MAINTENANCE RECORDS

Merrillville has 6063 inlets and

804,713 feet of storm drains that

are routinely cleaned with our Jet

Vac and viewed with the camera

truck to assess condition. Video

footage is saved for our records.

Information is utilized to identify and

prioritize routine maintenance

projects

INFRASTRUCTURE MAINTENANCE

After market pipe nozzles can

be 30-50% more efficient than

conventional sewer nozzles.

Removes more debris and

saves time so more drains can

be cleaned.

IMPROVING INFRASTRUCTURE MAINTENANCE

INLET PROTECTION PROJECT FOR MUNICIPAL

FACILITIES & STREETS Permanent inlet treatment devices are

becoming more common for

hydrocarbon filtration.

Requires maintenance, monitoring

and replacement.

Also have vortec separators for new

municipal roadway projects.

sustainability of roadways.

Many are roadway redesign with

adjacent rain gardens.

Public works maintenance will be vastly

different.

construction conditions

GREEN STREETS PROJECTS

BEFORE AFTER

Vegetation Management O&M Before:

Mow area weekly.

Keep grass clippings out of the street.

Vegetation Management O&M After:

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

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

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)

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

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…

RIPARIAN ZONE PLANTING – IDNR

GRANT

Survey areas that need

armoring or reconstruction.

Look at alternative green

streets design to change the

profile and cross-section of

the ditch and/or roadway.

Show examples of these

projects during audit.
