SOUTHWEST QUADRANT ANNEXATION MASTER PLAN
PUEBLO, COLORADO
I. INTRODUCTION
A. PURPOSE
The Southwest Quadrant Annexation Master Plan is in response to the Municipal
Annexation Act of 1965 (Section 31- 12- 105[l][e], CRS [1988 Cum. Supp.]).
Compliance of this act requires that prior to completion of any annexation, a
municipality shall have in place a plan that generally describes proposed public
facilities, utilities, and land uses within a three -mile limit from current City
boundaries. Section 12 -5 of the Charter of Pueblo authorizes the preparation of a
master plan for the physical development of the City. The Department of Planning
and Development is charged with the responsibility of conducting such long -range
planning activities for the City of Pueblo. It is the goal of long -range master
planning to provide a framework which will guide development in a consistent
manner. Individual annexation and development decisions should be made according
to criteria that best suits the overall goals of the City.
The Southwest portion of the City consists primarily of newer residential
subdivisions including El 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 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 statues.
B. OBJECTIVE
This annexation master plan will serve as the official "three -mile area plan" for
the Southwest Quadrant. It does not supersede the 1980 Pueblo Regional
Comprehensive Development Plan, except insofar as the Three -Mile Plan shall be
used to identify proposed land uses in that area defined as the "proposed urban
extension area" within the 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 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.
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.
- 1 -
C. ASSUMPTIONS
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 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).

II. ANNEXATION REQUIREMENTS
PREFACE
This plan is designed to conform with the Municipal Annexation Act of 1965 (Part I
of Article 12 of Title 31, CRS) amended by Senate Bill 45 (1987). This Act
requires a municipality to develop an annexation master plan describing proposed
public facilities, utilities, and land uses within a three -mile limit from current
City boundaries.
A. COLORADO ANNEXATION REQUIREMENTS
Senate Bill 45 was passed in the 1987 Session of the Colorado General Assembly.
The following requirements apply to all municipal annexations requested after
May 28, 1987.
1. Development Eligibility (CRS Title 31 -12 -104)
The perimeter of the area proposed for annexation must have no less than one -sixth
contiguity with the annexing municipality. Contiguity may be established by the
annexation of one or more parcels in a series, completed simultaneously, and
considered together for the purposes of public hearing requirements. Contiguity
is not affected by the existence of a platted street or alley, a public or private
right -of -way, a public or private transportation right -of -way, and public lands
whether owned by the State, the United States, or an agency thereof (except
County -owned open space), or a lake, reservoir, stream, or other natural or
artificial waterway between the annexing municipality and the land proposed to be
annexed.
Municipality boundaries shall not be extended more than three miles in any
direction from any point of such municipal boundary in any one year. Such
three -mile limit may be exceeded if it would have the effect of dividing a parcel
of property held in identical ownership, provided that at least 50 percent of the
property is within the three -mile limit. Such three -mile limit may also be
exceeded for the annexation of an enterprise zone. The area within the Southwest
Quadrant which is within an enterprise zone is depicted in Map III.
2. Annexation Master Plan (CRS Title 31-12-105[l]-[e])
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.
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:
- 5 -
a. the present and proposed boundaries of the municipality in the vicinity of the
proposed annexation;
b. the present streets, major trunk water mains, sewer interceptors and outfalls,
other utility lines and ditches, and the proposed extension of such streets
and utility lines in the vicinity of the proposed annexation;
C. the existing and proposed land use patterns in the areas to be annexed;
d. a copy of any draft or final pre- annexation agreement, if available;
e. a statement setting forth the plans of the municipality for extending to or
otherwise providing for, within the area to be annexed, municipal services
performed by or on behalf of the municipality at the time of annexation;
f. a statement setting forth the method under which the municipality plans to
finance the extension of the municipal services into the area to be annexed;
g. a statement identifying existing districts within the area to be annexed; and
h. a statement on the effect of annexation upon local public school district
systems including the estimated number of students generated and the capital
construction required to educate such students.
B. CITY ANNEXATION REQUIREMENTS
This section describes general guidelines to be followed by those persons
(hereinafter referred to as the Petitioner) wishing to petition the City of Pueblo
for annexation. The minimum requirements the Petitioner must meet are:
• The proposed annexation is a logical extension of the City's boundary and
municipal services; and
• 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:

2. Drainage Plan
The Drainage Plan submitted by the Petitioner shall be in accordance with the
Pueblo Storm Drainage Criteria Manual then in effect. This Plan must be
certified by a licensed Professional Engineer competent in the field of surface
water drainage engineering and registered in the State of Colorado.
The Drainage Plan shall address on -site and off -site surface water drainage, as
well as the effects of the proposed development upon downstream properties and
existing drainage facilities. Associated impacts identified in the Drainage Plan
will be mitigated through surface water drainage improvements financed by the
Petitioner. Stormwater detention facilities, designed and constructed in
accordance with the Manual, may be used to mitigate the increased runoff due to
development. The Drainage Plan shall include a phasing plan outlining the order
of necessary drainage improvements.
3. Sanitary Sewer Report
The Petitioner shall prepare a Sanitary Sewer Report in accordance with criteria
specified by the Director of Public Works. -This Report shall be supported by
studies and reports prepared by a licensed Professional Engineer.
The Report shall address the needs of the entire sewer drainage basin. This basin
will be designated by the Director of Public Works. The existing wastewater
system and the impact on that system by the proposed development shall also be
addressed. Any impacts by the proposed development shall be mitigated by the
Petitioner through sanitary sewer improvements financed by the Petitioner. The
Sanitary Sewer Report shall provide a phasing plan for anticipated improvements.
In some cases, the Petitioner will be required to install oversized sanitary
sewers in the PMP area. These oversized sanitary sewers would serve future
development outside the PMP area, but within the sewer drainage basin. A Sewer
Participation Cost Recovery Agreement may be entered into between the Petitioner
and the City. The Petitioner may then be reimbursed for the oversize cost by a
newly benefitted Property owner when any part of the benefitted Property within an
approved subdivision is connected, directly or indirectly, to such oversized
sewers located within the PMP area.
If the Petitioner constructs sewer improvements downstream from the master plan
area which will serve future development outside the master plan area but within
the .sewer drainage basin, the Sewer Participation Cost Recovery Agreement shall
include provisions so that the Petitioner may be reimbursed for a pro -rata share
of the costs of construction of such downstream improvements, plus interest, by
the benefitted Property owner when any part of the benefitted Property is
connected, directly or indirectly, to such sewers.
The Sewer Participation Cost Recovery Agreement shall be in conformity with the
City's then existing ordinances and shall be approved by City Council.
a. Sanitary Sewer Report Criteria
The following criteria will provide guidelines for the planning and design of
sanitary sewers. These guidelines shall include planning criteria and minimum or
maximum controls of sewer design and construction. However, in unusual
circumstances or where special conditions dictate, certain deviations from the
standard criteria may be directed or approved by the Director of Public Works.

