ARTICLE I
Mixed Use Development Areas
/^ Sec. 26-1-10. General
A. The Mixed Use Development areas (MUD areas) provides unique and challenging opportunities for the
establishment of an on-going planning process in areas which are experiencing increased growth and development.
The presence of an interstate and state highway system and the external growth pressures from the Longmont
Metropolitan Area and the I-76 Corridor have added to the interest in land development and population growth
within these area. The intent of this Chapter is to guide and implement planned land use changes in the MUD
areas, particularly the conversion of rural lands to more intensive urban-type land uses. The regulations found in
this Chapter are intended to be implemented by the land use and development policies in the Comprehensive Plan,
Zoning Ordinance, Subdivision Ordinance and Planned Unit Development Ordinance, contained in Chapters 22,23,
24 and 27 respectively, of this Code.
B. A list of common acronyms and abbreviations utilized in this Chapter is contained in Appendix 26-A to this
Chapter. (Weld County Codification Ordinance 2000-1)
Sec. 26-1-20. Planning area boundaries
A. There are two planned areas for Mixed Use activities defined within unincorporated Weld County. One
area is located along the 1-25 corridor while the other can be found in close proximity to the I-76 corridor in
Southeast Weld County.
B. The I-25 MUD area covers approximately fifteen thousand (15,000) acres with approximate boundaries at
Weld County Road 1 on the west, Weld County Road 15 on the east, Weld County Road 32 on the north and Weld
County Road 20 on the south. The MUD The planning area boundaries are shown on Map 2.1,the I-25 Structural
Land Use Map, the most recent copy of which is on file at the Clerk to the Board's office and the Department of
Planning Services. (Weld County Code Ordinance 2001-4; Weld County Code Ordinance 2002-4; Weld County
Code Ordinance 2003-1; Weld County Code Ordinance 2004-6)
C. The Southeast Weld MUD area is located in southern Weld County along the transportation corridors of
Weld County Road 49 (WCR 49), and Weld County Road 22 (WCR 22), and is situated to participate in Weld
County's future share of commercial, industrial and residential growth. The area is in close proximity to major
regional economic generators such as Denver International Airport and the metropolitan areas of greater Denver
and Greeley. The existing transportation links of 1-76 and its existing interchanges and the County's commitment
to WCR 49 to serve as the County's only continuous north-south highway from Greeley to the south, east of
Interstate 25, all support the need to identify this area as an urban corridor. The planning area boundaries are shown
on Map 2A-XX,the Southeast Weld Structural Land Use Map, the most recent copy of which is on file at the Clerk
to the Board's office and the Department of Planning Services. (Weld County Code Ordinance 2001-4; Weld
County Code Ordinance 2002-4;Weld County Code Ordinance 2003-1;Weld County Code Ordinance 2004-6)
Sec. 26-1-30. Amendment procedure
Individuals may submit a proposal to amend the MUD Structural Plans in accordance with the procedures set
forth in Section 22-1-150 of this Code. Any applicant submitting a proposal to amend the I-25 or Southeast Weld
MUD Maps
Planning Services, shall also submit a deed or legal instrument to the Department of Planning Services identifying
their interest in the property.
Sec. 26-1-40. Existing services
The MUD areas are is intended to be areas which will accommodate development that may occur as a result of
the planned infrastructure and services existing and developing. in-the-erg The tables at Appendix 26-B and
Appendix 26-C to this Chapter display the existing service providers in the MUD areas.
Sec. 26-2-69-50 PUD Districts in MUD areas
A. Intent. The PUD provisions shall be applied to all proposals for commercial, industrial and residential
developments within the MUD areas,with the exception of those developments specifically called out and excluded
in this policy document. All PUD Districts in the MUD areas shall adhere to the procedures and requirements
outlined in Chapter 27 of this Code.
1
B. Exemptions from the PUD District Provisions.
1. The following uses are exempt from utilizing the PUD process within the MUD areas and will require a
Use by Special Review(USR)application:
a. Sand and gravel mining operations.
b. Home businesses as defined in Chapter 23 of this Code.
c. Agricultural service establishments primarily engaged in performing agricultural, animal husbandry or
horticultural services on a fee or contract basis, including such uses as outlined in Section 23-3-40 B of this
Code.
d. Those uses which were legally created prior to the PUD requirement and located on a single legally
created lot.
2. The following land use applications are exempt from utilizing the PUD process in the A (Agricultural)
Zone District within the MUD areas:
a. Recorded exemption in the A(Agricultural)Zone District.
b. Subdivision exemptions.
c. Amendments to recorded exemptions and subdivision exemptions.
d. Zoning permits for mobile homes.
e. Zoning permits for accessory dwellings.
f. Manufactured home zoning permits.
g. Certificate of compliance.
h. Flood hazard and geologic hazard development permits. (Weld County Code Ordinance 2002-9)
Sec. 26-240 60 General.
A. Recent activity in the MUD areas has accelerated and reinforced the need for long-term approaches to
planning. in the region. This increase in development has resulted in the creation of development standards to
regulate these areas. These development standards shall apply to all structures and land within the MUD areas as
shown on the MUD Structural Land Use Map 2.1 and the Southeast Weld Structural Land Use Map XX, the most
recent copy of which is on file at the Clerk to the Board's Office and the Department of Planning Services. These
regulations provide development standards to implement the goals and policies in the Mixed Use Development
section of Chapter 22 of this Code.
Sec.26-2-2070Intent.
A. The intent of these regulations is to ensure the compatibility of various land uses, buildings or structures
within the MUD areas. These regulations are intended to allow flexibility and encourage creativity in development
of the areas in regard to density, height of structures, setbacks and common open space. The development
standards found in this plan are the minimal development standards allowed in the MUD areas.
Article II I-25 MUD
Sec 26-2-10 Development Standards
A.$.In the I-25 MUD, land use designations are grouped into five (5) structural land use categories. These
categories are conceptual designations and shall not be interpreted or construed to give rise to any vested rights in
the continuation of any particular use,district, zoning classification or any permissible activities therein.
B. C. Structural land use categories:
1. Employment centers. 1
2. Regional commercial.
3. Neighborhood centers.
2
4. Residential neighborhoods.
5. Limiting site factors.
C. Each structural category consists of distinct and unique qualities and is established as a matter of policy to
guide and implement planned land use development. These categories are further defined in Section 26-2-20 below
and are delineated on the I-25 MUD Structural Land Use Map 2.1, the most recent copy of which is on file at the
Clerk to the Board's office and the Department of Planning Services. The correlation of the categories to
generalized zone districts as defined in Chapter 23 of this Code are outlined in the table at Appendix 26-C to this
Chapter. In all cases, Chapters 23,24 and 27 should be consulted for clarification of specific requirements.
Sec. 26-2-30-20. I-25 MUD Structural land use categories
A. Employment Centers.
1. The structural land use plan provides a unique opportunity to create major centers of new employment in
the MUD areas, which employment centers are linked and orientated toward the network of regional and
national roadways serving the area. Employment centers are orientated around major roadways to allow for
goods and services to the traveling public. These centers may also accommodate high-intensity industrial uses
which create minimal negative visual impacts.
2. Employment centers characteristically have high transportation impacts and environmental concerns such
as noise, dust and pollution. Even with the associated impacts, these centers are intended to provide pleasant
and safe environments for employees and visitors through planning and design standards. Outdoor eating and
seating areas, pedestrian mutes within parking lots and other pedestrian amenities should be provided for
employees and visitors. Employment centers include,but are not limited to,the following activities and services
in higher density commercial and industrial zone districts:
a. Hotels and motels.
b. Restaurants,including drive-in restaurants.
r
c. Utility service facilities.
d. Police and fire stations.
e. Any use of a research, repairing, manufacturing, fabricating, processing, assembling or storage nature
as long as the use is conducted entirely within enclosed buildings.
