City of Bozeman Development Review Conformance:
Wetland and Watercourse Regulations Worksheet
Project: Northwest Crossing Subdivision
Conformance Review by: Lynn Bacon, PWS, TerraQuatic, LLC
Date Received: 12/19/19
Date Review Completed: 12/30/19
______________________________________________________________________________________
The following worksheet was compiled by TerraQuatic (TQ), LLC from the City of Bozeman, Chapter 38 Unified Development Code*. The
worksheet is compiled of city wetland and watercourse regulations and designed to expedite analysis of development review conformance. Most
regulation descriptions were condensed for the purposes of brevity and analysis. All references to wetlands and watercourses in other Articles or
regulations may not be included in this document because of redundancy. Responses of “yes” or “no” in the “Answer” column do not necessarily
imply noncompliance. To indicate compliance, a ‘yes’ or ‘no’ answer is in black font; unknown or noncompliance findings are in red font. Blue
font indicates a response that must be made by the city review authority and may have no bearing on aquatic resource regulation conformance.
Quick-summary reference tables have an orange heading to assist the city with expedient conformance analysis; gray headings are detailed
regulation tables.

Answer Comments
Any stream, river, creek, drainage,
waterway, gully, ravine or wash in which
some or all of the water is naturally
occurring, such as runoff or springs, and
which flows either continuously or
intermittently and has a definite channel, bed
and banks, and includes any area adjacent
thereto subject to inundation by reason of
overflow. In the event of a braided or other
multiple channel configuration of a
watercourse, the area of the watercourse

ARTICLE 30. – WETLAND REGULATIONS
Section 38.30.010. – Title and Applicability
Answer Comment
The City of Bozeman’s regulations pertain to
direct hydrologic connection to “waters of the
U.S.” (those wetlands that connect to a
federally-regulated stream or river directly or
via a series or watercourse, wetlands or
ditches), and also to isolated wetlands with no
direct connection to a water of the U.S. and
exhibit positive wetland indicators for all
three wetland parameters. The provisions
contained in these regulations do not apply to
wetlands created by a wholly manmade water
source used for irrigation purposes or
stormwater control.
Yes
Unknown
All features within the property boundary are jurisdictional.
It is unknown if aquatic features occur within 50 feet beyond the
property boundary; this issue requires attention.
Are there wetlands within the proposed
project area that are known jurisdictional
wetlands? If so, list identification/Cowardin
type.
Yes Riverine; dominant wetland fringe is emergent; this information
is important to planting plan issues.
Are there wetlands within the proposed
project area that are known nonjurisdictional
wetlands? If so, list identification /Cowardin
type.
No Unknown if wetlands within 50 feet outside of the property
boundary exist, and if so, if they would qualify as
nonjurisdictional.
A. Were wetlands discovered during the
development review process?
Yes

Other important regulations to consider during project conformance analysis:
ARTICLE 41. – SUBMITTAL MATERIALS AND REQUIREMENTS
Section 38.30.090. – Wetland Permits Conditions
A. The review authority may recommend conditions of approval for proposed regulated activities, and the city may conditionally
approve proposed regulated activities, subject to the following conditions:
1. Requiring the provision of a wetland buffer of a size appropriate for the particular proposed activity and the particular
regulated wetland area;
2. Requiring that structures be appropriately supported and elevated and otherwise protected against natural hazards;
3. Modifying waste disposal and water supply facilities;
4. Requiring deed restrictions or covenants regarding the future use and subdivision of lands, including but not limited to the
preservation of undeveloped areas as open space and restrictions on vegetation removal;
5. Restricting the use of an area, which may be greater than the regulated wetland area;
6. Requiring erosion control and stormwater management measures;
7. Clustering structures or development;
8. Restricting fill, deposit of soil and other activities which may be detrimental to a wetland;
9. Modifying the project design to ensure continued water supply to the regulated wetland; and
10. Requiring or restricting maintenance of a regulated wetland area for the purpose of maintaining wetland functions.
11. A yearly mitigation monitoring report to be submitted to the review authority on a yearly basis, with the due date to be
determined on a case-by-case basis.
12. A deed restriction to be filed with the county clerk stating the measures that will be taken to protect all water resources,
mitigation, and buffer areas in perpetuity.
13. That all reasonable effort has been made to limit indirect impacts to vegetation, faunal interspersion and connectivity, and
hydrological connectivity in the site design (e.g., any structures, boardwalks, viewing platforms, or bridges, which are
constructed within wetlands will have at least a two-foot space between the bottom chord of the structure and the wetland surface
elevation to limit shading impacts and allow wetland vegetation to persist).
14. The review authority may recommend conditions to mitigate for locally-regulated (wetlands not connected to a water of the
U.S.) infringement upon watercourses, buffers, or negative indirect or direct effects on the functionality of wetlands,
watercourses or buffers.
