Benefits of Sustainable design interventions Advantages:
Heat in calories removed if 0.2 inches of water evaporates on a sunny day.
• Reduces the surrounding temperature, reversing the urban heat island effect. • Reduces air conditioning demand. • Captures stormwater to mitigate runoff impacts. • Increases lifespan of the roofing material.. • Increases the real estate value of the project site and its surroundings.

ROCKAWAY PENINSULA: BACKGROUND STUDY REPORT Graduate project Oct - Nov 2019 Pratt Institute Project Type: Individual Project Professors:
Case Wise
Project Description: This report is a study to understand the Rockaway Peninsula region within various dynamics. The report focuses on multitude of issues like the fault line of class that runs through the peninsula, the increasing rate of poverty, the social as well as the economic divide, along with which the physical issues like the flood prone areas, land use and the probability to build resilient infrastructure. This study acts as a baseline analysis to already prevalent issues at the Rockaway Peninsula.
Skills: Maps: ArcGIS, Photoshop.
Rockaway Peninsula is predominantly covered with residential cover, taking up
35% of the total area, on the contrary, commercial buildings cover only 1.5% of the total area. The another shockingly interesting data is a large number of vacant lots summing up to 9% of the entire area. These could be the potential sites for developing resilient infrastructure. The frame on the map depicts the maximum concentration of vacant lots.
