RECOMMENDATIONS
The following recommendations are presented for optimum noxious weed suppression and
control within the project area. Recommendations include treatments prior to construction,
during construction, and after construction and landscaping are completed.
1. Ensure that only certified weed free seed is utilized for any seeding during and
after construction and landscaping (Colorado Seed Act, § 35-27-101 through 125,
C.R.S. [1993 Supp. As amended by Senate Bill 93-17] Rules and Regulations
Pertaining to the Administration and Enforcement of the Colorado Seed Act).
2. Ensure that only weed free hay, straw or mulch is utilized for any mulching
during and after construction and landscaping (Weed Free Forage Crop
Certification Act, § 35-27.5-103, C.R.S. [1993 Supplement] Rules and
Regulations Pertaining to the Weed Free Forage Crop Certification Act).
3. Keep on site all topsoil which is collected from the site and which is to be
reapplied after construction during the landscaping phase to prevent dispersal of
weed seeds and cuttings to other sites.
4. Remove noxious weeds such as cheatgrass, where appropriate and cost efficient.
using mechanical means such as hand pulling.
5. Treat weed sprouts on all stockpiled topsoil piles with appropriate herbicides at
least 7 days prior to reapplication of topsoil to the site for landscaping.
6. Treat all landscaped areas with a grass tolerant broad leaf specific herbicide or
mixture of broad -leaf herbicides in the early fall after construction and
landscaping are completed. This treatment should be applied in the fall only if
landscaping was completed early enough to allow treatable weed sprout growth to
occur prior to treatment. Otherwise, postpone treatment to the following mid to
late spring after sprouting has occurred.
7. Monitor all landscaped areas frequently to identify noxious weed infestations
early while minor chemical and mechanical treatments can be implemented
effectively.

PROBLEMS
A factor which may have affected the thoroughness and accuracy of the noxious weed survey
was the timing of the survey, i.e. time of year the survey was conducted. The contractor's
schedule necessitated conducting the survey in late -spring before some plant species had
sprouted and grown to a size which facilitated specific identification. This may have resulted
in the omission in identification of some weed species which would be readily identified later
in the year, but which would be missed in the spring. Additional noxious weed species were
identified during site visits later in the summer, however, and these are included in this
report. Control measures recommended in the management plan should be formulated so as
to be as broad as possible to adequately treat species which would have a high probability of
being indigenous to the site.
Another factor to be considered in formulating a Noxious Weed Management Plan specific to
the Centre Avenue, The Grove, site, is the extent and nature of the proposed construction
work. The entire project corridor is proposed for extensive disturbance through clearing,
grubbing and extensive grading. Most topsoil is proposed for removal, stockpiling and then
reapplication to the site during landscaping after construction is complete. This presents
special problems in that most methods of weed control are precluded as ineffective, too time
consuming or too costly with the exception of the application of herbicides.

NOXIOUS WEED SURVEY
Natural Resource Services, Inc. conducted a noxious weed survey over the entire The Grove
at Fort Collins project site on May 28, 2012. The entire project site was thoroughly walked
by Steve C. Johnson, Senior Ecologist for NRSI during a five hour period. Noxious weed
species were identified, locations were noted on an aerial photograph, and densities of
individual species were noted at each identified location. In addition, vegetative community
types within the site were mapped using Global Positioning System (GPS) technology. The
following state and county listed noxious weed species were identified and mapped during
the initial field survey and during additional site visits throughout the summer of 2012.
Canada thistle (Cirsium arvense)
Common mullein (Verbascum thapsus)
Downy brome/Cheatgrass (Bromus tectorum)

Existing Vegetation and Land Use
All of the project area was farmed or ranched in the past. Vegetative communities which
occupied the site prior to the initiation of the present construction were composed almost
entirely of introduced species common in formerly ranched or farmed sites. Dominant
species included smooth brome (Bromus inermis), Canada thistle (Cirsium arvense), field
bindweed (Convolvulus arvensis), Russian olive, and others.
Wildlife
A number of wildlife species potentially utilize the area of the project site. Wildlife species
which are probable inhabitants or migrants utilizing the site include numerous species of
songbirds and other bird species including redtail hawks (Buteo jamaicensis), Swainson's
hawks, (B. swainsoni), owls, and other hawk species, mourning doves (Zenaidura
macroura), etc. Potential mammalian species which might utilize the site include cottontail
rabbits (Sylvilagus auduboni), raccoons (Procyon lotor), red fox (Vulpes fulva), coyote
(Canis latrans), striped skunk. (Mephitis mephitis), longtail weasel (Mustela frenata), mink
(Mustela vison), a number of bat species, whitetail deer (Odocoileus virginianus) , mule deer
(Odocoileus hemionus), and a number of rodent species. Coyote, whitetail deer, red foxes,
cottontail rabbits, and numerous bird species were observed on the site during the 2012 site
assessments.
Wetlands and Riparian Areas
A riparian zone adjacent to a ditched tributary to a stream known as Spring Creek was
located along the north boundary of the project area (Figures 2 and 3). A number of wetland
plant species, herbaceous and woody, were associated with this riparian zone. Several
species of trees [peachleaf willow (Salix amygdaloides), crack willow (Salix fragilis), plains
cottonwood (Populus deltoides), and Russian olive] and shrubs [coyote willow (Salix exigua)
and golden currant (Ribes aureum)] occupy the areas within and adjacent to the creek.
Cattails (Typha latifolia) and other herbaceous wetland species characterized the corridor.
NOXIOUS WEED MANAGEMENT REQUIREMENTS
Natural Resource Services, Inc. was requested by Campus Crest Communities through
Ripley Design, Inc. of Fort Collins on January 31, 2012 to complete a Noxious Weed Survey,
a Noxious Weed Management Plan (IMP) and control implementation for noxious weeds
located on the The Grove in Fort Collins project site. The IMP and weed control were
required by the City of Fort Collins as part of the permitting process for the project.
The requirement for the noxious weed survey and IMP stem from requirements incorporated
into the Colorado Noxious Weed Act, § 35-5.5-101 through 119, C.R.S. (1991 as amended).
This law charges state and local governments in Colorado with the management of noxious
weeds. As part of the required management, each local government must adopt an
"undesirable plant management plan" directed at controlling noxious weeds and a
"designated noxious weed species list" which their plan would target. Noxious weeds, as
specified in § 35-5.5-103, C.R.S. (2000 and as amended) means an alien plant or parts of an
alien plant that have been designated by rule as being noxious or has been declared a noxious
weed by a local advisory board, and meets one or more of the following criteria:

