further the trails system within the Southwest Quadrant. Located southwest of the Regency Park Subdivision, also within the proposed urban extension area, is the old Southwest Dump. Records show that this dump has been inactive since approximately 1966. Little is known about the environmental constraints that may surface upon development of this property. Extensive testing should be required in order to ensure that safe and appropriate land use is established. This dump is described in more detail in Section VIII -- Current Zoning and Land Use. - 30 - ff la•' 4!2), north — 31 — C. DEVELOPMENT GUIDELINES All development within the Southwest Quadrant shall be undertaken in accordance with the then existing City Code of Ordinances 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. Rural— residential development (one to five acres) should be encouraged as the preferred residential use adjacent to the environmentally sensitive slopes south of the Arkansas River. b. Rural— residential development shall be permitted on slopes of 20 percent or greater if submitted with appropriate geology and soils tests that support little or no on —site or off —site hazards which will result due to this development. c. Transitional high— density residential (R -4, R -5, R -6) or office (0 -1) development should occur between single — family residential (R -1, R -2) and commercial (B -1, B -2, B -3) land uses. d. No single — family residential units (R -1, R -2, R -3, R -4) shall be permitted private access onto major transportation corridors. e. 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). f. 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. 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 VI 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. — 32 — 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. Industrial development mixed with highway commercial uses shall be permitted adjacent to I -25. 4. Mineral Resource Extraction Areas a. All mineral resource extraction areas that are 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. D. 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 service area. No point should be further than oni station. Additional fire stations or staff and equipment will be required to provide protection to area at build -out. The exact locations of new investigated, as these locations will be dependent place, new road construction, number and density factors which may affect response time. 3. Schools stations be central to their and one -half miles from the the purchase of additional the proposed urban extension fire stations have not been upon where development takes of new buildings, and other The proposed urban extension area is entirely within School District No. 60 boundaries. Decisions to build new school facilities are made on a case -by -case basis. The School District currently possesses future school sites in the Regency Park and E1 Camino Subdivisions. - 33 - E. PARKS, OPEN SPACE, AND TRAILS 1. Parks If the Southwest Quadrant experiences the majority of the residential growth as anticipated, it will become necessary to develop new parks in these growing areas to meet these 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' Rules and Regulations, October 18, 1983. a. Neiqhborhood Park A neighborhood park shall be developed on a minimum of five acres of land that is accessible to all subdivision residents. A neighborhood park shall provide sufficient areas for recreational activities including but not limited to playgrounds, multipurpose courts, and open and shaded grassed areas. When possible, dedicated parkland shall be located adjacent to school district facilities for shared usage. Dedication of drainage ways, steep slopes, or other "nondevelopable land" for use as parks is not 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 planned for the northeast corner of the proposed intersection of Lehigh Avenue and Bandera Boulevard (See Map VI). This park should be a minimum of 25 acres. It should provide specialized facilities such as court sports, a recreation center, and regulation —size playing fields. Large grass and tree areas and specially landscaped open areas, especially around the Goodnight Arroyo and its surrounding floodplain area, should be provided. 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 Arkansas River floodplain is considered to be a critical riparian habitat by the Colorado Division of Wildlife. Every attempt should be made to maintain this designated 100 —year floodplain in its natural state. Every effort should be made to reclaim and enhance those areas of the floodplain where previously disturbed and /or developed. These open spaces may be traversed by developed bicycle and pedestrian trails and scenic, historic, or archaeological viewing areas. — 34 — In such ca development demonstrate during the floodplain effect. se where development on a floodpl permit shall be obtained. that the encroachment shall not occurrence of the base flood shall be in accordance with ain is to be considered, a flood hazard A flood hazard development permit must result in any increase in flood levels discharge.

These bluffs typify the "southwest" topography and offer a visual quality to visitors and local residents traveling to the popular Pueblo Reservoir and State Park. It is recommended that the bluffs and adjacent lands, with slopes greater than 20 percent, be preserved as open space. 3. Trails To ensure continuity of the bicycle and pedestrian trails system, all developers should be responsible for the dedication of rights -of -way and the extension of these trail corridors through their developments. Alternately, the developers 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, the airport, and at central commercial centers. All trails shall be constructed pursuant to standards set forth by the Bicycle Systems and Trails Plan, then in effect. Map VIII illustrates potential trail locations. These lie primarily parallel to major roadways. A trail has been proposed to follow the Arkansas Valley Conduit. This conduit winds in a southeast direction from the Reservoir through the southwestern tip of the City to the St. Charles Reservoir No. 3. A trail along this conduit appears ideal. However, there are some concerns as to drainage and current motorized uses in the area. Trails along proposed parkways tying in recreational amenities such as the Arkansas River, the State Recreation Park, future neighborhood parks, Salt Creek, Goodnight Arroyo, and scenic vistas on the steep slopes south of the Arkansas River are all possible locations. - 35 - / -- = - =' } north a Pit Gad ,-�. ~ R is � • �' `� _ � Sht o-: .�\ ! ✓K ' �� ? ,�� � U s `.z \�' b\` o __ 1 i -: -� � � •ntc� ipa1���1�� .Ll�t�y5. � \.s;�� - _ AA Course r" pp yy'' o f �S i <e �tt3nsa s an C f�'d7 �� h4F� _('� s k y 0 I I• -_r" f � � i °' -� • c � .' � ``• "y •'r��a•,� -. ��� �4�� �t'.�trl F a., � ° 1 1 f �:.•. • <es � �� Y tf ���cfyc��'" r E a 1 t F -�1�1 �t ''9 ?s �lar .tart temr nt 4a cza. -El-(t 1:' 1 ' G ♦ LEMMiN AYE '�yi P_t -•'* Vic. c �t t �i y i V� ` 9�, ti , ♦ \ � i> r - �... •r f,.t <p�����!'�F�' PE a .._�• - - ' T ` � I I F • ' "'` �,�LY b� �3� � 3 � p� � i � x' €,1. ! t L '� !�i t f L O **lo .63 Chna•� Rre u 1 Q F •a ..

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 Southwest 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 are also 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 Southwest 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. Some of the most familiar natural resources that are found in the Southwest Quadrant include sand, gravel, and clay. 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 Southwest Quadrant consists of Carlile Shale, Greenhorn Limestone, Graneros Shale, Dakota Sandstone, and Niobrara formations (Kn) (See Map IX). Members of the Carlile Shales include Fairport Chalky Shale, Blue Hill Shale, Codell Sandstone Shale, and Juana Lopez. Greenhorn Limestone includes Bridge Creek Limestone, Hartland Shale, and Lincoln Limestone members. Members of the Niobrara (Kn) formations include Fort Hays Limestone and the overlying Smoky Hills Shale member. Fort Hays Limestone consists of approximately 82 percent limestone and 18 percent shale and does not pose any severe limitations to development. The Smoky Hill shale member consists of Upper Chalk Unit, Upper Chalky Shale Unit, Middle Shale Unit, Lower Limestone Unit, Lower Shale Unit, and the Shale and Limestone Unit. The Smoky Hill Shale member collectively is 700 ft. thick. Corresponding geologic properties can be found in Table II. Limited beds of Bentonite can be found in both the Carlile and Smoky Hill Shale formations. Bentonite has a high clay content which expands when the water level is increased. This expansion can cause damage to structures. Engineering techniques should be researched and utilized in areas that have been determined to have expansive soils. In addition, erosion of the Carlile Shale and difficulty of excavation of the Smoky Hill Shale member pose the primary engineering concerns in the area. — 37 — TABLE II: GEOLOGIC FOWATIONS— BEDROCK - 39 - USE AS BASE TYPI- MATERIAL CAL ENGI- DIRECTLY SYM- THICK- NEERING FOUNDATION SHRINK/ EXCAVATION UNDER FORMATION MEMBER BOL NESS PROBLEMS STABILITY SWELL ABILITY ROAD C(TT9EPJTS Fairport Carlile Chalky Fair to Easy to Shale --------------------------------------------------------- Shale Kc 99' Minor Poor Some 10 Ft.

