1.3 Jurisdictional and MS4 Service Area
The current jurisdictional and MS4 service area for the City is 60.042 square
miles. The City has 2.26 square miles of extra territorial jurisdiction (ETJ). No
additional ETJ is expected to be granted by the county.
1.4 MS4 Conveyance System
The City has completed a multi -year service area wide inventory and mapping of
its MS4 conveyance system. In addition, in January 2007, the City's Stormwater
Department hired a full time GIS Technician. This position works to constantly
update system maps, map new infrastructure, and collect additional data such as
Concord Comprehensive Stormwater 2 January 2010
Management Program Report

dry weather flows, infrastructure condition, illicit discharges, etc. The City has
surveyed and mapped approximately 16,117 pipes totaling over 222 miles of pipe,
174 miles of ditches, and 9923 stormwater structures including inlets, junction
boxes, etc. The percentage of infrastructure surveyed is estimated at
approximately 95%. The City's internal performance measures strive for the
survey and inspection of>25% of the system annually.
An important part of the inventory is the evaluation of the condition of these
structures and pipes by field crews. Any maintenance needs are documented in
work orders and automatically assigned to stormwater crews. In addition, the
work order information is permanently linked to asset id numbers in the GIS
database. This allows staff to select a pipe, ditch, or structure and view its
maintenance history.
The City performs routine maintenance and repairs on the MS4 in the public
ROW on an as -needed basis.
1.5 Land Use Composition Estimates
The Land Use Composition for the City is estimated to be 52 percent - residential,
23 percent - commercial, 23 percent - industrial, and 2 percent - open space.
1.6 Total Maximum Daily Load (TMDL) Identification
There are no TMDL designated streams within the City's MS4 service area.

3.0 EXISTING WATER QUALITY PROGRAMS
3.1 Local Programs
The City is a participant in the Water Supply Watershed Protection Program and
has the necessary controls in place to meet these regulations. Lake Concord,
which lies within the City's MS4 service area, is a WS-IV CA classified
watershed. The measures outlined in the Concord Development Ordinance
(CDO) include limitations on development, employment of Best Management
Practices (BMPs) and riparian buffers, and prohibited uses in the overlay districts.
Development regulations include a maximum of two units per acre and a
maximum built -upon area of24 percent.
A stream buffer measure is included in the Class I Buffer (formerly River/Stream
Overlay District) section of the CDO. The measure calls for "buffers to be
retained in their natural vegetated, revegetated, or reforested state". The stream
buffers are to be established on both sides of perennial streams indicated as a solid
blue line on the most recent 7.5-minute United States Geological Survey (USGS)
topographic maps. The width of the buffer, measured perpendicular from the
average annual stream bank, includes a distance 50 feet plus four times the
average percent slope of the area adjacent to the stream. The average slope is
calculated over a distance of 250 feet perpendicular to the center of the stream.
The maximum required buffer width may not exceed 120 feet from the edge of
the stream. There is a 20 foot no built upon area adjacent to the buffer. in
addition, the CDO requires stream buffers on both sides of all intermittent streams
shown on either USGS or NRCS Soil Survey maps. This intermittent buffer is 30
feet undisturbed plus an additional 10 foot vegetated buffer. The vegetated buffer
can be graded but must be re -vegetated with no impervious area allowed. No
construction activity is allowed within the undisturbed buffer.
Stormwater control regulations are summarized in the Environmental Controls
Regulations section of the CDO. The policy states that all high -density proposed
development that will exceed 20,000 square feet of built -upon area or disturb
more than one acre are required to mitigate the impacts of the design storm
rainfall. High density developments requiring stormwater BMPs to mitigate their
impacts must construct structural BMPs in accordance with the latest release of
the State's BMP Design Manual to remove 85% of total suspended solids. The
post development runoff rate for the 1- and 10-year design storm conditions must
also be mitigated to pre -development levels. Low density developments are
required to implement non structural BMPs such as grassed swales. Low density
developments also require deed restrictions and an allotment of impervious area
to each subdivided lot. Certain low density development that contain pockets of
higher densities that discharge directly into receiving streams are required to
mitigate their impact to the receiving stream.
Concord Comprehensive Stormwater 5 January 2010
Management Program Report

Developments that could cause fecal coliform issues are required to mitigate their
exposure to the maximum extent practical.
The City is currently completing an application for the Concord Regional Airport
(JQF) under general permit NCG 150000.
The City has an official agreement with Cabarrus County to facilitate the
construction site erosion and sediment control program within the City of
Concord.
3.2 State Programs
Due to the formal agreement with Cabarrus County for erosion control program
administration, the City obtains all erosion control permits for city projects
directly from NCDENR.
Concord currently holds a NPDES Phase II stormwater discharge permit.

