General Requirements A. Plan Approval Required: No person shall undertake any land-disturbing activity subject to this Ordinance that uncovers an acre, or more than one acre, without first having an erosion control Plan approved by the County. No land-disturbing activity may be initiated until the County is notified of the date that the land-disturbing activity will begin. B. Protection of Property: Persons conducting land-disturbing activity shall take measures to protect all public and private property from damage caused by sedimentation and erosion damage caused by land-disturbing activities. C. More Restrictive Rules Shall Apply: Whenever conflicts exist between Federal, State, or local laws, Ordinance, or rules, the more restrictive provision shall apply. D. Plan Approval Exceptions: Notwithstanding the general requirement to obtain a Plan approval prior to undertaking land-disturbing activity, a Plan approval shall not be required for land-disturbing activity, that does not exceed 43,560 square feet in surface area and is not considered a part of a common plan of development. In determining the area, lands under one or diverse ownership being developed as a unit will be aggregated. E. Building Permits: No building permit, unless excluded by Section 8.17, Permits, shall be issued without an erosion control sign-off pursuant to N.C.G.S. 160D-1110. [05-03- 2021] F. Inspections: Any and all applicable intermediate inspections may be held in any trade (building, mechanical, electric, and/or plumbing) if any land-disturbing activity, on a tract, including single family residences, is found not to be in compliance with any part of this Ordinance. G. Building Finals: Building finals and/or certificates of occupancy may not be issued if any land-disturbing activity, including single-family residences, is found not to be in compliance with any part of this Ordinance. Section 8.6. Basic Control Objectives A. An erosion and sedimentation control Plan may be disapproved pursuant to Section 8.18, Erosion and Sedimentation Control Plans, if the Plan fails to address the following control objectives: 1. Identify critical areas: On-site areas which are subject to accelerated erosion, and off-site areas vulnerable to damage from erosion and/or sedimentation are to be identified and receive special attention. 2. Limit time of exposure: All land-disturbing activity is to be planned and conducted to limit exposure to the shortest feasible time specified in G.S. 113A- 57 or as directed by the approving authority. 3. Limit exposed area: All land-disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time. 4. Control surface water: Surface water runoff originating upgrade of exposed areas should be controlled to reduce erosion and sediment loss during the period of exposure. Unified Development Ordinance | New Hanover County, NC 8-7 5.Control sedimentation: All land-disturbing activity is to be planned and conducted so as to prevent off-site sedimentation damage. 6.Manage stormwater runoff: Plans shall be designed so that any increase in velocity of stormwater runoff resulting from a land-disturbing activity will not result in accelerated erosion of the receiving stormwater conveyance or at the point of discharge. Plans shall include measures to prevent accelerated erosion within the project boundary and at the point of discharge. B.Preconstruction conferences are optional. In the event, a preconstruction conference is required, it must be included on the plan. C.No person may initiate a land-disturbing activity before notifying the County of the date that land-disturbing activity will begin and when the initial erosion control measures are installed. D.A Plan approval issued under this Ordinance shall be prominently displayed at either the primary entrance of the job site or at another location that is observable to the public and inspectors until all construction is complete, all permanent sedimentation and erosion control measures are installed, and the site has been stabilized. A paper copy of the approved Plan shall be kept on file at the job site. Section 8.7. Mandatory Standards for Land-Disturbing Activity No land-disturbing activity subject to the control of this Ordinance shall be undertaken except in accordance with G.S. 113A-57 and the following mandatory standards: A.Buffer Zone: 1.No land-disturbing activity during periods of construction or improvement to land shall be permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within 25% of the buffer zone nearest the land-disturbing activity. This subdivision shall not apply to a land-disturbing activity in connection with the construction of facilities to be located on, over, or under a lake or natural watercourse. 