Subject: Minnewashta Apartments Development Traffic Engineering Support
Chanhassen, MN
INTRODUCTION
TC2 has been engaged to provide traffic engineering support for the proposed Minnewashta
Apartments development located at 6440 Hazeltine Road (Hwy 41) in the City of Chanhassen.
The proposed development is a 44-unit multifamily development with one (1) access planned
to Hazeltine Road (Hwy 41) across from Minnetonka Middle School West. The main objective
of this support is to identify the expected trip generation of the proposed development and
collaborate with City staff / area agencies to understand potential traffic impacts and timelines
associated with the proposed development and Hwy 5 detours planned in the next couple
years. The following information provides some preliminary information related to the project.
PRELIMINARY TRAFFIC REVIEW
A trip generation estimate for the proposed development was created using the ITE Trip
Generation Manual, 11th Edition, which includes trips for typical weekday a.m. and p.m. peak
hours, as well as daily. The proposed development, based on the average rate using ITE Code
220 (Multifamily Housing – Low Rise), is estimated to generate 18 a.m. peak hour (4 in / 14 out),
22 p.m. peak hour (14 in / 8 out), and 298 daily (149 in / 149 out) trips. Based on this trip
generation, the site would generate about one (1) vehicle trip every three (3) minutes during
the peak hours. At this level of trip generation, the change in overall intersection operations of
the proposed access is anticipated be minimal.
NEXT STEPS
TC2 will continue to collaborate with City staff and area agencies to review detour-related
information provided to help understand potential traffic impacts and timelines associated with
the proposed development and Hwy 5 detours. A subsequent memo will be developed in
consultation with City staff and area agencies. If you have any questions, please feel free to
contact me at your convenience.
