Final detailed
design of the project
This design has been
approved by the Estate and used as the basis
for the restoration plans. There were no
adverse comments with regard to either the
design or the restoration plan at the public
exhibition on 6 November 2009.
The
design of the southern bund has been amended
to a thin L shape and only will be built if
the A24 road improvements do not go ahead.
It will be necessary to phase the
operations such that the southern bund is
constructed at a late stage in the
development. Survey data is available
for the footprint of the southern bund that
is in place currently but not for the height
or cross section of the bund. It is
estimated that the bund is approximately 1m
high with slopes of approximately 1v:2h to
1v:2.5h. There are tall leylandii on
the top of the current bund which will be
removed. The design of the southern
bund incorporates an outer gradient of
1v:2.5h to a height of 3m with a 3m wide
crest. The inner slope down to the
paddocks is designed at a gradient of 1v:3h.
The central landscape
bund has been designed to the west of the
proposed access route to Hill House Farm.
The central bund has been designed so that
there are gentle gradients on the castle
side of the bund and a steeper gradient to
the proposed access route to Hill House Farm
on the A24 side of the bund. The
gradients are between approximately 1v:5h to
1v:20h on the castle side of the bund and
approximately 1v:3.5h on the A24 side of the
bund. Generally the bund rises to
approximately 4m higher than the current
ground levels and the crest of the bund
falls from north to south consistent with
the existing ground level. There are
pinch points at the northern and southern
end of the bund where due to trees or the
road alignment there is only enough space to
accommodate a 2m high bund. The
minimum width of the bund is 20m and the
maximum width is 120m. The bund has a
3m wide flat crest. It is now not necessary to move
Bow Barn as part of the construction of the
landscape bund.
