The dataset used in this online map was provided by CalFire
(Last Update: SRA 2007 and LRA 2009)
Government Code section 51175-89 directs CalFire to identify areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors within State and Local Responsibility Areas (SRA and LRA).
Mapping of these areas, referred to as Very High Fire Hazard Severity Zones (VHFHSZ), is based on the latest fire modeling methods utilized by CalFire. Details can be found at CalFire's FRAP website:
Materials and Construction Methods for Exterior Wildfire Exposure:
The purpose of Chapter 7A in the 2016 California Building Code and Section R 337 in the 2016 C.R.C. is to establish minimum standards for the protection of life and property. These materials and construction methods increase the ability of a building located in any Fire Hazard Severity Zone with State responsibility Areas or any Wildland-Urban Interface Fire Area to resist the intrusion of flame or burning embers…
As of July 1, 2008, for which an application for a building permit is submitted located within State Responsibility Areas Fire Hazard Severity Zone or any Wildland-Urban Interface Fire Area the shall comply with Chapter 7A, California Building Code, or Section R327, California Residential Building Code.
Additionally, any Fire Hazard Severity Zone or any Wildland Urban Interface Fire Area designated by the enforcing agency (Local) for which an application for a permit is submitted after the application date shall comply with the provisions of the California Building Code, Chapter 7A or the California Residential Building Code, Section R327.

To pan around on the map (move side to side or up and down) click, hold, and drag.
Feature Info Pop-up
Opens when a feature is clicked on. Most features when "clicked on" will have a "Pop up". This feature provides basic information about the feature that you have clicked on.
This will collapse if you click the "up arrow" located at left-hand edge:
Located in the lower right-hand corner of the map screen:
Map Legend window in the lower right-hand corner of the map screen. All features in the legend denoted with a "check box" can be turned "On" or "Off". Only a couple of the features will be checked when the program opens. These are preset so that your computer will be able to process the data faster. NOTE: Some layers (depending on the data source and your network speed) may take some time to render.
Query a Community or Place
Query a Community or Place Tool is used to as a quick "jump-to" to a known community or a known place. Select your desired location from the drop-down menu. Click 'Get Results' and zoom to that location.
Data Summary Tool
Data Summary Tool will allow you to select features in one layer and then find features in a second layer that meet certain criteria (e.g., intersect within a certain distance). Selection tools include radius, box, shape, and attribute filters. Click 'Get Results' and export your data.
Type an Assessor Parcel Number (APN) into the search box (in this format: 123456789) and click "Go". The map will automatically zoom to the location and highlight your query.
Quick Address Search, Parcel or Coordinate Search
Select an option under the address field. Type an address (select
Address), coordinates (select Coordinate for Latitude/Longitude) or parcel number (select Data and type the parcel number in this format: 123456789) into the
Search Box (located in the upper right-hand corner of the map screen. The map will automatically zoom to the location.
Change the Basemap
You may select from a number of basemaps including HERE aerial imagery, terrain, topographic and street maps and HERE Maps roads, satellite, hybrid, and terrain.
Create Printable PDF
Create a printable version of your customized map in Adobe's Portable Document Format (PDF). It may take some time to generate the PDF.
Measure (Draw On the Map)
Select a draw tool and the window will automatically close and you can begin adding shapes to your map to highlight an area or specify a certain point. The tool will also calculate distance and area. Double click to close polygons.
Google Street View
This tool seamlessly integrates Google's Street View with your map.
Zoom to your current location and track your movements on your mobile, tablet or netbook device. When activated, your location will be identified on the map. This feature requires the user to authorize their web browser to know their location.
Quickly zoom to any saved bookmarks you created. Use the toolbar at the top of the map to create a bookmark.
Sketches within the Map Legend to enable the tool.
To create a sketch, click on the Sketch tab and click on the
Create a Sketch button at the bottom of the Sketch panel.
The Sketch panel will open on the left hand side of your map. Here you can set a name and description for the sketch.
Sketches are designed to be shared and worked on collaboratively, so by default new sketches can be edited by anyone with the sketch URL. If you would like to prevent others from editing your sketch, uncheck the box "Allow sketch to be edited by others".
Once you have set your sketch name and edit settings, click
Done to continue to the drawing tools.
Sketch allows you to create line, polygon, rectangle, oval, marker, and text annotations on your maps.
To place a marker, select
Create a marker from the tool bar and click on the map to place the marker. You can select a color from the range provided. If you need to re-position the marker, simple hover your mouse over the marker, and click and drag the marker to the preferred location.
To save the marker, click the
To draw a shape, click on the corresponding icon on the right of the sketch panel, and start drawing. You can adjust the line and fill colors and opacity of lines and shapes, and the text content of annotations.
To adjust the size or position of shapes, click on the white box nodes and drag to your preferred shape or size.
Extremely large circles may appear to be compressed if placed near the top or bottom of the map boundary; however, they occupy the same amount of area. This is due to the distortion of the web Mercator map projection.
