discharges to Pigeon Creek#1,as does runoff from your lot across the street. Car washing in these areas, with the subsequent discharge of wash water to the creek, is a violation of City ordinance. Also,the portion of your site north of the building appears to drain to a catch basin at the far northeast corner of the site, which may discharge to either the sanitary sewer or to Pigeon Creek#1. Until the discharge location of this catch basin is determined not to be Pigeon Creek#1,cars must not be washed north of the building. As soon as we have completed the additional investigation of your drainage system, I will call you to discuss the results. If you have any questions, please feel free to call me at 425-257-8885. Thank you. Sincerely-, j . e ' �'- an, PE Ategngineer Attachment CC: Clair Olivers, Public Works Director Dan Mathias, PE, Principal Engineer Mike Papa, Engineering Technician
