Chapter 8. Post Construction Storm Water Regulations

155.801. General Provisions [formerly § 154]

A. TITLE. These regulations shall be officially
known as the “Post Construction Storm
Water Ordinance” and is commonly known
as and referred to in this Title as the “PCO”.
[formerly known as § 154.001]
B. AUTHORITY. The Town is authorized to
adopt these regulations pursuant to North
Carolina law, including but not limited to
Article 14, Section 5 of the Constitution of
North Carolina; North Carolina General
Statutes 143-214.7 and rules promulgated
by the Environmental Management
Commission; Session Law 2004-163;
Chapter 160A, §§ 174, 185. [formerly
known as § 154.002]
C. FINDINGS. It is hereby determined that:
Development and redevelopment alter the
hydrologic response of local watersheds
and increase storm water runoff rates and
volumes, flooding, soil erosion, stream
channel erosion, non-point source
pollution, and sediment transport and
deposition, as well as reduce groundwater
recharge; these changes in storm water
runoff contribute to increased quantities of
water-borne pollutants and alterations in
hydrology which are harmful to public
health and safety as well as to the natural
environment; and these effects can be
managed and minimized by applying
proper design and well planned controls to
manage storm water runoff from
development sites. Further, the Federal
Water Pollution Control Act of 1972 (“Clean Water Act”) and Federal Phase II Storm Water Rules
promulgated under it, as well as rules of the North Carolina Environmental Management Commission
promulgated in response to federal Phase II requirements, compel certain urbanized areas, including the
Town of Matthews (the “Town”), to adopt the minimum storm water controls such as those included in the
PCO. Therefore, the Town establishes this set of water quality and quantity regulations to meet the
requirements of state and federal law regarding control of storm water runoff a nd discharge. [formerly
known as § 154.003]
D. PURPOSE.
1. GENERAL. The purpose of these regulations is to protect, maintain and enhance the public health,
safety, environment and general welfare by establishing minimum requirements and procedures to
control the adverse effects of increased post construction storm water runoff and non-point source
pollution associated with new development and redevelopment. It has been determined that proper
management of construction-related and post construction storm water runoff will minimize damage
to public and private property and infrastructure, safeguard the public health, safety, and general
welfare, and protect water and aquatic resources.

2. SPECIFIC. These regulations seek to meet its general purpose through the following specific
objectives and means:
a. Establishing decision-making processes for development that protect the integrity of
watersheds and preserve the health of water resources;
b. Minimizing changes to the predevelopment hydrologic response for new development and
redevelopment in their post construction state in accordance with the requirements of these
regulations for the applicable design storm in order to reduce flooding, streambank erosion,
and non-point and point source pollution, as well as to maintain the integrity of stream
channels, aquatic habitats and healthy stream temperatures;
c. Establishing minimum post construction storm water management standards and design
criteria for the regulation and control of storm water runoff quantity and quality;
d. Establishing design and review criteria for the construction, function, and use of structural
storm water control facilities that may be used to meet the minimum post construction
storm water management standards;
e. Establishing criteria for the use of better management and site design practices, such as the
preservation of greenspace and other conservation areas;
f. Establishing provisions for the long-term responsibility for and maintenance of structural
and nonstructural storm water best management practices (BMPs) to ensure that they
continue to function as designed, are maintained appropriately, and pose minimum risk to
public safety;
g. Establishing administrative procedures for the submission, review, approval and
disapproval of storm water management plans, for the inspection of approved projects, and
to assure appropriate long-term maintenance; and
h. Coordinating post construction storm water control provisions to be consistent with other
standards within this Title, including such areas as storm water detention, landscaping and
tree canopy, open space, and nonconforming improvements. (Am. Ord. 2025A, passed 6-
9-14) [formerly known as § 154.004]

