Project Overview

Independence is a diverse master-planned community located in Elbert County, Colorado. The

preservation and conservation of what makes Independence a special place will create wide-open

spaces and only-in-Colorado views.

The site consists of gently rolling hills and swales that range from pine oak woodlands to foothill

grasslands. Land use in the region is typified by woodland and rangeland that is increasingly being

developed for residential use. There are several wetland areas scattered throughout the property as

well as multiple unnamed tributaries of Cool Creek and Henderson Gulch.

The topographic and geologic features on-site create a range of growing conditions to a variety of

native plant materials. Largely, the existing site can be described as a transitional zone of short grass

prairie and Gamble oak woodlands that have been disturbed by agricultural activity, principally, cattle

ranching.

In keeping with Independence’s intention for authenticity, the landscape concept retains the site’s

unique natural features, adding essential enhancements that respond to the land. The landscape sets

the tone for the community, and reinforces its identity. Development within the site will primarily

consist of single-family residences, yet over forty percent of the land area will be preserved as open

space — further supporting the developer’s commitment to character and the native environment.

Key Community Objectives

• Create a best-in-class, yet attainable, self-sufficient and inclusive community.

• Maintain the natural landscape and agrarian ambiance.

• Establish a sense of safe, diverse, and open community among the neighbors.

• Promote physical and social health.

• Promote environmental and agricultural sustainability.

• Create a suburban destination.

• Maintain an open habitat corridor.

Purpose and Organization of this Document

The purpose of these standards is to create excellent and well-defined landscapes within the

Independence community. The standards are organized into three sections: Introduction, Community

Standards & Guidelines, and Residential Standards & Guidelines. The Community Standards &

Guidelines are organized by the different major features of the community and describe the specific

and quantifiable site planning requirements that will be applied consistently across the entire 1,000-

acre site. The Residential Standards & Guidelines are organized by the different features on a residential

lot and describe the specific and quantifiable requirements that will be applied consistently on each

lot.

Hierarchy of Information

This document uses the following hierarchy to convey its requirements and recommendations:

• Intent

• Guidelines

• Standards

Intent - describes the primary design or functional objective for the stated topic, based on the vision

of the community.

INTRODUCTIONStandards - the required components of the designs for development. The Standards are the requirements

that must be met. Any variance from these standards must be requested from and approved by the

appropriate regulator, in this case, the Independence Design Review Board (DRB.)

Guidelines - include design strategies, features, or techniques that the Independence DRB is encouraging.

In cases where the guidelines may be difficult to achieve, or an innovative solution may provide a better

answer, the guidelines can be waived by express approval of the Design Review Board if the Applicant can

demonstrate that the topic’s stated Intent has been achieved.

How to Use this Document

The Independence Design Standards serve as a guide for the future development of streetscapes,

pedestrian corridors, parks, open space, residences and corresponding landscape improvements

throughout the Independence community. These standards are intended to clarify approach, intent, and

general character of the community and strive to illustrate a level of finish and materiality appropriate for

these places.

The Design Standards shall be used in the following 3 step process:

• Step 1 - Determine appropriate Standards Zone. Determine the relevant use zone for the project

area; reference the Standards Zone Diagram on page 11.

• Step 2 - Consider criteria and develop design possibilities based on Intent in the Community or

Residential Standards & Guidelines sections. Following programmatic and design criteria outlined in

the Design Standards, develop appropriate design responses. Reference the conceptual approaches

for each use zone illustrating a sampling of design possibilities. Ensure that designs meet the

Standards. Show how designs meet the Guidelines, or how the design meets the Intent.

• Step 3 - Select appropriate materials utilizing the standards and guidelines for each section.

Examples and listings of recommended materials are outlined in each section.

• Note: If the standards and guidelines cannot be met, schedule a review with the Independence

Design Review Board to request a variance.

Administration of Standards / Design Review Process

Design review is required for any development or renovation within the community area. The DRB will

review all submittals for conformance with the spirit and intent of the Design Standards.

The design review process is meant to ensure that the Design Standards are applied to all property within

the Independence community. A series of plan submissions to the DRB will be required at different stages

of the design process. Reasonable fees will be charged for the pre-application meeting and all formal

submittals. A current fee schedule is available from the DRB upon request. Formal submittals shall be

made by the party responsible for the development or redevelopment of the property concerned. That

party shall be the Applicant and shall remain consistent throughout the approval process.

