PRESERVATION AREA OVERLAY DISTRICT
This subchapter shall be known and referenced as the "Chesapeake Bay Preservation Area Overlay District" of the town.
(Ord. passed 3-10-2005; Ord. passed 9-12-2013)
(A)
(1)
The Chesapeake Bay and its tributaries constitute one of the most important and productive estuarine systems in the world, providing economic and social benefits to the citizens of the town and the state.
(2)
The health of the Bay is vital to maintaining the town's economy and the welfare of its citizens.
(B)
(1)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including, non-point source pollution from land uses and development.
(2)
Existing high quality waters are worthy of protection from degradation to guard against further pollution.
(3)
Certain lands that are proximate to shorelines have intrinsic water quality value due to the ecological and biological processed they perform.
(4)
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 and shoreline erosion control.
(5)
These lands together, designated by the town council as Chesapeake Bay Preservation Areas ("CBPAs"), shall be protected from destruction and damage in order to protect the quality of water in the Bay and consequently the quality of life in the town and the state.
(Ord. passed 3-10-2005; Ord. passed 9-12-2013)
(A)
(1)
This subchapter is enacted to implement the requirements of Code of Virginia, §§ 62.1-44.15:67 et seq. (the Chesapeake Bay Preservation Act: sometimes hereinafter referred to as the "Act").
(2)
The intent of town council and the purpose of the Overlay District is to support the goals of the Act and the town's Comprehensive Plan by protecting and improving the quality of the Chesapeake's Bay's waters, its tributaries, buffer areas and other sensitive environmental lands by minimizing the potential adverse effects of human activity upon these areas by:
(a)
Protecting existing high quality state waters;
(b)
Restoring 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;
(c)
Safeguarding the clean waters of the state from pollution;
(d)
Preventing any increase in pollution;
(e)
Reducing existing pollution; and
(f)
Promoting water resource conservation in order to provide for the health, safety and welfare of the present and future citizens of the town.
(B)
This district shall be in addition to and shall overlay all other zoning districts where they are applied so that any parcel of land lying in the Chesapeake Bay Preservation Area Overlay District shall also lie in one or more of the other zoning districts provided for by the zoning regulations. Unless otherwise stated in the Overlay District, the review and approval procedures provided for, hereinafter shall be followed in reviewing and approving development, redevelopment and uses governed by the subchapter.
(C)
This subchapter is enacted under the authority of Code of Virginia, §§ 62.1-44.15:52 et seq. (the Chesapeake Bay Preservation Act) and Code of Virginia, § 15.2-2283. Code of Virginia, § 15.2-2283 states that zoning ordinances may "also include reasonable provisions, not inconsistent with applicable state water quality standards, to protect surface water and groundwater as defined in Code of Virginia, § 62.1-255."

(Ord. passed 3-10-2005; Ord. passed 9-12-2013)
(A)
Purpose and intent.
(1)
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.
(2)
The purpose and intent of these requirements are also to implement the following objectives: prevent a net increase in non-profit source pollution from new development; achieve a ten percent reduction in non-point source pollution from redevelopment; and achieve a 40 percent reduction in non-point source pollution from agricultural uses.
(B)
General performance standards for development and redevelopment. All development and redevelopment in the CBPAs exceeding 2,500 square feet of land disturbance shall be subject to a plan of development process in accordance with the requirements of § 154.155 and shall also be subject to the applicable provisions of the town subdivision ordinance and its zoning regulations, the erosion and sediment control ordinance of the county and the county wetlands ordinance.
(1)
Land disturbance shall be limited to the area necessary to provide for proposed use or development.
(a)
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.
(b)
No more land shall be disturbed than is necessary to provide for proposed use or development. The construction footprint shall not exceed the limits for such as designated by the zoning district of the lot or parcel.
(c)
Ingress and egress during construction shall be limited to one access point, unless otherwise approved by the zoning administrator.
(2)
Indigenous vegetation shall be preserved to the maximum extent practical consistent with the use or development proposed and in accordance with the Virginia Erosion and Sediment Control Handbook.
