4.0Impact of Changes to the Public Water Supply Wells In accordance with the requirements of Minnesota Rules 4720.5220, anticipated changes in the physical environment, land use, surface water, and groundwater in the DWSMAs within the next ten years and the impact of these changes on the source water aquifers are discussed in this section. 4.1Potential Changes Identified 4.1.1Physical Environment As shown on Figure 2, approximately 31% of the area in the DWSMAs is currently undeveloped. By 2030, the Metropolitan Council projects that all the land within the DWSMAs will be developed (see Figure 3). As discussed elsewhere in this Plan, the Metropolitan Council preliminary estimate of the 2018 population of Ramsey is 27,051. The (Ramsey, 2018a) projects tha water supply system will serve 13,921 people in 2020 and 22,987 in 2030. The draft Water Supply Plan experience significant growth by 2030. Changes in land use resulting from the projected growth are not anticipated to result in land uses different than found elsewhere in the DWSMAs and would not be expected to significantly affect the source water aquifer. Therefore, potential changes to the physical environment will likely not affect the management strategies for the Ramsey DWSMAs presented in this WHPP amendment. (Ramsey, 2018a) anticipates that additional pumping capacity will need to be added to the water supply system in 2023, based on current growth projections. In addition, the being added to the system in 2028. It is anticipated that new wells would be installed in the Tunnel City- Wonewoc aquifer. The installation and operation of one or more new wells would require an assessment of whether the boundaries of the DWSMAs would need to be modified. This will be done when the City is directed to do so by the MDH and may require the assistance of the Wellhead Protection Consultant. The West DWSMA is contained entirely within the Ramsey city limits. The East DWSMA extends into a portion of the city of Anoka. Locations of the RamseyDWSMAs are shown on Figure 1. 4.1.2Land Use As indicated in the Ramsey (Metropolitan Council, 2015), general geographic planning designation is Emerging Suburban. Current land uses in the Ramsey DWSMAs that cover more than one percent of the area in the DWSMAs include Residential of various types, Undeveloped land, Park/Recreational/Preserve, Retail and Other Commercial, Agricultural, Major Highways, and Open Water. Projected future land uses within the City are anticipated to include many of the land uses currently present within the DWSMAs. 10 10
