ARTICLE V. CREATION, EXTENSION, MODIFICATION, OR CONNECTION TO THE
STORMWATER UTILITY SYSTEM (THE MUNICIPAL SEPARATE STORM SEWER
SYSTEM (MS4)
Sec. 60-76. Purpose of article.
The purpose of this article is to set forth the standards by which the city's municipal separate storm sewer
system (MS4) may be extended.
The standards of this article apply to all extensions, both publicly and privately owned. In addition, this article
contains standards for private extensions planned to be incorporated into the MS4.
The city provides the MS4 in public rights -of -way and city stormwater easements according to the provisions
of this chapter. In an effort to plan for future extensions of the Concord stormwater management system, the city
maintains a Capital Improvement Plan (C.I.P.). The city shall endeavor to provide the extensions and services
proposed in the C.I.P. if funded through the city's capital improvements budget. Extensions to the system may be
made during the course of development. Consideration shall be given to each proposed developments in
conformity to the city's "stormwater master plan," the adopted land use and other plans of the city, and the city's
adopted annexation plan. If an extension or stormwater control measure is authorized, then all city design
standards shall be met and the permit application process in [Unified Development Ordinance] (UDO) Articles 4
and 5 or 6 shall be followed. All such extensions shall become a part of the city's MS4 if accepted for public
ownership and maintenance by the city council.
(Ord. No. 07-108, § 1, 12-13-2007)
Sec. 60-77. Procedures and standards for creation, extension, modification, or connection to
the Concord Municipal Separate Storm Sewer System (MS4).
(a) Prior to application submittal. Preliminary site plans and engineering plans shall be prepared in accordance
with the city's ordinances, including this chapter 60, the UDO (see article 4 and articles 5 or 6), and the city's
technical standards manual prior to an application package submittal. Applicants shall meet with the city's
stormwater administrator or his designee to review these preliminary plans prior to the preparation of the
final plans and the application package.
(b) Application requirements.
(1) All persons intending to construct, alter, modify, expand or connect to any portion of the Concord
Stormwater Management System shall make timely and proper application to the city's stormwater
administrator and provide such information as may be required by the stormwater administrator and
director of engineering. At a minimum, the applicant shall:
Provide a plan that shows the acreage of the area to be served, identifies the type of
development (residential, commercial etc.), estimates the maximum potential demands that the
development may impose on the existing system, and determine the adequacy of the existing
system to meet those demands;

