and hydrologic characteristics to identify areas meeting the wetland identification criteria, and (2) <br /> mapping wetland boundaries using aerial photography and existing survey information. <br /> The following criteria descriptions were used in the boundary determination: <br /> 1.) Examination of the site for hydrophytic vegetation (species present and percent cover); <br /> 2.) Examination of the site for hydric soils; <br /> 3.)Determining the presence of wetland hydrology <br /> The following criteria must be met in order to make a positive wetland determination: <br /> Vegetation Criteria <br /> The Corps Manual and 2010 Regional Supplement define hydrophytic vegetation as "the <br /> assemblage of macrophytes that occurs in areas where inundation or soil saturation is either permanent or of <br /> sufficient frequency and duration to influence plant occurrence." Field indicators are used to determine <br /> whether the hydrophytic vegetation criteria have been met. Examples of these indicators include, <br /> but are not limited to, the rapid test for hydrophytic vegetation, a dominance test result of greater <br /> than 50%, and/or a prevalence index score less than or equal to 3.0. <br /> Soils Criteria <br /> The 2010 Regional Supplement(per the National Technical Committee for Hydric Soils) defines <br /> hydric soils as soils "that formed under conditions of saturation,flooding or ponding long enough during the <br /> growing season to develop anaerobic conditions in the upper part." Field indicators are used to determine <br /> whether a given soil meets the definition for hydric soils. Indicators are numerous and include, <br /> but are not limited to, presence of a histosol or histic epipedon, a sandy gleyed matrix, depleted <br /> matrix, and redoximorphic depressions. <br /> Hydrology Criteria <br /> Wetland hydrology encompasses all hydrologic characteristics of areas that are periodically <br /> inundated or have soils saturated to the surface for a sufficient duration during the growing <br /> season. Areas with evident characteristics of wetland hydrology are those where the presence of <br /> water has an overriding influence on the characteristics of vegetation and soils due to anaerobic <br /> and chemically reducing conditions, respectively. The strongest indicators include the presence of <br /> surface water, a high water table, and/or soil saturation within at least 12 inches of the soil <br /> surface. <br /> 4.2 BOUNDARY DETERMINATION FINDINGS/RESULTS <br /> One wetland was identified and delineated on the subject site. A previous delineation was <br /> performed and the boundary does not appear to have changed. The boundary was not re- <br /> surveyed. The wetland was rated pursuant to the Washington State Wetland Rating System for Western <br /> Washington (Hruby 2014), which is consistent with section 19.37.090(C) of the City of Everett <br /> Municipal Code (EMC). <br /> The wetland is a slope wetland per the HGM classification system (Brinson 1993), with the main <br /> source of hydrology being groundwater from side slope seeps. <br /> View Ridge Community Church 3 Critical Area Report and Buffer <br /> WM.#16092 Averaging/Enhancement Plan <br /> November 21, 2016 <br />
