About

The Boulder Model Airport has been located on the northwest quadrant of Parks and Recreation property surrounding the Boulder Reservoir since at least 1980. This unique facility allows for the operation and enjoyment of model aircraft by the general public ("small unmanned aircraft" as defined by Federal Aviation Administration regulations).

The property is owned by the City of Boulder Parks and Recreation Department, while Boulder Aeromodeling Society has a license for the operation of the airport facility.

Seasonal Wildlife Restrictions

Current Status: Flight Restrictions in place until Sept. 10. See map under "related resources."

Each year, flight restrictions go into place to protect several nesting bird species of conservation concern. These species include: Burrowing owl, American bittern, Osprey and Northern harrier. The area around the Boulder Model Airport provides important nesting habitat for these species. It is critical to balance the needs of the species with the use and enjoyment of the Model Airport.

Northern Harriers, American Bitterns and Burrowing Owls are ground nesters which make them particularly vulnerable to disturbance by foot traffic. During the seasonal restrictions, downed aircraft are only to be retrieved by trained members of City of Boulder staff or Boulder Aeromodeling Society. If you need assistance retrieving a downed aircraft, please contact Boulder Aeromodeling Society for a list of trained members or call 303-413-7200 and follow the prompts to leave a voicemail for the Natural Lands team.
