Subject: Bioretention
Date: Tue, 08 Jan 2002 10:28:50 -0500
From: Linda Lewis <[e-mail]>
Organization: NC DENR
To: Ricky Revels <Ricky.Revel [e-mail]>
Dear Ricky:
I am faxing you a surface area and volume calculation for bioretention.
I use Schueler's method to determine the required volume. The provided
volume is found by multiplying the proposed basin length x width x
height, all in the same units, of course. For example, Basin 1 is
proposing a length of 150' and a width of 241. Since the maximum pond
depth is 611, or 0.5 feet, the provided volume is 150 x 24 x 0.5 = 1800
cubic feet. If the basin shape is irregular, you can use an average
length and width. I would take 3 or 4 measurements at equal intervals in
the basin and average them.
The 4' depth below the filter is not considered in the volume
calculation_ This is filled in with suitable planting soil, so there is
essentially no storage volume available here. You need only concern
youself with the amount of storage being provided within the 6" maximum
up top.
The drawdown time is found by dividing the provided storage volume (in
cubic feet) by the expected infiltration rate of the soils in cubic feet
per hour. Most infiltration rates are given in inches per hour, so all
you do to convert to cubic feet per hour is divide the inches per hour
by 12. For example, a rate of 8" per hour equates to 0.667 cubic feet
per hour.
As far as trees and shrubs go, the minimum is 1000 trees and shrubs per
acre of bioretention basin. These requirements are listed on page 53 of
the BMP manual. In your case, Bioretention area Number 1 is 150 x 24 =
3600 sq. ft., or .0826 acres_ This equates to a minimum of 83 trees and
shrubs. Your engineer specifies 102, so the total is OK. Of that 102
there should be 2 to 3 times as many shrubs as trees. For this project,
there should be anywhere from 68 to 77 shrubs. The engineer provides 77
shrubs, so that is OK, too.
I would not concern myself with the water balance calculations.
Hope this helps you. Linda

appropriate conditions for aquatic vegetation. This shelf should be sloped 6:1 or flatter and
extend to a depth of 2 feet below the surface of the permanent pool. A list of suitable
wetland species and propagation techniques are provided in Schueler (1987) and Maryland
DNR (1987).
12. Provide permanent pool dimensions.

14. Specify vegetation (grass) on 3:1 slopes (seed schedule) (SEC).
if a modification, have you considered the ramifications of the changes` For example, changing a
drainage area means revising the calculations, supplement form and application. Adding built -upon area
requires the same revisions. Make sure all the documentation matches up with the new information.

Dear Mr. Gatti:
This office sent you'a letter dated November 27, 2000 which required you to make an application for which
no response was received. A reviev of the stream classification for Carolina Court was previously reviewed and
determined to need a State Stormwatcr Management Permit for High Quality Waters.
In that your project is required to obtain a "State" stormwater permit, see attached a permit application
package consisting of - A Stormwater Management Permit Application, fee schedule, and supporting information.
Please be advised that you must complete and submit the attached application form (SWU-101) and all
necessary supplements (SWU 102-107). Please refer to the attached check list to make should you have
properly reviewed the requirements for a -complete application. if you choose the Low Density option a
Registered Land Surveyor's (RLS) seal will be required. But, if you choose the High Density option you must obtain
a Professional Enginccr(P.E.) scaled system.
Again please be advised that construction of "any" built -upon areas prior to receipt of a Storrnwatcr
Management Permit is a violation of North Carolina General Statues.
Please note that the information requested must be received within 30-days, or file will be closed for this
subjectprcject as a result of no response. Please reference the project number above on all correspondences. if

requires any project that is required to obtain an Erosion and Sedimentation Control Plan
approval, to apply- for a Stormwater Management Permit. In order to determine if a
Stormwater Management Permit will be required for this project, the classification of and
distance from the receiving waters must be verified by this Office. Please.return the attached
classification request form with a copy of that portion of the USGS quad sheet with the
project and the closest downsiope named receiving waters clearly noted.
A Stonnwater Management Permit Application, fee, and supporting information will
be required if this project is either draining to an Outstanding Resource Water or within i mile
of and draining to a High Quality Water. Projects that drain to Water Supply Watersheds must

