FR_ SOLUTIONS POUR PLANTER DES ARBRES DANS
LES SURFACES DURES DES BOULEVARDS : MANUEL
DES MEILLEURES PRATIQUES : Lorsque DTAH a
reçu de la ville de Toronto la commande d'examiner
les précédents municipaux en matière de croissance
d'arbres de rue dans les trottoirs, la firme a fait appel
à James Urban, expert en foresterie urbaine, et à des
architectes-paysagistes, des arboriculteurs et des
ingénieurs pour réaliser un guide exemplaire. Celui-ci
crée un précédent en plantation d'arbres. Il relie
explicitement la santé et la longévité des arbres au
volume de terre, en plus d'offrir des choix économiques
pour fournir 20 à 30 mètres de terre à chaque arbre dans
les limites d'un trottoir urbain.

DTAH a commencé par analyser les pratiques forestières
à Toronto et dans huit municipalités nord-américaines de
climat et de densité comparables. De ces recherches, elle
a tiré les principes de base du guide et trois méthodes de
construction présentées en détail (avec spécifications pour
la collecte des eaux de pluie et les besoins horticoles). La
plantation d'arbres est intégrée aux services publics là où
l'on peut arranger la terre à l'aide de dalles de béton ou
de cellules de terreau, pour que les arbres aient assez de
place pour grandir pendant 40 ans. Le guide documente
aussi des projets pilotes qui ont testé l'accès aux services
publics, y compris les premières maquettes grandeur
réelle pour scénarios de réparation d'urgence à travers les
cellules de terreau. Le jury a recommandé la réalisation
d'une version numérique du guide pour faciliter la
circulation de ses concepts.
