Green roofs are still able to perform in cold weather, although not necessarily at the same level of effectiveness as during warm seasons. The soil in green roofs is porous and remains pervious when frozen. Consequently, rainfall as well as snow that melts during freeze-thaw cycles can still be stored, although the water will not be used by dormant plants.
The Developers Green Infrastructure Guide 2.0 breaks down New Jersey’s Stormwater Rule amendments and helps developers and decision-makers understand more clearly green infrastructure options and advantages, compare alternatives, evaluate costs and benefits.
The Developers Green Infrastructure Guide 2.0 is brought to you by the Developers Green Infrastructure Task Force, a partnership between New Jersey Future and the New Jersey Builders Association.
The Task Force gratefully acknowledges the financial support of the William Penn Foundation, which made this project possible.
