Environmental Assessment Maryland | Phase I & Phase II ESA Commercial Properties
Environmental assessment is the non-negotiable due diligence step in every Maryland commercial real estate acquisition and development project. Maryland’s industrial legacy, the Baltimore steel mills of Sparrows Point, manufacturing corridors of Baltimore City and County, petrochemical facilities along the Patapsco, and former military installations across the state has left an environmental footprint affecting thousands of commercial properties. Acquiring a Maryland commercial property with unidentified environmental contamination is not an investment risk, it is a potential regulatory and financial catastrophe.
Fortune Homes MD coordinates Phase I and Phase II Environmental Site Assessments for Maryland commercial development projects, working with ASTM-certified environmental professionals to identify recognized environmental conditions before acquisition and to characterize contamination when Phase I findings require further investigation.
Phase I Environmental Site Assessment Maryland Standards
A Phase I ESA conducted under ASTM Standard E1527-21 is the industry-standard initial environmental assessment for Maryland commercial properties. Phase I ESAs identify Recognized Environmental Conditions (RECs) evidence of hazardous substances or petroleum products that may have been released at, onto, or from the property. Every Maryland commercial mortgage lender requires a Phase I ESA.
Phase I Component | What It Reviews | Maryland-Specific Considerations |
Records Review | Federal/state environmental databases; historical maps; aerial photos; city directories | MDE MILES database for Maryland UST and remediation sites; DNR wetlands mapping |
Site Reconnaissance | Physical inspection of subject and adjoining properties; drainage patterns | Observe for stressed vegetation, soil staining, drums, pipelines, dry wells |
Interviews | Current and former owners, occupants, key site managers | Former industrial tenants in Baltimore City often unknown |
Historical Research | Sanborn fire insurance maps; first-developed-use research | Baltimore City manufacturing districts 1880–1960 require extensive Sanborn research |
Report and Conclusions | RECs, Controlled RECs (CRECs), Historical RECs (HRECs), de minimis conditions | Maryland BRAC brownfields may have CRECs from prior remediation |

Phase II ESA When and What
- When Phase II is Required: Phase II ESA is appropriate when Phase I identifies prior use as gas station, dry cleaner, auto repair, or industrial manufacturing; evidence of former underground storage tanks; documented spill or release history in MDE’s regulatory database; hydraulic fill or fill material of unknown origin; or vapor intrusion concern from an adjacent contaminated property.
- Phase II Sampling Protocol: Includes soil borings at suspect areas; soil samples submitted to AIHA-certified laboratory for VOCs, SVOCs, metals, and petroleum hydrocarbons; groundwater monitoring wells if soil results indicate potential groundwater impact; and indoor air sampling for vapor intrusion assessment if chlorinated solvents or petroleum hydrocarbons are detected in shallow soil.
- Phase II Cost and Timeline: Maryland Phase II ESA costs $8,000 to $75,000+ depending on the number of borings, analytical scope, and property size. A targeted Phase II at a former gas station costs $15,000 to $30,000. A comprehensive Phase II at a former industrial site in Baltimore City costs $40,000 to $100,000+. Timeline: 4 to 8 weeks from mobilization to final report.
- MDE Voluntary Cleanup Program (VCP): For Maryland properties with confirmed contamination, the VCP provides a structured pathway to regulatory closure allowing owners to remediate in exchange for a Certificate of Completion (COC) limiting future liability. Maryland also provides brownfields tax credits of up to 25% of eligible cleanup costs for qualified VCP participants.
Maryland Environmental Risk by Property Type
Property Type / Prior Use | Environmental Risk | Typical Phase I Findings | Phase II Trigger Likelihood |
Former Gas Station | Very High | UST-related petroleum contamination | Very High almost always triggered |
Former Dry Cleaner | Very High | Chlorinated solvent (PCE/TCE) contamination | Very High PCE migrates extensively |
Former Auto Repair / Body Shop | High | Petroleum, metals, solvents | High floor drain discharge areas |
Former Industrial (manufacturing) | High | Varied metals, solvents, petroleum, process chemicals | High dependent on prior process |
Former Military / Government (BRAC) | High-Very High | Chlorinated solvents, petroleum, metals, munitions | High MDE/DoD coordination required |
Vacant Suburban Land (no prior development) | Low | Agricultural chemicals (if farmed) | Low if no fill material of concern |
Office / Retail (no prior industrial) | Low-Moderate | Minimal unless former gas station vicinity | Low if no RECs identified in Phase I |
Baltimore City Rowhouse / Commercial Block | Moderate-High | Fill material, lead soil, former industrial uses | Moderate historical research critical |

Maryland Environmental Regulations Affecting Commercial Development
- MDE NPDES Construction Stormwater Permit: Required for all land disturbance over 1 acre. Must develop and implement a Stormwater Pollution Prevention Plan (SWPPP) with Erosion and Sediment Control (E&S) measures. Violations result in fines of $1,000 per day per violation.
- MDE Tidal and Nontidal Wetlands: Any project disturbing wetlands in Maryland requires a wetlands permit from MDE Water Management Administration. Wetlands mitigation at 2:1 to 4:1 ratio is required for unavoidable impacts. Wetlands delineation in the field is mandatory before site plan submission on any site with potential wetland areas.
- FEMA Floodplain: Commercial development within FEMA 100-year floodplain (Zone AE) requires a Floodplain Development Permit and elevating the building’s lowest floor at least 1 foot above the Base Flood Elevation. Maryland county ordinances may impose more stringent requirements.
- Maryland Asbestos Control Program: Demolition and renovation of commercial buildings built before 1980 requires an asbestos survey by an MDSPN-certified inspector. Friable asbestos-containing materials must be abated by a licensed Maryland contractor before construction begins. Abatement costs $5 to $35 PSF depending on ACM type and quantity.
Frequently Asked Questions Environmental Assessment Maryland
A: A Phase I ESA for a Maryland commercial property costs $2,500 to $6,000 for standard commercial sites. Properties with complex historical use patterns, former industrial sites in Baltimore City, multi-tenant buildings with multiple prior occupancies cost $4,500 to $8,500. Phase I is typically delivered in 10 to 15 business days. This cost is a fraction of potential remediation exposure. A Phase I identifying a former dry cleaner saves potentially $200,000 to $1,000,000 in post-acquisition remediation liability.
A: While not legally mandated by Maryland law, a Phase I ESA is functionally required for three reasons: virtually all commercial mortgage lenders require it under ASTM E1527-21 as a loan condition; it is the primary tool for establishing the Innocent Landowner Defense under CERCLA; and Maryland MDE can hold current property owners liable for contamination regardless of when it occurred. Fortune Homes MD recommends a Phase I ESA for every Maryland commercial acquisition without exception.
A: Maryland’s VCP provides a regulatory pathway for cleaning up contaminated properties and obtaining a Certificate of Completion (COC) that limits future environmental liability. For developers, the VCP allows brownfield redevelopment on formerly contaminated sites converting liabilities into assets with MDE oversight and a clear regulatory endpoint. Maryland brownfields tax credits of up to 25% of eligible cleanup costs make brownfield redevelopment financially viable in many Baltimore City and Baltimore County locations.
