Memo
TO. Honorable Mayor and Town Council
Thru: Larry Brooks, Town Manager
From: Tambi Katieb, Community Developm
Date April 17, 2003
Re: Revised Landscaping Design Guidelines Resolution 03-16
Summary:
Staff has attached the final draft of revised landscaping guidelines for both the Residential
and Commercial/Industrial portion of our design guidelines (including a revised plant list) for
your review and action.
The Planning & Zoning Commission unanimously adopted the revised guidelines through
Resolution 03-06. Highlights of the proposed revision include:
• Incorporation of the seven principles of xeriscape landscaping on all new projects
through the design review process.
• The limitation on total irrigation area for all landscaping plans of 20%. This means of
the required minimum landscape area per zone district or PUD, only 20% of the total
area may be irrigated.
• Clarification on all landscape plans of the following areas: total irrigated area, spray
irrigated area, drip irrigated area, and sod area. A table indicating total square
footage for each category is now required.
• The required use of a rain sensor on all automatic irrigation systems, to be inspected
prior to the issuance of a Certificate of Occupancy.
• Required adherence to the ERWSD watering schedule as imposed and enforced by
the District.
• An allowance for overhead temporary irrigation to re-establish native seed areas that
would otherwise remain non-irrigated. The allowance is for one year to ensure the
area is established.
• A revised plant list that features more native trees, plants, shrubs, and groundcovers.
The list also indicates water requirements of each recommended material. This list
was reviewed by the local CSU extension office as well as by the chief horticulture
agent in their regional office.

C. _ Residential Landscaping
Design Character
Landscaping in the Town of Avon must recognize the drought conditions that prevail in
our western region, and be tolerant of these drought episodes.' It should harmonize the
building site with both the natural topography and existing vegetation, minimizing
disturbed areas, while respecting the limitations and best uses of water resources in our
municipality.
Landscaping must meet minimum zoning requirements; however, only 20% of the total
landscaped area may be irrigated. Irrigated areas must be delineated on all plans.
Design Guidelines:
1. Landscaping must be designed to incorporate water conserving materials and
techniques through the application of seven fundamental xeriscape landscaping
principles including:
a. -,,Planning and designing a landscaped area that groups plants with similar
water, and sunlight requirements together.
b. Creating practical and appropriate turf areas, (when necessary), utilizing a
lower water-use turf such as buffalograss, blue grama, or turf type tall
fescues and fine fescues.
c. Use of low water demanding plants and dryland seed grass mixes.
d. Use of automatic irrigation systems, designed and operated to conserve
water by applying the right amount of water at the right time.
e. Incorporation of soil amendments, where appropriate for the site and type
of plants proposed.
f. Use of Mulches, such as woodchips, to reduce evaporation potential and
keep the soil cool.
'g. Planting appropriate materials suited to the soil and climate, and
appropriately maintaining the vegetation once established.
2. Preserve and protect as much existing vegetation as possible. Incorporate existing
trees when locating structures.
3. Consideration should be given to use of landscape material for snow fencing,
visual screening and wind breaks when applicable.
4. Plant.materials should be adaptable to the area and selection and placement
should include consideration of function and color coordination. Proposed
materials must be called out on plans. A list of recommended plant species that
are compatible with-various climate zones found in the Town is attached in
Appendix 1..No noxious weeds, as listed in Appendix 2, shall be permitted for
use in the Town.
Irrigation/Wateriiig Requirements:
1. The landscaping site plan must identify the area of approximate installation of an
automatic irrigation system, its maintenance, and intended uses. All landscape
plans must note and delineate all irrigated and sod areas.
2. A rain sensor must be installed with each new irrigation system, in order to
interrupt irrigation in the event of a significant rainfall. Inspection for the rain
sensor will be conducted prior to issuance of a Certificate-of Occupancy.
3. The following table must be provided on all landscape plans:
Landscape Area Provided
% of Lot / Square Footage
Total Irrigated Area
% of Landscaped Area / Square Footage
Spray Area
% of Irrigated Area / Square Footage
Drip Area
of Irrigated Area / Square Footage
Sod Area
% of Irrigated Area /Square Footage
4. All irrigation shall be subject to the watering schedule as imposed by the Eagle
River Water and Sanitation District (ERWSD).
5. Temporary (overhead) sprinkler irrigation is allowed to re-establish native
vegetation and seed mixes on otherwise non-irrigated portions of the landscaped
areas, however, must be removed 1 year after installation. All disturbed areas will
be adequately, reseeded and restored on all projects.
Turf Requirements:
1. The following types of ornamental grasses are recommended: Buffalograss, Blue
Grama, Little Bluestein, Smooth Brome, Crested Wheatgrass or Western
Wheatgrass.
2. In all disturbed•areas, soil must be prepared, with the addition of organic matter,
and tilling the soil as deep as possible. The addition of decomposed organic
matter (compost, composed horse manure, or composted chopped straw or hay) is
required for turf installation.
