CA AB2939

Requires cities, counties, and city-counties to treat use of local parks by eligible entities to provide interpretive services to 30 or fewer visitors as an allowable public use, treated the same as general public use.

Defines eligible entities as qualified nonprofit public benefit corporations focused on outdoor equity, federally recognized Native American tribes, or California tribes on the Native American Heritage Commission's consultation list.

Defines interpretive services as activities and programs helping park visitors understand and connect with natural, cultural, and historic resources not generally offered by the local entity.

Allows local entities to adopt requirements for eligible entities if supported by substantial evidence showing necessity to protect public access, environmental resources, further park access, or address liability concerns.

Applies to all cities including charter cities, and provides for state reimbursement of any costs mandated by the Commission on State Mandates under Government Code Part 7.