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
=Om
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;

These plans analyze the main water sources, both ground and surface, for Pueblo
County. Wastewater facilities are examined; point and non -point pollution sources
are assessed; methodology and results of water tests are documented; and stream
segments are analyzed. Surface watercourses included are:
a. the Arkansas River -- Segments A, B, and C,
b. the Fountain Creek,
c. the St. Charles River -- Segments A, B, and C,
d. Greenhorn Creek -- Segments A and B,
e. Six -Mile Creek, and
f. the Huerfano River.
The 1987 208 Plan Update reviews point source pollution, sludge production, and
wastewater disposal by the City and outlying sanitary districts.
3. General and Engineering Geology of the Northern Part of Pueblo, Colorado
This Geological Survey Bulletin 1262 was prepared by Glenn R. Scott in 1969. This
document locates bedrock formations and surficial deposits for Pueblo County. The
bulletin identifies 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:
- 14 -
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.
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 improvement and construction by the Board in its continuing program of
water distribution. The purpose is to determine the adequacy of the Pueblo Water
Distribution System in satisfying present and future water needs through the Year
1985. The report provides a general guideline for projections made through the
Year 2000 and contains area development studies to determine present and estimated
future population distribution within the service area. Estimates of water
demands and predicted distribution demands on the system are also analyzed.
In 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
This engineering report was prepared by Sellards and Grigg, Inc., in 1971. 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
- 15 -
b. analysis of the existing wastewater treatment plant and recommended
improvements to correct present deficiencies and to provide capacity for
future needs.
The Department of Public Works for the City of Pueblo is currently updating this
report.
4. City of Pueblo Urban Parks and Recreation Recovery Action Program
The City of Pueblo Urban Parks and Recreation Recovery Action Program (UPARR) was
prepared by the Pueblo Regional Planning Commission and adopted by City Council in
1981. The UPARR assessed the physical inventory, the rehabilitative capability,
and the concerns of the City of Pueblo Parks and Recreation Department.
This federally funded program was designed to help physically and economically
distressed urban areas improve recreational opportunities. The conclusion of this
report states that Pueblo's physical parks system is evidence of a firm foundation
for providing the open spaces and services needed and requested by its
population. Recent emphasis to provide parks on the neighborhood level has had
positive results, but future planning should consider more strongly the need for
quality design, construction, rehabilitation, renovation, operations, maintenance,
and the need for the development of additional City -wide facilities.
C. TRANSPORTATION
1. The Year 2000 Transportation Plan Report
The Year 2000 Transportation Plan Report, January, 1981, was prepared by the
Pueblo Area Council of Governments' Urban Transportation Planning Division,
Colorado Department of Highways Division of Transportation Planning, in coopera-
tion with the U. S. Department of Transportation Federal Highway Administration.
The report is an end - product of a process that began with an analysis of the
existing transportation system, progressed through development of a long -range
plan, and evolved into a continuing monitoring phase.
The Plan objectives are:
a. Identify transportation system needs associated with revised projections of
long -range growth factors for the Pueblo Urbanized Area;
b. Adopt a revised transportation plan for the Pueblo Urbanized Area with a
long -range planning horizon for the Year 2000.
c. Program transportation system improvements consistent with long -range
projections of funding availability; and
d. Perform a system level evaluation of social, economic, and environmental
impacts of alternative land use and transportation plans.
This plan is incorporated, in its entirety, as the Transportation Element of the
adopted Comprehensive Plan.
- 16 -
In the Southwest Quadrant The Year 2000 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 proposed
Bandera Boulevard, and the construction of a new roadway between Red Creek Springs
Road to La Vista Hills Road (See Map IV). This Plan and the Year 2010 Plan,
anticipated to be completed in 1989, are statements of present policy toward
future needs. The Year 2010 Plan will reflect new development trends, new
technologies, and changes in travel behavior. Employment, population, and
dwelling units will be projected for 139 traffic zones and seven traffic
generators. Trip generation data will be based on projected dwelling units and
employment. This data will be loaded onto collectors, minor arterials, principal
arterials, expressways, and freeways. The system will then be analyzed for
deficiencies.
2. Analysis District Evaluation To The Year 2010 (by Traffic Zone)
The Pueblo Analysis District Evaluation To The Year 2010 (by Traffic Zone) was
prepared in December of 1984 by the Pueblo Regional Planning Commission. This
report is part of the "Urban (3 -C) Transportation Planning Process" administered
through the Urban Transportation Planning Division (UTPD) of the Pueblo Area
Council of Governments (PACOG). The report is in support of the transportation
network analysis conducted by agencies involved in preparation of the "Year 2010
Transportation Plan."
Projections of population, dwelling units, and employment are provided for the
Years 1990, 2000, and 2010. One hundred and thirty -nine (139) traffic zones in
the Urban "3 -C" Analysis Area and 34 traffic zones in the non -urban area of Pueblo
County have been examined.
The Urban (3 -C) traffic zones were grouped into 11 analysis districts for the
purpose of this report. Each zone was then examined as to its degree of develop-
able land, stability of environment, activity type (residential, commercial, or
industrial), predominant age of structures, and historical change in population.
Population predictions were then assigned a share of expected change.
The traffic zones were analyzed as to their future growth and transportation
needs. Information pertinent to the Southwest Quadrant has been included in the
"Transportation Network" section of this report.

