The boat and trailer parking areas between Third Street and the Fifth Street ramp will be upgraded with new paving and drainage facilities.
This work begins on Monday, Sept. 20, and will continue through the end of next week.
Parking will be available to the north at the site of the future Lakefront Park, formerly known as the Natural High property.
The Fifth Street boat ramp will remain open, but ramp access will be subject to delays due to the construction work.
On Sunday, Sept. 26, beginning at 8 p.m., and continuing until 6 a.m. Monday, Sept. 27. North Main Street between First and Fifth streets will be closed with a detour provided.
Fourth and Fifth streets will be closed from North Main Street to the parking areas near the lake. The Fifth Street boat ramp and all lakefront parking lots will also be closed.
The department said it will issue its next construction update before additional work scheduled for Sept. 28 through Oct. 1 begins.
