RE: Ecological Characterization Study (ECS) Report for the Salud Family Health Center Project at the Former
Forney Industries Site, 1830 West Laporte Avenue
Thomas:
This letter report documents the evaluation of habitat conditions at the proposed Salud Family Health Center
(Salud) development parcel. The report was prepared in accordance with Section 3.4.1 of the Land Use Code
of the City of Fort Collins regarding the preparation of an Ecological Characterization Study (ECS) Report. The
proposed development site is located at the former Forney Industries property at 1830 West Larporte Avenue,
Fort Collins, Colorado. The property location is shown on Figure 1.
The property addressed by this ECS report includes the entire 21.4-acre parcel formerly owned by Forney
Industries. The proposed Salud Family Health Center would occur in Lots 1, 2, 4, which comprise 11.6 acres of
the 21.4-acre parcel. The current development proposal calls for the construction of commercial buildings,
roadways, parking areas and other supporting infrastructure.
Ecological characteristics of the property were reviewed during a field survey completed on August 19, 2015.
The field survey was conducted to characterize existing wildlife habitats, as well as to identify any unique or
sensitive natural resource features. The field survey did not include a delineation of wetland boundaries within
the Larimer County Canal No. 2 since no changes are proposed for this irrigation feature. Natural Resources
Conservation Service soils mapping was reviewed, however, to determine if any known hydric (wetland) soil
mapping units are located on the property. Observations recorded during the field evaluation included: major
vegetation communities / wildlife habitats present within the property; dominant vegetation associated with each
community / habitat; unique habitat features; and observations of wildlife species and/or definitive sign.
Photographs showing representative views of existing habitats were also taken to document site conditions.
Wildlife presence and habitat use was based on on-site observations and habitat presence in conjunction with
the known habitat requirements of potential wildlife species. Existing habitats were also evaluated regarding
their ability to support populations of threatened, endangered, and other sensitive plant and wildlife species.
The following provides a summary of information required by Fort Collins Land Use Code under 3.4.1 (D) (1)
items (a) through (k).
ECOLOGICAL STUDY CHARACTERIZATION CHECKLIST
(a & i) Five habitat/land use types were identified within the Salud project area. These were Developed,
Grass/Alfalfa Hayfield, Non-native Grassland/Weedy, Riparian/Larimer County Canal No. 2, and Upland
Woodland (see Figure 1). In addition, there are a number of tree groupings supported within each of these
habitat/land use areas (see Figure 1).
Grass/Alfalfa Hayfield. This is the largest undeveloped habitat in the Salud project area. This area was
historically converted from native grassland to non-native grass/hayfield and is managed and mowed for hay
production. As a result this area has low ecological value and supports no natural habitat features. Dominant

vegetation species supported in this habitat are smooth brome (Bromus inermis)1 and alfalfa (Medicago sativa).
A variety of annual weeds are also present, with field bindweed (Convolvulus arvensis) and common dandelion
(Taraxacum officinale) being the most prevalent. Woody species are restricted to a few Siberian elms (Ulmus
pumila) along the fenceline boundary since current management practices preclude the establishment of shrubs
or trees in mowed hayfield areas. More diverse woodlands are supported in the adjacent Upland Woodland and
Riparian/Larimer Canal No. 2 habitat parcels. Photos 1 and 2 provide representative views of Grass/Alfalfa
Hayfield and surrounding tree stands.
Although Grass/Alfalfa Hayfield represents undeveloped open space for wildlife, seasonal mowing and a lack of
woody vegetation cover limits its value as wildlife habitat. Vegetation cover and food sources are present
primarily on a short-term basis due to mowing and occasional cultivation. The primary value of Grass/Alfalfa
Hayfield as wildlife habitat is that it contributes seasonal food sources for small mammals and avian species
during the growing season prior to mowing. Mule deer and white-tailed deer also may occasionally forage in
hayfield habitats when areas of adjacent suitable cover are available. Mice, voles, and pocket gophers as well
as songbirds such as western meadowlark and horned lark are the only species likely to establish resident
populations in hayfields and weedy edge areas. Songbirds including Brewer’s blackbird, common grackle, and
black-billed magpie also occasionally use Grass/Alfalfa Hayfield habitat. Open-country raptors such as red-
tailed hawk, Swainson’s hawk, American kestrel, northern harrier, and great horned owl as well as mammalian
predators like coyote, striped skunk, and red fox sporadically hunt alfalfa hayfield habitats as well. Canada
geese and mule deer may also occasionally graze in this habitat. There was no evidence of prairie dogs or
prairie dog burrows observed on the property.
