7. STORMWATER MANAGEMENT PROGRAM
7.1 Public Education and Outreach on Storm Water Impacts
The target audience includes, but is not limited to: households, civic groups and the
business/development community.
The Town of Clayton's public education program will target nutrients, trash, yard
waste and sediment to begin with. Future pollutants may be added as necessary. These
pollutants are the major concerns for the Neuse River Basin. The Town will expand the
public education program to include other named pollutants as they become a problem for
the area. In addition to participation with NC Clean Water Education Partnership, the
Town will utilize bill stuffers/back of bill messaging, Town website, PEG channel, festival
booth sponsorships, public workshops and public forums.
The Town of Clayton's public education and outreach program will continue to develop
it's comprehensive Annual Education Plan. The Education Plan will include the
specific Public Education/Outreach BMP's to be implemented, a schedule for the
implementation and targeted audiences for each BMP and measurable goals for all aspects
of the Plan.
The public education measure will be evaluated in several different ways: # of
educational events, estimated number of educational participants, bags of trash removed
and statistics from the NCCWEP for radio and TV ads.
7.2 Public Involvement and Participation Program
The Town of Clayton will implement a public involvement and participation program to
include all required program elements. Public notification will especially be important
during the development and approval of all new ordinances and ordinance modifications
that will be a part of the Town's stormwater management program. The Town will
actively strive to involve all potential stakeholders in its public involvement and
participation program. Those stakeholders include: Town citizens, commercial and
industrial businesses, the development community, trade organizations, homeowners
associations and education organizations.
5

The Town of Clayton already has established public notification processes and
procedures for standard Town legislative activities. The Town Council meetings
are open to the public and time is made available for public comment. In
addition, any ordinance revisions are open to public review and comment before the
Town Council can adopt them. These existing procedures will be used during further
development and implementation of the Town's Stormwater Management program. In
addition special public meetings and information sessions will be held as needed
throughout the implementation of the new programs.
7.3 Illicit Discharge Detection and Elimination
The Town Council will adopt an Illicit Discharge Ordinance in accordance with the
required timelines.
When an illicit connection is identified, written notification will be provided to the
apparent responsible party. Time will be given to offender to take the necessary
corrective action depending on the nature of the offense. Also depending on the
nature of the offense, civil or criminal penalty may be instituted. If offender refuses
to comply, the case will be turned over to the Johnston County District Attorney's
Office.
Random dry weather inspections will be conducted by various Town staff. To locate
problem areas, Town crews will be cross -trained to conduct proper inspections. Water
will be sampled periodically. Complaints from citizens will be investigated. The Town
staff will constantly assess and evaluate the program as well as meet regularly with
other municipalities to address regional needs and concern. Changes and
amendments will be brought before the Town Council for prompt approval as necessary.
The public and Town employees will be informed and educated on the hazards of
illicit connections and illegal dumping as part of the Town's Public Education
`Program and your Good Housing Keeping Program. This will be met through the
Town's Public Education system which will include mailings and postings on the Web
site.
7.4 Construction Site Stormwater Runoff Control
The Town of Clayton relies on NCDENR Division of Land Resources
to administer Sediment and Erosion Control.

7.5 Post Construction Stormwater Management in New and Redevelopment
The Town of Clayton Unified Development Code (UDC) contains a
high density option to control of post -construction stormwater runoff. The
current program was developed to comply with the State's Watershed Water Supply
Protection requirements and the Neuse NSW requirements for urban stormwater. The
current program addresses storm water runoff from new development and
redevelopment projects that disturb an area greater than or equal to one acre. All
projects nuq control peak flow and meet designated water quality targets.
The Town of Clayton Unified Development Code (UDC) requires
preservation of open space in new development. The UDC also contains a
tree preservation requirement. The Town is currently a Tree City
USA program participant. All trees located throughout the Town of Clayton
make up the "Urban Forest." Trees located in the Town public right-of-way and on
Town property are municipal -owned trees. Trees provide a wide variety of social,
community, economic and environmental benefits for us all that include such things as
climate moderation, better air quality, water conservation, habitat for birds and other
wildlife and increased property values. The Town of Clayton is responsible for the
planting, protection, maintenance and removal of these trees.
7.6 Pollution Prevention/Good Housekeeping for Municipal Operations
The Town of Clayton will develop and implement an operations and maintenance
program that includes a training component w it h goal of preventing or reducing
runoff from municipal operations. Using training materials that are available from
EPA and other organizations, the Town will train employees to prevent and reduce
storm water pollution from activities such as parks and open space maintenance, fleet
and building maintenance, new construction and land disturbances and storm water
system maintenance.
The following Town of Clayton facilities and operations are impacted by this operation
and maintenance program. These programs will be evaluated and revised to ensure
that the programs minimize pollutant loading. Facilities will be inspected to identify
and eliminate exposure to stormwater. Corrective actions will be taken or BMP's
installed as needed:
1. Parks and Recreation Areas
2. Emergency Services (Police and Fire Departments)
3. Public Owned Open Spaces
4. Salt/Sand Storage Areas
5. Fleet Maintenance
6. Vehicle Washing Facilities
7. Material Storage Facilities
8. Parking Lots
7

Streets and Town maintained parking lots are routinely cleaned and cleared of any debris.
Streets are currently swept regularly. The Public Works Street Division currently inspects
the storm system including grates, catch basins and rip rap aprons for accumulated debris.
After the initial assessment and inventory of the Town's maintenance facilities, the Town
will educate staff on how to reduce pollutants from public parking lots, materials
storage yards, outdoor storage areas at vehicle maintenance shops and any other publicly
maintained facilities. The Town will record the number of employees attending a
pollution reduction educational meeting. The number of facility cleanings and amount of
pollutants collected will also be recorded.
