Provide a residential plot plan that meets the requirements found at: https://www.tucsonaz.gov/files/pdsd/forms/Residential_Plot_Plan_Requirements.pdf, to include but not limited to: a. The plot plan shall be drawn at an engineering scale, i.e. 1” = 10’, 1” = 20’. b. Provide a lot coverage calculation on the plot plan that meets the requirements of UDC Article 6.4.3 and the example shown on the Residential Plot Plan Requirements. c. Provide perimeter yard setback dimensions from the proposed storage container to the south & west property lines. d. Show the zoning of the property and all surrounding properties on the plot plan. e. Provide the legal description of the property on the plot plan. 2. Historic review is required and must be approved prior to approval of this building plan.
