- CHESAPEAKE BAY PRESERVATION AREA OVERLAY DISTRICT2
State Law reference— Chesapeake Bay Preservation Act, Code of Virginia, § 62.1-44.2 et seq.
This district shall be known and referenced as the "Chesapeake Bay Preservation Area Overlay District" of the town.
(Code 1989, § 24-56; Ord. eff. 6-5-1962; Ord. of 3-24-1997; Amd. of 7-14-1997; Ord. of 6-23-2003)
(a)
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. The health of the bay is vital to maintaining the town's economy and the welfare of its citizens.
(b)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including nonpoint 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 town council as Chesapeake Bay Preservations Areas (hereinafter "CBPAs"), which include resource protection areas (hereinafter "RPAs") and resource management areas (hereinafter "RMAs"), need to 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.

Development in RPAs may be allowed only if it is water-dependent, or it constitutes redevelopment; or it constitutes development or redevelopment within the intensely developed area.
(1)
A new or expanded water-dependent facility may be allowed, provided that:
a.
It complies with the performance criteria set forth in section 38-312.
b.
Any non-water-dependent component is located outside of resource protection areas.
c.

(Code 1989, § 24-65; Ord. eff. 6-5-1962; Ord. of 3-24-1997; Amd. of 7-14-1997; Ord. of 6-23-2003; Ord. of 6-24-2013, § 24-69(c))
(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 nonpoint source pollution from new development; achieve a ten percent reduction in nonpoint source pollution from redevelopment; and achieve a 40 percent reduction in nonpoint source pollution from agricultural uses.
(b)
General performance standards for development and redevelopment.
(1)
Land disturbance shall be limited to the area necessary to provide for the 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.
Impervious cover shall be minimized consistent with the proposed use or type of development.
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 practicable, consistent with the use or development allowed 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.
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 clearing or grading, suitable protective barriers, such as safety fencing, shall be erected five feet outside of the drip-line 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.
(4)
Any development or redevelopment exceeding 2,500 square feet of land disturbance shall be accomplished through a plan of development process, as set forth in plan of development requirements of this article, prior to any clearing or grading of the site or the issuance of any building permit, to ensure compliance with all applicable requirements of this article.
(5)
Notwithstanding any other provisions of this article or exceptions or exemptions thereto, any land disturbing activity exceeding 2,500 square feet, including construction of all single-family houses, septic tanks and drain fields, shall comply with the requirements of the local erosion and sediment control ordinance.
(6)
All onsite sewage disposal systems not requiring a Virginia Pollutant Discharge Elimination System (VPDES) permit shall be pumped out at least once every five years, in accordance with the provisions of the county health code.
(7)
For any development or redevelopment, stormwater runoff shall be controlled by the use of best management practices consistent with the water quality provisions of the state stormwater management regulations (4 VAC 3-20-10 et seq.) that achieve the following:
a.
For development, the post-development nonpoint source pollution runoff load shall not exceed the pre-development load, based on the calculated average impervious cover of 34 percent.
b.
For sites within IDAs or other isolated redevelopment sites, the nonpoint source pollution load shall be reduced by at least ten percent. The zoning administrator may waive or modify this requirement for redevelopment sites that originally incorporated best management practices for stormwater runoff quality control, provided the following provisions are satisfied:
1.
In no case may the post-development nonpoint 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 nonpoint 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 article.
c.
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 nonpoint source pollution loadings can be substituted for the existing development loadings.
(8)
Prior to initiating grading or other onsite 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 plan of development requirements of this article.
(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 buffer area of vegetation that is effective in retarding runoff, preventing erosion and filtering nonpoint 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 water body with perennial flow. The full buffer area shall be designated as the landward component of the RPA.
(3)
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 subject to approval by the zoning administrator, only to provide for reasonable sight lines, access paths, general woodlot management and best management practices including those that preventing upland erosion and concentrated flows of stormwater, 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 nonpoint source pollution from runoff.
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 and thinning of trees may be allowed pursuant to sound horticultural practices incorporated into standards adopted by the town.
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.
b.
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 zoning administrator may permit encroachments into the buffer area in accordance with plan of development requirements of this article 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 equal to the area or encroachment into the buffer shall established elsewhere on the lot or parcel.
3.
The encroachment may not extend into the seaward 50 feet of the buffer area.
c.
Redevelopment within IDAs will be exempt from the buffer area.
(Code 1989, § 24-66; Ord. eff. 6-5-1962; Ord. of 3-24-1997; Amd. of 7-14-1997; Ord. of 6-23-2003)
(a)
The purpose of a water quality impact assessment is to:
(1)
Identify the potentially adverse impacts of proposed development on water quality and lands within Chesapeake Bay Preservation Areas.
(2)
Ensure that, where development takes place within Chesapeake Bay Preservation Areas, it will be located on those portions of a site and in a manner that will be least disruptive to the natural functions of resource protection areas and other sensitive lands.
(3)
Specify means to avoid, minimize or mitigate the impacts of development for water quality protection.
(b)
A water quality impact assessment shall be required:
(1)
For any land disturbance within a resource protection area.
(2)
For any buffer area encroachment.
(3)
For any variance or exception provided for in section 38-347.
(4)
The zoning administrator may waive the requirement for a water quality impact assessment (WQIA) only for projects located outside of the RPA, as the regulations clearly require a WQIA for any land disturbance within a RPA.
(5)
Where a water quality impact statement is deemed necessary by the zoning administrator to evaluate the potential impacts of the development upon water quality or a resource protection area by reason of the unique characteristics of the site or the intensity of the proposed use or development.
(c)
Contents of a water quality impact assessment. The following elements shall be included in a water quality assessment unless one or more such elements shall, in the judgment of the zoning administrator, not be reasonably necessary in determining the impact of the proposed development:
(1)
Location of the components of the RPA, including the 100-foot RPA buffer.
(2)
Location and nature of any proposed encroachments into the RPA buffer area, including the type of paving material; areas of clearing or grading and the location of any structures, driveways and other impervious cover.
(3)
Type and location of proposed stormwater management facilities and best management practices necessary to comply with performance standards for stormwater management contained in section 38-312(b)(8).
(4)
Calculation of pre- and post-development pollutant loading in accordance with section 38-312(b)(8).

