Milwaukee County Grounds Park does not yet have a formal address.  The Milwaukee County Parks system lists the address for County Grounds Park identical to the county headquarters:  9480 Watertown Plank Road.  The county headquarters and the park are within 2 blocks of each other and the address is functional for general navigation. 


Sometimes County Grounds Park is commonly referred to as "Sanctuary Woods" - which is a geographic subset of County Grounds Park. 


Milwaukee County Grounds Park in Wauwatosa has limited parking which is accessible from either:

  • 87th Street north of Watertown Plank Road

    • Google/Waze/Apple-map-point "Sanctuary Woods Parking"

    • See map and navigation guidance on this website's homepage

  • Discovery Parkway south of Swan Boulevard

Reporting Suspicious Activity:

Unfortunately, the Milwaukee County Grounds have come under increased abuse during the COVID-19 crisis. Perhaps increased boredom is leading to more extreme behavior.  Perhaps perpetrators believe there is less use and oversight.  

The Milwaukee County Grounds is patrolled and enforced by the Milwaukee County Sheriff's Department.  Please be part of the solution and report any suspicious activity.  This can be done 2 ways:

1.) Urgent reports are most efficiently reported directly to the sheriff at:  414-278-4788 
2.) Non-urgent reports, tips, chats can be engaged through the Milwaukee County Sheriff app.  Here is a link to the iphone app:

Thanks for helping take clear ownership for our shared space.

We are always seeking park history to include in our interactive maps, new ideas that support our mission, volunteers who support the activities, and more friends to support planning/organization.  We can be reached at
