Phase 1 ESA Checklist: What to Expect and What You’ll Receive

Most people order their first Phase 1 Environmental Site Assessment because a lender put it on a closing list, and the inspection period is already running. That’s a stressful way to buy anything, and there’s no reason you’d know in advance what the process asks of you. This page is the checklist we’d hand you on the first call: what to have ready, what happens over the next two weeks, and what you’ll be holding at the end.

If you’re still working out whether you need one at all, start with when a Phase 1 is actually required. If you want the full process explained first, our Southwest Florida guide to Phase 1 assessments covers it. This one assumes you’ve decided and want to get it done.

Before We Start: What to Have Ready

Here’s the part of the timeline you control. Every item below is something the environmental professional will otherwise have to chase, and chasing is where a two-week job turns into four.

1. The parcel numbers and legal description. Every parcel ID in the deal, not just the main one. Each separate parcel number is its own research file, so an assemblage of three lots is three sets of records, not one.
2. A survey, plat, or site plan if you have one. It doesn’t need to be current or stamped. We’re using it to know where the property lines are when we walk it.
3. Who can let us on the property. A name and phone number for the seller, the tenant, or whoever holds the gate key. On gated, fenced, or occupied sites, access is usually the single biggest scheduling variable in the whole job.
4. Contacts for the owner, the occupants, and the site manager. The standard requires interviews with the people who know the property. You’re often the fastest route to them, especially the seller.
5. Any prior environmental reports. An old Phase 1, a Phase 2, a tank closure report, a remediation letter, anything. A seller who has one and doesn’t mention it isn’t unusual; asking directly costs nothing.
6. What you already know about the site. Old tanks, a well, a septic system, a former grove or pasture, a neighbor who used to run equipment out of the back acreage. Write it down even if it seems minor. This is part of your legal obligation under All Appropriate Inquiries, not a courtesy (more on that in our guide).
7. Your answers to the user questionnaire. The ASTM standard includes a short set of questions for the buyer: why you’re doing the assessment, whether you have specialized knowledge of the property, and whether the purchase price looks right against fair market value. They sound like paperwork. Your answers become part of the report.
8. The environmental lien search, or who’s ordering it. Searching for recorded environmental cleanup liens is the buyer’s responsibility under the federal rule. Most buyers get it through their title company. Decide at the start whether that’s you or us, so it doesn’t fall between the two.
9. Your lender’s requirements, in writing. Some lenders have their own scope, their own format, or a list of parties who need to rely on the report. Knowing that on day one is far cheaper than reissuing the report on day twelve.
10. Your closing date and the last day of your inspection period. We plan the job backward from those dates.

What to Expect, Week by Week

Turnaround is one to two weeks from the day it’s ordered. Complicated histories and multi-parcel assemblages can take longer, and if yours is one of those, you’ll hear it at the start rather than at the deadline.

Week one: records and the site visit. The records review starts right away: historical aerials back to 1940, fire insurance maps, city directories, and the federal, state, and local databases, including Florida’s own contamination and storage tank records. We’re typically on the site within the first week. Expect a call to confirm access, and expect questions about anything the records turned up that doesn’t match what you told us.

Week two: interviews and the report. Interviews with the owner, occupants, and where needed, local officials, get finished. Then the environmental professional writes up the findings, forms an opinion, and signs the report.

What you’ll be asked during the job. Mostly follow-ups. An aerial from 1968 shows a structure nobody mentioned. The county has a permit for a tank that isn’t on the site anymore. You won’t always have the answer, and that’s fine. “I don’t know” is a real answer, and the report will say so.

What You’ll Receive: The Phase 1 ESA Report, Section by Section

A Phase 1 ESA report is usually a PDF of a few dozen pages of text followed by a much thicker stack of appendices. It looks intimidating. It’s organized the same way almost every time, because the federal rule and the ASTM standard dictate what has to be in it. EPA even publishes its own checklist of what an All Appropriate Inquiries report must contain.

