The CURA publications library is currently being digitized by the University of Minnesota Digital Conservancy. When the project is complete, the entire CURA publications library will be online and fully searchable. Unfortunately, during this process we are not able to honor individual requests for publications . Additionally, we no longer have physical copies of publications to send out.

New publications are digitized daily and the publications catalog on the CURA website is not automatically updated with links to scanned copies, so please search the CURA collection at the Digital Conservancy for the publications you are looking for:

Ridgedale Mall Stormwater Management.

Author: 
Titus, Jordan, Chao Sun, Jacon Guzik, Jessica Tello, Sarah Hazelwood, and Christina Caoutte.

Produced by students in CE 5511: Urban Hydrology and Land Development (Instructor John Gulliver, Civil Engineering) as part of the 2013-2013 Resilient Communities Project partnership with the City of Minnetonka.

An expansion on the Ridgedale Mall has created a need for a new storm water management system. A previous landscape architecture study was analyzed to consider what options might be feasible for this site . It was determined that pervious pavement, rain gardens, tree trenches, rainwater harvesting and green roofs were feasible optionsfor reducing and treating runoff from the Ridgedale Mall site.

Infiltration is the most cost effective way to treat storm water i f feasible. To determine if the site was suitable to implement infiltration, research on the depth of the water table and the soil composition was studied. The water table is greater than 6.5 feet away from the surface for 68.9% of the site area. The main soil types are B and C soils. Both of these parameters were determined to be suitable for infiltration.

A working model in HydroCAD was created in order to determine dimensions needed in order to fulfill storm water standards using these design options. Based on areas that had both a relatively low water table and suitable soils, optimal placements of infiltration options were determined. This model was then analyzed based on cost in order to determine the cost effective options for the site. Based on the Removal Efficiency Analysis, rain gardens and tree trenches are the most cost effective options. Green Roofs were very expensive to implement and not necessary in order to handle the water.
