The "lower" proposed Open Space (identified as an approximately 3.91-acre area labeled as "Greenway Reservation" on corresponding Draft Special Lot Plat) should also continue to be designated as Open Space on the Final Site Plan, and must remain designated as being reserved for future dedication to the County (as has been previously established by, and as is required by, the terms of recorded plat in Deed Book 2913, pages 156-162, recorded 2/1/2005) c. (*) Note: CDD-Planning staff will continue to coordinate closely with the applicants and consultants, as well as all other regulatory stakeholders, to successfully identify a solution to the issues associated with the proposed Open Space (shown on the Final Site Plan) in relation to the proposed SWM Forest/ Open Space Easement (shown on the WPO Plan). Rev. Comm. #3: Comment#31 is no longer valid, and is withdrawn. As conveyed in writing (email correspondence to Trey Steigman dated 5/20/2019, attached), the proposed Open Space should not be subject to a public use and access easement— it should continue to be designated as being reserved for future dedication to the County for public use, as was the applicant's intention prior to the issuance of this comment #31 on 5/10/2019 32. [Z.O. Sec. 32.7.9.4.(d)] Please add the required "verification of compliance" note to the Landscape Plan.

[Z.O. 32.7.91: Please revise Landscaping Plan(Sheets 9 and 10)as follows(below); and please note that CDD-Planning staff remain available to discuss these issues and address any questions you may have: a [Z.O. Sec. 32.6.2(j),32.7.9.51: Resolve apparent conflict between proposed location of the street trees (two Ulmus parvifolia)and the proposed retaining walls. It appears that one tree is shown as being proposed on the wall. Staff acknowledges the constraints in this vicinity with the extent of the right-of-way, existing grade and proposed grading, location of proposed retaining wall,and location of proposed storm drain pipes and associated easements. RESPONSE: Location of offending tree has revised. b [Z.O.Sec.32.7.9.7.a.2,32.7.9.1.f,and 32.7.9.1.h]: Add additional landscape screening materials to the area south of the proposed parking area(where 14 screening trees Osmanthus x fortuni are currently proposed), in order to better ensure that the proposed parking will be sufficiently screened from the adjoining residential district. In making this revision, staff recommends specifying more than one species of landscape screening materials; and staff also encourages the use of native evergreen materials (such as Pinus, Ilex, Viburnum, Rhododendron, or Kalmia species)and/or native trees which retain their leaves for significant portions of the fall and winter(such as certain Quercus species or Fagus grandifolia). RESPONSE: I switched out the Osmanthus with three native species that will provide better screening than the handful of the other shrubs. They are more in a staggered row pattern. I used the Juiperus, Rhododendron and Viburnum all evergreen. The different varieties each have a different texture so they will be very aesthetic pleasing. 35. [Advisory]: It is the understanding of CDD-Planning staff that any maintenance within VDOT ROW is conducted solely by VDOT; please coordinate with VDOT staff and Albemarle County Parks and Recreation staff to determine the necessity of revising the following notes on Sheet 3 (Site Layout Plan): a "Proposed pedestrian crosswalk to be maintained by developer" and b.

