Thank you for your comments dated December 17, 2019 on the above referenced project. Below are our responses to the
remaining comments on the road plans.
Planning:
1. A new variation has been submitted for review, reverting back to the original application plan for the development. The site
plan is in conformance with the updates, per the variation request. It is understood that the final site plan will not be approved
until the variation has been approved by the BOS.
2. The variation that has been submitted also addresses the removal of the cul-de-sac. The private roadway right of way has been
extended to the southern property line, as requested by VDOT, to provide a connection for future development.
3. Cu.,_—, N, __y Qu , .....u.
4. Comment previously addressed.
5. The variation that is currently under review also addresses the setbacks within the development. New setbacks have been
established with the variation that will be easier to enforce during the building permit process, and the setbacks are more in
line with the current Albemarle County setbacks for the other zoning districts in the county.
6. The yard drains have been relocated outside of the 20' landscaping easement along the southern property line to provide a full
20' buffer where the rear lots are adjacent to the property line.
7. The acreage of the blocks have been added to sheet 3 and sheets 4 and 5. In addition, the cover sheet has been updated to
show the block areas as well. The variation updates to the block acreages back to the original block acreages from the rezoning,
prior to variation #1, and the block acreages as shown in the final site plan are within the permissible 15% variation of the block
size allowed by the Code of Development with respect to the original block acreages.
8. The central park has been updated to an area of 1.0 acres. The variation addresses the size of the central park and the other
pocket parks and open space throughout the development.

13. A subdivision plat is currently under review for the project. The plat will be recorded and the Deed book and page numbers
shall be added to the easements once the plat is recorded. It is acknowledged that the final site plan will not be approved until
the subdivision plat is approved.
14. This comment is acknowledged. The water and sewer plans are approved, and the contractor is currently installing the
infrastructure. These improvements will be bonded with the subdivision plat.
15. The existing conditions sheet has been updated to show the county's steep slope overlay, as requested.
16. C _,viously addresse
17. The proffers have been revised, as requested.
18. As noted in comment #14, this comment is acknowledged. The water and sewer plans are approved, and the contractor is
currently installing the infrastructure. These improvements will be bonded with the subdivision plat.
19. The landscaping plan sheets will be submitted separately for the project for review. They are being completed now with the
proposed amenities for the project.
20. This note has been added to Sheet 5 — site plan. See note #14 on this sheet.
21. This comment is acknowledged. The WPO plan is approved, but an amendment shall be processed for some final changes to
the plan. The road plans are currently under review for approval as well.
22. The right of way dedication area along Route 20 and Route 742 are shown on sheet 3, and sheets 4 and 5. These areas are
labeled on these sheets as well.
24. This comment is acknowledged.
26. The comments have been addressed as followed:
A. The sidewalk has been extended as far as possible to TMP 90-27, while still allowing the grading to tie-in between the
improvements and the existing topography on their property within the VDOT easement. We have built the
improvements as far as we could for the tie-in connections and when this property is developed, they will be able to tie-in
to our improvements within the right of way and make the connection.
B. The proposed grading has been modified because the original grading and road plans were not VDOT approvable. The
existing design for the Rt. 20 improvements was lacking the details and necessary design for VDOT approval, as outlined in
the final site plan comment letter to Alan Franklin back around 2013. That design was not approvable. We have worked
with VDOT to design an approvable Route 20 improvement plan for the access into the site, and the grading is a result of
these improvements that are approvable by VDOT. While the grading may not be exactly the same, the concept and intent
of the Route 20 improvements is the exact same.
C. The 8' sanitary sewer has been extended to the property line of TMP90-27 along the private road (Berwyn) for the utility
connection to the adjacent property.
D. A note has been added to the plans to relocate the overhead power lines underground.
E. Street trees have been added and shown along Route 20 behind the sidewalk, as requested.
F. A 6' planting strip has been provided along Route 20.
27. The comments have been addressed as followed:
A. The sidewalk has been extended as far as possible to TMP 90-27 and TMP90-35A1, while still allowing the grading to tie-in
between the improvements and the existing topography on their property within the VDOT easement. We have built the
improvements as far as we could for the tie-in connections and when this property is developed, they will be able to tie-in
to our improvements within the right of way and make the connection
B. The 5' sidewalk has been revised to an 8' asphalt path, as requested.
C. Street trees have been designed along the pathway.
D. A 6' planting strip has been provided along Route 742.
28. An overlot grading plan was part of the VSMP plan and is part of this site plan. The grading and overlot grading is shown on
sheets 8 and 9, and required.
29. All the planting strips are now shown and labeled.
30. The grading has been updated to remove any grading on to TMP 90-27B.
31. The overall park area has been increased from the required 2.68 acres to 2.93 acres throughout the project. With the increase
in area, a small portion of the Park #1 is being utilized as a dry retention area. This area will also be landscaped as part of the
overall park amenity areas. In addition, the area of the pocket park #1 has increased from 0.64 acres to 0.68 acres to
accommodate the 0.04 acres that is within dry detention basin. This is also included in the variation request.
32. The comment is acknowledged. The final subdivision plat will be recorded prior to the approval of the final site plan.

contractor is currently installing the infrastructure. These improvements will be bonded with the subdivision plat.
34. As noted in comment response #7, the acreage of the blocks have been added to sheet 3 and sheets 4 and 5. In addition, the
cover sheet has been updated to show the block areas as well. The variation updates to the block acreages back to the original
block acreages from the rezoning, prior to variation #1, and updates the overall phasing for the blocks within the development.
35. The width of the landscaping easements along the northern and southern property lines have been increased to 20' wide,
except for the location of the alley and private street. The alley and private street are shown in the location as noted on the
original approved site plan.
36. The landscaping plan is being updated to include the proposed site amenities for the project. A substitution request shall also
be submitted for review with this project to reduce the number of tot lots and substitute them for additional amenities.
37. A 6' landscaping and maintenance easement has been provided along the right of way in front of the residential lots to ensure
adequate room for the proposed street trees. The easement will be platted with the subdivision plat.
38. The declarations of covenants, conditions, and restrictions is being submitted with the final subdivision plat and will be
recorded with the subdivision plat, prior to the final site plan approval.
39. The planting strips along Route20 and Route 742 have been updated to 6' planting strips and labeled as 6' planting strips.

this was an approved design with an application plan that was part of the rezoning, the applicant requests that the
approved application plan serve as the approval that perpendicular parking spaces will be allowed for this development.
6. The wall designs are being finalized now, and will be submitted to the county with a building permit plan for review. A
copy of the wall designs will be provided to engineering as well.
7. The grading has been updated for the development and all the grading along the northern and southern property lines
