Metropolitan Council Referral File No. 11988-1. Our office did not receive sufficient information, such as plat plaa~ etc. to effectively examine and review this project. We can and will briefly outline the natural soil limitations of the soils on the site with respect to home construction. :~ A little less than 50% of the parcel has soils with a natural high water table of 0-5' depth. There are five separate areas of classified marsh. Areas of marsh naturally have standing water 1-3' deep year round, with underlying soils that are unstable, low soil strength and unsuitable for construction, unless excavated, removed and suitable so~_ls filled in. These marsh areas act as a sponge for collecting surrounding surface water. Marsh areas are commonly impractical to drain. A table of soil limitations with respect to home construction, 'taken from the Anoka County Soil SurveY, is as follows: Dp - Duelm loamy coarse sand DnA - Dickman sandy loam, 2-~ slope Iw- Isanti fine sandy loam Hu A, B, C - Hubbard coarse sand O-2%o slope 2-~ slope 6-12% slope Mc - Marsh Ny A, C -Nymore loamy sand 0-2% (Please see chart next page) AN EQUAL OPPORTUNITY EMPLOYER
