Project Name: Cedar Mountain Subdivision
REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
Dear Mr. Lewis:
On December 7, 2006, the Division of Water Quality (DWQ) received your application fora 401 Water
Quality Certification. The DWQ has determined that this information is incomplete. Please provide the
additional information requested below in order to prevent denial of your application as required by
15A NCAC 2H .0506:
1. Please provide full-size maps and site development plans as described in the PCN Addendum.
2. Stormwater Management: The impervious surface cover appears to have been calculated based on the
entire 162-acre site. This project appears to be a phased subdivision project and that the proposed
development depicted on the plans is considerably smaller than 162 acres. Please recalculate the
impervious surface area based on the area of the tract you are developing. DWQ does require
engineered stormwater management for pockets of high density even if the overall impervious surface
is below the threshold. Please also include a breakdown of any high-density areas (e.g., the northeast
corner of the site appears to be high density).
3. The average stream widths indicated on the PCN application appear to be unusually wide. Please
recheck average stream width as compared with culvert design to ensure adequate sizing.
4. There appears to be a discrepancy between the stream impact lengths on the PCN form, and the stream
impact detail sheets. Please include any proposed riprap at the inlets and outlets of the culverts in the
stream impact length and that the amount of impacts noted and/or depicted on the plans match the
amounts listed within the PCN application.
Please respond within five (5) days of the date of this letter by sending five (5) sets of this information in
writing.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters or
protected buffers.
