Santiago Canyon / Silverado / Modjeska Canyon

Rural, Hillside & Estate Land Development in Santiago Canyon, Silverado & Modjeska Canyon 

Orange County is currently updating its hazard mitigation plan, with the Silverado area specifically included in a 2026 community workshop addressing natural hazards including wildfire and flooding.  

Why Land Development Is Different Here 

These canyon communities should be positioned around hillside terrain, rural properties, access, drainage, erosion and wildfire considerations.

Property Types

Primary

  • Rural estates  
  • Equestrian properties

Common Problems Customers Face: 

1. Hillside erosion

Stormwater can rapidly move soil on slopes.

2. Drainage

Canyon properties can experience concentrated water flow.

3. Private road damage

Heavy rainfall can damage unpaved or lightly surfaced access roads.

4. Wildfire exposure

Vegetation management and defensible space are important considerations.

5. Difficult access

Terrain can make construction and emergency access more challenging.

6. Land clearing

Brush and vegetation can limit property use.

7. Slope stabilization

Land may require careful grading and stabilization.

8. Property restoration

Storm events, erosion or neglected land can leave properties needing re-contouring and cleanup.
