2 For the consolidated constraint of a given lot to be assigned a high constraint class, there needs to be at least one high discrete constraint and the rest all moderate constraints or varying combination with more than one high constraint or the depth to groundwater is ‘non-compliant’ which will increase a moderate constraint to a high constraint.
High = 13 - 18 Moderate = 7 - 12 Low = 6
