Mono County is rural in nature, primarily consisting of mountainous and high-desert terrain. The communities and inhabited portions of the unincorporated area of Mono County are generally located within, or in close proximity to, mountainous areas, forest-covered land, brush-covered lands, grass-covered lands, and similar lands that are subject to wildfires. In order to minimize the threat of wildfire spreading to occupied structures, and to supplement the educational and enforcement activities of Cal Fire, local educational efforts, and enforcement of, defensible space requirements are reasonable and necessary and will benefit the public health and safety.

22.020     Intent.

These fire safe regulations are intended to provide the same practical effect as the State Responsibility Area Fire Safe Regulations, Public Resources Code Section 4290, Title 14 of the California Code of Regulations (CCR) and roofing requirements as specified in Government Code Sections 51178.5 and 51189 and Health and Safety Code Sections 13108.5 and 13132.7. The regulations establish basic wildland fire protection standards in the State Responsibility Areas of Mono County for emergency access; signing and building numbering; private water supply reserves for fire use; roof covering standards; and vegetation modification.

When considering such site-specific exemptions or modifications, the Community Development director may consult with experts in the fields of wildfire protection and wildlife and botanical habitat preservation in reaching an appropriate level of modification. When an exception is requested for a site that is located within an established community, the Community Development director may consult with the designated representative of the local Fire Protection District in determining the requested exception or modification.
