(B) The function and the duty of the Planning and Zoning Commission shall be to make, or cause to be made, and to recommend a Comprehensive Plan for City Council adoption which guides the physical development of the city. Such plans may relate to the comprehensive planning of the city. Such plans and the accompanying maps, plats, charts, and descriptive matter shall show the Planning and Zoning Commission's recommendations for the development of the territory, including among other things the general locations, character and extent of streets, alleys, ways, viaducts, bridges, railroads, terminals, school grounds, fire station sites, or any other public grounds or public improvements, and the removal, relocation, widening or extension of such public work then existing. As the work of making the whole Comprehensive Plan progresses, the Planning and Zoning Commission may from time to time amend, extend or add to the plan.
