A fire suppression and isolation system includes an ejection nozzle, a dispersion nozzle, and a valve assembly. The ejection nozzle is positioned between a non-hazard volume and a hazard volume. The dispersion nozzle is spaced apart from the ejection nozzle and is disposed within the hazard volume. The valve assembly is arranged to control a release of a suppression medium from a container to the ejection nozzle and the dispersion nozzle, responsive to a thermal event, such that the suppression medium that is ejected from the ejection nozzle defines a fluid barrier that is disposed between the non-hazard volume and the hazard volume.

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.
