The number of stories for the proposed building is now shown in the plan. 6. 135.5.2(b)] The layout sheet indicates there are 14 parking spaces in the row closest to the building, but there are only 13 spaces shown; please revise. The parking layout has been substantially modified since the previous submittal and the parking counts have been updated and double-checked. 7. 135.5.2(b)] Provide the maximum amount of paved parking and vehicle circulation. The total amount of paved parking and vehicle circulation is now provided on sheet C6. 8. [35.5.2(e)] Show the existing landscape features (as described in 32.7.9.4) on the existing conditions sheet. The existing landscape features are now shown on the existing conditions sheet. 9. [35.5.2(h)] The revised floodplain line must be approved prior to final site plan approval. So noted. Now- 10. [35.5.2(i)] Label the existing streets. The existing streets are now labelled. 11. [35.5.2(i)] The design of Trailside Court appears to have changed from what was previously approved; an amended road plan must be submitted and approved. The changes include a cul-de- sac (of sorts) versus a courtyard, and a paver walk instead of a standard sidewalk. An amended road plan is included with this submittal. 12. [35.5.2(i)] Dimension the revised street turn-around area. Dimensions are now provided for the revised street turn-around area. 13. 135.5.2(j, k)] Verify that all lines and all necessary easements for proposed water, sewer and drainage facilities have been shown on the plan.

The deed book and page number is now shown for all existing utility easements. 14. [35.5.2(1)] Provide the location of any other existing or proposed utilities and utility easements including telephone, cable, electric and gas. All known existing and proposed utilities and easements are shown on this plan. 15. [35.5.2(n)] Clarify the location of the proposed walk that provides access to the building; the hatch pattern outside of the `walk' lines in some places and no lines exist in others. The drafting for the proposed walk that provides access to the building has been revised and clarified to consistently show lines and hatches where the walk will be located. 16. [35.5.2(n)] Dimension the sitting walls and provide a detail. Sitting walls are no longer proposed with this plan. 17. [35.5.2(n)] Dimension the dumpster pad. Dimensions are now provided for the dumpster pad. 18. 135.5.2(n)] Label all proposed lighting on the layout sheet. The proposed lighting locations have been updated and are now shown correctly in the site plan sheet. See sheet C4. 19. [35.5.2(n)] The lighting locations shown on the layout and utility sheets appear to be slightly different than what is shown on the lighting plan; verify that all locations are accurately shown on all sheets to demonstrate that no site conflicts exist. All proposed light pole and light fixture locations are now shown consistently throughout the plan. 20. [35.5.2(p) & 32.7.9.4(a)] Provide a landscape legend listing the number, species and planting size of all proposed plantings to demonstrate landscape plan and Code of Development requirements have been met. A landscape schedule and calculations are provided on sheet C6 detailing the proposed plantings and requirement criteria. 21. [35.5.2(p) & 32.7.9.4(b)] 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, subject to the agent's approval. If you intend to use existing trees to satisfy any of the landscape plan requirements, please include the following: 1. Areas and other features shown on landscape plan. The landscape plan shall show the trees to be preserved, the limits of clearing, the location and type of protective w %m fencing, grade changes requiring tree wells or walls, and trenching or tunneling proposed beyond the limits of clearing. We are not proposing to use any existing tree canopy to meet the required landscape canopy requirements. 2. Conservation checklist. The applicant shall sign a conservation checklist approved by the agent to ensure that the specified trees will be protected during construction. Except as otherwise expressly approved by the agent in a particular cast, the checklist shall conform to the specifications in the Virginia Erosion and Sediment Control Handbook, pages III-393 through 111-413, and as hereafter amended. We are not proposing to save any existing trees within the project area with this resubmittal. The conservation checklist has been removed from sheet C6. 22. [35.5.2(p),32.7.9.5 & COD Section IX] Clarify if previously approved street trees along Trailside Court will remain. Several of the previously approved street trees at the end of Trailside Court will be removed and replaced with the American Planetree as shown on sheet C6. 23. [35.5.2(p) & COD Section IX] Provide landscaping in the Plaza area that meets the requirements of Section IX. The plan now shows two bench walls around a concrete plaza. Flowering shrubs are proposed around the benches with red bud ornamentals interspersed with the street trees in this area. 24. 135.5.2(p) & COD Sections VII & IX] Provide information regarding the ground treatment in the plaza area. Section VII requires a concrete or brick patio and Section IX requires planting around that patio. The plaza area is now called out as concrete with a concrete sidewalk for ingress and egress. Landscaping is shown behind the bench walls as required. 25. [COD Section III] In order to comply with the Block description listed in the Code of Development, please provide two benches in the green space at the southern end of the parking lot in addition to the amenities provided in the plaza north of the proposed building. Two benches are now provided in the green space at the southern end of the parking lot. Two benches are also proposed and incorporated into the concrete plaza area at the end of Trailside Court. 