recommendations. VHB will also coordinate with the City to ensure the new ramp will not
impact the existing sewer line in the area. A detailed structural design scope is attached as
an exhibit.

2.12.17 - 60 Main Street Boardwalk and Trail
HL Turner will lead the design for the boardwalk and associated ADA ramp that will
account for the elevation difference between Main Street and the parking lot behind 60
Main Street. VHB will provide input on the boardwalk profile and how and where it
touches down at the proposed paved path. HL Turner has determined that supports will
not be needed in the river and that the building will support the boardwalk. VHB will
provide a terrestrial point cloud survey.
VHB will provide design of the path than will lead along the river from the ADA ramp to
the ADA ramp behind the library. This path may result in utility pole and/or parking lot
impacts, and it should also be designed to minimize fill in the floodplain if possible.
The City will provide any required coordination with the building owner and required
property agreements.
Lead Consultant: HL Turner for the boardwalk, VHB for the trail
2.12.17a - Pearson Ave Alternative Connection
In the event the 60 Main Street boardwalk and path along the river described above are
found to be infeasible, VHB will direct fts attention and the associated design fee to an
alternative pedestrian connection along Pearson Street instead.
Lead Consultant: VAB
2.12.18 - Wayfinding
At the City’s direction wayfinding will be added to the scope of services during final
design.

2.2, River Hydrology
Any of the design that would result in fill within the floodplain and floodway must be
coordinated with HL Turner since they will maintain the river hydraulics model.
