Coger Midlothian Magisterial District East line of Turner Road REQUEST: An exception to the requirements of the Chesapeake Bay Preservation Ordinance (CBPO) to allow encroachment into the Resource Protection Area (RPA). RECOMMENDATION Recommend approval with the one condition below for the following reasons: A. A Water Quality Impact Assessment (WQIA) has been approved. B. The six (6) findings, as required by Section 19-23 5 (b)(1) have been satisfied. C. The proposed development is consistent with the Chesapeake Bay Preservation Or finance. f;(1NT~TTT(1N~ The mitigation measures outlined in the 601 Turner Road -Water Quality Impact Assessment, dated March 25, 2008, prepared by Cliff Coger, Carl Duncan P.E., L.S., Angela Whitehead, CPSS shall be incorporated into the site plan review process and such measures shall be implemented. The Department of Environmental Engineering may approve alternative mitigation measures if it is determined that such alternatives will not increase impacts to the RPA or downstream water bodies. (EE) (NOTE: Approval of this exception does not convey any privileges which would limit the imposition of flood plain ordinance and policy requirements by the Environmental Engineering Department.) Providing a FIRST CHOICE community through excellence in public service GENERAL INFORMATION Location: 601 Turner Road, located in the Pocoshock Creek drainage basin Tax ID 763-704-1556 Existin.~~ 0-2 Size: 5.9 acres Existing Land Use: Vacant Condition of Resource Protection Area: The tributary Pocosham Creek bisects the property. There are approximately 5.3 acres of existing RPA located on-site. Much of the RPA buffers are in good condition consisting of mature mixed hardwood forest and 2.6 acres of jurisdictional waters and forested wetlands associated with Pocosham Creek. Area of Proposed RPA Encroachment: The area of the encroachment for this proposed development will impact approximately 12,196 square feet (0.28 acres) of existing RPA vegetative buffer. PR(1P(I~AT, The applicant has requested an exception for potential impacts to lands within designated Chesapeake Bay Preservation Areas (CBPAs) and downstream water bodies. Implementation of the limits of CBPAs, which include Resource Protection Areas (RPAs) around an onsite perennial stream and wetlands, would render the parcel unusable. Because the parcel contains areas designated as CBPAs, the site is subject to the application of the county's Chesapeake Bay Preservation Ordinance (CBPO). The CBPO requirements of the Zoning Ordinance specify that a Resource Protection Area (RPA) buffer be established adjacent to perennial water bodies, to include connected and contiguous wetlands, and consist of an undisturbed 100 foot natural vegetative area. In order to meet the zoning, development and site requirements, the applicant has requested an encroachment into the 100 foot RPA buffer. This encroachment would allow for the development of a 3,725 square feet office building and parking lot. Of the 5.9-acre property, the amount of impervious cover will increase to approximately 14,810 square feet (0.34 acres) constituting 5.7 percent of the property. Approximately 12,196 square feet (0.28 acres) of existing RPA vegetative buffer will be converted into a portion of the proposed parking lot and office building. 2 08RW0379 JUN25-BOS-RPT ANAT,VCT~ To approve a Chesapeake Bay Preservation Ordinance (CBPO) exception request, the Board of Supervisors must determine whether the proposed development is consistent with the Ordinance and weather the six (6) findings, outlined below, as required by Section 19-23 5 (b)(1) have been satisfied. The applicant addressed these findings as part of the application process. The applicant's position can be found on Attachment A. The first criteria for granting such an exception is: 1. The requested exception is the minimum necessary to afford relief. The proposed development is the minimum size to accommodate the business and comply with other development requirements. 2. GNanting the exception shall not confer any special privileges upon the applicant that are denied by this division to other property owners who are subject to its pNOVisions and who are similarly situated. This request is the minimum necessary to use this property. This lot was recorded prior to the ordinance from which the Applicant is requesting an exception. 3. The exception request is in harmony with the purpose and intent of this division and will not result in a substantial detNiment to wateN quality. The proposed mitigation measures are to offset the 5.7% impervious area impact within the buffer by providing stormwater treatment and additional buffer to existing resources. 4. The exception request is not based upon conditions or circumstances that are self- cNeated oN self-imposed. Adoption of County's CBPO ordinance occurred after the creation of this lot and prior to the development. Exceptions may be granted provide the development meets certain development standards. 5. Reasonable and appropriate conditions are imposed, as warranted, that will ensure that the permitted activity will not cause a degradation of water quality. Mitigation for impacts to water quality include additional buffers, stormwater treatment and minimization of the development. 6. The Nequest is being made because of the particular physical surNOUndings, use, shape or topographical conditions of the specific property involved or property adjacent to or within 100 feet of the subject propeNty, oN a paNticular hardship to the owner will occur, as distinguished from a mere inconvenience, if the strict letter of this division is caNried out. 3 08RW0379 JUN25-BOS-RPT The request is being made specifically due to the topographical features of this site which causes the majority of the site to be within a Resource Management Area (RMA) or a RPA. The stream running through the site along with a VDOT drainage Swale and their associated wetlands bisect the site. These wetlands, along with their 100 feet buffers, occupy the majority of the developable portion of the site. The remaining developable area is a small triangle at the front left corner and a smaller area at the left rear. The proposed development, with impacts, is on the front left corner. Strict application of the RPA requirements would prohibit the use of the parcel. CONCLUSION The applicant has requested an exception for potential impacts to lands within designated Chesapeake Bay Preservation Areas (CBPAs). Implementation of the limits of CBPAs, which include Resource Protection Areas (RPAs), renders the parcel unusable. The proposed encroachment into the 100 foot buffer would permit some development with the majority of the parcel remaining in a natural state. The applicant proposes to locate the project on the parcel such that development will comply with zoning, building setbacks and development standards. The applicant can still maintain a reasonable use while reducing the impact to the riparian area along Pocosham Creek. Additionally, the applicant will mitigate the encroachment into the RPA buffer by voluntarily treating stormwater runoff and include additional protection of the remaining resources by establishing an additional riparian buffer. Staff believes the applicant demonstrated the proposed project meets the six findings as stated in Attachment A, prepared an approved VVQIA and provided reasonable mitigation, summarized in Attachment B, for the proposed encroachment to be granted. 