St Austell Bay Resilient Regeneration (StARR) Project
The St Austell Bay Resilient Regeneration (STARR) project aims to reduce flood risk to communities living and working in the St Austell Bay area, particularly in Par and St Blazey. The proposed scheme will bring additional benefits to the area by encouraging investment and making St Austell Bay a better place to work, live and play.
To progress the development of StARR we are working in partnership with:
- Cornwall Development Company
- The Environment Agency
- South West Water
- The University of Exeter and
- Westcountry Rivers Trust.
Details of the scheme are available on the STARR Project Plan infographic
You can find out more about the works to be undertaken on the STARR Project Visualisation

WestCountry Rivers Trust:
The St Austell Bay Resilient Regeneration Project (StaRR) is a £20M flood alleviation and regeneration scheme led by Cornwall County Council.
Funding is being sought for this innovative scheme aiming to work across the whole of the Par and Sandy River Catchments to reduce flood risk to communities living and working in the St Austell Bay area particularly the people of Par and St Blazey. Works will be delivered in partnership between Cornwall County Council, The Environment Agency & Westcountry Rivers Trust, South West Water, the University of Exeter & Cornwall Development Company. Planned implementation is 2017-2020. https://www.cornwall.gov.uk/environment-and-planning/countryside/estuari... bay-%20resilient-regeneration-starr-project/">Find out more here
Westcountry Rivers Trust’s role within the project is to work with local communities in the upper catchment to develop and deliver Natural Flood Management solutions.
St. Austell Bay Resilient Regeneration (StARR) project
Overview
The St. Austell Bay Resilient Regeneration (STARR) project aims to reduce flood risk to over 800 homes and businesses in Par and St. Blazey.
The scheme will bring additional benefits to the area by encouraging investment and making the area a better place to work, live and play.
We are working in partnership with Cornwall Council, University of Exeter, South West Water and Westcountry Rivers Trust.

Why Par and St. Blazey needs a flood scheme
Many of the homes, businesses and infrastructure of the towns sit in the bed of a former estuary, boats used to sail up and dock at Ponts Mill at the base of Luxulyan Valley. However, over the last few hundred years, the former estuary has become silted up with material bought downstream as a result of tin and clay mining in the upper River Par catchment. The natural river has also been raised up and split in two to drain through the town in the form of the River Par and Treffry Canal which adds to the flood risk.
Par and St. Blazey are affected by 3 different types of flooding:
Surface water flooding - when rainwater doesn’t drain away through the drainage systems or soak into the ground and lies on or flows over the ground
River flooding – when a river or stream exceeds its capacity and overtops its banks. Also known as fluvial flooding.
Tide-locking – when a high tide causes water to back flow. This happens on the Par River, St. Blazey Stream and Polmear Stream.
How the scheme will work
The Par and St. Blazey Flood Defence system is one of the most complex and highly maintained in Cornwall. It is maintained by a number of different organisations and individuals – the Environment Agency, Cornwall Council, South West Water and individual riverside property owners. However, these defences are now quite old and cannot cope with the levels of flooding that are now experienced. The project will repair these existing defences and install more to cope with new demands put on the system to ensure that the chronic flooding problem is now dealt with. We will also be using new innovative natural flood management measures such as rain gardens to store and slow the flow of water.