Re: Approval of Soil Erosion and
Sediment Control Plan
Carolina Court
Moore County, North Carolina
Dear Mr. Gatti :
The review of the above -referenced erosion control plan has been completed.
The plan has been found to be acceptable subject to the following stipulations:
i . This project is located in a High Quality Water (HQW) Zone. All
requirements regarding sensitive area watersheds should be followed.
2. Enclosed is a Certificate of Plan Approval which must be displayed at the job
site. Title 15A, Section 413.0127(c) of the North Carolina Administrative Code
requires that no person may initiate a land -disturbing activity before notifying
this agency of the date the land -disturbing activity will begin. Failure to provide
notification will result in a violation of this plan approval.
3. In order to ensure the early coordination and implementation of the erosion
control plan for this project, it is requested that a preconstruction conference be
held. As a minimum, representatives of the owner, engineer, contractor, and this
office should attend, subject to the availability of staff. Please notify William
co ins of this office as to when this conference is scheduled. It is also
requested that you notify this office of the proposed starting date for this project.
4. Title 15, Section 4B.0017 (A) of the North Carolina Administrative Code
requires that a copy of the approved plan be on file at the job site and that
inspections of the project be made by this office to ensure compliance with the
approved plan.
5. Please note that this approval is based in part on the accuracy of the information
provided in the Financial Responsibility/Ownership Form which you provided.
You are required to file an amended form if there is any chang
information included on the form.

Re: Carolina Court

6. Acceptance and approval of this plan is conditioned upon your compliance with federal and
state water quality laws, regulations, and rules. In addition, local city or county ordinances or
rules may also apply to this land -disturbing activity. This does not supersede any other permit
or approval. The developer is responsible for obtaining any and all permits and approvals
necessary for the developing of this project prior to the commencement of this land -disturbing
activity. This could include the Division of Water Quality under storm water regulations, the
US Army Corps of Engineers under Article 404 jurisdiction, local county or town agencies
under their local ordinances, or others that may be required. This approval cannot supersede
any other permit or approval; however, in the case of a Cease and Desist Order from the Corps
•of Engineers, that Order would only apply to wetland areas. All other lands must still be in
compliance with the Sedimentation Pollution Control Act.
7. If any area on site falls under the jurisdiction of Section 404 of the Clean Water Act, the
developer is responsible to the orders of the US Army Corps of Engineers. Any erosion control
measures that fall within jurisdictional wetland area must be relocated to the transition point
between the wetlands and the highlands to assure that the migration of sediment will not occur.
If that relocation presents a problem or contradicts any requirements of the Corps of Engineers,
it is the responsibility of the developer to inform the Land Quality Section's Regional Office
so that an adequate contingency plan can be made to assure sufficient erosion control on -site.
Failure to do so will be considered a violation of this approval.
8. Any borrow material brought onto this site must be from a legally permitted mine site or other
approved source. A single.use borrow site is only permissible if all of the following apply: (1)
The excavation or grading is conducted to provide soil or other unconsolidated material to be
used without further processing for a single off -site construction project for which an erosion
control plan has been approved in accordance with Article 4 of Chapter I I3A of the NCGS.
(2) The affected land, including nonpublic access roads, does not exceed five acres. (3) The
excavation or grading is completed within one year. (4) the excavation or grading does not
involve blasting, the removal or material from rivers of streams, the disposal of off -site waste
on the affected land, or the surface disposal of groundwater beyond the affected land. (5) The
excavation or grading is not in violation of any local ordinance. (6) An erosion control plan for
the excavation or grading has been approved in accordance with Article 4 of Chapter 113A of
the NCGS.
9. Fallowing the completion of the project, you should notify this office to schedule a final
inspection. The purpose of this inspection is to ensure that all erosion control requirements
have been met.

Mr. Gatti
Re: Carolina Court
Page 3
10. This project is subject to the National Pollutant Discharge Elimination System (NPDES) and
covered by the enclosed general storm water permit NCGOlOOOO (Construction Activities).
You should become familiar with all of the requirements for compliance with the enclosed
general permit.
This approval is subject to the satisfactory performance of the erosion control measures under
held conditions. Should it be determined that the requirements of the Sedimentation Pollution Control
Act of 1973 (GS 113A, 51-66) are not being met, revisions to the plan and its implementation will be
required.
This permit allows for a land disturbance, as called for on the application plan, not to exceed
7.46 acres and/or the limits of the submitted plans. Exceeding these limits will be a violation of this
permit and would require a revised plan and additional application fee. Amendments to the plan should
be submitted to this office under the same procedures as followed for the original plan. This plan
approval shall expire three (3) years following the date of approval, if no land -disturbing activity has
been undertaken, as is required by Title 15A NCAC 4B .0029.
We look forward to working with you on this project.
Sincerely,
