Case Studies: Real Projects, Real Results
Urban Brownfield to Mixed-Use Development
Real Estate Development
Challenge:
Former industrial site with soil and groundwater contamination. Developer needed cleanup and regulatory closure to proceed with $65M residential/retail project.
Solution:
Phase II assessment, remedial action plan, soil excavation oversight, institutional controls, voluntary cleanup program enrollment, and regulatory closure.
Result:
Site achieved regulatory closure in 18 months. Development proceeded on schedule. Property value increased from $2M to $65M.
Manufacturing Facility Air Quality Compliance
Manufacturing
Challenge:
Manufacturer received EPA Notice of Violation for air emissions exceedances and incomplete Title V permit. Facing $250K+ in fines.
Solution:
Emissions inventory, compliance evaluation, permit modification application, pollution control equipment upgrades, and settlement negotiation.
Result:
Fines reduced to $45K. Achieved full compliance. New permit approved in 6 months. Ongoing compliance costs reduced 30%.
Tech Campus Carbon Neutrality Program
Technology
Challenge:
Fortune 500 tech company committed to carbon neutrality by 2025 but lacked strategy and baseline data. 4-building campus, 850K sq ft.
Solution:
GHG inventory (Scopes 1, 2, 3), energy audits, renewable energy feasibility, offset strategy, efficiency roadmap, and tracking dashboard.
Result:
Achieved carbon neutrality 2 years early (2023). $1.8M annual energy savings. LEED Platinum for all buildings. Enhanced ESG ratings.
Coastal Infrastructure Climate Adaptation
