Ehrhart Griffin & Associates (EGA) was retained to perform all land surveying and civil engineering tasks for a brand new 500,000 square foot, 50-acre mixed-use commercial development located in Omaha, Nebraska. This project, located at the northeast corner of “L” Street and 120th Street, was designed and constructed on a portion of the former undeveloped Avaya (Connectivity) site. Total construction cost of onsite improvements, including buildings, was approximately 32 million dollars.
Based upon a developer approved master plan, onsite design tasks that the EGA team performed topographic survey, preliminary and final plats, geometric layouts, site grading, utilities, roadway and parking lot design, drainage, and storm detention calculations. Intense coordination between contractor, developer and tenants was required to meet the specific needs and specifications of each leased space.
Offsite design tasks included a traffic study, traffic signal design, and the design of approximately 8.6 million dollars in public improvements for the widening of “I” Street, 120th Street, “L” Street, and the entrance ramp onto Interstate 80.
The Marketplace is fully developed, anchored by a Super Target store, and contains a “town square” approach that houses smaller tenants in the center of the project and numerous outlots along the perimeter of the site. Other major tenants include, among others, Best Buy, Sports Authority, Office Max, and Petco. This project was one of the first major developments constructed under the Omaha by Design guidelines.
The City of Omaha was the governing agency for all permit review. EGA performed construction observation for site infrastructure.
All survey and design information used to create the platting and construction documents were prepared using state of the art electronic surveying and computer aided drafting (CAD) equipment and software.
