The Model Permission for Encroachment is a license agreement that allows an encroachment to continue until the owner withdraws permission. The model document also features owner protections from claims pertaining to injury or property damage, a requirement that the encroacher comply with the law, and the termination of any rights the encroacher may have to claim adverse possession.
The risk of being held responsible for injuries or property damage associated with organizing volunteer, educational, recreational and other events and activities (or opening up property for the same) can be minimized by having those who wish to participate sign a release agreement. The Model Release Agreement provides nonprofits with a well-designed template and example to work from. The guide Release Agreements provides commentary for the model.
Land trusts can use this tool to estimate the annual costs of stewardship for a conservation easement and the initial investment in a stewardship fund that will be needed to cover the costs. The calculator can be adapted to the needs of an individual land trust and to the specifics of a conservation easement. The guide "Costs of Conservation Easement Stewardship" (http://conservationtools.org/guides/86) explains many of the features and choices made in the calculator.
