Who else “signed off” on the eruv?
After all legal contracts with all the utilities, agencies, organization and all are completed, the “reshut” (permission) to lease the land located within the Eruv for a pretty long time (we used 99 years) must be secured. We created a certificate-sized document attesting to the fact that for the transfer of 1 silver dollar between the Palo Alto Community Eruv and each of the entities with whom we needed to create the lease, that the area within the Eruv would belong to the PACE for only the purpose of carrying on Shabbat and Yom Tov that falls on Shabbat and Yom Kippur. This document and the silver dollar attached to its face (all within a nice frame) was handed to the representative of the relevant organization (e.g., governor, mayor) and a “kinyan” was made. That is, the certificate was placed in the hand of the individual and they raised it up from our hand signifying that they were taking ownership of the certificate and were agreeing to the terms written within the certificate.
