A SUMMARY OF
HS2 PHASE 1 ROUTE
1. The Colne Valley Regional Park lies on the
extremity of the northwest and west aspects of Greater London.
Its importance to the capital is due to it being "the first
real taste of countryside to the west of London."
2. The most dramatic aspects of the park are
its complex vast water attributes:
(a) River Colne;
(b) Grand Union Canal; and
(c) man-made lakes.
Natural England confirms that the river system is
"one of the finest in London".
3. The Colne Valley Regional Park encompasses
one of the capital's landscapes - Natural England's "London
4. The Colne River Valley Natural Signature is
20 kms long, but only less than 1 km wide at its widest point.
HS2 would cross the valley on a 3.6 km (2 ¼ mile) viaduct.
Given the width of the Natural Signature, a major transport scheme
such as HS2 has a potentially extreme negative impact on the public's
enjoyment of the regional park. Clearly, the viaduct would dwarf
5. HS2's proposed route particularly severely
impacts on the Colne valley because the route travels in a NW/SE
orientation as it crosses the valley. HS2's impact is not mitigated
by its being juxtaposed to any other built structure.
6. Because of the shape and size of the Colne
Valley Regional Park, the viaduct will have a considerable effect
on the public's enjoyment of the park:
(a) Walking/cycling/boating along the Grand Union
Canal are an important facility offered by the park.
(b) The River Colne, lakes and the canal are
rich in wetland wildlife and present a considerable public amenity.
The park contains several Sites of Scientific Special Interest.
(c) The lakes adjacent to the proposed HS2 route
are used extensively for sailing and angling.
7. Clearly, if a spur were to be constructed
to Heathrow that was orientated parallel to the River Colne in
the regional park, it would have further serious consequences
on the public's enjoyment of this amenity.
