High St. Charlottesville, VA 22902 Kelsey Schlein, PE [ kelsev(d�shimo-engineeringxom ] [ iustin(a),shimo-engineering.com ] Owner or rep.: 511 Street Forest LLC / 250 W. Main St., Ste. 201 Charlottesville, VA 22902 [ kyle.redinaer(i�gmail.com ] Plan received date: 26 Oct 2020 Date of comments: 23 Nov 2020 [ rev. 3 Dec 2020 ] Plan Coordinator: Andy Reitelbach Reviewer: John Anderson SDP2020-00066 1. C 11 Stormwater Management Notes: Please ref. WPO201800084, Royal Fern Phase 2 rather than a regional stormwater facility (in addition to referencing more recent ZMA201900003). Engineering will evaluate WPO plan for Albemarle Business Campus WPO plan against information and stormwater data approved with WP0201800084. WPO plan approval for ABC is not automatic with ZMA201900003 approval or satisfied by reference to regional stormwater facilities for blocks 2-5. WPO plan approval is required for ABC FSP approval. This development is subject to same or similar SWM program review requirements and criteria as applied to WPO201800084. Also, see Engineering email to Shimp Engineering, 11/12/2020 2:56 PM, and November 12, 2020 12:04 PM. Please submit WPO plan for ABC at earliest convenience. 2. It appears that design relies on fewer parking spaces than required by ordinance. There is potential for ISP disapproval with significant revision required prior even to approval of ISP (with conditions). With final site plan: 3. C5: Revise existing improvements shown on TMP 76-46C1. See image below (C5 v. satellite imagery) Engineering Review Comments Page 2 of 4 4. C5C6 a. Label managed steep slopes. 5. C6 a. Existing grade appears to indicate a SWM facility in vicinity of feature labeled rip -rap. With WPO, address any SWM quality -quantity implications of removing any existing SWM facility with proposed development. 6. C7 a. Recommend provide sidewalk access to westernmost 24-apt 3-story building via internal sidewalk rather than walk within public RW along Country Green Road since this is facility to be used by residents for every trip between vehicle and apartment. This route so near a public road provides inherent risk, risk analogous to requiring owners of single-family dwellings to transit walk within public RW to travel between parked car in driveway and dwelling entrance. b. If apartment building access is via sidewalk along Country Green Road and ordinance requires illumination from parking to dwelling entrance, provide adequate lighting. Engineering defers to Planning, while reiterating safety concerns for residents if forced to rely on a walk within public RW of Country Green Road. c. Label site entrance radii and relevant entrance geometry. 7. C7 C8C8 a. Label (typ.) parking space length. b. Label parking lot island radii. c. Provide, label and revise or reconfigure parking to provide adequate HC parking, with ramps. d. Label CG-12. e. Label CG-6. f. Provide /show Aabel dumpster pads for each use. No use appears likely able to function without permanent outdoor solid waste disposal, with possible exception of self -storage, yet self -storage patrons may wish to avail themselves of trash facility, which may or may not be required. Hotel, office, and retail space typically (likely) require dumpster pads. Engineering defers to Planning. 8. C8 Engineering Review Comments Page 3 of 4 g. Please ensure that all parking spaces immediately adjacent to sidewalks are either: i. 18' L fronting 6' sidewalks, or ii. 18' L with bumper blocks fronting 5' sidewalks (ref. ACDSM, pg. 17). a. Label block 2-5 development entrance radii /relevant entrance geometry at Old Lynchburg Road. b. Label angle for angled parking. c. Provide angled parking dimensions for comparison with ordinance requirements /ACDSM. d. Label site features (walks, crosswalks, traffic control signs). e. Provide internal and external stop /yield signs to define stop /thru traffic patterns. f. Since site access from 51' Street spans property line with parcel to east, provide legal instrument that allows site access. Existing legal instrument (201800013730) presents obsolete image. Provide instrument specific to current geometric design of Wahoo Way. PwmW�6 6-5 Zplm_ 6] owu. cua. uc e 9lGW PAW$ I/YS 06 �n PG Pc 2m Flr�. SI fXi, 234 n. g. Provide /show /label hotel loading space. h. Clarify via label /dimension the short arc -pedestrian facility at intersection Wahoo Way and 5'h St. to clearly define how 10' multi -use path along 5' St. connects with 5' walk along Wahoo Way. 9. C9: Label island dimensions and curb radii at right -in /right -out entrance on Old Lynchburg Road. 10. C10 a. Provide spot grading near islands to ensure runoff reaches inlets without nuisance ponding. b. Clarify how proposed UG detention and inlet conveyance system discharge to existing SWM infrastructure. If discharge is via storm pipe between the two 28-apt buildings to property to the immediate west, with WPO show compliance with channel and flood protection at this discharge point. c. Provide flowlines that clarify direction of flow in storm pipes. Engineering Review Comments Page 4 of 4 d. Label underground detention system. IL C10.C11 a. Show Aabel proposed utility easements. i. Recommend label private drainage easements. ii. Label public drainage easement downstream of proposed SWM facility. iii. Public SWM facility and public drainage easements require plat with deed, and recordation prior to FSP approval. iv. Acquire and reference recorded public drainage easement across TMP 76-46C1 (Mountainwood Properties) that receives ABC development runoff. v. Ensure post -developed storm runoff across TMP 76-46C 1 is non -erosive. b. Ensure easement widths are consistent with easement width diagram, p. 15, ACDSM. c. Indicate any existing trees to be preserved. 12. C11 a. Apparent ponding at N comer of block 2 hotel parking lot: Revise to eliminate nuisance ponding. b. Apparent ponding at N comer of block 3 office parking lot. Revise to eliminate nuisance ponding. c. Apparent ponding at N comer of 6,000 SF retail parking lot. Revise to eliminate nuisance ponding. d. Provide spot grading throughout to ensure runoff reaches inlets, without nuisance ponding. e. Wherever grades concentrate runoff against curbing, revise proposed CG-2 to CG-6 [ref. 18- 4.12.15.g J. f. Provide additional proposed grade labels, for example: i. Graded slope area N of hotel parking lot, ii. Hotel parking lot, and, iii. Impervious paved areas N of self -storage. g. Retaining walls >3' ht. require a building permit. Retaining walls >4' ht. require sealed design (PE) plans. Retaining wall design review by Engineering is required prior to FSP approval. h. Provide wall elevation details for retaining wall at W end of self -storage. 13. C 12: Provide horizontal sight distance that avoids landscape /sight line conflicts.
