A Stormwater Facility Maintenance Agreement is required prior to final WP02011-00055 Amendment approval. Albemarle records Agreement for any new SWM Facilities, once executed. (Albemarle formats Agreement.) If there are no new SWM Facilities; that is, if only SWM are facilities shown on WPO2011-00055, then Albemarle requests deed bk.-pg. ref. to recorded Agreement with WPO2011-00055 Amendment Application /submittal. (FSP) Addressed. See 5.b., above. For Final Site Plan Approval: (FSP) Partially addressed /see below. WPO202000016 review is pending. 6. Submit VSMP Amendment Plan to WPO2011-00055. Although WPO2011-00055 is approved, site layout has changed. WW Associates prepared WPO2011-00055 /SDP2011-00047, so plan sheets and design data are likely readily available. At a minimum, please include the following with WPO Plan Amendment: a. (LOD) Limits of Disturbance. Ref. SDP C-15, DA Parking Area: Project Area =3.01 Ac. (FSP) Comment persists. As follow-up, revise WPO C-3 to include label /leader line indicating 2.66 Ac. disturbance. b. Since claiming this is a grandfathered project, ref. /address conditions required for Grandfathering to guide review and approval, including 9VAC25-870-48.A.1.(iv): `...has not been subsequently modified or amended in a manner resulting in an increase in the amount of phosphorus leaving each point of discharge, and such that there is no increase in the volume or rate of runoff' This means if apartment development runoff exceeds parking lot runoff, then on -site preliminary and modest detention may be required prior to discharge to overall Albemarle Place detention system installed beneath Costco parking lot. Design should provide and review will consider: points of discharge, amount /rates of storm release from D1, especially whether apartment development increases overall site imperviousness even slightly, which it appears may be the case. Please ref. 9VAC25-870-48, as well as SDP2011-00047, sheets C-15, -16 (Storm Sewer Design comps), etc. (FSP) Comment revised to request that WPO202000016 confirm any increase in rate of runoff or amount of phosphorus leaving SWM detention facility beneath Costco parking lot (easement shown on bk.-pg. 4135-223). c.

Additional information from WP02011-00055, including tables, civil details, ESC legend, SWM Plan data (Filterra unit/s [relocation /size]; VA SWMH, 1999, Vol. I1, Appendix 5D Worksheets [revise, as needed; ref. SDP2011-00047, C-23]), including ref. to approved WPOs, to prepare a comprehensive standalone Amendment to WP02011-00055. (FSP) Comment persists. For example: WP0202000016, C7, Stormwater Narrative relies on biofilter `installed as part of the Stonefield Blvd Road Plan (WP0201100036).' WP02011-00036 (C-22) shows a biofilter at present-day Int. of District and Houston. Please provide an As -built drawing comparing as -built condition of this biofilter against design (WP0201100036, C-22). Note: WP0201100036, C-22, calculations provide that load removed by biofilter (C-22) = 5.26 X 0.65=3.42lbs. If later WPO or WPO Amendment revised biofilter design to provide WP0202000016 C=7 pollutant removal of 9.69 lb, reference WPO# on SDP202000024 and WP0202000016. Also, please revise WP0202000016 C7 text /calculations (Narrative), consistent with as -built condition of Houston - District biofilter, and approved SDP /WPOs, including biofilter landscaping (as -built v. design).

Evaluate existing storm sewer pipes for capacity, since existing conveyance was designed for parking lot, while configuration (and possibly amount /rate) of runoff reaching existing inlets and pipes is modified with proposed apartment development. (FSP) Addressed. C-12. Also: item 24, below. 8. C 6: Show Ex. Filterra graphically to approx. true dimensions (Ex. Filterra, as shown, is —P wide). (FSP) Addressed. 9. C7: It is unclear how removing Ex. retaining wall and railing works with final grade or may compromise pedestrian safety. With Site Plan and WPO2011-00055 Amendment, provide pedestrian safety relative to proposed grade, once retaining wall and railing are demolished along Inglewood Drive (C-7, C-8). (FSP) Engineering Review Comments Page 6 of 9 Comment persists. Copy text note from WP0202000016, C-3, to SDP202000024, C7, Demolition Plan: `Contractor shall provide shoring to protect embankment as retaining wall is removed. Contractor shall provide shoring plans to [ design] Engineer for approval.' [WW Associates, EOR] 10. C7: Recommend provide replacement illumination for Ex. lampposts to be removed along Bond St. (x 2). Engineering defers to Planning. (FSP) Withdrawn. Engineering assumes adequate lighting at apartment main entrance on Bond Street. 11. C-9: Revise Pavement Section Detail to identify which travelways are covered (Bond, District, Inglewood). (FSP) Addressed. C-10 pavement demolition and parking areas pavement section details appear adequate. 12. C-9: Provide typical civil details, including: inlet shaping, Nyoplast elements (grates, risers, pipes, etc.). (FSP) Addressed. Also: Item 25, below. 