a.
The necessity of the proposed encroachment into the buffer area and the ability to place improvements elsewhere on the site to avoid disturbance of the buffer area.
b.
Within any RPA, denial of the proposed development would result in the loss of use of a lot or parcel of record as of October 1, 1989.
c.
The disturbance of wetlands will be minimized.
d.
Impervious surface is minimized.
e.
The development as proposed meets the purpose and intent of this article.
f.

(a)
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. The health of the bay is vital to maintaining the town's economy and the welfare of its citizens.
(b)
The Chesapeake Bay waters have been degraded significantly by many sources of pollution, including nonpoint 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 town council as Chesapeake Bay Preservations Areas (hereinafter "CBPAs"), which include resource protection areas (hereinafter "RPAs") and resource management areas (hereinafter "RMAs"), need to 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.

(Code 1989, § 24-65; Ord. eff. 6-5-1962; Ord. of 3-24-1997; Amd. of 7-14-1997; Ord. of 6-23-2003; Ord. of 6-24-2013, § 24-69(c))
(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 nonpoint source pollution from new development; achieve a ten percent reduction in nonpoint source pollution from redevelopment; and achieve a 40 percent reduction in nonpoint source pollution from agricultural uses.
(b)
General performance standards for development and redevelopment.
(1)
Land disturbance shall be limited to the area necessary to provide for the 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.
Impervious cover shall be minimized consistent with the proposed use or type of development.
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 practicable, consistent with the use or development allowed 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.
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 clearing or grading, suitable protective barriers, such as safety fencing, shall be erected five feet outside of the drip-line 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.
(4)
Any development or redevelopment exceeding 2,500 square feet of land disturbance shall be accomplished through a plan of development process, as set forth in plan of development requirements of this article, prior to any clearing or grading of the site or the issuance of any building permit, to ensure compliance with all applicable requirements of this article.
(5)
Notwithstanding any other provisions of this article or exceptions or exemptions thereto, any land disturbing activity exceeding 2,500 square feet, including construction of all single-family houses, septic tanks and drain fields, shall comply with the requirements of the local erosion and sediment control ordinance.
(6)
All onsite sewage disposal systems not requiring a Virginia Pollutant Discharge Elimination System (VPDES) permit shall be pumped out at least once every five years, in accordance with the provisions of the county health code.
(7)
For any development or redevelopment, stormwater runoff shall be controlled by the use of best management practices consistent with the water quality provisions of the state stormwater management regulations (4 VAC 3-20-10 et seq.) that achieve the following:
a.
For development, the post-development nonpoint source pollution runoff load shall not exceed the pre-development load, based on the calculated average impervious cover of 34 percent.
b.
For sites within IDAs or other isolated redevelopment sites, the nonpoint source pollution load shall be reduced by at least ten percent. The zoning administrator may waive or modify this requirement for redevelopment sites that originally incorporated best management practices for stormwater runoff quality control, provided the following provisions are satisfied:
1.
In no case may the post-development nonpoint 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 nonpoint 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 article.
c.
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 nonpoint source pollution loadings can be substituted for the existing development loadings.
(8)
Prior to initiating grading or other onsite 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 plan of development requirements of this article.
(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 buffer area of vegetation that is effective in retarding runoff, preventing erosion and filtering nonpoint 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 water body with perennial flow. The full buffer area shall be designated as the landward component of the RPA.
(3)
