The METRO Green Line Extension Light Rail Transit (LRT) will run southwest from downtown Minneapolis through St. Louis Park, Hopkins, Minnetonka, and Eden Prairie communities.

The light rail transit line includes 16 new stations. It is part of an integrated system of transitways, including connections to the METRO Green Line, the Northstar Commuter Rail Line, bus lines, and proposed future transitways. The Metropolitan Council funded the estimated project cost of $1.858 billion through a mix of federal, state, and local sources. Construction began in 2018, with service beginning in 2024.

Sambatek provided stormwater services on the east segment of the METRO Green Line Extension, preparing 13 stormwater management reports, over 350 plan sheets, and drainage-related specifications for the 8.5-mile segment.

In addition to stormwater services, Sambatek provided multiple surveying and mapping services for the project. This included a project-wide 3D control survey, real-time and post-acquisition aerial control surveys, topographic surveys, comprehensive subsurface utility inventories for public and private facilities in compliance with ASCE SUE Guidelines for collection, and mapping of existing subsurface utilities. Sambatek also completed boundary surveys of existing railroad and highway rights-of-way and other properties along the east segment corridor. Field surveys and mapping were completed of complex BNSF Railway, Canadian Pacific Railway, and Hennepin County Regional Railroad Authority rights-of-way throughout the corridor.