TOWN OF MATTHEWS UNIFIED DEVELOPMENT ORDINANCE

Page 8 - 5
decisions about storm water management permits and about the design, implementation and
performance of structural and non-structural storm water BMPs. The Design Manual includes a list
of acceptable storm water treatment practices, including the specific design criteria for each storm
water practice. Storm water treatment practices that are designed and constructed in accordance with
these design and sizing criteria will be presumed to meet the minimum water quality performance
standards of the PCO and the Phase II laws. Failure to construct storm water treatment practices in
accordance with these criteria may subject the violator to a civil penalty as described in § 155.807
of the PCO.
2. RELATIONSHIP OF DESIGN MANUAL TO OTHER LAWS AND REGULATIONS. If the specifications or

other provision of law, whichever provision is more restrictive or imposes higher protective
standards for human or environmental health, safety, and welfare, shall control.
2. PRIVATE AGREEMENTS. The PCO is not intended to revoke or repeal any easement, covenant, or
other private agreement. However, where the regulations of the PCO are more restrictive or impose
higher standards or requirements than such easement, covenant, or other private agreement, then the
requirements of the PCO shall govern. Nothing in the PCO shall modify or repeal any private
covenant or deed restriction, but such covenant or restriction shall not legitimize any failure to
comply with the PCO. In no case shall the Town be obligated to enforce the provisions of any
easements, covenants, or agreements between private parties. [formerly known as § 154.008]

The Concept Plan should be submitted for review along with sketch plans for the project. The
purpose of the Concept Plan is to demonstrate how a proposed project shall comply with the post
construction ordinance requirements in the early stages of project design. At the time of submittal
of a Concept Plan the Storm Water Administrator or land owner or the land owner’s duly authorized
agent or anyone having interest in the property, by reason of a written contrac t with the owner, may
request consultation(s) on a Concept Plan for the post construction storm water management system
to be utilized in the proposed development project. This consultation meeting(s) should take place
at the time of the preliminary plan of the subdivision, submission of a rezoning application, or other
early step in the development process. The purpose of this meeting(s) is to discuss the post
construction storm water management measures necessary for the proposed project, as well as to
discuss and assess constraints, opportunities and potential approaches to storm water management
designs before formal site design engineering is commenced. Local watershed plans and other
relevant resource protection plans may be consulted in the discussion of the Concept Plan. To
accomplish this goal the following information should be included in the Concept Plan, which
should be submitted in advance of the meeting as specified in the Administrative Manual.
a. EXISTING CONDITIONS / PROPOSED SITE PLANS. A Concept Plan shall include existing
conditions and proposed site layout sketch plans, which illustrate at a minimum: existing
and proposed topography; perennial and intermittent streams; mapping of predominant
soils from soil surveys; boundaries of existing predominant vegetation and proposed limits
of clearing and grading; proposed Undisturbed Open Space area; and location of existing
and proposed roads, buildings, parking areas and other impervious surfaces.
b. NATURAL RESOURCES INVENTORY. A Concept Plan submitted prior to a consultation
meeting shall include a written or graphic inventory of the natural resources at the site and
surrounding area as it exists prior to the commencement of the project. This description
should include a discussion of soil conditions, forest cover, geologic features, topography,
wetlands, and native vegetative areas on the site, as well as the location and boundaries of
other natural feature protection and conservation areas such as lakes, ponds, flood plains,
stream buffers and other setbacks (e.g., drinking water well setbacks, septic system
setbacks, etc.) Particular attention should be paid to environmentally sensitive features that
provide particular opportunities or constraints for development.
c. STORM WATER MANAGEMENT SYSTEM CONCEPT PLAN. A Concept Plan shall include the
proposed post construction storm water management system including: preliminary
selecting and location of proposed structural storm water controls; low impact design
elements; location of existing and proposed conveyance systems such as grass channels,
swales, and storm drains; flow paths; location of proposed Undisturbed Open Space areas;
location of all floodplain/floodway limits; relationship of site to upstream and downstream
properties and drainages; and preliminary location of proposed stream channel
modifications, such as bridge or culvert crossings.
2. STORM WATER MANAGEMENT PERMIT APPLICATION. The storm water management permit
application shall detail how post construction storm water runoff will be controlled and managed
and how the proposed project will meet the requirements of the PCO, including § 155.803,
Standards. All such plans submitted with the application shall be prepared by a registered North
Carolina professional engineer or landscape architect. The engineer or landscape architect shall

