Observations/Finding

At the request of the client’s representative, ASEC representative Ram Mogulla visited the job site to assess the subgrade condition of the area where a landscape retaining wall was planned.

The landscape retaining wall was planned to be less than 4 feet high and was approximately 130 feet long. The wall extended to cover the entire back side of Lots #132, 133 and partially 134 on River Rock Road.

The undersigned representative assessed the subgrade along the wall foundation and observed approximately 6 inches of soft inundated material. This material in its current condition was not suitable to support the wall. We recommended approximately 6 inches of material be removed to expose firm subgrade soils and to replace with drainable material such as #57 stone or larger rock.

During wall construction we recommend installing 2 feet of drainage material (#57 stone) behind the wall to aid future drainage.
