Drainage Planning Consultations

 

Engineering Services are consulted on all planning applications in the Lidsey Treatment Catchment area and all applications of more than two units in the remainder of the District, or wherever watercourses are affected.

Applicants are encouraged to consider surface water drainage at the earliest stage of the planning process.  It is not uncommon for pre-commencement conditions to be requested on Planning Applications. It is wise to ensure that any site can be effectively drained (using SuDS principles) before making an application, so that an applicant can be confident that likely Planning conditions can be met.

Applicants are guided to check the Supplementary Requirements for Surface Water Drainage Proposals before making a submission.  It is worth highlighting that winter groundwater monitoring and infiltration testing are fundamental parts of the design process.  Both are specified within our standard conditions.  A failure to understand these requirements or adequately complete the monitoring/testing can result in extensive delays to projects due to the requirement that both are done in winter conditions.  It is strongly recommended that applicants contact this department at land.drainage@arun.gov.uk before undertaking or funding any monitoring or testing, to ascertain exactly what the requirement is for their particular site, as this will vary depending on the size of the development and its location.

In addition, applicants should complete and submit a copy of our Drainage Checklist when looking to discharge conditions or avoid pre-commencement conditions.
