Site-GradinG conceptS for a SimpLe
reSidentiaL Lot
This chapter has presented a way to think about site grading as the
application of a variety of signature solutions. The signature solutions
approach is a way to visualize site grading; these solutions are not meant
to be applied as simply as one applies colors selected from a palette to
a canvass. The designer might first consider one or more of these solu-
tions as a means to solving a site-grading problem. In actual application,
designers may not think in terms of signatures, but for the beginning
student it might be helpful to consider them as a way to get started. The
way site grading has been presented in this chapter should not minimize
the complexities challenging the designer in arriving at a practical and
aesthetically pleasing site-grading solution.
In the following examples, different signature solutions are pre-
sented to show how one might approach a site-grading problem. To
decide which is the most practical or desirable solution, the designer
would consider a number of factors. Cost is always a consideration for
selecting what is best, as well as site conditions such as topographic
constraints, and the project program and attendant landform.

Figures 12.17-A through 12.17-C provide a diagrammatic overview of
three signature solutions for solving the site grading of a simplified
residential site. Signature A is an approach that sets the house at the
highest elevation on the site and creates four planes to sheet-drain
storm water away from the building to the edges of the property. Sig-
nature B sets the house at a high elevation then creates two swales to
direct storm water around the building toward the street. This solution
assumes that the property generally slopes from the back to the front.
The signature solution used to solve the grading problem of site C posi-
tions a catch basin at the back of the property to collect storm water
