RE: Bundoran Farm (Winsome Orchard Lane)
As -Built Road Plan
Mr. Pohl,
Upon receipt of the as -built survey by Roudabush, Gale & Associates, Inc. for Winsome
Orchard Lane, the plans were inspected for discrepancies between what was proposed
with the Road Plan Amendment 1 to SUB-2006-00417, dated 05/05/2021, and what was
built. A field inspection was performed on 05/06/2022 to verify the information provided
by the as -built survey. The as -built generally conform with the intent of the proposed
plans with some deviations which are elaborated upon below.
Entrance
The geometry of the entrance deviates from the proposed design, but still meets VDOT
standards for a commercial entrance design to serve a private subdivision road/street.
The entrance profile does not meet VDOT minimum K values, but does satisfy other
VDOT criteria.
• The entrance is paved to a width of 25.04 ft at 25 ft distance from the main road's
edge of pavement (EOP).
• The eastern radius is roughly 20 ft as it connects with the road, but the overall
pavement is wider in this location than proposed, resulting in an effective radius
in excess of 25 ft.
• The entrance grade descends from Edge Valley Road EOP for 13 ft before
ascending, which satisfies VDOT's concerns for keeping drainage out of the public
road and for safety of those plowing the roads. Please see Figure 1 below. As
shown on the entrance profile in the As -Built Plans, the vertical curvature of the
entrance does not meet the minimum K value.

Road Typical Section
The as -built conditions reflect the intent of the typical sections for the 16 ft and 13 ft
roadway sections.
• The 16 ft roadway section was paved with 1.5" SM9.5A, though the proposed
surface was primed and triple sealed (1.5" asphalt was visually confirmed, but no
borings were taken).
• The 16 ft roadway section is roughly 17 ft from EOP to EOP.
• Total road and shoulder width of 20 ft is provided except for one discrete location
near station 4+50, where it is only 19 ft.
• The 13 ft section of road is adequate in total road and shoulder width, but the
width of asphalt is less than 13 ft in most areas (12.5 ft minimum). A design waiver
has been obtained to allow the as -built width.
Drainage Items
The proposed entrance culvert and all rip rap were built in accordance with the
proposed plans. Areas that were previously experiencing erosion are now stabilized.
Please see Figures 2 and 3 located as attachments. All drainage items are located
within drainage easements or the 40 ft ROW. Easements and new ROW width were
recorded with Instrument No. 202100011779, and a copy is included on the last page
of the As -Built Plans.
Winsome Orchard Lane was built in general conformance with the approved plan. The
minor deviations on the site still conform to regulations and to the intent of the plans.
Areas that were of concern for erosion have been stabilized and all comments (dated
9/30/2020) from the initial bond release request have been addressed.
Respectfully submitted,
