City of Thomasville Stormwater Annual Report
2024—2025
Introduction
On July 1, 2005,The North Carolina Division of Water Quality(DWQ) in the Department of
Environmental Quality(DEQ), formerly DENR, began issuing Phase II stormwater permits to
municipalities in North Carolina under the National Pollutant Discharge Elimination System Program
(NPDES). At the time, the NPDES Phase II Program was the latest stormwater program stemming from
the Federal Clean Water Act of 1972. Prior to the Phase II program, EPA and NC DEQ had issued NPDES
Phase I Stormwater Permits to Cities larger than 100,000 persons. In North Carolina these cities were
Raleigh, Charlotte, Fayetteville, Durham, Greensboro, and Winston Salem.The Phase II Program
included distribution of Phase II permits to municipalities less than 100,000 residents and began with
municipalities within Municipal Spheres of Influence (MSI)that were greater than 50,000 citizens. The
City of Thomasville is included with the City of High Point and City of Greensboro as a Municipal Sphere
of Influence.

The Phase II stormwater program was created with the intention of improving the quality of the nation's
waterways by reducing the quantity of pollutants that stormwater transports into stormwater systems
and discharges to surface water bodies. The permit requires permittees at a minimum to develop,
implement, and enforce a stormwater program designed to reduce the discharge of pollutants from the
municipal separate storm sewer system (MS4) to the maximum extent practicable.
Page 3 of 15

City of Thomasville Stormwater Annual Report
2024—2025
The stormwater program is composed of the following six management measures:
1. Public Education and Outreach
2. Public Involvement and Participation
3. Illicit Discharge Detection and Elimination
4. Construction Site Runoff Controls
5. Post-Construction Site Runoff Controls
6. Pollution Prevention and Good Housekeeping for Municipal
Operations
Each of these measures consists of required Best Management Practices (BMPs), measurable goals for
each BMP and an implementation schedule for the 5 year permit cycle. Additionally, the City of
Thomasville has a Comprehensive Stormwater Management Program (CSWMP) and completes annual
reporting about the NPDES Phase II Program. Because the NPDES Program concentrates on water
quality it has limited provisions concerning water quantity and flooding controls.
In early 2017, NC DWQ issued a renewal of the City's NPDES Phase II Permit. This renewed permit is
similar to the previous permit with a few minor changes.A copy of the permit is available either through
Josh Johnson, P.E. or through NC Division of Energy, Mineral and Land Resources (NC DEQ—NPDES—
MS4 Program). The updated SWMP, submitted to DEQ in May 2025, is under review per 2021 audit.
When approved,the MS4 permit renewal will be issued.
This report is intended to complete the Annual Report specifying the City's progression in implementing
the NPDES Permit and Comprehensive Stormwater Management Plan. It is also a staff review of the
items implemented during this fiscal year. It provides readers with a comprehensive idea of the City's
full Stormwater Program.
NPDES Phase II Minimum Control Measures
Each of the 6 Minimum Control Measures (MCM's) has a set of best management practices (BMP's)that
are intended to foster compliance with both the City's Permit and CSWMP.These specific BMP's can be
found in both the Permit and the CSWMP but highlights and specific actions will be noted in the report.
Public Education and Outreach
The City operates a Public Education and Outreach program that is designed to educate the general
public about the need to improve water quality in stormwater.The general objectives are to distribute
education materials to the community and/or to conduct equivalent outreach activities about the
impacts of storm water discharges on surface waters and the steps the public can take to reduce
pollutants in stormwater runoff. These objectives have been further refined to target residents, school
Page 4 of 15

City of Thomasville Stormwater Annual Report
2024—2025
children, local businesses(specifically gas station owners and landscaping companies) and industry
because these groups have the most impact on stormwater pollution prevention.
The education program targets total suspended solids (TSS and Sediment) and nutrient loading because
turbidity, sedimentation, and nutrients are the pollutants of concern in downstream waters.
The City partners with Stormwater SMART, an education and outreach organization hosted by the
Piedmont Triad Regional Council (PTRC). Stormwater SMART is a cooperative group that is funded by
several Piedmont municipalities. It was created in 2005 to provide education and outreach for MS4
Permittees (like Thomasville) and concentrates on direct education of school children and residents.
Danica Heflin is the Stormwater Smart Outreach and Education Coordinator; Danica Heflin can be
contacted at [e-mail] or at(336)904-0300 ext.3008.
A copy of Stormwater SMART's Annual Report is available upon request. It provides a comprehensive
look at the in person and virtual educational programs presented in Thomasville for the Fiscal Year 2024

SMART website link for educational material is posted on the City website: (https://www.thomasville-
nc.gov/departments/public works/stormwater program.php). For community outreach,the Parks
Department sponsored Miss Thomasville to work with after schoolers on Water Conservation and Safety
on March 26, 2025.

