Endangered Species Survey habitat - tallgrass prairie with native wildflowers and bumble bee in Illinois

Endangered Species Survey work determines whether a development site harbors federally or state-listed threatened and endangered species — and what that means for your project timeline, permits, and costs. In Illinois, construction projects near prairies, wetlands, and mature forests increasingly trigger the need for an Endangered Species Survey before ground can be broken. A3 Environmental

Green Infrastructure Grant funded bioswale filtering stormwater in Illinois

Green Infrastructure Grant programs fund bioswales, stormwater wetlands, and native plantings that reduce nonpoint source pollution in Illinois communities. The IEPA’s Green Infrastructure Grant Opportunities (GIGO) program is one of the most accessible funding sources for municipalities ready to replace aging stormwater infrastructure with nature-based solutions. A3 Environmental Consultants (A3E) helped the City of Rockford,

Watershed Plan target area - creek winding through rural Illinois farmland

Watershed Plan development is the foundation of effective water quality restoration in Illinois. A well-built Watershed Plan identifies pollution sources, proposes science-based solutions, and creates the roadmap that unlocks federal funding — including IEPA Section 319(h) grants. Without an EPA-approved Watershed Plan, most communities cannot access implementation funding for streambank stabilization, buffer installation, or habitat

319 Grant funded streambank stabilization project in Dixon Illinois

319 Grant funding supports watershed restoration projects that reduce nonpoint source pollution in impaired waterways. Administered by state environmental agencies under Section 319(h) of the Clean Water Act, these competitive grants support streambank stabilization, sediment control, native plantings, and stormwater best management practices. In Illinois, the IEPA manages the 319 Grant program with funding from

Phase 1 Environmental Site Assessment Cost - environmental consultant inspecting commercial property

A Phase 1 Environmental Site Assessment cost typically falls between $2,200 and $4,000. Most standard commercial properties fall at the lower end of that range. Complex sites — former industrial facilities, brownfields, or properties with long operational histories — push toward the higher end. The price covers a records review of federal, state, and local

Thumb Naturalization Stream Project Belvidere IL

The City of Belvidere, Illinois engaged C.E.S., Inc. to address chronic sediment accumulation and maintenance challenges in the 6th Street Channel, a municipal stormwater conveyance that had become increasingly difficult and costly to maintain. The City’s original plan called for lining the channel with concrete, but regulatory agencies would not permit a hardened channel due

Woodale Park District NEPA

When federal dollars fund a community project, the National Environmental Policy Act (NEPA) requires a thorough environmental review before construction begins. For the Wood Dale Park District’s Central Park redevelopment — a $324,475 HUD-funded project in DuPage County, Illinois — that meant a full 24 CFR Part 58 NEPA Environmental Review to clear the site

OSFM Illinois

Public utility provider(s) in Northern Illinois rely on A3 Environmental Consultants (A3E) to manage their Underground Storage Tank (UST) removal and closures. In addition, A3E provides UST Compliance Audits to keep our clients on the right side of the Office of the State Fire Marshal (OSFM). Our clients work hard to avoid regulatory compliance issues

NEPA for Inner City Muslim Action Network

When a federally funded health center project moves forward, a NEPA Environmental Assessment is the gatekeeping document that determines whether construction can proceed. The National Environmental Policy Act (NEPA) requires federal agencies to evaluate the environmental consequences of proposed actions before committing resources — and for the Inner-City Muslim Action Network (IMAN), that meant hiring

Environmental Record Search

An environmental record search is a regulatory and historical database review that tells you whether a commercial property — or any of its neighbors — has a documented history of contamination, before you buy, lend, or develop. It is the fastest, lowest-cost form of environmental due diligence, and for many low-risk deals it is all

Confidentiality regarding Phase 1 Environmental Reports

Buying commercial real estate without a Phase 1 Environmental Report is like buying a used car without lifting the hood. Whether it’s a strip mall in Michigan or a logistics hub in Nevada, these reports are essential tools for assessing environmental risk —and they’re not always available for public consumption. In this post, we unpack

drawn image of two people reviewing the contents of their Phase 1 Environmental reports

Phase 1 Environmental Reports serve as pivotal documents in assessing environmental risks associated with a property. Central to their integrity is the assurance of confidentiality, a cornerstone of professional practice within the environmental consulting industry. Access to these reports is typically restricted to parties directly involved in the contractual agreement governing their production. Without such

Environmental Vocabulary

For many people, purchasing a commercial property is a once-in-a-lifetime event. It’s not surprising that most don’t know the terminology. There’s no such thing as a “Level One Environmental”. It’s called a “Phase 1 Environmental Site Assessment”.  This post is dedicated to all the ways people get their terminology understandably wrong. It makes it difficult

The Golden Gate Bridge is an amazing structure – massive, sitting across a fault line, beautiful and elegant in a way that complements nature and the surrounding city. The Hoover Dam is enormous too. It holds back mind-boggling volumes of water. It makes electricity. It was built with architectural style as well as engineering grace.