[New] (Rev.3) Sheet 17: Reduce outlet velocity to under 15fps by dropping MH 1 lower. Response: Please see sheet 16. The pipe from MH1 to the outfall has been reduced to 4.26%which resulted in the exit velocity to be under 15 fps. Please see the top chart in the bottom left corner. Additionally, I have called for an energy dissipater to be constructed at the pipe outfall to further reduce the velocity before the water enters the channel. Provide anchors for the 36" culvert (over 16% slope). Response: Anchor detail has been on sheet 23. Additionally, label has been added to the profile on sheet 17. Provide detail of energy dissipator at end of culvert. Response: Detail added to sheet 23. Please show correct width and depth of channel. Plan/Cross-section shows it as 6'w & 1' deep, and the Profile/Report show it as 8'w & 1.5' deep. Response: The channel report and profile view have been corrected. The channel is 1' deep, 6' wide at the top. Provide stone sizing calcs for the channel linings (Refer to E&SC HB, Chapter 5: Flexible liner method). Response: As the labels indicate on sheet 17, the channel conveying water down the critical slopes is a grouted riprap channel. Therefore, tractive force calculations are not germane. Additionally, fabric liner under a concrete channel is not warranted. This comment was withdrawn by David James at a meeting at the County office on 12/19/2019. How did you determine the n-value of 0.04 from Channel Report? Response: The n-value of the 0.04 for the channel report is from the publication of "Water resource Measurements: A Handbook for Hydrologists and Engineers" by Bruce Van Haveren. On page 106 Table 11.15, "excavated channel with jagged and irregular rock cuts n = 0.04". Showllnstall fabric liner underneath the riprap of channel. Response: As the labels indicate on sheet 17, the channel conveying water down the critical slopes is a grouted riprap channel. That is a concrete channel with riprap embedded for energy dissipation as the water travels down the hill. Therefore, tractive force calculations are not germane. Additionally, fabric liner under a concrete channel is not warranted. This comment was withdrawn by David James at a meeting at the County office on 12/19/2019. [New] (Rev.3) Please show correct width of drainage easement. The easement width shown is 25' wide and should be about 28' wide for pipe Str. 2-1. 2'(dia.) +2'+2(12-5') +10 = 28'. & Likewise, for 1- out. Response: On the previous submission, the drainage easement shown is 30' wide starting at outlet of structure 2 to the outfall. [New] (Rev.3) Retaining walls: At least the height of the wall should be maintained from the property line. [DSM, p. 22] Ensure an off-site easement will not be required to construct the wall; otherwise, provide letter of permission. Response: We have provided the listed items required by the DSM on page 22, section B.2. with the retaining wall design packet submitted under separate cover. This comment was withdrawn by David James at a meeting at the County office on 12/19/2019. Sheet 3/9— Move tree from on top of wall #1. RESPONSE: Location of offending tree has revised.

After recent coordination with County staff within and outside of the Community Development Department, the "upper" proposed Open Space (identified as an approximately 2.99-acre area labeled as "County Park" on corresponding Draft Special Lot Plat) should no longer be reserved for future dedication to the County due to the overlapping (proposed) SWM Forest/Open Space Easement in this same area. Instead, this "upper" proposed Open Space should continue to be designated as Open Space on the Final Site Plan, but with a new designation as a proposed public use and access easement, and this public easement will need to be shown on the corresponding Special Lot Plat and also the corresponding Easement Rat submission (with corresponding legal documents also being required). b. The "lower" proposed Open Space (identified as an approximately 3.91-acre area labeled as "Greenway Reservation" on corresponding Draft Special Lot Plat) should also continue to be designated as Open Space on the Final Site Plan, and must remain designated as being reserved for future dedication to the County (as has been previously established by, and as is required by, the terms of recorded plat in Deed Book 2913, pages 156-162, recorded 2/1/2005). c. (*) Note: CDD-Planning staff will continue to coordinate closely with the applicants and consultants, as well as all other regulatory stakeholders, to successfully identify a solution to the issues associated with the proposed Open Space (shown on the Final Site Plan) in relation to the proposed SWM Forest/ Open Space Easement (shown on the WPO Plan). RESPONSE: In phone conversation and follow-up email from Tim Padalino, dated 20 May 2019: "The Open Space areas shown on the final site plan and special lot plat can and should remain designated as being `reserved for future dedication to the County for public use.' The Open Space areas should not be designated as a public use and/or public access easement. These updates override / supersede review comment #31 from the 5/10 review comment letter. In coordination with multiple County Divisions and Departments, it has recently been confirmed that the reservation for future dedication is acceptable. I apologize for any uncertainty and delay that may have resulted from the varying guidance provided by County staff." 32 [Z.O. Sec. 32.7.9.4.(d)] Please add the required "verification of compliance" note to the Landscape Plan. Please include the following standard plant health note: "All site plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature height; the toping of trees is prohibited. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant." RESPONSE: The note has been on sheet 9 "Landscaping Plan notes & details" under "General Notes & Minimum Standards". Verification of compliance has been added. Additionally, the notes have been added to plan view on sheet 8 to provide additional clarity. 33. [Advisory]: It is the understanding of CDD-Planning staff that any maintenance within VDOT ROW is conducted solely by VDOT; please coordinate with VDOT staff and Albemarle County Parks and Recreation staff to determine the necessity of revising the following notes on Sheet 3 (Site Layout Plan): a. "Proposed pedestrian crosswalk to be maintained by developer" and b. "Location of proposed pedestrian crosswalk and connection point to trail to be determined and maintained by Parks and Rec Dept." c. Note: Permissibility and location of proposed crosswalks are subject to VDOT approval; CDD- Planning staff strongly support the design and implementation of pedestrian crosswalks (with appropriate signage, as may be applicable) across South Pantops Drive, which would also support and advance relevant Comprehensive Plan goals and recommendations. RESPONSE: The northern most crosswalk has been removed per VDOT request. The crosswalk at the entrance has been resolved with VDOT. (see VDOT comments below) 34. [Advisory]: The following remaining approvals are required prior to approval of final site plan SDP-2018- 00085: a. [Z.O. Section 32.7.4.1.a]: Water Protection Ordinance Plan (and corresponding legal documents) /WPO-2018-00095 b. [Z.O. Sections 32.7.4.2 and 32.7.5.3]: Easement Plat (and corresponding legal documents) c. [Z.O. Section 32.7.1.1]: Special Lot Plat (and corresponding legal document) / SUB-2018- 00176; and d.

