13.10.230   Effective precipitation.
   The director may consider effective precipitation (twenty-five per cent 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.
