My project is using Option 1: Design stroms,Case 2 :Site with existing imperviousness mote than 50%

LEED online template V 5.0 Table 6.1-3 Site runoff: Two year,24 hour Design storm quantity is requested to fill in cf/storm

Just wish to re-confirm that the cf/storm stand for cubic feet per storm?

Civil engineer had provided me a value in cubic meter 8900m3 per storm.

Am I correct to fill that in form as 314300 cf/storm (using 1 cubic foot = 0.02831685 cubic meter)

Thank you
