Re: REQUEST FOR MORE INFORMATION, dated July 20, 2010
Dear Mr. McMillan:
Please find below responses to information requested in the letter dated July 20, 2010.
1. Please provide an agent authorization letter for the application signature.
The application was signed by the County Manager. The County Manager would be
the person who would sign an agent authorization letter.
2. Per the requirements of the Jordan Riparian Buffer Rule, all new stormwater conveyances
from this site must be discharged through a correctly designed level spreader or other
BMP that removes 30% of total nitrogen and total phosphorus. Because the bioretention
area is being used in lieu of a level spreader, the DWQ considers this device to be the
diffuse flow plan for new stormwater outlets A and B.
Discharges from stormwater outlets A and B represent treatment volumes for all
new impervious areas. Stormwater drainage patterns were altered from pre-
construction patterns so that existing outlets EA and EH received the same or less
flow. Therefore the diffuse flow plan would be to discharge existing outlets EA and
EH the same as pre-construction discharges and to discharge outlets A and B
through the proposed bioretention basin.

Email: [e-mail]
3. Please provide a full-size plan sheet showing the entire site with its storm drainage
system, including every inlet, outlet and conveyance device. Please show how diffuse
flow requirements have been met at each proposed new stormwater outlet location.
Sheet C400 shows the entire site with its storm drainage system, including every
inlet, outlet and conveyance device. Outlets EA and EH are existing outlets and the
flow to these outlets is equal to or less than pre-construction flows. Outlets A and B
are discharged through a BMP that removes 30% of total nitrogen and total
phosphorus.
4. Please address the following design issues with the bioretention area. Additional design
issues may become apparent after the DWQ has the opportunity to review the supplement
form and required items:
• The forebays of the proposed bioretention areas should be equipped with liners to
prevent stormwater from seeping through the berm and passing directly to the
underdrain system without appropriate treatment. Please provide a design for the
northeastern forebay.
The southern forbay is separated from the bioretention cell by 15' at the base,
and the bottom of the forebay is 1.3' above the stone and underdrain layer. Any
stormwater migrating through the forebay berm will enter the soil media of the
bioretention cell. The berm should be undisturbed clayey soils with relatively
low permeability. Therefore, it should not be necessary for a liner to prevent
stormwater from seeping through the berm and passing directly to the
underdrain system without appropriate treatment. NCSU has requested that the
forbay a planted. A liner would make it difficult for the plantings to establish
and result in a denuded forebay area. There is no northeastern forebay. There is
an area on the plans noted as future forebay. This area is only to show where an
additional forebay would go if needed in the event the northern portion of the
property is developed in the future. This future forebay would require design
and permitting at the time of the future development. A section of the future
forebay area has been added to sheet C401 to ensure that 3' of soil media is not
placed at this location.
The planting plan must show the actual location of the plants within the bioretention
cell.
The bioretention Planting Plan (sheet C601) has been completed to show the
locations of plants within the bioretention cell.
• The use of two-year, slow release fertilizer is in excess of the BMP manual's
fertilizer limitations, which allow only a one-time fertilizer application to establish
vegetation.
Fertilizer application within the bioretention cell has been eliminated. See note
4. General Planting Specifications on sheet C601.
• A scaled cross-section must be provided showing the forebay, treatment area,
underdrains, media, outlet structure, sand layer, mulch, filter fabric, etc.
The Cross section on sheet C401 has been revised to show the forebay, treatment
area, underdrains, media, outlet structure, sand layer, mulch, filter fabric, etc.
• The tree and shrub planting details should be modified to show one-half to one-third
of the rootball above grade.
The planting specifications on sheet C601 have been replaced with specifications
provided by NCSU. These specifications more accurately reflect the details on
sheet 600.
• The discharge pipe should be extended to the stream bank to avoid erosion issues
within the riparian buffer.
The bioretention discharge pipe has been extended to the stream bank.
A soil test to document the estimated elevation of the seasonal high water table must
be provided.
Chatham County public works department by way of a test pit has determined
that the estimated elevation of the seasonal high water table at the center of the
bioretention basin is 8' below the existing ground elevation or elevation 362.
This would be 2 feet below the bottom of the stone and underdrain system.
• The engineered soil media must have a minimum depth of three feet. The
appropriate P-index for the soil media must be specified.
The engineered soil media must has been revised to a minimum depth of three
feet. The appropriate P-index for the soil media has be specified. (see sheet
C401)
• A signed and notarized Operation and Maintenance Agreement must be provided.
Chatham County will be mailing the signed and notarized Operation and
Maintenance Agreement under separate cover.
5. Please explain how the remaining undeveloped area on the north side of the property
fronting US-64 will be utilized.
There are no current plans to develop the remaining area on the north side of the
property fronting US-64. The bioretention basin was oversized and an area
designated for a forebay to account for any future development of this area. The
proposed bioretention cell is sized for this additional impervious area so that in the
future ]IF an undetermined development were to take place the bioretention cell
would not have to be altered other than the design of inlet structures and a forebay.
Feel free to call me if you have any additional comments, need clarifications, or have
questions.
Sincerely,
