GUIDE TO LANDSCAPE WATER -REQUIREMENT CATEGORIES
8/22/94
This guide is intended as an aid in fulfilling the City's water conservation landscape standard
requiring that landscape plans include the total area of each landscape category, as distinguished by
water requirements. Landscape water -requirement categories are listed below, with representative
plants. This is obviously not a comprehensive list; it is only intended to provide some direction in
identifying the appropriate category. A more extensive plant list will eventually be developed.
TURFGRASS
1. High:
Kentucky bluegrass and/or perennial ryegrass
2. Moderate:
tall fescue
3. Low:
buffalograss and/or blue grama grass
ORNAMENTAL PLANTING BEDS
1. High:
hosta, fern, dogwood, willow, spruce, fir, Norway or Sugar Maple
2. Moderate:
ajuga, periwinkle, columbine, daylily, thyme, candytuft, sweet woodruff, iris, potentilla,
viburnums, green ash, honeylocust, hackberry, Kentucky coffeetree
3. Low:
gaillardia, hardy ice plant, Russian sage, purple coneflower, coreopsis, snow -in -summer,
yarrow, Iamb's ear, Siberian peashrub, junipers, ponderosa pine, Russian hawthorne, western
sandcherry, gambel oak, three -leaf sumac, ginnala maple
4. Very low:
cacti, sedums, hens and chicks, poppy mallow, evening primrose, mountain mahogany,
rabbitbrush, sagebrush, pinyon pine
NON -PLANT AREA
Non -irrigated, non -plant areas of the landscape, other than parking lots and drives. Includes such
areas as walks, patios, and other "hardscapes".

LANDSCAPE STANDARDS
A. Landscape Plan
1. The landscape plan shall contain a general note calling for the review and approval by the
City of Fort Collins of any required irrigation system for the landscape.
2. The landscape plan shall include the total area (in square feet) for each landscape category.
Landscape categories are distinguished by their water requirements and intended maintenance
level. Examples of possible categories include, but are not limited to, high water turfgrass,
low water turfgrass, low water planting beds, moderate water planting beds, and non -plant
areas (paved areas, etc.). (See the attached list for a general guide for this item.)
B. Plants and Design
1. To the extent practical, plants with similar water requirements shall be grouped together on
the same irrigation zones.
2. The landscape shall be designed with efficient irrigation layout in mind. For example, the
dimensions of turfgrass areas should be in multiples of the radius of throw of the specified
sprinklers, and the geometry is such that overspray is minimized.
3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be
designed to minimize water runoff and to take advantage of the water that does run off.
4. Where south -facing berms of 25% slope or greater exist, the plants used should be lower
water -requiring species.
5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such as
between sidewalk and street, they should be planted with lower water -requiring plant species.
C. Use of Mulches
1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic, and
shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of
barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of planting.
D. Natural Area Preservation
1. If there are portions of the site that are worthy of preservation, the alternative of leaving
them undisturbed or with only slight improvements should be considered. The worthiness of
such sites shall be determined by the City's Natural Resources Director.

