Rachael was the project manager for the creek relocation and restoration design. The $2 million project includes 2,000 lineal feet of creek realignment and replanting. The restoration and floodplain wetlands will fully mitigate for the regulatory impacts of several culvert extension projects. Rachael was responsible for all day-to-day design management activities, including coordinating with the client, design team, local agencies and external stakeholders. She was also responsible for financial management, scheduling and the overall monitoring of the project to ensure compliance with the client’s needs and project goals.

The VTA’s Freight Railroad Relocation Program included both the Contract C210 Berryessa Creek Crossing, Abel Street Seismic Retrofit, and UPRR Railroad Relocation Project and the Contract C211 Wrigley Creek Improvement Project.  The Berryessa Creek crossing and the mitigation at Wrigley Creek are directly relevant to the SCVWD’s Lower Berryessa Creek work.

The $15.2 million FRR & Berryessa Creek Improvement project included the construction of three roadway grade separations, BART and UPRR bridges, and construction of a 5-cell box culvert for Berryessa Creek and upgrades to 6 other creek crossings at on Scott Creek, Calera Creek, Line B, Line B-1, and Wrigley Creeks as part of VTA’s Freight Railroad Relocation/Lower Berryessa Creek Project. Directly relevant project elements include:

  • Demolition and replacement of the Berryessa Creek culvert with a 5-cell box culvert and associated grading for the SCVWD Lower Berryessa Creek Flood Control Improvements in advance of the main project works
  • Replacement of the existing pipe culverts at the Line “B” channel and Wrigley Creek with box culverts.
  • Construction of pier protection walls at Abel Street Overhead and Calaveras Boulevard Overhead.
  • Demolition and replacement of the railroad crossings at Scott Creek with a box culvert.
  • Creek diversions as necessary for the construction
  • Earthwork/embankment from south of the Line “B” channel to north of Montague Expressway.
  • Relocating utilities within sensitive creek habitats and watersheds

The $1 Million Wrigley Creek Improvements project included construction of a creek restoration site to fully mitigate for biological and wetland impacts by restoring and enhancing an 1,580 LF, 5.6 acre portion of Wrigley Creek.  Directly relevant project elements include:

  • Removing accumulated sediment within a 360 LF enclosed culvert
  • Realigning the existing man-made trapezoidal channel and creating a natural channel with meanders 345 LF longer than the original channel
  • Creating a new floodplain with a 1-acre seasonal wetland
  • Enhancing the hydrologic and geomorphic functions of the creek such as sediment transport and deposition, natural water quality improvement, flood storage, and fish and wildlife habitats
  • Removal of nonnative and invasive plant species and replacement with native vegetation, including Congdon’s tarplant, a special status plant species
