B.

Rights of City The City and the Urban Forestry Committee (UFC), as an agent of the City, is authorized to plant, prune, maintain and remove any tree, plant, or shrub on City-owned or controlled land if it is determined necessary to ensure the public health and safety, to preserve and enhance the symmetry and beauty of public land, or to protect public improvements and utilities.

6.1.2. - Tree Maintenance and Protection

A.

Removal or Damage to Tree Without Prior Authorization

1.

General It is a violation of this Ordinance for a person to take any of the following actions to a tree on City-owned or controlled land without prior authorization from the UFC:

(a)

Remove, prune, or plant a tree;

(b)

Attach a rope, wire, nail, or sign to a tree;

(c)

Apply a liquid or solid substance to a tree that is harmful and could damage or destroy the tree; or

(d)

Deposit, place, store or maintain a stone, brick, sand, concrete or other impervious materials which may impede the free passage of water, air, or fertilizer to the roots of a tree.

2.

Tree Topping

(a)

It is a violation of this Ordinance for any person or City department (including a utility), to top a tree on City-owned or controlled land without a Public Tree Certificate in accordance with Section 2.5.12, Public Tree Certificate. For the purposes of this section, topping is defined as the severe pruning of tree limbs larger than 3 inches in diameter within the tree's crown to such a degree it removes the normal canopy of or disfigures the tree.

(b)

The topping of trees shall be approved only in cases where the tree is severely damaged by storm or other natural cause or where the UFC determines other pruning practices impractical (such as the pruning of trees directly under overhead utility lines).

B.

Removal of Damaged or Infested Trees The UFC may cause to be removed a tree or part of a tree that is in an unsafe condition, significantly damaged due to severe weather or other natural conditions, or is infested with disease, injurious fungus, insects, or other pests.

C.

Protection During Construction A tree on City-owned or controlled land shall be protected during any construction or excavation consistent with the City'sGuidelines and Standard Practices for Trees.

6.1.3. - Tree Planting, Pruning and Removal

A.

Public Tree Certificate Required Unless exempted in accordance with subsection (B) below, a person or City department seeking to plant, prune, or remove trees on City owned or controlled land shall receive approval of a public tree certificate in accordance with Section 2.5.12, Public Tree Certificate. In reviewing the application the UFC shall ensure that the intended activities meet the expectations of the urban forestry program and are consistent with the City's adopted Guidelines and Standard Practices for Trees.

B.

Exemptions The following development is exempt from the requirement to receive a public tree certificate, as long as the tree pruning and removal is consistent with the City's Guidelines and Standard Practices for Trees.

1.

Public and private utilities (water, sewer, electrical, gas, telecommunications, cable, etc.) in public rights-of-way, or in dedicated utility easements on land owned or controlled by the City.

2.

City departments that prune trees to maintain traffic visibility, pedestrian activity, and other similar public safety matters.

5.

New Development and Activities N.C. Administrative Code Section 15A NCAC 02B .0724(11) lists potential new development and activities within the buffer and categorizes them as deemed allowable, allowable upon authorization, or allowable with mitigation upon authorization. All development and activities not categorized as deemed allowable, allowable upon authorization, or allowable with mitigation upon authorization are considered allowable with exception and may not proceed within the surface water buffer, or outside the buffer if the development or activity would impact the buffer, unless a watershed variance is granted in accordance with Section 2.4.16, Variance. Watershed development plan approval, as provided for in Section 6.2.9 C.9, Watershed Plan Approval, is required for all new development and activity that is allowable. Such an approved plan shall constitute written authorization for uses that are allowable upon authorization or allowable with mitigation upon authorization and a statement to that effect shall be included on the approved plan. The requirements for each category are as follows:

(a)

Development Deemed Allowable Development and activities designated as deemed allowable are permissible without issuance of an authorization certificate by the TRC provided that they adhere to the limitations of the activity as defined in NC Administrative Code Section 15A NCAC 02B .0724(11). In addition, artificial streambank and shoreline stabilization is allowable in the Uwharrie (Lake Reece) and Lake Thom-A-Lex water supply watersheds, and in any non-water supply watershed. Deemed allowable development and activities shall be designed, constructed, and maintained to minimize vegetation and soil disturbance and to provide the maximum water quality protection practicable, including construction, monitoring and maintenance activities.

