Conditions and access
Mature trees, steep older-subdivision pitches, and tight infill lots near downtown all add labor time a newer open-lot ranch wouldn't need.
Scope and materials
Pin down exactly where the repair boundary sits, what gets tested once it's finished, and how debris and old material are hauled away.
Permits and specialist input
Naperville's own stormwater rules can apply if a project changes drainage or adds new routing — check with the city and your provider whether it affects your project.
