We don't need to shut down the off-road park at the Oceano Dunes. We simply need to stop fighting and reach a compromise. Many parties are involved, and each needs to win something: off-roaders, Mesa residents, endangered species in the creek, Oceano residents, and Chumash sacred sites.
Health needs should come first and need to be met fully. I suggest fencing off the greatest source of PM10 particles (La Grande Tract) during wind season. The creek shouldn't be crossed by vehicles to save the endangered species. At the end of Pier Avenue, cars should only turn north. The beach between Grand Avenue and Pier Avenue can be used for day-use only. This way, Oceano residents get their small piece with a safe, vehicle-free beach south of Pier Avenue and a more livable downtown. Day-use cars should not return through Pier Avenue to avoid tracking out sand and creating PM10.
Day-use cars should exit through the Oceano campground. Parks already has a road in place there, wide and in excellent conditions, through the foredunes onto the beach! This entrance could be used as an alternative to Pier Avenue. Chumash sites must be fenced off and rigorously protected. Off-roaders will need a new southern entrance. Since there is a smaller area to ride in, there should be a smaller number of visitors allowed. As with all other parks in the nation, the use of the park has to be monitored to adjust the number of visitors to its capacity.
