This important sub area includes the design of a new cantilevered boardwalk that would
connect Main Street to the proposed path in area 7. The boardwalk structure will match
the general design of the other proposed boardwalks, Conceptual evaluations point to a
structure that is entirely supported by the adjacent building without need for in-water
supports. The design will include a raised deck area behind the restaurant. HL Turner will
lead the design. VHB will provide input on the boardwalk profile and how and where it
touches down at the proposed paved path. VHB will provide the 3D terrestrial point cloud
survey. The City will provide any required coordination with the building owner and
required property agreements.
Lead Consultant: HL Turner
Support from: VHB
2.12.7 — Multiuse Path
VHB will design a multiuse path from the end of the boardwatk in area 6 to Front Street
and the boardwalk behind the substation. The existing unpaved path does not appear io
meet ADA requirements so VHB will propose profile improvements and an alignment shift
to avoid or minimize floodplain and wetland impacts.
Lead Consultant: VHB
Support from: HL Turner
2.12.8 — Substation Screening
Halvorson will complete the preliminary screening design. Halvorson and the City will interface
with Eversource.
Lead Consultant: Halvorson
2.12.9 - Boardwalk and Floating Dock
HL Turner will lead the design of a boardwalk connection along the river by the substation.
This boardwalk is an alternative to having the path run past the front of the substation
along Front Street. VHB will provide input on the boardwalk profile and how and where it
touches down at the proposed paved path and by the substation. We understand that HL
Turner will be providing bathymetry from FEMA, which will help them understand river
depths where the boardwalk will be over water. HL Turner will arrange geotechnical
services for the boardwalk supports.
