Significant mitigation required for severe constraints. Recommend a review of the site and potential removal from the local plan.

From the description provided, we have concluded these are the same site and have reviewed accordingly. If this is not the case, please disregard the comments provided by the LLFA and reconsult with updated data.

The on-site flood risk is a major flow path in the 0.1% AEP event. It affects the majority of the site. Flow lines indicate this flood water flows south off of the site. We advise this must be considered in the site assessment.

Access to the site appears to be heavily affected by the on-site flood risk.

A small area of the site is unaffected by flood risk (west). We would advise that inclusion of this site in the plan is reassessed."

It forms off-site in and affects the eastern side of the site, extending west across the site as events increase. Flow lines indicate this flood water flows southeast off of the site. We advise this must be considered in the site assessment.

Access to the site appears to be heavily affected by the on-site flood risk.

A small area of the site is unaffected by flood risk (west and southwest). We would advise that inclusion of this site in the plan is reassessed.
