See the attached info that the College has received. Perhaps we use this email as the attachment. The college is willing
to commit to moving the trees that will be impacted where possible or replace (if deemed to be in poor health).
Let me know if you think this works

Hi Annie,
2
Sorry it has taken me a few weeks to get back to you! I have been meaning to send you a list of some
guidelines to consider throughout the development review/SPAR process. Regarding what City Forestry will
review on the plans, we typically like to see the following details shown:
- City of Fort Collins General Landscape Notes (optional) and Tree Protection Notes (required) -
attached
- Existing tree locations surveyed and included on a site/landscape plan
- Existing tree inventory table including species, size (caliper inches), condition, mitigation value
(required number of mitigation trees*), and status of tree retention/removal/transplant. Trees are
typically numbered on the plan and a corresponding number is provided in the inventory table.
o *Since this is a SPAR, we will not require you to provide upsized mitigation trees. However,
below I will provide the mitigation sizes in the case that you do wish to upsize replacement
trees. If you would like my help, I am happy to meet on-site again to inventory the trees in
more detail (size, condition, and recommended mitigation value).
Typical upsized mitigation tree sizes:
• Canopy Shade Trees: 3.0” caliper B&B or equivalent
• Evergreen Trees: 8’ height B&B or equivalent
• Ornamental Trees: 2.5” caliper B&B or equivalent
o Tree inventory table should include whether the tree is to remain and be protected, to be
removed, or to be transplanted.
Trees to be removed are typically shown with a X over the symbol.
Transplanted trees are symbolized with a bolded, capital “T” next to the symbol. Our
general transplanting note is also displayed on the landscape plans: Transplanting trees
#__, SPECIES, shall follow the recommendations of a qualified tree transplanting
contractor in terms of size, staking, mulching, and irrigation. If trees are transplanted
back on-site, please provide the transplanting location on the site/landscape plans.
- Proposed Plant List to include quantity, species (scientific and common name), size (caliper inches),
method of transplant (B&B or equivalent), species diversity percentage
o Typical planting sizes for new trees and shrubs:
Canopy Shade Trees: 2.0” caliper B&B or equivalent
Evergreen Trees: 6’ height B&B or equivalent
Ornamental Trees: 1.5” caliper B&B or equivalent
Shrubs: 5 gallon or adequate size consistent with design intent
o Recommended Species list (attached). City Forestry will review trees in the plant list provided
on the landscape plan. The City of Fort Collins recommended plant list is currently under review
– contact Stephanie Blochowiak in Environmental Planning if you have questions on specific
plants/varieties.
o Species Diversity Percentage:
• To prevent uniform insect or disease susceptibility and eventual uniform
senescence on a development site or in the adjacent area or the district, species
diversity is required and extensive monocultures are prohibited. The following
minimum requirements shall apply to any development plan.
Number of trees on site Maximum percentage of any one species
10-19 50%
20-39 33%
40-59 25%
3
60 or more 15%
- Utility/Tree Separation Guidelines
o Include utilities on the site/landscape plan (gas, electric, water, sanitary sewer, storm sewer,
etc). Please consider placement of existing and proposed tree locations to meet the following
separations:
10’ between trees and public water, sanitary, and storm sewer main lines, electric lines
6’ between trees and public water, sanitary, and storm sewer service lines
4’ between trees and gas lines
- Street light/stop sign Separation Guidelines
o Include locations of street lights (probably not proposed on this project) and stop signs on the
site/landscape plan. Please consider placement of existing and proposed tree locations to meet
the following separations:
Stop Signs: 20 feet from sign
Street Light: 40 feet for canopy shade trees and 15 feet for ornamental trees
- Tree Protection Specifications
o Tree Protection will be required around all City owned street trees between the curb and
sidewalk along Shields Street and Horsetooth Road. Please follow the guidelines below. Tree
protection is not required, but is encouraged, around all existing trees to retain on FRCC
property.
(1) Within the drip line of any protected existing tree, there shall be no cut or fill over a four-inch depth
unless a qualified arborist or forester has evaluated and approved the disturbance.
(2) All protected existing trees shall be pruned to the City of Fort Collins Forestry standards.
(3) Prior to and during construction, barriers shall be erected around all protected existing trees with such
barriers to be of orange fencing a minimum of four (4) feet in height, secured with metal T-posts, no
closer than six (6) feet from the trunk or one-half (½) of the drip line, whichever is greater. There shall be
no storage or movement of equipment, material, debris or fill within the fenced tree protection zone.
(4) During the construction stage of development, the applicant shall prevent the cleaning of equipment
or material or the storage and disposal of waste material such as paints, oils, solvents, asphalt, concrete,
motor oil or any other material harmful to the life of a tree within the drip line of any protected tree or
group of trees.
