In the event additional topographic and/or bathymeiric survey requirements are identified as
design development proceeds, they will be addressed in subsequent contract amendments.
Lead Consultant: HSI
Support from: VHB, Halvorson
Duration: Phased over 14 weeks
L3 Environmental Documentation
During this conceptual phase VHB will supplement the high-level, GIS-based environmental
resource data gathering that was completed for the Riverfront Plan with detailed documentation
and delineation. VHB wetland scientists will complete the required resource delineation and
documentation along the shoreland for survey by HSE Environmental resource and constraint
information will be supplemented using a combination of database research and
communication with local, state, and federal agencies. VHB will also review all relevant
documentation that the City may have com piled from the private developments that surround
the riverfront.
lead Consultant: VHB
Support jrom: Halvorson
Estimated Duration: 3 weeks, pending ensuing winter conditions
LA Conceptual Desian
VHB will work closely with Halvorson and H.L. Turner ta develop conceptual design plans that
include more detail than the schematics and illustrations that were in the Riverfront Plan. We
expect that the plans will initially be shown on ortho photos amended with available GIS
information and the City’s 2-foat contours since ground survey will be ongoing during the sarly
conceptual design phase. VHB and Halvorson will transition to using the ground survey
information as it becomes available from HSI.
As the design progresses the design team will be mindful of the “Six Big ideas" that were
defined during the Riverfront Plan: Connectivity, Environmental Stewardship, Access io the River,
Recreation and Green Space, Fload Resiliency and Economic Development.
Early during the conceptual design phase, the project team will complete due diligence efforts
to better understand all relevant constraints and opportunities within the project limits. The
project team will also vet design alternatives during this phase with input from the City, other
stakeholders and the public as appropriate. Deliverables during this phase will include sketch
plans and design graphics of sufficient detail to convey the intended improvements, The design
team will also develop approximately eight (8) 3D renderings of specific project features to
ilustrate the envisioned improvements to the public and other stakeholders.
