CORRECTION: This story originally misreported the date set for final approval of the city's new Civic Area Master Plan. That is scheduled for Sept. 3.

Achieving the vision of the Civic Area Master Plan will require working closely with community partners, including private property owners, arts organizations and the farmers market, Boulder City Council members said Tuesday night.

They endorsed the general approach of the draft Civic Area Master Plan, even as they urged caution in the implementation.

The plan envisions a revitalized park and natural open space along the creek with east and west "bookends." The east bookend would include a year-round market hall and expanded farmers market, as well as new office buildings that combine city services and incubator space for entrepreneurs. The west bookend would include an expanded library with a cafe and new performing arts center. The current municipal building and the civic use pad at the St. Julien Hotel could also be dedicated to the arts.

City officials said they plan to start developing some of the park aspects of the civic area plan almost immediately, including adding lighting and programming and changing landscaping to improve safety.

The park area will also include numerous play areas for children that tie into the arts, nature and science.

"The civic area is going to be a great urban park, and it is going to be the stage on which we perform all these great civic functions," said Jeff Dillon, Boulder parks and planning superintendent.

Project coordinator Sam Assefa compared the proposed development on the east end of the civic area to San Francisco's Ferry Building, which includes a farmers market, related shops, government offices, nonprofit organizations and for-profit businesses.

That kind of mix would keep the area vital and active through the day and evening.

"That doesn't mean we could replicate that, but we can look for what the Boulder version of that would be and create that on the east side," he said.

Christian Toohey, a board member of the Boulder County Farmers' Market, said many farmers are concerned the market hall could end up detracting from their brand. The Boulder County market, unlike many others, does not allow vendors to buy from other people and resell. That keeps the market distinctly local and focused on producers.

A market hall with more craft products could change the feel of the market.

Councilwoman K.C. Becker said there should be a feasibility study of the market hall before any significant investment is made.

Assefa said the plan is designed to be flexible, and various proposed uses can move around within the plan or change in response to new information.

However, the plan is designed to create a vision for the future.

Councilman George Karakehian urged city planners to include groups like the Dairy Center for the Arts and downtown organizations to make sure the civic area plans don't detract from other parts of the city.

"I hope that whatever happens across Canyon (Boulevard), it should add to what's going on downtown and not take away from it," he said. "It's not enough reason to not go ahead, but it is a concern of mine."

Boulder Mayor Matt Appelbaum said the city shouldn't be afraid to change the central area and the buildings in it.

"There's nothing wrong with saying these buildings have served us for decades and decades but our downtown has changed and our needs have changed," he said. "If you do that every 70 years, that's not so bad."

Becker said that as future city councils consider approving specific uses, they need to thing of the long-term impact.

"I would encourage council to think about what is right for the space for the next 100 years," she said.

The Civic Area Master Plan is scheduled for final approval Sept. 3.
