Mr. Kenneth Peterson September 28, 1979 Page Two e o 10. The preliminary plat did not show the correct square footage of lots and lot dimensions to the nearest tenth of a foot as quired by Section 170.037C d. of the City Code. In review of drainage, it appears that Lots 1 & 2 and 13~15, Block 7 will be utilized for ponding the runoff from the north- west portion of the plat and the remaining area is proposed to be drained to the river. Discharge to the river will require a DNR Permit and a U.S. Army f~orps of Engineers Permit. The developer should also provide a grading plan for the plat. In review of the street laYout the angle formed by the intersection of Llama Street andothe street parallel to U.S. Hwy No. 10 & 169 is approximately 67 . Section 170.038C of th~ City Code limits the angle of intersections to a minimum of 70~. Also Armstrong Boulevard N.W. does not have ~ tangent of 100 feet in length between reverse curves as required by City Code. As previously mentioned, the 142nd Avenue and 144th Avenue cul-de-sacs will require a variance for length. As previously mentioned it is still questionable if all the lots contain 25% area of CoNt~guoU~ Class I land required for on-site sewage ~isposal systems. Ten soil borings were made in the vicinity of Lots 9 & 10, Block 9; however no elevations or locations of those borings were provided. Also the requirements of Section 170.038H of the CityCode have not been complied with. As requested in our August 29, 1979, letter, no comments from MN/DOT concerning the proposed accesses and traffic controls have been received. If the Llama Street N.W. access is to be maintained its upgrading should be done in conjunction with this plat. As you are aware a portion of the plat is within Mississippi River Corridor Critical Area and subject to the Critical Area Interim Develop- ment Regulations.
