Del-Mar, California

13 Land Tracts in San Diego County , San Diego Watershed

Del-Mar, California, located in San Diego County, faces relatively high hazard risks due to its proximity to fault lines and mountain peaks. The city lies within the Southern California Coastal hydrologic subregion, which is known for its susceptibility to earthquakes. The nearby San Diego hydrologic unit further increases the risk of seismic activity, as evidenced by historical events like the 1857 Fort Tejon earthquake that affected the region. Additionally, the Laguna-San Diego Coastal hydrologic accounting unit highlights the potential for flooding and landslides, especially during periods of heavy precipitation.

The coastal location of Del-Mar also exposes the city to risks associated with sea-level rise and storm surges. Climate factors such as high humidity and moderate temperatures contribute to the city's vulnerability to extreme weather events, including hurricanes and tropical storms. The area's coastline is susceptible to erosion, particularly in the face of rising sea levels, which can exacerbate the impact of natural disasters. The presence of water bodies like the Pacific Ocean further heightens the risk of flooding and coastal hazards.

Overall, Del-Mar's geological features, including fault lines, mountain peaks, and coastlines, significantly influence its hazard risk profile. The combination of seismic activity, flooding, and coastal vulnerabilities underscores the need for comprehensive disaster preparedness and mitigation strategies in the region. Stakeholders should prioritize measures to address these specific climate factors and geological risks to enhance the city's resilience to natural disasters.
