SOUTHEAST QUADRANT ANNEXATION MASTER PLAN
PUEBLO, COLORADO
I. INTRODUCTION
A. PURPOSE
The Southeast Quadrant Annexation Master Plan is in response to the Municipal
Annexation Act of 1965 (Section 31- 12- 105[1][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.
In 1988, the City of Pueblo annexed the U. S. Highway 50 corridor, east from the
City limits to 30 1/2 Lane. This action resulted in the extension of municipal
service boundaries to include the corridor. This annexation, coupled with recent
development proposals, indicates a possible growth trend in the Southeast
Quadrant.
The Southeast 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 statutes.
B. OBJECTIVE
This annexation master plan will serve as the official "three -mile area plan" for
the Southeast 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 Southeast Quadrant. It is designed to be a framework
for development, with sufficient flexibility to be changed as conditions warrant.
The goals of the Southeast Quadrant plan are:
_ GOAL 1: Establish appropriate land use and annexation policies which will guide
development within the Southeast Quadrant. These policies will provide a
standard approach for future annexations and will supplement City zoning
and subdivision regulations.
- 1 -
GOAL 2: Comply with State annexation laws, Pueblo Board of Water Works policies,
and U. S. Government Federal Aviation Administration (FAA) airport
regulations and aircraft recommendations.
GOAL 3: Identify proposed public facilities, utilities, and land uses within the
Southeast Quadrant.
GOAL 4: Provide an inventory of the planning area in relation to the natural
environment, the infrastructure, and the public facilities available.
C. ASSUMPTIONS
1. Development at the Pueblo Memorial Airport Industrial Park (AIP), directly
north of the study area, will continue at or near its historic rate.
2. There will be an increasing need for service industry to support AIP growth
and activity (i.e., restaurants, service stations, lodging, shopping centers).
3. There will be a continuing need for recreational areas (i.e., parks, rest
stops, and natural and bike trails).
4. There is a need to protect the Airport from incompatible development.
D. LOCATION
The Southeast Quadrant contains approximately 37 square miles and encompasses an
area which extends three miles from the existing City limit line adjoining the
Southeast portion of Pueblo, Colorado.
The Southeast Quadrant Annexation Master Plan study area is that area bound on the
north by U. S. Highway 50 -B, on the east by 36th Lane (Colorado State Highway 231)
and the St. Charles River, on the west by U. S. Interstate 25, and on the south by
the Comanche Power generating plant (See Map I).
The term "proposed urban extension area" shall indicate that area between
U. S. Highway 50 -B and the Arkansas River. It is this area which is considered to
be the most probable for annexation due to its proximity to the Pueblo Memorial
Airport and Airport Industrial Park and due to the ability to extend municipal
service into the area. The remainder of the study area including the St. Charles
Mesa communities and the CF &I Steel Corporation is presently served by alternate
potable water suppliers and wastewater treatment services, and has little pressure
to annex into the City.

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 waterways between the annexing municipality and the land proposed to be
annexed.
Municipality boundaries shall not be extended more than three miles in any
direction from any point of such municipal boundary in any one year. Such
three -mile limit may be exceeded if such limit would have the effect of dividing a
parcel of property held in identical ownership, provided that at least 50 percent
of the property is within the three -mile limit. Such three -mile limit may also be
exceeded for the annexation of an enterprise zone. The area within the Southeast
Quadrant which is within an enterprise zone is depicted in Map II.
2. Annexation Master Plan (CRS Title 31 -12- 105[1] -[e
Prior to completion of any annexation within the three -mile area, the municipality
shall have in place a plan for that area which describes the proposed location,
character, and extent of streets, subways, bridges, waterways, waterfronts, park-
ways, playgrounds, squares, parks, aviation fields, other public ways, grounds,
open spaces, public utilities, and terminals for water, light, sanitation, and
transportation. Power to be provided by the municipality and the proposed land
uses for the area shall be addressed. Such plan shall be updated at least once
annually.
- 5 -
3. Annexation Impact Report (CRS Title 31 -12 -108.5
The municipality shall prepare an impact report concerning any proposed annexation
at least twenty five days before the date of the hearing. Such report shall not
be required for annexations of ten acres or fewer in total area or when the
municipality and the Board of County Commissioners governing the area proposed to
be annexed agree that the report may be waived. Such report shall include as a
minimum a map or maps of the municipality and adjacent territory to show the
following information:
a. the present and proposed boundaries of the municipality in the vicinity of the
proposed annexation;
b. the present streets, major trunk water mains, sewer interceptors and outfalls,
other utility lines and ditches, and the proposed extension of such streets
and utility lines in the vicinity of the proposed annexation;
C. the existing and proposed land use pattern 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 Southeast Quadrant Annexation Master
Plan presently existing and as same may hereafter be amended.
The Petitioner shall provide a PMP to City representatives for review. Adequate
time for discussion, debate, and revision should be allowed. The PMP shall
consist of the following:
- 7 -
1. Development Plan
The Development Plan shall be prepared by the Petitioner in consultation with the
City's Subdivision Review Committee and Department of Planning and Development.

1971 Code of Ordinances of the City of Pueblo and as same may be subsequently
amended. A phasing plan outlining the anticipated order of development projects
for the Property shall be included in the Development Plan.
2. Drainage Plan
The Drainage Plan submitted by the Petitioner shall be in accordance with the
Pueblo Storm Drainage Criteria Manual then in effect. This Plan must be certified
by a licensed Professional Engineer competent in the field of surface water
drainage engineering and registered in the State of Colorado.

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

stem by the proposed development shall also be
proposed development shall be mitigated by the
improvements financed by the Petitioner. The
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.
- 8 -

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

2. Section 208 Water Quality Program, Pueblo, Colorado
Water Quality Management Planning is required under Section 208 of the Federal
Clean Water Act, Public Law 92 -800. The purpose of this Act is to preserve and
enhance the Nation's water systems. The Pueblo 208 Water Quality Program was
first implemented in 1977 with subsequent updates in 1981, 1984, and 1987 by the
Pueblo Area Council of Governments (PACOG). The Pueblo Water Quality Management
Plan is now comprised of six (6) volumes:
Volume I: 208 Stream Segment Analysis, June, 1977;
Volume II: 208 Point Source, Non -Point Source, Institution /Management
Subplans, June, 1977;
Volume III: 208 Final Plan and Implementation Schedule, July, 1977;
Volume IV: 208 Plan Update, 1981
Volume V: 208 Plan Update, 1984; and
Volume VI: 208 Plan Update, 1987.
These plans 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 Geolo2v 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.
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 develop-
ment. 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.
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.
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
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. Pueblo Airport Industrial Park Wastewater Treatment Plant Preliminary
Engineering Study
CII2M Hill Consultants prepared the Pueblo Airport Industrial Park Wastewater
Treatment Plant and Preliminary Engineering Study for the City of Pueblo in March,
1988. A supplement to the study was prepared in February, 1980. The original
study stated that the existing Airport wastewater treatment facility would not be
capable of processing wastewater flow and loading in the event of significant —
industrial growth within the Airport Industrial Park. Several industrial
development scenarios were used to calculate five flow and loading projections.
The study then examined five wastewater management alternatives in respect to the
flow and loading projections, cost effectiveness, and other non - monetary
criteria. 012M Hill recommended that the City pump wastewater back to the main
treatment plant. —
In the original study, CII2M Hill included another possible alternative. This
alternative would require that additional wastewater be pumped back to the main
City plant and that current flows be treated at the Airport treatment plant. It
was determined in the supplemental study that continued treatment of current flows
at the Airport treatment plant is not a feasible alternative. CH2M Hill replaced
this alternative with a pumping system - -three pump stations placed strategically
along the route of the pipeline. They have identified this alternative to be the
most economical. In addition, it allows for better access into the system.
5. Airport Noise Compatibility Program
Federal Aviation Regulation (FAR) Part 150 implements portions of Title I of the
Aviation Safety and Noise Abatement Act of 1979. It establishes a single system
for the measurement of airport (and background) noise, a single system for
determining the exposure of individuals to airport noise, and a standardized
airport noise compatibility planning program. The planning program includes:
(1) a provision for the development and submission to the FAA of noise exposure
maps and noise compatibility programs for airport operations;
(2) standard noise units, methods, and analytical techniques for use in airport
noise assessments;
(3) identification of land uses which are normally considered compatible (or
non- compatible) with various levels of noise around airports; and
(4) procedures and criteria for FAA approval or disapproval of noise
compatibility programs by the administrator.
The program includes consideration of alternative noise control that might be
employed as well as appropriate land use planning strategies. The goal of the
overall program is for the airport proprietor (in consultation with State /local
planners, local aviation groups, and interested citizens) to develop a balance and —
cost- effective program to minimize and /or mitigate the airport's noise impact on
local communities. This study is currently being prepared.

