Simply put, surface water flooding occurs when the volume of rainwater falling is unable to drain away through existing drainage systems or by filtering into the ground. As a result, the water lies on the ground and may begin to flow – causing localised floods, which can affect your developments.
Typically, surface water flooding is caused by the amount of rainfall and the high speed at which it hits the ground. This causes a build-up that prevents the existing drainage systems from draining it.
Surface water flood events usually have localised effects, therefore only impacting properties in a close proximity to the resulting floods. In these instances, it may only affect those properties and the surrounding areas for a short period of time.
However, due to the sporadic and intense nature of these surface water flood events, the damage can be extensive and affect huge areas, being in-situ for prolonged periods of time.
So we know that surface water flooding can be hugely disruptive to your new development(s).
Now let’s see how it could affect you and your future planning applications and what you can do to prepare for it.
