A development package is the full engineering submission for a planning application. The reports and drawings are coordinated as one engineering assignment.
It suits official plan amendments, zoning by-law amendments, site plan control, and subdivision applications. The scope is set from your pre-consultation study list.
The package typically contains four documents. A servicing report, a stormwater report, a servicing plan, and a grading plan.
Preparing them as a set is the point. Flows, inverts, storage volumes, and levels remain consistent because the engineering team coordinates them across every document.
Reviewers cross-check documents against each other, so coordinated inputs and calculations reduce avoidable conflicts between reports and drawings.
The two reports at the centre of the package are the Functional Servicing Report and the Stormwater Management Report. Engineering work is reviewed and sealed by a licensed Ontario Professional Engineer, as applicable.
