I follow Carol Leigh's CalPhoto eGroup discussion forum regularly.
Recently, one of the members posted information on a development project on private land right next to the Antelope Valley Poppy Reserve that would wipe out most of the prime fields in that area.
This acreage often has more spectacular blooms than the reserve itself. While it certainly is within the property owner's rights to develop the land, in this case it would require re-zoning for its contemplated use as a race track, "Fairmont Butte Motorsports Park." Here's a link their website: Fairmont Butte Motorsports Park. Info on the next public hearing, scheduled for June 9th, is posted there.
If you would like to oppose this development, please consider attending the hearing or voicing your concerns directly to the Los Angeles County Planning Commission. The specific case information regarding the Fairmont Butte project on the LACPC website is here. To contact them, go to their website Who Should I Contact? page. (Bad grammar is theirs, not mine...)
