CREATION, EXTENSION, MODIFICATION, OR CONNECTION TO THE STORMWATER UTILITY SYSTEM (THE MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) 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; Concord, North Carolina, Code of Ordinances (Supp. No. 50, Update 4) Created: 2021-10-04 10:07:33 [EST] Page 1 of 10 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. (Supp. No. 50, Update 4) Created: 2021-10-04 10:07:32 [EST] Page 2 of 10 (Ord. No. 07-108, § 1, 12-13-2007) 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. (Ord. No. 07-108, § 1, 12-13-2007) 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. (Ord. No. 07-108, § 1, 12-13-2007) (Supp. No. 50, Update 4) Created: 2021-10-04 10:07:32 [EST] Page 3 of 10 Sec. 60-80. Pre -construction conference and issuance of permit.