Legal Agreements
Effective January 1, 1998, the City entered in agreement by resolution for services
of soil erosion and sedimentation control from Cabarrus County. The City
adopted the Cabarrus County Soil Erosion and Sedimentation Control Ordinance
on January 8, 1998. This resolution directs Cabarrus County to provide personnel
to enforce the above -mentioned ordinance within the corporate limits of Concord.
A copy of this resolution is presented in Appendix A.
Concord Comprehensive Stormwater 10 January 2010
Management Program Report

7.0 STORMWATER MANAGEMENT PLAN
7.1 Public Education and Outreach on Storm Water Impacts
7.1.1 Target Pollutant Sources
Several pollutant sources have been identified for the concentration of
education efforts. These pollutant sources are categorized as household
wastes (oil, detergents, paints, and solvents), commercial waste, land
application pollutants (fertilizers, pesticides, and herbicides), and
organic/land derived pollutants (leaves, grass, sediment, and fecal
coliform). These sources have been identified for their frequent use or
appearance in the lives of the identified target audience. These sources are
also highly controllable with the education of citizens on proper waste
disposal procedures, knowledge on the use and function of a storm sewer
system, and the recommendation of non -threatening products and
procedures like biodegradable products or composting.
7.1.2 Target Audience
The City targets a diverse audience to incorporate in many activities of the
stormwater education program. it is necessary to involve all ages of
citizens and include people from all sectors, residential, educational,
municipal, commercial, institutional, and industrial. The identified target
audiences for the City.include: K-12 students (emphasis on elementary
grades), youth civic organizations, homeowners and homeowner
associations, real estate and commercial developers, small business
owners, commercial business operators, municipal employees, and
industry. The City is also making an effort to accommodate non-English
speaking residents through bi-lingual communication materials.
7.1.3 Outreach Program
In 2008, the City implemented a Storm Drain Marking Program. There
have been several civic and neighborhood groups volunteer to mark storm
drains throughout the City. Table 2 shows the progress of the program.

The City participates in NC Big Sweep. Big Sweep is a state wide
organization committed to cleaning up North Carolina watersheds. Big
Sweep Cleanups serve to bring; community volunteers together to remove
trash and debris from local waterways. Each year, City of Concord
employees and citizens work together to clean up local streams. Recently,
Big Sweep events were led at Lake Fisher, a water supply, and sections of
Three Mile Branch and Irish Buffalo Creek in Concord.
The City also participates in Litter Sweep. This program connects
volunteers together to beautify our roadsides, protect water quality and the
health of the environment by removing litter. The City of Concord
conducts the Litter Sweep program twice each year, once in the spring and
once in the fall. During each Litter Sweep, City employees and
community volunteers clean come together to clean roadsides throughout
the City. City departments are required to participate and we encourage
recognized neighborhoods to participate by assuming responsibility for
their streets. The City rewards employees for the most bags collected and
the most unusual litter and neighborhoods for the most bags collected,
Concord Comprehensive Stormwater 12 January 2010
Management Program Report

The City is currently working on implementing an Adopt a Stream
Program.
The City of Concord's most successful educational program is its civic
education program. Stormwater and water quality has been integrated into
this already successful program. This program includes city employees
going into third grade classes and introducing water quality topics to
students. These topics are later reinforced when the students visit City
facilities for a hands on tour of -City operations.
Stormwater staff is also readily available to visit and speak with home
owners groups, businesses, civic groups, etc. to discuss topics such as
water quality, flooding, and the proper use and disposal of household
chemicals.
The City of Concord holds an executive committee position on the
Regional Stormwater Partnership, The Regional Stormwater Partnership
is a consortium of seventeen city and county governments in the greater
Charlotte, NC region that are working together to promote good
stormwater practices at both the local and regional levels. The Partnership
was formally established in early 2008 with funding from a Clean Water
Management Trust Fund grant and local match funds from the
participating communities. Projects have included the construction of
regional demonstration BMPs, the development and printing of
stormwater educational information, purchase of adopt -a -stream
equipment, and Hispanic focus groups to determine the best way to
educate the Hispanic population on storrnwater issues. The partnership
also pools funds for TV and radio ads in the Charlotte region to broadcast
a clean water message.
7.1.4 Evaluation
The public education measure is evaluated several different ways. The
number of educational events, estimated number of educational
participants, bags of trash removed, number of educational information
distributed, number of storm drain markers installed, number of radio and
TV ads are all tracked to evaluate the outreach component.
Concord Comprehensive Stormwater 1 a January 2010
Management Program Report

