Flood Risk & Drainage

Flood Risk & Drainage

Water is one of the defining challenges for the future of the built environment. Flood risk, drainage capacity and climate change are increasingly shaping how land is acquired, planned, designed, funded and managed.

GIA helps clients understand these risks early and respond with confidence. Our flood risk, water, climate adaptation and resilience advice supports development, investment and asset strategy from acquisition and feasibility through to planning, design and long-term resilience.

We provide clear, evidence-based insight into current and future flood risk, surface water management, sustainable drainage, blue-green infrastructure and climate adaptation. Our advice helps clients identify constraints, unlock opportunities, support planning submissions and protect long-term asset value.

By combining technical expertise with planning insight, spatial analysis and clear visual communication, we translate detailed water and climate information into practical, decision-ready advice for developers, landowners, investors, asset managers and project teams.

Whether reviewing a site for acquisition, preparing a planning application, developing a drainage or sustainable drainage strategy, assessing future climate risk or managing water-related risk across an asset or portfolio, GIA provides advice that is commercially focused, technically robust and aligned with the wider development process.
