Reverse Bench
This is needed when slopes are over 15' tall. An erosion control technique where the slope is
notched to create a valley that collects water runoff to avoid massive amounts of water rushing
down a hill all at once
Convex Slope
Contours Closer together at the bottom and wider apart at the top. Slope protudes out and water
will pass over
, Concave Slope
Contours closer at the top and wider apart at the bottom. Slope will dip in and create a place for
water to collect

used during design phase to show how the site will be developed, including building placements
and how a projects construct will be phased (if applicable)
Survey
A legal document depicting the location, shape and boundaries of a land parcel
Plane
the most common method to draw survey. Shows land as a flat plane
Land Survey
Survey that uses metes and bounds to define the measurements of site and the location of the
property boundaries