SOUTHWEST QUADRANT ANNEXATION MASTER PLAN I IV
MUM
IV. 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. Recent annexation and
development proposals indicate that a substantial portion of new residential
construction will occur in the Southwest Quadrant. Proper planning of this
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 resulting from incompatible development. It is further
intended that by identifying the area's present resources -- natural and man-
made- -the suitable preservation or utilization of these resources will allow for a
carefully developed community.
This plan is designed to meet the requirements of Senate Bill 45 (1987). This
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 (CRS Title 31- 12- 105[1][e]).
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 and does not supersede the
Pueblo Regional Comprehensive Development Plan, except insofar as the Three -Mile
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 boundary of this study area extends three miles 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 Map II);
and
(2) the rural remainder of the study area which will not be master planned since
it is not anticipated that urbanization will occur in this area within a
12 -month period following the adoption of this plan.
The primary components of this plan include the identification of existing and
proposed major transportation corridors, the anticipated land use around these
- 19 -
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 are 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 from those roadways that are long -range planning 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 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.
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, Bandera Boulevard and 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 Level of
Service "C," as defined in 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 feet; this would
include a 125 -foot roadway ROW and a 25 -foot trail ROW. The roadway would be a
minimum of four lanes with five to six lanes being required at the intersection of
major transportation corridors, depending upon projected traffic volume. Public
and private access onto these roadways would be strictly controlled as per the
Colorado State Highway Access Code The two opposing lanes of traffic would be
separated by a median with a minimum width of 20 feet. 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, may be required
to ensure compatibility of residential development and traffic noise. These
roadways should be constructed to include a pedestrian sidewalk on one side and a
trail within the 25 -foot 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 E XTENSION 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
- 22 -
It is anticipated 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 traffic noise has on human activities. These guidelines are
imposed on those roadways utilizing Federal funding. If traffic noise computer
modeling indicates that noise - abatement measures are necessary, construction of
noise barrier walls and /or non - construction techniques are considered.
Non - construction techniques include: prohibition or time restrictions on certain
vehicle types (trucks), exclusive land designation, modifications to the speed
limit, and increased setbacks for construction.
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. Some 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 habitation by wildlife (See Map VII). Water augmentation law may impact
extraction plans which could result in exposed groundwater, such as these lakes,
and may impact current and future reclamation plans of those areas that contain a
high groundwater table. Legislation is currently pending regarding the
"grandfather" 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.
C. DEVELOPMENT GUIDELINES
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 twenty
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 between single - family residential (R -1, R -2) and commercial
(B -1, B -2, B -3) land uses should occur.
(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 within 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.
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 Area
(a) All mineral resource extraction areas adjacent to residential units shall
be required to provide properly engineered noise buffers between the
extraction area and the residences. The buffers must meet a design
standard, to be established by the City of Pueblo.
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 stations be central to their
service area. No point should be further than one and one -half miles from the
station. Additional fire stations will be required to provide protection to the
proposed urban extension area at build -out. The exact locations of new fire
stations have not been investigated, as these locations will be dependent upon
where development takes place, new road construction, number and density of new
buildings, and other factors which may affect response time.
j. Schools
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 El Camino Subdivisions.
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 (Board of Water Works Rules
and Regulations, October 18, 1983).
a. Neighborhood Park
A neighborhood park shall be developed on a minimum of five acres of land
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. Dedicated
parkland shall be located, when possible, adjacent to school district facilities
to share use. Dedication of drainage ways, steep slopes, or other "nondevelopable
land" for use as parks 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 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.
In the case that development on a floodplain is to be considered, a flood hazard
development permit shall be obtained. The Flood Hazard Development Permit must
demonstrate that the encroachment shall not result in any increase in flood levels
during the occurrence of the base flood discharge. Any development within the
floodplain shall be in accordance with the City Code of Ordinances, then in
effect.
- 29 -
In addition, the terraced slopes south of State Highway 96 are unique geologic
formations. 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 right -of -way and the extension of
those trail corridors through their development. Alternately, they may be
required to pay a fee towards construction of the master trails system. These
trails shall be identified by the City of Pueblo's Bicycle System and Trails Plan,
then in effect. The trails and bicycle lane system should be located along major
roadways, natural scenic areas, river floodplains, arroyos, parks and school
locations, watercourses, and central commercial centers. All trails shall be
constructed pursuant to standards set forth by the Bicycle System and Trails Plan,
then in effect.
Map 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.

V. ENVIRONMENTAL ANALYSIS
PREFACE
The purpose of this review is to provide an understanding of current environmental
conditions, identify potential hazards, and determine the potential for mineral
resource extractions in the 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 will also be addressed. Section B, Environmental
Constraints, identifies potential hazardous areas and mineral resource reserves.
A. ENVIRONMENTAL INVENTORY
1. 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; the most familiar found
in the Southwest Quadrant include sand, gravel, and clay.
In addition, since sedimentary rocks are produced by interactions of the
hydrologic system and the earth's crust, they record the history of physical and
biological events on the earth. From this record, we are able to interpret
ancient mountain building and specific erosion patterns that may impact
development.
The bedrock in the 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, 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 feet thick.
Their 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 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.

2. Surficial Geology
Some of the bedrock in the Southwest Quadrant is covered by surficial deposits.
This material is composed of clay, silt, sand and gravel, and other substances
which have been deposited by running water and wind. These surficial deposits
overlie the sedimentary bedrock except where faulting, folding, or erosion have
exposed bedrock sections. Surficial deposits in the 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 X 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.

3. Landforms
Landforms refer to the topographical characteristics in a specific area. They
result from the interaction of three factors -- structure, process, and stage.
Structure refers to an existing surface or geologic structure found in the area.
Process is the natural and chemical erosional element which modifies the
structure. Stage indicates the length of time in which the erosion takes place.
Elevation in the study area ranges from 4,705 feet above sea level at the
Arkansas River to 5,344 feet 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.
Physical characteristics of the Southwest Quadrant are illustrated on Map XI;
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 XII). These basins
are south -bank tributaries to the region's primary watercourse - -the Arkansas
River. 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
A floodplain is that flat area along the course of a river or stream that is
naturally subject to flooding. A 100 -year floodplain has a one - percent chance of
flooding in any one year, or once every 100 years. The Arkansas River and the
Goodnight Arroyo are classified as 100 -year floodplains (See Map XII).
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 is currently
channelizing and constructing flood levees on the Fountain Creek north of the
Arkansas River /Fountain Creek confluence. The levee project is anticipated to be
complete 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 square 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.
Salt Creek joins the Arkansas River in the southeast corner of the City of
Pueblo. Salt Creek drains an area of 37.2 square miles. The Creek originates in
the foothills and empties into the St. Charles Reservoirs Nos. 2 and 3. From the

