According to NRCS Web Soil Survey, the subject property is underlain by Alderwood Gravelly <br />Sandy Loam, 15 to 30 percent slopes. <br />Alderwood Gravelly Sandy Loam, 15 to 30 percent slopes (AgD), is made up of moderately well <br />drained soils that have a weakly consolidated substratum at a depth of 24 to 40 inches. In a <br />representative profile, the surface layer and subsoil are very dark brown, dark brown, and grayish <br />brown gravelly sandy loam about 27 inches thick. The substratum is grayish -brown, weakly <br />consolidated to strongly consolidated glacial till that extends to a depth of 60 inches and more. <br />Soils included with this soil snapping make up no more than 30 percent of the total acreage. Some <br />areas are up to 25 percent Everett soils that have slopes of 15 to 30 percent, and some areas are up <br />to 2 percent Bellingham, Norma, and Seattle soils, which are in depressions. Runoff' is medium, <br />and the erosion hazard is severe. <br />2.1.3 Hydrology Criteria <br />The 2010 Regional Supplement defines wetland hydrology as "areas that are inundated (flooded <br />or ponded) or the water table is less than or equal to 12 inches below the soil surface for 14 or more <br />consecutive days during the growing season at a minimum frequency of 5 years in 10." During the <br />early growing season, wetland hydrology determinations are made based on physical observation <br />of surface water, a high water table, or saturation in the upper 12 inches. Outside of the early <br />growing season, wetland hydrology determinations are made based on physical evidence of recent <br />inundation or saturation (i.e. water marks, surface soil cracks, water -stained leaves). <br />Weather and Precipitation Analysis <br />Weather conditions during the December 16, 2020 site visit were overcast with a high temperature <br />of 49°F, and 0.34 inches of precipitation was recorded for that 24-hour period (Everett Snohomish <br />County AP station). <br />Monthly totals, and departure from normal precipitation data were collected from the Everett <br />Snohomish County AP station (via AgACIS for Snohomish County) for the three months <br />preceding the December site visit. According to the Everett station data, monthly precipitation <br />totals fall within "normal" range for the December site visit (see Figure 2). <br />Long -Term Rainfall Records <br />Month <br />Normal/ <br />Average <br />30% Chance Will Have <br />Observed <br />Precipitation <br />Condition (Dry, <br />Normal, Wet) <br />Condition <br />Value* <br />Month Weight <br />Value <br />Product (Condition <br />Value, Month Value) <br />Less Than <br />More Than <br />Sept <br />1.73 <br />3.35 <br />5.06 <br />1.05 <br />2.46 <br />3.77 <br />2.09 <br />3.93 <br />5.93 <br />2.43 <br />2.98 <br />4.56 <br />Wet <br />Normal <br />Normal <br />3 1 <br />2 2 <br />2 3 <br />3 <br />4 <br />6 <br />Oct <br />Nov <br />WETS Station: Everett Snohomish County AP, WA, Period <br />of Record 1990-2020 Total <br />13 <br />Observed Precipitation Station: Everett Snohomish County AP, WA, Year: 2020 <br />Form Adapted From NRCS Engineering Field Handbook, Chapter 19, Hydrology Tools for Wetland Determination <br />If Sum is: Then: *Condition Value: <br />*6-9 Prior Period Has Been Drier Than Normal Dry= 1 <br />od Has Normal = 2 <br />8 Prior Period Has Been Wetter Than Normal Wet = 3 <br />Figure 2 - Precipitation .-analysis for December 2020. <br />.Sage Homr.� .
