WATERSIDE DISTRICT

Back

The current proposed project feature is a binwall that will serve as the future promenade behind Waterside District. Once the project has been constructed the binwall will be at the elevation of the first floor of the existing building structure. Therefore, when you exit the building, you will essentially be walking on top of the floodwall (binwall) similar to the Virginia Beach boardwalk structure at the oceanfront. In order to meet the design elevation for the project, we would like to use a deployable flip up gate that is recessed into the top of the binwall. This design feature would be placed strategically where existing doors or windows exist today. The goal is to preserve the waterfront views and aesthetics that define the character and charm of our downtown.

Fountain Park to Otter Berth

In Phase 1B, as you move away from the Waterside District, you arrive at Fountain Park. This is where the floodwall transitions from a bin wall to a T-wall, incorporating strategically placed openings to allow pedestrian and vehicle access. In the image shown, the pump station is represented by a grey box. However, we are actively working to eliminate this infrastructure by redirecting water volumes to a new pump station located farther east along Waterside Drive.

Waterside Drive and TownPoint Park

Back

The original feasibility study recommended a levee through Town Point Park. However, due to its substantial footprint and real estate requirements, the levee posed significant challenges to the functionality and accessibility of this iconic city park. Currently, Phase 1B is being designed by USACE consultants, and the levee may be reconfigured into a floodwall. While a traditional T-wall offers structural benefits, it presents similar concerns regarding safety and park usability. To address these issues, the City is proposing the use of deployable flip-up barriers in this location. This solution would preserve access to the park during major events and maintain the picturesque viewshed that defines the area’s character.

B. Modified Feasibility Study Alignment

C. Over-Water Alignment

A. Current Feasibility Study Alignment

• Outlined in the USACE Feasibility Study. • Consists of T-walls and a shorter in-water storm surge barrier on the north side of the W. Brambleton Ave bridge. • +/- 23 gate structures; 17 vehicular, 4 pedestrian, 1 tidal flow (non-navigable), and 1 navigational.

C. Over-Water Alignment

• Potential for raised park and elevated trail minimizing viewshed impact for ERT users.

• Increased number of residential properties within the line of protection.

• Significant reduction in utility conflicts overall.

• This is the preferred alignment of the community and city leadership.

B. Modified Feasibility Study Alignment

• Maintains public waterfront access at Wisconsin Square.

• Decreases a small number of residential property impacts however, it does not reduce a substantial amount of property impacts.

• Reduces various utility conflicts by avoiding Boush Street but a substantial amount of conflicts remain under this design option.

C. Over-Water Alignment

Bypasses much of the Current Feasibility Study alignment, reducing utility conflicts, impacts on traffic, historic neighborhood impacts, and challenges with private property real estate. • Consists primarily of a storm surge barrier with one large gate for vessel traffic and multiple tide gates to maintain water quality. • +/- 4 gate structures; 2 for tidal flow, 1 navigational surge barrier, and 1 vehicular.

B. Modified Feasibility Study Alignment

Though similar to the Current Feasibility Study alignment along much of its length, this Modified Feasibility Study alignment seeks to reduce the impact on utilities, traffic patterns, and structure while improving life safety. • Consists of T-walls, bin-walls, and a storm surge barrier on the south side of the W. Brambleton Avenue bridge • +/- 14 gate structures; 9 vehicular, 4 pedestrian, 1 tidal flow, and 1 navigational
