On behalf of Retreat at Raleigh, LLC and the Public Utilities Department of the City of Raleigh, Kimley-Horn and
Associates, Inc. is submitting the enclosed Preconstruction Notification Application for authorization to construct the
above referenced project under Nationwide Permit Number 12.
The proposed project includes the construction of approximately 3,500 linear feet of gravity sewer pipeline replacment.
This project will result in exempt temporary impacts to 171 linear feet of stream channel, buffer Zone 1 Impacts of
21,579 SF, and buffer Zone 2 Impacts of 6,687 SF. Mitigation has not been proposed for this project, due to the fact
that the sanitary sewer is being replaced within an existing easement; this opinion was expressed by DWQ's Martin
Richmond during a field review of the stream calls and confirmed by DWQ's Buffer Interpretation/Clarification #2011-
001.
The following information is included with this submittal:
• Review Fee
• Project Summary Sheet
• Preconstruction Notification Form
• Agent Authorization Form
• DWQ Buffer Interpretation Clarification #2011-001
• Permit Maps and Figures
• NCDWQ and USACE Stream Forms
If there is any additional information you need to assist in the processing of this application, please do not hesitate to

2c. River basin: Neuse
3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project site is a linear corridor spanning approximately 3,500 linear feet. The majority of the proposed pipeline will be constructed along an
existing City sanitary sewer easement, where additional clearing will be minimal. The proposed pipe line crosses three existing City of Raleigh
roadways: Buck Jones Road, Lakeside Drive, and Dana Drive; all three roadways are paved with asphalt. This is in a residential area.
3b. List the total estimated acreage of all existing wetlands on the property: 0
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 171
3d. Explain the purpose of the proposed project:
This project is needed to accommodate both an existing deficiency in the capacity of the City's sanitary sewer for current flows and a proposed future
multi-family residential development, The Retreat at Raleigh. This proposed development has served as a catalyst for upgrading the existing sanitary
sewer to a larger capacity. This project will replace the existing sanitary sewer with a new and larger main and will not generate wastewater.
3e. Describe the overall project in detail, including the type of equipment to be used: The proposed project involves the construction of approximately
3,500 linear feet of 12-inch PVC, HOPE, and DIP pipeline, extending from just north of Buck Jones Road to the Walnut Creek Interceptor, south of Dana Drive. The project will extend along the existing
City easement to replace the existing 8-inch VCP sewer. Construction will be performed using two methods: open cut trench (heavy equipment such as bulldozers and excavators to dig a trench, install
the pipe, and backfill) and trenchless pipe bursting. The project corridor will be accessed along the existing easement and City roads. Some clearing of woody vegetation and trees along the easement
will be required for construction of the pipeline, but will be minimzed to allow for the installation and maintenance of the sanitary sewer pipe, manholes, and service connections.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Performed feasibility study to see if it would be possible to pipe burst the entire stretch of sewer to be replaced; this included CCTV of the sewer.
Upon review of the CCTV, it was determined that it is possible to pipe burst some of the sewer, but other sections are not feasible for pipe bursting and
must be replaced via open cut since these sections need to be re-laid in order to achieve a uniform slope. Also, the replacement sewer will be
installed in the same location as the existing sewer in order to keep the impacts within the existing easement.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Sections of the sewer will be replaced via pipe bursting, where feasible. The existing sanitary sewer easement extends along several buffers and
several portions of the sewer need to be re-laid to a uniform slope, so there are some locations that impacts could not be avoided.

MEMORANDUM
Background: Currently in the Neuse (15A NCAC 2B. 0233). Tar-Pamlico (15A NCAC 2B. 0259)_ Randleman Lake
(15A NCAC 2B. 0250). Catawba (15A NCAC 2B. 0243). Goose Creek (15A NCAC 2B. 0607)", and Jordan Lake
(15A NCAC 2B. 0267) Buffer Rules. a buffer authorization and mitigation is required for non-electric utility lines
other than perpendicular crossings with Zone I riparian buffer impacts. Perpendicular crossings are defined by the
afore-mentioned buffer rules as crossings between 75 and 105 degrees. There is also not an explicit use in the table
to address how vehicles can access the utility lines for maintenance that is required.
Problem: Several questions have arisen as to when notification to the Division of Water Quality (DWQ) is required
and when riparian buffer mitigation is required for non-perpendicular. non-electric utility line riparian buffer
impacts ks hen a maintenance corridor is not maintained or a pipe is replaced or upsized. Another question was if the
vehicular access associated with utility line maintenance was considered a prohibited activity since it is not a use in
the table of uses.
Solution: Non-electric utility lines with riparian buffer impacts other than perpendicular crossing scenarios are
outlined in the attached table. If a scenario arises that is not specified in the attached table, DWQ shall make a
determination of when a non-electric utility line-parallel buffer impact would require mitigation.
In addition. the "utility. non-electric, perpendicular crossings of streams" use has an additional item that potentially
allows for impacts to the protected buffers for vehicular access for utility line maintenance.
The attached table outlines the utility uses. whether each use is "exempt". "allowable". or "allowable with
mitigation" and what current table of uses activity can be used to permit these.
For the Goose Creek Buffer Rules, riparian huffier mitigation is required Jnr non-perpendicular impacts lur non-

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to
each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics
identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot
be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where
there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture into a forest), the stream
may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each reach. The total score
assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the highest quality.
