Improving resiliency preparedness for New York communities

The staggering impact of Hurricane Irene, Tropical Storm Lee and Superstorm Sandy was felt in large areas of New York, resulting in devastated communities and significant damage to infrastructure. As the frequency of such natural disasters continues to rise, fostering community resilience has become critically important.  

During Superstorm Sandy, the communities of Springfield Gardens, Brookville and Rosedale experienced extreme tidal flooding. The lack of permeable surfaces within the communities led to rainwater runoff, causing overflows of the stormwater system and flooding in areas beyond the range of the tidal flooding. The communities also experience frequent stormwater flooding on a smaller scale during high tide events, heavy rainstorms, and nor’easters due to their low-lying topography, high groundwater table, and proximity to tidal wetlands.

As part of the New York Rising Community Reconstruction Program established by the Governor’s Office of Storm Recovery, Louis Berger helped develop a plan that provides an integrated approach to resilience, including flood management in the Idlewild Watershed Communities. The plan includes several sustainable and cost-effective resilience strategies, which will serve to:

  • Alleviate localized flooding conditions.
  • Strengthen the emergency response capacity of the community.
  • Support environmental stewardship of the community’s natural and manmade resources.
  • Provide safe and reliable access to critical goods and services.

The plan also emphasizes the need for the expansion of green infrastructure for stormwater management, as well as implementation of concentrated education and training in order to increase local capacity for disaster recovery.
