Explanation
The bill requires the Department of Transportation (DOT) to develop
a schedule and fund the construction of certain noise barriers.
According to DOT, the bill's requirements include funding noise
barriers at 37 locations at a cost of more than $320 million over a 15-20
year period. Of the total cost, DOT expects the state portion to be at least
$83 million, with the remaining costs eligible for federal reimbursement.
The bill's noise barrier projects are not included in the department's
current capital plan.
The Out Years
The annualized ongoing fiscal impact identified above would
continue into the future subject to the timing of the noise barrier
construction projects over the next 15-20 years. To the extent the state’s
costs are financed using bonded dollars, the long-term cost would
increase due to interest costs and be spread out for up to 20 years after
the final barrier was installed.
