5.6 SUSTAINABLE DRAINAGE
Comments that more is needed in the SPD on flooding and wastewater to fulfil Local Plan, SEA/SA and NPPF

Worked in parallel with SCDC, Anglian Water, RLW Estates and Urban & Civic to shape planning applications and related water quality aspects of foul water.

Earlier work on Denny St Francis Water Cycle Strategy identified key constraints and opportunities for SPD to address, but they do not appear to have made their way into the SPD.

Share objective of ensuring SPD delivers sustainability outcomes and fulfil Local Plan, SEA/SA and NPPF.

Advised on scope of SA - that significant environmental issues (flooding & wastewater) needed to be addressed.

Following issues need filling & strengthening:
* Cam Washes SSSI - only a single mention yet significant site
* Use of flood maps and need for SFRA
* Flood risk and on site hazards - effects of flood defences
* Insufficient SFRA information in Local Plan evidence base
* Climate change and infrastructure to adapt to it
* Missing flood risk sequential approach
* Contribution to flood risk infrastructure for upkeep
* Status of comparable constraints - Denny Abbey has assessment of the setting - similar approach needed for water in respect of evidence base, involvement of statutory consultees, spatial approach, follow national policy
* Spatial illustrations need to have regard to avoiding and managing flood risk
* Welcome SUDs but blue infrastructure is wider
* Support clear infrastructure requirement for water usage
* SPD needs to fulfil its own requirements - flood risk management & waste water infrastructure (include a new section)
