PPS25 Past, Present & Future
PASTPPG25 - July 2001 to November 2006
PRESENTPPS25 – Introduced December 2006. Updated March 2010 (also Coastal Supplement)PPS25 Practice Guide - Introduced June 2008. Updated Dec 2009
FUTUREFloods & Water Management Act 2010 – New ResponsibilitiesNational Planning Policy Framework

PPS25 Principles
Hierarchy of Flood Risk Management;
ASSESS > Flood Risk Assessment at Regional, Strategic & Site-specific level;
AVOID / SUBSTITUTE > Sequential Test & Sequential Approach;
CONTROL / MITIGATION > FRA considers lifetime of development, climate change, residual risks.
![Page 9: Flood Risk Standing Advice](https://reader034.fdocuments.net/reader034/viewer/2022042619/58a2bc941a28ab8e608bbded/html5/thumbnails/9.jpg)
Sequential Test
Objective: to steer new development to areas of lowest flood probability (Zone 1)
Applied “at all levels of planning”;
Regional Spatial Strategy
Local Development Framework
Informed by RFRA, SFRAs & site-specific FRAs;

Is it Appropriate?
![Page 21: Flood Risk Standing Advice](https://reader034.fdocuments.net/reader034/viewer/2022042619/58a2bc941a28ab8e608bbded/html5/thumbnails/21.jpg)
Sequential Test
Applies to all development proposed within FZ2 or FZ3 except:-
• ‘Minor’ development
• Change of Use
• Replacement of single dwelling
• Development in Regeneration area where work has begun
• Wind turbines
Planning Applications – “The developer will need to provide
evidence to the LPA that there are no other reasonably available sites where the development could be located. The LPA applies the Sequential Test to the application.”
![Page 22: Flood Risk Standing Advice](https://reader034.fdocuments.net/reader034/viewer/2022042619/58a2bc941a28ab8e608bbded/html5/thumbnails/22.jpg)
Sequential Test
What is ‘reasonably available’?;
Undefined but linked to PPS3 guidance on ‘deliverable’ & ‘developable’:-
Be Available – reasonable prospect that site is
available;
Be Suitable – the site offers a suitable location for development now and would contribute to the creation of
sustainable, mixed communities;
Be Achievable – there is a reasonable prospect that
development will be delivered on the site within five years.
![Page 23: Flood Risk Standing Advice](https://reader034.fdocuments.net/reader034/viewer/2022042619/58a2bc941a28ab8e608bbded/html5/thumbnails/23.jpg)
Sequential Test
Various appeal decisions have shown that:-
The fact that an applicant does not own any other land is not a direct consideration;
Applications can be refused on ST grounds even when FRA is acceptable and EA do not object;
Housing developments can be resisted where an LPA
can demonstrate 5 years housing supply in FZ1;
Applications can be refused solely on the basis of
historical windfall rates of housing in lower risk Flood Zones, where relevant.

Exception Test
Three parts:
A) Wider sustainability benefits > flood risk
B) On brownfield unless no other reasonably available
brownfield sites
C) Safe & won’t increase flood risk elsewhere (FRA)

Flood Risk Assessment
Site-specific – Applicants responsibilityDemonstrate development safe and won’t increase flood risk elsewhere; Should be proportionate to the scale, nature & location of the development;Annex E of PPS25 sets out minimum requirements;
Climate Change;
Residual risks; Flood PlanAll sources of flooding
identifying opportunities to reduce flood risk, enhance biodiversity and amenity, and seek collective solutions to managing flood risk.

EA Flood Map
Easter 1998 floods response –land vulnerable to flooding
1999 basic Indicative Floodplain Map issued
2004 Flood Map – National Dataset – DTM, FEH, Flood Zones 2 & 3 refined
Limitations: no defences, channel capacity, in-channel structures, min 3km2 catchment size
Updated quarterly – only improved modelling, or successful challenge
EA Flood Models
Best information ‘main river’– for flood warning, scheme feasibility/ design, asset assessment - not always appropriate or available for development design

The Future
Floods & Water Management Act:-
LLFAs responsible for preparing & implementing
strategies for managing risk from groundwater, surface water & ordinary watercourses;
EA powers for coastal erosion risk management;
Risk based approach to reservoir safety;
Encourage uptake of SUDs by removing automatic right to connect to sewers;
SUDs Approval Boards (SABs) to adopt SUDs for new
developments & redevelopments.