NATIVE ECOLOGY

With over 200 vertical feet of change across the site,

distinct plant communities can be found throughout

the property. Dominant vegetation consists of noxious

and non-noxious weedy species, likely an effect of prior

ground disturbance due to agricultural development.

Noxious weed species include Canada thistle, bull thistle,

musk thistle, diffuse knapweed, common mullein, and

downy brome. Native plant species consist of yellow

sweet clover, curly dock, Jim Hill mustard, fringed sage,

yellowspine thistle, soapweed yucca, orchard grass,

locoweed, and fescues. Tree species observed in the area

include narrowleaf cottonwood, New Mexican locust, and

ponderosa pine.

The foundation of the landscape concept is based on

existing topography — specifically, three landscape

typologies that consist of both overlapping and unique

plant materials:

UPLAND ECOLOGY occurs across the majority of the

site and consists of open short-grass prairie. Examples

of ‘Upland’ native plants in the region include soapweed

yucca, orchard grass, locoweed, and fescues punctuated

by Gambel oak, Ponderosa pine, and New Mexican locust.

HILLSIDE ECOLOGY is defined by a sparse covering of

shrubs and grasses in the steeper areas, particularly along

south-facing slopes. In this transition between arid/higher

and fertile/lower areas, the Gambel oak is the primary

species of size. Other ‘Hillside’ plants in the region include

ponderosa pine, serviceberry, mountain muhly, and blue

grama grass.

RIPARIAN ECOLOGY occurs in the lowest areas near

active drainages, dry creek beds, and ephemeral ponds

where soils tend to be more fertile and moist. Narrowleaf

Cottonwood is the dominant tree in this category -

sandbar and peach-leaved willows can also be found.

Shrubs tend to grow in groves and thickets, and include

wild plum, hawthorn, currant, wild rose and shrubby

willow. Grasses may include saltgrass, prairie dropseed,

and western wheatgrass, along with sedges and rushes

clustered in the damp soil.

APPLIED ECOLOGY SYSTEMS PLANUpland

APPLIED ECOLOGY

The three site ecologies have been mapped and

documented on the Ecology Systems Plan. An ecologies

overlay was created with the primary study area

development plan to determine planting opportunities

and constraints. The ecologies were modified as little as

possible to accommodate planting in unique or difficult

areas, such as along roadways, steep slopes, and in

residential neighborhoods. The resulting Applied Ecology

Systems Plan became vital to the overall landscape

concept strategy.

The site as it exists is beautifully emblematic of the

region, and a significant part of the developer’s vision.

The current desirable plant materials are intended to be

preserved or enhanced wherever possible. Future roads,

for example, are planned to be designed and built in a

manner that minimizes disturbance and grading of the

site. The character of existing desirable plant material will

be replicated throughout the development, strategically

using both natives and appropriate ornamentals that

are fitting for each ecology zone and site location. The

approved plant materials can be referenced in Section 4:

Plant Materials.

In addition to the three naturally occurring ecology zones,

a fourth ecology was added to accommodate residential

builder and homeowner needs. The ornamental ecology

zone overlaps with ‘Upland’ and ‘Hillside’ ecology areas

and includes non-native, decorative plants to be blended

with roughly thirty percent native grasses, perennials and

shrubs. Ornamental plants can also be used tactically

within other site ecology zones as an accent at key

locations such as community and neighborhood entries.

The four applied ecology zones are location dependent;

therefore ecological typologies can differ across similar

program areas. The various community entries, for

example, will feature a diverse range of plant species and

aesthetics, as entries occur within different ecological

zones on site.

COMMUNITY STANDARDS AND GUIDELINES

Description

The Community section of the Landscape Design

Standards and Guidelines summarizes the

essence, goals, and aspirations for the community

elements of Independence. The chapter includes

requirements for landscape design of the

Boulevard / Parkway, entries, parks, open spaces

and trails in the community.