Non-native Grassland/Weedy. There are two types of Non-native Grassland/Weedy habitat within the Salud
project area, mowed and un-mowed. Mowed areas are located within the developed portions of the property,
while un-mowed areas exist outside of existing development. Both types have developed after the conversion of
native grassland to areas dominated by non-native grasses and a variety of weedy species. Dominant grasses
include smooth brome, crested wheatgrass (Agropyron cristatum), and Kentucky bluegrass (Poa pratensis).
Common weed species recorded throughout both the mowed and un-mowed areas included field bindweed,
kochia (Bassia scoparia), prickly lettuce (Lactuca serriola), prostrate knotweed (Polygonum aviculare), leafy
spurge (Euphorbia esula), cheatgrass (Bromus tectorum), Canada thistle (Cirsium arvense), curlycup gumweed
(Grindelia squarrosa), common mallow (Malva neglecta), common dandelion, pitseed goosefoot (Chenopodium
berlandieri), and horseweed (Conyza canadensis). Minor amounts of alfalfa are also present in the un-mowed
areas. Photo 3 provides a view of un-mowed Non-native Grassland/Weedy Habitat, and Photo 4 shows mowed
Non-native Grassland/Weedy Habitat.
Habitat value and wildlife use of Non-native Grassland/Weedy varies between the mowed and un-mowed areas.
Mowed areas within the building sites have essentially no habitat value because of adjacent development and
consistent mowing that removes any vegetation cover. Wildlife use of the un-mowed stands is similar to that
described for Grass/Alfalfa Hayfield, except the lack of seasonal mowing results in additional vegetation cover
and may result in more consistent use by species listed for Grass/Alfalfa Hayfield.
Riparian/Larimer County Canal No. 2, Upland Woodland and Tree Stands. As indicated on Figure 1, there
are a number of areas supporting trees in the Salud project area. Each tree group is identified on Figure 1 by
letter designations that correspond to the tree group descriptions in Table 1. Many of the trees are 6 inches in
diameter or larger and may be classified by the City Forester as significant based on the Fort Collins Land Use
Code. The City Forester or a private arborist will need to evaluate the health of these trees in order for their
significance status to be determined. Two views of Riparian/Larimer County Canal No. 2 habitat are provided by
Photos 5 and 6. Photo 1 provides a view of the north side of Tree Groups A and C and Photo 3 provides a view

K.
The Riparian/Larimer County Canal No. 2 and connected Upland Woodland habitat areas (Tree Groups A, D,
and E) create a continuous woodland riparian corridor associated with the Larimer County Canal No. 2. The
Upland Woodland habitat parcel (Tree Group C) essentially creates an extension of riparian habitat into an
upland area not supported by the Larimer County Canal No. 2. In the understory within these tree groupings,
shrubs such as American plum, common buckthorn, and chokecherry (Prunus virginiana) provide additional
habitat diversity, cover, and food sources for wildlife. Other tree stands listed in Table 1 also provide nesting
and foraging habitat for a variety of bird species but surrounding development and mowed or limited understory
plants in the other tree groupings, except for K and I, reduce their overall habitat value. Tree Groups K and I
support greater woody species diversity and understory cover than Tree Groups B, F, G, H, J, L, M, N, and O
but lack continuity with Tree Groups A, C, D, and E.
The Riparian/Larimer County Canal No. 2 and the connected Upland Woodland habitat areas are the most
valuable and unique habitat features within or near the Salud project area. In terms of vegetation and wildlife
species diversity, wildlife habitat value, and potential to support sensitive plant and wildlife species, riparian,
wetland, and seasonal aquatic habitat along Larimer County Canal No. 2 represent the most important habitats
within or near the project area. These habitats are limited in areal extent along the Front Range and are usually
only found in association with perennial and intermittent drainages and other sources of surface water.
Wetlands and associated seasonal open water habitats provide foraging, resting, and breeding habitat for some
urban adapted species of waterfowl such as mallard and Canada goose. Wetlands with herbaceous and woody
vegetation cover also support a variety of other wildlife populations including small mammals, mammalian
predators, songbirds, reptiles, and amphibians. Larger trees and snags in riparian habitats provide important
foraging and/or nesting habitat for woodpeckers, variety of songbirds, and urban adapted raptors such as red-
tailed hawk and great horned owl.
