Eustis Street Improvement Design

Project Summary

Eustis Street is located within Ramsey County in the city of Lauderdale, MN, adjacent to Highway 280. The existing road suffers from pavement deterioration, sidewalk inaccessibility, and flooding due to inadequate drainage systems. The project corridor contains eight commercial and residential properties. We considered various alternatives to remediate the current challenges of the site. Existing stormwater was evaluated to propose an improved stormwater collection system. In addition, new pavement design was evaluated for a 20-year design life that considers the site’s projected traffic loading. Finally, a continuous sidewalk design was selected based on a cost analysis of alternatives to provide access across the project limits.

Design Goal

Ramsey County is reconstructing a 0.27-mile stretch of Eustis Street from the southern city limits of Lauderdale to Larpenteur Avenue West to provide adequate drainage capacity, construct a continuous and accessible sidewalk, and correct existing pavement deterioration. The improvements will minimize the impact on surrounding residences while improving the overall quality of life for those using and living in this corridor.