(b)

Development Allowable Upon Authorization Development and activities designated as allowable upon authorization may proceed provided that there are no practical alternatives to the requested development or activity and an authorization certificate is issued in accordance with Section 6.2.9 C.10, Authorization Certificates. This includes construction, monitoring, and maintenance activities. In addition, in the Uwharrie (Lake Reece) and Lake Thom-A-Lex water supply watersheds, and in any non-water supply watershed, publicly-funded linear projects such as roads, greenways, and sidewalks; water dependent structures such as docks; and minimal footprint uses such as poles, signs, utility appurtenances, and security lights are allowed provided there are no practical alternatives for locating them elsewhere, the built-upon area is minimized and channelization of stormwater runoff is avoided.

(c)

Development Allowable with Mitigation Upon Authorization Development and activities designated as allowable with mitigation upon authorization may proceed provided that there are no practical alternatives to the requested development or activity, an authorization certificate is issued in accordance with Section 6.2.9 C.10, Authorization Certificates, and an appropriate mitigation strategy is approved in accordance with Section 6.2.9 C.11, Mitigation.

D.

Slope and Buffer Protection

1.

Purpose The purpose of this provision is to limit the loss of soil, reduce soil erosion, minimize excess stormwater runoff, lessen the degradation of surface waters, and protect the buffers so established to protect surface waters. To this end, an addition to the surface water buffer requirements of Section 6.2.9 C, Surface Water Buffers, shall be required when intermittent and perennial surface waters abut moderate to steep slopes.

2.

Application

(a)

Such addition to the surface water buffer requirements shall only apply where that portion of the surface water is adjacent to moderate to steep slope areas.

(b)

For slopes with a value of 15 percent or less, no additional buffering is required.

(c)

For slopes of greater than 15 percent up to 25 percent, an additional 15-foot wide undisturbed buffer shall be required.

(d)

For slopes greater than 25 percent, an additional 30 feet of undisturbed buffer shall be required.

(e)

These calculations shall be made from each side of the surface water bank.

(f)

Such additional buffer required by this section shall extend Zone 2 of the surface water buffer.

(g)

In the case where Zone 3 is required, the extension of the Zone 2 surface water buffer may be offset by an identical decrease in width in Zone 3.

3.

Determination

(a)

The determination of whether such moderate to steep slope areas exist adjacent to a surface water shall be made by making 100 foot long perpendicular measurements at intervals, not greater than 50 feet in length, or at intervals as otherwise determined by the TRC, along the entire length of the surface water as measured from the top of bank.

(b)

These measurements shall be based on the most recent topographic survey of land that utilizes the smallest contour interval.

(c)

Applicants should consult the Development Guide for specific calculations, instructions, and illustrations.

E.

Additional Protection in Watershed Critical Areas Due to the proximity of watershed critical area (WCA)s to water supply reservoirs, fragile areas including steep slopes near perennial and intermittent streams, wetlands and drainage areas merit additional protection as prescribed in Section 3.8.12, Watershed Overlay (WSO) District.

6.2.10. - Low Impact Design

A.

Goals The primary goals of low impact design are to lower the impact of development on receiving waters, to encourage environmentally sensitive development, to help build communities based on environmental stewardship, and to reduce construction and maintenance costs of the stormwater infrastructure. The use of low impact design shall address these goals through the objectives found in subsection (B) below.

B.

Objectives

1.

Preserve Fragile Areas and Open Space Preserve fragile areas through the following:

(a)

Avoiding riparian areas, wetlands, steep slopes, high infiltration and hydric soils;

(b)

Maximizing open space and common area through cluster development where appropriate; and

(c)

Maintaining open space in a natural condition by reforestation where clearing has occurred.

2.

Minimize Land Disturbance and Built-Upon Area Design development to provide the following:

(a)

Efficient layout to reduce overall length of streets;

(b)

Shared parking and drives where possible to further reduce built-upon area;

(c)

Use of multiple stormwater control measures such as bio-retention cells and infiltration areas to minimize impact; and

(d)

Step floor elevations to fit terrain and avoid slab-on-grade construction to minimize land disturbance.