Reservoir, the flow crosses 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 Nos. 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.
5. Wetlands
Wetlands refers to those areas that are inundated by surface water or
groundwater. Wetlands generally include swamps, marshes and bogs, and similar
areas such as sloughs, potholes, wet meadows, sewer overflows, mud flats, and
natural ponds.
A 0.5 square 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 feet below the land surface.
The principal cause of the shallow water table is the high water level of Lake
Minnequa. Seepage from the reservoirs (St. Charles Reservoirs Nos. 1, 2, and 3),
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 XIII locates
regions where the water table is: (1) less than six feet; (2) less than ten
feet; (3) less than 20 feet; and (4) less than 30 feet 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,
Waterlogging in an Alluvial Aquifer near Lake Minnequa, the City implemented an
"Acquisition /Relocation" Program for the residents in the waterlogged "less than
six feet to the water table" area. The program utilized Community Development
Block Grant Funds; to date all but one residence has been acquired and the
occupants relocated.
6. Climate
The Pueblo region is located in the transition zone between the temperate and
hot, arid climatic regions. The climate is characterized by abundant sunshine,
low relative humidity, light to moderate winds, large daily temperature
variations, and light precipitation. Average annual precipitation is
approximately 11.6 inches.
Temperatures in the summer reach 90 degrees or 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.

