Renewal of U.S. 18/U.S. 218/Iowa 27 highway corridor preservation in Floyd County

Posted on: February 18, 2016

AMES, Iowa – Feb. 18, 2016 – The Iowa Department of Transportation is providing public notice of a corridor preservation zone for future improvements to the U.S. 18/U.S. 218/Iowa 27 corridor in Floyd County, beginning at March Avenue south and extending east to the Floyd County Road B-35 interchange. A preservation zone means the Iowa DOT may need to acquire additional right of way or property rights within the designated area.

The Iowa DOT implemented corridor preservation for this area March 4, 2010, which was renewed in March 2013. It is the intent of the Iowa DOT to continue to utilize this corridor preservation for potential future development purposes.

This notice shall be valid for a period of three years from the date of notification (March 3, 2016) of the city or county, and may be refiled by the Iowa DOT every three years.

This notice includes a depiction of the corridor preservation area on a map, which is available at To submit a comment online, go to: Width of the corridor preservation zone varies depending upon the location within the corridor.

Per Iowa Code 306.19(5), each city and county within the designated preservation corridor shall provide written notification to the Iowa DOT of: (1) an application for a building permit for construction valued at $25,000 or more; (2) submission of a subdivision plat; or (3) proposed zoning change within the area. Notification must be provided to the Iowa DOT at least 30 days prior to granting the proposed building permit, approving the subdivision plat, or changing the zoning. Written notification shall include all pertinent information regarding the proposed permit, plat, or zoning change.

If the Iowa DOT, within the 30-day period, notifies the city or county in writing that the Iowa DOT is proceeding to acquire all or part of the property or property rights affecting the area, the city or county shall not issue the building permit, approve the subdivision plat, or change the zoning. The Iowa DOT may apply to the city or county for an extension of the 30-day period. After a public hearing on the matter, the city or county may grant an additional 60-day extension of the period.

The Iowa DOT shall begin the process of acquiring property or property rights from affected persons within 10 days of the Iowa DOT’s written notification of intent to the city or county.