6. Pueblo Memorial Airport Master Plan
This Airport Master Plan was prepared to provide an objective analysis of the 1975
facilities and capabilities of Pueblo Memorial Airport. It presents a detailed,
yet flexible, plan for the future needs of the Airport. Based upon the available
data, this plan was designed to furnish reasonable recommendations for the
aviation needs of 1975 and thereafter for the Pueblo area.
Recommendations and alternatives for meeting aviation demands were presented.
These provided for short -range (5- year), intermediate range (10- year), and long
range (20 -year) development.
It should be understood that this document, although detailed, is for use as a
general guideline for the continued development of the Pueblo Memorial Airport and
AIP areas. The development recommendations set forth in this analysis will
provide guidance for the long -range airport needs of the Pueblo area. The Airport
Master Plan is currently being updated.
C. TRANSPORTATION
1. Year 2000 Transportation Plan Re port
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.
- 19 -
This Plan and the Year 2010 Plan, anticipated to be completed in 1989, are
statements of present policy toward future needs. The Year 2010 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 Traffi 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
developable 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 Southeast Quadrant has been included in the
"Transportation Network" section of this report.

IV. THE SOUTHEAST QUADRANT THREE -MILE ANNEXATION PLAN
PREFACE
The population of the City of Pueblo is predicted to reach 110,000 persons by the
Year 2000, resulting in an increase of 10,000 persons. It is anticipated that
this growth will be fueled predominantly by the expanding employment opportunities
at the Pueblo Airport Industrial Park. Recent annexation and development
proposals indicate that a substantial portion of the airport and industrial park's
support industries, such as restaurants, hotels, limited single and multifamily
_ housing, service stations, and other commercial and office growth, will occur in
the Southeast Quadrant. Proper planning of this development in this quadrant will
ensure compatibility with existing land uses and with airport activities.
- 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
Southeast 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[l][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 Southeast 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 Southeast Quadrant. The Three -Mile
Plan shall be used to provide guidance in the review of development proposals and
in the negotiation of annexation agreements.
The boundaries of the study area are U. S. Highway 50 -B to the north, the
St. Charles River on the east, the Comanche Power Plant to the south, and
Interstate 25 to the west. The eastern boundary of the Southeast Quadrant has
been extended further than the required three miles in order to align with the
easterly boundary of the Northeast Quadrant Annexation Master Plan. The study
area has been partitioned into two areas:
- 21 -
(1) a proposed urban extension area representing that portion of the Southeast
Quadrant in which municipal services could logically be extended (See Map
III); and
(2) the remainder of the study area which will not be master planned.
The primary components of this Plan include the identification within the proposed
urban extension area of existing and proposed major transportation corridors, the
anticipated land use around these corridors, and specific development guidelines.
Secondary components include the anticipated location of major public facilities
and district and urban parks.
A. EXISTING AND PROPOSED MAJOR TRANSPORTATION CORRIDORS
1. East /West
The major east /west transportation corridor in the Southeast Quadrant's proposed
urban extension area is U. S. Highway 50 -B. Due to the Highway's location and
volume capacity, and due to the natural barrier of the Arkansas River on the
south, no additional major east /west corridors will be necessary within the
proposed urban extension area. Increased development within this area will make
construction of a highway frontage road viable. In addition to serving future
development, this frontage road would provide an increased element of safety by
controlling access onto U. S. Highway 50 -B.
2. North /South
Baxter Road is the only principal north /south arterial in the proposed urban
extension area. The following roadways are classified as minor north /south
arterials: Joplin Avenue (Colorado Highway 227), Baxter Road (Colorado Highway
233), and 36th Lane (Colorado Highway 231).
It is anticipated that along with growth in this Southeast area, the demand for
additional north /south transportation routes will increase. Proposed major north/
south transportation corridors will include the southern extension of 27th Lane
and the southern extension of Paul Harvey Boulevard, as identified in the
Year 2010 Transportation Plan Report. The construction of a bridge over the
Arkansas River will be necessary in order to extend 27th Lane. Major grade
separated intersections will be necessary at the points where U. S. Highway 50 -B
crosses 27th Lane and 36th Lane. The exact alignment for new road construction
has not yet been determined. In some cases, it may be necessary to relocate
roadways in order to accommodate anticipated volume in a manner that is both safe
and compatible with existing land uses.
- 22 -
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 27th Lane. 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
sidewalk construction. Due to the fact that
corridors exceeds the City's current standard,
adoption of an impact fee, or alternate system,
these corridors.
B. THE PROPOSED URBAN EXTENSION AREA
the entire cost of roadway and
the envisioned standard of these
the City may choose to study the —
to help fund the construction of
All residential, commercial, and industrial development within the Southeast
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.
Zoning and land use policies impacted by airport noise zones shall be compatible
with airport operations. It is recommended that prior to the completion of the
FAA Part 150 Airport Noise Study and the Airport Master Plan Update, development
within airport noise zones be in accord with the standards found in Table I. —
Petitioners seeking to annex property located within the Southeast Quadrant will
be required to grant a Standard Avigation Easement to the City. All rezoning
requests within the Urban Service Area will be requested to grant a Standard
Avigation Easement. Said easement is attached as Appendix 1.
In an effort to better identify anticipated land uses, the proposed urban —
extension area has been divided into three distinct regions (See Map IV).

150 are not intended to substitute federally- determined land uses for those determined to be appropriate by local
authorities in response to locally- determined needs and values in achieving noise compatible land uses.
Y (Yes) -- Land use and related structures compatible without restrictions.
N (No) -- Land Use and related structures are not compatible and should be prohibited.
NLR -- Noise Level Reduction (outdoor to indoor) to be achieved through incorporation of noise attenuation Into the
design and construction of the structure.
20, 25. or 30 -- Land use and related structure generally compatible, measures to achieve NLR or 25, 30, or 35 must
be incorporated into design and construction of structure.
1- Where the community determines that residential uses must be allowed, measures to achieve outdoor to indoor
Noise Level Reduction (NLR) of at least 25 dB and 30 d0 should be incorporated Into building codes and be con-
sidered in individual approvals. Normal construction can be expected to provide a NLR of 20 dB, thus, the
reduction requirements are often stated as 5, 10, or 15 d0 over standard construction and normally assume
_ mechanical ventilation and closed windows year round. However, the use of NLR criteria will not eliminate out-
door noise problems.
2- Measures to achieve NLR of 25 must be incorporated into the design and construction of portions of these build-
ings where the public is received, office areas, noise - sensitive areas or where the normal noise level is low.
3- Measures to achieve NLR of 30 must be Incorporated into the design and construction of portions of these build-
ings where the public is received, office areas, noise - sensitive areas or where the normal noise level Is low.
4- Measures to achieve NLR of 35 must be Incorporated into the design and construction of portions of these build-
- ings where the public is received, office areas, noise - sensitive areas or where the normal noise level is low,
5- Land use compatible provided special sound reinforcement systems are installed.
6- Residential buildings require an NLR of 25.
7- Residential buildings require an NLR of 30.
8- Residential buildings not permitted.

