Wet Detention Basin Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
? does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
® does ? does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts:
The proposed impacts to the stream are due to grading and fill associated with construction of the
ready-mix concrete plant. A 60 inch diameter culvert is proposed to bypass the upstream flows
from the north to the south. The project proposes to impact 475 LF of intermittent, unimportant

VIL Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The existing stream runs directly through the center of the site and for any development of the
approved use to take place the majority of the stream will be impacted The proposed
development has underdone multiple changes and revisions in an attempt to avoid and minimize
impacts to the stream channel. However, due to physical and other environmental site constraints
the majority of the existing stream will be impacted by the proposed development
Examples of site constraints are as follows: There are only two locations that contain suitable
soils for a septic field to be located. Due to the existing topography of the site one of these
locations is not feasible. Therefore the location of the septic field is set and can not be relocated
to allow for possible site layout revisions in this area Secondly, the site development
requires a permit from the North Carolina Division of Air Quality. The acceptable location of
the concrete batch plant within in the site is a relatively small area due to property line offset
requirements for this type of equipment Due to this set back requirement the proposed concrete
plant will be located very close to the existing stream bed
Additionally, production facilities that manufacture Ready Mixed Concrete also require a
NPDES stormwater and process wastewater discharge permit The requirements of this permit in
regards to water quality treatment exceed those of the state and county stormwater programs and
require significant surface area for construction of treatment devices All of these requirements
have been considered during the development of the proposed site plan in order to minimize
impact to the existing stream to the greatest extent practical
The stormwater, process wastewater and sanitary wastewater treatment devices the backwater
area generated by the existing 30" CMP culvert the proposed building and plant equipment have
all been arranged to comply with each of the above referenced permits The size of the bypass
Page 6 of 10
culvert has been sized to convey the 100-year storm event and minimize the impact of backwater
on the property and stream channel directly upstream.
The design concept issues preservation of a 50-foot wide natural area along the eastern boundary
and a 25-foot wide natural area along the southern property boundary to help buffer the project's
visibility from US 64. The number of points of access to the site has been limited to avoid
impacts to the natural buffered areas along the right of way of Three Sisters Road. Concrete curb
and gutter has not been used on the western portion of the site in order to convey stormwater
runoff as sheet flow to the existing vegetated buffer and roadside swale. The existing hydrology
of the stream channel has been maintained with a swale from the discharge point of the proposed
bypass culvert to the existing 30-inch CMP culvert to allow the natural flow of stormwater to
continue under the railroad tracks.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/stmigide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Page 7 of 10
Not applicable because the affected stream has been determined by the USACE to be
unimportant and DWQ has determined that the feature is not subject to the Neuse River
Buffer Regulations.
Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please

Zone 2 extends an additional 20 feet from the edge of Zone 1.
** Mitigation only required for buffer impacts at Wetland 313 and Stream 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 213 .0242 or .0244, or .0260.
Not applicable (DWQ has determined that the feature is not subject to the Neuse River
Buffer Regulations)
XL Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level.
The proposed development will disturb approximately 3.6 acres of the 5.97 acre site. Pre-
development conditions for the site include approximately 0.13 acres of impervious area Post-
development conditions for the site include approximately 2.18 acres of impervious area
(approximately 37% impervious) for industrial development and associated improvements.
The nronosed stormwater plan divides the site into two drainage areas_._ The western portion of
the site consists of the operations and maintenance building, parking areas and the driveway off
of Three Sisters Road. This area will sheet flow to a vegetated swale and be carried through
existingL vegetated ditches to the point of discharge from the site. The other drainage area
r t hing to the east of the operations and maintenance building. This area includes
consists of evey
all of the concrete plant equipment and raw material storage areas. Stormwater runoff from this
portion of the site is considered process wastewater and must be treated by devices designed to
comply with NPDES general permit NCG 140000
Page 9 of 10
Nitrogen loading rates will effectively be reduced below the required 10 lbs/acre/year per the
Neuse Stormwater Rule (15A NCAC 28 0235) for the entire site. Adequate storage will be
provided to reduce post-development peak flows to pre-development levels for the I -year storm
in accordance with the Wake County Stormwater Design Criteria. Please refer to the enclosed
Stormwater. Process Wastewater and Erosion Control Analysis. which includes design
calculations for the process wastewater treatment facilities pre vs post-development drainage
area exhibits and design summary worksheets for each proposed BMP.
XIL Sewage Disposal (required by DWQ)
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.
Wastewater will be treated on-site with a conventional septic system.
XI1I. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H ,.0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No ?X
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http•//h2o.enr.state.nc.us/newedands. If no, please provide a short narrative description:
The proposed development will not result in further development within the project area which
could impact downstream water quality.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

Laura,
Your description of my findings at our site visit is accurate. Potential impacts to the unimportant channel will not require prior
notification or mitigation under NWP 39.

From: [e-mail] [mailto:[e-mail]]

Subject: Jenco Site, Knightdale NC
Jamie,
I have attached the map from our site visit on January 23, 2007 to the Jenco site at 512 Three Sisters
Road, Knightdale, NC.
We evaluated one stream on the site, which you determined to be a "5 foot wide, intermittent,
unimportant" jurisdictional feature.
Additionally, we discussed that impacts to this system would not require mitigation under a Nationwide 39
Permit.
Can you concur with the statements made above so as to provide documentation of our meeting and
conversation to stick in the project folder? An email response would be fine.
The project manager does understand that this is not a final jurisdictional determination as you are not
currently issuing JDs.
Thanks!!
Laura

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.
Total Score (from reverse): 52 Comments: Stream quality assessed by Laura Lang
of Kimle -Horn and Associates Inc. and Jamie Shern USACE during on-site evaluation January 23, 2007. Stream was
determined to be "intermittent unimportant".
Evaluator's Signature: Laura Lang Date: January 23 2007
This channel evaluation form is intended to be used only as a guide to assist landowners and environmental professionals in gathering the
data required by the United States Army Corps of Engineers to make a preliminary assessment of stream quality. The total score resulting
from the completion of this form is subject to USACE approval and does not imply a particular mitigation ratio or requirement. Form
