RE: DWR # 2019-1445v3
Response to 8/10/22 Request for Additional Information
Serenity Development
Harnett County, North Carolina
Dear Mr. Wojoski;
On behalf of Greenfield Communities, and Withers & Ravenel, please see below and the
attached information in response to your August 10, 2022 Request for Additional Information for
the above referenced project. As discussed with Sue Homewood on August 29, 2022, there are
several items that will require additional time to analyze. These are noted in the responses below
and will be provided by September 30, 2022. Each individual comment received is in italics
below, along with corresponding response.
1. If the USAGE requests a response to any comments received as a result of the Public
Notice, please provide the Division with a copy of your response to the USAGE.
We will provide the Division comment responses that are submitted to the USACE. Note
that this will include the Division's comments to the USACE, which will be addressed by
9/30/22.
2. Please provide an analysis of potential secondary and cumulative impacts as a result of
this development pursuant to the Division's Cumulative Impact Policy.
Please see the attached analysis and associated figure. It is our professional opinion,
based on the Division's Cumulative Impact Policy, that this project is not likely to
contribute to secondary and cumulative impacts in the project vicinity.
3. In order to ensure that the project is appropriately authorized, the Division requires
documentation that the USAGE has verified that wetland 23 is Isolated.
Understood. As noted in the application, we are not proposing this area as isolated due to
schedule constraints, but will confirm with the USACE if an Approved JD is achievable
in the permitting period. We will confirm this by 9/30/22.
4. While the Division recognizes that impacts to wetland 24 were inadvertent, as clearly
stated in the application, significant design effort was made to avoid this feature in
previous submittal. Pursuant to 15A NCAC 02H.01305(b) "In assessing whether the
proposed activity will comply with water quality standards, the Division shall evaluate if

Mr. Paul Wojoski
September 9, 2022
the proposed activity: (1) has avoided and minimized impacts to surface waters and
wetlands... ". Please provide further evidence that the current proposal meets this
criteria when prior design indicates this area could be avoided.
Page 2 of 4
We appreciate the acknowledgement that the impact was inadvertent and understand
additional justification is required. It should be noted that the avoidance of this wetland
in the prior Nationwide Permit submittal was done using preliminary design, and
impacting this wetland feature would have prevented the use of a Nationwide Permit for
the prior phase. The design has been advanced and while the retaining walls are not
completely impractical to build, they would result in redirecting approximately 94% of
the existing surface water drainage away from this wetland feature. After considering the
Division's concern for drainage of stream and wetland features (Item 10), it is likely that
a loss of wetland function could result at this location. Also, as the design has advanced,
retaining walls surrounding wetland 24 will average 15' in height from the original
wetland elevation. Given that there will be both some shading effect from the walls, and a
significant reduction in hydrology at this wetland, the construction of the walls (with an
associated cost of approximately $270,000) would still likely result in a loss of wetland
function regardless of the prior disturbance. With this evaluation, it is our request to
permit the wetland impact as proposed in the application.
5. Please provide a stream restoration detail and wetland restoration details for all
proposed temporary impact areas.
Details on temporary impacts have been added to the attached Impact Map set. Sewer
crossing temporary impact area details will be provided after coordinating with the local
utility authorities on their requirements. This information will be provided by 9/30/22.
Note that areas denoted as temporary wetland impact adjacent to riprap inlet/outlet
construction areas do not have a detail. These areas are denoted as temporary impact for
access only and the contractor will be required to use matts to prevent permanent
disturbance to those areas. Upon completion of the work, the areas will be inspected, and
if any compression of soils has occurred discing and reseeding with a natural wetland
seed mix will be performed. This information will be added to construction drawings as
the final plans for each phase are developed.
6. In order for the Division to adequately evaluate potential impacts to stream and wetland
functions, please provide detailed plans and profiles for all proposed culverts. These
details should include temporary dewatering details and riprap apron design details,
proposed culvert slopes, culvert burial (if appropriate) and stream width and culvert
diameters.
The requested information has been added to each culvert location in the attached Impact
Map set.
7. For all locations where multiple culverts are proposed, the plan sheets must clearly
detail that low flows shall be accomplished in one culvert/pipe and additional

