wetland, local government shall consider the "Federal Manual for 

 Identifying and Delineating Jurisdictional Wetlands", 

 cc. "Regulated Activities" means any of the following activities 

 which are directly undertaken or originate in a regulated wetland 

 or its buffer: 



1) The removal, excavation, grading, or dredging of soil, sand, 

 gravel, minerals, organic matter, or material of any kind; 



2) The dumping, discharging, or filling with any material; 



3) The draining, flooding, or disturbing of the water level or 

 water table; 



4) The driving of pilings; 



5) The placing of obstructions; 



6) The construction, reconstruction, demolition, or expansion of 

 any structure; 



7) The destruction or alteration of wetlands vegetation through 

 clearing, harvesting, shading, intentional burning, or planting 

 of vegetation that would alter the character of a regulated 

 wetland, provided that these activities are not part of a forest 

 practice governed under chapter 76.09 RCW and its rules; or 



8) Activities that result in a significant change of water 

 temperature, a significant change of physical or chemical 

 characteristics of wetlands water sources, including quantity, or 

 the introduction of pollutants. 



dd. "Repair or maintenance" means an activity that restores the 

 character, scope, size, and design of a serviceable area, 

 structure, or land use to its previously authorized and undamaged 

 condition. Activities that change the character, size, or scope of 

 a project beyond the original design and drain, dredge, fill, 

 flood, or otherwise alter additional regulated wetlands are not 

 included in this definition. 



ee. "Scrub-shrub wetland" means a regulated wetland with at least 

 30 percent of its surface area covered by woody vegetation less 

 than 20 feet in height as the uppermost strata, 

 ff. "Serviceable" means presently useable. 



gg. "Unavoidable and necessary impacts" are impacts to regulated 

 wetlands that remain after a person proposing to alter regulated 

 wetlands has demonstrated that no practicable alternative exists 

 for the proposed project. 



hh, "Water-dependent" means requiring the use of surface water that 

 would be essential to fulfill the purpose of the proposed project, 

 ii" "Wetlands," for the purposes of inventory, incentives, and 

 nonregulatory programs, means those lands transitional between 

 terrestrial and aquatic systems where the water table is usually at 

 or near the surface or the land is covered by shallow water. For 

 the purposes of this definition, wetlands must have one or more of 

 the following attributes: 



1) At least periodically, the land supports predominantly 

 hydrophytes ; 



2) The substrate is predominantly undrained hydric soil; and 



3) The substrate is nonsoil and is saturated with water or 

 covered by shallow water at some time during the growing season 

 of each year.
