Subject: Elevation Verification
To Whom It May Concern
On October 11, 2018, Tri-County Land Surveying Co. dispatched a survey crew to 612
9th Ave. S., Edmonds, WX
Datum (NAVD88) — Top of concrete mon in case with 1-1/2" brass cap located 140 feet
south of the intersection of Walnut St. and 9th Ave. S. Elevation = 281.27 feet.
Based on an average grade elevation of 274.90 feet, as established by Tri-County Land
Surveying. We find that the height at the peak to be 0.15 feet lower than the allowable
height.
274.90 feet (average grade elevation) + 25.00 feet (max. building height) = 299.90 feet
Asbuilt elevation at peak of roof = 299.75 feet
299.90 (max. building height) — 299.75 feet (asbuilt peak elevation) = 0.15 feet
The original topography did not have elevation shown or established by field work at the specific
location shown as A through F on the attached exhibit drawing. These elevations and the
elevation at the peak are all based on starting at the above mentioned bench mark and taking
direct shots at these positions.
Pleasecall me if you have any questions.
