It includes both mechanical means, such as plowing, vacuuming or scraping, and chemical means, such as application of salt or other ice-melting chemicals. Anti-icing is treatment with ice-melting chemicals before or during the onset of a storm in order to prevent or delay the formation and adhesion of ice and snow to the surface. <a href="/wiki/Brine" title="Brine">Brine</a>, or wetted salt, is usually applied shortly before the beginning of a snowstorm. When properly performed, anti-icing can significantly reduce the amount of salt required and allow easier removal by mechanical methods, including plowing.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The de-icing of roads has historically been accomplished by <a href="/wiki/Snowplow" title="Snowplow">snowplows</a> or specially designed <a href="/wiki/Dump_truck" title="Dump truck">dump trucks</a> that spread <a href="/wiki/Salt" title="Salt">salt</a>, often mixed with <a href="/wiki/Sand" title="Sand">sand</a> and <a href="/wiki/Gravel" title="Gravel">gravel</a>, onto slick roads. <a href="/wiki/Rock_salt" class="mw-redirect" title="Rock salt">Rock salt</a> is normally used because it is inexpensive and readily available in large quantities.

Owners of large buildings or building complexes generally have mechanized snow-removal equipment, but individual house owners mostly clean the sidewalk with hand tools. </p><p>One example of the longstanding debate over the obligation of snow removal comes from the <a href="/wiki/Czech_Republic" title="Czech Republic">Czech Republic</a>. In <a href="/wiki/Prague" title="Prague">Prague</a>, evidence of such a duty is documented since 1838.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup> The decree of the government of the <a href="/wiki/Protectorate_of_Bohemia_and_Moravia" title="Protectorate of Bohemia and Moravia">Protectorate of Bohemia and Moravia</a> No. 1/1943 Sb. said that sidewalk cleaning in residential areas of municipalities with more than 5000 inhabitants, of district cities and of other specified municipalities is a duty of the owner or user of the contiguous land. The municipality was empowered to undertake this duty at the expense of the contiguous land owner. The Czechoslovak Road Act No. 135/1961 Sb. (§23) adopted such legal regulations for all municipalities, but municipality offices could modify them. The new Road Act of the Czech Republic, No. 13/1997 Sb. (§9 art. 4) left this enactment in place and stated that maintenance of a road, path, track etc. is an obligation of its owner without any exception. Despite this, §27 art. 4 attached to the owner of contiguous land the liability for harm caused by defects of cleaning. In its 2002 and 2003 annual reports, the <a href="/wiki/Ombudsman#Czech_Republic" title="Ombudsman">Czech Public Defender of Rights</a> made a claim for there being a discrepancy between the theoretical and the practical interpretations of the act and recommended that an unequivocal formulation be enacted. This discrepancy was repeatedly handled by the courts, and the Supreme Administrative Court on 27 June 2005 and the Constitutional Court on 3 January 2007 each stated that the cleaning duty results indirectly from the stated liability for harm. Those who impugn the duty argued that it is a residue of feudal corvée or of the totalitarian Nazi and communist regimes, that nowadays, compulsory labour mandated by law is in conflict with the <a href="/wiki/Charter_of_Fundamental_Rights_and_Basic_Freedoms" class="mw-redirect" title="Charter of Fundamental Rights and Basic Freedoms">Charter of Fundamental Rights and Basic Freedoms</a> and that systematic municipal cleaning is more effective than cleaning by individuals. On 6 December 2007, the <a href="/wiki/Senate_of_the_Czech_Republic" title="Senate of the Czech Republic">Senate of the Czech Republic</a> proposed at the instance of its Constitutional Committee to remove the controversial article from §27 of the Road Act of 1997. The Czech Government gave support to it by a narrow majority. In a previous vote and after heated debate, the <a href="/wiki/Chamber_of_Deputies_of_the_Czech_Republic" title="Chamber of Deputies of the Czech Republic">Chamber of Deputies of the Czech Republic</a> had sanctioned this change by a margin of 116 to 31 amongst the 190 members present. Since 16 April 2009, the changes made by Act No. 97/2009 Sb. mandate that sidewalk cleaning is an obligation only of the owner of the walkway or road, i.e. generally the municipality. Despite the abolition of the duty, many people, including its opponents, declared that they will continue the winter cleaning of municipal sidewalks and paths, but instead will do so voluntarily and on their own behalf. </p><p>As was mentioned during the discussion in the <a href="/wiki/Parliament_of_the_Czech_Republic" title="Parliament of the Czech Republic">Czech Parliament</a> in a statement by the Czech Association of Cities and Municipalities, a similar duty belongs to owners of contiguous land exists in many other modern countries, e.g. Austria, France, the United States and some cities in <a href="/wiki/Bavaria" title="Bavaria">Bavaria</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Clearing_by_contractors">Clearing by contractors</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Snow_removal&action=edit&section=4" title="Edit section: Clearing by contractors"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:TahoeWorkz.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/83/TahoeWorkz.jpg/220px-TahoeWorkz.