Rain Gardens -- An Economic and Environmentally Friendly Stormwater Treatment Solution


​Frequently, the developer or homeowner is faced with a situation where it is not possible to utilize existing stormwater treatment infrastructure for a new construction or reconstruction project.   A Rain Garden can be an ideal solution that provides effective stormwater treatment and is often very cost effective to construct.  Resembling standard landscaping, the rain garden collects stormwater from roof drains and other impervious surfaces and detains it for treatment through natural infiltration.   Stormwater entering the rain garden flows through vegetation, and associated root systems, allowing the water to be filtered prior to entering surrounding native soil.   The rain garden is an accepted stormwater treatment facility by most regulatory and permitting agencies.  

Construction of a rain garden is fairly straight forward and inexpensive process, with the primary requirements that the garden be sized appropriately for regulatory rain storm events and that existing soil provides a minimum level of infiltration.  A simple soil infiltration test can be performed at the site of the planned rain garden and then the garden sized by an engineer to accommodate required stormwater flows. 

Contact LEI if you would like more information about using a rain garden to address your stormwater treatment need.

Lookout Pass Ski Resort Expansion EIS Completed

​The Lookout Pass Ski Resort Expansion EIS has been approved for implementation: https://data.ecosystem-management.org/nepaweb/nepa_project_exp.php?project=43757   LEI completed the road engineering, logging system engineering, and timber economics components of this project, as a sub-contractor to SWCA Environmental Consultants (www.swca.com).  

This project took nearly three years to complete and drew on LEI's extensive NEPA and timber sale NEPA experience to complete.

As stated in the final NEPA document: 

"The purpose of Lookout Pass Ski and Recreation Area's proposed expansion is to provide a high-quality downhill skiing recreation opportunity on the Idaho Panhandle National Forest and Lolo National Forest. Currently, ski area terrain is insufficient to consistently meet demand by the local skier market, resulting in diminished recreation experiences during high-visitation days. Expansion of the Lookout Pass Ski and Recreation Area would provide more skiable terrain and more efficient lift systems to enable the ski area to ensure a high-quality recreation experience for a wider range and number of skiers."

LEI principal engineer Greg Zartman, PE, was the lead engineer for this project and completed all of the road engineering, logging systems, design, and timber economics tasks for the SWCA team.

LEI teams up with AMEC for the Katlian Bay Road Project for State of Alaska

LEI-AMEC LogoAs arguably the top engineering firm in the country when it comes to low volume road engineer, LEI is excited to announce that the Alaska Department of Transportation and Public Facilities has awarded LEI and AMEC the Katlian Bay Road project. LEI is teaming up with the worldwide engineering giant, AMEC Foster Wheeler, to provide professional engineering services that will provide access to public lands and the US Forest Service (USFS) trail system beyond the private lands in Katlian Bay. The USFS has designated the existing Katlian River Trail beyond the private lands as open to all non-highway legal vehicles 60 inches wide or less. This trail provides recreational and subsistence opportunities for the public including fishing, hunting, hiking, berry picking and ATV use.
 
There is also potential that the private lands in Katlain Bay could provide a material source for future development in Sitka. The community has expressed a need for a rock source in the Sitka area to support future development and construction projects.
 
LEI has been doing work yearly in remote locations in Alaska since the early 1980s. In addition, LEI has completed more than 23 NEPA related projects in Alaska, most of them with multi-million dollar budgets and hefty six figure logistics budgets.
 
Meanwhile, as one of the world's leading engineering project management and consultancy companies, AMEC will provide its expertise in environmental public involvement for the Katlian Bay Road Project.
