Thank you for your comments dated November 27, 2019 on the above referenced project. Below are our responses to the
remaining comments on the road plans.
Engineering:
1. The plans have been signed and sealed, as requested.
2. The roll-top curbing detail has been added to the plans, as requested.
3. The transitioning of the roll top curbing to CG-6 at the inlets has been added to the plans along the alleys, as requested.
4. The cover sheet topography note has been updated for the current site visit and field topo verification.
5. North arrows have been added to the sheets that were missing them.
6. The horizontal curve information has been added to the plans on sheets 3,4,6,7,8 and 9.
7. All the pavement markings required for the project are now shown on the layout plan and road plan for Route 20
improvements.
8. The street trees have been moved away from the storm sewer as much as possible in the design, especially in front of lots
69 and 70.
9. The managed slopes have been shown and labeled on all the pertinent plan sheets, as requested.
10. The contour label has been updated, as requested.
11. The SWM easements have been added to the plans, shown and labeled.
12. The road crossings have been updated as requested, and the site now conforms to both VDOT and ADA requirements for
the crossings.
13. 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.
14. The drainage easements have been updated on the plans, and the drainage easements follow engineering's recent
determination on yard drains and roof drains and the sizes of the easements. All this has been updated, as requested.
15. Yes, an easement has been added to the pathways. A thickness and type of pathway has been added to the details on the
path.
16. (3) parking spaces that were affecting the sight lines have been removed from the street parking. We have extra parking
spaces, so this does not affect the overall project by just removing these 3 spaces.
17. The notes and details sheet has been updated, adding the note about the strength of the concrete.
18. The yard drains have been updated as requested, and none of them exceed the 15 ft/s velocity.
19. The proffers and conditions have been addressed with the road plans.
Planning (Daniel Butch)
1. The sidewalk along Avon Street has been updated to a 10' asphalt trail, as requested.
2. The sidewalk along Route 20 has been updated to an 8' concrete sidewalk.
Planning (Chris Perz):
1. 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 5' concrete sidewalk has been revised to an 8'sidewalk on both sides, as requested.
D. 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.
E. A note has been added to the plans to relocate the overhead power lines underground.
F. Street trees have been added and shown along Route 20 behind the sidewalk, as requested.
2. 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.
3. The note has been updated on the sidewalk to read as proposed, not existing.
4. No offsite easements are needed for the installation of the proposed improvements as currently designed.
5. A variation has been submitted for the removal of the cul-de-sac, which is no longer necessary.
6. The alley has been updated with a 30' private street easement, as requested to obtain the frontage.
7. All the planting strips have been called out and labeled.
8. 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.
VDOT:
1. It is noted on the cover sheet that the Access management Exception has been approved for the entrance onto Route 20
with the proximity to the commercial entrance.
2. The streets with the perpendicular parking spaces along them are all private streets. The labels have been updated.
3. The mid block pedestrian crossing has been removed.
4. The sidewalk crossing at lot 89 has been updated.
5. The barricades have been shown and labeled on the plans.
6. The right of way for Berwyn has been extended to the property line.
7. The sight line from Loyola along Berwyn has been updated to 280 as requested.
8. The curve data and PT, PC has been added to the layout sheet.
9. The sight line is correct. The sight line distance is measured along the centerline of the road to the point that is 280' from
the intersection, which was done. That is the sight line for the project at this intersection.
10. The route 20 improvements design has been updated for the 60 mph design.
11. The sidewalk is shown as 8' along route 20, due to the current proffer for this design.
12. A central mailbox has been shown and added to the plans in the central park area adjacent to Berwyn Street.'
13. The sanitary sewer is not located in any of the public roads. The other road are private, and the sewer can be installed
along the private roads. The labels have been updated.
14. The pavement note has been added to the plans.
15. The storm drainage structures have been updated and they are no longer deeper than necessary.
16. The inlets have been updated as required for the deeper manholes.
17. The HGL has been added to the plan sheets.
18. The grading has been updated and also shown on the cross sections. All the grading remains within the right of way.
19. This comment is acknowledged, and a note to this affect has been added to the plan sheets.
20. The sight distance has been updated for the 665 feet.
21. The trees have been positioned in accordance with the proximity to the intersections.
22. A note has been added about the HOA maintaining the landscaping.
23. A note has been added to the plans about the speed limit sign.
24. The entrance radii have been labeled for the Gropen commercial entrance.
25. This comment is acknowledged.
26. This comment is acknowledged.
GIS
1. The Warwick Court road name has been changed, as requested.
ACSA
1. Plans are approved, pending recordation of offsite utility easement.
