Commission Business Chairperson Anderson called the regular meeting of the Planning Commission back to order at 8:48 p.m. This plat is in the shoreland overlay district for Lake Itasca and as such, the lots are required to be at least 80,000 square feet in' size and 200 feet wide at the road frontage or building setback line. In addition, the riparian lots or lots adjacent to the lake (4, 5 and 6) are also required to be 200 feet wide at the water frontage and provide for a 200 foot structure setback from ordinary high water mark and a septic system setback of 150 feet fi.om ordinary high water mark. All of the lots meet the shoreland regulations with one exception. Together, all of the lots total more than 1,400 feet of frontage at the street frontage or building setback lines, but on a lot by lot basis, Lot 5 is shy of the 200 foot lot width mark. A variance will be required and is being scheduled for the May Board of Adjustment. Zoning Administrator Frolik stated park dedication for this portion of the P.U.D. has been previously satisfied with land dedication. She indicated the lots are proposed to receive public access form the extension of a cul-de-sac west off of Andrie Street. The cul-de-sac length is approximately 1,000 feet and a variance 'to the 600 foot maximum dead-end street length is required and is being scheduled for the May Board of Adjustment. The preliminary plat proposes to name the street Itasca Point Road, which is a deviation from the City's grid system and requires Council approval. City Engineer Jankowski stated the Grading and Drainage Plan has been reviewed and he recommended a modification consisting of an elongated sedimentation basin on the common property lines of Lots 6 and 7. He indicated the sediment pond would need to be cleaned occasionally and stated preference that it be located near the front property line for easier access. A compromise was made between the City and the developer to require a large diameter manhole be placed before the discharge enters the pond. This would' allow an opportunity to remove larger particles and remove the need to clean the pond. Additionally, he asked that the developer be responsible to maintain the sediment pond and manhole during development, as most sediment during that time is generated fi.om the developer. He stated a 30 foot easement would be included in the plat for the sediment pond. Commissioner Johnson stated concern regarding the necessity of two variances. Dennis Peck, Northfork Developer, explained the standard house pad for the City must be 200 feet off the normal high water mark from Lake Itasca. The DNR ordinance states 150 feet is required. He stated the DNR is comfortable with the 150 foot distance and indicated Staff stated support of the request. He said Lots 4 and 5 would be able to build closer to the normal walkout grades and more trees could be saved on the lots. In terms of the cul-de-sac length, he indicated seven lots would be located there. He indicated having no problem if the Planning Commission were to postpone prelim/nary plat approval until May, 1999 in order to deal with the variance issues. Chairperson Anderson inquired if there have been previous problems with flooding on Lake Itasca. City Engineer Jankowski stated the lake level fluctuates and said there has been a seven Planning Commission/April 6, 1999 Page 11 of 13
