Introduction
This report documents wetland boundary delineation on a portion of the Gianinetti property next
to the town of Carbondale, in Garfield County, Colorado. Claffey Ecological Consulting (CEC)
delineated the boundaries in the project Area in May and June of 2017. The project area is a
smaller portion of the property and the applicant proposes an event center to hold various public
and private events in the project area known as the Event Center Parcel. The property is
currently managed for agricultural production, a recreational fishing, and includes an existing
pavilion structure used for private events.
Applicant and Site Information
Gianinetti Family Partnership
Mr. Ernie Gianinetti
592 Cowen Drive
Carbondale, CO 81623
Section 27, Township 7 South, Range 88 West
Lat: 039° 23' 51.98", Long -107° 09"34.23"
Roaring Fork River and Lyons Ditch
Background and Landscape Setting
The project area is near the confluence of the Roaring Fork (RF) River and the Crystal River in
the lower montane — Pinyon Juniper woodland ecosystem. Most of the property is in the
bottomlands of the RF and portions are within the 100 year FEMA floodplain. The RF river
frames the north side of the property. The Crystal River meets the RF about 1 mile down valley
(west) of the site. The west side of the project area is a steep alluvial terrace slope that leads to
the large terrace on which the Town of Carbondale sits. The property is a mix of irrigated
pastures and hay meadows, mature cottonwood gallery forest along the river mixed with blue
spruce, herbaceous and scrub -shrub wetlands, and early successional stage cottonwood,
serviceberry and Russian olive along fencerows. Various farm buildings, equipment stored,
corrals and a small pond are also located on the property.
The project area is shown of the attached map by Boundaries Unlimited , and this Event center
project area is bound on the north and west by the two spring creeks, or ditches (Lyons Ditch).
Those creeks start from groundwater east of the property in the larger floodplain and irrigated
pastures to the east of the property. They may be supported by irrigation diversions as well.
The applicant originally retained CEC to delineate wetlands on a larger project area on the ranch
in spring of 2017.
I visited the site in April collected some data and had previously arranged for the applicant to
hold off on any flood irrigation in the hay meadows and pastures in that larger project areas.
After consideration of future plans, the family had revised the proposed development and
reduced the size of the project area, more than once in 2017. The applicant was concerned with
the loss of hay production on the meadow. Irrigation of the project area was not conducted until I
had finished flagging, and the project area shown was decided prior to flagging the wetland
2
boundary in May 2017. That project area for the Event Center has been significantly reduced in
size and shifted from west to east but still includes all of the area I examined for the delineation.
The main part of the project area is an irrigated hay meadow that is framed on the north and west
by sides by two spring creeks and their adjacent wetlands. In late April the wetlands adjacent to
the spring creeks were obvious, but the hay meadow vegetation was not recognizable by species.
Hay harvesting the previous year had eliminated many plant parts for species ID and only
obvious leaf parts for Poa and a few other species like orchard grass were identifiable. The hay
meadow was elevated well above what appeared to be obvious wetlands and natural groundwater
levels, and it appeared that without irrigation, the meadow would be non wetland. We started
early to allow for possible irrigation by mid June and possibly some hay harvest.
The soils contained gravels and river cobbles in the upper layers indicating relatively rapid
drainage. Once we had some vegetative growth it was fairly obvious at the early June site visit
that the majority of the meadow was not hydrophytic vegetation, and although the adjacent
spring creeks were running at or above bankfull. The Roaring Fork River was approaching
bankfull but still below that elevation.
Methods
The wetlands were delineated in accordance with the US Army Corps of Engineers 1987
Wetland Delineation Manual (Environmental Laboratory 2007), and the 2010 Supplement to the
Manual for Western Mountains and Valleys (Corps 2010). The most recent wetland indicator
plant list was used for Western Mountains and Valleys (Lichvar et al. 2016). We used Version
8.1 of the USDA Field Indicators of Hydric Soils in the United States (USDA-NRCS 2017).
Brad Johnson of Johnson Environmental assisted with wetland determinations on June 2, and
helped flag boundaries. Prior to that flagging effort, Travis Morse of the Corps of Engineers
visited the site in the morning of June2, 2017, and confirmed evidence at the deep soil pits and
the lack of hydrology. We walked the site at looked a swale on the southern end of the project
area, dug a shovel pit in the swale and observed the obvious wetlands framing the main meadow.
