Help First Responders Find Your Home!

Install Reflective Address Signs that they Can See in the Dark and Through the Smoke

First responders need to be able to find your residence at any time – but especially in emergencies. The more you help make their job easier, the faster they can move through neighborhoods helping everyone. These are RULES – not suggestions.

4” Reflective numbers on a contrasting background, double-sided. Common sized aluminum green signs are 6”x18” or 6”x20”

Property Placards

Because many Napa County properties are located up long driveways or behind locked gates, it’s imperative that First Responders are provided key information that will assist them in accessing your property in a time of emergency. Information related to water sources, turnarounds for fire apparatus, number of buildings, or special instructions pertaining to your property are all critical pieces to ensuring safety to person and property.

Common sizes of green signs are: 12”x18”, 12”x24”, and 18”x24”. Reflective lettering sizes range from 3”, 2.5”, and 2” depending on the length of verbiage relevant. These signs are ideally placed at the gate entrance of a property.
