[fax 434-296-5220] Owner or rep.: March Mountain Properties I (Block 1) Craig Enterprises, Inc. (Block 3B) Ja-Zan LLC(Block 3C) Plan received date: 9 July 2013 Date of comments: 13 August 2013 Reviewer: Michael Koslow Review coordinator: Michael Koslow The first road plan and comps submittal(SUB201300096) submitted 8 July 2013 has received Engineering Review and does not appear to meet Albemarle County minimum checklist items for approval. This review does not include a review of Erosion& Sediment Control, Mitigation, or Stormwater Management. Please adequately address the following comments for road plan approval: A. Application Information 1) Per ZMA2004-00024 proffer#7, please submit an overlot grading plan showing existing and proposed grading for this project. This could coincide with a road plan or site plan submittal but is needed for proposed subdivision. Overlot Grade lines shown for proposed grades. Spot Elevation also added. 2) Due to greater than 10,000 sft of disturbance proposed,this plan and associated final site plan(SDP2013-00044)will require an approved WPO plan including erosion & sediment control and stormwater management. The county acknowledges submittal of the erosion& sediment control plan(WP02013-00052). An existing facility which includes capacity to treat and detain runoff from the site could meet stormwater management requirements. A thorough check of existing enclosed drainage outfalls from the site is recommended. It is the county's understanding that this site no longer drains to the Old Ballard Field pond. Currently,the original Block 1 &3A Collins Engineering site plan accounts for the additional drainage associated with this future development area. The plan illustrated drainage outfalling into Upper Ballard Pond and accounted for the proposed Block 1B &3C site; the pond was also previously bonded with a WPO#and anticipated a storm sewer connection into the Upper Ballard Pond. A pond routing was included in that plan set illustrating the MS-19 conditions,and a copy can be provided if necessary. 3) After WPO plan approval but prior to grading permit issuance, a pro-rated share payment to Lickinghole Basin will be required. Understood,and thanks. NORIO *Wile Engineering Review Comments Page 2 of 3 4) Cover of final version of road plans will need to be signed, stamped,and dated by a professional engineer. Understood,and thanks. B. Existing Conditions Information 1) Please include the date the topographic information was verified by designer. All topography should be at least visually field verified by the designer with the last year. A note has been added to the reference on the cover sheet. C. Proposed Plan View Information 1) It appears that sidewalk maintenance easements could be necessary to maintain a minimum of 5' wide sidewalk continuity along proposed NE& SE corners of Old Trail Drive and Brookley Drive. Sidewalk maintenance easements have been added for the sidewalk proposed outside the right-of-way. 2) It appears that an easement for proposed sanitary sewer might be needed as it crosses Claremont Drive. Will defer to ACSA regarding this comment. Variable width utility easements have been added for all sewer and water mains. 3) Please include entrance detail for two entrances proposed on Brookley Drive. It appears CG-11 curb transitions are appropriate for the proposed mixed use parcels. CG-11 Locations were added to each commercial entrance. 4) Please indicate sight distance lines at Brookley Drive and Claremont Lane and for each proposed entrance on to Brookley Drive. Sight distance easements might be needed. Horizontal&Vertical sight distance lines were added to plan & profile. 5) Recommend showing a 20' wide easement for existing drainage pipe flowing under proposed Lot 23. This will be a requirement for the final plat as a condition of preliminary plat(SUB2012-00104)approval for block 1B. 20' Easement exists, but was not shown. Record information added,and easement plotted. 6) Please indicate stationing for Brookley Drive at a maximum interval of 50'. Stationing added to Brookley. 7) Please label all proposed intersection curb types, curb ramp types, and radii. All radii dimensioned,curb types and accessible ramps labeled. 8) Please propose traffic control signs(no parking signs on Brookley Drive if this is proposed condition consistent with proposed final site plans, stop signs, street name signs at intersections). Proposed and existing signage locations added to the plan. Engineering Review Comments Page 3 of 3 D. Plan Detail Information 1) Please specify 4"stone base for all proposed sidewalks including variable width sidewalks proposed on road typical sections on sheet 7. 4" Stone base added to the sidewalk shown on the typical sections. 2) Please update road name for Brookley Drive on Road Classification Schedule on sheet 5 (this name indicates Brookley Road). Brookley Drive is now reflected on all referencing labels. 3) Please propose a pavement design for Brookley Drive which supports proposed traffic loadings per 2009 VDOT Pavement Design Guide for Subdivision and Secondary Roads in Virginia or equivalent. Pavement design form included in submittal package. E. Street Profiles 1) Please include existing ground elevations at every 50' on profile. Existing ground elevations are now shown on the road profile. 2) Please indicate cross drains with VDOT designations(CD-1,2)at every cut and fill transition. Cross Drains added to profile at cut-fill locations along proposed portion of roadway. 