Gates are most useful in residential areas to avoid leaving berms across driveways. Currently, the City of Spokane Valley utilizes contracted graders to plow residential areas within the City. Since the City does not own the graders, implementing the use of gates would require contractors to purchase additional equipment. At this time the companies that the City contracts with do not own graders with gates. The approximate cost of a gate is $25,000.
The use of gates increases the time to be able to complete plowing since the grader has to operate at a lower rate of speed to be effective.
The City is observing the use of gates in our neighboring cities and will continue to evaluate the usefulness of this piece of equipment.
