1 Dean Morris said if there was some concern regarding the anchoring of structures, a structural engineer could be added to the team to verify each situation and submit a recommenation and certification e for each building. Ann Ramp, 918 Lorane Highway, co-chairman Crest Drive Citizens Associ- ation, said the group was interested in hillside development in that area. She noted a great deal of information had come from working with the Treehouse people. She thanked Dr. Orr, Dan Knapp, the development team, Bert Teitzel, and the City staff for their assistance in consi- dering the various problems and taking into account the concerns of the Citizens Association. She felt the Treehouse officials wanted to do a good job; and commended them for their approach to this develop- ment project. However, she noted there was a general concern for all development on the hillside, not just Treehouse PUD. The geological problems raised in this particular PUD are very real. She noted there would be problems with water drainage in the Amazon with the amount of building that is to be considered for the South Hills area. She hoped Council would addresss this problem very soon. Mr. Saul said the purpose of the conditions listed in the South Hills Study was to flag them as an early-warning system that special concerns were to be accounted for and special procedures used as applications were reviewed. Those statements were not to be construed that development was not possible in that area. He noted also the Amazon Channel was a Corps of Engineer facility. The Corps is now conducting a study regarding improvement of the channel. He noted that channel services the entire southeast and central area of - Eugene, and the effects cannot be limited just to the Treehouse PUD itself. Bert Teitzel, City Engineer, and Mick Nolte, Building Inspector, were available to answer questions. Mr. Delay wondered if staff had any perception as to how the standards used (ORS Procedures) for footing drainage compared to those used, for instance, in California where major slippage and destruction of homes occurred. Mr. Saul said the standards used as set forth in the geological report are not state statute mandated standards. These standards recommended are the best known within the state of the art of engineering design. He did not know if those were similar to standards used in other parts of the country, such as in California. He said one of the chief problems in such areas where major slippage occurred was that no standards were imposed. In answering a question from Ms. Smith, Mr. Saul said whether or not a structural engineer was added to the design team was within the discretion of City Council. He noted recommendations that special engineering footings be required were outlined in Condition No.7. He also noted conditions outlined already required a landscape engineer for each building site. e 6/12/78--4 ~1~ I
