Congrats Shooby!
I purchased a neighborhood 10 residence 3, also on the greenbelt. Looks like we will be neighbors. I am a bit irked that they didn't let me reduce my purchase price like they did for you. However, i'm still very happy with my purchase. I'm using my incentives to buy down my rate and pre-pay 2 years of HOA. I'm going with the cheap carpet and tiles but am adding extra padding under the carpet.
I agree that UAMC is slow as heck right now and impossible to get a hold of, but I've been reassured that the loan approval deadline would be met. when you do get a hold of them, they are very polite and helpful. Supposedly Lennar signed 30 purchase agreements during the week of the sale so UAMC is swamped with loan applications.
Regarding the ground water comment, I did my homework when it came to Camden place. Being a technical guy and extremely attentive to detail, I researched the SNA flight paths, FEMA flood map, earthquake liquification map, and even read all related Navy reports regarding the cleanup of waste/ground water and such (VERY BORING!). All plumes and areas of concern have been cleaned and have been deemed "NFA" - "No further action required". In fact, most of the plumes and areas of concern are not within the boundaries of Camden Place. UST 268 was the only area that concerned me. I don't plan on growing fruits/vegetables on my land nor do I plan on drinking from a well dug deeper than 6ft underground, so I've come to the personal decision that i'm okay with the level of risk involved.
Here are some important links I found during my research. They may be of interest to any Camden residents or prospective residents.

Definitions of acronyms I didn't understand:
VOC - Volatile organic compounds, petroleum substances used as the vehicles for many printing inks.
PAH - polynuclear aromatic hydrocarbon. PAHs are the most common smaller and more volatile compounds found in oil.
PCB - Polychlorinated biphenyl, a synthetic, organic chemical once widely used in electrical equipment, specialized hydraulic systems, heat transfer systems, and other industrial products. Highly toxic and a potent carcinogen. Any hazardous wastes that contain more than 50 parts per million of PCBs are subject to regulation under the Toxic Substances Control Act.
TCE - Trichloroethene or trichloroethylene. A contaminant that is a component of cleaning solvents. TCE is a commonly found contaminant at Air Force bases resulting from the cleaning of aircraft and equipment.
NFA - No Further Action
