Received an LLFA Flood Risk Objection?
A Lead Local Flood Authority objection to your planning application is a serious issue that needs to be addressed promptly and professionally. LLFAs are statutory consultees on flood risk and drainage matters, and their objections carry significant weight with Local Planning Authorities — applications are unlikely to be approved while an LLFA objection remains outstanding.
We specialise in reviewing LLFA flood risk and drainage objections, identifying the technical issues that need to be resolved, and preparing comprehensive responses that address the LLFA's concerns and provide the additional evidence needed to withdraw the objection.
With over 17 years' experience working with LLFAs across England and Wales, we understand what they are looking for and how to respond effectively. We've resolved hundreds of LLFA objections across all types of development and all types of drainage and flood risk issue.
