Chapter 2: Description of Planning Area

2020 Facilities Plan Facilities Plan Report Chapter 2: Description of Planning Area 2.1 Introduction This chapter describes Milwaukee Metropolitan Sewerage District s (MMSD) planning area and existing approved sanitary sewer service area (SSSA) as of March 2005. This chapter also describes relevant watershed planning units and governmental units as well as provides baseline information on population and land use. Although the U.S. Environmental Protection Agency s (USEPA) watershed approach is being used and the greater Milwaukee watersheds (GMW) and the Fox River watershed extend beyond MMSD s planning area, this chapter focuses on the civil divisions, demographics and land use characteristics of MMSD s planning area. During the development of the 2020 Facilities Plan (2020 FP), information was compiled from a variety of sources. Data on the MMSD planning area were compiled from the Southeastern Wisconsin Regional Planning Commission (SEWRPC) 2000 Land Use Inventory.(1) The Technical Memorandum titled Planning Area Boundary Definitions was used as a data source for presenting information on MMSD s planning area. Information on the Regional Water Quality Management (RWQMPU) study area was obtained from Chapter II of SEWRPC Planning Report No. 50, A Regional Water Quality Management Plan Update for the Greater Milwaukee Watersheds. During the development of the 2020 FP, the Technical Advisory Team (TAT) advised MMSD technical staff on technical matters and reviewed technical issues involved with the 2020 FP. Section 1.7 in Chapter 1, Introduction of this report contains details of the nature and extent of the public involvement that was incorporated into the development of the 2020 FP. 2.2 Relationship between the 2020 Facilities Plan and Regional Water Quality Management Plan Update The 2020 FP is integrated with SEWRPC s Regional Water Quality Management Plan Update (RWQMPU). The two agencies worked in concert to develop their respective plans. While the two plans have common goals and integrated public involvement, planning and engineering efforts, they have a different focus; the 2020 FP focuses on MMSD s planning area while the RWQMPU focuses on SEWRPC s study area. Taken together, the MMSD 2020 FP and the RWQMPU are referred to as the Water Quality Initiative (WQI) for the region. In addition to MMSD and SEWRPC, the WQI also involves the Wisconsin Department of Natural Resources (WDNR). These agencies are working together to identify and consider all types water pollution through a long-range planning effort to improve water quality in southeastern Wisconsin. Section 2.6 discusses this in more detail. The Federal Water Pollution Control Act, as amended in 1977, is known as the Clean Water Act (CWA). The following sections outline the main differences between the CWA s requirements for Section 201 planning and Section 208 planning. 2-1

2020 Facilities Plan Facilities Plan Report 2.3 Section 201 Plan Section 201 of the CWA authorizes the administration of grants for the construction of publiclyowned waste treatment facilities. Section 201 mandates the development and implementation of waste treatment management plans using the best practicable waste treatment technology to achieve the goals of the CWA Act. The 2020 FP was prepared pursuant to the requirements of Section 201 of the CWA for the MMSD planning area. 2.4 Section 208 Plan Section 208 of the CWA requires the development and implementation of area wide waste treatment management plans. Section 208 planning seeks to identify and control all sources of point and nonpoint source pollution (NPS) within a geographic area. Section 208 plans facilitate the administration of grants for publicly-owned treatment facilities under Section 201. Proposed waste treatment facilities are required to conform to the area wide Section 208 plan. The RWQMPU provides recommendations for the control of water pollution from point sources, nonpoint sources, and is consistent with the requirements of Section 208 of the Federal CWA. 2.5 Watershed Planning Watershed-based planning occurs over geographic areas that are defined by watersheds as opposed to geographic areas that are defined by civil divisions or governmental units. Management of water quality on a watershed basis integrates planning, public involvement, and the implementation of state-of-the-art solutions and water quality monitoring programs. Chapter 1, Introduction of this report highlights the benefits of watershed-based planning. 2.6 Water Quality Initiative The WQI is a long-range planning process that follows the watershed approach to water quality management. With respect to this collective planning effort, the watershed approach identified and considered all sources of water pollution to the rivers and lakes of the GMWs. The MMSD worked with SEWRPC on the planning effort because the GMWs extend beyond the MMSD planning area. The 2020 FP is fully integrated with RWQMPU. In fact, the two planning efforts shared technical analysis and data and SEWRPC managed the water quality modeling for both studies. 2.7 2020 Facilities Planning Area and Regional Water Quality Management Plan Update Study Area The USEPA s watershed approach to water resource management uses the watershed as the planning unit to define the areas to coordinate the management of water resources by addressing all activities within a landscape or watershed that impact water quality.(2) The planning units employed by the RWQMPU consist of whole watersheds. As a result, SEWRPC s study area covers approximately 1,127 square miles in nine counties in southeastern Wisconsin. The RWQMPU study area is further discussed in Section 2.9. 2-2