(a)
Existing trees over six inches in diameter at breast height (DBH) shall be preserved outside the construction footprint. Diseased trees or trees weakened by age, storm, fire or other injury may be removed when approved by the zoning administrator.
(b)
Clearing shall be allowed only to provide necessary access, positive site drainage, water quality BMPs and the installation of utilities, as approved by the zoning administrator.
(c)
Prior to cleaning or grading, suitable protective barriers, such as safety fencing, shall be erected five feet 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. 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.
(a)
Gravel, stone, grid or modular pavements or other surfaces as approved by the zoning administrator that promote infiltration, shall be used for any required parking area, alley or other low traffic driveway, unless otherwise approved by the zoning administrator.
(b)
Parking space size shall be 162 square feet. Parking space width shall be nine feet; parking space length shall be 18 feet. Two-way drives shall be a minimum of 22 feet in width.
(4)
Notwithstanding any other provisions of this subchapter or exceptions or exemptions thereto, any land disturbing activity exceeding 2,500 square feet, including construction of any single-family houses, septic tanks and drainfields, shall comply with the requirements of the county erosion and sediment control ordinance.
(5)
(a)
All on-site sewage disposal systems not requiring a VPDES permit shall be pumped out a least once every five years, in accordance with the provisions of the County Health Code.
(b)
In lieu of pump-out, one of the following alternatives way be used:
1.
In the outflow of the pipe a plastic filter may be installed on the septic tank as long as the filter satisfies the standards established in the sewage handling and disposal regulations under 12 VAC §§ 5-610 et seq. as administered by the State Department of Health; or
2.
An owner of on-site sewage treatment system may submit, every five years, documentation that the system has been inspected by a certified sewage handler permitted by the state department of health and that such system is functioning properly and does not need to be pumped out.
(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 County Health Code. 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. Building or construction of any impervious surface shall be prohibited on the area of all sewage disposal sites or on an on-site sewage treatment system which operates under a permit issued by the state water control board, until the structure is served by the public sewer.
(7)
For any development or redevelopment, stormwater runoff shall be controlled by the use of best management practices that are consistent with the water quality provisions of the Virginia Stormwater Management Regulations (4 VAC §§ 62.1-44.15:24 et seq.) and that achieve the following:
(a)
For development, the post-development non-point source pollution runoff load shall not exceed the pre-development load, based on the calculated average land cover for Virginia Chesapeake Bay watershed;
(b)
Best management practices for stormwater runoff quality control, provided the following provisions are satisfied:
1.
In no case may the post-development non-point source pollution runoff load exceed the pre-development load;
2.
Runoff pollution loads must have been calculated and the BMPs selected for the expressed purpose of controlling non-point source pollution;
3.
If best management practices are structural, evidence shall be provided that facilities are currently in good working order and performing at the design levels of service. The zoning administrator may require a review of both the original structural design and maintenance plans to verify this provision. A new maintenance agreement may be required to ensure compliance with this subchapter; and
4.
For redevelopment, both the pre-and post-development loadings shall be calculated by the same procedures. However, where the design data is available, the original post-development non-point source pollution loadings can be substituted for the existing development loadings.
(c)
For single-family dwellings on lots of one acre or greater in size, stormwater runoff calculations are not required, provided the post development impervious coverage for all structures, buildings and other impervious surfaces does not exceed 16 percent of the area.
(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 zoning administrator in accordance with § 154.149, site plans and the town subdivision ordinance.
(9)
Land upon which agricultural activities are being conducted, including, but not limited to, crop production, pasture and dairy and feed operations, or lands otherwise defined as agricultural land by the local government, 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 subchapter.
(C)
Buffer area requirements.
(1)
To minimize the adverse effects of human activities on the other components of resource protection areas, state waters and aquatic life, a 100-foot wide 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.
(2)
The buffer area shall be located adjacent to and landward of other RPA components and along both sides of any with perennial flow. The full 100-foot wide buffer area shall be designated as the landward component of the RPA.
(3)
The 100-foot wide buffer area shall be the landward component of the resource protection area as set forth in 9 VAC § 25-830-80(B)(5). Notwithstanding permitted uses, encroachments and vegetation clearing, as set forth in this section, the 100-foot wide buffer area is not reduced in width. The 100-foot buffer area shall be deemed to achieve a 75 percent reduction of sediments and a 40 percent reduction of nutrients.
