Once you have received their approval, you can dig a hole up to 5 feet deep. If you intend to dig a hole that is deeper than this, you will require to receive a special permit before proceeding.

This requirement applies regardless of where you intend to dig the hole.

Even if you want to excavate your front yard, the first step that you must undertake is obtaining permission from the Common Ground Alliance. The ‘5 feet deep’ rule still applies.

There are two ways to reach CGA. First, you can call them directly using the number 811. Once you call, CGA will then contact the local utility operators in your area of residence.

Alternatively, you may opt to visit their website and then directly make an online application from there.

After you have selected your state, you will receive an online ticket that will come in handy whenever you want to track the progress of your application.

The application may take a couple of days before it is officially completed.

How deep can I dig without a permit in the UK?

In the United Kingdom, the laws are more stringent, unlike in the USA.

You must stick to the ‘100 mm or less’ rule to dig without a permit.

That is way stricter compared to USA’s ‘5 feet deep’ rule. However, the permit is a necessary evil.

Obtaining a permit is not a punishment! It serves the greater good in society as it ensures that you don’t disturb the ground level, affecting the utilities in the area.

However, it’s noteworthy that there are various instances when you will not need to obtain a permit before you can dig in the UK. These include:

Likewise, it is important to stress the various instances when you must obtain a permit before you think of doing any excavation in the UK.

Besides holes that are deeper than 100mm, other instances include:

  •  Refurbishing a playground.

Do I need planning permission to excavate my Garden?

In most cases on How Deep Can I Dig In My Backyard, gardening and landscaping works do not need planning permission.

However, you may need planning permission to excavate your Garden in certain instances.

The reason is simple. You do not want to interfere with underground utilities or affect your neighborhood with your excavation activities.

In the US, several rules are applicable. For instance, you must refrain from digging too close to the utilities or their markings.

Generally, you should maintain at least 18 to 24 inches between them.

Likewise, you are prohibited from using heavy machinery such as excavators near these utilities.

Instead, you can opt to use smaller equipment like a shovel.

In various instances, you might need a scanner to locate the depth of service lines, water pipes, or other utilities.

Like in the US, you may need planning permission if you intend to excavate your Garden and reside in the United Kingdom.

An example is where a homeowner wishes to pave their front garden without using a permeable material, and the paving is more than 5 square meters.

The requirement to seek planning permission in such a situation came about following the 2007 big floods in the UK.

The reason was that converting gardens into driveways significantly contributed to the floods since the runoff water went into storm drains whenever it rained.

The planning policy requires that permission be sought regardless of the paving, the back garden, or the drive.

There are instances when you will not need planning permission.

These include when you want to install timber garden structures such as sheds and outbuildings. Such activities are permitted under the ‘permitted development rights.’
