Perry Street Storm Sewers
Impacted Wards - 2
Several homes are subject to frequent flooding due to an undersized and substandard storm sewer along Perry Street and 2nd Street, located within the Saint Charles Historic District. The purpose of the project is to replace undersized storm sewers along Perry Street from 3rd Street to 2nd Street, along 2nd Street between Perry and McDonough, and along Water Street from 2nd Street to the outfall(s) at Blanchette Creek. The existing storm sewer pipes range in size from 12 inches to 48 inches, with parallel storm sewers in some areas.
The City's records and mapping do not clearly define the locations of the existing storm sewer pipes and outfalls; therefor, the project will require investigation of the existing storm sewer network in the area by means of survey, dye testing, camera inspection, etc. The design consultant will also evaluate the watershed to determine storm sewer capacity requirements and will be responsible for determining pipe sizes, inlet spacing, routing and final design of the stormwater conveyance system. The design will include utility coordination, permitting, and alternatives analysis that could include a combination of upsizing the existing system, rerouting flow, runoff reduction, and alternative construction methods to minimize impacts to the Saint Charles Historic District, Main Street, and Frontier Park.
Perry Street from 3rd Street to 2nd Street; 2nd Street between Perry Street and McDonough Street; Water Street from 2nd Street to the outfall(s) at Blanchette Park
