The following is a map unit description from the "Soil Survey of Barnstable County, Massachusetts (Fletcher, 1993)"

Ur-Urban land. This map unit consists of nearly level to moderately steep areas where the soils have been altered or obscured by urban works and structures. Buildings and pavement cover more than 85 percent of the surface. This unit makes up about 1.4 percent (3,474 acres) of the survey area. It is mapped throughout the county. Areas are irregular in shape and range from 10 to 1,500 acres in size.

Included in this unit in mapping are many small areas where the original soil material has been disturbed by construction and areas where fill has been added. Also included are small areas of undisturbed soils. Included areas make up about 15 percent of this unit.

The soil properties and characteristics of this unit vary. Onsite investigation is needed to determine the suitability for specific uses and the limitations affecting those uses.
