VIRGINIA BEACH, Va. — Virginia Beach city council members will vote on a resolution for an independent investigation into the mass shooting at the Municipal Center Tuesday night.

City staffers are also recommending one plan for the future of Building 2 that would renovate the building for police department use.

Council members recently discussed three options that would either provide fully renovated or entirely new facilities to house the workers displaced from Building 2.

City Manager Dave Hansen and other city staffers recommended that city council move forward with option three -- a plan to renovate and redesign Building 2.

Option 3 would cost $133 million, with $4 million needed in the fiscal year 2020 in order to give the city more power and flexibility with construction and redevelopment.

The $133 million includes an estimated $50 million for the already-planned construction of a new city hall building. If approved, 'Option 3' would move the four departments displaced by the shooting - Public Works, Public Utilities, Planning and IT - into renovated versions of Building 1 and Building 11. 

The plan estimates this project would be completed by fall 2023.

Mayor Bobby Dyer wrote a letter to Governor Ralph Northam asking for financial support from the state general assembly during the upcoming session. Dyer asked for $10 million in cash and a $20 million loan in the letter, City Manager Dave Hansen said.

Two other points of discussion for city council on Tuesday will be potential changes to their policy on guns in the workplace as well as a resolution to hire a third party to conduct an independent investigation into the mass shooting.

Council members and family members of the victims have made calls for an independent investigation.

The resolution would direct the city auditor to work with an independent consultant, who would look at the events surrounding the shooting and review personnel files.

The consultant would then give council members a report on the shooting, city policy, security upgrades and the shooter's background, among other things.

During the discussion about guns in the workplace, councilwoman Jessica Abbott recommended an anonymous survey where all city employees could share their thoughts on security, guns and safety improvements. No decision was made.
