PORCH AT 23318 96TH AVENUE WEST
Dear Ms. Saucedo:
I have reviewed the above building permit application for your illegally constructed porch for a third
time. However, I still need revisions to the following items before I can sign off:
1. Datum Point. The site plan states an elevation base of 100’ and shows the datum point to be the
centerline of the street. The datum point must be a permanent point of reference such as the top
of a manhole cover or street monument. The base elevation can either be 100’ or the listed
elevation on the marker but the height calculations for the building/addition must be derived from
the base elevation. Please revise the site plan accordingly.
2. Height Calculations. On this most recent resubmittal (9/20/07), you have shown height
calculations on the site plan that are for the detached garage, not the house and porch. On the site
plan, the height of the porch needs to be calculated relative to the datum point. Once you choose
a satisfactory datum point, the corner heights for the ‘smallest rectangle’ around the entire house
and porch must be identical on the site plan and in the ‘height calculations’ table. Also, the table
(and the elevation view drawings) must show accurate measurements for average existing grade,
maximum allowed height, and actual height of the porch.
3. Lot Coverage Calculations. The structural lot coverage calculations are incorrect. The lot area
calculation indicates a lot area of 113,300 square feet, a lot coverage of 4,608 square feet, yet a
lot coverage calculation of 34.6%. Lot coverage is defined 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 2.5 feet in from the outside edge of a cantilevered roof, whichever
covers the greatest area.” As a result, the lot coverage calculations should include the total
footprint of the existing house and garage as well as the new covered porch. Please provide the
appropriate existing and proposed lot coverage square footages and the final calculation as a
percentage of the total area of the lot.
Please make all resubmittals to a Development Services Permit Coordinator, Monday - Friday, 8:00 am to
4:30 pm, except Wednesdays when the office is closed. If you have any questions, feel free to contact me
at 425-771-0220 (x1330).
Sincerely,
Mike Clugston
