Monitoring

& Inspection

FOR THE HEALTH OF THE HABITAT

After initial restoration, sites require ongoing monitoring to ensure compliance with mitigation plans. We consistently track the progress and health of the site, verifying that it meets performance standards such as appropriate hydrology standards, plant growth/survivability, and invasive species thresholds. If any issues are detected, we can provide corrective actions to ensure that requirements are met. 

We offer comprehensive wetland and habitat monitoring, Stormwater Pollution Prevention Plan (SWPPP) inspections, water quality testing, and soil testing services. Our goal is to ensure environmental compliance and long-term sustainability.

CORE SERVICES

Wetland and habitat restoration monitoring
+

We provide ongoing monitoring and assessments of wetlands to track the health of ecosystems and wildlife. This allows us to detect changes and recommend adaptive management strategies to ensure long-term functionality.

We track vegetation growth, wildlife return, and ecosystem recovery to provide detailed reports and make adjustments as needed.

Stormwater Pollution Prevention Plan (SWPPP) inspections
+

Our certified inspectors conduct regular SWPPP inspections to ensure compliance with local, state, and federal regulations. We monitor stormwater management, sediment control, and erosion prevention at construction sites.

We conduct water sampling and analysis as part of SWPPP compliance, ensuring pollutants such as sediment and chemicals are managed properly.

Water quality, turbidity, and soil testing
+

We test water quality in streams, rivers, wetlands, and other bodies of water affected by development. Our tests monitor pollutants such as nutrients, heavy metals, pH, and bacteria to ensure compliance with regulations.

We conduct turbidity testing to measure the clarity of water in streams, rivers, wetlands, and other water bodies. Elevated turbidity levels can indicate sedimentation issues, pollution, or erosion. Through regular monitoring, we can detect and track changes in water quality, ensuring that the aquatic environment remains healthy and that regulatory standards are met.

We provide soil testing services to analyze nutrient content, pH, and contaminants. These tests help ensure that soil conditions are suitable for plant growth and meet all regulatory requirements.

Wetland delineation
+

Our team identifies and maps wetland boundaries to ensure compliance with local, state, and federal wetland protection regulations.

Sediment and erosion control inspections
+

We verify that erosion control measures, such as silt fences and sediment basins, are properly installed and functioning, preventing soil loss and waterway pollution. 

Cost forecasting for environmental management
+

We provide detailed cost forecasts to help plan for ongoing environmental management, monitoring, and regulatory compliance.

Permit compliance reporting
+

We assist with permit compliance by providing detailed reports on water quality, habitat health, and monitoring activities to meet the requirements of agencies like the Environmental Protection Agency (EPA), Washington Department of Ecology, Oregon Department of Environmental Quality (DEQ), and the U.S. Army Corps of Engineers.
