III.STORMWATER BEST MANAGEMENT PRACTICES (BMPs) MANUAL The Watershed Administrator (Town of Kernersville staff, located at the Community Development Department-Engineering Division, in charge of the issue of the Town Watershed/Stormwater Permit) and Stormwater Administrator (Town of Kernersville staff, located at the Public Services Department- Stormwater Division, in charge of the Town of Watershed and Stormwater Administrative Manual 1 Revised 2020-02-01 Kernersville BMP(s) Inspection Program) shall use the policies, criteria, and information, including technical specifications and standards, in the most current revision of the North Carolina Stormwater Best Management Practice Manual; and for publicly funded linear transportation projects, the North Carolina Department of Transportation Stormwater Best Management Practices Toolbox; as the basis for decisions about Watershed/Stormwater permits and about the design, implementation and performance and maintenance of structural and non-structural stormwater BMPs. The North Carolina Stormwater Best Management Practices Manual includes a list of acceptable stormwater treatment practices, BMP(s), including the specific design criteria for each stormwater practice. Stormwater treatment practices that are designed, constructed, and maintained in accordance with these design and sizing criteria will be presumed to meet the minimum water quality performance standards of the Town of Kernersville Stormwater and Watershed regulations. The Town of Kernersville Design and Construction Specifications document is also a useful reference for designers and developers. This manual was approved by the Board of Alderman as a Town ordinance and contains information pertinent to other stormwater infrastructure designs. If the standards, specifications, guidelines, policies, criteria, or other information in the North Carolina Stormwater Best management Practices Manual and in North Carolina Department of Transportation Stormwater Best Management Practices Toolbox are amended subsequent to the submittal of an application for approval pursuant to the Town of Kernersville Stormwater/Watershed regulations but prior to approval, the new information shall control and shall be utilized in reviewing the application and in implementing the Town of Kernersville Stormwater/Watershed regulations with regard to the application. The most current version of the North Carolina Stormwater Best management Practices Manual and the North Carolina Department of Transportation Stormwater Best Management Practices Toolbox shall apply regarding the date of submittal of a new application. A digital copy of The North Carolina Stormwater Best Management Practices Manual is available at the North Carolina Department of Environment and Natural Resources (NCDENR) website; Division of Energy, Mineral and Land Resources; Land Quality Section under the following link: NCDENR - Stormwater BMP Manual A digital copy of The North Carolina Department of Transportation Stormwater Best Management Practices Toolbox is available at the North Carolina Department of Transportation website; Programs; Environmental Programs; Environmental Excellence; Environmental Hot Topics; Stormwater Program; NPDES Permit under the following link: https://connect.ncdot.gov/resources/hydro/Storm water%20Resources/Stormwater%20Best%20M anagement%20Practices%20Toolbox%20- %20March%202008.pdf A digital copy of The Town of Kernersville Design and Construction Specifications document is available at the Town of Kernersville Website under the following link: Town of Kernersville – Business Information - Permits, Ordinances, & http://toknc.com/documents/files/SpecBook.pdf IV. WATERSHED / STORMWATER PERMIT PROCESS A. Purpose and Application The purpose of the Watershed and Stormwater Permit Process is to provide a mechanism for the review, approval, and inspection of the approach to be used for the management and control of Stormwater for a development or redevelopment site consistent with the requirements of the Town of Kernersville’s UDO, whether the approach consists of structural BMPs or other techniques such as low-impact or low-density design. Compliance after project construction is Watershed and Stormwater Administrative Manual 2 Revised 2020-02-01 assured by the maintenance provisions of the Town of Kernersville Stormwater and Watershed Ordinances. A Watershed/Stormwater Permit is required for all development and redevelopment unless exempt pursuant to the Town of Kernersville Stormwater and Watershed Ordinances. No building or built-upon area shall be erected or expanded, nor shall any building or zoning permit be issued until a Watershed/Stormwater Permit has been issued by the Watershed Administrator or Town Manager’s designee. A properly submitted packet (plans, calculation, legal documents, etc.), as well as a reviewed and approved Watershed/Stormwater Permit Application, are required for the issuance of a Watershed/Stormwater Permit. All plans submitted with the application shall be prepared by a registered North Carolina professional engineer or landscape architect. The engineer or landscape architect shall perform services only in their area of competence and shall verify that the design of all stormwater management facilities and practices meets the submittal requirements for complete applications; that the designs and plans are sufficient to comply with applicable standards and policies found in the North Carolina Stormwater Best Management Practices Manual, and the North Carolina Department of Transportation Stormwater Best Management Practices Toolbox if it is a linear transportation project; and that the designs and plans ensure compliance with the Town of Kernersville Stormwater and Watershed Ordinances. B. Watershed/Stormwater Permitting Process The Watershed/Stormwater Permitting Process can be separated into three phases of stages: Planning, Preliminary Design, and Concept Plan; Final Stormwater Management Plan, Construction Drawing Review and Permitting; and Construction and Construction Inspections of Stormwater Control Structures-BMP(s). 1. Planning, Preliminary Design, and Concept Plan Before plans will be reviewed and approved for construction, preliminary site plans must be reviewed by the Watershed Administrator through the Community Development department review process. Based upon the review of existing conditions and site analysis, the designer should develop a concept site layout plan for the project. During the concept plan stage the site designer will perform most of the layout of the site including the preliminary stormwater management system design and layout. The stormwater concept plan allows the design engineer to propose a potential site layout and gives the developer and local review staff preliminary information regarding the stormwater management system for the proposed development. The following steps should be followed in developing the stormwater concept plan: a.Use appropriate site design approaches (see the North Carolina Stormwater Best Management Practices Manual) as applicable to develop the site layout, including: Preserving the natural feature conservation areas defined in the site analysis. Fitting the development to the terrain and minimizing land disturbance. Reducing impervious surface area through various techniques. Preserving and utilizing the natural drainage system wherever possible. b. Calculate preliminary estimates of the stormwater sizing criteria requirements for water quality, channel protection, overbank flooding protection and extreme flood protection based on the concept plan site layout. c.Perform screening and preliminary selection of appropriate structural Watershed