For over 27 years, we’ve served the Northern California Region as civil engineers, land planners, and surveyors who design the infrastructure, drainage, and grading for residential, mixed-use, commercial projects, and public works improvements. We are creative advisors and close collaborators providing professional consulting services to private sector and public works clients from the conceptual phases of their projects through the final construction stage. We listen, deliver what we promise, and produce innovative and cost-efficient designs on time, every time. At RJA, we put people first through strong client relationships, but also with an unwavering commitment to mentorship and the growth and development of our diverse roster of talent.
