Include reference to SDP2011-00047, Stonefield Building C1-IV Final Site Plan (WP02011-00055), dated June 20, 2011, approved 10/24/11, on sheet C-1. 2. Include reference to WP02011-00055, Stonefield Building C1-IV (SDP2011-00047), d. June 20, 2011, approved 4/12/12, on sheet C-1. 3. Revise C-1 Site Plan Note 2. Approved WPOs do not convey coverage to this proposed development. WP02011-00055 Plan Amendment Application is required. Please see FSP item 6., below. 4. Revise C-3 Stormwater Narrative, consistent with comments elsewhere. 5. Notes: a. WP02011-00055 Amendment approval is required prior to FSP Approval. b. (SWM Facility /Facility Access) Easement Plat recordation is required prior to WP02011-00055 Amendment approval. Applicant to provide Planning /Engineering circuit court deed bk.-pg. ref to recorded easement. Engineering will format deed of dedication of easement once plat review comments are addressed (once plat date of last revision is known). c. 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 WP02011-00055, then Albemarle requests deed bk.-pg. refto recorded Agreement with WP02011-00055 Amendment Application /submittal. For Final Site Plan Approval: 6. Submit VSMP Amendment Plan to WP02011-00055. Although WP02011-00055 is approved, site layout has changed. WW Associates prepared WP02011-00055 /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. b. Since claiming this is a grandfathered project, ref. /address conditions required for Grandfathering to guide review and approval, including 9VAC25-870-48.A. L(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 Engineering Review Comments Page 2 of 4 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. c. Revised storm sewer design computations. Also, see item 7., below. d. ESC Plan: show tree protection (TP) for trees that are to remain. e. SDP2011-00047, C-18 includes typ. ESC measure details required during parking lot construction. Provide ESC measures appropriate for parking lot demolition, and apartment construction. These may consist of IP, RWD, TS, SAF, etc. but prior -approved WPO does not consider current development, only past development. ESC plan is required with WP02011-00055 Amendment. f. SWPPP: Use county template; please also include: i. 2019 VPDES Permit Registration Statement ii. 2019 CGP Termination Form iii. 2019 CGP (26-pg.)

VSMP /WPO Plan Amendment Fee: $200 h. Approved Easement Plat for SWM Facilities (for final Amendment approval), including relocated Filterra unit/s and any additional on -site SWM: detention, for example, if required to qualify for Grandfathering. A separate Easement Plat Application with fee, as well as separate independent review of plat, is required. Please re£ county website, Planning documents. Tori Kanellopoulos may be a helpful resource guide. i. Additional information from WP02011-00055, including tables, civil details, ESC legend, SWM Plan data (Filterra unit/s [relocation /size]; VA SWMH, 1999, Vol. II, 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. 7. 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. 8. C 6: Show Ex. Filterra graphically to approx. true dimensions (Ex. Filterra, as shown, is —I' wide). 9. C=7: It is unclear how removing Ex. retaining wall and railing works with final grade or may compromise pedestrian safety. With Site Plan and WP02011-00055 Amendment, provide pedestrian safety relative to proposed grade, once retaining wall and railing are demolished along Inglewood Drive (C-7, C-8). 10. C7: Recommend provide replacement illumination for Ex. lampposts to be removed along Bond St. (X 2). Engineering defers to Planning. 11. C-9: Revise Pavement Section Detail to identify which travelways are covered (Bond, District, Inglewood). 12. C9: Provide typical civil details, including: inlet shaping, Nyoplast elements (grates, risers, pipes, etc.). 13. Provide LD-204, LD-229 for all inlets and storm pipes. Do not simply reference WP02011-00055, 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. 14. Provide drainage profiles. Label rim, INV MOUT, pipe material, slope, DIA, and length. Also, please see item 6.b., above. No increase in volume or rate of runoff. Engineering Review Comments Page 3 of 4 15. Ensure structure IDs are easily identifiable across plans (SDP201900057, WPO2011-0005, WP02011- 00055 Amendment). C-8: 16. Parking structure (internal to building): 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...) b. On this plan sheet (item, a.), provide a profile section view from ground to top of structure, with each deck /story of garage labelled to correspond with plan views (item a.). c. Ensure parking garage design meets each relevant or applicable 18-4.12.15 requirement. d. Provide posted garage speed, yield, ped-crossing, etc. signs throughout the structure, as needed, to help ensure pedestrian and vehicle safety, and to help minimize pedestrian -vehicle conflicts. e. Ensure garage entrance design meets 18-4.12.17.b. requirements for landing grade and sight distance (VDOT Standards apply). 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. 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: i. Relocate entrance 60'f, or as far as possible to the west. ii. Lengthen and widen exit throat to accommodate two lanes, left and right exit, to help limit queuing within the parking structure. iii. Provide a median space /pedestrian refuge (I-lanewidth) between left turn /rt. turn exits. 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.). 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. b. Consider alternative sidewalk /garage entrance -exit design/s. Offer improved pedestrian right-of-way and safety at garage entrance. 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. 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. Engineering Review Comments Page 4 of 4 i. Provide wall mount mirrors to provide view of sidewalk in both directions. Mount so useful at vehicle operator eye level. 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 pedestrians prior to proceeding to the next stop point, where operator obtains sight on Inglewood Drive. 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. 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 ht. (2.5 -3.0' ht., max., if possible). 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. 18. Label 2-way travel way width on Bond St. between Hyatt Place Hotel and semi -circular drop-off point in front of proposed Apartment building. 19. 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: htips://www.cbsl9news.com/content/news/Pedestrian-safety-at- Stonefield-39434110Lhtml. Engineering views safety a surmountable design challenge, and extremely relevant. Accident occurred in 2016 at District Ave. and Bond St. (Link) article above is worth reading. 20. If parallel spaces retained, revise design per VDOT Road Design Manual, Appendix B(1), pg. B(1)-59, Curb Extensions, Fig. below: i0 1513 Minimum 10' R Minimum 26 R Minimum Effective Radius 40' Minimum Curb Extension (Bulb -Out) 21. Show /label all roof leader lines. Show all roof storm collection points of connection with existing or proposed storm sewer. 22. Provide Note with offset distance, south face of building to sidewalk (0.0' if adjacent).
