==Selection of suite of LIDs: the Treatment Train Tool==
[[File:LIDTTT.png|thumb|LID Treatment Train Tool]]
In order to assess if the selected suite of BMPs effectively meet the design criteria, use either computer models or simple spreadsheet models. Base Mmdel selection on the size and type of development. A wide range of simple to complex computer models such as Visual OTTHYMO, SWMM, SWMMHYNO, HSP-F and QUALHYMO are available.
STEP have developed the [http://www.sustainabletechnologies.ca/wp/low-impact-development-treatment-train-tool/ Low Impact Development Treatment Train Tool] to help developers, consultants, municipalities and landowners understand and implement sustainable stormwater management planning and design practices.

After selecting a suite of BMPs and running the models, make a comparison between the modelling results results and the environmental design criteria. Employ nn iterative approach, which involves adjusting the size or adding/deleting BMPs until the environmental design criteria are met. The [http://www.sustainabletechnologies.ca/wp/low-impact-development-treatment-train-tool/ LID Treatment Train Tool] can help with adjusting the size of the features to meet design criteria. Once met, the project can proceed to the detailed design stage.
