When this was first proposed, I voiced my concern to the Council that it needed some real world examples to see how this definition would work in practice. At the Commission meeting of January 23, I pointed out that the majority of Pleasanton Ridge would not meet the definition of a ridge using the "as a continuous ground line connecting a series of hills located at their highest elevations ending at the last peak on each end of the landform at which the elevation of the ridgeline no longer rises in elevation, and only decreases in elevation". The reason is the majority of ridge is gently sloping to south without a "last peak" until it hits the valley floor miles away. I f the major ridge in town doesn't qualify under the proposed definition, the definition must be fatally flawed. At the conclusion of the Commission's discussion they directed Staff to rework the ridgeline definition and to also consider the idea of mapping the ridges. I have looked on the web to see how other regions have defined a ridge for hillside preservation and it seems that most agree with Commissioner Olson suggestion that a mapped inventory be used, rather than a verbal description. I strongly suggest the staff look at that approach. Thank you. Allen Roberts Click here to report this email as spam.
