Do you support prioritizing data center expansion in your community despite potential resource usage concerns?

The Mississippi River Cities and Towns Initiative (MRCTI) has released new evaluation resources to help member communities navigate data center development proposals. This guidance includes a fiscal evaluation framework and a wishlist developed with the Sierra Club as interest from AI infrastructure developers surges across the river basin.

Why it matters

With over 75 percent of planned U.S. data centers slated for the South and Midwest, local officials require standardized tools to assess the impact of these projects on water and utility services. These resources aim to provide a more rigorous basis for evaluating the long-term fiscal returns versus the infrastructure risks posed by massive AI buildouts.

Illinois currently hosts 139 operational data centers with an additional 100 in development, highlighting the concentration of capacity in the Midwest. Nationally, there are more than 3,000 active data centers as monthly construction spending reaches 4.4 billion dollars.

The players

Mississippi River Cities and Towns Initiative

A coalition of over 100 mayors representing river communities across the United States focused on regional economic and infrastructure advocacy.

Sierra Club

An environmental organization that collaborated on the development of the data center wishlist to establish sustainability benchmarks.

Future Caucus of the Missouri House of Representatives

A bipartisan group of legislators that originated the fiscal evaluation framework for data center developments.

The details

The fiscal evaluation framework, originating from the Future Caucus of the Missouri House of Representatives, provides mayors with a standardized ledger to calculate potential tax revenue against the cost of municipal service upgrades. The data center wishlist—produced with the Sierra Club—outlines ecological benchmarks for developers, such as requirements for site water usage and utility grid integration. These tools are designed to move negotiations beyond simple land-use agreements into quantitative assessments of utility strain.

The Tech Race

This development marks a departure from the historical model of states competing solely on tax incentives to attract data center investment. Local leaders are now formalizing criteria to ensure AI infrastructure projects do not overwhelm regional utility grids or existing water supplies.

Municipalities across the Mississippi River Basin, including those in Minnesota, Arkansas, and Louisiana, will now use these frameworks to evaluate pending project proposals. Local residents can expect these benchmarks to influence future zoning decisions and the public utility rates associated with high-capacity data center growth.

The takeaway

The MRCTI guidelines provide a baseline for mayors to demand more equitable fiscal outcomes from AI developers. Watch for the adoption rates of these fiscal frameworks in the upcoming legislative sessions of member cities as a litmus test for municipal leverage in the AI buildout.