1. Upper Region (See Map V
The upper region is bound on the north by U. S. Highway 50 -B and on the south by
the vacated Booth Orchard Ditch. Although it lies east of the ditch, for planning
purposes, the Meadowbrook Mobile Home Park has been included in this region.
Please note that in those areas where the ditch and the Special Flood Hazard Area
— (100 -year floodplain) of the Arkansas River, Fountain Creek, and specific tribu-
taries intersect, the vacated Booth Orchard Ditch is used as the dividing line.
The upper region is not ideal for extensive residential development. The closure
of Baxter Elementary School due to insufficient enrollment indicates a declining
residential intensity in the area. It is anticipated, however, that predicted
residential development within the Northeast Quadrant will require the reopening
of the school in the future.
The lack of new housing stock in the upper region may be attributed to its close
— proximity to U. S. Highway 50, the Airport Industrial Park, the Pueblo Memorial
Airport, and proximity to airport noise zones. Currently, only a small area of
the upper region is impacted by airport noise; however, these noise zones may
change or expand as a result of airport growth. The planned instrumentation of
— the north /south runway with resulting increased use will dramatically impact the
noise contours immediately south of the airport. A portion of the Baxter
community, currently a low to medium density residential (conventional and
manufactured) neighborhood (R -1, R -2, R -8), may be within the noise zone influence
area of the north /south runway. Residential development is not desirable within
this influence area. Compatible development may be found in Table I.
Mobile home parks and subdivisions (R -7, R -8) shall be permitted where currently
in existence. Expansion of the parks and subdivisions should be closely monitored
and allowed only if compatible to airport operations and 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.
It is anticipated that the market will dictate concentrations of commercial/
industrial land uses at the intersections of major transportation corridors.
— Clustering of subregional and highway commercial uses (B -2, B -3) should be
promoted at the intersections of U. S. Highway 50 -B with 27th Lane,
Paul Harvey Boulevard, Baxter Road, and 36th Lane. Commercial and office
development (B -3, 0 -1) mixed with light industrial uses (I -2) should be permitted
— along the U. S. Highway 50 -B corridor. Simultaneous development of a highway
frontage road should be required.
— The upper region is in a state of transition. It is expected that it will develop
as a mixed -use area, including light industrial, commercial, office uses, and
multifamily residential. It is also expected that many of these developments will
— support activities at the Airport and Airport Industrial Park. Heavy industrial
uses are not anticipated and should not be encouraged. Due to the existing mixed
uses in the upper region, development should be reviewed on a case -by -case basis.
The density of land development will partially be determined by the availability
— of water and sanitary services in the area.

2. Middle Region (See Map V)
The middle region is bound on the north by the vacated Booth Orchard Ditch and on
the south by the northern boundary of the 100 -year floodplain. It also includes
the area east of the Meadowbrook Mobile Home Park (34th Lane) that is south of
U. S. Highway SO -B and north of the 100 -year floodplain.
With the exception of one industrial area, the middle region consists of dryland
farming and scattered single- family residences. This type of rural - residential
development (one to five acres) should be encouraged in this region. The vacated
Booth Orchard Ditch should be viewed as a transition line between the upper and
middle regions, and medium to high density residential development should only be
considered within the middle region as sanitary sewer services become available.
Additional industrial and commercial development should be discouraged since
commercial nodes within the upper region will sufficiently serve the low density
needs of the middle region.
As build -out of the upper region occurs and land use patterns and growth trends
emerge, modification of the middle region's proposed land use will be necessary.
3. Lower Region (See Map V)
The lower region is bound on the north by the northern boundary of the 100 -year
floodplain and on the south by the Arkansas River. It is entirely within a
100 -year floodplain; and unless it can be demonstrated through issuance of a Flood
Hazard Development Permit that said development will not be affected by a flood of
100 -year magnitude, most types of development within this region should be
discouraged.
— Although most types of development in this region should be discouraged, large
deposits of sand and gravel within these floodplains ensure that high levels of
extraction activity will continue in the lower region for many years. The
majority of the lower region has already been permitted for the extraction of
natural resources. These proposed extraction sites contain thousands of acres;
and due to bonding limitations and expense, reclamation plans have been filed only
on those acres currently being mined. Recent water augmentation law may impact
— extraction plans which would result in exposed groundwater, thus impacting future
reclamation plans of those areas that contain a high groundwater table. It is
anticipated, and should be encouraged, that due to floodplain development
restrictions the majority of this region will be reclaimed for "open space/
wildlife" use. Reclamation of this property as "open space /wildlife" use will
enhance and further the trail system along the Arkansas River.
- 29 -
C. DEVELOPMENT GUIDELINES
The following guidelines should be considered at the time of development for
properties within this quadrant.
1. Residential
(a) Transitional high- density residential (R -4, R -5, R -6) or office (0 -1)
development between single- family residential (R -1, R -2) and commercial
(B -1, B -2, B -3) land uses should occur.
(b) No single- family residential units (R -1, R -2, R -3, R -4) shall be
permitted private access onto major transportation corridors.
(c) The Colorado State Highway Access Code shall be followed in permitting a
common access onto major transportation corridors for multiple
residential units (R -5, R -6, R -7).
(d) All residential units adjacent to principal arterials and expressways
shall be required to provide properly engineered noise buffers (e.g.,
berms, fencing, landscaping, or increased setback) between the residence
and the roadway. The buffers must meet a design standard, to be
established by the City of Pueblo.
(e) Every 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 (B -2. B -3) at the
intersections of U. S. Highway 50 -B and 27th Lane, Paul Harvey Boulevard
extended, Baxter Road, and 36th Lane should be permitted if compatible
with existing land uses.
(b) Commercial and office development (B -3, 0 -1) mixed with light industrial
(I -2) uses should be permitted along the U. S. Highway 50 -B corridor.
(c) 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.
- 30 -
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. However, extensive annexation and development
in this Quadrant, coupled with growth at the Airport Industrial Park, will require
that an an additional patrol route be instituted. This patrol would adequately
serve the Southeast Quadrant proposed urban extension area at build -out.
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 or expansion of staff and equipment at the
Airport Fire Station No. 10 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.
E. PARKS, OPEN SPACE, AND TRAILS
1. Parks
Although intense residential development is not proposed, the existing Baxter
park /playground is not sufficient to meet the current or future needs of the urban
extension area. The existing park /playground, adjacent to Baxter Elementary
School, is owned by School District No. 70 and maintained by the County Parks
Department. Establishment of new parks and facilities in the proposed urban
extension area will serve to correct existing deficiencies in the area.
Increased future recreational demand should be anticipated from the middle region,
which is proposed for rural residential development. If Baxter Elementary School
remains closed, adoption of the school as a multi -use recreation center should be
investigated.
The remainder of the Southeast Quadrant is severely deficient in adequate park
facilities.

the provision of free water set forth by the City of Pueblo
(Board of Water Works Rules and Regulations, October 18,
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 a park 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 proposed intersection of 27th Lane
extended and the Arkansas River (See Map V). This park should be a minimum of 25
acres and provide specialized facilities such as docking areas for boats and rafts
and regulation -size playing fields. Large grass and tree areas and specially
landscaped open areas should be developed. Recreational programming should be
provided for all ages. This location would provide access to the recreational
trails system and Arkansas River natural areas and would be ideal for river
interpretation programs. The park would be accessible and available to a large
population once 27th Lane is extended south across the river and north to the
Airport area.
In addition, there are plans to centrally locate a district park (specific site
not yet determined) to serve the residents of the St. Charles Mesa.
c. Urban Park
Every attempt should be made to acquire land at the confluence of the Fountain
Creek and Arkansas River for development of an urban park. This park should serve
the entire urban community and should consist of a minimum of 200 acres. A
conceptual plan developed by the City Department of Planning and Development
combines the natural river areas, Runyon Field, and adjacent vacant land into an
urban park in excess of 300 acres (See Map V). This site shall be open for
multiple, recreational uses including but not limited to ballfields, tennis
courts, a swimming pool, soccer fields, picnic areas, and playfields. Limited
water sports and recreational trail access would be provided. Included in the
conceptual plan is an open -air amphitheater. Such a theater would be near to
Pueblo's downtown, thereby complementing any future convention /hotel facility.
- 32 -
2. Open Space
The Arkansas River floodplain is considered to be a critical riparian habitat by
the Colorado Division of Wildlife. Every attempt should be made to maintain the
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.
3. Trails
To ensure continuity of the bicycle and pedestrian trail system, all developers
should be responsible for the dedication of ROW 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 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, park and school locations, and
watercourses, and at the Pueblo Memorial Airport and central commercial centers
(See Map VI).
All trails shall be constructed pursuant to standards set forth by the Pueblo
Master Trails Plan, then in effect.

