Why Is Flood Risk Mapping Important in Greater Manchester?

Flood risk mapping in Greater Manchester is often a legal requirement for developments located in or near designated flood zones or in areas with limited drainage capacity.

Accurate mapping allows planning authorities to understand how a proposed development will manage flood risk in Greater Manchester without creating issues for surrounding areas, ensuring compliance and safety.

Which Developments in Greater Manchester Require a Flood Risk Mapping Report?

We produce flood risk mapping reports in Greater Manchester for a wide range of developments where planning regulations require them, including:

• Sites within Flood Zones 2 or 3 – Areas with a higher probability of river or coastal flooding.
• Land parcels over one hectare in size – Regardless of official flood zone classification.
• Projects near rivers, reservoirs, or coastal areas – Where proximity to water increases flood potential.
• Locations with a history of surface water flooding – Even if outside designated flood zones.
• Developments where a local planning authority mandates mapping – As part of the approval process.

How Much Does Flood Risk Mapping Cost in or Around Greater Manchester?

The cost of flood risk mapping in Greater Manchester ranges from £600 to over £1,200, depending on the site’s size, flood zone status, and the complexity of the assessment.

Costs are influenced by factors such as the need for hydraulic modelling, access to historical flood data, drainage capacity evaluations, and any additional inspections or recommendations.
