SLOPES b. Plan SOILS a. Inventory The slopes which are found in the community may be described as follows: a) 0 -6% slopes - gentle b) 6 -12% slopes - slight c) 12 -18% slopes - moderate With the exception of some escarpments which have been identified on the map, and river bluffs, there are no Slopes greater than 18% in Ramsey (Map 2, Slopes and Erosion). Erosion is a problem in the north central portion of the community which is more the result of the soil type and activity. (agriculture) than the severity of the slope. Along the Rum River, erosion problems are in evidence in an area which is best suited to woodlands. The Mississippi River is experiencing some shoreline and bank erosion, and this problem is aggravated during periods of high water. The bank erosion problem receives a lot of attention because of the concern property owners have regarding their changing shoreline. In Ramsey, because of the sandy soil, slopes of 18% or more are susceptible to erosion. Since poorly designed or constructed developments on hillsides frequently result in a substantial cost to the public, development standards are necessary to minimize this problem. Slopes which are prone to severe erosion should be protected by requiring developers to obtain a permit from the City prior to any construction, grading or filling. Development on slopes which are subject to moderate erosion will have to provide information to the building inspector indicating that proper precautions will be taken to minimize erosion during construction, and that vegetative cover will be replaced. Regarding shoreline erosion, municipal funds should be used only for problems on public lands. Actually, shoreline erosion is a very small contributor to the pollution of the river, and since stabilization projects are very expensive, municipal funds should be used only for serious problems on public land. 7. SOILS When land is designated for a particular use, it is essential that consideration be given to the limitations of the various soil types. Soils vary greatly in compo- sition, and this "variation in soil properties affects.
