HANNIBAL â With the Martin Street stormwater project essentially completed, the city of Hannibal is now focused on another major stormwater project on the South Side. On Tuesday night, the Hannibal City Council took a significant step forward regarding that repair when it approved an engineering agreement with Poepping, Stone, Bach and Associates. PSBA will be paid a lump sum not to exceed $98,255 for the design of the project which will include replacement structures for the 175 feet of stone archway that failed beneath Union Street a little over a year ago. Other services which will be provided by PSBA, which was recommended to the city council by members of the city staff and Hannibal Board of Public Works, include topographic and design surveys, geotechnical services, contract plans and cost estimates, easement deeds and construction services.
