Wetland Delineation Report June, 2015 South Everett Forest Preserve ©2015 Perteet Inc. Chapter I. Proposed Project 1.1 Introduction The City of Everett Parks and Recreation Department (Everett Parks) proposes to create pedestrian trails on an undeveloped lot as replacement for the conversion of Thornton A. Sullivan Park to a municipal fire station. The creation of passive recreation facilities at this undeveloped lot (South Everett Forest Preserve) will compensate for those uses previously provided at Sullivan Park (conversion site). This mitigation is required because Sullivan Park has grant-protected status and is protected by Section 6(f)(3) of the Land and Water Conservation Fund Act (LWCF). This federal grant stipulates that conversion of parkland to non-recreation uses requires adequate replacement of the displaced area and uses, and preparation of an Environmental Assessment pursuant to the National Environmental Policy Act (NEPA). The National Park Service is the federal agency responsible for compliance with the LWCF Act and NEPA reporting requirements. Past environmental studies have been conducted at both the South Everett Forest Preserve and Sullivan Park site (Watershed Company 2012 and Jay Group 2007). This includes previous wetland delineations at the South Everett Forest Preserve in 2003 and 2007. These delineations identified a Category I wetland and unnamed tributary of North Creek on the South Everett Forest Preserve that extends off- site to the north. Because the previous delineation in 2007 is more than five years old, the wetland boundary on the South Everett Forest Preserve was re-delineated by Perteet biologists, as described in this report. 1.2 Project Location The South Everett Forest Preserve is located northwest of Silver Lake in Everett, Snohomish County, Washington (Figure 1). This 3.57-acre property is located between I-5 to the east and 77th Avenue SE to the west. The project site is an undeveloped lot owned by the City of Everett. The Snohomish County parcel identification number is 28051900400900. The Public Land Survey System location of the project area is Section 19, Township 28N, Range 05E, W.M. 1.3 Landscape Setting The South Everett Forest Preserve lies within the greater Lake Washington drainage basin and specifically within the North Creek subbasin. Elevations within the immediate project area are relatively flat and are approximately 477 feet above sea level. A tributary of North Creek (Silver Lake Creek) flows from north to south through the South Everett Forest Preserve property from a large off-site wetland complex (Watershed Company 2012 and Jay Group 2007). Silver Lake Creek exits the South Everett Forest Preserve property via a culvert beneath a driveway to the Snohomish County District 1 Public Utility Facility. The project area contains a mixture of single-family residential neighborhoods and transportation corridors. The western edge of the site is bordered by residential areas, while the eastern edge is bordered by the Interurban Trail and Interstate 5 (1-5). The southern edge abuts an electrical substation operated by Snohomish County District I Public Utility and the northern edge consists of an undeveloped forested lot. The South Everett Forest Preserve is a rectangular shaped 3.57 acre parcel with hummocky ground that slopes gradually to the east. There are numerous informal trails crisscrossing the site that are used by the adjacent neighbors. The South Everett Forest Preserve is zoned Public Park Zone (P). Page 4
