Title
Informational Presentation from City Engineering Regarding Potential Impact of a Warner Park and Cherokee Marsh Watershed Study Conceptual Solutions on Park Owned Land
Body
Watershed Studies have been completed, are in progress or will be completed by City Engineering for the City’s 22 watersheds over the next 5 years. The Warner Park and Cherokee Marsh Watershed Study is in progress and is discussed in this presentation.
City Engineering has identified potential flood reduction improvements in the Warner Park Watershed on the east side of Warner Park in the Castle Creek Channel and Warner Park Parking Lot near N Sherman Ave. The improvements would include a new relief sewer along the south side of the parking lot, lowering and widening the existing Castle Creek channel alignment along Trailsway, and removal of the existing concrete cunette section of Castle Creek. The improvements are outside of active mowed park space. A flood mitigation project on Castle Creek could also serve as an opportunity to make improvements to the corridor recommended within the Warner Lagoon Water Quality Plan, finalized in 2021 in conjunction with a variety of stakeholders, including the Parks Division and approved by the Board of Parks Commission in Legistar File #64906. This presentation is designed 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. Watershed studies propose conceptual level improvements that show the scale and type of project necessary to meet flood mitigation targets. Future detailed plans would come back to BPC when the project is budgeted and has undergone detailed design.
