How will the trail installation affect drainage on the adjacent properties?

In order to minimize disturbance outside of the limits of the trail corridor, the trail profile is proposing to maintain the existing ground elevations to the maximum extent possible while meeting ADA compliant design criteria. With this approach, the project will maintain existing drainage patterns and watershed boundaries to the maximum extent practical. The paving of the trail will increase the impervious surface; however, the project will provide positive drainage throughout the trail system and provide various drainage improvements as needed to ensure there is no increased runoff. Some examples of potential drainage solutions would be bioretention swales, ditches, water quality basins, and other drainage features that comply with Stormwater Low Impact Development and/or Best Management Practices. 

In summary, stormwater will flow in similar patterns and directions as it does today. Engineered water quality features will be installed to offset the increased stormwater blocked by the trails new pavement areas for a net-neutral impact to the area’s stormwater patterns. 

If you have stormwater damage or existing flooding issues, please contact the City to discuss options for your specific property.
