Wood board retaining wall in the old bassett's Creek channel near the mouth into the Mississippi River. photo taken 2012.oct.3
This is the only location where I have come across this unusual wood board style of retaining wall construction. Does anyone have any information as to the date this retaining wall was constructed? Please email me at email@example.com if anyone has any information on this retaining wall - or, on any retaining wall built in this manner.
Here is my guess as to why this style of construction was done here. My guess is that this style of retaining wall was chosen to deal with soft mucky soils. The boards may have been placed or pounded nearly horizonally into the soft soils. This might have maintained a stability not achievable with stone, concrete or blocks. At one time, this part of Minneapolis contained a number of lumber mills. I would guess that there may have been an abundance of odd shaped mill reject boards around this area for building a retaining wall like this. Anyone please email me to confirm or correct my guess on this retaining wall.
