In the 2008 Parks and Green Spaces Levy, Uptown was designated as a priority area for new community garden development. Vacant land in this dense, urban neighborhood was difficult to come by. Luckily, a creative solution was worked out with the Department of Neighborhoods and Seattle Center. The Seattle Center has offered the community nearly half of the top level of the Mercer Garage as an experimentation site for rooftop gardening. Visible from both the top of Queen Anne Hill and the Space Needle, the garden will be a highlighted attraction during the Seattle Center's Next 50 Anniversary celebrations through 2012. The P-Patch will remain as a public gardening space for the next couple years until the Mercer Garage is redeveloped as part of the Seattle Center Master Plan. At the point the community intends to find a more permanent location in the surrounding neighborhood.
