359 OLR Bill Analysis sSB 414 AN ACT CONCERNING VEGETATION MANAGEMENT GUIDELINES BY THE DEPARTMENT OF TRANSPORTATION.

SUMMARY This bill delays, from July 1, 2025, to October 1, 2026, the due date for the UConn Department of Natural Resources and the Environment’s final report on its study of carbon sequestration by trees and other vegetation along highways and other areas in Connecticut.

(Under current law, its interim report was due by January 1, 2025, but, in practice, the department published that report on February 1, 2026.) Along with the final report, the bill also requires the UConn department to submit its study results and any related recommendations to the Department of Transportation (DOT), which is in addition to the Transportation and Environment committees as current law requires.

Relatedly, the bill requires the DOT commissioner, by February 1, 2027, to consider the results of UConn’s study and determine whether DOT’s vegetation management guidelines need to be accordingly revised.

If the commissioner determines that the guidelines do not need to be revised, he must report to the Transportation and Environment committees explaining why.

Alternatively, if he revises the guidelines based on UConn’s study, he must submit them to these legislative committees and the committees must hold a joint public hearing for the commissioner to present on the revised guidelines.

The bill also makes technical and conforming changes, including deleting obsolete language.

EFFECTIVE DATE:

July 1, 2026, except the DOT commissioner and legislative committee requirement provisions are effective October 1, 2026.
