Brownfield Regeneration & Landfill Transformation
As development has progressed in Ireland’s major population centres, project planners look more and more to recycle and repurpose previously used land.
This ‘brownfield’ redevelopment is actively encouraged by government and has a lot of potential to do good by cleaning up dilapidated and abandoned industrial and commercial developments, like:
- Former Factories
- Processing Mills
- Landfill Sites
- Chemical Refineries
- Railway Yards
- Military Bases
- Commercial Estates
Disused factories and industrial parks are some of the most dismal aspects of the urban landscape, symbolising poverty and decline to economically deprived areas. When private investment capital is put to repairing and rebuilding these areas, it can help to solve social, environmental and economic problems.
Before construction can start though, these types of sites often need work to clean up pollution by toxic substances:
- Heavy metals e.g. arsenics, cadmium and lead
- Oils and tars
- Chemical substances and preparations e.g. solvents
- Radioactive substances
The Triple-Bottom Line - Economic, Social & Environmental Wins
When developers, local authorities and national agencies work together to regenerate brownfield sites, amazing transformations are possible - with positive knock-on effects to local residents, and the environment:
Landowners and developers work with the EPA to clean up the contaminated lands before construction begins, improving the site for all local residents.
Head contractors hire local subcontractors to carry out site works, and their on-site teams spend money at local shops and cafes daily for the duration of the project.
The new developments attract established business owners to the area.
Vibrant local economies attract new residents to the area, creating demand for further housing and amenities like schools and sports facilities.
Taken together, all of this activity is creating new jobs, building businesses and making Ireland an ever-better place to live and do business.
The Special Case Of Historic Landfills
Landfills are different from other types of contaminated sites. The polluting material was placed in the ground purposefully to dispose of human domestic waste, and it’s usually not practical or desirable to remove it.
So development plans for landfills are created around compaction and sealing of the waste material with high durability membranes, then capping over the sealed waste with soils and planting the site.
Provision is also made for the venting of methane and other gases which are produced by the waste materials sealed underground.
Former landfills are usually not suitable for built physical infrastructure because of land stability, but they are ideal for transformation into public parks. This has been done with great success around the world for over 100 years, and can be seen here in Ireland at the Waterford Nature Park - Kilbarry and the Tramore Valley Park in Cork
Compliance, Regulation & Risk Management
Government guidance recognises land contamination as a material planning consideration.
From a practical perspective - the preliminary groundworks phase of a new development
is the most cost-effective time to deal with the problem of contamination.
And from the liability risk management approach, it’s the developer’s responsibility to ensure that the development is safe,
suitable for its intended use, and compliant with both local and EU regulations.
The European Communities (Environmental Liability) Regulations 2008, came into force in Ireland on 1 April 2009 -
https://www.epa.ie/enforcement/liab/. These Regulations created a framework of environmental liability
to prevent and remedy environmental damage.
Ireland’s Environmental Protection Agency - https://epa.ie - is the national goverment-appointed authority
to implement these and other environmental laws and regulations.
In 2013, the EPA published a guide to the management of contaminated land, laying out a 3-stage process to redevelop brownfield sites as shown to the right.
Like all engineering processes, Stage 1 begins with investigating the situation and assessment of findings before a plan is drawn up.
That means exploring what’s on, in and under the soil, and mapping the site to identify risk areas, before samples are extracted and the digging works begin.