7.2 Public involvement and Participation
7.2.1 Stormwater Management Advisory Committee
The Stormwater Management Advisory Committee (SMAC) is a 9
member committee appointed by City Council. These 9 seats are divided
equally among three groups. The membership includes three members
from city -recognized neighborhood or homeowners associations; three
members from businesses or not -for -profit organizations; and three
members with engineering or scientific training, vocational experience, or
a strong personal interest in environmental management or preservation.
All members shall reside within the city limits.
Members of the SMAC are appointed to a three year term and may serve
up to two full terms.
The SMAC holds regularly scheduled public meetings quarterly. The
committee frequently meets more often when discussion of pressing
stormwater matters is required. All meeting dates are advertised to the
public.
The SMAC is tasked with discussing stormwater issues including funding
and service levels and ordinance and code revisions. The committee
makes official recommendations to City Council and the Planning and
Zoning Board on stormwater issues.
7.2.2 Volunteer Participation Programs
The City of Concord sponsors a Big Sweep event each year. Events
typically involve corporate sponsorship and are held to clean up area
streams and water supply lakes. The City also sponsors a communitywide
litter sweep twice a year. this program brings businesses, homeowners,
and city employees together as they adopt street segments to pick up
littler. Participation is very high and prizes are awarded to the group
collecting the most trash.
The City also has a very active storm drain marking program. This
program uses volunteers to glue "Dump No Waste" markers on storm
drains to encourage the proper disposal of waste and yard debris.
Through the Regional Stormwater Partnership and a Clean Water
Management Trust Fund grant, the City has begun an adopt -a -stream
program. The grant secured funding for materials such as litter grabbers,
waders, gloves, and bags. Staff is currently working to formalize and
expand the program citywide.
The Regional Stormwater Partnership also hosted two Hispanic focus
groups. The goal of the meetings was to determine the most effective
Concord Comprehensive Stormwater 14 January 2010
Management Program Report

means of relaying the water quality message to the Hispanic community.
The focus groups were very successful and the results have changed the
types of materials the partnership will ultimately produce.
7.2.3 Evaluation
'fhe evaluation of this measure is tracked many ways. For litter sweep and
Big Sweep, staff tracks the amount of people participating and the
numbers of bags of trash collected. The evaluation off the advisory
committee is tracked by the level of attendance and participation of the
members and the public. The storm drain marking program is tracked by
the numbers of volunteer groups and the number of markers places.
7.3 Illicit Discharge Detection and Elimination
7.3.1 Storm Sewer System Map
The City has completed its outfall assessment project using contract
engineers and surveyors. Structures, such as catch basins, drop inlets,
manholes; pipe outfalls, etc were surveyed for GPS coordinates and tagged
with their condition, material, structure depth, pipe depth, .etc. Pipes were
tagged for many of the same characteristics but also included descriptions
on their entrance and exit features as well as their diameter and geometry.
This inventory included systems existing or beginning only in the public
ROW and followed the systems to outfalls on receiving streams. The City
Stormwater Department GIS Technical frequently updates data points and
attributes to assure the accuracy of the Storm Sewer System Map.
The attribute data and coordinates are compiled into ArcView0 shape files
for use by various City staff. The Concord Development Ordinance
requires that owners of new development submit as -built drawings of their
storm sewer system for easy updating with the master shape file and
database.
7.3.2 Regulatory Mechanism
City Code Chapter 60 Article IV defines and prohibits non-stormwater
illicit discharges from being released into the City"s MS4 or receiving
waters, and allows for the inspection, and elimination of these discharges.
This article also established the penalty for violations of the Illicit
Discharge Ordinance.
Concord Comprehensive stormwater 15 January 2010
Management Program Report

