OF THE COUNCIL OF THE CITY OF FORT COLLINS
AMENDING CHAPTER 26 OF THE CODE OF THE CITY OF FORT COLLINS
TO IMPOSE CERTAIN LIMITATIONS ON WHEN AND HOW WATER OBTAINED
FROM THE CITY MAY BE USED TO IRRIGATE OUTSIDE VEGETATION
WHEREAS, the City owns and operates Fort Collins Utilities (“Utilities”), which
includes a water utility that provides water to customers in its service area; and
WHEREAS, water conservation and efficiency is a tool Utilities uses, primarily
through the Utilities Water Conservation Division, to manage and reduce the demand for
water service by Utilities customers, which is beneficial to the City, the water utility, and
its ratepayers by, among other reasons, reducing demand on water supplies and helping to
ensure that the demand for water does not exceed supplies; and
WHEREAS, evaporation rates are at their highest during the middle of the day and
in the summer months, such that irrigation of outdoor vegetation is less efficient during
those periods, resulting in a larger use of water for the same benefit; and
WHEREAS, limiting various types and uses of irrigation by ratepayers during those
periods, as a water conservation and efficiency measure, will help Utilities manage and
reduce the demand on water supplies and helping to ensure that the demand for water does
not exceed supplies;
NOW, THEREFORE, BE IT ORDAINED BY THE COUNCIL OF THE CITY OF
FORT COLLINS as follows:
Section 1. That the City Council hereby makes and adopts the determinations
and findings contained in the recitals set forth above.
Section 2. That Section 26-166 of the Code of the City of Fort Collins is
hereby amended by the addition of a new Subsection (d) which reads in its entirety as

Division 3.2 – Site Planning and Design Standards
3.2.1 Landscaping and Tree Protection
(A) Applicability. This Section shall apply to all development (except for development on existing lots for single-
family detached dwellings) within the designated "limits of development" ("LOD") and natural habitat buffer
zones (NHBZs) established according to Section 3.4.1 (Natural Habitats and Features), except applicability of
this Section to development on existing lots for single family detached dwellings is as provided in Section
3.1.1 (Applicability) and Division 3.8 (Supplementary Regulations).
(B) Purpose. The intent of this Section is to require preparation of landscape and tree protection plans that
increase tree survival rates; protect, expand, and maintain a diverse ensure significant canopy cover is
created, diversified and maintained infrastructure; reduce unauthorized removal of trees before, during, and
after construction; support and prioritize a thriving natural habitats and features; and conserve water so that
all associated social and environmental benefits are maximized to the extent reasonably feasible. These
benefits include reduced erosion and stormwater runoff, improved water conservation, air pollution
mitigation, reduced glare and heat build-up, increased aesthetics, and improved continuity within and
between developments. Trees planted in appropriate spaces also provide screening and may mitigate
potential conflicts between activity areas and other site elements while enhancing outdoor spaces, all of
which add to a more resilient urban forest.
(C) General Standard. All developments shall submit a landscape and tree protection plan (hereinafter
“landscape plan”), and, if receiving water service from the City, an irrigation plan, that: (1) reinforces and
extends any existing patterns of outdoor spaces and vegetation where practicable;, (2) supports functional
purposes such as spatial definition, visual screening, creation of privacy, management of microclimate or
drainage;, (3) enhances the appearance of the development and neighborhood ;, (4) protects significant
trees, natural systems and habitat;, (5) enhances the pedestrian environment;, (6) identifies all landscape
areas;, (7) identifies all landscaping elements within each landscape area;, and (8) meets or exceeds the
standards of this Section. Notwithstanding the issuance of an occupancy permit under Subsections 3.2.1(I)(4)
or (J)(2) or 3.2.2(M)(2) or (3), subsequent to issuance of the occupancy permit, any redevelopment where
more than thirty-five percent (35%) of the landscape area is affected shall submit a landscape plan for the
area proposed to be redeveloped within the existing landscape plan, and if applicable an irrigation plan for
the redevelopment.
(D) Tree Planting Standards. All developments shall establish groves of trees, and belts of trees, or both, along
all city streets, in and around parking lots, and in all landscape areas of any development, building or
structure. that are located within fifty (50) feet of any building or structure in order The standard is meant to
establish useful at least a partial urban tree canopy in available and appropriate spaces. The groves and belts
may also be combined or interspersed with other landscape areas in remaining portions of the development
to accommodate views and functions such as active recreation and storm drainage.
(1) Minimum Tree Stocking RequirementsPlantings/Description. These tree standards outline the required
at least a minimum tree canopy and are in addition to requirements for preserving existing trees,
parking lot landscape requirements and required tree mitigation. These stocking requirements but are
not intended to limit additional tree plantings in any remaining portions of the development. Groves
and belts of trees shall be required as follows:
(a) pParking lot landscaping in accordance with the parking lot landscaping standards as set forth in
this Section and in Section 3.2.2. Access, Circulation and Parking;

