Lessons for the shore: Bolstering resilience of the built environment

Nearly 32 million people, or 28% of the East Coast's population, live in areas lying within a mile of a shore line. The good news is that municipalities are starting to take action, writes Sasaki Associates.

Nearly 32 million people, or 28% of the East Coast's population, live in areas lying within a mile of a shore line. These are huge swaths of land inhabited by large populations—and these communities are at distinct risk of devastation given the trajectory of rising sea levels and the growing frequency and strength of major storms.

Coastal communities along the eastern seaboard were not always in such danger. Early settlers built their towns along protected waterways rather than directly on ocean shores to insulate themselves from threats. While this initial planning proved sound, over time cities filled in land to continue expanding, making some of the East Coast's largest cities the most at-risk, including Boston, New Haven, Washington DC, and New York City.

The good news is that these municipalities are paying attention. Better yet, the federal government is invested in finding a safe path forward for regions at risk nationwide. Obama's administration earmarked $1B toward an innovation and design competition inviting communities recently affected by natural disasters to compete for funds to both rebuild and bolster resilience in anticipation of future incidents.

Borrowing from the successful model of HUD's Rebuild by Design competition, the goal of the National Disaster Resilience Competition is to "get resources to communities to help them develop innovative, data-driven, and community-led approaches to recover from their disasters and increase resilience to future threats." HUD hopes for widespread participation from regions across the U.S and will post the Notice of Funding Availability in the coming weeks to officially solicit proposals.

In light of the new funds available it is the prime opportunity to think hard about the kinds of interventions shorefront communities can make to rebuild with an eye toward the future. It requires an acceptance of the new threats these communities face and a willingness to think about coastal resilience differently. Sasaki has developed several innovative solutions with input from the public and civic leaders in the wake of Hurricane Sandy and can help similar coastal communities begin to think about what a path forward could look like:

• Massapequa, N.Y. Following Hurricane Sandy, Massapequa and Massapequa Park, faced flooding, unlit streets, and infrastructure failure. It was clear that to rebuild Massapequa needed to construct a lifeline road network with key segments elevated to prevent flooding. Green infrastructure systems were also integral to several proposed projects to make Massapequa more resilient; these systems range from restored shorelines to flood valves to storm-absorbing park design.

• Natco Lake district, N.J. The Natco Lake district is a complex shoreline region encompassing Union Beach, Keansurg, and a manmade lake between them. This rich estuarine environment supports densely-populated maritime communities, a variety of industrial uses, and a local economy increasingly tied to New York City. In rebuilding the objective was to reduce flooding from storm events, protect communities from storm surge risks, and reconnect residents and visitors to a regional recreation amenity that provides better drainage into watersheds and wetlands.

Achieving this objective would require developing marsh landscapes to mitigate contamination and support fishing in the area; cleaning creek watershed through dredging; removing non-native vegetation to accommodate more wetland surface area to absorb flood water from neighboring towns; and linking the community to these recreational sites with trails so that the Natco Lake district transforms into a community destination.

Bridgeport, Conn. Parks will become the green infrastructure of Bridgeport, supporting the ecological, social, and economic health of the city. The linear waterfronts are an important part of the park system as a network of public access along all creeks within Bridgeport's boundaries. The parks and waterfront will play an important role in improving the ecological health and diversity in this city. Over the next decades, Bridgeport's restoration of the shoreline will prevent erosion, protect key habitat areas, absorb stormwater, and brace for storm surges.

If you live on the East Coast there is a 1 in 3 chance that you live within a mile of the shoreline. In fact, 51% of the total length of the East Coast, over 2,000 miles, exist in similar conditions to those described in Massapequa, Natco Lake district, and Bridgeport. The funds, the support, the expertise, the community engagement, the framework, and the sheer momentum, are all there to support municipalities on the east coast and across the country to rebuild for the future.

And these particular examples, culled from the NY Rising competition, provide good models for how to engage in a top-town and bottom-up approach to incorporate both the needs of the community and industry expertise to find resiliency solutions that can actually leave the drawing board and get implemented. It is absolutely the right time to make meaningful investments in the areas facing the greatest risk.

As former Mayor Bloomberg so eloquently expressed, "let me be clear: We are not going to abandon the waterfront. We are not going to leave the Rockaways or Coney Island or Staten Island's South Shore. But we can't just rebuild what was there and hope for the best. We have to build smarter and stronger and more sustainably." That is the charge, not just for New York but for all the regions lining the Atlantic coast that remain vulnerable to natural threats today and are ready to solve for ways to take those threats head-on.

Read on about innovative approaches to engaging communities and tapping into the best and brightest in academia and beyond within the NY Rising competition.

The places in which we live our lives are more than physical spaces; they are the context and the content of our experience. Today, simultaneous revolutions of mobility, connectivity, and identity are changing our experience of the world and, along with it, our relationship to place. Now, more than ever before, what we create will shape the way we live. At Sasaki, we harness this power to make human hopes and dreams into proven physical realities. This has been our core tenet since day one, and now, as the world changes faster than ever, we advance our shared potential through the built environment. In every project, new possibility is translated into new action. We think beyond the building, beyond the site, beyond the grid, to design for people and for society. We are at once realistic, holistic, and optimistic. We create places that prove human potential. Visit http://www.sasaki.com/blog