2020 Facilities Plan Facilities Plan Report The 2020 FP focuses on MMSD s planning area, which encompasses approximately 411 square miles. The MMSD planning area primarily consists of a subset of RWQMPU study area. Outside of the GMW, approximately 42 square miles of the MMSD planning area that is located in the Fox River watershed, which is not included in the RWQMPU study area. The 2020 FP is integrated into RWQMPU to realize the full potential of watershed-based planning. The combination of the two areas addressed by the parallel planning efforts is referred to as the 2020 FP/RWQMPU study area. 2.8 Milwaukee Metropolitan Sewerage District Planning Area As part of the 2020 facilities planning process, the 2020 technical team defined the MMSD planning area in a technical memorandum titled Boundary Definitions Technical Memo, dated April 16, 2003 and revised September 29, 2003 and November 17, 2003.(3) The community boundaries as of that date included all municipalities in Milwaukee County (except South Milwaukee) and all or part of nine municipalities in surrounding counties are included in the MMSD planning area. These municipalities include the following: Brookfield, Muskego, and New Berlin in Waukesha County; Butler, Elm Grove, and Menomonee Falls in Waukesha County; Mequon and Thiensville in Ozaukee County; and Germantown in Washington County. The MMSD planning boundary extends south of Milwaukee County into Racine County, as MMSD provides sanitary sewer service to the Caddy Vista Sanitary District in Caledonia. The MMSD planning area is shown in Figure 2-1. 2.9 Regional Water Quality Management Plan Update Study Area As noted in Section 2.7, the planning units of the RWQMPU are whole watersheds. A watershed is a term used to describe the geographic area of land that drains water to a shared destination. The drainage system (and the watershed) also includes the geographic area surrounding the stream system that captures precipitation, filters and stores water, and determines water release into stream systems. The stream system is the visible, aboveground portion of a larger drainage system. A watershed, therefore, is "an area of land that drains water, sediment, and dissolved materials to a common outlet."(4) The RWQMPU study area generally follows the natural boundaries of the GMW, as displayed in Figure 2-2. Each of the GMWs drains to one of the following main receiving waters: Kinnickinnic River Lake Michigan direct tributary drainage Menomonee River Milwaukee River Oak Creek Root River 2-3

