City of Ashland, Oregon / Fire / Wildfire Hazard Zone Expansion

Wildfire Hazard Zone Expansion
What is the Issue?
Dating back to 1992, Ashland’s Wildfire Hazard Zone overlay, or WHZ, (see map) has meant stricter building and landscaping safety measures in the hills above town. However, the WHZ area isn’t consistent in delineating flammable vegetation, land features, and other fire behavior factors inside Ashland.  Indeed, recent fire events have shown that high intensity, rapid spreading, and structure threatening fires have occurred well outside of the existing WHZ. For example, during the 2009 Siskiyou Fire, 109 homes and a school were evacuated under the threat of fire and none of these homes were in the officially designated WHZ. Additionally, none of the 11 homes burned in the 2010 Oak Knoll Fire were in the WHZ boundary. For FAQs and other issues pertaining to the WHZ, please click here. 
 
 

  
Detailed Background: Wildfire Hazard Zone Analysis
Ashland Fire & Rescue has completed an analysis to evaluate the boundary of its existing Wildfire Hazard Zone (WHZ) relative to the standards established by the Oregon Department of Forestry in Chapter 629 of the Oregon Administrative Rules (See Existing WHZ Map 1 and 2). This careful analysis that used new technology has allowed for a more critical look at what areas in the community meet the criteria for a WHZ. See the map of the analysis area here.

 
The analysis examined the entire footprint of the city and determined what areas meet the criteria to be considered a WHZ as set forth by the State of Oregon (OAR Chapter 629, Division 044). According to the State, there are four categories or “Hazard Factors” that are involved in determining the presence of a WHZ. The hazard factors include:
 
1. Fire weather
​2. Topography
3. Natural vegetative fuels
4. Natural vegetative fuel distribution 

Each of these four hazard factors are “scored” and there is the possibility of zero to three (0-3) points. After examining all four hazard factors for a geographic area, a numerical value can be assigned to each geographical area that will range from zero to twelve (0-12). If a particular geographical area receives an assigned “Hazard Value” of seven or greater, that geographic area will be designated as part of the jurisdiction’s WHZ.

Ashland Fire & Rescue recommends that the WHZ be increased to include all of the city of Ashland (see map). Doing so will enhance public safety by regulating known hazards as structures are built or modified, including:  
  1. The use of wood shakes as roofing
  2. Fire-prone landscaping. Currently, vegetation that produces severe fire behavior and spread such as juniper, cypress, blackberries, and arbor vitae are allowed unrestricted outside of the wildfire hazard​ zone. See the proposed "Fuel Break Prohibitted Plant List"
Both wood shake roof coverings and fire-prone landscaping were a major factor in the destruction of 11 homes in the 2010 Oak Knoll fire.
 
Expanding the zone would allow the Fire Department to apply for more funding based on the value and numbers of homes truly at risk in Ashland.

The Proposal: Include the Whole City

To minimize the impact of fire on our citizens, Ashland Fire & Rescue is proposing to expand the Wildfire Hazard Zone (WHZ) to encompass the entire city limits. This would eliminate hazards like wood shake roofing and flammable landscaping during new construction or remodeling over 200 square feet. The ordinance would not apply to properties where construction is not proposed, but does include any expansion of existing structures requiring a permit. What does it mean for you? See our FAQs.

The suggested expansion of Ashland’s WHZ to include the entire city has been approved by the Oregon Department of Forestry and is recommended by the local Division Chief of the United States Forest Service (see WHZ evaluation  map and 2). This expansion will be a major step in achieving an improved fire safety for the citizens of Ashland.

The New Ordinance

The new ordnance entitle "Development Standards for Wildfire Lands" is still in draft form and is available for the public here.  The ordinance codifies the fuels management objectives that Ashland Fire & Rescue has been enforcing in the current WHZ.  Here are some items that the ordinance will address. 

1.  Fire prone vegetation within 3 ft of a structure
2.  10 ft spacing from tree branches to a chimney
3.  Spacing requirements for existing fire prone trees and shrubs
4.  Additional fuel break size for lots with more than 20% slope

Every postal patron in the city of Ashland will receive a notice in March 2016 explaining the proposed changes in code.  This will be the time for you to read through the ordinance. When getting familiar with the new ordinance, please take into consideration that these changes will only apply to you if you:

 

-Increase the square footage of your home build more than 200 square feet OR build a new structure more than  200 square feet and need a permit. If either of these situations apply, you will need to comply with the primary and secondary fuel break standards.
 

-If you partition or subdivide your property, you will be required to prepare and implement a Fire Prevention and Control Plan which is includes fuels reduction on all parcels.
 

-If you are replacing 50% or more of the roof, the roof is required be a non-wood, Class A or B fire-rated roofing material.

Moving Forward
Ashland Fire & Rescue has been working closely with the Wildfire Mitigation, Planning and Tree Commissions on this process over the past year and a half.  The proposed draft ordinance is a representation of the ideals of these commissions and of the staff at the City of Ashland.  Please attend a Public Open House on Thursday, February 25th from 5:00PM-7:00PM at the Gresham Room in the Ashland Public Library located at 410 Siskiyou Blvd. This will be an opportunity to provide comments and suggestions to the draft ordinance.
