§ 9-32.120. Drainage Standards

All proposed drainage facilities shall respect the natural (before development) hydrologic characteristics of the subject terrain, preserve major drainage channels in their natural state, and be designed in such a manner as to preserve the public health, safety, or welfare. The provisions of the following standards shall apply to all land subject to the regulations of this Article and shall be in addition to the provisions of the adopted version of the Uniform Building Code, Chapters 6 and 7 of the Ventura County Land Development Manual, or any other applicable drainage requirements:

A.

To the maximum feasible extent, all natural drainage courses serving major drainage areas and containing significant perennial vegetation which may constitute a significant wildlife habitat should remain in their natural state. Alterations to such drainage courses may be allowed if the application of this Section will result in upstream or downstream flooding hazards for which there is no other feasible means of mitigation consistent with the findings (Section 9-32.050 of this Chapter).

B.

In the event off-site drainage facilities will be required to handle increased runoff from any development subject to these regulations, interim drainage facilities which provide for no increase in peak runoff from a 10 year storm shall be constructed and maintained until such time as the permanent facilities are completed.

C.

The overall drainage system shall be completed and made operational at the earliest possible time during construction or shall otherwise be provided for in a manner acceptable to the City. If a development is to be phased, all downstream (including interim facilities within the project area or required interim off-site drainage facilities) elements of the approved drainage facilities will be completed or otherwise provided for in a manner acceptable to the City before the completion of the upstream phases.

D.

A drainage plan, including the text, maps, and diagrams, shall be submitted to the City as a part of any formal application for development under these regulations. The City Engineer in consultation with the Director, or their designees, shall review such submissions for completeness, adequacy, and conformance with the above and other applicable standards.