3.

Protect Water Resources Use site design techniques to replicate pre-existing hydrologic site conditions by placing water quality control devices close to the source. Techniques may include the following:

(a)

Designing driveways and parking areas with vegetated swales and/or sheet flow into infiltration areas; and

(b)

Using grass swales instead of curb and gutter to increase water filtration.

C.

Process The low impact design process is established in the City of High Point Stormwater Best Management Practices Design Manual.

The standards in this section shall apply to lands within an individual WSO district in addition to the standards in Section 6.2.11, General Standards and Restrictions.

A.

District Components Each WSO district is divided into 2 sub districts: the General Watershed Area (GWA), and the Watershed Critical Area (WCA).

1.

General Watershed Area (GWA) The General Watershed Area (GWA) component includes all land draining into a designated water supply reservoir within the City's jurisdiction, but outside the Watershed Critical Area (WCA) Overlay component. For the purposes of this section, the following constitute the designated water supply reservoirs:

(a)

Oak Hollow Lake;

(b)

City Lake;

(c)

Oakdale Reservoir (Jamestown);

(d)

Randleman Lake;

(e)

Uwharrie (Lake Reese); and

(f)

Lake Thom-A-Lex.

2.

Watershed Critical Area (WCA)

(a)

Location

(1)

The Watershed Critical Area (WCA) component covers the portion of the WSO subarea adjacent to a designated water supply intake or reservoir where risk associated with pollution is greater than from the remaining portions of the watershed.

(2)

The WCA component boundary extends either a minimum of 2,750 feet outward from the normal pool elevation of the reservoir in which the intake is located or to the ridgeline of designated water supply reservoir basins, whichever is closer to the normal pool elevation.

(3)

In the case of major streams feeding the water supply reservoir (i.e., East and West Forks of the Deep River and Hiatt Branch), the WCA subarea boundary extends to the nearest identifiable major feature which crosses the stream, and which is at least 2,750 feet upstream of the reservoir measured horizontally, except for the West Fork of the Deep River upstream from Oak Hollow Lake, where the major identifiable feature shall be defined as Sandy Ridge Road. The identifiable major feature may be a street, railroad, easement, or other means of travel, which can be used by emergency personnel to respond to spills.

(b)

Tiers Each WCA is comprised of 4 separate tiers, which are designated as follows:

(1)

Tier 1 Tier 1 consists of those lands within 200 feet measured horizontally from the pool elevation of the designated reservoir, which is 803 feet above mean sea level for Oak Hollow Lake, 756 feet above mean sea level for City Lake, 716 feet above mean sea level for Oakdale Reservoir, and 682 feet above mean sea level for Randleman Lake.

(2)

Tier 2 Tier 2 consists of those lands lying within an area bounded by Tier 1 and a line parallel to and 750 feet in distance from the normal pool elevation.

(3)

Tier 3 Tier 3 consists of those lands lying within an area bounded by Tier 2 and a line parallel to and 2,750 feet, measured horizontally from the normal pool elevation, or to the boundary of the WCA, whichever comes first, for all WCAs except the Randleman Lake WCA. Randleman Lake's WCA consists of those lands lying within an area bounded by Tier 2 and a line parallel to and 3,000 feet measured horizontally from the normal pool elevation, or to the boundary of the WCA, whichever comes first, except that Tier 3 along Richland Creek consists of those lands lying within an area bounded by Tier 2 and a line parallel to and 2,640 feet (1/2 mile) measured horizontally from the normal pool elevation or to the boundary of the WCA, whichever comes first.

(4)

Tier 4 Tier 4 consists of those lands lying in the area between the boundary of Tier 3 and the WCA boundary.

B.

District Boundaries The district boundaries for each WSO are shown on the City of High Point Watershed Map, which is incorporated herein by reference. WSO boundaries shall be determined in accordance with Section 3.1.5, Official Zoning Map, and Section 2.5.4, Determination.

2.