B. Regional Commercial Centers. Regional commercial centers are intended to provide safe, efficient areas
offering convenience goods and services to residents of surrounding neighborhoods. These centers include
commercial and industrial activities which are medium-intensity levels and have few environmental and service-
related impacts. Activities in these centers may include the following:
1. Retail shops.
2. Civic uses such as libraries,community centers and churches.
3. Service businesses such as offices.
4. Public facilities and utility service facilities.
5. Restaurants.
6. Retail and wholesale establishments.
7. Light manufacturing and research facilities.
C. Neighborhood Centers. Neighborhood centers are established to provide convenience goods and services
primarily for the residents of a specific neighborhood. These centers should be accessible via sidewalks, trails or
greenways, creating identity for individual neighborhoods. Neighborhood centers characteristically have few
environmental impacts and rely more upon service-related provisions such as law enforcement and fire protection.
New development within these centers shall therefore mitigate the impacts associated with its use. Neighborhood
centers include,but are not limited to,the following activities and services:
3
1. Small parks.
2. Civic uses,such as places of worship,libraries and community centers.
3. Public facilities, such as schools.
4. Service businesses, such as smaller offices.
5. Residential mix.
D. Residential.
1. Residential districts within the-this MUD area are encouraged to be cohesive, identifiable and diverse,
while retaining the current agrarian lifestyle of residents in the area. The County encourages comprehensive and
coordinated neighborhood design efforts in developments, especially with regard to circulation provisions,
conservation of natural features and relationship to established neighborhood centers. The County also
encourages diversity of housing types, including owner-occupied and rental housing, which serve all economic
segments of the population and match local incomes and age groups. Higher residential densities shall be
situated within close proximity to the designated neighborhood centers. Each neighborhood shall have an
interconnected network of local streets that provide direct connections to local destinations.
2. The successful design and development of residential neighborhoods within the-this MUD area is
essential for it to function efficiently and provide a sense of place and community identity. Developments are
encouraged to incorporate design features which enhance the quality of the neighborhood and promote safety for
its residents. An example of various design considerations for subdivisions is illustrated at Appendix 26-D to
this Chapter.
E. Limiting Site Factors.
1. Areas comprised of limiting site factors contain certain physical elements that obstruct or are hazardous
to certain types of development. These physical elements include floodplain, critical wildlife habitat areas,
aquifer recharge, riparian areas,topographical constraints and other similar inhibiting elements. Although these
sites contain factors which limit certain types of development, these areas are nevertheless usable for
agricultural production, recreational activities and parks, or other functions that cannot damage or be damaged
by the constraining site factors. These areas can also enhance the character of the-this MUD area by providing
corridors for trails and wildlife, and for the protection of natural resources, riparian habitats and natural features
essential to the identity of the-this MUD area.
2. Land designated as having limiting site factors on the I-25 Structural Land Use Map 2.1,the most recent
copy of which is on file at the Clerk to the Board's office and the Department of Planning Services, are primarily
defined by the one-hundred-year floodplain(as defined by FEMA Flood Insurance Rate Maps) which comprises
approximately four thousand five hundred (4,500) acres, or thirty-eight percent (38%) of the total designated
area in the-this MUD area. Sites shown with limiting factors also incoipu,ate other important natural features as
well, including wildlife habitat, mature riparian areas, primary drainageways and sand and gravel resources.
Therefore, additional land containing limiting site factors is shown along irrigation canals and ditches and
adjacent to lakes. To the maximum extent practical, development within areas having limiting site factors shall
be located to preserve the natural features of the site,to avoid areas of environmental sensitivity and to minimize
negative impacts and alteration of natural features.
Sec.26-2-4630 Common open space regulations.
A. All Planned Unit Developments (PUDs) within the I-25 MUD area shall preserve a portion of the site as
common open space. Common open space is defined as any usable parcel of land or water essentially unimproved
and set aside, dedicated,designated or reserved for public or private use or enjoyment or for the use and enjoyment
of owners or occupants of land adjoining or neighboring such an area. Common open space includes landscape
areas that are not occupied by buildings or uses, such as storage or services areas, private courtyards, parking lots
and islands. In all PUD districts except for those containing residential uses, common open space may include
landscape setbacks adjacent to roadways, where the setbacks are not utilized as parking or storage areas. Common
open space is not to be included in the calculation of the maxim=coverage per lot. The minimum percentages of
land in each development devoted to common open space is listed in Appendix 26-E to this Chapter. Department
of Planning Services' staff reserves the ability to evaluate development design proposals with less common open
4
space than listed in Appendix 26-E. The staff will determine if the proposed common open space meets the intent
of the requirements in this Chapter.
B. Common open space shall be delineated in the sketch plan phase of the PUD process. See the example at
Appendix 26-F. In areas preserved as common open space, a detailed description of the types of grass and
landscaping which will be utilized and the maintenance schedule for such landscaping shall be submitted to the
Department of Planning Services.
C. Cash-in-lieu of Common Open Space Regulation. In lieu of the preservation of land for on-site common
open space, and subject to the discretion of the Board of County Commissioners,the applicant may utilize the cash-
in-lieu of common open space option outlined in Section 27-6-80 B.8 with terms defined in Chapter 27, Article U
of this Code. This option shall be outlined in the sketch plan application to the Department of Planning Services.
(Weld County Code Ordinance 2001-1)
Sec.26-2 50 40. Maximum lot coverage regulations.
All land use applications in the I-25 MUD area shall adhere to the regulations governing the maximum
percentage of lot coverage. The maximum lot coverage is defined as the maximum percent of the total area of a lot
in a zone district that shall be covered by any structure. Land shall not be deemed covered if it is used for growing
grass, shrubs,trees, plants or flowers it is covered by decorative gravels or wood chips, or if it is otherwise suitably
landscaped. The percentage of coverage on a lot shall not include the area of the lot or development designated as
common open space as outlined in Appendix 26-E. The percentages outlined in Table 26.1 and Table 26.2 below
shall be deemed the maximum lot coverage for each zone district within the MUD areas
Table 26.1
Maximum Lot Coverage in the 1-25 MUD areas

R-1,Estate,A* 50%
11-2,R-3,R-4,R-5 60%
*Agricultural zone districts in platted areas.
Sec.26-240.50 Landscaping regulations.
A. Intent. Landscaping is extremely important for ensuring the quality of development in the I-25 MUD areas.
Trees, shrubs and other plantings add greatly to the aesthetic appeal while controlling erosion, reducing glare,
lowering temperatures, buffering sounds and blocking or diverting wind. As no single landscaping plan can be
prescribed for all developments due to differing land features, topology and soils, the County allows flexibility and
encourages creativity in landscape designs. Landscaping must be sensitive to the characteristics and maintenance
requirements of the planting selected. Species must be chosen that are hardy for the climate and soil conditions in
the MUD areas,that can tolerate traffic,that are resistant to disease and insects, and whose maintenance needs can
be met. The following landscaping standards set minimum requirements for all developments within the MUD
areas.
B. Design Criteria.
1. Landscapes shall utilize the following principles for maximum use of water: (a) well-planned and
approved planting schemes; (b) appropriate selection of drought-tolerant turf species to minimize water needs
and the use of water-hungry species of turf; (c)mulch to reduce evaporation; (d)zone plant groupings according
to their microclimatic needs and water requirements; (e)improvement of the soil with organic matter if needed;
(f) efficient irrigation design; and(g)proper maintenance and irrigation scheduling.
2. Landscapes shall consist of a variety of species. A partial list of plant materials that are native or adapted
to Colorado's Front Range is included in Appendix 26-G. Plant materials that are discouraged within this area
include:
a. Cotton-bearing cottonwoods(Populus).
b. Siberian and Chinese elm((Emus).
5
c. Tree of Heaven(Allianthus).
d. Russian olive(Eleagnus angustifolia).
e. Purple loosestrife(Lythrum salicaria).
f. All plants identified as noxious plants in Chapter 15 of the Weld County Code.