and Stormwater Administrative Manual 3 Revised 2020-02-01 stormwater controls and identification of potential sitting locations. It is extremely important at this stage that stormwater design is integrated into the overall site design concept in order to best reduce the impacts of the development as well as provide for the most cost-effective and environmentally sensitive approach. The goal of maintaining natural hydrologic conditions as a site is developed, to the extent possible, can reduce the economic costs of stormwater management and minimize the negative environmental impacts associated with development. It is recommended that prior to the preparation of the Final Stormwater Plan; the owner or developer shall request a consultation meeting with the Watershed Administrator on a concept plan for the post-construction stormwater management system to be utilized in the proposed development project. This consultation meeting shall take place at the time of the preliminary plan of subdivision or other early step in the development process. The purpose of this meeting is to discuss the post- construction stormwater management measures necessary for the proposed project, as well as to discuss and assess constraints, opportunities and potential approaches to stormwater management designs before formal site design engineering is commenced. The development process will typically proceed much faster and smoother if the concept meeting is conducted very early in the process. Appendix 01 “Stormwater Concept Plan - Preliminary Site Plan Requirements Submittal Checklist” contains the list of the items that should be submitted to the Watershed Administrator for review purposes prior to the preparation and submittal of the Final Stormwater Management Plan and Construction Plans. The Stormwater Management System Concept Plan is only a portion of the preliminary submittal through the Community Development Department review process. The Community Development Department must approve the proposed preliminary site plan with respect to City ordinances and policies relating to all components of the development plan (e.g., zoning, subdivision, utility, landscape, etc.) in addition to the Stormwater Management System Concept Plan before the developer may submit an application and construction plans for the Watershed/Stormwater Permit. The “Planning, Preliminary Design, and Concept Plan” phase is outlined in Appendix 02 “Stormwater Management System Concept Plan Review Submittal Process” 2. Final Stormwater Management Plan, Construction Drawing Review, and Permitting The final Stormwater Management Plan ensures that requirements and criteria are being complied with and that opportunities are being taken to minimize adverse impacts from the development. The Final Stormwater Management Plan should consist of plans; narrative and supporting design calculations (hydrologic and hydraulic); proper documentation and adequate financial assurance for the proposed stormwater management system. For review purposes, the final stormwater management plan should include the following elements: a. Existing Conditions Hydrologic Analysis: Provide an existing condition hydrologic analysis for stormwater runoff rates, volumes, and velocities, which includes: Watershed and Stormwater Administrative Manual 4 Revised 2020-02-01 A topographic map of existing site conditions (minimum 2-foot contour interval recommended) with the basin boundaries indicated. Acreage, soil types and land cover of areas for each sub basin affected by the project. All perennial and intermittent streams and other surface water features. All existing stormwater conveyances and structural control facilities. Delineation of on-site and off-site drainage areas including number of acres. Direction of flow and exits from the site. Analysis of runoff from off-site areas upstream of the project site. Methodologies, assumptions, site parameters and supporting design calculations used in analyzing the existing conditions site hydrology. b.Post-Development Hydrologic Analysis: Provide a post-development hydrologic analysis for stormwater runoff rates, volumes, and velocities, which includes: A topographic map of developed site conditions (minimum 2-foot contour interval recommended) with the post-development basin boundaries indicated. Location of proposed roads, building, parking lots, etc. Total area of post-development impervious surfaces and other land cover areas for each sub basin affected by the project. Unified stormwater sizing criteria runoff calculations for water quality, channel protection, overbank flooding protection and extreme flood protection for each sub-basin. Location and boundaries of proposed natural feature protection and conservation areas. Methodologies, assumptions, site parameters and supporting design calculations used in analyzing the existing and proposed conditions site hydrology. c.Stormwater Management System: Provide drawings, design calculations and specifications for the proposed stormwater management system, including: A drawing of the stormwater management system including the location of nonstructural site design features and the placement of existing and proposed structural stormwater controls. This drawing should show design water surface elevations, storage volumes available from zero to maximum head, location of inlets and outlets, location of bypass and discharge systems, and all orifice/restrictor sizes. Narrative describing selection process for appropriate and effective structural stormwater controls. Plan view, Cross-sections and profile drawings and design details for each of the structural stormwater controls (BMPs) in the system. This should include supporting calculations to show that the structure is designed according to the applicable design criteria and the North Carolina Best Management Practices Manual. Hydrologic and hydraulic analysis of the stormwater management system for all applicable design storms (should include stage-storage or outlet rating curves, and inflow and outflow hydrographs). Drawings, design calculations and elevations for all existing and proposed stormwater conveyance elements including stormwater drains, pipes, culverts, catch basins, channels, swales and areas designed for overland flow. Watershed and Stormwater Administrative Manual 5 Revised 2020-02-01 d.Erosion and Sedimentation Control Plan: All projects which disturb more than one acre within the Town of Kernersville and its Extraterritorial Jurisdictional (ETJ) must have an approved Erosion and Sedimentation Control Permit from NC DENR. The developer shall submit one copy of the approved Erosion and Sedimentation Control Plans to the Watershed Administrator. e.Proper Documentation and adequate Financial Assurance for the Proposed Stormwater management system In addition to an approval for design construction plans for the proposed Stormwater Management System, and prior to obtaining a Watershed and Stormwater permit, the developer and/or property owner shall comply with others Watershed Protection and Storm water Runoff Ordinances requirements, which require as part of the permitting process the submittal of the following documents for review and approval by the Watershed Administrator and/or Watershed Review Committee: Complete Watershed and Stormwater Permit Application and payment of Stormwater Site Plan Review fees. The Watershed and Stormwater Permit Application fee must be paid with the submittal of the Permit Application in order for the application to be considered complete for review. The Town of Kernersville Schedule of Fees and Charges is in the approved current fiscal year Budget document available online at: Town of Kernersville - Finance Draft of an Operation and Maintenance Plan for each BMP (if applicable). Such plan shall specify all operation and maintenance work necessary for the stormwater control structure(s) and methods to be used to maintain or restore a stormwater control structure to design specifications in the event of failure. Include in this plan an annual budget for the maintenance and control of the wet detention basin. The approved Operation and Maintenance plan should be signed and notarized and submitted to the Town of Kernersville Engineering Division. Draft of the Operation and Maintenance Agreement for the BMPs (if applicable) meeting both Watershed Protection and Storm water Runoff Ordinances. The purpose of this agreement is to ensure that each BMP receives adequate maintenance so that it can satisfactorily perform its pollutant removal function, and meet the Town of Kernersville Watershed and Stormwater runoff regulations. The agreement also designates the responsible party who shall be in charge of maintaining the BMP. It serves as a legal document to ensure maintenance and also outlines the routine maintenance schedule for each BMP. The approved Operation and Maintenance Agreement shall be recorded in the office of the Register of Deeds and submitted to the Town of Kernersville Engineering Division. Deed of Easement. For a development that involves any stormwater control structure, the applicant shall convey unto the Town of Kernersville or its successors or assigns an easement and right-of-way establishing the right to ingress, egress, and regress over the property for the purpose of inspection, repair, or maintenance of the stormwater control structure(s). A description of the area containing the storm water control structure(s) within a drainage easement shall be contained within the deed filed with the Register of Deed together with any dedication necessary for access Watershed and Stormwater Administrative Manual 6 Revised 2020-02-01 to and from the stormwater control structure(s) and a public street. The approved deed of easement shall be recorded in the office of the Register of Deeds and submitted to the Town of Kernersville Engineering Division. Submit a Construction Performance Surety to the Town of Kernersville for the amount equal to one hundred percent twenty (120%) of the total cost of the storm water control structure (If applicable). Performance Sureties may be in the form of Standby Letters of Credit, Performance Bonds, and Cash. Please submit unit cost information pertaining to all storm water control structures and /or bids from the contractor hired to perform the work and any change orders related thereto as a method to determine the basis for cost of the work for the construction of the BMP. The Engineering Division will review and approve the total cost estimation for the construction of the BMP. Covenants and Restrictions (If applicable). For those developments having a permanent stormwater control structure, (Homeowner’s / Property Owner’s) Association Covenants, Conditions and Restrictions and Articles of Incorporation shall be reviewed and approved by the Watershed Review Committee prior to recordation of a plat. Maintenance Escrow Agreement (If applicable). For all structural BMPs that are to be or are owned and maintained by an owners’ association, the Town of Kernersville Stormwater Runoff Ordinance requires the establishment of an escrow account for the long term maintenance of the BMP(s); which can be spent solely for sediment removal, structural, biological or vegetative replacement, major repair, or reconstruction of the structural BMPs. Town of Kernersville No Practical Alternatives - Riparian Buffer Authorization Application Form (If applicable). Persons who wish to undertake uses designated as allowable or allowable with mitigation (as per the Table of Uses of the Jordan and Randleman Buffer Rules) shall submit a request for a “No practical alternatives” determination to the Town of Kernersville. A Buffer Authorization may be issued by the Town of Kernersville.

Appendices 06 to 11 contain templates of most of the documents mentioned above for the convenience and use of developers and property owners. Electronic copy of this model documents can be found at the Town of Kernersville Web-site under the following link: Town of Kernersville - Applications and Forms Additionally, the “Final Stormwater Management Plan, Construction Drawing Review, and Permitting” phase is outlined in Appendix 12 “Watershed/Stormwater Management Permit Application Process” Flow Chart. 3. Construction and Construction Inspections of Stormwater Control Structures-BMP(s) The Construction and Construction Inspections of Stormwater Control Structures-BMP(s) Phase is outlined on Appendix 13, titled “Stormwater Management Construction and Construction Inspection Process.” Once the Watershed/Stormwater Permit is issued, construction may begin, provided all other environmental permits have been obtained, or are in the process of being obtained, and all requirements of the Town of Kernersville Community Development Department have been satisfied. During construction, Town staff may conduct periodic construction inspections of Stormwater BMP(s), however the designer is ultimately responsible to certify that any structural BMPs meet the requirements of the ordinance and Stormwater Permit. Certain BMP(s) (as Bio-retention Areas) should not be constructed until the drainage area to that BMP has been stabilized. Should a BMP be constructed prior to adequate ground stabilization provisions being implemented, the responsibility of reconstruction, replanting or replacement of any contaminated soils is the responsibility of the owner Upon completion of a project, and before a certificate of occupancy shall be granted, the applicant shall certify that the completed project is in accordance with the approved Stormwater Management Plan and design, and shall submit “as built” plans for all BMPs after final construction is completed to the Watershed Administrator. The plans shall show the final design specifications for all stormwater management facilities and practices and the field location, size, depth, and planted vegetation of all measures, controls, and devices, as installed. The designer of the stormwater management measures and plans shall also certify, under seal, that the as-built stormwater measures, controls, and devices are in compliance with the approved stormwater plans and designs and with the requirements of the Town of Kernersville’s applicable ordinances. Appendix 14 “Engineer’s Certificate of Stormwater Control Completion” contains a model that the Town of Kernersville has available for the convenience and use of designers. After review and approval by the Watershed Administrator of the BPM(s) As-built plans and Engineer’s Certificate of Stormwater Control Completion, and any other pending requirements; the owner may request release of fifty percent (50%) of the performance surety. Upon request by the owner, the Stormwater Division shall inspect the stormwater control structure(s) to determine that the stormwater control(s) have been constructed and maintained as required by the Town of Kernersville’s Stormwater and Watershed Ordinances. Watershed and Stormwater Administrative Manual 8 Revised 2020-02-01 The Stormwater Administrator, upon determining that the stormwater control(s) have been installed in conformity with the Town of Kernersville’s Stormwater and Watershed Ordinances and maintained properly, shall release fifty percent (50%) of the performance surety. No sooner than one year after the completion of the Stormwater control structure, BMP(s), the owner may request release of