associated with these streams. This species occurs in seasonally
moist soils and wet meadows, and prefers partially shaded open
glades or pastures and meadows in full sunlight. Based on
information gleaned from this wetland delineation, it has been ,
ascertained, that suitable habitat is not found at the Horstooth
East site, and species that are commonly associated with the
orchid are not present. No further survey -for S. diluvialis is
required.

Soil mapped onsite by the Soil Conservation Service (Soil Survey
of Larimer County, 1980) is predominantly Map Unit 35, Fort
Collins loam, 1-3% slope. This deep, well -drained soil is formed
in alluvium, and is found on terraces and fans. This is not a
hydric soil.
This parcel contains one wetland area, in the southeast corner. A
depressional area is partially surrounded by young trees and large
shrubs; species include Russian olive (Blaeagnus angustifolia),
plains cottonwood (Populus sargentii), and willow (Salix spp.).
The wetland is found within this area, where willows are the "
dominant vegetation and the soil surface is damp. Sample site 3
is at the edge of the wetland, with mostly willows and a few
alders (Alnus tenuifolia), and a small percentage of encroaching
upland vegetation comprised of thistles (Cirsium spp.) and white
sweetclover (Melilotus alba). The soil is saturated at a depth of
12 inches; soil color is 7.5YR 4/2 with bright mottles and a high
sand content.
The wetland boundary generally follows the willows; the central
portion of the depressional area is almost entirely comprised of
white sweetclover and thistle and is not considered to be wetland.
Sample site 4, within the wetland boundary, is slightly different
in vegetative composition; dominant species are willow and bulrush
(Scirpus americanus); additional species present in small numbers
are white sweetclover, smooth brome (Bromus inermis), thistle and
cottonwood. Soil is saturated at 10 inches; color is lOYR 3/2
with moderate mottling and a higher clay content.
The outer edge of the bank of the irrigation ditch was also
examined for the presence of wetlands, since sedges (Carex spp.)
were abundant in some areas. Small patches of reed canarygrass
(Phalaris arundinacea) are found within the ditch. However, at
sample sites 1 and 2, no evidence of wetland hydrology is found,
and soils are very dry. Mottling is absent or slight, and soil
matrix color is 10YR 4/3 and 4/4. Upland weedy species, primarily
thistles, are present along the ditch in varying densities,
interspersed with patches of sedges and some beardless wheatgrass
(Agropyron inerme) and wheat (Triticum aestivum). Thus, the ditch
system outside the.bank-to-bank area is considered to be
nonwetland because it does not meet wetland criteria for
vegetation, soils and hydrology.
The remainder of this site, a mowed field, is also upland because
of vegetation, soil and hydrologic characteristics. Dominant
vegetation is smooth brome and thistle; these are upland species.
Vegetative cover ranges from approximately 85-100%.

Dear Mr. Ward;
As per your request, Cedar Creek completed a wetland survey and
delineation on a parcel within the Horsetooth East Business Park,
in the northeast quarter of Section 31, Township 7 North, Range 68
West. This parcel consists of approximately 0.75 acre of open
land adjacent to Timberline Road just south of Horsetooth Road,
Fort Collins. The property is bounded by Big Horn Drive on the
north, Timberline Road on the east, Automation Way on the west,
and a small irrigation ditch on the south. Surrounding land uges
are commercial and residential development.
The wetland survey and delineation follows the guidelines for a
"routine on -site determination" as developed by the U.S. Army
Corps of Engineers in the Wetlands Delineation Manual of 1987.
This survey was conducted to fulfill the requirements of Section
404 of the Clean Water Act regarding delineation of wetlands prior
to potential development activities.
Wetland delineation was completed using the techniques and methods
specified for 'routine on -site delineations' in the publication
Corps of Engineers Wetlands Delineation Manual (1987). Following
the analysis of site characteristics, the wetland/upland boundary
and sample points (.S1-S4) were flagged with fluorescent orange
tape and pin flags. The results of the field work are summarized
in the following paragraphs. Copies of the data sheets completed
in the field are included with this letter. A map which displays
the approximate delineation line is also included; please note
that it is not to scale, but is intended to show an approximation
of wetland boundaries and sample site locations.
