The full guide

A long, narrow ribbon of green runs down a hillside in Seattle's Mount Baker neighborhood until it reaches the shore of Lake Washington. This is Colman Park, a 24.3-acre city park stretching from 31st Avenue S to the water just south of the I-90 bridge. Its story begins with an early water pumping station, and in 2020 the park joined the National Register of Historic Places.

From the hilltop to the lakeshore

Picture the park as a slender strip of land. It drops from 31st Avenue S to the lakeshore, where Lake Washington Boulevard S runs along the water at its base. If you are setting your map, the official address is 1800 Lake Washington Blvd S, Seattle, WA 98144.

As you head along the boulevard, watch for the Lacey V. Murrow Memorial Bridge, which carries Interstate 90 across the lake. The park's northern edge sits just below it, so the bridge makes an easy landmark for finding your way.

The steam pump that saw Seattle through the Great Fire

Every walk here traces back, in a sense, to drinking water. In 1881 the Town Council approved Seattle's first municipal water company, which absorbed a tangle of private water systems and won the right to charge for service.

The Spring Hill Water Co. built a steam-powered pumping plant on Lake Washington in 1886, a long way from the town center in those days. When the main pump broke down, engineers brought in from the East could not work out the problem. Seattle engineer James M. Colman then took on the job and worked 36 hours without stopping until the pump ran again.

That same pump station worked hard during the Great Seattle Fire of 1889, and today the park carries Colman's name as a memorial to him.

Olmsted curves and a park built piece by piece

In 1907 the Park Board took control of the pumping plant site, along with part of the pipeline right-of-way climbing the hill. Frink Boulevard was then extended south on a route chosen by the Olmsted Brothers, curving down the slope to meet Lake Washington Boulevard as it came north along the shore.

From there, the park grew in stages:

  • Gifts of land and a purchase along the north side made the park wider.
  • In 1909 the State of Washington granted the shorelands for park purposes.
  • In 1910 the James M. Colman Estate filed a plat that deeded the head of the slope for park use and named the strip from 31st Avenue S to the lake in Colman's memory.

In 2020 Colman Park joined the National Register of Historic Places together with its next-door neighbor, Mount Baker Park.

The 2002 tree cutting case

The park made headlines in August 2002, when Joseph Jerome Farris, a senior judge on the Ninth Circuit Court of Appeals, had 120 mature bigleaf maple and native cherry trees in the park cut down to open up the Lake Washington view from his home. Some of those trees were more than 40 years old and stood taller than 55 feet.

The King County Prosecuting Attorney chose not to bring felony charges, but the Seattle City Attorney fined the judge $500,000, and when the fine went unpaid the city put a lien on his 8,000-square-foot Mount Baker house. The judge blamed a miscommunication with his gardener, who denied it. A jury later sided with the gardener in a lawsuit over insurance coverage, and the judge paid the full amount, $618,000 with interest, in May 2006.