The community elements included in these

design standards and guidelines consist of the

outdoor spaces that are not part of a building,

but are accessed by the public on a daily basis,

either visually or physically. The Independence

standards and guidelines are written to achieve

a high quality public realm. The goal is to assure

that the community’s public realm provides a

variety of rich outdoor experiences, compliments

the adjoining buildings and provides residents and

visitors a range of amenities that are unmatched

for new development. Some of the key elements

of the public realm at Independence include:

STREETS AND ENTRIES

The streets at Independence play a critical role

in creating a well connected, pedestrian friendly

community. Entries will signify community

character as well as provide effective wayfinding.

PARKS

Independence has a wide variety of parks,

gardens and plazas that create places for

gathering, play and respite throughout the

community. Ranging from the Homestead Park to

smaller 1,000 sq. ft.one to one-acre neighborhood

pocket parks, these spaces will become the hub

of public life for individual neighborhoods and the

community at large.

OPEN SPACE AND TRAILS NETWORK

Independence is surrounded by Colorado open

space that will be easily accessible via a series of

trail networks.

Guiding Principals

• The landscape design of the Independence

Community can be bold, creative and

compelling without being overly intricate and

complex. A single concept, executed with

bold, straightforward gestures can create

inspiring places that are easier to maintain

and will stand the test of time.

• Streetscapes and parks can support

community goals and provide clues to users

about priorities and intent. Using design

to create a clear hierarchy of streetscapes

and parks will help establish clear public

and residential domains, protecting

neighborhoods from unnecessary impacts

and focusing activity in community spaces.

• Landscape and public spaces are most

valued when serving multiple purposes. At

Independence, some parks use stormwater to

create interesting places, and the landscape

along streets is used to clean runoff. Rather

than designing spaces for one function,

public spaces designed to accommodate

many uses will generate more activity and

support a diverse community.

• All of the social, functional and aesthetic

goals of Independence can be enhanced

while conserving resources, energy and

water.

BOULEVARD / PARKWAY

Description

A Boulevard / Parkway will be used to access

the residential areas. It will be a two-lane road

and follow the county standards for a rural

major collector with a speed limit of 40 MPH.

The Boulevard / Parkway will have no curb and

will have a gravel shoulder. In order to create

a recognizable framework that effectively

strengthens community identity, plant types will

be identified by ecology zone and tend to be

larger-sized to create an aesthetically pleasing

look at faster speeds. Plantings are intended

to cross from one side to the other in drifts,

mimicking the existing landscape patterns. Where

roads cross existing drainages they will be held

to the narrowest possible road section in order to

allow the landscape character to effectively carry

across the roadway. A walking / biking trail will

run adjacent to the boulevard.

Intent

The primary purpose of the Boulevard / Parkway

is to facilitate vehicular circulation at a community

scale.

OPEN SPACEOPEN SPACE DRAINAGE CORRIDOR

RESTORED PRAIRIE

Description

Drainage Corridors occur within Open Space

zones but have unique landscape requirements.

Each corridor is 50 feet wide and centered on the

lowest elevations of the drainage channel itself.

Plant materials are different here than in most

other areas on site because of higher moisture

content and sandy soils. Cottonwood trees are

symbolic of this zone.

Intent

Natural Open Space Drainage Corridors serve to

convey stormwater and provide visual interest

on the site, as well as a habitat for wildlife in the

community.

Standards

• Drainage Corridors shall be preserved in their

natural state where possible, and minimally

enhanced to improve erosion control and

aesthetic quality.

• One hundred percent of the Open Space

Drainage areas shall be undisturbed open

space, with restored native seed and

wildflowers in areas of disturbance due to

drainage structure construction.

• No shrub or perennial beds are planned

within the Open Space Drainage area, except

near the well and sewer facilities.

• No permanent irrigation will be provided

within the Open Space Drainage areas.

Temporary irrigation shall be provided by

water truck or other temporary method for

trees that are planted within Open Space

BUFFER / SCREENING LANDSCAPE

Description

Restored Prairie areas will be reclaimed and

enhanced as existing open space and occur

in areas of disturbance due to construction or

grading activities.

Intent

There will be an effort in the Independence

community to return land that has been

disturbed by construction and agriculture and

return it back to the native ecosystem.

Standards

• The restoration activity will be multi-phased.

The first phase shall be initial revegetation for

overlot grading and roadway construction

with a final restoration that consists of

approximately 50% of the vegetation

replaced or overseeded with native seed,

primarily in high-visibility or heavily disturbed

areas.

