The Lincoln Reservoir was also covered on Capitol Hill, creating open green space in Cal Anderson Park.
As Highland Park community members have met on multiple occasions to discuss plans for the new Westcrest reservoir lid, it has become clear that not everyone agrees on what would be the best use for the new space.
Dan Mullins, president of the Highland Park Action Committee, has collected hundreds of suggestions for use of the lid.
Community members have suggested creating a viewpoint, which would overlook Downtown Seattle, or an open space for picnics.
Many neighbors have also asked for a walking or running path in the park.
While some community members want to activate the space with a sports play field, other neighbors have adamantly opposed that idea, which they say limits the use of the space.
Other have requested an outdoor amphitheater where summer concerts could be held.
One very popular request from the community has asked that a P-Patch be created on the reservoir lid.
"This neighborhood really needs a P-Patch," said Mullins. "There are lots of people living in apartments or townhomes who could use a place to grow (their own food.)"
Overall, use of the reservoir lid will likely depend on what Seattle's Parks and Recreation Department says the area can sustain. Because there is limited soil on the lid, these areas tend to be very sensitive.
Part of Cal Anderson Park, on Capitol Hill, covers the Lincoln Reservoir, though the new green space created is primarily just open for picnics and other social activities, rather than planting or sports.
