The tracks had been there since 1886, and when they were torn up 100 years later, Houtz thought it was an opportunity to celebrate another 100th anniversary-the Centennial of the State of Washington.  The idea of a flower garden running in the former railbed for 13 blocks took hold with the help of many volunteers, donated topsoil and discounted railroad ties.

     The idea of an "adopt a block" program is credited to resident Darrel Bartels, who suggested that local organizations take responsibility for planting and maintaining one-block sections of the garden.  Each block features five trees, five repeating shrubs, and large rocks for continuity, but each also is given its own "personality" with addition  of a variety of colorful flowers and garden landscaping.

     Pomeroy's Centennial Boulevard flower garden is a pleasing and memorable landmark in Pomeroy, and one that visitors to the county should enjoy for a long time. The project received the attention and praise of the state's former First Lady, Jean Gardener and was publicized by Sunset magazine.
