ITEM NO. 5.1. City of Elk River MEMORANDUM TO: Planning Commission FROM: Stephen Rohlf, Building and Environmental Administrator Date: September 23, 2003 A SUBJECT: Conditional Use Permit for Mineral Excavation by Aggregate Industries/ P.H. CU 03-29 Request: Aggregate Industries is requesting to expand an existing fifty (50) acre gravel mine • to include an additional eighty (80) acres. Mining the property in question has been anticipated for a long time and was included in the City of Elk River's 1994 Environmental Impact Statement (EIS) on Mineral Excavation and is already zoned Mineral Excavation Overlay Zoning District.

The eighty (80) acres in question do not contain any wetlands and, except for adjacent to houses on the site, there aren't any trees on the property.