(4)
The buffer area shall be maintained to meet the following additional performance standards.
(a)
In order to maintain the functional value of the buffer area, indigenous vegetation may be removed only to provide for reasonable sight lines, access paths, general woodlot management and best management practices, including those that prevent upland erosion when authorized by the zoning administrator, on a case-by-case basis, upon presentation of documentation that the RPA buffer will continue to function in a manner that protects water quality. Such vegetation shall be replaced with other vegetation that is equally effective in retarding runoff, preventing erosion and filtering non-point source pollution from runoff. The following guidelines shall be observed:
1.
Trees may be pruned only as necessary to provide for sight lines and vistas;
2.
Any path shall be constructed and surfaced so as to effectively control erosion;
3.
Dead, diseased or dying trees or shrubbery and noxious weeds (such as Johnson grass, kudzu and multiflora rose) may be removed and thinning of trees may be allowed pursuant to sound horticultural practices incorporated into the town's regulations and in accordance with adopted standards and approved practices; and
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 subject to the issuance of all required permits.
(b)
When the application of the buffer area would result in the loss of a buildable area on a lot or parcel recorded prior to October 1, 1989, encroachments into the buffer area may be allowed through an administrative process before the town planning commission, in accordance with the following criteria:
1.
Encroachments into the buffer area shall be the minimum necessary to achieve a reasonable buildable area for a principle structure and necessary utilities;
2.
Where practical, a vegetated area that will maximize water quality protection, mitigate the effects of the buffer encroachment, and is equal to the area of encroachment into the buffer area shall be established elsewhere on a lot or parcel; and
3.
In no case shall the encroachment extend into the seaward 50 feet of the buffer area.
(c)
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 (such as Johnson grass, kudzu and multiflora rose) from invading the buffer area. Agricultural activities may encroach into the buffer areas 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 Northern Neck 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 test, must be developed consistent with the Virginia Nutrient Management Training and Certification Regulations (4 VAC §§ 50-85 et seq.) administered by the State 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" of the United States Department of Agriculture Natural Resource Conservation Service. A nutrient management plan, including soil test, must be developed consistent with the Virginia Nutrient Management Training and Certification Regulation (4 VAC §§ 5-15 et seq.) 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 for agricultural drainage ditches if the adjacent agricultural land has in place best management practices, at least one best management practice as considered by the Northern Neck Soil and Water Conservation District to address the more predominant water quality issue on the adjacent land, i.e., either erosion control or nutrient management.
(d)
When agricultural or silvicultural uses within the buffer area cease, and the lands are proposed to be converted to other uses, the full 100-foot wide buffer area shall be reestablished. In reestablishing the buffer, management measures shall be undertaken to provide woody vegetation that assures the buffer functions are maintained or established.

(2)
There shall be two levels of water quality impact assessments; a minor assessment and a major assessment.
(C)
Minor water quality impact assessment.
(1)
A minor water quality impact assessment pertains only to land disturbance, development or redevelopment within the CBPAs that causes no more than 5,000 square feet of land disturbance and proposes to encroach into the landward 50 feet of the 100-foot buffer area. A minor assessment must demonstrate through acceptable calculations that the undisturbed buffer area together with necessary best management practices will result in removal of no less than 75 percent of sediments and 40 percent of nutrients from post-development stormwater runoff and that will retard runoff, prevent erosion and filter non-point source pollution and so achieve the equivalent of the full undisturbed 100-foot wide buffer area.
(2)
A minor assessment shall include a site drawing to scale that shows the following:
(a)
Location of the components of the RPA, on site or within a 100-foot wide area abutting the site, including the 100-foot wide buffer area and any water body with perennial flow:
(b)
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;
(c)
Type and location of proposed best management practices to mitigate the proposed encroachment; and
(d)
Location of existing vegetation onsite, including the number and type of trees and other vegetation to be removed in the buffer to accommodate the encroachment or modification and a revegetation plan that supplements the existing buffer vegetation in a manner that provides for pollutant removal, erosion and runoff control.
