Comments are provided below; however, additional comments or conditions may be added or eliminated based on further review.): [Each comment is preceded by the applicable reference, which is to the Subdivision/Zoning Ordinances unless otherwise specified.] 1. [ZMA201300012 Proffers] All proffers shall be adhered to as dictated in the proffers. Final: Comment still relevant. 2. [COD Sec 3.31 Lot Regulation/Setbacks. Replace the setbacks listed and depicted throughout the plan with the new setback chart (provided below) which was approved by the BOS on December 6, 2017. Please do not reword anything in the chart, merely provide the exact chart on the site plan. Additionally, revise the setbacks and buildable area depicted on all lots throughout the plan utilizing these new setbacks and the various factors provided in the chart. Final: Comment addressed. 3. [COD Sec 3.41 Building Height. Throughout the site plan label the maximum height of each structure by block that is being platted. See table 3.4 of the Code of Development as each block has different heights permitted based on the use. Example: Block G is permitted a maximum building height of 40 feet. Final: Comment addressed. 4. [COD Sec 7.11 Parking. The only portion of the development not subject to the 20% maximum rule for parking provided in excess of required parking, is that for Block D, as a waiver was granted during the rezoning for this block. All other blocks shall meet the 20% maximum for parking provided. Final: Comment addressed. Additionally, the minimum number of parking required in Blocks C, D, E, and F for NON-RESIDENTIAL uses in these blocks shall be based on the requirements for Shopping Centers, as contained in Section 4.12.6 of the County Code. Also, the calculations for NON-RESIDENTIAL parking shall be based on the total square footage within the block and not upon a per lot basis. Final: Comment still relevant but only for the nonresidential section, which is being pushed to a separate site plan. Also, provide parking calculation for the public park and identify the locations of these spaces. These spaces may be satisfied by either on -street spaces along perimeter of Block J, or provided using on -street or surface lots available to the public in adjacent blocks or in Block K's surface parking lot (see Sec 8 of the COD)). Final: The fire station parking lot in Block K is being proposed to serve the public park. As such this parking area shall be included on this final site plan. Permission shall be granted from the Fire Station and the offsite parking agreement shall be recorded in the Clerk's Office documenting the terms of this agreement. Based on existing conditions the parking lot will need to be upgraded to meet current parking lot standards. Also, provide the required parking study for a public recreation area (this should be developed in consultation with Dan Mahon of Parks and Recreation). The number of required spaces for the park shall be determined by the zoning administrator in consideration of the recommendations in the parking study, traffic generation figures either known to the industry or estimated by the Institute of Transportation Engineers, peak parking demands, and other relevant information. [ZMA201300012 Proffer 9] Affordable Housing. Designate which lots are the affordable units throughout the final site plan and final plat. Also, under the chart provide the full statement that reads: "The owner shall contribute cash to the County in the amount of Twenty -One Thousand, One Hundred Fifty Dollars ($21,150) instead of constructing each required affordable unit. Such payment shall be made after completion of the final inspection andprior to issuance of the certificate of occupancy for any such unit for which payment in lieu of constructing affordable housing is made. " Final: Comment not adequately addressed, applicant response to this condition is not adequate. On the plan identify the lots which will be the ADUs. 6. IZMA201300012 Proffer 2] Cash Proffer for Capital Improvement. The required cash contribution for each unit shall be dictated by the proffer and is required to be paid after completion of final inspection and prior to the issuance of a certificate of occupancy for each unit. Final: Applicant acknowledges the comment. 