A Drainage Assessment (DA) is required by PPS 15 if the proposed development comprises 10 or more dwelling units, exceeds one hectare or involves a change of use exceeding 1000 square metres. You may also be asked to provide a DA if pluvial flooding is predicted at your site or where run-off from the development may adversely impact upon other development.
We will provide you with a free lump sum quotation to undertake the DA and will not add any additional costs at a later stage. We will meet your deadline and we will revise the DA report for free if required by Rivers Agency. Our DAs are tailored to the project, minimising necessary mitigation measures and optimising the area of the site that can be developed.
We will visit the site, assess it for fluvial, pluvial and historic flooding, produce a DA report in compliance with PPS 15 and seek agreement with Rivers Agency, holding meetings with Rivers Agency and Planners as necessary at no extra cost.
