9. The 15” outlet pipe from CB-490 should be included in the HydroCAD model to ensure
the pipe does not restrict flow and back up water at the low point. The 19” horizontal
orifice should be routed to the 15” pipe.
10. The slope of the outlet pipe from Wetland 12 should be updated in the HydroCAD model
to match what is illustrated on the plans.
11. For the basins where filtration is proposed, the infiltration in P8 should be routed to the
downstream waterbody instead of out of the system for accuracy. It appears the proposed
stormwater system will still meet water quality requirements after the updates.

construction activities and remain installed until completion.
2. The applicant shall meet the minimum requirement of 461 trees for the development. All
