5TH STREET COLLECTOR DESIGN GUIDELINES
5th Street North from CSAH 13 (Inwood Avenue) to CSAH 15 (Manning Avenue) will become the backbone of
future development along the I94 corridor, essentially becoming the primary access in and out of the future

The purpose of the proposed street standards are to 1) improve the function and appearance of the street, 2)
encourage pedestrian and bicycle use, and 3) reduce the potential for speeding. From a Community
