1 Towards a Resilient Stormwater Future: Building Back from Hurricane Irene and Tropical Storm Lee October 15, 2015 VUSP Symposium Russ Dudley, P.E., LEED AP Environmental Engineer

2 Presentation Outline Impacts of Tropical Storm Lee and Hurricane Irene Government Response to Flood Disasters Green Infrastructure for Water Quantity and Quality Intersection of Hazard Mitigation, Green Infrastructure and Economic Development 2

3 Chesapeake Bay after TS Lee (2011) Upwards of 7 million tons of sediment was washed downstream to the Chesapeake Bay during the September storm event

4 Impact on Upstate NY Hurricane Irene 13 inches of rainfall in the Catskills on August 28 Tropical Storm Lee inches of rainfall near Binghamton on September 6-8 Credit: New York Times Credit: Perfect Storms by Steve Stanne 4

5 Flooding at Multiple Scales Regional riverine flooding Local stormwater flooding 5

6 Government Response to Flood Disasters 6

7 New York Rising Community Reconstruction Program Goal: Distribute HUD CDBG-DR funding for Hurricane Irene, Tropical Storm Lee, and Hurricane Sandy State created a new office Governor s Office of Storm Recovery to provide planning services, combined with bottom-up community participation Identified projects that replace or protect critical infrastructure, mitigate flood risk, and improve community resilience 7

9 Community Development Block Grant Disaster Recovery Projects need to be part of a rebuilding/recovery effort Not eligible if they focus on future disasters Projects must address a serious and immediate threat to community health/welfare CDBG-DR funds can be used as the non-federal match for USACE and FEMA projects Examples of Eligible Projects: Buyouts Relocation Debris removal Property rehabilitation Constructing or rehabilitating public facilities (i.e. streets, water and sewer systems) Planning and administration costs 9

10 CDBG-DR and Green Infrastructure From the Federal Register, as part of the CDBG-DR Funds in Response to Hurricane Sandy: To foster the rebuilding of more resilient neighborhoods and communities, HUD strongly encourages grantees to consider sustainable rebuilding scenarios such as the use of different development patterns, infill development and its reuse, alternative neighborhood designs, and the use of green infrastructure. 10
