Reference: Traffic Impact Study Waiver Request – Bozeman Health Phase 1
Project No. 17095.13
Dear Taylor:
The purpose of this letter is to provide information to support a traffic impact study
(TIS) waiver request for Phase 1 of the Bozeman Health Campus Master Plan. A TIS was
previously completed in support of the original master site plan, which was
submitted in November of 2023. Phase 1 now does not include any new building
square footage
The current Phase 1 plan proposes expansion of Lot E further west to add
approximately 162 parking spaces, expansion of Lot A to the northwest to add
approximately 197 parking spaces, and removal of Lot I, which will displace
approximately 150 parking spaces. The old maintenance yard will also be brought to
compliance with this phase. The net number of new parking spaces added with Phase
1 will be 209. The current phasing plan is shown in the attached figure.
The construction of additional parking is typically accompanied by an increase in
demand. However, in this case the Phase 1 parking expansion serves to meet an
existing demand for surplus spaces as determined through surveys of current
patrons, and will allow for visitors to park closer to the building frontages. The
proposed parking increase will also prepare the campus for future phases of the
master plan, which will ultimately include a new building and two existing building
expansions.
Due to the above, trip generation estimates were not calculated for the proposed
parking lot expansions. Future phases that include new building square footage will
include trip generation calculations to evaluate consistency with the assumptions
presented in the original TIS and review of recommendations from that study.
The proposed Phase 1 parking expansion is likely to shift existing vehicles using Lot I
to Lot E. The external ingress and egress routes from Highland Boulevard are not
anticipated to change based on the Lot E expansion and therefore would not
influence intersection operations. Access to the Lot A expansion will be via Entrance 1

from Highland Boulevard, and exiting vehicles will have the option to utilize a
northbound one-way approach onto Ellis Street east of Lot G. This approach will be
maintained as a northbound one-way road due to the large trucks that access a
loading bay on the east side of Medical Office Building (MOB) 4. It is anticipated a
higher demand of ingress trips to Lot A will utilize Entrance 1 and a higher demand of
egress trips from Lot A will utilize Ellis Street.
The intersections of Highland Boulevard with Old Highland Boulevard and Entrance 1
each have northbound left-turn lanes and Entrance 1 has a southbound right-turn
lane. The Highland Boulevard/Ellis Street intersection is signalized with left-turn
lanes on all four approaches. Each of these intersections is equipped to handle
additional demand from a potential redistribution of parking demand on the site.
If you have any questions or concerns, please feel free to contact me at 406-922-4326
