2023 Landscape Area Measurement Final (Excel format)

This is a summary table of II, INI, and NI irrigation status classes, as well as horse corral areas, agricultural areas, and pool areas for all urban retail water suppliers. Column J of the spreadsheet is an “irrigable area” calculated as II + 0.20*INI per DWR’s recommendation in the outdoor water use standard (Recommendations for Outdoor Residential Water Use Efficiency Standard - https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/2018-Water-Conservation-Legislation/Performance-Measures/ORWUS_STD_WUES-DWR-2021-02_COMPLETE.pdf). Suppliers need to use the “irrigable area” data column to calculate efficient outdoor water use. Details of urban water use objective calculations can be obtained from DWR’s Recommendations for Guidelines and Methodologies document (Recommendations for Guidelines and Methodologies for Calculating Urban Water Use Objective - https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/2018-Water-Conservation-Legislation/Performance-Measures/UWUO_GM_WUES-DWR-2021-01B_COMPLETE.pdf).
