RE: Retaining Walls/1�t 1300 Shoreline Drive �
Dear Mr. Brown:
Per your request I inspected retaining walls at 130Q Shoreline Drive on 07-14-05. The
boulder wall on the northwest corner of the house was not constructed properly. The
building code requires engineering on walls higher than four feet. No engineering was
presented to the city on this wall. No fabric was evident behind the wall and the lack of
this fabric has allowed soils to be washed away from behind the wall. This lack of soil is
causing the wall to fail. Failure of this wall is causing failure of a paved patio above the
wall.
The walls on the front side of the house in the garage area are also a problem. These
walls are of a manufactured type and are required to be build per the manufactures
engineering. The walls were build without any inspections by the city, so it is unknown
if the manufacturers engineering was followed. These walls are buckling and may
collapse sometime in the future.
Replacement walls must be approved and inspected by the city when under constniction.
If I can be of further assistance, please feel free to contact me at my office.
Sincerely,
����^�"`.-.
