means a recreational use, or other use facilitating public access to the shoreline; or uses that cater to recreational, cultural, educational, tourism, food and drink services, hotel, and water-related retail promoting the recreational use or aesthetic enjoyment of the shoreline for a substantial number of people as a general characteristic of the use.

means all areas of tidelands and uplands lying above and within two hundred feet of the line of ordinary high tide. In the OS, DB and WMU zones the waterfront area is further defined as lying between the Burlington Northern's railroad tracks and line of extreme low tide, extending south to the southern boundary of Mukilteo Lighthouse Park and extending east to the east boundary of the city.

means the line of the ordinary high water mark (OHWM).

means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including but not limited to irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created to mitigate conversion of wetlands.

means a naturally vegetated and undisturbed, enhanced or revegetated zone surrounding a natural, restored or newly created wetland that is an integral part of a wetland ecosystem, and protects a wetland from adverse impacts to the integrity and value of a wetland. Wetland buffers serve to moderate runoff volume and flow rates; reduce sediment, chemical nutrient and toxic pollutants; provide shading to maintain desirable water temperatures; provide habitat for wildlife; and protect wetland resources from harmful intrusion.

means a description of a wetland system based on the classification system used in the most current edition of the Washington State Wetlands Rating System—Western Washington, prepared by the Washington State Department of Ecology.

means "wetland category" for the purposes of these regulations.

means an action to intentionally establish a wetland or a portion of a wetland where one did not formerly exist.

means identification of wetlands and delineation of their boundaries pursuant to this chapter, done in accordance with the approved federal wetland delineation manual and applicable regional supplements. All areas within the city meeting the wetland designation criteria in that procedure are hereby designated critical areas and are subject to the provisions of Chapter 17.52B.

means a report prepared by a qualified wetland specialist or city staff that identifies and characterizes wetlands consistent with applicable provisions of this chapter. A determination does not include a formal delineation.

means the alteration of an existing wetland or habitat to improve or increase its characteristics and processes without degrading other existing functions. Enhancements are to be distinguished from wetland creation or restoration projects.

means the beneficial biological, physical, and other purposes generally served by wetlands, including but not limited to helping to maintain water quality, storing and conveying stormwater and floodwater, recharging ground water, providing wildlife habitat, and service as areas for recreation, education, scientific study and aesthetic enjoyment.

means the effect of any human-induced alteration to the wetland and surrounding buffer, and includes impacts on any downstream anadromous fish.

means to mitigate impacts to wetlands away from the site on which a wetland has been adversely impacted by a regulated activity.

means to mitigate impacts to wetlands at or adjacent to the site on which a wetland has been adversely impacted by a regulated activity within the same watershed.

is the action to reestablish a wetland in an area which was historically wetland but which does not now provide or contain the necessary functional characteristics.

is a person who has earned a minimum of a bachelor's degree in biology, natural resources, or physical sciences with specific or related course work in wetland ecology, botany, or soils science from an accredited college or university, and two years professional experience in wetland delineation, wetland functional assessment and mitigation techniques or equivalent experience; or any person certified by the U.S. Army Corp of Engineers or Society of Wetland Scientists.

means the sale of goods in relatively large quantities at a reduced price to retailers.

means a report, prepared by a qualified consultant, that evaluates plant communities and wildlife functions and values on a site, consistent with the format and requirements established by this chapter.

means one or more rods, panels, discs or similar devices used for the transmission or reception of radio frequency signals through electromagnetic energy, which may include omni-directional antenna (whip), directional antenna (panel), and parabolic antenna (dish).

means any unstaffed facility for the transmission and/or reception of wireless communications services, usually consisting of an antenna array, transmission cables, equipment facilities, and support structure.

means a wireless communication facility that is affixed to an existing structure, utility pole, traffic light, or water tower.

means any wireless communication facility that is independent of any existing structure, utility pole, traffic light, or water tower.

means a nonpermanent facility installed on a short-term basis, for the purpose of evaluating the technical feasibility of a particular site for placement of a WCF or for providing emergency communications during a natural disaster or other emergency. Examples of temporary WCFs include, but are not limited to, placement of an antenna upon a fully extended bucket truck, crane, or other device capable of reaching the height necessary to evaluate the site for placement of a WCF.

means a structure designed and constructed specifically to support an antenna array, and may include a monopole, self-supporting tower, guy-wire support tower, and other similar structures.

means any personal wireless services as designated in the Federal Telecommunications Act of 1996, which includes FCC-licensed commercial wireless telecommunications services including cellular, personal communications services, specialized mobile radio, enhanced specialized mobile radio, paging, and similar services that currently exist or that may in the future be developed.

means the required open space in front, rear, or side on the same lot with a building or proposed building.

means the required open space extending from the principal street line to the building line and including the full width of the lot to its side lines. On corner lots the front yard is the yard upon which the principal building fronts.

means the required open space extending from the rear lot line to the main building line and including the full width of the lot to its side lines.

means the required open space extending from the front yard to the rear yard and from the main building to the side lot line.

means an area accurately defined as to boundaries and locations on the official zoning map and within which area only certain types of land uses are permitted.