7. Flora and Fauna
Plant and animal associations are groups of species co- existing in a
complementary fashion. Groups of associations are called communities. A biotic
zone consists of an association of communities. These zones are defined by soil,
moisture, climate, and the biotic history of the area. These conditions
determine the nature and distribution of plant and animal habitat.
The Southwest Quadrant study area is contained within the "Plains" biotic zone.
This zone characteristically lies between 3,500 and 5,500 feet 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; (b) Woodlands of the River Bottoms; and (c) Woodlands of the Foothills
and Plains as described below:
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.
c. Woodlands of the Foothills and Plains -Pinon Pine and /or One Seed and Rocky
Mountain junipers, along with an occasional Ponderosa Pine, Mountain Mahogany,
Skunkbrush, Sumac, and Gambel oak. Principal grasses include Indian rice
grass, Needle grasses, Big and Little blue stem, Blue grama, Sideoats grama,
and Western wheatgrass.
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. Habitat is valued in terms of food sources,
vegetative cover, water availability, shelter, and breeding grounds. Different
animal species relate to different habitat.
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
protected and that endangered species are preserved from further urban
encroachment. Zoning for parks and recreational open space is encouraged in the
floodplain to help facilitate this preservation.
Disturbance to or extinction of any one habitat, plant, or animal species can have
an impact on other species. Preservation and protection of habitat and species is
imperative in maintaining the integrity of native plant and animal populations.
- 45 -
8. Water Quality
The Southwest Quadrant consists of three drainage subbasins (See Map XII). The
subbasins are tributary to the Arkansas River Basin. To ensure the quality and
acceptability of Colorado's waters for beneficial use, water quality standards and
classifications have been adopted by and for the waters of the State, including
the Arkansas River.
The mainstem segment of the Arkansas River within the study area is referred to as
the Middle Arkansas River, Segment 2, by the Section 208 Water Quality Plan. It
is located between the outlet of the Pueblo Reservoir and a point immediately
above the confluence with the Wildhorse /Dry Creek Arroyo and is classified as a
Class I Recreation and Cold Water Aquatic Life, and a Class II Agriculture and
Domestic Water Supply 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
Dissolved Oxygen
Un- ionized Ammonia
Fecal Coliform
Suspended Solids
Life
Result
Consistently High
Within Safe Limits
Within Safe Limits
Exceeds recommended
limits for Cold Water Aquatic
These conditions support the use of this segment as a Primary Contact Recreation- -
Aquatic Life -- surface water supply area.
The 1987 Section 208 Plan Update 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 stormmater 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.
9. Air Quality
Air quality in the Southwest Quadrant, as in the entire Pueblo County region, is
in compliance with Federal standards set by the Clean Air Act (1963) and its
subsequent amendments. Recent clean air programs and the CF &I Steel Corporation
production cutbacks resulted in vast improvements in Pueblo's air quality.
- 46 -
Air quality is determined by measuring particles suspended in the atmosphere. One
way of measuring the supsended particles is by monitoring the Total Suspended
Particles (TSP's). In October, 1987, a new system, Particulate Matter 10 Microns
or less (PM -10) was installed by the Pueblo City- County Health Department that
also monitors suspended particulates. Test results have indicated a steady
increase in air quality for the Pueblo region. Pueblo is considered "low
priority" as a result of its consistent compliance with Ambient Air Quality
Standards and thus is only required to continue regular air quality. The 1988
PM -10 results indicate the Pueblo region has a 14 percent chance of noncompliance
with Federal Ambient Air Quality Standards. Those areas with a 20 percent or
greater chance of noncompliance must have a State Implementation Plan in place.
This plan outlines procedures directed at decreasing pollution and thereby
decreasing the chance of noncompliance.
There are no monitoring stations located within the Southwest Quadrant.
Currently, TSP and PM -10 monitoring stations are located in Downtown Pueblo. Due
to the concentration of activity, this area is considered to register a "Worst
Possible Case" scenario of particulate readings.
It should be noted that new development may cause a short -term increase in
suspended particulates as a result of cut and fill, grading, and other
construction activities. Such activities may require the issuance of an emissions
permit from either the State or local Health Department.
Carbon monoxide, of concern to several Colorado cities, has not reached severe
levels in Pueblo. The City is thereby not required to monitor this particular
pollutant.
B. ENVIRONMENTAL CONSTRAINTS
Areas in which environmental hazards exist may not be the optimum areas for land
use development projects. Those areas where steep or unstable slopes,
floodplains, erodible soils, large arroyos, or waterlogged lands exist are
fragile environmental zones and can place constraints on development.
Prior to any new development, an environmental analysis should indicate areas of
environmental sensitivity. Mitigating measures should then be utilized in
planning and construction.
The severity and location of various environmental hazards and of mineral
resource areas within Pueblo County were computer- mapped via a program called
IMGRID Analysis (Improved Grid). This program was developed by the Department of
Architecture of Harvard University's School of Design.
The potential hazards analyzed for Pueblo County and included in this report
include: (1) Floodplain Hazards and Drainage Needs; (2) Wildfire Hazards;
(3) Geologic Hazards: (a) Unstable Slopes; (b) Mud Flow /Debris Fans; (c)
Expansive Soils and Rocks; (d) Ground Subsidence; (e) Seismic Effects; and (f)
Erosion; (4) Wetlands; (S) Mineral Resource Areas; and (6) Environmental Hazards
Composite.
- 47 -
The following text describes potential hazards in the Southwest Quadrant:
1. Floodolain Hazards and Drainage Needs
A floodplain is an area along the course of a river or stream that is naturally
subject to flooding. A floodplain is described by Colorado statutes
(24 -65.1- 103[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 Goodnight Arroyo, and Salt Creek are classified as 100 -year
floodplains (See Map XII).
Fine silt, mud, and sand are deposited on these floodplains when water volume is
high. During each high water stage, these deposits (called alluvium beds) become
thicker and wider. Simultaneously, erosion creates steep, unstable river banks.
According to Federal law, the floodplain should be reserved in order to discharge
the base flood without cumulatively increasing the water surface elevation more
than one foot.
It is the goal of Pueblo's zoning and development procedures to protect
floodplains in accordance with this law. Development in the floodplain is
restricted unless technical evaluation demonstrates that encroachments shall not
result in flood levels (City Ordinance Title XVII Section 9). Construction on
fringe areas should require special floodproofing measures found in Title XVII of
the Zoning Ordinances for the City of Pueblo.
Prior to development, a master drainage plan must be prepared which would discuss
natural flows, additional hydraulic flow generated by new developments, and
mitigating measures necessary to ensure adequate drainage. Improvements might
include holding ponds, diversion channels, check dams, drainage pipes, gutters,
and channel boxes. Hydrologically, the results are similar but the cost and
amount of land necessary for these improvements varies.
2. Wildfire Hazards
A wildfire is any fire that is burning out of control including brush fires,
forest fires, grass fires, and structure fires. A number of 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 over and above standard fire prevention development
policies need 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; Expansive Soils and Rocks; Ground
Subsidence; Seismic Effects; Erosion; Radioactivity (no hazards defined by
IMGRID); Rockfalls (no hazards in the area); Landslides (no hazards in the area);
and Avalanches (no hazards in the area).
a. Unstable Slopes
An unstable slope is an area where gravity can cause loose dirt, gravel, or any
surface materials to move downhill. Natural and man -made slopes occur from
weathering, erosion, filling or cutting away existing slopes, or altering natural
drainages. River floodplains create a natural unstable slope on channel banks.
Potentially unstable slopes within the Southwest Quadrant have been identified on
Map XIV. These slopes can be dangerous as they are presently in a delicate state
of balance. 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
A mud flow (also called earth flow or debris flow) is a rapid movement of a mass
of earthen mud. Mud flows occur chiefly in dry canyons or arroyos in semiarid
regions and result from cloudbursts or snowmelt. A debris fan is a deposit of
gravel, mud, silt, small rocks, and other substances shaped like a triangle and
formed where a watercourse enters a larger valley. Debris fans are closely
related to mud flows and are sometimes associated with one another. Building on
or in the paths of a mud flow or on a debris fan is extremely hazardous. Mud
flows can be unpredictable and seemingly minor factors can trigger the flow.
Moderate mud flow and debris fan hazards are found chiefly in the proximity of the
floodplains.
The "IMGRID Debris Flow, Mud Flow, and Debris Fan Hazards" Map was generated by
the extraction and compilation of soil, geology, intermittent stream, and alluvium
data bank components. Areas possessing only one of these components are located
within the study area. They are indicated on Map XIV. 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.
c. Expansive Soils and Rocks
Expansive soils and rocks means soils and rocks which contain clay and which
expand to a significant degree upon wetting and shrink upon drying. Clay is
composed of flat, microscopic plates. Layers of water molecules form between
these plates. As more water is added, the water molecules push the clay plates
further and further apart. This occurs throughout the clay deposit and causes an
increase in the size of volume which in turn creates swelling pressures. When the
clay deposits dry out, the reserve is true and the deposits will shrink in size.
Building can take place in areas containing swelling clay deposits. Professional
soil engineers and engineering geologists should become involved before the design
of a structure is complete. Foundation design, water drainage, landscaping, and
interior finishes are considerations for all development projects. Swelling soils
are common in the study area. Much of the study area's soil ranges from low to
high in its expansive properties. Several areas have been identified as having
very high expansive properties (See Map XIV).
- 49 -
d. Ground Subsidence
Ground subsidence refers to the downward displacement of surface material. Ground
subsidence can occur naturally or by man -made processes, such as:
(1) 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 XIV
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.
e. Seismic Effects
Seismic effects refer to the degree which earthquakes or an underground nuclear
detonation impact on the environment. An earthquake or tremor in an area can
increase the possibility of geologic hazard occurrence. Landslides, rockfalls,
unstable slopes, and flood potential would be greatly affected. These elements
were compiled into the number of potential seismic hazards present per cell.
Three hazards were identified by the IMGRID Program. In the Southwest Quadrant, a
few scattered cells exist which contain only one seismic hazard. These hazardous
areas should be noted but should not be considered a severe constraint to
development.
f. Erosion
Erosion is not listed in House Bill 1041; however, the authors of the IMGRID
Environmental Analysis felt that the high economic and environmental costs of soil
displacement constitutes both a long -range hazard and a resource loss.
Erosion is the end - result of a culmination of factors such as vegetative and
man -made cover types, gradient, the chemistry make -up of soil, weathering,
overgrazing, and other man - caused disturbances.
The problem of erosion in the study area ranges from non - existing to severe or
losing anywhere from 0 to 200 tons of soil per acre per year. Areas experiencing
the worst soil losses are 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.
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. Erosion sensitive areas
are located on Map XIV. 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. The Manual is expected to be adopted in 1989.
- 51 -
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. Wetlands
Wetlands, as described in the Environmental Inventory, are a constraint to
development when there exists a potential for water damage to man -made
structures. A waterlogged area, having a water table of six feet or less, has
been identified just south of Lake Minnequa. This area is within City limits and
is therefore not specifically addressed in this master plan. Areas to the south
of the City limits and in the West Park area with a water table of between six and
twenty feet below land surface are within the quadrant study area (See Map XIII).
5. 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 (See Map XV). Deposits of sand and gravel
are abundant near the Arkansas River.
Prior to extraction of any resources, a thorough analysis must be made of the
impacted area. The following must be addressed in this analysis:
a. Importance of diverting future developments to areas which will not interfere
with extraction of minerals.
b. The need to permit extraction or exploration of minerals, unless extraction or
exploration would cause significant danger to public health and safety.
c. A comparison between the economic value of the minerals present against the
economic value of the proposed development.
d. Procedures proposed for assuring that exploration and extraction of a mineral
shall be carried out in a manner which will cause the least practical
environmental disturbance.
Permits for extraction and processing of sand and gravel and exploration of
natural resources are issued by the County Planning Commission.

