Seattle Parks is set to remove an illicit skate bowl from the middle of Green Lake.

Crews will likely begin demolishing the concrete ramp on Duck Island on Tuesday morning.

It will take about three days to dismantle the ramp. Crews will break the ramp into pieces, remove them from the island, and take them to the dump.

There will also be a longer restoration effort taking place as crews finish with seasonal planting.

Seattle Parks had initially planned to demolish the park last week.

The ramp popped up about a month ago when a group of amateur skateboarders built it as part of a contest encouraging skateboarders to build their own skate parks. The skateboarders filmed the construction for the contest.

However, the ramp was not authorized, according to Seattle Parks. It also got pushback from environmental groups who want to preserve the island as a bird habitat.
