Memorandum
DATE: January 19, 2021
TO: City Council
FROM: Mark Ray, PE, Director of Public Works
SUBJECT: Central Core Storm Water Project Update
Background
In April 2020 we last updated the Council on the Central Core storm water study and projects. At this time the
Council also authorized an agreement to start the storm water modeling and project concept designs. In the larger
context of storm water management in the City, over the past few years we have been primarily focused on the
northern portion of Crystal due to the street reconstruction projects, Becker Park resconstruction, and the
underground infiltration system on W. Broadway.
Project update
The storm water modeling work has been completed
with the more recent rainfall data. Based on this
modeling, the potential impacts of a large scale (100
year) rain event are more extensive than what is
currently mapped as a FEMA Flood area.
Project communication
With the modeling complete, preliminary design was
started for both the Gaulke and Brownwood projects.
Within the last month the 50% plans have been
prepared. For Brownwood pond, a copy of these plans
were mailed to all the adjacent property owners so
they could provide input or ask questions. Staff has
requested the resident feedback by the end of January
so that comments or concerns can be addressed as the
design continues. The letter that was sent to residents was included in a Council reading packet.
Project coordination
In addition to the design work occurring, staff have also been working with New Hope, Robbinsdale, Brooklyn
Center, as well as Shingle Creek Watershed Management Commission staff, to conduct a study of stormwater
flow across the four Cities. The goals of this effort are to reduce the risk of one cities’ actions negatively impacting
another, develop pumping operational plans for the two storm water pumps in this larger area, and identifiy
potential locations for future storm water retention.
Recommended action
No formal action is requested at this time. The intent of this item is just a Council update by providing a high-level
overview of what has been completed thus far and the storm water modeling results.