6. Environmental Composite
The Southwest Quadrant is relatively stable. A composite of various environmental
factors is graphically depicted of those areas determined to be "environmentally
sensitive (See Map XIV)." These areas will require particular attention in the
event of new development.
The Arkansas River floodplain includes erosive and unstable slopes. These slopes
cannot withstand intensive development and should remain as a natural buffer
between the Arkansas River and commercial or residential development. Aside from
these slopes, no extremely hazardous environmental conditions exist. Constraints
posed by soil conditions, erosion, floodplains, slopes, debris fans, and shallow
water tables can be mitigated through sound structural engineering and landscape
design.

VI. INFRASTRUCTURE PLANS -- EXISTING AND PROPOSED ROADWAY AND UTILITY SYSTEM
PREFACE
The existing infrastructure of an area and its ability to expand is crucial in
attracting and supporting new growth. Annexation and the subsequent
development of new areas, whether residential, commercial, or industrial, will
impact the existing infrastructure and will likewise result in the extension
of municipal services.
This section will describe the existing transportation routes, water and waste-
water systems, electric and gas services, telephone services, and cable
television systems. An analysis will address the ability of these services to
expand and support new development.
A. TRANSPORTATION NETWORK
The major transportation routes serving the 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 minor 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. Red Creek Springs Road, Hollywood Drive, Jones Avenue, and St. Clair
Avenue are minor arterials.
Residents of the Southwest Quadrant and public officials have expressed
concern over several primary access roads. They are:
1. 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 (E1 Camino Parks
Subdivision), thereby further impacting the roadway.
2. Bridle Trail, currently classified as a collector, will eventually bridge
the Arkansas Valley Conduit and serve the El Camino and E1 Camino Parks
Subdivisions. No specific date for the extension has been identified by
the developer. Although this extension will provide a much needed second
entrance into El Camino, it will only minimally reduce traffic on
Encino Drive due to the layout of the subdivision.
- 57 -
3. 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 -Mile Annexation Plan, of this report.
Transportation planning in the City of Pueblo is accomplished with the aid of
three transportation studies: (1) The Analysis District Evaluation to the Year
2010 (2) The Year 2000 Transportation Plan; and its successor, (3) The Year 2010
Transportation Plan (to be adopted in 1989). The Year 2000 and Year 2010
Transportation Plans utilize computer modeling (TRANPLAN) and actual vehicle
counts to determine the degree of efficiency of the current transportation
network. Any deficiencies are analyzed and the effect of alternate roadways are
examined.
These Transportation Plans employ statistics from the Analysis District Evaluation
To The Year 2010. This plan provides 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, and
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 right -of -way and
future roadways align into a planned framework, the Southwest Quadrant Three -Mile
Annexation Plan, Section IV of this report, proposes future primary roadway
corridors. These corridors are proposed now, regardless of immediate need, so
that the City's transportation system remains cohesive.
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 Easter
Colorado drainage basin of the Arkansas River. Water service within the Southwest
Quadrant is currently provided primarily by private wells and by the Board of
Water Works, the primary purveyor of water for the City of Pueblo. Two private
water associations (Pueblo Gardens and Sunset View Water Associations), which are
at their service capacity, serve a few households in the West Park area. 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 diverted from the Arkansas River enters the Whitlock Treatment Plant. This
plant became operational in 1977. The treatment process employed by the Board of
Water Works includes flocculation, sedimentation, and a filtration process.
Testing on a continual basis ensures Pueblo of high quality water through rigid
quality control methods. The plant has the capability of serving a population of
158,000. There is no further opportunity for expansion at the Whitlock Plant.
The Board of Water Works does own a plant site downstream from the Pueblo Dam. If
facility expansion was necessary, a "peaking plant" could be constucted on this
site. Such a facility would supplement the existing plant during peak summer
months and would likely be shut down during winter months.
Treated water from the Whitlock Treatment Plant is transferred to the distribution
system. This system is divided into pressure zones in order to maintain water
pressures within practical limits. The 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 Map XVIII).
In order to service those areas in the 8000 Zone, including a part of the proposed
E1 Camino Parks Subdivision, major improvements will have to be made. Developers
may be required to install, at their expense, a pumping station at the
Westmoor storage tanks and an additional storage tank at approximately the 5,300
foot elevation level.
Development in the 10000 Zone will necessitate installation of additional
equipment. The Board of Water Works has no plans at this time to pursue such
improvements. It is proposed that the La Mesa Encantada Subdivision, atop the San
Carlos Mesa, will be serviced by a private water main from the Westmoor 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 West 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 signed, the applicant has 120 days in which to act while
being guaranteed the established fees. After this time, fees will be adjusted to
current levels. The plant water investment fee is charged to customers seeking
service through new, additional, or increased size of meter or number of units,
and became effective January 1, 1989, as shown on Table V.
- 61 -
- 62 -
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. The unit cost program is described in Table VI.
If an applicant requests that the Board install a main extension inside Permit
Area "A ", the applicant will be charged the unit cost per foot of main extension,
regardless of size. The cost of asphalt pavement or concrete replacement shall be
paid by the developer /customer.
It should be noted
scheduling of water

additional costs are
that the workload of the Board does not allow for any
main installation. There is a one -year completion deadline
time will be granted. Furthermore, the established costs per
refer to the applicant's actual cost to install the water
areas, such actual costs may exceed the outlined costs. Any
the responsibility of the applicant.
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 Water 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 West Park area. Approximately one third
of the West 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).
In 1974, 1976, and 1983, the Pueblo City- County Health Department and the Pueblo
Regional Planning Commission conducted groundwater quality asessments. 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
Govermnments 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 the 19 analyses conducted in July and August, 1987, by the Pueblo
City- County Health Department are reported in Table VII 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 /1 NO3, with the highest
level being 103 mg /l.
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 be caused by Nitrate levels which are significantly below the
Environmental Protection Agency's (EPA's) standard of 45 mg /l. In fact, local
health officials recommend that water exceeding 4.5 mg /l, 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 West 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 are. 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 substantiatated 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.

whether the results reported Nitrate as N or as NO3.
The quality of drinking water in idividual 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, 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.

too numerous to count (TNTC) and are not included in the average.

