Frisco City Council voted Tuesday to approve the update to the Downtown Master Plan, making way for major changes to come to the city's historic area.

The updated plan includes a Fourth Street Plaza in the heart of downtown, a design district that would attract new businesses and a new design for Main Street.

In a previous story, Frisco Development Services Director John Lettelleir said it could take several years before construction began on any of these projects. And any projects that do not follow the current zoning would have to go through the zoning process, Lettelleir said during the meeting.

For Main Street the plan recommends that the existing median be replaced with a center turn lane, which would allow for the outside lanes to be narrowed and provide for wider sidewalks. On-street parallel parking would remain, but there would be an option to remove it if the council decides in the future it is no longer needed.

The average daily traffic through downtown is about 20,000 vehicles, according to the city. Council Member Will Sowell noted that though Main Street through downtown is not intended to be a major thoroughfare, drivers would still use it often.

The Fourth Street Plaza would be in the heart of downtown and would run along Fourth Street from Oak to Elm streets. A portion of Fourth could be closed to traffic so the plaza can be pedestrian-focused. The plaza is intended to bring in new restaurants and urban living.

The plan also includes a mixed-use design district between the Frisco Heritage Center and the Silos. This district would link downtown and Frisco Square through shops, restaurants, studios and showrooms anchored by a pedestrian-focused promenade.