(5) No damaging attachment, wires, signs or permits may be fastened to any protected tree.
(6) Large property areas containing protected trees and separated from construction or land clearing
areas, road rights-of-way and utility easements may be "ribboned off," rather than erecting protective
fencing around each tree as required in subsection (G)(3) above. This may be accomplished by placing
metal t-post stakes a maximum of fifty (50) feet apart and tying ribbon or rope from stake-to-stake along
the outside perimeters of such areas being cleared.
(7) The installation of utilities, irrigation lines or any underground fixture requiring excavation deeper than
six (6) inches shall be accomplished by boring under the root system of protected existing trees at a
minimum depth of twenty-four (24) inches. The auger distance is established from the face of the tree
(outer bark) and is scaled from tree diameter at breast height as described in the chart below.
I am more than happy to provide additional information throughout the SPAR process. Please let me know if you have
any questions!
Have a great weekend!

Plant List
April 2011
April 2011 2 City of Fort Collins Plant List
City of Fort Collins Plant List
This Plant List was developed to meet the provisions of the Land Use Code Section 3.2.1
regarding Landscape Plans that are submitted as part of the development review process.
Landscape Plans are required for commercial, multifamily and common areas of subdivisions, but
do not apply to single-family residences.
The Land Use Code says that plant material for Landscape Plans must be selected from the City
of Fort Collins Plant List. Additional plants may be added to the list upon a determination that
the plants are appropriate for inclusion.
In addition, hydrozones must be shown on the plan. Hydrozones are areas defined by a grouping
of plants requiring a similar amount of water to sustain health. The four hydrozones based on
supplemental irrigation needed:
High Hydrozone (H): 18 gallons/s.f./season
Moderate Hydrozone (M): 10 gallons/s.f./season
Low Hydrozone (L): 3 gallons/s.f./season
Very Low Hydrozone (VL): 0 gallons/s.f./season

DIVISION 3.1 GENERAL PROVISIONS
Sections:
3.1.1 Applicability
3.1.2 Relation to Zone District Standards (Article 4)
3.1.1 Applicability
All development applications and building permit applications shall comply with the
applicable standards contained in Divisions 3.1 through 3.9, except that single-family
dwellings and extra occupancy rental houses that are subject only to basic development
review under Article 4, as well as any accessory buildings, structures and accessory uses
associated with such single-family dwellings and extra occupancy rental houses, need to
comply only with: (A) the standards contained in Article 4 for the zone district in which
such uses are located; (B) the standards contained in Division 3.8; and (C) with respect to
extra occupancy rental houses, the standards contained in Section 3.2.2(K)(1)(j). In
addition to the foregoing, this Land Use Code shall also apply to the use of land
following development to the extent that the provisions of this Land Use Code can be
reasonably and logically interpreted as having such ongoing application.
(Ord. No. 59, 2000 §11, 6/6/00; Ord. No. 204, 2001 §§1, 11, 12/18/01; Ord. No. 120, 2003 §1,
9/2/03; Ord. No. 198, 2004 §3, 12/21/04; Ord. 123, 2005 §3, 11/15/05)
3.1.2 Relation to Zone District Standards (Article 4)
In the event of a conflict between a standard or requirement contained in Article 3 and
Article 4, the standard in Article 4 shall prevail.
DIVISION 3.2 SITE PLANNING AND DESIGN STANDARDS
Sections:
3.2.1 Landscaping and Tree Protection
3.2.2 Access, Circulation and Parking
3.2.3 Solar Access, Orientation, Shading
3.2.4 Site Lighting
3.2.5 Trash and Recycling Enclosures
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 area buffer zones
established according to Section 3.4.1 (Natural Habitats and Features).
(B) Purpose. The intent of this Section is to require preparation of landscape and
tree protection plans that ensure significant canopy shading to reduce glare and
heat build-up, contribute to visual quality and continuity within and between
developments, provide screening and mitigation of potential conflicts between
activity areas and site elements, enhance outdoor spaces, reduce erosion and
stormwater runoff, encourage water conservation and mitigate air pollution.
(C) General Standard. All developments shall submit a landscape and tree
protection 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.
(D) Tree Planting Standards. All developments shall establish groves and belts
of trees along all city streets, in and around parking lots, and in all landscape areas
that are located within fifty (50) feet of any building or structure in order to
establish at least a partial urban tree canopy. 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 Plantings/Description. These tree standards require at least a
minimum tree canopy 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) parking 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) street 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" 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 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) square feet.