3. Buildings and parking areas shall be located to preserve and promote the health of existing trees. The
applicant shall be responsible for locating and preserving,where feasible, all individual trees of four-inch caliper
in size or larger, and massed groups of small trees. Before construction,the following precautions shall be taken
to preserve quality trees:
a. The applicant shall submit to the Department of Planning Services a detailed Landscape Plan
delineating the existing and proposed trees, shrubs,ground covers, natural features such as rock outcroppings
and other landscaping elements. The Plan shall show where landscaping exists or will be located, along with
planting and construction details. Where existing plantings are to be retained, the applicant shall include in
the plans proposed methods of protecting the plantings during construction
b. The applicant shall demonstrate to the Department of Planning Services that the maximum possible
landscaping was preserved or relocated through the development process.
c. Heavy equipment shall be kept at least five (5) feet from tree drip lines to prevent tree roots from
being damaged.
4. Whenever the use of the property to be developed or redeveloped will conflict with the use of adjoining
property,there shall be an opaque planted screen between the two(2) properties. The screen shall moderate the
impact of noise,light, aesthetic concerns and traffic.
5. All landscapes shall strive to maximize the use of native species. Where native material is not
appropriate for the intended use or appearance, plant species that are regionally adapted and noninvasive shall
be used.
6. Fescue,brome/fescue or other turf types shall be used in lieu of bluegrass where heavy foot traffic is not
anticipated. Seeding versus sodding of all turf types is preferred when the growing season allows for adequate
germination and establishment of the turf to sufficiently control erosion.
7. Landscape areas shall be configured to maximize their interconnectivity within the site, to natural areas
and to landscape areas within existing or future adjacent development. Small isolated islands of landscaping
except as required in parking lots and for screening along roadways shall be avoided. Open space shall be
provided where significant natural features exist.
C. landscaping Requirements for Parking Lots.
1. At least ten percent(10%) of the area of a parking lot must be landscaped if the lot contains ten(10) or
more spaces. The requirement may be counted toward the maximum lot coverage requirement of each zone
district. At least seventy-five percent(75%)of the required landscape area shall include living plant material.
2. Berming and shrub or tree planting shall be used to screen parking lots from view of the roadway. Berms
can vary in height depending on location and proximity of existing trees. Berns shall have smooth transitions
from the top of the curb to the setback line so as to not create snow traps, with allowances made for placement
of the sidewalk. Grading of berms shall not be lumpy or abrupt. See Appendix 26-H to this Chapter.
3. Landscaping techniques shall be used to alleviate the harsh visual appearance that accompanies parking
lots. See Appendix 26-I to this Chapter. At least seventy-five percent(75%)of the length of the frontage of the
parking lot mist be effectively screened.
4. A minimum of five percent (5%) of the parking area shall be landscaped exclusive of setback areas.
Trees planted in parking areas should be either in bays or planting islands of at least five(5)feet by five(5)feet.
Trees should be distributed throughout the parking area; however, they shall be placed so that they do not
obstruct visibility for cars and pedestrians. Generally every tenth parking space should be delineated with a
planting island in addition to the 5%. See Appendix 26-J to this Chapter.
6
5. Loading, service or storage areas must be screened with an opaque screen that is an integral part of the
building architecture. Chain link fencing with slats, fabric or pallets are not an acceptable screening material.
Plant material shall be used to soften the appearance of the screen.
D. Landscaping Requirements along Roadway Corridors.
1. Intent. The major roadway corridors within the this MUD area are I-25, State Highway 119, State
Highway 66 and Weld County Road 1 and all strategic roads as delineated by the Weld County Strategic
Roadways, dated December 2004. These roadways play an important role in the function and image of the
MUD areas. The following design standards relate to the visual quality of these four (4) roadways. As the
MUD areas develop, additional roadways may require similar consideration as these existing major roadway
corridors. This determination will be made by the Department of Public Works and the Colorado Department of
Transportation. All roadways that are not considered major roadway corridors are considered secondary
roadways.
2. Design Criteria.
a. Plantings along road rights-of-way shall be integrated with the rest of the site.
b. That portion of a lot in any zone district which abuts a public or private road right-of-way shall be
landscaped with a minimum two-and-one-half-inch caliper shade tree or six-foot minimum height coniferous
tree at a distance of ten(10)feet,measured at a right angle from the lot line towards the interior of the lot, for
every forty (40) linear feet of street frontage. Trees may be grouped with a maximum distance of one
hundred(100)feet between trees or groupings, with exceptions made at entrance drives.
c. A minimum landscape setback along I-25, SH 119 and all strategic roads, and their subsequent
frontage roads shall be fifty(50)feet measured from the existing or planned future right-of-way.
d. Along I-25, SH 119, SH 66. and WCR 1 and all strategic roads, tree planting distances shall be
clustered or grouped from the roadway to avoid a straight line of trees. The effectiveness of the screening
shall be increased by planting trees and shrubs in layered beds (two [2] or more rows of plant material rather
than a single row). A mix of coniferous and deciduous trees and shrubs shall be planted in clusters or
groupings.
e. Applicants adjacent to I-25 and/or SH 119 shall construct a berm along I-25 and/or SH 119 with
maximum 5:1 side slopes to a height sufficient to screen ground plane development (parking lots, storage
areas or other similar site elements) as far as one hundred eighty(180) feet from the right-of-way line (fifty
[50]feet of landscape setback plus one hundred thirty [130] feet of site development). The maximum height
berm required shall be six (6) feet above the existing elevation in the location of the berm. If needed,
additional height beyond that which can be achieved with a six-foot-high berm shall be achieved through
dense landscape plantings. Plantings on top of bums shall be designed so as to not create snow traps. A
berm may not be required if the subject property is elevated above the roadway and it can be demonstrated
that views into the site will not be possible for a distance of one hundred eighty (180) feet. Required
landscaping and screening within the landscape setback and other portions of the property shall be governed
by the landscape standards contained within this Chapter and any other more restrictive requirements
contained in Chapters 23 and 24 of this Code.
f. There shall be a minimum twenty-five-foot-wide landscape setback along SH 66, and WCR 1 and all
strategic roads, measured from the existing or planned future right-of-way.
g. There shall be a minimum twenty-foot-wide landscape setback measured from the existing or planned
future right-of-way to any parking lot, fencing, storage area or structure. Required landscaping and
screening within the landscape setback and other portions of the property shall be governed by the landscape
standards contained within this Chapter and any other more restrictive requirements contained in Chapters 23
and 24 of this Code.
h. Appendices 26-M through 26-P to this Chapter illustrate the proposed character, berming and
landscape setbacks for the I-25 and SH 119 corridors. (Weld County Codification Ordinance 2000-1)

Sec. 26-240.60 Transportation and circulation regulations.
A. Intent. As transportation demands increase in the I-25 MUD area, the need to preserve the functional
integrity and hierarchy of the existing roadways and provide new roadway capacity is becoming increasingly
important. The purpose of this Section is to provide for the planning, design and construction of improvements to
new and existing roadway facilities consistent with Chapters 22, 23, 24 and 27 of this Code. The intent of these
standards is to provide for a certain level of performance. Consequently, if it can be shown that an alternate design,
material or procedure will provide performance equal to or better than the required design, material or procedure,
that alternate may be approved by the Director of Public Works.
B. Traffic Impact Analysis. All significant developments within the MUD areas shall be required to prepare a
traffic impact analysis. All traffic analysis information and reports shall be prepared and certified to by a registered
professional engineer competent in traffic engineering. The intent of this analysis is to determine the project's
cumulative development impacts, appropriate project mitigation and improvements necessary to offset a specific
project's impacts. The County may require the developer to contribute for payment of the costs of said
improvements through an improvements agreement. All traffic impact analysis shall contain, as a minimum, the
following information:
1. Introduction: Describe the proposed development and parameters of the study area.
2. Existing Conditions:
a. The street capacity standard in the MUD areas is Level of Service C and the intersection capacity is
Level of Service D.
b. Conduct a.m. and p.m. peak hour turn movements and average daily traffic counts for intersections
and links within the study area if there are no available counts collected within the previous twelve (12)
months.
c. Conduct a peak hour intersection level of service analysis for the intersections.
d. Determine whether the existing daily traffic volumes exceed the arterial daily volume standards as ^�
identified in the MUD street standards for major arterial, arterial, secondary, collector and local streets
presented in Appendix 24-E, Roadway Cross-Sections, to Chapter 24 of this Code. These standards
delineate right-of-way,lane configurations,median treatment,bike lanes and pedestrian sidewalks.
