Andy,
It was a typo left over from a previous plan. Ground should not be on this plan. lt should just say snow load. The roof
was design lor a 40 psf roof snow load, not ground load. Let me know if you have any question or need anything
additional.

something or other. The building code shows Ground snow loads. Garfield County has amended the code since the
beginning of time to require the Roof snow load of 40 psf for the elevation of this project. The local engineers back
calculate to get the h¡gher Ground snow loads. Please see amended 2015 IRC per resolution:

Table R301.2(1)
FLAT ROOF SNOW LOAD REPLACES GROUND SNOW LOAD as determined by

Garfield County snow load based on elevation:
To 7000ft.40psf
7001 to 8000ft 50psf
8001 to 9000ft 75psf
9001 to L0,000 100psf
Potential unbalanced accumulations of snow at valleys, parapets, roof structures and offsets
ln roofs of uneven configuration shall be considered. Minimum snow loads are in pound
per square foot of horizontal projected area .All snow load roof designs are to be designed
and stamped by a Colorado registered professional engineer or architect.
Sorry for the confusion,
Andy

J usti n,
The snow load shown on Sheet S-1 under General Notes show a ground snow load (Pg)of 40psf. Garfield County snow
load is actually a flat roof (Pf) of 40 psf. Please verify your drawings will accommodate the Pf of 40 psf .
Thanks,