Surficial Geology Some of the bedrock in the Southwest Quadrant is covered by surficial deposits (See Map X). This material is composed of clay, silt, sand and gravel, and other substances which have been deposited by wind and running water. These surficial deposits overlie the sedimentary bedrock except where faulting, folding, or erosion have exposed bedrock sections. Surficial deposits in the Southwest Quadrant include Broadway Alluvium (Qb), Colluvium (Qc), Eolian Sand (Qes), Piney -Creek Alluvium (Qp), Post -Piney Creek Alluvium (Qpp), and Slocum Alluvium (Qsa). The geologic properties of these deposits are located in Table III. The USGS has detailed maps locating surficial deposits in the Southwest Quadrant. It is recommended that these maps be used as reference during all stages of planning and development. a. Soils A soil association refers to a landscape that has a distinctive pattern of soils composition in defined proportions. Map XI illustrates soil associations in the Southwest 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 X, the soils in the Southwest Quadrant and their characteristics are: (1) River Bottom and Terrace Soils #6: Rocky Ford, Numb, and Korman Association - -Warm, deep well- drained, nearly level soils on terraces. #7: Las Association - -Warm, deep, poorly and somewhat poorly drained, nearly level soils on floodplains. (2) Plain Soils #8: Manvel, Minnequa, Penrose Association - -Warm, deep, and shallow, well drained, gently sloping soils on uplands plains. #21: Vona, Olney, and Dwyer Association - -Warm, deep, well- drained, gently sloping to moderately steep soils on uplands plains. (3) Foothills Soils #39: Cascajo and Sunsil Association - -Warm, deep, and shallow, excessively drained to well- drained, gently sloping to moderately steep soils on uplands breaks. #46: Penrose Association - -Warm, shallow, well- drained, steep and moderately steep soils on uplands breaks. - 41 - - 42 - TABLE III: GEOLOGIC PROPERTIES — SURFICIAL DEPOSITS USE AS BASE MATERIAL TYPICAL EXCA- DIRECTLY SURFICIAL SYM- THICK- FOUNDATION SHRINK/ VATION UNDER DEPOSIT BOL NESS ENGINEERING PROBLEMS STABILITY SWELL ABILITY ROAD OWNTS Broadway Little Good Alluviun Qb 12' -25' None Fair -good to none Easy Suitable penneability. -------------------------------------------------- - - - - -- High High sulfate; Not anticipated expan- erodes easily; because so sive Not thin; poor Colluviun Qc 10' thin layer.

Landforms Landforms are referred to as the topographical characteristics in a specific area. They are a result from the interaction of three factors -- structure, process, and stage. Structure is referred to as an existing surface or geologic structure which is 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 4,705 ft. above sea level at the Arkansas River to 5,344 ft. above sea level at San Carlos Mesa. The bluffs directly south of the Arkansas River floodplain are characterized by steep slopes with grades of ten percent or more. The physical characteristics of the Southwest Quadrant are illustrated on Map XII; they include a mesa, a terrace mesa, the floodplain of the Arkansas River, and plains. 4. Drainage The drainage basins in the Southwest Quadrant study area are the Boggs Creek Basin, Salt Creek Basin, and Blue Ribbon Creek Basin (See Map XIII). These basins are south bank tributaries to the Arkansas River, the region's primary watercourse. To obtain the greatest benefit from gravitational flow, the ultimate location of sanitary and storm sewers will be dictated by these drainage basins. a. Floodplains Four watercourses - -the Arkansas River, St. Charles Reservoirs, Salt Creek, and the Goodnight Arroyo - -are classified as 100 -year floodplains in this study area (See Map XIII). A 100 -year floodplain is considered as an area with a one - percent chance of flooding in any single year, or once every 100 years. Environmental constraints that result from these floodplain hazards are described in the accompanying Section B. The Arkansas River is the major river in Pueblo County. The Pueblo Conservancy District constructed flood levees along the Arkansas River after the flood of 1921. The Bureau of Reclamation's Pueblo Dam and Reservoir (Fryingpan- Arkansas Project) was completed in 1975. The U. S. Army Corps of Engineers has channelized and constructed flood levees on the Fountain Creek north of the Arkansas River/ Fountain Creek confluence. The levee project was completed in 1989. The levee systems and dam provide standard project flood protection to the Pueblo area west and immediately east of the Fountain Creek confluence. The Goodnight Arroyo originates approximately 1.4 miles south of State Highway 78, meanders north, then passes just west of West Park under the Bessemer Ditch and Highway 96 to the Arkansas River. It drains an area of 5.9 sq. miles. In this arroyo, flows result from snowmelt and rainfall during the winter and early spring and from thunder showers in the summer. The steep slopes and long, narrow shape of the drainage are conducive to fast rises and high peak flows of short duration. - 45 - fA � ��J %y. �_ x>C. 1 J h ,1 11 P `, t - ' !�', �•_ 0 C '� ' I � � �•, �t ' � ` i F V- north �sl i 36 � -• nh '/ �> � . � ,� C ibht � •• .xo6l � ,{ c.l p`" l g p t o Y d p`` 1_.p sat "`� 1 •'..

City of Pueblo Department of Planning & Development MAP: SOUTHWEST QUADRANT ANNEXATION MASTER PLAN XIII 47 - Salt Creek joins the Arkansas River in the southeast corner of the City of Pueblo. Salt Creek drains an area of 37.2 sq. miles. The Creek originates in the foothills and empties into the St. Charles Reservoirs Nos. 2 and 3; flows under I -25; travels six — and — one —half miles through the CF &I property; and then joins the Arkansas River. Except for the urban industrial encroachment existing in Salt Creek near its mouth on the Arkansas River, development has been minimal in the floodplain. b. Reservoirs There are two large bodies of water in the study area and one on the perimeter. St. Charles Reservoirs (dos. 2 and 3 are located on land owned by CF &I. These reservoirs provide water for the factory's production process. Administered through a private club, the area offers such recreation as fishing, hunting, and bird watching. The Pueblo Reservoir is located northwest of the study area and is incorporated into a large State park. This area provides many acres of habitat and offers fishing, hunting, boating, camping, and other recreational opportunities. c. Wetlands Wetlands are referred to as those areas that are inundated by surface water or groundwater. Wetlands generally include swamps, marshes, bogs, and similar areas such as sloughs, potholes, wet meadows, sewer overflows, mud flats, and natural ponds. A 0.5 sq. mile residential and light industrial area, located immediately south of Lake Minnequa, is underlain by an alluvial aquifer. This area is waterlogged, as the water table is less than six ft. below the land surface. The principal cause of the shallow water table is the high water level of Lake Minnequa. Seepage from St. Charles Reservoirs Nos. 1, 2, and 3 and from the bedrock hill east of the Lake and the northeast direction of groundwater flow also contribute to the problem. The most severely affected area is just south of Lake Minnequa. Map XIU locates regions where the water table is: (1) less than six ft.; (2) less than 10 ft.; (3) less than 20 ft.; and (4) less than 30 ft. below land surface. These areas lie primarily south of Lake Minnequa with extensions in the north reaching into the West Park area. In response to the alternatives suggested by the investigative report, 14aterloqqina in an Alluvial A uifer near Lake Minnequa, the City implemented an "Acquisition Relocation" Prograri for the residents in the waterlogged area "less than six ft. to the water table." The program utilized Community Development Block Grant Funds. To date all but one residence has been acquired and the occupants have been relocated. r j MAP KEY p 11 _� - g �, 1 {� J •rcx Waterlogged Area -Water Table Less � �-1 Than 6 Feet From Land Surface north :r� N TEN FEET Groundwater Depths From Land Surface 3fi — z vi' " " \!�` B .rvs ,_ ''�:i,� aln9 `` �{(tf[ "x � .ate �r /• "�(� :I: ,.,� l IE Crml :• �� G ( Ibhl � � �l ' '• it � N gll�4e e � �.Jf nCowse +� Y q A� 1 q 1 N �'.,.." r •��� ��'��e I � n11A1AgMilq, gl�g1lp !i. 4 ARx ��,g11 � -.

