In 2018, Cary implemented an adaptive stormwater management process to monitor and mitigate stormwater and flood impacts in the Walnut Creek basin. This approach relies on citizen engagement and sensor and modeling data to help prioritize capital projects and target infrastructure maintenance needs. It is now being implemented in the Swift Creek basin, where it has facilitated partnerships with developers to mitigate existing issues downstream.
Cary brought forth the basin modeling data and reimbursed the engineer and the developer for the additional design fees and construction costs in the Northwoods Jordan mixed-use and First Baptist Church parking lot projects. Using the partnership strategy, the time and cost for Cary to complete an eventual project was significantly reduced, and structural flooding issues downstream will be resolved simultaneously with the redevelopment project.
In addition, staff launched the maintenance program in the Swift Creek basin, starting in the downtown area. Maintenance work includes inspecting the storm drainpipes in the right-of-way and, where necessary, cleaning the lines. Data derived from the work further enhances Cary’s ability to plan future improvements and maintenance.
