Before going ahead with any large-scale proposals, the Government must commission a Strategic Environmental Assessment (SEA) Report. This is a detailed study used to assess how large-scale proposals, such as new towns, could affect the environment and local communities. It looks at a wide range of factors including transport, flood risk, air quality, landscape, and overall sustainability.
The purpose of an SEA report is to compare different locations in a fair and consistent way, helping decision-makers identify which options offer the greatest benefits and the least harm.
The summary below highlights the key findings from that report and explains why Adlington was not chosen.
1. LIMITED NATIONAL ECONOMIC IMPACT
The most important factor was that Adlington was not seen as a location that could deliver major economic growth at a national level.
Other shortlisted locations, particularly those in large cities, were able to:
- Support more jobs and investment
- Provide better access to employment hubs
- Deliver stronger long-term benefits for the UK’s economic growth
Adlington, as a smaller and more rural location, was not considered to offer the same level of impact.
2. GREENFIELD DEVELOPMENT CONCERNS
The proposed development area around Adlington is mainly undeveloped countryside (greenfield land).
This means the development would:
- Lead to a permanent loss of open countryside and agricultural land
- Change the character of the local landscape significantly
- Require significant groundwork and infrastructure from scratch
In contrast, some other locations focused on redeveloping Brownfield sites, which are generally preferred as they reuse existing land and reduce environmental impact.
3. TRANSPORT AND CONNECTIVITY CHALLENGES
Transport links were identified as a key weakness.
Although Adlington does have a small train station, the report notes:
- Train services are relatively infrequent
- The area is not well connected to wider public transport networks
- Bus services are limited
To support a large new town, major investment in transport infrastructure would be needed. This adds significant cost and complexity, and makes the location less attractive compared to areas that are already well connected.
4. FLOOD RISK AND DRAINAGE ISSUES
The report highlights concerns around water management.
Building a large number of homes would:
- Increase hard surfaces such as roads and roofs
- Lead to more surface water runoff increasing flood risk locally
- Put pressure on existing drainage systems
This creates a risk of increased flooding both on-site and in surrounding areas. While these issues can be managed with modern design, they are still considered a negative factor in the assessment.
5. ENVIRONMENTAL AND CONSTRUCTION IMPACTS
Building a new town of this size (up to 20,000 homes) would inevitably have short- to medium-term impacts during construction, including:
- Noise, dust, and disruption during construction phases
- Increased traffic and air pollution from construction vehicles
- Pressure on nearby communities and services
These effects are common with large developments but still count against the site. There could also be longer-term environmental impacts, such as changes to air quality and increased traffic levels once the town is built.
6. NO STRONG ADVANTAGE OVER OTHER LOCATIONS
Adlington was not ruled out because it performed badly overall.
Instead, the issue was that:
- It had similar challenges to other sites (environmental impact, infrastructure needs)
- But did not offer strong enough advantages to outweigh those challenges
Other locations were able to demonstrate clearer benefits—particularly in terms of economic growth, regeneration, and existing infrastructure.
FINAL SUMMARY
Adlington may be a practical and deliverable site with development potential, but it was not selected because it does not deliver the level of economic benefit or strategic importance seen in other proposed locations, particularly larger urban areas.
When this is combined with the clear environmental impacts, infrastructure challenges, and the loss of valuable greenfield land, it reinforces what many have said from the beginning. ADLINGTON IS NOT A SUITABLE LOCATION FOR A DEVELOPMENT OF THIS SCALE.
Importantly, this outcome also reflects the strength of local opposition. Residents, community groups, and both Cheshire East, and Town & Parish councils have made their concerns clear, demonstrating a strong and united voice against the proposal.
This decision shows that those concerns have been heard. However, it also underlines the importance for us to continuing to stand together and remaining vigilant.
We must continue to protect our local area, our countryside, and our community from inappropriate large-scale development.
