You may have already known that Seattle is consistently ranked as having one of the best park systems in the US — but did you know that's quite literally by design?

There have been plenty of factors that have ultimately led to our robust catalog of green spaces, but one big cause can be traced back to 1903 when Seattle hired John Charles Olmsted to design a network of parks.

Olmsted was, at the time, the co-owner of the Olmsted Brothers landscaping design firm, which had been responsible for New York City's Central Park and Boston's "Emerald Necklace."

And while a lot of Eastern cities are pretty proud to have one or two of these works, Seattle has 37 of their parks and playgrounds. Uh, no big deal or anything.

How did we end up with so many?

In the wake of the Klondike Gold Rush, Seattle was quickly expanding and the city saw an opportunity to begin protecting and preserving its land before too much was lost to development. In 1902, an official movement began in the Seattle Board of Park Commissioners to build a more elaborate system and hired the Olmsted firm.

Olmsted and his assistant traveled to Seattle to begin taking stock of the land and its most beautiful areas. The two then took their findings and overlaid them with two previously completed (but not enacted) designs — a parks plan created in 1892 and a proposed 25-mile system of bike paths — to create their Comprehensive System of Parks and Parkways.

In 1903, city council approved the proposal and the Olmsted firm got to work. Cal Anderson Park became the first Olmsted designed park in 1904. The firm's relationship with the city lasted until 1941.
