Stormwater Management Program
2016 Annual Report
1.0 Introduction
This report is a brief summary of the yearly progress of the Stormwater Management Program of
the City of New Bern. The City of New Bern adopted the current Stormwater Ordinance on
March 13, 2001 to meet the requirements of the Neuse Riparian Buffer Rule (15A NCAC
2B.0233) and the Neuse Stormwater Rule (15A NCAC 2B.0235). This report will summarize
the actions of the Stormwater Management Program, from July 1, 20152016 until June 30,
20162017. This time frame will be referred to in the following report as the current reporting
year.
In June 2012, the City of New Bern created a Stormwater Maintenance Division, within the
Public Works Department. The Stormwater Maintenance Division is responsible for the
maintenance of over 60 miles of storm drain piping, 80 miles of drainage ditches, 4000 drainage
structures and 6 stormwater pump stations. The Stormwater Maintenance Division is responsible
for making a variety of repairs and upgrades to the City's drainage system as well as the annual
inspection of over 200 stormwater facilities within the City of New Bern. The Stormwater
Division consists of six full time employees, one or two temporary employees, and three inmate
laborers.
2.0 Illegal Connections and Discharges Elimination Program
Since 1983, the City of New Bern has had a Stormwater Drainage Maintenance Team. In
addition to completing the necessary repairs and the needed new improvements to the
stormwater collection and maintenance system, this group of individuals have also been
screening for illicit connections to the stormwater collection system. During the beginning
years of this program (1983-1988), a significant amount of illicit connections and/or illegal
discharges were discovered and repaired or removed as needed. During this reporting year no
illegal connections and one illegal discharge was discovered during this reporting year. The
illegal discharge was promptly identified and cleaned up. Further detail is provided in Appendix
I.
In an effort to be more consistent, the Stormwater Division has divided the City into four
working zones. Each month staff concentrates their maintenance efforts in a particular zone.
Included in Appendix II, is the levels of service document, maintenance schedule, and the zone
map. Maintenance logs are kept by the Stormwater Division identifying the completion dates of
inspections conducted in the entire city. During these inspections, staff screens the stormwater
system, including any streams, for illicit connections and illegal discharges.
As part of the Stormwater Management Program, the City is required to prioritize areas of the
City in which to conduct dry weather field screening for illegal discharges and illicit
connections. The U. S. Army Corps of Engineers (USACE) completed creating maps of the
entire city in 2010. These maps include but are not limited to:
a. Location of sanitary sewers in the areas of major stormwater collection systems and
the location of areas not served by sanitary sewers
b. Blue line waters
City of New Bern Page 1 of 7
Stormwater Management Program
2017 Annual Report
c. Land uses (categorized but not limited to as undeveloped, residential, commercial,
agriculture, industrial, institutional, publicly owned open space and others...)
d. Major stormwater structural controls
e. Known NPDES permitted discharges to the stormwater collection system
The USACE mapping covered approximately 70% of the City. The information obtained from
the USACE is being incorporated into the City's internal GIS database. This process is about
80% complete and will be released for public use in the next few years.
In addition, City Staff are also conducting GPS mapping of the remaining areas of the City not
covered by the USACE project as well as mapping stormwater BMPs installed prior to 2001.
This overall information is to be utilized to inventory the City Stormwater System and create a
comprehensive Capital Improvements Plan.
During the upcoming year, the Stormwater Drainage Maintenance Team will utilize these maps
created by USACE and others from its GIS office to locate illicit connections found during
routine maintenance activities, as they have in the previous year. In addition, these maps will be
utilized to locate and identify illegal discharges and illicit connections during the dry weather
screenings. Once an illicit discharge or connection is discovered, the City will ensure the
discovery is removed on a timely basis by following the notification and enforcement procedures
specified in the City's Stormwater Ordinance.
3.0 New Development and Nitrogen Reduction
3.1 Acres of New Development
Since April 13, 2001, the City has received a number of plans for planned future developments.
All submitted developments disturbing greater than 0.5 acres are required to obtain a Stormwater
Permit from the City of New Bern.
During the July 1, 2016 until June 30, 2017 permit cycle three developments were issued plan
approval.
3.2 BMPs Constructed in 2016 - 2017
Since the adoption of the Stormwater Ordinance on March 13, 2001, the City of New Bern
requires all new developments over 0.5 acres to apply for a Stormwater Permit. As part of this
application, the developer may be required to utilize a structural best management practice
(BMP) to reduce peak stormwater outflow and reduce total nitrogen loading.
It is the duty of the Stormwater Administrator to keep an inventory of all BMPs implemented
and constructed. As of June 30, 2017, a total of 101 developments were required to implement
one or more BMPs to meet the requirements of the ordinance during the current reporting year.
Attached in Appendix III, is the BMP Inventory which includes site names and BMP types.

