Other Services
Environmental Services
Wilson Construction Company’s environmental division specializes in environmental compliance management as it relates directly to the utility construction industry. Our team brings expertise to construction projects in the areas of mitigation planning; permitting; Storm Water Pollution Prevention Plan (SWPPP) development and implementation, inspection and monitoring; erosion and sediment control; and restoration and environmental training.
Wilson Construction works proactively toward ensuring successful work operations with minimal impact on the environment. By making sure our workforce is conscious of the environmental issues on every job we perform, and by stressing minimal disturbance as part of our work policy, projects are completed successfully with as little disturbance as possible. Our environmental planning starts as early as the bid process ensuring that the environment is considered in how we will perform the work.
Our Capabilities Include:
Environmental Mitigation Planning and Implementation
Many projects have some element of environmental mitigation that is required. We can help you develop a mitigation implementation plan that details how to protect the resources on your project during construction. Our team has experience dealing with a wide variety of environmental issues, including but not limited to, protected animal and plant species and their habitat, aquatic resources, including wetlands and vernal pools, and cultural resources.
Environmental Compliance Management and Inspection
- Oversight of project environmental requirements
- Inspection, monitoring and reporting of implementation of Best Management Practices
- Technical review of pre-construction documents (i.e. permits, technical specifications, etc.)
Erosion and Sediment Control
Construction projects have the potential to expose large areas of soil which increase the risk for soil erosion and sediment-laden storm water run-off. Wilson Construction can develop and/or implement a Storm Water Pollution Prevention Plan for you. Our team will design, install and maintain your temporary and permanent erosion and sediment control Best Management Practices (BMP's) throughout the construction of your project.
Environmental Training
Wilson Construction Company will develop a training program specific to your project and train your personnel. Possible training topics include:
- Spill response
- Best Management Practice (BMP) installation
- Environmental protocols
- Cultural resource protection
- Noxious weed management
Restoration Planning and Implementation
Wilson Construction Company offers complete restoration services that include reclamation and revegetation.
Projects Examples
Ebey Slough Transmission Line Rebuild Project, Everett, WA
This project involves removing and rebuilding a 2-mile portion of two single-circuit transmission lines to double-circuit. The existing lines are in a tidally-influenced, partially-inundated wetland and will be rebuilt within the existing ROW. Specialized equipment is being used to construct micropile foundations and move materials from site to site within the wetlands. Multiple permits were obtained to work in wetlands; daily monitoring and inspections are being performed to monitor turbidity and dissolved oxygen. Wilson developed a Storm Water Pollution Prevention Plan (SWPPP) for the project and is responsible for implementation. Erosion and sediment controls were installed in the wetland to contain turbid water and keep discharges from occurring. Construction operations (i.e. micropile drilling, grouting, concrete operations, tower erection & pulling wire) have been carefully planned to keep impacts to wetlands minimized. Tower removal will occur once the new structures are in place and restoration to wetlands will begin immediately.
Starkey-McCall Line Rebuild, McCall, ID
This project entails rebuilding sections of transmission line through varied terrain in Idaho. The line travels across Forest Service and private lands and has several different federal and state permits that required careful monitoring and inspection duties. Work is being conducted in wetlands and roads cross streams to access tower sites. A Storm Water Pollution Prevention Plan (SWPPP) was developed and is being implemented by Wilson for the duration of the project. Mitigation was developed for cultural resources to reduce the impacts and wash stations have been developed to reduce noxious weeds spreading. All sites need to be restored, half due to Forest Service requirements.
Restoration - Teton Pass Structure Modification, Teton Pass, Wyoming
This project involved modifying the tops of several towers, rebuilding a new tower and restringing wire. Successful restoration at such high elevations, where the topsoil layer is thin and fragile, takes careful planning of work by crews. Topsoil was saved during excavation and at project end, slopes were jute matted and a mix of native grass seed, compost, and mulch were spread for winter stabilization with successful germination and growth after one year.

SWPPP Implementation - Mission-Miguel 230-kV Line Rebuild, San Diego, California
This project was located in mountainous terrain and through urban environments. With a lot of exposed soil from building work pads to installing new towers, erosion and sediment control was a major issue during winter months. Wilson was responsible for successful SWPPP implementation which included designing, installing and monitoring BMPs throughout the project life to maintain compliance with the SWPPP.
SWPPP Implementation – Atlantic-Del Mar 115-kV Underground Project, California
This project involved installing approximately one mile of underground duct and line. Horizontal drilling took place through a wetland (and under an overpass) and trenching occurred across a stream. Wilson installed and monitored BMPs throughout the project.
