6.2 Verify using the river hydraulic model that there continues to be “0.00 ft rise” with
the redesigned elevated walkway piles.
6.3 Develop structural details for the boardwalk/pile and associated connections.
6.4 Evaluate the proposed riverbank protection under the boardwalk and around the
piles by VHB or others for the potential of erosion and scour using the river
hydraulic model to determine bank velocities and soil shear.
6.5 Prepare final engineering drawings and specifications for City review and approval.
Segment 7 — Riverfront Path Along BAE Property
7.1 Evaluate the proposed riverbank slope stabilization being proposed by VHB or
others for the potential of erosion and scour using the river hydraulic model to
determine the bank velocities and soil shear.
Segment 8 — New River Crossing (Pedestrian Bridge)
8.1 Evaluate, using the river hydraulic model, the impacts to the floodway and the “0.00
ft rise” criteria based on moving the bridge abutment to avoid interference with the
sewer interceptor.
8.2 Provide findings and recommendations on the bridge abutment relocation, and
impacts to erosion and scour to the river side slopes and channel.
