About Plexus Impact
Better tools for environmental review.
Plexus Impact helps planners, engineers, environmental consultants, and developers move through environmental review from the earliest stages of a project to the final report, with every conclusion linked back to its source.
Who it is for
Environmental review is one of the most important parts of planning. It protects our communities, natural resources, and public health while shaping the housing, infrastructure, energy, and public projects we depend on.
The challenge is not environmental review itself. Thorough, evidence-based review is essential. The challenge is that completing it takes an enormous amount of time. Professionals must navigate regulations, agency guidance, technical manuals, precedent projects, environmental datasets, field studies, and technical analyses before they can produce a record that agencies and the public can trust.
Those delays have real costs. They increase the price of delivering housing, infrastructure, and public projects, driving up costs for governments, developers, and ultimately the communities those projects are meant to serve.
Much of the information needed to complete these reviews already exists. It is simply scattered across thousands of reports, regulations, guidance documents, maps, and datasets that were never designed to work together.
We built Plexus Impact to change that.
One place for the entire process
From a project description to a final deliverable
Start with a project description. Plexus helps determine which review framework applies, identifies the likely permits and agencies, surfaces the relevant regulations and guidance, and finds comparable projects that inform the review. As the project develops, it helps organize field data, identify environmental constraints, understand previous determinations and mitigation measures, perform technical analyses, and draft reports with every conclusion linked back to its source.
Rather than jumping between dozens of websites, reports, spreadsheets, GIS layers, and guidance documents, professionals work through the review in one connected environment.
Our approach
Environmental review depends on professional judgment. It always will.
Plexus supports that judgment, it does not replace it. Every recommendation is grounded in regulations, agency guidance, technical manuals, or precedent projects, and every step stays transparent and verifiable. The planner, engineer, or environmental consultant remains responsible for the decisions. Plexus helps them reach those decisions faster, and with better access to information.
Looking ahead
A broader vision for planning
We are starting with environmental review because it is one of the biggest bottlenecks to delivering projects that matter. Planning is full of fragmented processes, disconnected information, and repetitive work. We believe software can bring those pieces together without sacrificing rigor, transparency, or accountability.
Our goal is direct: build the tools that let professionals spend less time searching for information and more time applying their expertise, so good projects move forward faster.
Built with the practitioners who use it.