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 Southeast 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 hazard
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 Southeast 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 Southeast 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 Southeast Quadrant consists of Pierre shales (Kpl) and
Niobrara formations (Kn) (See Map VII). Members of the Pierre shales include
Apache Creek Sandstone (Kpa), Sharon Springs (Kps), and Transition (Kpt).
Members of the Niobrara (Kn) formations include Upper Chalk (Ksuc) and Upper
Chalky Shale (Ksus). Their corresponding geologic properties can be found in
Table II -A.
Beds of Bentonite can be found in these 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.
Most bedrock in the region contains sulfate compounds. When dissolved, these
compounds react with concrete and cause deterioration. Deterioration can be
avoided in most new construction by use of sulfate - resistant cement.

2. Surficial Geolo
Much of the bedrock in the Southeast 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. These surficial deposits overlie the
sedimentary bedrock except where faulting, folding, or erosion have exposed
bedrock sections. Surficial deposits in the Southeast Quadrant include Broadway —
Alluvium (Qb), Colluvium (Qc), Eolian Sand (Qes), Louviers Alluvium (Qlla),
Post -Piney Creek Alluvium (Qpp), Rocky Flats Alluvium (Qrfa), and Slocum Alluvium
(Qsa). The geologic properties of these deposits are located in Table II -B. The
USGS has detailed maps locating surficial deposits in the Southeast 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 soil
composition in defined proportions. Map VIII illustrates soil associations in
the Southeast Quadrant. These soils have been classified into two groups: soils
on plains and soils on terraces and floodplains.
The following information provided in this Master Plan refers to general soil
composition. More specific information is available and should be referenced for —
detailed Planning and Development decisions.
As shown on Map VIII, the soils in the Southeast Quadrant and their
characteristics are:
(1) Soils on Plains
Limon - Razor -- Midway Association: Deep to shallow, well drained silty clay loams,
clay loams, and clays that formed in materials weathered from shale. Erosion is —
moderate.
Manvel Association -- Adena -- Manzanola Association: Deep, well drained loams, clay
loams, sandy loams, and silty clay loams that formed in loams and in loamy clayey
alluvium. Erosion is moderate.
(2) Soils on Terraces and Floodplains
Cascajo- Schamiber Association: Deep, well drained to excessively drained
gravelly sandy loams that formed in coarse textured alluvium on high terraces and
terrace edges. Erosion is slight.
Rocky Ford Association: Deep, well drained silty clay loams that formed in silty
alluvium on terraces.
Las Animas -- Glenburg Apishapa Association: Deep, somewhat poorly drained to well
drained fine sandy loams and silty clays that formed in alluvium on floodplains.
Erosion is slight.

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 existing surface or geologic structures found in the area.
Processes are the natural and chemical erosional elements which modify the
structure. Stage indicates the length of time in which the erosion takes place.
The physical characteristics of the Southeast Quadrant are illustrated on
Map IX. They include a mesa, the floodplain of the Arkansas River and
Fountain Creek, and a terrace area.
— 4. Drainage
There are four north -bank tributary sub - drainage basins and three south -bank
tributary sub - drainage basins in the study area. These basins empty into the
Arkansas River drainage basin (See Map X).
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,
St. Charles River, Salt Creek, two unnamed north bank tributaries, and a small
portion of low land are classified as 100 -year floodplains (See Map X).
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. However, below this confluence high runoff from the Fountain Creek
and the other drainages could cause flooding on the Arkansas's lower portion
contained within the study area.
5. 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.

