After further discussion with Planning Division, Engineering review comments are revised. SUB2018-00145 2. Show and label critical slopes on plat. Ref. Exhibit. (Rev. 1) Addressed. 3. Show and label stream buffers not shown. Ref. Exhibit. (Rev. 1) Addressed. 4. Note 2: Provide date of (current) field survey. (Rev. 1) Addressed. 5. Provide tie for farm road centerline at 800.39' residue boundary line. (Rev. 1) Addressed. 6. For L3 + 442.59 segment, provide total length in parenthesis (514.59'). (Rev. 1) Comment withdrawn. Review error: total distance—442.59'. 7. For 3.0 Ac. parcel boundary north of proposed drain field, show 354.56 as total length, if such is the case. (Rev. 1) Comment withdrawn. 8. For 362.00' boundary of 3 Ac. parcel, list bearing with /at distance label (N35°07'05"E). (Rev. 1) Addressed. 9. For L10 tie (which is L5), provide (TIE) label with L5. (Rev. 1) Addressed. 10. Recommend stream buffers be shown as dot -dash line type, not solid line. (Rev. 1) Addressed. i i. deleted i 0/24 ii 8 (review o eF) n a/b. deleted 10/24/18 12. Shift L7 label so it is not obscured by residue boundary line. (Rev. 1) Addressed. 13. Provide bearing/distance or curve data for farm road centerline between C5 and C6. (Rev. 1) Addressed. 14. New: Code 14-412.A.2 applies. With subdivision, Barracks Farm Road, a private road, will serve 5 parcels/lots: TMPs: 44-22 (residue); 44-22B; 44-22C; 44-22C1; 44-22D (ref. image, below), and three lots over ^ distance of 2,714'{EL).—Provide a PE seale drawing to confirm a private street constructed to standards listed at 14-412.A.2. exists this dirt^^^e, between end state maintenance and a point 150' beyond entrance to parcel 44-22D, prior to subdivision plat approval. Standards include: Engineering Review Comments Page 2 of 3 1. A turnaround meeting AASHTO guideline, required at a point just beyond 518 / 516 Barracks Farm Road driveway (a shared driveway appears to serve 518 and 516). (5 Feb, REVISED) Comment withdrawn. Existing intersections internal to TMP #44-22 (Residue) provide adequate turnaround. Current roadway evaluated adequate to ACF&R needs, ref. review comment (1/22/19; CV): "The driving surface up to the development site is wider than shown on the plans and sufficient for emergency vehicle access. Fire Rescue has no objection to this lot being developed but any further development on this road will require upgrades in width and surface." 2. Vertical centerline curvature meets a minimum design K value of five (5) for crest curves and fifteen (15) for sag curves (provide street profile /K-values). (5 Feb, rev.) Comment withdrawn. GIS terrain contours indicate road meets vertical centerline curvature minimum design K values for crest /sag curves. 3. Street easement is thirty (30) feet, minimum. (5 Feb, rev.) As follow-up: Please dimension access easement width on TMP #44-27D. (Rev. 2) Addressed. 4. Radius of horizontal curvature is forty (40) feet or greater. (5 Feb, rev.) Comment withdrawn. GIS terrain contours indicate road meets horizontal curvature, forty (40) feet or greater. GIS49age(ver-tisal�%ntal geo netf�) (Rev. 2) Addressed. GIS image deleted. 5. Travelway width is fourteen (14) feet, minimum. (5 Feb, rev.) Asefollow-up: Requirement applies at property entrance, at pillars. Ref. 14-412(A)2(a). Where additional width is required, compacted VDOT 2 1 A stone, 6"-8" depth may be placed, and compacted with sheepsfoot roller or similar equipment to match existing asphalt grade and cross slope, including at pillars, between end state maintenance exterior to TMP 44-22 (Residue) and a short distance interior to the parcel. Applicant -furnished field measurements on 31- Jan 2019 indicate roadway width is at least 14' near end state maintenance but is 12'-8" at pillars and is again >14' wide at a point 45' interior to the parcel. Once required minimum 14' width is constructed at points currently less than 14' wide, and shoulders are established (next item, item #6), submit written notification to Albemarle County /Engineering Division that roadway improvements are complete. Engineering will inspect to confirm. Roadway improvements must be built or bonded prior to subdivision plat approval. (Rev. 2) In process. It is Engineering's understanding roadway improvements will be bonded (bond estimate request received 2/25/19); improvements to be built with later site construction. Plat may not be approved until bond is posted. 6. Three (3) foot minimum shoulder width. (5 Feb, rev.) As follow-up: Requirement applies at property entrance, even at pillars. Establish 3' shoulder width, minimum. Minimum travelway plus minimum shoulder width requires a minimum twenty (20) foot opening between pillars. A pillar must be relocated. Also, ensure shoulder cross slope adequate to avoid stormwater detention at the pavement edge, for entire length of roadway, from end state maintenance to 150' past proposed entrance to parcel 44-22D. Image below, pg. n 12, n n currn green beek Also, VDOT Road Design Manual, Appendix B1, pg. B(1)-8, Table 2. (Rev. 2) In process; see item #5, above. AASHTO excerpt deleted with Rev. 2. 7. Minimum of four (4) feet from edge of shoulder to ditch centerline. (5 Feb, rev.) Comment withdrawn. A ditch is not required given relatively flat terrain and absence of existing ditch features. If ditch requirement imposed, there is no existing network with which to connect at either end of roadway section under consideration. Runoff is from paved surface to shoulder, and from shoulder to undeveloped fields. 8. Grade < 16% calculated over a distance fifty (50) feet. (5 Feb, rev.) Comment withdrawn. GIS terrain contours indicate grade <16% calculated over a distance of fifty (50) feet, from end state maintenance to 150' beyond entrance to parcel 44-22D. 9. Rectangular zone super -adjacent to the street clear of all obstruction, including any structures and vegetation, that is at least fourteen (14) feet in width and fourteen (14) feet in height. (5 Feb, rev.) As follow-up: Requirement also applies at pillars. A pillar must be relocated. (Rev. 2) In process. Ref. item #5, above. 10. If the grade of any portion of the street exceeds seven (7) percent, the entire street shall be surfaced as required by VDOT standards. Streets having a grade of seven (7) percent or less may have a gravel surface. (1.-10., unless otherwise authorized by Chapter 14, Albemarle County Code) (5 Feb, rev.) Comment withdrawn. GIS terrain contours indicate no portion of the street exceeds seven (7) percent. In any event, existing surface is asphalt pavement. Engineering Review Comments Page 3 of 3 Road.

Note: Albemarle has option to request a separate road plan application, but will accept a PE sealed "s drawing of constructed improvements. in either- case (Road Plan/ As built), separate application with appropriate r-eview fee is required. in either case, approval of As built drawing or Read Plan design is required prior to final subdivision plat appFoval. If Applicant elects to submits a Road Plan that proposes improvements, as wouldarrow,. to be the ease (Ex. width ! 14 , then Road Plan improvements WAu need to be built, or improvements bonded, prior to final plat approval.