the remainder of the performance surety. Upon request by the owner, the Stormwater Division shall inspect the stormwater control structure(s) to determine that the stormwater control(s) are performing as required by the Town of Kernersville’s Stormwater and Watershed Ordinances. If the plantings or other features cannot be viewed due to time of year, plant dormancy or leaf cover, then the inspection may be delayed until such time as the inspection may be performed. The Stormwater Administrator, upon determining that the stormwater control(s) are performing as required by the Town of Kernersville’s Stormwater and Watershed Ordinances, and after any needed repairs to the stormwater control structure(s) are made by the owner, shall release the remaining performance surety. Upon default of the owner to construct, maintain, repair and, if necessary, reconstruct any structural BMP in accordance with the applicable permit or operation and maintenance agreement, the Town of Kernersville may use all or any portion of the performance surety to make necessary improvements based on an engineering estimate or bids. Such expenditure of funds shall only be made after requesting the owner to comply with the permit or maintenance agreement. In the event of a default triggering the use of installation performance surety, the Town of Kernersville shall not return any of the unused performance surety, which shall be retained for maintenance. If the Town of Kernersville takes action upon such failure by the applicant or owner, the Town of Kernersville may collect from the applicant or owner for the difference should the amount of the reasonable cost of such action exceed the amount of the performance surety held. V.STORMWATER CONTROL STRUCTURES (BMPs) INSPECTION PROGRAM Inspections and inspection programs by the Town of Kernersville may be conducted or established on any reasonable basis, including but not limited to routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; and joint inspections with other agencies inspecting under environmental regulations. Inspections may include, but are not limited to, reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in BMPs; and evaluating the condition of BMPs. If the owner or occupant of any property refuses to permit such inspection, the Stormwater Administrator shall proceed to obtain an administrative search warrant pursuant to G.S. 15-27.2 or its successor. No person shall obstruct, hamper or interfere with the Stormwater Administrator while carrying out his or her official duties. The Stormwater Administrator may notify the owner of any repair or reconstruction necessary to meet the requirements of the Town of Kernersville’s Stormwater and Watershed Ordinance All repair or reconstruction shall be in accordance with the approved plans and specifications for the stormwater control structure and the operation and maintenance plan and shall be completed within ninety (90) days after notification by the Stormwater Administrator. Upon request by the owner, the Watershed and Stormwater Administrative Manual 9 Revised 2020-02-01 Stormwater Administrator shall inspect and approve the completed repairs. Annual Maintenance Inspection and Reports by the Owner of the BMP(s) All stormwater control structures shall be inspected at least on an annual basis to determine that the controls are performing as required by the Town of Kernersville’s Stormwater and Watershed Ordinances. For stormwater control structures completed and approved by the Town of Kernersville after October 2007, the owner or person responsible for maintenance shall submit to the Stormwater Administrator an inspection report from a qualified registered North Carolina professional engineer, surveyor, soil scientist or landscape architect performing services only in their area of competence. The inspection report shall contain all of the following: The name and address of the land owner; The recorded book and page number of the lot of each structural BMP; A statement that an inspection was made of all structural BMPs; The date the inspection was made; A statement that all inspected structural BMP(s) are performing properly and are In compliance with the terms and conditions of the approved maintenance agreement required by the Town of Kernersville regulations. The original signature and seal of an engineer, surveyor, soil scientist or landscape architect who either has adequate training in BMP maintenance or has been certified to maintain BMPs. Homeowner’s and other associations required entering into an operation and maintenance agreement shall include a financial statement certifying compliance with the escrow account long term maintenance requirement. An original inspection report shall be provided to the Stormwater Administrator beginning one year from the date of as-built certification and each year thereafter on or before the date of the as-built certification.

WITNESSETH: 1.The TOWN under various state and federal laws, is required to regulate the maintenance of engineered Stormwater Control Measures and related structures (hereinafter referred to as “SCMs”) constructed to serve new or re-development within both the corporate limits of the TOWN and within the extra territorial zoning jurisdiction of the TOWN to ensure that, following initial construction, the SCMs are operated, maintained, and to the extent necessary, repaired in accordance with applicable state and federal laws. 2.The TOWN has determined that, to maintain the Town’s compliance under applicable state and federal regulations, certain obligations are to be met by the DEVELOPER and subsequent owners of the SCMs. 3.The DEVELOPER is the owner of certain lands as described in Deed Book _______, Page ________, in the Office of the Register of Deeds of Forsyth County, North Carolina upon which it is erecting and will make improvements, said development to be known as (hereinafter referred to as the "PROPERTY"). 4.The DEVELOPER desires to build SCMs to provide storage and treatment of stormwater runoff to serve the development on said PROPERTY, as required by the Kernersville Watershed Protection and Stormwater Ordinances (hereinafter referred to as "ORDINANCES"). 5. The DEVELOPER has applied to the TOWN for the issuance of a high density watershed/stormwater permit (hereinafter referred to as "PERMIT") to construct, maintain and operate the SCMs consistent with the approved plans and specifications on file at the office of the Watershed Administrator and the Operation and Maintenance Plan (ATTACHMENT A). 6.The DEVELOPER has conveyed unto the TOWN, or its successors or assigns, an Easement and Right-of-Way establishing the right of ingress, egress and regress over the PROPERTY for the purpose of inspection, repair, or maintenance of the SCMs. The Easement and Right-of-Way for the SCMs are described in Deed Book , Page , which is recorded in the Office of the Register of Deeds of Forsyth (or Guilford, if applicable) County, North Carolina. 7.The TOWN desires to assure that the SCMs on the PROPERTY are properly constructed, maintained and operated in accordance with law, the ORDINANCES, and PERMIT provisions in order to protect the quality of the waters of the State and the public interest therein. Watershed and Stormwater Administrative Manual 38 Revised 2020-02-01 APPENDIX 8. b 8.These SCMs are required to comply with the ORDINANCES and that failure to maintain the SCMs is a violation of the ORDINANCES potentially subjecting each lot owner of the PROPERTY to significant daily civil penalties and other enforcement actions. 