This guidance article intends to help reduce the number of LID options in the preliminary phases of design and to alert the designer to LID opportunities unique to the site-type being assessed. When going through the process of screening LID options, it is important to have a larger contextual understanding of [[Integrated water management]], [[Site design strategies]], and [[Siting and layout of development]].

After selecting a suite of BMPs and running the models, make a comparison between the modelling results results and the environmental design criteria. Employ an iterative approach, which involves adjusting the size or adding/deleting BMPs until the environmental design criteria are met. The LIDTTT can help with adjusting the size of the features to meet design criteria. Once met, the project can proceed to the detailed design stage.
