Engineering sustainable solutions for tomorrow’s world.  

SWCA has a highly qualified team of engineers, landscape architects, scientists, planners, and cultural and natural resources experts that blend science with innovation to restore ecosystems. SWCA Environmental Consulting and Engineering, an affiliate of SWCA, specializes in ecological restoration engineering and water quality remediation of the physical and biological environment, working in systems such as streams, wetlands, and coastal shorelines to improve water quality and support a diverse aquatic community. The engineering team also provides civil site development services for the solar industry including preliminary civil construction layouts, drainage plans, pre- and post-construction stormwater management, floodplain engineering, and final construction plans.

Specialties

Stream and Ecological Restoration

SWCA has a dedicated ecological restoration and engineering team that designs, permits, and restores impaired ecosystems every day. This team specializes in stream restoration, wetland restoration, and living shoreline projects, and have successfully implemented these projects in numerous physiographic settings across the country, including the mountain, piedmont, prairie, coastal and central plains, and estuarine provinces.

Site Civil Design

SWCA’s team of engineers and drafters develops 30/60/90% and Issue for Construction Drawing Sets. The engineering team works directly with the environmental and cultural resource teams to ensure the proper setbacks are maintained. SWCA generates a grading plan that utilizes information from developers and geotechnical engineers including maximum slopes and maximum depths of cut. The hydrology study results are used to determine if stormwater management controls are necessary and then the team will design them in locations that will maximize the buildable layout.

Erosion and Sediment Control Plans (E&SC Plans)

SWCA generates E&SC Plans utilizing the grading plan and stormwater management controls to recommend locations for Best Management Practices (BMPs) to control sediment laden runoff from leaving the project area. The E&SC Plan incorporates soil information, construction notes and details, construction sequencing and site restoration recommendations. 

Spill Prevention, Control and Countermeasure (SPCC) Plans

SWCA understands the critical importance of mitigating the risks associated with oil spills for both our clients and the environment.  SWCA develops SPCC Plans to meet the regulatory requirements of the EPA and works with the developer to generate site specific SPCC Plans.  After a plan is generated our team provides training programs to educate staff and ongoing support as the facility changes over time.

Hydrology Studies and Hydraulic Modeling

SWCA models the existing project area and determines the impacts by the project development using hydrology programs such as Hydraflow, HydroCAD, HEC-RAS, and HEC-HMS. The team works with local and/or state regulations to determine the proper modeling criteria for the project and then models the results to determine possible locations and sizes of stormwater management controls.
