Dear Mr. Farkas:
On behalf of the Owners, please find enclosed the following items which have been

Please accept this letter as addressing page 1, section II, #lb. of the application pertaining to the

has made a check of the existing built upon area using aerial photography, past CAD drawings of
the property, property visits and Owner's verifications, to confirm that the approved built upon
areas were constructed within substantial intent of the approved plans and specifications which the
permit was based on.
Also, you have asked for the name and contact information of the person providing verification of
