Subject: Griffith  Park acreage?
Dear Joe:
I recently reviewed the RAP Mitigated Circulation Plan dated 1/16/2015.   On page 9 it stated Griffith Park is 4355 acres.  I would like clarity of the acreage of the park based on the following data:
*Attached Map from 1923 shows Griffith Park as 3751 acres
*I have RAP commission documents showing the Hollywoodland Gifted Park Donation  in 12/1944 as a donation of 444 acres (see second attached map).  This totals 4195 acres.
Please explain how and when the other 160 acres of land was acquired, purchased or donated to total 4355 acres as currently stated in your 2016 document.
I look forward to your response.
Thank you
