Re: 1831 Newport Hills Drive East
Dear Samir,
Our client has paid for an expedited review. Would it be possible for you to review
this modification request on a fast track basis?
Currently, our project is in the second plan check review, and Kenneth Huang is the
plan checker. Kenneth met with Dan Kennedy to discuss this detail, and they felt
that this would bean acceptable solution without having to redesign the project.
Thank you for your consideration. I appreciate your time.
Sincerely,
Ron Thorpe YY
Project Manager

Re: 1831 Newport Hills Drive East
On behalf of C. J. Light Associates, we are requesting a modification to the CRC Code
to allow us to provide a two-hour fire rated assembly detail at the entry level
deck/lid to the gym at the basement level below. This detail will also include a fire
sprinkler head at the lid of the two-hour fire rated assembly.
Per current CRC Code Section R 310 under Means Of Egress, escape openings must
exit out directly into a yard. By definition of yard, it must be open from ground to
sky. By providing the two-hour fire rated assembly and fire sprinkler, it will allow
for additional protection and time for egress and rescue to take place, should it ever
be needed.