Virginia Department of Transportation (Adam Moore) 1. The 12' offset and taper, turning right out of the entrance, is a requirement for entrances along highways with shoulders. However, this plan proposes curb and gutter. Please see Figure 4-10 on page F-109 of Appendix F. Response: The entrance has been corrected. 2. Sidewalks must be 8' in width if adjacent to curb without a buffer strip. Response: Per appendix A(1)-71: "No" on-street parking situations 5 foot sidewalk with no buffer strip requires the submission of a design waiver. Waiver request is included with this submission. 3. Please provide more detail concerning the proposed flume; what warrants this and how does this alleviate the concern? It appears that a DI is warranted here instead, which must lead to an established outfall. Response: The existing conditions of the site has no curb and gutter and the water is allowed to flow freely over the slopes to the creek below. Albemarle county planning department has requested that sidewalk be installed along the frontage of this parcel to allow for pedestrian interconnectivity in Pantops. Along with the submission of the Final Site Plan, I have included an exhibit which shows a profile of a potential manhole and pipe that would outfall to the existing drainage channel. The drainage area contributing to the flume is 0.26 acres. A flume is proposed in lieu of an inlet and pipe due to the proximity of the existing waterline, 18" Asbestos sanitary pipe, and critical steep slopes (please see the profile provided). It is the desire of the County Engineering Department to avoid disturbance to the Steep Slopes. The installation of a curb cut and paved flume is the least invasive option. I have also included photos of similar design flumes in the area. 4. The proposed crosswalk markings on S. Pantops Drive do not appear to be warranted. Please see IIM-TE-384. Additionally, please provide justification for any proposed midblock pedestrian crossings of S. Pantops Drive. Response: Resolved via phone call with Justin Deel on 5/28/2019. The crosswalk at the north end of the parcel has been removed. Crosswalk at entrance to remain. 5. CG-12s are needed at the site entrance, angled perpendicular to the entrance. Response: CG-12 have been added at the entrance. 6. The entire adjacent through lane throughout the width of the entrance must be included in the area of mill & overlay on S. Pantops Road. Include callout on plans indicated this is the area to be milled & overlayed in accordance with the WP-2 detail. Response: The label has been corrected.