Administrator. Incomplete submittals shall be treated pursuant to § 155.802.B.5.
3. AS-BUILT PLANS AND FINAL APPROVAL. The applicant shall certify that the completed project is in
accordance with the approved storm water management plans and designs, and shall submit actual
“as- built” plans for all storm water management facilities or practices after final construction is
completed. Failure to provide approved as-built plans within the time frame specified by the Storm
Water Administrator may result in assessment of penalties as specified in § 155.807, Violations and
Enforcement. At the discretion of the Storm Water Administrator, performance securities or bonds
may be required for storm water management facilities or practices until as -built plans are approved.
As-built plans shall show the final design specifications for all storm water management facilities
and practices and the field location, size, depth, and planted vegetation of all measures, controls,
and devices, as installed, and location and size of all Undisturbed Open Space areas and tree
plantings. The designer of the storm water management measures and plans shall certify, under seal,
that the as-built storm water measures, controls, and devices are in compliance with the approved
storm water management plans and designs and with the requirements of the PCO. Final as -built
plans and a final inspection and approval by the Storm Water Administrator are required before a
project is determined to be in compliance with the PCO. At the discretion of the Storm Water
Administrator, certificates of occupancy may be withheld pending receipt of as-built plans and the
completion of a final inspection and approval of a project.[formerly known as § 154.023]
D. APPROVALS.
1. EFFECT OF APPROVAL. Approval authorizes the applicant to go forward with only the specific plans
and activity authorized in the permit. The approval shall not be construed to exempt the applicant
from obtaining other applicable approvals from local, state, and federal authorities.
2. TIME LIMIT/EXPIRATION. A Storm Water Management Permit and accompanying plan approved
under the provisions of the PCO shall remain valid for a period of three (3) years from the date of

[formerly known as § 154.025]

155.803. Standards [formerly § 154, Section III]

A. GENERAL STANDARDS. All development and redevelopment to which the PCO applies shall comply with the
standards of this section. [formerly known as § 154.031]
1. All built-upon area for development and redevelopment subject to the requirements of this PCO
shall be at a minimum thirty feet (30’) landward of all perennial and intermittent surface waters.
This built-upon area setback can be located within the stream buffer area defined by this PCO, but
any disturbances within the built-upon area setback must also comply with SWIM buffers and
detention standards as outlined at § 155.704, and regulated floodways as outlined in Chapter 9 . A
surface water shall be deemed present if the feature is approximately shown on either the most recent
version of the soil survey map prepared by the Natural Resources Conservation Service of the United
States Department of Agriculture or the most recent version of the 1:24,000 scale (7.5 minute)
quadrangle topographic maps prepared by the United States Geologic Survey (USGS). An
exception to this requirement shall be granted if one or more of the following is satisfied and
documented:
a. Based on an on-site determination by the Storm Water Administrator or designee, surface
waters are not present on the site. When a landowner or other affected party believes that
the maps have inaccurately depicted surface waters, he or she shall consult the Storm Water
Administrator or designee. Upon request, the Storm Water Administrator or designee shall
make on-site determinations. Surface waters that appear on the maps shall not be subject
to this Chapter if this on-site determination shows that they fall into one of the following
categories:
i. Ditches and manmade conveyances other than modified natural streams unless
constructed for navigation or boat access;
ii. Manmade ponds and lakes located outside natural drainage ways;
iii. Ephemeral (storm water) streams.
b. Based on a variance issued pursuant to § 155.802.E., unnecessary hardships would result
from the strict application of this requirement.
c. Based on a determination by the Storm Water Administrator, a lack of practical alternatives
exists for accomplishing the basic purpose of the project in a manner that would avoid or
result in less adverse impact to surface waters considering the potential for a reduction in
size, configuration, or density and all alternative designs.
B. WATERSHED DISTRICTS. Standards for development and redevelopment vary depending on the watershed
district in which a project is located as described in the Town’s “Post Construction Ordinance Map,” which
is adopted simultaneously as described in § 155.801.E.4. The Town is divided into the following watershed
districts for purposes of the PCO.

