Environmental Resource Committee

The Environmental Resource Committee (ERC) is an OLCA committee made up of active, passionate individuals from different parts of the landscape industry working to keep our membership up to speed on “sustainable landscaping”. Over the last decade, the mission of the committee has been to help connect OLCA members to current affairs, useful resources, continuing education, new policies, and programs available to members.   We also help represent the interests of OLCA’s members in conversations with regulatory and educational agencies. 
We meet up to 6 times a year in the Portland area. Those from further away can participate by helping out on projects & sharing information. If you want to join in or have any information to share, please contact us at
info@oregonlandscape.org.
 

History

In 2002, OLCA directors Drake Snodgrass of Drakes 7 Dees and Matt Triplett of Willamette Landscape Services promoted the need for our association and its members to be better prepared to deal with emerging environmental issues.

From 2003 to 2007 the ERC focused much of its work on issues around water conservation.  Under the leadership of Scott Winkelman of Drakes 7 Dees and Kelly Duncan of United Pipe, we developed a training and certification program named Water Wise. Partnering with water purveyors like the Eugene Water and Electric Board, we promoted landscape contractors who reduced water waste through Best Management Practices of soil preparation and of irrigation design/installation.

From 2008 through 2010 Doug Spiro of Spiro Landscapes led the ERC in addressing even more “sustainable landscaping” issues in reaching out to various local and state programs. We have contributed both industry expertise and perspective on both practices and policy to Ecobiz, Oregon Tilth, Earth Advantage, and Metro.

Since 2011, Corey Petersen of Pacific Landscape Management has led the expansion of educational opportunities. Working with the Expo Committee, we have promoted many classes for members to receive continuing education credit and to better understand sustainability in our industry.