HOW WILL THE STANDARDS BE ENFORCED?
The landscape plan must meet the landscape standards in order for the associated development to be
approved by the City. The irrigation plan must meet the irrigation standards prior to the issuance of
a building permit for the associated construction. Both the landscape and irrigation systems must be
installed according to the approved plans, or an acceptable bond deposited with the City, prior to the
issuance of a certificate of occupancy for the associated building(s).
IS THEIR ANY FLEXIBILITY IN THESE STANDARDS?
One important characteristic of these standards is that they include a certain amount of flexibility.
Some of the individual standards are strongly worded with "shall", whereas others use the softer
phrases such as "should" or "to the extent practical". This approach allows for the establishment of
mandatory standards for the landscaping techniques that are most important to water conservation and
that are more easily met, while still retaining some flexibility for the techniques that need to be
assessed on a case by case basis.
ARE THERE OTHER WATER -CONSERVING LANDSCAPING PRAC77CES THAT THE CITY
ENCOURAGES?
Although the following landscape design and construction practices are not required by the City, they
are strongly encouraged:
• An analysis of the landscaping soil on the site by a soil testing laboratory is extremely useful. At
a minimum, the test should determine the soil texture, percentage of organic matter, major
nutrient levels, and pH. Any horticultural recommendations from the testing lab should be
followed.
The soils in the Fort Collins area are typically very low in organic content and high in clay.
There is significant horticultural benefit and potential water -saving benefit to incorporating at
least three cubic yards of composted manure per 1000 square feet of landscape area, to a depth
of six inches or more.
The use of lower water -requiring grass species for turf and ornamental areas is strongly
encouraged. Tall fescue grass is an excellent water -conserving substitute in most situations
where Kentucky bluegrass would otherwise be used. Buffalograss, blue grama grass, little
bluestem, sideoats grams, smooth bromegrass, crested wheatgrass and western wheatgrass should
be considered for low maintenance, more "natural -looking" applications. All of these grasses
have their particular advantages and disadvantages. There is no single best turfgrass to use for
all situations. Contact the Water Utility at 221-6681 or the CSU Department of Horticulture at
491-7019 for more information on grasses.
FOR MORE 1NFORMA77ON.
The City Water Utility is a good resource for information on water -conserving landscaping and
irrigation practices. If you would like more information on these topics, or if you have any questions
or comments about these standards, contact the City's Water Conservation Specialist at 221-6681.
CITY OF FORT COLLINS
WATER CONSERVATION STANDARDS FOR LANDSCAPES
9/16194
GENERAL INFORMATION
WHAT IS THE PURPOSE OF THESE STANDARDS?
In the spring of 1994 the Fort Collins City Council adopted water conservation standards for both
landscaping and landscape irrigation systems. (The landscape irrigation standards are available as a
separate document.) The purpose of these standards is to foster the conservation of water used for
landscape watering. The specific intent is to promote the installation of landscapes that require less
water, and irrigation systems that are able to efficiently and uniformly apply that amount of water.
However, it is recognized that these measures will not necessarily preclude the person scheduling the
irrigation from wasting water by applying more than is necessary. For that reason, these measures
are seen as only one piece of an overall water conservation plan.
WHAT WAS THE PROCESS USED IN ESTABLISHING THESE STANDARDS?
These standards represent a year -long process that included considerable opportunities for input from
"potentially -affected interests", relevant City staff, citizen advisory boards, and city council. More
specifically, there were two general opportunities for local developers and "green industry"
professionals to contribute written or verbal comments. Furthermore, two committees were convened
to draft the content of the standards; one committee composed of local landscape designers and
contractors for the landscaping standards, and the other committee consisted of local irrigation
suppliers, designers and contractors for the irrigation standards.
WHAT TFPE OF PROJECTS ARE SUBJECT TO THE STANDARDS?
These standards apply to all projects within the Fort Collins city limits where the City requires the
submittal of a landscape plan as part of the development review process. In general, this includes all
commercial, industrial, institutional, and multi -family projects. It also includes duplexes that are
being constructed as part of a planned unit development. Although it does apply to common areas of
single family developments, it does not apply to the landscapes or irrigation systems of individual
single family residential lots.
ARE THESE STANDARDS APPLICABLE TO EXIS77NG LANDSCAPES AND IRRIGATION
SYSTEMS?
No. These standards will be applied to all new projects, beginning with those submitted for the
October 24, 1994 Planning and Zoning Board meeting.
AT WHAT POINT IN 77-IE DESIGN PROCESS WILL THE LANDSCAPE AND IRRIGA770N PLANS
BE REVIEWED?
Landscape plans will be reviewed as part of the development review process. Irrigation plans will be
reviewed as part of the construction permit review process.

The attached Species Use List has been developed by the City Forestry Division
staff. Ratings are based on an evaluation of growth performance for species at
each of the areas listed above.
Those species rated as 3, 4 and 5 should be the dominate types used on all City
property. Those rated as 3 should be used only in small quantities. Other
species can be used with special approval. Lower rated species should be used
occasionally on appropriate sites and only when their specific growth
requirements can be provided for.
The Species Use List applies to all tree plantings on City of Fort Collins
property. The growth and performance of trees on other properties may be
somewhat different so judgement should be used in applying this list to other
areas. Also, the management objectives on private property are different and
reflect small numbers of trees instead of the City's large tree population. More
intensive maintenance and higher costs per tree are usually acceptable on private
lands.
The species listed and their ratings will be updated as new species are planted
and evaluated, and more information becomes available.

