(KNZA)--The city of Hiawatha is making plans for this summer’s chip seal project.

On the recommendation of Street Department Supervisor Nic Siebenmorgen, the City Commission agreed this week to use washed rock for this year’s project instead of haydite.

In addition, the Commission agreed to have the county haul the rock, with the city paying for the fuel and donating labor to the county when needed.

Siebenmorgen said the two moves would save the city more than $12,000.

The city switched to haydite several years ago after residents voiced concerns about the dust created by the washed rock.

To control the dust, Siebenmorgen says plans are to build a spray bar for wetting the rock down after its been applied to the streets.

The city plans to chip seal about 3 ½ miles of city streets this year, which is less than half what the city normally does.
