User note: The WA-WUI map is available at https://geo.wa.gov/maps/786aaa1dbbd748e6ae04bc43c8f127fe/explore.
Where a structure is proposed to be constructed in an area designated by the WA-WUI map as wildland-urban interface or intermix, the construction shall comply with the provisions of this code.
302 Wildland-urban interface area designations.
Table 302.3(1)
Outline of Simplified Procedure for Determining Wildland Interface Designation
For the area to be evaluated in Section 302.3.1: |
1. Determine structure density category (uninhabited, very low, low, medium, or high). |
2. Determine vegetation density category (nonvegetated or vegetated). |
3. Determine proximity category (near or distant). |
4. Based on structure density, vegetation density, and proximity categories, determine if compliance with this code is |
5. Where compliance with this code is required, determine wildland urban interface area designation (intermix or |
UNINHABITED: | 0 structures |
VERY LOW: | 1 structure |
LOW: | 2 to 8 structures |
MEDIUM: | 9 to 120 structures |
HIGH: | more than 120 structures |
The WUIC shall not apply under either of the following conditions:
Table 302(1). Outline of simplified procedure for determining wildland interface designation
UNINHABITED | VERY LOW | LOW | MEDIUM | HIGH |
0 | 1 | 2 to 8 | 9 to 120 | MORE THAN 120 |
NONVEGETATED | VEGETATED |
Less than 50% vegetated | 50% or more vegetated |
NEAR | DISTANT |
Less than 1.5 mi (2.414 km) | 1.5 mi (2.414 km) or more |

* Structure density category is very low to high; and | * Structure density category is uninhabited to high; and |
* Proximity category is near. | * Vegetation density category is nonvegetated; and |
* Proximity category is distant. |
