Box 196650 Anchorage, Alaska 99519-6650 Phone 343-7904 RECEIVED SEP a 4 2001 MUNICIPALITY OF ANCHORAGE COMMUNITY PLANNING & DEVELOPMENT Re: S-10733 Hoffbeck S/D, Lots 1 & 2, Seasonal Water Monitoring Dear Jim Cross: The above referenced property has been monitored since April 2001 for seasonal high water readings for the above subdivision approval. The single test hole is 16 feet deep and after monitoring through the spring and summer months only one inch of water was ever found in the monitor tube. The soil around the monitoring tube had settled some and maybe spring run-off might have been the contributing factor, the water only lasted for a week in May, then it was gone. This water table will not impact the design of a system due to the good sandy material above as stated in the soils logs submitted previously for the subdivision plat. This is the final report need for the subdivision agreement unless directed otherwise. If you have any questions concerning this inspection please call me at 345-3377. Sincerely, Michael N.