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 ". Temperatures in the summer reach 90 degrees or higher approximately one out of every two days. Afternoon thunderstorms account for much of the summer precipita— tion, with the probability of measurable precipitation being one day out of four. 6. Flora and Fauna Plant and animal associations are groups of species co— existing in a complementary manner. 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 Southwest 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 associations in the Southwest Quadrant include: a. Grasslands of the Plains - -Blue grama is the dominant grass with smaller traces of Western wheatgrass and Galleta present. b. Woodlands of the River Bottoms -- Varying amounts of Cottonwoods, Willows, Rabbitbrush, Forbes, Sages, Cattails, Wild rye, Alkali sacaton, Inland salt grass, Muhly, and Sand dropseed. 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 another species. Preservation and protection of habitat and species is imperative in maintaining the integrity of a native plant and of animal populations. c. Woodlands of the Foothills and Plains -- Vegetation includes Pinon pine, One seed and Rocky Mountain junipers, Mountain mahogany, Skunkbrush, Sumac, Gambel oak, Indian rice grass, Big and Little blue stem, Blue grama, Sideoats grama, and Western wheatgrass. - 50 - 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 Southwest Quadrant are Riparian, Urban, Woodland, and Plains Breaks and Grasslands. Habitats are valued in terms of food sources, vegetative cover, water availability, shelter, and breeding grounds. Different animal species relate to different habitats. According to the Colorado Division of Wildlife, the Arkansas River floodplain is considered to be critical Riparian habitat. Critical habitat is that which offers rare or limited environmental conditions and includes those areas which support rare and endangered plant or animal species. Animal inhabitants of the area include coyotes, antelope, small mammals, small birds, quail, larger raptors, crows, and a variety of waterfowl. The Arkansas River is included in the wintering ground of endangered species such as the American Bald Eagle, the Golden Eagle, and the Night Heron. It is imperative that the river environment is preserved and that endangered species are protected from further urban enchroachment. Zoning for parks and recreational open space is encouraged in the floodplain to help facilitate this preservation. 7. Water Quality The Southwest Quadrant consists of three drainage subbasins (See Map XIII). The subbasins are tributary to the Arkansas River Basin. Water quality standards and classifications have been adopted by and for the waters of the State to ensure the quality and acceptability of Colorado's waters for beneficial use. The mainstem segment the Middle Arkansas is located between above the confluenc Class I Recreation Domestic Water Supply of the Arkansas River within the study area is referred to as River, Segment 2, by the Section 208 Water Quality Plan. It the outlet of the Pueblo Reservoir and a point immediately with the Wildhorse /Dry Creek Arroyo and is classified as a and Cold Water Aquatic Life, and a Class II Agriculture and stream segment. This mainstem is immediately east of the Pueblo Reservoir. Due to the settling of suspended particles in the slower moving waters of the reservoir, water leaves the Dam outlet cooler and clearer than it entered. The 1977 Section 208 Stream Segment Analysis describes this segment of the Arkansas River as a swift flowing, near pristine river which is rich in dissolved oxygen and low in temperature and toxic chemicals. The parameters and results in which this stream segment was analyzed include: PARAMETER RESULT Dissolved Oxygen Consistently High Un- ionized Ammonia Within Safe Limits Fecal Coliform Within Safe Limits Suspended Solids Exceeds recommended limits for Cold Water Aquatic Life - 51 - These conditions support the use of this segment as a Primary Contact Recreation- - Aquatic Life -- Surface plater Supply area. The 1987 Section 208 Plan Update Nonpoint Source Pollution Assessment considers this segment to have "low- priority" impact. This is to say that "water quality data indicate no significant adverse impact on this stream segment by nonpoint source pollution." The Plan Update did not provide specific data. The 1977 Section 208 Stream Segment Analysis, however, states that the stormwater drainage systems and individual sewage disposal system leakages in the Goodnight (West Park) area result in the degradation of water quality. Groundwater in the entire Southwest Quadrant planning area is of poor quality, with concentrations of dissolved solids ranging from average to high. The groundwater is very hard. Calcium and sulfate are the predominant dissolved chemical constituents. Testing of domestic wells in the West Park area has shown high levels of compounds which can be a health hazard. Groundwater quality is further discussed in the "Water Service" Section of this plan. 8. Air Quality Air quality in the Southwest Quadrant poses no problem to human health and welfare. The entire Pueblo region complies with all National Ambient Air Quality Standards pursuant to the 1963 Clean Air Act, 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 local 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. Eventually, all monitoring will be done by PM -10 as this system allows for a more detailed analysis. The 1988 PM -10 results indicate that the Pueblo region has a 14 percent chance of noncompliance with Federal Ambient Air Quality Standards. This is considered a low priority 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 are no PM -10 monitoring stations located in this study area. The closest stations are at the Pueblo Memorial Airport and AIP and one atop the 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. - 52 - Q. 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, and large arroyos exist 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 INGRID Analysis (Improved Grid). This program was developed by the Department of Architecture of Harvard University's School of Design. This composite of Environmental Hazards is identified on Map XV. The potential hazards analyzed for Pueblo County and included in this report are: (1) Floodplain Hazards; (2) Wildfire Hazards; (3) Geologic Hazards: (a) unstable slopes; (b) mud flow /debris fans; (c) ground subsidence; (d) expansive soils and rocks; (e) seismic effects; (f) erosion; (g) Radioactivity; and (4) Mineral Resource Areas. The following text describes potential hazards in the Southwest Quadrant: Floodolain Hazards A floodplain is that flat 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[7]) 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 the area is thus 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. In this study area, the Arkansas River, the St. Charles Reservoirs, Salt Creek, and the Goodnight Arroyo are classified as 100 —year floodplains (See Map XIII). The Federal Insurance Administration has delineated areas of special flood hazards applicable to the City of Pueblo. These are shown on the Environmental Composite Map XV. Fine silt, raud, 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. It is the goal of zoning and development procedures to protect floodplains in order to freely discharge a base flood without increasing the water surface elevation more than 1 ft. 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. — 53 — 2, Wildfire Hazards Wildfires are any fires that are burning out of control including brush fires, forest fires, grass fires, and structure fires. A number of factors must work together 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. The Southwest Quadrant is classified as a Type "A" low wildfire hazard zone. Zones such as these contain sparse fuel sources (grasses, scrubs, trees, etc.). No measures which are over and above standard fire prevention development policies need to be implemented. 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; mud flows /debris fans; ground subsidence; expansive soils and rocks; seismic effects; erosion; and radioactivity (no hazards defined by IMGRID). a. Unstable Slopes Unstable slopes are areas where gravity can cause loose dirt, gravel, or any surface material 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 natural unstable slopes on channel banks. The slopes in the Southwest Quadrant are considered to be potentially unstable and have been identified on Map XV. These slopes can be 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. Mud Flows /Debris Fans Mud flows (also called earth flows or debris flows) are rapid movements of masses of earthen mud. Mud flows occur chiefly in dry canyons or arroyos in the semiarid regions 'and result from cloudbursts or snowmelt. Debris fans are deposits of gravel, mud, silt, small rocks, and other substances shaped like a triangle and are formed where a watercourse enters a larger valley. Debris fans are closely related to mud flows and are sometimes associated with each other. Building on or in the path of mud flows or on debris fans is extremely hazardous. Mud flows can be unpredictable and seemingly minor factors can trigger the flows. Moderate mud flows and debris fan hazards are found chiefly in the proximity of a floodplain. The "I[ 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 possessing only one of these components are located within the study area. They are indicated on Map XV. No IMGRID study cells contain more than one of these components. Developers should consider placement, design, and