GRADING: LEVELLING OR LANDFORMING?

| COREY DAWSON + ROBERT CORRY

"HOMO THE HOMOGENIZER"

ARE LANDFORMS BECOMING MORE ORDERLY BY DESIGN?

FR_ RÉSUME
HOMO L'HOMOGÉNÉISATEUR_Les modelés deviennent-ils plus
ordonnés ou volontairement plus chaotiques?
Les architectes paysagistes sont-ils les « homogénéisateurs »
du paysage ou s'efforcent-ils de créer de la complexité? Robert
Corry et Corey Dawson ont cherché des indices de « modelé » : une
méthode de terrassement créant des reliefs en pente où alternent
les courbes concaves et convexes - le genre de formes irrégulières,
de dénivellations complexes et de terrains naturellement chaotiques
que l'on trouve sur les terrains vierges. C'est en fait, un terrassement
qui paraît anarchique mais qui est plus fonctionnel d'un point de vue
géologique, écologique et hydrologique.

WES JACKSON of The Land Institute (landinstitute.org) has described
Homo sapiens as "Homo the homogenizer," arguing that we simplify
the systems we encounter, be they biological, cultural or physical.
In fact, in LA work today, biodiversity and hydrologic complexity are
increasingly recognized, as landscape architects design for pollinators,
songbirds, native plants and rainwater infiltration.
Nonetheless, overall, the diversity of land forms commonly remains
overlooked. A well-used text in professional education, Landscape
Architectural Graphic Standards, defines a landscape architect as a
designer that "creates level areas for intensive use, such as parking
lots and playing fields." The 2007 text, written by Leonard J. Hopper, is
describing a fundamental skill learned in accredited programs: grading

terrain. In the same year, however, Horst Schor and Donald Gray added
a sustainability dimension to the definition in their book, Landforming,
when they coined the term "landform grading."
Landforming is a grading approach that creates slope forms with
sequences of concave and convex shapes - the kind of irregular shapes,
complex slopes and naturally messy terrains found in untrodden
ground. It is, effectively, grading that looks messy but is geologically,
ecologically and hydrologically functional, since it creates ecological
niches with differing wind and sun exposure, differing soil moisture,
and hence differing microclimates. Such landforms tend to blend
into natural profiles and contours, and offer increased stability and a
complex visual appeal.
According to landscape preference theory and empirical study,
humans prefer hilly terrain over flat ground. Complex landform shapes
result in vegetation diversity and fluvial systems that are intriguing.
Naturally hilly landforms provide privacy, vista opportunities, and
feelings of mystery that are different from the orderly and planar
surfaces existing in most human settlements.
