A Preliminary Report for Phase I Studies

A developer may examine a property's soils map and have a reasonably accurate prediction of what a more detailed study will reveal. Soils maps are generally consistent with the detailed Phase I investigational studies required for industrial development.

How to Use This Resources Map

Legend. The blue button at the right of the map opens the menu for the map. You can turn the layers off and on

• Soils. The soil boundaries are faint lines enclosing various shades of green. Steeper slopes are darker. Level areas are light blue. The soil abbreviations are in black text aligned with the soil mapping unit. Turn off the other layers and click on any area to see the name of the soil.
• Streams. The blue lines indicate the named and unnamed streams. Turn on only the streams layer and click on any blue line to see the name of the stream.
• Roads. The black lines are the roads in the County. Turn off the other layers and click on any road to see its name.
• Zooming. The buttons at the top left control zooming. The + button makes details larger while the - button zooms out. Mouse wheels also zoom the image.
• Measurements. Click the small button below the + and - buttons. Click to start a measurement. Multiple clicks allow you to measure the perimeter or distance around a place on the map.
• Moving the map. Click and drag. 

About Soil Surveys

Soil Surveys have been completed for virtually all of the United States by the Natural Resources Conservation Service, an agency of the United States Department of Agriculture. The original purpose was largely to enable better planning of agricultural land uses to achieve soil conservation. Over the years, they  became steadily more important for other planning activiites for non-agricultural uses as well as for agricultural uses. The surveys are backed by many years of field observations and laboratory test results.

Soil Map Unit Symbols

The mapping symbol is a composite abbreviation of the soil name, the land slope class, and the level of erosion that has occurred. Nearly level soils have a slope class of "A." For level land, the slope class is often not shown. As slopes increase the slope class moves to very steep F and G slopes. Erosion classes generally range from 1 to 3 with erosion class 3 b3eing highly eroded. Uneroded soils may not show an erosion class.

An area of soil mapped as PkC3 would indicate a soil series named Pickwick on a moderately sloping area that has had most of the topsoil eroded. Clicking on a location will pop up a text box that shows the soil name, slope class, and erosion class. It also will indicate the typical slope within the mapping unit.
