Pre-treatment structures are most cost effective when they slow down incoming flows, collect sediment for easy clean out, and release water to the bioretention facility in a non-erosive way. <br>

Some pre-treatment structures/strategies include:
* Vegetation: If sized correctly, it works more effectively in areas with more dispersed flow. However, in concentrated flow and sediment areas it might not be the best option. Sediment removal can be more difficult in areas of dense vegetation. An advantage of using vegetation as pre-treatment is that it can be easily integrated into the landscape design.
