Which Types of Developments in Oswaldtwistle Require a Flood Hazard Survey Report?

We prepare flood hazard survey reports in Oswaldtwistle for a variety of developments where planning rules require them, including:

• Developments within Flood Zones 2 or 3 – Locations with a higher risk of river or coastal flooding.
• Sites larger than one hectare – Regardless of official flood zone classification.
• Projects near rivers, reservoirs, or the coast – Where proximity to water increases flood hazard potential.
• Sites with a record of surface water flooding – Even if outside mapped flood zones.
• Developments where the local planning authority mandates a survey – As part of planning approval conditions.

How Much Does a Flood Hazard Survey Cost in or Around Oswaldtwistle?

The cost of a flood hazard survey in Oswaldtwistle ranges from £500 to over £2,000, depending on the size of the site, its flood zone classification, and the complexity of the analysis.
