On 10 June 1907, the Melbourne City Council appointed Morton, then serving as the assistant building surveyor, to the new position of City Architect, with the role of supervising all Melbourne Corporation construction projects. In October 1915, when the City Surveyor, A. C. Mountain, retired, the Melbourne City Council approved the abolition of the positions of City Architect and City Surveyor, and their amalgamation into the single position of City Engineer and Building Surveyor, with Morton as the appointee. A major achievement as Morton's long tenure as City Engineer was his campaign to spend £5,000,000 to surface streets with wood-blocks to help end dust nuisance. Morton supervised all significant building projects of the Melbourne City Council including the administration buildings of the
Melbourne Town Hall (1909) and the Grand Stand of the
Arden Street Oval (1928). On 27 March 1923, Morton was appointed to serve as a Member of the Board of the
Metropolitan Town Planning Commission, and in this role advised the Victorian state government on the future planning and development of metropolitan Melbourne. The Commission produced the foundational town planning document, the
Plan of General Development, in 1929. ==Political career==
