Justification for Dredging: The navigation channel is reduced to 220’ between the 9.0’ contours and 120’ between the 10.5’ contours.

 

MATERIAL PLACEMENT DATA

Proposed Placement Site: Winona Technology Park and Homer

Location: 6-722.9-RMP and 6-720.5-RMP

Site Characteristics:  Winona Technology Park is a site provided by the Winona Port Authority.  The Winona Port Authority has obtained all necessary permits for this action. The East End Boat Harbor (RM 723.6) is the offload site and material is trucked to Technology Park.

 

Homer is a historically used beneficial use placement site.

 

Our hope is to only use Winona Technology Park but Homer is listed here in case the water comes up too high to offload at the East End Boat Harbor.

 

If you have any questions concerning this project, or if you would like to request an on‑site meeting, please call a dredging manager at (651) 290-5155.
