Park Nicollets Award winning snow and ice program What does it take - PowerPoint PPT Presentation

Park Nicollet A WIN/WIN Park Nicollet’s Award winning snow and ice program

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 De-Icing Pre-WeNng Treatment • Is the process of spraying • Post applica(on of a granular • A liquid treatment to the salt aKer a plow event. It granular salt with a pavement prior to a snow ice takes longer for granular salt event. Prevents bonding of solu(on of brine or brine/ to become a solu(on and snow and ice to the calcium liquid as a post melt ice and or snow. pavement. Reduces overall applica(on. salt usage. Reduces damage to landscape. Can be effec(ve up to 4-5 days prior to a snow event 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. 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 (NOTE: THESE ARE PAVEMENT TEMPERATURES)

SPRAY JUGS AT EACH ENTRANCE

An(-Iced/Pre-treated drive lanes aKer a snow event. CLEARLY OUTSTANDING RESULTS!

Sidewalks being pre-treated before an ice event. This saves on labor costs, material costs and reduces threat to the environment. All without compromising safety.

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.

Site Maps and Snow Storage

Park Nicollet ‐ Maple Grove Specialty Center 9555 Upland Lane N.,, Maple Grove PNMGSC Account Manager – David Eddy Detailed Site Maps for each property Heated walk in Orange Temporary Snow Storage in Green Blow Back areas in Blue Handicap stalls in pink and white Crosswalks in Pink 1” Plow trigger .1” Shovel Trigger Business Hours: M ‐ F 8:00 am to 8:00 pm, Saturday 8:00 am to 5:00 pm Snow and Ice Management Details: 1. 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.