Dedication of these areas to the City as drainageway and open space may be required when authorized by Section 7.1.6 F, Drainage, or any other provision in this Ordinance.

3.

Where dedication is not required, a water quality conservation easement shall be recorded over wetlands and slopes greater than 15 percent.

4.

Where a water quality conservation easement serves to bring 2 or more lots into compliance with WCA requirements, the TRC may require that the wetlands and slopes covered by such easements be held as common area by an owners' association.

5.

The natural ground cover and natural tree canopy within a water quality conservation easement shall be preserved except when removal is authorized by the Public Services Department as part of the following:

(a)

Construction or maintenance of a public utility by the City or a designee;

(b)

Construction or maintenance of soil erosion and sedimentation control structures by the developer of the land, in accordance with Section 2.5.10, Land Disturbance Permit. After these structures are no longer needed, they shall be removed and the water quality conservation easement restored to a natural state;

(c)

Normal maintenance by mechanical means for the removal of dead, diseased, deformed, poisonous, or noxious vegetation and pests harmful to health; and

4.

Perennial and intermittent streams, lakes and ponds shall be protected as specified in Section 6.2.9 C, Surface Water Buffers.

G.

Density Shifting

1.

The location of development on soils and terrain most suited to protecting the water quality of water supply reservoirs is encouraged in the WCA by density shifting. The overall density of a development utilizing density shifting shall meet the applicable WCA density and stormwater control requirements, except as modified by this sub-section. Built-upon areas within such developments shall be designed and sited to minimize stormwater runoff impact to the receiving waters, and the remainder of the tract should remain in an undisturbed or natural state.

2.

Density shifting is utilized in developments having lot sizes in accordance with the minimum area permitted by the underlying zoning district or in approved conservation subdivisions. Through density shifting, developments may increase the maximum permitted residential densities otherwise established in this Ordinance if the development rights attached to acreage located within a tier are transferred within the same tract to an adjacent tier located farther from the water supply reservoir. Such transfer shall permit an additional number of dwelling units in the receiving tier. This addition is calculated by adding the density or dwelling units transferred from the adjacent tier to the density or dwelling units permitted in the receiving tier. The dwelling units permitted by acreage transfer from an adjacent tier shall be in addition to the number of dwelling units otherwise permitted in the receiving tier, but in no case shall the density allowed by the underlying zoning district be exceeded.

H.

Public Sanitary Sewer Required Except for development in the Randleman Lake WCA constructed under the low density option, all new development in a WCA shall be served by public sanitary sewer.

A soil erosion and sedimentation control plan may be disapproved pursuant to Section 6.3.3 H, Grounds for Plan Denial, if the plan fails to address the following control objectives:

A.

Identify Critical Areas On-site areas which are subject to severe erosion, and off-site areas which are especially vulnerable to damage from erosion and/or sedimentation, are to be identified and receive special attention;

B.

Limit Time of Exposure All land-disturbing activity is to be planned and conducted to limit exposure to the shortest feasible time;

C.

Limit Exposed Areas All land-disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time;

D.

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;

E.

Control Sedimentation All land-disturbing activity is to be planned and conducted so as to prevent off-site sedimentation damage; and

F.

Manage Stormwater Runoff When the increase in the velocity of stormwater runoff resulting from a land-disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans are to include measures to control the velocity at the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation of the stream.

6.3.5. - Mandatory Standards for Land-Disturbing Activity

Land-disturbing activity shall comply with the following requirements:

A.

Undisturbed Buffer Zone Required

1.

Land-disturbing activity shall not be permitted in proximity to a lake or natural watercourse unless an undisturbed buffer zone 25 feet wide is provided, or a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within the 25 percent of the buffer zone nearer the land-disturbing activity, provided that these standards 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.

Unless otherwise provided, the width of a buffer-zone is measured from the edge of the water to the nearest edge of the disturbed area, with the 25 percent of the strip nearer the land-disturbing activity containing natural or artificial means of confining visible siltation.

3.

