The record

Why it exists

“The Purpose of the Fee. The costs of extending the same level of storm drainage protection to the newly developing residences and businesses as is provided to the existing community (that has largely paid for the existing system) can be calculated, a fee imposed and collected. The Fee revenues can then be used to expand the storm drainage facilities necessary to extend that same level of services.”

Where it applies

“Storm Drainage collection system is an infrastructure that will also consist of two DIF schedules, one for each of the GC (General City) and OR (Ontario Ranch) areas of the City. Again this is due to significantly differing capital needs of the two areas. The first part of this chapter will be directed at explaining the nexus and the specific GC Storm drainage DIFs.”

About these figures

Quoted, not summarized. Every amount and fact on this page is copied from the official document it links to. If we couldn’t find something in a document, we leave it blank instead of guessing.

Before any discounts. Some fees offer credits, waivers or phase-ins. They’re listed above but not subtracted, because whether you qualify depends on your project.

Check the date. Fees change. This page shows what was in force on the date at the top, with a link to the document that set it, so you can confirm the current amount yourself. How all of this is put together.
