Fort Collins, CO 80527
Date: August 9, 2023
To: City of Fort Collins, Planning, Development, and Transportation, Environmental Department
From: Cedar Creek Associates, Inc.
Subject: Sonders Village East - Ecological Characterization Study
This Ecological Characterization Study (ECS) Memo is submitted to address City of Fort Collins
Land Use Code (Section 3.4.1) requirements to identify habitats and natural resource areas on or
within close proximity of proposed developments. The Project Site is approximately 127 acres
(comprised of many parcels) and is situated just east of Turnberry Road and north of Richards Lake
Road (Figure 1). Onsite ecological characteristics were evaluated on July 2, 2023.
A data review was conducted to gather information and assist in the evaluation of potential natural
biological resources within the property. The data review entailed an evaluation of online resources
and publications to determine the presence or potential occurrence of important natural and
biological resources. This data review included:
• U.S. Fish and Wildlife Service (USFWS) Federally Listed and Proposed Endangered,
Threatened, and Candidate Species and Critical Habitat as identified by the USFWS
Information, Planning, and Conservation System (IPaC) Official Species List and Critical
Habitat Mapper;
• Migratory Bird Treaty Act (MBTA) and Bald and Golden Eagle Protection Act (BGEPA)
protected species as identified on the IPAC Trust Resources Report;
• The Colorado Natural Heritage Program database statewide species and natural community
tracking list for Larimer County;
• Colorado Parks and Wildlife (CPW) Threatened and Endangered Species List and High
Priority Habitat database (SB181);
• City’s Natural Areas Species of Concern list (Restoration Plan 2016-2025, 2016);
• The City’s Land Use Code (Article 3, Section 3.4.1);
• The City’s Natural Habitat and Features Inventory Map (2000);
• The Colorado Wetland Inventory (CWI);
• USFWS National Wetlands Inventory (NWI); and
• US Natural Resources Conservation Service (NRCS) Web Soil Survey.
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 & j – General Ecological Function and Wildlife Use) The project site is composed primarily
of former agricultural fields which have not been farmed in 2023. Therefore, the fields exhibit
degraded ecosystems which are comprised of annual invasive species and noxious weeds. These
degraded offer very limited wildlife value and ecological function. Other areas of the site, which
have not been farmed, are comprised almost entirely of smooth brome (Bromus inermis). There
are soil piles in these areas, which appear to have been placed there during construction of the
neighborhood to the southwest in 2005. There is a small grove of cottonwoods (Populus deltoides)
and Russian olive (Elaeagnus angustifolia) on the western edge of the property (along Turnberry
Road). The attached photos provide representative views of the Project Site. The #8 irrigation ditch
is immediately to the east of the Project Site. As described below, these feature provide wildlife
habitat for songbirds and urban adapted wildlife and the irrigation canal serves as a wildlife corridor.
Overall, wildlife use of the project site is low due to the degraded ecosystems comprised of annual
species and noxious weeds or monocultures of smooth brome. However, the #8 ditch provides
good wildlife habitat and elevated songbird activity was observed around that .
(b & f – Wetland and Water Delineation) Both the USFWS National Wetland Inventory and the
City of Fort Collins’ Natural Habitat and Features Inventory Map delineate the #8 ditch as an aquatic
feature. The field survey revealed that the ditch does qualify as an aquatic feature and in certain
areas exhibits wetland characteristics with areas inside of top of bank dominated by broadleaf cattail
(Typha latifolia).
(c – Prominent Views) The project area does not provide any significant or unobstructed views
of natural areas or other important visual features. However, the foothills can be seen from
certain parts of the project area. The project is primarily surrounded to the west by residential
development and infrastructure and a sod farm to the east.
(d – Native Vegetation Summary) As indicated under (a & i) the project area does not support
any significant native vegetation.
(e – Non-native Vegetation Summary) As described above, the areas containing perennial
grasses were dominated by smooth brome. The abandoned agricultural field were dominated by
the following species:
Common Name Scientific Name List
Kochia Kochia scoparia -
Russian thistle Salsola tragus -
Cheatgrass Bromus tectorum C
Prickly lettuce Lactuca serriola -
Lambsquarters Chenopodium album -
Musk thistle Carduus nutans B
Canada thistle Cirsium arvense B
Field bindweed Convolvulus arvensis C
(g – Sensitive Species Habitat) There are no sensitive species habitats located in the Project
Site. According to the attached CODEX report, no sensitive species have been observed within a
mile of the Project Area.
(h – Special Habitat Features) The CPW High Priority Habitat database did not exhibit any
features which overlapped the study area and no prairie dogs were observed onsite. The City Fort
Collins’ Natural Habitat and Features Inventory Map identified the following habitats in the study
area for the project (Figure 2), followed by the field description:
• Aquatic – This feature was verified to be the #8 irrigation ditch.
• Emergent Wetland – This feature along with other occurrences of emergent wetland were
found within the top of bank of the #8 irrigation ditch. The wetlands comprise a combined
0.25 acres.
• Native Upland Plains Forest – This feature was verified in the field, occurring across
Turnberry Road from the project site.
• Wet Meadow – This feature was mapped along the #8 irrigation ditch. However, it was not
verified in the field as the #8 ditch is contained within a deep channel with steep slopes
which transition to upland abruptly.
Figure 2 displays all natural features verified in the field.
(i – Wildlife Movement Corridors) The #8 irrigation ditch serves as a wildlife corridor for urban
adapted species mammals, songbirds, insects and other small wildlife.
(k – Timing Issues) If trees are proposed to be removed during the nesting season (from February
1st to July 31st), a qualified biologist should survey any trees on the project or within a half mile
for nesting activity. If active nests are found, the CPW recommended buffer zones and seasonal
restrictions (2020) should apply. These surveys ensure compliance with the Migratory Bird Treaty
Act and the Bald and Golden Eagle Protection Act by verifying no active bird nests are disturbed.
(l – Proposed Mitigation) According to the City of Fort Collins Land Use Code (Section 3.4.1),
No. 8 Irrigation Canal and the wetlands contained within top of bank of the canal should receive a
50-foot buffer. This is defined in the ‘Buffer Zone Table for Fort Collins Natural Habitats And
Features’ which states that irrigation ditches that serve as wildlife corridors shall have a 50 foot
buffer zone standard.