7.3.3 Enforcement
Several public educational items have been distributed that educate the
public on illicit discharges and illicit connections. These items are
generally a part of every stormwater educational event. Fines have been
established as well as a mechanism for the City to resolve the illicit
discharge or connections and seek reimbursement from the violator. To
assist in timely and successful enforcement, several members of the
stormwater department are sworn code enforcement officers and handle
most stormwater ordinance violations internally.
7.3.4 Detection and Elimination
Stormwater staff attempt to locate facilities, homes, or properties that are
unlawfully discharging into the City's MS4. City Code grants stormwater
staff the right to enter a private property and to further investigate,
monitor, test, or sample discharges from the property, in order to confirm
a violation. In the event that illegal discharge is detected the owner will
be notified of the detected illegal discharge with remedial action to be
taken and a time frame to complete.
Priority areas have been identified for increased illicit discharge and illicit
connection investigation. The priority areas were established through an
analysis involving overlaying datasets like NPDES wastewater discharges,
industrial land use density, and older development density to amass
probable areas. The City also utilizes its Call Center to host a 24-hour, 7-
day environmental hotline. This hotline fields illegal discharge/dumping
and spill reports.
Stormwater staff also works closely with the Wastewater Department's
fats, oils, and grease program. The disposal and handling of cooking
grease is of great importance to both departments. Both educational
programs highlight the proper disposal of these items.
The City uses several methods and tools in determining a source of an
illegal discharge. The storm sewer inventory and map serves as the most
valuable tool for locating illegal discharges. The map allows City staff to
back track discharges along storm sewer lines and through structures to
the probable cause of the illegal discharge or connection. The City also
uses dry weather screening and video pipe inspection as reliable means of
linking sources with discharges.
City fire safety staff that perform annual and biannual building code
inspections are also trained to identify and report illicit connections and
illicit potential discharges.
Concord Comprehensive Stormwater 16 January 2010
Management Program Report

Evaluation
The amount (in feet) and percentage of the total storm sewer system
surveyed by video inspection; the number and percentage of dry weather
outfall inspections; and the number of illegal discharges detected and
eliminated are tracked to evaluate the program.
The City is currently developing a private property stormwater grant
program. This program will use stormwater utility fees to assist property
owners with private property stormwater issues including illicit
connections and discharges. Water quality issues are high on the grant
priority list.
7.3.5 Non-Stormwater Discharges
The Stormwater Ordinance lists several non-stormwater discharges that
when properly managed to ensure that no potential pollutants are present,
can be discharged into the MS4 and waters of Concord. They include:
a. Filter backwash and draining associated with raw water intake
screening and filtering devices;
b. Potable water line flushing and hydrostatic testing water
associated with utility operations;
c. Flushing and cleaning of stormwater conveyances with
unmodified potable water;
d. Uncontaminated pumped groundwater and other discharges
from potable water sources such as water line leaks, draining for
pipes for repairs, and emptying of potable water storage tanks;
e. Landscape irrigation and lawn watering water;
f. Diverted stream flows;
g. Uncontaminated rising groundwater;
h. Groundwater infiltration to the storm drain system;
i. Uncontaminated groundwater from foundation and footing
drains,
j. Uncontaminated groundwater from crawl space pumps;
k. Residential or commercial air conditioning condensation;
I. Uncontaminated water from roof drains;
in. Wash water from the cleaning of the exterior of buildings,
including gutters, provided that the discharge does not pose an
environmental or health threat;
n. Uncontaminated groundwater from springs;
o. Individual residential and occasional non-commercial car
washing;
p. Water from riparian habitats and wetlands;
q. Discharges from the pumping or draining of natural
watercourses or waterbodies;
r. Filter backwash and draining associated with swimming pools
provided that water quality is not significantly impacted:;
Concord Comprehensive Stormwater 17 January 2010
Management Program Report

