Abstract

Some of the test questions for the National Council of Architectural Registration Boards (NCARB) deal with the site, including drainage, regrading, and the like. A site is described by its shape and by contours shown on the plan view. Existing structures may be shown on the site. Some questions are most easily scored by examining contours, such as determining if, in regrading the site, the student changed a contour, causing it to pass through an existing structure. However, water flow questions are best scored from a grid of elevations. This document describes a method for creating an elevation grid from a set of contour lines. (21pp.)
