Problem:  Create a map that finds the total length of "Interstate" and "Interstate Ramp" street features that intersect the "Tujunga loamy sand" soil type.

Procedure Log:

Data:  ArcView shapefiles provided by Schenck Forest:

	donut.shp - Donut Shops located within the city limits of Redland, CA (points)
	street.shp - Streets that are located within the city limits of Redland, CA (lines)
	soilscov polygon - Soils that are located within the city limits of Redland, CA (polygons)

	map units for all shapefiles:  meters

Use select by attributes to select soils that are of type "Tujunga loamy sand":

	Target layer:  soilscov polygon
	Method:  Create a new selection
	Selection expression:  "SOIL_DESC" = 'Tujunga loamy sand'
	Result:  9 records selected in soilscov polygon

Use select by attributes to select streets that are classified as 'Interstate' or 'Interstate Ramp':

	Target layer:  street.shp
	Method:  Create a new selection
	Selection expression:  "CLASS_DESC" = 'Interstate' OR "CLASS_DESC" = 'Interstate Ramp'
	Result:  140 records selected in street.shp

Use select by location to select features in the street layer that intersect the soil type classified as "Tujunga loamy sand":

	Selection option:  Select from the currently selected features in
	Target layer:  street.shp
	Selction option:  Intersect
	Selector layer:  soilscov polygon
	Result:  41 records selected in street.shp

Use Open Attribute Table to find the total length of "Interstate" and "Interstate Ramp" street features that intersect the "Tujunga loamy sand" soil type:

	Target layer:  street.shp
	Method:  Open Attribute Table
		Hit "Selected" icon located on bottom of "Attributes of Street" dialog box
		Left-click on "Length" Title Cell to highlight whole column
		Right-click on "Length" Title Cell and Select "Statistics"
		Total Length is the number located after the string "Sum:"
	Result:  The total length of "Interstate" and "Interstate Ramp" street features is 11008.036280 meters.