(D)
Major water quality impact assessment.
(1)
A major water quality impact assessment shall be required for any land disturbance development, or redevelopment that:
(a)
Exceeds 5,000 square fee of land disturbance within the CBPAs and proposes to encroach into the landward 50 feet of the 100-foot wide buffer area;
(b)
Proposes to disturb any portion of the seaward 50 feet of the 100-foot wide buffer area or any other component of an RPA; or
(c)
Is located solely in an RMA and is deemed necessary by the zoning administrator.
(2)
The information required in this section shall be considered a minimum, unless the zoning administrator determines that some of the elements are unnecessary due to the scope and nature of the proposed use and development of land.

(A)
(1)
The Chesapeake Bay and its tributaries constitute one of the most important and productive estuarine systems in the world, providing economic and social benefits to the citizens of the town and the state.
(2)
The health of the Bay is vital to maintaining the town's economy and the welfare of its citizens.
(B)
(1)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including, non-point source pollution from land uses and development.
(2)
Existing high quality waters are worthy of protection from degradation to guard against further pollution.
(3)
Certain lands that are proximate to shorelines have intrinsic water quality value due to the ecological and biological processed they perform.
(4)
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 and shoreline erosion control.
(5)
These lands together, designated by the town council as Chesapeake Bay Preservation Areas ("CBPAs"), shall be protected from destruction and damage in order to protect the quality of water in the Bay and consequently the quality of life in the town and the state.
(Ord. passed 3-10-2005; Ord. passed 9-12-2013)
(A)
(1)

(Ord. passed 3-10-2005; Ord. passed 9-12-2013)
(A)
Purpose and intent.
(1)
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.
(2)
The purpose and intent of these requirements are also to implement the following objectives: prevent a net increase in non-profit source pollution from new development; achieve a ten percent reduction in non-point source pollution from redevelopment; and achieve a 40 percent reduction in non-point source pollution from agricultural uses.
(B)
General performance standards for development and redevelopment. All development and redevelopment in the CBPAs exceeding 2,500 square feet of land disturbance shall be subject to a plan of development process in accordance with the requirements of § 154.155 and shall also be subject to the applicable provisions of the town subdivision ordinance and its zoning regulations, the erosion and sediment control ordinance of the county and the county wetlands ordinance.
(1)
Land disturbance shall be limited to the area necessary to provide for proposed use or development.
(a)
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.
(b)
No more land shall be disturbed than is necessary to provide for proposed use or development. The construction footprint shall not exceed the limits for such as designated by the zoning district of the lot or parcel.
(c)
Ingress and egress during construction shall be limited to one access point, unless otherwise approved by the zoning administrator.
(2)
Indigenous vegetation shall be preserved to the maximum extent practical consistent with the use or development proposed and in accordance with the Virginia Erosion and Sediment Control Handbook.
(a)
Existing trees over six inches in diameter at breast height (DBH) shall be preserved outside the construction footprint. Diseased trees or trees weakened by age, storm, fire or other injury may be removed when approved by the zoning administrator.
(b)
Clearing shall be allowed only to provide necessary access, positive site drainage, water quality BMPs and the installation of utilities, as approved by the zoning administrator.
(c)
Prior to cleaning or grading, suitable protective barriers, such as safety fencing, shall be erected five feet 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. 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.
(a)
Gravel, stone, grid or modular pavements or other surfaces as approved by the zoning administrator that promote infiltration, shall be used for any required parking area, alley or other low traffic driveway, unless otherwise approved by the zoning administrator.
(b)
Parking space size shall be 162 square feet. Parking space width shall be nine feet; parking space length shall be 18 feet. Two-way drives shall be a minimum of 22 feet in width.
(4)
Notwithstanding any other provisions of this subchapter or exceptions or exemptions thereto, any land disturbing activity exceeding 2,500 square feet, including construction of any single-family houses, septic tanks and drainfields, shall comply with the requirements of the county erosion and sediment control ordinance.
(5)
(a)
All on-site sewage disposal systems not requiring a VPDES permit shall be pumped out a least once every five years, in accordance with the provisions of the County Health Code.
