Click to download the METRIC model files.


  1. Continue with your previous file or open XP_Tutorial1.xpdx.

  2. Select the Developed Phase from the drop-down list in the Tree View panel. The background image will be updated and display the proposed property boundaries and building footprints.



  3. Before you plan the Developed site design, you can apply a Deluge to the site in order to identify main flow paths and ponding areas based on the Surface that has been loaded.  To use the Deluge quick overland flow analysis, right-click the Deluge layer and select Go, as shown below:


  4. Accept the default analysis parameters and then click OK.


    A surface flow depth map with hazard (velocity*depth) vector arrows will be shown.


  5. The Deluge map provides information on runoff within the site and can be used as a guide for laying out stormwater control systems and other site features. For example, swales can be located along natural flow paths, and buildings located away from ponding locations. The Deluge map is showing that runoff will naturally collect in the middle of the site and then drain to the north-most boundary. We will plan the placement of our Stormwater Controls in these areas to minimize site grading. 

  6. Turn off the visibility of the Deluge map by clicking the Deluge layer check box in the Tree View panel.


  7. Save the file as XP_Tutorial2.
