PMP Funding Annual Needs: Over the past 3 — 4 years, the construction industry has seen the same high levels of inflation as others, generally resulting in costs increasing 25 to 40-percent. For comparison, in 2021 Staff estimated a $200,000/mile cost for a typical overlay, whereas in 2024 the same project is estimated at $300,000/mile. The City has approximately 189 miles of public streets, including existing gravel roads. During the 60-year design life, a street is anticipated to require 2 overlays and 1 reconstruction. In 2024 construction dollars, the City estimates that on a typical street the average overlay costs $300,000 per mile, and the average reconstruction costs $850,000 per mile. Please note the reconstruction cost is averaged over all the different project types the City uses, i.e. full reconstruction, full -depth reclamation, stabilized full -depth reclamation, and reclamation rehabilitation. For the typical neighborhood street, the life cycle cost per mile = 2 x $300,000 + $850,000 = $1,450,000 / mi. / 60yrs. All neighborhood streets combined cost 152.73 mi. x $1,450,000 / mi. / 60 yrs. = $221,458,500 / 60 yrs. That makes the annual need for neighborhood streets $3,690,975 in today's dollars. This does not account for making up ground on existing streets which may require reconstruction ahead of the assumed life cycle. For typical MSA collector streets, the streets have a thicker pavement section and usually extra width from parking lanes adding approximately 20-percent to per mile costs. This makes the cost per mile / 60 years equal to $1,740,000. For all MSA streets combined, the cost = 33.81 miles x $1,740,000 / mi. / 60yrs. = $58,829,400 / 60yrs. That makes the annual need for MSA streets $980,490 in today's dollars. This is approximately the amount of MSA funding the City receives, so we can say in general the MSA street funding needs are close to being met. Recommendation: This case is intended to update the Public Works Committee on the status of the Pavement Management Program. Staff does not have a recommendation at this time. Outcome/Action: This case is to update the Public Works Committee on the status of the Pavement Management Program. Staff is not requesting action, but would welcome any direction given by the Public Works Committee based on the update.
