FORM HEIGHT CONFORMANCE
Project Add res:10081 Judy Ave, Cu ertmo, CA
City of Cupertino .
This letter is to confirm in writing that jian Yang, the Registered Civil engineer (RCE) has performed a
site investigation for the foundation form at new house construction at the subject address. The
stakes and foundation form have been placed in place. We have subsequently done a foundation
verification site visit, and have determined that the contractor has formed the foundation stem walls
with the elevation in accordance with the city approved plans. Specifically, the house elevation was
placed in the following positions.
1, Assumed Zero (0) Elevation: The average top elevation of the front concrete curb & gutter is
assumed as of 0.00' for the purpose of determination of finished floor elevation:
2, The city approved plan shows the Finished Floor (FF) shall be minimum 20" (1.67') above the
adjacent finished grade, and the finished grade shall be minimum 3" (0.25') above the Top of front
concrete curb & gutter for the drainage. Thus the FF elevation shall be 23"
3, The RCE verified in field that contract now has a form setting up with concrete stem top elevation
at 13.25" above the assumed zero elevation at front curb, with the rest of 9.75" from the ntndsill
(1.5") + floorjoist (7.5") + plywood (0.75"). That will outcome the FF elevation at 23".
This is to certify the final finished floor elevation will conform with the city approved floor plan.
Note: All dimensions are given to the nearest 0.05 feet.
Please contact me should you have any question. Thank you very much.