Page 8 - 14
2. DETERMINATION OF ADEQUACY; PRESUMPTIONS AND ALTERNATIVES. Storm water treatment
practices that are designed, constructed, and maintained in accordance with the criteria and
specifications in the Design Manual will be presumed to meet the minimum water quality and
quantity performance standards of the PCO. Whenever an applicant proposes to utilize a practice or
practices not designed and constructed in accordance with the criteria and specifications in the
Design Manual, the applicant shall have the burden of demonstrating that the practice(s) will satisfy
the minimum water quality and quantity performance standards of the PCO before it can be
approved for use. The Storm Water Administrator may require the applicant to provide such
documentation, calculations, and examples as necessary for the Storm Water Administrator to
determine whether such an affirmative showing is made.
3. SUBMITTAL OF DIGITAL RECORDS. Upon submittal of as-built plans, the location of storm drainage
pipes, inlets and outlets as well as the location of all BMPs as well as Undisturbed Open Space must
be delivered to the Storm Water Administrator in the digital format specified in the Design Manual.
[formerly known as § 154.035]
F. TOTAL PHOSPHOROUS MITIGATION FOR THE YADKIN DISTRICT.
1. PURPOSE. The purpose of this mitigation is to reduce the cost of complying with the seventy percent
(70%) total phosphorus removal criteria for developments exceeding fifty percent (50%) built-upon
area while ensuring the reduction of pollution loads and achievement of the ordinance objectives.
2. GENERAL DESCRIPTION. For the Yadkin District, there are two (2) total phosphorus mitigation
options available to developments greater than or equal to sixty percent (60%) built-upon area,
including offsite mitigation and a buy-down option as described in this Chapter. For developments
with greater than or equal to fifty percent (50%) and less than sixty percent (60%) built-upon area,
off-site mitigation only is allowed provided it occurs in the same named creek system. Both off-site
and buy-down mitigation will result in the construction of retrofit BMPs. In addition, the buy-down
option is available provided the Town of Matthews has projects and/or property available for
mitigation. There is no total phosphorus requirement in the Catawba District so the mitigation option
is not necessary.
3. CRITERIA FOR OFF-SITE MITIGATION FOR THE YADKIN DISTRICT.
a. The owner or designee of a proposed construction site that will include greater than or
equal to fifty percent (50%) built upon area shall construct a BMP retrofit project designed
to achieve an equivalent or greater net mass removal of total phosphorus as would be
achieved by removing seventy percent (70%) of the total phosphorus from the proposed
site. Off-site mitigation is allowed only for total phosphorus removal above fifty percent
(50%). On-site BMPs shall be constructed to achieve fifty percent (50%) removal of total
phosphorus.
b. The Storm Water Administrator shall receive, review, approve, disapprove or approve with
conditions an “Application for Off-Site Total Phosphorus Mitigation.” The Storm Water
Administrator shall design this application to include all pertinent information. This
application shall be submitted with the storm water management permit application and
shall at a minimum contain a description of the BMP(s) to be constructed, including their
type and size as well as the pollutant removal efficiencies to be achieved. The location of
the site where the BMP(s) are to be constructed shall be described, including the size of
the drainage area to be treated and percentage and type of existing built upon area. The
application must also include the pounds of total phosphorus being mitigated for and the
pounds of total phosphorus reduced with the retrofit BMP(s). A legally valid instrument
shall be submitted with the application to demonstrate that the applicant has land rights to
perform the BMP retrofit on the property.
c. The criteria for approval of offsite total phosphorus mitigation by the Storm Water
Administrator are as follows:
i. BMP(s) must be constructed in accordance with 15A NCAC 2H .1008(c), as
explained in the Design Manual.
ii. BMP(s) must be sized for the corresponding watershed area according to the
Design Manual.

