Whitehorse is located at kilometre 1,425 (Historic Mile 918) of the Alaska Highway and is framed by three nearby mountains: Grey Mountain to the east, Mount Sumanik to the northwest and Golden Horn Mountain to the south. The rapids which were the namesake of the city have disappeared under Miles Canyon and Schwatka Lake, formed by the construction of a hydroelectricity dam in 1958. Whitehorse is currently the 64th largest city in Canada by area. The city limits present a near rectangular shape orientated in a NW-SE direction.
Whitehorse Bylaw 426 (1975) restricts the operation of motor vehicles to designated roadways in certain "Protected Areas" to ensure maximum conservation of the environmental quality. Most are near the downtown core (downtown and Yukon river escarpments, Mt. Mac ski trails, Riverdale, Valleyview, Hillcrest, Granger, Porter Creek, and Mountainview) and one, Pineridge, is south of downtown.
In 1999, the city approved the Area Development Scheme (ADS) which reallocated the area previously known as "Whitehorse Copper" to the following uses: Country Residential, Commercial, Service Industrial, and Heavy industrial.
Recent demands for growth have reignited urban planning debates in Whitehorse. In 1970 the Metropolitan Whitehorse development plan included park and greenbelt areas that were to be preserved to ensure high quality of life even within city limits.
