Legislation at a Glance
5: Remove Barriers to Sidewalk Flood Protection
Local Law 109 of 2013
Building owners may wish to install flood barriers on sidewalks, but are deterred by codes that limit sidewalk use and that assume buildings are fully occupied during floods. This legislation allows temporary flood barriers or shields, and their supports and attachments, to extend into the public right-of-way. It also allows temporary stairs and ramps to be used to access exits above the flood line.

In flood zones, footings for temporary flood barriers or shields may extend up to 12 inches beyond the street line, both at and below grade.