engineering practices prior to construction in the path of drainage ways or near arroyos. — 54 — c. Ground Subsidence Ground subsidence is referred to as a downward displacement of surface material. Ground subsidence can occur naturally or by man —made processes, such as: (1) the removal of groundwater; (2) the addition of water to weak soils; (3) the dissolving of certain rock formations by exposure to groundwater flows; and (4) the removal of materials by underground mining activities. The Southwest Quadrant does not have a severe subsidence problem. Map XV indicates that subsidence occurs primarily in the north and in several other scattered IMGRID cells. Techniques for mitigating problems caused by subsidence on structures do exist and should be reviewed prior to structural design. d. Expansive Soils and Rocks Expansive soils and rocks contain clay which due to their molecular structure expand to a significant degree upon wetting and shrink upon drying. Map V illustrates those areas found to have moderate to high expansive properties. Swelling soils are common in the study area. Much of the study area's soils range from low to high in their expansive properties. Several areas have been identified as having very high expansive properties (See Map XV). e. Seismic Effects Seismic effects are referred to the underground nuclear detonation impact the an area can increase the possibility of a rockfalls, unstable slopes, and flood po elements were compiled into the number cell. Three hazards were identified Quadrant, a few scattered cells exist These hazardous areas should be noted constraint to development. degree upon which earthquakes or an environment. An earthquake or tremor in geologic hazard occurrence. Landslides, tential would be greatly affected. These of potential seismic hazards present per by the IMGRID Program. In the Southwest which contain only one seismic hazard. but should not be considered a severe f. Erosion Erosion is the end — result of a culmination of factors such as vegetative and man —made cover types, gradient, the chemistry make —up of soil, weathering, overgrazing, and other man— caused disturbances. The erosion problem in the study area ranges from non — existing to severe or losing anywhere from 0 to 200 tons of soil per acre per year. The most detrimental soil losses occur in the sloping areas of San Carlos Mesa and the steep slopes just south of the Arkansas River. These areas may significantly contribute to stream sedimentation when disturbed. — 55 — 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 steep slopes along U.S. Highway 96 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. Sensitive erosion areas are located on Map XV. The City of Pueblo is in the process of preparing a Storm Drainage Criteria Manual which will include the criteria for a required erosion control plan during development. g. 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 Southwest 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. 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 Survey. Deposits of sand and gravel are abundant near the Arkansas River. Prior to extraction of a natural resource, 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. - 57 - permits for extraction and processing of sand and gravel and exploration of natural resources are issued by the County Planning Commission. Active and inactive extraction pits, processing operations, and exploration sites within the Southwest Quadrant are located on Map XVI, and the corresponding status and types are listed below: Special Use Permit Status Type No. 40 Terminated -- 7/27/69 Extraction /Processing No. 145 Withdrawn -- 10/7/70 Extraction /Processing No. 428 Active " /" No. 479 Active /" No. 550 Active Oil /Gas Exploration 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 likewise will result in the extension of municipal services. This section will describe the existing transportation routes, water and waste— water systems, electrical 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 Southwest Quadrant are: 1. Interstate 25, a freeway which serves as the primary north /south roadway in Pueblo and along the Front Range; 2. Pueblo Boulevard which serves as a loop "expressway" and principal arterial connecting U. S. Highway 50 —C and Interstate 25 South; 3. Colorado State Highway 78, an east /west highway leaves the City as an expressway and continues to Beulah as a principal arterial; 4. Colorado State Highway 96 traverses the City in an east /west direction as Fourth Street, Lincoln Street, and Thatcher Avenue. It is a principal arterial. 5. Within the City limits, Prairie Avenue (running north /south) and Northern Avenue (running east /west) are both principal arterials; and 6. Hollywood Drive, Jones Avenue, and St. Clair Avenue are minor arterials; Red Creek Springs Road is a "collector" arterial. Residents of the Southwest Quadrant and public officials have expressed concern over several primary access roads. They are: a. Encino Drive, classified as a collector which actually functions as a minor arterial, serves as the only ingress /egress into the E1 Camino Subdivision. This single access point has been a concern to subdivision residents and emergency service operators. In addition, there are existing plans to expand the subdivision to the south (El Camino Parks Subdivision), thereby further impacting the roadway. — 61 — b. Bridle Trail, currently classified as a collector, wil Arkansas Valley Conduit and serve the El Camino Subdivisions. No specific date for the extension has developer. Although this extension will provide a much into El Camino, it will only minimally reduce traffic the layout of the subdivision. eventually bridge the and El Camino Parks been identified by the needed second entrance on Encino Drive due to C. McCarthy Boulevard, a County road classified as a collector, serves as the only ingress /egress into the Stonemoor Hills Subdivision. Additional development is being proposed in the area which will also utilize McCarthy Boulevard for its ingress /egress. County officials have planned a southern extension of McCarthy Boulevard to Red Creek Springs Road, thereby providing a second entrance into the area. These concerns have been addressed in Section IV, the Southwest Quadrant Three- 1.1ile Annexation Plan, of this report. 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 its successor the Year 2010 Transportation Plan The Year 2010 Transportation Plan utilized computer modeling (TRANPLAN) and actual vehicle counts to determine the degree of efficiency of the current transportation network. Any deficiencies were then analyzed and the effects of alternate roadways were examined. 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 Southwest Quadrant is comprised of nine zones. Table IV lists the Evaluation's projections; Map XVII illustrates corresponding traffic zones. Those traffic zones within City limits are expected to grow at moderate rates. The highest predicted rates of growth will be in the newer residential areas of Regency Park and El Camino (Zones 115 and 117). Employment is expected to increase along Pueblo Boulevard in Zone 119. Zone 116 is predicted to remain primarily undeveloped until those areas east of it achieve build —out. Results from the TRANPLAN evaluation indicate that the unincorporated area of the Southwest Quadrant will not require intensive transportation improvements by the Year 2010. In order that future subdivision proposals provide adequate rights —of —way and future roadways align into a planned framework, the Southwest Quadrant Three —Mile Annexation Plan, Section IV of this report, proposes future roadway corridors. These corridors are proposed now, regardless of immediate need, so that the City's transportation system remains cohesive. — 62 — TABLE IV: ANALYSIS DISTRICT EVALUATION TO THE YEAR 2010 DISTRICT NO. 1980 1990 2000 2010 No. 113 Population 1,124 982 1,230 1,303 Dwelling Units 409 377 491 530 Employment 75 150 173 196 No. 114 Population 1,737 2,325 2,907 3,082 Dwelling Units 612 981 1,276 1,379 Employment 47 197 227 257 No. 115 Population 972 1,493 1,869 1,981 Dwelling Units 393 630 820 886 Employment 24 274 317 360 No. 116 Population 154 251 314 643 Dwelling Units 66 106 138 288 Employment 0 0 0 0 No. 117 Population 5,232 6,157 7,166 7,748 Dwelling Units 1,580 2,084 2,516 2,772 Employment 275 375 470 520 No. 118 Population 1,791 1,698 1,638 1,607 Dwelling Units 513 513 513 513 Employment 30 130 160 235 No. 119 Population 0 0 0 0 Dwelling Units 0 0 0 0 Employment 21 321 446 571 No. 120 Population 1 2,615 3,042 3,287 Dwelling Units 671 885 1,068 1,176 Employment 0 0 0 0 No. 121 Population 127 145 168 182 Dwelling Units 37 49 59 65 Employment 0 0 0 0 Zone 113 contains West Park and areas north of the River. —63— �f� �` "" ffffflfft, h � "nun � B. 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. Several suppliers provide water to the Southwest Quadrant study area. They include the Pueblo Gardens and Sunset View Water Associations (which are at their service capacity) which serve a few households in the West Park area and the Pueblo Board of Water Works. The Pueblo Board of Water Works is the primary purveyor of water for the City of Pueblo. The Board does not have a franchise agreement with the City; therefore, upon annexation, private water suppliers may continue service to their customers. 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. A "peaking plant" could be constructed on this site when expansion is necessary. 