Larkspur is asking more residents to weigh in on the future of the 113-year-old City Hall.

A historic structure report on the property was completed in June and details various renovations that are needed. It also lays out three potential renovation design options that vary in cost and scope.

“The building has known seismic and fire sprinkler deficiencies and multiple building components in need of costly repair,” Julian Skinner, the public works director, wrote in a Nov. 25 memorandum to the council.

Since the release of the report in June, the city has sought comments on the project from the community in various forums, including a City Hall tour, a public meeting, a community workshop and an online survey.

The City Council is expected to receive an update on the public engagement efforts at its meeting at 6:30 p.m. Wednesday, Dec. 3. The city will take additional public comments during the meeting and is set to discuss next steps for the project.

The three renovation options include a $6.3 million short-term update that will address immediate needs and provide around 10 years of additional building use; a $21.8 million significant remodel that is expected to last around 30 years; and a $23.7 million upgrade that would last about 50 to 100 years, equivalent to a new building.

Skinner said there might be an option to incorporate aspects of each design option into the final renovation plan.

All design options are intended to address structural and infrastructural needs while maintaining the building’s historic features. In order to maintain the historic designation, which contributes to the downtown’s historic designation, the city says any renovation must maintain the front facade and overall “mass, shape and roof line.”

The city’s online survey on the project will be available until the end of the year. The questionnaire, available on the city’s website, asks residents about issues such as design preference, possible solar panels and a potential property tax to support the project.

“To date, the City has received 41 responses to the online survey,” Skinner wrote in his report to the council. “Generally, responses have been similar to the in-person feedback provided at the public workshops. Several respondents have requested more in-person meetings on different days and at different times of day to broaden awareness of the project. A theme of responses to any sort of tax measure is that there is not enough information at this time — the question needs to be asked when the future uses of the building are more defined and the cost per property is known.”

Skinner said Larkspur will continue additional public engagement efforts in the new year. Once a design option is chosen, the city will discuss funding options. Renovations are expected to begin in the next several years.

Joan Lubamersky, a former member of the City Council, sent officials an email Tuesday calling for more communication.

“I urge that funds be provided for significant public education and outreach,” she wrote. “It is clear from the very limited number of people who responded to the survey and who attended the city meetings that additional efforts must be made to share information and ask for input on this vital project.”
