California Conditions That Matter for Accessible Units

Across the 544 California places listed here (NOAA 1991–2020 normals by nearest station, Census TIGER coastline):

• 6 of 544 listed places are in the wet band for rain
• 1 of 60 places with snowfall data average 20+ inches of snow
• 58 of 544 listed places are within 5 km of a shoreline (TIGER)

The 5% rule is federal and applies the same way in every listed place; the ground under the route is what changes from city to city.

Range Across the State

Across the 544 listed California places with this figure (NOAA 1991–2020 normals), the low end is about 2 inches of precipitation a year (El Centro, Calexico and 5 other listed places) and the high end about 62 (Grass Valley, Alta Sierra and 1 other listed place); the middle place is near 13.

By Climate Region

By DOE Building America climate region (county level, PNNL guide), the planning focus shifts: Hot-Dry (382 places): firm routes instead of loose sand or gravel; Marine (145 places): routes that stay firm through long damp seasons; Mixed-Dry (10 places): firm routes and ramps clear of ice; Cold (7 places): routes and ramps cleared of snow and ice.

How Many Accessible Units

At least 5% of the units in each cluster must be accessible, rounded up (U.S. Access Board guide to the ADA Standards):

Worked example: the PSAI chart gives 38 units for 5,000 people over six hours. In one cluster, 5% of 38 is 1.9, so 2 accessible units; split into two clusters of 19, each needs 1, so 2; split into three clusters of 13, 13 and 12, each needs 1, so 3. Spreading units out can raise the count.

What to Ask For

• How many units are in each cluster (at least 5% accessible, rounded up)
• A firm, level, accessible route to the door
• Ramps for any level change
• Placement next to the main restroom row