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), will replace the former facilities. The
new plant will be capable of serving a community of up to 147,900 persons. It is
expected that the plant will be in 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.
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.
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 has been extended to July 1, 1990. Currently, there are
no areas in the unincopporated 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 which pump out and dispose of septic system
and other sewage wastes must abide by City- County Health Department
requirements. They must also meet the receiving wastewater treatment plant's
applicable conditions or disposal regulations.
Pursuant to the Individual Sewage Disposal Systems Act, the Pueblo City- County
Health Department is responsible for licensing septic tank pumpers and
haulers. The license governs tank capacity, safety, and disposal. It is
issued annually and complaints on safety and dumping can result in the
revocation of a license.
.:
When 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.
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 electric power by Centel Corporation (Southern
Colorado Power) and San Isabel Electric Association (See Map XX). Centel Corpora-
tion 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 Centel's service area.
Centel operates an electric -power generating station at 105 S. Victoria Avenue.
Initially, the plant burned coal to generate electric power. The plant currently
burns natural gas as its primary fuel and utilizes oil for peaking generation and
as a backup in the event of natural gas curtailments. The plant complies with all
Environmental Protection Agency requirements. Generation facilities at the plant
consist of two units with a capacity of 8,000 kilowatts each; one unit with
19,000 kilowatt capacity; and five diesel generators, each with a a capacity of
2,000 kilowattts. Centel 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.
Centel purchases approximately 65 percent of its power requirements from Public
Service Company of Colorado under a renewable 20 -year contract.
Centel 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
- 70 -
provides backup power in the event Centel 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.
Centel 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 feet for parallel lines and 100 feet for
single lines. Centel officials state that all requests for electric service in
the study area can be fulfilled with reasonable promptness.
Centel's service policy is found in Section 18 of its rules and regulations
manual. The policy states that an applicant's electric requirements (either for
an individual or a developer) are designated by the company to be permanent,
indeterminate, or temporary. Distribution sytem extension costs are estimated on
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 constuction allowance
determined by Centel. The construction allowance is determined by the type of
service and the customer's estimated electric power demand. The customer's
payment may be partially or totally refunded during a five -year period. After
five years, no refunds will be made. Indeterminate and temporary customers are
required to pay all distribution extension costs and do not receive refunds unless
reclassified as permanent by Centel.
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
Dam. 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 -foot 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, right -of -ways, 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
- 71 -
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.
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
distribition 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. [Jest 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 square 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.

VII. PUBLIC FACILITIES -- EXISTING AND PROPOSED PLANS
PREFACE
Recreation, education, and public protection are community services which maintain
an area's well being, growth, and attractiveness. In turn, growth will increase
the use and the demand for public services and facilities. Public facilities must
be capable of expanding in order to meet this increased demand and still provide
consistent quality and quantity of service.
This section will examine the school, park, fire, and police facilities and
services within the Southwest Quadrant. The impacts caused by development and
expansion capabilities will also be discussed.
A. SCHOOLS
Pueblo County has two public school districts, No. 60 and No. 70. School District
No. 60 is primarily contained within the Pueblo City limits; however, it also
includes land outside city limits. District boundaries are not precisely the same
as City limits in that some "City" children go to "County" schools and vice versa
(See Map XXI). The Southwest Quadrant study area is almost entirely within School
District No. 60 boundaries.
1. 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.
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 E1 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 (8) elementary schools,
three (3) middle schools, two (2) 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 E1 Camino,
many of the elementary schools are nearing capacity (See Table VIII).
In October, 1988, voters in School District 60 turned down a bond issue for new
school construction and facility repairs. School district officials will now
conduct a public survey in an attempt to determine public attitudes and perceived
needs in regard to education. They will then reevaluate the District's
priorities. In 1989 school repairs will be made, where necessary, using capital
reserve monies.

2. School District No. 70
School District No. 70 maintains a total of two (2) high schools, four (4) middle
schools, six (6) elementary schools, and one (1) school -- Beulah School - -which
functions as both an elementary and a middle school. County High, Pleasant View
Middle, and Beulah and South Mesa Elementary Schools serve a very small portion
of the Southwest Quadrant. These schools have adequate room for enrollment
growth (See Table IX).
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. Although it is a rural school district School District No. 70
identifies philosophically with neighborhood schools and additional facilities
would be constructed to meet the demands of growth and development if deemed
necessary in an area.
School District No. 70, through an agreement with Pueblo County, requires that
ten percent of net land in residential developments be dedicated for school sites
- 75 -
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.

3. Detachment and Annexation of School Districts
Detachment and annexation of territory from one district to another is a complex
process. The School District Organization Act of 1965, Section 22 -30 -138, states
that if detachment and annexation is deemed to be worthwhile, then both boards of
education must adopt a resolution to change the boundaries of their respective
districts. This resolution then goes to a joint committee or to the County
school superintendent to be approved. 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.
B. RECREATION
1.
Parks and Recreation
The City of Pueblo has approximately 948 acres of parkland and 1,707 acres of open
space floodplain within its boundaries. Combined, these account for more than ten
percent of total City land. Recreational facilities include a large urban park
- 76 -
(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 as follow:
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 1/2 Mile 2 -25 Acre Min. 4.0 Ac /1,000
Neighborhood Park 1 -1/2 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
eight feet) and length. It is designed to weave
through existing natural /scenic and urban areas, thus
connecting and offering better utilization by
recreational and non - recreational users.
As a home rule city, the City of Pueblo has the authority to own and maintain
property for public purposes. Parkland areas may be acquired through City
purchase, property gifts, through settlement of delinquent taxes, abandonment,
easements, and through land dedication.
Title XII, Chapter 4, Section 7(e) of the City Code of Ordinances, states that
eight percent of land subdivided for residential purposes (exclusive of street
widths) is to be dedicated as parkland. This land can be several small parks or
one large park depending on the needs of the community. If the City Council
determines that said land is not appropriate for parkland dedication, the Council
shall require a cash payment in lieu of land dedication. This payment shall be
equal to eight percent of the fair market value of the land in such subdivisions.
This payment is deposited into a special fund to meet future recreational needs in
the City.
The City Parks and Recreation Department is responsible for the development,
operation, and maintenance of recreational and park facilities. The City
Department of Planning and Development provides professional planning and landscape
- 77 -
design services when needed. Financing new parks and recreational development is
provided through the City's General Fund. The dollars generated by the Colorado
Lottery are deposited into the General Fund and earmarked for "allowable" parks and
recreation projects. Funding is supplemented with State and Federal grants.
The City portion of the study area contains over 500 acres of open space and
recreational land. Table X 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 1980 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, 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.
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 eight feet wide and constructed of asphalt or concrete.
Trails flank the Arkansas River to the Reservoir and the Fountain Creek. Other
paths are located along sections of State Highway 78, Northern Avenue,
Pueblo Boulevard, State Highway 47, U. S. Highway 50 Bypass, and near the
University of Southern Colorado.
It is desirable to plan for multipurpose trails in order that proper right -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.
The Pueblo Bicycle System and Trails Plan will be completed in 1989 by the City of
Pueblo Department of Planning and Development. This plan will thoroughly examine
the existing trails system and will propose logical extensions of the system. The
plan will also examine the trails design, construction, factors, and safety. The
goal of the plan will be 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 Outside City Limits
a. The St. Charles Reservoirs Nos. 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 Dam and Reservoir 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.
The City is divided into eight fire protection zones and one zone at the Pueblo
Memorial Airport. Each is served by a fully equipped fire station. Four stations
serve the Southwest area of the City. They are:
Station No. 3, located at 123 W. 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. Clair Avenue, is equipped with
a 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.
Map XXIII illustrates the respective protection zones.
Once an area is annexed into the City, the City Fire Department becomes
responsible for fire protection in the area. In the event that a new station was
needed, the Fire Department would apply for special funding from City Council. A
new fire station, utilities, a new pumper truck, equipment, and fire fighter
salaries (3 shifts and backup personnel) would initially amount to $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.
mr.-M
2. Wes 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
District's 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 a mutual aid agreement with the City of
Pueblo Fire Department stating that either department will assist the other, upon
request, in the event of an emergency. The West Park District does not provide
medical assistance.
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
1. City Police Department
The Pueblo City Police Department is located at 130 Central Main Street. All
operations are headquartered from 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
$200,000, including three, one - person shifts of officers, backup personnel, and
automobile expenses and repairs (1988 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 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
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 transfers from the
County Sheriff Department to the Pueblo City Police Department.
VIII. CURRENT ZONING AND LAND USE

