4. “newjerseyization”
seawalls, groins,
and jetties
impacted the coast

5. Impacts of jetties

6. Impact of seawalls

7. Impacts of groins

8. Dangerous waters for swimmers produced by groins

9. Scuba steve and marine life affected by dredging for beach renourishment

10. Dangerous currents, but good waves

13. Impacts of infrastructures
Stabilize beach
Build-up sand
Create dredging problems
Create rip tides and dangerous currents
Cause more $ to be spent on renourishment
Leads to indirect problems ( sand harvesting=destruction of marine habitats, etc.)
Cause us to believe coastal areas are safe for development (only temporary)