The field survey located a large (~3-foot diameter) stick nest in the top of a large eastern cottonwood in Tree
Group A (see Figure 1 and Photos 5 and 8). The nest was in good condition but unoccupied since the timing of
the field survey was beyond the active nesting season of most raptors. However, based on the size and
configuration of the nest and the fact that a red-tailed hawk vocalized and was flushed from Tree Group A, the
nest was likely used by a pair of red-tailed hawks nest during the 2015 nesting season. The only other evidence
of possible raptor nesting activity observed during the field survey was hole opening to a possible nest cavity in
a large crack willow on the west side of Tree Group K. This cavity hole was of sufficient size to possibly support
nesting by eastern screech owl. It could also be used for nesting by woodpeckers or songbird cavity nesters.
Wildlife species, other than red-tailed hawk, observed in woodland habitats during the project area field survey
were mourning dove, broad-tailed hummingbird, northern flicker, blue jay, black-capped chickadee, and house
finch. In addition to these sighting, employees at a business adjacent to Larimer County Canal No. 2 indicated
they often see and hear a great horned owl using the riparian corridor.
(b) According to the Natural Resource Conservation Service (NRCS) soils mapping for the Salud project area
(http://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx), the predominant soils in the project area are Fort
Collins loam, Nunn clay loam, and Nunn clay loam, wet. Fort Collins loam and Nunn clay loam are not classified
as wetland (hydric) soils by the NRCS, but Nunn clay loam, wet is classified as a hydric soil. The Nunn clay
loam, wet soils-mapping unit is located in the north central portion of Grass/Alfalfa Hayfield habitat, but no
evidence of wetland vegetation or hydrology was found in this area.
The only location where evidence of all three wetland parameters (hydric soils, wetland hydrology, and wetland
vegetation), required by the U.S. Army Corps of Engineers (COE) for wetland determination, was found was
within the embankments of Larimer County Canal No. 2. Wetlands along Larimer County Canal No. 2 in the
project area are characterized by narrow (2 to 4 feet wide), linear stands of reed canarygrass (Phalaris

arundinacea) supported along the inner edge of the ditch banks. The wetland/upland boundary is defined by a
relatively sharp transition in vegetation dominance from reed canarygrass in the wetlands to upland plants such
as smooth brome at the top of the ditch banks. Wetlands along Larimer County Canal No. 2 were not delineated
since development would not impact Larimer County Canal No. 2. Based on an estimated wetland width of 2 to
4 feet on both sides of the canal, wetlands within Larimer County Canal No. 2 in the Salud project area are well
under 1/3 acre in size.
Section 3.4.1 of the City’s Land Use Code stipulates a non-development buffer of 50 feet for wetlands of this
size. Preliminary development plans for the Salud project call for a 50-foot setback from Larimer County Canal
No. 2 which would satisfy the City’s wetland buffer requirement except for the development of a planned
community garden adjacent to the north side of the canal. The plans also call for the removal of existing
buildings within the 50-foot buffer along the south side of Larimer County Canal No. 2. The buffer setback would
preclude direct impacts to wetlands within Larimer County Canal No. 2, assuming the proposed Salud Parkway
bridge crossing of Larimer County Canal No. 2 would span the entire canal. However, it is uncertain if a
community garden meets City standards for development activities within a buffer zone.
(c) Western and northern portions of the Salud project area provide relatively unobstructed views of the Front
Range foothills.
(d) As indicated under (a & i) the project area supports little native vegetation. Native herbaceous species are
restricted primarily to a few annual weeds. Eastern cottonwood, lanceleaf cottonwood, netleaf hackberry,
American plum, and chokecherry are the only native woody species found in the project area. All trees 6 inches
(dbh) or larger may be classified as significant by the City Forester. Siberian elm and Russian olive, however,
are classified as nuisance trees by the City of Fort Collins, but all trees provide some perching, foraging, and
nesting habitat value for songbirds.
(e) There are no natural drainages on or near the project area. Larimer County Canal No. 2 is a constructed
irrigation ditch that passes through the property.
(f) The property was evaluated with regards to potential habitat for state and federal listed threatened and
endangered species. Wetlands along Larimer County Canal No. 2 were judged to be the only areas that could
possibly provide suitable habitat for three federal listed threatened species, Preble’s meadow jumping mouse
(Zapus hudsonius preblei), Colorado butterfly plant (Gaura neomexicana coloradensis), and Ute ladies’-tresses
orchid (Spiranthes diluvialis). An evaluation of their potential presence is provided in the following paragraphs.
