MEMORANDUM
DATE: April 30, 2021
TO: City of Bozeman Planning Department
FROM: Sarah Howell, Staff Scientist 2
RE: Lot 1 Annie Subdivision Phase 3C Wetland Delineation Summary
Bozeman, Montana
S02, T2S, R5E
WGM Group conducted a wetland and non-wetland waterway delineation at Lot 1 of Annie
Subdivision Phase 3C on April 7th, 2021. This delineation was conducted in accordance with the
1987 U.S. Army Corps of Engineers Wetland Delineation Manual of the U.S. and the Regional
Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains,
Valleys and Coast Region (Version 2.0). The delineation was performed to identify the presence
and extent of wetlands on the property and to map wetland boundaries so required setbacks
could be applied to the subdivision plans. The delineation limits encompass 3.24 acres and are
located within the southwest ¼ of the southeast ¼ of Section 2, Township 2 South, Range 5
East, P.M.M. in Gallatin County, Montana. The property is located on the north side of Durston
Road, just east of the intersection with North 25th Avenue in Bozeman (see Figure 1,
Attachment A). One wetland (WL-1) was delineated during the April 7th, 2021 wetland
delineation (see Figure 2, Attachment A).
The topography of the property is generally flat with the exception of a 1- to 1.5-foot-deep swale
running south to north on the eastern third of the property and the inset floodplain of the West
Fork of Catron Creek. The western two thirds of the property have been landscaped with trees,
shrubs and lawn while the eastern third appears more natural although disturbance is still
evident. The swale is lined with ponderosa pine (Pinus ponderosa) on the western edge and
yellow-twigged willow (Salix alba) on the eastern edge. A sample point (SP2U) was performed
in the middle of this swale to document the lack of wetlands. Herbaceous vegetation included
orchard grass (Dactylis glomerata), smooth brome (Bromus inermis), and common dandelion
(Taraxacum officinale).
The inset floodplain is about 12 to 15 feet wide on the west side of the West Fork of Catron
Creek and about 6 feet wide on the east side. Topography drops 2 to 3 feet down to the
floodplain and about another foot or so to the water surface in the stream. Vegetation within the
floodplain is dominated by FAC species including Kentucky blue grass (Poa pratensis), common
Timothy (Phleum pratense), and slender wild rye (Elymus trachycaulus). The soils were
checked hydric soil indicators at several locations within the floodplain, but criteria were not met
for hydric soils except for within a narrow wetland fringe along the stream. It is likely that the
stream no longer accesses this floodplain regularly due to hydrologic changes resulting from
development in the watershed.
The West Fork of Catron Creek and its wetland fringe were delineated as WL-1. The portion of
this wetland within the property is 0.07 acres. The channel is about 3 feet wide and 1 foot deep
and enters the property near the southeast corner through two concrete culverts. The wetland
fringe is 1-3 feet wide on each side. The stream runs along the eastern property boundary and
leaves the property near the northeast property corner. Wetland hydrology is supported by
surface water conveyed in the stream. Soils have a silt loam texture and are black at the surface
to about 14 inches depth becoming very dark grayish brown below. Soils met the criteria for the
loamy mucky mineral (F1) hydric soil indicator. Wetland hydrology indicators include primary
indicators of surface water (A1) and saturation (A3) and the secondary indicatory of geomorphic
position (D2). The National Wetland Inventory (NWI) classified this feature as palustrine,
emergent, persistent, temporarily flooded, excavated (PEM1Ax). No other wetlands were
mapped by NWI on the property.
One pair of sample points were documented to support the location of the wetland boundaries.
(see Attachment B – Wetland Determination Data Forms). Several additional soil pits were
used to determine wetland boundaries but were not recorded. WL-1 is likely jurisdictional due to
its connection to the East Gallatin River.
