The Residential LAM classification was summarized to a topologically correct vector layer (‘V’ layer) of the residential parkway strips. The 'V' layer does not contain overlap and is appropriate to use for generating supplier-level landscape area measurement calculations. 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.

Data is complete as of publication. This dataset was generated using 2018 or 2020 1-ft, 4-band imagery. To create this dataset, GIS subject matter experts start with the source parcel dataset that falls within the supply area of urban retail water suppliers (URWS). An automated routine that creates Thiessen polygons is applied to 'grow' the parcel boundaries into all areas of the AOI that are not covered by parcels (VOID space). Then, the classified results of the Residential LAM project are summarized to the parkway strip polygons. 2023-06-30 19833 Residential_Extensions_V A collection of geographic features with the same geometry type (polygon), the same attributes, and the same spatial reference.
