Saint Helena Rd Shaded Fuel Break

Upper Mark West Watershed Fire Safe Council

St Helena Road Corridor Risks

 High Fire Severity Zone by CAL FIRE  Top priority of Upper Mark West Watershed (CWPP)  Top priority in CAL FIRE's Sonoma Strategic Fire Plan  Overgrown vegetation creates difficult ingress and

egress for both emergency vehicles and residents

 Residents need to evacuate safely  Emergency responders need to gain entry without

excessive risk to crews

Shaded Fuel Break – Fuel Reduction

 Reduce's duration and intensity, fuel ignitability, and

wildfire spreading from the surface to canopy

 Can reduce fire intensity by the elimination of ladder

fuels

 Ladder fuels, small trees and brush removed  The effectiveness of shaded fuel breaks is improved

with width

 Power & communication lines will have increased

protection

St Helena Road Project – CAL Fire Grant

 Fire Safe Sonoma to submit grant to CAL FIRE  Treatment to 30’ from pavement on both sides  Work provided free of charge to property owners  Work will be done according to CAL FIRE standards  Helps defensible space for structures <30’  Comply with homeowner’s insurance standards for

renewing policies and avoiding cancelations

Project Specifics

 Early summer over 2+ years with contractors, fire

fighters, residents, and community members

 15’ vertical clearance upward from road  Small limbs cut back to tree trunk  All ground cover (ivy, grass, etc.) cut to <4 inches

height

 Vegetation treatment to 30’ from road on both sides  Trees <4” diameter at 4’ above ground removed

Project Specifics

 No tree limbs lower than 6’ off the ground  Shrubs/vegetation removed to provide 4-40’ spacing  Root balls left in place to reduce erosion  Remove dead/dying trees or potential to fall into the

road

 Biomass created chipped and left on site unless:

 Landowner preference is not to leave it on site  Environmental mitigation requires it to be hauled away

Environmental Specifics

 Contracted professional forester available for homeowners to

develop specific treatment plans in the 30-foot perimeter. Homeowners to review and approve treatment plans before work initiated.

 Work done according to CEQA (California Environmental Quality

Act) guidelines and environmental review.

 Consultants provide input and oversight to ensure that

vegetation removal does not cause erosion issues on homeowner’s property or create additional erosion concerns for properties along Mark West Creek.

Homeowner Specifics

 Provided free of charge to property owners  Stop at fences (0-30 feet from edge of road) unless

property owner agrees to treatment

 Treatment will stop where erosion potential present  No vegetation removed from fences without owner

approval

 Improves defensible space if structures <30’ of road  “Green Fences” (bamboo/oleander) removed only

with homeowner approval

What We Want To Avoid-Burned Ladder Fuels

The Goal

Frequently Asked Questions:

 Will we be allowed to do fuel removal within the

riparian corridor due to county restrictions

 The Riparian corridor restrictions appear to be

primarily pertaining to construction within 200’ of

• creek. This doesn’t apply to fuels reduction for fire

prevention as long as it’s not excessive. The county is working on a definition of excessive. The critical element is to maintain the shade over the creek.

FAQ’s continued

 Who will determine the criteria and limitations of

the removal of trees and brush? Will the contractors be knowledgeable and careful in their methods?

 CalFire has given general guidelines. A state environmental

review is required before work can begin. There will be a number of botany and archeological surveys prior to starting

• work. A forester will be hired in the grant supervise the

project.

FAQ’s continued

 Will the grant include herbicide treatment to prevent

regrowth of sprouts?

 No, CalFire does not support herbicide treatment as part of

the grant. However, given the community’s concern we will try to include hand-pruning of spouts to inhibit multiple

• stems. We could look at including such treatment in the

second year of the scope of work. We can also organize community workdays to do brush removal and thinning maintenance along the road. Individual property owners might want to consider using other methods (herbicide, grazing, etc.)

FAQ’s continued

 Will landowners have a voice and veto rights over

work that is proposed for their land.

Yes, there will be a lot of education and information

involved in helping landowners understand the best ways to prevent fires by fuel removal. Property owners can state their preferences. However, Sonoma County Code requires that "Flammable vegetation and other combustible growth within ten feet (10") of neighboring structures and roadway frontage shall be removed".

Next Steps

 We need signed approval forms back by November

15, 2019

 Our goal is to get agreements from >50% of the

landowners by mid-November.

 Talk it up with your neighbors!  The grant is due December 4th
