SuDS for Lead Local Flood Authorities

JBA Consulting - surface water flooding

This is a new course that can be configured to suit those wishing to attend by choosing modules relevant to you. It can be delivered as a one or two-day course and we would recommend a maximum of three modules per one-day course to allow time for discussion and exercises.

Register your interest

  • Lead Local Flood Authorities
  • Other Risk Management Authorities working with Lead Local Flood Authorities
  • Local Planning Authorities wishing to gain a greater insight of the LLFA statutory consultee role
  • Developers and consultants wishing to gain a greater insight of the LLFA statutory consultee

Depending on which modules are chosen, following the course attendees should have an understanding of:

  • Relevant national and local legislation, policy, standards and guidance supporting the LLFA statutory consultee role (and in Wales only the SUDS Approving Body role)
  • The performance and key features of SuDS systems,
  • The wider benefits of SuDS include amenity, ecology, water harvesting and green infrastructure. You will discuss the practical application of SuDS in the context of the emerging guidance and legislation.
  • Standard techniques for estimating greenfield runoff rates, development runoff and storage volumes
  • Approaches to hydraulic modelling and different types of model
  • What should be in a FRA/ SWDS and key things to check when auditing them

Jennifer Hill BSc MSc MCIWEM C.WEM

Jennifer specialises in urban catchments – recognising the need to treat the urban environment as an integrated catchment. Jennifer has a keen interest in connecting the water cycle and the benefits that SuDS and Water Sensitive Urban Design can bring to flood risk management, water resources, water quality, amenity and climate change adaptation. As part of Jennifer’s work on Surface Water Management Plans she has become experienced in leading Communication and Engagement between multiple project partners and members of the public.

Thomasin Sayers BA (Hons)

Thomasin has worked with lead local flood authorities and the National Flood Forum throughout her career. She also worked on an extensive range of projects and has expertise on the planning process of sustainable drainage systems, Strategic Flood Risk Assessments, Surface Water Management Plans, and national Flood Risk Management Plans.

Having also aligned local authority planning processes with national policy and supported the implementation and adoption of sustainable drainage systems and green infrastructure, she has invaluable experience in relation to applying national and local policy, guidance and legislation.

An overview of the Statutory Consultee role and relevant policy, guidance, standards and legislation

Background to the Statutory Consultee role

  • Relevant legislation and national policy, standards and guidance
  • Local policy and guidance
  • Stages of the planning process and LLFA involvement (from policy to detailed Planning Application)

An overview of SuDS

  • What are they?
  • What benefits can they provide? Examples of best practise
  • What are the perceived and actual constraints?
  • Who maintains them and how?

Requirements for Flood Risk Assessments (FRAs) and Surface Water Drainage Strategies (SWDSs)

  • Background to the Statutory Consultee role
  • Relevant national and local guidance
  • What to expect at different stages of the planning process
  • Overview of interception, attenuation and long-term storage
  • Accounting for urban creep and climate change
  • Challenges for SuDS design: Adoptability of sustainable drainage features

Local flood risk and planning: identifying and mitigating flood risk

  • Identifying flood risk from local sources: what information is available, at which stage of the planning process and how to identify if more information is required
  • LLFA input to LPA Local Plan evidence bases and planning policy development, including Strategic Flood Risk Assessments and the latest NPPF refresh requirements
  • Options to mitigate local flood risk on site/ provide wider betterment/ take a risk based approach to development master planning

Overview of hydrology and modelling for development planning

  • Standard techniques for estimating greenfield/ brownfield runoff rates, development runoff and storage volumes
  • Differences between urban and rural catchments
  • River hydrology
  • Types of model (fluvial, pluvial, sewer scenarios), overview of approaches and proprietary software (TUFLOW, InfoWorks, WinDES, Flood Modeller Suite, HEC-RAS, JFlow)

Key points for auditing (relating to the new LCC developer checklist for SuDS)

  • Reviewing a FRA
  • Reviewing a SWDS
  • Reviewing hydrological calculations
  • Reviewing hydraulic models
  • Review exercise using a local case study
