Fire
Prevention Landscaping and Construction
Summer is here & this is the time of year that rural fire danger
increases. Prospective real estate buyers should keep the following
in mind whether they have already purchased or plan to soon purchase
rural properties.
When designing and installing landscape, consider the following:
Local area fire history; site location and overall terrain; prevailing
winds and seasonal weather; property contours and boundaries; native
vegetation; plant characteristics and placement and irrigation requirements.
Be sure to leave a minimum of 30' around the house to accommodate
fire equipment, if necessary. Carefully space the trees you plant.
Take out the "ladder fuels" such as vegetation that serves as a
link between grass and tree tops. It can carry fire to a structure
or from a structure to vegetation. Give yourself added protection
with "fuel breaks" like driveways, gravel walkways and lawns.
When maintaining landscape, keep trees & shrubs pruned. Prune
all trees up to 6'-10' from the ground. Remove leaf clutter and
dead and overhanging branches. Mow your lawn regularly. Dispose
of cuttings and debris promptly, according to local regulations.
Store firewood away from the house. Be sure the irrigation system
is well maintained. Use care when refueling garden equipment and
maintain it regularly. Store and use flammable liquids properly.
Dispose of smoking materials carefully. Become familiar with local
regulations regarding vegetative clearances, disposal of debris
and fire safety requirements for equipment. Follow manufacturers'
instructions when using fertilizers and pesticides.
When considering the structure, remember the primary goals are
fuel and exposure reduction. Use construction materials that are
fire-resistant or non-combustible whenever possible. For roof construction,
consider using materials such as Class-A asphalt shingles, slate
or clay tile, metal, cement and concrete products, or terra-cotta
tiles. Constructing a fire resistant sub-roof can add protection
as well. On exterior wall cladding, fire resistive materials such
as stucco or masonry are much better than vinyl which can soften
and melt. Consider both size and materials for windows; smaller
panes hold up better in their frames than larger ones; double pane
glass and tempered glass are more effective than single pane glass;
plastic skylights can melt. Cover windows and skylights with non-flammable
screening shutters. To prevent sparks from entering your home through
vents, cover exterior attic and underfloor vents with wire mesh
no large than 1/8"; make sure undereave and soffit vents are closer
to the roof line than the wall. Box all eaves but provide adequate
ventilation to prevent condensation. Include a driveway that is
wide enough- 12' wide with a vertical clearance of 15' and a slope
that is less than 12% to provide easy access for fire engines. The
driveway and access roads should be well-maintained, clearly marked,
and include ample turnaround space near the house. Also consider
access to water supply. Inspect your property and clear dead wood
and dense vegetation from at least 20' from your house.
