9.c Discussion on Dust Control proposals
Staff Report
Date of Meeting: March 21, 2017
To: City Council
From: Adam Hawkinson, Director of Public Works
Re: Dust Control 2017
Background: The City has historically applied Calcium Chloride to most of its gravel
roads as a means of dust control. The City also includes the roads of
Cedar Cliff in the quotes for applications. If treatment is requested by
Cedar Cliff residents the city charges them for this service. They have
requested this service again for 2017.
Proposal: Staff is proposing to apply Calcium Chloride to the selected gravel roads
on the proposal. Two applications should be applied as recommended by
the Minnesota Department of Transportation. This helps prolong the loss
of dust and fine particles. The loss of fine particles causes the loss of
larger aggregate and roads to deteriorate faster.
Fiscal Impact: The 2017 budget has $25,000 allocated in the contractual road
maintenance fund for dust control. The low bid is $0.89.4 per gallon for a
base price of $14,753.68 for the first application and $7,377.29 for the
second application. Cedar Cliff’s financial responsibility would be
$1,882.80 for the first application and $941.40 for the second application.
Options: 1) Award the Calcium Chloride application for dust control to Northern
Salt Inc.
2) Award the bid to one of the others per their quote(s)
3) Award the chloride application for dust control but limit the roads the
applications occur.
4) Do not award the chloride application for dust control.
Recommendation: Option 1
