Plus 12m complimentary habitat buffers around locally and nationally designated sites.

Plus LWS Enhancement strategy (where appropriate/ applicable) In addition to standard requirements

Green Infrastructure/

Provide open space enhancement and management plan.

Loss of open space to be replaced by equivalent or higher quality provision.

Plus well designed GI based on Natural England's GI Principles (see Green Infrastructure)

Additionally GI provision links to strategic GI networks in wider District.

Open space provision

As per NHDC open space standards

Open space provision also seeks to:

Enhance nature depleted areas

Includes features to enhance to biodiversity e.g. such as copses, ponds, ditches, rough area.

Open space sites link to local and / or strategic green corridors (GI) seeking to compliment the Nature Recovery Network by providing habitat connectivity.

Water efficiency standard within new dwellings (See Water Use)

As per policy and building requirements

Achieves water efficiency standard of 2 credits for category Wat 01 of BREEAM

Achieves full credits for category Wat 01 of BREEAM

Adaptation to Climate Change:

Surface water drainage strategy

Surface water run-off is managed as close to its source as possible with

a SuDS strategy and a maintenance plan.

Demonstrates that scheme will not increase downstream flood risk. Scheme must achieve greenfield run-off rates. Where this is demonstrably not feasible, a minimum 50% reduction will be required.

SuDS strategy in accordance with DEFRA's non-statutory SuDS technical standards

Runoff volumes from the development to any highway drain, sewer or surface water body in the 1 in 100 year, 6 hour rainfall event must be constrained to a value as close as is reasonably practicable to the greenfield runoff volume for the same event.

SuDS strategy also addresses the 4 pillars of SuDS

achieving better than greenfield (pre-development) run off rates.

System will not discharge to combined sewers.

Land Use