s. Street wash water,
t. Flows from fire fighting;
u. Discharges associated with emergency removal and treatment
activities, for hazardous materials, authorized by the federal, state,
or local government on -scene coordinator; and
v. Other non-stormwater discharges for which a valid NPDES
discharge permit, waiver, or waste discharge order has been
approved and issued by the State of North Carolina under the
authority of the Federal Environmental Protection Agency,
provided that:
1. The discharger is in full compliance with all
requirements of the permit, waiver, or order and other
applicable laws and regulations;
2. Written notification of such permitted discharge has been
tiled with the Stormwater administrator, in a form
acceptable to the stormwater administrator; and
I Discharges to the municipal separate storm sewer system
have been authorized by the stormwater administrator.
7.3.6 Other Incidental Stormwater Discharges
Discharges from uncontaminated roof drains and occasional non-
commercial car washing are accepted non-stormwater discharges in the
Stormwater Ordinance. The City will control the frequency and/or
location to sensitive water 'bodies of these activities and implement or
require BMPs where necessary.
7.3.8 Outreach
Several public education and good housekeeping elements are dedicated to
educating citizens and employees about the environmental impacts of
illicit connections. Stormwater staff periodically trains all public works
Feld crews in illicit discharge detection. To date, several discharges have
been reported by field personnel other than stormwater staff.
7.3.9 Staff Training
Through the Stormwater good housekeeping program, all public works
field staff is trained to identify illicit discharges. Trainings are conducted
periodically based upon employee turnover and new hires.
7.3.10 Evaluation
The City evaluates the success of illicit discharge detection by comparing
the percentage of storm drain surveyed annually to pervious years. 100%
of illegal discharges detected are pursued for corrective actions.
Concord Comprehensive Stormwater 18 January 2010
Management Program Report

7.4 Construction Site Stormwater Runoff Control
The State delegated Cabarrus County Soil Erosion and Sediment Control Division
fully complies with this NPDES Phase 11 measure. The Concord Development
Ordinance requires a County erosion control permit prior to plan approval, if
applicable. Violations of a County erosion control permit are also violations of
the Stormwater Ordinance. City staff periodically makes site visits to
developments under construction to assure compliance with approved erosion
control plans.
In addition, stormwater staff participates in the Cabarrus County Watershed
Improvement Commission. This appointed committee hears reports from
environmental staff members from several Cities and the County. This
Committee is informed of all erosion control violations and hears appeals to
erosion control violations and fine issued by the County.
7.5 Post -Construction Storm Water Management in New Development and
Redevelopment
7.5.1 Use of Non -Structural BMPs
The City currently regulates land development and protection with its
Development Ordinance. Staff reviews and comments on all development
ordinance changes to identify potential conflict with permit requirements.
Staff makes recommendations to the City's Planning and Zoning
Committee for modifications of the current regulations where necessary.
Staff also reviews all requests for annexation.
As part of the post construction controls, the stormwater staff administers
its own site plan review process. Developments required by the
Stormwater Ordinance to submit a plan are reviewed for compliance and
performance. This opportunity allows for stormwater staff to identify
potential problems to developers. Notable areas of suggestion include the
minimization of. the disturbance to soils and vegetation, impervious
areas, and directly connected impervious areas.
In addition, annual inspection reports are required for all BMPs.
Stormwater staff reviews these inspections and makes site visits if
necessary. This assures the proper operation and maintenance of the
BMP.
7.5.2 Use of Structural BMPs
The City Stormwater Ordinance requires the use of the DWQ BMP
Manual. This manual provides a menu of approved structural BMPs for
developers and owners to use for the control and treatment of Stormwater
on their properties. This manual includes a variety of BMPs satisfying
storage, filtration, and infiltration practices or combinations thereof.
Concord Comprehensive Stormwater 19 January 2010
Management Program Report

7.5.3 Regulatory Mechanism
City Ordinances define the process of requiring stormwater quality
controls and the enforcement BMP maintenance. Fines have been
established as well as a mechanism for the City to resolve BMP operation
and maintenance issues. To assist in timely and successful enforcement,
several members of the stormwater department are sworn code
enforcement officers and handle most stormwater ordinance violations
internally.
7.5.4 Operation and Maintenance
City Ordinance requires owners to properly operate and maintain their
stormwater BMPs. Before the completion of a development project, a
Professional Engineer must certify BMP construction and as-builts for the
BMP. Before a final permit is issued, the owner must sign and record a
stormwater operation and maintenance plan and agreement. This
agreement provided operations and maintenance instructions specific to
each development site. The agreement also established a BMP easement
around the BMP and an access easement that allows the City to inspect the
BMP and conduct maintenance ourselves, if ever needed. If maintenance
is required or work is not performed in a satisfactory manner, the City
reserves the right to enter the property after sufficient notice and complete
or correct the maintenance work. The work performed by the City will be
the financial responsibility of the owner. if the owner is delinquent to
his/her financial responsibility the City may impose liens against the
property. All easements and the signed inspection and maintenance
agreement are recorded with the Cabarrus County Register of Deeds.
Annual inspection reports are required for all BMPs. Stormwater staff
reviews these inspections and makes site visits if necessary. This assures
the proper operation and maintenance of the BMP.
7.5.5 Structural BMPs Types
The City of Concord used the DWQ Stormwater BMP Manual for all of
its structural BMP requirements. The City has seen the development of
wet ponds, sand filters, bio-retention cells, dry detention (in combination),
filter strips, and grass swales. BMPs relying on infiltration have been
limited due to soil types and conditions in the region. Most large scale
development sites typically utilize wet ponds to accommodate the local
requirement to detain the peak for the 10 year storm.
7.5.6 Natural Resource Protection
The Concord Development Ordinance (CDO) requires many measures to
protect both critical habitat and natural resource areas. Class 1 streams
(USGS Perennial) require a large undisturbed buffer between 50 and 120
feet from the top of the stream bank. An additional 20 foot vegetated
Concord Comprehensive Stormwater 20 January 2010
Management Program Report

