4805 WATERSONG WAY - Caruso Residence - St. Lucie County, Fl
(Allterra Job No. 21-117)
Gentlemen:
This is with reference to the compacted building pad on the above referenced site.
The building pad has been prepared, examined and tested in accordance with accepted
Engineering practice and certain requirements of chapter 18 of the 2020 Edition of the
Florida Building Code.
Based on the results of the attached test reports, the one or two story building pad area
(finished grade) has been developed to a minimum soil bearing value of 2,500#/FT.2. (The
building pad area is defined as an area a minimum of five feet beyond the proposed
building lines, locations and dimensions as given by others).
It shall be the responsibility of the owner or contractor to maintain the building pad in a
manner that will preclude soil erosion.
If you have any questions concerning the above, please feel free to contact our office.
Yours truly,
Allterra Engineering & Testing
