Williams,Jr., City Manager <br /> Bruce A. McNabb,P. E.,Director of Public Works <br /> Stephen P. Swanson,P. E., City Engineer�-��� <br /> !.l� <br /> SUBJECT: Street Reconstruction <br /> City Project 9824 <br /> The Street Reconstruction Program involves constructing new pavement in curbed or <br /> non-curbed streets having existing pavement with no useful life remaining. In the case of curbed <br /> streets, they have, over the course of their lifetime, received multiple layers of surface treatments <br /> and/or overlays. Each succeeding layer has reduced the available gutter depth by the thickness of <br /> the surface treatment or overlay. The available gutter depth on most of these streets has become <br /> two inches or less, such that the curb has lost most of its functional purposes (i.e. drainage <br /> control, access control, pavement edge delineation, delineation of non-vehicular travelways, <br /> aesthetics, roadside management, etc.). In the case of non-curbed streets, the existing pavement <br /> has become badly deteriorated through age and use and can no longer be cost effectively <br /> maintained by the City's street crews. <br /> These streets are a constant source of citizen complaints because of their poor condition, <br /> which typically precludes routine maintenance practices from being cost effective. The City has <br /> performed limited maintenance work as a temporary relief to roadway users. This year's program <br /> will reconstruct approximately 1.65 centerline miles of street. The miles of City streets needing to <br /> be reconstructed is estimated to be 42.5 miles based on the Pavement Management System report <br /> for needs through 1998. A listing of the streets in this year's program is attached for your <br /> information. <br />
