If Lawrence voters want to build a new police headquarters without raising taxes, they may have to live with less spending for parks and recreation and the delay of several major road projects, according to a new plan put together by City Hall leaders.

City commissioners at their Tuesday evening meeting got a glimpse of a first draft of how a $26 million police headquarters project could be built without raising either sales or property taxes.

“If we’re saying we don’t want to raise taxes, we’re going to have to re-prioritize,” said City Manager David Corliss, who drafted the plan but stopped short of recommending it Tuesday.

The plan centers on reducing for the next 20 years the amount of funding that would be available to the Parks and Recreation Department for capital improvements, major maintenance items and park expansion.

The plan also would delay several other non-parks and recreation projects. Those include:

• The rehabilitation of Fire Station No. 1 — the station located downtown — would be moved from 2015-16 to 2018-19

• The reconstruction of Kasold Drive from Sixth Street to Bob Billings Parkway would be moved from 2016-17 to 2017-18

• Construction of 19th Street from Harper to the new VenturePark would be moved from 2016 to 2017

• The reconstruction of Wakarusa Drive from Inverness/Legends to Sixth Street would be moved from 2016-17 to 2018

• City funding to rebuild Queens Road in West Lawrence would be moved from 2017 to 2019

• Reconstruction of portions of East 23rd Street would be moved from 2018-19 to 2019-20

• Reconstruction of Kasold from Clinton Parkway to the entrance of Hy-Vee would be moved from 2018 to 2020

• Plans to find space to combine the city’s building inspections department and the planning office into a central “one-stop shop” location would be delayed until at least 2021

One project that wouldn’t get delayed is the rebuild of portions of Ninth Street as part of a program to create an arts corridor in East Lawrence. Corliss said the project could use infrastructure sales tax money approved by voters in 2008, but that will require scrapping plans to rebuild Wakarusa Drive from Research Parkway to Clinton Parkway.

Commissioners took no action on the plan. A new City Commission will be seated on April 14, one week after Tuesday’s general election. A plan for a police headquarters — which was dealt a blow in November when voters rejected a sales tax for the project — is expected to be one of the first topics a new commission discusses.

But Commissioner Jeremy Farmer asked for the draft plan to be on Tuesday’s agenda to give the public an early look. He said he wants to give the plan serious consideration.

“They (police) have waited their turn,” Farmer said. “If moving forward means we have to repurpose some things, then that is what we should do as elected officials.”

In other business, commissioners:

• Approved about $100,000 in incentives to assist Tenants to Homeowners with its Cedarwood Senior Cottages project, an affordable housing project at 2525 Cedarwood Ave.

• Approved a waterline replacement project that will cause a portion of Ninth Street to be closed to traffic from May 26 to June 7. During that time, Ninth Street will be closed from just west of Hilltop Drive to just east of Avalon Road.