• No Trees, shrubs, or perennial beds are

planned within the restored prairie area.

Guidelines

• Ten percent of the restored native seed

areas should be irrigated, primarily against

developed edges.

Description

Buffer and Screening areas will be primarily

around the water resource and recovery plant.

Intent

The purpose of Buffer and Screening areas is to

separate different types of land uses from one

another and to screen particular areas from view.

Standards

• One hundred percent of the Buffer /

Screening Landscape areas shall be native

seed.

• No shrub or perennial beds are planned

within the Buffer / Screening Landscape

areas.

Guidelines

• If desired, there may be 10 trees per acre,

including both deciduous (50%) and

evergreen (50%).

• If included, trees should be organized in

informal groupings that shall sufficiently

screen areas as needed.

• Ten percent of the native seed areas should

be irrigated, primarily against developed and

highly visible edges.

UNDISTURBED OPEN SPACE

Description

Undisturbed Open Space areas occur around

and throughout the entire community. Multi-use

and single track trails will be primarily within this

zone.

Intent

This open space zone type is intended to be

left as is, with minimal disturbance by trail

construction.

Standards

• Undisturbed Open Space areas are to be

preserved in their natural state as much as

possible.

• Plant materials shall consist of what is already

pre-existing in this zone.

• No trees are planned within the natural areas.

• Non-irrigated native seed shall be

concentrated in disturbed areas along trails.

REAR LOT TRANSITION

Description

Rear Lot Transitions occur behind and alongside

residential lots where no other lot or predominant

landscape zone exists. Similar to roadway

transitions, Rear Lot Transitions often link the

more finished residential landscape with more

native open space.

Intent

The purpose of Rear Lot Transition zones is to

provide a gradual transition from development

lots to natural open space areas.

Standards

• Trees will only be located in areas visible from

the Boulevard and Community Entries.

• One hundred percent of the Rear Lot

Transition areas shall be native seed. No

shrub and perennial beds are planned within

the rear lot transition areas.

• Thirty-three percent of the native seed areas

shall be irrigated, primarily against developed

edges and in areas of high visibility from the

Boulevard / Parkway and Community Entries.

Guidelines

• The Rear Lot Transition zone should be 25

feet wide, but may vary depending upon

location.

Drainage areas at a sufficient quantity and

schedule until the trees become established.

• Any tree that is disturbed or removed due

to construction in the Open Space Drainage

Area shall be replaced with same or similar

species. There shall not be a minimum

quantity of trees per acre.

TRAILS

25June 5, 2017 June 5, 2017

Description

An important part of enjoying the Colorado

lifestyle is living outdoors. The Independence

community will include a trail network for its

residents and visitors. Independence will have

approximately 5-10 miles of trails circulating

around and through the community. There

will be two types of trails in the Independence

community:

• Multi-Use Trails will be used as connectors

to get to a neighbor’s house, a park or a

community amenity. These will have a wider

surface where two people can walk side by

side or someone can walk with a stroller.

These multi-use trails are the main trails and

are therefore wider and more usable.

• Single Track Trails are recreational trails that

people can use to walk dogs, run or ride

bikes. These will be a narrower width.

Intent

• The purpose of the trails network is to

provide outdoor pathways for residents

and visitors to walk, run, bike, and enjoy the

outdoors, as well as to connect to amenities

and other areas throughout the community.

Standards

• Multi-use trails shall be located adjacent to

the Boulevard / Parkway and shall be four to

eight feet wide.

• Multi-use trails shall be constructed with a

minimum of four inches of deep decomposed

granite surfacing or approved equal.

RESIDENTIALACCESS AND CONNECTIVITY

Intent

The Independence Community should have a

vehicular and pedestrian network that are safe

and connected, and provide ease of access

to neighborhoods and community amenities.

Neighborhood entries should be visible from the

streets to facilitate wayfinding and ease of access.

Pedestrian movement should be made easy

throughout the neighborhood through the use of

trails.

Independence is a well-connected community.

The goal of these standards is to ensure that, in

addition to the arterial and collector roads that are

delineated in the Community Plan, smaller, local

streets create an interconnected network through

all of the neighborhoods.

Standards

• All primary access points shall be provided as

described in the Community Plan.

