Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Alternate locations for the access road to the site were investigated. A residential development is located northeast of the site. Hartsfield Forest Drive, one of the secondary roads within the residential development, is proposed to be extended to the northeast corner of the site. However, according to the City of Greensboro, this road is located within a residential zoning district and cannot be used for business traffic. Therefore, the property is only accessible from Burlington Road. The location of the road crossing was designed to minimize the amount of fill to accommodate the road crossing and avoid additional impacts to the stream and wetlands to the east. The access drive to the site will maintain the minimum required width to minimize impacts to the intermittent stream. Headwalls were designed at the ends of the culvert to reduce the footprint of the fill required to accommodate the road crossing. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. It would greatly reduce the risk for surface water impacts to complete construction of the road crossing during dry periods of the summer when base flow in the intermittent stream is reduced. Stormwater will be addressed by installing BMPs until permanent vegetation is established. Headwalls were designed at the ends of the culvert to reduce the footprint of the fill required to accommodate the road crossing. 2.

Assign points to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the highest quality.

Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potential drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth in channel bottom (as indicator of intermittent flow), etc. 2. Human-caused alterations may include relocation, channelization, excavation, riprap, gabions, culverts, levees, berms, spoil piles adjacent to channel, etc. 3. The riparian zone is the area of vegetated land along each side of a stream or river that includes, but is not limited to, the floodplain. Evaluation should consider width of riparian area with respect to floodplain width, vegetation density, maturity of canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.), presence of drainage tiles, logging activities, other disturbances which negatively affect function ofthe riparian zone. 4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from commercial and industrial sites, agricultural fields, pastures, golf courses, swimming pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors, discolored water, suds, excessive algal growth may also provide evidence of discharge. 5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of adjacent wetlands, seeps, and springs feeding channel, reduced soils in channel bottom. 6. Presence of floodplains may be determined by topography and the slope of the land adjacent to the stream, terracing, the extent of development within the floodplain, FEMA designation ifknown, etc. 7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data, testimony oflocal residents, entrenchment ratio, etc. Note that indicators may relic and not a result of regular flooding. 8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream channel, and may be indicated by beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National Wetland Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.) 9. Channel sinuosity should be evaluated with respect to the channel size and drainage area, valley slope, topography, etc. 10. To evaluate sediment deposition within the channel consider water turbidity, depth of sediment deposits forming at point bars and in pools, evidence of eroding banks or other sediment sources within watershed (construction sites, ineffective erosion controls). In rare cases, typically downstream of culverts or dams, a sediment deficit may exist and should be considered in scoring. 11. When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to the stream), average size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), and diversity of particle size (riprap is excluded). 12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent development and increased impervious surface area resulting in greater runoff in the watershed. 13. Evaluation should consider presence of major bank failures along the entire reach under evaluation, including uprooted trees on banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, etc. 14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate the bank relative to the amount of exposed soil on the bank and the normal water elevation. 15. Assessment of agriculture, livestock, and/or timber production impacts should address areas of stream bank destabilization, evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high nutrient levels entering streams, drainage ditches entering streams, loss of riparian zone due to logging, etc. 16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles and pools should be considered with respect to topography (steepness of terrain) and local geology (type of substrate). Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed streams with little or no gravel that form under low shear stress conditions, whereas, dunes and antidunes form under moderate and high shear stresses, respectively. Dunes are the most common bed forms found in sand bed streams. 17. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look for include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root mats, undercut banks, overhanging vegetation, pool and riffle complexes, wetland pockets adjacent to channel, etc. 18. Evaluation should consider the shading effect that riparian vegetation will provide to the stream during the growing season. Full sun should be considered worst case, while good canopy coverage with some light penetration is best case. 19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in the streambed. The overall size of the average particle in the streambed should be considered (smaller rocks will have smaller gaps). 20. Evaluation should be based on evidence of stream invertebrates gathered from multiple habitats. Scores should reflect abundance, taxa richness, and sensitivity of stream invertebrate types. (see attached examples of common stream invertebrates on page 4). 21. Evaluation should include evidence of amphibians in stream channel. Tadpoles and frogs should receive minimum value, while salamanders, newts, etc. may be assigned higher value. 22. Evaluation offish should consider the frequency and, if possible, the variety of different fish taxa observed. 23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands, evidence of fishing, etc.) of any animals using the streambed or riparian zone, to include small and large mammals, rodents, birds, reptiles, insects, etc. 3 Common Stream Invertebrates T P 11 . h b fi d' d r t SensitIve axa- o utlOn sensItIve orgamsms t at may e oun In goo qua Ity wa er.

