Keep grass clippings out of the street.
Vegetation Management O&M After:
GREEN STREETS O&M
Maintenance Activities for Bioretention Area
Supplement normal rainfall (at least 1”/week).
Replace plants as needed.
Inspect all plants to assess additional needs.
Inspect site for proper drainage after each 2” or more rain event.
Mow non-woody perennial plant dead stalks/dieback in the spring.
Prune and weed to maintain appearance.
Mulch replacement when erosion is evident.
Remove trash and debris.
Inspect inflow points for clogging (off-line systems). Remove any sediment.
Inspect filter strip/grass channel for erosion or gullying. Re-seed or sod as necessary.
Trees and shrubs should be inspected to evaluate their health and remove any dead or severely diseased vegetation.
Inspect and remove any sediment and debris build-up.
Inspect inflow points and bioretention surface for build-up of road sand associated with spring melt period. Remove as
necessary and replant areas that have been impacted by sand/salt build up.
Mow non-woody perennial plant dead stalks/dieback in the spring.
Replace mulch over the entire area.
The planting soils should be tested for pH to establish acidic levels. If the pH is below 5.2, limestone should be applied.
If the pH is above 7.0 to 8.0, then iron sulfate plus sulfur can be added to reduce the pH. (slow release fertilizer)