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 McCabe and LaVista pumping stations serve South and Southwest Pueblo. Storage tanks are located at Hellbeck, LaVista, and Westmoor. The Hellbeck and LaVista storage tanks serve the Southwest portion of the City in the 2000 Zone. The tanks at Westmoor serve the 6000 Zone and by utilizing pressure reducing valves are able to serve the 4000 Zone. The pressure zones are defined by elevation as follows: Zone 2000 -- serves elevations 4750 -4850; Zone 4000 -- serves elevations 4850 -4950; Zone 6000 -- serves elevations 4950 -5050; Zone 8000 -- serves elevations 5050 -5200 (See Hap XVIII). In order to service those areas in the 8000 Zone, including a part of the proposed El Camino Parks Subdivision, major improvements will have to be made. A developer may be required to install, at his expense, a pumping station at the Westmoor storage tanks and an additional storage tank at approxiiiately the 5,300 ft. elevation level. Development in the 10000 Zone will necessitate installation of additional equipment. The Board of plater Works has no plans at this time to pursue such improvements. It is proposed that the La 1 Encantada Subdivision, atop the San Carlos Mesa, will be serviced by a private water main from the Westmoor - 65 - -• 66 - storage area. Each residence in this subdivision will be required by the developer to install individual storage tanks and pumps. The Board of Water Works serves all areas within City limits and extends extraterritorial water to Stonemoor Hills and a portion of blest Park. It is doubtful that all of West Park will request Board water as a result of large up —front costs of water main extensions in some areas. As long as individuals feel that their water is palatable, there is no incentive to seek a costly extension. 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 XIX). 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 being guaranteed the current levels. The service through new, and became effective obtained from the Board signed, the applicant has 120 days in which to act while established fees. After this time, fees will be adjusted to plant water investment fee is charged to customers seeking additional, or increased size of meter or number of units, January 1, 1989. The fees are updated regularly and may be of Mater Works. 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 that the workload of the Board does not allow for any scheduling of water main installation. There is a one —year completion deadline and no extension of time will be granted. Furthermore, the established costs per linear ft. do not refer to the applicant's actual cost to install the water main. In certain areas, such actual costs may exceed the outlined costs. Any additional costs are the responsibility of the applicant. There are areas within the Southwest Quadrant in which water from the Board of Water Works is not available. Additionally, some residents that could obtain Board of hater Works water choose not to. In both these instances residents normally utilize private wells. The groundwater within portions of the Southwest Quadrant is known to be of poor quality and is not considered a guaranteed safe water source without proper treatment. A specific neighborhood of concern is the blest Park area. Approximately one third of the blest Park area residents use well water. The private wells are typically shallow and the groundwater is of such quality as to constitute a potential health hazard due to contamination from septic systems and agricultural land uses (e.g., livestock, large gardens). — 67 — In 1974, 1976, and 1983, the Pueblo City— County Health Department and the Pueblo Regional Planning Commission conducted groundwater quality assessments. The studies indicated high levels of Total Dissolved Solids, Nitrate, Sulfate, and Total Coliform. An informational report, Groundwater Quality West Park Neighborhood, Pueblo Colorado May, 1987, was prepared by the County of Pueblo, Department of Planning and Development. The report was funded through the Pueblo Area Council of Governments Section 205(j) Program. The report was distributed in June and July, 1987, to the approximately 125 households in the West Park neighborhood who are using private individual wells as their source of potable water. The purpose of the report was to: — Inform residents and property owners of the quality of groundwater in the neighborhood; — Inform residents and property owners of potential health effects associated with drinking the groundwater; and — Inform the residents and property owners of drinking water alternatives which may be available to them. The Pueblo City— County Health Department provided an analysis of well water to the first 24 responding households at no cost. Seventeen analyses were provided in July, 1987, and two in August, 1987. The well water was analyzed for the Total Coliform, Total Solids, Nitrate, Sulfate, and Phosphorous. The results of those 19 analyses conducted in July and August, 1987, by the health department are reported in Table V in comparison to the testing done in 1974, 1976, and 1983. Seven of the 19 wells sampled showed concentrations of Nitrate exceeding the standard of 45 mg /l NO3, with the highest level being 103 mg /1. The quality of groundwater from many wells in the West Park neighborhood is extremely poor and potentially fatal to small infants. Nitrate is the pollutant of most immediate concern because of its potentially fatal impact on the fetus and infants under two years of age. Methemoglobin, sometimes called "blue baby disease," can can be caused by Nitrate levels which are significantly below the Environmental Protection Agency's (EPA's) standard of 45 mg /1. In fact, local health officials recommend that water exceeding 4.5 mg /1, ten times less than the EPA standard, not be used as drinking water for infants, nor mixed with infants' powdered, concentrated food formula. Pregnant women and nursing mothers should avoid drinking water that exceeds the Nitrate standard. The quality of groundwater also appears to be deteriorating (See 1983 versus 1987 results). Water seepage from the Bessemer Irrigation Ditch and seepage and irrigation water from the West Pueblo Ditch may have a "flushing" action on the neighborhood's groundwater, causing improved quality when the ditches are running (April — October) and lower quality when they're dry. If this is true, then the quality of the groundwater is even lower during November through March than the July, 1987, analysis indicates. The County of Pueblo has been researching the possible extension of the Board of Water Works service to the remaining homes in blest Park. In review of the proposal, the Board has estimated the cost for main installation including asphalt and concrete replacement would be $391,566 (1988 Board estimates 93 homes do not have water service). The Boggs Creek Water District is proposing to provide water service to a possible 150 to 200 future home sites along State Highway 78 in the southwest corner of the study area. This "District" has an option to purchase water from the CF &I and would then transport the water from a CF &I ,creek to the service area. The formation of this water district is in the planning stage of development and has obtained the required 1041 Permit from the Board of County Commissioners but has not finalized the financing of the District. 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 through the provisions of Senate Bill 213 (1973) non — tributary status can be established. 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 wells are assured to produce potable water. Based on these conditions, it can be assumed that most of the future growth in the 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; the plant began full operation in 1989. Map XIX 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. 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. 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. — 70 — TABLE V: WEST PARK AREA -- AVERAGE QUALITY OF GROUNDWATER SAMPLED TOTAL PARAMETER TOTAL COLIFORM FECAL COLIFORM DISSOLVED SOLIDS DRINKING WATER STANDARDS' 4 Coliform /100 nil Coliform /100 ml 500 mg /l Year 1974 mg /l 12.8/100 inl (15) 1.0/100 nil (15) 1,868 Year 1976 mg /l 13.2/100 ml (36) 0.21100 ml (35) 1,357 (14) Year 1983 5.1/100 ml (15) NS 1,491 mg (15) Year 1987 8.8/100 ml (19)yY NS 1,830 mg (19) PARAMETER NITRATE AS NO3 SULFATE SELENIUM DRINKING MATER STANDARDS' 45 mg /l 250 mg /l 0.01 mq /1 Year 1974 123 mg /l (27) 680 mg /l (26) NS Year 1976 NR 252 mg /l (36) 0.005 mg /l (36) Year 1983 42 mg /l (15) 667 mg /l (25) NS Year 1987 41 mg /l (19) 695 mg /l (19) NS ( ) Indicates number of wells sampled. For example: (15) means 15 wells were sampled. NS Indicates Not Sampled. NR Means Not Reported. Nitrate was analyzed in 1976. The data is not reported herein because: (1) a nonstandard laboratory method was used which may have produced invalid and /or noncomparable data; and (2) it is questionable whether the results reported Nitrate as N or as NO3. - The quality of drinking water in individual household wells is NOT regulated by any quality standards. The decision to drink or not drink the water is left up to the residents of the house. The Colorado Board of Health's. drinking water standards do apply to "public water systems," such as the Board of Water Works of Pueblo and St. Charles Mesa Water District. These standards are presented in this report for information and comparison purposes. The drinking water "standards" referenced in this table are either the Board of Health's drinking water standards or the Environmental Protection Agency's recommended standards, except for Fecal Coliform which has no standard because it