OF MCLEANSVILLE ("Church"), a North Carolina corporation. RECITALS: Ashton has acquired from Church, by Deed dated July 29, 2008 and recorded in the Guilford County Registry in Book 6921 at Page 81, a parcel of land ("Ashton Property") consisting of approximately 10.203 acres with frontage on Burlington Road, leaving Church with a remainder of property ("Church Property") consisting of approximately 42.487 acres on which presently is located facilities of Church and for which Church has development plans for additional Church facilities. Ashton intends to construct on the Ashton Property a skilled nursing care facility ("Care Facility"), and, as a part of its agreement with Church for the acquisition of the Ashton Property, Church has agreed with Ashton that Church will permit GREENSBORO 920809.5 Ashton to construct partially on the Church Property a water quality pond (the "Pond") in order to meet requirements of Guilford County and the City of Greensboro for water quality and watershed protection for the Ashton Property. The Pond will be constructed in the location shown on Exhibit A, attached hereto and incorporated herein by reference, and the structures and facilities, including without limitation, any and all pipes, conduits, drainage lines and other apparatus ("Pond Structures") for the Pond providing for discharge of water into and from the Pond also shall be constructed in the locations as shown on Exhibit A. The Pond Structures will be constructed by Ashton of such a size and capacity to meet presently anticipated future needs of Church, but the Pond will be constructed of such a size and capacity to meet the requirements for the Ashton Property. Ashton shall be solely responsible for the costs of construction of the Pond, the Pond Structures, all costs of maintenance of the Pond and Pond Structures, unless and until such time as Church should determine to enlarge the Pond to meet requirements for the Church Property, at which time Church will be solely responsible for the costs of enlargement of the Pond and will contribute to the costs of maintenance of the Pond, as hereinafter provided. Provided, however, should the Church cause construction or other activities to take place on the Church Property which contribute to sedimentation in the Pond, or otherwise impact the Pond in such a manner as to require additional costs of maintenance of the Pond, Church shall be solely responsible for such costs. Church wishes hereby to grant to Ashton perpetual nonexclusive easements to construct and maintain the Pond and the Pond Structures in the location shown on Exhibit A and, further, wishes to grant Ashton (i) a temporary grading and construction easement over all areas shown therefor on Exhibit A and (ii) a temporary easement for access during construction over and upon the existing dirt drive, the location of which generally also is shown on Exhibit A. The design and plans for the Pond will comply with applicable laws and GREENSBORO 920809.5 2 ordinances of Guilford County, the City of Greensboro, and any other entity having jurisdiction therefor, and, prior to submittal to appropriate governmental offices for approval, shall be submitted to Church for Church's approval, which will not be unreasonably withheld. NOW, THEREFORE, for and in consideration of the covenants and agreements hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Ashton and Church hereby agree as follows: 1. Grant of Easements. Church hereby grants and conveys to Ashton, its successors and assigns, the following: (a) Pond and Pond Structure Easements.

