Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.
The Willamette River divides Portland into distinct east and west neighborhoods with different character; crossing it can affect perceived distance and commute time even over modest straight-line miles. Gresham (~12 miles east) is a good example of an eastside suburb that sits close on the map.
The West Hills form a forested ridge on the city's west side. Beaverton (~6 miles west) and Hillsboro (~15 miles west) are relatively close in straight-line distance, but driving routes navigate around the hills, so travel can feel longer than the radius suggests.
Milwaukie (~5 miles south) sits well within the inner ring, while Salem (~43 miles southwest) remains a separate city despite sharing the valley. Cascade Locks (~40 miles east) marks the eastward route toward the mountains.
A 10-mile radius from downtown Portland, near City Hall covers roughly 314 square miles and includes Portland's core neighborhoods along with Milwaukie (~5 miles south), Beaverton (~6 miles west), Lake Oswego (~7 miles south), Tigard (~7 miles southwest), and Tualatin (~10 miles southwest). Gresham (~12 miles east) and Oregon City (~11 miles south) lie just beyond this radius.
The 5-mile radius reaches Portland's downtown core and the inner eastside and westside neighborhoods, plus Milwaukie (~5 miles south). Most other suburbs lie beyond 5 miles — Beaverton (~6 miles west), Lake Oswego (~7 miles south), and Tigard (~7 miles southwest) all fall just outside this inner circle.
Yes. Beaverton is about 6 miles west of downtown Portland by straight-line distance, placing it well within the 10-mile radius. The West Hills sit between the two, so driving routes navigate around forested terrain and travel times can run longer than the straight-line distance suggests.
East-side suburbs such as Gresham (~12 miles east), Fairview (~12 miles east), and Troutdale (~14 miles east) extend across the valley floor. West-side suburbs including Beaverton (~6 miles west), Tigard (~7 miles southwest), Lake Oswego (~7 miles south), and Hillsboro (~15 miles west) sit behind the West Hills. Notably, Beaverton (~6 miles west) is closer than Gresham (~12 miles east), though the hills can make the west side feel farther.
Gresham is approximately 12 miles east of downtown Portland by straight-line distance, making it one of the largest suburbs in that direction and placing it just beyond the 10-mile radius but inside the 15-mile ring.
Salem, Oregon's capital, is about 43 miles southwest; Cascade Locks is about 40 miles east toward the mountains. Both fall within the 50-mile ring. The Dalles (~73 miles east) and Newport (~90 miles southwest) lie beyond this regional radius.
