All definitions in this section shall apply to the department and to port districts managing aquatic lands under a management agreement (WAC 332-30-114). For the purpose of this chapter:

(1) "Accretion" means the natural buildup of shoreline through the gradual deposit of alluvium. The general principle of common law applicable is that a riparian or littoral owner gains by accretion and reliction, and loses by erosion. Boundary lines generally will change with accretion.

(2) "Alluvium" means material deposited by water on the bed or shores.

(3) "Anniversary date" means the month and day of the start date of an authorization instrument unless otherwise specified in the instrument.

(4) "Aquaculture" means the culture and/or farming of food fish, shellfish, and other aquatic plants and animals in fresh water, brackish water or salt water areas. Aquaculture practices may include but are not limited to hatching, seeding or planting, cultivating, feeding, raising, harvesting of planted crops or of natural crops so as to maintain an optimum yield, and processing of aquatic plants or animals.

(5) "Aquatic lands" means all state-owned tidelands, shorelands, harbor areas, and the beds of navigable waters (RCW 79.105.060(1)). Aquatic lands are part of the public lands of the state of Washington (see subsection (51) of this section). Included in aquatic lands are public places subsection (53) of this section, waterways subsection (78) of this section, bar islands, avulsively abandoned beds and channels of navigable bodies of water, managed by the department of natural resources directly, or indirectly through management agreements with other governmental entities.

(6) "Aquatic land use classes" means classes of uses of tideland, shorelands and beds of navigable waters that display varying degrees of water dependency. See WAC 332-30-121.

(7) "Authorization instrument" means a lease, material purchase, easement, permit, or other document authorizing use of state-owned aquatic lands and/or materials.

(8) "Avulsion" means a sudden and perceptible change in the shoreline of a body of water. Generally no change in boundary lines occurs.

(9) "Beds of navigable waters" means those submerged lands lying waterward of the line of extreme low tide in navigable tidal waters and waterward of the line of navigability in navigable lakes, rivers and streams. The term, "bedlands" means beds of navigable waters.

(10) "Commerce" means the exchange or buying and selling of goods and services. As it applies to aquatic land, commerce usually involves transport and a land/water interface.

(11) "Covered moorage" means slips and mooring floats that are covered by a single roof with no dividing walls.

(12) "Department" means the department of natural resources.

(13) "Dredging" means enlarging or cleaning out a river channel, harbor, etc.

(16) "Environmental reserves" means areas of environmental importance, sites established for the continuance of environmental baseline monitoring, and/or areas of historical, geological or biological interest requiring special protective management.

(17) "Erosion" means the gradual cutting away of a shore by natural processes. Title is generally lost by erosion, just as it is gained by accretion.

(18) "Extreme low tide" means the line as estimated by the federal government below which it might reasonably be expected that the tide would not ebb. In Puget Sound area generally, this point is estimated by the federal government to be a point in elevation 4.50 feet below the datum plane of mean lower low water, (0.0). Along the Pacific Ocean and in the bays fronting thereon and the Strait of Juan due Fuca, the elevation ranges down to a minus 3.5 feet in several locations.

(19) "Fair market value" means the amount of money which a purchaser willing, but not obligated, to buy the property would pay an owner willing, but not obligated, to sell it, taking into consideration all uses to which the property is adapted and might in reason be applied (Donaldson v. Greenwood, 40 Wn.2d 238, 1952). Such uses must be consistent with applicable federal, state and local laws and regulations affecting the property as of the date of valuation.

(20) "First class shorelands" means the shores of a navigable lake or river belonging to the state not subject to tidal flow, lying between the line of ordinary high water and the line of navigability, or the inner harbor line where established and within or in front of the corporate limits of any city, or within two miles thereof upon either side (RCW 79.105.060(3)). These boundary descriptions represent the general rule; however exceptions do exist. To determine if the shorelands are within two miles of the corporate limits of a city, the distance is measured along the shoreline from the intersection of the corporate limit with the shoreline.

(21) "First class tidelands" means the shores of navigable tidal waters belonging to the state lying within or in front of the corporate limits of any city, or within one mile thereof upon either side and between the line of ordinary high tide and the inner harbor line; and within two miles of the corporate limits on either side and between the line of ordinary high tide and the line of extreme low tide (RCW 79.105.060(4)). In general, the line of ordinary high tide is the landward boundary. The line of extreme low tide, or the inner harbor line where established, is the waterward boundary. To determine if the tidelands are within two miles of the corporate limits of a city, the distance is measured along the shoreline from the intersection of the corporate limit with the shoreline.