9.After the completion of construction of the SCMs, the DEVELOPER may convey the SCMs to the ASSOCIATION. NOW, THEREFORE, in consideration of the promises and the benefits to be derived by each of the parties hereto, the TOWN, the DEVELOPER and the ASSOCIATION do hereby mutually agree as follows: 1.The DEVELOPER shall construct the SCMs in accordance with the ORDINANCES, PERMIT and plans and specifications hereafter issued and approved by the TOWN; and that DEVELOPER and ASSOCIATION assume specific maintenance, replacement, reconstruction and repair, responsibilities set forth in the ORDINANCES and with respect to the SCMs. 2.Construction and Maintenance of the SCMs: The DEVELOPER shall be responsible for the construction of the SCMs; and prior to conveying control of the SCMs, the DEVELOPER will be responsible for maintenance, repair, reconstruction, and replacement thereof. Following conveyance of the SCMs, the ASSOCIATION and its members will be responsible for maintaining the SCMs, their appurtenances and vegetation in the manner specified herein and in strict compliance with the ORDINANCES. At all times, the SCMs shall perform as designed and shall at all times comply with all applicable laws, ordinances, regulations, rules and directives of governmental authorities. 3.Ownership and/or Transfer of PROPERTY: Upon completion of the SCMs, the DEVELOPER has the option to convey that portion of the PROPERTY on which the SCMs are located to an Association to be formed for the purpose of administrating the provisions of a declaration of covenants to be imposed upon the PROPERTY, which declaration shall fully comply with all requirements of this contract as well as all applicable laws. The Declaration of Covenants, Conditions and Restrictions for PROPERTY, in reference to this contract and all applicable stormwater and watershed laws, shall be subject to review and approval by the Town of Kernersville Attorney. The DEVELOPER agrees that it shall not transfer ownership and/or control of the SCMs until construction has been completed in accordance with the PERMIT and approved plans and specifications; and as defined in the ORDINANCES, the TOWN has inspected and approved the SCMs. In addition, the DEVELOPER and ASSOCIATION and any new Owner must request that the PERMIT for the SCMs be re-issued to any subsequent Owner. The DEVELOPER and ASSOCIATION agree not to transfer, convey, assign or otherwise relinquish or release its responsibility for the operation and maintenance of its SCMs until a PERMIT has been re-issued to DEVELOPER and ASSOCIATION’s successor, or new owner at which time DEVELOPER and ASSOCIATION shall be released from any obligations hereunder arising from events or circumstances occurring after the date the SCMs are transferred and the PERMIT is reissued to the new Owner of the PROPERTY. 4.Cost Estimates for Construction of the SCMs: The DEVELOPER’s Engineer shall submit an estimate of construction costs for review and approval by the TOWN in accordance and regulations with the ORDINANCES. This cost estimate will be used to establish the level to which the escrow account shall be funded. 5.Establishment of an Escrow Account: For the purpose of insuring the availability of funds for the long term maintenance and/or replacement/reconstruction of the SCMs, an escrow account must be established, which can be spent solely for that purpose. Maintenance activities include, but are not limited to, sediment removal, and structural, biological or vegetative replacement, major repairs, or reconstruction. If the SCMs are not performing adequately or as intended or are not properly maintained, the TOWN in its sole discretion, may remedy the situation, and in such instances, the TOWN shall be fully reimbursed from the escrow account. Escrowed funds may be spent by the DEVELOPER, ASSOCIATION or ASSOCIATIONS’s successor for allowable expenses, provided that the TOWN shall first consent to the expenditure. Escrowed funds shall not be spent for routine landscaping maintenance items such as mowing. The escrow account will be funded initially by a lump sum contribution of the DEVELOPER (the “Initial Payment”), and thereafter by annual sinking funds paid by the ASSOCIATION, if it has taken ownership or by the DEVELOPER if it still retains ownership of the SCMs. The DEVELOPER shall deposit the Initial Payment in the escrow account and show proof of such payment: (i)Prior to plat recordation of the PROPERTY; or (ii)Before the issuance of building permits for the construction of improvements on the PROPERTY. Whichever occurs first. Watershed and Stormwater Administrative Manual 39 Revised 2020-02-01 The Initial Payment shall be equal to $ ________ dollars (which is equal to fifteen percent (15%) of the initial construction costs of the SCMs). The total sinking fund budget is defined as the amount required for the initial construction cost of the SCMs. The ASSOCIATION shall deposit funds at least annually in equal installments into the escrow account such that at least two -thirds (2/3) of the total amount of the sinking fund budget, as set in the ORDINANCES, shall be deposited into the escrow account within the first five (5) years and the full amount shall be deposited within ten (10) years following initial construction of the SCMs. A portion of the annual assessments of the ASSOCIATION shall include an allocation into the escrow account. Any funds drawn down from the escrow account shall be replaced in accordance with the schedule of anticipated work used to create the sinking fund budget. 6.The DEVELOPER shall provide in an Operation and Maintenance Plan (ATTACHEMENT A) that specifies all necessary operation and maintenance procedures and that the SCMs, appurtenances and access easements thereto shall thereafter be properly maintained and operated in conformity with ORDINANCES and the provisions of the PERMIT. 7.The DEVELOPER and its successors shall grant to the TOWN a right of entry to inspect, monitor, maintain, repair, and reconstruct SCMs. 8.The DEVELOPER and its successor hereby authorize the TOWN to recover from the DEVELOPER or ASSOCIATION and its members, whichever is the responsible party, any and all costs the TOWN expends to maintain or repair the SCMs or to correct any operational deficiencies. Failure to pay the TOWN all of its expended costs, after forty-five days written notice, shall constitute a breach of the agreement. The TOWN shall thereafter be entitled to bring an action against the responsible party to pay, or foreclose upon the lien hereby authorized by the agreement against the PROPERTY, or both, in case of a deficiency. Interest, collection costs, and attorney fees shall be added to the recovery. 9.This Agreement shall not obligate the TOWN to maintain or repair any SCMs, and the TOWN shall not be liable to any person, firm, partnership, company, corporation, governmental agency, Association or entity for the condition or operation of SCMs. 10.This agreement shall not in any way diminish, limit, or restrict the right of the TOWN to enforce any of its ordinances as authorized by law. 11.Indemnification: Owners, DEVELOPER and/or ASSOCIATION agree to protect, defend, indemnify and hold the TOWN, its officers, employees and agents free and harmless from and against any losses, penalties, damages, settlements, costs, charges, professional fees or other expenses or liabilities in connection with or arising out of this Agreement and/or related to the SCMs, unless the TOWN has agreed in writing to assume the maintenance responsibility for the SCMs and has accepted dedication of any and all rights necessary to carry out that maintenance. 12.A copy of this Operation and Maintenance Agreement shall be filed at the Forsyth (or Guilford, ifapplicable) County Register of Deeds and in the office of the Watershed Administrator.

