Sick of that vacant lot? Tired of that dead tree? Now you can clean them up using grant money from the Citizens Committee for New York City. The Love Your Block grant offers up to $1,000 for any community group looking to improve a street in a variety of ways (trash cleanup, bicycle parking — the sky’s the limit). The city also chips in by offering the help of the transportation, parks, and sanitation departments, as well as other agencies. Here’s the application. An informational session is today at 6:30 p.m. in Lower Manhattan.