6. Flora and Fauna
Plant and animal associations are groups of species co- existing in a
complementary fashion. Groups of associations are called communities. A biotic
zone consists of an association of communities. These zones are defined by soil,
moisture, climate, and the biotic history of the area. These conditions
determine the nature and distribution of plant and animal habitat.
The Southeast 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 Southeast Quadrant include:
a. Grasslands of the Plains - -Blue grama is the dominant grass with smaller
traces of western wheat and galleta present.
b. Woodlands of the River Bottoms -- Vegetation includes cottonwoods, willows,
rabbitbrush, forbes, cattails, wild rye, alkali sacaton, inland salt grass,
muhly, and sand dropseed.
c. Woodlands of the Foothills and Plains -- Vegetation includes pinon pine, one
seed and Rocky Mountain junipers, mountain mahogany, skunkbrush, sumac,
gambel oak, Indian rice grass, big and little blue stem, blue grama, sideoats
grama, and western wheatgrass.
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 Southeast Quadrant are Riparian, Urban, Woodland, and
Plains Breaks and Grasslands. Habitats are valued in terms of food sources,
vegetative cover, water availability, shelter, and breeding grounds. Different
animal species relate to different habitats. According to the Colorado Division
of Wildlife, the Arkansas River floodplain is considered to be critical Riparian
habitat. Critical habitat is that which offers rare or limited environmental
conditions and includes those areas which support rare and endangered plant or
animal species. Animal inhabitants of the area include coyotes, antelope, small _
mammals, small birds, quail, larger raptors, crows, and a variety of water fowl.
The Arkansas River is included in the wintering ground of endangered species such
as the American Bald Eagle, the Golden Eagle, and the Night Heron. It is
imperative that the river environment is preserved and that endangered species
are protected from further urban enchroachment. Zoning for parks and
recreational open space is encouraged in the floodplain to help facilitate this
preservation.
- 44 -
7. Water Quality
_ Water quality standards and classifications have been adopted by the State to
ensure the quality and acceptability of Colorado's waters for public use.
The 1984 208 Water Quality Program Update states that the Pueblo region's water-
- ways are improving in quality. However, segments of the Arkansas River and the
Fountain Creek are still impaired. Proper water treatment by the Board of Water
Works and outlying water districts provide safe water to Pueblo and the Southeast
Quadrant. Private wells, however, do not guarantee safe - drinking water.
Segment C of the Arkansas River refers to the river stretching from its
confluence with the Fountain Creek to the Kansas border. This segment is
classified as a Class II Recreational, Warm Water Aquatic Life - -Class II,
Agricultural and Domestic Water Supply. The Class II Recreation classification
indicates that these surface waters are suitable or intended to become suitable
for recreational uses on or about the water and does not include primary contact
with the water. The Lower Arkansas is considered, by the State Water Quality
Control Division, as impaired with fecal coliforms and metal traces.
Agricultural uses, wastewater disposal, and discharge from industry and upstream
mining are considered possible causes.
_ The Lower Fountain Creek, north bank tributary to the Arkansas, is classified as
a Class II Recreation -- Agricultural and Domestic Water Supply. The State Water
Quality Control Division has declared the Lower Fountain Creek impaired with
fecal coliform and non - ionized ammonia. This portion of the creek has been
impacted by upstream urban areas and agriculture and most probably impacts the
quality of the Lower Arkansas River.
Groundwater in the St. Charles Mesa area is a tributary to the Arkansas River.
Tests indicate elevated levels of nitrates. Nonpoint pollution load is caused by
septic tanks, livestock, and fertilizers.
The 1984 208 Update recommends continuing water quality monitoring, watershed
study, and planning. The document encourages a unified effort by State and local
governments and agricultural representatives to establish soil and water
conservation plans.
8. Air Quality
Air quality in the Southeast 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.
Air quality is determined by monitoring Particulate Matter by a process referred
to as PM -10, or Particulate Matter ten microns or less. PM -10 was preceded by
TSP (Total Suspended Particulate). These tests monitor particles suspended in
the air. 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.
- 45 -
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, and large arroyos exist can place constraints on
development.
Prior to any new development, an environmental analysis should indicate areas of
environmental sensitivity. Mitigating measures should then be utilized in
planning and construction.
The severity and location of various environmental hazards and of mineral
resource areas within Pueblo County were computer- mapped via a program called
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 - -High for Southeast Quadrant; (2) Wildfire
Hazards - -Low for Southeast Quadrant; (3) Geologic Hazards: (a) Unstable slopes;
expansive soils and rocks - -Low to Moderate for Southeast Quadrant; (b) Mud
Flow /Debris Fans; Ground Subsidence -- Moderate to High for Southeast Quadrant; (c)
Landslides; Avalanches; Radioactivity - -No hazards in Southeast Quadrant; and (d)
Seismic Effects - -Low to moderate in Southeast Quadrant; (e) Erosion -- Moderate in
Southeast Quadrant; (4) Mineral Resource Areas - -High Potential for sand and
gravel excavation in Southeast Quadrant; and (5) Environmental Hazards Composite.
The following text describes potential hazards in the Southeast Quadrant:
1. Floodplain Hazards
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 Federal Insurance Administration has delineated areas of special flood
hazards applicable to the City of Pueblo. These are shown on Map X.
- 46 -
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.
It is the goal of zoning and development procedures to protect floodplains in
order to freely discharge a base flood without increasing the water surface
elevation more than one foot. 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.
Z. Drvwash Channels
A drywash channel refers to a small watershed with a very high percentage of
runoff after a torrential rainfall. These channels are not classified as
100 -year floodplains yet they may be hazardous if not properly regarded in the
planning process. Water channels change over time as a result of both natural
_ and man -made conditions. Land disturbances, such as construction, could act as
flow obstructions, possibly increasing flow depths, velocity, and changing
channel course. Drywash channels are located on Map XI.
Prior to development, a master drainage plan must be prepared which would address
natural flows, additional hydrologic flow generated by new developments, and
mitigating measures necessary to insure adequate drainage. Improvements might
include holding ponds, diversion channels, drainage pipes, gutters, and channel
boxes. Hydrologically, the results are similar but the cost and amount of land
required for such measures varies.
3. 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 Southeast 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.
4. 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-- mudflows /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).
- 47 -
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.
The slopes in the Southeast Quadrant are not considered "severely" unstable or
hazardous by the IMGRID analysis. Specific construction and design techniques
can be utilized, thereby mitigating hazards such slopes pose.
b. Mud Flows /Debris Fans
A mud flow (also called earth flow or debris flows) 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. Since the Arkansas River floodplain encompasses a sizeable
portion of the study area, mud flow /debris fan hazards are considered extensive
(See Map XI).
c. 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 Southeast Quadrant, proposed urban extension area, has a subsidence hazard as
illustrated on Map XI. Techniques for mitigating problems caused by subsidence
on structures do exist and should be reviewed prior to structural design.
d. Expansive Soils and Rocks
Expansive soils and rocks contain clay which, due to their molecular structure,
expand to a significant degree upon wetting and shrink upon drying. Map XI
illustrates those areas found to have moderate to high expansive properties. It
should be noted that the majority of these hazardous areas are in the proposed
urban extension area.
Certain types of structures can be severely impaired by such soil movements.
Professional soil engineers or geologists should be involved in project design.
- 49 -
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. Areas bordering
the Arkansas and St. Charles River, according to the IMGRID analysis, are
considered low to moderate seismic hazardous areas. The remainder of the study
area is classified as a low hazardous area.
f. Erosion
Erosion is the end - result of a culmination of factors such as vegetative and
man -made cover types, gradient, the chemistry make -up of soil, weathering,
overgrazing, and other man - caused disturbances.
The erosion problem in the study area is low to moderate with one given acre
losing five to 100 tons of soil per year. The most detrimental soil losses occur
on the sloping areas of the Arkansas and St. Charles Rivers floodplains and
terraces.

The Manual is expected to be adopted in 1989.
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 Southeast
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.
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."
MIM
Mineral deposits within Pueblo County have been identified by the Colorado
Geological and U. S. Geological Survey. Deposits of sand and gravel are abundant
near the St. Charles and Arkansas Rivers.
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 of sand and gravel are issued by the County Planning
Commission.
Active and inactive extraction pits and processing operations within the
Southeast Quadrant are located on Map XII, and the corresponding status and types
are listed below.

The Southeast Quadrant is relatively stable. A composite of various environmental
factors is graphically depicted of those areas determined to be "environmentally
sensitive (See Map XI)." Individually, certain hazardous conditions such as
expansive soils and erosion can be mitigated through sound structural engineering
and landscaping design. However, some areas with multiple hazards might well
_ dictate architectural engineering and design. Without more indepth study, it
would be difficult to estimate the degree to which these lands are sensitive.
Decisions to develop environmentally sensitive lands should be based upon an
environmental assessment study. This assessment should address drainage, geologic
hazards, and erosion.
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.

VI. INFRASTRUCTURE
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 commercial, residential, or industrial, will impact the
existing infrastructure and will result likewise in the expansion of municipal
services.
This section will discuss the existing transportation routes, water and waste-
- water systems, electrical and gas services, telephone services, and cable
television systems. An analysis will address the ability of these services to
expand and support new development.
A. TRANSPORTATION NETWORK
The major transportation routes serving the Southeast Quadrant are (See Map XIII):
1. U. S. Highway 50 -B, an expressway and national east /west route serving as the
primary entrance to the Pueblo Memorial Airport.
2. U. S. Highway 50 -C (Santa Fe Drive), a principal arterial and east /west access
to the St. Charles Mesa community.
3. South Road, an east /west minor arterial serving the southern portion of the
St. Charles Mesa.
4. Joplin Avenue (State Highway 227), a north /south minor arterial.
5. Baxter Road (State Highway 233), a north /south principal arterial serving the
_ Baxter community and providing a link between U. S. Highway 50 -B and U. S.
Highway 50 -C.
6. Lane 36 (State Highway 231), a north /south minor arterial.
The segment of the Arkansas River, contained within the study area, is bridged by
Santa Fe Avenue, Joplin Avenue (State Highway 227), Baxter Road (State Highway
233), and by 36th Lane (State Highway 231). The St. Charles River is bridged at
U. S. Highway 50 -C, South Road, and 27th Lane.
Transportation planning, in the City of Pueblo, is accomplished with the aid of
three transportation studies - -the Analysis District Evaluation to the Year 2010,
the Year 2000 Transportation Plan and its successor the Year 2010 Transportation
Plan (to be adopted in 1989). The Year 2000 and Year 2010 Transportation Plans
utilize computer modeling 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
for the Year 2010. This plan provides population, dwelling units, and employment
projections for Pueblo County's 139 traffic zones. The Southeast Quadrant is
comprised of nine zones, with the majority of the proposed urban extension area
contained within two zones (87 and 133). The Evaluation predicts slow growth for
all nine zones through the Year 2010. Table III lists the Evaluation's
projections and Map XIV illustrates corresponding traffic zones.
The Three -Mile Annexation Plan, Section IV of this report, proposes two roadway
extensions. The first proposal is the extension of 27th Lane south from U. S.
Highway 50 -B, bridging the Arkansas River and joining South 27th Lane. The second
proposal is the southern extension of Paul Harvey Boulevard (See Map IV).

