Abbotts Hall construction phase - issues and actions
Several potentially adverse impacts were identified as being likely to be associated
with the construction phase of this project. These include:
- Loss or damage to the sea wall flora and fauna where the breaches were proposed;
- Potential disturbance of reptiles, including loss of habitat;
- Impacts on borrow dykes, including species living in them;
- Disturbance of birds;
- Pollution;
- Damage to archaeological interest.
In order to mitigate these impact a mitigation measures and general good working
practices were adopted covering the following actions:
- Larger stands of special flora were avoided;
- Grassland close to the location of breaches was mown and minimised the impact
on reptiles;
- Disturbance to wintering birds was avoided by adopting practices (timing
of works in relation to tides etc.) advocated by English Nature;
- Breeding birds were discouraged from nesting close to construction sites
by mowing, rendering the vegetation unsuitable as nest sites;
- Application of the Environment Agency Pollution Prevention Guidelines minimised
the risk of pollution incidents;
- Archaeological interest were recorded and monitored by having an archaeologist
on site during excavation.

Guidance: The above summary of issues and actions is included
to provide an indication of the type of issues that might need to be addressed
when undertaking a managed
realignment. Note each site is probably unique in terms of
the issues that may arise, so it will be important to identify potential
problems at the outset and to adopt measures to mitigate the impacts.
The general conclusion from the Abbotts Hall scheme is that implementation
of such mitigation measures can significantly reduce the predicted impact
on the environment.