b. Provide a proposed schedule for the construction of the development and any proposed
development phases;
C. Document the intended use of the stormwater conveyance and control system extension;
d. Design and install the infrastructure in accordance with the C.I.P. and/or the city's standard
specifications and design standards. If the proposed extension has not been identified in a C.I.P.,
the design engineer shall evaluate the infrastructure's ability to adequately serve surrounding
sites in the area of consideration. This evaluation shall be reviewed and approved by the
stormwater administrator or his designee;
e. Contract and fund the complete range of design services required for all on -site and off -site
utilities. The alignment and design of the utilities shall meet the intent of a project identified in
the city's standard specifications and design standards. The design shall meet the design
standards of this article and shall be submitted to the city for review and approval in accordance
with this chapter. Designs and alignments that do not comply with the intent of the C.I.P. and/or
the city's standard specifications and design standards may be rejected regardless of project's
compliance with other portions of this chapter.
f. Grant to the city, at no cost, all on -site utility rights -of -way and easements deemed necessary by
the stormwater administrator and the director of engineering.
(c) Incomplete application package. Any application package determined incomplete by the stormwater
administrator shall be returned to the applicant. Revised engineering plans and specifications shall constitute
a re -submittal, shall be accompanied by a new fee, and shall require additional time for review. A complete
application package that contains sufficient information to ascertain reasonable grounds to believe the
application package and its contents meet all applicable standards of this chapter shall be acknowledged by a
letter setting a date for a pre -construction conference. No discussion at the review conference shall preclude
or otherwise bar the city from denying a permit, or issuing a permit that incorporates conditions, based upon
changed circumstances or information not previously known by the stormwater administrator or the
applicant. In either event, no single submittal of an application package will be held open for review longer
than 90 days without the issuance of a letter requesting additional information or an "authorization to
construct" permit being issued following a pre -construction conference. Application packages delayed by
lack of action by any person or entity other than the city shall be deemed denied and shall require re -
submittal.
(d) Authorization to construct. It shall be unlawful to begin the construction of a building or project
infrastructure until the stormwater administrator has issued an "authorization to construct" permit, and any
additional required permits have been issued by either the city, Cabarrus County and/or the State of North
Carolina, as needed and required.
(e) Funding of oversized utilities. The city shall take reasonable steps to ensure that adequate funding is
available to accommodate any requested oversizing or upsizing needs, as provided in section 60-78 below,
however the city cannot guarantee the funding of specific proposed projects.
(f) Standards for Concord separate stormwater sewer system (MS4) extensions and/or connections. The
responsibility for and cost of such extension within new developments shall be borne by the requesting
party, unless upsizing is required by the city in accordance with section 60-78. Where a proposed
development of property located within the city necessitates a replacement, upgrade, or expansion in size or
capacity of stormwater conveyance and appurtenant facilities that are already available to serve the
property (as opposed to an extension of a line to make service available), and the replacement, upgrade, or
expansion for the proposed development cannot be constructed in the time requested by the owner or
developer under the city's scheduled and budgeted C.I.P. or capital improvements budget, the city may enter
into a contract with the owner or developer of such property pursuant to which the owner or developer shall
pay some or all of the cost of the necessary improvements.

Sec. 60-78. Standards for oversizing Concord's Stormwater Management System and
infrastructure reimbursement agreements.
(a) Pursuant to G.S. 160A-499 this section authorizes and sets forth the procedures and terms under which the
city may approve reimbursement agreements with private developers and property owners for the design
and construction of MS4 that is included on the city's capital improvement plan and serves the developer or
property owner.
(b) The city manager, or designee, is authorized to negotiate municipal infrastructure reimbursement
agreements with private developers and property owners pursuant to this section. In negotiating such
agreements, the city manager, or designee, shall determine that:
(1) The cost to the city will not exceed the estimated cost of providing for the municipal infrastructure
through either eligible force account qualified labor or through a public contract let pursuant to G.S.
143-128 et seq.; or
(2) The coordination of separately constructed municipal infrastructure with the associated private
development would be impracticable.
(3) City approval authority for agreements under this section shall be governed by general city contracting
authorizations and delegations.
(c) Such reimbursements, if any, may be paid from any lawful source if approved by the city council.
(d) A municipal infrastructure reimbursement agreement approved pursuant to this section shall not be subject
to G.S. Ch. 143, Art. 8 unless the award of a contract for work would have required competitive bidding if the
contract had been awarded by the city. If the city would have been required to follow G.S. Ch. 143, Art. 8,
then the developer or property owner is required to comply with the requirements of G.S. Ch. 143, Art. 8.
(e) A municipal infrastructure reimbursement agreement approved pursuant to this section shall require the
private developer or property owner party to comply with all of the city's rules, regulations and ordinances
and be current on all debts, fees or taxes owed to the city.

Sec. 60-79. Infrastructure capital recovery fee for CIP investments.
The Concord Stormwater Management Program will exercise a capital investment program following the
needs identified in the stormwater master plan and to meet other infrastructure and water quality needs as they
are identified by other means, based upon the availability of funds and approval by city council. As pipe sizes are
upsized and regional stormwater detention and/or treatment systems are installed to accommodate future land
development, a significant capital investment is made by the city that includes annual maintenance and
monitoring costs. When new developments are constructed that will have access to these city owned and
operated facilities, the new developments will be required to pay a proportionate share of the capital investment
and operating costs associated with all downstream pipes and detention and/or treatment facilities. The cost of
these capital recovery fees will be charged to the developer and must be paid prior to receiving final plat approval.
