PROJECT SUMMARY
River Bend BMP
Stormwater Wetland
EEP #668
Synopsis
EEP's River Bend BMP site (EEP #668) is a stormwater wetland BMP located in River Bend, North
Carolina within the Neuse River basin CU 03020204. The project was initiated by NCEEP to offset
nutrient loading as a third -party credit provider in the Neuse River basin (15A NCAC 02B .0240).
This site was selected because it will treat a large, fully developed watershed. There was an existing
undersized, under- performing BMP at the site that was expanded and modified for improved water
quality benefit to the receiving water. The current property owner (Town of River Bend) was strongly
supportive of the project. A stormwater treatment wetland works well in the area because of a consistent
water source from the large watershed. The visual appeal of a wetland is a significant benefit as the site is
heavily trafficked. NCSU recommended this site to EEP as it was a rare opportunity to find a location in
the Neuse River Basin that can treat 115 acres at such a low cost and with property owner cooperation.
The stormwater wetland is designed to remove 193.73 lbs /year of nitrogen, generating a 30 -year credit
value of 5811.9 lbs reduuctiori of '1L'otaIl Nitrogen. Additionally, the project is designed to reduce 785.4 lbs
of total phosphorous (TP) over 30 years; however, TP reduction credit is not available in the Neuse River
basin.

SCOPE OF WORK
A. Introduction
The mission of the NCDENR Ecosystem Enhancement Program (EEP) is to restore,
enhance, and preserve wetlands, streams, and riparian buffer areas, and to reduce the
discharge of nutrients into surface waters throughout North Carolina's 17 major river
basins with the overall goals of improving water quality, in- stream and riparian habitat.
EEP is interested in restoring and protecting the watershed functions of the Trent River
Drainage area, which includes the Town of RIVER BEND (TORB). The construction of
stormwater treatment systems, commonly referred to as Stormwater Best Management
Practices ( Stormwater BMPs) is an accepted method of improving water quality by
reducing nutrient discharges into surface waters of the State. This scope of work (SOW)
will be used to develop a Memorandum of Agreement (MOA) between EEP and TORB
for a Stormwater BMP to be located on property owned by TORB.
B. Background
The purpose of this SOW is to define and set forth the responsibilities of TORB and EEP
for the design, construction and maintenance of a Stormwater BMP. The entire costs -
associated with the design and construction of the Stormwater BMP will be funded by
EEP through other contracts. Maintenance of the Stormwater BMP to ensure proper
function will be the responsibility of TORB and no monies will be paid to TORB. The
Stormwater BMP will be constructed on a parcel of land located near the intersection of
Plantation Drive and Shoreline Drive in River Bend, Craven County, North Carolina.
The project site is identified as PIN # 8- 201 -040 in the Craven County Register of Deeds.
The Project is intended to enhance water quality within the Trent River Drainage Area
(Cataloging Unit # 03020204, Hydrologic Unit 03020204010100) through the reduction
of nitrogen and phosphorous discharges into surface waters within the watershed. This
reduction is to be accomplished through the use of a Stormwater Wetland BMP as
outlined in the RIVER BEND PROJECT STATEMENT, a copy of which is attached
hereto as ATTACHMENT 1. It is anticipated that the Stormwater Wetland BMP will
reduce Total Nitrogen discharges from the 115 acre sub - watershed by approximately
40 %, or 194 pounds per year, and Total Phosphorous discharges by approximately 35 %,
or 26 pounds per year.
C. Scope of Work
Tasks and Responsibilities for TOWN OF RIVER BEND
The Project is located entirely on property owned by and within the jurisdiction of
TORE.
The primary responsibilities of TORB during and after construction of the Project will
be:
A
ATTACH MENT-A