On May 15, 2017 a mini -hoe was available on site, and we dug a series of deep test pits in the
meadow to evaluate soils and hydrology. The vegetation was starting to develop enough to
realize some species, but not completely. Sample pits 1-8 were dug with the mini hoe to depths
of about 32 inches with instructions to stop where rock refusal became difficult for the hoe.
Based on the plant cover identified later and the relatively level topography of the entire meadow
without much variation in elevations (thus less variation in groundwater depths), the number of
deep test pits was probably excessive. In a few, rock refusal created shallower pits then 32
inches (it was not a large mini hoe). We examined soils in these pits at varying depths and also
observed hydrology on May 15, and again on June 2. Mr. Ernie Gianinetti provided rainfall data
for the Carbondale area between those two dates.
The wetland flags were surveyed by Boundaries Unlimited who prepared the attached plans and
wetland boundary map. The Gianinetti project area for this report is significantly smaller than
what we had agreed as a delineation project area. We project sample points and wetland lines
outside of the project area for display purposes but the only area needed for verification at this
3
point is the Event Center area shown on the attached plans. That area is only 4.8 acres in size
and includes 0.27 acre of wetlands adjacent to the northern spring creek.
The Web Soil Survey showed the meadow as Redrob Loam which is not a hydric soil. The NWI
Mapper on Google Earth shows the two spring creeks as linear channels but no wetland polygon
adjacent on the creeks or in the meadow. The nearest PEM is approximately 430 feet east of the
pavilion and is a wetland adjacent to the along the RF river.
Results
The main meadow is an irrigated hay meadow and does not really contain a real hydrophytic
plant community. The attached sample points completed for the original delineation project area
may include a few points that had hydrophytic plant community but that is primarily because Poa
pratense and Juncus balticus were included, and these species do really well in irrigation and are
not great plant indicators of wetlands. The meadow rises in elevation from west to east, and is
generally higher by approximately 2 to 3 feet than the wetlands adjacent to the spring creeks.
Groundwater from the spring creek's alluvial aquifer or the RF River does not reach within 2 feet
of the surface during spring runoff. We monitored the pits until June 2, and although the river
was not at the peak of runoff we would expect to see some soil saturation and water in the pits at
less than 2 feet. The spring creeks/ditches were running at bankfull flow and wetlands adjacent to
the creeks were saturated near the surface.
The meadow in the event center area is the driest part of the meadow. The dominant grass is
orchard grass (Dactylis glomerata) a FACU species but bluegrass (FAC) and a few other
hydrophytes might be present but generally it is an upland community and much of it under the
pavilion.
The wetland which is 2 feet lower or more than the meadow consists of a mix of willow (Salix
exigua), sedges (Carex utriculata and Carex aquatilis) in the wetter areas near the creek, cattail
(Typha latifolia), redtop (Agrostis gigantea) and a good deal of reed canary grass (Phalaris
arundinacea). The soils were saturated near the surface and inundation was present in the few
areas as the spring creek was at bankfull. The soils were silty clay loams for the most part and
we did not do a sample point in this part of the wetland as it was so obviously wetland. The
delineation in this area was easy and straight forward due to elevation breaks and changes in the
plant community from manicured lawn to a hydrophytic plant community.

Conclusion
The majority of the project area for the Event Center is an upland. The 0.27 acre of aquatic
resources mapped in the Event Center Project Area would be a mix of palustrine emergent
(PEM) and palustrine scrub shrub under Cowardin et al (1979), and the open water of the creek.
They would be riverine wetlands under the HGM classification system (Hauer et al 2002).
There are not any impacts anticipated at this time to wetlands or other aquatic resources.
The Event Center Project area is in for County review at this time. The applicant has requested
additional delineation work for the area of the Cabins which is east of the project area (see
Figure 2). We looked at this area in 2017 and believe this primarily uplands, but there is a ditch
and adjacent wetlands that need to be assessed, and any wetlands flagged.
The attached plan C.1 from Boundaries Unlimited, labeled Gianinetti Spring creek Guest Ranch,
event Center Parcel Existing Conditions, Figure 1, is an accurate depiction of the aquatic
resources we flagged on June 2 in the Event Center project area. We request verification of the
aquatic resources (wetlands and creek channel) depicted on this plan.
