Parcel Data and Building Design Criteria

PARCEL DATA AND BUILDING DESIGN CRITERIA

To display the building design criteria (ground snow, wind speed, seismic design category, fire severity, flood and climate zones) for a specific parcel:
	Enter Parcel Number: (also known as Assessment Number) (You may enter the first 8 or 9 digits of the APN (for example: 00789012 or 007890012). Do not include hyphens (-), spaces, alphabetic or special characters. If there are leading zeroes, as shown in the example, please be sure to include all zeroes.)

2019 California Building Codes (CBC) effective January 1, 2020

SEISMIC ZONE **	To be determined using the CBC section 1613 earthquake loads. Except: Effective June 10, 2016, parcels in Tahoe within Alquist-Priolo Earthquake Fault Zones require a Geologic Report.
BASIC WIND SPEED (3 second gust) Special Wind Region Map [.pdf, 4.39 MB] NOTE** The maps are currently unavailable and we are working on the issue.	El Dorado County's minimum wind speed shall be determined from CBC Figure 1609.3 or CRC Figure R301.2(5) except in the Special Wind Region (eastern area of the county). The Special Wind Region basic wind speed is 130 mph.
SOIL BEARING Seismic Design Category Map [.pdf, 8.33 MB] NOTE** The maps are currently unavailable and we are working on the issue.	Commercial 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. Additional grading information.
	Tahoe 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.
	West Slope Single Family Dwelling 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 soil bearing criteria >1500#'s per sq. ft. requires a soils report supporting the values used in the design.
CONVENTIONAL LIGHT FRAME CONSTRUCTION	California Building Code, section 2308, requirements. (Note: not applicable if ground snow is greater than 50#’s per sq. ft.)
GROUND SNOW LOAD **	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.
FROST LINE	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.
FLOOD ZONES	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. Flood Zone Definitions
CLIMATE ZONES	Climate Zone 12 Climate 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 zone 12.
CLIMATE ZONES	Climate Zone 16 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.
FIRE SAFE REGULATIONS	The State of California Board of Forestry established firesafe measures to protect homes in the wildland fire areas. These measures shall provide for emergency access; signing and building numbering; private water supply reserves for emergency fire use; and vegetation modification. Firesafe Regulations Driveway Slope. Contact you local Fire District for any additional information and regulations concerning your parcel
FIRE HAZARD SEVERITY ZONE	As of January 1, 2008 building codes require additional building modification to meet requirements of Wildland-Urban Interface Building Standards.
FIRE SPRINKLER REQUIREMENTS	Permit applications after January 1, 2011 will require fire sprinklers installed in all Single Family Dwelling and attached garages.
ZONING SETBACK	If the lot/plot is one acre or greater, the minimum setbacks to the property line must be thirty feet to meet the California State Firesafe regulations. (see above) All other zoning setback requirements are established by Planning Services and must be indicated on the plan set. Measuring Building Setbacks
RADON GAS	Radon gas may be associated with new construction.
WATER DISTRICTS	If your project is within a water district and not on a well, contact the district for additional information and requirements.
GENERAL PLAN REQUIREMENTS	Requirement of the General Plan may affect your building design because of location on the property. See the General Plan Residential Checklist for residential parcel specific information. See the General Plan Non-Residential Checklist for non-residential and multi-family and commercial parcel specific information.
Buildings not designed by a State of California licensed architect or engineer must meet the requirements of a conventional light frame and brace wall construction design as outlined in the 2019 California Building Codes, Part 2, Vol. 2 § 2308 or the 2019 California Residential Code. ** If a California licensed architect or engineer is required they shall verify the site conditions affecting the building design per the 2019 California Building Code and the 2019 California Residential Code.
