OVERLAY ZONING DISTRICTS
(A)
Overlay Zoning Districts Establishment and Purpose. This article establishes overlay districts, which apply additional standards to the development and design requirements of land in the County. These district standards exist as overlays to the existing underlying zoning districts, and, as such, the provisions for the overlay districts do not replace, but shall serve to supplement the underlying district provisions. King George County is hereby divided into the following overlay zoning districts:
Table V-1. Overlay Zoning Districts
(A)
Chesapeake Bay Preservation Area Overlay (CBPA).
(1)
Findings of Fact. The Chesapeake Bay, along with its tributaries, is one of the most important and productive estuarine systems in the world, providing economic and social benefits to the citizens of King George County and the Commonwealth of Virginia. The health of the Bay is vital to maintaining King George County's economy and the welfare of its citizens.
(2)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including non-point source pollution from land uses and development. Existing high-quality waters are worthy of protection from degradation to guard against further pollution. Certain lands that are proximate to shorelines have intrinsic water quality value due to the ecological and biological processes they perform. Other lands have severe development constraints from flooding, erosion, and soil limitations. With proper management, they offer significant ecological benefits by providing water quality maintenance and pollution control, as well as flood and shoreline erosion control. These lands together, designated by the Board of Supervisors as Chesapeake Bay Preservation Areas (hereinafter "CBPAs"), need to be protected from destruction and damage to protect the quality of water in the Bay and consequently the quality of life in King George County and the Commonwealth of Virginia.
(3)
Applicability. All land within King George County is designated as a Chesapeake Bay Preservation Area (CBPA) and is either classified as a Resource Protection Areas (RPA) or a Resource Management Area (RMA). Adherence to the CBPA regulations provided in this Division is required for all lots and parcels within King George County.
(4)
Purpose. This ordinance is enacted to implement the requirements of §62.1-44.15:67, et seq. of the Code of Virginia (The Chesapeake Bay Preservation Act). The purpose of the Chesapeake Bay Preservation Overlay is to:
(i)
Protect existing high-quality state waters;
(ii)
Restore all other state waters to a condition or quality that will permit all reasonable public uses and will support the propagation and growth of all aquatic life, including game fish, which might reasonably be expected to inhabit them;
(iii)
Safeguard the clean waters of the Commonwealth from pollution;
(iv)
Prevent any increase in pollution;
(v)
Reduce existing pollution; and
(vi)
Promote water resource conservation to provide for the health, safety, and welfare of the present and future citizens of King George County.
(5)
Unless otherwise stated in this Article, the review and approval procedures provided for in Article 3 of this Ordinance and Chapters 4 (Building and Building Regulations), Chapter 6 (Erosion and Settlement Control), and Chapter 5.5 (Wetlands and Stormwater Ordinances) of the County Code shall be followed in reviewing and approving development, redevelopment, and uses governed by these Chesapeake Bay Preservation Overlay regulations.

(1)
Purpose. The purpose of the floodplain management overlay provisions are to prevent:
(i)
The loss of life and property;
(ii)
The creation of health and safety hazards;
(iii)
The disruption of commerce and governmental services;
(iv)
The extraordinary and unnecessary expenditure of public funds for flood protection and relief; and
(v)
The impairment of the tax base by:
1.
Requiring all those uses, activities, and developments that do occur in flood-prone areas to be protected and/or flood-proofed against flooding and flood damage;
2.
Regulating uses, activities, and development which, alone or in combination with other existing or future uses, activities, and development, will cause unacceptable increases in flood heights, velocities, and frequencies;
3.
Restricting or prohibiting certain uses, activities, and development from locating within areas subject to flooding; and
4.
Protecting individuals from buying land and structures, which are unsuited for intended purposes because of flood hazards.
(C)
Highway Corridor Overlay (HCOD).
(1)
Purpose. The purpose of the HCOD is to:
(i)
Maintain the long-term safety and mobility function of Route 3 and Route 301;
(ii)
Limit the number of conflict points, thereby reducing the need for additional crossover locations and traffic signals;
(iii)
Promote improved pedestrian and vehicular circulation;
(iv)
Encourage land assembly and the most desirable use of land in accordance with the King George County Comprehensive Plan;
(v)
Encourage designs which produce a desirable relationship between individual buildings, the circulation systems and adjacent areas;
(vi)
Control signage, visibility obstructions and clutter; and
(vii)
Permit a flexible response of development to market factors as well as to provide incentives for development of a variety of land uses and activities of high quality.
(D)
Military Compatibility Area Overlay District (MCAOD).
(1)
Purpose. The purpose of Military Compatibility Area Overlay District (MCAOD) is to:
(i)
Recognize the existence of Naval Support Facility Dahlgren (NSF) and address the interaction between NSF Dahlgren and surrounding land uses;
(ii)
Support NSF Dahlgren as a valuable economic development asset in the community;
(iii)
Protect public's health, safety, welfare, quality of life, and the economic stability of the County;
(iv)
Ensure that prospective buyers and developers of real estate in the vicinity of NSF Dahlgren are aware of the presence of the facility, their operations, and the potential impacts that they may have;
(v)
Protect the integrity of the operations and continued existence of NSF Dahlgren by establishing and delineating a geographic area which is subject to compatibility requirements caused by activities related to the normal operations of such facilities; and
(vi)
Promote an orderly transition between community and military land uses so that land uses remain compatible.
(A)
The Chesapeake Bay Preservation Area Overlay (CBPA) shall apply to all lands identified as Chesapeake Bay Preservation Areas (CBPAs) as designated by the Board of Supervisors and as shown on the Chesapeake Bay Map. The Chesapeake Bay Map, together with all explanatory matter thereon, is hereby adopted by reference and declared to be a part of this Article. The Chesapeake Bay Map shows the general location of CBPAs and should be consulted by persons contemplating activities within King George County prior to engaging in a regulated activity.
(B)
All area within the County (CPBA) is either designated as a Resource Protection Area (RPA) or as a Resource Management Area (RMA). Components of the CBPA include the following:
(1)
The Resource Protection Area (RPA), including:
(i)
Tidal wetlands;
(ii)
Nontidal wetlands connected by surface flow and contiguous to tidal wetlands or water bodies with perennial flow;
(iii)
Tidal shores; and
(iv)
A 100-foot vegetated buffer area located adjacent to and landward of the components listed in subsections i through iii, above, and along both sides of any water bodies with perennial flow.
(2)
The Resource Management Area (RMA), including:
(i)
The remaining area of the County that is not identified as being within the RPA.
(C)
Portions of RPAs and RMAs designated by the Board of Supervisors as Intensely Developed Areas (IDA) shall serve as redevelopment areas. Areas so designated shall comply with all erosion and sediment control requirements and the performance standards for redevelopment in Section 5-2-6, Performance Standards.
(A)
Interpretation of Resource Protection Area (RPA) Boundaries shall be made as follows:
(1)
Delineation by the Applicant. The site-specific boundaries of the RPA shall be determined by the applicant through the performance of an environmental site assessment as part of the Plan of Development Process or Water Quality Impact Assessment (WQIA), subject to approval by the Administrator and in accordance with Section 5-2-8, Plan of Development, and Section 5-2-7, Water Quality Impact Assessment, of this Article. The CBPA Overlay Map shall be used as a guide to the general location of RPAs; however, this does not relieve the applicant of the requirement that they perform site-specific determination of the RPA.
(2)
Delineation by the Zoning Administrator. The Administrator may waive the requirement for an environmental site assessment and perform the delineation, when requested by an applicant wishing to construct a single-family dwelling. The Administrator may use hydrology, soils, plant species, and other data, and consult other appropriate resources as needed to perform the delineation.
(3)
Delineation Confirmation or Conflict. Where the applicant has provided a site-specific delineation of the RPA, the Administrator will verify the accuracy of the boundary delineation. In determining the site-specific RPA boundary, the Administrator may render adjustments to the applicant's boundary delineation, in accordance with Section 5-2-8, Plan of Development. In the event the adjusted boundary delineation is contested by the applicant, the applicant may seek relief, in accordance with the provisions of Section 5-2-10, Denial/Appeal of Plan.
In any case where the requirements of this Article conflict with any other provision of the King George County Code or existing state or federal regulations, whichever imposes the more stringent restrictions shall apply.
Permitted uses, Special Exception uses, accessory uses, and special requirements shall be as established by the underlying zoning district, unless specifically modified by the requirements set forth herein.
Lot size shall be subject to the requirements of the underlying zoning district(s), provided that any lot shall have sufficient area outside the RPA to accommodate an intended development, in accordance with the performance standards in Section 5-2-6, when such development is not otherwise allowed in the RPA.
(A)
Purpose and Intent. The performance standards establish the means to minimize erosion and sedimentation potential, reduce land application of nutrients and toxins, and maximize rainwater infiltration. Natural ground cover, especially woody vegetation, is most effective in holding soil in place and preventing site erosion. Indigenous vegetation, with its adaptability to local conditions without the use of harmful fertilizers or pesticides, filters stormwater runoff. Minimizing impervious cover enhances rainwater infiltration and effectively reduces stormwater runoff potential. The purpose and intent of these requirements are also to implement the following objectives:
(1)
Prevent a net increase in non-point source pollution from new development;
(2)
Achieve a 10% reduction in non-point source pollution from redevelopment; and
(3)
Achieve a 40% reduction in non-point source pollution from agricultural uses.
(B)
Required Conditions.
(1)
All development and redevelopment equal to or greater than 2,500 square feet of land disturbance shall be subject to a plan of development process, including the approval of a site plan or a subdivision plat in accordance with the provisions of the Zoning and Subdivision Ordinance unless otherwise provided for.
(2)
Development in RPAs may be allowed only if it: (i) is water-dependent; or (ii) constitutes redevelopment meeting the criteria provided below:
(i)
A new or expanded water-dependent facility may be allowed provided that the following criteria are met:
1.
It does not conflict with the Comprehensive Plan;
2.
It complies with the performance criteria set forth in Section 5-2-6 of this Article;
3.
Any non-water-dependent component is located outside of the RPA; and
4.
Access to the water-dependent facility will be provided with the minimum disturbance necessary. Where practicable, a single point of access will be provided.
(ii)
Redevelopment on isolated redevelopment sites outside of an area designated by King George County to be an IDA shall be permitted only if there is no increase in the amount of impervious cover and no further encroachment within the RPA and shall conform to the stormwater management criteria set forth in the Erosion and Sediment Control Law and the Virginia Stormwater Management Act and their attendant regulations, as well as all applicable stormwater management requirements of other state and federal agencies.
(iii)
Roads and Driveways not exempt under subdivision B 1 of 9VAC25-830-150 and which, therefore, must comply with the provisions of the following:
1.
The Administrator makes a finding that there are no reasonable alternatives to aligning the road or driveway in or across the RPA;
2.
The alignment and design of the road or driveway are optimized, consistent with other applicable requirements, to minimize (i) encroachment of the RPA and (ii) adverse effects of on water quality;
3.
The design and construction of the road or driveway satisfy all applicable criteria of this Ordinance, including submission of a water quality impact assessment; and
4.
The Administrator reviews the plan for the road or driveway proposed in or across the RPA in coordination with other local government, state, federal requirements, and development approvals.
5.
The plan for the road or driveway proposed in or across the RPA shall be coordinated with either a Site Plan in accordance with Article III, Permits and Applications, of this Ordinance, or a subdivision submittal in accordance with Article X, Subdivision, of this Ordinance.
(iv)
Flood control and stormwater management facilities that drain or treat water from multiple development projects, or from a significant portion of a watershed, may be allowed in an RPA provided such facilities are allowed and constructed in accordance with the Virginia Stormwater Management Act and its attendant regulations, and provided that:
1.
The local government has conclusively established that location of the facility within the RPA is the optimum location;
2.
The size of the facility is the minimum necessary to provide necessary flood control or stormwater treatment, or both;
3.
The facility must be consistent with a comprehensive stormwater management plan developed and approved in accordance with Chapter 5.5, Environment, of the King George County Code;
4.
All applicable permits for construction in state or federal waters must be obtained from the appropriate state and federal agencies, such as the U.S. Army Corps of Engineers, the department, and the Virginia Marine Resources Commission;
5.
Approval must be received from the local government prior to construction; and
6.
Routine maintenance is allowed to be performed on such facilities to assure that they continue to function as designed. It is not the intent of this subdivision to allow a best management practice that collects and treats runoff from only an individual lot or some portion of the lot to be located within an RPA.
(3)
A Water Quality Impact Assessment (WQIA) shall be required for any proposed use, land disturbance, development, or redevelopment within RPAs and for any development within RMAs when required by the Administrator, as provided in Section 5-2-7 of this Article.
(C)
General Performance Standards for Development or Redevelopment.
(1)
Land disturbance shall be limited to the area necessary to provide for the proposed use or development.
(i)
In accordance with an approved site plan, the limits of land disturbance, including clearing or grading shall be strictly defined by the construction footprint. These limits shall be clearly shown on submitted plans and physically marked on the development site.
(ii)

