The city Department of Transportation is hoping to create a new set of permits that would allow landlords to install flood barrier systems on public streets and sidewalks outside their buildings.
The changes come as the result of flooding during Superstorm Sandy. Many structures, especially in lower Manhattan, were built all the way to the property line, meaning temporary flood walls, for example, would need to be erected on public streets or sidewalks—requiring a green light from the city.
A flood-protection system might consist of such things as permanent footings anchored to the sidewalk or building façade, to which temporary flood barriers could be fitted in the event of a storm threat.
The new proposed rules would also govern the timing of those temporary barriers. Landlords would be allowed to erect them two days before a storm, but would also require the walls' removal within a day after the water recedes.
