Key Points
- Navigational access of approximately 13 feet
- Constructing new support elements in line with existing will provide for minimizing impacts for boaters during construction
- Typical sections which provide for safety of all users
- Developed features which enhance aesthetics
- Develop Design which can be constructed while maintaining access during construction
- A resilient design to maintain access during its’ service life
- Survey Results will be posted after the meeting
