The Dickson Planning Commission will hold a called session Monday to review an amendment to the city’s zoning ordinance to allow mixed-use development in downtown. The proposed change was prompted by a planned development that would include both commercial and residential uses being considered for the southeast corner of College and Main streets where several buildings were damaged by fire and torn down. While the current B-2 zoning allows residential use on an upper floor and commercial use on a lower floor, the proposal by Anthony and Michael Curcio would include residential use on multiple levels. The final draft for the revisions must get Planning Commission approval before it can be sent to the Dickson City Council for a public hearing. The Planning Commission also is expected to schedule a public hearing for March 26 on the adoption of a revised land use plan for the city that Planning and Zoning Director Jason Pilkinton says extends the city’s projections through 2030. The special session of the Planning Commission is set for noon Monday at Dickson City Hall.
