Canada thistle (Cirsium arvense) (FACU), field bindweed (Convolvulus arvensis) (UPL), flixweed
(Descurainia sophia) (UPL), dandelion (Taraxacum officinale) (FACU), cheatgrass (Bromus inermis) (UPL),
intermediate wheatgrass (Agropyron intermedium) (UPL), and orchardgrass (Dactylis glomerata) (FACU).
A few small stands of mature plains cottonwood (Populus deltoides - no classification given in National or
Colorado Plant List) are also located within the uplands. The dominant species in the understory beneath
these stands were smooth brome (UPL) and orchardgrass (FACU).
Neither upland sample site exhibited definitive hydrologic characteristics indicative of wetlands, although
FCN-4 was within a very shallow drainage connected to the delineated wetland area at the base of the
upland slope. Soils at the two upland sample sites did exhibit characteristics indicating reducing
conditions, however. At FCN-3 there were a few scattered mottles (10 YR 5/8) that contrasted with a low
chroma matrix color of 2.5 Y 5/2. Mottles at FCN-4 were more abundant and bright (2.5 YR 4/8) in contrast
to a low chroma matrix color of 2.5 Y 4/2. Although there were indicators of reducing conditions in the soils
at FCN-3 and FCN-4, the lack of wetland hydrologic and vegetation indicators provided sufficient evidence
to classify these sites as upland.
Indicators of reducing conditions in the soil was also noted at check holes within other portions of the
uplands. Evidence of reducing conditions in the soil and small pockets of species such as foxtail barley
(FACW) and flattened rush (OBL) were indicative of pockets of moister conditions within the uplands and
were assumed to be the result of irrigation practices and a wetter than normal spring and early summer.
Overall however, the upland portions of the survey area were dominated by upland associated vegetation
species and hydrologic indicators were absent.
Two areas of exception were noted along the western boundary of the property. An active irrigation ditch
paralleled and was adjacent.to this boundary along its entire length. Within the ditch, pockets of reed
canarygrass (Phalaris arundinacea) (FACW+) and occasional individuals of green bulrush (Scirpus
atrovirens) (OBL) were present indicating wetland conditions. In addition a small stockpond (with no
outlet) had been constructed near the northwest corner of the property. Mature plains cottonwoods
ringed the perimeter of the pond, and smooth brome (OBL), yellow sweetclover (Melilotus officinalis)
(FACU), and Kentucky bluegrass (FACU) were the predominant species in the understory. Neither of
these areas were sampled or classified as wetland since they had been constructed in an upland area for
agricultural purposes.
The preceding paragraphs summarize the results of the field work completed for the Fossil Creek Nursery.
A field map with an approximate delineation of the wetland boundary is attached for your review. I am
scheduled to meet with your contracted surveyor in the field on Thursday (July 20th) so that the boundary
can be accurately delineated. Please call if you have any questions, and I will be happy to discuss them
with you at your convenience.

Results
Soil Conservation Service (SCS) mapping for Larimer County indicated the following three soils map units
as occurring within the survey area.
Fort Collins loam - 5-9% slopes
Longmont clay - 0-3% slopes
Renohill clay loam - 3-9% slopes
Fort Collins loam is not a hydric soil. It is located in the northern half of the survey site and is a deep and
well -drained soil on terrace edges and the steeper parts of fans. Renohill clay loam is also not a hydric soil.
It is located in the southwestern portion of the survey area and is a moderately deep and well drained soil
on uplands. Longmont clay is located at the southeast corner of the survey area and as a narrow, east -
west oriented finger which bisects the site and separates the Fort Collins loam and Renohill clay loam
mapping units. Longmont clay is classified as hydric and consists of poorly drained soils that formed in the
alluvium mainly from clay shale. This soil is on flood plains and upland valleys.
One wetland area was delineated. The area coincides with the occurrence of the Longmont clay soil in the
southeast corner of the survey area and is located parallel and adjacent to South College Avenue. The
wetland consisted of areas dominated by OBL wetland vegetation and two small areas of standing water.
The ponded areas did not support any vegetation and were assumed to have been created by excavation
of borrow material used in the construction of South College Avenue.
The wetland was mapped on the basis of vegetation, soil, and hydrologic characteristics (FCN-1 and FCN-
2). The delineated wetland boundary corresponded to a shift in vegetation dominance from obligate
wetland species to species found primarily on upland sites. Hydrologic wetland characteristics were
present as either standing water or saturated soils throughout all but the most northern (up gradient)
portion of the wetland. Although standing water or saturated soils were not evident, the northern portion
of the wetland was within the general drainage pattern leading into the wetland and was assumed to be
saturated earlier in the year based on vegetation and hydric soil characteristics.
The vegetation community at sample point FCN-1, within the northern -most portion of the wetland, was
dominated by creeping spike-rush (Eleocharis rnacrostachya) (OBL), flattened rush (Juncus compressus)
(OBL), and Emory's sedge (Carex emoryi) (OBL). Total vegetation cover was nearly 100 percent with most
(90 percent) contributed by OBL species. Mottles, indicating reducing conditions and hydric soils, were
abundant and bright (7.5 YR 6/8) in contrast to a low chroma matrix color (2.5 Y 4/2) within 4 inches of the
surface. Other check holes in the area displayed essentially the same soil coloration characteristics.
The vegetation community at sample point FCN-2, in the southern portion of the wetland, was adjacent to
one of the small ponds. Dominant vegetation at this sample site consisted of creeping spike-rush (OBL),
Emory's sedge (OBL), narrow -leaf cattail (Typha angustitolia) (OBL), and (oxtail barley (Hordeum jubatum)
(FACW). Total vegetation cover was over 90 percent with most (85 percent) contributed by FACW to OBL
species. Mottles, indicating reducing conditions and hydric soils, were abundant and bright (7.5 YR 5/8) in
contrast to a low chroma matrix color (5 Y 4/2) from the surface down to free water. Below the free water
level gleyed soils (gray -colored), indicative of anaerobic or waterlogged conditions, were also evident.
Hydrologic indicators included saturated soils from the surface and free water below 16 inches in depth in
the soils test pit.
Uplands mapped within the survey area displayed distinct non -wetland characteristics for at least two of
the three characterization criteria (vegetation and hydrology). The uplands are represented by sample
points FCN-3 and FCN-4. Vegetation at the two sample sites and other upland portions of the survey area
were dominated by UPL forbs and introduced and native pasture grasses. At FCN-3 smooth brome
(Bromus inermis) (UPL) and slender wheatgrass (Agropyron trachycaulum) (FACU) were the dominant
species contributing 80 percent of the total vegetation cover, while at FCN-4 Kentucky bluegrass (Poa
pratensis) (FACU) was dominant. FACU species comprised nearly 70 percent of the total vegetation cover
at FCN-4. Other common vegetation species noted in the upland portion of the survey area were

