Additional comments or conditions may be added or eliminated based on further review.): [Each comment is preceded by the applicable reference, which is to the Subdivision /Zoning Ordinances unless otherwise specified.] 1. [Comment] It appears that a 24' access easement is being provided for the future Phase 1113. For your information, should this property be subdivided to split Phases IIA and 116, a minimum 30' private street easement would be required, and private street approval would be necessary for frontage for Phase 1113. Similarly, if you plan to subdivide Phase IIA from Phase 1, the existing 24' access easement would need to be increased to a minimum of 30' to qualify for private street approval. 2. [Comment] The parking and building setback lines along Route 29 have two different labels. In one area they are refered to as 20' buffer and 50' building setback, and in another they are labeled 10' parking setback and 30' building setback; please correct on all sheets. 3. [32.5.2(a)] The boundary information provided does not include reference to TMP 045000000111 B0, and the cover sheet provides the incorrect acreage for TMP 04500000011100; please verify and provide accurate existing boundary lines and acreage information. 4. [32.5.2(a)] Add AIA (Airport Impact Area) to the Zoning note. Please also document the waiver granted for disturbance of critical slopes including the associated conditions of approval by reference to the approval letter for SDP 200400045 dated October 28, 2005. 5. [32.5.2(b)] While the maximum building height on HC zoned land is 65', any building height in excess of 35' requires an additional 2' of setback for each 1' in height above 35'. The cover sheets states "`proposed building height is approximately 40' to highest peak ". It appears this is referring to the front fagade treatment, which is exempt from the setback provisions. Please provide the actual maximum building height (not approximate) to verify that no additional setback is required. 6. [32.5.2(b) & 4.12.4(a)] The number of parking spaces provided may not exceed the number of spaces required by more than twenty (20) percent. The site plan indicates that the requirement is being exceeded by 54 %. Please either reduce the number of parking spaces to a maximum of 209, or request a waiver from this section of the ordinance. 7. [32.5.2(b)] Provide the maximum amount of impervious cover on the Cover Sheet. 8. [32.5.2(b)] Provide the maximum amount of paved parking and vehicular circulation area on the Cover Sheet and Landscape Sheet. 9. [32.5.2(1)] Please show the location of other existing and proposed utilities and utility easements, including telephone, cable, electric and gas easements. 10. [32.5.2(n)] Label the length of the load ing /dumpster area. 11. [32.6.2(g)] Indicate all utility and drainage easements outside the right -of -way of public streets. Any new easements may be generally shown and dedicated by separate plat. All water and sewer facilities to be dedicated to public use and the easements for those facilities and shall be identified by a statement that the facilities are to be dedicated to the Albemarle County Service Authority. 12. [32.6.20) & Comment] The landscape plan submitted for ARB review is different from the plan shown in the Site Plan set; these plans must match before a full landscape plan review will be completed. The following comments are for reference when submitting the revised plan. 13. [32.6.20) & Comment] Many of plant labels have conflicts with other lines /labels on the sheet and are difficult to read; please make sure all labels are legible. 14. [32.6.20) & Comment] The plant counts provided for Cornus florida and Ilex x 'Nellie R. Stevens' appear to be incorrect; please verify and revise. 15. [32.6.20) & Comment] Many of the proposed plantings appear to have site conflicts. Some are shown outside of the site, some are in utility easements and some are directly on top of proposed utilities and drainage structures. Please move plants into more suitable locations or provide approval from the associated agency (VDOT, ACSA, etc) that they will allow the plantings within their property /easement. 16. [32.6.20), 32.7.9.4(b) & Condition of approval] Existing trees may be preserved in lieu of planting new plant materials in order to satisfy the landscaping and screening requirements of section 32.7.9 or to meet conditions of approval, subject to the agent's approval. It appears the Preliminary Site Plan and first Final Site Plan were approved with a condition that certain trees along the border of the 20' undisturbed buffer be marked and preserved. The landscape plan should show the trees to be preserved, the limits of clearing, the location and type of protective fencing, grade changes requiring tree wells or walls, and trenching or tunneling proposed beyond the limits of clearing. The conservation checklist refers to these elements, but they don't appear to be present on the plan. 17. [32.6.20) & 32.7.9.5(a)] An area of at least five (5) percent of the paved parking and vehicular circulation area shall be landscaped with trees or shrubs. Neither the areas of street trees and shrubs required by sections 32.7.9.5(d) and (e) nor shrubs planted between a parking area and the building shall be counted toward the minimum landscaped area for a parking lot. As noted above, the square footage of `paved parking and vehicular circulation area' has not been provided. Additionally, the 5% requirement refers to square footage of planting space, not tree canopy (as provided on the plan submitted). Please provide all relevant information to verify this requirement is satisfied. 