Wetlands (SEPA Earth, Land, Piants and Water Policies) I. Site Descriation The .85 acres site is located northeast of the intersection of 100"' Street SE and 18'h Avenue West in the City of Evarett, Washin��ton. Most of the site has been cleared and is dominated by lawn with spora�iic Douglas f-ir trees within the southern portion. Along the eastern boundary, the site is dominat-.d by lawn area with sporadic red alder in the canopy. One jurisdictional wetland is partially located along the eastern property boundary. This is a relatively large wetland system associated with an off-site intermittent stream. The stream and wetland lay mostly off-site to the east, ar.d extend to the north and south for greater than 200 feet.
