Yucaipa Zoning Code · 2026-06 edition · updated 2026-09-10 · Yucaipa

The City may consider Effective Precipitation (25% of annual precipitation) in tracking water use and may use the following equation to calculate Maximum Applied Water Allowance:

MAWA = (ETo-Eppt)(0.62)[(0.55 x LA) + (0.45 x SLA)] for residential areas. MAWA = (ETo-EPPT)(0.62)[(0.45 x LA) + (0.55 x SLA)] for non-residential areas. (Added by Ord. 338 § 1, 2015)