TOWN OF MATTHEWS UNIFIED DEVELOPMENT ORDINANCE

Page 8 - 15
iii. BMP(s) must be inspected by the Storm Water Administrator and found to be in
compliance with all approved plans and specifications prior to the release of
occupancy permits for the mitigated site.
iv. Following approval from the Storm Water Administrator, BMP(s) may be
installed and credits obtained for pounds of total phosphorus removed that can be
applied to future projects. These credits can be accumulated or “banked” for a
period of time as specified by the Storm Water Administrator in the
Administrative Manual.
v. All off-site mitigation BMPs shall be subject to the maintenance requirements as
well as installation and maintenance performance securities specified in §
155.806.
4. CRITERIA FOR TOTAL PHOSPHORUS BUY-DOWN OPTION FOR THE YADKIN DISTRICT.
a. The owner or designee of a proposed construction site that will include greater than or
equal to sixty percent (60%) built upon area may “buy-down” the seventy percent (70%)
phosphorus removal requirement to no less than fifty percent (50%). On-site BMPs must
be installed to remove the remaining total phosphorus load. The money shall be used by
the Town of Matthews to construct BMP retrofit projects designed to achieve an equivalent
or greater net mass removal of total phosphorus as would be achieved by removing seventy
percent (70%) of the total phosphorus from the proposed site.
b. The Storm Water Administrator shall receive, review, approve, disapprove or approve with
conditions an “Application for Total Phosphorus Buy-Down.” The Storm Water
Administrator shall design this application to include all pertinent information. This
application shall be submitted with the storm water management permit application and
shall at a minimum contain calculations showing the total load buy-down and all cost
calculations as described in the Design Manual.
c. The criteria for the buy-down option are as follows:
i. The buy-down option shall not be approved by the Storm Water Administrator
unless projects and/or properties are available for mitigation, including BMP
construction, BMP maintenance, BMP rehabilitation and stream restoration.
ii. There is no time constraint for the Town of Matthews to spend mitigation money;
however, the Town shall strive to spend buy-down monies in a timely and
efficient manner such that a net improvement in water quality results.
iii. All BMPs constructed by the Town of Matthews as part of this mitigation option
shall be maintained by the Town of Matthews into perpetuity.
d. The criteria for calculating the buy down cost shall be provided in the Design
Manual.[formerly known as § 154.036]
G. DEED RECORDATION AND INDICATIONS ON PLAT. The approval of the storm water management permit shall
require an enforceable restriction on property usage that runs with the land, such as plat, recorded deed
restrictions or protective covenants, to ensure that future development and redevelopment maintains the site
consistent with the approved project plans. The location of all designated Undisturbed Open Space for a site
shall be recorded at the Register of Deeds Office as “Undisturbed Open Space.” Streams and buffer
boundaries including the delineation of each buffer zone must be specified on all surveys and record plats.
The applicable operations and maintenance agreement pertaining to every structural BMP shall be referenced
on the final plat and shall be recorded with the Mecklenburg County Register of Deeds Office upon final plat
approval. If no subdivision plat is recorded for the site, then the operations and maintenance agreement shall
be recorded with the Mecklenburg County Register of Deeds Office so as to appear in the chain of title of all
subsequent purchasers under generally accepted searching principles. A copy of the recorded maintenance
agreement shall be provided to the Storm Water Administrator within fourteen (14) days following receipt
of the recorded document. A maintenance easement shall be recorded for every structural BMP to allow
sufficient access for adequate maintenance. The specific recordation and deed restriction requirements as
well as notes to be displayed on final plats and deeds shall be contained in the Administrative Manual.

