Enterprise has issued Safer and Stronger Cities: Strategies for Advocating for Federal Resilience Policy. The report

offers a menu of federal recommendations organized into five chapters focusing on infrastructure, housing, economic development and public safety. Each chapter includes a set of strategies, background on the issue, explanations of the role of the Federal Government, listing of potential allies in advocating for the recommendations, and relevant examples of current or previous local, state, and federal actions.

To better support city resilience, these recommendations include high level proposals for cities to coordinate with federal government for both legislative and agency actions, which cities can drive forward. Policy and program changes will increase or leverage investment from the private sector are highlighted. (2)

The report recommends, among other things, that the federal government should

  1. Create a National Infrastructure Bank that supports private-public investments in resilient infrastructure, including retrofits.
  2. Align cost-benefit analyses across federal agencies and require agencies to consider the full life cycle costs and benefits of infrastructure over the asset’s design life and in consideration of future conditions.
  3. Cultivate partnerships between cities and the Defense Department to promote resilience of city assets that are critical to national security and military installations.
  4. Implement a system that scores infrastructure based on its resilience to better prioritize scarce federal funds.
  5. Coordinate Federal Government grant-making and permitting related to hazard mitigation and disaster recovery. (10)

These are good proposals, no question about it. I am not too optimistic that the current leadership in Washington will heed any of them. Local partnerships with the Defense Department might have some legs in today’s environment though, particularly given recent news reports about foreign hacking into the electrical grid.

Even those who discount the global risks arising from climate change should acknowledge the need to bolster the resiliency of our coastal cities. Let’s hope we start planning for a wetter future sooner rather than later.

Floodproofing Communities

NYU’s Furman Center has released a Research Brief, Planning for Resilience: The Challenge of Floodproofing Multifamily Housing. The Brief opens,

As sea levels rise and storms become more frequent and severe due to climate change, many urban areas along the coasts and rivers of the United States are facing a flood-prone future. Especially in the older urban areas along the eastern seaboard, there is a significant stock of multifamily housing that will be increasingly at risk. Much of this housing is out of compliance with federal flood-resistant design and construction standards. Some of these buildings have housing units that are out of compliance because, regardless of their age, they were only recently mapped into the floodplain. And, even buildings that have been in the floodplain for longer may be out of compliance with the rules because their construction predated their jurisdiction’s adoption of the standards. (2)

And it concludes,

As the nation’s floodplains expand, the number and types of housing units at risk of flooding also grows. Multifamily housing makes up a larger share of the at-risk housing in the floodplain than was previously understood, and mitigating the risk to this housing and its residents presents unique challenges that local governments must be prepared to face. While there is no easy answer to how to fund the often costly and disruptive retrofit measures needed in these buildings, there are steps that local governments can take to make it easier for buildings to adapt, such as educating owners about risks, providing them with information about retrofit strategies, and helping them finance improvements. Including strategies like these in a long-term resilience plan will make communities stronger and will ensure that multifamily buildings and their residents are not left behind as flood-prone areas adapt. (10)

There is no doubt that this is right. New York City under both Mayors Bloomberg and De Blasio have taken this issue very seriously, but a lot of work remains to be done. And the odds are that the amount of work will only increase with time as sea levels rise higher and higher. Because many other local governments do not have the resources of NYC, they will get their wake up calls the hard way.

Given the broad effects of climate change, resiliency efforts would ideally be led by the federal government. But I don’t see that happening for a long time, probably after an avoidable tragedy on a large scale spurs Congress to action, notwithstanding its ideological commitments.

A Resilient NYC

Posted on by

NYU’s Furman Center released a report, The Price of Resilience: Can Multifamily Housing Afford to Adapt? It explains that storm-proofing New York City

poses several special challenges not shared by all coastal areas. First, New York City is largely built out, with much of its building stock long predating current flood-resistant design standards. Resilience in New York, then, primarily means retrofitting older buildings, not just strengthening building codes for new construction. Second, much of the official guidance about how to retrofit residential properties to reduce risk and lower insurance premiums is geared toward 1-4 family buildings, reflecting the national housing stock. In New York City, though, only one-third of the buildings thought to be vulnerable to flooding are1-4 family, detached homes. A much larger number of housing units vulnerable to future storms are located in roughly 4,500 multifamily buildings with five or more rental units. Finding ways to cost effectively retrofit these types of buildings to protect residents and reduce insurance premiums for owners needs to be central to New York City’s storm-preparedness efforts.

Finally, the extreme shortage of affordable housing in New York may make the direct and indirect costs of retrofitting particularly hard to bear. Based on current federal policy, increased flood risk requires for many buildings either investment in physical improvements or payment of higher insurance premiums. Without external funding or other relief, there is no clear avenue to enact these resilience improvements while maintaining affordability. Eliminating all units below the predicted flood level, for example, could result in the loss of thousands of indispensable housing units. Even if units are not lost, property owners may pass on the costs of retrofitting buildings to residents through a rent increase, reducing the supply of affordable units in New York City’s coastal areas. For buildings that are constrained in their ability to raise rents and raise funds for improvements, like many of the rent stabilized and subsidized buildings in the city, the financial burden of making costly retrofits might be overwhelming, leading to the conversion of those buildings to market rate (when permitted), unsustainable operating budgets that may require a bail-out, or a large number of buildings left unprepared for future storms. The costs of not retrofitting, however, may be even more burdensome: building owners may face skyrocketing flood insurance premiums if they do not retrofit their buildings.

While I am not so sure that storm-proofing will be what pushes New York City’s housing stock into the unaffordable column (I think the relentless increases in demand might just to the job for units that are not rent regulated), the Furman Center report reminds us that we have a lot to do to protect New York from the next big storm. The Bloomberg Administration did a lot in a short time to identify what the City can do to increase the City’s resiliency. Given the quality of his housing and economic development team, there is reason to hope that the de Blasio Administration will continue to tackle the threat of climate change in a productive way.

The Furman Center report provides three concrete recommendations to ensure that NYC’s large stock of multi-family housing in flood zones is protected from future storm events:

  1. The Federal Emergency Management Agency (FEMA) should modify the guidelines for its National Flood Insurance Program for coverage of existing multifamily buildings;
  2. New York City should expand its Flood Resilience Zoning Text Amendment to cover buildings in the 500-year floodplain; and
  3. The city should revisit its existing rehabilitation programs to ensure that resilience measures can be readily funded; and it should require that buildings in the 100-year and 500-year floodplains that receive city assistance have adequate emergency and resilience plans.

These all seem like reasonable policies that should be implemented asap.
