Wetlands are areas that are inundated or saturated by surface water or groundwater 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 from nonwetland areas created to mitigate conversion of wetlands.
A.
All areas within the city of Newport meeting the wetland designation criteria in the approved federal wetland delineation manual and applicable regional supplements, as amended, regardless of any formal identification, are hereby designated critical areas and are subject to the provisions of this chapter.
1.
Wetlands shall be rated according to the Washington Department of Ecology Wetland Rating System, as set forth in the Washington State Wetland Rating System for Western Washington: 2014 Update (Ecology Publication No. 14-06-029), or as revised and adopted by the city.
2.
A buffer area shall be established for all designated wetlands to protect the function and values of the wetland.
3.
For more information on the rating of wetlands as well as the criteria and standards for establishing buffer areas, please refer to the city of Newport Critical Areas Manual.
B.
No development activities or new uses may be permitted on sites that meet the criteria for designation as a wetland or an associated buffer without a critical areas authorization or critical areas permit in accordance with the provisions of this chapter.
1.
The following uses and activities may be permitted by the city in wetlands through a critical areas authorization:
a.
Conservation or preservation of soil, water, vegetation, fish, and other wildlife that does not entail changing the structure or functions of the existing wetland.
b.
The harvesting of wild crops in a manner that is not injurious to natural reproduction of such crops and provided the harvesting does not require tilling of soil, planting of crops, or alteration of the wetland by changing existing topography, water conditions or water sources.
c.
Recreational and educational activities.
e.
Drilling for utilities under a wetland; provided, that the drilling does not interrupt the groundwater connection to the wetland or percolation of surface water down through the soil column. The city may require the project sponsor to submit a special study prepared by a qualified professional to determine whether the groundwater connection to the wetland or percolation of surface water down through the soil column is disturbed prior to any drilling or drilling associated activities.
f.
Enhancement of a wetland through the removal of nonnative invasive species. Weeding shall be restricted to hand removal and weed material shall be removed from the site. Bare areas that remain after weed removal shall be revegetated with native shrubs and trees at natural densities. Some hand seeding may also be done over the bare areas with native plants.
