Maine Governor Janet Mills signed into law LD 563, “An Act to Help Municipalities Prepare for Sea Level Rise” in May 2019. The law amends the State’s growth management and local land-use planning requirements (at Title 30-A, Chapter 187 of the Maine Code) to address the effects of sea-level rise. It allows coastal municipalities and “multimunicipal” regions including coastal municipalities to consider sea level rise projections and potential effects on buildings, transportation infrastructure, sewage treatment facilities, and other municipal or private facilities.
