BG, I admire the fact that you are doing everything you can in your area to at least try to “curb” the growth–much as the citizens of CV did with One Paseo.
With so little buildable land left, builders are definitely desperate these days, and are willing to exploit any scrap of dirt they can find–especially in San Diego.
Places like Playa Vista are great developments, and have a lot to offer. Yet, although friends who are long-time residents of Marina Del Rey, Manhattan Beach, etc., like having the amenities they offer nearby, they are not looking forward to the added congestion they will bring to the area–especially the beaches–which are already a zoo. I’ll take our beautiful and peaceful Del Mar and Torrey Pines beaches any day compared to that.
Like you, we don’t live near any of these concrete jungles, so, continue your valiant efforts, but also try to enjoy the fact that these developments bring added resources–just far enough away–so that we too can enjoy what they have to offer without sacrificing our way of life.
