At Hao Engineering Group, we view civil engineering as a means to enhance everyday living through thoughtful site development and infrastructure design. Regardless of project scale, our goal is to deliver solutions that are functional, cost-effective, code-compliant, and environmentally responsible, while contributing long-term value to the property and the communities it serves.

We specialize in supporting owner-users, developers, and builders through all phases of residential and commercial land development — from early site planning, grading and utility design to permitting and construction administration.

We’re particularly drawn to projects that present complex site conditions or regulatory challenges, and we pride ourselves on developing creative, practical solutions that keep projects moving forward with confidence.

Led by licensed civil engineers with average 12+ years of experience in grading, drainage, stormwater management, utilities, and permitting, our firm brings together deep technical expertise and strong knowledge of California’s regulatory. We collaborate closely with design teams, architects, surveyors, and contractors to ensure the engineering is not just compliant — but constructible, efficient, and aligned with the broader design intent.
