Strickland, Friends:The New York City Department of Environmental Protection (DEP) is proactively planning for climate change, from reducing greenhouse gas emissions to preparing for the impacts of extreme weather to drinking water and WasteWater infrastructure. When Hurricane Sandy hit in October 2012, DEP was already in the process of studying the potential impacts of storm surge and sea level rise, to consider measures to protect the low-lying WasteWater treatment plants and pumping stations that help drain our streets and keep our water-ways and beaches clean for the enjoyment of millions of New Yorkers.

2 After Sandy s surge caused damage to WasteWater facilities, resulting in millions of gallons of untreated and partially treated WasteWater spilling into the harbor, DEP quickly reacted to repair damage and to develop resilieNCY measures such as elevat-ing and flood-proofing equipment to ensure the highest levels of protection from future storms. The NYC WasteWater resilieNCY plan presents a comprehensive assessment of facilities at-risk from future storms, potential costs, and suggested measures to protect critical equipment and reduce the risk of dam-age and loss of services. The report follows the recent release of Mayor Bloomberg s A Stronger, More Re-silient New York, which committed the City to harden its WasteWater treatment plants and pumping stations. With 14 WasteWater treatment plants and 96 pumping stations, prioritizing the most at-risk facilities included an extensive and in-depth assessment of the height of critical assets in relation to projected flood heights.

3 In determining the benefits of resilieNCY measures and the level of acceptable costs, DEP considered not only the value of WasteWater assets, but also the population and critical facilities in the service areas and potential impacts on beaches. resilieNCY measures were then selected based upon costs and level of risk reduction. The result is a portfolio of strategies that will be shovel ready for funding opportunities and implementation as part of planned capital projects. Investing in our WasteWater infrastructure today will ensure the continuity of critical services well into the future. By implementing these strategies along with initiatives to improve energy reliability, build green infra-structure, improve and expand drainage infrastructure, and promote redundancy and flexibility of our water supply, DEP will continue to be a leader in proactive planning for climate change, to ensure the resilieNCY of New York City s water resources.
