See picture taken in Aloha, Oregon. Can these trees be saved?
These trees look okay. They are shedding their lower and interior needles which is normal. As long as the ends of the branches remain green, I wouldn't worry. Landscape trees do benefit from supplemental watering in mid to late summer. Water infrequently, slowly, and deeply - a soaker hose circled around the dripline area, for example, left running for a couple of hours, once every week or so.
