The following is a summary of the modifications that we are requesting to the originally
approved permit.
The project has been resubmitted and approved by the City of Raleigh do to the re-
phasing of the project. The city has requested a few changes to the SMP to ensure that
each phase met all the requirements and would stand independently. The BMP locations
have not changed but the originally approved dry ponds have been converted to wet
ponds. The area we are requesting modification now has a stormwater wetland followed
by a wet pond. Attached is a copy of the configuration. The City of Raleigh Forestry
Specialist as asked that we remove the level spreader or at least the grading in zone 2
as it was approved to keep it undisturbed and maintained as a tree conservation area.
We would like to modify the plan by removing the level spreader and vegetated filter strip
with the temporary grading in Zone 2 that was needed at the time it was approved. The
constructed wetland and wet pond BMP's have a total drainage area of 34.08 ac.
(1,484,317 sf) and 4 total inlets. Three of the inlets flow into the stormwater wetland
consisting of 32.66 ac (1,422,517 sf) of the total drainage area which then flows into the
wet pond. One inlet flows to the wet pond with a drainage area of 1.42 ac. (61,800 sf).
The treatment per cent is 40% for the storm water wetland and 25% for the wet pond.
The total Percent N reduction is calculated below.
Percent N for 32.66 ac.= (40+20)- (40x25/100)= 55%
Percent N for 1.42 ac.= 25%
The total N reduction for 34.08 ac.= (55 x 32.66 + 25 x 1.42)/ 34.08= 53%
We would like to request that since 53% N reduction is achieved above the 30%
required that we be allowed to discharge directly to the stream rather than through a
Level Spreader and Vegetated Filter Strip.
If you have any questions please call me at [phone].
Sincerely,
BrrHaertli ng
