Towards a Minerals Local Plan for Derbyshire and Derby

Sand and Gravel Site Assessments

Analysis of Results

Analysis of Results

The scores for all the criteria for the social and economic categories have been added to produce a total for each category, as set out in the assessments above. For the environmental criteria, the scoring from the environmental matrix in Appendix 1 below has been used. This combines both the site assessment work (set out above) and the strategic environmental sensitivity work (set out in a separate paper).

For each category, the sites were then ranked, so the lowest scoring site achieves a ranking of '1' (i.e. low potential for mineral working). Where two sites scored the same, the difference was split (so for example if two sites had an economic score of 17, and would have been ranked 2nd and 3rd, they have been assigned a ranking of 2.5). Where three sites got the same score, all sites were allocated the middle ranking, for example, if three sites scored the same and are 4, 5 and 6 in the ranking order, they have all been assigned the middle ranking of 5.

The economic, social, and environmental rankings were then added together to provide an overall score - theoretical maximum 24, minimum 3. This has determined the overall potential for working each site. Sites with high potential are deemed as potential allocations in this Minerals Plan. Sites in the medium category may have the potential to be considered as allocations if there are insufficient sites in the "High" category to meet the remaining requirement, or if during the Plan period, monitoring indicates that the allocated sites are not being, or will not be, delivered as anticipated. Sites with low potential will not be considered for allocation in the plan, and are likely to be protected from mineral extraction.
