Dear Mr. Couri:
At the request of the City of Albertville, SEH has prepared a summary of issues to be resolved by the
developer for the residential portion of the Prairie Run project.
After several recent rainfall events, it has been discovered the grading plan for the site does not
account for the 100-year flood elevation (calculated at 951.5 by Wright County) of an existing box
, culvert where County Ditch No. 9 passes under Jason Avenue. The location of the box culvert is in
the southwest corner of the development and County Ditch No. 9 is the outlet for storm water runoff
from the site.
Using the 100-year flood elevation calculated by Wright County, we have determined there are a
number of lots in the Prairie Run development that do not comply with the City's ordinance requiring
that the lowest opening elevation of a building be at least 2 feet above the 100-year flood elevation.
The lots that do not comply are Lots 5-28 and Lots 33-34 of Block 2. Of the lots identified, Lots 7,
14-16, 18-20, 22, and 26-28 of Block 2 have houses which either are finished or are under
construction.
The City is requesting resolution of the following issues:
1. For all lots that are currently vacant and that do not comply with the ordinance, a revised grading
plan must be prepared by the developer and submitted for City review and approval. The City
will not issue any new building permits until this condition is met.
2. For all non-complying lots where a building permit has been issued but a certificate of occupancy
has not been issued, the developer shall submit a mitigation plan to bring the buildings into
compliance with the City ordinance.
3. For all non-complying lots where a certificate of occupancy has been issued, the developer shall
submit a mitigation plan to bring the buildings into compliance with the City ordinance.

As an alternative to mitigating existing non-compliance, Albertville staff has discussed that the
Wright County's 100 year flood elevation may be a very conservative elevation considering it did not
include any storm water ponding or reflect the City's 50% post run-off requirement. The City of
Albertville would entertain the Developer financing a study to have the City Engineer verify the
County's 100 year flood elevation or determine a new 100 year flood elevation for this area. A
preliminary estimate for this study is $7,500. In lieu of depositing these funds the City would also
accept a letter extending the Developer's Letter of Credit on file to secure payment for this study.
Please prepare a letter notifying Gold Key Development and their engineer, Hedlund Engineering, of
these issues and of their obligation to resolve them.
Please call me at 651.490.2147 if you have questions.
Sincerely,
Robert L. Moberg, PE
Project Manager
