Project in the County
All commercial projects within the county
require a Soils Report by
a California licensed soils engineer as part of the permit
application submittal. The grading plans must be prepared by
a civil engineer.
Basin Single Family Dwelling General soil conditions
default in the Tahoe Basin area is 1500
#'s per square foot. The
soil bearing pressure can be increased to 2000#'s per
sq. ft. with a site visit and analysis by the project engineer. Any
design soil bearing criteria >2000#'s per sq. ft. requires
a soils report supporting the values used in the design.

General soil conditions
default exclusive of the Tahoe Basin is 1000
#'s per square foot. The soil bearing pressure
can be increased to 1500#'s per sq.ft. with a site
visit and analysis by the project engineer. Any design

|2016 California Building Code, section 2308,
not applicable if ground snow is greater than 50#’s per
All of El Dorado County is considered a snow
county with snow loads varying from 20#'s per square
foot to over 300#'s per square foot depending on
the site location within the county.
Note: the absolute
minimum roof snow load is 20 lbs/sq.ft.
||Parts of El Dorado County
may have snow coverage and freezing temperatures in the mountain
regions during the winter season. Currently the county does
not experience any frost deeper than the foundation requirement
of a minimum 12 inches into undisturbed soil for the west slope
or a minimum 18 inches in the Tahoe Basin.
|| Parts of El Dorado County have
flood zones as outlined by the FEMA
flood insurance rate maps (FIRMs) A, A1 - A5, B, C, and D.
A request can be made to Planning
Services for the flood zone of your construction site.
There are four floodways located in the county.
One floodway is located in the El Dorado Hills area and
the remaining three are in the Tahoe Basin. All construction
is prohibited within a floodway.
Zone 12 is primarily a "valley cooling" energy loss
calculation due to energy used to cool structures. All
structures west of a line drawn from Greenwood, through
the City of Placerville to Mt Aukum will be in climate
Climate Zone 16 is
primarily a "mountain heating" energy loss calculation
due to energy used to heat structures. All of the Tahoe Basin
is considered Climate Zone 16. Most structures
east of a line drawn from Greenwood, through the City
of Placerville to Mt Aukum will be in climate zone 16.
