Under the Agreement for Miscellaneous Professional Services for Stormwater Management Improvement Projects the City of St. Petersburg has authorized Land & Water Engineering Science to proceed with the Basin C Resiliency Salt Creek Conveyance Improvements.
LWES is preparing the final design documents and providing support services for permitting of improvements related to roadway flooding along East Harbor Drive, 23rd Avenue South, 7th Street South between 25th Avenue S and 26th Avenue S, 6th Street South and E Harbor Drive, which are caused mainly by channel capacity and downstream hydraulic gradeline. Flooding in this area is exacerbated during the heavier storm events and standing water is present for longer duration during intense rainfall conditions. The proposed improvements will focus on addressing the conveyance capacity of the channel between 22nd Ave S and 7th St S. Channel widening will have a social impact on the neighborhood and environmental conditions. This segment of the channel currently has natural banks consisting of mangroves that are well established. Assessment will also be conducted to investigate sediment conditions, dredging needs, disposal requirements. The project will require mitigation efforts, which may include on-site and banking measures. The proposed improvements will also be evaluated for Sea Level Rise to ensure its resiliency for climate change conditions, and to meet Florida Department of Environmental Protection (FDEP) funding requirements, under the Resilient Florida Grants program.
