Park Nicollet’s Award winning snow and ice program

Park Nicollet

A WIN/WIN

What does it take to be prepared for snow?

• Calibra(on of equipment
• Equipment maintenance
• Training for operators and employees.

What makes a good contractor?

• SIMA best prac(ces
• CSP cer(fica(ons
• ASM cer(fica(ons.

DEFINITIONS OF TERMS

An( Icing/Pre Treatment

• A liquid treatment to the

pavement prior to a snow ice

• event. Prevents bonding of

snow and ice to the

• pavement. Reduces overall

salt usage. Reduces damage to landscape. Can be effec(ve up to 4-5 days prior to a snow event

De-Icing

• Post applica(on of a granular

salt aKer a plow event. It takes longer for granular salt to become a solu(on and melt ice and or snow.

Pre-WeNng

• Is the process of spraying

granular salt with a solu(on of brine or brine/ calcium liquid as a post applica(on.

Wet salt adheres to the road instead of bouncing off of the road into the landscape. Therefore, less salt is applied.

To be effec(ve as a de-icing agent salt requires moisture. Moisture dissolves the granular salt, releasing heat and thereby mel(ng ice and snow as well and breaking the ice road bond. When temperatures drop below zero, there is generally liQle or no moisture in the pavement. Pre-weNng insures that there will be sufficient moisture to ac(vate the mel(ng process.

Pre-TreaAng

• CUSTOMIZED EACH APPLICATION AND BLEND TO EACH EVENT AND THE EVENTS
• CONDITONS. PRE TREATING WITH LIQUID BRINE IS ESSENTIAL. THIS INCLUDES:

ROADWAYS, DRIVES, PARKING LOTS, RAMPS, BRIDGES SIDEWALKS AND PARKING DECKS. (NOTE: THESE ARE PAVEMENT TEMPERATURES)

15 F 23.3% BRINE

14 F – 5 F

23.3% BRINE AND 20% CALCIUM 4 F – -20 F 23.3% BRINE AND 30% CALCIUM

HOW WE HAVE ACCOMPLISHED SALT REDUCTION

• GREATER USE OF LIQUIDS, ANTI ICING
• TIMING OF LIQUID APPLICATIONS
• USE OF LIQUIDS, PRE-WETTING WITH GRANULAR SALT
• CALIBRATION OF CONTRACTORS EQUIPMENT
• UPGRADING CONTRACTORS EQUIPMENT
• GREATER USE OF ROTARY BROOMS ON SIDEWALKS
• USE OF 25 POUND SALT BAGS VS. 50 POUND BAGS
• LIQUID CONTAINERS AT THE ENTRANCES
• PERSISTANT ICE CHECKS THROUGHOUT WINTER
• DEFINDED PARAMETERS FOR WINTER WITH USE OF SITE MAPS.
• NO COMPROMISE TO SAFETY.

LANDSCAPE REDUCTION COSTS

• 2013 Park Nicollet/Methodist Landscape repair costs totaled near:

$150,000.00

• With the use of liquids, training, calibra(on, 25# bags of salt.
• 2017 Landscape repair costs: $28,000.00

Refer to the snow storage map for locations to store snow. 2. Refer to the snow and ice management guidelines. 3. This is a very busy property. The north side of the building and the drop off area can become slippery quite quickly. 4. The east side is under construction. This area is also prone to snow blowing off the roof. 5. Do not use granular ice melt on the heated sidewalks by the front doors. 6. If any parking stalls are used for snow storage, we are to automatically come back within 24 hours to relocate. 7. Treat all crosswalks as if they were sidewalks. 8. Drive lanes and sidewalks must be kept clear during business hours. No exceptions. 9. Do not cause damage to fences, gates or signs.