7. [ZMA201300012 Proffer 71 Rte 250 Landscape Buffer and Right of Way Dedication. Label, dimension, and depict the required 70' reservation zone and the 30' landscape buffer along Rte 250. These improvements shall be reserved for public use and dedicated upon the request of the County. The developer shall preserve the existing vegetation in this area as described in the proffer. Final: Comment not addressed. The Route 250 Landscape Buffer and Right-of-way dedication shall be appropriately labeled and dimensioned throughout the plan. Currently this area is labeled as "Amenity Space"; however, this is not an acceptable use of this land. Additionally, it is also labeled "SWM/BMP Forest/Open Space Easement"; however, this land shall not be used for this purpose either. The rezoning calls out the permitted uses in this area which can take place on the land until it is dedicated to the County upon demand for Rte 250 widening. Specifically, landscaped open space, signage, utilities. Remove the above uses from this land. On the plan provide a note for this area: "The 70' reservation zone and 30' landscape buffer are reserved for Public use and dedication upon the demand of the County. " "The maintenance and upkeep of these areas and their landscapinm shall be the responsibility of the HOA until the County demands dedication and accepts it: " 8. [COD Sec 3.2(4)] Density Regulations. A minimum of 20,000 SF of non-residential uses shall be in the development. On the plans label and depict where the required 20,000 SF non-residential use shall be located and assure there is enough area for 20,000 SF. Revise the Density by Block chart on sheet 4 to provide these calculations. Presumably these uses are to be in either Block D. Final: The `Density by Block' chart on sheet 4 contains incorrect density ranges for Blocks A, B, D, E, I, and J. Also, revise note #1 of the chart to mention the 20,000 SF nonresidential development in Block D. 9. [COD Sec 81 Open Space/Greenspace Preservation. Throughout the plan label the park as `Hereby Dedicated to the County of Albemarle for Public use as a Public Park". Final: Comment addressed. 10. [COD Sec 8] Open Space/Greenspace Preservation. Prior to final site plan approval the Director of Parks and Recreation is required to approve a park plan, which shall ensure amenities provided meet the needs of the County and satisfy the rezoning. Final: Comment still relevant. Dan Mahon provided the applicant comments on the park plan. Pending revisions of the final site plan to address these review comments. 11. [COD Sec 8] Open Space/Greenspace Preservation. The wetlands areas in the park shall be labeled as "Preserved Wetland Areas". Omit the reference to "Future Park" on sheet 4, as this area shall be part of the park with phase 2 of development. Final: Comment addressed. 12. [COD Sec 81 Open Space/Greenspace Preservation. Depict, label, and design a maintenance facility within the development for use by the County Parks and Recreation Department to maintain the public park facility. Also, coordinate with Parks and Recreation Department on the width and design of the trails throughout the park. Once coordinated provide `typicals' of these access ways. Prior to approval engineering and the Parks and Rec department shall sign off that these trails are adequate for use by motorized maintenance vehicles. Final: Comment is still relevant. These improvements shall be depicted on the site plan and approved by Parks and Recreation prior to final site plan approval. 13. [COD Sec 81 Open Space/Greenspace Preservation. The park has two required trail connects to the Eastpark Road. Currently these are depicted as easements; however, this is not appropriate and shall be revised to be fee simple dedications to the park. Depict, label, and dimension these trail connections. Additionally, the trail connections shall be increased in width above the 6' width as currently provided. These trail connections are to be utilized as access points for the public as well as used by Parks and Recreation Department to maintain the public park facility. Revise. Final: Comment addressed. 14. [Comment] On either sheet 4 or 5 provide a table of content overlay, which labels which sheets each section of various blocks can be found on. Final: Comment addressed. 15. [32.5.2(a), 32.5.2(i)] Existing or platted streets. Label all streets (public) and all alleys (private). Provide directional arrows on each alley to signify one way or two-way traffic. Also, provide the widths of all streets. Final: Comment addressed. 16. 132.5.2(a), 32.5.2(i)] Alleys. On the plan provide a note that states no public agency, including VDOT, and the County of Albemarle will be responsible for maintaining the alleys. Also, provide information on the plans that the alleys shall be dedicated and maintained by the HOA. Final: Comment addressed. 