B. WATER SERVICE
Pueblo County's water supply flows from mountain snowmelt. The mountain water
travels via streams, creeks, groundwater flows, and man -made water systems to the
major Eastern Colorado drainage basin of the Arkansas River.
Several suppliers provide water to the Southeast Quadrant Study Area. They
include the St. Charles Mesa Water District, O'Neal Water Supply, and the Pueblo
Board of Water Works.
The Pueblo Board of Water Works is the primary purveyor of water for the City of
Pueblo. The Board does not have a franchise agreement with the City; therefore,
upon annexation, private water suppliers may continue service to their customers.
Officials at the Board have stated that the water supply companies in the
St. Charles Mesa adequately serve their customers with quality water. The Board
does not consider it probable that Board water will be requested in this area.
The Board, however, does provide service to several parcels in the proposed urban
extension area and can adequately serve a build -out population therein.
— The Pueblo Board of Water Works owns parts of the Arkansas River flow referred to
as "direct flow water rights." By State law, this water must be used at the time
of diversion and may not be stored in its raw state. The Board also owns rights
to water originating on the Western Slope. This water may be stored. The Board
has water rights and storage capacity to support a population of 350,000 persons.
Water diverted from the Arkansas River enters the Whitlock Treatment Plant. This
plant became operational in 1977. The treatment process employed by the Board of
Water Works includes flocculation, sedimentation, and a filtration process.
Testing on a continual basis ensures Pueblo of high quality water through rigid
quality control methods. The plant has the capability of serving a population of
158,000. There is no further opportunity for expansion at the Whitlock Plant.
The Board of Water Works does own a plant site downstream from the Pueblo Dam. If
— facility expansion was necessary, a "peaking plant" could be constructed on this
site. Such a facility would supplement the existing plant during peak summer
months and would likely be shut down during winter months.
Treated water from the Whitlock Treatment Plant is transferred to the distribution
system. This system is divided into pressure zones in order to maintain water
pressures within practical limits. The Southeast proposed urban extension area
lies within the 1000 Zone (See Map XV). This represents ground elevation (City of
Pueblo datam) of 4,650 to 4,750 feet above Sea Level. The 1000 Zone receives its
water from the Watts Reservoir and pumping station north of 32nd Street and the
J. 0. Jones tanks and pumping system on Widener Drive. Currently, distribution in
the proposed urban extension area consists of two water mains, a 20 -inch and a
16 -inch line which lie in the U. S. Highway 50 -B corridor. These lines are cross
tied for reliability and serve the Pueblo Memorial Airport, the Airport Industrial
Park, and several properties south of U. S. Highway 50 -B.
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" identified on Map XVI.

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 negotiated, the applicant has 120 days in which to act while
being guaranteed the negotiated fees. After this time, fees will be allowed to
fluctuate. The plant water investment fee is charged to customers seeking service
through new, additional, or increased size of meter, or number of units effective
January 1, 1989, as shown on the following Table IV.
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 V. If an applicant requests that the
Board install a main extension inside City limits, 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 an additional charge.
It should be noted that the workload of the Board does not allow for any early —
scheduling of water main installation. There is a one -year completion deadline
and no extension of time will be granted. Furthermore, the established costs per
linear foot do not refer to the applicant's actual cost to install the water —
main. In certain areas, such actual costs may exceed the costs outlined. Any
additional costs are the responsibility of the applicant. All work is to be
thoroughly inspected by the Board of Water Works.
A small section of the proposed urban extension area is supplied by the O'Neal
Water Supply Service (See Map XV). This company serves approximately 400 people
in a one -mile radius. Raw water is obtained from a well and runs through a —
chlorination treatment process. The water quality is in compliance with Colorado
Primary Drinking Water Standards.
Some residents continue to utilize private wells. The groundwater in the
St. Charles Mesa area has high nitrate levels and is not considered a guaranteed
safe water source without proper treatment.
In the semiarid Southeast, water is viewed as a limited resource. Individual
wells are coming under closer scrutiny by the State's regulatory authorities as to
their affect on surface water rights. Subsurface waters in the State are
considered to be tributary to surface water rights, unless through the provisions
of Senate Bill 213 (1973) non - tributary status can be established. If in the
application process a proposed new well is found to be tributary, water —
augmentation may be required. In addition to water augmentation legislation, the
importance of community water systems is further substantiated by the considerable
cost of tapping a non - tributary aquifer to avoid water augmentation. In Pueblo _
County, non - tributary aquifers are generally in excess of 800 feet below surface.
Neither tributary nor non - tributary wells are assured to produce potable water.
Based on these conditions, it can be assumed that most of the future growth in the
Pueblo region will be dependent upon community water supply systems.

