E N HILLS. MEMORANDUM Item 1.0 DATE: September 21, 2009 TO: Mayor and City Council Ron Moorse, City Administrator FROM: Greg Hoag, Public Works Director SUBJECT: Update on erosion correction project on the Old City Hall Trail BACKGROUND In July of this year the City Council authorized an Engineering Services agreement with Bolton and Menk Inc. for survey and engineering services to correct an erosion issue on the property at 4504 Keithson Drive adjacent to the Old City Hall trail. Bolton and Menk Inc. completed a survey of the area the first week of August. On August 1 lth Public Works Director, Greg Hoag and Marcus Thomas, Bolton and Menk Inc. met onsite with the resident, Ron Nelson to discuss the results of the survey and to preliminarily discuss potential solutions for resolving the erosion issue. Marcus Thomas then took the information gathered from the meeting as well as the survey and came up with three possible approaches to eliminate the erosion problems on Mr. Nelson's property. Attachment A is a memorandum from Marcus Thomas explaining these approaches. While both options 2 and 3 can effectively resolve the drainage and erosion issue, Bolton and Menk Inc. is recommending to staff that option 2 be considered as it is a more cost effective option. On August 26th we again met onsite with Mr. Nelson to discuss these three possible solutions and the Engineer's recommendation to the City. Mr. Nelson has provided the City with a letter(Attachment B) dated September 14 stating his support for option 3. COUNCIL DIRECTION REQUESTED Staff and Bolton and Menk Inc. are seeking City Council discussion and direction on which option to continue forward in the design process for project completion to resolve the drainage and erosion issue. Marcus Thomas and Mr. Nelson will be present at the Work Session for questions and discussion.
