• STAFF ORIGINATOR: CITY COUNCIL MEETING DATE: TOPIC: AGENDA ITEM 6C(ii) Michael Grochala November 23, 2009 Consideration of Resolution No. 09 -103 Authorizing Report on Improvements, 21st Avenue Realignment ACTION REQUIRED: 4/5 BACKGROUND In October the City entered into a Joint Powers Agreement with Anoka County for the reconstruction of the I -35E /CSAH 14 (Main Street) Interchange. The interchange project includes modification of the existing local street access with 21st Avenue.
