Livestock and Confinement Feeding Operations in Crawford County, Iowa

Why this matters more in Crawford County specifically

Crawford County's economy has been shaped by large-scale livestock processing for decades. Denison's meatpacking plant opened in 1961 as the first facility built by Iowa Beef Packers (IBP), a company whose innovations in boxed-beef processing reshaped the American meatpacking industry nationally; Tyson Foods acquired IBP in 2001 and operated the Denison plant as Tyson Fresh Meats until closing it in August 2015, eliminating roughly 400 jobs amid a nationwide cattle-supply shortage. Smithfield Foods, the world's largest pork producer, has since been reported as the county's largest employer, consistent with Crawford County's continued significance as a hog-production area in a state that itself holds roughly a third of the nation's total hog inventory. We could not independently verify a specific, current hog or cattle head-count figure for Crawford County against USDA's county-level agricultural data within this research pass -- treat any specific inventory number you encounter elsewhere as something to check against USDA NASS Quick Stats or the most recent Census of Agriculture county profile rather than as settled fact.

The Master Matrix: an annual, opt-in county review layer

Iowa's Master Matrix (Iowa Code 459.305) is a statewide scoring system used to evaluate proposed large confinement feeding operation structures against 44 criteria covering facility design (things like manure-storage type, setback distances beyond the state minimum, and odor-control technology), environmental practices, and community/neighbor-engagement features. A county doesn't participate in Master Matrix scoring automatically -- its Board of Supervisors must affirmatively adopt a construction-evaluation resolution under Iowa Code 459.304(3) to opt in, and that adoption is a year-by-year decision rather than a permanent policy.

Crawford County's own published board-meeting minutes confirm the Board of Supervisors adopted this construction-evaluation resolution both in January 2024 and again in January 2026, indicating an established, recurring practice of opting in to Master Matrix review here -- though this doesn't guarantee the county will adopt the resolution again in any future year, since it's a fresh vote each time. When the resolution is in effect, any construction permit application for a proposed confinement feeding operation structure that comes before the Board during the covered period is scored against the Master Matrix, and the county's supervisors submit a formal recommendation on the application to the Iowa DNR, which retains final permitting authority.

What this means whether you're near a CAFO or planning one

If you're evaluating land near an existing or reportedly-planned confinement operation, the Master Matrix construction-evaluation resolution is the mechanism through which Crawford County has a formal, scored voice in whether and how that facility gets built -- it's worth asking the Board of Supervisors directly whether a specific nearby application went through Master Matrix review, what score it received, and what conditions (if any) the county attached to its DNR recommendation. If you're the one planning to build a confinement facility, confirm the current year's construction-evaluation-resolution status before assuming the same review process (or the same scoring emphasis) that applied to a prior year's application still governs.

Either way, Master Matrix scoring and DNR's ultimate permitting decision are state-level processes layered on top of, not instead of, standard Iowa manure-management and construction-permit requirements that apply to confinement operations statewide -- ask the Iowa DNR directly about the underlying permit requirements if you're the one proposing a facility, since county-level Master Matrix review is an additional local input rather than the entire permitting pathway.

What to verify

1. Confirm with the Crawford County Board of Supervisors whether the current year's Master Matrix construction-evaluation resolution has been adopted, since it is a year-by-year decision.
2. For land near a specific existing or proposed confinement facility, ask the Board of Supervisors whether that facility went through Master Matrix scoring, what score it received, and the substance of the county's recommendation to Iowa DNR.
3. Check current, precise livestock-inventory figures for Crawford County directly against USDA NASS Quick Stats or the latest Census of Agriculture county profile rather than relying on a secondary or dated figure.
4. If you are the one proposing a confinement facility, contact Iowa DNR directly for the full underlying construction-permit and manure-management-plan requirements, since county Master Matrix review is a supplemental local layer rather than the complete permitting process.