(b)
In lieu of pump-out, one of the following alternatives way be used:
1.
In the outflow of the pipe a plastic filter may be installed on the septic tank as long as the filter satisfies the standards established in the sewage handling and disposal regulations under 12 VAC §§ 5-610 et seq. as administered by the State Department of Health; or
2.
An owner of on-site sewage treatment system may submit, every five years, documentation that the system has been inspected by a certified sewage handler permitted by the state department of health and that such system is functioning properly and does not need to be pumped out.
(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 County Health Code. 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. Building or construction of any impervious surface shall be prohibited on the area of all sewage disposal sites or on an on-site sewage treatment system which operates under a permit issued by the state water control board, until the structure is served by the public sewer.
(7)
For any development or redevelopment, stormwater runoff shall be controlled by the use of best management practices that are consistent with the water quality provisions of the Virginia Stormwater Management Regulations (4 VAC §§ 62.1-44.15:24 et seq.) and that achieve the following:
(a)
For development, the post-development non-point source pollution runoff load shall not exceed the pre-development load, based on the calculated average land cover for Virginia Chesapeake Bay watershed;
(b)
Best management practices for stormwater runoff quality control, provided the following provisions are satisfied:
1.
In no case may the post-development non-point source pollution runoff load exceed the pre-development load;
2.
Runoff pollution loads must have been calculated and the BMPs selected for the expressed purpose of controlling non-point source pollution;
3.
If best management practices are structural, evidence shall be provided that facilities are currently in good working order and performing at the design levels of service. The zoning administrator may require a review of both the original structural design and maintenance plans to verify this provision. A new maintenance agreement may be required to ensure compliance with this subchapter; and
4.
For redevelopment, both the pre-and post-development loadings shall be calculated by the same procedures. However, where the design data is available, the original post-development non-point source pollution loadings can be substituted for the existing development loadings.
(c)
For single-family dwellings on lots of one acre or greater in size, stormwater runoff calculations are not required, provided the post development impervious coverage for all structures, buildings and other impervious surfaces does not exceed 16 percent of the area.
(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 zoning administrator in accordance with § 154.149, site plans and the town subdivision ordinance.
(9)
Land upon which agricultural activities are being conducted, including, but not limited to, crop production, pasture and dairy and feed operations, or lands otherwise defined as agricultural land by the local government, 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 subchapter.
(C)
Buffer area requirements.
(1)
To minimize the adverse effects of human activities on the other components of resource protection areas, state waters and aquatic life, a 100-foot wide 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.
(2)
The buffer area shall be located adjacent to and landward of other RPA components and along both sides of any with perennial flow. The full 100-foot wide buffer area shall be designated as the landward component of the RPA.
(3)
The 100-foot wide buffer area shall be the landward component of the resource protection area as set forth in 9 VAC § 25-830-80(B)(5). Notwithstanding permitted uses, encroachments and vegetation clearing, as set forth in this section, the 100-foot wide buffer area is not reduced in width. The 100-foot buffer area shall be deemed to achieve a 75 percent reduction of sediments and a 40 percent reduction of nutrients.
(4)
The buffer area shall be maintained to meet the following additional performance standards.
(a)
In order to maintain the functional value of the buffer area, indigenous vegetation may be removed only to provide for reasonable sight lines, access paths, general woodlot management and best management practices, including those that prevent upland erosion when authorized by the zoning administrator, on a case-by-case basis, upon presentation of documentation that the RPA buffer will continue to function in a manner that protects water quality. Such vegetation shall be replaced with other vegetation that is equally effective in retarding runoff, preventing erosion and filtering non-point source pollution from runoff. The following guidelines shall be observed:
1.
Trees may be pruned only as necessary to provide for sight lines and vistas;
2.
Any path shall be constructed and surfaced so as to effectively control erosion;
3.
Dead, diseased or dying trees or shrubbery and noxious weeds (such as Johnson grass, kudzu and multiflora rose) may be removed and thinning of trees may be allowed pursuant to sound horticultural practices incorporated into the town's regulations and in accordance with adopted standards and approved practices; and
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 subject to the issuance of all required permits.
