; � .� _ . . . . . . . . . . . . � � � . . . C. .'. Cateqory IiI. Category III 'streams are those , . streams that are naturally intermittent or ephemeral . during years of normal rainfall and are not used by • salmonids in any portion of the stream system. • D. Cat�gory IV. Category' IV streams are naturally occurring, intermittent swales. , The City has established buffer and. setback requirements for the different categories to. regulate development around ' and/or alterations to streams and other sensitive areas. 9ITE 088ERVATIONB The stream observed was a small, unnamed tributary to Puget Sound which cuts across the northeastern-most corner of the property. The headwaters of the stream appear to be in the vicinity of City of Everett water storage tanks located to the south of 35th street and to the west of Tslalip Avenue. Although this upper area was not extensively examined, it appears that the creek .enters a ravine just west of the tanks before flowing onto the subject property. Accordinq to provided information, the underground water storage tanks are' leaking, resulting in year round flows to the stream. • ' � Onsite, the stream flows through a deep ravine near a bend in the old access road. A portion of the access road collapsed_ into the stream ,in the past, and is partially covering the streambed in places. The stream is characterized by aucky and silty substrate. The channel width varies in size from approximately one foot to four feet. Instream cover for. fisheries is .virtually nonexistent, and stream flow was not much more than a trickle. The streambanks onsite have been impacted by a large amount of lawn and garden waste that have been deposited into the ravine. No fish were observed, and no areas were found that appeared capable of supporting fish. Following onsite observations, the reach downstream of the . project site was' inspected. The stream continues in a - northwesterly direction to a bluff just southeast of the Burlington Northern Railroad tracks, which are southeast of a large log yard. Stream gradient_in this area appears to „ be at or greater than 25�_ The stream exits a shotgun culvert (estimated to be 24") and trickles through an undPfined channel area alang the south side of the railroad tracks. The stream is completely impassable to anadromous fish in this area. . The stream then flows through a culvert underneath the railroad tracks . into a ditch that parallels the north side of the :tracks: 2
