Re: 650 Big Island
Retaining Wall Review
Dear Cinda:
As requested, Civil Solutions Group (CSG)has conducted a review of the existing boulder wall
located at 650 Big Island in Orono. The purpose of the review was too specifically to determine the
long-term stability of the boulder wall near the staircase that exceeded 4' in height.
The specific wall in question has been constructed to meet all minimum safety requirements as set
forth in both AASHTO and NCMA. The wall has more than adequate depth for the given wall
height. The wall is backfilled with sand, the proper fabric placed up the back of the�vall, and there
is drain tile properly placed. The overall construction of the wall is outstanding, having very tight
joint spacing and very aesthetically pleasing.
It is my professional opinion that the wall meets all minimum engineering standards and will
function safely as constructed.
If you have any questions, please feel free to give me a call.
