Most
Skagit County projects are created from County created data sets or from data received
from other agencies. Skagit County shall not supply any data that the County has received from other agencies
due to license agreements and data currency issues. Therefore, we
have provided you with this page to help direct you to the additional
data sources we use. Many of our data sets are derived from these
data sources and, therefore, do not qualify as a Skagit County data set. For example, most of our Critical Areas data
sets are derived from other sources to produce steep slopes, riparian,
and habitat.
The
following are links to data sets from other agencies. We have prepared
a comprehensive list of links to these agencies to help you find and
acquire additional data. Most agencies require written license agreements
before you can obtain their GIS data sets. Additionally, they will
likely require a fee to process your request. The following links
will open in a new browser window. Access Skagit County and the GIS department are not responsible for content

Federal Emergency Management Agency:
FEMA has created digital Q3 flood data, which contain only certain
features from the existing FIRM hardcopy. Q3 vector data are contained
in one single countywide file, including all incorporated and unincorporated
areas of a county. For more information on Q3 data, please
click here. Along with the Q3 data, FEMA now provides Flood
Insurance Rate Maps (FIRM) over the internet. However, these are
only scanned versions of the existing FIRM maps and not digital
FIRM maps (DFIRM). FEMA’s web site is fairly well designed
and allows you to print (8.5x11” or 11x17”) a scale version
of the selected area of the FIRM panel you choose. To view this

has aerial imagery available for much of the State of Washington as
part of their aerial photography program to support agricultural lands
and natural resource conservation. The photography is 1 meter leaf-on
imagery and is not cloud-free so the ground might be obscured. To

- Washington State Department Of Fish and Wildlife: The Washington Department of Fish
and Wildlife (WDFW) maintains a number of GIS databases that contain
information on important fish and wildlife species. This includes
