Subject: Questions for AJ & Amy
AJ/Amy,
I have no issues with the City. I'm trying to make sure that when I go to make changes to my home that
everything is done accordingly and correctly. If there are any problem areas, I want to fix them now once and
for all. The questions I'm asking are to help me figure out what things need to be brought up to code. I want to
make sure everything meets code when I'm done.
Thank you in advance to answering my below questions. The background information for my questions plus
my 11 questions are below. This email is a California Public Records Act (CPRA) request.

Bryan McKinney, City Engineer wrote "For housing developments, the developer is required to have their
surveyor verify pad elevations prior to issuance of building permits. Amy or AJ should have a copy of this."
AJ/Amy - Figure 1 shows lots 1 and 2 on the left and lots 29 and 30 on the right. All four lots are Plan 1 floor
plans like mine. In 2007 1 made an offer to buy the Plan 2 home on lot 3 that boarders the abandoned Plan 1
foundation on lot 2. None of these foundations had been poured when we made our offer. It was at the top of
the real estate market before the crash. The foundations on lots 1, 2, 3 and 4 were all poured at the same time.
Shortly thereafter the foundations on lots 27, 28, 29 and 30 were poured. We subsequently made an offer to
buy the Plan 2 home on lot 28. 1 looked on the as -designed precise grading plan for lot 2 with the abandoned
Plan 1 foundation. It appears that there isn't a 1 foot freeboard between the curb and the pad.
1. Did the City issue building permits for lots 2, 29 and/or 30?
2. If no the permits were never issued, was it because the surveyor determined that there wasn't the
required room for the minimum of 1 foot of freeboard?
3. If the permits were issued, why weren't these homes on lots 2, 29 and 30 ever built?
4. If no the permits were never issued, can I get a copy to that correspondence?

Bryan McKinney, City engineer wrote "I am not saying your pad elevation was determined by the top of curb,
just that we have to determine it that way when there is no 100-year water surface."
Engineering Bulletin #06-16 (see page 17 illustration that shows the 10-year and 100-yearwater surface/flood
elevation) - https://www.laguintaca.gov/home/showdocument?id=27107
AJ/Amy — Figure 2 is a cross section of my street from the rough grading plan. Based on page 17 in the City's
Engineering Bulletin #06-16, the R/W lines in Figure 2 at the curb's edge show the water surface elevation for
a 10-year storm for a 24 hour event.
5. Did they forget to include a R/W line as shown in the Bulletin for a 100-year storm for a 24 hour event?
6. If yes, then how would the surveyor shooting the pad elevations know if there was room for the
freeboard requirement for any of the homes on my street?
7. Do you know where the 100-year storm for a 24 hour event R/W line is on lot 13, which is my lot?
8. Does the City have any information that shows there is a minimum of 1 foot of freeboard between the
100-year storm for a 24 hour event R/W line and the pad for my home on lot 13?

Bryan McKinney, City Engineer wrote "The pad elevation is the final graded earth elevation on which your slab
rests."
"Post -tension concrete slabs are used to create a monolithic (single pour) slab that is stronger than a
traditional slab without reinforcement. This is achieved by laying out high -strength steel cables in a
crisscrossed grid pattern throughout the foundation prior to pouring the concrete."
Link to a pre -monolithic pour picture (the link will open) - https://aftconstruction.com/what-is-a-post-tension-
concrete-slab/ You will see on the picture on the link that the final grade includes the footers on the perimeter
of the slab since they are all load bearing walls.
Taken from a letter dated February 06, 2007 that I received from the City. Bob Roper, VP of Operations for my
builder wrote to Kirk Kirkland, the City's Senior Building Inspector regarding Tract 32279 Model Slabs ( Lots
13, 14 15) and stated "The slabs were poured under the supervision of a deputy inspector using a monolithic
technique. The Construction Manager, Chris Hayes, was covering two model home complexes at the time, and
has placed slabs in many neighborhoods that were post tension, monolithic pours, which is why one inspection
was called instead of two."
The City has two pour inspections when a traditional footer-slab design is used. The first is for the pouring of
the footers and the second is for the pouring of the slab.
The City has a minimum difference in elevation between the finished floor and the pad of 6". There is no limit
as to the delta between elevations as long as the 6" minimum is met.
AJ/Amy - Figure 3 shows my wife standing at the entrance of the Plan 2 home being built on lot 3. If you dig
around the entire perimeter of that post tension slab, you will find the pad is 24" or more below the finished
floor. This is also true with my home on lot 13.
9. For calculating freeboard for my home on lot 13, would I use the pad elevation below the finished floor
elevation (a delta of 24") to calculate freeboard from the 100-year storm for a 24 event?
10. If yes, has the freeboard calculation ever been done for my home using the pad elevation 24" below the
finished floor elevation?
11. If you wouldn't use the actual pad elevation that is 24" below the finished floor elevation, can you
provide the code that supports that?
