The spatial extent of the polygons in this dataset originates from the CII regions of the CII AOI dataset for the supplier. The creation of the polygons in this dataset is based on 2020 4-band 1-foot aerial imagery. The minimum mapping unit (mmu) is 64 square feet. This mmu is adhered to during manual review and editing, though polygons smaller than this may occur in the dataset and remain as artifacts from the modeling process. This dataset was generated as part of the California Department of Water Resources (DWR) Agreement #4600015006. Under the DWR Agreement #4600015006, and as part of the response to the State Water Resources Control Board (State Control Board) Drought Emergency Regulation (California Code of Regulations [CCR] Section 996), new requirements for urban retail water suppliers under California Water Code (Water Code) Section 10609.10(d)(2), and DWR's responsibility to provide technical assistance, including data, to urban retail water suppliers (Water Code Section 10609.26(a)(4)). DWR partnered with NV5 (NV5) to provide timely and necessary CII landscape area measurement (LAM) data: A. To urban retail water suppliers for their use in managing CII outdoor water use during drought and long-term resilience, and B. For the State of California (State) analysis of CII landscape water use and conservation potential during drought and for long-term efficient water management.

The California DWR acknowledges that since this dataset was generated using 1-ft resolution 2020 imagery and spatial information representing the supply area from the URWS, the accuracy of this dataset compared to actual ground conditions is dependent on this source information. The California DWR encourages URWSs to use this data as a tool in conjunction with other tools to best support their compliance with the State Water Resources Control Board Drought Emergency Regulations.

Once in hand, the California DWR checks these datasets and provides feedback to NV5. NV5 incorporates all California DWR feedback prior to finalizing datasets. Data is complete as of publication. The dataset was created using imagery with 1-foot resolution. This dataset was created by selecting the turf polygons (classes 3A and 4A) from the final LUCD dataset. 2023-11-01 8902 Functional_Turf LUCD Polygons with Functionality NV5 FID Internal feature number.