Suitable habitat for the jumping mouse is provided by low undergrowth consisting of grasses, forbs, or both in
open wet meadows and riparian corridors or where tall shrubs and low trees provide adequate cover. Potential
habitat includes wet meadow habitats, native hayfields, stream channels (perennial and intermittent), riparian
habitats, or floodplains below 7,600 feet elevation in Colorado. Saturated wetlands supporting dense stands of
cattail or bulrush do not provide suitable habitat conditions for the jumping mouse (U.S. Fish and Wildlife Service
1999; Armstrong et al. 1997)2. Suitable habitat conditions were judged to be absent for Preble’s meadow
jumping mouse because of the very narrow extent of wetlands dominated by reed canarygrass and the adjacent
presence of upland, non-native grassland and developed areas instead of moist native meadow.
The Colorado butterfly plant is a short-lived, perennial herb endemic to moist soils in mesic or wet meadows of
floodplain areas in southeastern Wyoming, north-central Colorado, and extreme western Nebraska. This early
to mid-seral stage species occurs primarily in habitats created and maintained by streams active within their

floodplains with vegetation that is relatively open and not overly dense or overgrown. It is found on subirrigated,
alluvial soils of drainage bottoms surrounded by mixed grass prairie at elevations of 5,000 to 6,400 feet
(Spackman et al., 1997, Federal Register, 1998)3. Populations of this species are often found in lowdepressions
or along bends in wide, active, meandering stream channels a short distance upslope of the actual channel.
The plant requires early to mid-seral riparian habitats. Typical habitat is relatively open without dense or
overgrown vegetation. It commonly occurs in communities dominated by redtop (Agrostis stolonifera) and
Kentucky bluegrass on wetter sites and by wild licorice (Glycyrrhiza lepidota), Flodman's thistle (Cirsium
flodmanii), curlycup gumweed (Grindelia squarrosa), and smooth scouring rush (Hippochaete laevigata) on drier
sites. These areas are usually intermediate in moisture between wet, streamside communities dominated by
sedges, rushes, and cattails, and dry shortgrass prairie (Federal Register 1998). Suitable streamside habitats
for Colorado butterfly plant are nonexistent within the project area.
Habitat for the Ute ladies'-tresses orchid typically consists of seasonally moist soils and wet meadows near
lakes, springs, or perennial streams and their associated floodplains below 6,500 feet. Associated vegetation
species typically include those with a "FACW" Corps of Engineers classification (Equisetum, Asclepias,
Calamagrostis, Solidago, etc. genera) occurring in relatively open and not overly dense, overgrown, or over-
grazed areas. This species prefers comparatively well-drained, high moisture content wetland soils that are not
strongly anaerobic or composed of heavy clays. Conversely, sites consisting entirely of dense stands of reed
canarygrass, those characterized by standing water including monocultures of cattails or three-square, dense
clayey soils, or highly saline soils supporting a dense community of inland saltgrass (Distichlis stricta) are not
considered to be habitat for this species (U. S. Fish and Wildlife Service memorandum: Plants - Spiranthes
diluvialis, Ute ladies'-tresses orchid, dated November 23, 1992). Wetlands supported along Larimer County
Canal No. 2 are comprised primarily of dense stands of reed canarygrass that do not create suitable habitat
conditions for Ute ladies’-tresses orchid.
(g) Past removal of native habitat has eliminated the potential for any special habitat features on the property
other than significant trees and riparian habitat along and adjacent to Larimer County Canal No. 2. The raptor
nest in Tree Group A also qualifies as a special habitat feature as well as Larimer County Canal No. 2 serving
as a potential wildlife movement corridor.
(h) Larimer County Canal No. 2 could provide a wildlife movement corridor for a variety of wildlife species that
would not be found in areas of urban development, and is the only wildlife movement corridor within 500 feet of
the project area. This canal originates at the Cache la Poudre (Poudre) River west of Cache la Poudre Junior
High School and passes through relatively undeveloped land until reaching the Salud project area. South of the
Salud project area, the canal passes through mostly developed sites until it drains into Warren Lake Reservoir or
Mail Creek. Its value as a movement corridor south of the project area is restricted by numerous road crossings
and underground segments. Larger mammals such as coyote, striped skunk, red fox, mule deer, and white-
tailed deer may occasionally move along the Larimer County Canal No. 2 corridor and hunt or forage in
undeveloped habitats in the Salud project area but its primary value as a movement corridor is for songbirds,
urban-adapted waterbirds, and small mammals.
