• A site-specific Flood Risk Assessment and Sequential Test is required, in consultation with the Environment Agency (if applicable) or Lead Local Flood Authority if the proposal is:
• A development site of 1 hectare or over within Flood Zone 1
• A site within Flood Zones 2 or 3.
• A non-householder application on a site within 1% AEP (Annual Exceedance Probability) plus 70% climate change fluvial flood extent and/or the 0.1% AEP RoFSW (Risk of Flooding from Surface Water) flood extent
• Within an identified critical drainage area (as identified by LB Barnet)
• Where a site may be subject to a source of flooding other than from rivers and its development would introduce a more vulnerable use.

14. Ecological Assessments: An ecological assessment will be required to evaluate the baseline habitats present, identify, quantify and evaluate potential effects of development-related actions on habitats, species and ecosystems. Appropriate assessments are required for all developments, where they are in proximity to known habitats of a protected species and also required for developments affecting sensitive areas (including for example, open landscape, sites adjacent to a river corridor, sites of nature conservation importance and statutory protected sites).

Details of how the protection of biodiversity and habitats shall be achieved.  The submission shall also include proposals for long term maintenance and management to secure the required biodiversity gains (30 years).

Proposals involving demolition and/ or complete or partial removal of a roof or removal of mature trees will require a Preliminary Bat Roost Assessment.

All developments, in accordance with the London Plan, unless specifically excluded is required to submit an Air Quality Neutral Assessment (AQN Assessment) demonstrating how the Air Quality Neutral benchmarks in this guidance will be met. There is a simplified assessment for minor development.

All large scale developments subject to an EIA will need to demonstrate how they have used an air quality positive approach.