Mr. Paul Wojoski Page 3 of 4
September 9, 2022
culverts/pipes shall be installed such that they receive only flows above bankfull. Please
provide design details that clearly show floodplain bench construction and/or sills at the
inlet and outlet of the culverts to ensure that the stream is not over -widened on either end
of the culvert. Please also provide a profile view of all stormflow culverts.
This information has been added to the attached Impact Map set for the multiple barrel
culvert at impact location S15.
8. The alignment of the culvert outlet at stream impact S17 appears to be directed at a
streambank. Please either provide a revised alignment or provide more detailed
information to clarify or otherwise address the proposed alignment.
The stream at impact S17 is relatively low flow as it originates just upstream of the
culvert inlet. The proposed slope of the pipe in the original submittal could result in some
stream bank erosion, therefore, an inside drop junction box has been added to allow the
outlet pipe to be constructed at a low grade with less slope, thus reducing the velocity and
potential for streambank erosion at the outlet. Based on engineering calculations for the
revised pipe grade, the proposed riprap stabilization at the outlet would adequately
control the discharge and minimizes impacts compared with rerouting the stream or
extending the pipe further downstream to the next bend which would entail additional
wetland impacts.
9. The riprap apron proposed at Impact S15 is extensive. Please provide plan and profile
construction details for the riprap outlet apron. The details should clearly show how
natural stream flow and conditions will be maintained within a low flow channel within
the enhanced riprap apron. It is the Division's experience that when excessively wide
riprap aprons are required for velocity control and/or stability that natural stream
function is not maintained and therefore these impacts should be considered as
permanent loss of stream.
The riprap apron at the S15 culvert outlet has been re-evaluated and reduced in size.
Culvert details have been added in the attached Impact Map set and provide the requested
information.
10. Pursuant to 15A NCAC 02H.0506(b) "a 401 Water Quality Certification may only be
issued upon determining that the proposed activity will comply with state water quality
standards which includes designated uses, numeric criteria, narrative criteria and the
state's antidegradation policy, as defined in rules of 15A NCAC 02B.0200... In assessing
whether the proposed activity will comply with water quality standards, the Division
shall evaluate if the proposed activity: (2) would cause or contribute to a violation of
water quality standards; (3) would result in secondary and cumulative impacts that cause
or contribute to, or will cause or contribute to, a violation of water quality standards".
In order for the Division to fully evaluate the potential hydrological impacts on some
stream and wetland features within the project limits, please provide the location of all
outlet structures from the SCMs shown on the proposed plan sheet. In order to avoid

Mr. Paul Wojoski Page 4 of 4
September 9, 2022
further requests for additional information upon receipt of the response to this item, the
Division strongly encourages that you carefully evaluate the proposed site plan for
locations where existing surface hydrology will be redirected which would have the
potential to remove or reduce the existing functions of a stream and/or wetland. Based on
the current proposed plan the Division believes there is potential for indirect impacts to
some features within the overall project limits.
The SCM outlets have been added as Sheet Q in the attached Impact Map set. The
engineering team is evaluating these outlets for pre- and post -construction drainage areas
and we will provide more detailed evaluation of each SCM by 9/30/22.
11. Please provide a conceptual construction schedule for all impacts proposed within the
application. Please note that mitigation will be required for ALL impacts unless a
mitigation schedule is requested, reviewed and approved by the Division. Please note
that any 401 issued by the Division will expire upon expiration of the 404 permit.
Noted. The anticipated construction schedule is represented on the attached phasing and
construction exhibit. Greenfield has elected to pursue phasing of the mitigation as
construction advances. We will coordinate this request with you and the USACE and
provide a detailed phased mitigation proposal by 9/30/22.
Please contact me at your convenience if you have any questions or require further information.
Sincerely,
Carolina Ecosystems, Inc.

