City of N.Van. The dust suppressant used by the City of North Vancouver in lanes is calcium chloride, a salt, put down in flake form. If it is tracked into the house, it will dry to salt and can be vacuumed.
Calcium chloride is harmless and is used all over North America for dust control and ice control.
However, to minimize the use of chemicals, the City has been active in promoting lane paving by the Local Improvement procedure, which has reduced the number of gravel lanes over the past several years. As a taxpayer you can have your lane sprayed by telephoning the City Works Yard at 987-7155 and have your name and lane added to a list which is periodically forwarded to Operations for action. When a sufficient number of lanes are ready for treatment, our contractor will spray the lanes. This is an ongoing process through the summer.
