I. EXECUTIVE SUMMARY
The City of Greenville has completed its tenth and eleventh annual reports to the NC Division of
Water Resources. This report highlights the following components of our Stormwater
Management Program:
1. New Development Review/Approval
2. Compliance and Enforcement
3. Illegal Discharges
4. Retrofit Opportunities
5. Public Education
The appendices provided include summary tables for new development, illicit discharge
violations and public education back-up information. In addition, the following are updates to
programs or projects managed by the City of Greenville’s Stormwater Management Section to
address community issues associated with stormwater runoff.
Stream Enhancement Program Update:
The Stream Enhancement Program addresses bank erosion along blue-line streams in an effort to
improve water quality, property values and protect the safety of citizens. The program was
intended to provide an avenue for property owners to apply for funding from the City to address
eroded blue-line stream banks located on private property. This program is typically funded
through the Stormwater Utility. During the report period the City did not receive any eligible
applications and the funds were utilized for large capital projects like Town Creek Culvert
Drainage Project and the Watershed Master Plans. The City will continue to accept applications
and rank projects and will resume this effort in 2016 with available funds for eligible projects.
Watershed Master Planning Update:
During the 2012-13 reporting cycle, the City completed the pilot watershed master plan (WMP)
for the Meetinghouse Branch watershed along with the development of standard operating
procedures (SOPs) for watershed master planning. The goals of the WMP included: (1)
evaluating the watershed for existing flooding, water quality, and erosion problems, (2)
recommend and prioritize capital improvement projects to mitigate existing flooding by reducing
the frequency and severity of flooding for property owners, (3) identifying stream stabilization
projects to reduce the risk of property loss along streams and reduce sediment loads as a result of
erosion and (4) identify stormwater BMP retrofit locations to address runoff from existing
impervious areas in order to minimize negative impacts to water quality in the receiving waters.
Since the completion and presentation of the Meetinghouse Branch Watershed Master Plan, City
Council recognized the importance of these plans and their impacts on the Stormwater Utility
Fund. As a result, the remaining watershed plans were completed so that the City can expend
Stormwater Utility funds in a prudent manner. Based on the volume of work (inventory,
modeling and project prioritization), multiple prime contracts were awarded in May 2014 and
completed and presented to City Council in August 2016. The City’s master plans capture public
infrastructure and develop and prioritize projects for both flood retention and water quality
throughout the city.

Long-Term Operation and Maintenance of Structural Stormwater BMPs Update:
The City continues to recognize the importance of long-term maintenance and intends to develop
policies and procedures to address the long-term operation and maintenance of structural
stormwater BMPs associated with residential subdivision development.
Currently, the residential developer turns the long-term operation and maintenance of structural
stormwater BMPs over to a Home Owners Association (HOA) once the development or a
portion of the development is completed. Residential developments that have been built since the
implementation of the State regulations will soon be of an age where extensive maintenance,
beyond routine, vegetative/nuisance management, is required to keep the facilities functioning as
designed. Thereafter, HOA’s are then unable financially to meet the routine and extensive
maintenance program requirements, which then leads to complications for both the City and
HOAs to ensure compliance with long-term operation and maintenance requirements.
It is the City’s goal to develop policies and procedures in the future to address and alleviate these
complications.

IV. PROGRAM ELEMENT: Illegal Discharges
In accordance with the Tar-Pamlico River Basin – Nutrient Sensitive Water Management
Strategy: Basinwide Stormwater Requirements, the City of Greenville developed an Illicit
Discharge/Connection Program. This program establishes the process and legal authority to
detect and eliminate any illegal discharge or connection within the city limits and up to 1 mile
outside the contiguous city limits.
The table presented on the next page is a summary of the violations that were investigated during
this permit cycle and the resulting action taken. In addition, Appendix B includes copies of the
initial reports. As noted in the table several of the issues were reported to the City by crews
working on the WMP. The City also continued to issue multiple door hanger notices throughout
the year at residences and businesses to provide education on the impacts of placing lawn debris
and other materials in the street.
The City of Greenville continues to rely on the NC Department of Environment and Natural
Resources Environmental Help Line for water quality concerns in our area. The number is 1-
877-623-6748. We did not receive any calls as a result of the state hotline during this permit
cycle. In addition, through our pollution prevention education efforts, reports on water quality
concerns have continued to be regularly received at the Public Works Department.
As presented in previous Annual Reports, the City of Greenville has completed the collection
and organization of jurisdiction-wide information identified in the permit. This information was
compiled from various resources such as Greenville Utility Commission’s GIS database, City of
Greenville’s GIS database, NC Division of Water Quality records and NC Division of
Environmental and Natural Resources records. We have completed our annual update of this
information.
In addition to updating our jurisdiction-wide information, the City moved forward with a City-
wide WMP process outlined in the Executive Summary of this report. The WMP process utilized
the SOPs developed to complete a City wide storm municipal separate storm sewer system
(MS4) inventory that collected all MS4 as well as all open and closed systems draining to the
outfall. The inventory was completed with survey-grade GPS and traditional surveying
techniques and is maintained in a GIS geodatabase. Specific to illicit discharge detection and
elimination (IDDE), the inventory process included an assessment of each MS4 structure (inlet,
manhole, outfall…etc.) of whether or not any water flow was present in the system. When
present, the flow was evaluated by the survey crew for odor or discoloration and when such
characteristics were observed, City staff followed-up within 48 hours to determine if an illicit
discharge or illegal connection were present. Such instances are documented and maintained
within the GIS geodatabase for future reference.
As a result of the above outlined plan of action for the MS4 inventory the City has completed dry
weather inspections across our entire jurisdiction. For clarification, the map of the watersheds
inventoried through the WMP process has been provided to represent the outfall screening areas
completed in accordance with the Tar-Pamlico Stormwater Rule.

