(A) Plan required.
(1) Unless waived by the City Engineer, all work requiring a grading permit shall be required to have an approved Erosion Control Plan. If the requirement for an Erosion Control Plan has been waived, the City Engineer may still require the installation of temporary and/or permanent erosion control devices or methods to control erosion and provide safety during grading.
(2) No activity authorized under a grading permit shall be conducted between October 1 and May 31 unless an Erosion Control Plan has been approved or the City Engineer has waived the requirement for an Erosion Control Plan.
(3) The requirement for an Erosion Control Plan may be waived for grading on single residential lot projects, provided that an erosion control system, approved by the City Engineer, is installed, placed, planted or constructed before October 1.
(4) An Erosion Control Plan is required for a project if the City Engineer determines that erosion or sediment discharge from the project could adversely affect adjacent properties.
(5) An approved Erosion Control Plan from the previous year shall be updated and submitted for approval, if necessary, prior to October 1 to reflect any changed conditions where the grading or other land disturbance activity is continuing. Updating of the Erosion Control Plan will also be required for phases of construction not covered by any previously approved Erosion Control Plan.
(6) All Erosion Control Plans must be approved and erosion control devices installed and certified and inspected as being properly constructed by the civil engineer. 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 protective measures, including desiltation basins or other temporary drainage or control measures or both, necessary to implement and satisfy the applicable requirements and standards set forth in § 15.36.280 and necessary to protect 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 for the Public Works Department - Land Development Division);
(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 by October 1;
(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 concurrent with the grading permit application or with submittal of the grading plans, unless otherwise waived by the City Engineer.
(2) All Erosion Control Plans submitted for review shall be accompanied by the following: payment of the plan-checking fees, two blueline copies of the Erosion Control Plan and two copies of the bond estimate for security.
(3) No Erosion Control Plan shall be approved unless the Erosion Control Plan complies and implements all applicable standards and requirements set forth in this section and § 15.36.280.
