PART III: Surveys and a City Plan Pittsburgh: Main Thoroughfares and The Down Town District Frederick Law Olmsted report to The Pittsburgh Civic Commission, 1910
Baltimore In Baltimore the work of preparing an accurate and comprehensive topographical and property map was begun in 1893 by a Topographical Survey Commission created for the purpose. The area completely mapped was about thirty square miles although the triangulation necessarily extended over a considerably larger area. The first two-thirds of the area mapped was completed in about two years; the cost, including all field work, office work, draughting, and publication, was about $5,000 per square mile. Allowing for the normally higher costs of all work in New York as compared with Baltimore, and allowing for the fact that the Baltimore figures include little if any street monumenting or final record maps of layout, this figure corresponds very closely with the cost of $10.29 per acre or $6,585.60 per square mile reported from the Borough of Queens.
