Sustainable Remediation Project: Crane Lake Visitor Center

Challenge

Solution

Crane Lake Township collaborated with SEH and the National Park Service to redevelop the former resort into a visitor center. SEH provided preliminary and final design while also aiding the Township in obtaining grant funding from the Legislative-Citizen Commission on Minnesota Resources (LCCMR) for the visitor center and RV park construction project. To cover the environmental cleanup expenses for the project, SEH also prepared a Minnesota Department of Employment and Economic Cleanup Grant, which secured an additional $87,240 for the project.  

As part of the design services, SEH conducted feasibility studies for the visitor center and associated campground, developed conceptual designs, handled property survey research, prepared a topographic survey, conducted wetlands surveys, coordinated Section 106 review and geotechnical assessments, and prepared bid specifications for the project.  

To address the petroleum impacts on the site, SEH conducted a Phase I and Phase II Environmental Site Assessment (ESA) in conjunction with the geotechnical assessment to evaluate soil, groundwater, and soil vapor conditions. SEH also prepared a Response Action Plan (RAP) and designed a vapor mitigation system for the new building.  

In addition, SEH enrolled the project into the Minnesota Pollution Control Agency (MPCA) Petroleum Brownfields Program, which supports the cleanup and remediation of contaminated land, and successfully obtained RAP approval. During construction, SEH will implement the RAP, including installation and verification testing of a sub-slab depressurization system to prevent vapor intrusion.  

The SEH team closely coordinated with the MPCA and their contractor in remediating the contaminant plume to prevent it from impacting Crane Lake. The design plan required careful thought regarding the project’s environmental needs and constraints, such as incorporating trees and wetland areas and maintaining a safe distance from the lake. These efforts will create a sustainable community asset for years to come, with an opportunity for additional expansion in the future.  

The Visitor Center is expected to be complete in 2024.
