Re: 3235 Graham Hill Road
File No. 000139-10000-2
Building Permit No. 2009-0332
Dear Melanie:
We have reviewed the as-built grading plan for 3235 Graham Hill Road dated 8-16-10.
We have the following comments with regards to engineering matters:
• There were significant changes to the approved driveway design that result in a
greater hard cover area than proposed. If hardcover limits are an issue with this
properry, we recommend the applicant submit updated hardcover calculations.
• An unplanned retaining wall was constructed on the south side of the house.
This wall has sections greater than four feet in height and to our knowledge,
engineered wall plans have not been provided to the city. We recommend that
the city require the submittal of wall design caiculations and as-built drawings
certified by engineer.
• The overall as-built grading plan is generally consistent with the proposed
grading plan and is acceptable from an engineering standpoint.
If you have any questions, please call me at (651) 604-4894.
Yours very truly,
�1�—����'.��__-

The sketch of the as-built retaining walls at 3235 Graham Hill Road has been provided by the landscaper that constructed
the wall. The height and separation of the wall do require engineering design and calculations. Although this information
has not been field verified, the sketch provided shows that the typical design elements were considered in the
construction of the wall.
