The understory at the site consists of upland and wetland vegetation. Upland vegetation includes
pasture land consisting mostly of Smooth brome (Bromus inermus) and upland wheat grasses
(Agropyron spp.). Dominant wetland vegetation is listed in Table 2 above.
4.2 Soils
The project site wetlands were comprised of one primary soil series as mapped by the Soil
Conservation Service (USDA 1980). According to the Soil Survey of Lorimer County, Colorado
(USDA 1980), the soils within the wetlands at the project site are characterized as follows.
Altvan — Satanta loams 3 to 9 percent slopes
This series consists of deep, well drained soils that formed in mixed alluvial deposits. This
complex consists of gently sloping to strongly sloping soils on high terraces, benches and fans that
are underlain by sand and. Pemiability is moderate.
4.3 HvdroloQy
The wetlands within the survey area are associated with two ground water seeps. The recharge source
for the seeps may be the regional water table however the exact source could not be determined.
4.4 Wetland Determination
The wetland delineation at the project site identified two areas (wetland A and B) that comprised a total
of 0.38 acre of jurisdictional wetlands. The delineated wetlands areas are shown on the site map in
Appendix A. The National Wetlands Inventory (NWI) map for the Fort Collins quadrangle (USFWS
1975) did not list these areas as wetlands. However, according to the NWI Cowardin classification
system (Cowardin 1979), the jurisdictional wetlands identified at the site would be classified as
palustrine wetlands type. Palustrine wetlands include areas commonly called marshes, wet meadows,
swamps, bogs, or riparian zones where water depths in the deepest part of the basin are less than 6.6
feet during low water periods.
Table 3 summarizes the results of the multi -parameter approach to wetlands determinations for each
sampling location.

3.0 ]METHODS OF ANALYSIS
3.1 Routine Procedures
The routine procedure selected for identifying and delineating wetlands is a multi -parameter approach
requiring positive evidence of hydrophvtic vegetation, hydric soils, and wetlands hydrology. If these
parameters are met, the area is determined to be jurisdictional wetlands. The wetland delineation
routine procedures are adapted from the Corps of Engineers Wetlands Delineation Manual (COE
1987), which provides a logical, defensible, and technical basis for wetlands delineation. This routine
procedure stresses on -site inspection together with preliminary data gathering and synthesis of
available information.
At sampling points, the vegetation present was categorized using the National List of Plant Species
that Occur in Wetlands: Central Plains (Region S) (Reed 1988) and Rocky Mountain Flora (Weber
1976). Hydric soils and wetlands hydrology determinations were also made at each sampling site to
determine the extent of the wetlands at the project site.
The wetland delineations for the project site Were conducted by Mr. Geiselman on December 12, 1999
and January 7, 2000 and are documented on the site map, located in Appendix A and on field notes,
located in Appendix B.
3-1

