The Downtown Drainage Project is underway in the area of Fourth Street and Osage Avenue. The project actually began last year with drainage system improvements at the Tower Center at Unity Square site, which was completed first so that construction could begin on the community green space. Work recently resumed to include the remaining project area, between Adams Boulevard and the 300 block of Osage Avenue. According to City Construction Inspector Dan Basler, closed lanes on Osage in the Fourth Street area should be open early next month, at which time lane closures will begin on Fourth Street west of Osage.The drainage system replacement project is funded through the voter approved 2013 half-cent Capital Improvement Projects (CIP) sales tax. Voters have extended the CIP tax for capital projects every five to seven years since 1999.