installation, but the amount of the same shall be reduced
after installation is completed to twenty-five percent
(25%) of the actual cost of such landscaping. If the
required landscaping is already installed prior to issu-
ance of a Certificate of Occupancy, a bond in the amount
of twenty-five percent (25%) of the actual cost of the
landscaping guaranteeing continued maintenance and
replacement of the same for a period of two (2) years
shall be required as a condition of issuance of the Certi-
ficate of Occupancy. Any bond, cash deposit, or equiva-
lent, deposited pursuant to this requirement shall be
released upon certification by the Building Inspector that
the required landscaping program has been completed and
maintained in accordance with the requirements of the
bond. If any landscaping required pursuant to this sec-
tion is not maintained in accordance with the requirements
of the final plan, such failure to maintain the landscap-

except as waived by the approved preliminary plan for the
planned unit development. The subdivision shall contain proper
dedications for public streets, utility easements, and all
other public rights required by the preliminary plan. Approval
by the Planning and Zoning Board of the final plan and subdivi-
sion plat shall be required before filing of the subdivision
plat or issuance of building permits.
(e) Final utility plans. Final detailed engineering for sewer,
water, electrical, street improvements and other public
improvements must be submitted to and approved by the City, and
the developer shall execute an agreement in proper form provid-

SUGGESTED NATIVE PLANTS FOR HORTICULTURAL USE IN NORTHEASTERN COLORADO
Prepared by the Colorado Native Plant Society
Horticulture and Rehabilitation Committee
P. 0. Box 200
Fort Collins, Colorado 80522
Colorado produces a wealth of native plants - colorful flowering species,
grasses, shrubs and trees which are particularly well adapted to our
variable climate, soils, temperatures and elevations, since they have
evolved over many thousands of years. Some have been used in Colorado
gardens and landscaping but many have been overlooked in our enthusiasm
for exotic imported species which may be less well suited to our
environment (or may escape and do too well to the detriment of natives).
The Colorado Native Plant Society encourages the use of native plants
In landscaping, both because of their adaptability and because we like
the idea of Colorado looking like Colorado with unique regional
horticulture which sets us apart from other parts of the country.
Some native seeds are available from distributors in the region. It
Is always better to buy seeds from as near your own area as possible.
A list of regional seed suppliers follows. Other seeds would need to
be gathered from the wild. (Please note: Gather ONLY seeds from plants
which are plentiful. Many beautiful ones are. Seeds should NOT be
gathered from rare or endangered species except for research purposes).
For sources of started plants, check regional nurseries. More natives
are being grown all the time and as the demand increases, so will the
supply.

ployed in a proposed project. Regardless of the accuracy of this
estimate, ho'irever, an employer or developer should be aware that
the ordinance requirement is an ongoing performance stanaara, and
if the required ratio of parking is not provided at any point in
time, it will be considered a violation of the zoning ordinance.
If necessary, contact the Planning Division for reference informa-
tion on average employee -per -square -foot ratios for typical busi-
ness and industrial uses.

Site/Landscape plans for commercial uses submitted to the Planning and
Zoning Board will be reviewed relative to the following criteria:
1. The plan should indicate a well designed landscape treatment of
exterior spaces which measurably improves the overall quality of
the project. This will normally require that landscaped area cons-
titute from 122 to 17% of the site's total area, depending upon
design objectives, and intensity or, quantity of planting materials.
2. The plan should provide landscaped separation and screening of parking
lots and vehicular use areas from adjacent sidewalks and streets in
the public R.O.W. This landscaped buffer should normally be at least
ten (10) feet wide to allow adequate room for shade trees planted in
this buffer area. Shade trees should be planted at approximately 4
foot intervals along allpublic street frontages.
3. The plan should provide landscaped "islands" in parking lots with
more than a single driveway aisle. Each of these islands should
include at least one full size tree and must have at least 80 sq. ft.
of ground area per tree to allow for root aeration. A mix of deciduous
and coniferous trees and shrubs will be encouraged. The purpose of these
islands is to improve parking lots by providing visual relief with verti-
cal landscape treatment and physical relief with seasonal shading.
4. The plan should provide well defined circulation for both vehicles and
pedestrians. The plan should specifically address the interrelation of
pedestrian and vehicular circulation and indicate proposed treatment for
points of conflict.
5. The plan should preserve mature healthy trees on the site.
6. The plan should provide for permanent irrigation of all landscape
materials. Normally this will require an automatic underground
irrigation system.

