In 2000, Wayne County purchased 14 new high-speed
plows for use in rural areas. These plows can throw snow up to 75 feet from
the road, which helps keep the road and its shoulders clear more effectively
Wayne County purchased this vehicle from
Houghton County in the upper peninsula and is the only county
in southeast Michigan to own one. Think of it as a driving
snowblower. The County uses this to clear areas that plows
cannot reach, or to throw snow from a freeway shoulder onto
the embankment, so stalled vehicles can have safe haven on
the shoulder and not tie up an active lane of traffic.
Wayne
County was the pioneer in adding Global Positioning Satellite
technology to its salt trucks and is now part of a tri-county
effort to equip all trucks from Wayne, Oakland and Macomb counties,
as well as the city of Detroit, with this advanced technology.
Trucks fitted with the equipment can send back to the yard
such information as air and pavement temperature, how much
salt is being spread, if the plow is in use, as well as the
vehicles location and direction. This information will be extremely
useful to dispatchers who must make "on the fly" decisions
about how to deploy their trucks as storm conditions change.
The good news is that Wayne County is able
to tend to all of its 462 miles of State freeways and trunklines
AND all of its 700 miles of paved primary roads immediately from
the beginning of a snowstorm.
In order to do this, the County has established approximately 130 individual
salting/plowing routes that are addressed simultaneously from the time
snow starts falling and sticking. Each driver knowing exactly where he
or she is to be salting [even if it is not their normal route] allows
the County to cover more than 1,100 miles of major roads in about 90 minutes.
Of course, this can vary, depending on weather and traffic conditions.
The effectiveness of the County's salt routes are re-evaluated each year
and changes are made, when necessary, to provide improved service.
History shows us that more than 98 percent of snow "events" that
occur in Wayne County bring fewer than six inches of snow, having one truck
on each route is acceptable, well, 98 percent of the time. But as we have
seen in recent years, Mother Nature likes to remind us who's the boss.
When enough snow falls that one truck per route
is not able to effectively keep its route safe and clean, we
have to reprioritize, which means consolidating more trucks onto
fewer routes. Rather than having all of its routes insufficiently
cleared, the County's approach will be to "Team Plow" its
highest priority routes, which typically will be freeways and
other state roads, as well as some of the most heavily traveled
county roads.
While these trucks are able to make the high-priority
routes clear much faster this way, it does mean that some of
the lesser traveled primary roads will not see any attention
for a period of time. But once the high-priority routes are cleared,
the teams can be re-deployed to plow the second tier of roads.
IT IS THE COUNTY'S P0LICY THAT WORK WILL CONTINUE
AROUND THE CLOCK FOR AS LONG AS IT TAKES TO CLEAR ALL OF ITS
MAJOR ROADS DOWN TO BARE PAVEMENT.
Once all of the 1,100-plus miles of major roads are cleared and safe, workers
will begin to make their way into township subdivisions - if the accumulated
snow has reached five or six inches. [Unlike townships, cities have their
own snow removal program]. Crews will work continuously until each of its
700-plus miles of secondary streets has been plowed. Of course, because
the county's competing responsibilities mean that it may take several days
to reach the subdivisions, many communities choose to hire a contractor
who will be able to respond more quickly. While this surely can be disappointing
to residents along these streets, the county simple does not have the resources
to fund another tier of snow removal forces.
Along the county's secondary roads, the county also places a priority on
school bus routes and a four-point system called the RICH system, which
stands for