17. [ZMA201300012 Proffer 31 Route 250 and Eastern Entrance Improvements. "The owner shall either construct left and right turn lanes on Route 250 at the eastern entrance to the property or bond these improvements prior to approval of thefirst site plan or subdivision plat for the development... " Final: A road plan for the above referenced entrance improvements and all the roads in phase 2 shall be submitted and approved prior to final site plan approval. Staff is aware that the entrance improvements onto Rte 250 are currently bonded; however, no road plan was ever submitted or approved for these improvements. One is required. This 1st review of the final site plan does not cover a review of the improvements along Rte 250; rather, such heavy lifting will be done on the road plan and it's review. Once submitted and reviewed the road plan and the final site plan shall match for these improvements. 18. [Code of Development Section 4.21 Covenants to Provide Architectural Review Committee. Prior to final site plan and/or final subdivision plat approval a Declaration of Covenants, Conditions and Restrictions for Rivanna Village Phase II shall be reviewed/approved by the County Attorney's office in consultation with County Planning staff. The above document shall be approved by the County and recorded by the developer prior to final site plan and/or final subdivision plat approval. The DB page reference information of this recorded document shall be noted on the final site plan and/or final subdivision plat. Final: Comment not addressed. While this requirement was addressed for phase I, per conversations with the County Attorney it is not addressed for phase II. Please submit a Declaration of Covenants, Conditions and Restrictions for Rivanna Village Phase II. 19. [32.6.20)] Landscape plan. A landscape plan that complies with section 32.7.9 is required with the final site plan. Final: Comment Addressed. 20. [32.5.2(n)] Proposed Improvements. Provide the maximum footprint for all proposed townhome buildings. Final: Comment not addressed. 21. [32.5.2(n)] Proposed improvements. How is daily household trash going to be disposed of for these units? If each lot is going to have its own trash container for curbside pickup, where are these containers going to be stored when not in use? Final: Comment addressed. 22. [32.7.4.2] Easements for stormwater management facilities. Provide access to the stormwater management facility. Also, provide an easement over the facility and the access. Final: Comment addressed. 23. [32.8.2, 14-3111 Infrastructure improvementplans. Road plans must be approved and built or bonded prior to approval. On the initial site plan Fire and Rescue commented that the road widths are not adequate for on street parking. They have not provided staff comments on the plan yet. Work with Fire and Rescue to ensure the roads are wide enough to accommodate onstreet parking and that the spaces are dimensioned and labeled. Final: Comment still relevant. 24. [32.5.2(p) & 32.7.9.71 Screening. Proposed SWM Facilities shall be screened from the adjacent residential lots. Final: Comment addressed. 25. [32.7.2.1] Vehicular Access to Site. Each entrance onto any public street shall be designed and constructed as required by the standards of the Virginia Department of Transportation. VDOT approval of the entrance to the site shall be required prior to final site plan and/or final plat approval. Final: Comment still relevant. 26. [Comment] Provide the dimensions of proposed easements and whether they are to be publicly or privately maintained. Final: Comment addressed. 27. [32.6.2(e)] Public facilities and utilities. All water and sewer facilities to be dedicated to public use and the easements for those facilities and shall be identified by a statement that the facilities are to be dedicated to the Albemarle County Service Authority. Final: Comment addressed. 28. [Comment] On sheet 1 provide the site plan number and when submitted ensure it is labeled as Final Site Plan. Please omit Road Plan from the title. Final: On the plan provide the following SDP#: "SDP2018-31". Additional Comments on the Final 29. [14-409] Coordination & Extension. All public streets within a subdivision shall be extended and constructed to the abutting property lines to provide vehicular and pedestrian interconnections to future development on adjoining lands, terminating within the subdivision with a temporary turnaround. The three cul-de-sac streets that shall meet the above requirement are: Mossy Rock Road, Terrapin Trace, and Lazy Branch Lane. Please depict and label the right of way dedications to the property lines, reservation of the areas are appropriate at this time through the following note: `Area reserved for future right-of-way dedication upon demand of the County. " 30. [Comment] Label the land use of the hatched area adjacent to and fronting lots I-59, I-60, I-61, I-62, and J-48. What does the hatching signify? Hopefully it is a reservation zone for future right-of-way dedication, if so, labeled it `Area reserved for future right-of-way dedication upon demand of the County. " 31. [14-303] Cattail Court needs to be modified to a "30' private street easement". This private street is being relied upon for frontage of the townhomes. 