155.804. Development and Redevelopment Mitigation [formerly § 154, Section IV]

A. MITIGATION PAYMENT. Development and redevelopment on a lot less than one (1) acre in size measured in
accordance with § 155.801.F.8 that is not exempt according to § 155.801.E.2 is allowed by right to forego
meeting the requirements of the PCO provided the Town is paid a mitigation fee according to rates set forth
in the Administrative Manual and provided such development and redevelopment are not part of a larger
common plan of development or sale, even though multiple, separate or distinct activities take place at
different times on different schedules. [formerly known as § 154.041]
B. CRITERIA FOR MITIGATION PAYMENT.
1. NOTIFICATION TO STORM WATER ADMINISTRATOR. The by-right mitigation option does not require
approval by the Storm Water Administrator; however, notification that this right is to be exercised
for a particular lot must be made prior to the issuance of any permits for the project. This notification
is to be made to the Storm Water Administrator on a standard form provided in the Administrative
Manual.
2. USE OF MITIGATION PAYMENT. The Town shall use the mitigation payment to install water quality
enhancement measures, including but not limited to BMPs, stream restoration, open space
preservation, etc. BMP(s) installed using the mitigation payment must be constructed in accordance
with 15A NCAC 2H .1008(c), as explained in the Administrative Manual. All BMPs constructed by
the Town as part of this mitigation option shall be maintained by the Town of Matthews into
perpetuity.
3. TIME FRAME FOR USE OF MITIGATION PAYMENT. The Town shall use the mitigation payment within
a maximum of two (2) years of the end of the calendar year from the receipt of the payment. As an
option, the Town of Matthews may elect to use the fee to purchase and plant trees within the Town.
[formerly known as § 154.042]

155.805. Undisturbed Open Space [formerly § 154, Section V]

A. PURPOSE. Undisturbed Open Space provides for a reduction in the negative impacts from storm water runoff
through nonstructural means. The combination of the structural BMPs described in § 155.803 with the non-
structural Undisturbed Open Space provisions described in this § 155.805 allow the objectives of the PCO to
be fulfilled. [formerly known as § 154.051]
B. GENERAL DESCRIPTION. Undisturbed Open Space is required for all development unless mitigated. The
percentage of Open Space required depends on a project’s built-upon area as described below. Undisturbed
Open Space requirements can be met in stream or lake buffers, designated common areas or on individual
lots for residential development (e.g., backyards, borders, etc.). Undisturbed Open Space cannot be
designated within rights of way, utility easements, etc. where re-disturbance could occur. Grass fields can
also be used to meet Undisturbed Open Space requirements; however, the fields must be replanted in
accordance with the tree planting provisions described in § 155.805.E. below. Undisturbed Open Space is
preferred where it will provide maximum water quality benefit (i.e., around gullies and existing drainage
areas, adjacent to streams and wetlands, around structural BMPs, etc.). [formerly known as § 154.052]
C. UNDISTURBED OPEN SPACE CRITERIA. Undisturbed Open Space requirements apply to projects as described
below.
1. LESS THAN TWENTY FOUR PERCENT (24%) BUILT-UPON AREA. A project with less than twenty four
percent (24%) built-upon area shall include as Undisturbed Open Space within the boundaries of
the project a minimum of twenty five percent (25%) of the project area.
2. GREATER THAN OR EQUAL TO TWENTY FOUR PERCENT (24%) AND LESS THAN FIFTY PERCENT (50%)
BUILT-UPON AREA. A project with greater than or equal to twenty four percent (24%) and less than
fifty percent (50%) built-upon area shall include as Undisturbed Open Space within the boundaries
of the project a minimum of seventeen and one-half percent (17.5%) of the project area.

