What to do when the historic district floods.

I just finished reading a new article by Jess Phelps in the latest issue of Environmental Law. In Preserving Perpetuity?: Exploring the Challenges of Perpetual Preservation in an Ever-Changing World, Phelps tackles some issues closely related to questions I research: what do we do about perpetual permanent restrictions in a world of constant change? Phelps takes a narrower tack  than my articles though, looking just at historic preservation easements. If you think that perpetual land conservation sound challenging, try fooling yourself into thinking that buildings are going to last forever. Well, okay we all know that perpetual restrictions have their usefulness even when we know that a perpetual building is not possible. What I like about Phelps' piece is that he cites me he takes a practical approach, providing specific plans for how to respond when natural disasters damage or destroy structures protected by historic preservation easements. It is a helpful read for land trusts or drafters of conservation easements thinking proactively about climate change impacts.
