DELTA CITY WATER CHALLENGES

• Delta cities
• IPCC climate predictions:

– sea level rise – increased probability of extreme weather events

• U.N. Urbanization trends

– 53.8% (2015) > 66% (2055)

7 SPRING 2017

• Originally developed in late 1800s
• Interest declined in the 1950s-early 2000s
• Recent resurgence, increased beach attendance
• Primarily 1-2 family residential/multi family residential

/vacant/open space

• Separate sewer systems; Rockaway WWTP
• 10’ or less above sea level
• Average ~43 inches annual rainfall; 4” in July – 2.5” February

MARITIME GRASSLAND

1. Juniperus virginiana - Red Cedar 2. Prunus serotina - Black Cherry 3. Myrica pensylvanica - Northern Bayberry 4. Gaylussacia baccata - Black Huckleberry 5. Solidago sempervirens - Seaside Goldenrod 6. Aster ericoides - Heath Aster 7. Lespedeza capitata - Bushclover 8. Oenothera biennis - Evening Primrose 9. Ammophila breviligulata - Beachgrass

• 10. Schizachyrium scoparium - Little Bluestem
• 11. Panicum virgatum - Switchgrass
• 12. Sorghastrum nutans - Indian Grass

CHALLENGES

• Water table + engineered pumping system
• Land ownership
• Budget
• Community input

SPRING 2017 23

RECOMMENDATIONS

• Survey of the site
• Partner with engineering firm
• Begin discussions with City agencies
• Combination of the 2 designs is possible
• Community evaluation / vote
