1 Five Places in New Yorks Hurricane Alley Association of American Geographers Spatial Thinking and Hurricanes – Module 8

2 Five places near the shore in Staten Island. The numbers on the contour lines indicate feet above sea level.

3 This beach is south of the Verrazano Narrows Bridge.

4 The Bridge connects Staten Island with Brooklyn.

5 The city built a boardwalk along the shore.

6 The boardwalk is strong and well-braced.

7 Tall marshgrasses grow near the shore.

8 Place A Elevation 7 Feet

9 Some houses near Place A are low; others are high.

10 These new houses are built above their garages.

11 A low house next door is vulnerable to a storm surge.

12 People have to climb 12 steps to go into this house!

13 Place B Elevation 10 Feet

14 This house near Place B is 9 steps above the ground.

15 These nearby apartments are above their garages.

16 Place C Elevation 15 Feet

17 Place C is right at the edge of the danger zone.

18 These apartments are between Place C and the ocean.

19 The land rises as you go northwest from Place C.

20 Houses on top of the hill are built right on the ground.

21 Place D Elevation 20 Feet

22 Houses near place D are built just a few steps up.

23 Place E Elevation 40 Feet

24 Apartments near Place E are safe from a storm surge.

25 The land farther from the shore is even higher.

26 This old fort was built on the hillside near Place E.

27 Conclusions Some people live close to the ocean just south of the Verrazano Narrows Bridge. Maps and scientific models clearly show that this area is vulnerable to a hurricane storm surge. Even though hurricanes are rare in New York, many people here design and build houses high enough to be safe from storm surges.

28 New York City has designated evacuation zones for hurricanes of categories 1, 2, and 3 (lightest blue). www.nyc.gov/oem/he/index.htm

29 Problem: some houses in the storm-surge area are low and vulnerable. What is a fair thing to do about them?

30 Is it fair to require every new house to be built high enough (and strong enough) to be safe from a storm surge?

31 While we are looking at this house, here is another question – what will a 100-mph wind do to all these overhead wires?
