After determining the potential flood impact, use the Editing toolbar to create levees. Several feature templates have been developed for the Levee layer.

The Attribute Assistant Add-In automates attribute population and calculates the cost estimate for levee materials. As the levee attributes (height, width, slope, and so on) are entered, the Attribute Assistant Add-In computes the number of cubic yards of material needed and a cost estimate for the levee.

To estimate the cost of levee construction, complete the following steps:

1. Browse to the MapsandGeodatabase folder and open FloodPlanning.mxd.
2. Start an edit session.
3. Click the Create Features button and click the levee type you want to create.
4. Use the Line construction tool to draw the levee on the map.
5. Fill in the feature attribute for the new levee by typing the levee dimensions in the appropriate fields. As the levee attributes are populated, the Attribute Assistant Add-In calculates the cost estimate for levee materials.
