Can you post a copy of the FIRM panel where this is occuring?  Have you used the FIRMette tool at FEMA's website?

 FIRM PANEL  0809 OF 4350 FIRM ZONE D  dated 7-19-01
I am not familiar with the FIRMette tool

Thnak you

That map was revised effective Sept 30, 2005.  Looks like a major update to DFIRM standards.  There are no Zone D on that map any longer.

Use the link I provided above to generate your online Firm panel.  Once you have the FIRM map follow the instructions to create a FIRMette of the location you are looking at.

Note that this area has alluvial fan type flooding which is an extremely hazardous flooding condition.

Digital information for this map is readily available from FEMA.  I can help point you towards who you would need to speak to in order to get this.

I just printed  a portion of it.
It is Zone D exactly where I want to
change it to Zone X.

Please provide contact to get digital map. I have all the studies that were developed and submitted to FEMA to
establish the latest map designation.

queque-

If you go to to the FEMA map store online, or follow the link that Callin provided, you can indeed lookup your location and find that there is an updated map for your area.  You are not using the current map.  However, contrary to Callin's statement, there ARE Zone D areas on the map still.  I do not know the precise location of your site.

Here is an example of a Firmette I created from the map you cited:

I assume that is what is referred to as a digital map?
I created a firmette. Thanks to all of you.
 

Sorry, I didn't see those Zone D areas.  I looked too fast.

I am having trouble getting in contact with a friend over at FEMA Region 9.  I will let you know when I do. By digital map, I meant the GIS data that was used to construct that DFIRM panel.