both entities. Both entities also agree to work cooperatively to develop a remedial
action plan (RAP) that is agreeable to both entities in the event that post - construction,
remedial activities are necessary. Details related to the implementation of the RAP
will be jointly discussed by both entities as necessary.
2. To provide a designated contact person from TORB to coordinate and review all
aspects of the Project with EEP and its contractors or consultants. TORB will
respond in writing to any Project approval request within thirty (30) days frorn the
date of request. If TORB fails to respond within thirty (30) days of the request, the
request will be deemed approved by the TORB.
3. To provide and ensure that EEP, its contractors and its consultants will be allowed
reasonable access to the Stormwater BMP Project work site during normal working
hours.
4. To provide for public safety and work place security ' by keeping work areas closed to
the public as necessary throughout the constructions phases of the Project.
Contractors will follow standard OSHA guidelines and will post the construction site.
5. TORB will designate a contact person and/or Public ' Information Officer that will
notify or consult with EEP prior to issuing news releases relating to the Project..
6. To meet with EEP and/or its contractors and consultants at least every two months to
review and assess the Project's plans and progress.
TORB will submit a Stonnwater BMP maintenance and inspection report to EEP
every two (2) years for a period of thirty (30) years at no cost to EEP.
TORB will maintain the Stormwater BMP to ensure functionality for a period of 30-
Y
ears at no cost to EEP.
Tasks and Res onsibilitles for Ecas stun Enhancement Pro ram
The primary responsibilities of EEP during and after this project will be:
I . To work cooperatively to develop and implement a design plan that is agreeable to
both entities. Both entities also agree to work cooperatively to develop a remedial
action plan (RAP) that is agreeable to both entities in the event that post-construction
remedial activities are necessary. Details related to the implementation of the RAP
will be jointly discussed by both entities as necessary,
2. To design and construct the stormwater BMP at no cost to TORB.
3. To consult with TORB's designated contact person and/or Public Information Officer
and staff prior to issuing news releases relating to the Project.
ATTAfC,HMENT_A,,_
4. To meet with TORB staff to review and assess the project's progress, as specified
in Section 3, item No. 5 of this SOW. A minimum of Four (4) meetings will be held
with TORB to discuss the Project and receive input. These meetings will be held
after preparation of the Draft Design Plan (30% complete design), after preparation of
the Final Design Plan, prior to the Pre - Construction Meeting and prior to the Post -
Construction Meeting.
5. To obtain any state, federal or local permits necessary for construction of the Project.
D. Timeline and Duration of this A reement
The Project shall commence on the date a Memorandum of Agreement (MOA) is signed
by all parties. The site maintenance phase of the Project will commence upon completion
of the Stormwater BMP construction. TORB agrees to maintain the constructed
Stormwater BMP site for a 30 -year period and submit site maintenance and inspection
reports to EEP every two (2) years for a period of thirty (30) years following completion
of the construction phase of the project.
E. Limitations

maintenance responsibilities for the Project from TORB to EEP. All provisions of the
MOA will be consistent with such understanding.
2. If either party fails to perform or comply with any condition of the MOA, and should
such failure continue more than 30 -days after written notice from the other party, and if
the non - compliant party should not within 30 -days commence to cure the failure with due
diligence, the aggrieved party may terminate the MOA on written notice to the non-
compliant party, termination to be effective not less than 15 days from the date of the
written termination notice.
3. The failure of either party to insist on strict performance of any condition of the MOA
shall not be construed as a waiver of the right to insist on the performance of that
condition in any other instance.

Tar - Pamlico Stormwater Rule 15A NCAC 2B .0258 Last Modified 8/8/2013
Introduction
The set of Nvorksheets included in this file will enable stormwater permit applicants to comply with, and local
governments to administer, the nutrient loading requirements of the Tar - Pamlico StormNvater Rule, 15A NCAC
213 .0258. The file contains a set of Nvorksheets for estimating nitrogen and phosphorus export from a
development project prior to and following development, and following the installation of best management
practices (BMPs) on the development. Supporting information on the design of the Nvorksheets can be found in
the document, Tar- Pamlico River Basin: Model S'tormwater Program for Nutrient Control, available from local
governments implementing the stormwater rule and the NC Division of Water Quality staff contact for the Tar -
Pamlico nutrient strategy, in the Nonpoint Source Unit of the central DWQ office, Raleigh, NC. The
information may also be downloaded from the Division of Water Quality's Tar - Pamlico web page at
http:// h2o. enr.state.ne.us /nps /tarpam.htm.
This file contains Nvorksheets with the following elements:
1. Definitions of Land Use Terms Used in Spreadsheets (this page)
2. Residential Worksheet when Footprints are not Shown (1 pg.)
3. Export Calculation Worksheet for Coastal Plain Communities (1 pg.)
4. BMP Removal Calculation Worksheet for Coastal Plain Communities (3 pp.)
Definitions of Land Use Terms Used in Spreadsheets
Transportation impervious: The portion of the development that is taken up by roads, driveways, parking
areas, Nvash pads or any other facility designed for vehicular use, maintenance or storage. Transportation
impervious includes areas covered in pavement, gravel, pavers and dirt.
Roof impervious: The portion of the development that consists of roofs of buildings and garages that serve
single - family homes. Commercial parking garages shall be considered as transportation impervious.
Managed pervious: The portion of the development that consists of vegetated areas that the landowner could
manage by moNving, logging, applying fertilizer, etc. Although residential development may include pervious
areas that are initially undisturbed, these areas must be considered as managed pervious (instead of Nvooded
pervious) unless they have conservation easements or another mechanism to insure they will not be managed.
Also, the land in Zone 2 (the outer 20 feet) of a protected riparian buffer must be considered as managed
pervious area unless it is protected by a conservation mechanism.
Wooded pervious: The portion of the development that consists of forested areas that are permanently
protected by a conservation easement or other binding conservation mechanism. Also, wetlands and the land in
Zone 1 of a protected riparian buffer (the first 30 feet adjacent to a stream) may be considered as Nvooded
pervious area.

