Alan W. Klimek, P.E. Director
Division of Water Quality
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Villas at Murrayville on September 27, 2006. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No. SW8 060717

This permit shall be effective from the date of issuance until October 26, 2016, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements in this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system will result in
future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within sixty (60) days
following receipt of this permit. This request must be in the form of a written petition,

Depending on how the permit was written, it is possible to utilize the future
development allowance in the permit to cover the increased building size under a
plan revision. If you want to go Express on the Plan Revision, be sure to schedule
it through Cameron.

Hi Linda,
I am in somewhat of a sticky situation and I am hoping you can help me. We
received a new building footprint from the architect just a couple of weeks ago,
and before I could get in touch with Paul Bartlett, the storm water permit was
issued for this site (10/26/06). in the meantime, our site layout changed, and
with it so did the amount of proposed impervious. We had originally proposed
14,374 SF of future impervious area, and our increase in impervious due to the
building layout change is only 8,132 SF of impervious. Since we are still under
the permitted amount of impervious, can we submit for a plan modification and
reallocate that area to reduce the future impervious from the 14,374 SF to 6,242
SF and then later submit for the full modification when the owner decides to
develop the future tract? Just let me know what you think.
Thanks!

Please note that this request for additional information is in response to a partial, preliminary
review. The requested information should be received by this Office prior to October 3, 2006,

Date/Time of Soils Investigation

Summary/Comments: f c,
I �
All proposed infiltration areas and existing, active utility lines located within the proposed basin/trench
must be marked and flagged. if these areas are not flagged, the Soils Scientist reserves the right to
decline to do the investigation. If the proposed infiltration system will be located in an area of existing
pavement and there is no open area nearby, equipment capable of breaking through the impervious
layer must be provided. The soils investigation does not take the place of a soils report prepared by
an appropriate professional. The Soils Scientist will only verify the soil conditions that are reported in
the Soils Report, and make a determination as to the suitability of the site to meet the infiltration
design requirements under NCAC 2H.1000, and assumes no liability should the system fail.
