Mr. Kenneth Peterson August 29, 1986 Page Two Soil borings and soil classifications were not submitted as required by Article 170.037B.i. of the City Code to determine the elevation of the water table. However, based on the Anoka County soil survey, the soils consist of Nymore loamy sand and Sartell fine sand and Alluvial soils along the river. Nymore loamy sand and Sartell fine sand are Class I soil suitable for on-site wastewater disposal systems. However, Lots 3, 6 and 16 do not appear to have adequate Class I soils suitable for on-site wastewater disposal systems. We would also recommend soil borings be provided for the plat to determine the water table. In review of drainage, the grading plan and street plans indicate four drainage outlets to the river. Calculations should be provided to assure that the storm sewers are adequate. In addition, the proposed storm sewers should be reviewed to make sure erosion is not a problem. Access to the plat is provided by 153rd Avenue N.W., Juniper Ridge Drive and Roanoke Street. Roanoke Street is a Municipal State Aid Road and under current City Policy this street would be constructed with State Aid funds. However, a forty feet wide easement along the west side of the plat should be provided to allow for the future construction of Roanoke Street. We would not recommend approval of the plat until the DNR concerns in their letter of August 22, 1986 are met and the items in this letter are complied with or variances are granted. If you have any questions in regard to the preliminary plat, please let us know. Yours truly, HAKANSON ANDERSON ASSOCIATES, INC. Peter R.
