What matters for project planning
The City of Champaign requires a permit (a $70 fee) for new or modified connections to the municipal stormwater drainage system and is the permitting authority for land-disturbing activity, requiring an approved stormwater control plan for qualifying construction projects. Champaign coordinates that permitting with Champaign County, the City of Urbana, the University of Illinois, and the Village of Savoy through the Champaign County Stormwater Partnership's shared MS4 permit program. New decks and other land-disturbing site work can require a permit and a stormwater plan from the City of Champaign, worth checking before construction begins.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
