ROCKAWAY WATER PLAZA Sustainable Redesign of a Vacant Plot In - PowerPoint PPT Presentation

ROCKAWAY WATER PLAZA Sustainable Redesign of a Vacant Plot In Arverne Zoë Piccolo Sustainable Environmental Systems Capstone Produced for Pratt Institute and the Rockaway Waterfront Alliance SPRING 2017

AGENDA 1. Delta City Challenges 2. Case Study 3. NYC Initiatives 4. Rockaway Background 5. Client and Project Site 6. Designs and Calculations 7. Challenges 8. Recommendations

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) SPRING 2017 4

ROCKAWAY PENINSULA/JAMAICA BAY • 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 SPRING 2017 7

MARITIME GRASSLAND 1. Juniperus virginiana - Red Cedar 7. Lespedeza capitata - Bushclover 2. Prunus serotina - Black Cherry 8. Oenothera biennis - Evening Primrose 3. Myrica pensylvanica - Northern Bayberry 9. Ammophila breviligulata - Beachgrass 4. Gaylussacia baccata - Black Huckleberry 10. Schizachyrium scoparium - Little Bluestem 5. Solidago sempervirens - Seaside Goldenrod 11. Panicum virgatum - Switchgrass 6. Aster ericoides - Heath Aster 12. Sorghastrum nutans - Indian Grass SPRING 2017 22

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 SPRING 2017 24
