New zoning in Portland to address sea level rise

City planners are proposing new zoning rules for flood-prone areas of Portland in an effort to encourage developers to design buildings with sea level rise in mind.

The proposed Coastal Resiliency Overlay Zone would allow developers to build taller buildings in those areas if they prove the additional height is being used to prepare for sea level rise and storm surges associated with a changing climate.

“This overlay would incentivize property owners and developers who wish to build in parts of the city that face increasing threat from flooding to make their buildings resilient to flooding,” Sustainability Coordinator Troy Moon said in a memo to the Planning Board, which will review the proposal Tuesday.
