Canyon County officials are moving forward with proposed changes to agricultural zoning ordinances aimed at slowing the pace of land divisions in the county’s farmland, following a public comment session held Wednesday. The measure targets administrative land divisions—property splits that bypass the standard public hearing process—which have fragmented nearly 1,100 parcels across the county’s agricultural zones in just five years.
On August 20, the county held its first public hearing on the proposed revisions to rules governing how agricultural land can be subdivided, a key concern for residents and officials worried about the erosion of farming country in the Nampa, Caldwell, and broader Canyon County region. Between 2020 and 2025, administrative land divisions in agricultural zones created 379 new parcels—generating 1,028 additional properties in total—threatening the viability of productive farmland and the rural character that defines much of the Treasure Valley.
What the Proposed Changes Would Do
The proposed ordinance revisions would eliminate two categories of administrative divisions: non-viable land divisions within agricultural zones and administrative splits of lots in subdivisions platted before 1979. Significantly, the overall number of administrative land divisions permitted annually would remain unchanged under the proposal, meaning the county is not seeking to halt such divisions outright but rather to make the remaining divisions more intentional and better-coordinated with local service providers.
The changes introduce clearer definitions for key terms such as “lot,” “parcel,” “original parcel,” “agricultural-only parcel,” “buildable,” “legal access,” and “historic lot.” Updated application requirements would mandate that landowners submit irrigation plans alongside division requests. New property-owner notification requirements and updated standards for agricultural-only parcels are also included.
Under the revised rules, applicants would be required to obtain formal acknowledgments from highway districts, fire districts, irrigation districts, and Southwest District Health before divisions are approved. These safeguards aim to ensure that new parcels created in agricultural zones can be adequately serviced and do not create unforeseen burdens on local infrastructure or emergency response systems.
Community Feedback Drives the Effort
The proposed changes emerge from months of community engagement. Canyon County conducted a summer 2025 survey and held community workshops seeking resident input on agricultural preservation. The feedback was consistent: residents want stronger protections for farmland, clearer division rules, and limits on the proliferation of small parcels that undermine agricultural operations.
As of June 2025, Canyon County had 20,638 parcels zoned agricultural outside city limits. The pace of administrative divisions—averaging roughly 76 per year from 2020 to 2025—has raised alarm among agricultural interests and county planners concerned that excessive fragmentation will price out working farmers and convert productive acreage into hobby properties or future development sites.
Impact on Canyon County Agriculture
The proposed ordinance reflects a broader challenge facing Idaho’s agricultural heartland. As land values rise and rural parcels become attractive to non-farming buyers, the subdivision process—particularly the streamlined administrative route that requires no public hearing—has accelerated the breakdown of large agricultural holdings into smaller, often non-viable farming units. These changes aim to preserve the working agricultural landscape that remains central to Canyon County’s economy and identity, supporting dairy operations, sugar beet growers, and other agricultural enterprises that depend on contiguous, productive farmland.
For farmers and ranchers across Nampa, Caldwell, and surrounding agricultural areas, the proposed rules represent an effort to slow the tide of piecemeal development and protect remaining opportunities for agricultural succession and expansion. The measure is also consistent with recent state-level efforts to support agricultural resilience, including disaster loan programs for farms and water management protections for agricultural users.
What Comes Next
A second public comment session is scheduled for November 5. Residents and interested parties who wish to submit written comments must do so at least 10 days before that date—by October 26—to ensure they are part of the official record.

Canyon County officials have signaled their intention to finalize the ordinance revision following the second public hearing, making agricultural land preservation a defining regulatory priority heading into 2027.
