Description: This GIS point dataset contains street intersections across the City of Houston. Attributes include city service information, jurisdictional boundaries, FEMA flood zones, Census tract data, and a Google PlusCode field for enhanced location referencing. Warning: This layer does not contain a permanent unique ID. Do not use any existing field as a unique identifier or assume that future releases will retain the same values. The Google PlusCode field is unique within this layer; however, it is not permanent. If an intersection shifts even slightly, its PlusCode value will change. Source data includes the Planning & Development Department’s RoadCenterline layer, GIS datasets from the COHGIS geodatabase, and select public datasets. Developed in 2012 for address verification in the Lagan 311 system, the dataset now contains over 50 attribute fields. This layer is updated annually, with the most recent update completed on October 8, 2026.
