Solid Waste Authority of Palm Beach County/Utilities ArcGIS geodatabase design

This is the ArcGIS database design specification resulting from the Solid Waste Authority of Palm Beach County's Utilities Enterprise GIS Design and Development Project.

Overview
The source of most GIS features is the SWA Atlas maintained in AutoCAD format. For purposes of this design, G&O concentrated on utility assets and related features that support identified business priorities. These features include:


 * Landfill site - cell boundaries, wellfield zones
 * Leachate collection system - manholes, meters, valves, pumps, lines, clean outs and associated
 * Gas collection system - wells, meters, valves, lines and associated

Along with the utilities content, the Atlas drawing has 296 layers. As described in Maintaining the Utilities Database, these Atlas drawing layers will be transformed into GIS features for reference purposes. However, aside from ensuring correct spatial placement and assignment to proper feature types, they will be subjected to minimal post-processing.

Two additional features: 1) utility incidents and 2) construction project boundaries were identified as important geodatabase additions. The utility incidents point feature records locations where utilities are damaged. It is designed to connect to records in SWA's Incident materials release database. The construction project boundaries polygon feature will provide a way to associate utility construction activities with associated documents (e.g.; engineering drawings, permits, contracts, etc.).

The design, where appropriate, provides "hooks" to enable links between the utility GIS layers and other SWA systems, including the permits database, trouble ticket and SCADA systems. Hooks common across all features enable links to other network-enabled resources, including: digital photos, metadata, manufacturers, equipment part specifications and so on.

Features
The utilities geodatabase design is influenced by those of federal agencies that monitor and maintain landfills (i.e.; EPA, US Army), Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE) Environmental Hazards Solid Waste and HazMat standard and prior G&O projects.



Data Dictionary
Feature definitions, including properties, types, keys, indexes and similar are described in the Data Dictionary.

Datum
The Atlas graphic features are stored in the NAD27 datum. When transforming layers to the ArcGIS database, G&O will project these coordinates into NAD83.

Coordinate System
Feature coordinates recorded in Florida East Zone: UTM zone: 17, FIPS zone: 0901 ADS zone: 3601

Topology/Rules
Topology rules will be applied to the Geodatabase after the review process is complete. Please refer to the ESRI online help document Topology Rules for general information.