2024—2025
Public Participation and Involvement
The City has a responsibility to solicit and consider public opinion on all matters, including stormwater
management.The City originally involved the public with a public hearing in 2006 and tried to create a
citizens' committee during the first permit cycle, but little interest was shown by the public.The City has
been receptive to any questions from citizens, maintains a Helpline-(City Hall at(336)475-4210 as well
as a Sanitary Sewer Overflow reporting form on the website)and has worked with Stormwater SMART
to educate the public but continues to struggle to establish effective Public Participation and
Involvement. Future public meetings will allow citizens to provide input on the stormwater program,
and this will provide a platform for the city to educate its citizens as well.
The City Beautification Committee and Keep Davidson County Beautiful organization perform monthly
litter sweeps. Information can be found on city website link, https://www.thomasville-
nc.gov/government/boards committees/city beautification commission.php. Events are publicized
on Stormwater Smart Calendar too. There are typically six to twelve volunteers at each event. These
events are largely successful with approximately 25 to 40 bags collected monthly. Each activity promotes
public involvement and public education.
Illicit Discharge Detection and Elimination
The City of Thomasville has a full Illicit Discharge Detection and Elimination (IDDE) Program.The IDDE
Program is intended to reduce discharges to the stormwater system that are not entirely composed of
stormwater.There are a few permitted discharges and firefighting related discharges that are allowed.
An illicit discharge is typically dirt, soap, pet waste, litter, oil, fertilizer, pesticides, or raw sewage and
often times comes from "generating sites." Generating sites are points of pollution that continue over a
period and are recurring at regular or irregular intervals. One hotline related call was addressed.
Residents were setting used motor oil on the curb for collection. City staff visited with residents and
educated them on proper disposal of used oil.
The backbone of the IDDE program is the IDDE Ordinance that the City passed in 2006.The IDDE
ordinance provides permits specific discharges into the MS4 as legal, provides legal authority to restrict
illegal discharges, prohibits illicit connections, provides conditions for cleaning up and preventing
polluted spills, provides for right of entry into property to investigate prohibited activities, and provides
the City with options for enforcing the Ordinance.The IDDE Ordinance is based on the NC DWQ's Model
Ordinance.
The second basis for the IDDE program is the City's MS4 Map.The mapping program was completed in
the first permit cycle by GPS mapping and is now usable in an AutoCAD format.The map includes the
entire MS4 system and provides easy access to aid in the investigation of illicit discharges.An

investigator with the map could find an illicit discharge and then easily follow the flow of the discharge
upstream until finding a source of the discharge.

MS4 Map
The map was originally published as a map book but generally is used on a watershed basis or through
AutoCAD and the City's Engineering Department. If a specific area is needed it can be printed by either
Stormwater or City Staff.The map is intended to be updated on a regular basis as new development
happens but updates since the completion of the map have been sporadic.A future improvement to the
MS4 map would be a conversion from CAD to GIS and the use of GIS by the City of Thomasville.
The IDDE program also includes dry weather testing of outfalls into the stream system. In the first
permit cycle this was conducted in coordination with the mapping. Outfalls that had dry weather flows
were reported and investigated. Since the first permit cycle, most dry weather flow testing has been
done in conjunction with complaints or City staff investigations. In 2022-2023, stream walks were
conducted. Identified issues were logged.
The City has ongoing issues with its collection system that have resulted in multiple sanitary sewer
overflows (SSO) annually.The City had 10 SSO's during 2024-25 that were reported by city staff. The
causes included natural conditions (6), debris in line (1), pipe failure (2), Other(1). Only three required
physical repairs, all of which were completed. The City is working hard on improving the collection
system and reducing SSO's but improving the collection system will take several years to reach
compliance.
The Capital Improvement Projects: Rains Road Pump Station and Forcemain upgrades and the Sanitary
Sewer Asset Inventory and Assessment, amounted to $8,492,968. Phase 1 of Jimmy's Creek grant has
Page 7 of 15

City of Thomasville Stormwater Annual Report
2024—2025
been completed, and Phase 2 is under contract,which includes possible realignment of the creek and
other bank remediations. The goals of these projects are to reduce Sanitary Sewer Overflows.
Smaller systems were being videoed on southside of town near Hamby Creek in 2024(Randoph St,
Liberty, and Julian). Smoke testing or video inspection was completed as needed on sanitary sewer
lines. No illicit connections or rerouted connections to storm drains were identified by the city during
2024-2025. No Illicit discharges were reported during this time frame either.
Eight City crew leaders were trained to identify illicit discharges and trained in the reporting process for
these discharges during staff meetings. Possible virtual training of new hires in the future will also be a
way to improve education toward stormwater IDDE problems.

