Comrie flood protection scheme

Background

Comrie has experienced a history of flooding from the Water of Ruchill, the River Earn and the River Lednock. The most recent significant flood events occurred in January 1993, February 1997, December 2006 and in August and November 2012.

In 2013, the Council completed the following flood protection works to reduce the risk of flooding to the Dalginross area from the Water of Ruchill:

  • Rock armour protection to the river bank on the Water of Ruchill at Ruchilside;
  • The removal of the old flood embankments at Tomnagaske;
  • A new flood embankment at Camp Road.

The standard of protection provided by these new works against flooding from the Water of Ruchill is equivalent to the predicted 1 in 100 year return period flood, with an allowance for climate change. This corresponds to the flood event that has a 1% chance of being exceeded in any one year.

However, these flood protection works do not address the remaining flood risk from the River Earn or the River Lednock, or the combined risk from all three rivers.

The Flood Risk Management (Scotland) Act

Comrie is located in the River Earn catchment within Potentially Vulnerable Area 02/08/13.

Actions to manage the risk of flooding in the area have been included in the updated Tay Flood Risk Management Plan and the existing  Tay Local Flood Risk Management Plan (PDF) [12MB] . These actions include a wider flood protection scheme but, due to the cost and extensive work involved, this is likely to be some time away. Other actions have therefore also been included to support the community in the meantime. Details of all of these actions can be viewed in the preceding Plans and in the public exhibition presentation (PDF) [459KB] .

The flood protection scheme has been included within the national priority list of flood schemes. The Scottish Government and the Council have agreed in principle to fund the scheme. The Scottish Government will contribute 80% of the overall capital cost and the Council will contribute the remaining 20%.

The proposed scheme

The proposed scheme is designed to protect 189 homes and businesses, some of which have previously been affected by flooding in Comrie. The scheme will significantly reduce the flood risk to those properties from three rivers; the River Earn, the River Lednock and the Water of Ruchill. Once complete, it will provide a standard of protection equivalent to a flood event with 0.5% chance of occurring in any given year (a 1 in 200 year flood event), with a further factor of safety (known as 'freeboard') to allow for the uncertainties involved in flood estimation and other physical factors such as wave action. 

The flood scheme involves the construction of flood walls and embankments. Details of the proposed scheme can be viewed on our scheme documents page.  

Current position

We have secured the necessary statutory approval for the scheme under the Flood Risk Management (Scotland) Act 2009. The proposed scheme was confirmed without modification by the Council's Environment and Infrastructure Committee on 18 August 2021. The Scottish Ministers directed that planning permission was deemed to be granted on 16 December 2021.

The detailed design of the flood scheme was concluded in spring 2023.

The exercise to procure a contractor for the main works is ongoing. This is taking longer than expected, but we are aiming to have appointed a contractor by summer 2024, with the main construction works to follow on at the end of the summer. 

We will continue to keep you updated as the main construction works approach.
