  3.3.3  RRv Performance Summary

  A summary of the RRv provided is presented in the following table:

  Table 7: RRv Summary
  RRv Provided  % RRv Provided/
  WQv Required (CF)
  WQv Reduced (CF)  WQv Reduced
  8,672  1,337  >100%

  As indicated in the above table, the RRv provided is greater than the RRv required for the project site.
  As such, the RRv criteria has been met and the designer can proceed to Step 6.

  3.4 STEP 4 – Calculate the Minimum RRv Required

  As indicated above, Section 9.2.1.B of the Design Manual indicates, “Although encouraged, meeting
  the RRv criteria is not required for the redevelopment activity portion of a project.”

  3.5 STEP 5 – Apply Standard SMPs to Address Remaining Water Quality Volume

  If the entire Water Quality Volume is not treated through implementation of RR techniques and
  standard SMPs with RRv capacity, then the design must achieve the remaining WQv through the
  standard SMPs listed in Table 3.3 of the Design Manual or the Alternative Practices outlined in Section
  9.4 of the Design Manual.
