The 2010 census for Jarrell was botched -- Badly.The population is way higher than what the 2010 census says it was, and it's also had explosive growth ever since.The city of Jarrell is also only a very small part of the story.

I grew up in Olde Town Arvada, served in the Army in Explosive Ordnance Disposal.  

If the ground will not perk, you might be able to excavate (for instance) 6 feet down and find pure sand or some other better soil.In Southern Nevada I've seen Caliche (if that's your problem) run in bands 6 to 8 feet deep and below that sand (but maybe your bands are 100 foot deep, who knows).Caliche can tear up mechanized equipment pretty bad, but I've seen people go through it with pick and shovel (and explosives) to install pools (but I've not seen it done for a septic field).Just my 2 cents.

The growth here is explosive.

The swing isn't quite as wide up in the East Bay - but partially because summer isn't quite as explosive either.. 

(Gulf of Tonkin, Iraqi WMD, Panama, Granada, explosion on battleship Maine....)

To give history as to why we had an airbnb explosion (as many cities did) and at the height there were 2250 short term rentals in KCMO and only 7-8% of those were licensed and legal.

There has been an explosion of real estate Gurus.

The area does well now and the potential is explosive, so much growth happening in Casa Grande, Coolidge, and Eloy.I have helped investors purchase in all of the above markets and manage the same properties.

xid=527#This will turn up interesting info for the patient person.A search like this for my old street would turn up a meth lab explosion, for example.
