Click on Run and you will see a Blue progress bar at the bottom of the screen and at the end of the Run an Info Dialog Message Box. The Optimizer runs many InfoSWMM runs to optimize the selected LID Types. The Number LID Candidates should be two now and the ID's should be 173 for Subcatchment 2 and ID 199 for Subcatchment 1. Sort the LID Type Rows by Unit Area and then using the delete Row Icon delete all except the 1st Two Rows STEP 13: The Reduced Number of LID Candidates

STEP 12: Reduce the Number of LID Types for this Introductory Tutorial Use the BlockEdit tool again and set the Percent Imperviousness Area Treated to 5 percent per LID Type. STEP 11: Moodify the Percent Imperviousness Area TreatedР”Р„n important rule is that the total area treated by all LID Types for a particular Subcatchment does not exceed 100 percent of the impervious area. The parameters are for type of Optimization Technique, the Cost Improvement Threshold, the Maximum Number of Iterations per Model Run, the Maximum InfoSWMM Model runs and the Number of Best Solutions to be Found during the Optimization Process. STEP 10: Click on the General Tab to Define the Optimizer Parameters We will use the preset targets of 80 percent for Runoff and Water Quality for all of the Subcatchments. STEP 9: View the Optimization Targets for Runoff and Water Quality Use the BlockEdit Tool or Icon to set the LID Control for all of the other Rows with an LID Type of Green Roof. STEP 8: Set the LID Control for all Rows of the LID Candidate Rows

Click on the LID Control Box and Select a LID Control. It is possible to have more than one LID Control (from the Operations Tab of the InfoSWMM Browser) for all of the Green Roofs. You have to decide the actual LID Control for each LID Type. STEP 7: Import all of the LID Candidates found by the Siting Manager of InfoSWMM SustainР”Р„ll of the possible Green Roofs on Subcatchments 1, 2 and 3 are now found. Use the LID Optimizer tool (1) to import all of the LID's with a Subcatchment (2). The Siting Manager will find Green Roofs for the whole watershed but we will only use the LID Types on a Subcatchment.

STEP 5: Open the LID Types Atrribute Table to see the Green Roof Possible Locations The InfoSWMM Message Board Window will show creation notes and whether there were any errors in the creation of the Green Roofs. STEP 4: Click on Process to Find the Possible Sites for the Green Roofs Use only the Criteria for Building Buffer and Percent Imperviousness as shown below: STEP 3: Define the LID Siting Criteria for Green Roofs You add one LID Type and define the Siting Criteria one LID Type at a time. Use the Siting Manager and Click on the Add LID Types STEP 1: Use the Siting Manager to Choose Green Roofs The folder will have the Arc Map MXD file, the DB folder and the GIS Data needed for Tutorial 1. The GIS data and the Sample Sustain Model will be found in your InfoSWMM Examples folder This tutorial assumes you have already added your GIS data to the example model of InfoSWMM Sustain. As such, it should be used as a launching point to a more comprehensive understanding of the program. Tutorial 1 is designed for first-time users of InfoSWMM Sustain and provides a guided tour to core commands and functions used to create and execute a Siting and Optimization run in InfoSWMM Sustain. In Tutorial 1 we will use the Siting Manager to Site Green Roof LID Types for later Optimization and Export to the InfoSWMM LID Usage DB Table.
