Anoka Soil Survey
Soil surveys are compilations of maps showing areas of different soil types on aerial photo backgrounds and text and tabular descriptions of soil characteristics bound together in a book. The Soils Survey of Anoka County was published in 1977 by the United States Department of Agriculture, Soil Conservation Service. It is no longer available in its bound format but copies of the maps and text are available for a fee through the Anoka Conservation District. Nearly all of Anoka County total land area of 272,000 acres, or 422 square miles was mapped. Approximately 10,000 acres, in the southern part, namely, the cities of Columbia Heights and Fridley, a small part of Coon Rapids, and the Village of Spring Lake Park, was excluded from this survey. The reworking of the soil during urban construction made it impractical to classify the soils. Onsite investigation is needed to determine soil characteristics in these urban areas.

General Soils Map
The general soil map shows the soil associations in Anoka County. A soil association is a landscape that has a distinctive proportional pattern of soils. It normally consists of one or more major soils and at least one minor soil, and it is named for the major soils. The soils in one association may occur in another, but in a different pattern.
A map showing soil associations is useful to people who want a general idea of the soils in a county, who want to compare different parts of a county, or who want to know the location of large tracts that are suitable for a certain kind of land use. Such a map is a useful general guide in managing a watershed, a wooded tract, or a wildlife area, or planning engineering works, recreational facilities, and community developments. It is not a suitable map for the management of a farm or field or for selecting the exact location of a road, building, or similar structure. This is because the soils in any one association ordinarily differ in slope, depth, stoniness, drainage, and other characteristics that affect their management.
