The Los Osos Valley Road Interchange (LOVR) project began construction in the Fall of 2014
and was completed in 2016. This landscaping project is a required environmental mitigation of
the overall Los Osos Valley Road Interchange Project and is a joint effort between Caltrans and
the City. This project was designed by Oasis Associates Inc. under the direction of the City and
Caltrans. To establish the specific roles and responsibilities of Caltran s and the City during
project implementation, a Cooperative Agreement (Agreement 05 -0312) has been completed by
Caltrans and City staff and was approved by Council on July 12, 2016.
Landscaping will be provided along both sides of the new bridge as well as the planting area
adjacent to the on- and off-ramps from U.S. 101. Existing trees shall remain and be protected
during construction. New plantings will include trees and shrubs within new mulched areas. All
new plantings shall be monitored and mainta ined for a required three-year establishment period.
New planting will be irrigated with recycled water.