TOWN OF MATTHEWS UNIFIED DEVELOPMENT ORDINANCE

Page 8 - 17
3. GREATER THAN OR EQUAL TO FIFTY PERCENT (50%) BUILT-UPON AREA. A project with greater than
or equal to fifty percent (50%) built upon area shall include as Open Space within the boundaries of
the project a minimum of ten percent (10%) of the project area. [formerly known as § 154.053]
D. UNDISTURBED OPEN SPACE DESIGNATION. The Undisturbed Open Space location shall be recorded at the
Register of Deeds Office as “Undisturbed Open Space” and future disturbance is prohibited except for
greenway trails with unlimited public access, Charlotte - Mecklenburg Utility lines and channel
work/maintenance activities by Charlotte-Mecklenburg Storm Water Services. Other utility work may be
allowed in the Undisturbed Open Space area provided it will not result in loss of Undisturbed Open Space as
approved by the Town of Matthews. [formerly known as § 154.054]
E. UNDISTURBED OPEN SPACE MITIGATION.
1. PURPOSE. The purpose of this mitigation is to reduce the cost of complying with the Undisturbed
Open Space requirement while ensuring the reduction of pollution loads and achievement of the
ordinance objectives.
2. GENERAL DESCRIPTION. Approved disturbance to the Open Space area described in § 155.805.C.
above must be off-set by an allowable form of mitigation, including on-site and off-site mitigation
as well as through payment-in-lieu.
3. UNDISTURBED OPEN SPACE MITIGATION CRITERIA.
a. ON-SITE MITIGATION. On-site mitigation shall allow the disturbance of designated
Undisturbed Open Space area on a project with the fulfillment of the following criteria on
the project site:
i. Fifty percent (50%) increase in total Undisturbed Open Space area designation
above the requirements specified in § 155.805.D, except when the Undisturbed
Open Space area qualifies as a “grass field” in which case the size of the required
Undisturbed Open Space area remains unchanged. The portion of the Open Space
area that is a grass field, whether or not disturbed, must be replanted with trees as
specified in subsection 3, below.
ii. Establishment of a minimum of six inches (6”) of top soil to the disturbed Open
Space area following the completion of construction activities. This material may
be obtained from on-site when available.
iii. Planting of a minimum of thirty six (36) trees per acre of Undisturbed Open Space
area as follows:
 Trees shall have a minimum caliper of one and one-half inches (1.5”).
 Trees shall be of a quality set forth by the American Standard for Nursery
Stock and will be selected from a list of acceptable native species for
planting in Undisturbed Open Spaces established by the Town of
Matthews.

site mitigation through the acceptance for ownership or conservation easement properties
for the protection of Undisturbed Open Space, provided the result will be an increased
protection of water quality over what would be attained through preservation of
Undisturbed Open Space or on site mitigation (see Administrative Manual).
c. PAYMENT - IN - LIEU OF UNDISTURBED OPEN SPACE DEDICATION. Payment-in-lieu of
Undisturbed Open Space dedication is only allowed for industrial and commercial
developments and multi-family projects that are in excess of fifty percent (50%) built upon
area. Payment-in-lieu shall only be allowed to the extent an approved disturbance cannot
be offset by onsite mitigation as determined by the Storm Water Administrator. The
following criteria shall be fulfilled for the payment-in-lieu option:
i. A fee shall be paid to the Town or its designee based on the following formula:
1.25 x (appraised value of subject property including intended use without
improvements). The appraised value of the subject property shall be determined
by a licensed, independent real estate appraiser retained by the developer or
owner. The Town may accept the appraised value or at its discretion obtain its
own appraisal. In the event the parties cannot agree on the appraised value, the
two appraised values shall be averaged together to determine the final appraised
value to be used in the formula above.
ii. Payment shall be accepted by the Town or its designee prior to land disturbing
activities.
iii. The Town shall use the payment-in-lieu to purchase Undisturbed Open Space in
the same river basin (Yadkin or Catawba) as the property to be disturbed within a
maximum of two (2) years of the end of the calendar year from the receipt of the
payment. As an option, the Town may elect to use up to ten percent (10%) of the
fee to purchase and plant trees within the Town.
4. APPROVAL CRITERIA FOR UNDISTURBED OPEN SPACE MITIGATION.
a. APPLICATION FOR UNDISTURBED OPEN SPACE MITIGATION. The Storm Water
Administrator shall receive, review, approve, disapprove or approve with conditions an
“Application for Undisturbed Open Space Mitigation.” The Storm Water Administrator
shall design this application to include all pertinent information, including at a minimum a

