1.0 Introduction
The proposed Stillwater Acres Development is located in Weld County bordered by Weld
County Road 15 on the west, and the Greeley and Loveland Canal on the north. The site
is currently being used for agriculture. Wildland Consultants, Inc. completed a field
reconnaissance of the site on March 29, 2004 to evaluate site potential for threatened and
endangered species. The field reconnaissance was completed by Eric Berg of WCI. Mr.
Berg is a Certified Wildlife Biologist and a Certified Professional Wetland Scientist.
2.0 Vegetation and Wetlands
The vegetation on the site is dominated by agricultural land. The Greeley and Loveland
Canal and Farmers Irrigation Ditch support vegetation typical of maintained irrigation
ditches in the area. These ditches are maintained on an annual basis and support seeded
grasses and weeds.
A drainage swale runs across the center of the site. A wetland occurs along the bottom of
this drainage swale. The drainage swale connects to the Big Thompson River south of
the development area. Dominant plant species in the wetlands include: American
threesquare, hard stem bulrush, cattail, reed canarygrass, and meadow fescue.
Photographs of the drainage swale are included in Attachment A. A few large
cottonwood trees are located along the drainage swale.
3.0 Threatened, Endangered, and Special Status Species
There are no known locations of rare plants on or near the development site (System for
Conservation Planning 2004).

The wetlands associated with the drainage swale on the site provides potential habitat to
the federally listed Ute ladies' tresses orchid (Spiranihes cii ivualis). This rare orchid
occurs along streams and associated wetlands that flow into the South Platte River(U.S.
Fish and Wildlife Service 1992). The area around the drainage swale provide marginal
potential habitat to the federally listed New Mexico butterfly plant (Gaura neomexicana).
This annual plant occurs in sub-irrigated, alluvial soils of drainage bottoms in Weld
County (Spackman et. al 1997). No surveys for either species have been completed on
the development site.
The drainage swale on the site provides poor potential habitat to the federally listed
Preble's meadow jumping mouse. The nearest good Preble's habitat is located along the
Big Thompson River south of the development site. The Preble's mouse prefers riparian
habitat with extensive brush cover(USFWS 1999). The drainage swale and wetlands on
the site do not provide the thick brushy riparian habitat preferred by the Preble's mouse.
The irrigation canals on the site are maintained (burning, herbicides) on an annual basis.
Both canals provide poor quality potential habitat to federally listed species.
4.0 Conclusions, Recommendations
The proposed development has been designed to protect wetlands and natural vegetation
areas. The attached aerial photo shows the relationship of proposed development lots and
outlots that will remain as open space. The majority of the drainage swale(including
wetlands) is located within Outlots A and B (a total of approximately 19 acres). These
outlots will remain as open space. MI potential habitat for the Ute ladies' tresses orchid
and Colorado butterfly plant are located in these outlots. A portion of Lot 8 includes the
south end of the drainage swale. However, the building envelope for Lot 8 is located
outside of the drainage swale area. Because of project design no direct impacts to
wetlands and potential rare plant habitat will occur with construction. Surveys of the site
for the Ute ladies' tresses orchid and Colorado butterfly plant should not be required
because impacts to potential habitat will be avoided.
Because of the lack of shrubby riparian habitat the site provides poor potential habitat to
the Preble's meadow jumping mouse. No direct impacts will occur to the wetlands on the
site. Building envelopes are buffered from the drainage swale from 200-400 feet. Based
on these conditions surveys for the Preble's meadow jumping mouse are not
recommended for the site.
Based on current project design development will result in no impacts to jurisdictional or
non jurisdictional wetlands. No permits from the Army Corps of Engineers should be
required for project construction.