is included within Total Coliform. Sixteen wells were sampled in 1974 and in 1974 and one in 1987 (as of 8/19/87) too numerous to count (TNTC) and are not 17 (as of 8/19/87) in 1987. One well had Total Coliform readings that were included in the average. — 71 — 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 Southwest Quadrant served by extraterritorial City wastewater services. On -site sewage disposal systems are also utilized in the unincorporated area of the Southwest Quadrant. Such facilities include septic tanks and package sewer treatment plants, with septic tanks being far more common. Package plants are sold as a complete unit in a variety of types, some serving small communities and others a single household. Septic tank pumpers and haulers who pump out septic systems and dispose of 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 and complaints on safety and dumping can result in the revocation of a license. t4hen an area is annexed, the City of Pueblo assumes wastewater service. Impacts by development on the City sewerage and wastewater treatment system will depend on the amount and type of development. A treatment plant is designed to adequately process wastewater during peak hours (morning and early evening hours). Residential development has the most impact on the system, with high- density units being the most severe. Typically, commercial and industrial uses are not in full operation at peak hours. Prior to annexation to the City of Pueblo, a sanitary sewer report will be completed outlining the proposed development and its probable impact on the stormwater drainage and wastewater treatment system. (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. - 72 - 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 Southwest Quadrant is provided electrical power by WestPlains Energy Corporation (formerly Centel Corporation) and San Isabel Electric Association (See Map XX). The company has a franchise agreement with the City of Pueblo to be the sole provider of electricity within municipal boundaries. Upon annexation, any areas within San Isabel Electric's service area will be transferred to WestPlains' service area. WestPlains operates an electrical power generating station at 105 S. Victoria Avenue. Initially, the plant burned coal to generate electrical 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. Generating facilities at the plant consist of two units with a capacity of 8,000 kilowatts each; one unit with 19,000 kilowatts capacity; and five diesel generators, each with a capacity of 2,000 kilowatts. WestPlains 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 purchases approximately 65 percent of its power requirements from Public Service Company of Colorado under a renewable 20 year contract. WestPlains is a member of the Colorado Power Pool which includes Public Service Company, the City of Colorado Springs, and the City of Lamar. The power pool provides backup power in the event WestPlains 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 distributes electrical energy throughout the City of Pueblo through its transmission and distribution network. The Southwest Quadrant of the City is served by two distribution substations. These substations are served by 69,000 and 115,000 volt electric transmission lines (See Map XX). The transmission lines are located on utility easements of 120 ft. for parallel lines and 100 ft. for single lines. WestPlains officials state that all requests for electrical service in the study area can be fulfilled with reasonable promptness. WestPlains' 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 estii on — 73 — - 74 - the basis of the anticipated construction and installation costs, including materials, labor, rights -of -way, trenching, backfill, tree trimming, and any incidental and overhead expenses. An applicant for permanent service is required to pay all distribution extension costs in excess of a construction allowance determined by WestPlains. 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 rude. Indeterminate and temporary customers are required to pay all distribution extension costs and do not receive refunds unless reclassified as permanent by 1JestPlains. E. GAS The Public Service Company of Colorado provides gas service to the City of Pueblo and the surrounding area, including the West Park area and the Pueblo Darn. La Mesa Encantada Subdivision will also be serviced by the Public Service Company when development begins. 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. CIG pipelines are located east and south of the City. They lie in a 100 ft. easement. The main taps on CIG lines are located in Belmont in the Northeast and at Salt Creek near CF &I in the Southeast. The gas is then distributed by the company. 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, his or her share of the construction payment is refunded to those 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. - 75 - F. TELEPHONE U. S. West Communications provides local telephone service to the City of Pueblo and to the Southwest 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 installation payments. This occurs when new customers use the new distribution lines and when initial construction payments are recalculated to include the new customer. Service to the Southwest Quadrant would be relatively simple as distribution lines already serve a large portion of the area. U. S. West prefers to work closely with the developer so as to efficiently serve new customers. Such cooperation facilitates the acquisition of 20 —foot easements for the cables and poles; it also ensures the use of the most appropriate communications system. G. CABLE TELEVISION The Southwest Quadrant is in the service area of Telecommunications, Inc. (TCI), Cablevision of Colorado. TCI Cablevision offers cable television hookup and an array of programming packages. TCI Cablevision serves all areas in the Southwest Quadrant portion of the City of Pueblo and has extended its service to the West Park area. The company does not yet serve Stonemoor Hills Subdivision. The company requires that there be 28 to 35 residences per sq. mile prior to considering the extension of services. If service is to be offered, company technicians estimate the total cost of materials, labor, and installation methods needed to extend service. An application is made to the company's budget committee for approval. The application and installation process takes approximately one year. TCI Cablevision has a contract to use U. 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. — 76 — 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 impact 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 Southwest Quadrant. The impact 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, while School District 70 encompasses the remainder of the County. District boundaries are not precisely the same as City limits in that some "City" children go to "County" schools and vice versa (See Map XXI). The Southwest Quadrant study area is almost entirely within School District No. 60 boundaries. School District No. 60. School District No. 60 is divided into four high school service areas which relate closely to the City's North, East, 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 (Keating). 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 school sites currently exist in the Regency Park and El Camino Subdivisions. Within the Southwest Quadrant, School District No. 60 currently serves the area south of the Arkansas River and west of I -25 with eight elementary schools, three middle schools, two high schools, and a continuing education center. The middle schools and high schools have adequate room for enrollment growth; however, due to new residential developments, such as Regency Park and El Camino, many of the elementary schools are nearing capacity. Table VI illustrates 1991 -92 enrollments and school capacities for those schools in the Southwest Quadrant. — 77 — TABLE VI: SCHOOL DISTRICT NO. 60 ENROLLP]ENT 1991 -1992 SCHOOL ENROLLMENT CAPACITY Elementary Beulah Heights 410 455 Columbian 630 600 Goodnight 421 435 Hellbeck 424 430 Highland Park 617 620 Jefferson 358 450 South Park 324 400 Sunset Park 464 500 Mirlr]1a Roncalli 646 700 Pitts 830 900 High School South 1,459 1,800 SOURCE: School District 60, Office of Pupil Personnel, 1992. 2. School District No. 70 School District No. 70 maintains one high school, one middle school, two elementary schools, and Beulah School which functions as both an elementary and a middle school. Pueblo County High, Pleasant View Middle, and Beulah and South Miesa Elementary Schools serve a very small portion of the Southwest Quadrant. These schools have adequate room for enrollment growth (See Table VII). School District No. 70 is not experiencing intense pressure associated with rapid development and increasing enrollment. This may change with continuing growth and annexation by the metropolitan area. Presently, population is lightly concentrated along U. S. Highway 50 and sparsely distributed throughout the rest of the County. The schools in District No. 70 are considered "suburban" schools by the Colorado Department of Education. Approximately 94 percent of the students are bussed to schools. The District identifies philosophically with neighborhood schools and would construct additional facilities in an area to meet the demands of growth and development. -79- 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 ten to fifteen acres are needed for an elementary school, twenty to twenty —five for a middle school, and thirty —five to forty acres for a high school.

