HomeMy WebLinkAbout10/30/19901 City Council Minutes Tuesday, October 30, 1990 - 7:00 p.m. Page 2 to prioritize recommendations for budget and implementation of a program for structural repair of buildings. He stated that the need to evaluate the ability of City -owned buildings to survive an earthquake was discussed last spring at a Managment meeting. The Public Works Department was directed to seek a professional consulting firm to review the principle City -owned buildings and to make recommendations regarding their condition and need for repair. Following the Purchasing Manual Procedures, H.J. Degenkolb Associates, Engineers, was hired to conduct the review. Mr. Peterson then introduced the consultant, MaryAnn Phipps, representing Degenkolb Associates, who gave a slide presentation and reviewed those structural buildings in need of repair. She reviewed the 'low risks' to life safety being those buildings of the Jack House, Senior Center, Art Center and Fire Station No. 3. Buildings of 'moderate risk' to life safety are the Black Adobe, Recreation Administration Building, Recreation Center, Fire Station No. 2 and City Hall. There were two buildings identified as 'high risk' to life safety; the County Historical Museum and the Public Works Office at 955 Morro Street. After discussion, moved by Roalman /Dunin (3 -0 -2, Councilmembers Pinard and Rappa absent) to: 1) receive the report, 2) direct staff to implement the non- structural repairs through individual department budgets, and 3) direct the City Administrative Officer to establish a staff committee to prioritize recommendations for budget and implementation of a program for structural repair of the buildings. Notion carried unanimously. 1. FLOOD MANAGEMENT UPDATE (File No. 592) Council held a public hearing to consider the Flood Management Report update and Policy Revision. Dave Romero, Public Works Director, reviewed the agenda report with the recommendation that Council receive the staff report and set a public hearing to receive testimony regarding flood policy and basic approaches to be followed for flood protection. He stated that in 1983, the City prepared the Flood Management Report and the Flood Management Policy. The Council made certain environmental findings and adopted the Flood Management Policy standards and action plan. Many of those projects had been completed, others were in various stages of design, and some delayed for other reasons. The purpose of the report was to provide an update of waterway improvement work conducted since 1983, and to initiate a dialogue leading to the adoption of a new action plan to protect against flood damage. It was staff's recommendation to construct an upstream detention dam together with providing minimal widening on the major creeks. The advantages of this would be: 1) The upstream detention dam would provide the most cost effective solution, 375 376 City Council Minutes Page 3 Tuesday, October 30, 1990 - 7:00 p.m. 2) Riparian habitat upstream of the City would be purchased and developed for park purposes, 3) San Luis Creek, upstream of the confluence, would not have to be widened, thus preserving existing habitat, 4) San Luis Creek downstream of the confluence would be widened by a lesser amount than under the current plan, thus minimizing damage to the riparian habitat and minimizing cost, 5) A trail system could be developed in conjunction with the widening below the confluence, 6) Citizens within the community would be.protected when the improvements were completed, and, 7) The upstream detention dam could be managed so as to retain some water at the end of the rainy season that could then be released during the summer to enhance the creek habitat. The disadvantages would be: 1) Acquisition of property and development of the dam, which would require a lump sum expenditure of 2.2 million, 2) Widening of the San Luis Creek below the confluence would be required, 3) Construction of the dam and widening below the confluence would create environmental damage which would require some time to completely mitigate, 4) There is always some risk of dam failure, though the dam would be emppty or would retain a small amount of water most of the time. Wayne Peterson, City Engineer, explained details of the analysis for the various solutions considered. He pointed out advantages and disadvantages of the various alternatives. He explained for Mr. Romero that the staff would be recommending the following at the public hearing: 1) Reaffirm the-Flood Managment Policy and, 2) Direct staff to pursue Flood Control studies and reports with the following as the basic approaches: a) Development of a detention dam upstream of the City on San Luis Creek following staff concept of restricting all flows greater than a ten year storm, b) Eliminate "tight spots" in each of the City's waterways so as to achieve a balanced design which would handle design flows, 1 City Council Minutes Tuesday, October 30, 1990 - 7:00 p.m. Page 4 C) Widen San Luis Creek from the confluence toothe southerly City limits to handle design flows. This widening would be accomplished as opportunities present themselves, based on an adopted creek widening plan line, and creek widening policy. Most of the acquisition and widening would be conducted as properties were developed, and d) Incorporate in all waterway improvements where feasible, trails, retention of riperian habitat, and other amenities to create an attractive environment. Mayor Dunin requested that when this item went to hearing, the report should indicate that the primary purpose for the plan is flood control and protection, with the secondary goal, preserve the natural beauty and character of the creek system. Councilman Roalman questioned how many structures would be threatened by seasonal flood and what the cost ratio would be to flood proof those structures as opposed to construction of a dam. After discussion, moved by Dunin / Roalman (3 -0 -2, Councilmembers Pinard and Rappa absent) to approve the staff recommendation to set a public hearing to receive testimony regarding flood policy and the basic approaches to be followed for flood protection, including Councilman Roalman's request to direct staff to determine the number of structures that are vulnerable to flooding and identify the cost associated with `flood proofing' them. Motion carried unanimously. -------------- —mm ---------- --------- ------- --- ------ ----------------------- COMMUNICATIONs Vice - Mayor Reiss expressed disappointment in the letter appearing in tonight's newspaper from one of the Councilmembers and her stand on a previous action taken by the City Council. 9:40 p.m., there being no further business to come before the City Council, Mayor Dunin adjourned the meeting to Tuesday, November 6, 1990, at 4:00 p.m. for Closed Session at the City /County Library to discuss litigation negotiations with Interwest Incorporated.
