Exactly the same as last year, 89 of Iowa’s 99 counties plan to use the master matrix to evaluate construction permit applications and proposed locations for animal confinements during the next 12 months. Ten counties did not pass a construction evaluation resolution. So Davis, Des Moines, Keokuk, Lee, Mahaska, Osceola, Plymouth, Wapello, Warren and Washington counties will not be using the master matrix this year.
