Shandra,
A geotechnical assessment prepared for the proposed Grant Maurer garage at East 143
Merrimont Road has been received and reviewed by Public Works.
The report conforms to standards of sound engineering principles and practices and conforms to
the requirement of DCD for geotechnical assessment reporting.
Recommendations regarding backfill material and backfill drainage should be made conditions
for project acceptance.
In reviewing the building plans, only 2 horizontal rebars are specified for the foundation walls.
The geologist references the back foundation wall as being a retaining structure with a surcharge
reaction resulting from vehicle parking, and recommends a value for use in designing the wall.
With these issues in mind, it appears that the basement walls should be designed by a licensed
engineer. It also appears the floor joist sizes need to be identified.
In short,the geotechnical assessment can be considered adequate, but other issues still need to be
addressed by the applicant or his contractor.
Please feel free to contact me at County extension 461 if you have any questions regarding these
comments, or if you feel any features need further discussion or attention.
