Question: Should I show the property lines in the site plan. The lines are in red, is this how you wanted the site plan? 

Yes, please include the property lines in your 300:1 scale drawing. Typically, in AutoCAD the line color sets the printing line weight. We will discuss that in 2-9-21 class. The line type should be either, long dash and two short dashes (for property lines) or just straight long dashes (for lot lines).
