Item C: Review of Implementation of Street Bond Measure

Home Browse Search

EXECUTIVE SUMMARY — ( continued) New construction techniques such as in -place recycling (also known as in -place cement treated base) which strengthens existing roadbed materials for reuse have been successfully used in place of conventional reconstruction techniques resulting in substantial cost savings. • There has been an increase in inventory of improved streets through capital improvement projects (CIP), privately engineered public improvements (PEPI) and jurisdictional transfers. Overall, even though the backlog figure declined in 2012, the current level of funding -- including the two bond measures -- is insufficient to stabilize the backlog long term. Annually, a number of streets needing a less expensive treatment are falling into a more costly treatment category due to lack of funding to repair them. It is also important to note that the backlog estimate is limited to improved asphalt streets. It does not take into account the repair needs for concrete streets, unimproved streets, sidewalks, off - street shared -used paths, or other elements of the transportation system. The 2012 report uses three funding scenarios to project treatment needs and costs over a 10 -year period. The analyses for all three scenarios use costs updated by Engineering in 2011 and are adjusted to include a 2% inflation factor. Following is a summary of the analyses: • Maintaining the current level of funding, including the 2008 and 2012 bond measures, results in a total projected backlog of $238 million in 10 years. Last year, prior to approval of the 2012 bond, the projected 10 -year backlog was $264 million. Increasing the funding level to $12 million annually would prevent arterials and collectors currently from falling into the reconstruct range and eliminate the reconstruct backlog for arterial and collector streets in 10 years. Prior to this year's report, these results required a funding level of $15 million annually. Increasing the funding level to $19 million annually would prevent any street from falling into the reconstruct range and eliminate the total reconstruct backlog in 10 years. Prior to this year's report, these results required a funding level of $18 million annually. Due to the substantial and increasing backlog in Residential treatment needs (residential streets account for approximately 64% (lane miles) of the system) additional funding is required to achieve the same results as in previous years. 2
