How is this feasible? Redeveloping land in SoCal would be cost prohibitive. Even in the area of Long Beach they were using as an illustration, the average house price is at least $500,000. It's part of the reason the last major freeway to be built, the 105 had to be scaled back from going to from LAX to Riverside (Like 60-70 miles) to ending in Norwalk, (less than 20 miles). And that was in the late 60's to early 70's when that was being planned.