Witness my hand and notarial seal, this the day of , 20 . My Commission Expires: Notary Public Watershed and Stormwater Administrative Manual 46 Revised 2020-02-01 EXHIBIT A PROPERTY DESCRIPTION (PER DEED) Watershed and Stormwater Administrative Manual 47 Revised 2020-02-01 Operation and Maintenance Plan: “Name of the Pond or development” : Wet Detention Pond Dam Safety Preserving the structural integrity of the wet detention pond's dam is important in protecting downstream life and property. There are at least four aspects of the dam that require specific attention: (1) assessment of hazard potential due to changes in downstream development; (2) leakage and seepage; (3) dam material problems; and (4) vegetation growth on the dam embankments. Assessment of Hazard Potential Before any dam is constructed, the design engineer is responsible for notifying the NC State Dam Safety Office of the proposed dam. If the dam falls under State Dam Safety jurisdiction, the dam must be constructed, maintained, and operated according to their design and construction guidelines. Even if the dam does not fall under the NC Dam Safety Office’s jurisdiction, the dam should be designed and constructed in accordance with current proper engineering practices. The City has requirements concerning the maintenance of dams associated with required wet detention ponds. As new development occurs downstream of the pond, the chance of significant property damage or danger to human life may increase if catastrophic failure of the dam occurs. Although the dam may be initially exempt from regulation by the State, the owner is responsible for reporting to the State Dam Safety Office downstream development that may affect the hazard classification of the dam. Leakage and Seepage The downstream side of the dam should be inspected regularly for evidence of significant leakage or seepage. Seepage can emerge anywhere below the normal pool elevation, including the downstream slope of earth dams, areas beyond the toe of the dam, and around the spillway or pond outlet conduit. Indications of significant seepage include areas where the soil is saturated or where there is a flowing “spring” or leak. If “sinkholes” in the dam embankment are noticed, or if constant flowing water is noticed on the downstream side of the dam, then seepage has become excessive and professional engineering advice should be sought immediately to avert a major structural problem or a catastrophic failure of the dam. Dam Material Problems For earthen dams, pronounced cracks on the embankment surface indicate the first stages of potential dam failure. Transverse cracks (running perpendicular to the embankment face) generally indicating differential settlement of the dam, can provide pathways for excessive seepage. Longitudinal cracks (running parallel to the embankment face) may be due to inadequate compaction of the dam during construction or shrinkage of the clay (desiccation) in the top of the embankment during prolonged dry conditions. These cracks may eventually lead to slope failure, such as sliding or sloughing. For reinforced concrete dams, the concrete should be checked for pronounced cracking, leakage from the joints, and displacement (noticeable Watershed and Stormwater Administrative Manual 48 Revised 2020-02-01 APPENDIX 10. a leaning or bulging). Also, excessive seepage, leakage, or springs just downstream of the concrete dam could be indicative of potential seepage-related “piping” problems under the dam. If such problems or other structural problems are observed, professional engineering advice should be sought. Vegetative Growth Trees and other woody vegetation are not permitted on the top, slopes, or embankments of earthen dams. Large root systems from woody vegetation can weaken the dam structure and provide seepage pathways. Thick vegetative cover can also provide a haven for burrowing animals such as groundhogs and muskrats. These animals can create a network of burrows in the dam embankments that can significantly weaken the dam, by creating seepage paths, which may eventually lead to dam failure. Mowing of the dam embankments should occur, at a minimum, once every 6 months to prevent woody vegetation from becoming established. Pollution Prevention Activities To assist the wet detention pond in improving the quality of stormwater runoff, every effort should be made to reduce the pollutant load entering the pond system. The following onsite efforts should be made to reduce pollutants from entering the pond: •Outside trash dumpsters should be kept covered, and the area around the dumpster should be kept neat and clean. •Chemicals, petroleum products, and other pollution sources (such as machinery) should be stored in a covered area away from possible stormwater contact. Spent chemicals are to be properly disposed or recycled. •Fertilizers and pesticides should be used conservatively on the property grounds. Excessive amounts of these chemicals can be washed away with stormwater runoff, increasing the nutrient load to the pond. •Chemicals such as copper sulfate used to inhibit algal growth in the pond degrade water quality. Since the pond’s main function is to enhance water quality, these chemicals should not be used. Rather, reducing the amount of fertilizer application and ensuring that the pond outlets are properly functioning so the pool is flushed periodically will help to deter algal growth. •Trash and vegetative floatables (grass clippings, leaves, limbs, etc.) should be cleaned from the pond surface and surroundings periodically to promote a healthy, aesthetically pleasing environment, and to prevent blockage of the pond outlets. Studies have shown that people are less likely to litter ponds that are aesthetically pleasing and support wildlife. Stabilization of Wet Detention Pond Drainage Area The area draining to the wet detention pond should remain stabilized to prevent excessive sediment from entering the pond. When bare soil is directly exposed to precipitation, the sediment concentration in runoff is much higher than for soil that is covered and stabilized. A stabilized area is covered by impervious surfaces (pavement, buildings), grass cover, landscaping (mulch, pine straw), etc. It is in the best interest of the pond owner to reduce onsite sediment runoff to the pond, as this will reduce the life span of the pond and result in the need for more periodic, expensive dredging. Embankments If pond embankments are not kept well vegetated with grasses, erosion may occur. Erosion can be repaired by filling the small channels and gullies with suitable soil, compacting, and seeding. It may be necessary to install temporary erosion control (such as hay bales) along heavily eroded areas to allow the repaired areas to stabilize. It is especially important to inspect for and Watershed and Stormwater Administrative Manual 49 Revised 2020-02-01 immediately repair any erosion on the dam embankments. Pipe Inlet and Outlet areas Where erosion causes the undercutting of the downstream end of pipe, the undercut should be stabilized immediately to prevent the end pipe section from “breaking” off. Eroded areas should be filled with good compactable soil and covered with geotextile fabric and rip-rap. Open Channel