Jason,
Larry Davis has informed me that you are not quite ready for the pavement work. The water line has not been
pressure tested and treated, we have no density reports on the utilities. If you did not have a lab to take
densities on the backfill of the utilities I would advise you to remove the backfill and replace with the proper
testing prior to beginning any subgrade prep and pavement work. These utilities will be ours to maintain for
years to come and we will not accept them if they are not installed properly.
As far as the subgrade, according to the geotech report, lime stabilization is recommended, if not, at the
minimum we will require cement stabilized subgrade and increase the pavement by 2 inches. Please have your
geotech submit us a revised recommendation on the subgrade preparations for us to consider. The roll up curb
is acceptable as long as we have 30' back to back of pavement section. We will allow you to pour this section
as you did on Lost Creek, however it is at your risk and if it does not come out to our satisfaction we will ask
you to replace it.
We are also waiting on the mix designs for your concrete for pavement, inlets poured, manholes and stamped
concrete. Please submit those as soon as you can.
It appears that you have been placing debris and materials on the neighboring property, you will need to clean
up that site before we get complaints from the owner and from code enforcement.
If you have any questions please contact me at your convenience.
thanks,
Mike

We are finally complete with our underground wet utility work and ready to get going on the road. I have
spoken with Mark Gray, P.E. of Rone Engineering and he said that due to the low plasticity index of the soils
on our site lime stabilization would be of no benefit. We would like to propose increasing the thickness of
the pavement by an inch instead which would be of greater benefit to the long term success of our roadway.
Also we would like to ask to be allowed to hand pour these roads like we did at Lost Creek due to the
minimal area that would be able to be slip-formed. Theses are dead end roads of short lengths and we can
achieve a high quality hand pour in this situation.
Also we are intending to do the roll-up curb as previously approved.
Respectfully,
