1 Great California Delta Trail Blueprint for Contra Costa and Solano Counties GIS AND MAPPING MEMORANDUM JULY 2010 {DRAFT} July 2010

3 Introduction Geographic Information Systems (GIS) are computer-based mapping and database programs that store, manage and analyze information tied to points, lines and areas on maps. Almost any type of information can be displayed and analyzed, making GIS mapping and analysis ideal for many regional planning efforts. For the Delta Trail, GIS maps and analysis are ideal to understand conditions, opportunities, and constraints, identify where trails exist or are already planned, and to study and plan new alignments. GIS for the Delta Trail Part of the background work for the Great California Delta Trail was to collect relevant GIS data for Contra Costa and Solano Counties and prepare preliminary maps of existing and previously planned trails, and preliminary concepts for new trails that may be included in the Delta Trail System. The GIS data is available for use by local agencies and organizations for more detailed trail planning work that may follow the Blueprint. It can be used to identify (for example): Baseline Conditions Primary and secondary Delta zones City and County boundaries and spheres of influence Demographics Land use, zoning, parks, waterways Existing transportation network Opportunities Existing and planned bicycle, pedestrian and trail systems Supportive land uses (parks, open space, commercial or residential development where trails might be an amenity) Public parcels and rights of way Utility corridors, levees and rail corridors where there may be physical space for a trail Constraints Conflicting land uses (agricultural, industrial, existing residential) Limited or unavailable right-of-way Major highway, road, or rail lines Flood zones, drainages, waterways (except for water trails) Sensitive/protected species and habitats GIS data is useful for studying trail routes, and can even be used for preliminary design, depending on how on the level of data detail. However, when resolving specific design, more detailed topographic and boundary surveying is typically required. Technical studies and plans are also required to address the environmental and physical constraints and respond to the needs of trail users, adjacent land owners/users, and the trail owning and managing agencies. Table 1 provides a list of GIS data that was collected for the project. Figures 1 and 2 provide maps of the counties, and an example of a more detailed route map (Figure 3) that could be used in subsequent stages of trail study and implementation.