32. [4.12] Parking. Label and dimension the two required parking spaces per lot for Lots F7, F8, F9, F10, F11, and F12. Additionally, on the site plan, with arrows, locate the guest parking spaces for these lots (staff assumes they are along Sedgwick Lane). 33. [4.12.5, 4.12] Location of Parking Areas. All parking spaces shall be established on the same lot with the primary use to which it is appurtenant, except as authorized by section 4.12.8. Lots G-11, G-25, G-26, G-27, G-41, G-42 are not provided 2 parking spaces on each lot. Nor are they provided guest parking spaces. Additionally, none of the full spaces are encompassed on the lot; rather, every space is a quarter outside of the lot. Block G is lacking the minimum number of required parking spaces. To correct this staff suggests you revise the parking area in Block G to no longer be on the individual lots, but instead locate them in congregate parking bays within a parking easements for the entire block. If you go this route the guest parking space requirement no longer applies. If you modify this, ensure the lots continue to meet the minimum lot size of 1,300 SF. Also, provide an instrument ensuring continuation of off -site parking shall be recorded prior to final site plan approval. If you do not modify parking as recommended, the required parking spaces and the required guest spaces will need to be provided for all lots in this block. 34. [4.12] Parking. Which townhome lots are the 21 lots you believe have a parking deficiency? Their location and access to on -street parking will determine if their parking is met through this alternative. If it is Block G you speak of, on -street parking will not suffice because it is separated by a public road. 35. [4.12.6] Parking Requirements. Dimension all parking spaces. 36. [32.5.2(n)] Trails. Throughout the plan label and dimension the trail and the trail easements (most are but some are not). Also, provide a cutsheet for trail design specifications. 37. [4.12] Parking. Provide column titles for the parking calculations chart. 38. [COD Sec 81 Open Space/Greenspace Preservation. Please work with Parks and Recreation to determine the appropriate method to separate and distinguish private residential lots from the public park (either fencing, berm, evergreen landscaping, or a combination). Prior to final site plan approval please depict and label the solution. 39. [Comment] The final site plan shall not be approved until all SRC reviewers have approved the plan. Their comments attached. 40. Additional Engineering Site Plan Review comments —thanks for drawing my attention to these items, Christopher: Additional Engineering review comments: 41. "55. Sheet C10 includes a proposed 200' taper and 200' right turn lane on U.S. Rt. 250 EBL. While Road Plan/s for this and other portions of public roads and privates streets (if any) internal to the development will present design information to be reviewed by County, VDOT, and others, at first glance, a 200' taper may be insufficient for a primary arterial roadway (55 MPH limit). Design for a similar development entrance located on U.S. primary arterial Rt. 29 with identical design /posted limits serves preliminary indication (prior to County review of traffic impact analysis) that proposed 200' taper to 200' right turn lane may require revision to ensure safe movement on Rt. 250, EBL, at current or future ADT projections. Please reference TIA, by date and title, that supports 200' taper and 200' turn lane for U.S. Rt. 250 EBL. As stated elsewhere, please submit road plans as required by ordinance." 42. "56. No portion of the 70' reservation zone or 30' landscape buffer that may in the future be dedicated to Albemarle County, upon demand, for widening of Rt. 250 may be placed in SWM /BMP Forest /Open Space Easement. Revise calculations or water quality compliance strategies that may at present rely on buffer areas that cannot with any assurance be preserved in perpetuity as forest /open space."

