6. I don't want to have my road paved but I would like to have my road maintained.

Due to current air quality standards within the non-attainment area (PM-10 boundary) and legal restrictions, only roads that have been paved to county standards will be accepted for maintenance by the County. Outside the PM-10 boundary, the county can and will form a Maintenance Improvement District. However, this requires that maintenance be performed through private contract.

7. How often is the road graded?

The road is graded approximately four times per year. Return to County Improvement Districts

8. What if I can't make the payments?

If an assessment becomes delinquent, the district is obligated to sell the property covered by that assessment to pay the special assessment bonds. The buyer is required to hold the lien for a minimum of one year before applying for a Superintendent of Streets deed of the property. During that period, the assessment lien must be paid in full, plus penalties. Once a deed is issued, the buyer has control of its redemption value. For districts on the tax roll, it is considered the same as delinquent taxes. Return to County Improvement Districts
