Story County has a drop-off site for yard waste and vegetative storm debris from the August 10th storm event. The site is for organic storm debris only (trees-no root balls, brush, and vegetation) and limited to residents of unincorporated Story County (outside all city limits). It is self-haul, drop-off only.

The site is open Monday through Wednesday from 12:00 pm – 4:00 pm and again on Saturday from 8:00 am – 12:00 pm. The final day to drop debris off at the site is Saturday October 31. 

Upon entry to the site, identification or other proof of residence in unincorporated Story County must be shown, and loads will be photographed and logged. Face coverings are recommended when social distancing practices cannot be followed. 

Staff is not available to help unload debris, and residents are encouraged to tie down or cover loads to prevent debris from falling out during transport. Use caution around the heavy equipment at the drop-off sites. PPE Recommended: Safety Glasses, Hi Viz Shirt, Gloves, Long pants, Closed Toed Shoes.

Review of Agriculture Practices

On June 1, 2020, the Governor signed HF2477 and HF2512 into law. The laws had an immediate impact on planning and zoning in Iowa counties as each county’s authority to require review of agricultural exemptions and agritourism requests disappeared, including Story County.f

  • HF2477 eliminates counties’ ability to require conditional use permits, special use permits, special exceptions, or variances for agricultural experiences on a farm where the primary use is agricultural production. Agricultural experiences are secondary uses to agricultural production and are intended to promote or educate the public about agriculture, agricultural practices, agricultural activities, or agricultural products. This new law will require the striking of Story County’s agritourism ordinance and Conditional Use Permit process from the Story County Land Development Regulations. With permit and variance approvals for agricultural experiences gone, so also opportunities for neighbors and other members of the public to express their support or opposition for new or changing agricultural experience projects at a public hearing. 
  • HF2512 states that “a county shall not require an application, an approval, or a fee in order for an ordinance to be deemed inapplicable to land or buildings that are primarily adapted for agricultural purposes,” requiring Story County to change some of its processes. The Planning and Development Department is now supporting a voluntary application submittal process for property owners claiming their land and/or building projects are agriculturally exempt from County zoning requirements. The Department’s review will continue to include referral to Environmental Health when waste water is planned to be generated and a septic system permit is needed, review for impacts on the flood plain, referral to electric service providers regarding overhead electrical line separation standards, and review for potential impacts to easements. 

Please send comments or questions regarding these laws to or call 515-382-7245 for more information.  

New Flowchart for Construction Site Erosion and Sediment Control Requirements

Story County amended its Construction Site Erosion and Sediment Control requirements and Post-Construction Stormwater Management requirements in 2019. All construction projects that disturb under one acre must meet the Construction Site Erosion and Sediment Control requirements. A full set of both erosion control and stormwater management requirements can be found in Chapter 88.05 of the Story County Land Development Regulations.