Planting cutouts, planters or other landscape areas for tree planting
shall be provided within any walkway that is twelve (12) feet or
greater in width adjoining a vehicle use area that is not covered
with an overhead fixture or canopy that would prevent growth and
maturity.
Full tree stocking 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'
Coniferous evergreens 20'-30'
Ornamental trees 20'-30'
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 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 in connection with the development by one (1) or more of the
methods described in subparagraphs (a) through (c) below:
(a) Wherever the sidewalk is separated from the street by a
parkway, 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) 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
spacing 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) square feet at thirty-foot to forty-foot spacing.
(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 prevent normal growth and maturity.
Ornamental trees shall be placed at least fifteen (15) feet away
from any streetlight.
(3) Minimum Species Diversity. To prevent uniform insect or disease
susceptibility and eventual uniform senescence on a development site or in
the adjacent area or the district, species diversity is required and extensive
monocultures are prohibited. The following minimum requirements shall
apply to any development plan.
Number of trees on site Maximum percentage of any one species
10-19 50%
20-39 33%
40-59 25%
60 or more 15%
(4) Tree Species and Minimum Sizes. The Director shall provide a
recommended list of trees which shall be acceptable to satisfy the
requirements for landscape plans, including approved canopy shade trees
that may be used as street trees. The following minimum sizes shall be
required (except as provided in subparagraph (5) below):
Type Minimum Size
Canopy Shade Tree 2.0" caliper balled and burlapped or equivalent
Evergreen Tree 6.0' height balled and burlapped or equivalent
Ornamental Tree 1.5" caliper balled and burlapped or equivalent
Shrubs 5 gallon or adequate size consistent with design intent
Canopy Shade Tree
as a street tree on a
Residential Local
Street Only
1.25" caliper container or equivalent
Any tree plantings that are in addition to those that are made as part of the
approved landscape plan are exempt from the foregoing size requirements.
(5) Reduced Minimum Sizes for Affordable Housing Projects. In any
affordable housing project, the following minimum sizes shall be required:
Type Minimum Size
Canopy Shade Tree 1.0" caliper container or equivalent
Evergreen Tree 4.0' height container or equivalent
Ornamental Tree 1.0" caliper container or equivalent
Shrubs 1 gallon
Canopy Shade Tree
as a street tree on a
Local or Collector
Street only
1.25" caliper container or equivalent
(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 is 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.
(2) Landscape Area Treatment. Landscape areas shall include all areas on
the site that are not covered by buildings, structures, paving or impervious
surface. Landscape areas shall consist only of landscaping. The selection
and location of turf, ground cover (including shrubs, grasses, perennials,
flowerbeds and slope retention), and pedestrian paving and other
landscaping elements shall be used to prevent erosion and meet the
functional and visual purposes such as defining spaces, accommodating
and directing circulation patterns, managing visibility, attracting attention
to building entrances and other focal points, and visually integrating
buildings with the landscape area and with each other.
(a) Turf grass. High-use areas shall be planted with irrigated turf
grass. Nonirrigated shortgrass prairie grasses or other adapted
grasses that have been certified as Xeriscape landscaping may be
established in remote, low-use, low visibility areas.
(b) Planting beds. Shrub and ground cover planting beds shall be
separated from turf grass with edging and shall have open surface
areas covered with mulch.
(c) Slopes. Retaining walls, slope revetment or other acceptable
devices integrated with plantings shall be used to stabilize slopes
that are steeper than 3:1. If soil tests performed on the subject soils
indicate steeper slopes are stable without the above required
protection, then the maximum slope allowed without the above
required protection may be increased to the maximum stated in the
soils report or 2:1, whichever is less steep.
(d) Foundation Plantings. Exposed sections of building walls that
are in high-use or high-visibility areas of the building exterior shall
have planting beds at least five (5) feet wide placed directly along
at least fifty (50) percent of such walls.
(e) Parkways. All adjoining street parkways shall be landscaped in
connection with the development in accordance with the Larimer
County Urban Area Street Standards.
(f) Agricultural Use. If outdoor space is maintained in active
agricultural use, the landscape surfaces and ground cover standards
above shall not apply.
(3) Water Conservation. To the extent reasonably feasible, all landscape
plans shall be designed to incorporate water conservation materials and
techniques in order to comply with each of the Xeriscape landscaping
principles listed below. Xeriscape landscaping principles do not include or
allow artificial turf or plants, mulched (including gravel) beds or areas
without landscape plant material, paving of areas not required for
walkways, plazas or parking lots, bare ground, weed covered or infested
surfaces or any landscaping that does not comply with the standards of this
section.
