San Mateo County · San Mateo County · November 3, 2026
The question on your ballot
Shall the San Mateo County Charter be amended to add a provision to the Charter Preamble designating long-term resilience to extreme weather events as a County priority?
In plain language
Measure L would change the San Mateo County Charter. The charter is the county's basic set of rules. The change would add words to the charter's opening part, called the preamble. Those words would name long-term resilience to extreme weather events as a county priority. Resilience means being able to handle and recover from something. A YES vote adds this priority to the charter. A NO vote means this change is not made.
