Re: Development / Access Review Comments: Preliminary Plat and Site Plan for 2100
Stoughton Avenue (River Valley Industrial Center) located at PID #250030700 and
#301370090 adjacent to County State Aid Highway 61 (Chaska Blvd.) and the intersection
of CSAH 61/CSAH 15/Audubon Rd.
Thank you for the opportunity to review the subject development in the City of Chanhassen. The County
assumes compliance with State Statute 505.03 Subdivision 2 regarding road authority review. Consistent
with the County Comprehensive Plan and County Codes, the following are comments and recommended
conditions of approval and potential requirements for any necessary permits to be issued for the project:
1. Regarding access
a. No direct access to CSAH 61 is proposed. Additional County review and approval will be
required if this condition changes.
b. The proposed access from the site to Audubon Rd. (City street) is approximately 350 ft.
from the intersection of CSAH 61/CSAH 15/Audubon Rd. and shows planned impacts to
the left turn lane serving the southern leg of the intersection. New local road access on local
roads near County intersections is guided to be approximately 660 ft. from the intersection
or at the greatest distance possible considering site constraints in order to avoid impacts to
turn lanes serving the County Highway intersection and to minimize conflicts with traffic
turning on to and off of the County Highway. In addition, the adopted CSAH 61/TH 41
Corridor Study final report identifies the future roadway concept for this intersection,
which includes a median on the south leg of the intersection for at least 400 ft. south of the
intersection (Link to adopted study, See page 39).
i. Revise the proposed site plan regarding the access on Audubon Rd. to remove the
access or shift it further south for consistency with adopted corridor study and to
mitigate impacts to the CSAH 61/CSAH 15/Audubon Rd. intersection.
2. Regarding highway right of way
a. CSAH 61 at this location is a 2-lane undivided rural roadway facility with a continuous left
turn lane and no trail facilities. The existing total right of way is approximately 115 ft. with
approximately 55 ft. from centerline on the southeast side adjacent to the subject parcel.
b. The County’s 2040 Comprehensive Plan (Figure B.6) identifies typical section widths for
existing and future County highway facilities. The planned future typical section for this
highway, per corridor study, is for a 2-lane divided urban roadway with the trail on the
southeast side, which requires 65 ft. from centerline.
i. Revise the preliminary plat to incorporate a minimum of 10 ft. additional right of
way dedication adjacent to CSAH 61 from the existing right of way for a total of 65
ft. from centerline.
ii. A sight triangle right of way dedication from the required right of way dedication
for 100 feet along CSAH 61 and 80 feet along Audubon Rd. is required on the
southeast corner of the CSAH 61/CSAH 15/Audubon Rd. intersection.
iii. Right of way along Audubon Rd. should be preserved by dedication for consistency
with the CSAH 61/Audubon Rd. intersection plans as well as for any future
pedestrian facilities planned by the Cities such as a sidewalk or trail along the east
side of Audubon Rd.
3. Regarding pedestrian facilities
a. There is currently no pedestrian crossing infrastructure for the south or eastern legs of the
CSAH 61/CSAH 15/Audubon Rd. intersection adjacent to the proposed development.
i. Work with the County to install crosswalk and pedestrian traffic signal system
improvements for the southern and eastern legs of the intersection including
installation of ADA compliant curb ramp(s) at the southeast corner of the
intersection adjacent to the proposed development. An internal pedestrian
connection on the site from this corner is recommended.
4. Regarding traffic impacts
a. The memo titled Buttenhoff Industrial Trip Generation and Access dated June 30, 2021 did
not include analysis of the CSAH 61/CSAH 15/Audubon Rd. intersection.
i. Traffic operations need to be studied and reviewed for the CSAH 61/CSAH
15/Audubon Rd. intersection. Information is needed regarding the northbound left
from Audubon Rd. onto CSAH 61 to analyze the impact of the added traffic to the
intersection. Coordinate with County staff regarding traffic split assignments, trip
generation calculations, and future traffic projections to use for this analysis.
ii. Provide truck turning templates to and from CSAH 61 and for each turn lane on
Audubon Rd.
5. Regarding final approval and permitting
a. The County will need to review and approve the final grading plans adjacent to CSAH 61. A
grading permit will be required for grading work within the highway right of way.
b. The technical details of the final plat, its boundaries and form(s) will need to be reviewed
and approved by the County Surveyor.
c. Prior to any work affecting or on County highways or in County right of way, the applicant
shall coordinate plans with the County Engineer and obtain a Utility or
Excavating/Filling/Grading Permit(s) from Carver County Public Works:
(https://www.co.carver.mn.us/departments/public-works/quick-links/permits). Final
details of locations, grades, and profiles affecting County roads as well as any utility
connections will need to be reviewed and approved prior to any permits.
d. Any damages, modifications, or changes incurred on County highways from current or
approved conditions will need to remedied or updated at development expense, including
costs incurred by the County.
These are the County’s comments at this time. If you have any questions or need further assistance, please