3. Cumulative Conditions:
a. Identify previously approved or anticipated developments that may affect the study area's circulation
system.
b. Generate, distribute and assign traffic to the existing roadway network.
c. Determine annual growth rates and project future traffic volumes for the time frame corresponding to
project build-out.
d. Identify funded circulation improvements,both public and private,that will be constructed prior to the
proposed development's occupancy.
e. Conduct a peak hour intersection level of service analysis and compare daily volume forecasts to street
standards assuming cumulative developments, annual growth rates and funded improvements.
f. Determine mitigation measures to offset cumulative conditions if level of service exceeds the MUD
areas standards.
4. Trip Generation: Determine daily and a.m. and p.m. peak hour trip generation for the proposed

Transportation Engineers or as agreed to with County staff.
5. Trip Distribution: Based on assumptions contained in the MUD areas traffic analysis or market —.
estimates, describe the anticipated trip distribution patterns for the proposed development.
6. Trip Assignment: Based on the projected trip generation, assumed trip distribution and the prevailing
8
roadway network, assign the projected traffic to the intersections and streets within the study area.
7. Existing+Committed+Project(E+C+P)Traffic Volumes and Level of Service:
a. Add project a.m. and p.m. peak hour and daily traffic volumes to existing plus committed traffic
volumes.
b. Conduct intersection level of service analysis and determine whether daily traffic volumes exceed
street standard thresholds.
8. Signal Warrant Analysis:
a. The I-25 MUD Transportation Network Map 2.2,the most recent copy of which is on file at the Clerk
to the Board's office and the Department of Planning Services identifies future locations for signalization;
signals,however, should not be installed prior to when they are needed.
b. Using the AASHTO Manual on Uniform Traffic Control Devices (MUTCD), determine whether
proposed intersection volumes exceed signal warrants for those locations on the transportation network
where signals are proposed.
9. Access: Projects involving access to the state highway system shall indicate appropriate conformance to
the latest revisions of the State Highway Access Code. The report shall discuss how the proposed development
meets the access control guidelines as presented in Section 4.4.2 of the MUD Background Document, available
at the Department of Planning Services.
10. Mitigation Measures: Mitigation measures will be to implement the needed improvements to offset
project impacts as determined by the traffic impact analysis.
C. Design Standards.
1. All development within the MUD areas shall comply with Chapters 22, 23, 24 and 27 of this Code and
the Colorado State Highway Access Code, 2 CCR 601-1. Consistent with the urban-scale development
standards in the MUD areas, all parking areas for commercial and industrial development shall be paved
according to geometric and road structure design standards.
2. Geometric Design Standards. Geometric design for streets and roads shall be in accordance with A
Policy on the Geometric Design of Highways and Streets published by the American Association of State
Highway and Transportation Officials. Specifications, standards or design criteria published by the other
governmental agencies, professional organizations or generally accepted authoritative source may be used in
geometric design. All specifications, standards, or design criteria shall be referenced and copied as part of the
submittal information.
3. Road Structure. Structural capacity shall be designed in accordance with the Guide for Design of
Pavement Structures published by the American Association of State Highway and Transportation Officials.
Specifications, standards or design criteria published by other governmental agencies, professional organizations
or generally accepted authoritative source may be used in design. All specifications, standards or design criteria
shall be referenced and copied as part of the submittal information. All roads shall adhere to the standards set
forth in Chapter 24, Article VII of this Code.
4. Structural Road Improvements. Adjacent roadways shall be designed to meet the full typical section
specified in the County Transportation Plan and Chapter 24 of this Code. Improvements may include the
construction of travel lanes, shoulders,bike lanes, medians, curb, gutter and sidewalks, for example. Required
improvements may also include the acquisition of right-of-way and construction easements that will be
dedicated to the public. Improvements attributed to the development shall be consistent with the direct impact a
particular development has on the County mad system, as determined by a professional transportation study.
The road improvements agreement and roadway construction plans shall be considered by the Board of County
Commissioners.
r D. Circulation System.
1. The proposed MUD circulation system is presented at Map 2.2, the most recent copy of which is on file
at the Clerk to the Board's office and the Department of Planning Services. The transportation network reflects
a hierarchy of roads,from a major arterial which serves both the regional and local traffic with higher speeds9
and capacities with controlled private access, to a collector which serves local traffic and provides access to
future development. The proposed hierarchy of roads includes both reconstruction and/or widening of existing
roads and alignments for new roads. The transportation network also identifies locations of future signals.
2. The MUD roadway cross-sections are identified at Appendix 24-E, Roadway Cross-Sections, to Chapter
24 of this Code. Roadway classifications may change as development in the MUD areas occurs. Roadway
classifications may be re-evaluated by the Director of Public Works with the results of the traffic impact
analysis. (Weld County Codification Ordinance 2000-1;Weld County Code Ordinance 2001-1)
Sec. 26-2-90.70 Sign district regulations.
A. Intent. Within the I-25 MUD areas, signage has become an increasingly important issue, especially along
traffic corridors such as I-25, SH 119 and Weld County Roads 22 and 49. While signs serve as important
directional, informational and advertising tools, the clustering of signs may obscure the landscape and confuse and
distract drivers. Signage con are intended to protect and preserve the visual quality of the roadways within the I-25
MUD areas while preventing the obstruction of traffic visibility and confusion from improperly placed and
designed signs. These provisions control the magnitude, placement and number of signs in the 1-25 MUD area.
These regulations can be found in Section 23, Article IV of this Code.
Sec.26-2400.80 Utility,infrastructure and public facility regulations.
A. Intent. By their nature, most utility services are highly regulated. This regulation encompasses ownership,
financing,competition, cost recovery,construction, environmental protection and safety. Given this regulatory and
legal environment, well-established federal, state, county and industry standards/codes exist that govern most
aspects of utility service. The intent of this Section is to provide additional regulations and standards for water
supply to meet fire flow demands and solid waste collection service, and to provide standards for public facilities
and services throughout the MUD areas.
B. Water Supply and Sewage Disposal. The specifications of water supply requirements for fire protection
within the I-25 MUD. areas are provided by the Mountain View Fire Protection District. The Mountain View Fire
Protection District shall be consulted concerning the fire district's fire requirements. Chapter 22 of this Code
specifies that the water supply system serving a proposed development site or zone district must deliver a minimum
of five hundred (500) gallons per minute at twenty (20) pounds per square inch residual pressures for thirty (30)
minutes. The St. Vrain Sanitation System, a private sanitation system, shall service all sewage disposal within the
I-25 MUD areas for uses except those specifically called out and exempted from the PUD process in Section 26-2-
60 of this Chapter. C. Solid Waste. Residential and commercial solid waste collection services in the area shall
be arranged directly between solid waste disposal firms and property owners/managers. Solid waste disposal shall
be accomplished by collection firms at licensed disposal facilities.
D. Storm Drainage Design and Technical Criteria. The County does not publish technical data or storm
drainage design manuals. The consulting engineer for the developer is to use published material by a generally
accepted authority approved by the Director of Public Works. The material used must be referenced and copied as
part of the submittal information. All development within the MUD areas shall adhere to the Storm Drainage
Design and Technical Criteria regulations in Section 24-7-130 of this Code.
E. Schools.
Article III Southeast Weld MUD
Sec.26-2-3-10.General.