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 subject to approval by the zoning administrator, only to provide for reasonable sight lines, access paths, general woodlot management and best management practices including those that preventing upland erosion and concentrated flows of stormwater, 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 nonpoint source pollution from runoff.
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 and thinning of trees may be allowed pursuant to sound horticultural practices incorporated into standards adopted by the town.
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.
b.
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 zoning administrator may permit encroachments into the buffer area in accordance with plan of development requirements of this article 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 equal to the area or encroachment into the buffer shall established elsewhere on the lot or parcel.
3.
The encroachment may not extend into the seaward 50 feet of the buffer area.
c.
Redevelopment within IDAs will be exempt from the buffer area.
(Code 1989, § 24-66; Ord. eff. 6-5-1962; Ord. of 3-24-1997; Amd. of 7-14-1997; Ord. of 6-23-2003)
(a)
The purpose of a water quality impact assessment is to:
(1)
Identify the potentially adverse impacts of proposed development on water quality and lands within Chesapeake Bay Preservation Areas.
(2)
Ensure that, where development takes place within Chesapeake Bay Preservation Areas, it will be located on those portions of a site and in a manner that will be least disruptive to the natural functions of resource protection areas and other sensitive lands.
(3)
Specify means to avoid, minimize or mitigate the impacts of development for water quality protection.
(b)
A water quality impact assessment shall be required:
(1)
For any land disturbance within a resource protection area.
(2)
For any buffer area encroachment.
(3)
For any variance or exception provided for in section 38-347.
(4)
The zoning administrator may waive the requirement for a water quality impact assessment (WQIA) only for projects located outside of the RPA, as the regulations clearly require a WQIA for any land disturbance within a RPA.
(5)
Where a water quality impact statement is deemed necessary by the zoning administrator to evaluate the potential impacts of the development upon water quality or a resource protection area by reason of the unique characteristics of the site or the intensity of the proposed use or development.
(c)
Contents of a water quality impact assessment. The following elements shall be included in a water quality assessment unless one or more such elements shall, in the judgment of the zoning administrator, not be reasonably necessary in determining the impact of the proposed development:
(1)
Location of the components of the RPA, including the 100-foot RPA buffer.

(1)
Upon the completed review of a water quality impact assessment, the zoning administrator will determine if any proposed modification or reduction to the buffer area is consistent with the purpose and intent of this article or if the proposed development is consistent with the purpose and intent of this article. The zoning administrator will make a finding based on the following criteria in conjunction with plan of development requirements:
a.
The necessity of the proposed encroachment into the buffer area and the ability to place improvements elsewhere on the site to avoid disturbance of the buffer area.
b.
Within any RPA, denial of the proposed development would result in the loss of use of a lot or parcel of record as of October 1, 1989.
c.
The disturbance of wetlands will be minimized.
d.
Impervious surface is minimized.
e.
The development as proposed meets the purpose and intent of this article.
f.
Proposed erosion and sediment control devices are adequate to achieve the reductions in runoff and prevent offsite sedimentation.
g.
Proposed stormwater management facilities and practices are adequate to control the stormwater runoff to achieve the required standard for pollutant control.
h.
The development will not result in unnecessary destruction of plant materials on site.
i.
The cumulative impact of the proposed development when considered in relation to other development in the vicinity, both existing and proposed, will not result in a significant degradation of water quality.
(2)
The zoning administrator may request review of the water quality impact assessment by the Chesapeake Bay Local Assistance Department (CBLAD). Any comments by CBLAB will be considered by the planning commission provided that such comments are provided by CBLAB within 30 days of the request.