26. [35.5.2(p),32.7.9.6 & COD Section IX] The table in Section IX requires large shade trees, ornamental trees and screening shrubs for the parking lot in Block 5; provide landscaping that meets this requirement. The landscaping plan has been revised to include the required number of large shade trees and ornamental trees. Flowering shrubs are also shown within the landscape islands. Please see sheet C6. 27. [35.5.2(p) & 32.7.9.6(a)] The landscape notes indicate 5% of 17,098 SF has been provided in landscape area. What is the 17,098 number referencing? The landscaping calculations have been revised to clarify that the 17,803 SF is the total pavement area within the parking area. The plan shows that there is an excess of internal planting area proposed within the site which meets the requirement of 5%. 28. [35.5.2(p) & 32.7.9.6(a)] One of the `landscaped areas' noted on the landscape plan does not have any landscaping proposed; provide trees and shrubs in any area that counts toward this requirement. The landscaping plan has been revised to show the required landscaping throughout the site. 29. [35.5.2(p) & 32.7.9.6(b)] The landscape plan notes indicate that there are 49 proposed parking spaces while the plan shows 48; please revise. The landscaping plan notes have been updated to list the same number of parking spaces as are shown in the plan. 30. [35.5.2(p),32.7.9.7 & COD Section IX] As noted above, the table in Section IX requires screening shrubs for the parking lot in Block 5; provide landscaping to meet this requirement and 32.7.9.7. The plan shows 32 colorado blue spruces along the property line to block 3B. With these trees in place there will be no need for screening shrubs. The shrubs would also screen less effectively as the proposed spruces. 31. [35.5.2(p) & 32.7.9.7] Provide information demonstrating how the dumpster will be screened. Labels for dumpster screening are now provided. 32. [35.5.2(p) & 32.7.9.8] It appears the majority of the tree canopy requirement is being met with existing trees; see above for direction on how to verify and document preservation of existing trees. The landscape plan is no longer counting the existing preserved landscaping as a contributor to the overall canopy requirement. Please see the revised calculations on sheet C6. 33. [35.5.2(p),32.7.9.8 & COD] The percentage of tree canopy required is determined by the gross residential density of the overall project. The maximum gross residential density for Blocks 1-5 is listed in the Code of Development as 8.1 dwelling units/acre, which would require 20%tree canopy. Revise the landscape notes to use 20% as the basis for the tree canopy requirement. The previously approved final site plan used a requirement factor of 20%which included this block 5 area. Since this site plan is only for Block 5 we are using a canopy requirement of 10% based on the higher density which proposes additional landscaping than what was previously approved. [35.5.2(p)] Show all utility lines and easements on the landscape plan to demonstrate no site conflicts exist. All utility lines and easements are now shown on the landscape plan. 34. [35.5.2(p) & COD Section IX] Section IX states that all plant species must conform to the Native Plants for Virginia Landscapes list. When species are provided, please select plants from this list. The proposed species shown have been confirmed to be native to Virginia. [35.5.2(t)] Show the limits of the Dam Break Inundation Zone. DCR has been contacted regarding review of this development; their reply will be forwarded once received. We've spoken with Rob Van Lier at DCR,who confirms that the South Fork Reservoir Dam is federally regulated, and the inundation zone regulations are not applicable to that dam. 35. [4.17] Lighting fixture B does not appear to be full cutoff; either select a different fixture or specify a different bulb that emits less than 3000 lumen. All lighting proposed on the lighting plan (sheet C7) is full cutoff per manufacture specifications. 36. [4.17] The catalog number provided for fixture B in the luminaire schedule does not match that provided on the cut-sheet; verify and revise. Fixture A and Fixture B use the same housing and bulb. The only difference is fixture B is 3 way mounted versus 2 way. The manufacturer cutsheet shown on sheet C7 is correct. 37. [4.17] List the tilt for Fixture A in the luminaire schedule. All proposed lighting shall not be tilted or aimed in a particular direction other than straight down.A note has been added as note#3 in the lighting notes on sheet C7. 38. [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 foot-candle. The standard lighting note has been added to the plan. 39. [Comment] ARB approval is required. ARB comments will be provided after the September 8th meeting. So noted. 40. [Comment] If any off-site easements are required, they must be approved and recorded prior to Site Plan approval. Among possible others, it appears an easement will be required for proposed grading in several areas of the County owned park parcel. Grading is no longer required in off-site areas. 41. [Comment] Clarify if an easement is being created for the new roof drain line coming on to the parcel. A new easement is now shown for the new roof drain line coming on to the parcel. Engineering Comments (Max Greene): 1. This project is within the FIRM 100 year flood plain [18-4.2.1, 18-5.1.28.a.2, 18-0.3.12]. Ordinance does not allow this type of flood plain disturbance. The flood plain will need to adjusted so the project is not the limits of the 100 year flood elevation. A CLOMAR [Conditional Letter of Map Revision] should be applied for, if one already exists, please submit a copy for review. The project has an ongoing grading permit to grade in the floodplain. We've submitted LOMA-F with the site plan submittal. Inspections Comments (Jay Schlothauer): 1. This building requires a fire sprinkler system. Indicate the arrangement, size and location of the fire line to the building. The fire line is now shown in the plan. 2. Provide a curb cut at the head of the striped access aisle for the barrier-free parking spaces. A CG-12 is now provided across from the accessible spaces. ARB (Margaret Maliszewski): Requirements: 1. A Certificate of Appropriateness is required prior to final site plan approval. So noted. 