Detachment and Anne xation 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 are 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 County school 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 County 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. SI 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. When 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) serving a portion of the City, and smaller parks serving 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 shown in Table VIII below: TABLE VIII: 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 Park /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 /Median: A landscaped thoroughfare providing 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 8 ft.) 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. — 81 — 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 Pueblo 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 of 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 are earmarked for "allowable" parks and recreation projects. Funding is supplemented with State and Federal grants. Recreational facilities in the City portion of the study area occupy over 500 acres of open space and recreational land. Table IX lists these areas, their acreages, and classification. Map XXII identifies their location. It should be noted that the City Park and Zoo and the Municipal Golf Course are located in this quadrant and thus accounts for the high acreage allotment. The 1930 Urban Parks Recovery Action Program states that there is a lack of medium and large scale recreational facilities City —wide. However, the Southwest portion of the City enjoys the proximity to City Park and to the Pueblo Dam and Reservoir State Park. The Southwest Quadrant has the largest inventory of diversified facilities of all the planning districts. Of the total parkland in the Southwest Quadrant, approximately seven to ten percent (7 -10 %) of parks and recreational land is undeveloped or of low development status. Those areas noted are Hudspeth Park, "Regency Park" Park, Carlile School —Park, and Columbian, Jefferson, and Lincoln School playgrounds. Officials at the 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. —32— TABLE IX: URBAN RECREATION FACILITIES -- SOUTHWEST QUADRANT Approximate' FACILITY Acreage Recreational Land City Park 182.10 City Golf Course 192.12 Neiqhborhood Parks Beckwood 10.56 Briarwood 4.67 El Camino Parkland 23.70 Hudspeth 10.00 Lehigh 8.00 Pitts 17.00 Sangre de Cristo 3.00 Starlite 4.00 Sunset Park "Park" 2.54 Vinewood 5.45 School -Parks Goodnight 5.30 Sunset Park 5.76 Pitts 10.11 South High 12.00 Roncalli 13.67 Beulah Heights 5.58 TOTAL ACREAGE: 515.56 Acreage provided by Pueblo Parks and Recreation Department' Urban Parks and Recreation Recovery Action Program (1980). 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 are 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 trail's 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. - 83 - • � The Pueblo Bicycle System and Trails Plan was completed in 1990 by the City of Pueblo Department of Planning and Development. This plan thoroughly 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 pleasurable 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 multipurpose 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. 3. Recreational Areas Out City Limits a. The St. Charles Reservoirs N os. 2 and 3 The St. Charles Reservoirs Nos. 2 and 3 offer limited recreational uses. Most activities such as hunting and fishing are managed by a private sports club. The reservoirs are on land owned by CF &I and are available for recreational use to a paying membership. b. The Pueblo Darn and Reservo State Park The Pueblo Dam and Reservoir State Park is not within the study area; however, its location offers a wealth of recreational opportunities to Pueblo and to any future development in the Southwest Quadrant. This park is accessed off of State Highway 96, approximately six miles west of the City of Pueblo. Serving Southern Colorado, this State Park consists of 17,863 acres with 14,000 acres available for recreational purposes. The upper reaches of the park are reserved for wildlife preservation under the management of the Colorado State Division of Wildlife. The lower reaches function as a recreational area under the management of the Colorado State Division of Parks and Recreation. The activities offered include water sports, limited hunting, fishing, hiking, bicycling, and picnicking. A fee is charged to those persons entering the park by automobile or motorcycle. C. FIRE 1. City 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. -85- 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. The Southwest portion of the City is served by four fire stations. Map XXIII illustrates the respective protection zones. Station No. 3 , located at 123 14. Evans, is equipped with a medical rescue unit and a pumper truck. It is staffed by three, five — person shifts. Station No. 4 , located at 1201 E. Evans, is equipped with a three —way pumper truck. This station employs three, three — person shifts. The station also houses the Hazardous Materials (HAZ —MAT) Response Team. This crew is specially trained and equipped to contain hazardous material accidents. This team will respond to emergencies County —wide. Station No. 7 , located at Pueblo Boulevard and St C1 i ' A ar venue, is equipped with three —way pumper truck and is staffed by three, three — person shifts. Station No. 9 , located on Prairie Avenue and 2500 Aster, is equipped with a three —way pumper truck and staffed by three, three — person shifts. 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 is needed, the Fire Department will apply for special funding from City Council. A new fire station, utilities, a new pumper truck, equipment, and fire fighter salaries (3 shifts and backup personnel) would initially amount to approximately $861,000 (1988 dollars). Annual operation costs would be approximately $400,000 (1988 dollars). By 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 between four and one —half and five minutes to any point in the service area. Roadways, accessibility, and the number and density of housing units are all factors contributing to new fire station locations. 2. West Park Fire Protection District The West Park Protection District is operated from one station located at 3926 Goodnight Avenue. It is staffed entirely by volunteers and equipped with two pumper trucks, one 1,500 gallon tanker truck, and one pickup truck. The districts service area, which is entirely within the unincorporated area, is depicted on Map XXIII. Funding for the district is provided through a special tax district. As all or portions of the district's service area annexes into the City, the district's tax base will be reduced. Reduction of the tax base will require the district to increase its mill levy. This will continue until financing of the fire station becomes economically unfeasible. The West Park Fire Protection District has Pueblo Fire Department stating that either request, in the event of an emergency. medical assistance. a mutual aid agreement with the City of department will assist the other, upon The !Test Park District does not provide — 86 — - 87 - 3. Unincorporated Area With the exception of the West Park Fire Protection District's service area, the unincorporated area of the Southwest 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. D. POLICE City Police Department The Pueblo City Police Department is located at 130 Central Main Street. All operations are headquartered at this location. There are no substations. The department employs 171 authorized sworn officers and maintains an array of patrol vehicles. The City is divided into ten beats, or routes, which are patrolled 24 hours a day in three shifts. The annual cost for one beat is approximately $207,500, including three, one — person shifts of officers, backup personnel, and automobile expenses and repairs (1989 Dollars). 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 Police Department's study. The Southwest portion of the City is protected by five patrol routes. The area is not busy by official police terms. The Police Chief stated that there would be no need in the foreseeable future to establish another patrol route in the Southwest Quadrant. Annexation may trigger the expansion of current beats and the need for additional patrol officers within the current police framework. 