Essex County Soil Survey Report - Northern Part - Non-technical Map Unit Descriptions
Map Unit: 105D - ROCK OUTCROP-HOLLIS COMPLEX, 3 TO 25 PERCENT SLOPES
ROCK OUTCROP An on-site investigation is necessary to determine suitability and limitations.
The HOLLIS component is in capability subclass 7E which has very severe limitations that make the soil unsuited to cultivation and that
restricts its use to grazing. Erosion is the main limitation.
ROCK OUTCROP can consist of up to 90 percent exposed bedrock. Most outcrops are too hard to be broken and mixed by tillage.
The HOLLIS component is well drained; water is removed readily, but not rapidly. Agronomic capability class is 7E. Depth to bedrock is
between 10 and 20 inches. The water table is normally more than 6.0 feet below the surface.
HOLLIS has severe limitation for use as a septic tank absorbtion field because of shallow depth to bedrock and slope. There is severe
limitation for local roads and streets due to shallow depth to bedrock and slope. For dwellings with basement, there is severe limitation
because of shallow depth to bedrock and slope and for small commercial buildings, there is severe limitation due to slope and shallow
depth to bedrock.
