25 June 2013 Surveyeymund.diegel@parks.nyc.gov
Field Notes: Mainly London Planes (Platanus acerifolia) and Dawn Redwoods (Metasequoia glystroboides) were impacted by salt water intrusion to their root areas.
277 Trees were mapped as impacted
Recommendations:Do nothing: Let trees go through full annual leaf out cycle to see which ones survive before replacing anything.
As capital restorationas permit, eliminate salt ponding locations to allow for better draining of flood salt waters. DEP currently has Green Infrastructuredraining reconstruction project on Columbia Street between Sigourney and Bay whichshould be informed of Sandy's lessons before replanting. There is also proposal for a new park and regrading of Gowanus Bay Terminal as part of EPA Gowanus Superfund Cleanup that should integrate Halleck Street and Columbia salt water draining issues.
Most impacted areas are Red Hook Houses at Dwight and King Street and Red Hook Park.
These were built on the old Seabrings Tidal Mill ponds, so settlement and ponding of salt water in these locations was variable on tree health
