County commissioners agreed earlier this month to put a $50 million bond measure before voters Nov. 7. Proceeds from the tax, which would cost property owners an estimated $8 per $100,000 of assessed value or the median home owner in the county about $29 annually, would be set aside to fund the purchase of undeveloped land, with particular attention paid to the Rathdrum Prairie. That area of farmland separating the cities of Rathdrum, Post Falls, Hayden and Coeur d'Alene has been the site of rampant growth in recent years, including the approval in March of a 2,800-home development project that will link Post Falls and Coeur d'Alene.