1.0 INTRODUCMON
J. D. Padilla is currently working to develop a parcel of land called Harmony Ridge PUD — Phase II
(hereafter referred to as the project site) in Larimer County, Colorado, for real estate development.
The U.S. Army Corps of Engineers (COE) requires a report from an individual who is qualified to
delineate jurisdictional wetlands regarding the presence or absence of wetlands on lands proposed for
development. Jurisdictional wetlands are wetlands areas that fall into the domain of regulatory
oversight. This report is written to satisfy this requirement for proposed land development. The
wetlands delineation described in this report identified 0.38 acre of jurisdictional wetlands within and
adjacent to the project site. The wetlands occur in two locations on the south facing hill slope (wetland
A and B).
1.1 Purpose
The purpose of this report is to document a study to identify and delineate jurisdictional wetlands
within the project site in Larimer County, Colorado and to satisfy Section 404 of the Clean Water Act.
Section 404 authorizes the U.S. Army Corps of Engineers (COE) to issue permits for the discharge of
dredged or fill material into waters of the U.S.; including wetlands.
1.2 Site Location
A map showing the general location of the project site is provided in Appendix A. It is located in the
Northwest corner of Section 3, Township 6 North, Range 69 West of the 6th P.M., in the County of
Larimer, State of Colorado. Coordinates for the site were estimated from an U.S. Geological Survey
(USGS) 7.5-minute Fort Collins quadrangle map and are 105° 6' 80" west longitude and 400 3 P 37"
north latitude.
1.3 Site Description
The majority of the Harmony Ridge survey area consists of an upland prairie. Upland vegetation
includes smooth brome (Bromus inermis) and upland wheat grasses (Agropyron spp.). The general
slope and drainage pattern of the site is to the south towards the Trilby Lateral with the elevation
ranging from approximately 5,150 to 5,100 feet amsl.
Two drainages within the survey area contain wetland vegetation. The wetland vegetation consists
primarily of Broadleaf cattail (Typha latifolia), Creeping spikerush (Eleocharis macrostachya), Reed
Canary grass (Phalaris arundinacca), Olney's three -square (Sccirpus americanus), and Torrey's rush
(Juncus torreyi). The Trilby Lateral borders the project site on the south side. Ground water seepage
appears to be the main source of water supporting the wetlands.

RE: Jurisdictional Wetlands Delineation, Harmony Ridge PUD — Phase II
Corps File No. 200080042
Dear Mr. Geiselman:
Reference is made to the above -mentioned project located in the NW 1/4 of Section 3, Township
6 North, Range 69 West, Larimer County, Colorado.
This project has been reviewed in accordance with Section 404 of the Clean Water Act under
which the U.S. Army Corps of Engineers regulates the discharge of dredged and fill material, and any
excavation activities associated with a dredged and fill project, into waters of the United States which
may include streams, open water lakes, ponds or wetlands.
This letter is to inform you that this office considers the wetland delineation map dated January
14, 2000 accurate and acceptable. The wetlands are considered to be waters of the United States
pursuant to Section 404 of the Clean Water Act. If a proposed activity requires work within these waters,
this office should be notified by a proponent of the project for proper Department of the Army permits.
This wetlands jurisdictional delineation is valid for a period of five years from the date of this
letter unless new information warrants revision of the delineation before the expiration date.
If you have any questions concerning this matter, please feel free to contact me at (303) 979-
4120 and reference Corps File No. 200080042.

Dear Ms. Kreimeyer:
As per your request, this letter is written to address impacts to, and mitigation options for
jurisdictional wetlands located within the Harmony Ridge — Phase II development which is owned
by J.D. Padilla. The project site is located in the northwest corner of Section 3, Township 6 North,
Range 69 West of the 6th P.M., in Fort Collins, Colorado.
Wetland delineations at the site were conducted on December 8, 1999 and January 7, 2000 and are
described in the attached report entitled Jurisdictional Wetlands Delineation for Harmony Ridge —
Phase II, January 2000. Two separate wetlands areas were delineated at the site. Both are located on
the south facing hill -slope and appear to be the result of ground water seepage. A copy of the
jurisdictional wetland acceptance letter from Mr. Terry McKee of the U. S. Corps of Engineers is
also attached for you review.
Development plans at the site indicate that both wetland sites will be impacted. As required by the
U. S. Corps of Engineers and the City of Fort Collins, the impacted wetlands will have to be
mitigated. Because there will be very little acreage left on -site to mitigate the wetland losses, the
owner is proposing to mitigate the wetland losses in Fort Collins at an off -site location. Jim Sell
Design is currently investigating potential mitigation locations and will notify your office as soon as
a site is confirmed. Mitigation will be in the form of wetland creation on a I to 1.5 basis or wetland
enhancement on a 1 to I basis. Upon selection of a mitigation site and type, a Clean Water Act
Section 404 permit application will be submitted to the U. S. Corps of Engineers, Tri-Lakes office
for approval. All Corps correspondence will be available for your review.
If you have any questions concerning this letter or attachments please call me at (970) 224-5289.
