Box 66 Orono, MN 55356 Crystal Bay, MN 55323-0066 October 16, 1998 George & Katherine Kalweit 4265 Forest Lake Drive Mound MN 55364 Dear Mr. & Mrs. Kalweit; This letter is in response to your letter, to Mayor Jabbour, regarding drainage problems on your property. We have researched the files at City Hall, and there is much previous correspondence regarding these issues. This area was originally subdivided in 1958. A reasonable assumption is that the streets and storm sewer were constructed, at that time, before the first houses were built. According to the County tax records the present house on your property was constructed in 1970, and you purchased the property in 1992, thirty-four years after the pipe was installed. Regarding the existing storm sewer pipe and no easements for this pipe, this is typical for improvements that were constructed then. Standards and requirements for subdivisions and construction projects were less stringent then. This pipe has been in use for forty years, is necessary for drainage of the subdivision, and is allowed to remain based on the long history of continuous use. The storm drainage pipe is located in the lowest portion of the area that has historically been a drainage path for water into Forest Lake. Rerouting or removal of this pipe is not possible. According to your letter,a large cottonwood tree blew down during the May 15th severe windstorm. Hundreds of trees in the City were blown down during this severe windstorm, so this tree blowing down was not a unique occurrence. The tree was located in a low area next to the lake. Soft ground and ponded water would be expected to be found in this area. The drainage area for the storm water pipe is about ten acres and basically includes the Forest Arms Country Club Subdivision. The storm water from the subdivision properties is affecting the lakeshore and joint dock area. Because the problem is being caused by drainage from the subdivision, and correction of problem would benefit the subdivision property owners, the costs of any project to solve the drainage problems should be assessed to the properties in the drainage area. Telephone (612) 473-7357 • FAX 473-0510 � • .� . A preliminary review suggests that the most feasible solution would be to construct a sedimentation pond on the area of the joint dock lot next to the existing storm drainage pipe. This should reduce the amount of sediment reaching the lake. Correction of the existing sedimentation problem will require dredging of the lake to remove the sediment deposits. The feasibility of dredging the lake from both a cost and regulatory perspective, needs to be investigated further. The next step in this process would be for the subdivision residents to submit a written petition to the City requesting that the we proceed with implementing an assessment project. Upon receipt of a petition, the City Council then orders the preparation of a feasibility study to determine the feasibility of and estimated costs for a project. After completion of the feasibility study, a public hearing is held by the City Council. If sufficient interest in the project is expressed at the public hearing, the Council will then order preparation of plans and specifications and bidding of the project. After bids are received the Council will hold an assessment hearing before awarding of the construction contract. Thank you for your assistance in this matter. Please contact me should you have any questions or comments regarding this project. Sincerely; _ �f�.-G{ a � Gregory A.
