Shoreline, Washington, USA

The City of Shoreline is located within King County, Washington, in the Seattle metropolitan area along the Puget Sound (Figure 1). It is approximately 12 square miles or 7,416 acres, of which 7,389 are land acres. Shoreline has always placed a high priority on ensuring the long-term health of its urban forest resource, and this assessment demonstrates their continued commitment to protecting, maintaining, and expanding the city’s tree canopy.

This analysis is a follow-up to Shoreline’s first urban tree canopy assessment, which the City Council commissioned as a part of their City Sustainability Strategy nearly a decade ago. That study, completed by AMEC Earth & Environmental in March 2011, sought to establish a baseline of the city’s tree canopy that the City Council could, in turn, utilize to shape important policy decisions regarding Shoreline’s urban forest. The City Council also determined that the city’s urban tree canopy should be continually monitored at approximately 5-year intervals to assess its status and adjust policies as needed, thereby necessitating this subsequent assessment.
