The city of Denver is poised to spend more than $5 million on 200 prefabricated Pallet shelter homes toward Mayor Mike Johnston’s goal of providing shelter for 1,000 people living homeless on the city’s streets by the end of the year. The administration is eyeing paved lots as the future landing places for the easy-to-assemble, temporary shelters, Cole Chandler, the mayor’s top homelessness advisor, told a City Council committee Tuesday. But just where those paved lots — and undeveloped “raw dirt” lots that Chandler said are being considered for villages of manufactured tiny homes — will be located remains unknown outside of executive sessions and private talks between city officials and property owners. The council’s finance and governance committee on Tuesday signed off on a $7 million master purchase order with Everett, Washington-based Pallet.
