Plans for biomass in downtown Vancouver may be dead, but the city council on Monday night kept alive a moratorium stopping development at the site.Earlier this year, Clark County announced plans for a biomass plant at West 11th and Harney streets. It stirred controversy that pitted downtown residents and the city council against Clark County commissioners and the private company that would become its partner. The plan was abandoned last month by that company, Schneider Electric.In a move that helped to thwart the plans, the city council passed a surprise emergency six-month moratorium on development in the light industrial overlay zone where the biomass plant would have been built. On Monday, the council agreed to extend that moratorium to Oct. 10, 2012.City councilors said they want to keep the temporary development ban in place to give time to the city’s planning commission to draft new zoning for the light industrial overlay district. Allowing development of a power plant there, they said, clashes with the city’s Vancouver City Center Vision plan, passed in 2007.“Recently, Clark County’s proposal to build a biomass energy facility in the West Government Subdistrict of the downtown brought to light significant inconsistencies between the vision for this subdistrict and the uses that are allowed by the city’s Land Use and Development Code,” a staff report read.
