What matters for project planning
The stormwater-connection permit is the provision that matters most here. A perimeter drainage system has to discharge somewhere, and if that discharge is a new or modified connection to the municipal stormwater drainage system, Champaign requires a permit for it — currently carrying a $70 fee. That turns 'where does the sump discharge' from an afterthought into a permitted decision. Excavation for exterior drainage is separately land-disturbing activity, for which the city can require an approved stormwater control plan. Near the Urbana, Savoy or University boundaries, confirm which authority actually reviews your address.

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 specifics with the appropriate Champaign authority and the selected provider before work begins.
