Stormwater Pollution Prevention Plan Narrative A Stormwater Pollution Prevention Plan (SWPPP) has been prepared as part of the construction Stormwater permit requirements.The site is 0.29 acres in size and is located at 215 Dorn Ave, Everett,WA 98208, with tax parcel number 392500001700.Two new duplex structures and driving access are proposed to be constructed. The limits of disturbance will be 12,000+SF with greater than 5,000 sf of impervious surface triggering minimum requirements#1-9. Limited grading will occur on-site. The purpose of the SWPPP is to describe all temporary and permanent erosion and sediment control (TESC) measures, pollution prevention measures, inspection/monitoring activities, and recordkeeping that will be implemented during the proposed project.This narrative is to be considered a "living document."This project's Certified Erosion and Sediment Control Specialist is to amend this document as needed during construction. Applications of these elements are shown on the TESC Plan Sheet.The specific elements included in the SWPPP are: Element#1: Mark Clearing Limits Prior to the beginning of land disturbing activities,the clearing limits are defined on the TESC plan.