3.3 Summary of the City's Use of Mitigation Offset Fees
If the designers of a new development deem to be unable to reduce the total nitrogen export
below the maximum limits as set by the City of New Bern Stormwater Ordinance (March 13,
2001), the owners may make a one-time mitigation offset payment to the City of New Bern and
the Wetland Restoration Fund (North Carolina Ecosystem Enhancement Program) or available
mitigation bank located in the Neuse River watershed in which the applicant is seeking credit.
Currently, fees collected by the City are being utilized to cover the costs of implementing the
Stormwater Management Program and pay for application and plan reviews.
In the upcoming fiscal year, the City plans to use the fees collected to cover the expanding
program costs. These costs will include BMP inspections, public education programs,
consulting, program advertising, etc... associated with the nitrogen removal regulations and the
Neuse Stormwater and Riparian Buffer Rules.
Table 1 below summarized the nitrogen reduction payments made to the North Carolina
Ecosystem Enhancement Program (NCEEP) or available mitigation banks. It should be noted
the City of New Bern only requires payment be made for the required nitrogen reduction amount
and payments are made at the current rate. However the City does require a copy of the sales
affidavit prior to construction.

3.4 BMP Inspections
In order to assure the future impact of utilizing BMPs in new developments, the City is
performing inspections on each BMP installed after April 13, 2001. Upon completion of
construction for each new development, a representative of the Stormwater Management
City of New Bern Page 3 of 7
Stormwater Management Program
2017 Annual Report
Program performs an initial inspection to insure each BMP has been constructed and is in
working order as designed. Around the date of the initial inspection each year, an annual
inspection is performed on each BMP listed on the above mentioned BMP Inventory to ascertain
if all required maintenance is being performed on the BMP and no damage has been sustained by
the BMP to affect its function. If a BMP is found to be in need of maintenance or is failing, the
owner will be notified as such and have 45 days to reply on the planned action for repairs. If the
owner refuses to comply with the City's request, the City has the right to make the repairs
themselves and then charge the costs of the repair as an assessment against the property as
dictated in the Stormwater Ordinance (March 13, 2001). A copy of the BMP inventory can be
found in Appendix III.
During the current cycle NO annual inspections were performed on private BMPs. This was
primarily due to being under staffed. Others were difficult access such as underground devices
or recently completed. The inspection program is being reevaluated and will be revised.
Consideration is being given to self -certifications and City inspections only once every 5 years.
The tracking system for BMPs has primarily been redeveloped and is being refined and verified.
It is anticipated this new system will minimize or eliminate the number of BMPs missed for
inspections.
3.5 Nitrogen Baseline and Net Change
As a part of the annual reporting requirements, a nitrogen baseline and net change in nitrogen
export must be calculated. This data is based upon predeveloped land uses, post developed land
uses, and planned BMP's and pounds of nitrogen purchased. Below is a table summarizing the
Nitrogen Baseline and Net Change for the City of New Bern for the current reporting year, It
should be noted this data only includes those developments required to obtain a stormwater
permit. Those developments below the thresholds for requiring a stormwater permit are not
included. A supporting calculation spreadsheet can be found in Appendix IV.

