The Austin City Council and the city planning commission will meet at 6 p.m. Monday to discuss changes to the city’s downtown master plan.

The city recently hired a firm to update its master plan after several major projects have been announced in the downtown area. Community Development Director Craig Hoium said downtown master plans are redone whenever unexpected major projects, such as Vision 2020 initiatives like the Austin Utilities plant or the Spam Museum relocation, take place. The last downtown master plan was done in 2005, to accommodate the city’s Main Street Project initiative.

The planning commission will meet at 5:30 p.m. Monday as well, to discuss sign ordinances and a tree preservation request.
