Design
and Visual Resources
"Subdivisions should be
designed as if conservation matters."
--Randall Arendt
Vision: Design development
to complement the environment, existing neighborhoods, and the historic
nature of the County.
Introduction The quality of life enjoyed by Summit County residents can in many ways be attributed
to our amazing natural mountain setting. As growth continues to occur
in the County, the type of development that occurs can have a direct impact
on our quality of life. Appropriately placed and designed buildings can
complement the natural environment and essentially serve as extension
to the natural landscape. However, inappropriately designed development
can detract from the area’s overall character. It is the goal of this
element to encourage types of development design that fit with the natural
landscape. It is not the intent of this element to dictate to minute
detail the type of design that should be used. In fact, there are many
types of architectural and site design styles that can complement our
surroundings.
The County is blessed with many highly scenic visual resources. High mountain
peaks are the most obvious of these visual resources, but they also include
many other features such as open meadows, riparian corridors, wetland
areas and forested areas. Development will inevitably occur within some
of these areas. However, the way that development is placed in these
areas can have a profound effect on the visual landscape. For example,
tucking residential homesites into trees at the edge of a meadow can preserve
the view of the meadow. Keeping building heights below the forest canopy
and using materials that blend with the forest can help maintain the visual
dominance of the forest. This element attempts to guide the appropriate
placement of development so that the natural landscape continues to be
the dominant view.
When one reviews the policies of this Plan, the emphasis on avoiding impacts
to open meadows, environmentally sensitive areas, forested areas, etc.
may beg the question of what locations are appropriate for development.
The intent of this element is to focus development in areas where it is
screened. Thus, forested areas are looked upon as a favorable location
for development, provided development is located in a manner that protects
the overall visual character of the forest and avoids adverse environmental
impacts.
Countywide
Design Program
Recognizing the importance of good design in future development, the County
embarked in 2000 on a process to develop design standards and guidelines.
A prominent consultant was hired to lead the effort, and a Countywide
Design Advisory Group was formed. By the end of 2001 the Group had reached
consensus on draft design standards and guidelines which the County should
use in future development review. None of these standards and guidelines
have yet been adopted by the County, although a number of the proposed
standards are being packaged into an amendment to the Land Use and Development
Code expected to occur in 2003. When fully implemented, these standards
and guidelines will provide further guidance for the character of development
in the County. Some of the policies in this element are based on recommendations
from the draft standards and guidelines.
Green Design
Buildings
have a tremendous impact on the environment--both during construction
and through their operation. Considering ways to reduce the pressures
or impacts resulting from new construction and existing structures can
help protect our environment. A pragmatic means to address this is through
incorporating green standards into new developments and remodels. Green
standards refer to building design, construction strategies and maintenance
techniques that reduce environmental impacts by incorporating energy efficiency,
water conservation, water minimization, pollution prevention, resource-efficient
materials and indoor environmental quality in all phases of a building’s
life.
In
simple terms the concept of 'green' design means to design, construct
and maintain a building in such a way that it will minimize impacts on
its environment throughout its life. Green built structures aim to incorporate
resource conservation techniques. There are many benefits that stem from
homes built to more stringent energy, water, and resource-efficiency standards.
Some of these benefits include reduced energy consumption, protection
of ecosystems and improved occupant health. Promoting green buildings
helps achieve sustainable and efficient use of resources in design, use
of materials, siting and land use.
There are many aspects
of green design for designers and builders to consider. Deciding which
measures are most important is not easy as green design priorities change,
can be subjective and driven by local, state or federal incentives. The
following lists some of the environmental values of green design:
·
Minimizes impacts to the
environment.
·
Promotes environmentally
responsible practices in construction.
·
Conserves and safeguards
water and energy.
·
Reduces material use and
selects low-impact materials.
·
Provides greater efficiency
and maximizes longevity.
·
Reduces resource depletion
and pollution.
·
Protects indoor air quality.
·
Improves site planning.
The BigHorn Improvement
Center in the Town of Silverthorne is an example of a locally green built
structure that incorporates green design concepts and eco-friendly amenities.
The Center has won awards for sustainability as it incorporates and uses
recycled materials and energy-saving methods (e.g., clerestroy windows,
skylights, photovolataics and solar walls). A green design program available
through the County’s Building Department was E-Star (Energy Rated Homes
of Colorado). The program was available to developers and contractors
for approximately 10-years and was never utilized. The discontinued program
offered discounts to building permit fees for constructing to a minimum
level of energy efficiency and using ecologically friendly materials.
Goals, Policies/Actions
Goal A.
Visually important lands should be preserved and the rural mountain landscapes
of the County should be maintained.
Policy/Action 1. Basin master plans should identify
and prioritize visually important lands. The following criteria
should be used when identifying these lands:
1.1 Lands
that provide visual separation between communities.
1.2 Lands that are visually
prominent (e.g., hillsides, open meadows) as viewed from key public
places (e.g., major arterials and highways, parks and public open space
areas).
Policy/Action 2. Work with the towns and other
appropriate entities (e.g., U.S. Forest Service) to provide visual
open space buffers around communities to maintain separation between
communities and to emphasize the uniqueness of each community.
Policy/Action 3. Keep lands of highest visual
importance (as identified in basin master plans) as free as possible
from visual impacts of buildings, storage, roadways, parking areas
and other development. Development of these lands should be limited
to those areas that are visually screened from major public road right-of-ways
and major public trails by existing vegetation or topography. Recreational
uses in these areas are acceptable provided they complement the visual
resources within the area.
Policy/Action 4. Cluster development out of
visually important lands, whenever possible, or cluster within forested
areas.