buffer is required beyond that. In addition, Class2 streams (USGS and
NRSC intermittent) require and 30 foot undisturbed buffer, on each side,
then an additional 10 foot vegetated buffer beyond that.
In -line water impoundments, both natural and manmade, are required to
have the same buffer as the class of stream leaving the impoundment.
Special buffers and measures are in place in the small water supply
watershed area.
7.5.7 Open Space Preservation
The Concord Development Ordinance requires open space of all new
development. We encourage open space to be place between receiving
streams and developing lots to create a larger buffer and to restrict
individual owners from being able to disrupt the function of the buffer.
Commercial and industrial sites are also required to provide open space. It
is strongly encouraged that this open space be preserved area that will not
be graded or disturbed during development.
The City has also worked closely with the County on zoning issues. It is
policy to keep zoning consistent during annexation. Many sections of the
County, inside Concords service area boundary, have been rezoned to
allow fewer houses be acre and even restrict the availability of municipal
water and sewer.
7.5.8 Tree Preservation
The City of Concord is currently working to establish a tree save
ordinance. While individual developments are reviewed to discourage
mass grading, the tree save ordinance will require specific tree
preservation techniques. The City is currently reviewing a draft tree
preservation ordinance.
The City requires street trees to be planted in conjunction with new
development. In addition, the CDO requires a variety of tree plantings in
the parking lot standards. A shade tree must be planted within 60 feet of
all parking spaces. These trees will eventually provide shade to help cool
the parking lot. Additional ornamental trees and scrubs are also required.
Downtown Concord has many large old trees along the historic district
corridor. The City monitors the health of these trees and restricts their
cutting. If deemed unhealthy or unsafe, the City participated in the tree's
removal and plants a new tree back. Trees planted by the City in public
areas are species that are know to thrive in the region.
7.5.9 Redevelopment
Concord Comprehensive Stormwater 21 January 2010
Management Program Report

The City also provided incentive, through economic development grants,
for the re -development of existing properties. The last few years have
seen the re -development of several old textile mills into commercial,
industrial, and office space. The re -developments were accomplished with
the help of these development grants.
7.5.10 Development Along Existing Infrastructure
The City recently worked with Cabarrus County on several land use plans.
The outcome of these plans is to limit the further extension of new potable
water and sewer lines and to direct development to areas with existing
infrastructure.
7.5.11 Mixed -Use Development
The City has several highly successful mixed use developments. The
development ordinance allows for mixed use development. The
development ordinance also required a transit stop shelter at certain large,
traffic generating commercial developments. This requirement assures
that there will be transit access and availability to the development.
7.5.12 Street Design
The CDO allows for variance to certain roadway design standards. If
approved, roads can be designed to the rolling classification if the existing
site topography would require mass or excess grading if meeting level
terrain. City residential streets are categorized into two groups. Local
residential streets are generally streets that serve single family residential
lots. These streets can be as narrow as 20 feet (10 foot lanes). 20 feet
minimum is required for fire access. Collector roads are typically the
main entrance road and connecting roads within a subdivision. These
roads are typically wider due to the need for turning movements, higher
traffic volumes, and sometimes on street parking. The City determines the
classification of the road prior to design.
A Low impact development ordinance is currently being reviews for
approval. This ordinance will encourage shared driveways.. large lots,
alternatives to curb and gutter, open space, additional pedestrian
connectivity, etc.
7.5.13 Green Infrastructure and Design
The City of Concord is currently researching alternatives to traditional
paving for curb and gutter and sidewalk. The CDO allows the use of
pervious concrete outside of the road right-of-way. Pervious concrete has
been used on numerous greenway projects.
Concord Comprehensive Stormwater 22 January 2010
Management Program Report

