Re: Oak Park Heights Annexation Area Surface Water Management Plan
City of Oak Park Heights/Valley Branch Watershed District
This letter is in response to your recent correspondence concerning a request for information on
your Water Management Plan. The original request, dated April 1, 1996, was made by facsimile in
the form of a transmittal letter to Dan Edgerton of Bonestroo, Rosene, Anderlik & Associates. Our
engineer spoke with Mr. Edgerton within one week of this request and was told that this would be
discussed with Joe Anderlik and a response would be sent addressing the Watershed District's
concerns. Our engineer also informed Mr. Edgerton that this was not an urgent issue. We
received a response from Bonestroo & Associates on July 22, 1996.
The concerns the District has with the city's Water Management Plan are the proposed outletting
of landlocked areas to the Cloverdale Lake watershed and the increase shown in the predicted
100 -year flood elevation for the "South Pond" on the Stillwater High School property.
The city's Water Management Plan indicates the need for outlets from two landlocked areas which,
prior to downstream development, appeared to be tributary to McDonald Lake if an overflow were
to occur. Mr. Edgerton has indicated in his response that "it is prudent to provide outlets in the
event that they (these areas.) someday develop." At this time, the District would deny a request to
J
outlet these areas to the Cloverdale Lake waters e ue o the current re. evel of tioverdale Lake,
Secondly, the revised 100 -year flood elevation for the South Pond on the Stillwater High School
site has been increased to either elevation 922.1 or 921.5 (from 921.0), dependent on the outletting
of landlocked areas discussed above. This change appears to be primarily due to area once
assumed to be directly tributary to Cloverdale Lake being diverted to the South Pond prior to
discharging to Cloverdale Lake. Since this most likely will not change the amount of runoff
reaching Cloverdale Lake, the District can propose a revision of the 100 -year flood elevation to
921.5. However, permission will be required from the riparian property owners before the District
can adopt a new flood level. Please inform me if you would like the District to formally pursue
this revision.
