Water is one of the most influential factors in land development. Whether you’re planning a new build, barn conversion, extension, or commercial project, understanding flood risk and surface water management is essential for securing planning permission and delivering a safe, sustainable design.

​

At Barndwell, we provide professional hydrology services, including Flood Risk Assessments (FRA) and Drainage Strategies, to support planning applications across England and Wales. Our reports are clear, compliant, and tailored to your site — helping your project progress smoothly from concept to construction.

​

Why Hydrology Matters in Development

 

Local planning authorities require robust hydrological evidence to ensure new developments:

• Are safe from flooding

• Do not increase flood risk elsewhere

• Manage surface water sustainably

• Comply with national and local planning policy

• Integrate SuDS (Sustainable Drainage Systems) where required

 

A well‑prepared FRA or drainage strategy is often the difference between planning approval and refusal.
