http://www.floodsmart.gov (make sure it is the .gov extension and not the .com extrention) provide good feed back on the need of flood insurance which I did not always find listed accurately on the MLS.
One last stop I would do is visit the most local government site you can get for plot maps and tax infomation. Sometimes those sites will also confirm the flood plan in the area. Here is an example for Newport Beach governmental site: http://www.city.newport-beach.ca.us/
hope this helps,
Additionally, if you have a more specific request, I have some properties and other portions of Pelican, Crystal Cove, etc. that are low-altitude, high-resolution images shot approximately 8 months ago from a UAV. And, I have four or five aerial photographs of the general Newport Coast preserves that are about 2 years old.