The City extensively used brine solution to treat roadways prior to winter
storm events. Before brine, the City would use a straight salt and sand
mixture during the storm. The brine allows for a lower concentration of
salt to be applied in advance of the storm. This typically eliminates the
need for additional salt and slag during the storm, causing a lesser impact
to surrounding water quality.
7.5.14 Reduced Parking Requirements
The City has very specific and realistic parking requirements based upon
the use of the property. Variances can be requested to change the
requirements. The City of Concord owns a parking deck downtown. The
deck is open to public parking which discourages the need for additional
private parking spaces downtown. There are currently no incentives
available to reduce parking requirement.
7.5.15 Stormwater From Parking Lots
The CDO requires landscaped parking islands, shade and ornamental
trees, and scrubs. Also required are measures to break up multiple
consecutive rows of parking and landscaped street; building, and buffer
yards. These landscaped areas allow for stormwater infiltration and
reduce the overall impervious footprint of the site. Rain gardens are also
permitted in the parking lot islands.
7.5.16 Green Infrastructure Practices
The City of Concord allows and encourages the use of cisterns and rain
barrels. As a water conservation community, the City even sells rain
barrels at a wholesale discount to citizens. City rules also allow the use of
stormwater wet ponds for irrigation purposes.
The City holds regularly scheduled pre -submittal review meetings. At
these meeting, engineers, architects, owners, and city staff discuss broad
topics effecting the development. These topics often include stormwater
management, overall site water quality, erosion control, and BMP
operation and maintenance.
The City defers to the County Health Department and the County Building
Standards Department to determine suitable uses for harvested rainwater.
There is currently no "pay -in -lieu" available for stormwater requirements.
Concord Comprehensive Stormwater 23 January 2010
Management Program Report

7.6 Pollution Prevention/Good Housekeeping for Municipal Operations
7.6.1 Affected Operations
Municipal operations impacted by this program include electric, water
resources, wastewater, building and grounds, engineering, environmental,
fleet, transportation, parks and recreation, police, and fire and life safety.
The Coddle Creek WTP's NPDES wastewater discharge permit number is
NC0083 l 19. A general permit if pending for Concord Regional Airport.
7.6.2 Training
The Stormwater staff performs in-house training of the City's employees
on pollution prevention and better operations management. This training
is provided on an annual basis and on demand for new hires. Existing
material from other public education program are used along with a Storm
Watch video.
Stormwater staff also holds trainings periodically at monthly safety
meetings. Past topics include spill prevention, disposal of yard waste,
proper use of household chemicals, chemical storage, spill cleanup, illicit
discharge detection, vehicle fueling, vehicle washing, and the proper
disposal of waste oil and other waste products.
7.6.3 Maintenance and Inspections
The Stormwater Staff reviews the procedures and methods of the
Buildings and Grounds Services for pollution prevention ideas,
specifically the proper use of fertilizers and pesticides on City properties.
The City operates several parks with athletic fields among other properties
that may require fertilization. The proper application of fertilizers may
contribute to a reduction in pollution to area streams. Reduced mowing
around waterways on the City properties encourages growth of the riparian
habitat where it may have been destroyed.
7.6.4 Vehicular Operations
The Alfred M. Brown Operations Center is the control facility for many of
the City's municipal services. This facility host the fleet management
staff and provides storage for municipal equipment and materials. An
audit of the site and the services provided at his location will lead to the
development of a pollution prevention plan. Some areas of review will
include the practices of the fleet repair and maintenance staff, including
the storage of the vehicles in the parking lot itself. The pollution plan will
recommend practices to ensure the proper disposal of vehicle parts and
used materials and a BMP for filtering out vehicle residues from parking
lot runoff.
Concord Comprehensive Stormwater 24 January 2010
Management Program Report

As part of the pollution prevention plan for. the Brown Center, the
Stormwater Staff will review current vehicle washing procedures for
potential improvements in pollution control. It may be necessary to
construct and implement protocol 'for a vehicle pre -wash facility that will
collect used wash water for pretreatment or disposal into the City's
sanitary sewer.
7.6.5 Waste Disposal
Cabarrus County operates several waste disposal facilities such as
landfills, a household hazardous waste facility, recycling convienience
centers, and used battery drops. To ensure the proper disposal of certain
wastes, the City trains City employees in the location of these facilities
and their waste acceptance practices.