Brich, P.E. Commissioner June 11, 2018 County of Albemarle Department of Community Development 401 McIntire Road Charlottesville, VA 22902 Attn: Christopher Perez Re: Rivanna Village Phase II — Final Site Plan SDP-2018-00031 Review #1 Dear Mr. Perez: The Department of Transportation, Charlottesville Residency Transportation and Land Use Section, has reviewed the above referenced plan as submitted by Alan Franklin PE, LLC, dated 24 April 2018, and offers the following comments: I. Oversized structures, such as the proposed arch bridges, will only be approved if a maintenance agreement is recorded with the County of Albemarle. If VDOT is to maintain these structures, their sizes must be hydraulically justified. 2. Regardless of maintenance, arch bridges, box culverts, and retaining walls that are located within the ROW or- support structures within the ROW must be approved by the Culpeper District Structure & Bridge Section, as well as the Culpeper District Hydraulics Section prior to permit issuance. A maintenance agreement with the County/HOA for retaining walls located in or supporting structures within the ROW should be recorded prior to street acceptance. Comments from the Structure & Bridge and Hydraulics Sections will be forwarded as they are received. 3. Also concerning the arches, box culverts, and walls, a Geotechnical report is required including borings at each end wall. Borings must be performed in accordance with Chapter 3 of the VDOT Manual of Instructions (MOI). 4. Excessive right-of-way should not be granted for the purposes of having utilities. The right-of-way line should be I foot beyond the sidewalk. 5. Where DI-3s are greater than 8 feet deep, DI-3AA, -3BB, or -3CC should be specified as applicable and those details should be provided. The 9' requirement is for DI-2s. 6. The Drainage Manual states that pipe velocities that exceed 10 fps are to be avoided. 7. PIease show HGL's on profiles. Also provide HGL calculations, which should be consistent with existing plans showing existing structures that are being tied in to. 8. Typical Sections; pavement materials should be daylighted to the shoulder/slope, not abruptly terminated as shown. The pavement materials on the typical sections do not appear to have changed from the previous submission. 9. The Route 250 Improvements typical sections call for 2" of SM 9.5; as previously noted, the maximum lift thickness for SM 9.5 is 1.5". 10. Please provide the Route 250 Improvements on a single sheet, or two, fully dimensioned. VirginiaDOT.org WE KEEP VIRGINIA MOVING June 11, 2018 Christopher Perez Page 2 11. Why does the Lazy Branch Lane section decrease to 29 feet f/c to f/c? The roadway section should remain consistent throughout. This decrease in section width is not reflected in the typical sections. 12. PIease callout arches on layout plans, including dimensions. Note that design plans for only one of the three proposed arches has been provided. 13. It would be preferable to aid in and quicken the review process if the plans were scaled to a smaller scale. Note that the Department only requires that scales be 1":50'. 14. If the resubmission is printed and scaled to an architectural paper size, the Department will require hard copies to review. 15. Show the required area of mill and overlay on Route 250. 15. Provide pavement design calculations. 17. Please include the attached Construction Notes on the plans. Please provide two copies of the revised plan along with a comment response letter. If further information is desired, please contact Justin Deel at 434-422-9894. A VDOT Land Use Permit will be required prior to any work within the right-of-way. The owner/developer must contact the Charlottesville Residency Transportation and Land Use Section at (434) 422-9399 for information pertaining to this process. Sincerely, a6m, Adam J. Moore, P.E.

Add ornamental trees and large shrubs in the landscape buffer. 3. Distribute the trees and shrubs in the landscape buffer to fully populate the 30' depth and to achieve a natural appearance. 4. On the landscape plan, label the existing wooded area to remain and include notes identifying the character of the wooded area. 5. Revise the plan to remove all conflicts between grading and wooded area to remain. 6. Add the standard plant health note to the landscape plans: "All site plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature height; the topping of trees is prohibited. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant." Please provide: I . One set of revised drawings addressing each of these conditions. Include updated ARB revision dates on each drawing. 2. A memo including detailed responses indicating how each condition has been satisfied. If changes other than those requested have been made, identify those changes in the memo also. Highlighting the changes in the drawing with "clouding" or by other means will facilitate review and approval. 3. The attached "Revised Application Submittal" form.