(iii)
Diseased trees or trees weakened by age, storm, or other injury may be removed, when approved by the Administrator. Other woody vegetation on site shall also be preserved outside the approved construction footprint.
(iv)
Prior to clearing or grading, suitable protective barriers, such as safety fencing, shall be erected 5 ft. outside of the dripline of any tree or stand of trees to be preserved. These protective barriers shall remain so erected throughout all phases of construction.
(v)
The storage of equipment, materials, debris, or fill shall not be allowed within the area protected by the barrier.
(3)
Land development shall minimize impervious cover to promote infiltration of stormwater into the ground consistent with the proposed use or development.
(i)
Grid and modular pavements may be used for any required alley, or other low traffic driveway, unless otherwise approved by the Administrator.
(ii)
Parking areas and driveways shall be designed to minimize impervious surfaces.
(4)
Notwithstanding any other provisions of this Article and Chapter 6, Erosion and Sediment Control, of the King George County Code or exceptions or exemptions thereto, any land disturbing activity equal to or greater than 2,500 square feet, including construction of all single-family houses, septic tanks, and drainfields, shall comply with the requirements of Chapter 6, Erosion and Sediment Control, of the King George County Code.
(5)
All on-site sewage disposal systems not requiring a Virginia Pollutant Discharge Elimination System (VPDES) permit shall:
(i)
Have installed one of the three maintenance provisions:
1.
An inspection port;
2.
An effluent filter; or
3.
A reduced maintenance baffled tank.
(ii)
Have pump-out accomplished for all such systems and provide written proof to the King George County Administrator that the system has been pumped by a licensed septic hauler on a form and in the manner set forth by the Administrator at least once every five years.
1.
In lieu of being required to provide proof of septic tank pump-out every five years, the property owner may submit documentation every five years, certified by an operator or on-site soil evaluator (OSE) licensed or certified under Chapter 23 (§ 54.1-2300 et seq.) of Title 54.1 as being qualified to operate, maintain, or design on-site sewage systems that the septic system has been inspected and is functioning properly, and that the tank does not need to have the effluent pumped out of it.
(6)
A reserve sewage disposal site with a capacity at least equal to that of the primary sewage disposal site shall be provided, in accordance with the King George County On-Site Sewage Disposal Ordinance.
(i)
This requirement shall not apply to any lot or parcel recorded prior to October 1, 1989, if such lot or parcel is not sufficient in capacity to accommodate a reserve sewage disposal site, as determined by the local Health Department.
1.
For any lot or parcel that has recorded adjustments or divisions after October 1, 1989, and resulted in a change to the original footprint of the recorded lot or parcel, the most recent recorded plat shall govern and must comply with 5-2-7 (6), above.
(ii)
Building or construction of any impervious surface shall be prohibited on the area of all sewage disposal sites or on an onsite sewage treatment system which operates under a permit issued by the State Water Control Board, until the structure is served by public sewer.
(7)
Any Chesapeake Bay Preservation Act Land Disturbing Activity that is determined by the County to be grandfathered in accordance with Chapter 5.5, Environment, of the King George County Code shall comply with performance based or technology based technical criteria set forth below:
(i)
Performance-based criteria. For land-disturbing activities, the calculated post-development nonpoint source pollutant runoff load shall be compared to the calculated predevelopment load based upon the average land cover condition or the existing site condition. A BMP shall be located, designed, and maintained to achieve the target pollutant removal efficiencies specified in 9VAC25-870-96 C of the Virginia Stormwater Management Program (VSMP) regulations.
(ii)
Technology-based criteria. For land-disturbing activities, the post-developed stormwater runoff from the impervious cover shall be treated by an appropriate BMP as required by the post-developed condition percent impervious cover as specified in Table 1 of 9VAC25-870-96 C. The selected BMP shall be located, designed, and maintained to perform at the target pollutant removal efficiency specified in 9VAC25-870-96 C of the Virginia Stormwater Management Program (VSMP) regulations or those found in 9VAC25-870-65 of the VSMP regulations.
(8)
Prior to initiating grading or other on-site activities on any portion of a lot or parcel, all wetlands permits required by federal, state, and local laws and regulations shall be obtained and evidence of such submitted to the Administrator, in accordance with Section 5-2-8, Plan of Development, of this Article.
(9)
Land upon which agricultural activities are being conducted, including but not limited to crop production, pasture, and dairy and feedlot operations, or lands otherwise defined as agricultural land by King George County, shall have a soil and water quality conservation assessment conducted that evaluates the effectiveness of existing practices pertaining to soil erosion and sediment control, nutrient management, and management of pesticides, and, where necessary, results in a plan that outlines additional practices needed to ensure that water quality protection is being accomplished consistent with the Act and this chapter.
(i)
Recommendations for additional conservation practices need address only those conservation issues applicable to the tract or field being assessed. Any soil and water quality conservation practices that are recommended as a result of such an assessment and are subsequently implemented with financial assistance from federal or state cost-share programs must be designed, consistent with cost-share practice standards effective in January 1999 in the "Field Office Technical Guide," as amended, of the U.S. Department of Agriculture Natural Resource Conservation Service or the June 2000 edition of the "Virginia Agricultural BMP Manual," as amended, of the Virginia Department of Conservation and Recreation, respectively. Unless otherwise specified in this section, general standards pertaining to the various agricultural conservation practices being assessed shall be as follows:
1.
For erosion and sediment control recommendations, the goal shall be, where feasible, to prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996, as amended, in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service. However, in no case shall erosion exceed the soil loss consistent with an Alternative Conservation System, referred to as an "ACS", as defined in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service.
2.
For nutrient management, whenever nutrient management plans are developed, the operator or landowner must provide soil test information, consistent with the Virginia Nutrient Management Training and Certification Regulations (4VAC50-85).
3.
For pest chemical control, referrals shall be made to the local cooperative extension agent or an Integrated Pest Management Specialist of the Virginia Cooperative Extension Service. Recommendations shall include copies of applicable information from the "Virginia Pest Management Guide", or other Extension materials related to pest control.
(ii)
A higher priority shall be placed on conducting assessments of agricultural fields and tracts adjacent to RPAs. However, if the landowner or operator of such a tract also has RMA fields or tracts in his operation, the assessment for that landowner or operator may be conducted for all fields or tracts in the operation. When such an expanded assessment is completed, priority must return to RPA fields and tracts.
(iii)
The findings and recommendations of such assessments and any resulting soil and water quality conservation plans will be submitted to the local Soil and Water Conservation District Board which will be the plan-approving authority.
(D)
Buffer Area Requirements. To minimize the adverse effects of human activities on the other components of Resource Protection Areas (RPA), state waters, and aquatic life, a 100-foot buffer area of vegetation that is effective in retarding runoff, preventing erosion, and filtering non-point source pollution from runoff shall be retained if present and established where it does not exist.
(1)
The buffer area shall be located adjacent to and landward of other RPA components and along both sides of any water body with perennial flow. The full buffer area shall be designated as the landward component of the RPA, in accordance with Sections 5-2-1, Applicability, and Section 5-2-8, Plan of Development, of this Article.
(i)
The buffer area shall be designed to follow the length of all RPA components on the site and shall not be designed to be clustered but spread out to achieve a true buffer that prevents erosion.
(ii)
Where feasible, the buffer area shall include flora that is native to King George County.
(2)
Where land uses such as agriculture or silviculture within the area of the buffer cease and the lands are proposed to be converted to other uses, the full 100-foot-wide buffer shall be reestablished. In reestablishing the buffer, management measures shall be undertaken to provide woody vegetation that assures the buffer functions as set forth in this Article.
(3)
When replanting is required to establish a buffer, a combination of trees, groundcover, and shrubs with a demonstrated ability to improve water quality shall meet the intent of the buffer area.
(4)
The 100-foot buffer area shall be deemed to achieve a 75% reduction of sediments and a 40% reduction of nutrients.
(5)
The buffer area shall be maintained to meet the following additional performance standards:
(i)
To maintain the functional value of the buffer area, indigenous vegetation may be removed subject to approval by the Administrator only to provide for reasonable sight lines, access paths, general woodlot management, and best management practices including those that prevent upland erosion and concentrated flows of storm water, as follows:
1.
Trees may be pruned or removed as necessary to provide for sight lines and vistas provided that where removed, they shall be replaced with other vegetation that is equally effective in retarding runoff, preventing erosion, and filtering non-point source pollution from runoff.
2.
Any path shall be constructed to effectively control erosion.
3.
Dead, diseased, or dying trees or shrubbery and noxious weeds (including, but not limited to, Japanese Stiltgrass, Phragmites, Johnson Grass, Kudzu and Multiflora Rose) may be removed and thinning of trees may be allowed, pursuant to sound horticultural practice incorporated into locally adopted standards.
4.
For shoreline erosion control projects, trees and woody vegetation may be removed, necessary control techniques employed, and appropriate vegetation established to protect or stabilize the shoreline in accordance with the best available technical advice and applicable permit conditions or requirements.
(ii)
When the application of the buffer areas would result in the loss of a buildable area on a lot or parcel recorded prior to October 1, 1989, the Administrator may authorize encroachments into the buffer area in accordance with Section 5-2-8, Plan of Development, and the following criteria:
1.
Encroachments into the buffer areas shall be the minimum necessary to achieve a reasonable buildable area for a principal structure and necessary utilities;
2.
Where practicable, a vegetated area that will maximize water quality protection, mitigate the effects of the buffer encroachment, and is at a minimum equal to the area of encroachment into the buffer area shall be established elsewhere on the lot or parcel; and
3.
The encroachment may not extend into the seaward 50 feet of the buffer area.
(iii)
On agricultural lands, the agricultural buffer area shall be managed to prevent concentrated flows of surface water from breaching the buffer area and appropriate measures may be taken to prevent noxious weeds (including, but not limited to, Japanese Stiltgrass, Phragmites, Johnson Grass, Kudzu and Multiflora Rose) from invading the buffer area. Agricultural activities may encroach into the buffer area as follows:
1.
Agricultural activities may encroach into the landward 50 feet of the 100-foot wide buffer area when at least one agricultural best management practice which, in the opinion of the local soil and water conservation district board, addresses the more predominant water quality issue on the adjacent land erosion control or nutrient management is being implemented on the adjacent land, provided that the combination of the undisturbed buffer area and the best management practice achieves water quality protection, pollutant removal, and water resource conservation at least the equivalent of the 100-foot wide buffer area. If nutrient management is identified as the predominant water quality issue, a nutrient management plan, including soil tests, must be developed consistent with the Virginia Nutrient Training and Certification Regulations (4 VAC 5-15) administered by the Virginia Department of Conservation and Recreation.
2.
Agricultural activities may encroach within the landward 75 feet of the 100-foot-wide buffer area when Agricultural Best Management Practices, which address erosion control, nutrient management, and pest chemical control, are being implemented on the adjacent land. The erosion control practices must prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996 in the "Field Office Technical Guide," as amended, of the U.S. Department of Agriculture Natural Resource Conservation Service. A nutrient management plan, including soil tests, must be developed, consistent with the Virginia Nutrient Management Training and Certification Regulations (4 VAC 5-15) administered by the Virginia Department of Conservation and Recreation. In conjunction with the remaining buffer area, this collection of best management practices shall be presumed to achieve water quality protection at least the equivalent of that provided by the 100-foot-wide buffer area.
3.
The buffer area is not required to be designated adjacent to agricultural drainage ditches if at least one best management practice which, in the opinion of the local Soil and Water Conservation District Board, addresses the more predominant water quality issue on the adjacent land either erosion control or nutrient management is being implemented on the adjacent land.
4.
If specific problems are identified pertaining to agricultural activities which are causing pollution of the nearby water body with perennial flow or violate performance standards pertaining to the vegetated buffer area, the Administrator, in cooperation with Soil and Water Conservation District, shall recommend a compliance schedule to the landowner and require the problems to be corrected consistent with that schedule. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.
5.
In cases where the landowner or his agent or operator has refused assistance from the Soil and Water Conservation District in complying with or documenting compliance with the agricultural requirements of this chapter, the District shall report the noncompliance to the Director of the King George County Department of Community Development. The Director shall require the landowner to correct the problems within a specified period of time not to exceed 18 months from their initial notification of the deficiencies to the landowner. King George County, in cooperation with the District, shall recommend a compliance schedule to the landowner. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.
(A)
Purpose and Intent. The purpose of the water quality impact assessment (WQIA) is to:
(1)
Identify the impacts of proposed land disturbance, development or redevelopment on water quality and lands within RPAs;
(2)
Ensure that, where land disturbance, development, or redevelopment does take place within RPAs and other sensitive lands, it will be located on those portions of a site and in a manner that will be least disruptive to the natural functions of RPAs and other sensitive lands;
(3)
Protect individuals from investing funds for improvements proposed for location on lands unsuited for such development because of high ground water, erosion, or vulnerability to flood and storm damage;
(4)
Provide for administrative relief from the terms of this Article when warranted and in accordance with the requirements contained herein; and
(5)
Specify mitigation which will address water quality protection.
(B)
Water Quality Impact Assessment (WQIA) Required. A WQIA is required for:
(1)
Any proposed land disturbance, development, or redevelopment within an RPA, including any buffer area modification or encroachment as provided for in Section 5-2-6, Performance Standards, of this Article; or
(2)
Any development in an RMA as deemed necessary by the Administrator due to the unique characteristics of the site or intensity of the proposed development.
(C)
Two Levels of Assessment. There shall be two levels of WQIA: a minor assessment and a major assessment.
(D)
Minor WQIA.
(1)
A minor WQIA pertains only to land disturbance, development, or redevelopment within CBPAs, which causes no more than 5,000 sq. ft. of land disturbance within CBPAs and proposes any encroachment into the landward 50 ft. of the 100-foot buffer area as permitted under Section 5-2-7 (D)(5)(ii). A minor assessment must demonstrate through acceptable calculations that the buffer area, enhanced vegetation, and necessary best management practices will result in removal of no less than 75% of sediments and 40% of nutrients from post-development stormwater runoff. A minor assessment shall include a site drawing to scale, which shows the following:
(i)
Location of the components of the RPA, including the 100-foot buffer area;
(ii)
Location and nature of the proposed encroachment into the buffer area, including type of paving material; areas of clearing or grading; location of any structures, drives, or other impervious cover; and sewage disposal systems or reserve drainfield sites; and
(iii)
Type and location of proposed best management practices to mitigate the proposed encroachment.
(E)
Major WQIA.
(1)
A major WQIA shall be required for any land disturbance, development, or redevelopment which:
(i)
Exceeds 5,000 square feet of land disturbance within CBPAs and proposes to encroach into the landward 50 ft. of the 100-foot buffer area;
(ii)
Disturbs any portion of the buffer area within 50 feet of any other component of an RPA; or
(iii)
Is located solely in an RMA and is deemed necessary by the Administrator.
(2)
The information required in this section shall be considered a minimum, unless the Administrator determines that some of the elements are unnecessary due to the scope and nature of the proposed use and development of land.
(3)
The following elements shall be included in the preparation and submission of a major WQIA:
(i)
All the information required in a minor WQIA, as specified in Section 5-2-7 (D);
(ii)
A hydrogeological element that:
1.
Describes the existing topography, soils, hydrology, and geology of the site and adjacent lands.
2.
Describes the impacts of the proposed development on topography, soils, hydrology, and geology on the site and adjacent lands.
3.
Indicates the following:
i.
Disturbance or destruction of wetlands and justification for such action;
ii.
Disruptions or reductions in the supply of water to wetlands, streams, lakes, rivers, or other water bodies;
iii.
Disruption to existing hydrology including wetland and stream circulation patterns;
iv.
Source location and description of proposed fill material;
v.
Location of dredge material and location of dumping area for such material;
vi.
Estimation of pre- and post-development pollutant loads in runoff;

