Chapter 7
Three factors to address within the LT Category
Neighbourhood pattern and design
Three factors of location
Natural context – Mother Nature
Infrastructural context – utilities and roadway access
Social context – historic value of site, local regulations including zoning, and connection to the community
Floor-to-area ratio
The proportion of total floor area of a building to the total land area the building can occupy
Six strategies to address when selecting a site
Increase density
Choose redevelopment
Locate near existing infrastructure
Protect habitat
Increase diversity of uses
Encourage multiple modes of transportation
Real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant
Four impacts of transportation
Land use – length and frequency of trips
Vehicle technology – quantity and types of energy and support systems needed to move people and goods to and from the site
Fuel – environmental impact of vehicle operation
Human behaviour – a daily transportation decision combining the listed impacts
Three strategies to address transportation during design and planning
Choose a site adjacent to mass transit
Limit parking capacity
Encourage bicycling
Four strategies to address transportation during operations and maintenance
Encourage carpooling
Encourage or provide alternative fuel vehicles
Incentivize building users/employees
Support alternative transportation
Pedestrian infrastructure includes
Sidewalks, crosswalks, all weather surface footpaths or equivalent pedestrian facilities
Bicycle infrastructure includes
On-street bike lanes, off-street bike paths and trails, and streets with low vehicle speed limits
