Dear Mr. Baker:
The Wilmington Regional Office received a complete, modified Stormwater Management Permit Application for Rice
Creek Plantation — Phase I on August 6, 2010. 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 070333MOD, dated August 9, 2010, for the construction of the project, Rice Creek
Plantation — Phase I.
Please replace plan sheet C8 as well as the stormwater application, pond 8 supplemental form, pond 8 maintenance
agreement, and the curb outlet swale supplement of the existing approved plan set with the enclosed sheet C8,
stormwater application, pond 8 supplemental form, pond 8 maintenance agreement, and the curb outlet swale
supplement.
A copy of the recorded deed restrictions must be submitted to the Division within 30 days of the date of recording
the plat, and prior to selling lots. The recorded copy must contain all of the statements in section 1.23 of this
document, the signature of the Permittee, the deed book number and page, and the stamp/signature of the Register
of Deeds.
This permit shall be effective from the date of issuance until April 26, 2017, 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 thirty (30) days following receipt of this permit. This request must
be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed

IV. , 'PROJECT INFORMATION
1. 'In the space provided below, briefly summarize how the stormwater runoff will be treated.
Areas of high density will be treated with wet detention basins (Ponds 1-10 85% TSS) Remaining portions
of the project will be treated by 100' vegetated swales
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.Identify the regulation(s) the project has been designed in accordance with:
® Coastal SW -1995 ❑ Ph II - Post Construction
3. Stormwater runoff from this project drains to the Cape Fear River basin.
4. Total Property Area: 175.35 acres 5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: acres
7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area+:166.95 acres
+ Total project area shall be calculated to exclude thefollowing: the normal pool o impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHK) line or Mean High Water
(MHK9 line, and coastal wetlands landward from the NHW (or AIW line. The resultant project area is used to
calculate overall percent built upon area (BLIA). Non -coastal wetlands landward of the NHW (or MHM line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 35.11 %
9. How many drainage areas does the project have?11 (For high density, count 1 for each proposed engineered
stormwater BMP. For low density and other projects, use 1 for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

RICE CREEK PLANTATION - Phase I
Modification
PROJECT NARRATIVE
Rice Creek Plantation consists of a 1,306.37 acre tract located on US Hwy 17 (Ocean
Highway) in Brunswick County, NC. The developer proposes to construct roads, and install
sewer and water utilities to serve commercial office buildings, 361 multi -family units and
1,656 single-family homes.
Phase 1 of Rice Creek Plantation consists of multi -family Tracts H, I, L, single-family Tract
A and a portion of the Thoroughfare (as shown on the Rice Creek Plantation - Master Plan),
totaling 175.35 acres. The developer will disturb approximately 122.14 acres during
construction of Phase 1, which includes 361 multi -family units and 175 single-family homes.
The erosion control permit for Rice Creek Plantation- Phase 1 (Bruns 2007-396) includes
both Phase 1 and Town Creek Elementary School (21.21 acres of disturbance) for a total of
143.35 acres of disturbance.
Stormwater runoff from Tracts H, I and L will be directed to ten (10) on -site wet detention
basins. The developer proposes to install asphalt roads throughout the subdivision with 30"
standard or 24" roll curb and gutter, which will direct runoff to the stormwater collection
systems (Tracts H, I & L) or 100' vegetated swales (Tract A. and portions of the
Thoroughfare). As established on the Stormwater Master Plan, limits will be established for
all single-family lots, multi -family residential areas and commercial areas to the extent that
the project as a whole meets low density criteria at the 30% (non -SA waters) level. The
single-family lots within Tract A are limited to 3,000 SF of impervious surface.
This modification request is to remove a portion of the Thoroughfare from the collection
system that is directed to Pond 8, and provide 100' vegetative swale for this portion of the
Thoroughfare.