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/83/TahoeWorkz.jpg/330px-TahoeWorkz.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/83/TahoeWorkz.jpg/440px-TahoeWorkz.jpg 2x" data-file-width="2448" data-file-height="1632" /></a><figcaption>Clearing a residential driveway in <a href="/wiki/Incline_Village,_Nevada" title="Incline Village, Nevada">Incline Village, Nevada</a></figcaption></figure> <figure class="mw-default-size" typeof="mw:File/Thumb"><span><video id="mwe_player_1" poster="//upload.wikimedia.org/wikipedia/commons/thumb/c/ca/Video_of_snow_removal_in_Tartu.webm/220px--Video_of_snow_removal_in_Tartu.webm.jpg" controls="" preload="none" data-mw-tmh="" class="mw-file-element" width="220" height="124" data-durationhint="43" data-mwtitle="Video_of_snow_removal_in_Tartu.webm" data-mwprovider="wikimediacommons" resource="/wiki/File:Video_of_snow_removal_in_Tartu.webm"><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.480p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="480p.vp9.webm" data-width="854" data-height="480" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.720p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="720p.vp9.webm" data-width="1280" data-height="720" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.1080p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="1080p.vp9.webm" data-width="1920" data-height="1080" /><source src="//upload.wikimedia.org/wikipedia/commons/c/ca/Video_of_snow_removal_in_Tartu.webm" type="video/webm; codecs="vp8, vorbis"" data-width="1920" data-height="1080" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.240p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="240p.vp9.webm" data-width="426" data-height="240" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.360p.vp9.webm" type="video/webm; codecs="vp9, opus"" data-transcodekey="360p.vp9.webm" data-width="640" data-height="360" /><source src="//upload.wikimedia.org/wikipedia/commons/transcoded/c/ca/Video_of_snow_removal_in_Tartu.webm/Video_of_snow_removal_in_Tartu.webm.360p.webm" type="video/webm; codecs="vp8, vorbis"" data-transcodekey="360p.webm" data-width="640" data-height="360" /></video></span><figcaption>Video of snow removal on Rüütli street in Tartu, Estonia (December 2021)</figcaption></figure> <p>Hiring a contractor with a <a href="/wiki/Winter_service_vehicle" title="Winter service vehicle">winter service vehicle</a> or a shovel. </p><p>In many high elevation or heavy snow accumulating areas, companies with snow removal equipment offer to provide services to remove the snow. Contractors may work on a per-time basis, full season contract, or will-call status. Per-time service (or per-push) is usually invoiced monthly and customers will be charged for each time services are provided. Some companies will charge per-time and per-inch where the depth of the snow is even taken into account. A full season contract is quoted and paid upfront at the start of the season and services will be provided automatically according to the contracted terms. Terms may sometimes differ between companies. For example, some full season contracts will expire after a certain amount of trips where others are unlimited. And finally, will-call service is where the client makes contact with the snow removal company to initiate a single clearing. This is not an automatic service and charges are usually higher for will-call jobs. </p><p>Snow removal services may include driveway and parking area snow removal, walkway and deck handwork, and roof clearing. Allowing snow to accumulate - especially on roofs where the weight of the snow may cause the structure to collapse - can be very dangerous. Contractors use hand shovels, walk behind snowblowers (or snow throwers), truck plows, skid-steers, light-weight tractors, and heavy front-end loaders. Many times, these machines will require use of tire chains to perform their tasks. Snow may be pushed by plowing methods or blown to an area of the property by snowblowers. Contractors may apply sand or salt in some locations to help melt ice accumulations. </p><p>Many snow removal contractors will require installation of snow poles or snow staking along the driveway. This is to keep equipment out of the landscaping and to help identify the perimeter of an area. </p> <div class="mw-heading mw-heading2"><h2 id="Clearing_by_municipalities">Clearing by

regular snowfall maintain a fleet of snow clearing vehicles. The first to be dispatched are <a href="/wiki/Winter_service_vehicle#Gritter" title="Winter service vehicle">gritters</a> who do some plowing but also salt the road. The salt, via <a href="/wiki/Freezing_point_depression" class="mw-redirect" title="Freezing point depression">freezing point depression</a>, helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, <a href="/wiki/Front_end_loader" class="mw-redirect" title="Front end loader">front end loaders</a> with snowplow attachments, and <a href="/wiki/Grader" title="Grader">graders</a> cover every street pushing snow to the side of the road. Salt trucks often then return to deal with any remaining ice and snow. The trucks generally travel much faster than the plows, averaging between 30 and 40 kilometers per hour. Most cities thus have at least twice as many plows as trucks. Smaller narrow body plows, with <a href="/wiki/Caterpillar_tracks" class="mw-redirect" title="Caterpillar tracks">Caterpillar tracks</a> or huge snow tires salt and clear <a href="/wiki/Sidewalk" title="Sidewalk">sidewalks</a> in some