of the County ' s GIS . Personnel expressed a need for the creation of additional GIS data <br /> layers for use in mapping and spatial analysis in support of departmental objectives . <br /> Department personnel expressed that access to the following GIS data layers would be <br /> beneficial : <br /> • Boat ramps <br /> • Electrical Lines/Cables <br /> Irrigation Lines and Shut-off Valves <br /> • Pavilions <br /> • Permitting Information <br /> • Property Lines <br /> • Water Lines <br /> Please see the GIS data layers list provided below for a complete listing of all GIS layers the <br /> Parks Maintenance Division would find beneficial . Additional layers may be required as the <br /> facility increases its GIS utilization and incorporates additional data . <br /> Road and Bridge Division <br /> Road and Bridge Division personnel will need access to accurate and complete GIS data in <br /> order to fully take advantage of the mapping and analysis capabilities of GIS . In addition , <br /> personnel will need to work closely in a cross-functional capacity with other County <br /> departments ; the Division ' s responsibilities and services are complementary to the objectives <br /> of other departments . The Division ' s objectives require comprehensive access to various <br /> types of spatial data , including planimetrics , utility and transportation infrastructure , and <br /> environmental data . <br /> Three GIS needs for the Road and Bridge Division have been included in the General Public <br /> Works Department GIS Needs and Duties Section , including : <br /> • Geo-Spatial Data Creation and Integration <br /> • Field Access to Geo-Spatial Data <br /> • Mapping and Spatial Analysis of Bridge , Facilities and Infrastructure Data <br /> Storm Water Division <br /> The following have been identified as key GIS needs for the Storm Water Division : <br /> • Utility Geodatabase Geometric Network for Storm Water System <br /> • Storm Water Modeling <br /> Other needs for this Division have been included in the General Public Works Department <br /> GIS Needs and Duties Section , including : <br /> Mapping and Spatial Analysis of Facilities , Road , Bridge , and Infrastructure Data <br /> • Geo-Spatial Data Layer Creation <br /> It Utility Geodatabase Geometric Network for Storm Water System <br /> ESRI , in conjunction with many public and private utility organizations , has developed data <br /> models for water and sanitary sewer, and storm water distribution networks . These data <br /> models are designed to create a logical template for the creation of water, sanitary sewer <br /> and storm water ArcGIS geodatabases . The advantages of utilizing these data models <br /> include : <br /> • Utility business logic : rules for how utilities can and do interact <br /> • Standardized template of utility features , feature attributes, and relationships ( fully <br /> -- customizable , however) <br /> • Utility specific symbology <br /> 87 <br /> GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment <br />