3.6 BMP Retrofit Locations
It is the duty of the Stormwater Administrator to identify a minimum of two (2) locations
annually within existing developed areas suitable for retrofitting of stormwater BMPs for the
reduction of nitrogen exports and benefit the overall water quality of the watershed.
During the 2016-2017 reporting cycle no retrofit projects were designed or constructed.
4.0 Stormwater Management Public Education Program
4.1 Local Public Education Program
Since the adoption of the Stormwater Ordinance on March 13, 2001, the City of New Bern has
had in place an active public education program dealing with the Neuse River Rules and
Stormwater Management. As a follow up to the developer orientation seminar held in April of
2001, the City has conducted presentations on the Neuse River Rules and Stormwater
Management and the importance of the Nitrogen reduction for several civic organizations
including:
• New Bern/Craven County Real Estate Agents Association
• Swiss Bear Downtown Revitalization Corporation
• Craven County Builders Association
• Craven County Chamber of Commerce
During these presentations the City continued to emphasize the proper storm drain marking
procedures utilizing the appropriate adhesive stickers.
Appendix V provides dates and participation for various public education, outreach, involvement
and participation events during the current reporting year.
The City of New Bern continues to educate the public regarding stormwater management
through its government channel broadcasted on the local cable network.
4.2 Clean Water Education Partnership Program
In addition to the local public education program, the City of New Bern is a member of the Clean
Water Education Partnership (CWEP) Program. The CWEP Program is a cooperative non -point
source pollution education and awareness campaign involving 36 different local governments,
state agencies, non-profit organizations, and a regional council of governments in North
Carolina. The CWEP Program has been established through the cooperative efforts of the
organizations listed below:

City of New Bern Page 6 of 7
Stormwater Management Program
2017 Annual Report
The City of New Bern will continue to expand the public education program currently in place.
Plans for the upcoming year call for continued participation in the CWEP Program. Also,
presentations will be made to as many civic and public groups as possible to educate the public
of the City on the Neuse River Rules and Stormwater Management and the importance of the
Nitrogen reduction. The City hopes these efforts will enable the citizens of the City to be more
open to improving water quality and the overall environmental state of the Neuse River.
5.0 Hotline for Reporting Illicit Discharges
As part of meeting the requirements of Neuse River Stormwater Rules, the City of New Bern
established in 2002, a hotline for the public to report illicit discharges into the City's stormwater
system. This hotline utilizes an existing number in the City of New Bern Public Works
Department (252-639-7501). Callers with complaints are directed to the Stormwater
Administrators extension.
In the instances a call is made after office hours or during a holiday, a recording is heard
directing the callers to leave a message or call an optional number in the case of an emergency.
The optional number allows for a caller to speak to a "live" person who will assist in contacting
the appropriate parties.
During the 2015-2016 reporting year, 355 calls were received on the hotline. These calls dealt
mostly with drainage problems associated with storm drains, ditches, and property development.
There were a few calls associated with illegal dumping. After each call is received, the reported
incident is investigated and appropriate actions taken per the findings of the investigation.
6.0 Land, Easements, and Legal Assurances Acquired for Riparian Buffer
Protection
Since October 1, 2001, the City of New Bern did not acquire any land, easements, or legal
assurances for riparian buffer protection. However, in the upcoming year, the City will correct
and update the current riparian buffer map as any land, easements, or legal assurances are
acquired or as corrections to the existing map are needed.
Currently the City of New Bern requires final plan submissions contain delineated riparian
buffers to be shown and a Declaration of Covenants be recorded for all new developments
containing a BMP. The Declaration of Covenants puts in -place a legal agreement to assure the
maintenance, upkeep, and designed operations of all BMPs, including those sites with riparian
buffers.
7.0 Summary and Actions Moving Forward
During the current reporting cycle the City of New Bern has continued to struggle with
implementation of their Stormwater Management Program. Hindrances to program
implementation include staffing and budget challenges. In the upcoming reporting cycle the City
of New Bern will become responsible for beginning implementation of the NPDES Ph.11 permit
issued March 2016. As part of the NPDES Ph. II implementation the Stormwater Administrator

will reevaluate program elements and seek new methods of achieving compliance. Additionally,
effort will be made to educate the citizens, City staff, City Management and the elected officials
on the importance of the environmental regulations the City is subject to and the need for a
sustainable program.
