March 2023 update
On December 12, 2022, City of St. Louis Park staff presented a written status report to city council titled ‘MnDOT excess land update – Toledo Avenue and 28th Avenue – ward 1’.
Recommended action: None. This is a status report to city council.
Policy consideration: Does city council want staff to pursue acquisition of the land that Minnesota Department of Transportation (MnDOT) has deemed to be excess right-of-way?
Summary: MnDOT officially offered to convey to the city two parcels of land they deem to be excess right-of-way along Highway 100 in the 2800 block of Toledo Avenue South. We received these offers in response to the letter of interest we sent to MnDOT in February 2022. We have until May 22, 2023, to accept the offers and purchase the parcel(s). The city council previously received staff reports regarding this matter on November 22, 2021, and February 7, 2022.
Restore Lilac Way hopes they do the right thing and bring both parcels into the SLP Park System for public enjoyment.
A growing community campaign encourages the city to take ownership of this Depression-era Lilac Way park for public use. As a sister park to Lilac Park, it deserves to be saved.
MnDOT divided Rock Island Park into two separate land parcels.

The Council must make a decision about each of two parcels.
The south parcel has the 1939 Depression-era rock garden and surrounding green space. (MnDOT will transfer this land to the City at no fee, only if it is kept as park land.)
The north parcel has the meadow, home to wild turkeys, deer, insects and birds. (MnDOT is finalizing a final value/price for this parcel; if SLP chooses to buy it, they could use it as public land, or for development.)
Council must decide between public or private use.
If the City DOES WANT TO REQUEST OWNERSHIP of Rock Island Park at not cost for public use, they would need to send a letter to MnDOT requesting the land.
If the City DOES NOT WANT TO REQUEST OWNERSHIP of Rock Island Park at not cost for public use, MnDOT will sell the land to a private developer and this historic 1930 Lilac Way park would most likely be destroyed for development.
That would be a tragedy.
What’s next?
St. Louis Park’s city council will review a final staff report, discuss and schedule a vote.
A final report will be attached to the council memo when they are asked to make a decision.
All of the emails from residents and Rock Island Park supporters will be submitted to Deb Heiser and will be attached to the council memo when they are asked to make a decision.
Restore Lilac Way is hoping to also include images from the “Say Yes to Rock Island Park” virtual rally.

A November 2022 staff report was the first step in bringing Rock Island Park ownership to council.
A 11-page report provided the council with background on the land and identifies four potential land uses. Three of those four options includes private development. Only one includes public use.
The Nov. 22nd study session did not include a formal discussion or any decision-making. The purpose was to see if the council would like more information prior to having a discussion on the topic.

One of only three remaining Lilac Way parks.
One of only two rock gardens left in Minnesota.
A sister park to restored Lilac Park.
Rock Island is all that remains of the old Lilac Park on Minnetonka Boulevard and Highway 100 in St. Louis Park. It was built in the 1930s as a Works Progress Administration (WPA) project to provide employment during the Great Depression.
It has an oval pool, a 10′ footbridge to an island and handcrafted curved stone bench with stone pathways. Locals often called it Monkey Island. Map.
The rare beehive fireplace from the south end of old Lilac Park was saved from demolition and restored in a new Lilac Park.

This park is native habitat for plants and creatures, including insects, birds, deer, and wild turkeys.
Visit, you’ll be glad you did. It’s like going back in time.
It’s on Google maps. This treasured historic 1930s park is safely hidden behind a sound wall in the NE corner of Highway 100 and Minnetonka Boulevard in St. Louis Park, Minnesota.
You can’t see Rock Island from the street, it is lower than street level.
Walk towards the clump of trees near sound wall. You will see a mowed path, and come up to a small stairway that leads you down into the rock garden.
Why was Rock Island nicknamed ‘Monkey Island’?
Lilac Park’s north end is called Rock Island. The Rock Garden’s pond, island, footbridge, bench and pathways are all that remains of the old park.
In the 1930s, the WPA built seven parks along Lilac Way, as well as ‘Monkey Island’ at the Como Park Zoo. Rock Island’s nickname comes from Como Park’s ‘Monkey Island,’ which was renamed ‘Seal Island’ in the 1980s.

Rock Island’s key dates
- In 1968 the original Lilac Park was split in two by a highway on-ramp, and Lilac Park activities were reduced
- the park could no longer be accessed from the highway
- the grade from Toledo Ave. was steep and difficult to walk down
- the rock garden that was north of the beehive fireplace and picnic area was cut off from the rest of the park
- In 2008, the 1939 beehive fireplace and picnic tables were saved, and moved to a restored Lilac Way park on Highways 100 and 7, which was renamed Lilac Park
- In July 2009, a crew mistakenly cut down all the trees that hid this park, making it visible to traffic on Highway 100
- In 2017, Rock Island was again hidden, when a new sound wall was installed along Highway 100
