RE: 705 S Church Ave
Traffic Impact Study Waiver Request
Bozeman, Gallatin County, Montana
Dear Karl:
The purpose of this letter is to request a waiver from performing a traffic impact study for a two lot minor
subdivision proposed at 705 S Church Ave. Hyalite Engineers performed a trip generation estimate for this
project that will include a two lot minor subdivision with a townhouse.
The trip generation analysis was performed using generation rates found in the Trip Generation Manual;
11th Edition published by the Institute of Transportation Engineers (ITE) for estimating average vehicle trip
ends based on Land Use Code 210 – single-family detached housing. There are only two scenarios that
need to be analyzed for this specific land use, the weekday morning peak hour and the weekday evening
peak hour. The weekday morning peak hour is projected to generate a total of 1 trip and the weekday
evening peak hour is projected to generate a total of 1 trip with an average daily trip of 10. The results of
this analysis are presented in a table included with this waiver request.
The townhouse being proposed at 705 S Church Ave is below the threshold for requiring a traffic impact
study per City of Bozeman standards. The added trips to the transportation system are not anticipated to
have any significant impacts to the surrounding area and the intersections to access the property can
operate as they do today.
Let me know if you have any questions regarding this waiver request, or if anything else needs to be
provided or clarified. Please give me a call or send an email to bmegaard@hyaliteeng.com with any
questions.
Sincerely,
Brett Megaard, P.E.
Project Manager