This Division is adopted pursuant to the authority granted to localities by the Code of Virginia §15.2-2280, as amended, and may be referred to as the King George County Floodplain Management Overlay District, floodplain overlay, or flood hazard overlay.
These provisions shall apply to all lands within the jurisdiction of King George County and identified as special flood hazard areas (SFHAs) identified by the County or shown on the flood insurance rate map (FIRM) or included in the flood insurance study (FIS) that are provided to the County by the Federal Emergency Management Agency (FEMA).
(A)
No land shall hereafter be developed, and no structure shall be located, relocated, constructed, reconstructed, enlarged, or structurally altered except in full compliance with the terms and provisions of this Division and Article, and any other applicable ordinances and regulations which apply to uses within the jurisdiction of this ordinance.
(B)
The degree of flood protection sought by the provisions of this Division is considered reasonable for regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur on rare occasions. Flood heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This Division does not imply that areas outside the floodplain area or that land uses permitted within such area will be free from flooding or flood damages.
(C)
This Division shall not create liability on the part of King George County or any officer or employee thereof for any flood damages that result from reliance on this Division, or any administrative decision lawfully made there under.
(A)
This Division supersedes any locally adopted flooding regulations currently in effect in flood-prone districts. Any regulations, however, shall remain in full force and effect to the extent that its provisions are more restrictive.
(B)
These regulations are not intended to repeal or abrogate any existing ordinances including subdivisions, zoning ordinances, or building codes. In the event of a conflict between these regulations and any other ordinance, the more restrictive shall govern.
(A)
Any person who fails to comply with any of the requirements or provisions of this Division, or directions of the Administrator, or any other authorized employee of the King George County, shall be subject to the penalties pursuant to the Code of Virginia, and as outlined in the VA Uniform Statewide Building Code (USBC) for building code violations and Article II, Division 4, Enforcement, of the King George County Zoning Ordinance for violations and associated penalties.
(B)
In addition to the above penalties, all other actions are hereby reserved, including an action in equity for the proper enforcement of this Division. The imposition of a fine or penalty for any violation of, or noncompliance with, this Division shall not excuse the violation or noncompliance or permit it to continue; and all such persons shall be required to correct or remedy such violations within a reasonable time. Any structure constructed, reconstructed, enlarged, altered, or relocated in noncompliance with this Division may be declared by the County to be a public nuisance and abatable as such. Flood insurance may be withheld from structures constructed in violation of this Division.

