Neighborhood Response to MMM

In preparation for the hearings before the Weld County Planning Commission and the Weld County Board of County Commissioners in the summer of 2015, CLR-34 conducted extensive research and engaged consultants with expertise on key aspects of the proposed Martin Marietta Materials (MMM) aggregate processing facility.  The findings were compiled into a report submitted to Weld County.

Part 1 of the report is an introduction to the issues and an assessment of compatibility of the MMM project with surrounding land uses.