March 29, 2019 Ms. Mariah Gleason Department of Community Development 401 McIntire Road Charlottesville, VA 22902 RE: SDP-2018-00085 Vistas at South Pantops— Final Site Plan Dear Mariah, Please find attached the revised plans. The plans have been revised to address the comments in accordance with the following: 1. [Z.O. Sec. 32.6.2(a), 32.5.2(a)] On Sheet 1, please amend the project number for this final site plan to "SDP2018-00085." Please also include the initial site plan project number (SDP2018-00008) on this sheet for reference purposes. RESPONSE: The number has been amended and Initial site plan number has been added. 2. [Z.O. Sec. 32.6.1(b)] Please submit one (1) reduced copy of the final site plan no larger than 11x17 inches in size. RESPONSE: A reduced copy of the plan will be added to this submission. 3. [Z.O. Sec. 32.6.2(a), 32.5.2(a)] Review of the deed book records and County GIS indicate this parcel (78-20) is 13.12 acres in size, as compared to the 13.31 acres listed in the site plan. Please review and revise these values to conform with parcel records. RESPONSE: Boundary information is based on a boundary survey performed by Dominion Engineering, dated 09/07/2017. It is my interpretation that there is a slight discrepancy due to the rear property line following the centerline of the river, and therefore, some interpretation and natural fluctuation of the river occurs. Note 9 on the boundary plat addresses this problem. The area of 13.308 acres (13.31 acres rounded) is the same area used on the approved subdivision plat by Roudabush, Gale and Associates where we created the special lot. 4. [Z.O. Sec. 32.6.2(a), 32.5.2(r)] The plans do not appear to adhere to, or include, many items included in the legend on Sheet 1. Please revise the legend and/or plans to be consistent with one another. RESPONSE: The legend on sheet 1 has been updated to reflect the line types being used in plan view. 5. [Z.O. Sec. 32.6.2(a), 32.5.2(r)] Throughout the plan, please ensure that all identifying lines are labeled, by connected leader line or legend, and that they are easily distinguished from one another. Please pay particular attention to Sheets 2 and 7. RESPONSE: Line types have been changed and additional text with leaders have been added for clarity. 6. [Z.O. Sec. 32.6.1(e)(6), 32.6.2(a), 32.5.1(c)(4)] Please provide horizontal dimensions for all proposed structures. RESPONSE: Additional dimensions have been added. 7. [Z.O. Sec. 32.6.2(a), 32.5.2(s)] With regard to utilities noted on Sheet 6, please include notes if any lines will be demolished, disturbed, or relocated during construction. RESPONSE: The existing sanitary sewer will be demolished and removed in accordance with ACSA standards. 8. [Z.O. Sec. 32.6.2(g)] Please ensure that all existing and proposed public easements are identified in the plans. RESPONSE: All existing and proposed easement layers have been turned on.

Additional labels have been added to indicated the proposed improvements. 2. Please explain the proposed hatching located right of the entrance on Route 1140. The proposed turn lane should tie in to the existing turn lane, making a continuous right-turn lane. RESPONSE: The first submission of the FSP showed a right lane being added along the entire frontage of the property. For this submission, only a right taper lane is proposed (and required). The existing guardrail is to remain except where there is conflict with the proposed addition of the taper lane at approximately the last 36 feet near the entrance. New guardrail is proposed for this section and is offset 1 foot from the proposed 5-foot sidewalk. CG-6 and a 5-foot sidewalk is proposed along the frontage of the property. The CG-6 at the north end of the property will connect with existing CG-6. New guardrail will be installed at this portion as well. 3. A 3-foot buffer strip is required between the curb and sidewalk. RESPONSE: Adding a 3-foot buffer strip would require the applicant to demolish the entire length of existing guardrail and would require construction of a retaining wall in the critical slopes for grade lines to tie in. Since the east side of South Pantops Drive does not have a 3-foot buffer strip —the applicant would like VDOT to consider the effect of the buffer strip due to space constraints. 4. All retaining walls that support structures within the right-of-way must be approved by the Culpeper District Structure & Bridge Section.

The retaining wall along South Pantops Drive has been removed from the plan since only a right-taper is required. The handrail for the wall on the south side of the entrance will meet all required safety standards. 6. The bench behind the guardrail must be at least 4 inches, and, if less than 2 feet, guardrail posts must be 9 feet in length. RESPONSE: The retaining wall along South Pantops Drive has been removed from the plan since only a right-taper is required. 7. Provide all applicable VDOT Guardrail Standards (MASH). Show guardrail end sections on plans. RESPONSE: Detail and labels have been added to the plan. 8. There appears to be guardrail between the sidewalk and street on some plan sheets; is this just the existing guardrail layer left on? RESPONSE: The existing guardrail is to remain. 9. Do the proposed earthwork, retaining wall, and guardrail installation affect the existing 54" culvert? Previous plans showed a connection being made to this culvert; is this no longer the case? RESPONSE: Proposed CG-6 and sidewalk improvements does not affect the existing culvert. A flume and channel is proposed at the low point of South Pantops Drive that will connect to the existing rip rap channel. 10. What is the hatched area along the proposed sidewalk/guardrail? RESPONSE: Hatching and dedication is no longer proposed — only a right taper is required. 11. The proposed crosswalk markings do not appear to be warranted. Please see IIM-TE-384.
