This coming Sunday afternoon, the Friends of Gulick Park will be marking “It’s My Park Day” with a basketball clinic, a playmobile being brought in by the city and lots of other fun activities. Most of all, though, they’ll be celebrating a major accomplishment — the approval of a plan to refurbish the neglected public space at Delancey and Willett streets. After four years of community visioning exercises and fundraising, Community Board 3 last month approved the plans to completely revamp Luther Gulick. Now it’s up to the Public Design Commission. You can see both the Phase 1 Plan and the final version here. The group has raised about half of the $6 million that will be required for the whole project.
