Commercial Activity

A Park Permit may be obtained from Jeffco Open Space to authorize companies or individuals to conduct business within Jeffco Open Space managed lands. A Park Permit provides a group with a non-exclusive license to offer services to park visitors.

An organization is considered a business if it provides goods, services, or activities to the public using Jeffco Open Space managed lands. If an individual receives any form of compensation for what they are providing they are considered to be conducting a business or commercial activity.

Permitted activities must be appropriate to the mission of Jeffco Open Space; complement resource protection, visitor protection and interpretation goals; and not pose any potential for derogation of values or purposes for which Jeffco Open Space was established.

Currently, the following commercial activities may be permitted by Jeffco Open Space:

School Groups

All school groups regardless of group size or activity must have a valid Park Permit, including all athletic teams, clubs, field trips, or other organized activities. School groups of more than 60 total people will not be permitted and issuance of a permit is based on time, location, and capacity limits of each park. 

A valid certificate of insurance which lists Jefferson County Open Space as a certificate holder is required for all school groups.  

New for 2019; Due to the rapid increase in park visitation and requests for group activities, applicants requesting annual permits are now required to submit a schedule of events, which should indicate requested parks, dates, times, and maximum number of participants.

Special Activity

The application for 2020 Special Activities is now live. Applications for Special Activities are accepted and reviewed once per year and the application for 2020 events will close on October 8th, 2019 at 11:59pm. Applications will be reviewed and applicants notified no later than December 1st, 2019.  

Please apply using this link.

Events such as tours, races, rides, walks, festivals, fun runs, etc. require a special activity permit and will fall into one of two categories:

Category 1 - Events that exceed 200 people and/or require exclusive use of JCOS managed trails or park. A maximum of five total Category 1 special events may be permitted per calendar year and are limited to a maximum of one event per visitor group: hiking/running, equestrian, mountain biking, the arts, etc. Category 1 events must be administered by a public or non-profit organization to benefit a charitable cause and the organization must be the applicant for the permit. 

Category 2
- Events that are less than 200 people and do not require exclusive use of a park, trail or other area.

All events will be considered on a case-by-case basis and those that align with or support the mission of JCOS will be given preference. Further, in recent years JCOS parks have seen a significant increase in visitation with estimated annual visits totaling approximately 6.9 million. This volume of visitation places a challenge on trails, facilities, parking areas, and the experience of other visitors. Applications that take this into consideration and demonstrate measures to minimize impacts on trails, park facilities, parking areas, and park visitors will be given preference. Events that take place during peak times, primarily weekends and evenings, should plan to stage all non-trail related activities off-site and explain this plan in their application.

Restricted Dates:

Events that fall on holidays or holiday weekends will not be considered. In addition, JCOS may limit the number and timing of events in certain locations to reduce the impact and inconvenience for park visitors, neighbors and park and natural resources. Currently, the following dates will not be considered for Special Activities in 2020 (please note that this list is subject to change):

January 1 

January 20 and January 21

All approved applications are subject to a cost recovery fee, typically $5.00 per participant. Exceptions and reductions may be made on a case-by-case basis for governmental and non-profit organizations that directly benefit the people of Jefferson County. Justification for an exception or reduction should be reflected in your application. Additionally, all events require a damage deposit which is due no later than thirty days prior to the event. Damage deposits are typically $200.00 and refundable, but may be higher depending on scope of event.
