Re: Reply to the Division of Water Quality's Request for More Information Q
Booth Mountain p ~ ~( 3 2U06
Pittsboro, Chatham County, NC
To Whom It May Concern:
DENR -WATER QUALITY
WETLANDS AND STt?RMWATE.R BRANCH
The purpose of this letter is to respond to your Request for More Information letter dated
September 22, 2006. The original questions/requests are copied below as they appear within letter
and are then followed by our response.
Additional Information Requested:
i. Please provide documentation indicating how you determined whether onsite streams were
perennial or intermittent. This determination must be made by the DWQ.
The streams were evaluated onsite by S&EC staff utilizing the NCDWQ Stream
Classification Form and/or the USACE Stream Quality Assessment Worksheet.
However, because this determination must be made by the DWQ, a site visit has been
scheduled with Eric Kulz of the Raleigh Regional Office. This site visit is scheduled
for October i9, 2006. A summary of this site visit will be provided after October 19th
to verify our determinations.
2. Impact $ appears to be at a 60° - 6$° angle. Please redesign this crossing so that the impact
angle is between 75° and io5°. Also, this impact leads to `future development". Does this need
to be done right away, or can this impact be done when the `future development" begins?
Impact g has been redesigned to be more perpendicular, minimizing proposed
impacts to the stream, please see the revised Overall Site Plan, revised Location Map
2 & g and revised Impact Map-Crossing 3. The revised PCN Application is also
attached which includes the new proposed impacts for Impact g.
In addition, with regard to the "future development", this crossing does lead to
"future development" however it is a proposed impact well within the property
boundaries leading only to future residential development that will need to take place
in order for this project to be feasible. Furthermore, because this is a single &
complete project, it was our understanding that all known proposed impacts should
be applied for initially therefore avoiding any future undefined cumulative impacts.

3. Project imperviousness area listed a 2g.8%. However, calculations/figures are confusing. The
calculations attached with the PCN use a site area of 948 acres, but in Section VII of the PCN the
site is listed as 314 acres. Please reconcile this discrepancy. Also, the calculations list x,39 lots, but
I count i8o lots on the plans. Please reconcile this discrepancy as well.
The previously submitted impervious calculations were incorrect; these calculations
were for a different project and were inadvertently submitted. Attached are the
correct Maximum Potential Impervious Calculations with a total imperviousness of
zo.i%. This includes the correct total tract acreage and the correct total build out of
all lots. In addition, I have attached a revised PCN Application which includes the
correct property size in acres.
We anticipate that this answers all of the DWQ's questions in order to complete the final review
process fora 401 Water Quality Certification. If you have any further questions or any additional
explanation is needed, please don't hesitate to call.
Sincerely,
Lam' ~ ~ k~-- ~C~~~~~'"~_

III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
Page 3 of 9

Provide a written description of the proposed impacts: The proposed permanent impacts
include 94 linear feet of important/perennial stream, 206 linear feet of
unimportant/intermittent stream and 0.025 acre of jurisdictional wetlands for road crossings.
The proposed temporarypacts include 33 linear feet of important/perennial stream for the
construction of the Sanitary Sewer Force Main and a road crossing„ 10 linear feet of
unimportant/intermittent stream for a construction corridor of a road crossing_and 0.224 acres
of jurisdictional wetlands for the Sanitary Sewer Force Main crossing.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
