Driveways & sidewalks in DuPont: what to know

The state residential exemption text lists sidewalks and driveways with no height limit, though a footnote says other code requirements may apply. The frontage piece is therefore checked against the city’s right-of-way chapter, which counts sidewalk and driveway-opening work as right-of-way work and requires a permit before it begins. A lane or sidewalk closure needs its own permit line.

The city’s 2011 Public Works Standards add two approach rules. Driveways directly giving access onto arterials will be denied if alternate access is available, and the owner whose property an approach serves maintains that approach. Dimensions and slopes are set by city drawings 3.1-1 and 3.1-2, so the apron geometry is confirmed with the city before anything is shaped.

Permits and rules in DuPont

Before quoting, we confirm the frontage line with the city, since the chapter names sidewalks and driveway openings but not curb cuts or approaches. We check the application contents against the chapter’s list of affected infrastructure, which names street pavement, curb and gutter, sidewalks, and utilities. The approach decision time stays open until the city replies in writing.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Split the job into private slab and frontage piece
Confirm the frontage line before layout is drawn
Check the arterial access rule before the approach
Record the owner’s approach upkeep duty in the scope

Questions from DuPont homeowners

Does a DuPont driveway need a permit at all?

The state residential exemption text lists sidewalks and driveways with no height limit, but a footnote says other code requirements may apply. Work in the right-of-way is a separate track: the city’s chapter requires a permit before work on sidewalks or driveway openings begins, so we confirm the frontage line first.

Who keeps a DuPont driveway approach in repair?

The 2011 Public Works Standards place approach maintenance on the owner whose property the approach serves. The city’s maintenance chapter also puts sidewalk and driveway upkeep on the owner, and a repair the city orders runs through a public works permit.

Can a DuPont driveway connect straight to an arterial?

The 2011 Public Works Standards say a driveway directly giving access onto an arterial will be denied when alternate access is available. We check the lot’s other access first, and any arterial connection waits for the city’s written answer.
