IMPORTANT: BMA trailbuilding days are a little different in times of a pandemic, please note the following:

  • Volunteers must register with the City of Boulder’s Count Me In program and sign up for the event here. Once you complete the risk & COVID training and release form, you do not need to do it again for ANY projects. Just sign in and register for other trail events.
  • You must sign up online with BMA (below) so we can make sure we limit our group size to less than 25 people and have all waivers signed online.
  • You must wear a face covering and social distance while volunteering on OSMP property.
  • BMA will not be able to provide any group snacks or beverages, please bring your own.
  • BMA volunteers must adhere to Boulder County Public Health guidelines at all times and agree to the terms of our COVID-19 waiver below.
