Feature Class Version 6.2 (Build 9200) ; Esri ArcGIS 10.5.1.7333 gas_DIMPGrid Represents polygon grid cells used to support Distribution Integrity Management Program (DIMP) analyses, surveys, and operational risk assessments. Contains survey-related indicators, status tracking fields, QC attributes, and lifecycle metadata. Spatial reference is EPSG:2284 (NAD83 / Virginia South, ftUS). The gas_DIMPGrid feature class contains polygonal grid cells used by the utility to support the Distribution Integrity Management Program (DIMP). This grid provides a consistent spatial framework for tracking inspections, surveys, material assessments, high-pressure system evaluations, public building evaluations, and other risk-related datasets required under federal and state pipeline safety regulations. Each grid cell stores indicators representing the presence or completeness of various assessment types-residential, business, ductile iron, high-pressure, and public-building surveys-along with status fields and QC checks. Additional temporal fields track when surveys were performed or completed. This structure supports analytics, compliance tracking, prioritization of field activities, and risk scoring across the service territory. Geometry is maintained in NAD83 / Virginia South (ftUS) projected coordinate system (EPSG:2284), ensuring alignment with all enterprise gas-related mapping layers and regulatory datasets. All GIS layers and datasets are owned by the City of Richmond and cannot be modified, re-distributed, or re-sold without a sub-licensing agreement. All guarantees of validity expire once a dataset leaves the City of Richmond firewall or physical premises. Acknowledgement of the City of Richmond GIS would be appreciated in products derived from these data.