These Pond and Pond Structure Easements are for the purpose of (i) constructing the Pond and Pond Structures and allowing drainage from the Ashton Property to be collected into and retained in the Pond and to be discharged therefrom in accordance with the terms and conditions set forth herein and in such a manner as is necessary to comply with the ordinances of Guilford County, the City of Greensboro or other GREENSBORO 920809.5 3 governmental entity having jurisdiction relating to storm water runoff and watershed protection and (ii) for access to the Pond and the Pond Structures for required maintenance thereof. It is the express intent of Church and Ashton that this grant of easement shall not entitle any property other than the Ashton Property and the Church Property to utilize the Pond for compliance with watershed requirements of Guilford County, the City of Greensboro or other governmental entity having jurisdiction relating to storm water runoff and watershed protection without the express written consent of Church and Ashton. (b) Grading and Construction Easement. A temporary grading and construction easement ("Grading and Construction Easement") over all areas shown and designated on Exhibit A as "Grading Easement", for the purpose of necessary grading and construction of the Pond, Pond Structures and the Care Facility. (c) Temporary Construction Access Easement. A temporary easement ("Access Easement") over and upon and to utilize the existing dirt drive ("Drive") in the location generally shown on Exhibit A for access as required to construct the Pond, the Pond Structures and the Care Facility. Ashton will make such improvements to the Drive, including without limitation, adding gravel, grading and leveling, as necessary to accomplish Ashton's construction activities. Upon completion of all of Ashton's construction activities, Ashton will leave the Drive in as good or better GREENSBORO 920809.5 4 condition as existed at the time of Church's granting of this Access Easement. 2. Oblie:ation to Maintain. Ashton shall be solely responsible for the construction, operation and maintenance of the Pond, which shall include maintaining the minimum sediment storage volume required by Guilford County, the City of Greensboro, or other governmental entity having jurisdiction, and maintaining any part of the Pond which is not properly functioning as originally designed and approved by Guilford County and the City of Greensboro. Provided, however, should Church, at any time as a result of construction or other activity on the Church Property, cause sedimentation in the Pond or otherwise result in costs attributable to activity on the Church Property, Church shall be solely responsible for such costs. In the event that Church should, at any time in the future, wish to utilize the Pond to meet storm water runoff and watershed protection requirements of Guilford County, the City of Greensboro, or other governmental entity having jurisdiction, in connection with improvements and additions to the Church Property, Church shall be solely responsible for any and all costs of enlarging the capacity of the Pond to meet such requirements. Thereafter, any ongoing costs of maintenance of the Pond, which shall include maintaining the minimum sediment storage volume required by Guilford County, the City of Greensboro, or other governmental entity having jurisdiction, and maintaining any part of the Pond which is not properly functioning as originally designed and approved by Guilford County and the City of Greensboro, shall be shared between Ashton and Church based upon the percentage of the Ashton and Church Property that drains into the Pond. Ashton and Church agree to share in the cost of any required maintenance on the Pond based upon the percentage calculated by taking the amount of drainage area from each site contributing to flow to the Pond and dividing it by the total drainage area flowing into the Pond. Any such GREENSBORO 920809.5 5 cost shall be paid by Ashton and reimbursed to Ashton from Church within thirty (30) days of receipt by Church of a certificate from Ashton setting forth: (a) The amounts expended for the operation and maintenance of the Pond; (b) The nature of such operation and maintenance; (c) The costs incurred in performing such operation and maintenance; and (d) That such operation and maintenance has been done in conformity with all applicable legal requirements and accepted and approved by any party having jurisdiction over the Pond, if applicable. The certificate shall be accompanied by paid invoices or other documentation itemizing such expenditures. In the event that Church fails, within thirty (30) days after receipt of such certificate, to reimburse Ashton for its share of the costs incurred, Ashton shall have a lien upon Church Property to secure the payment of any such amounts when and on the date that a claim of lien is filed of record in the Office of the Clerk of Superior Court of Guilford County, North Carolina. The claim of lien shall set forth the name and address of the record owner of the Church Property, and a description of the Church Property. Such lien shall be enforced in the same manner as a mortgage lien or deed of trust. Such lien shall be subordinate to any mortgage or deed of trust placed on all or any part of Church Property. This subordination shall be completely self-executing and shall require no further notice or the execution of any instrument by Ashton claiming a right of reimbursement. 3. Rie:ht of Governmental Entities. In the event that Ashton shall fail or refuse to maintain the Pond in such manner as required by Guilford County, the City of Greensboro, or GREENSBORO 920809.5 6 other governmental entity having jurisdiction over the Pond, either Church or such governmental entity shall have the full right and authority to cause any such maintenance to be performed, and the expense thereof, if not reimbursed to the governmental entity incurring the expense as herein provided, shall be a lien as provided herein upon the Ashton Property. 4. Amendment. This Agreement may be amended or terminated only with the agreement of Ashton and Church, and with the concurrence of Guilford County, the City of Greensboro, or other governmental entity having jurisdiction for watershed protection, which concurrence shall include approval of compliance with watershed protection requirements by some other means other than this Agreement. 5. Rie:hts under Easements. The rights, benefits and easements granted and conveyed pursuant to this Agreement shall be binding upon Ashton and Church, their successors and assigns, to have and to hold the aforesaid easements, rights and benefits and all privileges and appurtenances thereto belonging to Ashton and Church as herein provided. 6.