(b) sStreet tree planting in accordance with the Larimer County Urban Area Street Standards or other
street tree planting as defined in subsection (2)(b) or (c) below;
(c) "full tree stocking"Trees shall be required in all landscape areas within fifty (50) feet of any
building or structure as further described below. Landscape areas shall be provided in adequate
numbers, locations and dimensions to allow full tree stocking to occur along all areas of high use
or high visibility sides of any building or structure. Such landscape areas shall extend at least
seven (7) feet from any building or structure wall and contain at least fifty -five (55) square feet of
nonpaved ground area, except that any planting cutouts in walkways shall contain at least sixteen
(16)thirty-two (32) square feet, except in the Downtown District where tree cutouts shall mimic
or exceed existing design or character to adjacent Street Frontage Types as outlined in Division
4.16. Planting cutouts, planters or other landscape areas for tree planting shall be provided
within any walkway that is twelve (12)ten (10) feet or greater in width adjoining a vehicle use
area that is not covered with an overhead fixture or canopy that would prev ent growth and
maturity.
Full tree stocking under this paragraph shall mean formal or informal groupings of trees
planted according to the following spacing dimensions:
Tree Type Minimum/Maximum Spacing
Canopy shade trees 30'—40' spacing
Coniferous evergreens 20'—40' spacing
Ornamental trees 20'—40' spacing
Exact locations and spacings may be adjusted at the option of the applicant to support
patterns of use, views and circulation as long as the minimum tree planting requirement is
met. Canopy shade trees shall constitute at least fifty (50) percent (50%) of all tree
plantings. Trees required in subparagraphs (a) or (b) above may be used to contribute to
this standard.
(2) Street Trees. Planting of street trees shall occur in the adjoining street right-of-way, after first obtaining
a street tree permit (free of charge) from the Forestry Division as stated in the Fort Collins Municipal
Code Article 3, Sec 27-31., eExcept as described in subparagraph (b) below, the street tree plantings in
connection with the development shall occur by one (1) or more of the methods described in
subparagraphs (a) through (d) below:
(a) Wherever the sidewalk is separated from the street by a parkway, with a minimum width of eight
(8) feet in compliance with Larimer County Urban Area Street Standards, canopy shade trees shall
be planted at thirty-foot to forty foot spacing (averaged along the entire front and sides of the
block face) in the center of all such parkway areas. If two (2) or more consecutive residential lots
along a street each measure between forty (40) and sixty (60) feet in street frontage width, one
(1) tree per lot may be substituted for the thirty-foot to forty foot spacing requirement. Such
street trees shall be placed at least eight (8)four (4) feet away from the edges of driveways and
alleys, and forty (40) feet away from any streetlight and to the extent reasonably feasible, be
positioned at evenly spaced intervals.
(b) Wherever the sidewalk is attached to the street in a manner that fails to comply with the Larimer
County Urban Area Street Standards, canopy shade trees shall be established in an area ranging
from three (3) to seven (7) feet behind the sidewalk at the spa cing intervals as required in
subsection (a) above. Wherever the sidewalk is attached to the street and is ten (10) feet or more
in width, or extends from the curb to the property line, canopy shade trees shall be established in
planting cutout areas of at least sixteen (16)thirty-two (32) square feet at thirty-foot to forty foot

