- Minutes of Regulsr Council Meeting Sept. 13, 1982 Page Three Case No. 82-12, Minor Subdivision, Lots 1 and 2 Block 3, Arden Hills No. 2 - John Sullivan Council was referred to letter from Engineer Christoffersen (9- 10-82) and to transparencies of proposed grading plan alternates, with access to Forest Lane and access to Skiles Lane, . Miller noted that about 11 acres drain to the low area of the prop- erty to an existing 18" culvert that carries the drainage under Skiles Lane and controls the ponded water elevation; noted that if this culvert were replaced by a 24" culvert, it appears that the acre feet of storage needed for ponding could be reduced, without seriously affecting downstream properties. Miller noted that the Engineer recommends that a portion of the area be reserved for drainage, indicated as "drainage easement" on drawing (attached to letter of 9-10-82), if a lot split is approved; noted that if the culvert is to be replaced by a 24" culvert, Christoffersen recommends that drainage easements be re- served for flowage ways through the property. Miller noted that some land modification will be necessary in order to build on the proposed lot; straightening the line between the two lots would be advantageous; noted that a variance would probably be needed to accommodate a building site; suggested that it appears the only reasonable way to build would require encroach- ment upon the Snelling Ave. setback (setback line is about 140' from centerline of Snelling Ave.). Sullivan said he has already paid quite a bit to resolve the sit- uation; does not feel he should be required to share in cost of the culvert replacement; has been tolerating the situation for 20 years; feels the drainage should have been carried down Snelling Ave., not across his property. It was noted that the lots, as platted, apparently have sufficient building sites; the fact that the existing house encroaches on both lots is the reason the applicants are proposing to re-sub- divide the property to create another lot for development. In discussion, it was noted that it appears there are ways of modifying the contours and culverts to provide adequate water storage; cost of these modifications was a concern. It was sug- gested that the lot split be deferred until a definite proposal for development of the land is submitted; loss of existing veg- etation was also a concern. Sullivan explained that he would like to create a future building site, can't read the future and has no plans for development of the property; noted that access to the proposed lot from Skiles Lane is not his choice, prefers access from Snelling or Forest Lane. Miller noted that topography indicates the best access is from Snelling; another variance, however, for access from the "collective" street rather than the "local"street would be needed. . In discussion, the following concerns were expressed by Council: 1. It appears earth can be displaced to create a building pad on the proposed lot, but this would totally change the lot. 2. A larger culvert would reduce the amount of water reten- tion on the lot; site always has been low; streets benefit the property, but also cause more run-off. 3. As subdivided, there is no drainage problem for build- ing sitea on the Iota; hesitant to approve a re-subdivision which creates a lot with definite "hard- ships". 4. If culvert is replaced by a 24" culvert, the drainage is not a problem; as it exists there is a problem in a 100 year storm, a problem against which properties should be protected. -3-
