C0.0 Note reading There are no critical slopes located within the project to read, `No steep slopes are affected by this project,' if that is the case. Preserved and managed steep slopes exist on this parcel, which is in the development area, and should be shown on CO.1. 2. Show managed steep slopes, C2.0. Ref. county GIS. 3. Recommend ref. WP0201900021, UVA Research Park Loop Road VSMP Plan, on C0.0. 4. Include public road acceptance procedure on C1.0.

Provide pavement section with base stone, base asphalt and asphalt surface depth (dimension) labeled. 9. Provide, show, and label VDOT standard barricades at turnout locations on west side of loop road (points of future connection /Encompass). A barricade is not required at 90-deg right angle in road, but at Encompass southern /northern entrances where proposed grades slope away. If these turnouts will not receive roadway extension within 12 months, provide GR-2 to limit damage or injury that may reasonably attend a loss of control incident at either location. Please provide barricade and GR-2 typ. details. 10. Ensure SWM-related details (trash rack for SWM drainage structures and Contech ® Jellyfish Filter), C1.2, appear with WP0201900021 VSMP /WPO plans, as well. C2.0 11. Recommend provide label ref. to SUB201800171, Lewis and Clark Drive Road Ext. RP, similar to label ref. to UVA Research Park Sewer Extension project. 12.

Provide street name sign, even if unnamed, or name pending. 15. Provide complete horizontaldata . plan • radius of Engineering Review Comments Page 3 of 4 16. Provide speed limit signs. 17. Please clarify `Future private R/W (Typ.)' label. Is Loop Road a proposed private street? If so, private streets may not intersect a public road at more than one location. If this is a loop road, it will likely intersect Lewis and Clark Drive (public road) at more than one location, and must itself be a public road. 18. If Loop Road is a proposed private street, please ref. Ch. 14 for private street request procedure. 19. C4.0 /C4.1: Recommend `Ped-crossing Ahead' signs for Loop Road in advance of crosswalks. 20. Recommend caution sign on Loop Road prior to Innovation /Lewis and Clark that notifies `Emergency Fire /Rescue Entrance Ahead.' C5.0: 21. Show proposed SWM Facility / Access /Drainage Easements. 22. Provide curb break /mountable curb to provide SWM Facility Access (ACDSM, pg. 12). Provide access label or note on plan and linework with proposed grading that meets ACDSM standard, text image, below, for dry pond Access: Best Management Practices for Stormwater Management: All practices must have adequate vehicle access; 10' width graded at less than 20%. Anything over 20% must be surfaced with gravel or pavement. Access must be to all structures and forebay cleanout areas. Easements must be provided over all access and facilities, to accompany deeds and agreements as available on the county website; http://www.albemarle.orv-/deptforms.asp?department--cdenizwno 23. Provide typ. detail, transition from CG-6 to mountable (rolltop) curb at point of SWM facility access. C4.1 24. The same line is labeled 67' wide R/W and Future Private R/W. Please see item 17. Clarify. 25. Provide `No Parking' signs at regular intervals, since no on -street parking. 26. 10' wide utility corridor may be sufficient to install utilities if water /sewer are located within roadway prism, as proposed, but wider utility corridor/s may be required if VDOT policy requires san./water utility lines to relocate outside the roadway prism. Note, for example, ACSA minimum horizontal separation for water and sanitary sewer facilities. 27. Provide plan note outlining sequence of removal for Ex. septic field, and that references any VDH permit number, or permit requirements that may guide construction in vicinity of area marked `Approximate Location of Ex. septic Field per plans...' 28. C4.2 shows proposed 8" PVC (SSWR) passing beneath multiple storm pipes. Please consider recent VDOT Culpeper bridge and drainage guidance concerning utilities placed over or under structures to be maintained by VDOT, and coordinate with VDOT to revise design as needed. 29. C4.3 shows proposed 8" water line passing beneath multiple storm pipes. Please consider recent VDOT Culpeper District guidance concerning utilities placed over or under structures to be maintained by VDOT, and coordinate with VDOT to revise design as needed. C5.0: 30. Ensure dry pond design details on RP match design details on WPO201900021, or preferably limit design detail provided for dry pond on the Road Plan to conceptual outline, with ref. to WP0201900021. 31.

C5.3: Provide cross drains per road plan checklist for reviewers, pg. 4 (`locations shown and labeled with VDOT designations (CD-1,2) at every major cut and fill transition or sag curve'). Design appears to require eight (8) cross -drains (2 sag curves, 6 cut/fill transitions). 35. C6.0, C6.1: Remove from Road Plan. Include with VSMP /WPO Plan. Review comments for these plan sheets will be included with WPO plan review comments. C7.0 36. Provide 95% compaction note for area of fill at Str. 112, profile Str 112 — Str 100. 37.
