NOTES:
1. This chart is intended as an irrigation design aid, related to the City's water conservation standard that limits
the size of irrigated turfgrass area as a function of the tap size. The above values are calculated assuming peak
daily evapotranspiration rates of 0.25 inches for Kentucky bluegrass and 0.20 inches for tall fescue. For the
purposes of the calculations, it is assumed that the irrigation efficiency and tap utilization efficiency are equal
to 100%, and the maximum time of irrigation is 8 hours. More realistically, however, this would be equivalent
to irrigation and tap utilization efficiencies of 80%, and a maximum time of irrigation of 12 hours.
2. These maximum discharges assume a disk -type meter. In certain cases of irrigation -only taps that are 1-1/2"
or larger, turbine meters are allowed, which have higher maximum discharge limits. Contact the City Water
Utiliies for more information.

INSTRUCTIONS TO IRRIGATION DESIGNERS
FOR COMPLETING AN ANNUAL WATER USE C14ART
1. The above water use chart, including the notes, is an example of what the City of Fort Collins requires
to be included on irrigation plans.
2. The discharge figures for each lateral can be calculated by summing the appropriate discharge values
in the manufacturers' catalogs for the specified sprinklers, bubblers, or drip emitters.
3. Irrigated areas for each lateral can be calculated using scales and/or planimeters. This should be a
"best estimate", splitting areas between zones as necessary. For drip irrigation, the irrigated area
should approximate the area actually wetted by the emitters. As a general guideline, you can use
one square foot for each perennial, four square feet for each shrub, and twelve square feet for each
tree.
4. To calculate precipitation rate (inches per hour), multiply the discharge (gallons per minute) times the
conversion factor of 96.26, and then divide by the irrigated area (square feet).
5. The average annual depth of irrigation can be determined by referring to the guide on the back of this
sheet.
6. The annual volume of water (gallons) can be determined by multiplying the irrigated area (square feet)
by the average annual depth of irrigation (inches), and then dividing by the conversion factor of 1.6.
7. The annual cost for the water is determined by multiplying the volume of water by the applicable cost
of water. It is the responsibility of the irrigation designer to find out which water district serves the
project, and to make sure the current water cost is used in the calculation. The phone numbers for
22. The irrigation system shall be designed such that the point -of -connection design pressure,
minus the worst case system pressure losses, is greater than or equal to the design sprinkler
operating pressure. (See Attachment C.)
23. The lateral pipe shall be sized such that there is less than or equal to a 10 percent variation
between the highest and lowest sprinkler operating pressures on a zone.
c. All sprinklers, bubblers, or emitters on a zone shall be of the same manufacturer.
Additionally, all spray sprinklers on a zone shall have matched precipitation nozzles,
and the nozzles for all rotary sprinklers on a zone shall be selected to approximate a
uniform precipitation rate.
d. Check valves shall be used on all low-lying sprinklers with 3 feet or more of lateral
pipe head against them, and on all sprinklers along sidewalks.
13. A pressure reducing valve shall be installed on the mainline, or as a feature of the remote
control valves, if it is anticipated that the operating pressure at any spray sprinkler, minus the
maximum recommended pressure for that particular sprinkler, is equal to 20 psi or more.
14. A rain sensor shall be installed with each irrigation system, in order to interrupt irrigation in the
event of a significant rainfall.
15. When drip irrigation is used, emitter discharges within any single zone shall not vary by more
than 5 percent. If necessary because of long runs and/or elevation changes, pressure -
compensating emitters shall be used.
16. Remote control valves shall have flow control stems.
Sprinkler spacing
For both cases below, the radius of throw is defined as the value shown in the manufacturer's
specifications for the specific design operating pressure for the sprinkler.
17. With a square pattern layout, sprinklers shall be spaced no further apart than 1.0 times the
manufacturer's published radius of throw.
18. With a triangular spacing layout, sprinklers shall be spaced no further apart than l .l times the
manufacturer's published radius of throw.
