Therefore therating reduces to Moderate.The table below provides a summary of the impact on soils and land capability in theconstruction phase.Table 22: Impact Rating Matrix for soils and land capability during the constructionphase (Alternative 1-3).Type of Significance Spatial Temporal Probability RatingImpactInitial VERY HIGH Study site Long Term Is Occurring 3.7- HighAdditional HIGH Study site Short Term Will occur 2.7- ModerateCumulative HIGH Study site Long Term Will occur 3.3- HighResidual HIGH Study site Long Term Very Likely 2.7- Moderate11.1.2 TopographyInitial ImpactThe study site is within the existing fenced off existing waste disposal site; therefore thetopography of the study area is already disturbed.