(i)
Provide a map that clearly delineates the new corporate boundaries or the new area for which the authority to regulate pursuant to these regulations has either been assumed or relinquished through annexation; and
(ii)
If the FIRM for any annexed area includes special flood hazard areas that have flood zones that have regulatory requirements that are not set forth in these regulations, prepare amendments to these regulations to adopt the FIRM and appropriate requirements, and submit the amendments to the governing body for adoption; such adoption shall take place at the same time as or prior to the date of annexation and a copy of the amended regulations shall be provided to DCR and FEMA.
(17)
Upon the request of FEMA, complete and submit a report concerning participation in the NFIP, which may request information regarding the number of buildings in the SFHA, number of permits issued for development in the SFHA, and number of variances issued for development in the SFHA.
(18)
It is the duty of the Administrator to consider flood, mudslide, and flood-related erosion hazards, to the extent that they are known, in all official actions relating to land management and use throughout the entire jurisdictional area of the County, whether or not those hazards have been specifically delineated geographically (e.g., via mapping or surveying).
Records of actions associated with administering this Division shall be kept on file and maintained by the Administrator or their designee.
(A)
The Administrator shall make interpretations, where needed, as to the exact location of SFHA, floodplain boundaries, and floodway boundaries. The following shall apply to the use and interpretation of FIRMs and data:
(1)
Where field surveyed topography indicates that adjacent ground elevations:
(i)
Are below the base flood elevation in riverine SFHAs, or are below the 1% storm surge elevation in coastal SFHAs, even in areas not delineated as a SFHA on a FIRM, the area shall be considered as a SFHA and subject to the requirements of these regulations; or
(ii)
Are above the base flood elevation, the area shall be regulated as a SFHA unless the applicant obtains a LOMC that removes the area from the SFHA.
(2)
In FEMA-identified SFHAs where base flood elevation and floodway data have not been identified and in areas where FEMA has not identified SFHAs, any other flood hazard data available from a federal, state, or other source shall be reviewed and reasonably used.
(3)
Base flood elevations and designated floodway boundaries on FIRMs and in FISs shall take precedence over base flood elevations and floodway boundaries by any other sources if such sources show reduced floodway widths and/or lower base flood elevations.
(4)
Other sources of data shall be reasonably used if such sources show increased base flood elevations and/or larger floodway areas than are shown on FIRMs and in FISs.
(5)
If a preliminary FIRM and/or a preliminary FIS has been provided by FEMA:
(i)
Upon the issuance of a Letter of Final Determination (LOFD) by FEMA, the preliminary flood hazard data shall be used and shall replace the flood hazard data previously provided from FEMA for the purposes of administering these regulations.
(ii)
Prior to the issuance of a LOFD by FEMA, the use of preliminary flood hazard data shall be deemed the best available data pursuant to Section 5-3-14 (A)(3)(iii) as defined by this Division and used where no base flood elevations and/or floodway areas are provided on the effective FIRM.
(iii)
Prior to issuance of a LOFD by FEMA, the use of preliminary flood hazard data is permitted where the preliminary base flood elevations or floodway areas exceed the base flood elevations and/or designated floodway widths in existing flood hazard data provided by FEMA. Such preliminary data may be subject to change and/or appeal to FEMA.
(A)
The County floodplain overlay in effect on the date of annexation shall remain in effect and shall be enforced by the municipality for all annexed areas until the municipality adopts and enforces an ordinance which meets the requirements for participation in the NFIP. Municipalities with existing floodplain ordinances shall pass a resolution acknowledging and accepting responsibility for enforcing floodplain ordinance standards prior to annexation of any area containing identified flood hazards. If the FIRM for any annexed area includes SFHAs with flood zones that have regulatory requirements that are not set forth in these regulations, the governing body shall prepare amendments to these regulations to adopt the FIRM and appropriate requirements, and submit the amendments to the governing body for adoption; such adoption shall take place at the same time as or prior to the date of annexation and a copy of the amended regulations shall be provided to DCR Division of Dam Safety and Floodplain Management and FEMA.
(B)
In accordance with the Code of Federal Regulations, Title 44 Subpart (B) Section 59.22(a)(9)(v), all NFIP participating communities must notify the Federal Insurance Administration and optionally the state coordinating office in writing whenever the boundaries of the community have been modified by annexation or the community has otherwise assumed or no longer has authority to adopt and enforce floodplain management regulations for a particular area.
(C)
To ensure that all FIRMs accurately represent the community's boundaries, a copy of a map of the community suitable for reproduction, clearly delineating the new corporate limits or new area for which the community has assumed, or relinquished floodplain management regulatory authority must be included with the notification.
The delineation of the Floodplain Management District may be revised by the King George County Board of Supervisors where natural or man-made changes have occurred and/or where more detailed studies have been conducted or undertaken by the U.S. Army Corps of Engineers or other qualified agency or an individual documents the need for such change. However, prior to any such change, approval must be obtained from FEMA. An approved Letter of Map Revision (LOMR) serves as record of this change.
Initial interpretations of the boundaries of the Floodplain Management Overlay shall be made by the Administrator or designee. Should a dispute arise concerning the boundaries of any of the districts, the BZA shall make the necessary determination in accordance with Article III, Permits and Applications, of this Ordinance. The person questioning or contesting the location of the district boundary shall be given a reasonable opportunity to present their case to the BZA and to submit his own technical evidence if they so desire.
(A)
When development in the floodplain will cause or causes a change in the base flood elevation, the applicant, including state agencies, must notify FEMA by applying for a Conditional Letter of Map Revision (CLOMR) or a LOMR. Examples include:
(1)
Any development that causes a rise in the base flood elevations within the floodway.
(2)
Any development occurring in zone AE without a designated floodway, which will cause a rise of more than one foot in the base flood elevation.
(3)
Alteration or relocation of a stream (including but not limited to installing culverts and bridges) 44 CFR 65.3 and 65.6(a)(12).
(A)
Basis of flood hazard zones. The various flood hazard zones shall include special flood hazard areas (SFHA). The basis for the delineation of these zones shall be the FIS and the FIRM for King George County, Virginia, and incorporated areas prepared by FEMA, Federal Insurance Administration, dated December 2, 2021, and any subsequent revisions or amendments thereto.
(1)
King George County may identify and regulate local flood hazard or ponding areas that are not delineated on the FIRM. These areas may be delineated on a "Local Flood Hazard Map" using best available topographic data and locally derived information such as flood of record, historic high-water marks, or approximated study methodologies.
(2)
The boundaries of the SFHA and flood hazard zones are established as shown on the FIRM which is declared to be a part of this Division, and which shall be kept on file at the King George County Community Development offices.
(3)
The flood hazard zones described below shall constitute the Floodplain Management Overlay District. It shall be an overlay to the existing underlying zoning districts as shown on the official zoning ordinance map, and as such, the provisions for the Floodplain Management Overlay District shall serve as a supplement to the underlying district provisions.
(i)
AE Zone. Those areas with at least a 1% annual chance of being flooded. Also includes the "Coastal A Zone," which are areas that are subject to wave heights between 1.5 feet and 3 feet. AE zones have two categories, defined below:
1.
Category 1 areas on the FIRM accompanying the FIS are delineated for purposes of this Division using the criteria that certain areas within the floodplain must be capable of carrying the water of the base flood without increasing the water surface elevation of that flood more than one foot at any point. These areas included in this district are specifically defined in Table 2 of the King George County FIS and shown on the accompanying FIRM on file with the King George County Community Development offices. Category 1 areas shall be those areas for which one-percent annual chance flood elevations have been provided and the floodway has been delineated.
2.
Category 2 areas on the FIRM accompanying the FIS shall be those areas for which one-percent annual chance flood elevations have been provided and the floodway has not been delineated.
(ii)
AH Zone. Those areas on the FIRM accompanying the FIS with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones; for the purposes of elevation and construction standards of Section 5-3-17, the AH Zone shall be considered a Category 2 area.
(iii)
A Zone. Those areas known as the Approximated Floodplain Areas, for which no detailed flood profiles or elevations are provided, but the one percent annual chance floodplain boundary has been approximated. For these areas, the base flood elevations and floodway information from Federal, State, and other acceptable sources shall be used, when available [44 CFR 60.3(b)]. Where the specific one percent annual chance flood elevation cannot be determined for this area using other sources of data, such as the U.S. Army Corps of Engineers Floodplain Information Reports, U.S. Geological Survey Flood-Prone Quadrangles, etc., then the applicant for the proposed use, development and/or activity shall determine this base flood elevation. The elevation shall be determined by using the elevation of a point on the boundary of the identified floodplain area which is nearest the construction site. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by the Administrator.
(iv)
AO Zone. Those areas of shallow flooding identified as AO on the FIRM.
(v)
VE or V Zones. Those areas that are known as Coastal High Hazard Areas, extending from offshore to the inland limit of a primary frontal dune along an open coast or other areas subject to high velocity waves.
(vi)
X Zone. Other flood districts shall be those areas identified as Zone X on the maps accompanying the flood insurance study. This zone includes areas of 0.2% annual chance flood or areas of 1% annual chance flood with average depths of less than one foot or with drainage areas less than one square mile.
(4)
Where the specific base flood elevation cannot be determined for this area using other sources of data, such as the U.S. Army Corps of Engineers Flood Plain Information Reports, U.S. Geological Survey Flood-prone Quadrangles, etc., then the applicant for the proposed use, development and/or activity shall determine this elevation in accordance with hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by King George County.
(A)
Permit requirement.
(1)
All uses, activities and, development occurring within the Floodplain Management Overlay shall be undertaken only upon the issuance of a permit. Such development shall be undertaken only in strict compliance with the provisions of this Division and with all other applicable codes and ordinances, as amended, such as the VA USBC and the King George County Zoning and Subdivision Ordinance. Prior to the issuance of any such permit, the Administrator shall require all applications to include compliance with all applicable state and federal laws and shall review all sites to assure they are reasonably safe from flooding. Under no circumstances shall any use, activity and/or development adversely affect the capacity of the channels or floodways or any watercourse, drainage ditch or any other drainage facility or system.
(2)
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 U.S. Army Corps of Engineers, the Virginia Marine Resources Commission, and the Virginia State Water Control Board. Further notification of the proposal shall be given to all adjacent jurisdictions, the Division of Dam Safety and Flood Plain Management at the Department of Conservation and Recreation and the Federal Emergency Management Agency.

(12)
The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters expected at the site;
(13)
The repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure;
(14)
Variances will not be issued for any accessory structure within the SFHA; and
(15)
Such other factors which are relevant to the purposes of this ordinance.
(D)

OVERLAY ZONING DISTRICTS
(A)
Overlay Zoning Districts Establishment and Purpose. This article establishes overlay districts, which apply additional standards to the development and design requirements of land in the County. These district standards exist as overlays to the existing underlying zoning districts, and, as such, the provisions for the overlay districts do not replace, but shall serve to supplement the underlying district provisions. King George County is hereby divided into the following overlay zoning districts:
Table V-1. Overlay Zoning Districts
(A)
Chesapeake Bay Preservation Area Overlay (CBPA).
(1)
Findings of Fact. The Chesapeake Bay, along with its tributaries, is one of the most important and productive estuarine systems in the world, providing economic and social benefits to the citizens of King George County and the Commonwealth of Virginia. The health of the Bay is vital to maintaining King George County's economy and the welfare of its citizens.
(2)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including non-point source pollution from land uses and development. Existing high-quality waters are worthy of protection from degradation to guard against further pollution. Certain lands that are proximate to shorelines have intrinsic water quality value due to the ecological and biological processes they perform. Other lands have severe development constraints from flooding, erosion, and soil limitations. With proper management, they offer significant ecological benefits by providing water quality maintenance and pollution control, as well as flood and shoreline erosion control. These lands together, designated by the Board of Supervisors as Chesapeake Bay Preservation Areas (hereinafter "CBPAs"), need to be protected from destruction and damage to protect the quality of water in the Bay and consequently the quality of life in King George County and the Commonwealth of Virginia.
(3)
Applicability. All land within King George County is designated as a Chesapeake Bay Preservation Area (CBPA) and is either classified as a Resource Protection Areas (RPA) or a Resource Management Area (RMA). Adherence to the CBPA regulations provided in this Division is required for all lots and parcels within King George County.
(4)
Purpose. This ordinance is enacted to implement the requirements of §62.1-44.15:67, et seq. of the Code of Virginia (The Chesapeake Bay Preservation Act). The purpose of the Chesapeake Bay Preservation Overlay is to:
(i)
Protect existing high-quality state waters;
(ii)
Restore all other state waters to a condition or quality that will permit all reasonable public uses and will support the propagation and growth of all aquatic life, including game fish, which might reasonably be expected to inhabit them;
(iii)
Safeguard the clean waters of the Commonwealth from pollution;
(iv)
Prevent any increase in pollution;
(v)
Reduce existing pollution; and
(vi)
Promote water resource conservation to provide for the health, safety, and welfare of the present and future citizens of King George County.
(5)
Unless otherwise stated in this Article, the review and approval procedures provided for in Article 3 of this Ordinance and Chapters 4 (Building and Building Regulations), Chapter 6 (Erosion and Settlement Control), and Chapter 5.5 (Wetlands and Stormwater Ordinances) of the County Code shall be followed in reviewing and approving development, redevelopment, and uses governed by these Chesapeake Bay Preservation Overlay regulations.
(B)

