Therefore any additional runoff from the impermeable areas will be small and more than adequately managed by the swale system outlined in Section 6.0. As such there will be no impact on the nearby watercourses and neighbouring sites as a result of the proposed development. In addition, the pragmatic approach to the design of the swales will provide an improved storage and interception capacity and will reduce any risks to adjacent sites from runoff, when compared to the pre-development situation.

As such the swales have ample capacity to contend with runoff from the impermeable areas of the site under rainfall events in excess of the 1 in 100 year storm. Despite the relatively large capacity of the swales there is still a risk that shallow surface water pooling could occur across the site in events in excess of the 1 in 100 year storm. The drainage system proposed has been specifically designed for the volume of surface runoff resulting from the solar panel foundations and inverter stations. Therefore, any unauthorised future connections into the site drainage network will potentially overload the system. Therefore any future development on the site, beyond the current proposal, should be suitably planned and considered, especially if new impermeable areas are to be introduced to the site. As long as these factors are considered in the design of the development there is the capacity to manage any associated residual risks.
