Seaside is a city in Clatsop County, Oregon, United States, on the coast of the Pacific Ocean.

[6] The Clatsop were a historic Native American tribe that had a village named Ne-co-tat (in their Chinook language) in this area.

About January 1, 1806, a group of men from the Lewis and Clark Expedition built a salt-making cairn at the site later developed as Seaside.

After living in San Francisco, California and Astoria, Oregon, Gilbert moved to Seaside where he had a beach cottage (built in 1885).

Gilbert was a real estate developer who donated land to the City of Seaside for its one-and-a-half-mile-long Promenade, or "Prom," along the Pacific beach.

Gilbert died at home in Seaside and is interred in Ocean View Abbey Mausoleum in Warrenton.

The geography associated with the gradual slope of the broad sandy beaches of Clatsop Spit provide excellent conditions for the formation of beds of millions of Pacific razor clams annually.

[10] Waves attract surfers all year round from the challenging point break off the tip of Tillamook Head to the sandy shores at "the cove" parking lot at Ocean Vista Drive.

Among other preparation, the City of Seaside has embarked on a program in which residents above the zone are asked to volunteer to store within their homes barrels of medical supplies, water purification systems, emergency rations, tarps, and radios, with each barrel having enough supplies to last 20 individuals for at least 3 days.

[18] On Tues. Nov. 8, 2016, Seaside citizens voted 65% to 35% to issue $99.7 million in bonds to move the remaining three schools out of the tsunami inundation zone.

Seaside hosts an annual 4th of July celebration which includes a parade, outdoor concerts, and one of the largest fireworks displays on the west coast.

Five men of the Lewis and Clark expedition needed nearly two months to make the equivalent of 28 US gallons (110 L) of salt; it was critical for them to be able to preserve meat for the winter and their several thousand-mile journey home to the East.
