Re: Trip Generation
MEMO DETAILS:
The subject property is located at 605 E Bryant Street in Bozeman, Montana and is defined as Lot 7 of
Industrial Properties Subdivision. Trip generation estimates for the proposed development are based
on Trip Generation 9th Edition – Institute of Transportation Engineers (ITE).
The proposed site improvements will involve construction of two adjoining shop units with garages,
each with 1 ADU living space above. The proposed use for the commercial shop space is to provide a
workshop and storage space for tradesmen or small business owners who need a staging ground, but
have little to no customer/retail interaction, while the upper floor will provide residential living space
for the owners of the commercial shops. An existing 2-bedroom single-family residence is located on
the property and will remain in its current condition/configuration under the proposed improvements.
The two proposed ADU units are each 1-bedroom.
The land use closest to the proposed project is for residential condominiums/townhouses (Section 230
of ITE manual) and warehousing (Section 150 of ITE manual). Trip generation values were calculated
separately for the two land uses, which were then summed to determine the total trip generation for
the site. Table 1 provides a summary of trips generated based on the number of dwelling units. Table 2
provides a summary of the trips generated based on the gross floor area of the proposed workshop
space. Table 3 shows the combined, total trip generation for the site.
According to the ITE manual, the weekday A.M. and P.M. peak hour of the generator typically
coincides with the peak hour of adjacent street traffic for both residential condominiums/townhouses
and warehousing. Therefore, only one A.M./P.M. peak hour, which represents both the peak hour of
the generator and the peak hour of the adjacent street traffic, is displayed.