• All streets shall be available for public use and

not gated.

• All cul-de-sacs shall include pedestrian or

bicycle through connections.

Guidelines

• Trails should connect the neighborhoods to

the adjacent Pocket Park, the Homestead Park

and the Open Space.

• All secondary access points are optional.

LOT LAYOUT

Intent

In general, there are three lot types for single-

family detached homes, each in response to

varying styles, household size, and density. Lots

are generally found in the following ranges relative

to street frontage:

• Alternative Standard Lots - 50’ to 60’ width

with an overall area of less than 7,000 sf.

• Standard Lots - 70’ to 80’ width with an overall

area between 7,000 sf and 10,000 sf.

• Estate Residential Lot - 81’ or greater width,

with an overall lot area exceeding 20,000 sf.

Standards

• Lot setbacks shall conform with approved

standards set forth by the PUD documents.

FRONTAGES / ENTRANCES

Intent

Well-articulated entries visible from the street

contribute to neighborhood character and help

promote a sense of community. Doors and

entries in proportion to the scale of the building

and compatible with the architectural expression

are important neighborhood design elements. In

addition, the entrance should create a gracious

transition from outside to inside, providing shelter

from the weather and shielding at night.

Front porches play an important role in establishing

a sense of community within a neighborhood.

Setbacks as well as the size of the porch or

covered entry vary depending on the lot type and

size of home. A setback range is provided to allow

for some variation and design freedom in how the

porch and building are integrated.

Standards

• The primary entrance shall be visible from the

street.

• The primary entrance shall have a covered

entry area with placement and a minimum size

in accordance with lot type.

Guidelines

• The primary entrance should be in proportion

and character to the front elevation of the

principal building.

• Front porches and entrance areas should be

kept free of clutter and be well-maintained.

Description

This section of the Landscape Design Standards

and Guidelines summarizes the essence of design

elements, product goals, and neighborhood

aspirations for the residential neighborhoods of

Independence. The chapter includes requirements

for landscape design, which has a significant

impact on the community’s appearance, livability,

and sustainability.

Organized amidst vast open space and within

walking distance of the Homestead Park, The

Neighborhoods at Independence will become a

series of interconnected places that offer a variety

of living options for residents. Homes will face and

define a network of residential streets and small

pocket parks that will become the centerpiece of

each neighborhood.

Guiding Principles

• Create neighborhood consistency, without

constraining design innovation.

• Foster diversity of architectural character,

with a high degree of mixed products on block

faces.

• Establish a clear and understandable

neighborhood organization where buildings

actively shape the character and quality of the

public realm.

• Achieve authenticity, simplicity, and

consistency without imposing stylistic

solutions.

• Create connections between neighborhoods

and their surroundings, while balancing the

need for hierarchy and identity.

• Balance high quality design and construction

with economic feasibility.

• Implement and continually advance

the practice of sustainable building and

development.

Refer to the following pages for specific

requirements and representative landscape plans.

EXTERIOR LIGHTING

Intent

The role of a well-designed Exterior Lighting

system is to provide adequate light for safety

and wayfinding and subtly enhance building

and neighborhood character while preserving

the darkness of the night sky and reducing light

pollution and glare. The Exterior Lighting goal at

Independence is to find the right balancing point

between these objectives.

Standards

• Residential lighting shall be subject to DRB

approval.

• Light fixtures shall have full cut-off, dark-

sky compliant louvers or shields to reduce

upward glare.

• Exterior landscape lighting shall be low-level,

accent lighting.

• Each residence shall have a well-lit front

porch.

• House number shall be lit and easily visible

from the street.

• LED lamps shall be used in all exterior light

fixtures.

• Light color temperature shall range from

2700 to 3000 Kelvin.

• Flood lighting of yards, alleys, driveways, and

walkways is not permitted.

• Materials shall be durable, natural patina

metals consistent with colors and schemes

found throughout the Independence

community.

29June 5, 2017 June 5, 2017

GENERAL PLANTING

Intent

The purpose of the General Planting standards

is to ensure a cohesive, aesthetically-pleasing

appearance and plant palette for residential lots.

Standards

• Each home shall have an average of 500 sf of

irrigated landscape in the front yard of the lot.

• Areas that are not plant materials shall consist

of inorganic mulch.

