 "description": "Overview:This is an analysis of proposed Zone 0 regulations (presentation link is here) which calls for the significant removal vegetation within 5 feet of a structure (including the structure itself).  Building footprints within a very high fire hazard severity zone were selected out and coded with community names from the Countywide Statistical Areas layer.  A buffer of 5 feet (including the building footprint) was run for unincorporated areas and intersected with a tree canopy.  This intersection depicts the impact of vegetation removal resulting from the proposed Zone 0 regulations.  A summary by community with an acreage breakdown was also generated.This is a simplified version of the layer to reduce the file size in order to improve map service performance.  The simplification tool algorithm used was 'Retain critical bends (Wang-Muller) with a simplification tolerance of 2, and a minimum area of 10 sf.Datasets used:Building Outlines - 2023 LAR-IAC datasetFire Hazards - Combination of existing State Responsibility Area fire hazards and proposed Local Responsibility Area fire hazards.  Very High Fire Hazards queried out.Tree Canopy - 2020 dataset from DudekLayer created on 7/22/25, and copied to SDE",
