Re: Cherry Creek Mixed Use
Lot 12 of Gallatin Park Subdivision
Traffic Study Waiver Request
TBD Gallatin Park Dr.
Dear Engineer,
The Site Plan for the Cherry Creek Mixed Use Project on Lot 12 of the Gallatin Park Subdivision is being
completed and will be submitted to the City of Bozeman Community Development Department soon. The
purpose of this letter is to request a waiver from performing a traffic study. Lot 12 is part of the Gallatin Park
Subdivision, and traffic was already considered in the 1999 design report completed by TD&H, submitted
with the subdivision. Access to and from Lot 12 will be from existing Gallatin Park Dr.
The Site Plan for Lot 12 includes 21,312 SF of Commercial (manufacturing) building space and 24 residential
units, split between 7 buildings on the site. Traffic calculations, using the ITE Trip Generation calculator, are
below:
Manufacturing = 3.82 ADT per 1,000 sf
Residential Condo = 5.81 ADT per Dwelling Unit
Manufacturing = 21,312 sf
Residential Units = 24 units
Manufacturing = 21,312 sf/1000 x 3.82 ADT = 81 ADT (16 peak hour trips)
Residential = 24 units x 5.81 ADT = 140 ADT (12 peak hour trips)
Total Proposed ADT = 221 ADT (28 peak hour trips)
Gallatin Park Subdivision Traffic Calcs
According to Appendix D of the 1999 Gallatin Park Subdivision Design Report by TD&H, Gallatin Park Drive
(formerly Silverado Drive) was expected to see 4,660 ADT. According to the subdivision plat, the road
provides access to 21.2 acres of lots within the subdivision. Lot 12 is 2.01 acres, or 9.5% of the total lot area
of the subdivision. Allocating the 4,660 trips by lot area would equate to 441 ADT for Lot 12 from the design
report.
The proposed 221 ADT is less than the planned 441 ADT per the design report. With this information, we
request a waiver from the requirements of a traffic study.
