When Enviro-Girl lived in town, she marveled at the gigantic snow blowers her neighbors employed to clear 20-40 feet of sidewalk and a short driveway to the street. Enviro Girl’s garage was set back from the road and she shoveled three times the area her neighbors blew out with snow blowers. Shoveling is a heck of a work out, inducing sweat and heavy breathing within minutes –- but it’s the friendliest way to clear the snow. The trick to making shoveling a reasonable task is using the correct tool –- a shovel appropriate for your build and height – and attacking the snow in manageable bits. If 6-8 inches are expected to fall, shovel two to three times during the snowstorm so you’re only clearing a few inches at a time. If you can’t do this, only clear what’s necessary in the first round and clear the rest later. A 2-foot wide path is adequate for mail carriers and pedestrians, and you might consider only clearing a path to one entrance of your house and leave the other access points alone. If you get less than 2 inches of snow, you can clear it away using a broom.
Shovels produce no emissions, exhaust, air or water pollution–the person using the shovel might feel exhaust, but Enviro Girl argues most of us would benefit from the exertion of shoveling snow. Shoveling snow won’t annoy your neighbors because it’s pretty quiet and it’s cost-effective. You can purchase a snow shovel for $10-30 and they cost nothing to maintain or operate.
If you’re inclined to remove snow using industrial-strength machinery like Enviro-Girl’s husband, remember that bigger isn’t always better. A plow attached to an ATV uses less fuel and makes less noise than his 6.5 hp snow blowing machine. (Enviro-Girl thinks her hubby is overcompensating every time he buys equipment with engines…you should see his chainsaw.) An electric snowblower (Toro makes one that runs about $299) uses less energy, makes less noise, and gives off no emissions in stark contrast to its gas-powered counterparts – so if you must blow snow, electric is definitely the way to go.
But snow’s only part of the problem in the winter. Ice simply must be dealt with and there are various methods to employ. You can chip it away, potentially damaging the concrete/asphalt beneath. You can scatter other substances on top of the ice to gain traction on the ice until it melts naturally – sand, cat litter, bird seed, and fertilizer are good choices. These things won’t melt your ice, but they’ll help you travel over it safely until sunshine and warmer temperatures do make the ice disappear. (Enviro-Girl is going to try used coffee grounds next time her driveway freezes over. It’s important to note that she has a strict rule about no shoes or boots in the house!)
If you can’t wait for Mother Nature to take care of things, you can melt the ice. Some places install heated walkways and driveways – radiant heat systems that run hot water pipes below the brick or concrete. These use a lot of energy. Rock salt melts ice and is fairly inexpensive, but it’s really tough on plant life and when it drains away through storm sewers it can mess up ecosystems in lakes and rivers. Too much chloride is toxic to freshwater plants and animals. It runs off into water supplies, it kills roadside plants, it builds up in streams and lakes, it can degrade the soil. It’s also rough on cars, skin, and road surfaces. Rock salt doesn’t work at temperatures below 20 degrees Fahrenheit, either. In response to the rising costs of road maintenance and environmental concerns, many municipalities have switched to applying brine–rock salt and water combined–before ice can form. Brine saves money and leaves behind less salt residue. Sugar beet juice mixed with brine is being studied in several communities because it works well at temperatures as low as -30 degrees Fahrenheit and reduces the amount salt required to melt ice. Many people use Calcium Chloride for melting ice. It’s three times as costly as rock salt and can still cause skin irritation, but very little Calcium Chloride goes a long way in melting ice. Calcium Chloride poses the same environmental risks as rock salt.
At the end of all her research, Enviro-Girl plans to use traction on the ice in her driveway. She’ll chip away at it with her handy chipping tool (a great work out!) and pray for warmer temps soon. One other thing Enviro-Girl has learned: if you let an ice storm fall on a cleared driveway, you’ll have a skating rink that is impossible to clear. If you let an ice storm fall on a snow-covered driveway, you can shovel the ice and snow off pretty easily. In this case, a little laziness paid off on half of her driveway – unfortunately it isn’t the half she needs to drive on!
Disclosure: Enviro Girl and her family didn’t clear their rural 1/4 mile driveway with a snow shovel — they depend upon a neighbor with a tractor.
