Re: Development / Access Review Comments: 10500 and 10520 Great Plains Boulevard
Conceptual Planned Unit Development (PUD) located at PID#s 256010010 and 256010020
adjacent to County State Aid Highway (CSAH) 101 (Great Plains Blvd.) and CSAH 61 (Flying
Cloud Dr.)
Thank you for the opportunity to review the subject development in the City of Chanhassen. Consistent
with the County Comprehensive Plan and County Codes, and other official controls of the County, the
following are comments and recommended conditions of approval and as potential requirements for any
necessary permits to be issued for the project.
1. Regarding access to the County highway
a. The proposed driveway access onto CSAH 61 was built with the County’s Flying Cloud Dr.
project and the proposed driveway location appears consistent with the access that was
constructed.
b. Provide an estimate of the maximum number of vehicles that may make a left turn into the
site during an hour to evaluate the potential operational and safety risk of vehicles and any
towed trailers obstructing eastbound CSAH 61 traffic. Additional improvements may be
needed to mitigate any operational or safety risks that are identified.
2. Regarding County highway right of way
a. The property boundaries shall match the existing County highway right of way. The
proposed boundary appears to match the highway right of way as modified by CR RW Plat
No. 29.
3. Regarding grading adjacent to the County highway
a. County requests drainage calculations and data for the proposed development. Revision is
likely needed regarding the outlet for the proposed stormwater treatment ponds, which is
not in a good location due to the flow outlet being up gradient from the trail which is
below. Drainage should be carried and directed further to the east into the roadside ditch
that currently exists instead of to the west side of the development on the steep slopes and
directly pointed at the trail embankment.
b. Confirm the proposed drainage will not create an adverse impact to the County right of
way.
c. Proposed grading shall tie-in and be compatible with the existing ground in the County
right of way.
4. Regarding final approvals and required permits -
a. The County will need to review and approve the final grading plans for properties adjacent
to CSAH 101 and CSAH 61. A grading permit will be required for grading work within the
highway right of way.
b. An access permit will be required for access to CSAH 61 due to this change in use and
connection of the site improvements to CSAH 61.
c. The technical details of any final plat, its boundaries and form(s) will need to be reviewed
and approved by the County Surveyor.
d. 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, Access, or
Excavating/Filling/Grading Permit(s) from Carver County Public Works:
(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.
e. 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
