Table 10.7 Potential Construction Impacts on Non-Statutory Designated Sites, Notable Habitats and Notable Species
Features Potential Impacts
Non-Statutory Designated Sites
Non-statutory designated sites
for nature conservation
Undesignated Habitats
Lowland Calcareous grassland
UK BAP habitat
Arable field and margins
Middle Drain and ditches
surrounding the application site
Non-statutory designated sites include North Moss Lane Meadow SNCI, Stallingborough
Fish Ponds LWS and Laporte Road Brownfield Site LWS.
There would be no habitat loss within these sites. No indirect impacts are predicted on
these sites due to their distance from the development area and lack of connecting
habitats (i.e. there are no identified pathways from the site to these sites through which
impacts could occur).
There would be no loss of this habitat. No effect on this habitat is expected due to the
distance of over 800 m from the development area; the existing BOC site also lies in
between the development site and the grassland. There are no connecting habitats or
identified pathways through which impacts could occur.
The land take will include permanent irreversible loss of arable land (~2 to 4 ha). Arable
land has very little intrinsic value for nature conservation and this habitat type is common
in the UK and in the local area. The loss of this habitat within the redline boundary would
not lead to any significant ecological effects (see also birds below).
For the most part arable field margins would be retained due to the 7 m maintenance
strip along Middle Drain and the 18 m Anglian Water easement along South Marsh Road.
A very small area of field margin along the boundary with the Railway Line to the west of
the application site could be lost temporarily during construction but ultimately this area
will be managed for the benefit of wildlife in the long term. The temporary loss would not
result in negative impacts on the conservation status of the habitat (see also reptiles
below).
A bridge (two lanes wide) is to be constructed over Middle Drain. The bridge will have a
carriageway of 8.2 m, plus 1.5 m for a footpath to one side only, plus 1 m each side for
the structure, so overall width would be approximately 11.7 m.
There will be a 7 m maintenance strip along the top of the bank of Middle Drain and no
construction activities will occur within this zone, other than in the immediate vicinity of
the bridge footings landings. The bridge footings landing area will be at least 5 m from the
top of the banks and construction activities will not occur within 5 m of the top of the