Fax 335-3141 www.ecologic-nc.com MEMORANDUM To: Marc Chambers, AIA, TRG Architecture Copy: Jerry Coble, Calvary Baptist Church Subject: Water Quality Permitting, Birch Creek Road Site From: Mark Taylor, PE Date: February 24, 2005 All comments are preliminary and subject to verification. As both regulators pointed out, final determinations of permitting and mitigation requirements can only be made when an application is submitted with a site development plan showing proposed impacts. Jurisdictional Determinations: USACE: NCDWQ: Delineated wetlands (not "isolated") are jurisdictional, including the area above the pond. No "mitigatable" streams are present except possibly below the dam to the west. The determination of jurisdictional streams (perennial or intermittent) is left to NCDWQ. (Andrea Wade site visit) Wetlands are as determined by USACE. Two additional "isolated" wetlands may occur as noted on the plan (2 circles). The "banana shaped" channel in the NE comer is ephemeral (non-jurisdictional). The stream below the dam (west) is probably intermittent and may become perennial further west. (Daryl Lamb site visit) Guilford County: Buffer requirements only apply to perennial streams feeding Lake McIntosh, so this should not be an issue except possibly west of the dam. (Warren Simmons personal communication) Permitting Implications: USACE: A CW A 404 Nationwide Permit (NWP) 39 is most probable and required for wetland impacts> 1/1 0 acre. The limits of cumulative impacts are 1/2 acre of wetlands and 300 If of perennial stream. A NWP 18 may be added if needed to allow limited filling of the wetland above the pond (max. 25 CY cut or fill "below the plane of the ordinary high water mark"). All impacts are subject to mitigation (but not likely in this case). Technology Serving Ecology Memo - Water Quality Pennitting, Birch Creek Road Site NCDWQ: A CWA 401 Water Quality Certification (WQC #3402) will accompany the NWP 39 or 18. Mitigation thresholds are> or = 150 If of perennial stream and > or = 1 acre wetlands (cumulative impacts for project). Added stormwater requirements may apply, but this determination is still pending. Site Development Plan: Clearly the alternative plan is more favorable from an avoidance and minimization perspective. The preferred plan looks permitable under the permitting strategy outlined above, with careful attention to cumulative impacts needed. It would be best to limit impacts to the pond area, and to avoid altogether plans to retrofit the pond for stormwater or sediment control purposes. If there is any consideration of abandoning the pond in the future, future site use implications need to be addressed ahead of time, as wetland and stream issues may still apply. Schedule Implications: Permitting as outlined above should be possible within 90-120 days or less from finalization of the site development plan, but anything is possible depending on the final plan. The fewer impacts, the quicker and easier permitting will be. We will need 2 to 4 weeks to prepare and submit the application depending on our work load at the time. 2/24/05 2 EcoLogic
