Alaska
Phase I Environmental Site Assessment
ASTM E1527-21 Phase I ESA to identify contamination risk before buying or financing commercial property.
What the work involves
A Phase I ESA reviews historical records, regulatory databases, site reconnaissance and interviews to identify recognized environmental conditions. Performed to ASTM E1527-21 and EPA's All Appropriate Inquiries rule, it helps buyers qualify for CERCLA liability protections and is commonly required by commercial lenders. It is performed by an environmental professional, who may or may not be a civil engineer.
Local conditions we plan for
- Permafrost and thaw settlement
- High seismic hazard (2018 Anchorage M7.1 earthquake)
- Coastal and riverbank erosion threatening villages
- Deep seasonal frost and short construction seasons
Building code: 2021 IBC adopted at the state level; no statewide IRC (residential codes adopted locally) (ICC adoption chart, April 2026).
When you need it
- Buying commercial or industrial property
- Lender requires a Phase I
- Former gas station, dry cleaner or industrial use
- Redevelopment of a brownfield
Frequently asked questions
How much does phase I Environmental Site Assessment cost?
Across the US, phase I Environmental Site Assessment usually costs $1,500 to $5,000 per site. Estimate from consultant and cost-guide sources, which commonly report about $1,500 to $5,000 for typical sites and more for large or complex ones.
How long does phase I Environmental Site Assessment take?
Plan on 2 to 4 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for phase I Environmental Site Assessment?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Alaska?
Engineers practicing in Alaska are licensed by the State Board of Registration for Architects, Engineers, and Land Surveyors (AELS). You can confirm a license number and its status in the board's public license search before you sign a contract.
Which building code applies in Alaska?
2021 IBC adopted at the state level; no statewide IRC (residential codes adopted locally) (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
What site problems do engineers see most in Alaska?
Common issues include permafrost and thaw settlement, high seismic hazard (2018 Anchorage M7.1 earthquake), coastal and riverbank erosion threatening villages and deep seasonal frost and short construction seasons.
