Heritage Conservancy has prepared information on the economic benefits of the community's purchase of open space or conservation easements. In terms of school district costs,new residential development has a net cost to the community. The community's purchase of conservation easements pays for intself in a few years when compared to the on-going shortfall to the school system from residential development. Although nonresidential development produces revenues for the school system, there are other costs to the community, particularly in road improvments. We are interested in information that supports or does not support these findings. Results of our study is available.
