When used in this article, the following terms shall have the meanings herein ascribed to them, unless the context clearly requires otherwise:
BLUFF. An elevated segment of the Lake Michigan shoreline above the beach which normally has a precipitous front inclining steeply on the lakeward side.
CANTILEVER. Any portion of a principal structure that extends laterally beyond the foundation that supports it.
DIRECTOR OF PUBLIC WORKS OR DIRECTOR. The Village of Glencoe's Director of Public Works or his/her appointed designee.
DEVELOPMENT. Any man-made change (other than maintenance of existing structures, paved areas, or utilities) to improved or unimproved real estate, including without limitation the construction or installation of new, or enlargement or demolition of existing, structures, paved areas, or utilities; dredging, filling, drilling, mining, grading, paving, or excavation operations; and open storage of equipment or materials.
RAVINE. A deep gully or gorge worn by the flow of water to Lake Michigan.
SLOPE IMPACT AREA. For a lot that includes or is adjacent to a bluff or ravine, that portion of the lot lying between:
(1) The toe line of such bluff or ravine, and
(2) The line representing the intersection of the table land (or if no such intersection, the table land extended) of such lot with a 22 degree slope (2.5H:1V ratio) extending upward from the toe of bluff or ravine. For any lot that lacks table land, for the purpose identifying the slope impact area, the Director shall utilize the horizontal projection of the street line of the lot as the table land. In addition, the slope impact area also includes the area of the lot where the slope of the lot is steeper than 5.7 degrees (10H:1V ratio).
SLOPE TRANSITION AREA. That portion of the slope impact area of a lot lying outside the steep slope zone.
STEEP SLOPE LINE. A line representing the intersection of the table land (or if no such intersection exists, the table land extended) with a 27 degree slope (2H: 1V) extended upward from the toe of a bluff or ravine. For any lot that lacks table land, for the purpose identifying the steep slope line, the Director shall utilize the horizontal projection of the street line of the lot as the table land.
STEEP SLOPE ZONE. That portion of the slope impact area of a lot that lies between the steep slope line and the toe line.
STREET LINE. The street line as defined in the zoning code.
TABLE LAND. Land at the top of a bluff or ravine where the slope is less than a 5.7 degree slope (10H:1V ratio)
TOE OR TOE LINE OF BLUFF AND RAVINE. The toe of the ravine or bluff slope is that point in the ravine or bluff where the slope is less than a 5.7 degree slope (10H:1V) or where the slope reverses direction. On compound slopes where there may be more than one possible toe location, the controlling point shall be whichever toe that provides the greatest slope impact area. In plan view, the toe of bluff or ravine is depicted as continuous line, and is referred to as the toe line.