(1)
Purpose. The purpose of the floodplain management overlay provisions are to prevent:
(i)
The loss of life and property;
(ii)
The creation of health and safety hazards;
(iii)
The disruption of commerce and governmental services;
(iv)
The extraordinary and unnecessary expenditure of public funds for flood protection and relief; and
(v)
The impairment of the tax base by:
1.
Requiring all those uses, activities, and developments that do occur in flood-prone areas to be protected and/or flood-proofed against flooding and flood damage;
2.
Regulating uses, activities, and development which, alone or in combination with other existing or future uses, activities, and development, will cause unacceptable increases in flood heights, velocities, and frequencies;
3.
Restricting or prohibiting certain uses, activities, and development from locating within areas subject to flooding; and
4.
Protecting individuals from buying land and structures, which are unsuited for intended purposes because of flood hazards.
(C)
Highway Corridor Overlay (HCOD).
(1)
Purpose. The purpose of the HCOD is to:
(i)
Maintain the long-term safety and mobility function of Route 3 and Route 301;
(ii)
Limit the number of conflict points, thereby reducing the need for additional crossover locations and traffic signals;
(iii)
Promote improved pedestrian and vehicular circulation;
(iv)
Encourage land assembly and the most desirable use of land in accordance with the King George County Comprehensive Plan;
(v)
Encourage designs which produce a desirable relationship between individual buildings, the circulation systems and adjacent areas;
(vi)
Control signage, visibility obstructions and clutter; and
(vii)
Permit a flexible response of development to market factors as well as to provide incentives for development of a variety of land uses and activities of high quality.
(D)
Military Compatibility Area Overlay District (MCAOD).
(1)
Purpose. The purpose of Military Compatibility Area Overlay District (MCAOD) is to:
(i)
Recognize the existence of Naval Support Facility Dahlgren (NSF) and address the interaction between NSF Dahlgren and surrounding land uses;
(ii)
Support NSF Dahlgren as a valuable economic development asset in the community;
(iii)
Protect public's health, safety, welfare, quality of life, and the economic stability of the County;
(iv)
Ensure that prospective buyers and developers of real estate in the vicinity of NSF Dahlgren are aware of the presence of the facility, their operations, and the potential impacts that they may have;
(v)
Protect the integrity of the operations and continued existence of NSF Dahlgren by establishing and delineating a geographic area which is subject to compatibility requirements caused by activities related to the normal operations of such facilities; and
(vi)
Promote an orderly transition between community and military land uses so that land uses remain compatible.
(A)
The Chesapeake Bay Preservation Area Overlay (CBPA) shall apply to all lands identified as Chesapeake Bay Preservation Areas (CBPAs) as designated by the Board of Supervisors and as shown on the Chesapeake Bay Map. The Chesapeake Bay Map, together with all explanatory matter thereon, is hereby adopted by reference and declared to be a part of this Article. The Chesapeake Bay Map shows the general location of CBPAs and should be consulted by persons contemplating activities within King George County prior to engaging in a regulated activity.
(B)
All area within the County (CPBA) is either designated as a Resource Protection Area (RPA) or as a Resource Management Area (RMA). Components of the CBPA include the following:
(1)
The Resource Protection Area (RPA), including:
(i)
Tidal wetlands;
(ii)
Nontidal wetlands connected by surface flow and contiguous to tidal wetlands or water bodies with perennial flow;
(iii)
Tidal shores; and
(iv)
A 100-foot vegetated buffer area located adjacent to and landward of the components listed in subsections i through iii, above, and along both sides of any water bodies with perennial flow.
(2)
The Resource Management Area (RMA), including:
(i)
The remaining area of the County that is not identified as being within the RPA.
(C)
Portions of RPAs and RMAs designated by the Board of Supervisors as Intensely Developed Areas (IDA) shall serve as redevelopment areas. Areas so designated shall comply with all erosion and sediment control requirements and the performance standards for redevelopment in Section 5-2-6, Performance Standards.
(A)
Interpretation of Resource Protection Area (RPA) Boundaries shall be made as follows:
(1)
Delineation by the Applicant. The site-specific boundaries of the RPA shall be determined by the applicant through the performance of an environmental site assessment as part of the Plan of Development Process or Water Quality Impact Assessment (WQIA), subject to approval by the Administrator and in accordance with Section 5-2-8, Plan of Development, and Section 5-2-7, Water Quality Impact Assessment, of this Article. The CBPA Overlay Map shall be used as a guide to the general location of RPAs; however, this does not relieve the applicant of the requirement that they perform site-specific determination of the RPA.
(2)
Delineation by the Zoning Administrator. The Administrator may waive the requirement for an environmental site assessment and perform the delineation, when requested by an applicant wishing to construct a single-family dwelling. The Administrator may use hydrology, soils, plant species, and other data, and consult other appropriate resources as needed to perform the delineation.
(3)
Delineation Confirmation or Conflict. Where the applicant has provided a site-specific delineation of the RPA, the Administrator will verify the accuracy of the boundary delineation. In determining the site-specific RPA boundary, the Administrator may render adjustments to the applicant's boundary delineation, in accordance with Section 5-2-8, Plan of Development. In the event the adjusted boundary delineation is contested by the applicant, the applicant may seek relief, in accordance with the provisions of Section 5-2-10, Denial/Appeal of Plan.
In any case where the requirements of this Article conflict with any other provision of the King George County Code or existing state or federal regulations, whichever imposes the more stringent restrictions shall apply.
Permitted uses, Special Exception uses, accessory uses, and special requirements shall be as established by the underlying zoning district, unless specifically modified by the requirements set forth herein.
Lot size shall be subject to the requirements of the underlying zoning district(s), provided that any lot shall have sufficient area outside the RPA to accommodate an intended development, in accordance with the performance standards in Section 5-2-6, when such development is not otherwise allowed in the RPA.
(A)
Purpose and Intent. The performance standards establish the means to minimize erosion and sedimentation potential, reduce land application of nutrients and toxins, and maximize rainwater infiltration. Natural ground cover, especially woody vegetation, is most effective in holding soil in place and preventing site erosion. Indigenous vegetation, with its adaptability to local conditions without the use of harmful fertilizers or pesticides, filters stormwater runoff. Minimizing impervious cover enhances rainwater infiltration and effectively reduces stormwater runoff potential. The purpose and intent of these requirements are also to implement the following objectives:
(1)
Prevent a net increase in non-point source pollution from new development;
(2)
Achieve a 10% reduction in non-point source pollution from redevelopment; and
(3)
Achieve a 40% reduction in non-point source pollution from agricultural uses.
(B)
Required Conditions.
(1)
All development and redevelopment equal to or greater than 2,500 square feet of land disturbance shall be subject to a plan of development process, including the approval of a site plan or a subdivision plat in accordance with the provisions of the Zoning and Subdivision Ordinance unless otherwise provided for.
(2)
Development in RPAs may be allowed only if it: (i) is water-dependent; or (ii) constitutes redevelopment meeting the criteria provided below:
(i)
A new or expanded water-dependent facility may be allowed provided that the following criteria are met:
1.
It does not conflict with the Comprehensive Plan;
2.
It complies with the performance criteria set forth in Section 5-2-6 of this Article;
3.
Any non-water-dependent component is located outside of the RPA; and
4.
Access to the water-dependent facility will be provided with the minimum disturbance necessary. Where practicable, a single point of access will be provided.
(ii)
Redevelopment on isolated redevelopment sites outside of an area designated by King George County to be an IDA shall be permitted only if there is no increase in the amount of impervious cover and no further encroachment within the RPA and shall conform to the stormwater management criteria set forth in the Erosion and Sediment Control Law and the Virginia Stormwater Management Act and their attendant regulations, as well as all applicable stormwater management requirements of other state and federal agencies.
(iii)
Roads and Driveways not exempt under subdivision B 1 of 9VAC25-830-150 and which, therefore, must comply with the provisions of the following:
1.
The Administrator makes a finding that there are no reasonable alternatives to aligning the road or driveway in or across the RPA;
2.
The alignment and design of the road or driveway are optimized, consistent with other applicable requirements, to minimize (i) encroachment of the RPA and (ii) adverse effects of on water quality;
3.
The design and construction of the road or driveway satisfy all applicable criteria of this Ordinance, including submission of a water quality impact assessment; and
4.
The Administrator reviews the plan for the road or driveway proposed in or across the RPA in coordination with other local government, state, federal requirements, and development approvals.
5.
The plan for the road or driveway proposed in or across the RPA shall be coordinated with either a Site Plan in accordance with Article III, Permits and Applications, of this Ordinance, or a subdivision submittal in accordance with Article X, Subdivision, of this Ordinance.
(iv)
Flood control and stormwater management facilities that drain or treat water from multiple development projects, or from a significant portion of a watershed, may be allowed in an RPA provided such facilities are allowed and constructed in accordance with the Virginia Stormwater Management Act and its attendant regulations, and provided that:
1.
The local government has conclusively established that location of the facility within the RPA is the optimum location;
2.
The size of the facility is the minimum necessary to provide necessary flood control or stormwater treatment, or both;
3.
The facility must be consistent with a comprehensive stormwater management plan developed and approved in accordance with Chapter 5.5, Environment, of the King George County Code;
4.
All applicable permits for construction in state or federal waters must be obtained from the appropriate state and federal agencies, such as the U.S. Army Corps of Engineers, the department, and the Virginia Marine Resources Commission;
5.
Approval must be received from the local government prior to construction; and
6.
Routine maintenance is allowed to be performed on such facilities to assure that they continue to function as designed. It is not the intent of this subdivision to allow a best management practice that collects and treats runoff from only an individual lot or some portion of the lot to be located within an RPA.
(3)
A Water Quality Impact Assessment (WQIA) shall be required for any proposed use, land disturbance, development, or redevelopment within RPAs and for any development within RMAs when required by the Administrator, as provided in Section 5-2-7 of this Article.

(iii)
Diseased trees or trees weakened by age, storm, or other injury may be removed, when approved by the Administrator. Other woody vegetation on site shall also be preserved outside the approved construction footprint.
(iv)
Prior to clearing or grading, suitable protective barriers, such as safety fencing, shall be erected 5 ft. outside of the dripline of any tree or stand of trees to be preserved. These protective barriers shall remain so erected throughout all phases of construction.
(v)
The storage of equipment, materials, debris, or fill shall not be allowed within the area protected by the barrier.
(3)
Land development shall minimize impervious cover to promote infiltration of stormwater into the ground consistent with the proposed use or development.
(i)
Grid and modular pavements may be used for any required alley, or other low traffic driveway, unless otherwise approved by the Administrator.
(ii)
Parking areas and driveways shall be designed to minimize impervious surfaces.
(4)
Notwithstanding any other provisions of this Article and Chapter 6, Erosion and Sediment Control, of the King George County Code or exceptions or exemptions thereto, any land disturbing activity equal to or greater than 2,500 square feet, including construction of all single-family houses, septic tanks, and drainfields, shall comply with the requirements of Chapter 6, Erosion and Sediment Control, of the King George County Code.
(5)
All on-site sewage disposal systems not requiring a Virginia Pollutant Discharge Elimination System (VPDES) permit shall:
(i)
Have installed one of the three maintenance provisions:
1.
An inspection port;
2.
An effluent filter; or
3.
A reduced maintenance baffled tank.
(ii)
Have pump-out accomplished for all such systems and provide written proof to the King George County Administrator that the system has been pumped by a licensed septic hauler on a form and in the manner set forth by the Administrator at least once every five years.

