GREEN STREETS O&M
BEFORE AFTER
Maintenance Activities for Bioretention Area
Activity Schedule
 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.
First Season
 Prune and weed to maintain appearance.
 Mulch replacement when erosion is evident.
 Remove trash and debris.
As needed
 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.
Semi-annually
 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.
Annually
 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)
2 to 3 years

Profile Form and submit
to contracted waste
hauling company to
classify as non-
hazardous.

60. CONTROLS TO REDUCE DEICING
POLLUTANTS
 Alternative Deicing Materials
(Beet Juice “Eco Friendly Deicer”)
 Known commercially as GEOMELT, the
beet juice is made from the carbohydrate
extract of sugar beets, and when mixed
for use on roads can reduce the amount
of salt needed by 30%
 Salt Spreader Calibration
 Covering Stored Equipment
 Salt Barn
 Loading/Unloading Procedures
 Annual Snow Fighter Training
 Snow Plow Routes (post in facility)
 Keep “Maintenance Log Binders” (keep in
plow truck)
 Proper snow disposal areas

61.  Minimize use of fertilizers
 Consider no-mow zones
 Direct mowers away from
street to minimize grass in
the streets and catch basins.
 Consider native vegetation
and low maintenance trees
 Properly maintain trees
(natural target pruning)

62.  Ensure public works are properly
pruning trees = “natural target pruning”
 Proper cuts are made at a branching
node (where one branch is attached to
another) just outside the branch collar
 Be sure to cut branch tissue and not
stem tissue.
 Better to cut too far than risk making a
flush cut.
ENSURE PROPER PRUNING

63. CONSIDER LOW MAINTENANCE
 Hazard potential - avoid planting
brittle species that are prone to
breakage during storms/ high winds
 Ex: Silver Maple, Siberian Elm,
Weeping Willow….
 Small leaves/leaflets - reduces
clogging of sewer drains
 Ex: Honey Locust, Cypress...
 Cultivars - developed for desired
features like resistance to pest &
disease, leaf/flower color, form,
size, lack of fruits…

64. RIPARIAN ZONE PLANTING – IDNR
GRANT
