Site assessment and remediation is the way to go – But how much will it cost?
Guidance on dereliction, demolition and remediation costs
An updated version of the Guidance on dereliction, demolition and remediation costs (March 2015) has been published and is available to download by clicking here.
The document outlines that brownfield land has an important role in delivering housing and supporting economic growth. Given the potential that brownfield land holds it is important that brownfield development occurs and central and local Government (and their agencies), developers and landowners work together to overcome potential obstacles to delivery.
It has been prepared by the Homes and Communities Agency (HCA) which is the national housing and regeneration agency for England who contribute to economic growth by helping communities realise their aspirations for prosperity and delivering high quality housing that people can afford.
Site investigation – bespoke and fit for purpose, overcome potential obstacles to delivery.
Estimating the cost of preparing a brownfield site for reuse can be a complex exercise and one that has uncertainties. Due to high levels of potential risk and associated uncertainty nothing competes with a recent and well executed site investigation that has been designed with full regard for the land use history and the new proposed development.
2005 Guidance Updated
The HCA initially developed a guide in 2005 to assist project managers and development partners form, at an early stage, an opinion as to the costs of the remediation of the contamination and demolition of buildings. These estimates could then be included in a project appraisal, possibly even prior to the appointment of consultants and the provision of site-specific advice. The 2005 document has been revised and presents an update on cost estimates for the remediation of land affected by contamination based on 2014 prices. There is even regional weighting to account for cost differences across the UK.
All you need is a well executed site investigation that has been designed with full regard for the land use history and the new proposed development… But how often does this occur?
The revised edition of the guide includes additional guidance on pre-acquisition site investigations, as part of ‘due diligence’ and expands the remediation costs to include problems associated with demolition.
Contamination is typically dealt with when a site is developed and it is the developer’s responsibility to provide a new development that is suitable for use.
Risk Based Approach
In GP3 the Environment Agency state they support a proportionate, risk-based approach, but may object if they judge the risk of water pollution is too high or not properly assessed. This is where H2Ogeo can assist with extensive regulatory experience in assessing the risk to controlled waters throughout the UK and overseas.
Speak to H2Ogeo about risk assessment and brownfield development
The level and nature of the risk will be dependent on the proposed use of the land and the sensitivity of the environment. So, if you have a site that needs assessment or you need advice on the requirements associated with brownfield development contact H2Ogeo to find out more.
