A drainage review and approval is required when any development proposal is subject to a City permit. All proposals for development or redevelopment, whether public or private, which are submitted to the City for review and approval shall conform to these requirements which are to be used as the basis for review and approval of design and construction.

Development projects that capture and infiltrate all storm water on site are also subject to these regulations, since these projects contribute to ground water and have a probability of contributing storm water to the City storm water system in the event the design capacity is exceeded; or the system is compromised or fails.

Not all of the minimum requirements apply to every development or redevelopment project. The applicability varies depending on the type and size of the project. The flow charts in Figures 11.1 and 11.2 shall be used to determine which of the minimum requirements apply.
