Heritage Statement:
Required in a conservation area, for a listed building or where development would affect any other heritage asset or their setting including a positive building, locally listed building, area of archaeological significance.

The Council has produced specific guidance on requirements for Listed Building applications
Ecological Assessments:
Plans should show any significant wildlife habitats or features and the location of habitats of any protected species. Applications for development that will affect sensitive areas must be accompanied by ecological assessments and include proposals for long term maintenance and management.

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).

This information might be incorporated into an Environmental Statement, if one is necessary.

Appropriate ecological assessments will be required for all developments near known habitats of any protected species, or where there is a reasonable likelihood of a species being present. Any demolition will require a Preliminary Bat Roost Assessment. This Assessment will also be required for partial or full removal/ replacement roof on a householder application.

Further advice on protected species and habitats can be obtained from Natural England.

A biodiversity net gain assessment shall be undertaken using the latest DEFRA biodiversity metric for the site.

From November 2023, Environment Act 2021 requires all schemes will have to deliver at least 10% biodiversity net gain on the baseline survey and that this will be secured for at least 30 years. London Plan 2021 Policy G6 requires all development to deliver biodiversity net gains which shall be calculated in the same way.
Tree survey and arboricultural statement:
Required where trees are located within 15m (edge of trunk) of development (on the site or adjoining land, including street trees). A plan to show their location and measures to protect them during development is also required.

Also required where there are ground level changes and/ or excavations including for enabling works.
Open Space, Landscaping and Urban Greening Factor Statement: Where provision for biodiversity net gain is a requirement the soft landscape must be designed to facilitate the delivery of biodiversity net gains and amenity.

Noise Risk and/or Impact Assessment:
A Noise Assessment is required for proposed development which is likely to be exposed to significant noise and/or vibration or cause a noise and/or vibration impact. For all noise sensitive and noise creating developments the Council will refer to the standards set out for internal and external noise levels in BS8233 (2014) and to the approach of BS4142:2014 (2019). As well as the Noise chapter of the PPG. Such assessments should be provided at application stage for sites where the noise impact is high
Air Quality Assessment:
An Air Quality Assessment is required where development could potentially contribute to a worsening of local air quality eg Major and large scale commercial/ industrial use, CHP or biomass boilers. For minor development one will be required in areas of poor air quality or where there is a significant risk development will fail to satisfy requirements of London Plan Policy SI 1 (B1)

All development, 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.
