The OP may be able to get the GPA above 3.0, but not high enough to get admitted to the chemical engineering major at Washington.
Also, while having a <3.0 GPA can be a significant limitation on finding a job at graduation, it does not necessarily mean that one will be completely unable to find one (but one cannot be picky, and if there is an economic or industry downturn when one graduates, the <3.0 GPA graduates will probably be hurt worse).
