(A) Plan required.
(1) Unless waived by the City Engineer/Public Works Director, all work requiring a grading permit or a grading plan shall be required to have an approved erosion control plan. If the requirement for an erosion control plan has been waived, the City Engineer/Public Works Director may still require the installation of an erosion control system to control erosion and provide safety during grading.
(2) As determined by the City Engineer/Public Works Director, an erosion control plan can be a part of the grading plan or a separate plan by itself reviewed and approved by the City Engineer/Public Works Director.
(3) No activity authorized under a grading permit shall be conducted unless an erosion control plan has been approved or the City Engineer/Public Works Director has waived the requirement for an erosion control plan.
(4) The City Engineer/Public Works Director may waive or vary the required contents of an erosion control plan for grading on single residential lot projects.
(5) An erosion control plan is required for a project if the City Engineer/Public Works Director determines that erosion or sediment discharge from the project could adversely affect adjacent properties.
(6) An approved erosion control plan from the previous year shall be updated and submitted for approval, if necessary, prior to the start of the rainy season, as determined by the City Engineer/Public Works Director, to reflect any changed conditions where the grading or other land disturbance activity is continuing. Updating of the erosion control plan may also be required at any time during construction if deemed necessary by the City Engineer/Public Works Director or his or her designee. Updating of the erosion control plan will also be required for phases of construction not covered by any previously approved erosion control plan.
(7) All erosion control plans must be approved, and erosion control devices installed and certified and inspected as being properly constructed by the civil engineer or a certified QSD or QSP. Sediment control must be continuously maintained throughout the construction process.
(B) Contents of erosion control plans. An erosion control plan shall include, but is not limited to, the following information:
(1) Details of all BMPs necessary to implement and satisfy the applicable requirements and standards set forth in § 7.90.270 (Erosion Control Systems) and necessary to protect the quality of receiving waters as defined in the Clean Water Act and adjoining public or private property from damage by erosion, flooding, or mud and/or debris deposits which may originate from the site or result from the grading work.
(2) A 24-hour telephone number of the person responsible for performing emergency erosion control work.
(3) The stamp and signature of the civil engineer who prepared the erosion control plan.
(4) The erosion control general notes (copies available from the Engineering Department).
(5) Identification of all desilting and erosion protection facilities necessary to protect adjacent property from sediment deposition.
(6) Identification of the streets and drainage devices that will be completed and paved prior to the start of the rainy season, as determined by the City Engineer/Public Works Director.
(7) Provision for the placement of gravel bags, slope planting or other measures to control erosion from all slopes above and adjacent to roads open to the public.
(8) Provision for maintaining access to desilting facilities during wet weather.
(9) A schedule for the construction and ongoing maintenance of all required erosion and sediment control facilities.
(10) Identification of discharge points where concentrated runoff occurs.
(C) Review and approval.
(1) Erosion control plans shall be submitted for review to the City Engineer/Public Works Director concurrent with the grading permit application or with submittal of the grading plans, unless otherwise waived by the City Engineer/Public Works Director.
(2) All erosion control plans submitted for review shalt be accompanied by the following: payment of the plan-checking fees, the required number of copies of the erosion control plan and required copies of the bond estimate for security.
