Reconstructing an Abandoned Scenic Roadway for Multi-Use Recreation

In improving the roadway as a multi-use trail, the project included slope and road embankment stabilization (including landslide repair), pavement repairs, reconstruction and overlay, and repair or enhancement of existing drainage infrastructure. As a subconsultant to the Project Engineers, LSA identified potential constraints related to biological and cultural resources so engineers could incorporate impact avoidance and minimization measures into the design. As a federally funded project, LSA prepared technical reports to document compliance under the National Environmental Policy Act (NEPA) and Caltrans Local Assistance Procedures including a Natural Environment Study (NES), Biological Assessment (BA), a Traffic/Noise Technical Memorandum, a Water Quality Assessment, a Visual Technical Memorandum, Archaeological Survey Report (ASR), Historical Resources Evaluation Report (HRER) and Historic Property Survey Report (HPSR). LSA prepared required regulatory permits (CDFW, RWQCB) on behalf of EBRPD and performed construction monitoring for both biological and cultural resources to ensure compliance with all permit conditions. Construction started in June 2013 and the trail opened for public use in November 2014. LSA is conducting ongoing monitoring of the revegetated areas and submitting annual reports to the Regional Water Quality Control Board for the next 5 years.
