Tennessee Conditions That Matter for Accessible Units

Across the 114 Tennessee places listed here (NOAA 1991–2020 normals by nearest station, Census TIGER coastline):

• 104 of 114 listed places are in the wet band for rain
• None of the 27 places with snowfall data average 20+ inches of snow
• None of the 114 listed places are within 5 km of a shoreline (TIGER)

Heavy rain is common in most of the state, so build accessible routes on pavement or compacted gravel rather than grass.

Range Across the State

Across the 114 listed Tennessee places with this figure (NOAA 1991–2020 normals), the low end is about 43 inches of precipitation a year (Covington) and the high end about 61 (Tullahoma, Manchester and 2 other listed places); the middle place is near 54.

By Climate Region

All listed Tennessee places with a climate-region assignment fall in one DOE Building America region, Mixed-Humid (114 places): routes that stay firm after rain and clear of ice in winter.

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
