Cardno’s assistance on the project includes riparian ecosystem, fluvial geomorphology, and restoration design engineering expertise. Staff are performing detailed site inventories and mapping of stream channels, streambanks, and riparian vegetation conditions throughout the project area. These data supplement general assessments with a focus on developing reach- and site-scale restoration strategies for the Merced River within the Yosemite Valley.
Cardno prepared conceptual treatment plans and prioritized additional data needs for design, implementation costs/risks, and expected individual and synergistic benefits. The restoration design emphasis is on treatments with small footprints and advance natural processes. Cardno designed and provided construction oversight for restoring geomorphic and riparian function of several sites along the Merced River between 2016 and 2018. Treatments have included the use of local large wood resources, riparian plantings, and the removal of unnecessary artificial materials.
Additional services included the coordination of public outreach, hydraulic modeling, geologic mapping, riparian corridor assessment, and environmental compliance. Cardno continues working closely with NPS staff to provide efficient field survey, design development, and construction oversight services.
Cardno is assisting the National Park Service with scientific and technical services in a decade-long project to restore a significant and historic area filled with natural resources.