In lieu of being required to provide proof of septic tank pump-out every five years, the property owner may submit documentation every five years, certified by an operator or on-site soil evaluator (OSE) licensed or certified under Chapter 23 (§ 54.1-2300 et seq.) of Title 54.1 as being qualified to operate, maintain, or design on-site sewage systems that the septic system has been inspected and is functioning properly, and that the tank does not need to have the effluent pumped out of it.
(6)
A reserve sewage disposal site with a capacity at least equal to that of the primary sewage disposal site shall be provided, in accordance with the King George County On-Site Sewage Disposal Ordinance.
(i)
This requirement shall not apply to any lot or parcel recorded prior to October 1, 1989, if such lot or parcel is not sufficient in capacity to accommodate a reserve sewage disposal site, as determined by the local Health Department.
1.
For any lot or parcel that has recorded adjustments or divisions after October 1, 1989, and resulted in a change to the original footprint of the recorded lot or parcel, the most recent recorded plat shall govern and must comply with 5-2-7 (6), above.
(ii)
Building or construction of any impervious surface shall be prohibited on the area of all sewage disposal sites or on an onsite sewage treatment system which operates under a permit issued by the State Water Control Board, until the structure is served by public sewer.
(7)
Any Chesapeake Bay Preservation Act Land Disturbing Activity that is determined by the County to be grandfathered in accordance with Chapter 5.5, Environment, of the King George County Code shall comply with performance based or technology based technical criteria set forth below:
(i)
Performance-based criteria. For land-disturbing activities, the calculated post-development nonpoint source pollutant runoff load shall be compared to the calculated predevelopment load based upon the average land cover condition or the existing site condition. A BMP shall be located, designed, and maintained to achieve the target pollutant removal efficiencies specified in 9VAC25-870-96 C of the Virginia Stormwater Management Program (VSMP) regulations.
(ii)
Technology-based criteria. For land-disturbing activities, the post-developed stormwater runoff from the impervious cover shall be treated by an appropriate BMP as required by the post-developed condition percent impervious cover as specified in Table 1 of 9VAC25-870-96 C. The selected BMP shall be located, designed, and maintained to perform at the target pollutant removal efficiency specified in 9VAC25-870-96 C of the Virginia Stormwater Management Program (VSMP) regulations or those found in 9VAC25-870-65 of the VSMP regulations.
(8)
Prior to initiating grading or other on-site activities on any portion of a lot or parcel, all wetlands permits required by federal, state, and local laws and regulations shall be obtained and evidence of such submitted to the Administrator, in accordance with Section 5-2-8, Plan of Development, of this Article.
(9)
Land upon which agricultural activities are being conducted, including but not limited to crop production, pasture, and dairy and feedlot operations, or lands otherwise defined as agricultural land by King George County, shall have a soil and water quality conservation assessment conducted that evaluates the effectiveness of existing practices pertaining to soil erosion and sediment control, nutrient management, and management of pesticides, and, where necessary, results in a plan that outlines additional practices needed to ensure that water quality protection is being accomplished consistent with the Act and this chapter.
(i)
Recommendations for additional conservation practices need address only those conservation issues applicable to the tract or field being assessed. Any soil and water quality conservation practices that are recommended as a result of such an assessment and are subsequently implemented with financial assistance from federal or state cost-share programs must be designed, consistent with cost-share practice standards effective in January 1999 in the "Field Office Technical Guide," as amended, of the U.S. Department of Agriculture Natural Resource Conservation Service or the June 2000 edition of the "Virginia Agricultural BMP Manual," as amended, of the Virginia Department of Conservation and Recreation, respectively. Unless otherwise specified in this section, general standards pertaining to the various agricultural conservation practices being assessed shall be as follows:
1.
For erosion and sediment control recommendations, the goal shall be, where feasible, to prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996, as amended, in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service. However, in no case shall erosion exceed the soil loss consistent with an Alternative Conservation System, referred to as an "ACS", as defined in the "Field Office Technical Guide" of the U.S. Department of Agriculture Natural Resource Conservation Service.
2.
For nutrient management, whenever nutrient management plans are developed, the operator or landowner must provide soil test information, consistent with the Virginia Nutrient Management Training and Certification Regulations (4VAC50-85).
3.
For pest chemical control, referrals shall be made to the local cooperative extension agent or an Integrated Pest Management Specialist of the Virginia Cooperative Extension Service. Recommendations shall include copies of applicable information from the "Virginia Pest Management Guide", or other Extension materials related to pest control.
(ii)
A higher priority shall be placed on conducting assessments of agricultural fields and tracts adjacent to RPAs. However, if the landowner or operator of such a tract also has RMA fields or tracts in his operation, the assessment for that landowner or operator may be conducted for all fields or tracts in the operation. When such an expanded assessment is completed, priority must return to RPA fields and tracts.
(iii)
The findings and recommendations of such assessments and any resulting soil and water quality conservation plans will be submitted to the local Soil and Water Conservation District Board which will be the plan-approving authority.
(D)
Buffer Area Requirements. To minimize the adverse effects of human activities on the other components of Resource Protection Areas (RPA), state waters, and aquatic life, a 100-foot buffer area of vegetation that is effective in retarding runoff, preventing erosion, and filtering non-point source pollution from runoff shall be retained if present and established where it does not exist.
(1)
The buffer area shall be located adjacent to and landward of other RPA components and along both sides of any water body with perennial flow. The full buffer area shall be designated as the landward component of the RPA, in accordance with Sections 5-2-1, Applicability, and Section 5-2-8, Plan of Development, of this Article.
(i)
The buffer area shall be designed to follow the length of all RPA components on the site and shall not be designed to be clustered but spread out to achieve a true buffer that prevents erosion.
(ii)
Where feasible, the buffer area shall include flora that is native to King George County.
(2)
Where land uses such as agriculture or silviculture within the area of the buffer cease and the lands are proposed to be converted to other uses, the full 100-foot-wide buffer shall be reestablished. In reestablishing the buffer, management measures shall be undertaken to provide woody vegetation that assures the buffer functions as set forth in this Article.
(3)
When replanting is required to establish a buffer, a combination of trees, groundcover, and shrubs with a demonstrated ability to improve water quality shall meet the intent of the buffer area.
(4)
The 100-foot buffer area shall be deemed to achieve a 75% reduction of sediments and a 40% reduction of nutrients.
(5)
The buffer area shall be maintained to meet the following additional performance standards:
(i)
To maintain the functional value of the buffer area, indigenous vegetation may be removed subject to approval by the Administrator only to provide for reasonable sight lines, access paths, general woodlot management, and best management practices including those that prevent upland erosion and concentrated flows of storm water, as follows:
1.
Trees may be pruned or removed as necessary to provide for sight lines and vistas provided that where removed, they shall be replaced with other vegetation that is equally effective in retarding runoff, preventing erosion, and filtering non-point source pollution from runoff.
2.
Any path shall be constructed to effectively control erosion.
3.
Dead, diseased, or dying trees or shrubbery and noxious weeds (including, but not limited to, Japanese Stiltgrass, Phragmites, Johnson Grass, Kudzu and Multiflora Rose) may be removed and thinning of trees may be allowed, pursuant to sound horticultural practice incorporated into locally adopted standards.
4.
For shoreline erosion control projects, trees and woody vegetation may be removed, necessary control techniques employed, and appropriate vegetation established to protect or stabilize the shoreline in accordance with the best available technical advice and applicable permit conditions or requirements.
(ii)
When the application of the buffer areas would result in the loss of a buildable area on a lot or parcel recorded prior to October 1, 1989, the Administrator may authorize encroachments into the buffer area in accordance with Section 5-2-8, Plan of Development, and the following criteria:
1.
Encroachments into the buffer areas shall be the minimum necessary to achieve a reasonable buildable area for a principal structure and necessary utilities;
2.
Where practicable, a vegetated area that will maximize water quality protection, mitigate the effects of the buffer encroachment, and is at a minimum equal to the area of encroachment into the buffer area shall be established elsewhere on the lot or parcel; and
3.
The encroachment may not extend into the seaward 50 feet of the buffer area.
(iii)
On agricultural lands, the agricultural buffer area shall be managed to prevent concentrated flows of surface water from breaching the buffer area and appropriate measures may be taken to prevent noxious weeds (including, but not limited to, Japanese Stiltgrass, Phragmites, Johnson Grass, Kudzu and Multiflora Rose) from invading the buffer area. Agricultural activities may encroach into the buffer area as follows:
1.
Agricultural activities may encroach into the landward 50 feet of the 100-foot wide buffer area when at least one agricultural best management practice which, in the opinion of the local soil and water conservation district board, addresses the more predominant water quality issue on the adjacent land erosion control or nutrient management is being implemented on the adjacent land, provided that the combination of the undisturbed buffer area and the best management practice achieves water quality protection, pollutant removal, and water resource conservation at least the equivalent of the 100-foot wide buffer area. If nutrient management is identified as the predominant water quality issue, a nutrient management plan, including soil tests, must be developed consistent with the Virginia Nutrient Training and Certification Regulations (4 VAC 5-15) administered by the Virginia Department of Conservation and Recreation.
2.
Agricultural activities may encroach within the landward 75 feet of the 100-foot-wide buffer area when Agricultural Best Management Practices, which address erosion control, nutrient management, and pest chemical control, are being implemented on the adjacent land. The erosion control practices must prevent erosion from exceeding the soil loss tolerance level, referred to as "T," as defined in the "National Soil Survey Handbook" of November 1996 in the "Field Office Technical Guide," as amended, of the U.S. Department of Agriculture Natural Resource Conservation Service. A nutrient management plan, including soil tests, must be developed, consistent with the Virginia Nutrient Management Training and Certification Regulations (4 VAC 5-15) administered by the Virginia Department of Conservation and Recreation. In conjunction with the remaining buffer area, this collection of best management practices shall be presumed to achieve water quality protection at least the equivalent of that provided by the 100-foot-wide buffer area.
3.
The buffer area is not required to be designated adjacent to agricultural drainage ditches if at least one best management practice which, in the opinion of the local Soil and Water Conservation District Board, addresses the more predominant water quality issue on the adjacent land either erosion control or nutrient management is being implemented on the adjacent land.
4.
If specific problems are identified pertaining to agricultural activities which are causing pollution of the nearby water body with perennial flow or violate performance standards pertaining to the vegetated buffer area, the Administrator, in cooperation with Soil and Water Conservation District, shall recommend a compliance schedule to the landowner and require the problems to be corrected consistent with that schedule. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.
5.
In cases where the landowner or his agent or operator has refused assistance from the Soil and Water Conservation District in complying with or documenting compliance with the agricultural requirements of this chapter, the District shall report the noncompliance to the Director of the King George County Department of Community Development. The Director shall require the landowner to correct the problems within a specified period of time not to exceed 18 months from their initial notification of the deficiencies to the landowner. King George County, in cooperation with the District, shall recommend a compliance schedule to the landowner. This schedule shall expedite environmental protection while taking into account the seasons and other temporal considerations so that the probability for successfully implementing the corrective measures is greatest.

This Division is adopted pursuant to the authority granted to localities by the Code of Virginia §15.2-2280, as amended, and may be referred to as the King George County Floodplain Management Overlay District, floodplain overlay, or flood hazard overlay.
These provisions shall apply to all lands within the jurisdiction of King George County and identified as special flood hazard areas (SFHAs) identified by the County or shown on the flood insurance rate map (FIRM) or included in the flood insurance study (FIS) that are provided to the County by the Federal Emergency Management Agency (FEMA).
(A)
No land shall hereafter be developed, and no structure shall be located, relocated, constructed, reconstructed, enlarged, or structurally altered except in full compliance with the terms and provisions of this Division and Article, and any other applicable ordinances and regulations which apply to uses within the jurisdiction of this ordinance.
(B)
The degree of flood protection sought by the provisions of this Division is considered reasonable for regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur on rare occasions. Flood heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This Division does not imply that areas outside the floodplain area or that land uses permitted within such area will be free from flooding or flood damages.
(C)
This Division shall not create liability on the part of King George County or any officer or employee thereof for any flood damages that result from reliance on this Division, or any administrative decision lawfully made there under.
(A)
This Division supersedes any locally adopted flooding regulations currently in effect in flood-prone districts. Any regulations, however, shall remain in full force and effect to the extent that its provisions are more restrictive.
(B)
These regulations are not intended to repeal or abrogate any existing ordinances including subdivisions, zoning ordinances, or building codes. In the event of a conflict between these regulations and any other ordinance, the more restrictive shall govern.
(A)
Any person who fails to comply with any of the requirements or provisions of this Division, or directions of the Administrator, or any other authorized employee of the King George County, shall be subject to the penalties pursuant to the Code of Virginia, and as outlined in the VA Uniform Statewide Building Code (USBC) for building code violations and Article II, Division 4, Enforcement, of the King George County Zoning Ordinance for violations and associated penalties.
(B)
In addition to the above penalties, all other actions are hereby reserved, including an action in equity for the proper enforcement of this Division. The imposition of a fine or penalty for any violation of, or noncompliance with, this Division shall not excuse the violation or noncompliance or permit it to continue; and all such persons shall be required to correct or remedy such violations within a reasonable time. Any structure constructed, reconstructed, enlarged, altered, or relocated in noncompliance with this Division may be declared by the County to be a public nuisance and abatable as such. Flood insurance may be withheld from structures constructed in violation of this Division.
(A)
The Board of Supervisors shall appoint a designee to administer and implement the regulations of this Division, referred to herein as the Administrator. If no appointment is made, the Director of Community Development shall serve as the Administrator. The Administrator may:
(1)
Administer the duties and responsibilities herein.
(2)
Delegate duties and responsibilities set forth in these regulations to qualified technical personnel, plan examiners, inspectors, and other employees.
(3)
Enter into a written agreement or written contract with another community or private sector entity to administer specific provisions of these regulations. Administration of any part of these regulations by another entity shall not relieve the community of its responsibilities pursuant to the participation requirements of the National Flood Insurance Program as set forth in the Code of Federal Regulations at 44 C.F.R. 59.22.
(A)
The duties and responsibilities of the Administrator shall include but are not limited to:
(1)
Review applications for permits to determine whether proposed activities will be located in a SFHA.
(2)
Interpret floodplain boundaries and provide available base flood elevation and flood hazard information.

