Doug,
Then click on "On-Line Catalog" on the left side of the page. This will open a PDF screen on the page. Choose the "GT Series" towers, then "25G", and finally "Foundation Details". You can print these out if you need the "engineering diagrams" from Rohn for your project. Also - you might want to bookmark this link - it does not show up readily with a Google search... :-)
FWIW, I have a 60' Rohn 25G, set 4' in the ground and bracketed to my house at 28'. (By design, the overall height is 56' above ground.) I then have a 10' mast, with 6' above the crown of the tower, and a Diamond X500NA to the top of that, and - until recently - a Winegard super fringe TV antenna just
below that. I also have three other antennas side-mounted about 20' down the tower. This tower has survived 18 years now in northern Illinois, and recently only required that some of the mounting bolts be replaced due to tower movement wear on the bolts themselves - something that I'm told is a fairly common issue. Once the bolts were replaced, the tower was again strong and secure. A 30' tower will surely serve you very well, especially if you decide to bracket that to your house.
As some have suggested, make certain that you get your approval in writing before constructing your tower.
Good luck on your poroject.

My last posting for 2005 with a question:
My home owners association with their CC&R's and other regs [here in my
community of Vail, Arizona] has "seen the light" regarding new FCC
legislation on antenna and tower installation parameters and height
restrictions. They [the association] recently sent me a monthly
Newsletter [December issue] which specifically acknowledges word for
word, that the "Federal Communications Commission [FCC] passed
legislation that prohibits associations from restricting individual
members from receiving adequate transmission signals".
Yes, I did after reading this fired off an email to the manager of the
association [this morning] asking that they send me what is called an
Architectural Improvement form so I can submit my "project"...to install
a 30 foot Rohn tower for my 900 mhz antenna system and other antennas
related to repeater/remotebase and other link systems [a.k.a, antenna
farm on a tower].
My question on a typical tower installation and please keep in mind...I
have no experience in this area other then as a "helper" with other
installations years ago.
Can someone direct me to a website or specifically explain how best to
"lay the foundation" to install a 30 foot Rohn tower without guy wires.
Yes, I plan, once I purchase the tower sections [working on that with a
local Ham] to secure the second bottom section to the eave of the house.
In short, I think I want to sink/install the first five foot section of
the tower into the ground, use rebar for added support and firmness,
pour cement to "fill the hole" at the base of a five foot section of the
tower, then secure the upper section to the eave of the house with steel
brackets [that I may have to have formed and bent to the right config].
I am new at this so any and all suggestions on/from this list would be
appreciated so very much. This will be my new 900 mhz repeater and
remotebase project for 2006!! The wife and I have been living in our
new home now 15 months and I really desire to install a quality antenna
system for the three repeaters I currently operate and maintain.
So please comment/send thoughts and suggestions on your own experiences
with tower installatons. I am looking forward to "getting my hands
dirty", digging the hole for the tower and rebar and pouring the
cement...and at age 62, I NEED the exercise!!
Best 73 and **Happy Holidays**
