Easements not parallel to a boundary or lot line shall be shown by center line distance, bearing, and width or by easement boundary bearings and distances. Where easement lines are parallel to boundary or lot lines, the boundary or lot line distances and bearings are controlling. Where the exterior boundary lines show bearings or lengths that vary from those recorded in abutting plats or certified surveys there shall be the following note placed along the lines, “recorded as (show recorded bearing or length or both).” 236.20(2)(d)(d) Blocks, if designated, shall be consecutively numbered, or lettered in alphabetical order.

When a circular curve of 30-foot radius or less is used to round off the intersection between 2 straight lines, it shall be tangent to both straight lines. It is sufficient to show on the plat the radius of the curve and the tangent distances from the points of curvature to the point of intersection of the straight lines. 236.20(2)(L)(L) When strict compliance with a provision of this section will entail undue or unnecessary difficulty or tend to render the plat or certified survey map more difficult to read, and when the information on the plat or certified survey map is sufficient for the exact retracement of the measurements and bearings or other necessary dimensions, the department or, in 1st class cities, the city engineer may waive such strict compliance. 236.20(3)(3) Name, location and position.