(10)
Submit to FEMA, or require to be submitted to FEMA, at the applicant's expense, data, and information necessary to maintain FIRMs, including hydrologic and hydraulic engineering analyses prepared by or for King George County, within 6 months after such data and information becomes available if the analysis indicates changes in base flood elevations. The Administrator may submit data via a LOMR. Such a submission is necessary so that upon confirmation of those physical changes affecting flooding conditions, risk premium rates and floodplain management requirements will be based upon current data.
(11)
Maintain and permanently keep records that are necessary for the administration of these regulations, including:
(i)
Copies of FISs, FIRMS (including historic studies and maps and current effective studies and maps), and Letters of Map Change (LOMC); and
(ii)
Documentation supporting issuance and denial of permits, elevation certificates, documentation of the elevation (in relation to the datum on the FIRM) to which structures have been floodproofed, other required design certifications, variances, and records of enforcement actions taken to correct violations of these regulations.
(12)
Enforce the provisions of these regulations, investigate violations, issue notices of violations or stop work orders, and require permit holders to take corrective action.
(13)
Advise the BZA regarding the intent of these regulations and, for each application for a variance, prepare a staff report and recommendation.
(14)
Administer the requirements related to proposed work on existing buildings:
(i)
Make determinations as to whether buildings and structures that are in SFHA that are damaged by any cause have been substantially damaged.
(ii)
Make reasonable efforts to notify owners of substantially damaged structures of the need to obtain a permit to repair, rehabilitate, or reconstruct the structure. Prohibit the repair of a substantially damaged building without a permit, except for temporary emergency protective measures necessary to secure a property or to stabilize a building or structure to prevent additional damage.
(15)
Undertake, as determined appropriate by the Administrator due to the circumstances, other actions, which may include but are not limited to: issuing press releases, public service announcements, and other public information materials related to permit requests and repair of damaged structures; coordinating with other federal, state, and local agencies to assist with substantial damage determinations; providing owners of damaged structures information related to the proper repair of damaged structures in SFHAs and assisting property owners with documentation necessary to file claims for increased cost of compliance coverage under National Flood Insurance Program (NFIP) flood insurance policies.
(16)
Notify FEMA when the corporate boundaries of the King George County have been modified and:
(i)
Provide a map that clearly delineates the new corporate boundaries or the new area for which the authority to regulate pursuant to these regulations has either been assumed or relinquished through annexation; and
(ii)
If the FIRM for any annexed area includes special flood hazard areas that have flood zones that have regulatory requirements that are not set forth in these regulations, prepare amendments to these regulations to adopt the FIRM and appropriate requirements, and submit the amendments to the governing body for adoption; such adoption shall take place at the same time as or prior to the date of annexation and a copy of the amended regulations shall be provided to DCR and FEMA.
(17)
Upon the request of FEMA, complete and submit a report concerning participation in the NFIP, which may request information regarding the number of buildings in the SFHA, number of permits issued for development in the SFHA, and number of variances issued for development in the SFHA.
(18)
It is the duty of the Administrator to consider flood, mudslide, and flood-related erosion hazards, to the extent that they are known, in all official actions relating to land management and use throughout the entire jurisdictional area of the County, whether or not those hazards have been specifically delineated geographically (e.g., via mapping or surveying).
Records of actions associated with administering this Division shall be kept on file and maintained by the Administrator or their designee.
(A)
The Administrator shall make interpretations, where needed, as to the exact location of SFHA, floodplain boundaries, and floodway boundaries. The following shall apply to the use and interpretation of FIRMs and data:
(1)
Where field surveyed topography indicates that adjacent ground elevations:
(i)
Are below the base flood elevation in riverine SFHAs, or are below the 1% storm surge elevation in coastal SFHAs, even in areas not delineated as a SFHA on a FIRM, the area shall be considered as a SFHA and subject to the requirements of these regulations; or
(ii)
Are above the base flood elevation, the area shall be regulated as a SFHA unless the applicant obtains a LOMC that removes the area from the SFHA.
(2)
In FEMA-identified SFHAs where base flood elevation and floodway data have not been identified and in areas where FEMA has not identified SFHAs, any other flood hazard data available from a federal, state, or other source shall be reviewed and reasonably used.
(3)
Base flood elevations and designated floodway boundaries on FIRMs and in FISs shall take precedence over base flood elevations and floodway boundaries by any other sources if such sources show reduced floodway widths and/or lower base flood elevations.
(4)
Other sources of data shall be reasonably used if such sources show increased base flood elevations and/or larger floodway areas than are shown on FIRMs and in FISs.
(5)
If a preliminary FIRM and/or a preliminary FIS has been provided by FEMA:
(i)
Upon the issuance of a Letter of Final Determination (LOFD) by FEMA, the preliminary flood hazard data shall be used and shall replace the flood hazard data previously provided from FEMA for the purposes of administering these regulations.
(ii)
Prior to the issuance of a LOFD by FEMA, the use of preliminary flood hazard data shall be deemed the best available data pursuant to Section 5-3-14 (A)(3)(iii) as defined by this Division and used where no base flood elevations and/or floodway areas are provided on the effective FIRM.
(iii)
Prior to issuance of a LOFD by FEMA, the use of preliminary flood hazard data is permitted where the preliminary base flood elevations or floodway areas exceed the base flood elevations and/or designated floodway widths in existing flood hazard data provided by FEMA. Such preliminary data may be subject to change and/or appeal to FEMA.
(A)
The County floodplain overlay in effect on the date of annexation shall remain in effect and shall be enforced by the municipality for all annexed areas until the municipality adopts and enforces an ordinance which meets the requirements for participation in the NFIP. Municipalities with existing floodplain ordinances shall pass a resolution acknowledging and accepting responsibility for enforcing floodplain ordinance standards prior to annexation of any area containing identified flood hazards. If the FIRM for any annexed area includes SFHAs with flood zones that have regulatory requirements that are not set forth in these regulations, the governing body shall prepare amendments to these regulations to adopt the FIRM and appropriate requirements, and submit the amendments to the governing body for adoption; such adoption shall take place at the same time as or prior to the date of annexation and a copy of the amended regulations shall be provided to DCR Division of Dam Safety and Floodplain Management and FEMA.
(B)
In accordance with the Code of Federal Regulations, Title 44 Subpart (B) Section 59.22(a)(9)(v), all NFIP participating communities must notify the Federal Insurance Administration and optionally the state coordinating office in writing whenever the boundaries of the community have been modified by annexation or the community has otherwise assumed or no longer has authority to adopt and enforce floodplain management regulations for a particular area.
(C)
To ensure that all FIRMs accurately represent the community's boundaries, a copy of a map of the community suitable for reproduction, clearly delineating the new corporate limits or new area for which the community has assumed, or relinquished floodplain management regulatory authority must be included with the notification.
The delineation of the Floodplain Management District may be revised by the King George County Board of Supervisors where natural or man-made changes have occurred and/or where more detailed studies have been conducted or undertaken by the U.S. Army Corps of Engineers or other qualified agency or an individual documents the need for such change. However, prior to any such change, approval must be obtained from FEMA. An approved Letter of Map Revision (LOMR) serves as record of this change.
Initial interpretations of the boundaries of the Floodplain Management Overlay shall be made by the Administrator or designee. Should a dispute arise concerning the boundaries of any of the districts, the BZA shall make the necessary determination in accordance with Article III, Permits and Applications, of this Ordinance. The person questioning or contesting the location of the district boundary shall be given a reasonable opportunity to present their case to the BZA and to submit his own technical evidence if they so desire.
(A)
When development in the floodplain will cause or causes a change in the base flood elevation, the applicant, including state agencies, must notify FEMA by applying for a Conditional Letter of Map Revision (CLOMR) or a LOMR. Examples include:
(1)
Any development that causes a rise in the base flood elevations within the floodway.
(2)
Any development occurring in zone AE without a designated floodway, which will cause a rise of more than one foot in the base flood elevation.
(3)
Alteration or relocation of a stream (including but not limited to installing culverts and bridges) 44 CFR 65.3 and 65.6(a)(12).
(A)
Basis of flood hazard zones. The various flood hazard zones shall include special flood hazard areas (SFHA). The basis for the delineation of these zones shall be the FIS and the FIRM for King George County, Virginia, and incorporated areas prepared by FEMA, Federal Insurance Administration, dated December 2, 2021, and any subsequent revisions or amendments thereto.
(1)
King George County may identify and regulate local flood hazard or ponding areas that are not delineated on the FIRM. These areas may be delineated on a "Local Flood Hazard Map" using best available topographic data and locally derived information such as flood of record, historic high-water marks, or approximated study methodologies.
(2)
The boundaries of the SFHA and flood hazard zones are established as shown on the FIRM which is declared to be a part of this Division, and which shall be kept on file at the King George County Community Development offices.
(3)
The flood hazard zones described below shall constitute the Floodplain Management Overlay District. It shall be an overlay to the existing underlying zoning districts as shown on the official zoning ordinance map, and as such, the provisions for the Floodplain Management Overlay District shall serve as a supplement to the underlying district provisions.
(i)
AE Zone. Those areas with at least a 1% annual chance of being flooded. Also includes the "Coastal A Zone," which are areas that are subject to wave heights between 1.5 feet and 3 feet. AE zones have two categories, defined below:
1.
Category 1 areas on the FIRM accompanying the FIS are delineated for purposes of this Division using the criteria that certain areas within the floodplain must be capable of carrying the water of the base flood without increasing the water surface elevation of that flood more than one foot at any point. These areas included in this district are specifically defined in Table 2 of the King George County FIS and shown on the accompanying FIRM on file with the King George County Community Development offices. Category 1 areas shall be those areas for which one-percent annual chance flood elevations have been provided and the floodway has been delineated.
2.
Category 2 areas on the FIRM accompanying the FIS shall be those areas for which one-percent annual chance flood elevations have been provided and the floodway has not been delineated.
(ii)
AH Zone. Those areas on the FIRM accompanying the FIS with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones; for the purposes of elevation and construction standards of Section 5-3-17, the AH Zone shall be considered a Category 2 area.
(iii)
A Zone. Those areas known as the Approximated Floodplain Areas, for which no detailed flood profiles or elevations are provided, but the one percent annual chance floodplain boundary has been approximated. For these areas, the base flood elevations and floodway information from Federal, State, and other acceptable sources shall be used, when available [44 CFR 60.3(b)]. Where the specific one percent annual chance flood elevation cannot be determined for this area using other sources of data, such as the U.S. Army Corps of Engineers Floodplain Information Reports, U.S. Geological Survey Flood-Prone Quadrangles, etc., then the applicant for the proposed use, development and/or activity shall determine this base flood elevation. The elevation shall be determined by using the elevation of a point on the boundary of the identified floodplain area which is nearest the construction site. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by the Administrator.
(iv)
AO Zone. Those areas of shallow flooding identified as AO on the FIRM.
(v)
VE or V Zones. Those areas that are known as Coastal High Hazard Areas, extending from offshore to the inland limit of a primary frontal dune along an open coast or other areas subject to high velocity waves.
(vi)
X Zone. Other flood districts shall be those areas identified as Zone X on the maps accompanying the flood insurance study. This zone includes areas of 0.2% annual chance flood or areas of 1% annual chance flood with average depths of less than one foot or with drainage areas less than one square mile.
(4)
Where the specific base flood elevation cannot be determined for this area using other sources of data, such as the U.S. Army Corps of Engineers Flood Plain Information Reports, U.S. Geological Survey Flood-prone Quadrangles, etc., then the applicant for the proposed use, development and/or activity shall determine this elevation in accordance with hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by King George County.
(A)
Permit requirement.
(1)
All uses, activities and, development occurring within the Floodplain Management Overlay shall be undertaken only upon the issuance of a permit. Such development shall be undertaken only in strict compliance with the provisions of this Division and with all other applicable codes and ordinances, as amended, such as the VA USBC and the King George County Zoning and Subdivision Ordinance. Prior to the issuance of any such permit, the Administrator shall require all applications to include compliance with all applicable state and federal laws and shall review all sites to assure they are reasonably safe from flooding. Under no circumstances shall any use, activity and/or development adversely affect the capacity of the channels or floodways or any watercourse, drainage ditch or any other drainage facility or system.
(2)
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 U.S. Army Corps of Engineers, the Virginia Marine Resources Commission, and the Virginia State Water Control Board. Further notification of the proposal shall be given to all adjacent jurisdictions, the Division of Dam Safety and Flood Plain Management at the Department of Conservation and Recreation and the Federal Emergency Management Agency.
(B)
Site Plans and Permit Applications.
(1)
All applications for development in the floodplain areas and all building permits issued for the floodplain shall incorporate the following information:

