MEMORANDUM

SUBJ:
High School Retaining Wall
Attached please find a letter from Steve Pumper from School District 112
regarding the large retaining wall along the bus entrance to the new high school.
When this project was approved, the Council required that, "the applicant and
city staff look at reasonable alternative designs to reduce the impact of the
retaining walls."
The School District received a quote for a two-tier structure; however, the cost
difference between a one-tier and two-tier wall is $123,400. The School Distlict
is therefore requesting that they be allowed to proceed with the one-tier wall
design.
If there are no objections from the City Council, staff will issue the one-tier wall
permit based on the demonstrated cost increase and their intent to "break up" the
expanse of the wall with trees, vegetation, and vines.
The City of Chanhassen · A growing community with clean lakes, quality schools, a chanming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

Todd,
This letter is a follow up to our phone conversation regarding one of the retaining walls on the
Chanhassen High School site. Per discussion by the Chanhassen City Council during the
permitting process, the Council preferred the School District look at the possibility of reducing
the perceived height of a retaining wall adjacent to the entry road that leads out to Audubon. It
was suggested that the wall be made into a two-tier structure. The District agreed to try to change
the design, given both the limited amount of available land since it is extremely close to the wet-
land buffer zone, and the probability of added expense. It was my understanding that night that
while the Council wished for change to occur, it was also communicated that it needed to stay
within reasonable redesign and cost limits.
It appears that we are able redesign the wall in such a fashion that can stay within the available
land restrictions. However, after receiving the attached Proposal Request from Rosti
Construction, the contractor awarded the retaining wall contract, it appears to be cost prohibitive
to make this change. Rosti Construction indicates it would add $123,400 to its contract to change
the wall to a two-tier style. The District does not believe this cost justifies the added aesthetic
benefit that would be gained by making this change.
Per discussions we have had in the past, we will continue to "break up" the expanse of our
retaining walls with trees, vegetation, and vines. We hope this will be an acceptable solution.
If you have any questions, please feel free to call me at 952-556-6261.
Sincerely,
~"I~