Recent activity in the MUD areas has accelerated and reinforced the need for long-term approaches to planning.
in the region. This increase in development has resulted in the creation of development standards to regulate these
areas. These development standards shall apply to all structures and land within the MUD areas as shown on the
MUD Structural Land Use Map 2.1 and the Southeast Weld Structural Land Use Map XX,the most recent copy of
which is on file at the Clerk to the Board's office and the Department of Planning Services. These regulations
provide development standards to implement the goals and policies in the Mixed Use Development section of
Chapter 22 of this Code.
10
Sec.26-2-3-20.Intent.
The intent of these regulations is to ensure the compatibility of various land uses,buildings or structures within
the Southeast Weld MUD area. These regulations are intended to allow flexibility and encourage creativity in
development of the areas in regard to density, height of structures, setbacks and common open space. The
development standards found in this plan are the minimal development standards allowed in the Southeast Weld
MUD area.
A. This MUD area will be a balanced and sustainable community that integrates the traditional rural heritage
of Weld County into all aspects of the community. It is the intent of the area to fit within the landscape of southern
Weld County by preserving prime irrigated agricultural land for use by local farmers and by providing a transition
of land uses that focus the high densities in the center and lower density along the perimeter, and by incorporating a
prairie style character into the theming of the community.
B. This MUD area will include a variety of land uses that are organized around a passive and active open
space system and an ongoing agricultural element. There will be a diversity of housing types enabling citizens
from a wide range of economic levels and age groups to live within the community, as well as some commercial
and retail services to address the needs of the residents.
C. Neighborhoods within this MUD area will vary within the community and may include one-acre cluster
lots adjacent to existing agricultural areas and traditional single-family lots, as well as areas for higher density town
homes. The character of the neighborhood commercial services shall be reminiscent of that found in rural
communities throughout the west: limited public ancillary facilities such as a library satellite facility and/or fire
station; a grange hall for local gatherings or farmer's markets, agricultural businesses and other neighborhood
convenience services and businesses; as well as a variety of high to higher density housing.
Sec. 26-3-30. Southeast Weld MUD Structural Land use categories.
In the Southeast Weld MUD area, land use is grouped into six categories. These categories are conceptual and
not intended or construed to give rise to any vested rights in the continuation of any particular use, district, zoning
classification or any permissible activities therein.
A. Structural land use categories:
1. Main Street.
2. Commercial Centers.
3. Main Street Villages.
4. Residential neighborhoods.
5. Agricultural lands.
6. Limiting site factors.
B. Each structural category consists of distinct and unique qualities and is established as a matter of policy to
guide and implement planned land use development. These categories are further defined in Section 26-2-30 below
and are delineated on the Southeast Weld Structural Land Use Map XX2-1-,the most recent copy of which is on file
at the Clerk to the Board's Office and the Department of Planning Services. The correlation of the categories to
generalized zone districts as defined in Chapter 23 of this Code are outlined in the table at Appendix 26-C to this
Chapter. In all cases, Chapters 23, 24 and 27 should be consulted for clarification of specific requirements.
C. Contiguous open space that provides a balanced mix of active and passive recreational opportunities will be
an integral element of this MUD area and will be clustered in order to provide for meaningful open space corridors,
which will include an extensive trail system that links the neighborhoods to local amenities such as schools and
r parks. This open space shall be located on the Southeast Weld MUD Structural Land Use Map.
D. Each structural category consists of distinct and unique qualifies and is established as a matter of policy to
guide and implement planned land use development. These categories are further defined as follows and are
11
delineated on the Southeast Weld MUD Structural Land Use Map 2.1,the most recent copy of which is on file at
the Clerk to the Board's office and the Department of Planning Services. The correlation of the categories to
generalized zone districts as defined in Chapter 23 of this Code are outlined in the table at Appendix 26-C to this
Chapter. In all cases,Chapters 23,24 and 27 should be consulted for clarification of specific requirements.
1. Main Street
1. A Main Street created in the heart of the SE Weld MUD will serve the neighborhood commercial and retail
needs of the community. This town center should be reminiscent in character of rural communities
throughout the West.
2. Small-scale, integrated commercial centers within the Main Street shall be appropriately located and sealed
to improve the livability of residential neighborhoods, while avoiding strip development patterns and
avoiding the creation of destination retail or business uses serving areas beyond the immediate community.
Commercial uses should not exceed a 0.25 floor area ratio. Uses within the Main Street may include the
following:
A. Banks
B. Day care centers
C. Offices
D. Personal service establishments
E. Restaurants
F. Retail sales
G. Civic and cultural facilities
H. Places of worship
I. Clubhouse and recreational facilities
J. Public gathering areas
3. Site design techniques should be incorporated that provide convenient vehicular and pedestrian access to
the neighborhood commercial areas from adjacent residential neighborhoods.
2. Commercial Centers
1. Commercial uses will be allowed in the residential designated lands within this MUD area as
provided for by the Weld County Comprehensive Plan. These uses will consist only of neighborhood oriented
businesses that will support goods and services for the residential neighborhoods and are envisioned to be located
around the junction of WCR 49 and WCR 22.
2. Commercial uses that would serve a greater area than the Pioneer community and would create
undesirable impacts such as traffic would not be considered appropriate in the"Residential"designation. Regional
commercial development will be encouraged in existing Towns and along the Interstate-76 corridor.
3. Commerical Centers characteristically have high transportation impacts and environmental issues
such as noise, dust and pollution. Even with the associated impacts, these centers are intended to provide pleasant
and safe environments for employees and visitors through high planning and design standards. Outdoor eating and
seating areas, pedestrian routes within parking lots, and other pedestrian amenities should be provided for
employees and visitors. Employment centers include, but are not limited to,the following activities and services in
higher-density commercial and industrial zone districts:
a. Hotels and motels.
b. Restaurants,including drive-in restaurants.
c. Utility service facilities.
d. Police and fire stations.
12
e. Any use of a research, repairing, manufacturing, fabricating, processing, assembling or storage nature
as long as the use is conducted entirely within enclosed buildings.
3. Main Street Villages
1. Main Street Villages are intended to provide safe, efficient areas offering convenience goods and services
to residents of surrounding neighborhoods. These centers include commercial and industrial activities which are
medium-intensity levels and have few environmental and service-related impacts. Activities in these centers may
include the following:
a. Retail shops.
b. Civic uses such as libraries,community centers and churches.
c. Service businesses such as offices.
d. Public facilities and utility service facilities.
e Restaurants.
f. Retail and wholesale establishments.
g Light manufacturing and research facilities.
4. Residential Neighborhoods
1. Residential districts within the this MUD area are encouraged to be cohesive, identifiable and diverse,
while retaining the current agrarian character of residents in the area. The County encourages comprehensive and
coordinated neighborhood design efforts in developments, especially with regard to circulation provisions,
conservation of natural features and relationship to established neighborhood centers. The County also encourages
�-. diversity of housing types, including owner-occupied and rental housing, which serve all economic segments of the
population and match local incomes and age groups. Higher residential densities shall be situated within close
proximity to the designated neighborhood centers. Each neighborhood shall have an interconnected network of
local streets that provide direct connections to local destinations.
2. Residential development within the MUD is clustered in such a way as to protect and preserve large
contiguous areas of open space, prime irrigated agricultural land,important natural resources and scenic views.
The intent is to include a mix of densities to create variation and options within the neighborhoods being created,
ranging from low density rural estate lots(1 du/ac)up to medium density areas(10 du/ac)envisioned within and
near the center or core area as defined by the intersection of WCR 49 and WCR 22. Appropriate neighborhood
commercial services permitted under the Comprehensive Plan's definition of Residential will be located at this
general intersection. All uses within the Residential land use category will utilize public sewer service.
3. The residential diversity incorporates single-family detached homes, attached single-family homes and
multi-family homes. The community elements of a neighborhood such as active parks, passive open space, public
and civic facilities including but not limited to schools,utilities, roadways,fire protection,law enforcement and
places of worship,will be permitted uses within the residential land use designation. All uses will have good
pedestrian connectivity and accessibility.