2.The width of a buffer zone shall be measured horizontally from the edge of the water to the nearest edge of the disturbed area, with the 25% of the strip nearest the land-disturbing activity containing natural or artificial means of confining visible siltation. B.Graded Slopes and Fills: The angle for graded slopes and fills shall be no greater than the angle that can be retained by vegetative cover or other adequate erosion control devices or structures. The angle for graded slopes and fills must be demonstrated to be stable. Stable is the condition where the soil remains in its original configuration, with or without mechanical restraints. In any event, slopes left exposed shall, within 21 calendar days of completion of any phase of grading, be planted or otherwise provided with temporary or permanent ground cover, devices, or structures sufficient to restrain erosion. C.Fill Material: Unless a permit from the Department’s Division of Waste Management to operate a landfill is on file for the official site, acceptable fill material shall be free of organic or other degradable materials, masonry, concrete and brick in sizes exceeding 8-8 New Hanover County, NC | Unified Development Ordinance 12 inches, and any materials which would cause the site to be regulated as a landfill by the State of North Carolina. D. Ground Cover: Whenever land-disturbing activity that will disturb one or more than one acre is undertaken on a tract, the person conducting the land-disturbing activity shall install such sedimentation and erosion control devices and practices that are sufficient to retain the sediment generated by the land-disturbing activity within the boundaries of the tract during construction upon and development of said tract, and shall plant or otherwise provide a permanent ground cover sufficient to restrain erosion after completion of construction or development. Except as provided in Section 8.8.B.5 of this Ordinance, provisions for a ground cover sufficient to restrain erosion must be accomplished within 90 calendar days following completion of construction or development. E. Prior Plan Approval: No person shall initiate any land-disturbing activity that will disturb one or more than one acre on a tract unless, 30 or more days prior to initiating the activity, an erosion and sedimentation control Plan for the activity has been both filed with and approved by the County pursuant to G.S. 113A-57(4) and G.S. 113A-54(d)(4). The land-disturbing activity shall be conducted in accordance with the approved Plan once the Plan has been approved. F. All individuals that obtain a locally-approved erosion and sedimentation control plan that disturbs one acre or more of land, are required by the U.S. Environmental Protection Agency to obtain coverage under the N. C. Department of Environmental Quality Construction General Permit No. NCG010000 (NCG01). The requirements in NCG01 for temporary or permanent ground cover, or stabilization requirements, may differ from the ground cover, or stabilization, requirement in this Ordinance. It is the responsibility of the person conducting the land-disturbing activity to ensure compliance with the NCG01. Section 8.8. Design and Performance Standards A. Except provided in Subsection B.2 of this Section, erosion and sedimentation control devices and structures shall be planned, designed and constructed as to provide protection from the calculated maximum peak rate of runoff from the 10-year storm that produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture, Natural Resources Conservation Services “National Engineering Field Handbook 630 for Conservation Practices”. B. In High Quality Water (HQW) zones, the following design standards shall apply: 1. Uncovered areas in HQW zones shall be limited at any time to a maximum total area of 20 acres within the boundaries of the tract. Only the portion of the land- disturbing activity within a HQW zone shall be governed by this section. Larger areas may be uncovered within the boundaries of the tract with the written approval of the Director upon providing engineering justification with a construction sequence that considers phasing, limiting exposure, weekly submitted self-inspection reports, and more conservative design than the 25-year storm. The Director may also stipulate the inclusion of other conditions in the plan as necessary, based on specific site conditions. 2. Erosion and sedimentation control devices, and structures within HQW zones shall be so planned, designed, and constructed to provide protection from the runoff of the 25-year storm that produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Unified Development Ordinance | New Hanover County, NC 8-9 Agriculture, National Resources Conservation Services “National Engineering Field Handbook 630 for Conservation Practices”. Other methodologies may be used if based on generally accepted engineering standards that are shown to the County to be equivalent to or improved over the procedures in Handbook 630. The County shall determine acceptability of an alternative methodology based upon a showing that the runoff model was based on observed data in agreement with the predictive model. 3. In order to provide for water quality protection in the HQW zones, sediment basins that discharge to those areas shall be designed and constructed to meet the following criteria: a. Use a surface withdrawal mechanism, except when the basin area is less than 1 acre; b. Have a minimum of 1,800 cubic feet of storage area per acre of disturbed area; c. Have a minimum surface area of 325 square feet per cfs of Q25 peak inflow; d. Have a minimum dewatering time of 48 hours; and e. Incorporate 3 baffles, unless the basin is less than 20 feet in length, in which case 2 baffles shall be sufficient. 