LANDSCAPE STANDARDS
A. Landscape Plan
1. The landscape plan shall contain a general note calling for the review and approval by the
City of Fort Collins of any required irrigation system for the landscape.
2. The landscape plan shall include the total area (in square feet) for each landscape category.
Landscape categories are distinguished by their water requirements and intended maintenance
level. Examples of possible categories include, but are not limited to, high water turfgrass,
low water turfgrass, low water planting beds, moderate water planting beds, and non -plant
areas (paved areas, etc.). (See the attached guide for this item.)
B. Plants and Design
1. To the extent practical, plants with similar water requirements shall be grouped together on
the same irrigation zones.
2. The landscape shall be designed with efficient irrigation layout in mind. For example, the
dimensions of turfgrass areas should be in multiples of the radius of throw of the specified
sprinklers, and the geometry is such that overspray is minimized.
3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be
designed to minimize water runoff and to take advantage of the water that does run off.
4. Where south -facing berms of 25 % slope or greater exist, the plants used should be lower
water -requiring species.
5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such as
between sidewalk and street, they should be planted with lower water -requiring plant species.
C. Use of Mulches
1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic, and
shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of
barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of planting.
D. Natural Area Preservation
1. If there are portions of the site that are worthy of preservation, the alternative of leaving
them undisturbed or with only slight improvements should be considered. The worthiness of
such sites shall be determined by the City's Natural Resources Director.
3
HOW WILL THE STANDARDS BE ENFORCED?
The landscape plan must meet the landscape standards in order for the associated development to be
approved by the City. The irrigation plan must meet the irrigation standards prior to the issuance of
a building permit for the associated construction. Both the landscape and irrigation systems must be
installed according to the approved plans, or an acceptable bond deposited with the City, prior to the
issuance of a certificate of occupancy for the associated building(s).
IS THEIR ANY FLEXIBILITY IN THESE STANDARDS?
One important characteristic of these standards is that they include a certain amount of flexibility.
Some of the individual standards are strongly worded with "shall", whereas others use the sorter
phrases such as "should" or "to the extent practical". This approach allows for the establishment of
mandatory standards for the landscaping techniques that are most important to water conservation and
that are more easily met, while still retaining some flexibility for the techniques that need to be
assessed on a case by case basis.
ARE THERE OTHER WATER -CONSERVING LANDSCAPING PRAC77CES THAT THE CITY
ENCOURAGES?
Although the following landscape design and construction practices are not required by the City, they
are strongly encouraged:
• An analysis of the landscaping soil on the site by a soil testing laboratory is extremely useful. At
a minimum, the test should determine the soil texture, percentage of organic matter, major
nutrient levels, and pH. Any horticultural recommendations from the testing lab should be
followed.
The soils in the Fort Collins area are typically very low in organic content and high in clay.
There is significant horticultural benefit and potential water -saving benefit to incorporating at
least three cubic yards of composted manure per 1000 square feet of landscape area, to a depth
of six inches or more.
The use of lower water -requiring grass species for turf and ornamental areas is strongly
encouraged. Tall fescue grass is an excellent water -conserving substitute in most situations
where Kentucky bluegrass would otherwise be used. Buffalograss, blue grama grass, little
bluestem, sideoats grama, smooth bromegrass, crested wheatgrass and western wheatgrass should
be considered for low maintenance, more "natural -looking" applications. All of these grasses
have their particular advantages and disadvantages. There is no single best turfgrass to use for
all situations. Contact the Water Utility at 221-6681 or the CSU Department of Horticulture at
491-7019 for more information on grasses.
FOR MORE INFORMA770N:
The City Water Utility is a good resource for information on water -conserving landscaping and
irrigation practices. If you would like more information on these topics, or if you have any questions
or comments about these standards, contact the City's Water Conservation Specialist at 221-6681.

