The screenshot below is taken from the Non-Statutory Technical Standards for Sustainable Drainage by LASOO (Local Authority SuDS Office Organisations. The reason for showing this extract is to demonstrate what information is required to be produced for a Pre-app or Outline planning application.
All of this information can take a considerable time to produce so you should engage with your preferred drainage designer as early as possible to avoid lengthy delays to your project.
Engaging with drainage designers at the earliest opportunity can significantly influence the outcome of a development. Here, we explore the benefits and potential disadvantages of early consultation with drainage designers.
Benefits of Early Consultation with Drainage Designers
Optimized Design and Cost Efficiency Early involvement of drainage designers allows for the optimization of the overall site design. By understanding the drainage requirements from the outset, developers can integrate sustainable drainage solutions (SuDS) that align with the site's topography and soil conditions
Enhanced Planning and Approval Process Engaging drainage designers early can streamline the planning and approval process. Detailed drainage plans that meet regulatory standards can be prepared in advance, reducing the risk of delays caused by non-compliance issues
Improved Environmental Impact Early consultation allows for the incorporation of environmentally friendly drainage solutions, such as green roofs, permeable pavements, and retention ponds
Risk Mitigation Identifying potential drainage issues early in the project can help mitigate risks associated with flooding and water damage
Disadvantages of Early Consultation with Drainage Designers
Initial Costs Engaging drainage designers early in the project can incur additional upfront costs. These costs include fees for detailed site assessments, design consultations, and the preparation of comprehensive drainage plans
Complexity in Coordination Early involvement of drainage designers requires effective coordination among various stakeholders, including architects, engineers, and planners
Potential for Over-Engineering In some cases, early consultation may lead to over-engineering of drainage solutions, resulting in higher costs and unnecessary complexity
Conclusion
While there are some potential disadvantages to early consultation with drainage designers, the benefits far outweigh the drawbacks. By engaging drainage designers at the earliest opportunity, developers can optimize their designs, streamline the approval process, enhance environmental sustainability, and mitigate risks.
Ultimately, early consultation with drainage designers is a strategic investment that can lead to more successful and sustainable development projects.