Leaking underground storage tank LUST

Discovering a leaking underground storage tank (UST) on your property is like finding out your basement has a swimming pool you didn’t order—and it’s full of gasoline. Whether you’re preparing to buy, sell, or simply manage a site, a UST is rarely a welcome surprise. Regulators are strict, buyers get nervous, and cleanup costs can

Cleanup Liabilities

I thought this article about environmental cleanup liabilities was great information that most people in a property transaction never hear about. You can read the whole thing by clicking here.   Lenders, borrowers, purchasers, sellers, and even contractors sometimes get annoyed with environmental lawyers when we insist on reviewing Phase I Environmental Site Assessment (ESA)

WETLAND Lisle IL

In August 2024, A3 Environmental Consultants completed a wetland delineation for Professional Environmental Engineers, Inc. at a 23-acre site along Lincoln Avenue in Lisle, DuPage County, Illinois. The area, a mix of residential, commercial, and recreational land use, required a thorough evaluation to determine the presence of wetlands and any potentially critical habitats. This project

Environmental Lawyer

As an environmental consultant, we’re frequently asked for advice that veers out of our lane and into what environmental lawyers do best. While I’ve never met or talked to the environmental lawyers over at Spencer Fane, they seem to have some pretty good, concise, advice about environmental law. The following is gleaned from their website

A3 CCDD LPC 663, LPC 662, LPC 667

You’re probably wondering how you’ve lived so long on this planet without ever knowing how Illinois landfill pricing works. Settle down nerd. I’m not going to answer every question you have, just give you a slightly better understanding. This article is designed for regular people, new environmental consultants and trucking companies that haul clean fill,

Clean Construction Demolition Debris CCDD

The following is a guide for regular people regarding CCDD – which stands for Clean Construction Demolition Debris. In this primer, we’re going to take a beat to cover background information you’ll need to keep in mind while reading. I’m making the assumption that you, the reader, is not an engineer or environmental consultant but is in an industry that is touched by these regulations.

A front end loader filling a dump truck with clean fill

The Illinois MAC value table sets the Maximum Allowable Concentration (MAC) limits that decide whether soil qualifies as clean fill (CCDD). MAC refers to the maximum allowable levels of contamination in clean fill. CCDD stands for Clean Construction Demolition Debris and is a body of laws from the IEPA (Illinois EPA) that regulate clean fill

Free Clean Fill Dirt Near Me

Clean fill cost in Illinois comes down to three things: the science, the disposal, and the trucking. CCDD stands for Clean Construction Demolition Debris. Similarly, USF is an abbreviation for Uncontaminated Soil Fill. In Illinois both of these terms are used interchangeably as “Clean Fill”. Both of these terms refer to a body of laws

a stack of rusted barrels waiting for environmental remediation

When most people hear the phrase Environmental Remediation, they picture white-suited consultants scrubbing away spills with oversized toothbrushes or magically restoring soil overnight. The reality is far less cinematic and far more complex. Contamination doesn’t just disappear—it lingers, shifts, and reshapes the way we use land for decades, even centuries. At A3 Environmental Consultants, we

Brownfield

What is a brownfield? It’s not a fancy eco-buzzword—it’s an abandoned piece of real estate that once held a gas station, a factory, or even a strip mall. Instead of thriving, these properties sit empty for years, fenced off and avoided, because they’re weighed down by one ugly truth: real or suspected contamination. Brownfields are

Due Diligence Period

Environmental due diligence is where optimism meets reality when buying commercial real estate. Sellers love to highlight the shiny features of a property—fresh paint, prime location, a “can’t miss” investment—but it’s the buyer’s job to look for the warts hiding under the surface. That’s where environmental due diligence comes in. Just because you can’t see

This 3rd party environmental review scope of work defines what A3E delivers. The review will include a thorough and detailed review of the client provided report(s) (i.e. Phase I ESA, Phase II ESA, RSRA, etc.), an assessment of any conditions that could pose a potential environmental concern to the Subject Property, and professional opinion statements