2020 Facilities Plan Facilities Plan Report 2.10 Boundary Definitions The following terms are used throughout the 2020 FP to differentiate overlapping study boundaries and jurisdictions in the greater Milwaukee area. 1) SEWRPC Planning Area. The SEWRPC is the official planning agency for southeastern Wisconsin and serves the following seven Wisconsin counties: Washington, Ozaukee, Waukesha, Milwaukee, Walworth, Racine and Kenosha. SEWRPC was established in 1960. Five of the seven counties are served or partially served by MMSD. SEWRPC provides planning for land use, public works systems (e.g., highways and water supply) and environmental issues (e.g., flooding and water pollution). 2) MMSD Planning Area. The MMSD planning area is shown in Figure 2-1. It is primarily contained within the 2020 FP/RWQMPU study area. The following assumptions apply to MMSD s planning area: Northern Boundary - The portion of the Milwaukee River watershed that lies within Ozaukee County is not included in MMSD s planning area. This area will be studied for the RWQMPU. Southern Boundary The portion of the Root River watershed located south of Milwaukee County will be studied in the RWQMPU. This area is not included in MMSD s planning area. Western Boundary - The western MMSD planning area boundary generally follows the subcontinental divide. However, approximately 42 square miles of MMSD s planning area along the western boundary lay outside of the GMW. These areas will be evaluated for sanitary conveyance only. Eastern Boundary - The eastern planning area boundary is located along the Lake Michigan shoreline, extending from Pioneer Road on the north to approximately 3 Mile Road on the south. 3) MMSD Existing Approved Sanitary Sewer Service Area. The existing approved SSSA, as of January 1, 2007, is shown in Figure 2-1, and is recommended by SEWRPC and WDNR through a joint planning program that was approved by MMSD. Communities are required to follow an established amendment process if they wish to modify their SSSA. The process is facilitated by SEWRPC and involves the community, SEWRPC, WDNR, MMSD, and the public. Changes to MMSD s SSSA are recommended by SEWRPC and the WDNR and approved by MMSD s Commission. The boundary may change over time based on requests initiated by a municipality, SEWRPC, or WDNR. The MMSD SSSA as of January 1, 2007 does not include the south half of the Superior Emerald Park Landfill located at W124 S10629 South 124th Street within Muskego; however, this area is included within MMSD s planning area boundary. 4) 2020 FP/RWQMPU Study Area. This is the comprehensive water resource planning area that constitutes the planning area for the WQI. This area includes all or parts of nine counties in southeastern Wisconsin and is defined by the boundaries of the following five 2-6

2020 Facilities Plan Facilities Plan Report watersheds: Milwaukee River, Menomonee River, Kinnickinnic River, Oak Creek, and Root River. The 2020 FP/RWQMPU study area also includes the estuary, as well as the Lake Michigan direct tributary drainage area, shoreline, and near-shore area. 2.11 Description of Planning Units Consistent with the watershed approach, watersheds are used as the planning units for the RWQMPU. A watershed planning unit is a geographical area that is defined as the land area where all surface drainage flows to a common watercourse, and can be used to manage water quality through local, state and regional initiatives designed to complement each other. Throughout the watershed, decisions that impact water quality are based on all the watershed s water resources, water uses, and all threats to water quality. The use of watersheds as planning units is advantageous because it allows officials to consider all activities throughout a watershed that impact water quality rather than just the activities from a specific governmental unit. The MMSD planning area includes approximately 36% of the entire GMW and 4.5% of the Fox River watershed. The planning units within the MMSD planning area are limited to portions of the Menomonee, Milwaukee, Fox and Root River watersheds, and consist of the Kinnickinnic River and Oak Creek watersheds in their entirety. The Lake Michigan direct tributary drainage area is the land mass located in the MMSD planning area that drains directly to Lake Michigan. This is only a small portion of the vast Lake Michigan watershed. In the MMSD planning area, the portion of the Lake Michigan direct tributary drainage area that is included in the water quality modeling effort is located south of Fox Point. While the pollutant loading from the portion of the drainage area located north of Fox Point is not being modeled, this land mass is a part of the MMSD planning area. Demographic and land use data are presented for the entire Lake Michigan direct tributary drainage area within the MMSD planning area. The following sections describe the demographics, land uses and civil divisions associated with the planning units in the MMSD planning area. The data is presented by watershed, and only includes data from the portions of the watersheds that fall within the MMSD planning area. Chapter 2 of SEWRPC Planning Report No. 50, A Regional Water Quality Management Plan Update for the Greater Milwaukee Watersheds contains a description of the demographics, land uses and civil divisions associated with the whole-watershed planning units that comprise the 1,127-square mile GMW. This report also includes discussions of public utilities, transportation facilities, and natural resources and environmental features of the watershed planning units that comprise the GMW. 2.12 Civil Divisions and Watershed Area within the Milwaukee Metropolitan Sewerage District Planning Area The MMSD planning area includes and bisects a number of civil divisions. Civil divisions, or governmental units, form the basic foundation of the public decision-making framework. Table 2-1 presents the municipalities that are both located within the GMW watersheds and located within the MMSD planning area. The area of a watershed that is contained within a municipality is presented in square miles and as a percentage of the watershed that is located within the MMSD planning area. 2-7