13. Provide LD-204, LD-229 for all inlets and storm pipes. Do not simply reference W002011-00055, but transfer table data from WP02011-00055 to this site plan, and to WPO Plan Amendment. Report values that correspond with design for proposed apartment development. These values will differ from initial WP02011-00055 LD-204 /LD-229 table values, in some instances. (FSP) Addressed. Request for revised inlet table (LD-204) withdrawn since roof leader line direct connection with storm sewer accounts for most post -developed site runoff reaching the storm system. 14. Provide drainage profiles. Label rim, INV IN/OUT, pipe material, slope, DIA, and length. Also, please see item 6.b., above. No increase in volume or rate of runoff. (FSP) Addressed. Also: Item 24, below. 15. Ensure structure IDs ai Zsily identifiable across plans (SDP201900057, WP02011-0005, WP020I1- 00055 Amendment` (FSP) Addressed. C-8: 16. Parking structure (internal to building): (Note: As follow-up to 12/6/19 Engineering -Applicant meeting (Engineering absent from 12/5/19 SRC), Engineering defers to building inspections on virtually all parking garage interior configuration concerns, and related ISP parking garage -related comments.) a. Provide a series of 6-7 parking plan views, one per story. Recommend all levels of parking garage be displayed on a single site plan sheet with each plan view clearly labeled (Story G, 1, 2, 3...) (FSP) Addressed (sheet AP -I). As follow-up, please see item 23, below. b. On this plan sheet (item, a.), provide a profile section view ti-om ground to top of structure, with each deck /story of garage labelled to correspond with plan views (item a.). (FSP) Addressed. Request for cutaway profile section withdrawn. c. Ensure parking garage do -it or applicable 18-4.12.15 requirement. (FSP) Addressed. 18-4.12.15 does not apply to parking garages. d. Provide posted garage spc_ -Id, ped-cross. throughout the structure, as needed, to help ensure pedestrian and vehicle safety, and to help minimize pedestrian -vehicle conflicts. (FSP) Withdrawn. e. Ensure garage entrance design meets 18-4.12.17.b. requirements for landing grade and sight distance (VDOT Standards apply). (FSP) Withdrawn. Also, 16.c., above. f. Ensure max. grade for parking spaces and access aisles abutting parking spaces does not exceed five (5) percent. Ref. 18-4.12.15.c. Label access aisle grade on each plan view of garage, each floor of garage structure. (FSP) Withdrawn /review error. Max. grade for parking garage ramps =6.67%. Also: Item 23, below. g. At 1556 VDP (vehicle per day), in the interest of pedestrian safety, improved sight distance, and to limit queuing on Inglewood Drive (predictable with collocated entrance /exit), queuing within structure near or beyond gates, Engineering recommends design separate garage entrance /exit. Recommendations: (FSP) Items discussed with Applicant at 12/6/19 meeting. Items i.-iii. below are recommendations (FSP not required to reflect i.-iii. recommendations). Item iv. is revised to request specific and non-specific design response, including revision. Please call if any questions. i. Relocate entrance 60'±, or as far as possible to the west. (FSP) Withdrawn (infeasible). ii. Lengthen and widen exit throat to accommodate two lanes, left and right exit, to help limit queuing within the parking structure. (FSP) Addressed. Engineering Review Comments Page 7 of 9 iii. Provide a median space /pedestrian refuge (I-lanewidth) between left turn /rt. turn exits. (FSP) Withdrawn (infeasible). iv. Revise pedestrian crossing by whatever means necessary to ensure pedestrian right-of- way at entrance /exit points (calming, raised sidewalk, exit lane separation, mirrors, sidewalk -building offset, etc.). (FSP) As follow-up: Provide a detail to clearly indicate crosswalk v. garage exit profile: raised v. level grade. Also: indicate pedestrian crosswalk pavement markings at garage entry /exit, if any. a. Note sight distance lines place vehicle (operator) `eye' on sidewalk, meaning vehicle is assumed to stop on sidewalk prior to exiting. This design cannot be approved. If vehicles must stop at this point, then pedestrians are routinely prevented from safely crossing entrance /exit point. One car after another will proceed to this point, and block the sidewalk. Potential pedestrian -vehicle conflicts are unacceptably high, not intentionally yet unavoidably, by design. (FSP) Persists. Ref. item 26, below, which requests revision. b. Consider alternative sidewalk /garage entrance -exit design/s. Offer improved pedestrian right-of-way and safety at garage entrance. (FSP) Comment persists without request for specific revision. c. City of Charlottesville developments along Main Street (The Standard) and Roosevelt Brown Blvd (The Uncommon) and pending new towns and apartments near the downtown mall on Main Street offer little by way of design to alleviate pedestrian -vehicle conflicts as vehicles exit these developments, virtually blind. (FSP) As follow-up: An incorrect statement: The Standard offers mirrors and columns