£500 – £750 (included with our Full Drainage Strategy & Design)
Many North West planning authorities now require the NW SuDS Pro-forma for major developments and sites in Critical Drainage Areas, and applications without it can be refused validation. We complete all eight sections, backed by the calculations and evidence the LLFA expects. If you already have a drainage design, we check it for gaps, such as interception or discharge hierarchy, and handle the first round of LLFA comments.
All prices are guide prices; final quotes provided following initial site review.
