BACKGROUND: The recent storm activity which occurred in December 2010 between the dates of Tuesday, December 21 through Thursday, December 23, 2010 caused significant damage to several City of Riverside Public Utilities sites. A portion of Chicago Avenue just northerly of Central Avenue was washed out, requiring the replacement of a portion of the existing 18-inch and 12-inch segments of water main to be replaced. At the John W. North Treatment Plant, the slope of an adjacent hillside failed, bringing mud and debris into the treatment plant site and building. Several locations along the Riverside Canal suffered flood- related damage due to run-off water eroding the canal sidewalls as it drained into the canal, resulting in failure of the concrete canal lining. In addition, run-off into the canal introduced significant volumes of silt, mud, trash, and vegetative debris which need to be removed. Erosion damage by drai-ling water occurred at the following sites in San Bernardino: NPDES Pond and Gage 27-1 Well; and Riverside Golf Course, Whitegates I and li reservoirs, and the First St. Well in Riverside. At Mockingbird Canyon Lake, the heavy rains introduced significant amounts of sand and silt into the lake which covered the openings of the outlet drainage structure. Repairs have been completed on the Chicago/Centrai 18-inch and 12-inch water mains in conjunction with Public Works' effod:s to repair the storm drain and street. Repairs at the other Public Utility Water sites are underway. Ar estimate of the expenditures to restore these sites/facilities is presented in the table below. Section 1202(b) of the City Charter provides the following: "(A] purchase, or acquisition, construction, extension, enlargement, diminution or curtailment may be made without prior approval . . . (2) if there is an urgent necessity to preserve life, health or property (i) as determined by the Director of Public Utilities or, (ii) if the amount exceeds $100,000 by the Director of Public Utilities and the City Manager. As soon as practicable thereafter, the Director of Public Utilities shall take the matter under Section 1202(b)(2) to the Board of Public Utilities for ratification." Here, the City Manager and the Public Utilities General Manager (referred to in the Charter as the "director") approved the emergency work in order to preserve life, health and property from the storm-related damage, and now seek Board approval for such expenditure.
