According to the controller statement, the estimated cost of keeping the Great Highway will vary depending on which proposal the City moves forward with. Regardless of which proposal moves forward, public resources will need to be allocated for the project. It's important for the City to continue engaging the public on the future of this essential access road to decide which alternative to pursue, all of which vary in design, time and cost.

The City has proposed closing and removing the Great Highway Extension and converting it into a park. This is part of a plan to protect the Oceanside Water Pollution Control Plant from the effects of coastal erosion. The City does not need to close any part of the Great Highway to respond to coastal erosion, and has multiple viable options under consideration, with most options preserving full or partial use of the Great Highway Extension. Closure costs us far more in traffic delays, congestion and air pollution by diverting traffic into local neighborhood streets.
