FRA & SUDS Reports for planning

"Great news. The Council have come back and agreed that we’ve discharged the necessary planning condition related to the flood assessment and SuDS design. Thank you for the work that you and the team have put in to help ensure this successful outcome. I really appreciate the speed and responsiveness that everyone at Jomas have shown, and of course, should I ever have further need for similar or related services, Jomas Associates will be my first call."
