Re: Request for Additional information - 40NVade
W&R Project #: 204467
DWQ Project #: 06-09.61
Dear Ms. Karoly,
~.
~.;, i
We received your request for additional information on June 20, 2006 regarding the 40/Wade Project. I
have included a brief response to each of your requests below. We have also provided the details for
the diffuse flow measures utilized on-site. Your letter asks for the following information:
1) Please indicate the diffuse flow provision measures on the site plan. Also include associated
worksheets and O and M agreements for your diffuse flow measures.
We have included the level spreader details and associated worksheets with the attachments.
Due to the slopes, we are providing two level spreaders in series to insure that the stormwater
enters the buffers afnnn-erosive velocity.
2) The pedestrian crossing labeled as 'F' on the plans does not appear to be necessary. Please
eliminate this crossing or provide additional information as to why it is necessary for this
project.
Below is the response provided by the project manager.
In order to comply with the Pedestrian circulation plan, as approved by the City of Raleigh, and in
an effort to facilitate more healthful living .through the encouragement of pedestrian connectivity
within the project, the proposed crossing has been identified as a requirement of the PDD Master
Plan for this project (see attached plan). In an effort to minimize disturbance to the riparian buffer,
the proposed crossing was located based on the findings of a tree survey performed by Monroe
Timberland Consultants. Specifically, the proposed crossing is sited within an area That does not
the City of Raleigh qualifications fora Tree Conservation Area. Additionally, the crossing is
intended to be afoot-bridge, which will avoid direct impacts to the stream itself and the clearing will
be limited to the minimum amount required for the installation of the pedestrian trail and foot-bridge.
3) Please provide a copy of the EEP acceptance letter.
The EEP acceptance letter is included with the attachments.
Please feel free to call if you have questions or require additional information.
Sincerely,

REQUEST FOR MORE INFORMATION ~~'
Dear Mr. Raul:
On June 12, 2006, the Division of Water Quality (DWQ) received your application dated June
12, 2006 to impact 0.032 acres of wetlands, 314 linear feet of streams, 37,904 square feet (ft2) of
Zone 1 protected riparian buffers and 26,470 square feet (ft2) of Zone 2 protected riparian buffers
to construct the proposed housing development and mixed use development. The DWQ has
determined that your application was incomplete and/or provided inaccurate information as
discussed below. The DWQ will require additional information in order to process your
application to impact protected wetlands and/or streams on the subject property. Therefore,
unless we receive the additional information requested below, we will have to move toward
denial of your application as required by 15A NCAC 2H .0506 and will place this project on
hold as incomplete until we receive this additional information. Please provide the following
information so that we may continue to review your project.
Additional Information Requested:
1. Plan Details
Please indicate the diffuse flow provision measures on the site plan. Also include
associated worksheets and operation and maintenance agreements for your diffuse flow
measures.
2. Impact Justification (Avoidance and Minimization)
The pedestrian crossing labeled as "F" on the plans does not appear to be necessary.
Please eliminate the pedestrian crossing or provide additional information as to why it is
necessary for this project.

Filter Strip/Buffer Vegetation thick grass/ground cover
(thick ground cover or grass, canopied forest with

Pre-Treatment or Bypass Method First Level Spreader at discharge elevation with second lust before Zone 1 of
Buffer
II. REQUIRED ITEMS CHECKLIST
Initial in the space provided to indicate the following design requirements have been met and supporting documentation is
attached. If a requirement has not been met, attach an explanation of why. At a minimum, a complete stormwater management
plan submittal includes a worksheet for each BMP, design calculations, plans and specifications showing all BMPs and outlet
structure details, a detailed drainage plan and a fully executed operation and maintenance agreement. An incomplete submittal
package will result in a request for additional information and will substantially delay final review and approval of the project.
Applicants Initials
Level spreader is at least 13 ft. per cfs for thick ground cover or grass or 100 ft per cfs in canopied forest
with leaf litter
Pre-Form Scour Holes are on flat slopes only
No structures are located in protected buffers*
If bypass method specified in the Draft Level Spreader Design Option Document:
Bypass method is specified (if applicable) and plan details and calculations are provided
Discharge to level spreader and subsequent filter strip is hydraulically and spatially separate from the
bypass discharge.
No structures are located in protected buffers.
Plan details for the bypass and outlets are provided.
The operation and maintenance agreement includes annual erosion and vegetation repair.
The operation and maintenance agreement signed and notarized by the responsible party is provided.

* Level spreaders in series can be used on slopes of up to 15% in forested areas with leaf littler cover or on slopes of up to
25% in areas with thick ground cover or grass if designed according to the Draft Level Spreader Design Option Document. This
potentially requires a minor variance in protected buffer areas. In any event the second level spreader cannot be located in
Zone 1 of a protected buffer area.

LEVEL SPREADER OPERATION AND MAINTENANCE AGREEMENT
The level spreader is defined as an elongated, level threshold, designed to diffuse stormwater runoff.
Maintenance activities shall be performed as follows:
1. After construction and until vegetation has been established, level spreader(s) shall be inspected
after every rainfall. Thereafter, level spreader(s) shall be inspected at least every month and more
frequently during the fall season and after heavy rainfall events:
a. Accumulated sediment, leaves, and trash shall be removed, and repairs made if required.
b. Inspect level spreader(s) for evidence of scour, undercutting, settlement of the structure,
and concentrated flows downhill from the level spreader(s).
c. .A level elevation shall be maintained across the entire flow-spreading structure at all
times. Repair or replace the level spreader if it is damaged.
d. Mow vegetative cover to a height of six (6) inches and prune plants if they cover over half
of theievel spreader surface.
e. Repair eroded areas and replace/replant dead or damaged vegetation.
2. The contractor should avoid the placement of any material on and prevent construction traffic
across the structure. If the measure is damaged by construction traffic, it shall be repaired
immediately.
3. Inspect and repair the collection system (e.g., catch basins, pipes, swales, riprap) four (4) times a
year to maintain proper functioning.
I acknowledge and agree by my signature below that I am responsible for the performance of the
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to
any changes to the system or responsible party.

The purpose of this letter is to notify you that the North Carolina Ecosystem Enhancement Program (NC EEP) is willing to
accept payment for impacts associated with the above referenced project. Please note that this decision does not assure that
the payment will be approved by the permit issuing agencies as mitigation for project impacts. It is the responsibility of the
applicant to contact these agencies to determine if payment to the NC EEP will be approved.
This acceptance is valid for six months from the date of this letter. If we have not received a copy of the issued 404
Permit/401 Certification within this time frame, this acceptance will expire. It is the applicant's responsibility to send
copies of the 404/401/CAMA permits to NC EEP. Once NC EEP receives a copy of the 404 Permit and/or the 401
Certification an invoice will be issued and payment must be made.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the
following table.
