DISCUSSION
AGENDA ITEM: Flooding Discussion
SUBMITTED BY: Kristina Handt, City Administrator
BACKGROUND:
A number of properties experienced flooding issues this spring/summer due to the high ground water
levels. The city council last discussed flooding issues at their February work session. Since that time the
city has provided sand and bags to Lake Elmo property owners, assisted Valley Branch Watershed
District (VBWD) in the pumping of two ponds-Legion Ave and Reid Park, provided information to
Cimarron management about flooding, and attended a tour hosted by the county in July of flooded areas
in Lake Elmo. At the tour it was mentioned the county and watershed district would be having a work
session to discuss next steps. We have invited the county and watershed to this work session to provide an
update to the council.
ISSUE BEFORE COUNCIL:
Receive update from Washington County and Valley Branch Watershed District and provide feedback as
appropriate.
PROPOSAL DETAILS/ANALYSIS:
Per the watershed district, the typical flood management options are usually grouped into 1) reduce the
runoff coming into the basin (e.g., divert, hold back, etc.) to lower the flood level, 2) create an outlet to
lower the flood level, and/or 3) remove or structurally protect the problem structures from the floodplain
(e.g., raise, fill basements, berm, remove, etc.).
The VBWD began the process to amend their plan in September to allow for the purchase of flooded
property on Klawitter Pond and Freidrich’s Pond in Lake Elmo. These were both visited during the tour in
July.
The VBWD is also preparing a work plan to submit with an application to the U.S. Army Corps of Engineers
to study the feasibility of creating permanent outlets from several landlocked basins, most within the City
of Lake Elmo. The work plan is not expected to be completed until the end of this year. The study will
involve stakeholders, including the city of Lake Elmo and Washington County, and will likely take at least
a year to complete. If VBWD orders a construction project, another Plan amendment would be needed.
Funding for the study and pumping of areas in Lake Elmo is included in the draft 2021 VBWD budget.
