Operation Green Sweep is a volunteer program for teens who want to earn community service

local parks, remove light rubbish and learn a thing or two about our parks and surrounding
environment.

Note: If you miss more than two days, you may be dropped from the program without earning
your hours. Please bring a snack, wear work clothes (no skirts or open-toed shoes) and sunscreen.
Teens are expected to arrive at the meeting place on time, learn communication skills and learn to plan ahead. All volunteers must meet at the Veteran’s Memorial Building to receive their tasks. Do not be late because transportation is provided to take teens to their selected sites.