• Each lot shall have between 1,000 and 3,000

square feet of irrigated lower-water use lawn in

the back yard based on the lot size as follows:

� 50-60’ Lots: 1,000 sf min / 2,000 sf max

� 70-80’ Lots: 1,500 sf min / 2,500 sf max

� 90’ Lots: 2,000 sf min / 3,000 sf max

• 50-60’ lots shall have a minimum of one tree

in the front yard and one tree in the back yard.

• 70-80’ lots shall have at least one tree in the

front yard and two trees in the back yard.

• 81’+ lots shall have at least two trees in the

front yard and two trees in the back yard.

• Foundation plantings shall be incorporated

around residences.

• Landscaping shall be maintained in the manner

and degree necessary to keep plants healthy

and presentable, including pruning, mowing,

weeding, fertilizing, watering, and replacement

of plant material, when necessary.

Guidelines

• Turfgrass / lawn may be placed in the front

yard of residential lots if desired as long as it

stays within the maximum irrigated turf limit

for the entire lot.

RESIDENTIALIRRIGATION

Intent

Being that water is a limited resource in our region,

the intent of the irrigation standards is to keep

plants healthy and aesthetically pleasing, while

reducing overall water consumption.

Standards

• Each residence shall have a maximum irrigated

turf lawn area ranging from 1,000 to 3,000

square feet. Refer to Table 3 on page 32

for additional information regarding specific

requirements for each lot size.

• Drip irrigation shall be used for all shrubs,

perennials, groundcovers and trees.

• Overhead spray irrigation shall only be used

for turf lawn areas.

• Permanent, automatic irrigation is required

for all planting areas and turf including raised

planters and containers.

Guidelines

• Low water use irrigation systems, such as

low precipitation and drip systems, can

significantly reduce water use. In addition,

irrigation sensors, which supply controllers

with information about the environment,

can monitor soil moisture, rain, wind, and

evapotranspiration in order to provide the

precise amount of water needed to keep

plants healthy.

• All irrigation systems should be designed to

minimize water use, and should utilize low

precipitation heads, drip systems, and other

low gallon heads as appropriate.

• All irrigation systems should include one of

the following system controls:

• Soil moisture or rain sensor

• Evapotranspiration (ET) controllers

that allow flexible programming to

adjust watering schedules to the

historical needs of plant types

• Evapotranspiration (ET) device

featuring ‘real-time’ feedback.

Intent

All Plant Material in the residential area of

Independence shall be native or xeric species

wherever possible. Each residential project or lot

must have sufficient landscape to create a quality

public realm.

Standards

• No less than 90% of all plant materials used

to landscape each site shall be selected from

the low water use zone found in the Colorado

State University Cooperative Extension Fact

Sheets on Xeriscaping, or other approved

xeriscape plant material reference.

• Plant materials shall be installed at the

minimum sizes described in Table 1.

• Plant coverage shall be calculated according

to Table 2.

• Table 3 describes the minimum planting

requirements for each residential development

type. Side yards facing streets shall meet the

requirements of front yards.

a minimum of 50% of all plant beds and raised

planters.

• Planting beds should be a minimum of 6 feet

wide.

• Landscaping shall be designed based on a

water budget with a maximum of 15 gal/sf/yr

when fully established, in addition to natural

precipitation.

• Plant palette shall take into account wildlife-

resistant materials.

• Plants shall be drought-tolerant species.

PLANT MATERIAL IRRIGATION (CONTINUED)PLANT MATERIAL (CONTINUED)

• Plant types shall match the planting types in

the Plant Materials section of these standards

(Page 35.)

Guidelines

• Front yard landscape design should clearly

delineate individual single family residences.

• Planting plans should consider horizontal

and vertical layering of overhead, eye-level

and ground plane (trees, shrubs and ground

covers) in order to define space and add

character.

• Shrubs and ground covers should be grouped

in beds at the base of the building or porch,

and/or along the entry walk.

• Low spreading ground covers should be

placed in the foreground.

• Trees, shrubs, and ground covers should be

planted in masses in order to define outdoor

spaces and reinforce entries and building

design.

• Massing plants of one species is encouraged,

particularly along fences.

• Planting schemes should consider seasonal

changes in foliage, color and texture in order

to create interest throughout the year.
