For Final Site Plan approval: 1. C2.0 a. Please provide deed bk.-pg. ref for existing public drainage easement for storm conveyance leaving the Guadalajara property to the south, then transiting hotel development parcel. b. Show and label managed steep slopes. c. Revise label reading `Use: vacant, TAP 78-1 P since it is a commercial car sales parking lot with non -vacant use (blue -circle area, image, below). d. Please consider and provide collection/conveyance (as needed) of storm runoff that may transit existing drainage ditch that crosses the hotel site, a ditch beginning near the car sales parking lot (blue arrow, below): Engineering Review Comments Page 2 of 4 e. Show Aabel existing sidewalk adjacent to Town and Country Lane. Determine and label ex. sidewalk width. f. Plan appears to propose elimination of this sidewalk, preserve walk as a required element of public streets per subdivision street design guide, VDOT Road Design Manual, Appx. B(1). 2. C4.0 a. Please revise label reading `retaining wall with fall protection barrier on top for vehicles and pedestrians' to `retaining wall with guardrail' since guardrail is appropriate for vehicles. VDOT GR-2 standard is available to include on plans. b. Provide wheel stops for parking spaces fronting retaining wall. c. Label narrowest width of curvilinear parking spaces in sections that do not label width at narrowest dimension. d. Revise parking space -sidewalk design, select from allowable parking -sidewalk configurations at p. 17, ACDSM, which requires, for example, wheel stops for 18' L spaces w/ 5' w sidewalks (https://www.albemarle.orgJHome/ShowDocument?id=270 ). e. Identify curb type/s. f. Label all sidewalk widths. g. Provide HC-parking space signs. Engineering Review Comments Page 3 of 4 h. East entrance to hotel may limit fire rescue (apparatus) access to site. i. Engineering defers to ACFR. ii. If ACFR requests site access to include unrestricted access around the hotel, ensure retaining wall design accommodates ACFR vehicle weight (65,000 - 80,0001b.), or weight of vehicle class likely to respond from ACFR Station 16, Pantops. iii. If ACFR apparatus requires access around hotel, ensure retaining wall guardrail accommodates overhang portion of ACFR vehicle, from front axle to front fender. iv. (Please do not assume ACFR vehicles are permitted to stage vehicles or response or presence within public RW of Town and Country Lane, or Olympia Drive.) i. Provide GR-2 with labels for retaining wall located along linear and curvilinear parking along N edge of hotel parking lot. j. Increase 3' sidewalk width along Olympia Drive to meet VDOT minimum sidewalk width, 5'. [See VDOT Road Design Manual, Appx. B(1), Sec. 41 LAM - httos://www.virginiadot.orli/business/resources/LocDes/RDM/AooendBl.udf ] k. Provide CG-12 at E end of proposed sidewalk adjacent to Olympia Drive, W side of entrance to hotel site. 1. Provide GR-2 detail. in. Submit geotechnical PE -sealed retaining wall design for all wall ht. >4-ft. for Engineering review prior to FSP approval n. Note: All walls >3-ft. ht. not integral to building design will require building permit from building inspections, CDD. 3. C5.0 a. Convert parking space with SWM facility manway access to a parking island so that manway access is not obstructed by a parked vehicle. b. Provide drainage profiles (storm pipes, UG SWM detention facility). c. Show /label a public drainage easement extending from UG detention system (SWM easement) that is centered on the facility outfall pipe, OF, to the property boundary. d. Provide detail for relieving arch or pipe sleeve where UG SWM facility outfall pipe, OF, is proposed to pass beneath retaining wall near Olympia Drive. Consider and discuss alternatives, or if no alternative SWM facility outfall location exists, establish this via notes, labels, etc. e. It is not possible without SWM detention profile to evaluate proposed SWM facility easement with precision. As design advances, please consult ACDSM, p. 15, Easement diagram to determine required SWM facility easement width. EASEMENT WIDTH. M-METER. 2'. ] ill 5'1. 10' d0' )IN.) Engineering Review Comments Page 4 of 4 f. Provide VDOT LD-204 inlet computations. Provide LD-229 storm drain design computations. g. Proposed retaining walls are shown within existing public drainage easement, existing storm pipes are shown crossing beneath or intersecting proposed retaining wall. Provide final site plan that indicates existing storm drain pipes are relocated to avoid any construction or future maintenance conflict with retaining walls. No permanent improvements of type proposed are allowed within public drainage easement. h. Establish new public drainage easement centered on relocated existing storm drain lines. i. Record new platted public drainage and SWM facility/access easements prior to WPO plan approval. j. Note: WPO plan approval is a prerequisite to FSP approval. k. Furnish relevant design data with WPO, including weir plate, manway, weir orifice design, debris cage, typ. details, plan/profile, etc., as needed. 1. Avoid nuisance ponding at all locations across parking lots /across site access. Main entrance to hotel appears somewhat susceptible to nuisance ponding /ice in winter. in. Ensure parking lot grade near S entrance to hotel is <_ 5%, -5.25% impermissible. [18-4.12.15.c.] n. Ensure slope, S entrance to hotel is <_10% in every direction. [18-4.12.17.a ] o. Revise grade, S entrance to hotel such that side -slope is traversable for tall (high -clearance) trucks, side -slope is severe at this location posing risk of tipping /loss of control in wet or icy conditions. p. Provide /label CG-6 wherever runoff concentrates against curbing, for example: loop around west end of hotel. q. Recommend YD-inlet above /connecting with storm pipe 64 at east end of hotel. r. Show /label CG-12 at HC-parking spaces at front of hotel. s. Label parking lot island bullnose radii (or typ. R). t. Please ensure each building egress is ADA-compliant with respect to landing, max. grade, etc. u. Collect /convey retaining wall weep discharge via system to prevents water crossing sidewalk/s. v. Acquire /record off -site temporary construction easement to perform grading on TMP 07800-00- 00-009CO3 or provide copy of written agreement to perform grading across or at edge of this parcel. Proposed site contours are infeasible without easement /Agreement from this TMP owner. 4. Submit a WPO plan for hotel development at earliest convenience. 5. Submit separate easement plat for public drainage and SWM facilities associated with this development. Separate plat review process must be completed, plat approved and recorded, prior to WPO plan approval. 6. L1.0 a. Five canopy species (landscape plants) proposed along base of =W wall have strong potential to undermine wall, revise landscape plan. b. Restore, show, label, and dimension 5' sidewalk (Min. width) along both Town and Country Lane and Olympia Drive since removing /not replacing an existing pedestrian facility within public RW is not an option.