cities, but in many others with less snowfall and/or less pedestrian traffic individuals are tasked with clearing the sidewalk in front of their homes. <a href="/wiki/Ecological" class="mw-redirect" title="Ecological">Ecological</a> movements often oppose this use of salt because of the damage it does when it eventually washes off the roads and spreads to the environment in general. Credit for the concept that municipalities should remove snow from public roadways usually goes to <a href="/wiki/Edward_N._Hines" title="Edward N. Hines">Edward N. Hines</a>, a celebrated early 20th century transportation thinker who also was the first to put a painted center line stripe on an automobile-era road. </p><p>In cities where snow steadily accumulates over the winter it is also necessary to remove the piles of snow that build up on the side of the roads known as <a href="/wiki/Windrow" title="Windrow">windrows</a> or snowbanks. There are a number of methods of doing this. <i>Pulling snow</i> is done when temperatures rise high enough for traffic to melt snow. The windrows are then broken up and spread over the road. <i>Casting</i> is the moving of snow by means of a shovel or plow to nearby public lands. On boulevards or highways <i>winging back</i> is done, which consists of pushing the snow banks further from the road. The most expensive option, but necessary when there are no nearby places to dump the snow, is to haul it away (known as the loading stage). This is most often done by large self-propelled snowblowers that gather the piles of snow at the side of the road and load it into <a href="/wiki/Dump_truck" title="Dump truck">dump trucks</a>. The snow is then dumped on the outskirts of town, or in a nearby lake, river or harbor. (Some jurisdictions have banned dumping snow into local bodies of water for environmental reasons since the collected snow is contaminated with melting salt, motor oil, and other substances from the roads they were removed from.) <a href="/wiki/Snowmelter" title="Snowmelter">Snow melting machines</a> may be cheaper than moving snow, depending on the cost of fuel and the ambient temperature.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> </p><p>The windrows created by the plows in residential areas often block driveways and imprison parked cars. The snow pushed there by any plow is a dense, packed version of "normal" fallen snow. When the temperatures are significantly below freezing this packed snow takes some of the characteristics of solid ice. Its removal is nearly impossible without mechanical means. Recently, windrows created in residential neighborhoods by city operated snow plows have resulted in the snow plow operators being assaulted by angry homeowners. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Chasse_neige.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/ca/Chasse_neige.jpg/220px-Chasse_neige.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/ca/Chasse_neige.jpg/330px-Chasse_neige.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/ca/Chasse_neige.jpg/440px-Chasse_neige.jpg 2x" data-file-width="512" data-file-height="384" /></a><figcaption>A street plow in <a href="/wiki/Quebec_City" title="Quebec City">Quebec City</a>, Canada</figcaption></figure> <p>The largest roads and highways are the first to be cleared; roads with steep hills or other dangers are also often a priority.

Some communities have standing snow emergency rules in winter, in which vehicles may not be parked on streets overnight, whether it snows or not. After smaller snow storms only main roads are cleared while residential ones are left to be melted by passing traffic. Decisions on immediate removal versus "natural melting" can be hard to make because the inconvenience to citizens and the economy in general must be weighed against the immediate effect on the snow removal budget at that particular moment in the season. </p><p>It is estimated that Canada spends $1 billion annually on snow removal.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> In large cities with heavy snowfalls like <a href="/wiki/Montreal" title="Montreal">Montreal</a> and <a href="/wiki/Ottawa" title="Ottawa">Ottawa</a>, the snow clearing expense for each season is an important part of the seasonal public works budget and each snow storm provokes a major logistical operation involving thousands of employees working in shifts 24 hours a day.

Reflective traffic <a href="/wiki/Lane_marker" class="mw-redirect" title="Lane marker">lane markers</a> embedded in the roadbed is not possible (or much harder) due to risk of damage by plows. Access to snow dumping locations (e.g. ravines) by heavy equipment is also planned. </p><p>The employees who take part in snow removal are generally the same workers who do road maintenance work during the summer months, but in some US cities garbage trucks are also equipped with plows and used for snow removal. Many smaller US communities sign contracts with insurance companies, under which the insurance company assumes the risk of a heavy winter. The insurance company of course sets the rates such that averaged over time they will make a profit; the town is willing to overpay for snow removal in mild winters in order to avoid the risk of running dramatically over budget in the occasional severe winter. </p><p>Large organizations such as <a href="/wiki/University" title="University">universities</a> and <a href="/wiki/Airport" title="Airport">airports</a> also often have their own mechanized snow clearing force.
