§ 30.55.030. Definitions.

A.

For purposes of this Chapter, the following definitions shall apply:

1.

Coastal Bluff shall mean a steep escarpment with a slope gradient equal to or greater than an average of one foot vertical to one foot horizontal and a vertical rise of 15 feet or more, and which is located in an area that is periodically subject to ocean wave action.

2.

Coastal Bluff Top shall mean the top edge of a coastal bluff as delineated using the following criteria:

a.

In cases where the coastal bluff involves a series of stepped vertical and horizontal planes, the bluff top shall be considered to start at the seaward edge of the topmost riser of the vertical plane of the coastal bluff.

b.

In cases where the coastal bluff edge is composed of a continuous, rather than stepped, downward slope, the bluff top shall be considered to start at that point nearest the bluff, seaward of which the downward gradient of the land surface increases more or less continuously at an angle which is more vertical than horizontal until it reaches the general gradient of the bluff.

3.

Top Edge of Coastal Bluff shall mean the same as "Coastal Bluff Top."

4.

Principal Structure shall mean a building or structure in which the primary use of the lot on which the building is located is being conducted.

5.

Accessory Structure shall mean structures accessory or incidental to the principal structures on lot including, but not limited to, pools, spas, storage sheds, gazebos, and above-grade decks or patios.
