Engineering Comments
General Comments
1. If not already filed for the subject site, the applicant will need to provide and file
with the County Clerk and Recorder's office executed Waivers of Right to Protest
Creation of Special Improvement Districts (SID’s) for the following:
a. Street improvements to W Garfield Street including paving, curb/gutter,
sidewalk, and storm drainage
The document will be provided to the applicant after Site Plan submittal for the
applicant’s convenience. The applicant must provide a copy of the filed SID waiver
prior to Site Plan approval.
TD&H: Thank you, the applicant will complete and file the SID waiver once the document is
received from the City.
Sewer
2. Show the connection of the sewer service to the sewer main on the Utility Plan with
the Site Plan application.
TD&H: The existing sewer service connection to the sewer main is shown on civil sheet
C3.1. We propose to extend this existing service to the new building rather than connecting
to the sewer main with a new service.
3. Provide the existing and proposed invert elevations on the Utility Plan with the Site
Plan application.
TD&H: The existing and proposed sewer service invert elevations have been added to the
Utility Plan, civil sheet C3.3.
4. Engineering recommends the sewer cleanout(s) be located in a visible area that won’t
get covered in snow in the winter months for maintenance access.
TD&H: The sewer cleanout has been moved to the sidewalk outside of the west door.
Easements
5. Show the existing sewer easement for the sewer main on the Utility Plan with the
Site Plan application.
TD&H: The existing sewer easement has been labeled on the Utility Plan civil sheet C3.3.
Storm Drainage
6. Bozeman Municipal Code (BMC) 38.220.020.A.2.g.(9) Site Plan submittal
requirements - The grading plan on the west side does not match the approved
grading plan for the Bozeman Gateway Site Z project. Coordinate with the adjacent
property owner and tie into the grading to the west.
TD&H: We have coordinated with the Bozeman Gateway Site Z project and have updated
the grading to reflect this.
7. BMC 38.220.020.A.2.g.(9) Site Plan submittal requirements - The location of the
curb inlet on the northwest corner of the grading plan does not match the Bozeman
Gateway Site Z project. Coordinate with the adjacent property owner to the west to
show the correct location.
TD&H: After coordination with the Bozeman Gateway Site Z project, the location of the
existing curb inlet at the northwest corner of the project site is not changing. The Site Z
project has chosen to extend the curb further to the west and removing the existing parking
island. Our plans have been updated to reflect this change in the layout from the existing
conditions.
Water
8. BMC 38.410.130.A.1 Water Rights - The applicant must contact Brian Heaston
with the City Engineering Department to obtain a determination of cash-in-lieu (CIL)
of water rights if not already paid. Payment will be required prior to Building Permit
approval.
TD&H: Thank you, the applicant understands this requirement.
Sewer
9. The Dental Amalgam Rule requires dental offices to install amalgam separators,
follow best management practices and submit a one-time compliance report to their
POTW or other control authority. The applicant must coordinate with Mark DeWald
(MDeWald@Bozeman.net), City pretreatment program coordinator prior to Site Plan
approval.

Transportation
10. BMC 38.400.010. A.5 Streets, General –If this lot is installed prior to the Bozeman
Gateway Site Z lot to the west, a temporary 20 foot gravel drive will need to be
installed to extend the western drive aisle to the existing drive access because it’s
considered a dead-end. No dead-ends longer than 150 feet are permitted without an
approved turn-around.
TD&H: It is understood that the Bozeman Gateway Site Z project will be installed first, but
we have added a temporary fire access road on civil sheet C3.5.
Street Lights
1. BMC 38.270.030. Completion of Improvements. All street lights need to be installed
along Garfield prior to occupancy. Show street lights on the Site Plan.
TD&H: All street lights from the master subdivision plans which are on or adjacent to the project
property have been added to the site plan.
2. BMC 38.570.030. Street Lighting. Install street lights per City of Bozeman Design
Standards and Specifications Policy (DSSP) Standard Specs for lighting section XII.G
Table 1. The light should be 300 feet from the proposed Bozeman Gateway Site Z light to
be installed on the west side of the intersection of S 29 th and Garfield.
TD&H: Placing a light 300-ft to the east of the proposed Garfield Street light from the Bozeman
Gateway Site Z project would put the light off the project property to the east. We located a new
Garfield Street light 200-ft to the east of the proposed Site Z street light.
Site
11. Clearly show the northern pavement and walkway boundary end on the Site Plan.
TD&H: The northern pavement and walkway boundary can be seen on civil sheet C3.1.