(a) Xeriscape landscaping principles are as follows:
1. Design. Identify zones of different water requirements
and group plants together that have similar water needs;
2. Appropriate Use of Turf. Limit high-irrigation turf and
plantings to appropriate high-use areas with high visibility
and functional needs;
3. Low-Water-Using Plants. Choose low-water-demanding
plants and turf where practicable;
4. Irrigation. Design, operate and maintain an efficient
irrigation system;
5. Soil Preparation. Incorporate soil amendments before
planting;
6. Mulch. Add mulch to planting beds to a minimum depth
of three (3) inches;
7. Maintenance. Provide regular and attentive maintenance.
(b) Landscape plans submitted shall include:
1. Accurate and clear identification of all applicable
hydrozones using the following categories:
High Hydrozone: 18 gallons/s.f./season
Moderate Hydrozone: 10 gallons/s.f./season
Low Hydrozone: 3 gallons/s.f./season
Very Low Hydrozone: 0 gallons/s.f./season
2. A water budget chart that shows the total annual water
use, which shall not exceed fifteen (15) gallons/square foot
over the site, including all hydrozones used on the
landscape plan.
(4) Parking Lot Perimeter Landscaping. Parking lot perimeter landscaping
(in the minimum setback areas required by Section 3.2.2(J) (Access,
Circulation and Parking) shall meet the following minimum standards:
(a) Trees shall be provided at a ratio of one (1) tree per twenty-five
(25) lineal feet along a public street and one (1) tree per forty (40)
lineal feet along a side lot line parking setback area. Trees may be
spaced irregularly in informal groupings or be uniformly spaced, as
consistent with larger overall planting patterns and organization.
Perimeter landscaping along a street may be located in and should
be integrated with the streetscape in the street right-of-way.
(b) Screening. Parking lots with six (6) or more spaces shall be
screened from abutting uses and from the street. Screening from
residential uses shall consist of a fence or wall six (6) feet in height
in combination with plant material and of sufficient opacity to
block at least seventy-five (75) percent of light from vehicle
headlights. Screening from the street and all nonresidential uses
shall consist of a wall, fence, planter, earthen berm, plant material
or a combination of such elements, each of which shall have a
minimum height of thirty (30) inches. Such screening shall extend
a minimum of seventy (70) percent of the length of the street
frontage of the parking lot and also seventy (70) percent of the
length of any boundary of the parking lot that abuts any
nonresidential use. Openings in the required screening shall be
permitted for such features as access ways or drainage ways.
Where screening from the street is required, plans submitted for
review shall include a graphic depiction of the parking lot
screening as seen from the street. Plant material used for the
required screening shall achieve required opacity in its winter
seasonal condition within three (3) years of construction of the
vehicular use area to be screened.
(5) Parking Lot Interior Landscaping. As required in Section 3.2.2(M)(1)
Access, Circulation and Parking, six (6) percent of the interior space of all
parking lots with less than one hundred (100) spaces, and ten (10) percent
of the interior space of all parking lots with one hundred (100) spaces or
more shall be landscape areas. (See Figure 1). All parking lot islands,
connecting walkways through parking lots and driveways through or to
parking lots shall be landscaped according to the following standards:
(a) Visibility. To avoid landscape material blocking driver sight
distance at driveway-street intersections, no plant material greater
than twenty-four (24) inches in height shall be located within
fifteen (15) feet of a curbcut.
(b) Maximized Area of Shading. Landscaped islands shall be
evenly distributed to the maximum extent feasible. At a minimum,
trees shall be planted at a ratio of at least one (1) canopy shade tree
per one hundred fifty (150) square feet of internal landscaped area
with a landscaped surface of turf, ground cover perennials or
mulched shrub plantings.
(c) Landscaped Islands. In addition to any pedestrian refuge areas,
each landscaped island shall include one (1) or more canopy shade
trees, be of length greater than eight (8) feet in its smallest
dimension, include at least eighty (80) square feet of ground area
per tree to allow for root aeration, and have raised concrete curbs.

parking lots, as required in subsection 3.2.2(B)(5)(a) (Walkways)
shall have one (1) canopy shade tree per forty (40) lineal feet of
such walkway planted in landscape areas within five (5) feet of
such walkway. Driveways through or to parking lots shall have one
(1) canopy shade tree per forty (40) lineal feet of and along each
side of such driveway, in landscape areas within five (5) feet of
such driveway.
(e) Parking bays shall extend no more than fifteen (15) parking
spaces without an intervening tree, landscape island or landscape
peninsula.
(f) Engineering. Detailed specifications concerning parking lot
surfacing material and parking lot drainage detention are available
from the City Engineer.
