Ian please provide an appropriate comment on th°?retaming waAn Zone 2 of
the buffer (see DA-1 in the submittal received 12/17). I am not sure if it is a
definite "NO" or if they have to prove A&M. If you are going to allow thWsle -
retaining wall then those steep slopes just to the west of the retaining wall are a
NO-NO. Can you write some bullets to that effect? I should be home Wed if
you need to call me.
Based on Sheet DA-1 provided in the submittal received in the DWQ 401 Unit's
office on December 17, 2009 (dated December 16, 2009), it does not appear that
Swales 2 and 3 or the pipe discharging to EW2 are directing flow to an existing
swale. Per the requirements of the Neuse Riparian Buffer Rule, all stormwater
drainage from this site must be discharged through a correctly designed level
spreader. Level spreader design requirements are set forth in Chapter 8 of the
North Carolina Stormwater BMP Manual, available at:
http://h2o.enr.state. nc.u5lsu/bmp forms.htrn
3. Please provide one Level Spreader Supplement Form for each proposed level
spreader, available at: http://h2o.cnr.state.nc.us/sulbm forms.ht7n. Please
include the Required Items checklist and all items listed therein.
