California has adopted the toughest rules in the country to help protect communities from burning. Homeowners in wildfire-prone areas will be required to limit plants within five feet of their house, a protective measure that wildfire experts say can help prevent homes from igniting. …Wednesday’s vote by the California Board of Forestry and Fire Protection comes after years of debate and delays. The state originally considered rules that would have restricted all vegetation within five feet of a house, aside from well-maintained trees. That generated pushback from some communities. …California regulators ultimately struck a compromise. Lawns, flowers and non-woody plants up to 18 inches tall will be allowed, unless they are located directly under the roofline of a house. Trees will be allowed, though branches must be trimmed five feet away from a structure. The rules will apply to new construction right away, but will be phased in for existing structures.
