Subject: DeCola Ponds Drainage Study Update
Barr Engineering has completed a first run of the hydraulics and hydrology model for the
DeCola Ponds Drainage Study. This included several “solutions” to analyze the extent
of improvements that may be needed to address the flooding issues for homes
surrounding the ponds and on Medicine Lake Road east of Winnetka Avenue. The
improvements ranged from providing additional ponding to store runoff and reduce
flooding, to bypassing portions of the watershed away from DeCola Ponds.
Golden Valley staff met with staff from the Cities of Crystal and New Hope to discuss
the preliminary findings. Due to time constraints, a follow up meeting has been
scheduled with the affected cities to further discuss the preliminary study findings.
