Note the current version needs to remove the water budget language since they don't have water budget based rates. Looking at this sentence:

"Billed amounts may vary based on actual water usage, actual evapotranspiration rates, any changes in household size or irrigable area, and/or days in the billing cycle."

It might be useful for SMC to deploy a "what if" bill calculator showing what it would look like if the city had budget based rates
