hi, I need help discharging a planning condition. the planning condition is as follows: "4. Prior to occupation, a scheme for the management of surface water must be provided to and approved by the LPA 1. Demonstration that FFLs of any habitable areas are at least 150mm above existing ground levels 2. Demonstration that the existing drainage system is adequately sized 3. CCTV survey of existing drainage system to demonstrate condition and details of any necessary remedial measures [login to view URL] that discharge rates can be reduced through the use of Sustainable Drainage Systems. Reason: In the interest of managing surface water flood risk for the lifetime of the development and to ensure the development can demonstrate a sustainable and suitable surface water outfall. In accordance with NPPF (2024) Paragraph 182 and National Standards for Sustainable Drainage Systems (2025). Typical SuDS features for a scheme of this nature includes rainwater harvesting butts or downpipe SuDSplanters." I have had a CCTV and sonar drain trace done, and I have had a an engineering company draw out the drainage plan, unfortunately the same engineering company also wrote a word-based SuDS strategy, which wasnt what the council wanted. i believe they want calculations and proof of the reduction of discharge rates compared to historic or perhaps brownfield rates. Im hoping that you can help me. i tried myseelf using AI, but i have no idea if this is right or not anyway! please help

Hi I have experience preparing UK surface-water drainage and SuDS submissions for planning-condition discharge, including runoff calculations, attenuation, existing-network review, and evidence against pre-development/brownfield discharge rates. I can review your CCTV/sonar survey, drainage plan, levels, and previous strategy, then identify exactly what is missing for the LPA response. I will prepare the hydraulic calculations, FFL compliance check, existing drainage capacity assessment, SuDS sizing, and a clear comparison of existing versus proposed discharge rates. The final package will be structured around NPPF 2024 and the 2025 National SuDS Standards, with practical measures such as rainwater harvesting or SuDS planters where appropriate. Best regards, Edwin.

Hi, There, I just saw your requirement and in my opinion you can start from basic. Ideas are something that you can identify the flood hazard area . Then you can differentiate to them into sectorise flood hazard areas into some amount to extents. Identify the surface node/coordinates in this scenario you can identify the retaintion ponds, jurisdictional waters. Flow paths is depends on water sub basin areas, which are also denoted in the drawing, the over bank depth details. Also if there any watershed map some texts some annotations. I'm a Licensed Civil Engineer working with AutoCAD efficient manner. So if you award me then I will deliver you the hydraulic drawings of flood hazards. Also can deliver the discharge rates by which the flows occurs during flood. Also how measure the recommend way to eliminate those things by discussion.

Hi there, I'm a Civil Engineer with over 12 years of experience in sustainable drainage design and surface water management. Your project clearly requires a robust, calculation-backed SuDS strategy that councils demand, not a narrative document. I understand the challenge: you've got the CCTV survey, drainage plans, and existing infrastructure details, but you need quantitative proof that your proposed SuDS features (rainwater harvesting, downpipe planters, and other measures) demonstrably reduce discharge rates below baseline or brownfield rates. This is exactly what planning conditions require. I'll deliver: - Calculated discharge rate comparisons (existing vs. proposed scenarios) - Dimensioned SuDS component specifications with hydrological performance - Proof that FFLs meet the 150mm requirement and system capacity is verified - A technical SuDS strategy document that satisfies NPPF 2024 and National Standards for SuDS With my drainage modelling expertise, I'll ensure your scheme is council-ready. Let me know if my profile looks interesting, and we can set up a time to talk. Best regards, Elijah M

I understand the urgency of discharging your planning condition for effective surface water management. My goal is to help you meet the specific requirements outlined by the Local Planning Authority. Given that you already have the CCTV survey and drainage plan, I can provide the calculations necessary to demonstrate the reduction of discharge rates, aligning with the council’s expectations. I will analyze the existing drainage capacity and compare it with your proposed Sustainable Drainage Systems features, such as rainwater harvesting and downpipe SuDS planters. This way, we can ensure compliance with NPPF guidelines and illustrate a sustainable outfall solution. Could you provide any existing data on historic or brownfield discharge rates? This will assist in making accurate calculations and strengthening your submission. Looking forward to collaborating on this vital project. Best regards, Junaid

I am interested in working on your Rural Flood Management and SuDS Design project. I can provide a practical and well-structured approach to managing surface water, reducing flood risk, and developing sustainable drainage solutions suited to rural conditions. I will focus on understanding the site characteristics, drainage challenges, catchment behavior, and project requirements before developing the design. My approach will include assessing existing drainage patterns, surface-water runoff, storage and conveyance requirements, and suitable Sustainable Drainage Systems (SuDS) measures. Depending on the site, this may include swales, attenuation areas, infiltration features, ponds, filter strips, and other nature-based solutions. I will aim to develop a design that is technically sound, practical to construct, environmentally responsible, and appropriate for the surrounding landscape. I am committed to delivering accurate, clear, and professional work within the agreed timeframe. I will maintain good communication throughout the project, respond to feedback promptly, and provide well-organized drawings, calculations, and supporting documentation as required. I would be pleased to discuss your site information and specific flood-management objectives so I can develop a solution tailored to your project.

Hi there! I think the core issue here is that councils now want to see actual numbers - the gap between what currently leaves your site and what you're proposing to retain or slow down through SuDS. Your engineering firm gave them narrative, but discharge rate calculations are what discharge rate conditions actually require. I'd work from your existing drainage survey data to establish a baseline scenario (how much runoff the site would generate under current conditions), then model how your specific SuDS features reduce that. It's straightforward hydraulic maths, but it needs to be documented clearly so the LPA can see exactly what you're achieving. That's what's probably missing. Worth a conversation if you want to walk through what data you already have - the CCTV and drainage plan should give us what we need to build this properly. Corné
