Engineer of work for an approximate 1.2-mile extension of a major super-elevated roadway connecting an existing terminus at the Santee City limits to the intersection of Riverford Road and Riverside Drive. The project corridor, adjacent to the floodplain limits of the San Diego River, is unimproved, and the completion of this segment of roadway will connect a key link in the regional transportation plan. 82 feet of roadbed with bike lanes and 102 feet of right-of-way was proposed for the ultimate roadway configuration. The plans prepared provided for an interim paved width of 42 feet.

A new traffic signal at the intersection of Riverford Road and Riverside Drive was designed to accommodate the interim and ultimate roadway configurations to minimize traffic signal modifications in the future. Drainage systems within the public right-of-way were located in their ultimate roadway locations and modified to provide drainage for interim conditions. The new roadway''s close proximity to the San Diego River resulted in the need for one major drainage facility. This facility, consisting of a double 12'' x 4'' RCB, riprap and grass-lined channels which provides drainage for a 400-acre basin with a discharge of 600 cfs. Roadway striping, signing, traffic control, detouring, specifications and detailed construction cost estimates were also provided.

A separate set of right-of-way dedication drawings were prepared for the acquisition of 77 separate parcels involving 23 individual land owners. The parcels were for road right of way, slope and drainage easements, and temporary construction easements. Research of record maps, deeds and right-of-way dedications was necessary for the calculation of new parcels, areas and final deed writing for easements and acquisitions. This project involved extensive coordination with the County of San Diego Real Property Department and their title company, and the City of Santee for all facets of design. A value engineering review was conducted at the 30% review stage. Recommendations from the review were incorporated into the design.
