For North Denver’s Children’s Outreach Project, an early-childhood education program for low-income families, growing happy and healthy kids is more important than fending off weeds. That’s why, this month, the 45-year-old nonprofit will xeriscape its outdoor area—with the help of a few friends. Children’s Outreach Project is just one of 53 nonprofits that volunteers will help fix up during Amp the Cause’s 10th annual Community Day. On April 25, more than 1,000 locals will donate their time to paint, garden, mend, and generally improve nonprofit locations such as Bridge Project, Firefly Autism, Colorado Youth at Risk, and Re:Vision. After a full day’s work, buses will deliver the city’s hardest workers to Sculpture Park for an end-of-day celebration with food and, of course, beer. Founder Christie Isenberg created Community Day, which started with just 19 sites, as a way to involve the public in nonprofit work while saving the groups some cash. “The organizations then can spend their resources on the actual services they’re providing for the families and children they’re supporting,” Isenberg says. Last year, the total value of volunteer labor, donated supplies, and charitable contributions ticked past half a million dollars.
