§ 180-16K(2)

Accessory structures shall have no kitchen facilities and shall not be used for living quarters nor used for dwelling purposes or occupied overnight.

In the Agricultural District there shall be a limit of two structures allowed within the special flood hazard area, inclusive of agricultural exempt structures as determined by the County and shall not exceed the cumulative area of 320 square feet for both structures.

In the Agricultural District there shall be a limit of two structures allowed within the special flood hazard area, inclusive of agricultural exempt structures as determined by the County and shall not exceed the cumulative area of 320 square feet for both structures.

In residential districts there shall be a limit of one structure allowed within the special flood hazard area and the structure is to be used for storage of property maintenance, recreation equipment, or a pavilion and shall be composed of materials approved by the Planning Department.

It shall be no larger than 200 square feet and shall meet the requirements for flood venting based on square footage of the structure and for anchoring.

Development within the special flood hazard areas shall not adversely impact any threatened and endangered special status faunal species as identified by the Virginia Department of Wildlife Resources (DWR).

Any alteration, repair, reconstruction or improvements to a building that is in compliance with the provisions of this section shall meet the requirements of new construction as contained in this section.

New construction and substantial improvements shall be built according to this section and the VA USBC, and anchored to prevent flotation, collapse or lateral movement of the structure.

The building of critical facilities in the special flood hazard area 1% annual chance and 0.2% annual chance flood/shaded zone X area shall be prohibited.

New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.

In any flood zone the Floodplain Administrator may require a hydrologic and hydraulic analysis for any development.

Manufactured homes shall be anchored to prevent flotation, collapse or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors.

New construction or substantial improvements shall be constructed by methods and practices that minimize flood damage.

Any alteration, repair, reconstruction or improvements to a building that is not in compliance with the provisions of this section shall be undertaken only if said nonconformity is not furthered, extended or replaced.

Substantial improvement of any existing commercial, industrial, or institutional buildings located in all A and AE Zones shall have the lowest floor, including basement, elevated to no lower than 2 1/2 feet (30" above BFE) above the base flood elevation.

These buildings may be floodproofed in lieu of being elevated, provided that all areas of the building components below the elevation corresponding to the BFE plus 2 1/2 feet (30" above BFE) are watertight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy.

Within the Special Flood Hazard Areas Zones A and AE, new construction or substantial improvement of any residential structure (including manufactured homes) shall have the lowest floor, including basement, elevated no lower than 2 1/2 feet (30" above BFE) above the base flood elevation.

New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters.

Electrical, heating, ventilation, plumbing, air-conditioning equipment and other service facilities, including duct work, shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding.

New and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system.

Enclosed areas of new construction or substantially improved structures which are below the regulatory flood protection elevation shall not be designed or used for human habitation, but shall only be used for parking of vehicles, building access or limited storage of maintenance equipment.

Prior to installation, any fence located within the special flood hazard area shall first receive a zoning permit, floodplain determination and documentation identifying the fence type and its location to be approved by the Floodplain Administrator or Zoning Administrator.

The flood-carrying capacity within an altered or relocated portion of any watercourse shall be maintained. Under no circumstances shall any use, activity, and/or development adversely affect the capacity of the channels or floodways of any watercourse, drainage ditch, or any other drainage facility or system.

Be constructed entirely of flood-resistant materials below the regulatory flood protection elevation.

Provide a minimum of two openings on different sides of each enclosed area subject to flooding. The total net area of all openings must be at least one square inch for each square foot of enclosed area subject to flooding. The bottom of all required openings shall be no higher than one foot above the adjacent grade.

The parking and storage of inoperative major recreational equipment shall be prohibited.

All manufactured homes placed or substantially improved in an existing manufactured home park or subdivision must be elevated so that the lowest floor of the manufactured home is elevated no lower than one foot 2 1/2 feet (30" above BFE) above the base flood elevation.

The manufactured home chassis is supported by reinforced piers or other foundation elements of at least an equivalent strength and of no less than 36 inches in height above the grade.

All recreational vehicles placed on sites must either be on the site for fewer than 180 consecutive calendar days in any one year and be fully licensed and ready for highway use.

Solid panel or board on board/batten fencing shall not be permitted.

All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards.

All subdivision proposals shall be consistent with the need to minimize flood damage.

Hydrologic and hydraulic analysis and/or drainage study, erosion and sediment, encroachment analysis and base flood elevation data shall be provided for subdivision proposals and other proposed development proposals (including manufactured home parks and subdivisions greater than 50 lots or five acres) that are in the SFHA or within 100 feet of the boundary of the special flood hazard area.

All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage.

Prior to any proposed alteration or relocation of any channels or of any watercourse, stream, etc., within this jurisdiction a permit shall be obtained from the United States Corps of Engineers (USACE), the Virginia Department of Environmental Quality (DEQ) and the Virginia Marine Resources Commission (VMRC).

They must also meet a linear setback of 50 feet from the edge of the regulatory floodway as determined in the Flood Insurance Study or through a base floodwater surface elevation and contour analysis survey.
