and areas of McKenna soils, Norma soils and Terric Medisaprists in drainageways on plains. Also <br />included are small areas of Everett, Indianola and Ragnar soils on terraces and outwash plains. <br />� Permeabifity of this Alderwood soil is moderately rapid above the hardpan and very slow through it. <br />Available water capacity is low. Effective rooting depth is 20 to 40 inches. Runoff is slow, and the <br />hazard af water erosion is slight. A seasonal perched water table is at a depth of 18 to 36 inches <br />from January to March. <br />Everett aravellv sandv loam <br />Everett gra��elly sandy loam is a very deep and somewhat excessively drained soil on terraces and <br />outwash plains. It formed in glacial outwash. Typically the surface layer, where mixed to a depth of <br />about 6 inches, is daric brown (7.5YR 3/2) gravelly sandy loam. The subsoils are dark brown (7.5YR <br />3/2 to 4/2) very gravelly sandy loam about 12 inches thidc. The upper part of the substratum is brown <br />(7.5YR 5/2) very gravelly loamy sand about 5 inches [hick. Permeability of this Everett soil is rapid. <br />Available water capacity is low. Effective rooting depth is at 60 inches or more. Runoff is slow, and <br />the hazard of water erosion is slight. Included in this unit are small areas of Alderwood soils on till <br />plai�ys, Indianola soils on terraces and outwash plains, and Ragnar soils on outwash plains. <br />Mukilteo muck <br />MukiReo muck is very deep very poorly drained soil in depressional areas. It formed in organic <br />material derived dominantly from sedges. Typically, the upper layer is dark reddish brown (5YR 2/2) <br />muck about 4 inches thick. The next layer is dark reddish brown and black (5YR 2/2 to 3/2 and 10YR <br />2'0) organic material 4 to 35 inches thick. Pertneability of this Mukilteo soil is moderate. Available <br />water capacity is high. Effective rooting depth is Iimited by a high water table that is at or near the <br />surface from October to May. Runoff is ponded. In most areas of this unit, the water table is <br />art�cially drained to a depth of about 3 to 4 feet during the growing season. Some areas are ponded <br />during the rainy season. Included in this unit are areas of Terric Medisaprists, Orcas peat, and <br />Mukilteo soils that have noi been artficially drained. <br />During the site invesiigation in July 2006, numerous test pits were dug to detertnine the presence or <br />lack of hydric soils and wetfands. The majority of the test pits match the description of Alderwood <br />gravelly loam, with the exception of those areas identified as wetland. <br />9 <br />(Z <br />
