Parcelization (Tile Layer)

This dataset is available for download from:  Parcelization (File Geodatabase) Parcelization, a measure of size and density of parcels  in a localized area,  is a development feasibility factor that is  used in evaluating substations’  ability to support new  utility-scale  resources in long-term energy planning. A s tatewide  dataset of parcel boundaries  are  used to develop this index. The  parcel s   are converted  into  a 90-meter raster,  containing  values  of a unique identifier reflective of  Parcel APN. A  focal statistics tool is used to count the number of unique parcels within a  0.5 mile  radius of each  parcel. This output  is provided here  and is an intermediate output to the final  parcelization  map. Users who wish to use this  information  to produce the final map should overlay parcel  boundary  data  and extract the mean  raster value within each parcel. The map is limited to the area considered with  solar  technical resource potential  after a minimum  set of  land- use screen s (referred to as the Base Exclusions)  has  been applied. More information on the methods developing this dataset as well as the  main use of this dataset in state electric system planning processes can be found  in a recent  CEC staff report  and  workshops supporting the resource-to-busbar  mapping methodology  for the  2024-2025  Transmission Planning Process.
