As one of the 5,000-plus residents who signed petitions to vote on the City Council's approval of Oak Grove, and as one of the vast majority of Pleasanton voters who subsequently passed Measure PP, I object to the charge of NIMBYism from Oak Grove supporters (see "Open space park would be an asset," Letters, March 12, page 8). Some residents of Kottinger Hills do indeed actively oppose Oak Grove. But quite obviously, most of us who object to this development in the Southeast Hills live elsewhere. Let me describe two much more universal reasons for opposing it. The plans for Oak Grove will involve significant environmental damage to a pristine area; and the end result will be a mere 51 houses, but of colossal size –- up to 12,500 sq. ft. For many, perhaps most, the promise of open space parkland is not enough to overcome these fundamental objections to Oak Grove.
