Spotlight: Oak Creek Streambank Stabilization


In 2022, Senior Environmental Engineer Jack Sudar completed a project stabilizing a stretch of the Oak Creek. See his write up of the project below, as well as the full 2022 Wisconsin Report on Soil and Water Conservation at the following link.

Bank Stabilization at Dineen Park

Bank Stabilization at Dineen Park

Milwaukee County owns and maintains over 70 ponds and lagoons. In response to concerns over water quality in these water bodies, Environmental Services developed the Milwaukee County Pond and Lagoon Management Plan to assess the environmental quality of the lagoons and recommend improvements. The effort included several pilot projects focusing on bank stabilization and native plant installations on several ponds.

Solar Panels at Juneau Park

Environmental Services piloted several solar-powered projects including the County’s first photovoltaic installation at the Juneau Park comfort station. Other solar-powered facilities by the Environmental Services at Washington and Wilson Park Senior Centers paved the way for other installations within the County.

Land Conservation

We also serve as the Land Conservation Department. Our primary functions are to develop and implement the Milwaukee County Land and Water Resource Management Plan and administer grants to landowners to help reduce soil erosion, manage nutrients, and minimize pollution of surface and groundwater.

Land and Water Resource Management Plan

Land and water resource plans are developed to identify, prioritize and address land- and water-related resource conservation issues in the County. Plan goals include:

  1. Improve water quality through the reduction of sediment and nutrient delivery to surface waters in Milwaukee County
  2. Protect, maintain and restore land and water resources in Milwaukee County
  3. Enhance Lake Michigan bluff protection initiatives
  4. Maintain the existing information network and land information web portal
  5. Limit the introduction and reduce the spread of invasive species in Milwaukee County

Sanitary Sewer CMOM Program

What Is CMOM?

The general purpose of Milwaukee County's Capacity, Management, Operation and Maintenance (CMOM) program is to assist in reducing sanitary sewer overflows.

How the CMOM Program Came About

When combined sewer overflows and sanitary sewer overflows occur, they present important concerns for public health and the environment. The Milwaukee Metropolitan Sewerage District (MMSD) has been working to reduce the amount of overflows that occur for decades. In 2002, MMSD was required to implement an ongoing CMOM program as a part of a stipulation agreement with the State of Wisconsin’s Department of Natural Resources. Part of MMSD’s CMOM plan is to open and maintain dialog with the 29 satellite municipalities in developing their own individual CMOM programs. Milwaukee County is one of those municipalities that are required to maintain a CMOM program.

Milwaukee County’s Sanitary Sewer System

Milwaukee County is unique in that, unlike other municipalities, its sewers are spread out throughout the entire County. Milwaukee County has sanitary sewers in the following locations: County Parks, Airports, Milwaukee County Transit System (MCTS) facilities, County Grounds, Milwaukee County Zoo, and the County Correctional Facility South. In total, Milwaukee County has approximately 1,000 sanitary sewer manholes and 225,000 linear feet of sanitary sewer.

Milwaukee County’s CMOM Program

Milwaukee County started its CMOM program in 2007. It consists of a written plan directed at reducing sanitary sewer overflows through stated goals and objectives, and it also lists the strategies and tactics that will be employed to achieve the goals. An important part of the CMOM is the Overflow Response Plan, which lists the correct actions to take if a sanitary sewer overflow or SSO occurs.
