Is My Site Within A Flood Zone?

By Sadia Luckett on Sep 27, 2021 9:03:02 AM

All too often, information on whether or not your site is within a Flood Zone can be muddy and unclear, leaving you with more questions than you had to begin with.

Yet, this information is crucial to ensure the correct procedures are put in place during your planning applications and to avoid any refusals or delays to your application.

This post aims to clearly explain the types of flood zones, what they mean and detail the steps you can take to find out if your site is affected.

What Is Surface Water Flooding?

By Sadia Luckett on Aug 24, 2021 10:16:33 AM

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.

What Is Fluvial Flooding?

By Sadia Luckett on Aug 13, 2021 1:24:34 PM

When rivers and streams ‘break their banks’, the water will flow out onto adjacent low-lying areas (known as floodplains), and there are a number of reasons as to why (and how) this happens.

For example, if the runoff from heavy rain exceeds the natural capacity of the river channel, you will experience fluvial flooding. Also, if a channel is blocked or constrained – or in estuarine areas where high tide levels impede the flow of the river out to sea – your site may be vulnerable to river flooding.

Why do I need a Flood Risk Assessment in a Flood Zone 1?

By Sadia Luckett on Jul 19, 2021 3:37:05 PM

“The council are asking me to do a Flood Risk Assessment, but my property/development is in a flood Zone 1…”

It’s a common query we deal with amongst planners and architects, and one that can cause unnecessary stress, particularly if you’re not prepared.

Historically, your flood risk Zone would have been the main decider as to whether you needed a Flood Risk Assessment (FRA) or not. So, it’s understandable to assume that this is still the case.

However, legislation has changed in recent years, and although we previously had to assess the flood risk from all sources for sites in flood zone 1, we are now having to provide flood risk assessment reports for site that have been highlighted by the LPA as being at risk from other sources rather than Fluvial or Tidal.

In this post, we uncover the reasons why the council are asking you for an FRA when your property or development is in a Flood Zone 1.