(6) Screening. Landscape and building elements shall be used to screen
areas of low visual interest or visually intrusive site elements (such as
trash collection, open storage, service areas, loading docks and blank
walls) from off-site view. Such screening shall be established on all sides
of such elements except where an opening is required for access. If access
is possible only on a side that is visible from a public street, a removable
or operable screen shall be required. The screen shall be designed and
established so that the area or element being screened is no more than
twenty (20) percent visible through the screen.
(a) Screening Materials. Required screening shall be provided in
the form of new or existing plantings, walls, fences, screen panels,
topographic changes, buildings, horizontal separation or a
combination of these techniques.
(7) Landscaping of Vehicle Display Lots. Vehicle display lots for vehicle
sales and leasing (as those terms are defined in Article 5) that abut an
arterial or collector street shall feature landscaped islands along the street
at an interval not to exceed every fifteen (15) vehicles or one hundred
thirty-five (135) feet, whichever is less. Each landscaped island shall
comply with the requirements of Section 3.2.1(E)(5)(c).
(F) Tree Protection and Replacement. Existing significant trees within the LOD
and within natural area buffer zones shall be preserved to the extent reasonably
feasible and may help satisfy the landscaping requirements of this Section as set
forth above. Such trees shall be considered "protected" trees within the meaning
of this Section, subject to the exceptions contained in subsection (2) below.
Streets, buildings and lot layouts shall be designed to minimize the disturbance to
significant existing trees. All required landscape plans shall accurately identify
the locations, species, size and condition of all significant trees, each labeled
showing the applicant’s intent to either remove, transplant or protect.
Where it is not feasible to protect and retain significant existing tree(s) or to
transplant them to another on-site location, the applicant shall replace such tree(s)
according to the following schedule and requirements. Replacement trees shall be
used to satisfy the tree planting standards of this Section. Replacement trees shall
be planted either on the development site or in the closest available and suitable
planting site. The closest available and suitable planting site shall be selected
within one-half (½) mile (2,640 feet) of the development site, subject to the
following exceptions. If suitable planting sites for all of the mitigation trees are
not available within one-half (½) mile (2,640 feet) of the development, then the
planting site shall be selected within one (1) mile (5,280 feet) of the development
site. If suitable planting sites are not available for all of the mitigation trees within
one (1) mile (5,280 feet) of the development site, then the City Forester shall
determine the most suitable planting location within the City's boundaries as close
to the development site as feasible.
(1) A significant tree that is removed shall be replaced with not less than
one (1) or more than six (6) replacement trees sufficient to mitigate the
loss of value of the removed significant tree. Notwithstanding the
foregoing, significant Siberian elm and Russian olive trees located in a
natural habitat buffer found to contain ecological value, as provided in
paragraph 3.4.1(D)(1) of this Code, shall be mitigated in accordance with
subparagraph 3.4.1(E)(2)(b) of this Code. The applicant shall select either
the City Forester or a qualified landscape appraiser to determine such loss
based upon an appraisal, including, but not limited to, shade, canopy,
aesthetic, environmental and ecological value of the tree to be removed
and by using the species and location criteria in the most recent published
appraisal guide by the Council of Tree and Landscape Appraisers.
Replacement trees shall meet the following minimum size requirements:
(a) Canopy Shade Trees: 3.0" caliper balled and burlap or
equivalent.
(b) Ornamental Trees: 2.5" caliper balled and burlap or equivalent.
(c) Evergreen Trees: 8' height balled and burlap or equivalent.
(2) Trees that meet one (1) or more of the following removal criteria shall
be exempt from the requirements of this subsection:
(a) dead, dying or naturally fallen trees, or trees found to be a
threat to public health, safety or welfare;
(b) trees that are determined by the City to substantially obstruct
clear visibility at driveways and intersections;
(c) Siberian elm less than eleven (11) inches DBH and Russian
olive less than eight (8) inches DBH;
(d) Russian olive and Siberian elm of wild or volunteer origin,
such as those that have sprouted from seed along fence lines, near
structures or in other unsuitable locations;
(e) Russian olive and Siberian elm determined by the City Forester
to be in poor condition.
(3) All existing street trees that are located on city rights-of-way abutting
the development shall be accurately identified by species, size, location
and condition on required landscape plans, and shall be preserved and
protected in accordance with the standards of subsection (G).
(G) Tree Protection Specifications. The following tree protection specifications
should be followed to the maximum extent feasible for all projects with protected
existing trees.
(1) Within the drip line of any protected existing tree, there shall be no cut
or fill over a four-inch depth unless a qualified arborist or forester has
evaluated and approved the disturbance.
(2) All protected existing trees shall be pruned to the City of Fort Collins
Forestry standards.
