PUBL/C /�YOR/�fS MEMORANDUM TO: File FROM: Dan Mathia DATE: December 21, 1994 �JBJECT: IVielsen Bros. Flooding Program Frank and (Pete?) Nielsen both called me the afternoon of December 19, 1994 to discuss the flooding problem at Nielsen Bros. Carpet at SE Everett Mall Way. According to the Nielsens they replaced 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 Caz site to the east. T'he Nielse►�s wanted to know who would be liable for damages if the Classic .^.ar site is flcwded again. I responded that liability is somethin�� v��$ be sorted out latcr by attorneys. I told the Nielsens that I would compare the r e capacities uf the 30 inch culvert and 48 inch corrugated metal culvert, confirm site conditions with Dan IIall and look at rainfall records to determine if 30 inch culvert is a p:ublem. The Nielsen�s wanted to know what could be done right now. I suggested construcdng a sand bag wall and we both agreed that pumping wasn't feasible. Don Iiall came into my office after I hung up from the Nielsen's. He verified that the 30 inch culvert was flowing !'ull. He stated that the 48 inch was approximately 9" from flowing full. He also stated that there was 3' to 4' of free6oard remaining before water flooded over the wall to the Classic Cu site. Don confirmed that the water level wasn't a maintenance problem, but he stated that the creek level wasn't rising during tiie hour he was on-site. pA:IMahm�lY11M1
