1. GIS Support For Water Resource Management in the Tecate, California and Tecate, Baja California Section of the United States – Mexico Border

2. Overall Project Goal ► To Assist Stakeholders in Managing Scarce Water Resources in the Ambos Tecates section of the border region ► Goal will be accomplished through the development of a water-focused GIS database and web-based tools

3. U.S. – Mexico Border

4. Urban Pairs in the U.S.-Mexico Border Region

5. Tijuana River Watershed

6. Ambos Tecates in the Tijuana River Watershed

7. Ambos Tecates Project Area Population: Tecate, MX – 78,000 in 2000 Tecate, US – >200 (2,000 in larger area) Border Crossings: 2.7 Million in 2002 57 Million in S.D. – B.C. (only 5% of S.D. – B.C total)

8. Ambos Tecates

9. ► An inadequate GIS infrastructure for supporting government decision-making is a characteristic shared by most urban pairs along the United States – Mexico border

10. Relation to Recent Existing Projects/Programs ► Tijuana River Watershed Binational Vision ► Tres Californias ► Integrated U.S.-Mexico Geographic Information System for Transboundary Watershed Management ► Identification and Mapping of Potential Ground Water Contamination Sources in Urban Tecate, Mexico

11. Tijuana River Watershed Bi-national Vision ► Purpose To develop a bi-national vision for the Tijuana River Watershed and devise strategies and options for achieving the vision based on stakeholder participation ► Origins  Tijuana River Watershed GIS, 1994-2000  San Diego-Tijuana International Border Planning Atlas, 2000  Tijuana River Watershed Atlas, 2005

12. Integrated U.S.– Mexico Geographic Information System for Trans-boundary Watershed Management ► Purpose To develop and implement a strategy for a bi- national water resources GIS in the U.S.-Mexico border region ► Project is led by Chris Brown, Jean Parcher, and Fabian Lozano ► The Ambos Tecates project is one of the pilot projects of this program

13. Tres Californias ► Purpose To increase university and stakeholder cooperation, technology transfer, and the enhancement of local and regional planning ► Anticipated Results Collection of new data, increased access to existing data, improved ability to create maps, and better tools to analyze spatial and tabular data ► Geographic Focus Two southernmost counties of California, Baja California, and Baja California Sur ► Targeted Users State and municipal government planners and decision makers ► University Partners  San Diego State University  The Autonomous University of Baja California, Ensenada  The Autonomous University of Baja California Sur

14. Identification and Mapping of Potential Ground Water Contamination Sources in Urban Tecate, Mexico ► Purposes  To create a GIS data storage and analysis tool for water resources in Tecate, Baja California, Mexico  Inventory Possible groundwater contamination sources  Provide GIS training to employees of the State Commission in Tecate and the Tecate Municipal Planning Department

15. Modeling Flood Risk

16. Flood Risk Evaluation Model FRI = HI + VI HI = Sli + Sti(0.5) + Gi and VI = Lui Vi = Vulnerability index Lui = Land use index FRI = Flood Risk Index Hi = Hazzard index Sli = Slope index Sti = Stream index Gi = Geomorphology index
