PUBL/C WO/q/ffS MEMORANDUM TO: File FROM: Dan Mathia � DATE: December 21, 1994 SUBJECT: Nielsen Bros. Flooding Program ��7�� �� Frank and (Pete?) Nielsen both called me the afternoon of December 19, 1994 to discuss the flooding problem a! Nielsen Bros. Carpet at SE Everett Mall Way. According to the Nielsens they replar,ed their crushed culvert with a new 48 inch diameter corrugated metal culvert. The Nielsen's stated that the 30 inch culvert under SE Everett Mall Way was flowing full and their 48 inch culvert was approximately 12 inches from flowing full. They stated that the water level in North Creek was continuing to rise and was 24 inches from overflowing the wall onto the Classic Car site to the east. The Nielsenls wanted to know who would be liable for damages if the Classic Car site is flooded again. I responded that liability is somethin� t� t�v�� be sorted out later by attorneys. I told the Nielsens that I would compare the r�e�iwve capacities of the 30 inch culvert and 48 inch corrugated metal culveR, confirm site conditions with Dan Hall and look at rainfall records to determine if 30 inch culvert is a problem. The Nielsen�s wanted to know what could be done right now. I suggested constructing a sand bag wall and we both agreed that pumping wasn't feasible. Don Hall came into my office after I hung up from tlie Nielsen's. He verified that the 30 inch culvert was flowing full. He stated that the 48 inch was approximately 9" from flowing full. He also stated that there was 3' to 4' of freeboard remaining before water flooded over the wall ro the Classic Car site. Don confinned that the water I, vel wasn't a maintenance problem, but he stated that the creek levet wasn't rising during the hour he was on-site. nnt:u�ae7�xivtiron
