Thank you to all who participated in the planning process. The final document is made up of the main report and several appendices, which can be downloaded below:

Project Background & Overview

This corridor plan has assessed land use, transportation, market needs, and opportunities for improvements to the Main St. Corridor. The corridor extends from State Highway 66 on the north to Plateau Road on the south and encompasses one to three blocks on each side of Main St. The 5-mile corridor was divided up into four distinct character areas. This plan addresses the need to carry multiple transportation modes safely and efficiently on Main Street, while revitalizing the area, and creating opportunities for mixed-land use projects over time.  Throughout this planning effort, the project team worked closely with the community to identify proposed land use changes and growth opportunities, while honoring the unique and historic characteristics of the corridor.

Project Goals

Fortifying Main Street as the City’s Cultural, Business, and Commercial Center 

Main Street today has a mix of commercial, instructional, retail, professional offices, medium to high density residential, and service-oriented uses. This corridor is supported on either side by strong and established residential neighborhoods. Several high level goals have been developed for the corridor. These include: 

  • Embrace Historic Significance: Recognize the corridor’s place in history, automobile culture, significance as a gathering place, and as Longmont’s “historic main street” 
  • Strategic Infill: Revitalize the corridor through infill development, new housing, community facilities/amenities and urban open space
  • Strengthen Economic Base: Promote economic growth by attracting and retaining a diverse range of businesses and housing to strengthen the corridor, while preventing displacement of existing businesses and homes
  • Integrate Main: Create connections between Main St. and surrounding neighborhoods; connect streets and transition building heights and massing
  • Improve Safety and Mobility: Improve safety for all modes; preserve corridor mobility while enhancing the multimodal network. Incorporate technology to support safety and mobility.
  • Transit as Catalyst: Leverage transit investments – orient stops around activity centers and form new mobility hubs
  • Create a Sense of Place: Create a cohesive identity and sense of place; improve livability for all residents; enhance aesthetics and incorporate green spaces
