Environmental Site Assessments & Transactional Due Diligence
Defensible, high-stakes environmental risk assessments for commercial lenders, real estate developers, institutional investors, and municipal agencies. From ASTM-compliant Phase I/II ESAs and SBA risk screens to complex subsurface characterization, cost-to-cure analysis, and regulatory closure across California and Arizona.
Core Assessment Practices
Phase I ESAs (Environmental Site Assessments)
Non-invasive historical property investigations designed to identify Recognized Environmental Conditions (RECs), Controlled RECs (CRECs), and Historical RECs (HRECs). Essential for securing CERCLA Innocent Landowner Liability Defense prior to acquisition or foreclosure.
- EPA All Appropriate Inquiries (AAI) Compliant
- Historical Aerials, Sanborn Maps & City Directories
- Regulatory Database & Environmental Lien Sweeps
Phase II ESAs & Subsurface Investigations
Targeted intrusive sampling to confirm or rule out contamination when RECs are identified. We provide clear, quantified analytical data to determine the lateral and vertical extent of environmental impact, assessing financial liability prior to closing.
- Soil Matrix & Groundwater Monitoring Wells
- Heavy Metals, TPH, Solvents & PFAS Testing
- Geophysical Surveys (GPR) for Underground Tanks
Environmental Report Peer Reviews
Independent 3rd-party technical reviews of existing Phase I/II reports completed by other firms. We protect institutional lenders, buyers, and capital partners from flawed methodology, missed RECs, or overly aggressive (and expensive) remediation recommendations.
- Secondary Review of 3rd-Party Phase I/II Reports
- REC Liability & Cost-to-Cure Quantification
- Fast-Track Audits for Escrow Closing Deadlines
UST & Vapor Encroachment Audits
Specialized due diligence for high-risk properties including automotive repair shops, gas stations, dry cleaners, and legacy industrial sites. We evaluate subsurface migration risks that threaten indoor air quality and groundwater.
- ASTM E2600 Vapor Encroachment Screening
- PCE/TCE Solvent & Benzene Migration Studies
- Underground Storage Tank (UST) Leak Assessments
Municipal & Grant-Funded Assessments
Environmental due diligence tailored for municipal land acquisitions, public infrastructure projects, and federal/state grant-funded capital developments. Assuring compliance with funding mandates and multi-agency oversight frameworks.
- NEPA / CEQA Environmental Support
- Public Waterfront & Habitat Land Assessments
- Grant Compliance & Multi-Agency Liaison
Developer Risk & Soil Management
Translating discovered environmental contamination into actionable development plans. We support developers transforming brownfields, agricultural land, or industrial sites into multi-family or commercial assets.
- Soil Management Plans (SMP) for Grading & Excavation
- Agricultural Chemical & Pesticide Residue Profiling
- Regulatory Agency "No Further Action" (NFA) Support
Specialized Due Diligence Pathways
For Commercial Lenders & Banks
We provide tiered risk assessments tailored to specific loan products, collateral risk tolerances, and federal underwriting guidelines, ensuring seamless loan approvals.
SBA SOP 50 10 7 Compliance
Full compliance with the Small Business Administration’s rigid environmental guidelines for 7(a) and 504 loans, ensuring loans are not delayed by environmental rejections.
RSRAs (Records Search with Risk Assessment)
A cost-effective, SBA-approved desktop review combining historical regulatory database searches with a professional risk determination for low-risk commercial properties.
Transaction Screen Assessments (TSA)
Conducted under ASTM E1528, a TSA serves as a middle-tier assessment utilizing a limited environmental questionnaire and site visit, ideal for properties where a full Phase I ESA is deemed excessive by the lender.
Fannie Mae / Freddie Mac / HUD
Customized Phase I ESA reporting formats to meet the specific requirements of agency lenders for multi-family, affordable housing, and healthcare facility financing.
For Real Estate Developers & Investors
For developers, a REC is not just a liability flag—it’s a threat to the project budget and timeline. We provide the data required to quantify the risk, negotiate the purchase price, and build safely.
Cost-to-Cure & Liability Quantification
If contamination is discovered, we perform delineated Phase II testing to estimate the financial cost of remediation or mitigation, giving developers leverage during purchase price reductions or escrow holdbacks.
Brownfield & Rezoning Support
Environmental risk profiling for properties transitioning from high-hazard industrial/agricultural uses to sensitive residential or mixed-use developments, ensuring compliance with local health departments.
Vapor Encroachment & Mitigation
If off-site contamination threatens your parcel, we conduct ASTM E2600 vapor encroachment screening and consult on the design of sub-slab depressurization systems or vapor barriers.
Soil & Groundwater Management Plans
Providing clear, legally defensible protocols for general contractors handling, exporting, or disposing of impacted soils during grading and trenching operations.
The Phase I ESA Methodology
Our Phase I Environmental Site Assessments are exhaustive. Following the EPA All Appropriate Inquiries (AAI) rule and ASTM E1527-21, every assessment is built on four critical pillars of investigation:
1. Historical Review
Tracing property use back to its first developed use (or 1940) utilizing historical aerial photographs, Sanborn Fire Insurance maps, historical city directories, and topographic maps to identify legacy industrial or agricultural risks.
2. Regulatory Search
Comprehensive radius sweeps of federal, state, tribal, and local environmental databases (NPL, CERCLIS, RCRA, LUST) to identify spills, permitted hazardous waste generators, or institutional controls on or adjacent to the target property.
3. Site Reconnaissance
A thorough physical inspection of the target property and visual assessment of adjoining properties by an environmental professional, searching for underground storage tanks (USTs), chemical storage, stained soils, or stressed vegetation.
4. Interviews & Reporting
Interviews with current/past owners, site managers, and local government officials (fire/health departments). Culminating in a defensible, executive-level report clearly declaring the presence or absence of RECs.
