PlanninR Comments Kernen Lien:
Datum Point: Please identify a datum point on the site plan and elevation of the datum point. The
datum point should be something permanent such as a water meter, The datum point is used to verify
height during the height inspection.
A site temporary benchmark datum (TBM A) was added to the plans. SSMH in 911 Ave W near southeast
corner of the site.
Coverage: The coverage calculations for the proposed residence appear to way off. While the
residence would meet the 35% coverage requirement with the numbers provided, they should be
corrected to more accurately represent what is being constructed on the site. The coverage number
provided on the site plan is 4,150 square feet. I calculated the coverage off the site plan as
approximately 2.650 square feet Ott 1 )w�a ).l,kl_detines coverage as the total ground coverage of
all buildings or structures on a site measured from the outside of external walls or supporting
members or from a point two and one-half feet in from the outside edge of a cantilevered root,

numbers on the site plan.
Lot coverage calculations have been revised as requested, proposed lot coverage is 2,680 sf (21.34%).

Building Comments Chuck Miller:
On sheet A3:
1. Foundation Plan — Indicate on the plans the minimum required `widened' footings below
each end of the beam over the 6080 sliding glass door in the west wall of the `Bonus Room'.
The `typical' footing appears to be undersized for the loads anticipated by the represented
construction and indicated in the provided beam calculations.
Call out revised as requested; at 1313-1, additional footings have been added (see Sht. A3).