3) Please label the intersecting stations for Old Trail Drive and Claremont Drive in profile view. Intersection station added to the profile. F. Street Details 1) Please clarify intent of"Typical Pavement and Curb Section Private"detail on sheet 5. It appears to be for the alley proposed to serve lots 14-20. However, the scaled distance from the front of the rolltop curb to the other curb line(as depicted in plan view on sheet 4) is only 22' while the detail indicates 24'. Also, please label proposed private R/W for this alley and/or indicate an access easement. Access easement added along private alley. Typical sections correspond to the commercial entrance sections. A section for the alley has been added,as well. G. Drainage Profiles 1) Please provide drainage profiles for all proposed drains associated with Brookley Drive and the alley which appears to be proposed to serve lots 14-20. Storm, Sanitary& waterline profiles revised or added to reflect all proposed locations. Current Development Engineering is available from 2:30-4 PM on Thursdays to discuss these review comments. Please contact Michael Koslow at 434-296-5832 ext. 3297 or email mkoslow @albemarle.org to schedule an appointment. COUNTY OF ALBEMARLE Department of Community Development 401 McIntire Road,Room 227 Charlottesville,Virginia 22902-4596 Phone(434)296-5832 Fax(434)972-4126 Project: Old Trail Village,Block 1B&3C Plan preparer: Roudabush,Gale&Assoc.,Inc [914 Monticello Road,Charlottesville, VA 22902,cmulligan@roudabush.com] Owner or rep.: JA-ZAN LLC [1150 Pepsi Place,Charlottesville VA 22901, dave@oldtrailvillage.com] Plan received date: 15 April 2014 Rev. 1 (WPO only) 29 May 2014 Road—see FILE: SUB201300096 Date of comments: 01 May 2014 Rev 1 (WPO) 11 June 2014/Approved Rev 3 (Road) 11 June 2014/Approved Reviewer: John Anderson A.Stormwater Management and Mitigation Plan (WPO201300052) 1. (Rev. 1) Comment addressed. 2. (Rev. 1) Comment addressed. 3. (Rev. 1) Response on file.—see Note,below Note—Storm sewer computations are not now found with SWM or ESC plans,but should be. They are relevant to SWM. Old Trail Village block 1B-3C E&S design relies on revised As-built drainage areas(DAs). Block 1B-3C final pipe grades deviate from design(not by Roudabush, Gale,&Assoc). This affects sediment basin design. There is a practical need to represent DAs that contribute to the basin,yet I struggled to piece this information together. As with computations,individual drainage areas appear on a sheet now removed from the ESC plan. The Engineering Review Comments Page 2 of 3 drainage areas shown on Road Plan sheet 4 overstate the DA. The best plan view of existing sediment basin DA is sheet 9 of a 13 sheet plan set titled Old Trail Village, Block 1,Phase B& Block 3, Phase C, Final Site and Over Lot Grading Plan. This sheet was brought to a project meeting May 15,but not included with the revised ESC plan. It appears that 4.44 Ac contribute to the existing basin. The basin, at 18,897 c.f.,is sized adequate for a 5.22 Ac. DA. At this point,I suspend request for additional detail relating to inlets,capacities,calculations, etc, and acknowledge VDOT's statement that block 1B-3C road plan appears to comply with VDOT standards and specifications,yet data in the storm sewer design table on sheet 7 of the Road Plan show point-to-point incremental and accumulated CAs that,using values included in this table alone,increase CA,point 106 to 108. That certain structures pre-exist does not mean they are unaffected by development. Runoff from point 20 to point 106 is new,but is carried by existing pipe. Old Trail Village is a large-scale development,and understanding can be tricky. I am not insensitive to developmental needs. My hope is that in the future, comments will be taken as simple request for information for purpose of comparison against limits and standards. The stormwater management and mitigation plan is approved as noted. The stormwater management approved with this plan is conveyance to the existing pond across Old Trail Drive.

C.Road plans (SUB201300096) Engineering Review Comments Page 3 of 3 Comment Addressed.—see Note,below Note-VDOT letter of April 14,2014 states no objection. Letter,however,makes mention of Final plat requirements:42'R.O.W. for Ashlar Ave(v. 39'),and sidewalk and street tree easement since VDOT will not maintain street trees or pavers along Ashlar Avenue. Also,VDOT states need for sidewalk and street trees maintenance agreement with Albemarle County;the County likewise does not accept maintenance responsibility for pavers or street trees. Given VDOT statement of no objection following their review of plans titled Old Trail Village Ashlar Avenue Road Construction Plan,dated 7/1/12 with revisions dated 9/27/13, 1/20/14,2/11/14,3/5/14,and 3/24/14 submitted by Roudabush, Gale and Associates,Inc.,and given design response to engineering review comments(13 August 2013 and 4 November 2013),Engineering approves road plan dated 24-Mar-14. D. Site Plan(SDP201300044) Comment addressed. E. Final Plat(SUB201400065) Review comments entered in County View(Alabemarle County project tracking system)on 5/28/14 1. Approved and bonded WPO required. WPO Application is under review(WPO201300052— requested changes). 2. Approved and bonded road plans required. Review of ACCD records appears to indicate road plans are not approved. 3. AC Code Ch. 14 § 303.I. requires"a definite bearing and distance tie between not less than two(2) permanent monuments on the exterior boundary of the property and further tie to existing street intersection where possible and reasonably convenient." Furnish bearing and distance ties. 4. Public R/W, Claremont Lane,is listed as 55',but elsewhere(road plans/WPO applications)as 61'. Please revise Claremont Lane public R/W as necessary. 5. The pro-rated share to Lickinghole Creek will need to be paid prior to plat approval. This will be handled with the posting of bonds. 6.A stormwater management maintenance agreement will be needed. This can occur with the WPO approval,but needs to happen prior to the final plat approval.