and an effective demonstration that all reasonable efforts have been undertaken to fulfill
the Undisturbed Open Space requirement on the particular site. An application for on-site
mitigation shall show the location of the restored Undisturbed Open Space on the property
and the location, type and size of all trees and ground cover to be planted as well as contain
a warranty statement for the trees. An off-site mitigation application shall show the location
and description including acreage, etc. of the property to be used for mitigation and contain
a legally valid instrument demonstrating that the applicant has legal title to the property for
transfer to the Town. A payment-in-lieu application shall at a minimum contain the location
and description of the site to be mitigated and an approved appraisal by a licensed,
independent real estate appraiser
b. PRE-APPROVED UNDISTURBED OPEN SPACE MITIGATION. The following is pre-approved
for on-site mitigation and does not require the submittal of an application to the Storm
Water Administrator; however, these mitigation areas shall be described on the storm water
management permit application.
i. Residential, Commercial and Multifamily Uses: twenty five percent (25%) of the
required Undisturbed Open Space area as described in § 155.805.D is preapproved
for on-site mitigation provided the size of mitigation area is one hundred fifty

B. OPERATION AND MAINTENANCE AGREEMENT.
1. GENERAL. At the time that as-built plans are provided to the Storm Water Administrator as described
in § 155.802.C.3 and prior to final approval of a project for compliance with the PCO, but in all
cases prior to placing the BMPs in service, the applicant or owner of the site must execute an
operation and maintenance agreement that shall be binding on all current and subsequent owners of
the site, portions of the site, and lots or parcels served by the structural BMP. This maintenance
agreement shall be recorded as specified in § 155.803.G. Failure to execute an operation and
maintenance agreement within the time frame specified by the Storm Water Administrator may
result in assessment of penalties as specified in § 155.807, Violations and Enforcement. Until the
transference of all property, sites, or lots served by the structural BMP, the original owner or
applicant shall have primary responsibility for carrying out the provisions of the maintenance
agreement. At the discretion of the Storm Water Administrator, certificates of occupancy may be
withheld pending receipt of an operation and maintenance agreement. The operation and
maintenance agreement shall require the owner or owners to maintain, repair and, if necessary,
reconstruct the structural BMP, and shall state the terms, conditions, and schedule of maintenance
for the structural BMP. In addition, it shall grant to the Town a right of entry in the event that the
Storm Water Administrator has reason to believe it has become necessary to inspect, monitor,
maintain, repair, or reconstruct the structural BMP; however, in no case shall the right of entry, of
itself, confer an obligation on the Town to assume responsibility for the structural BMP. Standard
operation and maintenance agreements for BMPs shall be developed by the Storm Water
Administrator and made available in the Design Manual. The operation and maintenance agreement
must be approved by the Storm Water Administrator prior to plan approval, and it shall be referenced
on the final plat as described in § 155.803.G.
2. SPECIAL REQUIREMENT FOR HOMEOWNERS AND OTHER ASSOCIATIONS. For all structural BMPs
required pursuant to the PCO not covered under § 155.806.A.1 and that are to be or are owned and
maintained by a homeowners’ association, property owners’ association, or similar entity, the

not request a hearing as provided in § 155.807.C.2.e, the Storm Water Administrator shall
request the initiation of a civil action to recover the amount of the assessment. The civil
action shall be brought in Mecklenburg County Superior Court or in any other court of
competent jurisdiction. A civil action must be filed within three (3) years of the date the
assessment was due. An assessment that is appealed is due at the conclusion of the
administrative and judicial review of the assessment.
e. APPEAL OF REMEDY OR PENALTY. The issuance of an order of restoration and/or notice of
assessment of a civil penalty by the Storm Water Administrator shall entitle the responsible
party or entity to an appeal before the Storm Water Advisory Committee (SWAC) if such
Person submits written demand for an appeal hearing to the Clerk of SWAC within thirty
(30) days of the receipt of an order of restoration and/or notice of assessment of a civil