4. Newly constructed open channels in HQW zones shall be designed and constructed with side slopes no steeper than two horizontals to one vertical if a vegetative cover is used for stabilization, unless soil conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices, structural devices, or other forms of ditch liners proven to the County as being effective in restraining accelerated erosion. The angle for side slopes shall be sufficient to restrain accelerated erosion. 5. Upon a written request of the applicant, the Director may allow alternative design or control measures in lieu of meeting the conditions required in Subparagraph 3(b) through 3(e) of this Section if the applicant demonstrates that meeting all of those conditions will result in design or operational hardships and that the alternative measures will provide an equal or more effective level of erosion and sedimentation control on the site. Alternative measures may include, quicker applications of ground cover, use of sediment flocculants, and use of enhanced ground cover practices. Section 8.9. Stormwater Outlet Protection A. Intent: Stream banks and channels downstream from any land-disturbing activity shall be protected from increased degradation by accelerated erosion caused by increased velocity of runoff from the land-disturbing activity. B. Performance Standards: Persons shall provide a design and conduct land-disturbing activity so that the post-construction velocity of the 10-year storm runoff in the receiving watercourse to, and including the discharge point, does not exceed the greater of: 1. The velocity established by the Maximum Permissible Velocities table in subsection E of this section; or 8-10 New Hanover County, NC | Unified Development Ordinance 2. The projected velocity of the 10-year stormwater runoff in the receiving stormwater conveyance prior to development. C. Acceptable Management Measures: Measures applied alone or in combination to satisfy the intent of this section are acceptable, if there are no objectionable secondary consequences. The County recognizes that the management of storm- water runoff to minimize or control downstream channel and bank erosion is a developing technology. Innovative techniques and ideas will be considered and may be used when shown to have the potential to produce successful results. Some alternatives, while not exhaustive, are to: 1. Avoid increases in stormwater discharge velocities by designing measures to promote infiltration to compensate for increased runoff from areas rendered impervious; or 2. Avoid increases in stormwater discharge velocities by using vegetated or roughened swales and waterways in place of closed drains and high-velocity paved sections; or 3. Provide energy dissipaters at outlets of storm drainage facilities to reduce flow velocities to the point of discharge; These may range from simple rip-rapped sections to complex structures; or 4. Protect stormwater conveyance subject to accelerated erosion by improving cross sections or providing erosion-resistant lining; and 5. Upgrade or replace the receiving device structure, or stormwater conveyance such that it will receive and conduct the flow to a point where it is no longer subject to degradation from the increased rate of flow or increased velocity; D. Exceptions: This rule shall not apply where it can be demonstrated to the County that stormwater discharge velocities will not result in accelerated erosion in the receiving stormwater conveyance or discharge point. E. Maximum Permissible Velocities: The following is a table for maximum permissible velocity for storm water discharges in feet per second (F.P.S.) and meters per second (M.P.S.): Material F.P.S. M.P.S. Fine sand (non-colloidal) 2.5 0.8 Sandy loam (non-colloidal) 2.5 0.8 Silt loam (non-colloidal) 3.0 0.9 Ordinary firm loam 3.5 1.1 Fine gravel 5.0 1.5 Stiff clay (very colloidal) 5.0 1.5 Graded, loam to cobbles (non-colloidal) 5.0 1.5 Graded, silt to cobbles (colloidal) 5.5 1.7 Alluvial silts (non-colloidal) 3.5 1.1 Alluvial silts (colloidal) 5.0 1.5 Course gravel (non-colloidal) 6.0 1.8 Cobbles and shingles 5.5 1.7 Shales and hard pans 6.0 1.8 Unified Development Ordinance | New Hanover County, NC 8-11 Material F.P.S. M.P.S. Source: Adapted from recommendations by Special Committee on Irrigation Research, American Society of Civil Engineers, 1926, for channels with straight alignment. For sinuous channels, multiply allowable velocity by 0.95 for slightly sinuous, by 0.9 for moderately sinuous channels, and by 0.8 for highly sinuous channels. Section 8.10. Borrow and Waste Areas When the person conducting the land-disturbing activity is also the person conducting the borrow or waste disposal activity, areas from which borrow is obtained and which are not regulated by the provisions of the Mining Act of 1971; Article 7 of Chapter 74 of the General Statutes, and waste areas for surplus materials other than landfills regulated by the Department’s