Snow & Ice Control Plan

snow flakessnowflakes


The primary purpose of the Snow & Ice Control Plan is to organize snow and ice response efforts so that safe travel routes are available during snowstorms.

I am interested in information regarding:


General Overview:

The City of Longmont's Snow & Ice Control Plan is designed to provide City employees with guidance and direction for maintaining roads during periods of snow or ice. The City's streets are classified by their function for moving traffic. Arterial roads are the principal routes that deliver traffic from collector roads to urban centers and major highways. Collector roads provide access to residential areas and serve to move traffic to and from arterials. Other high priority roads include streets that serve schools, hospitals, and public buildings. The goal of Longmont's Snow and Ice Control Plan is to maintain a safe flow of traffic throughout the City and to ensure that each residential area is in close proximity to a plowed street. Emphasis is also placed on ensuring that emergency services can be provided throughout the City.


My Responsibility as a Citizen:

Residents are advised that in certain areas, snow may be inadvertently plowed onto sidewalks or into driveways due to the narrowness of the roadways. The City's Municipal code stipulates that residents have 24 hours after a storm ends to remove snow and ice from sidewalks abutting their property (LMC 9.04.130). Residents can minimize the need to repeatedly shovel sidewalks by waiting until a storm is over and streets have been plowed.


The Objectives of the Snow Removal Team:

• To have all designated streets in the Snow and Ice Control Plan plowed and sanded within 24 hours after a storm.

• To reduce the cost of snow operations through the acquisition and utilization of efficient equipment, thereby minimizing the cost.

• To divide the City into areas where one truck equipped with a plow and sander can effectively provide snow operations service in each area.

• To sufficiently train an adequate number of personnel to operate all available snow removal equipment.

When Snow Plows are Deployed:

Level One Deployment

• Level one deployment is considered for snow and ice events where accumulation is small and no other storms are expected.

• Selected locations such as overpasses, bridges and shaded areas are treated as needed.
• Full deployment of snow teams is not typical at this level of storm. Deployment occurs as needed, and the primary purpose is to sand or de-ice specific locations with accumulation or areas that have been reported by the Communication Center, Risk Management or residents.

• Staff included in the Operations Division's on-call list is deployed for this level of operation.

Level Two Deployment

• Level two deployment is considered for snow events with accumulations of zero to six inches with the possibility of back-to-back storms.
• The entire snow team is called in for duty. Currently, the team size is 13 staff and trucks per twelve hour shift. There is a thirty-minute response time for staff to report for duty with a twelve-hour work shift until the storm ends. More than one twelve hour shift may be required.
• Operations will consist of plowing, sanding, and de-icing along the identified snow routes.
• Fleet Maintenance mechanics are placed on-call to ensure the plow truck fleet remains operational.
• Limited and/or targeted snow removal operations are possible along the Downtown area and school zones based upon conditions.

Level Three Deployment

• Level three deployment is considered for snow accumulations of six to fifteen inches regardless of single or multiple storm predictions.
• Entire snow team is called for duty. Back to back shifts of twelve hours on and twelve hours off are used to provide continuous snow route coverage.
• Fleet mechanics will be called in for duty to immediately address equipment problems.
• City staff providing back-up to snow and ice operations may be used.
• Private contractors may be contacted to assist City crews.
• School zones are cleared curb to curb.
• Plowing priority will be given to the continuation of critical City services including Trash, Water, Electric, etc., along with emergency response needs.

Level Four Deployment

• Transition from level three to level four is based upon the predicted forecast of snow storms with accumulation of fifteen inches or greater and additional accumulation expected.
• Declaration by the City Manger of a snow emergency and the activation of the City's Emergency Operations Center.

• Incident commander will assume duty. The purpose of the incident commander is to maintain and deploy resources based upon our Snow and Ice Control Plan.
• Logistics officer will be appointed. The logistics officer's role is to process special requests for equipment, contractors or other needs.
• Public Information Officer will assume duty. The PIO's role is to receive and disseminate information, which includes press information.

• Entire snow team called for duty. Back to back shifts of twelve hours on and twelve hours off are used to provide continuous snow route coverage.
• In addition to plowing and sanding designated streets, plowing and sanding of non-designated streets may occur based upon criteria such as snow fall accumulation, availability of funds, emergency vehicle mobility and weather forecasts.
• Back-up and other City staff and resources will be called upon as needed.
• Contractors contacted to assist city crews.
• School zones are cleared curb to curb.
• Fleet mechanics will be called in for duty to immediately address equipment problems.

Deployment; Deployment of the snow response teams requires staff to arrive at the Public Works Maintenance Facility within thirty minutes of being called and teams are expected to be on route within the next 30 minutes.

Street Prioritization:

Priority #1

Serves the hospital, medical clinics, fire stations, City facilities, schools, commuter routes, shopping centers and most arterial and collector streets. This network is also connected to County and State-plowed roads. School zones are plowed curb to curb and are typically completed prior to the school day. Continued plowing occurs during the school day as the snow event is evaluated. This priority also includes the Historic Downtown area.

Priority #2

Serves higher traffic arterial and collector streets not categorized as Priority #1.

Additional Efforts

After major snow storms with heavy accumulation the City has access to additional resources and has developed agreements with the Colorado Department of Transportation and Boulder County to promote the effective use of resources. Additional snow team support for major storms or equipment breakdowns may be supplied by qualified contractors or heavy equipment rentals.

The City of Longmont's Snow & Ice Control Plan is designed to organize reasonable, cost effective maintenance efforts during periods of snow or ice. The City's streets are divided into main and secondary arterials, plus streets that serve schools and hospitals. These areas receive sanding and plowing first. This assures each residential area is in close proximity to a plowed street and that emergency services can be provided.

The Snow Plan is available to citizens that are interested in how this service is conducted.