Hydraulic considerations
19. Where Kentucky bluegrass and/or Perennial Ryegrass is used for turfgrass, the tap size shall be
sufficiently sized to deliver 0.25 inches of irrigation water over the turfgrass area within an 8
hour period. Where Turf -type Tall Fescue is used, the tap size shall be sufficiently sized to
deliver 0.20 inches of irrigation water over the turfgrass area within an 8 hour period. For
special circumstances, the City may allow exceptions to this standard. (See Attachment B)
20. The maximum system discharge shall be less than or equal to the maximum allowable, relative
to the meter size, as determined by the City Water Utilities. This shall be as follows: 5/8" - 10
gpm, 1" - 25 gpm, 1-1/2" - 50 gpm, 2" - 80 gpm, 3" - 160 gpm. These maximum discharges
assume a disk -type meter. In certain cases of irrigation -only taps that are 1-1/2" or larger,
turbine meters are allowed, which have somewhat higher maximum discharge limits. Contact
the City Water Utilities for more information.
21. The maximum velocities shall be less than or equal to 5.0 feet per second for mainline pipe and
less than or equal to 7.5 feet per second for lateral pipe. (See Attachment B)
4. On steep grades, an irrigation method with a lower precipitation rate shall be used, in order to
minimize runoff. Additionally, these areas shall be zoned separately, if practical.
5. Areas with significantly different solar exposures shall be zoned separately, when practical.
6. Different types of irrigation equipment (drip, micro -spray, spray, rotary, etc.) shall not be
combined on the same zone. As an exception, drip and micro -spray equipment are permissible
on the same zone.
7. As much as practical, the irrigation method shall be selected to correlate with the plant density.
For example, drip irrigation or bubblers should be used for sparsely -planted trees and shrubs,
and sprinklers should be used for turfgrass.
8. The type of sprinkler and associated nozzles should be selected to correlate with the size and
geometry of the zone being irrigated. For example, pop-up spray sprinklers should be used for
smaller and more chopped up areas. As a rule of thumb, sprinklers should be spaced no closer
than 75 percent of the maximum radius of throw for the given sprinkler and nozzle.
Equipment selection
9. A master valve should be installed on all irrigation systems with a tap of 2 inches or larger.
10. For irrigation systems that are on a combined -use tap, with a water meter installed further
upstream to measure total water use, the installation of an irrigation -only sub -meter should be
considered. This sub -meter would enable the owner and landscape maintenance contractor to
more easily determine water use for irrigation, and would not be used for billing, purposes. The
cost of installation and maintenance of the sub -meter shall be borne by the owner of the
property, and not by the City. All such sub -meters shall be installed in accordance with the
specifications established by the City Water Utilities.
11. The irrigation controller shall have a minimum of the following capabilities/features:
a. multiple program
b. percent watering
c. multiple starts per day
d. a large enough number of stations to prevent the necessity of combining zones on a
single station that have dissimilar water requirements or precipitation rates, or exceed
the hydraulic limitations of the tap.
12. Sprinklers and nozzles shall meet the following requirements:
a. Spray sprinklers in turf areas shall have a minimum 3-1/2 inch pop-up riser height.
b. The coverage arcs and radius of throw shall be selected and adjusted to water only
vegetated areas and minimize overspray onto hard -surfaces, buildings, fences, etc.
City of Fort Collins
LANDSCAPE IRRIGATION SYSTEM Standards for Water Conservation
Irrigation Plan
If areas of planting are extensive, the installation of an underground irrigation system shall be
required and a final irrigation plan shall be submitted and approved by the City, prior to the
issuance of the first building permit, or if no building permit is required, prior to the
commencement of construction. If the water requirements of the plant material are low enough
to be met with natural precipitation, and if a means of temporary irrigation is available to
establish the plant material, the City may waive the requirement for an underground irrigation
system. When required, the irrigation plan shall be accurate and clear, drawn to the same scale
as the associated landscape plan, and include the following:
a. the square footage of irrigation zones, lateral precipitation rates (inches/hour), and
seasonal water use and cost. The seasonal water use data shall reflect the water
requirements of the plants identified in the landscape plan associated with the
irrigation plan. The irrigation plan shall reference the specific landscape plan, with its
date and the designer's name. (Example and directions provided on Attachment A.)