spacing, except in the Downtown District where tree cutouts shall mimic or exceed existing
design or character to adjacent Street Frontage Types as outlined in Division 4.16.
(c) Ornamental trees shall be planted in substitution for the canopy shade trees required in
subsection (D)(2)(a) and (b) above where overhead lines, and fixtures and underground utilities
may prevent normal growth and maturity. Ornamental trees shall be placed at least fifteen (15)
feet away from any streetlight.
(d) Wherever existing ash trees (Fraxinus species) are in the adjoining street right-of-way, the
applicant shall coordinate and obtain an onsite analysis with the City Forester to determine
replacement canopy shade trees either through shadow planting or other emerald ash borer
mitigation methods. The City Forester is available to recommend emerald ash borer mitigation
methods for existing ash trees on private property.
(e) In any multi-phase development plan, all street trees per phase shall be planted as near in time
with one another as feasible and after the irrigation is functioning and the right-of-way turf grass,
if present, is established. The City Forester, through conversations with the landscape contractor
and Developer, shall make the final decision as to what timing is feasible. Street trees shall only
be planted during shoulder seasons, March through June, and September through November, to
avoid the hottest and coldest periods of the year.
(f) Canopy Establishment Escrow. Twenty-five percent (25%) of the cost of all street trees to be
planted within the LOD shall be posted before issuance of the Development Construction Permit
and is separate from development landscape or irrigation escrows. The fair market value fee per
tree is determined by the City Forester or a qualified landscape appraiser using the current
editions of the Council of Tree and Landscape Appraisers’ Guide for Plant Appraisal, the
industry’s international standard and best practice.
(g) The establishment period of three full growing seasons (March through November) begins once
all street trees in a development plan phase have been permitted and planting has been
approved by City of Fort Collins Forestry Division. Within this establishment period, the Applicant
or Developer is responsible for replacing dead, dying or damaged street trees as identified by the
Forestry Division during semi-annual spring and fall inspections. When ninety percent (90%) of
the street trees are established and in a healthy and growing condition after the end of the
establishment period, the Forestry Division will assume maintenance responsibility of the street
trees and use the amount of Canopy Establishment Escrow that is needed to replace any
remaining dead, dying, or damaged street trees and then release any remaining Canopy
Establishment Escrow back to the applicant.
(3) Minimum Species Diversity. To prevent uniform insect or disease susceptibility and eventual uniform
senescence on a development site within the LOD or in the adjacent area or the district, species
diversity is required, and extensive monocultures are prohibited. No more than three (3) consecutive
trees of the same cultivar or variety shall be planted in a row, including corners and groupings. The
following minimum requirements shall apply to any development plan.
Number of trees on site Maximum percentage of any one species

(E) Landscape Standards. All development applications shall include landscape plans that meet the following
minimum standards:
(1) Buffering Between Incompatible Uses and Activities. In situations where the Director determines that
the arrangement of uses or design of buildings does not adequately mitigate conflicts reasonably
anticipated to exist between dissimilar uses, site elements or building designs, one (1) or more of the
following landscape buffering techniques shall be used to mitigate the conflicts.
(a) Separation and screening with plant material: planting dense stands of evergreen trees, canopy
shade trees, ornamental trees or shrubs;
(b) Integration with plantings: incorporating trees, vines, planters or other plantings into the
architectural theme of buildings and their outdoor spaces to subdue differences in architecture
and bulk and avoid harsh edges;
(c) Establishing privacy: establishing vertical landscape elements to screen views into or between
windows and defined outdoor spaces where privacy i s important, such as where larger buildings
are proposed next to side or rear yards of smaller buildings;
(d) Visual integration of fences or walls: providing plant material in conjunction with a screen panel,
arbor, garden wall, privacy fence or security fence to avoid the visual effect created by
unattractive screening or security fences;
(e) Landform shaping: utilizing berming or other grade changes to alter views, subdue sound, change
the sense of proximity and channel pedestrian movement.

having similar water needs. To the extent reasonably feasible, areas with sign ificantly
different solar exposures shall be zoned separately.
3. Trees, including street trees, tTurf and non-turf areas shall be irrigated on separate zones.
Dedicated non-overhead, surface or subsurface irrigation shall be installed for all new trees
and existing trees within the LOD.
4. On steep grades, an irrigation method with a lower precipitation rate shall be used in order
to minimize runoff, and, to the extent reasonably feasible, these areas shall be zoned
separately.
5. No combination of dDrip, micro-sprays, sprayheads and or rotors shall be used together or
not be combined on the same zone.
6. The irrigation method shall be selected to correlate with the plant density. Drip irrigation or
