The ‘A’ to ‘V’ relationship table can be used to connect residential LAM parcels to their topologically corrected extensions using the NV5-generated parcel identifier (“A_UID”) and extension identifier (“V_UID”). 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.
