Agenda OVERALL MESSAGE: How to create more effective facilities (ones that protect your watershed) that are less costly and lower maintenance! Top 10 Common Mistakes to Avoid: Considerations for planning, design, construction & maintenance of common bioretention components
1. Suitable Infiltration Areas are NOT found on a NRCS soils map
You must test your soil where bioretention is going to be located
2. Flow-Through (Lined) Facilities are NOT nearly as good as infiltration facilties 43 Lined on three sides with an impermeable liner = “Flow- Through”
Detention Basin & Flow Through Facilities Results from a Watershed Perspective
8. Protect Against Erosion Rounded Rock Doesn’t Adequately Slow Water Use crushed, angular rock instead
8. Protect Against Erosion Don’t plant vegetation in rows parallel to flows
8. Protect Against Erosion but don’t use the dry creek bed look To maximize water quality treatment, plants must be in the bottom, where the most polluted “water quality” storm flows the most often.