4. The successful design and development of residential neighborhoods within the this MUD area is
essential for it to function efficiently and provide a sense of place and community identity. Developments are
encouraged to incorporate design features which enhance the quality of the neighborhood and promote safety for its
residents. An example of various design considerations for subdivisions is illustrated at Appendix 26-D to this
Chapter. These neighborhoods should be accessible via sidewalks, trails or greenways, creating identity for
r. individual neighborhoods. Residential areas characteristically have few environmental impacts and rely more upon
service-related provisions such as law enforcement and fire protection. New development within these locations
shall therefore mitigate the impacts associated with its use. Residential neighborhoods include, but are not limited
to,the following activities and services:
13
1. Small parks.
2. Civic uses, such as places of worship, libraries and community centers.
3. Public facilities, such as schools.
4. Service businesses, such as smaller offices.
5. Residential mix.
5. Agriculture Land Use
A. Approximately 1,400 acres of this MUD area will remain agricultural. Lands that are currently
Irrigated and have the necessary soil characteristics will continue to be used for agriculture purposes. Through
the use of alternative irrigation methods the identified agricultural lands will remain a viable and important asset
to Weld County. The effluent from the proposed treatment facility located in this MUD area will be a source of
water that can be managed as part of a re-use management plan that will make water available for irrigation
within this MUD area as well as the potential for providing some assistance for the agricultural property and
downstream agricultural wells within the Box Elder basin. The water that will serve this MUD must be treated
and released in Weld County,providing a source of groundwater recharge that can be a benefit for agricultural
wells and crop producing areas within Weld County.
6. Limiting Site Factors.
A. Areas comprised of limiting site factors contain certain physical elements that obstruct or are
hazardous to certain types of development. These physical elements include floodplain, critical wildlife habitat
areas, aquifer recharge,riparian areas,topographical constraints and other similar inhibiting elements. Although
these sites contain factors which limit certain types of development, these areas are nevertheless usable for
agricultural production, recreational activities and parks, or other functions that cannot damage or be damaged
by the constraining site factors. These areas can also enhance the character of the-this MUD area by providing
corridors for trails and wildlife, and for the protection of natural resources, riparian habitats and natural features
essential to the identity of the-this MUD area.
B. Land designated as having limiting site factors on the Southeast Weld Map
24XX, the most recent copy of which is on file at the Clerk to the Board's office and the Department of
Planning Services, are primarily defined by the one-hundred-year floodplain (as defined by FEMA Flood
Insurance Rate Maps) which comprises approximately 8 percent (%) of the total designated area in the-this
MUD area. Sites shown with limiting factors also incorporate other important natural features as well, including
wildlife habitat, mature riparian areas, primary drainageways and sand and gravel resources. Therefore,
additional land containing limiting site factors is shown along irrigation canals and ditches and adjacent to lakes.
To the maximum extent practical, development within areas having limiting site factors shall be located to
preserve the natural features of the site, to avoid areas of environmental sensitivity and to minimize negative
impacts and alteration of natural features.
Sec. 26-2-3-40.Comtnon open space regulations.
A. All Planned Unit Developments(PUDs) within the MUD area shall preserve a portion of the site as common
open space. Common open space is defined as any usable parcel of land or water essentially unimproved and set
aside, dedicated, designated or reserved for public or private use or enjoyment or for the use and enjoyment of
owners or occupants of land adjoining or neighboring such an area. Common open space includes landscape areas
that are not occupied by buildings or uses, such as storage or services areas, private courtyards, parking lots and
islands. In all PUD districts except for those containing residential uses, common open space may include
landscape setbacks adjacent to roadways, where the setbacks are not utilized as parking or storage areas. Common
open space is not to be included in the calculation of the maximum coverage per lot. The minimum percentages of ^' '
land in each development devoted to common open space is listed in Appendix 26-E to this Chapter. Department
of Planning Services' staff reserves the ability to evaluate development design proposals with less common open
space than listed in Appendix 26-E. The staff will determine if the proposed common open space meets the intent
14
of the requirements in this Chapter.
B. Common open space shall be delineated in the sketch plan phase of the PUD process. See the example at
Appendix 26-F. In areas preserved as common open space, a detailed description of the types of grass and
landscaping which will be utilized and the maintenance schedule for such landscaping shall be submitted to the
Department of Planning Services.
C. Cash-in-lieu of Common Open Space Regulation. In lieu of the preservation of land for on-site common
open space, and subject to the discretion of the Board of County Commissioners,the applicant may utilize the cash-
in-lieu of common open space option outlined in Section 27-6-80 B.8 with terms defined in Chapter 27, Article II
of this Code. This option shall be outlined in the sketch plan application to the Department of Planning Services.
(Weld County Code Ordinance 2001-1)
Sec. 26 2 3-50.Maximum lot coverage regulations.
All land use applications in the Southeast Weld MUD areas shall adhere to the regulations governing the
maximum percentage of lot coverage. The maximum lot coverage is defined as the maximum percent of the total
area of a lot in a zone district that shall be covered by any structure. Land shall not be deemed covered if it is used
for growing grass, shrubs, trees, plants or flowers it is covered by decorative gravels or wood chips, or if it is
otherwise suitably landscaped. The percentage of coverage on a lot shall not include the area of the lot or
development designated as common open space as outlined in Appendix 26-E. The percentages outlined in Table
26.2 below shall be deemed the maxinnm lot coverage for each zone district within the Southeast Weld MUD area.
Table 26.2
Maximum Lot Coverage in the Southeast Weld MUD area
Zone District within the Percent of Maximum
PUD District Lot Coverage
C-1,C-2 95%
R-1,Estate,A* 30%
R-2,R-3,R-4,R-5 60%
*Agricultural zone districts in platted areas.
Sec. 26-2-3-70.60 Landscaping regulations.
A. Intent. Landscaping is extremely important for ensuring the quality of development in the Southeast Weld
MUD area. Trees, shrubs and other plantings add greatly to the aesthetic appeal while controlling erosion,reducing
glare, lowering temperatures, buffering sounds and blocking or diverting wind. As no single landscaping plan can
be prescribed for all developments due to differing land features, topology and soils, the County allows flexibility
and encourages creativity in landscape designs. Landscaping must be sensitive to the characteristics and
maintenance requirements of the planting selected. Species must be chosen that are hardy for the climate and soil
conditions in the Southeast Weld MUD area, that can tolerate traffic, that are resistant to disease and insects, and
whose maintenance needs can be met. The following landscaping standards set mininvm requirements for all
developments within the MUD areas.
B. Design Criteria.
1. Landscapes shall utilize the following principles for maximum use of water: (a) well-planned and
approved planting schemes; (b) appropriate selection of drought-tolerant turf species to minimize water needs
and the use of water-hungry species of turf; (c)mulch to reduce evaporation;(d)zone plant groupings according
to their microclimatic needs and water requirements; (e)improvement of the soil with organic matter if needed;
(f) efficient irrigation design; and(g)proper maintenance and irrigation scheduling.
2. Landscapes shall consist of a variety of species. A partial list of plant materials that are native or adapted
to Colorado's Front Range is included in Appendix 26-G. Plant materials that are discouraged within this area
!"1 include:
a. Cotton-bearing cottonwoods(Populus).
b. Siberian and Chinese elm(litmus).
15
c. Tree of Heaven(Allianthus).
d. Russian olive(Eleagnus angustifolia).
e. Purple loosestrife(Lythrum salicaria).
f. All plants identified as noxious plants in Chapter 15 of the Weld County Code.
