The purpose of this chapter is to establish the County’s policy and level of service in respect to clearance of snow or ice and maintenance of its secondary road system during the winter months, specifically defined as November through April, pursuant to the provisions of Section 309.67 of the Code of Iowa. This policy and level of service are to be implemented within the amount of money budgeted for this service, and as contained in the County’s secondary road budget as submitted to and approved by the Iowa Department of Transportation and adopted by the Board of Supervisors. The clearing of roads at any cost is not the County’s policy.