RE: Fossil Creek Nursery PUD Wetland Survey
Dear Jim:
RECEIVED
BY:
I spent some additional time keying out some of the more difficult to identify plants noted on the Fossil
Creek Nursery PUD parcel. As a result the species determination for two of the more dominant wetland
associated species has changed. The species changes had no effect on the wetland determination or
delineation in the field. I have modified the report and data sheets, however, to ensure technical
accuracy. The corrected report and data sheets are enclosed. Please replace the entire first report with
this submittal.
Once you have had a chance to reviewed the surveyed wetland boundaries in relation to potential
development plans, please give me a call to let me know if any additional consultation or wetland mitigation
planning will be necessary.

RE: Fossil Creek Nursery PUD Wetland Survey
Dear Jim:
At your request, Cedar Creek completed a wetland survey of the Fossil Creek Nursery PUD parcel on July
14, 1995. This survey was conducted to fulfill the requirements of Section 404 of the Clean Water Act,
regarding the delineation of wetlands prior to potential development activities. This parcel of land
surveyed consisted of 15 acres approximately 0.25 to 0.5 miles south of Trilby Road on the west side of
South College Avenue.
Study Methodology
Wetland mapping and delineation work was completed using the methods and techniques specified for
"routine on -site delineations" in the publication Corps of Engineers Wetlands Delineation Manual (1987).
Project maps were reviewed in the office to familiarize field personnel with the project site. Soil
Conservation Service (SCS) mapping was also reviewed prior to field work to determine the potential
location of hydric soils and to become familiar with site -specific soil properties. A cursory examination of
the property was made prior to field mapping to verify property boundaries and access routes through the
project acreage and to identify site -specific vegetation community characteristics. Field investigations and
wetland delineation were then initiated.
Sample points along and within suspected boundaries were selected to properly identify and delineate
wetland/upland boundaries. A formal field data sheet was completed for each sampling point. At each
sample point, percent total cover of dominant plant species was estimated. Species were then classed as
OBL (obligate wetland species), FACW (facultative wetland species), FAC (facultative species), FACU
(facultative upland species) or UPL (obligate upland species). A predominance of FAC, FACW, or OBL
plant species is the vegetation parameter indicating wetland presence. Soil and hydrologic data were also
collected to determine the presence or absence of wetlands at each sampling point. Wetland soil
indicators potentially include the presence of a histic epipedon, mottling, gleying, and high organic matter
content and/or organic matter streaking in the surface layers of sandy soils. Potential wetland hydrologic
indicators include topographic position, presence of standing water and/or saturated soil profile
conditions, drainage patterns, and oxidized root channels in the upper 12 to 18 inches of the soil profile.
As indicated in the 1987 Corps of Engineers manual, vegetation, soils, and hydrologic wetland indicators
must be present in order to classify an area as wetland.
In conjunction with formal sampling sites, numerous "check holes" were dug to further aid in making
wetland/upland boundary determinations. Check holes provided additional vegetation, soil, and
hydrologic information useful for refining boundaries between wetland/upland transition zones. Such
information was also used to better characterize wetland and upland conditions within the survey area.
Field data sheets were not completed for check holes.
Following the analysis of site characteristics, the wetland/upland boundary and sample points (FCN-1
through FCN-4) were flagged with pink fluorescent tape and yellow fluorescent pin flags tied with pink
tape, respectively, for subsequent survey work. The results of the field analysis are summarized in the
following paragraphs. Copies of the data sheets completed in the field are included as attachments to this
letter.
