The Mohave County Flood Control District has developed this FEMA Map Viewer in order to provide the public with the best information available about their property and the associated flood risk. You may access the FEMA Map Viewer from several locations throughout our website. When you click on the link, the first screen is a short Disclaimer. Please take the time to read the full Disclaimer, before clicking I Agree. Welcome to the FEMA Map Viewer!
On the left side of the screen is the Menu. The menu lists the five components of the viewer: Layer Visibility Search Parcels/TRS Tools Navigation Geolocation The Menu window can be hidden by clicking here The width of the Menu window can also be resized by placing your mouse along this line until you see a symbol like this: This document will now take you through each Component as well as some other features of the FEMA Map Viewer.
The Layer Visibility Component This component allows the user to view several layers at once, as well as change the transparency of each layer. As you check the boxes to turn on or off the layers, you will become familiar with how they look and can then customize the Viewer to your needs when you open it. Please note that some layers are only visible as you zoom in. Sometimes you have to zoom out in order to select or deselect layers. The layers that open by default are Imagery Background, Labels, Roads and Current FEMA Data. To go to another Component, click on the title.
The Search Parcels/TRS Component
This component allows the user to search for parcels in several different
ways: Owner Name, Address, APN (Assessor’s Parcel Number) and
Township-Range-Section.
The default search is by Address. Click on the Select Search Type
dropdown to choose another way to search.
Click this box to type in your search criteria. You must have a complete
APN or Township Range and Section to use either of those search types.
However, when using the name or address search types, you can use a
partial name or address.
For example, if you only have the street number, your results would look like this.
If you do not see the record you are searching for in the list
of records displayed, often there are more records available
below what is able to be seen in the small window.
To locate the additional search results, place your cursor over
the search results displayed and use the scroll feature of your
mouse to scroll down to the record you are looking for. If you
do not have a scroll feature on your mouse, you can left click
anywhere in the records showing and use the down arrow key
on your keyboard.
When you have found the desired record, left click anywhere
in the row of that record and the Viewer will Zoom to that
parcel.
