CITY OF COLTON AGENDA REPORT For City Council Meeting of APRIL 21, 1998 TO: HONORABLE MAYOR & CITY COkV APPROVAL: HENRY GARCIA, CITY MANAGEFP FROM: JOHN C. HUTTON, PUBLIC WORKS DIRECTOR' SUBJECT: PROPOSED STREET PAVING PROGRAM FOR FISCAL YEAR 1998199 DATE: APRIL 13, 1998 BACKGROUND: In 1992, the City employed the firm of "Infrastructure Management Services" (IMS) to perform a pavement management study; this program was both State -mandated and Council approved. Annually the City reviews and approves, by resolution, a 5 Year Capital Improvement Program and a 20 Year Transportation Plan in conjunction with State & Federal guidelines and regulations, and S.A.N.B.A.G. requirements. Included in this program are Gas Tax funds and Measure I funds, which can be used for any qualifying expenditures of street improvement within the City, and Host City Fees, which are limited to maintaining those streets that are designated as track routes to and from the County dump site,. or as may be identified as an applicable project under the County/City approved Host City Fees M. 0. U. DISCUSSION Based upon a combined review of both the condition, rate (as assigned via the IMS program) and a visual field review performed by the Public Works Department, a spread sheet report has been created, depicting streets in the City which have been selected for rehabilitation, in order to maintain a minimum level of serviceability for the public at large. This report (see _ attached! _Exhibit A) has .been . generated, as a suggestion, for possible use of surplus funds available from the various funding sources. The streets selected have been grouped into Grids, by location and/or source funding eligibility. In determining which streets would be selected for rehabilitation, the following criteria were used: Field Review - Streets with an unusually high reporting of potholes and streets noted by department employees (via Field Review) to be in exceptionally bad condition. An IMS computerized rating of 70 or less Ratings are taken from the IMS ranking list generated in 1992; aging decreases these rankings by approximately 5% for each year. This computes to an "aged" ranking of 49 or less. A ranking less than 59 is well into the range where rehabilitation is required, and the possibility of total reconstruction (replacement or revitalizing of sub -base, base and surface treatment) is warranted if not required. Information regarding the Pavement Pfiofity Report is attached (Exhibit B). This report is used as a guide and indicator of which streets need to be visually reviewed, the likely physical condition which may be expected, and the presumable cause of any problems which may be present. The Pavement Condition - Detailed Report indicates contributing elements which have been factored into the resultant pavement rating (attached Exhibit C). Page 1 of 2 Item # 19
