Who this is for.
Consultants scoping site assessments, and the lenders and buyers who commission them.
The scoping call is where a site assessment gets priced, and it is usually made from whatever the regulator search page returned that morning.
What the scoping call needs.
- Which regulated facilities sit on or near this site, and what is their enforcement history?
- What releases have been reported in this county, and when?
- Which public drinking water systems serve this area, and what have they been cited for?
- Is the site on a land reuse or brownfields record, and what does that record say?
What answers those questions.
Nobody maintains this roster by hand. Each block claims a kind of source, the directory fills it at build time, and a source connected next month appears here on the build after that.

Catalogued for this role, not live.
ParcelOps has these in the directory for this kind of work and has not connected them, so they answer nothing today and no link goes to them. Naming them is the point of a page like this: FCC Broadband Availability, Spain Cadastre INSPIRE, France Cadastre, UK Land Registry INSPIRE.
What this does not cover.
The paragraph a directory of sources will not write, and the one worth reading before an answer goes into a decision someone else pays for.
- This is not a site assessment and meets no standard for one. It is the scoping pass before the standard applies.
- A radius search describes a point. A large parcel can carry a condition well away from the coordinate that was queried.
- Historical aerials, fire insurance maps, city directories, and title chains are absent, and a real history search spends most of its time in exactly those.
- Federal databases lag their own reporting, so an absent record is not evidence that nothing happened.
- State and local records vary enormously in what they publish. A clean federal screen can sit on top of a state file nobody has read.
How to read these records.
Each of these gets quoted wrongly often enough to be worth stating in place.
- A reported release
- The national hotline record is what a caller reported at the time, unverified. It establishes that a call was made, not that a release occurred or how large it was.
- A drinking water citation
- The federal water record is organized by public water system rather than by tap. A violation belongs to the system serving an area and says nothing about a specific building or fixture.
- A facility listed nearby
- The federal enforcement and facility files are organized around regulated facilities. A listing next door means there is a history to read, not that there is contamination on your site.
- A mapped wetland
- The national mapping is built from imagery and soils at a screening scale. Jurisdiction is decided by a delineation and by the agency, not by the map.
Questions consultants ask.
Does this satisfy the standard for a Phase I?
No, and it does not try to. The standard governs who performs the work, what sources are consulted, how the site reconnaissance and interviews are conducted, and how the findings are written. This is the database pass that happens before any of that, useful for scoping and pricing rather than for the deliverable.
How far around a site do the searches reach?
It depends on the record. Some federal files are organized by facility coordinate and support a radius, some are published by county and answer only at that grain, and some are point layers that answer where you ask. Every answer names its source, so the grain of the answer is visible rather than flattened into one number.
Why is a county level release record still useful?
Because it tells you what kind of releases get reported in an area and how often, which is context a site specific search does not give you. Read it as an initial report by a caller, not as a verified event, and use it to decide what the site specific work needs to cover.