Colorado’s Conservation Data Explorer Project Review Report
Project ID: CODEX-2494 Review Date: 8/8/2023 05:32:59 PM
Project Report:
The information contained herein represents the results of a search of Colorado's Conservation Data
Explorer (CODEX) and can be used as notice to anticipate possible impacts or identify areas of interest.
This tool queries multiple conservation datasets and includes a synthesis of Colorado Natural Heritage
Program (CNHP) and Colorado Parks and Wildlife (CPW) data for sensitive animal and plant species and
natural communities. Care should be taken in interpreting these data.
Please note that the absence of data for a particular area, species, or habitat does not necessarily mean
that these natural heritage resources do not occur on or adjacent to the project site, rather that our files
do not currently contain information to document their presence. CODEX information should not replace
field studies necessary for more localized planning efforts, especially if impacts to wildlife habitat are
possible. Although every attempt is made to provide the most current and precise information possible,
please be aware that some of our sources provide a higher level of accuracy than others, and some
interpretation may be required. CODEX data is constantly updated and revised. Please contact CNHP,
CPW and our partners for assistance with interpretation of this report or to obtain more information.
Disclaimer:
1.This is a preliminary environmental screening tool. It is not a substitute for the potential
knowledge gained by having a biologist conduct a field survey of the project area. This review
does not constitute environmental consultation (including federal consultation under the
Endangered Species Act), land use permitting, or the review of site-specific projects by
CNHP and CPW and our partners.
2.This Project Report is based on the project study area that was entered. The report must be
updated if the project study area, location, or the type of project changes.
3.The Conservation Data Explorer (CODEX) data is constantly changing and being updated and is
not intended to be the final word on the potential distribution of special status species. Colorado is
large and diverse with plants, animals, and environmental conditions that are ever changing.
Consequently, many areas may contain species that biologists do not know about or species
previously noted in a particular area may no longer occur there. CODEX data contains
information about species occurrences that have actually been reported to CNHP, CPW and our
partners. Not all of Colorado has been surveyed for special status species, and surveys that have
been conducted have varied greatly in scope and intensity. Such surveys may reveal previously
undocumented population of species of special concern.

About CNHP Data
One of CNHP's core research activities is managing a statewide database that details the locations of rare and imperiled species and natural plant
communities in Colorado. We gather data from CNHP surveys and monitoring projects, as well as from partners and other trusted sources like

herbariums. All of our data are compiled and managed in the Biodiversity Information Management System (Biotics), a web-enabled database
platform hosted by NatureServe. The species and natural plant communities we track are assigned global and state imperilment ranks based on
rarity, threats, and trends, and their locations are mapped as element occurrences. Element occurrences include spatial data as well as details on
condition, size, and landscape context. This information allows us to track both overall distribution and site-specific details describing how well
elements are thriving at each location. We use element occurrences to delineate Potential Conservation Areas that represent the primary area
needed to support the element occurrences, and often include additional suitable habitat or buffers from disturbance. Please visit the CNHP website
for more definitions and details related to CNHP data in CODEX.
CODEX Report Definitions
CNHP Biodiversity Rank – The significance of a potential conservation
area in terms of its biological diversity ranging from B1 (Outstanding
Biodiversity significance meaning protection of this potential conservation
area can prevent a species from going extinct) to B5 (General interest or
open space for more globally secure species).
CNHP Edit Date– The date the CNHP potential conservation area record
was last updated.
CNHP Identifier– A unique identifier for each CNHP data type,
applicable only to CNHP data records.
CO Status – State status per Colorado Parks & Wildlife: Endangered
(SE), Threatened (ST), or State Special Concern (SC).
Common Name – The common name of the species or plant community.
Critical Habitat Status – Critical habitat status for federally listed
species under the Endangered Species Act.
Managed Areas Name – Name of the managed area.
Manager – The general land Manager.
Management Description - The general category of how the feature is
managed.
Other Species of Concern – Other globally rare species and plant
communities, BLM or USFS sensitive species, state listed species, or
Tier 1 and Tier 2 priority species from Colorado’s State Wildlife Action
Plan, and species of economic and recreational value.
Other Status – Other status such as BLM sensitive species (BLM), U.S
Forest Service sensitive species (USFS), and Tier 1 and Tier 2 priority
species from Colorado’s State Wildlife Action Plan (SWAP Tier 1, SWAP
Tier 2).
Owner – The general land owner.
Public Access – Level of public access to the feature.
