Page 10
SWU-264 June 17, 2015

NPDES RPE Stormwater Permit Application
The Town of Wendell will continue its participation in the Clean Water Education
Partnership. The Partnership conducts numerous TV, radio, website, print and other
outreach campaigns throughout the year and provides a summary of each campaign's
performance in its annual report. Additionally, the Town of Wendell will continue to
employee its website to distribute educational materials and information regarding
stormwater issues.
1.2 Public Involvement and Participation
The Town of Wendell will present its Stormwater Plan at an upcoming Board of
Commissioners Meeting to allow the public an opportunity to review and comment on the
plan. The public hearing will be conducted during a regularly scheduled Town Board
meeting and must be advertised for at least 10 days prior to the date of the hearing.
7.3 Illicit Discharge Detection and Elimination
A. Storm Sewer Map: The town has contracted the services of a vendor to collect field
data and develop a map of its storm sewer system. To date, approximately 60
percent of the system has been mapped. The remaining un-mapped portion of the
system is being developed. The map is being produced in digital form and paper
copies can be produced as needed. Maintenance and verification of the map
components will be ongoing.
B. Regulatory Mechanism: The Town of Wendell's Unified Development Ordinance
(UDO), adopted July 2010, prohibits illicit discharges into the town's storm sewer
system.
C. Enforcement: The town's Public Works staff periodically surveys the storm sewer
system to identify any maintenance needs and to ensure stormwater flows are not
impeded. Any evidence of illicit discharges are reported and investigated.
Additionally, the Town's Code Enforcement Officer routinely surveys near
businesses for evidence of activities that may adversely impact the storm drainage
system. If an issue is observed or reported by a citizen, the officer conducts an
assessment to determine the source, the level of severity, whether containment is
warranted and whether other agencies should be notified. These preemptive actions
and consulting with the property owners allows for corrective measures to be taken
to eliminate adverse impact to the stormwater system.
D. Detection and Elimination: Routine surveys conducted of the stormwater system
include older areas within the town's boundaries that may be more likely to contain
illicit connections. The Town of Wendell has not detected evidence of illicit
connections including floor drains, waste water from washing machines or sanitary
sewer lines, wash water from commercial vehicle washing or steam cleaning and
septic systems. The conveyance system consists of major open ditch channels that
receives all Stormwater conveyed through its underground piped system prior to
discharging into receiving streams. Visual methods would be used to trace the
source of any illicit discharges detected.
Page 11
SWU-264 June 17, 2015

NPDES RPE Stormwater Permit Application
a. Removal of a source of illicit discharge is performed in accordance with the
town's UDO Section 6.2.
b. Written reports will be generated to document the detection of illicit
discharges. The reports will be used in conjunction with the storm sewer
system map to plot a historical record of the discharges. The records will be
maintained to demonstrate the sources, frequency of occurrences, reduction
and elimination of the discharges.
E. Non Stormwater Discharges: All categories are allowable.
F. Outreach: Training is conducted with applicable town staff on detecting and
reporting illicit discharges. Refresher training will be conducted periodically. The
town's website will include information to inform the public and local businesses
about illegal discharges and improper disposal of waste. The website includes
various links including the CWEP website that covers proper disposal of waste.
G. Evaluation: The town will continue to maintain historical records of illicit
discharges develop and maintain the storm sewer system map and train applicable
employees on illicit discharge practices.
7.4 Construction Site Stormwater Runoff Control
The Town Wendell employs the State Sedimentation and Erosion Control Program and
the DWQ general stormwater permit to reduce pollutants from stormwater runoff from
construction activities. Sedimentation and Erosion Control permitting, inspections and
site management within the town are performed by Wake County Environmental
Services.
7.5 Post -Construction Stormwater Management in New Development and
Redevelopment
A. Post Construction Stormwater Management in new development and
redevelopment is regulated through the Town of Wendell's Unified Development
Ordinance adopted July 26, 2010 and the State BMP manual.
B. Operation and Maintenance - The Town of Wendell UDO requires a maintenance
plan and inspection program for each structural BMP built since the UDO's
passage in July 2010. A developer must record, and reference on a recorded plat, a
maintenance plan that instructs the lot owner or HOA about the annual
maintenance tasks and associated costs for at least a 20-year period.
The person responsible for the maintenance of any structural or non-structural
BMP is required to submit an annual inspection report to the Stormwater
Administrator. Among other items, this report must include a statement that all
BMPs are performing properly and are in compliance with the approved
maintenance agreement required by ordinance.
The town may conduct routine inspections, random inspections, inspections based
on complaints or notices of possible violations, or joint inspections with other
Page 12
SWU-264 June 17, 2015

