9.4.6 Erosion Control

An application for a SDAP for grading shall include a Construction SWPPP in accordance with Volume II, Chapter 2.

  1. Applicant’s Responsibility – Temporary erosion and sedimentation control BMPs shall be installed prior to any clearing and/or grading taking place. The applicant is responsible at all times for the installation and maintenance of erosion and sedimentation control facilities, as stated under Minimum Requirement #2, Element #12.

    1. Development projects shall be phased to the maximum degree practicable and shall take into account seasonal work limitations.

    2. The Permittee must require construction site operators to maintain, and repair as needed, all sediment and erosion control BMPs to ensure continued performance of their intended function.

    3. The Permittee must require construction site operators to periodically inspect their sites. Site inspections shall be conducted per the requirements of Volume II, Chapter 2.

    4. The Permittee must require construction site operators to maintain, update and implement their SWPPP. Permittees shall require construction site operators to modify their SWPPP whenever there is a change in design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state.

  1. Emergency Contact Person – An emergency contact person having the means and the authority to institute emergency erosion and sedimentation control measures shall be available at all times until construction is completed, on a 24‑hour-per-day basis. The name, address and 24‑hour telephone number(s) for the emergency contact person shall be listed with DCD. In the event that Kitsap County becomes aware of an emergency condition on the project site and is unable to contact the designated emergency contact person, or deems that the response to the emergency situation is inadequate, Kitsap County may enter the project site and perform any emergency work deemed necessary to protect life and limb, property, or adjacent public ways, critical areas or drainage courses. The project owner will be required to reimburse Kitsap County for all related costs incurred by Kitsap County for such emergency work.

  2. Sealing the Surface – At the end of each day's work, the contractor must grade all areas to drain.

  3. Revegetation – Unless the approved plan provides otherwise, all cleared areas shall be seeded as soon as possible, or receive some other acceptable surface stabilization treatment in accordance with Volume II, Chapter 2.
