Working in Sun Valley

Sun Valley is a resort city in Blaine County immediately east of Ketchum, built around the Sun Valley Resort and the Dollar Mountain and Trail Creek corridors. The city's land area is dominated by resort, lodging, and hillside residential uses, with more than 80 percent of its boundary adjacent to wildfire-prone terrain — which makes wildfire resilience and design review the dominant regulatory themes rather than the urban-density concerns that drive nearby Ketchum.

• Planning & Zoning: City of Sun Valley Community Development Department, 81 Elkhorn Road, Sun Valley, ID 83353 — (208) 622-4438, [email protected]. Community Development page.
• Comp Plan: Sun Valley 2015 Comprehensive Plan Update, adopted September 10, 2015 (amended 2017). Plan PDF.
• Engineering Considerations:
  • Wildfire WUI: Sun Valley sits in a wildfire WUI (Wildland-Urban Interface) area with more than 80% of the city boundary adjacent to wildfire-prone land; the city has adopted fire-resistant roofing standards, established a 150-foot vegetation buffer adjacent to certain subdivisions, and is actively tuning defensible-space and firewise construction amendments. Idaho Firewise guidance applies.
  • Sun Valley design review: Development is subject to administrative and full design review processes through Community Development; resort-district, hillside, and visible-corridor sites should expect substantive massing, siting, and materials review in addition to zoning compliance.
  • Utilities — Sun Valley Water & Sewer District: Municipal water and sewer service is provided by the Sun Valley Water & Sewer District (an independent special district, not the city) rather than a city utility; new connections, capacity confirmations, and service extensions route through SVWSD in parallel with city land-use review.
