part of the this plan cannot be implemented due to site conditions, contact the Landscape Architect for instructions prior to commencing work
4. Four inch steel edging shall be installed between all grass areas and planting beds.
5. All planting beds shall receive 4" small Pine bark mulch.
6. Grades shown in the landscape areas are finish grades, including 6" of topsoil in lawn areas and 12" of topsoil in planting areas.

City of Aspen Water Efficient Landscaping Standards
Non‐Living General Landscape Design Criteria
Organic Mulch:
a. Shall be applied at one (1) cubic yard per eighty (80) square feet at a depth of four (4) inches, and as
appropriate to each species.
b. Shall be applied to the soil surface, not against the plant stem or high against the base of trunks to minimize
disease.
c. Organic mulch material includes bark and wood chips. Avoid mulch consisting of construction debris such
as pallets.
Inorganic Mulch:
a.Inorganic mulch includes rock, gravel, or pebbles.
b. Rock mulch shall have a minimum depth of two inches (2”).
Soil texture;
Total exchange capacity;
Conductivity;
Organic matter;
Acidity; and
Content of nitrogen (NO3, Phosphorus, Potassium, Zinc, Iron, Copper,
Manganese and Lime).
iii. The soil analysis shall include specific recommendations based on the soil test for the type of plant
material to be grown in each landscaped area. The type and volume of soil amendment shall be
determined by the soil scientist and be consistent with the indigenous soil and the needs of the
plant materials in each area of the landscape.
iv. Upon receipt of the information, the City of Aspen shall approve or deny the soil amendment. If the
amendment is denied, the City of Aspen shall provide information to the project applicant regarding
additional requirements.
Soil Preparation:
a. Amendment shall be tilled to a minimum depth of six inches (6”).
b. Site shall be graded to within two‐tenths of a foot (2/10th’) of the grading plan.
c. Site shall be free of rocks and debris over one inch (1”) diameter in size. Rocks and debris 0.5 inch (0.5”) to
one inch (1”) shall not exceed 5 percent (5%) by volume and gravel 0.6 inch (0.6”) to 1.25 inches (1.25”)
shall not exceed 5 percent (5%) by volume. Particles such as concrete, brick, glass, metal, wood or plastic
greater than one inch (1”) shall not be allowed. The total volume of these materials smaller than one inch
(1”) shall not exceed 5 percent (5%).
d.Site shall be free of dirt clods over three‐quarter inch (3/4”) diameter in size. Dryland
seed areas may contain dirt clods up to two inch (2”) diameter in size.
i. Stockpiling ‐ Stripping and stockpiling of indigenous soil (topsoil) shall be required during construction
(except as waived by the City of Aspen). The replacement of this soil, plus additional soil amendments,
are critical to successful plant material establishment, ongoing health, and efficient use of water through
the life of the project.
e. The soil shall have no herbicides, heavy metals, biological toxins or hydrocarbons that impact plant growth
or exceed the EPA’s standards for soil contaminant.
f. All applicable soil criteria and standards shall be noted on the landscape design plan. Written verification of
approved soil amendment type and volume is required. Projects with inadequate soil amendment and
preparation will not be approved.
Soil Inspection:
a. Soil inspections prior to installation of plant material may be conducted by the City of Aspen as deemed
necessary and shall include a review of adherence to all criteria and performance standards.
b. Written documentation reflecting approved volume and type of soil amendment is required upon
inspection.
Soil Amendment:
a. Topsoil of irrigated grasses (including turf) , shrubs, perennials, and annuals shall be a sandy loam to a
depth of at least 6 inches (6") containing at least 5 percent (5%) organic matter by volume.
b. Tree soil must be a sandy loam and 36" deep for areas where trees are planted. The total soil depth shall
have at least one to three percent (1-3%) organic matter by volume. (NOTE: If in turf, top soil should be 6"
and have 5% organic matter by volume.) In good existing soils, dig and turn the soils to three times the
dimension of the root ball. hard or compacted sub soil or lower soil layers should be broken up to create
adequate drainage and avoid trapping water creating saturated and anaerobic conditions in the upper
soil layer. In newly developed planting sites, soil depth shall be 20' diameter around the trees to a depth of 36"
c. Soil amendment organic matter shall consist of either Class I and Class II compost.
City of Aspen Water Efficient Landscaping Standards
Soil Criteria
g. Removing sod and amending soild under protected trees requires hand grubbing no deeper
than 4 inches. Any additional soil above existing grade limited to a maximum 3 inches (3")
Soil Inspection:
a. Soil inspections prior to installation of plant material may be conducted by the City of Aspen as deemed
necessary and shall include a review of adherence to all criteria and performance standards.
b. Written documentation reflecting approved volume and type of soil amendment is required upon

Snow-melted pervious
paving (Civil Sheet
A0-04) within the drip
line of existing trees will
require City Forester
review and written
approval.
Landscaping in the City ROW
should be in character with the
surrounding neighborhood.
Adjacent properties and the West
End in general are landscaped
primarily with turf grass. Revise
accordingly.
