Seaside’s Trusted General Contractor — Coastal-Ready Builds, Start-to-Finish

Seaside holds a distinction that most Oregon coast towns do not: it was there that the Lewis and Clark Expedition reached the Pacific Ocean in January 1806 and established a camp to boil seawater for salt — a replica saltworks stands at the site today, at the south end of the beach. The Clatsop people, whose village of Ne-co-tat occupied this coastal area for centuries, were the original inhabitants. Oregon's oldest ocean resort community, Seaside was developed in the early 1870s by railroad magnate Ben Holladay, who built the Seaside House hotel to attract wealthy Portlanders looking for a coastal getaway — the city's name derives from that hotel. The narrow-gauge Ilwaco Railway eventually connected the coast, and Seaside became the Pacific Northwest's premier ocean resort town through the late nineteenth and early twentieth centuries.

The city sits at the southern end of the Clatsop Plains, where the Necanicum River meets the Pacific Ocean at the city's northern edge, and Tillamook Head towers over the southern boundary. The two-mile oceanfront Promenade — the "Prom" — is the city's most distinctive feature: a concrete boardwalk along the beachfront that has been a gathering place since the 1920s.
