A fire hazard due to Santa Ana winds is mitigated by causing the winds to flow through an evaporative barrier proximate an entrance to a canyon, thereby cooling, humidifying, and slowing the winds. Water applied to the barrier can be drawn by a pump from an underlying aquifer. Power for the pump can be provided by a windmill positioned in the path of the winds, and / or by solar panels. A mat containing seeds and / or seedlings and super absorbent polymer (SAP) can be positioned upwind or downwind of the evaporative barrier, and water can be applied to the mat, causing the winds to pass through the resulting vegetation, thereby further slowing and humidifying the winds. A thermally conductive network can cool the mat by conducting heat from the mat to the evaporative barrier. Brackish water can be directed to a desalination apparatus, and thence as fresh water to the mat.
