While an employee of Meckel Engineering & Surveying, Eric Olson of HMH Engineering provided the drainage system design for the Galena Ridge Golf Community at Silver Mountain Resort in Kellogg, Idaho.  Master-planned as an 880-unit community and situated on hillsides amongst former mining operations and Superfund remedies, the project proposed many unique challenges.  Due to fine-grained soils, infiltration of runoff was not an option.  The drainage system developed was a combination of storm sewers, rock-lined ditches, grass-lined biofiltration swales, and detention ponds with various types of outlet structures.  The project also altered a number of “improved” drainage courses that had been installed by the Army Corps of Engineers as part of the mining cleanup effort.  Project permitting included the City of Kellogg, Army Corps of Engineers, IDEQ, EPA, and the Panhandle Health District’s Institutional Controls Program.
