The Napa City Council on Tuesday unanimously approved two separate items, one to increase rates for city water customers and the construction of a new 53-home subdivision in northern Napa. The rate increases — the first since October 2021 — will go into effect Jan. 1, 2024, and the first bills with the new rates will be in March and April. The increase will add up to about $5 per month more in the winter and $10 per month more in the summer for average residential water users. Water rate increases along similar lines will also move forward for irrigation, other commercial uses and multifamily residential customers. Additional increases will go into effect each year until 2028.
