Development proposals which are identified as likely to cause harm to air quality or could expose occupiers and users of the building to poor air quality will be resisted unless appropriate mitigation measures are proposed to reduce the impact to acceptable levels.

Measures to improve air quality should be implemented on-site however where it can be demonstrated that on-site provision is impractical or inappropriate, off-site measures to improve local air quality may be acceptable, provided that equivalent air quality benefits can be demonstrated.

Water Pollution

New developments should not pose an unacceptable risk to water quality and developments which have the potential to adversely impact on water quality, in the opinion of Hackney and the Environment Agency, will be required to provide appropriate mitigation to alleviate the risk.

Source Protection Zones (SPZs) should be taken into account whenconsidering the environmental impact of a development.

Contaminated Land

For development proposed on contaminated or potentially contaminated land, a desk study and site investigation in line with the most up-to-date guidance will be required and remediation proposals agreed to deal with any identified contamination.

New development should address risks to sensitive receptors (both on and off site) from land contamination through proportionate action(s) before and during construction and during operation where appropriate, planning conditions, over the lifetime of the development.

Development which proposes potentially contaminating or polluting activities, or which is located in close proximity to hazardous installations, must incorporate mitigation for harmful effects to people and the environment and where considered necessary, provide monitoring of any impact.

Noise and Vibration

Noise-sensitive development should be located in areas where occupiers will not be exposed to significantly adverse noise levels. Where new noise-sensitive development is proposed in proximity to existing noise-generating uses, the applicant will be required to carry out a noise assessment and demonstrate how adverse effects will be effectively mitigated without harming the continued operation of existing uses.

Development in any location will only be permitted where it can be demonstrated that the noise generated by the development is effectively mitigated to prevent adverse impacts on health and quality of life. The impact of noise generated by the demolition and constructions phases of development must also be minimized.

All residential development proposals shall minimise the potential adverse noise impact on and between dwellings through housing layout, design and materials. New development will only be permitted where the locations of lift and circulation mitigate the impact.
