SALT LAKE CITY — The city’s Sustainability Department and the mayor’s office has launched an online survey to solicit resident feedback on its Neighborhood Cleanup program.

The survey, at slcgreen.com/ncu, will be open through Friday, Sept. 8. It is available in English and Spanish.

The Neighborhood Cleanup program, which is more than 20 years old, allows residents of single-family homes, duplexes and triplexes to dispose of large materials on their curb. Residents are notified of their collection period three weeks in advance via a postcard in the mail.

More than 5,000 tons of material is collected annually, with 22 percent being recycled or composted. The program runs from April to September each year, and residents pay for the service through their monthly garbage fee on their water bill.

“There have been many small changes to the program over the years,” Mayor Jackie Biskupski said in a statement. “However, there has never been a significant update to the program to address residents' needs and the environmental impacts. We’re asking the public to let us know what’s working, what’s not and how we can make improvements.”

The survey asks residents to consider several changes to the program to better protect environmental quality, provide greater convenience, minimize illegal dumping and increase the amount of material that is recycled.

The Sustainability Department will collect feedback online and at community events over several weeks.
