Virginia's Largest Municipal Nutrient Credit Bank

What a Nutrient Credit Bank Is

Virginia's nutrient credit trading program exists under the authority of the Virginia Department of Environmental Quality. It allows entities that generate water-quality improvement — by reducing the amount of nitrogen and phosphorus entering the Chesapeake Bay watershed — to earn credits that other entities can purchase to offset their own discharge obligations.

A nutrient credit bank works by improving land in ways that demonstrably reduce nutrient runoff. Planting trees is one of the most effective methods: tree canopy intercepts rainfall, stabilizes soil, absorbs nitrogen, and prevents runoff from reaching streams and rivers that feed into the Chesapeake Bay watershed. The credit market values these instruments at $20,000 to $30,000 per credit. Purcellville's bank produced 75 to 76 credits.

The Aberdeen Property

The Aberdeen property is a tract of 93 to 95 acres of town-owned land in Purcellville. Prior to the nutrient bank initiative, the land was undeveloped but not actively managed for environmental benefit or revenue generation. The Fraser administration identified the property as an opportunity to generate a recurring municipal revenue stream through conservation — an approach that aligned with the town's stated environmental commitments while simultaneously improving the town's long-term fiscal position.

The land was placed under a conservation structure and formally enrolled in Virginia's nutrient credit trading program through the DEQ approval process. The centerpiece was the planting of 111,000 trees, executed in partnership with Davey Resource Group — a national environmental and forestry services firm — at a scale designed to maximize canopy coverage and its associated water-quality benefits.
