This document discusses the legal limits of mitigation and restoration requirements imposed by local governments. It defines mitigation as fixing problems created by a project, while restoration fixes problems created by others. The document examines several court cases that found conditions imposed on private property must have an essential nexus and be roughly proportional to the impacts. It also notes restoration goes beyond the standard of protection under growth management and shoreline laws. The document questions whether local governments can rely on regulatory powers to achieve large-scale restoration targets or if public investment is needed. It concludes restoration beyond mitigation can only be achieved through public funds and incentives, not regulatory requirements on private property.
