Council members press staff on ERU method, equity and billing complexity

Mar 11, 2026

Councilors at the March 10 workshop questioned how ERUs and a tiered rate would be calculated and how that would affect small homeowners versus large properties; staff said the tiered approach is more equitable but requires a one‑time billing-system import of GIS data.

The full story

Council members used the stormwater presentation to probe the ERU methodology and fairness of a tiered billing structure. One council member asked staff to explain how Boerne’s ERU tiers (example 3,100 sq ft) relate to that city’s average unit and why Kerrville’s ERU is listed as 4,876 sq ft. "So how do they pick 3,100?" the council member asked; staff replied the neighboring city used its own study and tier classes, and Kerrville’s tiers reflect local parcel distributions and an ERU calculated from residential impervious area.