Waters that have been classified as trout waters by the North Carolina Environmental Management Commission shall have an undisturbed buffer zone 25 feet wide, or of sufficient width to confine visible siltation within the 25 percent of the buffer zone nearest the land-disturbing activity, whichever is greater. Provided, however, that the Engineering services Director may approve plans which include land-disturbing activity along trout waters when the duration of the disturbance is temporary and the extent of the disturbance is minimal.

4.

The 25 foot minimum width factor for an undisturbed buffer zone adjacent to designated trout waters shall be measured horizontally from the top of the bank.

5.

Where a temporary and minimal disturbance is permitted, land-disturbing activities in the buffer zone adjacent to designated trout waters shall be limited to a maximum of 10 percent of the total length of the buffer zone within the tract so that there is not more than 100 linear feet of disturbance in each 1000 linear feet of buffer zone. Larger areas may be disturbed with the written approval of DENR.

6.

Land-disturbing activity shall not be undertaken within a buffer zone adjacent to designated trout waters that will cause adverse temperature fluctuations in these waters, as established in 15 NCAC 2B.0211 "Fresh Surface Water Classification and Standards".

B.

Fill Material Unless a permit from the Public Services Director 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 12 inches, and any materials which would cause the site to be regulated as a landfill by the State of North Carolina.

C.

Graded Slopes and Fills

1.

The angle for graded slopes and fills shall be no greater than a 2-to-1 slope (horizontal to vertical) if they are to be stabilized with vegetative cover.

2.

Slopes or fills steeper than 2-to-1 must be protected by structures.

3.

In any event, slopes left exposed will, 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.

D.

Ground Cover Whenever land-disturbing activity is undertaken on a tract, the person conducting the land-disturbing activity shall install such sedimentation and erosion control devices and practices as 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 6.3.6 B, High Quality Water Zones, of this Ordinance, provisions for permanent ground cover sufficient to restrain erosion must be accomplished within 90 calendar days following completion of construction or development.

(Ord. No. 7984/24-01, § 2(Pt. A), 1-16-2024)

6.3.6. - Design and Performance Standards

A.

Design for 10-Year Storm Except as provided in Section 6.3.6 B, High Quality Water Zones, erosion and sedimentation control measures, structures, and devices shall be so planned, designed, and constructed to provide protection from the calculated maximum peak rate of runoff from the 10-year storm. Runoff rates shall be calculated using the procedures in the USDA, Soil Conservation Service's "National Engineering Field Manual for Conservation Practices," or other acceptable calculation procedures.

B.

High Quality Water Zones 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 within the boundaries of the tract of 20 acres. 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 DENR.

2.

Soil erosion and sedimentation control measures, structures, and devices within HQW zones shall be planned, designed, and constructed to provide protection from the runoff of the 25-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture Soil Conservation Service's "National Engineering Field Manual for Conservation Practices" or according to procedures adopted by any other agency of this State or the United States or any generally recognized organization or association.

3.

Sediment basins within HQW zones shall be designed and constructed so the basin will have a settling efficiency of at least 70 percent for the 40 micron (0.04 mm) size soil particle transported into the basin by the runoff of that 2-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture Soil Conservation Service's "National Engineering Field Manual for Conservation Practices" or according to procedures adopted by any other agency of this State or the United States or any generally recognized organization or association.

4.

Newly constructed open channels in HQW zones shall be designed and constructed with side slopes no steeper than 2 horizontal to 1 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 acceptable ditch liners. In any event, the angle for side slopes shall be sufficient to restrain accelerated erosion.

5.

Ground cover sufficient to restrain erosion must be provided for any portion of a land-disturbing activity in a HQW zone within 7 days of completion of any phase of grading.

C.

Sedimentation Basins Except as provided for in Section 6.3.6 B, High Quality Water Zones, above, all sedimentation basins shall be designed and constructed to have a settling efficiency of at least 70 percent for the 40 micron (0.04 mm) size soil particle.

6.3.7. - 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 Standard

1.

Land-disturbing activity shall be conducted so that the post-construction velocity of the 10-year storm runoff in the receiving natural watercourse to the discharge point does not exceed the greater of:

(a)

The velocity established in Table 6.3.7.B, Maximum Permissible Velocity for Stormwater Discharges; or

(b)

The velocity of the 10-year storm runoff in the receiving natural watercourse prior to development.

