Guidance

Technical Clarification

Miscellaneous topsoil

Technical Clarification Number
ECO1-T-OB1-0106

Guidance
2010-10-13

Topsoil contained within non-permanent landscape, such as potted plants, planter boxes, or other non-insitu landscape features, which can be removed or relocated, is not considered part of the ‘site’ and is therefore not within the scope of the Eco-1 Topsoil credit. All other topsoil, including that contained in permanent or insitu landscape features, must be included in calculations demonstrating compliance with the credit criteria.

 

Technical Clarification

Contaminated soil

Technical Clarification Number
ECO1-T-OB1-0010

Guidance
2009-02-06

Pre-exisitng contaminated topsoil is excluded from this credit and is dealt with in the following two ways.
1. For contamination of a portion of the existing topsoil, the contaminated soil is not included in the topsoil calculations.
2. For contamination of all existing topsoil, the credit is 'Not Applicable' and should be marked 'na' in the appropriate 'No. of Points Achieved' column of the rating tool.

If existing topsoil is contaminated during the construction process, the credit can not be earned and must be marked as zero points achieved.

 

Technical Clarification

Reused topsoil

Technical Clarification Number
ECO1-T-OB1-0002

Guidance
2009-02-05

Topsoil that is reused on other building sites does not qualify for credit. The productivity and value of topsoil is linked to the site it is located on, and moving topsoil between building sites may compromise its ecological integrity. In order to achieve the credit, project teams must demonstrate that 75% of all protected topsoil remains productive and on site.