C. WASTEWATER
The City of Pueblo Department of Public Works is responsible for the sanitary
sewerage and wastewater treatment operations for the City of Pueblo and the Pueblo
Memorial Airport and Airport Industrial Park.
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.
A smaller treatment facility is located at the east end of the Airport Industrial
Park. This treatment facility is not capable of expansion. The Pueblo City
Council is currently examining alternatives to process wastewater in the area.
The proposed urban extension area of the Southeast Quadrant could be affected by
the Council's decision.
In 1988, CH2M Hill, consulting engineers, released the Pueblo Airport Industrial
Park Wastewater Treatment Plant Preliminary Engineering Study. This report
examines five alternatives for processing the increased wastewater flow and
loading at the Pueblo Memorial Airport. The engineering report recommended
pumping all wastewater back to the City's main plant.
CH2M Hill recently completed a supplemental study. The supplemental study
addressed additional alternatives. One alternate plan which would utilize the
existing AIP wastewater treatment plant for the current load and would pump any
additional flow back to the City plant was determined not to be a feasible
alternative. CH2M Hill replaced this alternative with a pumping system with three
pump stations, placed strategically along the route of the pipeline. They have
identified this alternative to be the most economical. In addition, it allows for
better access into the system.
The City "ultimate" wastewater service line as defined by the 1971 Sellards and
Grigg Report is depicted on Map XVII. This boundary line indicates an area
adjacent to the City which may be served by the existing treatment system and
gravity -flow basins. Wastewater service outside this area may be costly. At this
time, the engineering staff of the City's Public Works Department has not yet
determined the construction needs of the Southeast Quadrant.
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.
- 62 -
If prior to July 1, 1989, the new treatment plant is in full operation, it is _
likely that this amendment will be repealed.
Three sanitation districts provide service to the study area's residences
(See Map XV).
The Blende Sanitation District serves approximately 574 persons (1987). Effluent
from the area is transported to the City wastewater facility. The City, —
therefore, must approve all extension of service and has the right to withdraw
service should the plant's capacity be needed to serve the City's residents.
The Salt Creek Water and Sanitation District has a user population of 650. The
District discharges into the Blende sanitation system.
Also discharging into the Blende system is the St. Charles Sanitation District.
This District's user population numbers 372.
Meadowbrook Mobile Home Park provides its own wastewater treatment with an
activated sludge package plant. This plant produces liquid sludge which is pumped
once a month. Effluent is discharged for treatment at the City of Pueblo's
wastewater treatment plant (See Map XVII).
CF &I Steel Corporation produces wastewater and provides its own treatment through
clarification, settling, filtering biological oxidation, and aeration. Final
treatment occurs in two treatment lagoons. These lagoons discharge into the —
Arkansas River (See Map XVII).
Septic tank pumpers and haulers which pump out and dispose of septic waste 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. They are issued annually —
and complaints on safety and dumping can result in the revocation of a license.
The exact number of septic tanks in the area is not known, although it is believed
to be well over 1,000. The 1984 208 Water Quality Program Update states that in
many areas parcels are too small and soils inappropriate to support individual
septic tanks and leaching systems in compliance with the Colorado Department of
Health and the Pueblo City- County Health Department's regulations. The Update
also states that faulty septic systems are believed to be a cause of groundwater
contamination.
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). Residen-
tial development has the most impact in the system, with high- density units being
the most severe. Typically, commercial and industrial uses are not in full —
operation at peak hours.
- 64 -
In the event of a new development project, a sanitary sewer report will be
completed outlining the proposed development and its probable impact on the
sewerage 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.
D. ELECTRIC POWER
Centel Corporation (Centel Electric -- Colorado) is the electric power company which
serves the study area. The company has a franchise agreement with the City of
Pueblo to be the sole provider of electricity within municipal boundaries.
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 (EPA) requirements. Generation facilities at the
plant consist of two units with a capacity of 8,000 kilowatts each; one unit with
19,000 kilowatt capacity; and five diesel generators, each with a capacity of
2,000 kilowatts. 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
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 electric energy throughout the City of Pueblo through its
transmission and distribution network. The Southeast Quadrant of the City is
served by five distribution substations. These substations are served by 69,000
and 115,000 volt electric transmission lines (See Map XVIII). The transmission
lines are located on utility easements of 120' for parallel lines and 100' for
single lines. Centel officials state that all requests'for electric service in
the study area can be fulfilled with reasonable promptness.
- 65 -
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 system extension costs are estimated on
the basis of the anticipated construction and installation costs, including
material, labor, rights -of -way, trenching, backfill, tree trimming, and any
incidental and overhead expenses. An applicant for permanent service is required
to pay all distribution extension costs in excess of a construction allowance
determined by 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 Pueblo and the
surrounding area including the Southeast Quadrant. 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, intermediate, or
temporary. The proposed service installation is analyzed in order to estimate
costs of labor, materials, and rights -of -way, and any incidental and overhead
expenses. This estimate is the construction payment.
An applicant for permanent service will receive a construction allowance.
Indeterminate and temporary customers do not receive construction allowances.
Distribution lines are installed by the company and paid for by the applicant
(less the construction allowance).
_ Construction payments are refundable in part or in their entirety within a five
year period, commencing with the extension completion date. When a new customer
is added to the line, his or her share of the construction payment is refunded to
those who initially paid for the installation of the distribution line. These
refunds are 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 Colorado Public Utilities
Commission. Policies are subject to periodic change.
- 67 -
F. TELEPHONE
U. S. West Communications provides local telephone service to the City of Pueblo
and to the Southeast Quadrant. The technical service is divided by 27th Lane,
with everything to the west being served by offices in Downtown Pueblo and
everything to the east served by Vineland offices. The U. S. West technical
service areas are not fixed and can accommodate fluctuations caused by new
development.
U. S. West Communications Corporation will provide prompt service to all requests
in its service area. For most installations, the entire cost is paid for by the
developer. Upon the completion of installation, and for five years thereafter,
the developer will be entitled to refunds of part, or the entirety, of the
installation payments. This occurs when new customers use the new distribution
lines and when initial construction payments are recalculated to include the new
customer. Service to the Southeast Quadrant would be relatively simple as
distribution lines already serve a large portion of the area.
U. S. West prefers to work closely with the developer so as to efficiently serve
new customers. Such cooperation facilitates the acquisition of 20 -foot easements
for the cables and poles; it also insures the use of the most appropriate
communications system.
G. CABLE TELEVISION
The Southeast 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 the City of Pueblo, the
St. Charles Mesa area, Baxter, and Meadowbrook Mobile Trailer Park.

They are not opposed to installing cable underground and will work with the
developer 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.
.i
VII. PUBLIC FACILITIES -- EXISTING AND PROPOSED PLANS
PREFACE
Recreation, education, and public protection are community services which maintain
an area's well being, growth, and attractiveness. In turn, growth will impact the
demand for public services and facilities. Public facilities must be capable of
expanding in order to meet this increased demand and still provide consistent
quality and quantity of service.
This section will examine the school, park, fire, and police facilities and
services within the Southeast Quadrant.
A. SCHOOLS
Pueblo County has two public school districts, No. 60 and No. 70. School District
No. 60 is primarily contained within the Pueblo City limits, while School District
No. 70 encompasses the remainder of the County. District boundaries are not
precisely the same as City limits in that some "City" children go to "County"
schools and vice versa (See Map XIX).
Land use trends and recent development proposals indicate that the Southeast
_ Quadrant's proposed urban extension area will develop primarily as a mixed
commercial and industrial area. This area is not anticipated to generate an
excessive demand on schools.
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, seven (7) middle
schools, and twenty -nine (29) elementary schools. 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.
Bradford, Fountain, Fairview, Bessemer, and Spann Elementary Schools and Risley
Middle School are located within the Southeast area of the District. Bradford and
Parkview Elementary Schools are nearing capacity, and Risley Middle School, one of
the older schools in the District, is in need of repair.
East High School serves the study area. This high school would be impacted by
additional growth in the Southeast portion of the School District.
- 70 -
Table VI illustrates 1988 -1989 enrollments and school capacities for those schools
previously mentioned.
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 one high school, two middle schools, and three
elementary schools. These serve students in the study area. Enrollment figures
for 1988 -1989 are illustrated on Table VII. County High, Pleasant View, and
Vineland Middle Schools, and South Mesa, North Mesa, and Vineland Elementary
Schools can adequately serve an increasing enrollment. In addition, Baxter
Elementary School, located north of the Arkansas River on 28th Lane, is currently
closed due to insufficient enrollment. This school would be reopened if growth
warranted such action (See Map XIX).
- 71 -
School District No. 70 is not experiencing intense pressure associated with rapid
development and increasing enrollment. This may change with continuing growth
and annexation by the metropolitan area. Presently, population is lightly
concentrated along U. S. Highway 50 and sparsely distributed throughout the rest
of the County.
The schools in District No. 70 are considered "suburban" schools by the Colorado
Department of Education. Approximately, 94 percent of the students are bussed to
schools. The District identifies philosophically with neighborhood schools and
would construct additional facilities in an area to meet the demands of growth
and development.

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 (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.
Park 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
Parkways /Median: A landscaped thoroughfare providing visual relief and natural
beauty. Parkways are of considerable value in the
implementation of a recreational trail 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.
The City of Pueblo has the authority to own and maintain property for public
purposes. Parkland areas may be acquired through City purchase, property gifts,
through settlement of delinquent taxes, abandonment, easements, and through land
dedication.
Title XII, Chapter 4, Section 7(e) of the City Code of Ordinances, states that
eight percent of land subdivided for residential purposes (exclusive of street
widths) is to be dedicated as parkland. This land can be several small parks or
one large park depending on the needs of the community. If the City Council
determines that said land is not appropriate for parkland dedication, the Council
shall require a cash payment in lieu of land dedication. This payment shall be
equal to eight percent of the fair market value of the land in such subdivisions.
This payment is deposited into a special fund to meet future recreational needs in
the City.
The City Parks and Recreation Department is responsible for the development,
operation, and maintenance of recreational and park facilities. The City
Department of Planning and Development provides professional planning and landscape
design services when needed. Financing new parks and recreational development is
provided through the City's General Fund. The dollars generated by the Colorado
Lottery are deposited into the General Fund and earmarked for "allowable" parks and
recreation projects. Funding is supplemented with State and Federal grants.
Recreational facilities in the City portion of the study area consist of the
following:
Neighborhood Parks