2.

If condition B.1 above cannot be met, the receiving watercourse (and discharge point) shall be designed and constructed to withstand the expected velocity anywhere the velocity exceeds the "prior to development" velocity by 10 percent.

NOTES:
[1] These standards are 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

 

C.

Acceptable Management Measures

1.

General Measures applied alone or in combination to satisfy the intent of this section are acceptable if there are no objectionable secondary consequences. The N.C. Sedimentation Commission and the City recognize that the management of stormwater 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.

2.

Stormwater Runoff Management Alternatives Some alternatives are to:

(a)

Avoid increases to surface runoff volume and velocity by including measures to promote infiltration to compensate for increased runoff from areas rendered impervious;

(b)

Avoid increases in stormwater discharge velocities by using detention devices, vegetated or roughened swales, and waterways in-lieu of closed drains and high velocity paved sections;

(c)

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;

(d)

Protect watercourses subject to accelerated erosion by improving cross sections and/or providing erosion-resistant lining; or

(e)

Upgrade or replace the receiving device structure, or watercourse 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 that stormwater discharge velocities will not create an erosion problem in the receiving watercourse.

(Ord. No. 7365/17-108, § 1, 11-20-2017)

6.3.8. - 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, and waste areas for surplus materials other than landfills regulated by the Public Service Department, shall be considered as part of the land-disturbing activity where the borrow material is being used or from which the waste material originated. When the person conducting 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.

6.3.9. - Access and Haul Roads

Temporary access and haul roads, other than existing public roads, constructed or used in connection with any land-disturbing activity shall be considered a part of such activity.

6.3.10. - Operations in Lakes or Natural Watercourses

A.

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 disturbance of the stream channel.

B.

The relocation of a stream, where relocation is an essential part of the proposed activity, shall be planned and executed so as to minimize changes in the stream flow characteristics, except when justification for significant alteration to flow characteristic is provided.

C.

The U.S. Army Corps of Engineers shall be notified by the developer of any planned operation in lakes or natural watercourses for possible issuance of Section 404 or other permits.

6.3.11. - Responsibility for Maintenance

During the development of a site, the person conducting the land-disturbing activity shall install and maintain all temporary and permanent soil erosion and sedimentation control measures as required by the approved plan, by any provision of this Ordinance, the Act, or by any order adopted pursuant to this Ordinance or the North Carolina Sedimentation Pollution Control Act of 1973 (see Section 113A-50 of the North Carolina General Statutes). After site development, the landowner or person in possession or control of the land shall install and/or maintain all necessary permanent soil erosion and sedimentation control measures, except those measures installed within a road or street right-of way or easement accepted for maintenance by a governmental agency.

6.3.12. - Additional Measures

Whenever the Engineering Services Director determines that significant sedimentation is occurring as a result of land-disturbing activity, despite application and maintenance of protective practices, the person conducting the land-distributing activity will be required to and shall take additional protective action.

6.3.13. - Existing Uncovered Areas

A.

Applicability All uncovered areas existing on the effective date of this Ordinance which are the result of land-disturbing activity, which exceed 1 acre, which are subject to continued accelerated erosion, and which are causing off-site damage from sedimentation, shall be provided with a ground cover or other protective measures, structures, or devices sufficient to restrain accelerated erosion and control off-site sedimentation.

B.

Notice of Violation The Engineering Services Director will serve upon the landowner or other person in possession or control of the land, a written notice of violation in accordance with Section 9.6.1, Notice of Violation. In determining the corrective measures required and the time allowed for compliance, the Engineering Services Director shall take into consideration the economic feasibility, technology, and quantity of work required and shall set reasonable attainable time limits for compliance.

C.

Requiring Erosion Control Plan The Engineering Services Director reserves the right to require preparation and approval of a soil erosion and sedimentation control plan in any instance where extensive control measures are required.

D.

Exemption This rule shall not require ground cover on cleared land forming the future basin of a planned reservoir.