V. PROGRAM ELEMENT: Retrofit Opportunities
As discussed in the Executive Summary, the City of Greenville completed all of the Watershed
Master Plans. Throughout this planning process numerous locations were identified by citizens,
staff and the consultant (via stream walks) that were either severely eroded or had the potential
for a structural BMP. All locations were assessed and viable locations were prioritized. A
stakeholders group will be formed to further prioritize projects on a City-wide level. The table
below identifies the top 12 water quality and/or stream stabilization projects across the
Meetinghouse Branch Watershed and the estimated cost to design and construction the retrofit:
The project assessment, summary, and map of projects and the project summaries, and sizing
calculations are included on the following pages.

Environmental Advisory Commission Grants
The grant cycles for 2014-2016 were focused on support of citizen activity in stormwater
management education with local youth organizations (i.e. PTOs, science clubs…etc.) as the
focus group. Please see the attached fact sheet for additional information.
The grant of $2,500 for stormwater management education for 2015 was awarded to Love A Sea
Turtle to help with their Upstream Downstream Connection Camp. The mission of the Upstream
Downstream Connection Camp, run by Love A Sea Turtle, is to give as many underprivileged
youth from the area a chance to experience science, nature, and new outdoor activities for no
cost. During this summer alone, Love A Sea Turtle served over sixteen hundred unique students
from more than a dozen local organizations. Thirty-seven student volunteers from nearby public
and private high schools or universities served as camp counselors. The Upstream Downstream
Connection Camp offers a unique opportunity for students to learn about conservation, nature
and its ecosystems, as well as how to enjoy new outdoor activities. This camp also offers an
amazing and unique opportunity for the students to help collect data about the aquatic
ecosystems in the Greenville area.
The goal of the Upstream Downstream Connection camp is to give each student an
understanding of storm water and the possible effects runoff can have not only on the habitats
surrounding it, but also on the oceans downstream. The other goal is to break down the barriers
of fear and ignorance in students who would not normally have the opportunity, resources, or
support to get outside and learn new skills. These activities also help to foster in the students a
deeper respect and care for the environment through experiencing the fun that nature, especially
bodies of water, can offer. The mission of the camp is to teach students about the importance of
keeping their planet and bodies healthy. It is through the free opportunity for these
underprivileged youth to kayak, go on scavenger hunts, bike ride, and fish that the camp mission
is brought to a deeper meaning and hopefully gains a place in the students’ hearts. If the students
learn how much they enjoy being outside and how great it is to be able to kayak and fish in a
clean lake or river, they will be more likely to make positive changes in their lives in order to
keep such places healthy. They will also be more likely to want to share their experiences and
new knowledge with others at school or at home. On top of gaining a deeper respect and love of
nature, they are also provided with the knowledge of how to make a positive difference in their
environment and communities.
At the completion of the grant cycle, representatives from the camp, including students,
presented the project report to the City's EAC during the June 2016 meetings. Attached please
find the final report presented to the EAC.
No applications were received for the 2016 EAC Grant. Funds were instead redirected to
promotional items for the other educational booths and events

Fact Sheets/Brochures/Other Educational Outreach
Informational materials continued to be distributed during this reporting cycle were fact sheets
on common sources of stormwater pollution, protection of riparian buffers and the City’s storm
drain stenciling program along with rain gauges during the annual Pirates Festival event that is
the largest City event of the year. Throughout the year we distribute fact sheets and brochures at
presentations; special events; such as Citizen’s Academy, City Commissions and to the general
public in order to educate on specific concerns.
The City’s Sanitation Division implemented a composting demonstration site consisting of
multiple types of homemade and commercial compost bins. Public Works continues to offer free
workshops and training on the use of compost bins. These workshops discuss the benefits of
composting and after successful completion citizens are eligible to receive free bins for their
residences. The Stormwater Management Program supports this initiative and as a result those
citizens living along eroded streams and ditches take precedence when registering for the
workshop. The resulting mulch from the bins can be used to aid in re-establishing the riparian
buffer along the eroded stream banks.
The City continues to work towards the development of further stormwater related brochures
covering such topics as stormwater requirements for new development and redevelopment
projects, maintenance practices by the City on open and closed storm drainage systems, street