(3) Prior to and during construction, barriers shall be erected around all
protected existing trees with such barriers to be of orange fencing a
minimum of four (4) feet in height, secured with metal T-posts, no closer
than six (6) feet from the trunk or one-half (½) of the drip line, whichever
is greater. There shall be no storage or movement of equipment, material,
debris or fill within the fenced tree protection zone.
(4) During the construction stage of development, the applicant shall
prevent the cleaning of equipment or material or the storage and disposal
of waste material such as paints, oils, solvents, asphalt, concrete, motor oil
or any other material harmful to the life of a tree within the drip line of
any protected tree or group of trees.
(5) No damaging attachment, wires, signs or permits may be fastened to
any protected tree.
(6) Large property areas containing protected trees and separated from
construction or land clearing areas, road rights-of-way and utility
easements may be "ribboned off," rather than erecting protective fencing
around each tree as required in subsection (G)(3) above. This may be
accomplished by placing metal t-post stakes a maximum of fifty (50) feet
apart and tying ribbon or rope from stake-to-stake along the outside
perimeters of such areas being cleared.
(7) The installation of utilities, irrigation lines or any underground fixture
requiring excavation deeper than six (6) inches shall be accomplished by
boring under the root system of protected existing trees at a minimum
depth of twenty-four (24) inches. The auger distance is established from
the face of the tree (outer bark) and is scaled from tree diameter at breast
height as described in the chart below.

(H) Placement and Interrelationship of Required Landscape Plan Elements. In
approving the required landscape plan, the decision maker shall have the authority
to determine the optimum placement and interrelationship of required landscape
plan elements such as trees, vegetation, turf, irrigation, screening, buffering and
fencing, based on the following criteria:
(1) protecting existing trees, natural areas and features;
(2) enhancing visual continuity within and between neighborhoods;
(3) providing tree canopy cover;
(4) creating visual interest year round;
(5) complementing the architecture of a development;
(6) providing screening of areas of low visual interest or visually intrusive
site elements;
(7) establishing an urban context within mixed-use developments;
(8) providing privacy to residents and users;
(9) conserving water;
(10) avoiding reliance on excessive maintenance;
(11) promoting compatibility and buffering between and among dissimilar
land uses;
(12) establishing spatial definition.
(I) Landscape Materials, Maintenance and Replacement.
(1) Topsoil. To the maximum extent feasible, topsoil that is removed
during construction activity shall be conserved for later use on areas
requiring revegetation and landscaping. Organic soil amendments shall
also be incorporated in accordance with the requirements of Section
3.8.21.
(2) Plant Materials. Plant materials shall be selected from a list of native
plants and other plants determined to be appropriate for and well adapted
to local environmental conditions, as such list is established and updated
from time to time by the Director and entitled the City of Fort Collins
Plant List. Additional plants may be added to the Plant List upon a
determination by the Director that such plants are appropriate for inclusion
consistent with the above standard.
(3) Plant Quality. All plants shall be A-Grade or No. 1 Grade, free of any
defects, of normal health, height, leaf density and spread appropriate to the
species as defined by American Association of Nurserymen standards.
(4) Installation. All landscaping shall be installed according to sound
horticultural practices in a manner designed to encourage quick
establishment and healthy growth. All landscaping in each phase shall
either be installed or the installation shall be secured with a letter of credit,
escrow or performance bond for one hundred twenty-five (125) percent of
the value of the landscaping prior to the issuance of a certificate of
occupancy for any building in such phase.
(5) Maintenance. Trees and vegetation, irrigation systems, fences, walls
and other landscape elements shall be considered as elements of the
project in the same manner as parking, building materials and other site
details. The applicant, landowner or successors in interest shall be jointly
and severally responsible for the regular maintenance of all landscaping
elements in good condition. All landscaping shall be maintained free from
disease, pests, weeds and litter, and all landscape structures such as fences
and walls shall be repaired and replaced periodically to maintain a
structurally sound condition.
(6) Replacement. Any landscape element that dies, or is otherwise
removed, shall be promptly replaced based on the requirements of this
Section.
(7) Mitigation. Healthy, mature trees that are removed by the applicant or
by anyone acting on behalf of or with the approval of the applicant shall
be replaced with not less than one (1) or more than six (6) replacement
trees sufficient to mitigate the loss of value of the removed tree. The
applicant shall select either the City Forester or a qualified landscape
appraiser to determine such loss based upon an appraisal of the removed
tree, using the most recent published methods established by the Council
of Tree and Landscape Appraisers. Larger than minimum sizes (as set
forth in subsection (D)(4) above) shall be required for such replacement
trees.
(J) Irrigation.
(1) Provision shall be made for permanent, automatic irrigation of all plant
material, with the following exceptions:
(a) very low-water-use plantings that do not require any
supplemental irrigation beyond establishment.