18. [32.6.20) & 32.7.9.5(b)] The 5% landscaped area required shall be planted with a mixture of shade trees and shrubs and shall include one (1) large or medium shade tree per ten (10) parking spaces or portion thereof, if five (5) spaces or more. The Acer rubrum, Platanus acerifolia, and Ulmus parvifolia are the only trees provided that are on the current list of recommended large or medium shade trees approved by the agent; therefore there are 31 parking lot trees provided, not 37 as indicated on the plan. 19. [32.6.20) & 32.7.9.7] Please extend the additional screening plants on top of the retaining wall to the end of the adjacent residential district. 20. [32.6.20) & 32.7.9.8] It appears that the site acreage used to calculate the tree canopy requirement is incorrect. The plan only lists the acreage for TMP 45 -110, when TMP 45 -110A should also be included; please revise. Additionally, provide information as to how the canopy numbers for the Taxodium distichum and Magnolia grandflora were determined. 21. [32.6.2(k) & 4.17] Lighting comments provided with the ARB review apply to the Site Plan as well. Also, it appears that the lighting plan submitted for ARB review shows building mounted fixtures, while the plan included with the Site Plan set does not. All proposed lighting fixtures must be included on the lighting plan included in the Site Plan set. 22. [32.6.2(k) & 4.17] Two of the pole fixtures are proposed directly on top of storm drain pipe; please correct this conflict. 23. [32.6.2(k) & 4.17] Please indicate that the proposed pole fixture will have a flat lens. 24. [32.6.2(k) & 4.17] The lighting plan indicates that a LLF of 0.75 was used to create the photometric plan. Albemarle County requires that the LLF be 1.0; revise the photometric plan using the proper LLF. 25. [32.6.2(k) & 4.17] Provide the following standard lighting note on the lighting plan: Each outdoor luminaire equipped with a lamp that emits 3, 000 or more initial lumens shall be a full cutoff luminaire and shall be arranged or shielded to reflect light away from adjoining residential districts and away from adjacent roads. The spillover of lighting from luminaires onto public roads and property in residential or rural areas zoning districts shall not exceed one -half footcandle. 26. [Comment] Provide documentation of all off -site easements, including grading and off -site plantings. 27. [Comment] Provide the deed book and page references for all existing utility easements located on the property. 28. [Condition of Preliminary Approval] Architectural Review Board issuance of a Certificate of Appropriateness. 29. [Condition of Preliminary Approval] Virginia Department of Transportation approval of entrance design, signal improvements, frontage and turn lane improvements as well as any associated road plans and drainage plans. 30. [Condition of Preliminary Approval] Albemarle County Service Authority approval including approval of the design of the relocated sanitary sewer meeting ACSA standards with no portion located within storm water management facilities. 31. [Condition of Preliminary Approval] The 18' retaining wall on the northern side of the site cannot disturb the undisturbed buffer for a footing or reinforcing grid. The plan must be revised as necessary, or provide computations, details and construction methods to avoid disturbance of the buffer. The preliminary plan did not show a retaining wall where it is currently proposed in Phase IIA; this condition is applicable to the proposed wall as well. 32. [Condition of Preliminary Approval] Grading to the edge of the undisturbed wooded buffer on the sides of the site will likely cut tree root systems, damaging and eventually killing trees. On final plans, the grading should be moved back, or specific trees surveyed and marked on plans to ensure survivability of trees within the undisturbed buffer. 33. [Condition of Preliminary Approval] Fire Marshall approval. 34. [Condition of Preliminary Approval] Building Official approval. 35. [Condition of Preliminary Approval] The final site plan shall be subject to Planning Commission review. This submittal will be scheduled on the consent agenda once ARB approval is obtained and the majority of the site plan issues have been resolved. 36. [Comment] This site plan cannot be approved until Engineering, ACSA and VDOT completed their reviews and grant their approval; comments will be forwarded upon receipt. ARB, Fire /Rescue, inspections, and E911 comments have been provided.