(Ord. No. 7287/17-29, § 14, 4-3-2017)

6.3.14. - Restoration after Non-Compliance

The Engineering Services Director may require a person who engaged in a land-disturbing activity and failed to retain sediment generated by the activity, as required by North Carolina General Statutes Section 113A-57 (3), to restore the waters and land affected by the failure 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.

Elevated Buildings Fully enclosed areas associated with new construction and substantially improved structures that are below the lowest floor shall comply with the following:

(a)

Not be designed or used for human habitation, but only be used for parking of vehicles, building access, or limited storage of maintenance equipment used in connection with the premises. Access to the enclosed area shall be the minimum necessary to allow for parking of vehicles (garage door) or limited storage of maintenance equipment (standard exterior door), or entry to the living area (stairway or elevator). The interior portion of such enclosed area shall not be finished or partitioned into separate rooms, except to enclose storage areas.

(b)

Be constructed entirely of flood resistant materials at least to the regulatory flood protection elevation.

(c)

Include, in Zones A, AO, AE, and A1-30, flood openings to automatically equalize hydrostatic flood forces on walls by allowing for the entry and exit of floodwaters. To meet this requirement, the openings shall be certified by a professional engineer or architect or meet or exceed the following minimum design criteria:

(1)

A minimum of 2 flood openings on different sides of each enclosed area subject to flooding;

(2)

The total net area of all flood openings shall be at least 1 square inch for each square foot of enclosed area subject to flooding;

(3)

If a building has more than 1 enclosed area, each enclosed area shall have flood openings to allow floodwaters to automatically enter and exit;

(4)

The bottom of all required flood openings shall be no higher than 1 foot above the adjacent grade;

(5)

Flood openings may be equipped with screens, louvers, or other coverings or devices, provided they permit the automatic flow of floodwaters in both directions; and

(6)

Enclosures made of flexible skirting are not considered enclosures for regulatory purposes, and, therefore, do not require flood openings. Masonry or wood underpinning, regardless of structural status, is considered an enclosure and requires flood openings as outlined above.

4.

Additions/Improvements

(a)

Not a Substantial Improvement

(1)

In cases where an addition or improvement to a pre-FIRM structure does not constitute a substantial improvement, the addition or improvement shall be designed to minimize flood damages and shall not render the pre-FIRM structure any more nonconforming with respect to the standards in this section.

(2)

In cases where an addition and/or improvement to a post-FIRM structure does not constitute a substantial improvement to the existing structure, then only the additions or improvements shall comply with the standards for new construction.

(3)

Additions to post-FIRM structures with no modifications to the existing structure other than a standard door in a common wall shall require only the addition to comply with the standards for new construction.

(b)

Substantial Improvements In cases where an addition or improvement to a pre- or post-FIRM structure (whether in combination with interior modifications or not) do constitute a substantial improvement, both the existing structure and the addition and/or improvements shall comply with the standards for new construction.

5.

Recreational Vehicles Recreational vehicles shall either:

(a)

Be on site for fewer than 180 consecutive days and be fully licensed and ready for highway use (a recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities, and has no permanently attached additions); or

(b)

Meet all the requirements for new construction.

6.

Temporary Non-Residential Structures Temporary nonresidential structures shall not remain within the special flood hazard area for a time period exceeding 3 months. This time period may be renewed up to a maximum of 1 year.

7.

Accessory Structures

(a)

An accessory structure shall comply with the following:

(1)

Not be used for human habitation (including working, sleeping, living, cooking or restroom areas);

(2)

Not be temperature-controlled;

(3)

Be designed to have low flood damage potential;

(4)

Be constructed and placed on the building site so as to offer the minimum resistance to the flow of floodwaters;

(5)

Be firmly anchored; and

(6)

Incorporate flood openings to facilitate automatic equalization of hydrostatic flood forces below regulatory flood protection elevation, if necessary.

(b)

An accessory structure with a footprint less than 150 square feet that satisfies the criteria outlined above does not require an elevation or floodproofing certificate.

(c)

Elevation or floodproofing certifications are required for all other accessory structures in accordance with Section 6.4.2 B, Certification Requirements.

C.

