Title
Informational Presentation from City Engineering Regarding Potential Impacts of the East Isthmus and Yahara Watershed Study Conceptual Solutions on Park Owned Land
Body
Since 2018 City Engineering has been completing watershed studies across 22 study areas citywide to identify areas at risk of stormwater flooding and develop recommendations to reduce those risks. The East Isthmus Watershed Study is currently in progress covering areas in the City of Madison on the Isthmus and nearby, generally east of the Capital Square, South of Aberg Ave, and west of North St and west of Starkweather Creek. The findings and recommendations from this study will be discussed in this presentation.
Watershed studies propose conceptual level improvements that show the scale and type of project necessary to meet flood mitigation targets. City Engineering has identified potential conceptual flood reduction improvements in the East Isthmus Watershed that would result in replacement of storm sewer pipes within multiple Parks within the study area. These recommendations generally include the replacement of existing pipes with larger pipes in the same locations. The locations of these include multiple pipes crossing Demetral Park, a relief storm sewer/upsized outfall through BB Clarke Beach Park, as well as upsized storm sewer outfalls crossing Yahara Place Park, Hudson Park, and several within the Yahara Parkway.
This presentation is intended to inform the Board of Park Commissioners of the proposed improvements and get initial feedback on the acceptability of concepts. City Engineering plans to bring the final watershed study report showing changes to the proposed concepts that impact Parks property after the final phase of public input on the study and a draft final report has been completed. Future detailed construction plans would come back to BPC when the project is budgeted and has undergone detailed design.
