Section 4.2.27 of the Orange County Zoning Ordinance as, "The land area within
one-half mile of the normal pool of an existing or proposed water supply
impoundment, or the ridgeline of the watershed, whichever is less."
C. The roads noted are major transportation routes where a 3-mile buffer is created
on either side of the centerline. The road miles for the 12 distance do not use
back roads in this version.
D.l. Wetlands - As defined in the Open Space Standards of the Orange County