Division of Waste Management shall be considered as part of the land-disturbing activity. When the person conducting the land-disturbing activity is not the person obtaining the borrow and/or disposing of the waste, these areas shall be considered a separate land- disturbing activity. Section 8.11. Access and Haul Roads Temporary access and haul roads, other than public roads, constructed or used in connection with any land-disturbing activity shall be considered a part of such activity. Section 8.12. Operations in Lakes, Natural Watercourses Land-disturbing activity in connection with construction in, on, over or under a lake or natural watercourse shall be planned and conducted in such a manner as to minimize the extent and duration of disruption of the stream channel. Where relocation of a stream forms an essential part of the proposed activity, the relocation shall minimize changes in the stream flow characteristic. Section 8.13. Responsibility for Maintenance During the development of a site, the person conducting the land-disturbing activity shall install and maintain all temporary and permanent erosion and sedimentation control measures as required by the approved plan, or any provision of this Ordinance, the Act, or any order adopted pursuant to the Ordinance or the Act. After site development, the land owner or person in possession or control of the land shall install and/or maintain all necessary permanent erosion and sediment control measures, except those measures installed within a road or street right-of- way or easement, accepted for maintenance by a governmental agency. Section 8.14. Restoration of Areas Affected by Failure to Comply The County may require a person who engaged in a land-disturbing activity and failed to retain sediment generated by the activity, as required by G.S. 113A-57(3), to restore the waters and land affected by the failure so as to minimize the detrimental effects of the resulting pollution by sedimentation. This authority is in addition to any other civil or criminal penalty or injunctive relief authorized under this Ordinance. 8-12 New Hanover County, NC | Unified Development Ordinance Section 8.15. Additional Measures Whenever the County determines that accelerated erosion and sedimentation continues as a result of land-disturbing activity, despite installation of protective practices and maintenance of protective practices, the person conducting the land-disturbing activity will be required to and shall take additional protective action necessary to achieve compliance with the conditions specified in this Ordinance or the Act. Section 8.16. Areas Not Otherwise Covered Notwithstanding previous provisions, when it is determined that severe off-site erosion and/or sedimentation has occurred as a result of any land-disturbing activity, regardless of the size of the site, and despite application and maintenance of protective practices, remedial action shall be taken within a reasonable time period after notification. A notice shall be served upon that person by any means authorized under G.S. 1A-1 Rule 4. The notice shall specify a date by which the person must comply with the Ordinance or rules adopted by this Ordinance. Any person who fails to comply within the time specified is subject to additional civil and criminal penalties for a continuing violation as provided by this Ordinance. Section 8.17. Permits A.No person shall undertake any land-disturbing activity subject to this Ordinance without first obtaining a hardcopy or electronic permit from the County, except that no permit shall be required for any land-disturbing activity: 1.For the purpose of fighting fires; 2.For the stock piling of raw or processed sand, stone or gravel in material processing plants and storage yards, provided that sediment control measures have been utilized to protect against off-site damage; or 3.That does not exceed 43,560 square feet in surface area. In determining the area, lands under one or diverse ownership being developed as a unit will be aggregated. (Note: This exclusion from permits should allow land-disturbing activities for construction of a single-family residence on a single lot, but may not exceed one acre or be part of a common plan of development). B.The County may establish a fee schedule for the review and approval of erosion control Plans. In establishing the fee schedule, the County shall consider the administrative and personnel cost incurred by the department for reviewing the Plans and for related compliance activities. C.The permit fees as seen in Table 8.17.C include review and land disturbance fees: Unified Development Ordinance | New Hanover County, NC 8-13 Residential Review $200 New Projects (Paid at time of application) $200 Active Projects (Adding new acreage) $200 Previously permitted inactive projects (With modification) Land Disturbance $300 per acre disturbed or any increment of an acre. Due prior to Plat Recordation. Builders in a subdivision with active permits where the developer previously paid review and land-disturbing fees will not owe fees. Commercial Review $200 New Projects (Paid at time of application) $200 Active Projects (Adding new acreage) $200 Previously permitted inactive projects (With modification) Land Disturbance $300 per acre disturbed or any increment of an acre. Due prior to issuance of a Certificate of Occupancy. Other Review $200 (Paid at time of application) Land Disturbance $300 per acre or increment of an acre. Due prior to issuance of the land-disturbing permit D. Permits will expire one year from the date of issue if no construction activity begins on site. If activity ceases on a permitted site for a period of 12 months, the permit will expire. Section 8.18. Erosion and Sedimentation Control Plans A. An erosion control Plan shall be prepared for all land-disturbing activities subject to this Ordinance whenever the proposed activity will disturb one or more than one acre on a tract. The Plan shall be filed with the County Engineering Department, the New Hanover Soil and Water Conservation District, and for areas outside municipal corporate limits, the County Planning Department, at least 30 days prior to the commencement of the proposed activity. B. Persons conducting land-disturbing activity on a tract which covers one or more than one acres shall file three copies of the erosion control Plan or a digital copy, with the County at least 30 days prior to beginning such activity and shall keep another paper copy of the approved Plan and a posted copy of the permit prominently displayed at either the primary entrance of the job site or at another location that is observable to the public and inspectors until all construction is complete, all permanent sedimentation and erosion control measures are installed, and the site has been stabilized. After approving the Plan, if the County either upon review of such Plan or inspection of the job site, determines that the Plan is inadequate to meet the requirements of the Act and of this Ordinance, the County shall require a revised Plan. Pending the preparation of the 8-14 New Hanover County, NC | Unified Development Ordinance revised Plan, work shall cease or shall continue under conditions outlined by the appropriate authority. C.Erosion control Plans shall be disapproved unless accompanied by an authorized statement of financial responsibility and documentation of property ownership. This statement shall be signed by the person financially responsible for the land-disturbing activity or his or her attorney-in-fact. The statement shall include the mailing and street addresses of the principle place of business of the person financially responsible, and of the owner of the land, or registered agents. If the person financially responsible is not a resident of North Carolina, a North Carolina agent must be designated in the statement for the purpose of receiving notice of compliance or noncompliance with the Plan, the Act, this Ordinance, or rules or orders adopted or issued pursuant to this Ordinance. Except as provided in subsection D and K of this section, if the applicant is not the owner of the land to be disturbed, the draft erosion and sedimentation control Plan must include the owner’s notarized written consent for the applicant to submit a draft erosion and sedimentation control Plan and to conduct the anticipated land-disturbing activity. D.If the applicant is not the owner of the land to be disturbed and the anticipated land- disturbing activity involves the construction of utility lines for the provision of water, sewer, gas, telecommunications, or electrical service, the draft erosion and sedimentation control Plan may be submitted without the written consent of the owner of the land, so long as the owner of the land had been provided prior notice of the project. E.The New Hanover Soil and Water Conservation District and the County Planning Department within 20 days of receipt of any Plan, shall review such Plan and submit its comments and recommendations to the County Engineering Department. Failure of the Soil and Water Conservation District and the County Planning Department to submit its comments and recommendations within 20 days or within the prescribed additional time will not delay final action on the Plan. F.The County will review each complete Plan submitted to them and within 30 days of receipt. The person submitting the Plan, will be notified that it has been approved, approved with modifications, or disapproved. The County shall condition approval of an erosion control plan upon the applicant’s compliance with Federal and State Water Quality laws, regulations, and rules. The County shall also disapprove an erosion control plan if implementation of the Plan would result in a violation of rules adopted by the Environmental Management Commission to protect riparian buffers along surface waters. Failure to approve, approve with modifications, or disapprove a complete erosion and sedimentation control Plan within 30 days of receipt shall be deemed approval. Disapproval of an erosion control Plan or a revised erosion control Plan must specifically state in writing the reasons for disapproval. The County must approve, approve with modifications, or disapprove a revised Plan within 15 days of receipt, or it is deemed to be approved.