4 08RW0379 JUN25-BOS-RPT ATTACHMENT - A Applicant's response to the six (6) findings as required by Section 19-235 (b)(1). ! 7 • ! 7T7 REQUEST FOR AN EXCEPTION TO THE REQUIREMENTS OF THE ZONING ORDINANCE Clifton M. Coger 601 Turner Road, Tax ID 763-704-1556 Provide the justification for the proposed exception and a discussion of how each of the following findings is met: 1. The requested exception is the minimum necessary to afford relief: The proposed development is the minimum parking area and smallest building that will allow the applicant to relocate his business to this site. In addition, the proposed development is less than the normal allowed development for anon-impact site. The county default level of development is 16% of the total site. Our proposed development is only 5.7%. 2. Granting the exception shall not confer upon the applicant any special privileges that are denied by this division to other property owners who are subiect to its provisions and who are similarly situated: This request is the minimum necessary to actually use this property. This lot existed prior to the ordinance that this exception is requesting. This request does not set a precedent that is not currently available to similar distressed property owners. 3. The exception request is in harmony with the purpose and intent of this division and will not result in a substantial detriment to water quality: The proposed development specifies mitigation measures to offset the 5.7% impervious area impact within the buffer. Normal development outside of the buffer area would be allowed to develop to 16% impervious with no additional requirements. we are proposing to impact the buffer area only and are mitigating this impact by proposing a BMP and adding additional offsetting buffer area at the rear of the site. 4. The proposed exception is not based upon conditions or circumstances that are self created or self imposed: The conditions are imposed by the adoption of County ordinance after the creation of this lot and prior to the development of this lot. The owner had no control over the implementation of this ordinance or its requirements. 5. Reasonable and appropriate conditions have been imposed, as warranted, to ensure that the permitted activity will not cause a degradation of water quality: The owner is proposing mitigation, additional buffers and minimizing the development to assure that no degradation of the water quality will occur with this development. The proposed development will not have any impact on the water quality of the site. 5 08RW0379 JUN25-BOS-RPT 6. The request is being made because of the particular physical surroundings, use, shape, or topographical conditions of the specific property involved or property adjacent to or within loo feet of the subject property, or a particular hardship to the owner will occur, as distinguished from a mere inconvenience, if the strict letter of this division is carried out: The request is being made specifically due to the topographical features of this site which causes the major majority of the site to be within an RMA area or an RMA Buffer Area. The stream running through the site along with a VDOT drainage Swale and their associated wetlands bisect the site. These wetlands along with their 100' buffers completely occupy the developable portion of the site. The only remaining area is a small triangle at the front left corner and a smaller area at the left rear. We are proposing to develop, with impacts, the front left corner and to include as buffer the left rear area. Without the exception, there is no possible way to develop the site and the parcel becomes unusable. This exception is not for convenience but is a true hardship due to the wetlands and buffers. 6 08RW0379 JUN25-BOS-RPT ATTACHMENT - B The outline below summarizes some of the measures submitted as part of the WQIA for the mitigation of the requested encroachment and water quality improvement. REQUEST FOR AN EXCEPTION TO THE REQUIREMENTS OF THE ZONING ORDINANCE Clifton M. Coger 601 Turner Road, Tax ID 763-704-1556 The following is a partial list of mitigation measures for the proposed encroachments to the RPA. A more detail discussion of the measures are on file within the document 601 Turner Road - Water Quality Impact Assessment, dated March 25, 2008. These measures will provide additional stormwater treatment and water quality benefits/improvements. The remaining environmental features will be protected during construction by maintaining erosion and sediment control standards. After construction the features will be protected by increased buffers and stormwater outlet protection which will create sheet flow, promote infiltration, reduce concentrated flows and reduce down stream erosion. 1. A FilterraTM treatment system will be used to treat parking lot and roof top stormwater runoff prior to entering the remaining RPA buffer. 2. The remainder of the forested property and onsite wetlands (2.9 acres) will remain undeveloped. 3. Educational signs detailing the location of the riparian buffer will be posted. 4. The area outside of the proposed development and remaining RPA will be designated as riparian buffer to offset the requested encroachment. This area is approximately 7,905 square feet (0.18 acres) in size and is located in the northeast corner of the subject parcel. 7 08RW0379 JUN25-BOS-RPT ~ ~ ^ ^~~~~ 1 Q 1 1 a y t a z W 1 ~ 1 ` , ~r a z r~ V U N D 1~ 1 1 Q~ "~ ~ U N I ~ U N . ~- ~l ~l U•-~~ l l l ~ ~ j 1 r f ~ ~ ~ 1 Q 1 r u. ..::::f.: ~ ~ W ::::::::: ~ J ~::~~~ .: ~ OC ~~~ ~ ~ ~ ~ ~~J~~ J ~ ~ ..::::....: ~ V y ~:::::::::: .. .~-~ ~ ...~.
