How Much Does a Flood Risk Assessment Cost?

What is Flood Risk Assessment?

A Flood Risk Assessment is a thorough study of a site by preparing a report that looks at all the flood dangers and the safety concerns. It is a report mainly prepared to look at the risks earlier and highlight the precautionary measures to keep the area safe in case of floods.

People become worried about the cost. However, the costs associated with flood risk assessment always confuse people. You can’t get an accurate price for flood risk assessment as the cost of the assessment varies depending on different factors. This blog guide helps you gain the cost that you have to spend on your site from any risk that may arise because of the flood.

Flood Risk Assessment Cost

Low Charges: Minor developments with fewer than 9 dwellings usually start from the cost of 650 pounds.

High Charges: In major developments, the starting cost of 10 dwellings or more is approximately 1850 pounds.

The average cost of flood risk assessment lies approximately between 299 pounds and 899 pounds.

Drainage and Other Major Costs

If the major developments are considered, the huge amount of cost should be carried for the proper drainage system as well. Here are the prices mentioned:

• Usually, 2000 to 3000 pounds are charged for the small sites (that include fewer than 10 homes)

• For the commercial areas, the budget should be about 3600 pounds (includes ten to fifteen homes)

• For a larger commercial site, the cost is nearly 4800 pounds, covering 50 to 200 homes.

• The cost is 7200 pounds or more for 200+ homes.

• Depending on the location, the prices may vary in certain cases.

Other Costs

Always keep in mind the additional costs that you have to spend on the watercourse modelling, infiltration testing, sewer records and the developer enquiries. The most expensive one is the watercourse modelling, which starts at approximately 12,000 pounds. The range of infiltration testing is from 1000 pounds to 3000 pounds, while the developer enquiries revolve around 350 pounds.

Factors Affecting the Cost

Doing the primary assessment of the flood won’t cost you so much, while doing the detailed assessment can cost you several thousand pounds. Take a look at how each factor contributes to the cost:

Flood screening study: This is the first step of doing the desk study that involves analysing the data taken from the planning authorities and the environmental agency. How the main infrastructure may be affected is also discussed in this study. This step reduces the overall cost as it identifies that the site has low risk, or you have to go for the detailed assessment.

Flood Scoping Study: After getting the quality assessment in the early step, the flood scoping study provides in-depth information about the historical flood events, the sources, and any other issues related to the drainage. Flood scoping requires the flood screening study for preparing the proper risk plan.

Additional Tests: The additional tests, such as the sequential and exception test, contribute to the additional cost of the assessment. The sequential test is conducted in the flood zones 2 and 3 because the risk factor of the flood is lower in the flood zone 1. If a suitable safety site is not found, an exceptional test is conducted.