CITY OF FORT COLLINS
WATER CONSERVATION STANDARDS FOR LANDSCAPES
10/94
GENERAL INFORMATION
WHAT IS THE PURPOSE OF THESE STANDARDS?
In the spring of 1994 the Fort Collins City Council adopted water conservation standards for both
landscaping and landscape irrigation systems. (The landscape irrigation standards are available as a
separate document.) The purpose of these standards is to foster the conservation of water used for
landscape watering. The specific intent is to promote the installation of landscapes that require less
water, and irrigation systems that are able to efficiently and uniformly apply that amount of water.
However, it is recognized that these measures will not necessarily preclude the person scheduling the
irrigation from wasting water by applying more than is necessary. For that reason, these measures
are seen as only one piece of an overall water conservation plan.
WHAT WAS THE PROCESS USED IN ESTABLISHING THESE STANDARDS?
These standards represent a year -long process that included considerable opportunities for input from
"potentially -affected interests", relevant City staff, citizen advisory boards, and city council. More
specifically, there were two general opportunities for local developers and "green industry"
professionals to contribute written or verbal comments. Furthermore, two committees were convened
to draft the content of the standards; one committee composed of local landscape designers and
contractors for the landscaping standards, and the other committee consisted of local irrigation
suppliers, designers and contractors for the irrigation standards.
WHAT TYPE OF PROJECTS ARE SUBJECT TO THE STANDARDS?
These standards apply to all projects within the Fort Collins city limits where the City requires the
submittal of a landscape plan as part of the development review process. In general, this includes all
commercial, industrial, institutional, and multi -family projects. It also includes duplexes that are
being constructed as part of a planned unit development. Although it does apply to common areas of
single family developments, it does not apply to the landscapes or irrigation systems of individual
single family residential lots.
ARE THESE STANDARDS APPLICABLE TO EXISTING LANDSCAPES AND IRRIGA77ON
SYSTEMS?
No. These standards will be applied to all new projects, beginning with those submitted for the
October 24, 1994 Planning and Zoning Board meeting.
AT WHAT POINT IN THE DESIGN PROCESS WILL THE LANDSCAPE AND IRRIGATION PLANS
BE REVIEWED?
Landscape plans will be reviewed as part of the development review process. Irrigation plans will be
reviewed as part of the construction permit review process.
2. The landscape shall be designed with efficient irrigation layout in mind. For example, the
dimensions of turfgrass areas should be in multiples of the radius of throw of the specified
sprinklers, and the geometry is such that overspray is minimized.
3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be
designed to minimize water runoff and to take advantage of the water that does run off.
4. Where south -facing berms of 25% slope or greater exist, the plants used should be lower
water -requiring species.
El5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such
as between sidewalk and street, they should be planted with lower water -requiring plant
species.
MULCHES
1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic,
and shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of
barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of
planting.

Dear Kint,
Staff has reviewed your documents for the Glenmoor Drive P.U.D.,
that were submitted on April 24, 1995, and would like to offer the
following comments:
1. As you were notified by telephone on May 3, 1995, this
combined Preliminary /Final P.U.D. submittal does not meet
Final P.U.D. requirements. Staff has therefore downgraded the
submittal to a Preliminary P.U.D. only. The Plat,
Site/Landscape Plan, and elevations should be revised to state
"Preliminary Plat", Preliminary Site/Landscape Plan" and
"Preliminary Elevations." Per your request, the fees which
you have paid will be held by the City and adjusted
accordingly. This may result in additional review fees being
owed to the City.
2. The Stormwater Utility Department comments are forthcoming.
It appears that there are significant issues that need to be
addressed. Please contact Basil Hamdin at 221-6589 to discuss
these concerns.
3. Please show building envelopes, setbacks, and dimensions of
all buildings on the Site/Landscape Plan. The alternative
scheme for duplex construction comes close, but doesn't show
a rear setback.
4. Please add the following note to the Site/Landscape Plan:
"Landscaping of common open space areas shall be installed or
secured with a letter of credit, escrow, or performance bond
for 125% of the value of the landscaping prior to the issuance
of a Certificate of Occupancy."
5. Fire hydrants must be located within 400' of all dwelling
units, capable of providing 1,000 g.p.m. with 20 p.s.i.
residual. An additional hydrant will be needed along Glenmoor
Drive.
6. It does not appear that the proposed development adequately
addresses wetland and stormwater management issues. Existing
wetlands need to be delineated by a licensed wetland