Phase I Environmental Cost

As with all things, prices for a Phase I Environmental Site Assessment can vary based on a number of factors. At A3E, we take pride in providing clear, competitive pricing, but there’s a lot that goes into determining the true cost of a Phase I ESA. Understanding those factors can help you make a smarter

Watershed Plan Development for the Lower Rock River Basin Project Profile

Counties across Northern Illinois face a familiar challenge: impaired waterways, regulatory pressure, and limited budgets colliding with very real water quality problems. A well-developed watershed plan is often the difference between reacting to impairment listings and proactively improving streams, lakes, and downstream receiving waters. Over the past decade, A3 Environmental Consultants – known as Olson

Wetland Mitigation Bank, Bass Creek Watershed, Afton Wisconsin

A wetland mitigation bank is only as successful as its planning, performance standards, and long-term monitoring. For municipal and government stakeholders, the difference between a functional public asset and a regulatory headache often comes down to early technical decisions and sustained agency coordination. In Afton, Wisconsin, the Bass Creek Wetland Mitigation Bank demonstrates how a

The South Branch Initiative (SBI) is one of Shedd’s

Commercial Lenders

Commercial lenders balance risk, cost, and speed on every deal. But there’s a blind spot: environmental reports. Too often, the drive to reduce borrower costs pushes lenders into a “low-bidder wins” model. At first glance, this looks efficient. In practice, it exposes lenders to unnecessary risk and borrowers to needless expense. For these banks, environmental

Two hands shaking over a document represeting a commercial real estate agent and an environmental consultants agreement

Commercial real estate professionals know the clock doesn’t start ticking when the ink dries on the contract—it’s been ticking the whole time. The deal isn’t done until the money moves, and every commercial real estate professional knows there’s a minefield of due diligence steps that can stall, shrink, or sink a closing. One of the

Environmental Desktop Report

An Environmental Desktop Report is a fast, ESRI-based screening of regulatory and historical records that tells a lender whether a commercial property — or any of its neighbors — carries documented environmental risk, without the cost or delay of a full Phase 1 ESA. In commercial lending, time and risk tolerance are constantly at odds:

Environmental Investigations

If you’re buying commercial real estate, you’re not just purchasing walls and dirt — you’re inheriting its history. That means if the previous owner had a love affair with toxic solvents in 1972, you might be picking up the tab for the cleanup in 2025. This is where Phase 1 ESA and Phase 2 ESA

Environmental Database Reports

An Environmental Database Report is the fastest way a bank can see whether a commercial property — or any of its neighbors — carries a documented history of contamination before money changes hands. Also known as an EDR, Environmental Screen (ES), Desktop Assessment, or Desktop Due Diligence, this streamlined tool delivers high-level environmental risk data

Environmental Study

The gold standard comes from the American Society for Testing and Materials (ASTM). Think of it like GAAP for accounting or ISO for manufacturing—ASTM sets the playbook so every Phase I Environmental Site Assessment (ESA) is done the same way, every time. That means no surprises for you, and confidence for banks, investors, and anyone

Man performing an environmental inspection

In 2025, environmental inspections are more than just a box to check before closing a deal — they are your shield against future liabilities. For business owners nationwide, a Phase I Environmental Site Assessment (ESA) is the gold standard in due diligence. Conducted by trained Environmental Professionals (EPs), these inspections uncover past, present, or potential

RSRA Record Search Radius Report

Developed by the Small Business Administration (SBA) for SBA-backed loans, the RSRA pairs a comprehensive database search with a

A picture depicting an all cash buyer of environmental reports

An environmental report is any documented review of a property’s contamination history — from a quick database screen to a full Phase I ESA — and for all-cash buyers it is the one piece of due diligence no lender is forcing you to order, which is exactly why it deserves a closer look. Everyone buying

Environmental due diligence in CRE is more than a checklist—it’s your financial seatbelt. At the center of it is the Phase 1 Environmental Site Assessment (ESA), a tool designed to uncover potential environmental risks before you commit to a property.

Two hands holding a tiny tree show how REC Removal Made Simple for Banks and Property Buyers

At A3 Environmental Consultants, we help you navigate the  landscape, from identification to resolution,

Environmental Inspection & Investigation

When you hear “environmental inspection” in commercial real estate (CRE), think of it as the property’s medical check-up before you commit to buying it. In the context of a Phase 1 Environmental Site Assessment (ESA), this inspection is a critical component — part detective work, part science, and entirely about protecting your investment. For CRE
