The Tattersall Storm Drainage Improvement Project will reduce street and structure flooding throughout the neighborhood and address stream erosion to provide a more natural, stable stream system. Located within a drainage area of approximately 130 acres, the project will replace and/or rehabilitate aging infrastructure and provide adequate drainage system capacity. 

Estimated Cost: $7,000,000*

*includes all costs associated with this project such as planning and design, utility relocation, consultant fees, permits, construction, and landscaping.
