Rancho Santa Fe Road

Dokken Engineering developed preliminary engineering studies and prepared the PS&E for the realignment and widening of Rancho Santa Fe Road. The project included a federally-funded HBRR bridge replacement. Rancho Santa Fe Road was designed to accommodate 6 travel lanes, a raised median, sidewalks and parkway landscaping.

The 3-mile segment of road, constructed on new alignment in rough terrain, includes 2 new major structures over San Marcos Creek and extensive grading and earthwork. Blasting was required along the entire length of the project due to the Santiago Peak and granitic formations. Utility improvements, utility relocation, staging, detours, landscaping, and environmental mitigation of wetland impacts were important project components.

Preliminary Engineering included development of aerial mapping, alignment and profile design, drainage studies, utility relocation coordination, review of the existing geotechnical data and determination of right of way requirements. The realignment of Rancho Santa Fe Road required development of a roadway alignment and profile that met several key project objectives.

Traffic handling plans maintained free flow of bicycle and pedestrian traffic through all construction phases. Extensive grading, including rock blasting, geotechnical investigations, landscaping, surveying and drainage design were required. The final design of the project was prepared in 2 stages due to funding sources. The northern segment or Phase 2, was federally funded.
