Re: Bozeman Gateway Ph 4 Subdivision Preliminary Plat Resubmittal
COB#: 19436
MMI#: 3638.009
Dear Sarah:
This letter is to provide written responses to the comments stated in the engineering review memo dated
January 17, 2020. Below are our responses associated with each comment.
ENGINEERING COMMENTS:
Easements
1. BMC 38.410.060.E – Easements. Sidewalks outside of the ROW for Technology Boulevard
West will require Public Access Easements, prior to Preliminary Plat approval. The response
from the applicant to this unaddressed review comment was that the sidewalks outside of the
ROW are covered under the reciprocal access easement described in the Declaration. The
Declaration only allows for “lot owners, their tenants, their respective tenants, employees,
customers, and invitees.” This language does not cover the public who are not patronizing the
businesses.
Ted’s attorney provided the following response. “The sidewalks addressed in the above
comment will border, and be immediately adjacent to, Technology Boulevard West.
Pedestrians will be able to access the sidewalks freely from the ROW. The Declaration
ensures public access by prohibiting the construction of any barrier that would
obstruct pedestrian access:
“[N]o fence or other barrier which would unreasonably prevent or obstruct the passage
of pedestrian or vehicular travel for the purposes permitted by this Declaration shall be
erected or permitted within or across the easement areas,” except for specific
allowances such as mailboxes, landscaping, curbing, and other traffic controls. This
language is found on Page 12, Section 4.01(b) of the Declaration.”
Also, there is existing conditions in Phase 2 and 3. Any location where there is on
street angle parking and sidewalk is adjacent to the curb no easements were required
other than what is specified in the Declaration.
2. BMC 38.410.060.B.1.b – Easements. The proposed 10 foot utility easements on either side of
Technology Boulevard West must not be under a sidewalk. Move them back behind the sidewalk
or relocate the utility easements with approval from all impacted utilities, prior to Preliminary
Plat approval. If northwestern energy has approved the location, provide written documentation
showing this.
Correspondence with northwestern energy has been included in this resubmittal.
Street Lighting
3. BMC 38.570.030 – Street Lighting. Street lights must be installed along the north side of
Garfield Street from Harmon Stream Boulevard to the eastern boundary of this Phase spaced per
City of Bozeman standards prior to Final Plat approval. A Special Improvement Lighting District
(SILD) must be created prior to Final Plat approval. Note that Bozeman Gateway Site Z project
will likely be creating a SILD so adding these lights to that SILD will be acceptable. Due to the
lighting being required to be spaced at a certain distance (see the DSSP), and not wanting a
patchwork of lights down a collector street, the City will not allow lighting to go in based on
development of each Site Plan along the north side of W Garfield Street.
An overall street light layout along Garfield Street has been included in this resubmittal.
Groundwater
4. BMC 38.220.060 – Preliminary Plat Supplements. Based on the hydrograph from IR 2, the
groundwater elevation is as shallow as 1 foot below existing ground surface. Therefore, no crawl
spaces or basements will be permitted on this entire phase. The applicant must add the following
note to the Conditions sheet of the plat: “This subdivision is in a known area of high groundwater.
No crawl spaces or basements may be constructed in the development. Sump pumps may not be
discharge onto streets or into curb and gutter.”
The note has been added to the conditions sheet of the plat.
Transportation
5. Staff reviewed all previous approved Design Development manuals and did not find any specific
references to double angle parking in each direction of travel. The City Engineering Department
is not approving the double angle parking on Technology Boulevard West. Technology
Boulevard, referred to as Main Street in the manual, runs through Phases II, II, and IV of this
Subdivision and must continue the section built in Phase II and III. This may address above
review comments related to a utility easement not being permitted to run under sidewalks as well
as sidewalks being outside of the ROW.
Documentation has been submitted to show this configuration was previously approved in a
2014 PUD modification.
6. BMC 38.400.080 Sidewalks. Sidewalks must be installed along the north side of Garfield from
the intersection of Harmon Stream Boulevard to the eastern boundary of this Phase prior to Final
Plat approval.
Understood.
If you should have any questions regarding these comments, revisions and corrections for the Bozeman
Gateway Phase 4 Preliminary Plat don’t hesitate to contact me,
