WIND CLIMATE · EXPOSURE

Inland, seismic-governed design

Anaheim sits roughly 10-15 miles inland behind dense suburban terrain, so wind speeds stay low and earthquake loads typically govern. Wind still must be checked for permits.

85-95 mph basic wind

Risk Category II, 3-second gust per the ASCE 7-22 maps for inland Orange County.

LOW-WIND CLIMATE

Exposure B (suburban)

Continuous development with buildings, trees and obstructions covers virtually all of Anaheim.

SECTION 26.7

Seismic dominates

Newport-Inglewood, Whittier and San Andreas systems make earthquake loads the lead design driver.

COMPLIANCE CHECKLIST

What you need to comply

Six items that drive an approvable Anaheim wind submittal.

Correct wind speed

85-95 mph for Risk Cat II; higher for Risk Cat III & IV. Verify the locally adopted value.

3-SEC GUST

Exposure B

Use suburban Exposure B; do not apply Exposure C to inland Anaheim terrain.

TERRAIN

Current CBC edition

California updates Title 24 on a 3-year cycle and references ASCE 7-22 for wind.

TITLE 24

Components & cladding

Windows, doors, roof panels and wall cladding can be wind-critical even when MWFRS is seismic-governed.

C&C

Right Risk Category

Schools, assembly >300, stadiums and hospitals require elevated wind speeds per Table 1.5-1.

TABLE 1.5-1

California PE seal

Engineered and commercial designs need calcs sealed by a California-licensed PE for plan check.

PE-SEALED

Anaheim Hills note: eastern Anaheim at elevation may require topographic Kzt adjustments where escarpments or ridges apply. Official permitting runs through the City of Anaheim Planning & Building Department.