NPDES RPE Stormwater Permit Application
agencies inspecting under environmental or safety laws. Inspections may include
such things as reviewing maintenance and repair records; sampling discharges,
surface water, ground water, or other material in the BMP, and evaluating the
overall condition of the BMP. The owner of a structural BMP must keep records of
inspections, maintenance and repairs for at least five years from the date of the
creation of the record.
C. Open Space Protection — The Town of Wendell requires new residential
development to dedicate open space at the rate of 500 square feet per bedroom,
with an assumption of 3.5 bedrooms per dwelling unit unless otherwise specified.
D. Redevelopment - The Town of Wendell's Unified Development Ordinance
contains standards for areas of redevelopment. All redevelopment within the Town
must have a downstream impact analysis performed. It must also be proven that the
stormwater runoff was not increased as a result of the redevelopment. New
standards were also enacted as they relate to redevelopment in floodplain areas.
Currently no development or redevelopment is allowed within the Flood Hazard or
Buffer Zone. Redevelopment in Special Flood Hazard Areas must also meet
standards set forth by the state and federal governments.
E. Development in Areas with Existing Infrastructure - The Town of Wendell
encourages development in areas with existing infrastructure, especially the
downtown area. The Downtown Mixed Use (DMX) district is coded to encourage
the redevelopment and expansion of the traditional downtown area by having
reduced lot and building dimensional requirements; reduced setback requirements;
not requiring open space for existing buildings which are redevelopment; and
providing a fee in lieu of off-street parking requirements due to the availability of
on -street parking in the area.
F. Mixed Use Development - The Town of Wendell's UDO is form based code,
which by definition, encourages mixed -use development. The UDO established a
Downtown Mixed Use district which encourages the use of buildings in the
downtown area to be arranged vertically with street level commercial and upper
level residential or commercial uses. Higher densities of residential development
are encouraged in this mixed use area.
G. Street Design - The Town of Wendell's standard street sections incorporate planted
median sections with dedicated turn lanes at high -priority intersections with
appropriate tapers, rather than continuous center turn lanes. This practice reduces
impervious area, while still allowing for appropriate traffic flow and turning
movements.
All streets are required to be designed to provide for the discharge of surface water
from the right-of-way of all streets. In less dense areas, vegetated open swale
drainage may be used. As density increases requirements are for either rolled or
vertical curb with closed drainage. An exception to the curb and gutter is made for
development with lots greater than 15,000 square feet. Streets must also cross
natural areas or streams as near to right angles as possible within topographical
limits.
Page 13
SWU-264 June 17, 2015

NPDES RPE Stormwater Permit Application
lieu of curbing so that stormwater may enter landscaped areas designed for bio
retention. A portion of the length of the parking stall may also be landscaped rather
than paved if the landscaped area is below grade and designed as a bio retention
area.
7.6 Pollution Prevention/Good Housekeeping for Municipal Operations
The Town of Wendell has identified its Public Works and Parks and Recreation
facilities to implement its pollution prevention and good housekeeping measures. The
Public Works facility garages the town's heavy equipment and service trucks.
Activities at the site include repair, maintenance, equipment fueling, washing and
storage of vehicles and equipment. Activities at the Parks and Recreation facility
include operation, maintenance and storage of lawn mowers and supplies required for
turf management.
Applicable town employees have been trained on measures to prevent stormwater
pollution. Training includes inspection and maintenance of stormwater devices,
secondary containment, material storage, fueling practices and spill containment.
Refresher training is conducted periodically.