Serenity Development
Harnett County
Cumulative Impact Analysis
Per NC Division of Water Resources comment on the above referenced project on 8/10/22, the
information below is provided to address potential secondary and cumulative impacts of the
proposed development, in accordance with the NCDEQ 2004 Cumulative Impact Policy.
The project is located in northern Harnett County, south of the Wake County line (Figure 1).
Hector Creek, a High Quality Water (HQW), drains through the project area. Per Section III of
the above referenced policy, private development projects are unlikely to cause cumulative
impacts unless they are:
(1) relatively large,
(2) involve commercial development, and
(3) occur in otherwise relatively undeveloped landscapes with an impact on regional
growth patterns.
The Serenity Development is relatively large but does not have a commercial component. In
addition, while the site is in a relatively undeveloped landscape, it is reasonable to expect other
developments in the area over time, regardless of this development, due to the continuing growth
expected in nearby Wake County and surrounding areas. Therefore, the project is unlikely to
affect anticipated regional growth patterns.
While the project does not seem to meet all the criteria for private development projects
requiring cumulative impact analysis, the following qualitative analysis is provided to reinforce
that there are adequate protections in place to protect downstream water quality. This analysis
focuses on stormwater management and stream buffer requirements, as these are key to
maintaining downstream water quality. Additional water quality protection, including Flood
Damage Prevention and Sediment and Erosion Control are also applicable in these jurisdictions
and information can be provided if requested.
The project is located in an area with multiple existing local environmental ordinances. As
shown in Figure 1, Serenity is primarily within the HQW and Water Supply Watershed (WSW)
of Hector Creek. Adjacent areas to the north, south and west are within the same watershed.
Adjacent areas to the east are in Phase II and WSW areas. Both Harnett and Wake County have
multiple environmental ordinances protecting water quality that would be applicable to future
development if it occurred in the area.
In Harnett County, where the majority of undeveloped land is located, all potential areas of
development within the project vicinity fall under either:
1) Water Supply Watershed — areas within WSW Protection Area
2) High Quality Waters — within 1-mile and draining to HQW waters
3) Phase II Post -Construction Stormwater — all other areas of the County including WSW
areas outside PA

Serenity — Cumulative Impact Analysis Page 2 of 3
September 9, 2022
Areas within and adjacent to the project fall within the highest category of protection according
to the 2004 policy (HQW/WSW) or have additional regulatory measures of protection (Phase II).
A brief summary of applicable watershed and stormwater ordinances is provided below for
Harnett County, where the majority of adjacent land is located. Wake County, while not
summarized below (due to higher current development and limited adjacent area), has similar
measures in place.
A stormwater permit is required for all new development and redevelopment with a cumulative
disturbance of 1 acre or more. Preliminary subdivision plats and site plans must include a
stormwater management statement which includes:
- USGS & NRCS mapping
- Descriptions of all water courses, impoundments, and wetlands on or adjacent to the site
or into which stormwater directly flows
- Statement noting if the site is within conservation zoning or a watershed district
- Impervious area calculations
- Description of proposed stormwater management system, including:
o BMP preliminary sizes and locations
o Post development drainage map delineating flows to each BMP
o Description and concept for diversion of off -site stormwater
o Pre- and post -development discharges for the 10 and 25-year storms
o Downstream analysis (if post -development is greater than 10%)
• Topography with drainage areas
• Photographs of downstream structures
• Analysis of increased velocity and flooding in existing streams
• Analysis of increased headwater and flooding for existing culverts
• Point where the development is less than 10% of the watershed
• Analysis to demonstrate no adverse impacts in the increase in runoff
• Detention or other improvements to minimize downstream impacts
Stream buffers or setbacks are required in all areas of the County as follows:
- High Quality Waters — 30-foot stream buffers
- Watershed Protection Area — 30-foot stream buffers (100-foot for high density)
- All other areas of the County — 30-foot impervious setbacks for Phase II Stormwater
- Buffers and setbacks are implemented on intermittent and perennial streams, except
WSW applies to perennial features only. Note that WSW areas east of the project are not
within the Protected Area, and therefore would fall under Phase II rules
Construction Plans for stormwater management plans must include:
- Erosion control measures
- Detailed topographic information
- Storm sewer profiles
- 100-year floodplain boundaries and elevations
- All jurisdictional wetland boundaries
- All proposed stormwater management facilities
- Construction details

Serenity — Cumulative Impact Analysis Page 3 of 3
September 9, 2022
- Drainage easements
- Certification by a Professional NC Land Surveyor or Engineer is required for as -built
plans
The summary above is provided to show that there are adequate water quality protections in
place within the immediate vicinity of the proposed development within Harnett County. Further
information regarding the detailed requirements of each ordinance can be provided, if requested.
Per DWR policy, and based on the information provided above, the project:
1. Is not likely to induce growth — the project does not meet all three criteria for private
development that are likely to cause cumulative impacts
2. Is not likely to impact existing uses/water classifications — the project and much of the
surrounding area are within HQW/WSW watersheds
3. Does not require additional regulatory measures — remaining areas of the County are
already under Phase II stormwater requirements
Therefore, the project is not likely to cause or contribute to cumulative impacts on water quality
in the region and a quantitative analysis of impacts is not required.
