Historical Context

Knepp Mill Pond is a man-made feature, created by the formation of a clay dam, or bay, across a shallow stream valley. It was created in connection with the iron industry as a means of developing a head of water to drive a waterwheel, either powering a set of bellows to fire a furnace, or a hammer to crush iron ore. Other mills may later have taken advantage of this power supply to drive corn-milling machinery.

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.
