I think there is great value in having NIMBY’s and Non-NIMBY’s involved in these decisions–as was proven with One Paseo. These developers were actually lucky to reach a compromise, since the developer of the Agua Hedionda Lagoon project in Carlsbad just conceded defeat by a small margin.
If everyone wanted to live their lives in the same way, there would be no conflict. Fortunately, we don’t, so I think the checks and balances these opposing POV’s offer help keep things in balance.
Soon, there will be no more buildable land–especially in coastal SoCal–so these discussions will be moot.
