The Takoma Park City Council this week adopted a $5.3 million budget for fiscal 1986 and approved an 8-cent reduction in the city's property tax rate.

But because of higher assessments, residents of Takoma Park, which straddles the Montgomery-Prince George's border, are expected to pay from 3 to 14 cents more in city taxes next year, officials said.

Based on the assessment increases, and on rebates Takoma Park will receive from the two counties for services the city provides, the 11,000 residents living in the Montgomery side will pay $1.48 per $100 of assessed value, up from the current rate of $1.45, officials said.

The 6,000 residents living in the Prince George's portion will pay $1.98, up from the current rate of $1.84, officials said.

The budget is about $800,000 higher than the spending plan for the fiscal year that ends Sunday, officials said. Most of the additional revenue will come from a $621,707 community development block grant from the state.

About $157,000 is for capital improvements. Most of that will be used for the continued redevelopment of Takoma Junction, located in the city's commercial center, officials said.

In other business, the City Council directed staff to select a replacement editor to oversee the publication of next month's city newsletter.

Mayor Sammie A. Abbott resigned as editor last month after the City Council passed a resolution barring elected officials from running the monthly paper.

Council members said they have received inquires from four residents willing to put out the July issue of the tabloid. The paper, which was to have been circulated to town residents Saturday, probably will not be published until mid-July, officials said.
