NOP - Notice of Preperation

Document Description
NOTE: Lead Agency changed from Caltrans Planning to Caltrans Dist. 7. The proposed project, depending on the results of a thorough environmental analysis of all possible transportation improvements during the NEPA/CEQA process, may include, but not be limited to: surface and subsurface highway/freeway construction, heavy rail and bus/light rail systems, local street upgrades, traffic management systems and a no build alternative. There currently is a gap in the I-710 corridor, for a distance of ~4.5 miles (7.2km), which extends between Valley Boulevard to the south and Del Mar Boulevard to the north. As originally identified in the April 13, 1998 Record of Decision for the Meridian Variation alignment, this gap contributes to congestion on local streets and the regional freeway system. The objective of this project is to relieve congestion and improve mobility within the study area.
