ME140 TO: MAYOR AND CITY COUNCIL It FROM: CLERK -ADMINISTRATOR DATE: DECEMBER 29, 1987 SUBJECT: STREET MAINTENANCE STUDY AND PROGRAM In February of 1984 John Johnson, the City's Consulting Director of Public Works, presented the results of a street maintenance study which was adopted by the City Council. In that study, copy attached, Mr. Johnson provided an evaluation of the condition of the City's streets and recommendations for a five year maintenance program. Although the system used by Mr. Johnson at that time was technically up-to-date and proposed a then currently acceptable program for maintaining streets, the level of knowledge has expanded significantly over the past four years. Many different systems currently exist for evaluating the condition of streets, maintaining an inventory which can be easily updated on an annual basis, and establishing an annual maintenance program. The common denominator for all of these systems is that street maintenance is based upon need identifi-d in an annual inspection. No longer are streets automatically sealcoated or ovorlayed every so many years. The Johnson plan called for a sealcoating program which had each street sealcoated every five years. In some cases this is too frequent and in others not often enough. Our streets wear differently based upon age, sub -base conditions, pavement thickness, drainage, traffic load, and weather conditions. Recently, Public Works Foreman Mike Ulrich and I sat in on a presentation by Dan Boxrud and Richard Moore of Short -Elliott - Hendrickson, Inc. (SEH) on a program they call, "Pavement Manager", copy attached. This program would provide the following, A street pavement evaluation program using IBM data- base software which is provided to the City once the initial study is completed. The program would provide for an evaluation of all City streets analyzing the sub -base and visual inspection of surface condition. Other information that may .be included on the data- base are an inventory of street signs and utilities (water, sanitary sewer and storm sewer). Members of our Public Works crew would be trained to perform the field inspections and update the data- base to allow for an annual updating of the system. Such updating would allow for us to gear our street maintenance efforts toward those streets requiring work rather than those "scheduled" for maintenance.
