SR-75 is projected to experience an increasing risk of flooding from the ocean, bay, and groundwater due to low road elevations and rising sea levels.

Caltrans is studying ways to keep the roadway reliable over time.

This survey asks for your input on possible solutions.

Phased Adaptation Strategy

Question Title

1. Some flood-prone roadway segments along SR-75 may be protected in place first, then raised later as flooding increases. Where should early improvements be prioritized? (Rank priorities)

Question Title

2. How should construction be managed during phased improvements to SR-75?

Question Title

3. How do you feel about adding protective features such as a low wall, improved drainage, or localized roadway elevation to reduce roadway flooding?

Realignment Tradeoff Preference

Question Title

7. The overpass near the Cays is vulnerable to flooding and erosion (see image of existing condition). How do you feel about shifting it inland to widen the beach and reduce risk? (See images of potential options above)

Question Title

8. If the overpass is modified, which outcome do you prefer?

Question Title

9. When tradeoffs are required to prevent future flooding, what matters most? (rank priorities)