b. a general note stating the point -of -connection design pressure and the peak flow. For
example, "The system design assumes a minimum dynamic pressure for the irrigation
system of 75 psi at a maximum discharge of 50 gpm at the 1-1/2-inch tap and point -
of -connection. The irrigation contractor shall verify pressure and flow on site prior to
construction."
c. the design criteria to assist the installer with field adjustments, in a general note or in
the legend. The criteria shall include the sprinkler and nozzle specifications, the
sprinkler discharge at the design operating pressure, and the maximum distance
between sprinklers.
d. a general note stating that "Any field adjustment or re -design of this irrigation system
must conform to the City of Fort Collins' landscape irrigation standards."
e. in the specifications, or as a general note, a requirement for the contractor installing
the system to provide the owner with as -built drawings after the completion of the
installation.
f. details of the installation methods for bubblers or drip emitters, when the irrigation
design includes these components. It must also include the number and discharge rate
of emitters or bubblers per type of plant material.
Irrigation methods and layout
2. Where untreated, raw, water is available from a nearby irrigation ditch or lake, it should be
considered as a possible water source.
3. As much as practical, plants with dissimilar water requirements shall not be irrigated on the
same zone. For example, turfgrass areas should be on separate zones from planting beds.

LANDSCAPING STANDARDS for Water Conservation
Landscape Plan Requirements
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 based on water requirements. For a list of possible categories, see the
Guide to Landscape Water -Requirement Categories on the reverse side of this page.
Design Considerations
3. To the extent practical, plants with similar water requirements shall be grouped together on the
same irrigation zones.
4. 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 should be such that overspray is minimized.
5. 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.
6. Where south -facing berms of 25% slope or greater exist, the plants used should be lower water -
requiring species.
7. 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.
8. 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.
Natural Area Preservation
9. 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.
Other good practices for water -efficient landscapes, but not required
Send soil samples to a testing laboratory to analyze nutrient and fertilizer needs. For
most soils, add at least 3 cubic yards of compost per 1,000 square feet. Rototill to a depth
of 6 to 8 inches.
Consider using lower water -requiring turf and ornamental grasses. Tall fescue is a good
substitute for Kentucky bluegrass in many situations. Buffalograss, blue grama, little
bluestem, sideoats grama, smooth brome, crested wheatgrass and western wheatgrass are
grasses that work well in areas where a natural look is desirable. For more information
about these grasses, call the CSU Department of Horticulture at 491-7019.
City of Fort Collins
Water Conservation Standards for
LANDSCAPING and LANDSCAPE IRRIGATION SYSTEMS
General Information
What are the water conservtion standards?
There are two separate standards for water conservation; landscaping and landscape
irrigation systems. The standards for Landscaping promote the installation of landscapes
that require less water. The standards for Landscape Irrigation Systems ensure that the
irrigation system is designed to efficiently apply the amount of water the landscape needs.
What projects are subject to the standards?
All projects within the city limits that are required to submit a landscape plan to the City
as part of the development review process. In general, this includes all commercial,
industrial, institutional, and multi -family projects. Duplexes are also included when they
are part of a planned unit development. Note that the standards apply to common areas of
single-family developments, but do not apply to single-family residential lots.
What do I have to do to comply with the standards?
1. Submit a landscape plan as part of the development review process. The plan must
meet the standards before the development plan is approved.
2. Submit an irrigation plan as part of the construction permit review process. The
City will review the plan, and then inspect the system after installation. The
irrigation plan and system inspection must be approved by the City before a
certificate of occupancy is issued. If construction of the irrigation system is
delayed until after construction is completed, a certificate of occupancy can be
issued only with an acceptable bond deposited with the City.
How strict are the standards?
The standards most important to water conservation are mandatory requirements,
identified with the word shall. Other standards are more flexible, they use the phrases
should or to the extent practical. These are enforced on a case -by -case basis.
How do I get copies of the standards?
Pick up copies of the standards for Landscaping and/or Landscape Irrigation Systems at
the Planning Department at 281 N. College or at the Water Utilities at 700 Wood Street.
For more information, or to have copies of the standards mailed to you, call the Water
Utilities at 221-6681.
