Crash Dashboard
What this shows: Every reported traffic crash in Champaign, Urbana, and Savoy since 2014, mapped, with a report builder for any city, street, or intersection.
Why it matters: Street design decides who gets hurt. Knowing where people are injured and killed is the first step to fixing those streets.

Value Per Acre
What this shows: Property value and property tax per acre for every parcel in Champaign County, with filters for each city and a 3D view.
Why it matters: Compact, walkable blocks carry far more of the tax base per acre than parking lots, strip development, and vacant land, and they cost less to serve.

Vacant Land
What this shows: Every vacant parcel in Champaign County by type, including subdivision land still assessed at farmland rates.
Why it matters: Empty lots in town are where new homes and businesses could go, and they produce almost nothing while the city maintains the streets and pipes around them.

Zoning Districts
What this shows: The city's legal zoning framework, block by block.
Why it matters: Before we can fix affordability, we need to see where current rules allow homes, limit homes, or block them entirely.
Explore Zoning DistrictsResidential Permit Map
What this shows: Where new residential permits have actually been issued over the last decade.
Why it matters: This is the real-world production pattern, and it helps us identify where Champaign is adding homes and where we are falling behind.
Explore Permit ActivityWhere Can I Build A type?
What this shows: Where common housing types are allowed by right, allowed conditionally, or not allowed.
Why it matters: If we want abundance, we have to legalize everyday housing options in more neighborhoods, not just in a few zones.