PROPOSED DEVELOPMENT
The proposed development project consists of the construction of a mixed -use residential
development consisting of a number of residential apartments, parking areas, and a central
features area which will include a central green and an amenity area. Three access streets are
planned for construction through the 34+/- acre property. Also, the existing Larimer Canal
No. 2 is to be rerouted to the south which will provide a semi -forested natural wildlife
movement corridor bordering the project site to the south.
PROPERTY LOCATION
The Campus Crest The Grove project site is located immediately west of Centre Avenue,
south of Gilgalad Way, and immediately north of the Larimer Canal No. 2 in the city of Fort
Collins, Larimer County, Colorado (Figures 1 and 2). The tract is located at approximately
400 33' 34"North latitude x 1050 5' 22" West longitude (UTM Zone 13 492470m E x
4489917m N). .
SITE DESCRIPTION
The area surrounding the project is characterized by developed residential areas to the west
and north, open rolling prairie with scattered large plains cottonwoods (Populus deltoides)
and Russian olives (Elaeagnus angustifolia) along the Larimer Canal No. 2 to the south, and
developed government office complexes to the east. A riparian area designated by Fort
Collins as a Natural Habitats Zone occupies the northern portion of the project site along a
drainage ditch which is a tributary of Spring Creek (Figures 2 and 3). The project area
contains a total of approximately 34 acres.
Weather
The weather in the proposed project area is typical of the central Colorado high plains.

Topography within the site is characterized as gently rolling to hilly prairie which varies by
no more than 100 feet in elevation throughout the site (Figure 2). No unusual natural
features or rock outcrops are present on the site.
Existing Infrastructure
The project area was historically utilized as farmland and pastureland for cattle and horse
grazing and hay production. No structures were present on the site immediately prior to the
initiation of construction of the proposed The Grove project. The project area was possibly
irrigated for hay production in the past. Development of high density residential
subdivisions, commercial and government office space, retail space, and recreational areas
has been occurring in the area for several decades.

The Grove Mixed Residential Development Project
Larimer County
Fort Collins, Colorado
INTRODUCTION
The mixed residential development known as The Grove at Fort Collins is currently under
construction within Fort Collins, Colorado. The project is being developed by Campus Crest
Development, Inc., 2100 Rexford Road, Suite 414, Charlotte, North Carolina. Under
construction requirements imposed by the City of Fort Collins (personal communication with
Lindsay Ex on May 11, 2012), the developer is required to 1) complete a noxious weed
assessment of the site, 2) complete a written Integrated Management Plan (IMP) which
describes proposed control methods to be used in controlling state and locally listed noxious
weeds identified within the site, 3) implement active control of identified noxious weeds, and
4) implement a three year monitoring program, to include annual written reports, which will
assess the success of the aforementioned control measures.
This plan was completed to fulfill Item 2 of the above mentioned requirements.
On April 16, 20 , Campus Crest Development, Inc. contracted with Natural Resource
Services, Inc. (NRSI), a Georgia company authorized to conduct business in Colorado, to
complete a noxious weed survey, an Integrated Management Plan (IMP), and noxious weed
control for noxious weeds located on the The Grove project site. Under the contract, NRSI
was to 1) conduct a noxious weed survey of the site according to procedures and guidelines
outlined in the Colorado Noxious Weed Act, Title 35, Article 5.5, 2) compile a list of
noxious weed species which may inhabit or are determined to be present on the site, 3)
prepare draft management recommendations in the form of an Integrated Management Plan
(IMP) for noxious weeds identified within the site, 4) implement noxious weed control of
identified noxious weeds within the site, and 5) complete monitoring of the site for three
years to assess the success of noxious weed control. All recommendations and the IMP
would be prepared in accordance with guidelines provided by the Colorado State Weed
Coordinator and the local governmental agencies involved with jurisdiction over the project.
These agencies include the City of Fort Collins, Colorado; Larimer County, Colorado and the
Colorado Department of Agriculture.
In completing this IMP, NRSI received valuable assistance and comments from Ms. Lindsay
Ex, Environmental Planner, City of Fort Collins; Ms. Melissa Hill, Senior Development
Manager, Campus Crest Communities; and Mr. Josh Schreppel, Senior Project Manager,
Campus Crest Construction.
