Yes -- a 30-mile wide asteroid (or even a 10 mile wide one) would be large enough to cause global devastation, including the extinction of many
species, including humans (eventually from not just the impact, but also its aftermath).
However, A 335-foot (102 meter) asteroid is not a planet killer nor and extinction level event -- although it is still large enough to cause localized
devastation (a crater the size of a small city) and a large debris cloud that may even have a continent-wide effect.
Considering the Earth's surface is 2/3 ocean, it is more likely that it (or what's left of it after burning through the atmosphere) would strike an
ocean, causing a huge tsunami. With some warning and the calculation of an impact point, coastal areas (in the case of an ocean impact) or the
regions near a land impact could begin to be evacuated in order to save lives.
EDIT TO ADD:
...although this one will not hit us.