Here’s what you’ll find, roughly in order:

1. Summary. The findings and conclusions on one or two pages. Most people stop here. You shouldn’t, but it’s the right place to start.
2. Scope and limitations. What was done, what wasn’t, and any deviations from the standard. If the site visit couldn’t reach part of the property, it says so here.
3. Site description. Location, size, current use, and a description of the adjoining properties.
4. User-provided information. Your questionnaire answers, the lien search results, and anything you disclosed. Read this one carefully: it’s your part of the record.
5. Records review. What the databases, aerials, and historical sources showed, for the property and its neighbors, back to 1940 or first developed use.
6. Site reconnaissance. What the environmental professional saw on the ground, with photographs.
7. Interviews. Who was interviewed, who couldn’t be reached, and what they said.
8. Findings, opinions, and conclusions. The core of the document. Findings are what was found. The opinion is the environmental professional’s judgment about what those findings mean. The conclusions sort them into the standard’s categories: recognized environmental conditions (RECs), controlled RECs, historical RECs, and de minimis conditions. If the report does identify a REC, the section below on what happens next covers the usual path.
9. Data gaps. Anything the professional couldn’t find or confirm, and whether it’s significant.
10. Recommendations. If the professional believes more investigation is warranted, it goes here. A clean report often has none.
11. Signature and qualifications. The environmental professional’s signed declaration and qualifications. Somebody has to put their name on it.
12. Appendices. Maps, the database report, historical aerials and maps, photographs, interview records, regulatory correspondence, and qualifications.

How to Read It in Ten Minutes

You don’t need to read two hundred pages to know where you stand. Read these four things, in this order:

1. The conclusions. Is there a REC or not? That’s the answer to the question you actually asked.
2. The data gaps. Are any of them called significant? A significant data gap means the professional couldn’t rule something out. On a parcel with eighty years of history, some gaps are normal. What matters is whether the report says they change the conclusion.
3. The component dates. (See the next section. This is the one people skip.)
4. Your own section. Check that what you disclosed is recorded correctly, and that the lien search is in there.

Then read the rest at your own pace.

The Date That Matters Isn’t on the Cover

A Phase 1 report has one date on the cover and several inside it, and the ones inside are the ones your closing depends on.

Under the federal rule, five pieces of the assessment have to be done or updated within 180 days before you take title: the interviews, the lien search, the government records review, the site visit, and the environmental professional’s declaration. The whole assessment has to fall within a year. The report lists when each piece was done.

The 180-day clock runs from the earliest of those five dates, not from the day the report was delivered. If the records review happened three weeks before the report was signed, you have three fewer weeks than the cover suggests. On a deal that slips, that’s the difference between closing on the report you have and ordering an update.

That rule isn’t there to generate extra work. Properties change: a tenant moves in, a tank gets pulled, a neighbor has a spill. The rule assumes that six months is long enough for something to happen, and in a market that moves like Southwest Florida’s, that’s not an unreasonable assumption.

Who Can Rely on the Report

A Phase 1 is written for a named user, usually whoever ordered it. If your lender, a partner, or a second buyer entity needs to rely on it too, they generally need to be named in the report or given a reliance letter from the firm that wrote it.

Sort this out before the report is written. Adding a party afterward is usually doable, but it’s paperwork you’d rather not be chasing in the last week of an inspection period. This is why item 9 on the checklist asks for your lender’s requirements in writing.

If the Report Finds Something

Most Phase 1s come back with no recognized environmental conditions, and the report goes in the file as the record of your due diligence.

If yours identifies a REC, it’s not a dead deal. It’s a different next step, usually a Phase 2 assessment, which is where soil or groundwater sampling actually happens. Deals close on properties with RECs all the time, adjusted through price, escrow, or a Phase 2 that shows the problem is smaller than the record made it look. It’s not high stakes, because there’s almost always a solution. The question is what it costs and whether that still works for your project.

Creek doesn’t perform Phase 2 sampling in house, and we’d rather say so up front. We’ll explain what the finding means, what the realistic outcomes look like, and connect you with a firm that does that work.

Working With Creek

Creek Engineering has been serving Southwest Florida since 2002, across Charlotte, Sarasota, Lee, Collier, DeSoto, Manatee, Hendry, and Hillsborough counties. We pull the Florida records ourselves, we get our boots on the parcel ourselves, and we’ll tell you honestly whether a finding is serious.

A Phase 1 answers the contamination question. It doesn’t answer whether the site can take the building, the septic system, or the stormwater your project needs. Because we do the geotechnical, civil, environmental, and septic engineering on these same parcels, the Phase 1 is the start of the conversation about your site rather than the end of it.

If you’re under contract and need a Phase 1 before your inspection period closes, get in touch with your parcel numbers and your deadline, and we’ll tell you what the scope looks like.
