Rebuilding a more resilient South Valley Stream Community in New York

Beginning in August 2011, the State of New York suffered three severe weather incidents in the span of a year. Hurricane Irene, Tropical Storm Lee and Superstorm Sandy wreaked havoc on the State, and these extreme weather events have heralded the immediate need to rebuild more resilient communities.

Challenge
South Valley Stream in Nassau County, New York, is vulnerable to flooding from tidal and precipitation storm events due to several creeks extending into the community. During Superstorm Sandy, the storm surge caused flooding that was further intensified by the accumulation of stormwater. As a result, more than 1,000 residential and commercial properties were damaged. South Valley Stream remained susceptible to flooding events due to an increase in stormwater runoff, inadequate drainage system capacity and the potential for increased coastal flooding. 

Solution
As part of the New York Rising Community Reconstruction Program established by the Governor’s Office of Storm Recovery (GOSR), Louis Berger helped develop a plan that provides an integrated approach to resilience including flood management in the South Valley Stream community. This plan includes several sustainable and cost-effective resilience strategies to:

  • Manage tidal flow and retain stormwater.
  • Improve natural habitat and living shorelines.
  • Reinforce the power grid, including microgrids.
  • Strengthen communication and coordination.
  • Maintain and enhance economic viability.

The resiliency plan was recognized and awarded “Best Use of Green Infrastructure” by GOSR for using green resiliency strategies to improve coastal protection, including a terraced pathway, erosion and sediment control elements, permeable pavements, living shoreline bioswales and educational signage in conjunction with new and enhanced community open spaces and waterfront access, new and improved neighborhood pedestrian connections and improved terrestrial and aquatic habitats.