Section 3.4.1 of the City’s Land Use Code stipulates a non-development buffer of 50 feet for irrigation ditches
that serve as wildlife movement corridor. Preliminary development plans for the Salud project call for a 50-foot
setback from Larimer County Canal No. 2 except for the development of a community garden. The setback
requirement is based on a distance measured from the top of the ditch banks. The plans also call for the
removal of existing buildings within the 50-foot buffer along the south side of Larimer County Canal No. 2. The
buffer setback would maintain Larimer County Canal No. 2 as a wildlife movement corridor. However, the

proposed Salud Parkway bridge crossing of Larimer County Canal No. 2 may have relatively minor effects on
the continuity of the corridor within the project area. This conclusion is based on the current presence of two
existing road crossings of the ditch within the project area. It is uncertain if a community garden meets City
standards for development activities within a buffer zone, but a community garden is unlikely to have an effect
on wildlife movement unless the garden is fenced.
(j) There is one issue regarding the timing of property development and ecological features or wildlife use of the
project area. If the development proposal includes removal of any trees on the property or if construction occurs
near an occupied bird nest during the raptor and songbird nesting season (February through July), these
activities could result in the loss or abandonment of a nest and would be in violation of the federal Migratory Bird
Treaty Act. Section 3.4.1 of the City’s Land Use Code stipulates the following regarding red-tailed and
Swainson’s hawk nest sites.
(a) No tree with an active nest shall be removed unless a permit for such removal has been obtained
by the developer from the United States Fish and Wildlife Service.
(b) To the extent reasonably feasible, trees that are known to have served as nest sites shall not be
removed within five (5) years of the last known nesting period. If the tree is removed, it shall be
mitigated in accordance with Section 3.2.1, Landscaping and Tree Protection Standards.
(c) A temporary limit of development (LOD) of a four-hundred-fifty-foot radius shall be established for
Red-tailed and Swainson's hawk active nest sites during the period from February 15 through
July 15 of the first year of a multi-year development construction project.
(k) Since the majority of the property proposed for development has been converted to development, Non-native
Grassland/Weedy, and Grass/Alfalfa Hayfield habitats, project development would have little impact on natural
habitats or important habitat features, other than existing trees on the property. Preliminary development plans
indicate that trees in Tree Groupings F, G, N, and O would need to be removed for building and road
development. Some trees in Group E along the north side of Larimer County Canal No. 2 would also likely be
removed for development of the community garden. Trees determined to be significant on the property should
be preserved to the extent possible. Removal of any trees classified as significant would need to be mitigated
with replacement trees, as determined by the City Forester based on the Land Use Code. Additional mitigation
plantings would also need to be made for loss of non-significant and nuisance trees providing wildlife habitat
value.
Since tree removal or construction near trees during the nesting season could result in the loss or abandonment
of a nest, it is recommended that tree removal or construction near raptor or songbird nests occur outside of the
nesting season (February 15 – July 31), or trees on or near the project area be surveyed to ensure lack of
nesting prior to removal or construction activities during the nesting season. This mitigation recommendation
would preclude the possible incidental take or disturbance of occupied nests. City required stipulations for
protection of the possible red-tail hawk nest and nest tree would also apply to protect nesting by this species.
Current development plans indicate a development setback of 50 feet would be maintained from Larimer County
Canal No. 2 except for a community garden. Currently much of the buffer area has been adversely impacted by
development and/or landscaping associated with development. It is recommended that additional plantings with
native shrubs and herbaceous species be completed within these previously disturbed areas and building
envelopes within the buffer to enhance habitat diversity within the buffer zone and provide additional vegetation
screening between Larimer County Canal No. 2 and proposed development. Any additional plantings would
need to be in compliance with the ditch companies’ maintenance requirements for Larimer County Canal No. 2.
One final mitigation recommendation is based on Article 3.2.4(D)(6) in the City of Fort Collins Land Use Code
that requires protection of natural areas and natural features from light spillage from off site sources. Therefore,
intensity of night lighting from the sides of structures facing the Larimer County Canal No. 2 buffer zone should

be shielded or directed to preclude the intrusion of artificial nighttime light into the landscaped buffer zone and
adjacent Larimer County Canal No. 2 corridor.
This concludes Cedar Creek Associates, Inc.’s evaluation of the Salud project area. If you have any questions
or require additional information regarding my evaluation, please give me a call.