Flow Eroded areas should be seeded/sodded and protected with temporary velocity dissipation (such as excelsior matting, straw bales, etc.). If erosion continues, a more robust lining should be used. Blockage of Outlets Wet detention ponds are designed for the water to exit the pond through the low flow orifice(s), the principal spillway, and the emergency spillway. It is important to check all three outlets for blockage that would impair the pond’s water quality and hydraulic functionality. Low Flow Orifice(s) Unless an inverted orifice is used, some type of trash guard is to be maintained over the low flow orifice(s) to prevent clogging. When the orifice becomes clogged the water level rises to the principal spillway elevation and the benefits associated with temporary storage and its gradual release are lost. To preserve “extended detention” the low flow orifice should be inspected for blockage monthly, or after every runoff-producing rainfall event. Principal and Emergency Spillway Principal and emergency spillways are designed to safely convey one-inch rainfall events, and those larger storms that produce runoff which exceed the water quality volume of the wet detention pond. If these spillways are blocked so they do not operate at full capacity, the risk of dam overtopping or other uncontrolled releases may result. To ensure the hydraulic capacity of the spillways, the spillways should be inspected for blockage monthly, or after every runoffproducing rainfall event. If a riser/barrel is used for the principal spillway, a trash rack is to be maintained on the riser. Vegetative growth in the riser should be removed promptly so that the design capacity of the spillway is maintained. The emergency spillway and outlet area where the barrel projects from the fill slope should be clear of woody vegetation, tree limbs, sediment accumulation, etc. Sediment Accumulation To preserve the wet detention pond’s pollutant removal capability, sediment must be removed in areas where the capacity of the design sediment storage volume has been exceeded. The pond forebay helps to improve the removal efficiency of the pond system by trapping the majority of coarser suspended solids behind a rock baffle. When sediment deposition in the forebay exceeds the designed sediment storage capacity for the forebay, the forebay must be dredged. Typically, forebays will need to be dredged every 5 to 10 years. Depth measurements relative to the normal surface elevation (bottom of water quality orifice) should be taken at several locations around the pond. The sediment is to be removed when the measured depth is less than the design permanent water depth. Most wet detention ponds are designed for a three to four foot permanent water depth. As sediment accumulates in the pond, the permanent water depth is reduced along with the pond's ability to treat pollutants in the runoff. If a forebay is used at the inlet area of the pond Watershed and Stormwater Administrative Manual 50 Revised 2020-02-01 and is regularly dredged, the frequency of dredging the entire pond could be greatly reduced. Check water depth at various points in the pond semi-annually. If depth is reduced to 75 % of the original design depth, sediment must be removed to at least the original design depth. Sediment from most sources is usually not hazardous or contaminated, however, it is very “soupy” and is difficult to manage. It is good idea to provide a storage area near the wet detention pond to place sediment once it is dredged to allow it to dry. If desired, sediment may be land applied and seeded, while following all pertinent soil and erosion control regulations. If land applied on-site, it should be within the drainage area to the pond so sediment that runs off can be recaptured. Wet Detention Pond Maintenance Routine Maintenance Routine maintenance shall include minor upkeep such as mowing; trash and debris removal; minor slope repair and stabilization; periodic structural inspections of the valves, gates, dam, etc.; and tree and brush removal from the dam, spillway, inlet(s), and outlet. These maintenance items may be performed by the owner without review of a Professional Engineer. Non-Routine Maintenance Non-routine maintenance shall include such items as sediment clean-out (dredging); channel stabilization; and problems regarding the principal spillway conduits, emergency spillway, dam failure, and seepage. These items require a Registered Professional Engineer to prepare a plan and/or details and to certify completion of the maintenance. All revisions and repairs to permanent runoff control structures shall be done in accordance with Town of Kernersville guidelines and specifications. Maintenance Schedule: (estimated schedule - certain ponds may require more or less frequent Attention). I.Monthly, or after every runoff-producing rainfall event. A. Remove trash and debris from the trash rack. B. Check and clear the orifice of any obstructions. C. Check the pond side slopes for erosion and remove trash from around the pond. D. Inspect principal and emergency spillways for blockage. II.Quarterly, or after major storm events (more than 2 inches of rain). A. Inspect the collection system (e.g. catch basins, piping, grassed swales) for proper functioning. Clear accumulated trash from basin grates and basin bottoms, and check piping for obstructions. B. Check pond inlet pipes for undercutting, replace rip-rap that is choked with sediment, and repair broken pipes. C. Check the operation of the gate valve. All valves should be operated from the fully closed to the fully open position. D. Remove woody vegetation (trees and brush) from dam embankment surfaces and spillway(s). III.Semi-Annually Watershed and Stormwater Administrative Manual 51 Revised 2020-02-01 A. Remove accumulated sediment from the bottom of the outlet structure. B. Check for presence of rip-rap at inlet pipes and replace if necessary. C. Check pond depth at various points in the pond. If mean depth is reduced to 75 % of the original design depth, sediment will be removed to at least the original design depth. D. Check riser and barrel for improper alignment, elongation and displacement of joints, cracks, leaks, loss of protective coating, corrosion, and blockage - repair as necessary. IV.General A. Mow side slopes according to the season. Maximum grass height should be nine (9) inches. B. Riparian and aquatic vegetation (willows, alders, cattails, etc.) are encouraged along the perimeter of the pond at the water's edge. However, the dam, emergency spillway, inlet(s), and water control structure should be kept clear of all woody vegetation. C. In case the ownership of the pond should change, the current owner should, within thirty (30) days of transfer of ownership, notify the Town of Kernersville, Stormwater Division of such ownership transfer. D. Excessive plant growth, algae blooms, odors, discoloration, perceived animal pests, etc. should be addressed with the Stormwater Division on an as-needed basis. Solutions to these problems should be non-chemical and deemed safe to our drinking water supply. Any and all amendments to this Operation and Maintenance Plan shall first be submitted to and approved by Town of Kernersville Stormwater Division.

