Tiers 3 and 4 represent inefficient and excessive usage above your water budget. Tier 3, or usage above Tier 2, is calculated by adding half of Tiers 1 and 2 together. Tier 4 is any usage above Tier 3.

Budget-based tiered rates reward customers for using water efficiently. The District uses publicly available data to estimate your indoor and outdoor water needs - your water "budget" - and charges lower rates for this amount of water usage.
We don't! We estimate your water needs, and then charge lower rates for the water you use to meet your needs based on these estimates. Our estimates are based on State of California standards for efficient residential indoor and outdoor water use. The following is how we calculate your efficient indoor and outdoor water needs.
We use lot size, original structure, and additional hardscape (30% remaining area). The District estimates irrigated landscaped area by using information from the San Bernardino County Assessor’s Office. We take your lot size, then subtract the square footage of the original dwelling structure built on the property, and then subtract 30% of the remaining area for additional hardscape (additions, garages, driveways, sidewalks, etc.). The result of that calculation is your estimated irrigated landscape.