2020 Facilities Plan Facilities Plan Report The portion of the Menomonee River watershed that falls within the MMSD planning area is approximately 130 square miles and contains 14 civil divisions. This area comprises the largest planning unit and contains the greatest number of civil divisions within the MMSD planning area. The portions of the Milwaukee River and Root River watersheds that are located in the MMSD planning area consist of 95 square miles and 71 square miles, respectively. The Fox River planning unit comprises 42 square miles, and the Lake Michigan direct tributary drainage area is approximately 21 square miles. The Fox River planning unit contains five civil divisions. The Lake Michigan direct tributary drainage area, along with the Milwaukee and Root River watersheds, each contain 10 to 11 civil divisions within the MMSD planning area. While the MMSD planning area consists of the Oak Creek and Kinnickinnic River watersheds in their entirety, these watersheds are the smallest planning units in the MMSD planning area. They range in size from 22 to 25 square miles and contain five and six civil divisions, respectively. 2.13 Demography How land is used and how intensely it is used generally determines the extent of the demand on natural resources in a watershed. Specifically, direct relationships exist between population levels, land use, and the demand for land, water, and other natural resources. For example, the need for expanded sanitary sewer service grows with an expanding population. If the conveyance and treatment systems are not designed to handle the increased flows, there is a greater potential for surface water impacts from sanitary sewer overflows. In 2000, the MMSD planning area that is located within the GMW had a total population of 1,066,978 persons and contained 425,227 households.(5) Table 2-2 presents 2000 data on population and households for the MMSD planning area by municipality. The Milwaukee River and Menomonee River watersheds have the highest populations with 34.0% and 30.4%, respectively. Portions of these two watersheds comprise the largest planning units within the MMSD planning area. The population density in the Milwaukee and Menomonee River watersheds is approximately 3,800 and 2,450 people per square mile, respectively. These are mid-range population densities relative to densities calculated for other planning units in the MMSD planning area. The Kinnickinnic River watershed has 13.5% and the Root River watershed has 10.1% of the population in the planning area. The lowest populations are located within the Lake Michigan direct tributary drainage area, the Fox River watershed, and the Oak Creek watershed. Approximately 12% of the population of the planning area resides within these areas. The portion of the Kinnickinnic River watershed in the MMSD planning area has the greatest population density with approximately 5,850 people per square mile. The lowest population densities are noted in the Fox River, Oak Creek and Root River watersheds, with approximately 750, 1,400, and 1,500 people per square mile, respectively. Chapter 2 of SEWRPC Planning Report No. 50, A Regional Water Quality Management Plan Update for the Greater Milwaukee Watersheds contains more information on demographics. 2-9

2020 Facilities Plan Facilities Plan Report 2.14 Land Use The type, intensity, and spatial distribution of land uses within a watershed largely determine the resource demands within that watershed. Changes in land use are important considerations for the management of water quality. As populations grow and as development expands, the amount of impervious land surface generally increases. Increased imperviousness typically increases greater runoff during rainfall events and a greater potential for nonpoint source pollution impacts to area watercourses. Tables 2-3, 2-4, and 2-5 present the types of land use within the MMSD planning area. As indicated in Table 2-3, about 121.9 square miles (29.7%) of this area are in residential use, ranging from high density residential to rural residential. Table 2-4 shows that 39.7 square miles (10%) are in commercial, industrial, institutional / governmental, communications, and utility use. Table 2-5 shows that the balance of the land use, approximately 251 square miles (61%) is open space, freeways, transportation (without freeways), recreation, agriculture, and landfills. Land use types not only affect the loads of NPS delivered to area waterways, they also directly impact which best management practices (BMP) can be installed or implemented to minimize or reduce NPS. For instance, contributions of NPS from high-density residential and highlydeveloped areas can be minimized by using BMPs that are designed to function in urban environments or that require little space. On the other hand, NPS from agricultural and rural land uses can be addressed with BMPs that are specially designed for these types of land uses.