2. Include proposed architectural plans for review with the next submittal. Architectural plans have now been submitted and approved. 3. Indicate if rooftop mechanical equipment is proposed. If it is, clearly show how the building design fully screens the equipment from view. Notes are provided on the cover sheet regarding visibility of rooftop mechanical equipment. 4. Revise the proposed bollard fixture to one that is entirely full cutoff or one that uses an LED lamp. There are no bollards proposed with this revision of the lighting plan. Please see sheet C7. 5. Specify light pole height on the lighting plan, clearly indicating that the base (if one is proposed) is included in the total height. Total height(pole and base) should not exceed 20'. A note has been added to the lighting notes as note#2 on sheet C7 specifying the total height for all pole mounted fixtures. 6. Add the standard lighting note to the 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." The standard lighting note has been added to the plan. 7. Add a tree at the middle of the south side of the parking lot and a tree at the northwest corner of the parking lot. A tree has been added at the middle of the south side of the parking lot and another one has been added at the northwest corner of the parking lot. 8. Provide a complete landscape plan with all related details for review. A newly revised landscape plan is now shown with this resubmittal. See sheet C6. 9. Show the existing tree line, the tree line to remain, and tree protection fencing at the Block 5 perimeter. The existing treeline and new treeline are one and the same at this point of construction. No new disturbance to the existing treeline shall occur with this plan. Tree protection is still shown on the plan. Please see sheet C6. Conditions to be satisfied prior to issuance of a grading permit: 1. Show the existing tree line, the tree line to remain, and tree protection fencing at the Block 5 perimeter. The existing treeline and new treeline are one and the same at this point of construction. No new disturbance to the existing treeline shall occur with this plan. Tree protection is still shown on the plan. Please see sheet C6. Fire and Rescue Comments (Robbie Gilmer): 1. Proposed turn around on the north end of the structure shall be an approved fire access turn around. The current layout provides for a hammerhead movement for fire truck turnaround. The lane in front of the multi- family building is 26' wide, so a fire truck can pull in front of lots 12 and 13 and back into the parking lane in order to turn around. 2. Proposed turn around shall be marked"No Parking Fire Lane"per county code. "No Parking"signs are now specified at the proposed turn around. 3. Where the vertical distance between the grade plan and the highest roof surface exceeds 30', approved aerial fire apparatus access roads shall be provided. The parking lot shall have a 26' unobstructed travel lane for fire access near the building and a 20' clear unobstructed travel lane • • `r✓ .r • in the rest of the parking lot. Buildings over 30' require a 26' travel lane for ladder truck access and use. A 26' travel lane is now provided parallel to the building. 4. Proximity to building. At least one of the required access routes meeting this condition shall be located within a minimum of 15' and a maximum of 30' from the building. The side of the building on which the aerial fire apparatus access road is positioned shall be approved by the fire official. An access route is now provided at-20'from the building. 5. Please add a note for a Knox Box required, location subject to Fire Marshal approval during construction. A note stating that a Knox Box is required, location subject to Fire Marshal approval during construction, has been added to the plan. 6. FDC connection shall be on the address side of the structure, and within 100 ft of a fire hydrant. An FDC connection has been added to the address side of the structure within 100' of a fire hydrant. 7. Radii entering the parking lot shall not be less than 25'. Radii for the main entrance to the parking lot have been updated to be 25'. 8. Under ground detention located under parking lot needs to be able to support 82,000 lbs to accommodate aerial apparatus. A computation summary from the manufacturer of the underground detention has been attached. This shows the requirements and limitations of the system, and demonstrates that it will be able to support 82,000 lbs to accommodate aerial apparatus. ACSA Comments (Alex Morrison): 1. Submit 3 copies of the final site plan to the ACSA (Attn: Michael Vieira, PE) for construction review. The review is required to address the water service as well as site development over an existing sanitary sewer main. So noted. VDOT Comments (Shelly Plaster): 1. A signature on each sheet by a professional engineer is necessary or the plans should be clearly marked"Preliminary". So noted. 2. Trailside Court(Private) and Trailside Drive (Public) should be labeled. Trailside Court and Trailside Drive are now labelled. 3. The proposed ADT of block 5 should be proposed to ensure that they are in agreement with the previously approved road plans for Riverside Village. The proposed ADT is now listed on the cover sheet.