Construction Site Runoff Controls
The City of Thomasville delegates the Construction Site Runoff Controls to NC DEQ.The City of
Thomasville does not have a delegated erosion control program. The city does make sure the plans
approved,that will disturb greater than 1.0 acres of land, apply for and receive an erosion control plan.
The City of Thomasville also has the ability to call NC DEQ to report known sedimentation issues.
Post Construction Site Runoff Controls
The City of Thomasville has a typical NPDES Phase II Post Construction Program.This includes a Post
Construction Ordinance, administrative forms that support it, and a review process. The Post
Construction Program applies to projects that exceed 1 acre of disturbance or have a common plan of
development that will cumulatively exceed 1.0 acres of disturbance. Projects that exceed 24% built-
upon area are considered high density projects, projects that are less than 24% BUA are low density
projects.
High Density Projects are then required to meet the following requirements:
• Treat runoff from the first 1" of rain (the first flush).
• Treated Runoff is to be for 85%TSS removal.
• Discharge treated water at a rate less than or equal to the Predevelopment rate for the 1 year
24 hour storm.
• Discharge treated water between 48-120 hours.
• Stormwater Control Measures must be in easements and must have a recorded operation and
maintenance agreement.
• Compliance with 30'vegetated buffers on perennial and intermittent streams.
Stormwater Control Measures, as well as runoff calculations, are prepared based upon the NC DEQ BMP
Manual and then reviewed by the contracted stormwater engineer, Josh Johnson, P.E.

Low Density projects are required to comply with the stream buffer regulations. Both Low and High
Density Projects are required to comply with the City's Storm Sewer Design Manual which governs
storm drainage design as well as peak runoff rates.
When a project is submitted to the City it goes through the City Planning Department. City Planning staff
determine if the project is more than one acre or not. If the project exceeds 1.0 acres,then a copy of
the plan is sent to Josh Johnson, P.E. with Alley, Williams, Carmen, and King, Inc. AWCK determines if
the project is subject to the Stormwater Ordinance and High Density or Low Density. At that point,
review comments are made about the project and addressed.After approval of the project,the owner is
required to complete an Operation and Maintenance Agreement for the stormwater control measures.
This O&M agreement is then recorded with the register of deeds so that it can be reviewed at a later
point in time.
The City of Thomasville reviewed 19 projects in 2024-25, of which 11 triggered the stormwater
ordinance.The city issued permit approvals for 5 projects that did not cross the one acre disturbance
threshold. Six projects were completed and one SCM was accepted from construction to maintenance.
In FY24-25,two questions about wet pond operation and maintenance were answered and one
abandoned storm pipe was identified and plugged for safety.
The City of Thomasville requires as-builts and annual inspection reports for new stormwater control
measures (SCM) but has had trouble getting annual inspection reports submitted. In the coming year,
the City plans to send a mailing containing information requiring SCM property owners to provide future
inspection reports to the city or face fines and/or assessments.

Pollution Prevention and Good Housekeeping
Pollution Prevention is an overall goal of the City's stormwater management plan and Good
Housekeeping is a key to that goal. Municipalities, in general, conduct many activities that can pose a
threat to water quality. Municipal facilities are a primary potential source of contamination. With good
housekeeping habits,this potential can be reduced or eliminated.The City attempts to minimize
stormwater pollution from municipal operations by complying with best management plans for each
City facility.The BMP's are written into a City Facilities O&M Plan that is intended to reduce or eliminate
stormwater exposure of oil, grease, pesticides, herbicides, fertilizers, sediment, and other materials
used by the City. Each of the City facilities is inspected annually and any issues are noted, written into
the Facility O&M Plan, and discussed with the facility supervisor.
The City of Thomasville operates many different facilities including the following:

City staff who interact with or regularly work near stormwater conveyance systems are trained on
PPGH.Training is combined with illicit discharge detection and elimination training.The PPGH portion of
the training concentrates on good housekeeping functions.This often includes identification of bad
habits that can take place and how to fix the situation to reduce the risk of pollution to stormwater. The
city has one Pesticide applicator in Public Works and two in WWTP who attend annual license renewal
training.
The City of Thomasville sweeps streets annually through the City's Street Department and is estimated
to cover about 530 miles. During FY24-25, 9 tons of debris was collected between March and
November.The debris is roughly 75% inorganic and 25%organic. The number of tons went down for at
least two reasons; less trash and better measurement techniques. This number shows program success.
The Fall/Winter Leaf Pick up Program collects leaves deposited along the curb from November through
January.
The City of Thomasville normally puts out road salt and alternatives to road salt. In 2024-2025,weather
conditions did not require road salt or brine applications. As another Good Housekeeping measure,the
City recycled 900 gallons of oil through the heating of the Fleet Services Facility.

