RAMSEY SOIL AND WATER CONSERVATION DISTRICT Mid-America Bank Building • 1827 North Soint Paul Rood • Maplewood, Minnesota 55109 Telephone 1612 777-0127 MINNESOTA lin& SOIL AND WATER CONSERVATION DISTRICTS Juane 22, 1981 To: Supervisors of Ramsey Soil and Water Conservation District Subject: Review of the Preliminary Plat Nbuands View Square for Robert Eigenheer, Owner and Developer. I. Introduction The proposed plat is located in Mounds View at the corner of County Road I and Edgewood Drive. Specifically the SW4 of southeast 34 of southwest of Section 5, TWN. 30, R23. This report inventories and evaluates the ex sting soil and water resources of the area. Where necessary suggestions are made as to how development • maybe more suitably accommodated. II. Inventory and Evaluation of Soils Zimmermml loamy fine sand 0-6% slope. This is a level to gently sloping excessively drained soil. It is found on convex knolls and side slopes of glacial outwash plains. The typical pedon consists of a surface layer 9 inches thick which is a dark grayish brown loamy fine sand. The subsurface layer is a grayish brawn loamy fine sand 6 inches thick. Underlying layers are stratified light yellowish brown to dark brown fine sands. Some areas may have a strata of medium coarse material in the underlying layers. Included in this mapping unit are small areas of moderate to poorly drained Limo soils and very poorly drained Isanti soils. The Isanti and Lino soils occur in law and depressional areas. The Zimmerman soil has rapid permeability, very slaw surface runoff and the available water capacity is low. Natural fertility is law as is organic matter content. The Zimmerman soil is well suited to building site develop- sent. Structural supportability is very good. During excavation, precaution- ary measures must be taken to prevent sidewall cave in. This is a severe problem due to the non-cohesive=ness of the sandy texture soil material. Due to excessive perk rates, this soil is poorly suited for septic systems. Zimmerman soils, when exposed, will be very prone to erode by wind action. It will be necessary to stabilize these soils as soon as possible following • rough grading. Suggestions of stabilization procedures are listed in Appendix. The seasonal high water table is below six feet of the surface. Lawns and shrubs will be difficult to establish and maintain due to low natural fertility and the sandy texture. AN EQUAL OPPORTUNITY EMPLOYER
