Aircraft safety – developments in the proximity of airports - KBCN0912

Where it can be demonstrated that an assessed development, within or adjacent to an airport or similar, must restrict the ecological value of the site for reasons of aircraft safety (mitigating the risk of bird-strikes to meet local or national regulations), the approach for some issues in the Land Use and Ecology category can be adjusted. If in these circumstances, the client wishes to enhance ecological value on an external site, outside of the main development site, this can be considered in the following way for each issue: Site selection: The development site only must be assessed. Ecological value of site and protection of ecological features: The development site only must be assessed, but the recommendations may be tailored to suit the requirements of the relevant legislation. Enhancing site ecology: The development site and the external site must be included in the SQE’s report and recommendations, albeit that, for the development site, the approach may to be to restrict biodiversity. Enhancements implemented in-line with the recommendations of the SQE are likely to apply to the external site. Long term impact on biodiversity: Both sites must be considered in the SQE’s report to meet the prerequisite/first credit as applicable, albeit that, for the development site, the approach may to be to restrict biodiversity. Further credits in relation to improving and maintaining the site’s long-term biodiversity can be awarded on the basis of adopting these for the external site only, in line with the guidance.

Contaminated Land- Presence of radon gas - KBCN0155

Naturally occurring radon is not considered as contamination in relation to BREEAM. However, where radioactive substances have been introduced as a consequence of human activities, that land would then be considered to be ‘contaminated with radioactivity’ and remediation of such contamination would fall under the scope of the relevant BREEAM issue.

Land reclaimed from the sea - KBCN0558

Land reclaimed from the sea cannot be considered as previously developed land. It has not been occupied by a permanent structure and any associated fixed surface infrastructure (please refer to the Additional information section).

Previously developed land – temporary structures - KBCN0659

The presence of concrete and hardstanding areas established as temporary structures for enabling works are not considered to be previously developed land on a site. The nature of enabling works are temporary; with the purpose of enabling the delivery of a development and are not constructed to be permanent. Temporary structures of this kind are not included in the definition of previously developed land no matter how long they have been present on a site.

Previously occupied land – Fixed surface infrastructure - KBCN1140

Car parks and other hard-landscaped areas often incorporate small pockets of soft landscaping. Where these are integral to the hard landscaping and constitute a small proportion of the total area, these areas can be considered as part of the fixed surface infrastructure.

Sites with multiple assessed buildings - KBCN0920

For sites with multiple assessed buildings, where it proves difficult to clearly define separate construction zones for each building, the assessment of this Issue can be done on a site-wide basis where the boundary of the construction zone is considered to be the whole site. Similarly, when it is difficult to define the proposed development footprint for each assessment, the issue can be assessed on a site-wide basis. This can be applied to each BREEAM assessment.

Unexploded ordnance - KBCN0775

Unexploded ordnance can be defined as a contaminant as they are objects which can be classed as a hazard to health and/or the environment.  Therefore, if the contaminated land specialist confirms that leaving the ordinance on the site would lead to a serious risk to human health and the environment, the site can be defined as “contaminated land” (please see the definition within the 'additional information' section of the manual). However, the credit can only be awarded where all criteria have been met, and therefore the site investigation, risk assessment and appraisal must determine that the site is “significantly contaminated” i.e. without remediation, development of the site is not possible. Also, it should be noted that decontamination needs to occur specifically for the purpose of re-development of the site, as detailed in the compliance notes “Prior Decontamination” and “Health and Safety related decontamination.”