The City of Thomasville Street Crews clean culvert pipes and drainage ditches on an as needed basis.
Culvert pipes are cleaned by jet truck. Ditches are maintained with a combination of backhoe operation
and manual labor. Storm drains and grated inlets are cleaned as needed by hand before and after large
precipitation events.
Maintaining pet waste stations keeps excess nutrients from entering waterways. The City does not have
any pet waste stations or dog parks currently. A dog park with a pet waste station is under construction
at Myers Park.
Impaired Waters and Total Maximum Daily Loads (TMDL)
The City of Thomasville has significant issues with impaired waters and the City drains to two different
TMDL protected waters.The impaired streams are Rich Fork Creek, Hamby Creek, North Hamby Creek
and Hunts Fork.The TMDL's are for Turbidity in High Rock Lake and for Fecal Coliform in Rich Fork Creek
and Hamby Creek.The TMDL for Rich Fork and Hamby Creek's specifically lists Sanitary Sewer Overflows
as a source of fecal coliform in the streams and the City has dedicated its resources to limiting SSO's
from the Collection System in order to improve the water quality within these streams (see above
section on IDDE and the future Inflow/Infiltration/Exfiltration Report). Some details about the impaired
streams are included below:
• Rich Fork Creek (12-119-7b) is impaired for Fecal Coliform and for Ecological and Biological
Integrity of the Fish Community. Rich Fork Creek has significant water quality problems as it
drains High Point as well as Thomasville. The City of Thomasville is working to comply with the
TMDL by improving the collection system within Thomasville.
• Hunts Fork(12-119-7-3) is impaired for Ecological and Biological Integrity of the Benthic
Community. Hunts Fork is directly upstream of Rich Fork Creek and the City is working to
improve the collection system within this watershed.
• Hamby Creek (12-119-7-4a) is impaired for Fecal Coliform and for Ecological and Biological
Integrity of the Fish Community. Hamby Creek has significant water quality problems as it drains
High Point as well as Thomasville.The City of Thomasville is working to comply with the TMDL
by improving the collection system within Thomasville.
• North Hamby Creek (12-119-7-4-1) is impaired for Ecological and Biological Integrity of the
Benthic Community. North Hamby Creek is directly upstream of Hamby Creek and the City is
working to improve the collection system within this watershed.
High Rock Lake Rules
The City of Thomasville is within the High Rock Lake Watershed. High Rock Lake is impaired for elevated
levels of turbidity, chlorophyll a, and pH.The chlorophyll a and pH impairments are primarily associated
with excess algal growth, which is caused by elevated nutrient loading to the lake (primarily nitrogen
Page 13 of 15

City of Thomasville Stormwater Annual Report
2024—2025
and phosphorous).The turbidity impairment is also related to the algal growth within the lake but is
primarily due to upstream sedimentation to the lake.The Lake has a drainage area of 3,974 square
miles. Although, a portion of that watershed (367 square miles) is within the Kerr Lake watershed.The
dam for High Rock Lake is about 25 miles from the center of Thomasville and Thomasville is one of
several urbanized centers within the watershed.The other urbanized areas include Winston-Salem,
Salisbury, High Point, and Lexington.

NC DEQ has been working on potential solutions to improve water quality within High Rock Lake for
several years and expects to develop the Nutrient Management Strategy. High Rock Lake is listed as the
number one priority on the State of North Carolina's Nutrient Development Criteria Plan but is currently
on hold due to NC DEQ staffing restrictions. The City of Thomasville should be heavily involved in the
stakeholder process and should evaluate how it's improvements to its Collection System may already be
contributing to improving water quality within downstream waters. Technical advisory group (TAG)
mailings request input and encourage collaboration.

City of Thomasville Stormwater Annual Report
2024—2025
Stormwater Funding
The City of Thomasville funds it's Stormwater Programs through a Stormwater Fee.The City collects a
flat fee of$1/month from utility users. The City uses this fee to pay for its Water Quality Programs
including its NPDES Phase II and Inflow/Infiltration/Exfiltration Program and/or studies.The City's
Stormwater Budget for the 2024-2025 Fiscal Year is$109,380.00 and the City plans to use accrued
stormwater balance for future stormwater specific projects.
In the future,the stormwater budget may need to increase to fund additional improvements.These
increases may be offset by converting the current flat fee into an Existing Residential Unit (ERU)style
fee.The ERU is based on an impervious area per property calculation and will be a more equitable
distribution of stormwater costs than the flat fee is. However,the ERU will have a substantially higher
startup and maintenance costs than the current fee has.
The Future of Stormwater
Stormwater, and Water Quality in particular, is continually evolving through research and field
investigations,which influences regulations. The City of Thomasville is already involved in NPDES Phase
II and Nutrient Sensitive Waters. Within the next decade the City needs to plan for further regulation of
these issues as well as several other outstanding issues.As stormwater information and regulation
continue to evolve,the City should expect to see additional regulations, costs, and improvements within
their stormwater program.