Last Modified 8/8/2013
Residential Worksheet when Footprints are not Shown
Use this worksheet when building footprints are not known to determine the acreage in each of the four categories -
transportation impervious, roof impervious, managedpervious, and woodedpervious - in the development. You
will need these acreages for both the "Export before BMPs" and "Export after BMPs" worksheets. For the
"Export after BMPs" worksheet, you will need to subtract the acreage occupied by BMPs from the managed
pervious acreage produced by this worksheet. Also for the "Export after BMPs" worksheet, if the development
contains more than one catchment, use this worksheet for each catchment.

Directions:
> In the two green spaces in the box below, enter the average lot size and the percent of the right -of -way that is
impervious within the development.
> In the table below, for the type of land cover listed for each column, enter acreages in the green boxes beneath.
> In the "Lot Area" column, be sure to enter acreage within lots that is protected by a conservation easement, the Tar -
Pamlico buffer rule, or ivetland rules in the green box in the lower lefthand corner (enter "0" if there is none). If lots
are drawn to exclude protected lands that are part of the total development acreage, enter the acreage of those protected
lands as wooded pervious in the "Community Areas" column.
> The spreadsheet will compute all values in the light blue shaded boxes.
> NOTE: In the "Community Areas" column, v ou will need to ensure that the various component acreages sum to the
value in the "TOTAL" box at the top. The spreadsheet will not correct for inconsistencies. Any inconsistency between
the total value and the sum of individual acreages will carry over to column (5).
Average lot size = 0.5 ac (Must show building footprints if lot size < 0.13 ac.)
% impervious in right -of -way = 50 %

Directions (same for pre - development and post - development tables):
Enter the acres of each type of land cover in the green boxes. The spreadsheet will calculate all of the values in light blue.
Compare total areas of development in pre- and post - tables for consistency (bottom of column (2)), and also for consistency with
the site plans. If all of these values are not the same, there is an error that must be corrected.
�� Unless drainage onto the development from offsite is diverted around or through the site, offsite catchment area draining in must
be included in the acreage values and treated.

Note: The nutrient loading goals are 4.0 lb ac yr for IN and 0.4 lb ac yr for TP. If the post - development nutrient
loading is below these levels, then no BMW is necessary. Otherwise, the next worksheet calculates
post - development IN and TP loadings after BMPs are installed.

Directions:
� It may be advantageous to split the development into separate catchments to be handled by separate BnIPs. The tables below allow
the development to be split into as many as three catchments, and can be copied for greater than three.
NOTE: Unless runoff flowing
onto the development from ofs;ite is routed separately around or through the site, the ofs;ite catchment
area draining in must be
included in the acreage values of the appropriate land use(s) and treated.
Above each table: Enter the catchment acreage in the top green blank. Based on a comparison of the
post - development TN and TP
export coefficients you calculated above to the rule requirements of 4.0 lb ac NT TN and 0.4 lb ac NT TR
select BnIP(s) from the list for
treating the catchment runoff. Enter the chosen BnIP(s) nutrient removal rates in the green blanks. If more than one BnIP is to be
used in series, the combined removal rates will be calculated automaticath, in the blue blanks.
Catchment Tables: Enter the acres of each type of land cover in the green boxes. The spreadsheet
will calculate all of the light blue
boxes. NOTE: Compare the Total Catchment Acreage for the Development (final table) to the value yon
established in the pre -BnIP
worksheet tables, and also to the site plans, for consistency. All of these values need to be the same

Note: The nutrient loading goals are 4.0 lb ac NT for TN and 0.4 lb ac NT for TP. If the post-development nutrient
loading is below these levels, then the BI\lF`s planned are adequate. Otherwise, additional BI\lF`s and or
modifications in development plans are required.

Dear Ms. Miguez:
45 Shoreline Drive
River Bond, NC 26662
T 252.6383870 .
F 252.638.2580
www.riverbendnc.org
I am writing to respond to your request for an inspection and maintenance record for the Ecosystem
Enhancement Program (EEP) project constructed in the Town of River Bend just off Plantation Drive.
We regret that this report is tardy; however, the Town is aware of its responsibility to maintain this
structure in accordance with the January 25, 2006 contract.
The project is located across a recreation field that is adjacent to Town Hall and is inspected
frequently. The condition can be described as follows:
1. There has been no encroachment on the structure.
2. The side slopes of the site are stable.
3. There is no construction taking place in the watershed that feeds this wetland.
4. There is no evidence of silting occurring in the project area.
5. The Town recently posted an updated sign explaining the wetlands project for the
educational value of residents who use an adjacent walking trail.
6. NC State University has established a water quality monitoring station at the entrance
point for stormwater and also at the discharge point from the wetland. We have recently
requested to receive periodic updates of the results of this monitoring effort.
7. The Town has scheduled the maintenance excavation of the "fore bay" to be accomplished
during the current budget year.
We find that this project has advanced our citizens' understanding of stormwater issues. This
educational aspect of the project is helpful as we address stormwater issues throughout the Town.
If we can provide any additional input to you and your staff, please contact us. We appreciate your
office's interest in BMP stormwater management, and we wish to be a good partner.
Sincerely,
of n rrkla` d°
Mayor