land uses in both the City and the County. Zoning and
this plan reflect a desire for compatible yet flexible
The Southwest portion of the City is 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 1/2 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
Land in the unincorporated portion of the study area is primarily zoned open space
rangeland. Rural residential zoning is located in the West Park and Stonemoor
Hills areas and immediately west of Regency Park. Areas north and south of
Regency Park are zoned for medium - density residential development. Two small
parcels of public land and one commercial parcel are located along Highway 78
(See Map XXV).
C. LAND USES
1. General
Land uses in the Southwest Quadrant 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 Southside Landfill and the closed Southwest Dump are
located in the unincorporated portion of the study area and are discussed in
detail below under their own subsections.
2. Farmland
The economy of Pueblo County is partially based on the farming and ranching
industry. The U. S. Department of Agriculture (USDA), Soil Conservation Service,
is charged with the responsibility of identifying and locating prime and unique

farmlands. This important farmland program also encouraged the identification of
farmlands of Statewide and local importance. Much of the open rangeland in the
Southwest Quadrant is classified as "Prime Farmland If Irrigated" by the USDA
Soil Conservation Service (See 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 County Landfill
This solid waste disposal site and facility, also known as the Pueblo
Southside Landfill, is located southwest of the City of Pueblo and northwest
of State Highway 78 (See Map XXVII). 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 Waste 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, per the
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 Map XXVII).
The 1988 amendment was precipitated by the fact that the landfill was at or
near its permitted capacity. The intent of the amendment was to allow time
for a replacement landfill site to be permitted and become operational. The
amendment increased the elevation to which solid waste could be mounded,
thereby extending the life of the landfill by approximately 20 months,
assuming the then - current rate of solid waste disposal.
Zupan Enterprises, Inc., handles all facets of landfill operations. A
negotiated agreement between Zupan and the City of Pueblo defines the
operation and has no specific expiration date. If either party chooses to
terminate the contract or close the landfill, four months' notice must be
given to the other party.
The landfill accepts solid wastes (refuse and garbage) but is not permitted to
store nor dispose of hazardous wastes on the premises. A tipping fee,
assessed by the State of Colorado, is charged to all disposing -waste vehicles
and is deposited into a State matching fund. In addition to solid waste,
disposal of vehicle tires is allowed. A separate per -tire tipping fee is
assessed. Tires pose specific problems to landfills due to the amount of room
they take up and due to the fact that the air space retained in them can cause
them to surface once the landfill is reclaimed.
To avoid contamination of nearby water sources, Zupan controls all runoff and
drainage from the property and the City monitors groundwater in the area on a
regular basis. No contamination has been discovered.
Engineering studies of the Southside Landfill which indicated the facility was
nearing capacity caused formal private- sector proposals for sites to replace
e�er�t 1

the Southside Landfill to begin coming forward in 1983. To date, one proposal
has progressed slowly through the permitting process and obtained a COD on
February 16, 1989. A second private- sector landfill application currently
awaits review by the Colorado Department of Health and formal hearings before
local government bodies.
With no assurance that a timely replacement facility would be forthcoming from
the private sector, the City and County of Pueblo resolved in August, 1988, to
collectively locate, acquire, and permit a replacement site. A timetable of
18 months was set for the completion of those tasks. The 1988 COD amendment
should provide the time necessary to either secure a replacement landfill site
through private sector efforts or through a joint City- County effort.
Once a replacement landfill is operational, the Pueblo Southside Landfill will
be closed and reclaimed. A lengthy reclamation period (between 10 to 50
years) may be required because of the very dry area 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 will be extended.

dump site.
The Pueblo City- County Health Department conducted a survey of the Southwest Dump
on September 6, 1978. Approximately 20 holes, 50 yards apart, were punched and
tested for methane in a cross - sectional area of the dump. No methane was found
in any of the samples taken. Although the testing was conducted according to
accepted methods, this test did not guarantee the absence of methane since the
test holes were only to a depth of 3 -1/2 feet. The depth at which the burn
refuse begins is unknown.
5. Valco, Inc.
Valco, Inc., has a special use permit for the extraction and processing of natural
deposits on approximately 262 acres immediately north and south of the Arkansas
River (See Map XVI - -SUP #479). The majority of the Valco property is located
within the Southwest Quadrant proposed urban extension area. In addition, Valco,
Inc., 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. These 40 acres will need to obtain a special use
permit also.
Valco, Inc.'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 medium 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.
