Tree maintenance

Trees have many beneficial qualities, including their ability to absorb solar radiation and provide shade. From a fire safety perspective, trees overhanging a home can cause physical damage to the house from branches rubbing on the roof or walls, but more importantly, they produce leaves and debris that accumulate on the roof, in gutters, or the surrounding landscape. For these reasons, it is recommended pruning trees or branches that overhang any roof or deck. A healthy and lush green tree canopy itself is not a concern.

To maintain the benefits of the shade tree while simultaneously increasing fire safety, plant new trees in Zone 1, prune the lower limbs of existing trees, especially the ones close to the house, shed, or fence. Remove vegetation, vines, and other potential fuels that would allow for fire to move from the ground to the upper portion of the tree (i.e., the tree crown). If a tree is diseased or showing signs of decline, consider its removal or replacement.

The crown of a tree should be at least 10 feet away from the nearest structure. This reduces the volume of litter drop on the roof and deck, reduces the potential for falling branches to damage the roof, and protects the foundation from root growth.

As plants and trees age, they shed bark, limbs, and leaves. These materials become fuels over time. Keep in mind that some tree and shrub species, such as Italian Cypress and junipers can easily mask their dead materials. Gardeners often miss dead accumulations that are receptive to embers. Maintenance of vegetation near the home is critical.