Place notary seal below this line: Notary Public Print/Type Name: My Commission Expires: Watershed and Stormwater Administrative Manual 59 Revised 2020-02-01 (Name of the Bio-Cell) BIORETENTION AREA OPERATION AND MAINTENANCE PLAN The goals of this O&M Plan for a BMP structure is to specify all operation and maintenance work necessary for the storm water control structure(s) and to provide guidance to the current and any subsequent property owner on the requirements for BMP inspection and maintenance. Also provide an estimation of the Annual Budget and Replacement Fund necessary for the annual operation, inspection and maintenance activities for the BMP. Effective long-term operation of infiltration practices requires a dedicated and routine maintenance inspection schedule with clear guidelines and schedules, as shown later in this Plan. Where possible, facility maintenance should be integrated into routine landscaping maintenance tasks. The filter media and surface cover are the two most important elements of a Bioretention facility in terms of long-term performance. Common Maintenance Issues Bioretention facilities require plant, soil, mulch, and under-drain maintenance to ensure optimal infiltration, storage, and pollutant removal capabilities. Bioretention maintenance requirements are typical landscape care procedures and include: 1. Watering: Plants should be selected to be tolerant of the bioretention facility’s particular conditions. Watering should not be required after establishment (about 2 to 3 years). However, watering may be required during prolonged dry periods after plants are established. 2. Erosion Control: Inspect flow entrances, ponding area, and surface overflow areas periodically. Replace soil, plant material, and/or mulch in areas where erosion has occurred. Erosion problems should not occur with proper design except during extreme weather events. If erosion problems do occur, the following issues should be re-assessed: flow volumes from the contributing drainage area and bioretention size; flow velocities and gradients within the bioretention facility; flow dissipation and erosion protection methods in the pretreatment and in-flow areas. If sediment is deposited in the bioretention facility, immediately determine the source, remove excess deposits, and correct the problem. 3. Plant Material: Depending on plants selected and aesthetic requirements, occasional pruning and removal of dead plant material may be necessary. Watershed and Stormwater Administrative Manual 60 Revised 2020-02-01 APPENDIX 10. b Replace all dead plants. However, if specific plants consistently have a high mortality rate, assess the cause and replace with appropriate species. Periodic weeding is necessary until groundcover plants are established. Weeding should become less frequent if an appropriate plant density has been used. 4. Nutrients and Pesticides: The soil media and plant material should have been selected for optimum fertility, plant establishment, and growth within the particular conditions of each bioretention facility. Nutrient and pesticide inputs should NOT be required and will degrade the pollutant processing capability of the bioretention facility, as well as contribute to additional pollutant loading to receiving waters. By design, bioretention facililities are typically specified in watersheds where phosphorous and nitrogen levels are often elevated. Therefore, these should not be limiting nutrients with regard to plant health. If in question, have the soil analyzed for fertility. 5. Mulch: Bioretention areas should be mulched once the planting of trees and shrubs has occurred. Replace mulch annually in Bioretention facilities where heavy metal deposition is likely (e.g., drainage areas that include commercial/industrial uses, parking lots, or roads). In residential or other settings where metal deposition is not a concern, replace or add mulch as needed to maintain a 2 to 4 inch depth at least once every two years. 6. Soil media: Soil mixes for bioretention facilities are design to maintain long-term fertility and pollutant processing capability. Estimates from metal attenuation research indicates that metal accumulation should not present a toxicity concern for at least 20 years in bioretention facilities (USEPA 2000). Further, replacing mulch where heavy metal deposition is likely provides an additional factor of safety for prolonged bioretention performance. If in question, have soil analyzed for fertility and pollutant levels. With soil testing the accumulation of toxins and heavy metals can be detected or prevented. Over a period of time, heavy metals and other toxic substances will tend to accumulate in the soil and the plants. Data from other environs such as forest buffers and grass swales suggest accumulation of toxins and heavy metals within five years of installation. However, there is no methodology to estimate the level of toxic materials in the bioretention areas since runoff, soil, and plant characteristics will vary from site to site. As the toxic substances accumulate, the plant biologic functions may become impaired, and the plant may experience dwarfed growth followed by mortality. The biota within the soil can also become void and the natural soil chemistry may be altered. The preventative measures would include the removal of the contaminated soil. In some cases, removal and disposal of the entire soil base as well as the plant material may be required. When the filtering capacity diminishes substantially (e.g., when water ponds on the Watershed and Stormwater Administrative Manual 61 Revised 2020-02-01 surface for more than 12 hours), remedial actions must be taken. One possible problem is that underdrain pipe systems can become clogged. Annual flushing through pipe cleanouts is recommended to facilitate unclogging of the pipes without disturbing the bioretention areas. If the water still ponds for more than 12 hours, the top few inches of material should be removed and replaced with fresh material. The removed sediments should be disposed of in an acceptable manner (e.g., landfill). If that does not solve the problem, more extensive rebuilding is required. Examples of When to Perform Maintenance • Replace gravel when it has become clogged with sediment. • Remove top layer of fill media when the pool does not drain quickly. The pool is normally designed to drain within 12 hours. Sample Operation and Maintenance Provisions Important operation and maintenance procedures: −Immediately after the Bioretention cell is established, the plants will be watered twice weekly if needed until the plants become established (commonly six weeks). −Snow, mulch or any other material will NEVER be piled on the surface of the Bioretention cell. −Heavy equipment will NEVER be driven over the Bioretention cell. −Special care will be taken to prevent sediment from entering the Bioretention cell. −Once a year, a soil test of the soil media will be conducted. After the Bioretention cell is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Ongoing monitoring and maintenance is vital to the overall success of bioretention areas. Annual maintenance will be required for plant material, mulch layer, and soil layer. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