(b) trees and other plants used to landscape a residential local street
parkway abutting lots for single-family detached dwellings.
(2) For any development provided water by the City, an irrigation plan
shall be submitted to and approved by the Utilities Executive Director
prior to the issuance of the building permit, or if no building permit is
required, then prior to commencement of construction. As determined by
the Director, minor redevelopment or change of use projects may not be
required to submit an irrigation plan; in such cases, a written statement
shall be submitted describing the type of irrigation system proposed. The
irrigation plan shall incorporate the City of Fort Collins Irrigation System
Standards for Water Conservation set forth below. In addition, the
irrigation system must be inspected for compliance with the approved
irrigation plan before the issuance of a Certificate of Occupancy.
(3) The City of Fort Collins Irrigation System Standards for Water
Conservation are as follows:
(a) Irrigation Methods and Layout.
1. The irrigation system shall be designed according to the
hydrozones shown on the landscape plan.
2. Each zone shall irrigate a landscape with similar site, soil
conditions and plant material having similar water needs.
To the extent reasonably feasible, areas with significantly
different solar exposures shall be zoned separately.
3. Turf and non-turf areas shall be irrigated on separate
zones.
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. Drip, micro-sprays, sprayheads and rotors shall not be
combined on the same zone.
6. The irrigation method shall be selected to correlate with
the plant density. Drip irrigation or bubblers shall be used
for sparsely planted trees and shrubs, and rotors,
sprayheads and multi-jet rotary nozzles shall be used for
turfgrass.
(b) Equipment Selection.
1. In order to reduce leakage of water from the irrigation
system, a master shut-off valve shall be installed
downstream of the backflow device to shut off water to the
system when not operating.
2. For irrigation systems that are on a combined-use tap,
with a water meter installed upstream to measure total
water use, the installation of an irrigation-only submeter
should be considered. The purpose of the submeter would
be to enable the owner and landscape maintenance
contractor to monitor water use for irrigation. The submeter
would not be used for billing purposes. The cost of
installation and maintenance of a submeter, if used, would
be borne by the owner of the property and not by the City.
All such submeters would have to be installed in
accordance with the specifications established by the City.
3. Irrigation controllers shall be "smart" controllers, using
climate-based or soil moisture-based technology, selected
from the Irrigation Association's current Smart Water
Application Technologies (SWAT) tested products list or
other similarly tested product list. Controllers shall be
installed and programmed according to manufacturer's
specifications.
a. A data input chart for the Smart Controller,
including the precipitation rate from the audit, shall
be posted at each irrigation controller.
b. Within six (6) weeks of the installation of new
landscaping, the irrigation system Smart Controllers
shall be reset to the normal seasonal watering
schedule.
4. A rain sensor shall be installed on each irrigation
controller and installed according to the manufacturer's
specifications.
5. Sprinklers and nozzles shall meet the following
requirements:
a. The type of sprinkler and associated nozzles shall
be selected to correlate with the size and geometry
of the zone being irrigated.
b. Sprinklers shall be spaced no closer than seventy-
five (75) percent of the maximum radius of throw
for the given sprinkler and nozzle. Maximum
spacing shall be head-to-head coverage.
c. Coverage arcs and radius of throw for turf areas
shall be selected and adjusted to water only turf
areas and minimize overspray onto vegetated areas,
hard surfaces, buildings, fences or other non-
landscaped surfaces.
d. Sprinklers, bubblers or emitters on a zone shall
be of the same manufacturer.
e. Sprayheads in turf areas shall have a minimum
three-and-one-half-inch pop-up riser height.
f. Sprayheads on a zone shall have matched
precipitation nozzles.
g. Nozzles for rotors shall be selected to achieve an
approximate uniform precipitation rate throughout
the zone.
h. All sprayheads and rotors shall be equipped with
check valves. Sprayheads shall also have pressure-
regulating stems.
6. Pressure-compensating emitters shall be used for drip
irrigation. For sloped areas, a check valve shall be installed,
and the drip line shall be parallel to the slope.
7. Remote control valves shall have flow control.
8. A backflow prevention assembly shall be installed in
accordance with local codes. All backflow assemblies shall
be equipped with adequately sized winterization ports
downstream of the backflow assembly.
9. Properties with single or combined point of connection
flows of two hundred (200) gpm or greater shall have a
control system capable of providing real-time flow
monitoring and the ability to shut down the system in the
event of a high-flow condition.
(c) Sleeving.
1. Separate sleeves shall be installed beneath paved areas to
route each run of irrigation pipe or wiring bundle. The
diameter of sleeving shall be twice that of the pipe or
wiring bundle.
2. The sleeving material beneath sidewalks, drives and
streets shall be PVC Class 200 pipe with solvent welded
joints.
