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 site is currently forested with an existing raleigh sanitary sewer crossing the property in two locations Surrounding
land use consists of a nursing home immediately adjacent to this site (to the north) single family homes to the east and
west Interstate 440 (1 -440) immediately adjacent to the site (to the south) and a City of Raleigh greenway trail that is
located partially along the properties southern boundary (but north of 1-440)
3b
List the total estimated acreage of all existing wetlands on the property
0 acres
3c
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property
0 acres House Creek is immediately south of the protect boundary and is not on this property however the Neuse River
Riparian Buffer associated with House Creek does overlap the project site
3d
Explain the purpose of the proposed project
The purpose of the proposed project is to construct multi family housing (i a townhomes and apartments) and the
associated parking areas The proposed impacts are solely to the Neuse River Riparian Buffer and are associated with
one (1) sewer connection and three (3) stormwater bypass channels (necessary to meet the City of Raleigh Stormwater
Management requirements)
3e
Describe the overall project in detail including the type of equipment to be used
The site will be developed as a multi family residential area but the specific project the applicant is requesting approval
for relates to one sanitary sewer connection (the existing manhole is within the Neuse River Riparian Buffer) and the
bypass /overflow channels for the required stormwater bio retention cels Equipment typical to stormwater BMP
construction will be used including backhoes excavators and dump trucks

D Impact Justification and Mitigation
1 Avoidance and Minimization
la Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
There are no jurisdictional features (i a streams and /or wetlands) on the subject property House Creek however exists
lust off property to the south and therefore the 50 foot protected riparian buffer along House Creek overlaps the subject
property The riparian buffer impacts requested in this application are primarily for the purpose of constructing a
bypass /overflow channel from the stormwater bio retention cel proposed on site This stormwater BMP is designed to
treat all the storm flow that will be generated when this project is completed in compliance with City of Raleigh stormwater
requirements thereby ultimately improving water quality despite requiring a minimal amount of buffer impact to achieve it
There is also an existing City of Raleigh sanitary sewer line that is within the Neuse River Riparian Buffer that this project
must connect to which results in additional riparian buffer impact All impacts are listed as allowable within the Neuse
River Riparian Buffer Rules Table of Uses
1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
The project will meet with the City of Raleigh requirements for Sediment and Erosion Control practices
2 Compensatory Mitigation for Impacts to Waters of the U S or Waters of the State

6h Comments The buffer impacts requested are minimal in nature and required primarily to construct the bypass /overflow
channel from the proposed stormwater bio retention cels being built to treat the stormwater generated by this project
when completed It is our understanding that from previous meetings the project engineer (Mr Johnny Edwards) had with
Ms Annette Lucas ( Stormwater Engineer for NC DWQ Central Office) on similar projects that this proposal is in
accordance with DWQ expectations for this BMP device Additionally there is a minor amount of buffer impact
associated with a sanitary sewer connection to an existing manhole that is currently within the protected riparian buffer It
is also our understanding that these impacts are allowable per the Table of Uses

Stormwater Management and Diffuse Flow Plan (required by DWQ)

Diffuse Flow Plan
la
Does the project include or is it adjacent to protected riparian buffers identified
®Yes ❑ No
within one of the NC Riparian Buffer Protection Rules
1 b
If yes then is a diffuse flow plan included? If no explain why
Comments This project is proposing bio retention cels to capture and treat all
stormwater runoff generated by this project upon its completion Bio retention cels
are permitted to discharge directly to a surface water and therefore no diffuse flow
is required The minor amount of buffer impact requested in this application is
❑ Yes ® No
associated with the bypass /overflow channels for these devices The other minor
riparian buffer impact is for a sanitary sewer connection which does not require
diffuse flow (i a no new impervious surface is associated with the sanitary sewer
connection)
2
Stormwater Management Plan
2a
What is the overall percent imperviousness of this project?
53%
2b
Does this project require a Stormwater Management Plan?
❑ Yes ® No
2c
If this project DOES NOT require a Stormwater Management Plan explain why As this project is not requesting DWQ
401 Approval the Stormwater condition within the General Certifications does not apply to this project and therefore no
DWQ Stormwater review is required However the City of Raleigh does require stormwater treatment for the proposed
development which is why the applicant has chosen to install bio retention cels on the property to handle the stormwater
run-off generated by this project at its completion

❑yes No
additional development which could impact nearby downstream water quality
3b
If you answered yes to the above submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy If you answered no provide a short narrative description
We have reviewed the DRAFT Internal Policy Cumulative impacts and the 401 Water Quality Certification and Isolated
Wetland Programs document prepared by the NC Division of Water Quality on April 10 2004 version 2 1 The draft
states that many private development projects including small multifamily developments are unlikely to cause cumulative
impacts This project does not meet any of the three criteria of private projects that can clearly result in cumulative
impacts The proposed development is relatively small in nature is within a mostly residentially developed landscape
bounded by existing residential developments and Interstate 1 440 and therefore the utility infrastructure (i a water and
electricity) are already in place to service the proposed development We anticipate that you will advise us if a qualitative
or quantitative impact analysis is required
4
Sewage Disposal (DWQ Requirement)
4a
Clearly detail the ultimate treatment methods and disposition (non - discharge or discharge) of wastewater generated from
the proposed project or available capacity of the subject facility
