Water from rainfall and spray park flows over land to concrete flow channels and into rain gardens, where water soaks into soil and pollutants are filtered out. Any overflow moves through flow channel on to the next garden, with final discharge at storm sewer.
Regular inspection and maintenance are critical to ensure that rain gardens function as designed and should be performed per the schedule below as part of routine park maintenance operations:
Maintenance & Inspection Activities
For first 3 years rain gardens and trees must receive weekly watering. Encourage public to use spray-park during unseasonably hot and dry periods.
Mow and weed-whack turf around the gardens and direct clippings away from the infiltration beds
Remove trash and organic debris from within and around gardens
All inspections/activities are intended to be performed during the growing season, and on an as-needed basis
Sediment shall be disposed of offsite in a pre-approved location
TROUBLESHOOTING AND LONGTERM MAINTENANCE
Some maintenance and inspection considerations are beyond the basics and may require some troubleshooting
