About this map

Semiahmoo Spit and the curved shoreline of Drayton Harbor define this coastal landscape at the northwestern edge of Washington. The community of Blaine occupies the interior, while the shoreline is dotted with residential developments and named points like Birch Point and Point Whitehorn. This 2023 survey illustrates the modern residential character of the region, where streets like Semiahmoo Pkwy and Birch Bay Dr follow the natural contours of the Salish Sea.

The map details the hydrological transition from the Strait of Georgia to inland features such as Unruh Reservoir and Terrell Creek. In the southern portion, Birch Bay and Cottonwood Beach represent established coastal settlements. The grid of the Public Land Survey System, including t40n r1w, provides a structural framework for a landscape that has shifted from early maritime industry toward a residential and recreational identity.
