Show Downtown You CARE!

Due to the coronavirus state of emergency, the April 25, 2020 clean up event was canceled. We hope to reschedule in spring 2021. Stay clean, safe and healthy! 

Saturday, September 26, 2020
8 a.m. - 11 a.m.

In lieu of the April 25 clean up event, the LDDA is partnering with the Gears Volunteer Community to plant 600 tulips/crocus in the Downtown area to bring more color in the spring! Thank you to Comcast for their support in 2020 despite the pandemic and event cancelation. 

The LDDA hopes to hold its annual Downtown Longmont Clean & Green in Spring 2021 in support of the city-wide Clean Up Green Up campaign which runs every April.

  • We make an impact with a variety of deep-cleaning and landscaping projects that go beyond the regular maintenance performed Downtown.
  • This year we will again partner with Comcast for their Comcast Cares Day employee volunteer event. 
  • A hearty breakfast, lunch and refreshments is provided for all volunteers.
  • Volunteers receive a Comcast Cares Day t-shirt and schwag bag filled with Downtown goodies, including a Own Downtown water bottle.

Volunteers that sign up for Clean & Green need to be able to handle physical activity including bending, lifting, twisting, and standing/walking for 3 hours. If you have any questions, please call Del Rae Heiser at 303-651-8586 or email

TO SIGN UP, please complete our online application.