Standards for Floodplains without Established Base Flood Elevations In addition to the standards in Section 6.4.3 A, General Standards, and Section 6.4.3 B, Specific Standards, development within the special flood hazard areas designated as Approximate Zone A and established in Section 6.4.1 B, Basis for Establishing Special Flood Hazard Areas, where no BFE is provided by FEMA, shall be subject to the following:

1.

No encroachments, including fill, new construction, substantial improvements or new development shall be allowed within a distance of 20 feet each side from top of bank or 5 times the width of the stream, whichever is greater, unless certification with supporting technical data by a registered professional engineer is provided demonstrating that such encroachments will not result in any increase in flood levels during the occurrence of the base flood discharge; and

2.

The BFE used in determining the regulatory flood protection elevation shall be determined based on the following criteria:

(a)

When BFE data is available from other sources, all new construction and substantial improvements within such areas shall also comply with all applicable provisions of this section and the Ordinance and shall be elevated or floodproofed.

(b)

All subdivision, manufactured home park, and other development proposals shall provide BFE data if development is greater than 5 acres or has more than 50 lots/manufactured home sites. The BFE data shall be adopted by reference in accordance with Section 6.4.1 B, Basis for Establishing Special Flood Hazard Areas, and utilized in implementing this section.

(c)

When BFE data is not available from a Federal, State, or other source as outlined above, the reference level shall be elevated to or above the regulatory flood protection elevation.

D.

Standards for Riverine Floodplains with BFE, but Without Established Floodways or Non-Encroachment Areas In addition to the standards in Section 6.4.3 A, General Standards, and Section 6.4.3 B, Specific Standards, development along rivers and streams where BFE data is provided by FEMA or is available from another source but neither floodway nor non-encroachment areas are identified for a special flood hazard area on the FIRM or in the FIS report, shall be subject to the following:

1.

Until a regulatory floodway or non-encroachment area is designated, no encroachments, including fill, new construction, substantial improvements, or other development, shall be permitted unless certification with supporting technical data by a registered professional engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than 1 foot at any point within the community.

E.

Floodways and Non-Encroachment Areas In addition to the standards in Section 6.4.3 A, General Standards, and Section 6.4.3 B, Specific Standards, development proposed in floodways or non-encroachment areas established by Section 6.4.1 B, Basis for Establishing Special Flood Hazard Areas, shall be subject to the following:

1.

No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted unless:

(a)

It is demonstrated that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood, based on hydrologic and hydraulic analyses performed in accordance with standard engineering practice and presented to the Engineering Services Director prior to issuance of floodplain development permit; or

(b)

A conditional letter of map revision (CLOMR) is approved by FEMA.

(c)

A letter of map revision (LOMR) must also be obtained upon completion of the proposed encroachment.

2.

If (E.1) above is satisfied, development shall comply with all applicable flood hazard reduction provisions of this section.

3.

No manufactured dwellings shall be permitted, except replacement manufactured dwellings in an existing manufactured dwelling park or subdivision, provided the following provisions are met:

(a)

The anchoring and the elevation standards of Section 6.4.3 B.2, Manufactured Dwellings; and

(b)

The no encroachment standard of (1) above.

F.

Standards for Areas of Shallow Flooding (Zone AO) In addition to the standards in Section 6.4.3 A, General Standards, and Section 6.4.3 B, Specific Standards, development located within the Special Flood Hazard Areas established in Section 6.4.1 B, Basis for Establishing Special Flood Hazard Areas, as shallow flooding areas shall comply with the following:

1.

The reference level shall be elevated at least as high as the depth number specified on the Flood Insurance Rate Map (FIRM), in feet, plus a freeboard of 2 feet, above the highest adjacent grade; or at least 2 feet above the highest adjacent grade if no depth number is specified;

2.

Nonresidential structures may, in-lieu of elevation, be floodproofed to the same level as required by subsection F.1 above so that the structure, together with attendant utility and sanitary facilities below that level shall be watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.

3.

Certification is required in accordance with Section 6.4.2 B, Certification Requirements; and

4.

Adequate drainage paths shall be provided around structures on slopes, to guide floodwaters around and away from proposed structures.
