Research shows that leaving the final 3-5 feet around a house free of vegetation and filled with hardscape materials such as gravel, pavers, and concrete walkways is most effective. The Colorado State Forest Service provides comprehensive guidance on home hardening in their Home Ignition Zone guide.Ĭreating defensible space involves modifying the vegetation around a home to slow or prevent the spread of fire. Existing homes can be improved by retrofitting vulnerable areas, replacing unscreened vents with screened ones, caulking gaps in the siding, and swapping out combustible fencing with noncombustible versions. For new constructions, this might include using non-flammable materials for roofing, siding, and decking, and installing multi-pane windows. Home hardening involves making modifications to a home or other structures to reduce their ignitability. The two primary methods are home hardening and creating defensible space.

However, homeowners can take proactive steps to reduce the risk and potential damage caused by wildfires. They can be particularly destructive in areas with heavy and continuous fuels, such as grass and trees, as well as man-made structures like fences and buildings. Wildfires have been a longstanding part of Boulder County's natural ecosystems.