at entry /exit which allow drivers to see pedestrians, and to see farther more easily. Engineering requests mirrors for this apartment development project. Also, 16.g.iv.i., below. d. Albemarle intends to minimize risk to pedestrians first, vehicles second. e. Pedestrian safety is paramount. Vehicle operator inconvenience /exit wait times are a secondary concern. f. Proposed design provides vehicle operators negligible to no sight of pedestrians approaching garage entry /exit, which is at edge of the building. Sidewalk also touches building exterior. g. Design assumes vehicles will proceed to walk, stop on walk, then exit onto Inglewood. h. At a minimum, provide multiple signs /warnings of pedestrian crossing, including: SLOW, YIELD, Ped. Crossing using typ. and standard VDOT icons, with typ. VDOT striping on sidewalk to indicate pedestrians have right-of-way. (FSP) Withdrawn. 12/6/19 meeting provided informed understanding of limits of review, relative to garage interior. During meeting, Applicant explained adequate posted guide indicators will be placed inside the parking garage. i. Provide wall mount mirrors to provide view of sidewalk in both directions. Mount so useful at vehicle operator eye level. (FSP) Comment persists. j. Provide a STOP sign inside the parking garage, prior to sidewalk, so a vehicle must come to a complete stop and yield to possibly unseen pedestrian/s prior to proceeding to the next stop point, where operator obtains sight on Inglewood Drive. (FSP) Withdrawn. Also, 16. .ig v.h., above. k. Safety is the paramount design consideration. A visit to the The Standard (Main Street /C'ville) may be instructive, or helpful, since designs are so similar. (FSP) Also, item 16,g iv.c., above. 1. Architectural design may provide enhanced pedestrian safety via an `open' wall /column design. Recommend an open ground -level North building face with an unrestricted view between columns, with minimal parapet wall lat. (2.5 -3.0' ht., max., if possible). (FSP) Comment persists. Also, item 16,g iv.c., above. Engineering Review Comments Page 8 of 9 17. CG-12 ramps at parking garage entrance /exit: Provide landing prior to point sidewalk and entrance /exit intersect. That is: do not have sloped CG-12 ramp ending at point entrance /exit intersect ramp, to help prevent rollaway incident at what is a blind intersection. It may be better to ensure at -grade walk, with ramps for vehicles. Pedestrians take priority over vehicle operator convenience. Please ref. VDOT Road Design Manual, Appendix B(1), pg. B(1)-52, Fig. 12 (Traffic calming details /Raised Crosswalk. (FSP) Comment persists. Also: Item 26, below. 18. Label 2- . _ivci 3ond St. between Hyatt Place Hotel and semi -circular drop-off point in front of proposed Apartment building. (FSP) Addressed. C=8 lists ref. to D.B. 4135-249 23' ingress /egress easement. 19 20 Given obstructed sight view for vehicles exiting garage and abiding pedestrian concern, eliminate three parallel parking spaces west of exit and two parallel spaces east of exit. Push sidewalk away from building face and provide vehicle operators exiting both opportunity to see pedestrians, and to see oncoming traffic before pulling onto Inglewood. Planning may consider any waiver required, in interest of pedestrian and vehicle operator safety. Note: a tragic pedestrian fatality occurred in 2016 within tight design confines of Stonefield Town Center. Article at: https://www.cbsl9news.com/content/news/Pedestrian-safety-at- Stonefield-394341 IOI .html. Engineering views safety a surmountable design challenge, and extremely relevant. Accident occuffed in 2016 at District Ave. and Bond St. (Link) article above is worth reading. (FSP) Partially addressed. As follow-up: Provide pavement markings to delineate parallel spaces that remain. No request to remove remaining parallel parking spaces SW of parking garage entrance, C=8.

AP-1 Parking Garage Layout provides no dimensions. Recommend provide parking space and drive aisle widths. Engineering Review Comments Page 9 of 9 Recommend, for example, labels to indicate ramp slope < 6.67% max. grade allowed for parking garage ramps. J. Gorman email to Engineering, December 6, 2019 10:03 AM, is helpful, and includes this text: ` Section 406.4.4 Ramps Vehicle ramps shall not be considered as required exits unless pedestrian facilities are provided. Vehicle ramps that are utilized for vertical circulation as well as for parking shall not exceed a slope of]: 15 (6.67 percent).' 24. C-12: Storm profile 46 thru 46.8 shows 18" HDPE downstream of 24" DIA pipe. Increase receiving pipe diameter. 25. C-10: Two civil details are oblique /images distorted (CG-6, MH frame and cover). Please revise. 26. C=8: Provide inset detail showing sight distance line (eye /object) if typ. passenger sedan stops without breaking plane of the sidewalk. Provide detail showing how far a driver exiting the parking garage can see before vehicle begins to break plane of edge of sidewalk. At garage exit, pedestrians, not vehicles, have right-of-way.
