Level Spreader Design - Requested Information
DWQ# 05-0588
Dear Ms. Edwards:
This letter is in response to the May 5, 2005 Request for More Information letter to Mr.
William Parrish regarding the referenced project. In your letter you noted the following
questions:
Question 1; Please indicate the diff use flow measures on the site plan and provide level
spreader worksheets. These can be found on our ivebsite.
Response:
In June 2005, Soil & Environmental Consultants, PA, was engaged by Williams-Pearce
and Associates, PA of Zebulon, NC, to perfonn the necessary level spreader design to
bring a series of three (3) storm water outfalls into compliance with the Division of Water
Quality's standards regarding diffuse flow through the buffer.
As per your previous discussion with Mr. Aaron Cooper, we have performed the
necessary calculation for each level spreader in accordance with the design criteria posted
on the Division's website.

August 12, 2005
Project No. 8433.W l
We have made the following assumptions regarding our proposed design:
1. Select design assumptions and site data provided by Williams-Pearce and
Associates, PA, regarding site impervious percentage, Rational coefficients,
site topography, sub-catchment drainage areas, etc., have been reviewed by
DWQ and are generally acceptable.
2. Roads will be designed, graded, and paved (by others) such that they drain to
the road side swales and cross-drainage pipes.
3. Level spreaders are required for the provision of diffuse flow at three specific
site locations where storm water from site roads and adjacent properties is
collected (and concentrated) in roadside swales and cross-drainage pipes.
4. The buffers as described on the digital plans are correct and appropriate for
use in our design setbacks.
The following notes are provided regarding our design of the level spreaders:
1. The conventional level spreader design (as described on DWQ's website) will
apply such that the entire discharge (10-year) will be passed through the level
spreader with no bypass.
2. All level spreaders and their filter strips will be constructed outside of the 50
foot buffer.
3. Ground cover (dense grass) will be provided through a combination of sod
mats and erosion control matting with temporary and permanent seeding
measures. Sod mats will be used within the level spreader (and its level
overflow lip) to immediately stabilize the level spreader and reduce the
potential for localized erosion, gullies, and rills. Between the level spreader
and the buffer, erosion control matting will be installed in conjunction with
permanent seeding measures to allow for a stabilized filter strip (of not less
than 50 feet) between the level spreader and the protected buffer.
4. Based on grass (sod and seeding) ground cover vegetation (in accordance with
the DWQ design guidelines) we have used a level spreader design length of
13 feet per one (1) efs of discharge (10-year design flow).
5. No individual level spreader has exceeded the 300 foot threshold. Level
spreaders have been located such that the slope from the level spreader to the
top of the stream bank does not exceed eight (8) percent.
6. Roadside ditches and swales (designed by others) as depicted on the plans will
be extended as required to allow for a hydraulic connection to the proposed
level spreaders as shown on the attached sheets.

Project No. 8433.W 1
As required we have completed a Division of Water Quality - Level Spreader Worksheet
to describe each of the three (3) level spreaders. We have also attached a spreadsheet
table which provides additional detail beyond that shown on the worksheets for further
clarification of our design process.
We have provided a site map to show general locations of the proposed level spreaders
(Sheet 1, 1" = 200' scale), depictions of each level spreader illustrating their appropriate
length and location, and typical cross-section and plan views of the proposed level
spreaders for your review. We recommend incorporation of these details by Williams-
Pearce and Associates into their site plans.
Question Ib: Please provide D1VQ buffer determination letter, other features are shown
on soil survey that have not been identified on your site plan.
Response:
Attached is the Buffer Determination Letter dated October 26, 2004.
Question 2. It is unclear why impact area #2 is not included in your stream impact table,
please explain.
Response:
The stream in question ends east of impact area #2 as indicated on the buffer
determination letter dated October 26, 2004.
Please review the enclosed documents and provide any comments or further questions at
your earliest opportunity. We thank you for your assistance to date and look forward to
the successful completion of this project. Please contact me if you have any questions or
comments.

Design Process:
1.) Determine drainage area for on-site, off-site and adjacent area (area immediately upslope of level spreader) which will contribute runoff to the spreader. Sum the areas.
2.) Determine the 10-Year discharge for the on-site, off-site and adjacent drainage areas. Sum the discharges. Round up to nearest CFS.
3.) Determine the slope of the filter strip based on available topographic data.
4.) Determine the length of level spreader per unit discharge required based on DWQ design guidance.
5.) Determine the length of level spreader required based on the product of the rounded discharge and the length of level spreader per unit discharge.

proj ect.
Additional Information Requested:
1. Plan Details
a. Please indicate the diffuse flow provision measures on the site plan and provide level
spreader worksheets. These can be found on our web site..
b. Please provide DWQ buffer determination letter, other features are shown on soil
survey that have not been identified on your site plan.