3. Buildings and parking areas shall be located to preserve and promote the health of existing trees. The
applicant shall be responsible for locating and preserving, where feasible, all individual trees of four-inch caliper
in size or larger, and massed groups of small trees. Before construction,the following precautions shall be taken
to preserve quality trees:
a. The applicant shall submit to the Department of Planning Services a detailed Landscape Plan
delineating the existing and proposed trees, shrubs,ground covers, natural features such as rock outcroppings
and other landscaping elements. The Plan shall show where landscaping exists or will be located, along with
planting and construction details. Where existing plantings are to be retained, the applicant shall include in
the plans proposed methods of protecting the plantings dhring construction.
b. The applicant shall demonstrate to the Department of Planning Services that the maximum possible
landscaping was preserved or relocated through the development process. At least 15% of the overall site
must be landscaped. See Appendix 26-F
c. Heavy equipment shall be kept at least five (5) feet from tree drip lines to prevent tree roots from
being damaged.
4. Whenever the use of the property to be developed or redeveloped will conflict with the use of adjoining
property, there shall be an opaque planted screen between the two(2) properties. The screen shall moderate the
impact of noise,light, aesthetic concerns and traffic.
5. All landscapes shall strive to maximize the use of native species. Where native material is not
appropriate for the intended use or appearance, plant species that are regionally adapted and noninvasive shall
be used.
6. Fescue, brome/fescue or other turf types shall be used in lieu of bluegrass where heavy foot traffic is not
anticipated. Seeding versus sodding of all turf types is preferred when the growing season allows for adequate
germination and establishment of the turf to sufficiently control erosion.
7. Landscape areas shall be configured to maximize their interconnectivity within the site, to natural areas
and to landscape areas within existing or future adjacent development. Small isolated islands of landscaping
except as required in parking lots and for screening along roadways shall be avoided. Open space shall be
provided where significant natural features exist.
C. Landscaping Requirements for Parking Lots.
1. At least ten percent (10%) of the area of a parking lot must be landscaped if the lot contains ten(10) or
more spaces. The requirement may be counted toward the maximum lot coverage requirement of each zone
district. At least seventy-five percent(75%)of the required landscape area shall include living plant material.
2. Berming and shrub or tree planting shall be used to screen parking lots from view of the roadway. Berms
can vary in height depending on location and proximity of existing trees. Berns shall have smooth transitions
from the top of the curb to the setback line so as to not create snow traps, with allowances made for placement
of the sidewalk. Grading of berms shall not be lumpy or abrupt. See Appendix 26-11 to this Chapter.
3. Landscaping techniques shall be used to alleviate the harsh visual appearance that accompanies parking
lots. See Appendix 26-I to this Chapter. At least seventy-five percent(75%)of the length of the frontage of the
parking lot must be effectively screened.
4. A minimum of five percent (5%) of the parking area shall be landscaped exclusive of setback areas.
Trees planted in parking areas should be either in bays or planting islands of at least five(5)feet by five(5)feet.
Trees should be distributed throughout the parking area, however, they shall be placed so that they do not
obstruct visibility for cars and pedestrians. Generally every tenth parking space should be delineated with a
planting island in addition to the 5%. See Appendix 26-J to this Chapter.
16
5. Loading, service or storage areas must be screened with an opaque screen that is an integral part of the
building architecture. Chain link fencing with slats, fabric or pallets are not an acceptable screening material.
Plant material shall be used to soften the appearance of the screen.
D. Landscaping Requirements along Roadway Corridors.
1. Intent. The major roadway corridors within the MUD areas are,County Road 22,County Road 49 and I-
76 and all strategic roadways delineated by Weld County Strategic Roadways, dated December 2004. The
major roadway corridors within the Southeast Weld corridor are Weld County Roads 49 and 22. These
roadways play an important role in the function and image of the MUD areas. The following design standards
relate to the visual quality of these four (4) roadways. As the MUD areas develop, additional roadways may
require similar consideration as these existing major roadway corridors. This determination will be made by the
Department of Public Works and the Colorado Department of Transportation. All roadways that are not
considered major roadway corridors are considered secondary roadways.
2. Design Criteria.
a. Plantings along road rights-of-way shall be integrated with the rest of the site.
b. That portion of a lot in any zone district which abuts a public or private road right-of-way shall be
landscaped with a minimum two-and-one-half-inch caliper shade tree or six-foot minimum height coniferous
tree at a distance of ten(10)feet,measured at a right angle from the lot line towards the interior of the lot, for
every forty (40) linear feet of street frontage. Trees may be grouped with a maximum distance of one
hundred(100)feet between trees or groupings, with exceptions made at entrance drives.
c. A minimum landscape setback along I 25, SH 119I-76, County Road 49 &County Road 22 and their
subsequent frontage roads shall be fifty(50)feet measured from the existing or planned future right-of-way.
d. Along 125, SII 119 I-76, County Road 49 & County Road 22, SH 66 and WCR 1, tree planting
distances shall be clustered or grouped from the roadway to avoid a straight line of trees. The effectiveness
of the screening shall be increased by planting trees and shrubs in layered beds (two [2] or more rows of
plant material rather than a single row). A mix of coniferous and deciduous trees and shrubs shall be planted
e"-1/4 in clusters or groupings.
e. Applicants adjacent to I 25 and/or SII 119 I-76, County Road 49 &County Road 22 shall construct a
berm along I 25 and/or SH 119I-76,County Road 49 &County Road 22 with maximum 5:1 side slopes to a
height sufficient to screen ground plane development (parking lots, storage areas or other similar site
elements) as far as one hundred eighty (180) feet from the right-of-way line (fifty [50] feet of landscape
setback plus one hundred thirty [130]feet of site development). The maximum height berm required shall be
six(6)feet above the existing elevation in the location of the berm. If needed, additional height beyond that
which can be achieved with a six-foot-high berm shall be achieved through dense landscape plantings.
Plantings on top of berms shall be designed so as to not create snow traps. A berm may not be required if the
subject property is elevated above the roadway and it can be demonstrated that views into the site will not be
possible for a distance of one hundred eighty (180) feet. Required landscaping and screening within the
landscape setback and other portions of the property shall be governed by the landscape standards contained
within this Chapter and any other more restrictive requirements contained in Chapters 23 and 24 of this
Code.
f. There shall be a minimum twenty-five-foot-wide landscape setback along SII 66 and WCR 1 SH 52,
WCR 22 and WCR 49 measured from the existing or planned future right-of-way.
g. There shall be a minimum twenty-foot-wide landscape setback measured from the existing or planned
future right-of-way to any parking lot, fencing, storage area or structure. Required landscaping and
screening within the landscape setback and other portions of the property shall be governed by the landscape
standards contained within this Chapter and any other more restrictive requirements contained in Chapters 23

{Public Works to provide input on this section]
Sec. 264-3-70 S0. Transportation and circulation regulations.
A. Intent. As transportation demands increase in the MUD areas, the need to preserve the functional integrity
and hierarchy of the existing roadways and provide new roadway capacity is becoming increasingly important. The
purpose of this Section is to provide for the planning, design and construction of improvements to new and existing
roadway facilities consistent with Chapters 22, 23, 24 and 27 of this Code. The intent of these standards is to
provide for a certain level of performance. Consequently, if it can be shown that an alternate design, material or
procedure will provide performance equal to or better than the required design, material or procedure, that alternate
may be approved by the Director of Public Works.
B. Traffic Impact Analysis. All significant developments within the MUD areas shall be required to prepare a
traffic impact analysis. All traffic analysis information and reports shall be prepared and certified to by a registered
professional engineer competent in traffic engineering. The intent of this analysis is to determine the project's
cumulative development impacts, appropriate project mitigation and improvements necessary to offset a specific
project's impacts. The County may require the developer to contribute for payment of the costs of said
improvements through an improvements agreement. All traffic impact analysis shall contain, as a minimum, the
following information:
1. Introduction: Describe the proposed development and parameters of the study area.
2. Existing Conditions:
a. The street capacity standard in the MUD areas is Level of Service C and the intersection capacity is
Level of Service D.
b. Conduct a.m. and p.m. peak hour turn movements and average daily traffic counts for intersections
and links within the study area if there are no available counts collected within the previous twelve (12)
months,
c. Conduct a peak hour intersection level of service analysis for the intersections.
d. Determine whether the existing daily traffic volumes exceed the arterial daily volume standards as
identified in the MUD street standards for major arterial, arterial, secondary, collector and local streets
presented in Appendix 24-E, Roadway Cross-Sections, to Chapter 24 of this Code. These standards
delineate right-of-way,lane configurations, median treatment,bike lanes and pedestrian sidewalks.
