Local Associations Building a Better Community
The DMV Alliance is a unified platform for Washington, D.C., Maryland, and Virginia communities. By collaborating through a local voice, we unify the resources and information of local industry associations to ensure better public access to accurate information and additional resources for everyone.

01 / THE BASICS
One building. Five community questions.
The honest answer is rarely a single number. Design, climate, operating conditions, and local agreements all matter.
DMV / EXPLORE BY JURISDICTION
Three public records. Three local guides.
Compare data center and digital infrastructure evidence without mixing statewide estimates, county records, and District network measures.
02 / COMPARISON LAB
Change the assumptions.
See what changes.
These calculators explain relationships—not a specific project. Replace every starting value with locally sourced data before making a public claim.
Load a practical starting point for the selected topic, then replace each assumption with local project information.
SITE / PROJECT INPUT COMPARISON
How much separation and landscape restoration are planned?
Distance from homes is a starting point—not a universal safety rule. A credible siting review identifies the closest receptor, terrain, transmission routes, emergency access, and future land use.
Siting details and assumptions+
Project inputs, not a score: Separation and landscape restoration should be reviewed independently against local zoning, future land use, emergency access, terrain, utilities, and the approved landscape plan.
Plant for the place: Use locally appropriate native trees, shrubs, and groundcover sized for their mature canopy. Ask where the percentage is measured, how preserved canopy is counted, and who maintains new planting.
The 1,000-foot separation is a screening input; local zoning, future land use, terrain, and the approved site plan determine whether it is appropriate.
DOCUMENTED SEPARATION INPUT · VERIFY LOCALLY
A project-specific review is still required.
Ask the developer: What is the nearest home today and under the future land-use plan, and where will the mature native canopy be measured?
THE EVIDENCE GUIDE
A number without context is just a talking point.
Use the same six-part label on every public claim. It makes comparisons fairer and source updates much easier later.
BREAKDOWN OF A CREDIBLE CLAIM
In Loudoun County, data centers added $16 billion in real-property value in 2024, bringing the total to $41 billion, according to Loudoun County’s FY2026 budget materials.
Why this claim works
It is positive without being vague. It names the place, the type of value, the one-year increase, the resulting total, the period, and the government source. It does not turn assessed property value into jobs, cash in hand, or a guarantee of lower taxes.
What to ask next: How much of that assessed value becomes recurring local revenue, how volatile is the equipment tax base, and which services or reserves receive the money?