(b)
When the application of the buffer area would result in the loss of a buildable area on a lot or parcel recorded prior to October 1, 1989, encroachments into the buffer area may be allowed through an administrative process before the town planning commission, in accordance with the following criteria:
1.
Encroachments into the buffer area shall be the minimum necessary to achieve a reasonable buildable area for a principle structure and necessary utilities;
2.
Where practical, a vegetated area that will maximize water quality protection, mitigate the effects of the buffer encroachment, and is equal to the area of encroachment into the buffer area shall be established elsewhere on a lot or parcel; and
3.
In no case shall the encroachment extend into the seaward 50 feet of the buffer area.
(c)
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 (such as Johnson grass, kudzu and multiflora rose) from invading the buffer area. Agricultural activities may encroach into the buffer areas 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 Northern Neck 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 test, must be developed consistent with the Virginia Nutrient Management Training and Certification Regulations (4 VAC §§ 50-85 et seq.) administered by the State 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" of the United States Department of Agriculture Natural Resource Conservation Service. A nutrient management plan, including soil test, must be developed consistent with the Virginia Nutrient Management Training and Certification Regulation (4 VAC §§ 5-15 et seq.) 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 for agricultural drainage ditches if the adjacent agricultural land has in place best management practices, at least one best management practice as considered by the Northern Neck Soil and Water Conservation District to address the more predominant water quality issue on the adjacent land, i.e., either erosion control or nutrient management.
(d)
When agricultural or silvicultural uses within the buffer area cease, and the lands are proposed to be converted to other uses, the full 100-foot wide buffer area shall be reestablished. In reestablishing the buffer, management measures shall be undertaken to provide woody vegetation that assures the buffer functions are maintained or established.

Purpose and intent. The purpose of the water quality impact assessment is to:
(1)
Identify the impacts of proposed land disturbance, development or redevelopment on water quality and land within RPAs and other environmentally-sensitive lands;
(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)
To protect individuals from investing funds for improvements proposed for a location on lands unsuited for such development because of high ground water, erosion, or vulnerability to flood and storm damage; and
(4)
Specify mitigation which will address water quality protection.
(B)
Water quality impact assessment required.
(1)
A water quality impact assessment is required for:
(a)
Any proposed land disturbance, development or redevelopment within a RPA including any buffer area encroachment as provided for in § 154.153; and
(b)

(1)
A minor water quality impact assessment pertains only to land disturbance, development or redevelopment within the CBPAs that causes no more than 5,000 square feet of land disturbance and proposes to encroach into the landward 50 feet of the 100-foot buffer area. A minor assessment must demonstrate through acceptable calculations that the undisturbed buffer area together with necessary best management practices will result in removal of no less than 75 percent of sediments and 40 percent of nutrients from post-development stormwater runoff and that will retard runoff, prevent erosion and filter non-point source pollution and so achieve the equivalent of the full undisturbed 100-foot wide buffer area.
(2)
A minor assessment shall include a site drawing to scale that shows the following:
(a)
Location of the components of the RPA, on site or within a 100-foot wide area abutting the site, including the 100-foot wide buffer area and any water body with perennial flow:
(b)
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;
(c)
Type and location of proposed best management practices to mitigate the proposed encroachment; and
(d)
Location of existing vegetation onsite, including the number and type of trees and other vegetation to be removed in the buffer to accommodate the encroachment or modification and a revegetation plan that supplements the existing buffer vegetation in a manner that provides for pollutant removal, erosion and runoff control.
(D)
Major water quality impact assessment.
(1)
A major water quality impact assessment shall be required for any land disturbance development, or redevelopment that:
(a)
Exceeds 5,000 square fee of land disturbance within the CBPAs and proposes to encroach into the landward 50 feet of the 100-foot wide buffer area;
(b)
Proposes to disturb any portion of the seaward 50 feet of the 100-foot wide buffer area or any other component of an RPA; or
(c)
Is located solely in an RMA and is deemed necessary by the zoning administrator.
(2)
The information required in this section shall be considered a minimum, unless the zoning 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 water quality assessment that accompanies a site plan or subdivision application:
(a)
All of the information required in a minor water quality impact assessment, as specified in division (C) above;
(b)
