Your grades are excellent, and from the few posts of yours that I've read on this forum, you seem intelligent and devoted and will deliver a compelling personal statement. With good SAT scores, you should definitely be illegible for scholarships and financial aid.
UC Riverside sounds like a great choice, and your credentials make you more than a qualified applicant, but don't put all your eggs in one basket. Remember, the more schools you apply to, the greater chance one of them will present you with a scholarship or financial aid package. Just like the others have said, talk to your councilor and research a variety of viable schools with good engineering programs and cost-saving opportunities.
Best of luck to you.
