Attachment 4 Elevations.pdf

The image appears to be a detailed architectural or engineering elevation drawing for a construction project, specifically focusing on elevations and reference points. The document is handwritten in green and red ink, showing multiple grid-like sections with numerical measurements ranging from -1/4 to +3/8, with designated green and red reference points for different sections labeled as "West" and with a section number 4A9B. The drawing includes multiple grid panels with varying elevation markings, and notations indicate reference points for centerline and drain elevations. The document seems to be a technical schematic used for precise measurement and positioning in a construction or design context.
