29 Is candidate site selected downwind of target road 

segment?

30 Are wind roses included to show predominant wind 

patterns?

Yes, figure C-6

31 Are physical attributes (roadway design, roadside 

structures, or terrain) desirable? (see Table 4-2 of Nearroad NO2

 TAD)

Yes, discussed in Appendix C, Physical 

Consideration

32 If applicable, was population exposure considered as an 

additional factor?

Relatively minor, see Appendix C under 

Location

33 Will this be a multi-pollutant site? If so, list additional 

parameters planned.

Yes, Table 2-1

34 Is proposed site in a “unique” location? (See Near-road 

NO2 TAD section 13.2)