TOTAL ACREAGE: 35.73
The County area of the study quadrant is limited to a community center serving the
Salt Creek area, a school - playground at the Fulton Heights Elementary School, and
the school -park at Baxter Elementary School (See Map XX).
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.
Currently, trails are located along sections of 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 trail 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.
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. The South-
east portion of the City is served by Station Nos. 4, 6, 9, and 10.
- 75 -
Station No. 4, located at 1201 E. Evans, is equipped with a three -way pumper truck
and an 85 -foot aerial fire truck. This station employs three, five - 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. 6, located at 1335 E. 4th Street, is equipped with a three -way pumper
truck and staffed by three, four - 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.
Station No. 10, located at the Pueblo Memorial Airport terminal area, is staffed
by three, two - person shifts and equipped with a three -way pumper truck and two
crash trucks.
Map XXI illustrates the respective protection zones.
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.
2. Pueblo Rural Fire Protection District
The County portion of the study area is contained within the Pueblo Rural Fire
Protection District.
_ The Pueblo Rural Fire District is made up of two fire stations (See Map XXI) and
serves a large area. The District has a mutual aid agreement with the City Fire
Department stating that either department will assist the other, upon request, in
the event of an emergency.
3. CF &I
CF &I has its own fire protection service. The City Fire Department has a mutual
aid agreement with CF &I (See Map XXI).
- 77 -
4. Summary
_ If build -out of the Southeast's proposed urban extension area is realized,
additional fire protection facilities, staffing, and equipment would be needed.
Airport Station No. 10 could be expanded to serve a portion of the area by
increasing the number of fire fighters per shift so that the station remains
manned during emergencies. New facilities would be needed as development density
and the area requires.
Long -range plans for the Pueblo City Fire Department are dependent upon where
development takes place, new road construction, number of buildings, density of
buildings, and other factors which may affect response time. Slow City growth has
benefited the Department, enabling precise planning decisions to be made.
D. POLICE
1. Citv 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).
When land is annexed to the City, the Police Department assumes protection of that
area from the County Sheriff. 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. Decisions to create a new beat will be based on this report.
The Southeast portion of the City is protected by four patrol routes. These
routes have been expanded to incorporate the 1988 U. S. Highway SO -B annexation.
With the addition of this annexed property, the capability of further expansion of
police service is at a minimum. Pueblo's Police Chief has stated that City
Council must review the capability of the Department's current staff to support
and serve any additional annexations to the City.
2. Countv 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 Baxter and the
St. Charles communities. They provide service to areas in the Southeast proposed
urban extension area. 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.

land uses in both the City and the County. Zoning and land
this plan reflect a desire for compatible yet flexible
-' Zoning trends in the Southeastern part of the City reflect a transition from
residential uses in the North to industrial areas in the South. The area in the
northwest corner of the Quadrant is primarily residential, with pockets of
neighborhood commercial zones. Toward the Missouri- Pacific Railroad and the
confluence of the Fountain Creek and Arkansas River, parcels tend to be industrial
and public. Continuing south is a small residential area surrounded by industrial
lands, followed by the residential areas near Lake Minnequa (See Map XXII).
B. COUNTY ZONING
Areas in the Southeast Quadrant present a wide variety of Pueblo County land use
zones. Industrial zones include the CF &I Steel Corporation and the Comanche Power
Plant. The southern portion of the St. Charles Mesa is agriculturally zoned. The
Blende community and areas adjacent to U. S. Highway 50 -C are primarily low to
medium density housing and include rural residential areas and some agricultural
uses.
These residential areas are mixed with commercial zones along U. S. Highway 50 -C.
Approaching the river from the south, zoning returns to agricultural (A -2) and
open space floodplain (S -1).
Map XXIII details current zoning in the proposed urban extension area. Here the
land begins in the west with industrial and public lands, a few residential
parcels, and then is zoned agricultural near the river. Adjacent to U. S. Highway
50 -B are several industrially zoned properties and a multiple - residential and
commercial zone which includes a nonconforming mobile home park. Baxter provides
low to medium density residential zoning with some commercial. A second multiple
residential and commercial zone containing a nonconforming mobile home park is
located between 33rd and 34th Lanes. Agricultural land continues to the eastern
boundary of the area.

C. LAND USES
1. General
Land uses in the Southeast Quadrant study area vary widely. In the study area,
land uses are primarily residential and rural residential. These are supported by
commercial uses along U. S. Highway 50 -C (Santa Fe Drive). Small scale farming is
also prevalent. Two large industries, CF &I Steel Corporation and Public Service
Company's Comanche Power Plant, are located in this quadrant.
Land uses between U. S. Highway 50 -B and the Arkansas River include Pueblo's
East Side low- density residential uses, some warehousing activities, and other
commercial uses. There is a wastewater treatment plant, mineral extraction
operations, and vacant land in the area. Continuing east, small scale industries
flank U. S. Highway 50 -B. Agricultural or vacant lands are situated between these
and the Arkansas River. There is a mobile home park, the residential community of
Baxter, and several convenience markets. Continuing east is located a second
mobile home park and agricultural uses in the study area's boundary.
2. Farm Land
The economy of Pueblo County is partially based on the farming and ranching
industry. The land in the study area supports such crops as alfalfa, corn, dry
beans, sorghum, and peppers.
The U. S. Department of Agriculture, Soil Conservation Service, was 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. Prime agricultural lands, as identified on
Map XXIV, are defined as having adequate and dependable water supply from
irrigation, a favorable temperature and growing season, acceptable acidity or
alkalinity, and acceptable salt and sodium content. Soils should be permeable to
air and water, not excessively erodible, nor excessively saturated with water.
It is recommended by this plan that those prime agricultural lands located in the
Southeast Quadrant proposed urban extension area remain as agricultural and rural
residential areas.
3. The Pueblo Memorial Airport and Airport Industrial Park
The Pueblo Memorial Airport and adjacent industrial park are located six miles
east of downtown Pueblo on 3,800 acres of land north of Highway 50 -B. Although
not in the Southeast Quadrant study area, the Airport will be discussed due to its
impact on the study area.
Pueblo Memorial Airport is classified in the National Airport System Plan as a
non -hub, medium - density, secondary air - carrier airport. It's annual aircraft
operations range falls between 100,000- 250,000 and 50,000- 100,000 annual passenger
enplanements (departures). In 1987, there were 49,177 enplaned passengers. The
Airport offers facilities 24 hours daily to both civilian and military operations.
The Airport has two runways. The main runway is 10,496 x 150 feet east /west. The
secondary runway is 7,000 x 150 feet north /south. Over 90 percent of all general
aviation and military operations occur on the east -west runway.
Isbill Associates, Inc., prepared an Airport Master Plan in 1975. Noise zones, or
those areas significantly impacted by aircraft noise, were measured by Composite
Noise Ratings (CNR's). Three zones were identified. Zone 3 - -115+ CNR's - -next to
the runway; Zone 2--100 -115 CNR's - -in the takeoff and landing areas; and
Zone 1 - -90 -100 CNR's -- outside those areas (See Map XXV). Residential land uses
were "Normally Acceptable" by Federal Aviation Administration (FAA) standards in
Zone 1, "Normally Unacceptable" in Zone 2, and "Clearly Unacceptable" in Zone 3.
CNR zones correlate to older aircraft with noisier engines, using different
takeoff and landing patterns than today's quieter more efficient planes. Pursuant
to the Airport and Airway Improvement Act of 1982, the FAA has streamlined the
process for determining noise exposure levels and land use capabilities around
airports. All Federal noise levels are now measured in Average Day -Night Sound
Levels (LDN). By using a sophisticated computer modeling program developed by the
FAA, aircraft types and takeoff and landing patterns are computed for a more
accurate depiction of today's noise levels. New noise zones were prepared in 1987
by the State Department of Local Affairs for the City of Pueblo (See Map XXVI).
By comparing the CNR 1977 Zones with the LDN 1987 Zones, one can conclude that
noise impacts have changed (See Table VIII). The LDN 1987 Zones, however, have
n been adopted as official noise zones.
Airport noise impact in the Southeast Quadrant is limited to a small portion west
of the Baxter community. This area is contained within Noise Zone 1 which is
compatible with most kinds of development (See Table I).