2. County Sheriff Department The County Sheriff deputies patrol all areas outside the City, with the exception of the airport and airport industrial park. They frequently patrol the West Park and the Stonemoor Hills areas. 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 development trends. These continue to develop into document current zoning an, land uses recommended by planning policies. A. CITY ZONING this study area reflect historical as well as current trends indicate that the Southwest Quadrant will likely an extensive residential area. This section will J land uses in both the City and the County. Zoning and this plan reflect a desire for compatible yet flexible Zoning trends in the southwestern part of the City are primarily designated as single - family residential. Urban subdivisions include Sunset Park, Regency Park, E1 Camino, Highland Park, Starlite Hills, and Sunny Heights. The La Vista Hills Subdivision, located immediately east of the Arkansas Valley Conduit, is a rural subdivision zoned A -4 (Agricultural, minimum one -half acre). Commercial zones are found along Pueblo Boulevard and Prairie Avenue and in pockets along State Highways 78 and 96. Light industrial zones are scattered along Prairie Avenue, including Graneros Industrial Park on the southern border of the City. Several hundred acres of vacant, light- industrial land and some open rangeland lie adjacent to Interstate 25 South (See Map XXIV). B. COUNTY ZONING Areas in the unincorporated portion of the study area space rangeland. The blest Park and Stonemoor Hills areas west of Regency Park are zoned rural - residential. Regency Park are zoned for medium- density residentia parcels of public land and one commercial parcel are (See Map XXV). C. LAND USES 1. General are primarily zoned open and the area immediately Areas north and south of development. Two small located along Highway 78 Land uses in the Southwest Quadrant study area are primarily.urban and rural residential. These residential uses are supported by commercial uses along Pueblo Boulevard, Prairie Avenue, Northern Avenue, and Thatcher Avenue. The Graneros Industrial Park is located at the southern boundary of the City. The majority of land in the unincorporated portion of the Southwest Quadrant serves as open rangeland. Also within the study area are two active mineral extraction sites and an oil /gas exploration site. The Pueblo City- County Landfill known as the South Side Landfill and the closed Southwest Dump are discussed in detail under their own subsections. - 89 - City Boundary Study Area Boundary KEY t; 7 Ir a,, S-1 _ 2 L] pq [T-" E3 T - I 2 t E m� . $;j Single-family residential (R-1, R-2) Multi-family residential/Office (R-3 R-4, R-5, R-6) ...........

Farmland The economy of Pueblo County is partially based on the farming and ranching industry. The U. S. Department of Agriculture, Soil Conservation Service, is charged with the responsibility of identifying and locating prime and unique farmlands. This important farmland program also encourages the identification of farmlands of Statewide and local importance. The Soil Conservation Service has classified much of the open rangeland in the Southwest Quadrant as "prime land if irrigated," as shown on Map XXVI. Small farming operations are located along Salt Creek. However, the high cost of irrigation to most of the Southwest Quadrant is a deterrent to large —scale farming in the study area. 3. The Pueblo City— Countv Landfill This solid waste disposal site and facility, also known as the Pueblo South Side Landfill, is located southwest of the City of Pueblo and northwest of State Highway 78 (See Map XXVII). The City of Pueblo annexed the entire landfill site in May of 1990. Zupan has purchased 90 + acres for Phase II, III, and the Borrow area. This landfill was initially operated as a dump when open burning was routine and application of daily cover was not yet practiced. Conversion of the dump to a landfill began around 1968. Colorado's "Solid 1-4aste Disposal Sites and Facilities Regulations" were adopted February 16, 1972, and became effective April 1, 1972. The initial Certificate of Designation (COD) for the Pueblo Southside Landfill, as per State regulations, was issued by the Board of County Commissioners on September 19, 1972. The COD was subsequently amended on January 8, 1985, and again on December 13, 1988. The 1985 amendment increased the total area within the COD boundary to approximately 361 acres. The increased acreage provided additional area for landfilling, but most importantly provided an on —site area to obtain sufficient materials for daily intermediate and final cover of the waste (referred to as the Borrow Area on [1ap XXVII). The 1988 amendment was precipitated to allow an additional volume equal to 20 months of landfill life to be added to the landfill. The City was given approval by the State Health Department in February, 1991, to change the final contours of the landfill to allow continuing operation to approximately October of 1991. In April of 1991, the City entered into an agreement with Zupan Enterprises to sell approximately 90 acres of the property within the COD area for future landfilling. This included the Phase II and II areas which have been approved for landfilling by the State. The landfill accepts solid wastes (refuse and garbage) but is not permitted to store nor dispose of hazardous wastes on the premises. — 92 — k = lit =;M1 1111M a! ����Neq ■ ■RU =#1■ ■■11IMmfaq ,s �a�. 2 9, NP .do a4la;Rn "M11311 §§ I I He| ,WWI VaRARSHMr ■ � � �; 2' q « R 91a P � ^ ._�. �§ ��� \ ■� #! When the Pueblo South Side Landfill area is closed (Phase I), a lengthy reclamation period (between 10 to 50 years) may be required because of the very dry area in which the landfill is located in. By State law, post - closure monitoring of the landfill for subsidence, methane gas leakage, groundwater quality, and success of reclamation must be conducted for a period of five years. If problems arise with any of these monitored elements, the monitoring time may be extended.

The iiajority of the Valco property is located within the Southwest Quadrant's proposed urban extension area. In addition, Valco is currently in the process of negotiating a contract with the Colorado Division of Parks and Recreation for gravel extraction on 40 acres along the north bank of the Arkansas River which will also require a special use permit. Valco's reclamation plan applies only to lands currently within SUP #479 and does not include the proposed 40 -acre addition. Their reclamation plan for the permitted property is the "Chain of Lakes" concept. This plan is a reuse concept for the mined land whereby inedium size (20 -25 acres) lakes will be left along the Arkansas River. The additional 40 -acre mine site is anticipated to be reclaimed as a 30 -acre lake. - 95 - Mining has occurred only on the south side of the Arkansas River. Mining on the north side of the river will result in the relocation of the existing bike trail north to the bluffs. The City of Pueblo received a State trails grant for this purpose. Located within the Valco property, south of the Arkansas River, is the "Charles Goodnight Barn." The Goodnight Barn, which is on the National Register of Historic Places, is all that remains of the Goodnight Ranch. The ranch was established in Pueblo County in 1869 by Charles Goodnight. 11r. Goodnight is famous for cattle drives from his ranch in Texas north to Colorado along the Goodnight Trail. Goodnight was the first to set up an extensive cattle ranching industry in the State. His cattle trails to the rail heads were followed by smaller ranchers on their drives. The Barn is the remaining syi»bol of Goodnight's famous Rock Canyon Ranch and was constructed by his hands in 1871. The Barn is constructed of limestone blocks and is in a state of disrepair. The Southern Colorado Conservancy District is actively pursuing short range restoration plans with Valco. It is the district's long range intent to see the Goodnight Barn fully restored. D.