(d) Water Pressure.
1. The irrigation system designer shall verify the existing
available water pressure.
2. The irrigation system shall be designed such that the
point-of-connection design pressure, minus the possible
system pressure losses, is greater than or equal to the
design sprinkler operating pressure.
3. All pop-up spray sprinkler bodies equipped with spray
nozzles shall operate at no less than twenty (20) psi and no
more than thirty (30) psi.
4. All rotary sprinklers and multi-stream rotary nozzles on
pop-up spray bodies shall operate at the manufacturer's
specified optimum performance pressure.
5. If the operating pressure exceeds the manufacturer's
specified maximum operating pressure for any sprinkler
body, pressure shall be regulated at the zone valve or
sprinkler heads.
6. Booster pumps shall be installed on systems where
supply pressure does not meet the manufacturer's minimum
recommended operating pressure for efficient water
distribution.
(e) Sprinkler Performance Audit.
1. A sprinkler performance audit shall be performed by a
landscape irrigation auditor who is independent of the
installation contractor, and who is certified by the Irrigation
Association (a nonprofit industry organization dedicated to
promoting efficient irrigation). Sprinkler systems that are
designed and installed without turf areas are exempt from
this requirement.
2. The audit shall include measurement of distribution
uniformity. Minimum acceptable distribution uniformities
shall be sixty (60) percent for sprayhead zones and seventy
(70) percent for rotor zones. Sprinkler heads equipped with
multi-stream rotary nozzles are considered rotors.
3. The audit shall measure the operating pressure for one
(1) sprinkler on each zone to determine whether the zone
meets the above pressure requirements.
4. A copy of the sprinkler performance audit shall be
submitted to and approved by the City before issuance of a
certificate of occupancy.
(K) Utilities and Traffic. Landscape, utility and traffic plans shall be coordinated.
The following list sets forth minimum dimension requirements for the most
common tree/utility and traffic control device separations. Exceptions to these
requirements may occur where utilities or traffic control devices are not located in
their standard designated locations, as approved by the Director. Tree/utility and
traffic control device separations shall not be used as a means of avoiding the
planting of required street trees.
(1) Forty (40) feet between shade trees and streetlights. Fifteen (15) feet
between ornamental trees and streetlights. (See Figure 2.)
Figure 2
Tree/Streetlight Separations
(2) Twenty (20) feet between shade and/or ornamental trees and traffic
control signs and devices.
(3) Ten (10) feet between trees and water or sewer mains.
(4) Six (6) feet between trees and water or sewer service lines.
(5) Four (4) feet between trees and gas lines.
(6) Street trees on local streets planted within the eight-foot-wide utility
easement may conflict with utilities. Additional conduit may be required
to protect underground electric lines.
(L) Visual Clearance or Sight Distance Triangle. Except as provided in
Subparagraphs (1) and (2) below, a visual clearance triangle, free of any
structures or landscape elements over twenty-four (24) inches in height, shall be
maintained at street intersections and driveways in conformance with the
standards contained in the Larimer County Urban Area Street Standards.
(1) Fences shall not exceed forty-two (42) inches in height and shall be of
an open design.
(2) Deciduous trees may be permitted to encroach into the clearance
triangle provided that the lowest branch of any such tree shall be at least
six (6) feet from grade.
(M) Revegetation. When the development causes any disturbance within any
natural area buffer zone, revegetation shall occur as required in paragraph
3.4.1(E)(2) (Development Activities Within the Buffer Zone) and subsection
3.2.1(F) (Tree Protection and Replacement).
(N) Alternative Compliance. Upon request by an applicant, the decision maker
may approve an alternative landscape and tree protection plan that may be
substituted in whole or in part for a landscape plan meeting the standards of this
Section.
(1) Procedure. Alternative landscape plans shall be prepared and
submitted in accordance with submittal requirements for landscape plans.
Each such plan shall clearly identify and discuss the modifications and
alternatives proposed and the ways in which the plan will better
accomplish the purposes of this Section than would a plan which complies
with the standards of this Section.
(2) Review Criteria. To approve an alternative plan, the decision maker
must first find that the proposed alternative plan accomplishes the
purposes of this Section equally well or better than would a plan which
complies with the standards of this Section.
In reviewing the proposed alternative plan for purposes of determining
whether it accomplishes the purposes of this Section as required above, the
decision maker shall take into account whether the alternative preserves
and incorporates existing vegetation in excess of minimum standards,
protects natural areas and features, maximizes tree canopy cover, enhances
neighborhood continuity and connectivity, fosters nonvehicular access, or
demonstrates innovative design and use of plant materials and other
landscape elements.
