ASPECT CONSULTING PROJECT NO. AS190583A-08  MAY 21, 2025 FINAL 11 (NAVD88) (20 feet above mean lower low water [MLLW]2) along the eastern boundary to approximately 15 feet NAVD88 (17 feet MLLW) on the western boundary, with a few feet of variation across the area. Following completion of the third IA, the site within the Port’s property will be paved and graded to direct stormwater to the new stormwater filtration systems. 2.4.2 Climate The climate of the Everett area is maritime, characterized by cool summers and mild winters influenced by ocean air. The average annual minimum temperature is 42.6 degrees Fahrenheit, and the average maximum temperature is 59.1 degrees Fahrenheit (Western Regional Climate Center, 2012). The average annual precipitation in Everett is 36.7 inches, with greater than 4 inches of precipitation per month from November through January. 2.4.3 Ecological Setting The information regarding the Upland Area’s ecological setting presented in this section was obtained from the Habitat Assessment for the Kimberly-Clark Everett Mill Site Demolition Project, which was prepared prior to mill demolition (Anchor QEA, 2012). The western boundary of the Upland Area is adjacent to the marine environment of the East Waterway in Port Gardner Bay of Possession Sound, which is mapped by the U.S. Fish and Wildlife Service as E1UB (Estuarine Subtidal Unconsolidated Bottom) habitat. The Upland Area shoreline is a bulkhead comprised mostly of riprap, chunks of concrete, and large rock material, with some wood bulkhead located on the north end. Wetlands, streams, or drainage channels are not present within the Upland Area. Upland vegetation is limited to a narrow strip of grass, trees, and shrubs associated with a former walking trail inland of the bulkhead shoreline. Plant species include western red cedar and the nonnative species Himalayan blackberry and butterfly bush. Wildlife species on the Site include bird species common in urban areas of Snohomish County: crows, house sparrows, black-capped chickadees, terns, gull species, and a nesting pair of ospreys. No amphibian, reptile, or mammal species, tracks, or signs were observed in a Site reconnaissance by Anchor QEA. Terrestrial wildlife species including rabbits, nutria, and coyotes are occasionally observed on the Site. The adjacent East Waterway offshore of the Upland Area is identified as Dungeness crab priority habitat. Areas in Port Gardner Bay are also identified by the City of Everett and the Washington Department of Fish and Wildlife (WDFW) as haul-out areas for California sea lions and harbor seals, regular large concentrations of waterfowl (e.g., ducks, herons, gulls, and terns), and intertidal hard-shell clam areas. Harbor seals are also commonly observed on log booms located near the shoreline of the Upland Area. No Endangered Species Act-listed animal species are known to occur within the Upland Area. The five Endangered Species Act-listed terrestrial species within Snohomish County 2 In Everett, the MLLW datum is 2.3 feet lower than the NAVD88 datum, i.e., elevations relative to MLLW are 2.3 feet higher than relative to NAVD88.
