Description:

Abstract: This dataset describes the riparian extent of the Alexander Valley reach of the Russian River in 2000. The Alexander Valley Reach extent is defined by the Jimtown Bridge and Cloverdale, Sonoma Co. Riparian habitat is defined as the river channel and all areas covered by riparian vegetation along the Russian River's "main stem", including the wetted channel, active channel, vegetated channel, channel banks, and that portion of the floodplain between the top of the channel bank and the outer limit of "typical" riparian vegetation. This habitat supports various seral stages of riparian vegetation, and it is assumed to be subject to relatively frequent flooding wherever there are no artificial flood control structures.The mainstem Russian River riparian habitat boundaries were interpreted from Sonoma County Water Agency (SCWA) Aggregate Resources Management (ARM) Plan aerial photos. Some areas of the SCWA aerial photos were missing and limited the extent of the riparian habitat. Aerials from the County of Sonoma Information Systems Department / GIS Group were used to complete the riparian extent.

Purpose:

The intended use of this layer is to support watershed analysis and planning

 

Supplemental Information:

The Aggregate Resources Management (ARM) Plan aerial photos provided imagery coverage of the mainstem Russian River for photo-interpretation and digitizing riparian extent. Though these aerial photos were not orthogonally rectified, the terrain within the floodplain study area is relatively level and the mapping results are considered acceptable for purposes of natural resources planning.

 

 

The aerials from the County of Sonoma Information Systems Department / GIS Group were corrected to the ground using aerial and ground-based global positioning system (GPS) survey coordinates. The data resolution varies from one-foot resolution or better in urban or incorporated areas and two-foot resolution in forested, mountainous, or other unincorporated areas of the County. These aerials were originally in California Stateplane Zone II, NAD 83 (survey feet) II coordinates and were later reprojected to UTM NAD 83 zone 10N.
