This pathway must be shown, dimensioned, and labeled on the plans.

An exterior accessible route that shall conform to 2017 ICC A117.1 Sections 402 and 403 and City of Tucson Inclusive Home Design Ordinance. The current plans to no reference a material nor show a connection to ROW sidewalk or Parking area proposed. Ensure dimension the path at the minimum 4-feet required. 2. As currently shown, there is no direct accessible route proposed from the front door of the new Dwelling to the driveway nor to the garage/parking area.