(iv)
Topographic information showing existing and proposed ground elevations.
(C)
Standards for Subdivision Proposals. All subdivision proposals shall:
(1)
Any subdivision proposal or other proposed development (including proposals for manufactured home parks and subdivisions) that exceed 50 lots or 5 acres, whichever is less, in an area where BFE data is not available or the SFHA has not been delineated, shall include data using detailed methodologies, including a hydraulic and hydrologic analysis, comparable to those contained in a FIS. Once identified, those areas shall be subject to the requirements of this Division.
(2)
Have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage;
(3)
Have adequate drainage provided to reduce exposure to flood hazards.
In all identified flood hazard areas where base flood elevations have been provided in the FIS or generated by a certified professional in accordance with Section 5-3-14 (A)(3), above, the following provisions shall apply:

(1)
Within any AE Category 1 area, no encroachments, including fill, new construction, substantial improvements, or other development shall be permitted unless it has been demonstrated through hydrologic and hydraulic analysis performed in accordance with standard engineering practice that the proposed encroachment will not result in any increase in flood levels within the community during the occurrence of the base flood discharge. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by the Administrator.
(i)
Development activities which increase the water surface elevation of the base flood may be allowed, provided that the applicant first applies—with King George County's endorsement—for a Conditional Letter of Map Revision (CLOMR) and receives the approval of FEMA.
(ii)
If subsection (i), above, is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Section 5-3-17.
(2)
Within any AE Category 2 or AH area, until a regulatory floodway is designated, no new construction, substantial improvements, or other development (including fill) shall be permitted within the areas of special flood hazard, designated as Zones AE or AH on the FIRM, unless it is demonstrated 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 one foot at any point within the County.
(3)
Development activities in Zones AE or AH on King George County's FIRM which increase the water surface elevation of the base flood by more than one foot may be allowed, provided that the applicant first applies-with the County's endorsement-for a CLOMR and receives the approval of FEMA.
(C)

For development proposed in the A Zone (approximate floodplain) the applicant must use technical methods that correctly reflect currently accepted practices, such as point on boundary, high water marks, or detailed methodologies hydrologic and hydraulic analyses. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by the Floodplain Administrator.
(2)
The Floodplain Administrator reserves the right to require a hydrologic and hydraulic analysis for any development. When such base flood elevation data is utilized, the lowest floor shall be elevated to or above the base flood level plus twelve (12) inches.
(3)
During the permitting process, the Floodplain Administrator shall obtain:
(i)
The elevation of the lowest floor (in relation to mean sea level), including the basement, of all new and substantially improved structures; and,
(ii)
If the structure has been floodproofed in accordance with the requirements of this article, the elevation (in relation to mean sea level) to which the structure has been floodproofed.
(D)
AO Zone.
(1)
All new construction and substantial improvements of residential structures shall have the lowest floor, including basement, elevated to or above the flood depth specified on the FIRM, above the highest adjacent grade at least as high as the depth number specified in feet on the FIRM. If no flood depth number is specified, the lowest floor, including basement, shall be elevated no less than two feet above the highest adjacent grade.
(2)
All new construction and substantial improvements of non-residential structures shall:
(i)
Have the lowest floor, including basement, elevated to or above the flood depth specified on the FIRM, above the highest adjacent grade at least as high as the depth number specified in feet on the FIRM. If no flood depth number is specified, the lowest floor, including basement, shall be elevated at least two feet above the highest adjacent grade; or
(ii)
Together with attendant utility and sanitary facilities be completely floodproofed to the specified flood level so that any space below that level is 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)
Adequate drainage paths around structures on slopes shall be provided to guide floodwaters around and away from proposed structures.
(E)
V and VE Zones.
(1)
Within V and VE Zones, which are areas of coastal high hazard that have special flood hazards associated with wave wash, the following additional provisions shall apply:
(i)
Within V-Zones on the Flood Insurance Rate Maps, the Administrator shall obtain the elevation (in relation to mean sea level) of the bottom of the lowest horizontal structural member of the lowest floor (excluding pilings and columns) of all new and substantially improved structures, and whether or not such structures contain a basement. The Administrator shall maintain record of all such information.
(ii)
All new construction shall be located landward of the reach of mean high tide.
(iii)
There shall be no fill used as structural support. When non-structural fill is proposed, appropriate engineering analyses shall be conducted to evaluate the impacts of the fill prior to issuance of a permit.
(iv)
There shall be no alteration of sand dunes which would increase potential flood damage.
(v)
All new construction and substantial improvements, including manufactured homes, shall be elevated on pilings and columns so that:
1.
The bottom of the lowest horizontal structural member of the lowest floor (excluding pilings and columns) elevated to or above the base flood level plus 12 inches.
2.
The pile or column foundation and structure attached thereto must be anchored to resist floatation, collapse, and lateral movement due to the effects of wind and water loads acting simultaneously on all building components. Wind and water loading values shall each have a 1% chance of being equaled or exceeded in any given year (one-percent annual chance).
(vi)
A registered professional engineer or architect shall develop or review the structural design and methods of construction and shall certify that design and methods of construction to be used are in accordance with accepted standards of practice for meeting the provisions of this Section.
(vii)
Provide that all new construction and substantial improvements, within Zones VE and V on the community's FIRM, have the space below the lowest floor either free of obstruction or constructed with non-supporting breakaway walls, open wood lattice-work, or insect screening intended to collapse under wind and water loads without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system. For the purpose of this section, a breakaway wall shall have a design safe loading resistance of not less than 10 and no more than 20 pounds per square foot. Use of breakaway walls which exceed a design safe loading resistance of 20 pounds per square foot, either by design or when so required by local or State codes, may be permitted only if a registered professional engineer or architect certifies that the designs proposed meet the following conditions:
1.
Breakaway wall collapse shall result from a water load less than that which would occur during the base flood; and
2.
The elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components, structural and non-structural. Water loading values used shall be those associated with the base flood. Wind loading values used shall be those required by applicable State or local building standards.
(viii)
Enclosed space below the lowest floor shall be usable solely for parking of vehicles, building access or storage and shall not be partitioned into multiple rooms, temperature-controlled, or used for human habitation.
(F)
Residential Construction.

Nonresidential Construction.
(1)
New construction or substantial improvement of any commercial, industrial, or nonresidential building shall have the lowest floor, including basement, elevated to or above the base flood level plus 12 inches.
(2)
Non-residential buildings located in all AE and AH zones may be floodproofed in lieu of being elevated provided that all areas of the building components below the elevation corresponding to the base flood elevation plus one foot 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. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification, including the specific elevation (in relation to mean sea level) to which such structures are floodproofed, shall be maintained by the Administrator.
(H)
Space Below the Lowest Floor.
(1)
In zones A, AE, AH, and AO, fully enclosed areas of new construction or substantially improved structures, which are below the regulatory flood protection elevation shall:
(i)
Not be designed or used for human habitation, but shall be used solely 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);
(ii)
Be constructed entirely of flood resistant materials below the regulatory flood protection elevation; and
(iii)
Include measures to automatically equalize hydrostatic flood forces on walls by allowing for the entry and exit of floodwaters. To meet this requirement, the openings must either be certified by a professional engineer or architect or meet the following minimum design criteria:
1.
Provide a minimum of two openings on different sides of each enclosed area subject to flooding.
2.
The total net area of all openings must be at least 1 square inch for each square foot of enclosed area subject to flooding.
3.
If a building has more than one enclosed area, each area must have openings to allow floodwaters to automatically enter and exit.
4.
The bottom of all required openings shall be no higher than 1 foot above the adjacent grade.
5.
Openings may be equipped with screens, louvers, or other opening coverings or devices, provided they permit the automatic flow of floodwaters in both directions.
6.
Foundation enclosures made of flexible skirting are not considered enclosures for regulatory purposes, and, therefore, do not require openings. Masonry or wood underpinning, regardless of structural status, is considered an enclosure and requires openings as outlined above.
(I)
Accessory Structures.
(1)
Accessory structures in the SFHA shall comply with the elevation requirements and other requirements of Section 5-3-16 or, if not elevated or dry floodproofed, shall:
(i)
Not be used for human habitation;
(ii)

Table V-2. MCAOD Noise Sensitive Uses
(B)
Disclosures.
(1)
Property Buyer/Renter Disclosure. To make buyers and renters of any property within the MCAOD aware of its sensitive location, the owner, realtor, seller, broker, or agent of the property for sale is responsible for and must provide the buyer/renter with a disclosure statement stating the following:
(i)
The residence, structure, or property offered for purchase or rent is located in the MCAOD;
(ii)
The specific subarea that the residence, structure, or property is located;
(iii)
The residence, structure, or property is near or next to a military facility and noise decibels, vibration levels, and potential frequency interference could be a concern as military operations are conducted at various times throughout the day;
(iv)
Single noise events impacting the residence, structure, or property may result in significantly higher noise levels than the average level(s) in any of the Noise Zones listed within the Disclosure document. Noise Zones are subject to change, and for this reason, it should not be assumed that the property will remain in the same Noise Zone.
(v)
The residence or structure on the property was built prior to enacting the MCAOD regulations and therefore, may not necessarily have been built to withstand high noise decibels, vibration levels, or frequency interference; and
(vi)
If in fact, the residence has been built to reduce noise levels indoors, state the noise level reduction (NLR) for which the building was designed.
