High St. Charlottesville, VA 22902 Kelsey Schlein, PE [ kelsey& chimp -en ing eering com ] [ lustin(d�shimp-engineering.com ] Owner or rep.: 5t' Street Forest LLC / 250 W. Main St., Ste. 201 Charlottesville, VA 22902 [ kyle.redinger(i�gmail.com ] Plan received date: 31 Mar 2021 (Rev. 1) 21May 2021 Date of comments: 28 April 2021 (Rev. 1) 22 Jun 2021 [No objection; Note: SUB202100100 easement plat, review pending] Plan Coordinator: Andy Reitelbach Reviewer: John Anderson Comments below from Initial Site Plan. SDP2020-00066: with Applicant response for FSP Note: Engineering does not object to SDP2021-00022 approval, but notes that easement plat, SUB202 100 100, which shows multiple easements, may need to be recorded prior to ESP approval. Engineering accepts that public drainage easement may be recorded prior to departmental issuance of Certificate of Occupancy for the first structure in Block 5, which departs from typical approval sequencing. Engineering used this approach during WPO plan review /approval (public drainage easement recordation prior to issuance of first CO). Engineering defers to Planning whether option exists to allow ESP approval prior to easement plat recordation. L Cl1 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 WPO201800084. 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. (FSP) NA / WPO202000058 is approved (3/17/21) for ABC blocks 2-5, including off -site export /import from ABC (future development) block 1. 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). (FSP) May persist. Engineering defers to Planning/Zoning. Applicant response (3/22/21 letter): `We are working through a parking reduction request with Zoning.' With final site plan: 3. C5: Revise existing improvements shown on TMP 76-46C 1. See image below (C5 v. satellite imagoFy) [satellite imagery removed with FSP comments ] (FSP) Addressed. 4. CS C6 a. Label managed steep slopes. (FSP) Addressed. 5. C6 6. C7 Engineering Review Comments Page 2 of 7 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. (FSP) Addressed. Applicant: `Noted, this was addressed in approved WPO plan [WP0202000058], notes copied to SDP.' 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. (FSP) May persist (future). Applicant: `Noted, if necessary in the future, we will address this comment with the potential multifamily final site plan.' (Rev. 1) NA, block 5 Applicant response (5/18/21 letter): `Not Applicable for Block 5 FSP.' 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. (FSP) May persist (future). Applicant: `Noted, if necessary in the future, Pedestrian access will be provided with an internal sidewalk, to be addressed with the multifamily final site plan.' (Rev. 1) NA, Applicant response: `Not Applicable for Block 5 FSP.' c. Label site entrance radii and relevant entrance geometry. (FSP) Partially addressed. Applicant: `Site entrance radii and relevant entrance geometry are now labeled on the site plan sheet.' As follow-up: Proffered roundabout at intersection of Old Lynchburg Road and Fifth Street cannot be built with current ABC block 5 design. Revise block 5 entrance on Old Lynchburg (OL) Road to accommodate ZMA201900003 proffered future roundabout geometry. Images may be helpful. Sheet 2, SDP202100022 (per ZMA201900003) potential 150' inscribed diameter single -lane roundabout: Please compare —130' distance needed to construct slip lane to point of transition with OL Road RW, with sheet 6 —100' distance, Fifth St. to OL Road entrance. In other words, constructing the roundabout requires OL Road block 5 site entrance to be positioned farther north than shown.

DII -W -W, F DIP WATER LINE (Rev. 1) Addressed. Applicant: `You make a fair observation about the dimensions as compared to the roundabout exhibit, so we looked into this further and now have a few things to note: first, after further analysis of the roundabout exhibit, we realized that the exhibit roundabout location is not optimized and is not centered in the exisitng 5" St ROW. Second, we discussed this with Adam Moore of VDOT, who agreed that the design roundabout location will likely be further south (page down) than the exhibit shown. Finally, Adam agreed that the roundabout slip lane construction will need to have final design coordination with the new ABC entrance location, but has agreed to the entrance location as we have currently drawn. The idea is that the roundabout slip lane design will lead into a right -turn lane into ABC (where we currently have the right turn taper), ensuring a smooth transition into the site. On that note, we have revised the entrance layout per requests by VDOT to ensure this future transition. We realize thru this analysis that there will likely be more ROW dedication in block 2 than was estimated. We also realized that there is now no ROW dedication required for Block 5. Thank you for bringing this to our attention, for now we have completed entrance revisions to confirm that the location can work, so in the future we will simply need to coordinate final designs to ensure everything meets VDOT standards.' 7.

Please note that required sight distance for a 35-mph road is 390', while the required entrance spacing is 250'. Full 260' sight distance from entrance to intersections is achieved. Vehicles leaving from the proposed entrance will have adequate visibility of the Old Lynchburg intersection, allowing for safe movement out of the site.' Additional ESP review comments: 14. Note: Permeable concrete pavers at dynamic transport plaza do not constitute a required WPO plan design feature, and Engineering does not object to removal of permeable concrete pavers at this location. Please 15 Engineering Review Comments Page 7 of 7 ref WPO202000058 for approved SWM-related design (Note: WPO202000058 relies on an off -site pond, located at Fifth Street Place residential development, for SWM). (Rev. 1) Applicant: `Noted, these pavers are effectively a site aesthetic feature for which no WPO/VRRM treatment will be pursued. These will be installed per manufacturer specs, but do not count as a BMP and are not designed for runoff reduction. These pavers were promised on the rezoning application, and do need to be provided, so we will keep them.' C7: Provide storm runoff capture /conveyance for block 1 design at point runoff leaves 5.0% paved drive aisle; blue arrow, image, below: (Rev. 1) Addressed. Applicant: `to address potential erosion, and to achieve conveyance, we have shown a swale which will direct this runoff into Inlet A5. A5 will be a DI-3B inlet in the future, with the Block 4 expansion, but for now, we have this with a temporary grate top which will allow runoff into the structure. Inlet A5 has been always designed to receive this runoff. We have specified EC-3 matting within this swale as an additional precaution from erosion, and will work with the contractor to ensure proper stabilization occurs.'
