MEMORANDUM
Meeting Date: July 25, 2023
Subject Title: City Council Agenda Item No. F.1.
Appeal of the Planning Commission's decision to approve Costco Prepared By: Jennifer Hagen, Senior Planner
Submitted By: Alexis Morris, Community Development Director Erik Nolthenius, Planning Manager
It has come to staff’s attention that the Figures within the Costco Environmental Analysis included as Attachment 16 of Agenda Item F.1. were coming up blank in the published agenda packet. In order to provide a clear and complete record, staff has included the four figures here for the record. In addition, the Environmental Analysis linked in the report to our City’s website has been updated and is complete and correct.