Policy/Action 5. Utilize Transfer of Development
Rights (TDRs) to transfer density from areas of highest visual importance
to less visually sensitive lands.
5.1 Lands of high visual importance should
not be designated as TDR receiving areas.
Policy/Action 6. Identify and consider acquisition
of lands of highest visual importance for open space purposes where
development cannot be visually screened because of site conditions (e.g.,
lack of vegetation).
Goal B. Ensure that new development
is designed in a visually sensitive manner, complementing the surrounding
natural environment.
Policy/Action 1. New development should be subject
to design standards and prescriptions for the mitigation of visual impacts
to protect and preserve the rural landscapes.
1.1 Amend the Land Use
and Development Code to, where appropriate, incorporate the specific
recommendations of the Draft Summit County Design Standards and Guidelines.
1.2 Develop architectural design standards which
promote a sense of place and community without mandating a monotonous
style or inhibiting innovative design .
1.3 Encourage innovative design and non-repetitive
architecture to avoid excessive similarity in building design, while
still promoting architecture appropriate to the setting.
Policy/Action 2. Ensure that development density
is consistent with the goal of protecting views of visually important
lands.
Policy/Action 3. Mitigate visual impacts by requiring
the following, where appropriate: the use of building materials, building
design (e.g., building mass, size, and height), colors, location of
structures, and landscaping so that structures blend into the natural
landscape.
Policy/Action 4. Require the preservation
of significant trees, where feasible.
Policy/Action
5. Amend the Land Use and Development Code to require the
undergrounding of new utility lines for new development.
Policy/Action 6. The placement of new utilities
should be done a visually acceptable manner, maintaining existing
vegetation and landscapes to the maximum extent possible.
Policy/Action
7. Require building envelopes and disturbance envelopes to be established
in all new subdivisions to minimize visual and environmental impacts.
[Proposed mandatory provision]
Policy/Action 8. Preserve and protect existing significant
natural features, such as distinctive landforms (rock outcrops).
Policy/Action 9. Larger development projects (12
units or more) should provide a usable outdoor place, to provide
a focal point for the site that is readily accessed by residents of
the project.
Policy/Action 10. Orient buildings to fit with the
natural topography, clustering buildings when appropriate so that
natural features and usable outdoor spaces are maintained and solar
access is maximized.
Policy/Action 11. Work with appropriate parties to
ensure that the visual impacts of new roads are minimized and that
roads maintain character with their surroundings.
Policy/Action 12. Provide a visual continuity in the
landscape design of a site compared to the surrounding area by “feathering”
the edge of the forest into the site, rather than creating abrupt
transitions between development and the natural landscape.
Goal C. The open character of meadows and other
open landscapes should be retained.
Policy/Action 1. Wherever possible, avoid locating
buildings in meadows and open landscapes. Where it is not possible
to avoid these areas, development should be located and designed according
to the following guidelines:
1.1
When possible, buildings should be located behind landforms,
berms, or along forest edges to provide maximum screening.
1.2
Buildings that must be located in open areas should
be clustered, designed and intensely landscaped to blend into their
surroundings to the maximum extent possible.
Goal D. The visual dominance of forested
areas should be retained.
Policy/Action 1. Where possible, development should
be located in forested areas where it can be screened from view, while
still maintaining the overall visual character of the forest.
Policy/Action 2. Building heights in forested areas should not penetrate the
tree canopy.
Policy/Action
3. Removal of trees on steep slopes and ridgelines should be discouraged
Policy/Action 4. In partially forested areas, buildings
should be located behind the front edge of trees to maximize the visual
quality of the forest and gain the maximum effect of screening.
Goal E. Avoid or minimize development
impacts on steep hillsides and ridgelines.
Policy/Action 1. Development on ridgelines and steep
slopes should be avoided wherever possible. Where no feasible alternative
exists, buildings on ridgelines and slopes should be located and designed
so that the existing visual dominance of the natural landform, vegetation
and topography is maintained.
Policy/Action 2. Minimize the need for grading, earth
moving, vegetation removal, and site disturbance related to development
on sloped areas.
Policy/Action 3. Grading or earth moving to create
a flat building pad on a slope should be discouraged, instead, buildings
should be stepped to fit with the natural terrain.
Green Design
Goal F. Accelerate the adoption of green
building practices, technologies, policies and standards in residential
and commercial development.
Policy/Action 1. Explore options, programs and financial
incentives to achieve a higher level of green design in new home construction
and remodeling.
1.1. To the extent practical, develop a viable green
building rating system(s) to encourage utilization of green and energy
efficient building practices (e.g., Leadership in Energy and Environmental
Design).
1.2
Develop a ‘Built
Green’ checklist and standards to further support a common message
to the consumer and the building community about energy, water and
durable products.
Policy/Action
2. Expand the County’s supply of green buildings and environmentally
sensitive structures.
2.1 Encourage home builders to use technologies,
products and practices which:
·
Conserve water.
·
Provide greater energy
and materials efficiency.
·
Reduce resource depletion
and pollution.
·
Protect indoor air
quality.
·
Result in more durable,
comfortable home.
Policy/Action 3. Explore developing a model energy
code for buildings that sets minimum energy efficiency standards for
building construction.
Policy/Action 4. Amend the Code to require all new public buildings
to meet green standards.
Policy/Action 5. Promote and provide awareness and
technical assistance programs, resources and information to the development
community and homeowners (e.g., green built, energy efficient and environmentally
responsible buildings or related areas).
5.1 Educate the home buying public how homes built
to green standards may be more affordable, due to lower operating
cost and higher performance, and may also offer home buyers greater
comfort, reduced maintenance cost and higher resale value.