3. Cumulative Conditions:
a. Identify previously approved or anticipated developments that may affect the study area's circulation
system.
b. Generate, distribute and assign traffic to the existing roadway network.
c. Determine annual growth rates and project future traffic volumes for the time frame corresponding to
project build-out.
d. Identify funded circulation improvements,both public and private,that will be constructed prior to the
proposed development's occupancy.
e. Conduct a peak hour intersection level of service analysis and compare daily volume forecasts to street
standards assuming cumulative developments, annual growth rates and funded improvements.
f. Determine mitigation measures to offset cumulative conditions if level of service exceeds the MUD
areas standards.
4. Trip Generation: Determine daily and a.m. and p.m. peak hour trip generation for the proposed
development using established rates identified in the Trip Generation Manual published by the Institute of
Transportation Engineers or as agreed to with County staff.
5. Trip Distribution: Based on assumptions contained in the MUD areas traffic analysis or market
estimates,describe the anticipated trip distribution patterns for the proposed development.
18
6. Trip Assignment: Based on the projected trip generation, assumed trip distribution and the prevailing
roadway network, assign the projected traffic to the intersections and streets within the study area.
7. Existing+Committed+ Project(E+C+P)Traffic Volumes and Level of Service:
a. Add project a.m. and p.m. peak hour and daily traffic volumes to existing plus committed traffic
volumes.
b. Conduct intersection level of service analysis and determine whether daily traffic volumes exceed
street standard thresholds.
8. Signal Warrant Analysis:
a. The I-25 MUD Transportation Network Map 2.2, the most recent copy of which is on file at the Clerk
to the Board's office and the Department of Planning Services identifies future locations for signalization;
signals,however, should not be installed prior to when they are needed.
b. Using the AASHTO Manual on Uniform Traffic Control Devices (MUTCD), determine whether
proposed intersection volumes exceed signal warrants for those locations on the transportation network
where signals are proposed.
9. Access: Projects involving access to the state highway system shall indicate appropriate conformance to
the latest revisions of the State Highway Access Code. The report shall discuss how the proposed development
meets the access control guidelines as presented in Section 4.4.2 of the MUD Background Document, available
at the Department of Planning Services.
10. Mitigation Measures: Mitigation measures will be to implement the needed improvements to offset
project impacts as determined by the traffic impact analysis.
C. Design Standards.
1. All development within the MUD areas shall comply with Chapters 22, 23, 24 and 27 of this Code and
the Colorado State Highway Access Code, 2 CCR 601-1. Consistent with the urban-scale development
standards in the MUD areas, all parking areas for commercial and industrial development shall be paved
according to geometric and road structure design standards.
2. Geometric Design Standards. Geometric design for streets and roads shall be in accordance with A
Policy on the Geometric Design of Highways and Streets published by the American Association of State
Highway and Transportation Officials. Specifications, standards or design criteria published by the other
governmental agencies, professional organizations or generally accepted authoritative source may be used in
geometric design. All specifications, standards, or design criteria shall be referenced and copied as part of the
submittal information.
3. Road Structure. Structural capacity shall be designed in accordance with the Guide for Design of
Pavement Structures published by the American Association of State Highway and Transportation Officials.
Specifications, standards or design criteria published by other governmental agencies, professional organizations
or generally accepted authoritative source may be used in design. All specifications, standards or design criteria
shall be referenced and copied as part of the submittal information. All roads shall adhere to the standards set
forth in Chapter 24,Article VII of this Code.
4. Structural Road Improvements. Adjacent roadways shall be designed to meet the full typical section
specified in the County Transportation Plan and Chapter 24 of this Code. Improvements may include the
construction of travel lanes, shoulders, bike lanes, medians, curb, gutter and sidewalks, for example. Required
improvements may also include the acquisition of right-of-way and construction easements that will be
dedicated to the public. Improvements attributed to the development shall be consistent with the direct impact a
particular development has on the County road system, as determined by a professional transportation study.
The road improvements agreement and roadway construction plans shall be considered by the Board of County
Commissioners.
D. Circulation System.
1. The proposed MUD circulation system is presented at Map 2.2, the most recent copy of which is on file
at the Clerk to the Board's office and the Department of Planning Services. The transportation networklg
reflects a hierarchy of roads, from a major arterial which serves both the regional and local traffic with higher
speeds and capacities with controlled private access,to a collector which serves local traffic and provides access
to future development. The proposed hierarchy of roads includes both reconstruction and/or widening of
existing roads and alignments for new roads. The transportation network also identifies locations of future
signals.
2. The MUD roadway cross-sections are identified at Appendix 24-E, Roadway Cross-Sections,to Chapter
24 of this Code. Roadway classifications may change as development in the MUD areas occurs. Roadway
classifications may be re-evaluated by the Director of Public Works with the results of the traffic impact
analysis. (Weld County Codification Ordinance 2000-1; Weld County Code Ordinance 2001-1)
Sec. 264-3-80 Sign district regulations.
A. Intent. Within the MUD areas,signage has become an increasing issue, especially along traffic
corridors such as I-25,SH 119 and Weld County Roads 22 and 49. While signs serve as important
directional,informational and advertising tools,the clustering of signs may obscure the landscape
and confuse and distract drivers. Signage con are intended to protect and preserve the visual
quality of the roadways within the MUD areas while preventing the obstruction of traffic visibility
and confusion from improperly placed and designed signs. These provisions control the magnitude,
placement and number of signs in the MUD areas. These regulations can be found in Section XX-
x-XX of this Code
Sec. 26-2-3-90 400. Utility,infrastructure and public facility regulations.
A. Intent. By their nature, most utility services are highly regulated. This regulation encompasses ownership,
financing, competition, cost recovery, construction, environmental protection and safety. Given this regulatory and
legal environment, well-established federal, state, county and industry standards/codes exist that govern most
aspects of utility service. The intent of this Section is to provide additional regulations and standards for water
supply to meet fire flow demands and solid waste collection service, and to provide standards for public facilities
and services throughout the MUD areas. ^�
B. Water Supply and Sewage Disposal. The specifications of water supply requirements for fire protection
within the MUD areas is provided by the Mountain View Fire Protection District. The Mountain View Fire
all be consulted concerning the fire district's fire requirements. Chapter 22 of this Code
specifies that the water supply system serving a proposed development site or zone district must deliver a minimum
of five hundred (500) gallons per minute at twenty (20) pounds per square inch residual pressures for thirty (30)
minutes. Pioneer Metropolitan District shall provide for the sewage disposal within the Southeast Weld MUD areas
except those uses specifically called out and exempted from the PUD process in Section 26-2-60 of this Chapter.
C. Solid Waste. Residential and commercial solid waste collection services in the area shall be arranged
directly between solid waste disposal firms and property owners/managers. Solid waste disposal shall be
accomplished by collection firms at licensed disposal facilities.
D. Storm Drainage Design and Technical Criteria. The County does not publish technical data or storm
drainage design manuals. The consulting engineer for the developer is to use published material by a generally
accepted authority approved by the Director of Public Works. The material used must be referenced and copied as
part of the submittal information. All development within the MUD areas shall adhere to the Storm Drainage
Design and Technical Criteria regulations in Section 24-7-130 of this Code.
E. Schools.
1. A residential subdivision application shall be referred to the applicable school district for review
and recommendation regarding school district requirements. The Department of Planning Services, Planning
Commission and Board of County Commissioners shall consider the recommendation of the school district.
