Environmental Site Assessments
Our Phase I and II Environmental Site Assessments identify potential contamination through comprehensive property history reviews and subsurface investigations. We employ licensed professionals to conduct soil and groundwater sampling, vapor intrusion assessments, and regulatory compliance checks. Clients receive detailed reports that meet ASTM standards and support real estate transactions, development projects, and environmental remediation planning.
Geotechnical Engineering
We provide subsurface explorations and foundation design recommendations for commercial and residential developments. Our services include critical areas evaluation, erosion control planning, and construction monitoring for structural fill placement. Licensed engineers deliver site-specific reports that address soil stability, bearing capacity, and seismic considerations to ensure safe and code-compliant construction.
Hydrogeology Services
Our hydrogeologists specialize in groundwater assessment and stormwater management solutions. We conduct infiltration testing, dewatering analysis, and aquifer hydraulic testing to support sustainable development. Services include monitoring well installation, groundwater sampling, and low-impact development feasibility studies that help clients meet municipal stormwater regulations and environmental protection requirements.
Environmental Remediation
We implement remedial solutions for contaminated properties through the Washington State Department of Ecology's Voluntary Cleanup Program. Our services include soil vapor extraction, in-situ chemical treatment, and underground storage tank decommissioning. We provide litigation support and cost recovery analysis while maintaining strict safety protocols during hazardous material handling and site restoration.
Regulatory Compliance
Our team navigates environmental regulations for clients seeking project approvals. We prepare critical areas reports, erosion control plans, and best management practice recommendations that satisfy local jurisdiction requirements. With extensive experience in municipal permitting processes, we facilitate smooth project entitlements while ensuring compliance with state and federal environmental protection standards.
