- Map It. Show where the flood waters breached the bulkheads and shorelines during Hurricane Sandy via satellite or other images. Map the flooding at peak levels. Remedies need to be based on expert analysis of this data.
- Make prevention the priority. In the U.S., disaster relief takes precedence over disaster avoidance. Learn from the Dutch who focus most of their resources on preventing future disasters.
- Work with nature not against it. Restore wetlands, make room for rivers to rise and preserve floodplains. Build underground parks that can take in floodwaters.
- Trickle down eco-nomics. Require green roofs and permeable surfaces, including permeable streets and sidewalks with catchment basins.
- Raise the revetments. Build bulkheads, seawalls & sea gates to appropriate levels based on data from Hurricane Sandy.
- Utilize soft infrastructure. Rebuild marshes and other natural barriers, like oyster reefs, that provide a buffer to storms. Create artificial reefs that can do the same.
- Eliminate combined sewer systems. Separate lines for sewage and stormwater. Ensure flood gates and pumping stations work even during a power outage.
- Increase setbacks from rivers and oceans for private development. Ban non-water dependent development of piers and platforms. Create public parkland at water’s edge designed to withstand storms.
- Batten down the hatches. Provide for sealing entrances to subways and tunnels in flood zones. Elevate entrances to subways.
- Develop microgrids. Smaller electric grids with their own source of power such as fuel cells, wind or solar can provide service when main grid shuts down. Ensure that power systems are flood-proof.
- Decrease global warming. With melting ice caps and rising sea levels, it is time to get serious about ending our reliance on fossil fuels and emitting greenhouse gases. Dirty energy is a reason why storms are stronger, floods more destructive and weather catastrophes more frequent.
- Build above base flood elevation. Municipalities must strictly enforce building codes using the new, soon to be released, FEMA flood maps; join the National Flood Insurance Program’s Community Rating System; and revise permitted uses and other zoning restrictions in flood zones.
Please give us your ideas and feedback. This list is a working document and we will flesh out the details as we move forward.
