It's been a year since Denver first installed 36 red refurbished parking meters downtown to raise awareness -- and money -- for its 10-year plan to end homelessness. Today, 86 downtown meters are collecting change for initiatives that provide meals, job training, substance-abuse counseling, housing and other programs. Overseen by the city's Department of Public Works, the Donation Meter Program also adopts meters out at $1,000 per meter per year, which is generating about $100,000 in revenue annually for Denver's Road Home program. In the first six months, the meters collected nearly $8,500. While they may not be a significant revenue source, the meters have helped redirect money once given to panhandlers to homeless initiatives. The idea -- first tried in Baltimore, where 10 blue-and-green meters can be found around the Inner Harbor -- is spreading: Cities that have either rolled out or are considering donation meters in their downtowns include Colorado Springs, Las Vegas and Chattanooga.
