<br /> <br /> <br />DRAFT 2040 Comprehensive Plan Update – Local Water Management Plan 20 <br />December 27, 2017 - Project CLL17010 <br />2.5 Groundwater Resources <br />Various agencies are responsible for groundwater management and protection. The Minnesota Department of Natural Resources (MnDNR) regulates groundwater usage rate and volume as part of its charge to conserve and use the <br />waters of the State. The Minnesota Department of Health (MDH) is the official State agency responsible for addressing all environmental health matters, including groundwater protection, the well abandonment program, and <br />regulation of the installation of new wells. The Minnesota Pollution Control Agency (MPCA) administers and enforces laws relating to the pollution of groundwater. The Minnesota Geological Survey provides a complete account of <br />the State’s groundwater resources. The RCWD serves as an advisory and educational role in cooperating and assisting the DNR, MDH, and the MPCA in their groundwater protection efforts. <br />Groundwater is at or near the surface in most of Lino Lakes (Appendix A, Figure 9). Groundwater flow generally follows the surface topography and flows towards the Rice Creek Chain of Lakes (Berg 2016) and ultimately <br />towards the Mississippi River (Palen 1993). Groundwater has been known to seep out of natural artesian wells in the Chain of Lakes, especially near the capped St. Paul Water Authority wells in Centerville Lake. The Metropolitan <br />Council has reviewed the surface water and groundwater interactions for Lino Lakes, (Appendix A, Figure 10) which supports these observations and documents the aquifer recharge areas within Lino Lakes. <br />Groundwater studies which include the City of Lino Lakes were completed, or were in the process of being completed during the time this plan was written. Those studies include the following: <br /> Lino Lakes Wellhead Protection Plan <br /> North & East Metro Groundwater Management Area Plan <br /> Anoka County Geologic Atlas, Part B <br /> Anoka Sand Plain Regional Hydrogeologic Assessment <br /> Minnesota DNR Draft Groundwater Management Plan <br />The City of Lino Lakes currently operates six active water supply wells, which draw from groundwater from the Prairie du Chien and Jordan aquifers (Table 2-0-19). Locations of the wells are identified in Appendix A, Figure 9, all <br />six wells are located in a highly sensitive aquifer area, and the vulnerability of the City’s wells and groundwater source varies. Areas closer to Wells No. 1, 3, 4, and 5 contains a lack of low permeability material above the Prairie du <br />Chien and Jordan buried sand, while areas closer to Well No. 2 are considered less vulnerable due to the low permeability of the surficial soils. There are 750 private, non-municipal wells, in the City which are a source of concern for <br />potential contamination within the City’s Drinking Water Supply Management Area (DWSMA). Unmaintained, damaged, poorly constructed, or unused/abandoned wells could provide a direct route for contaminants to enter the <br />aquifers utilized by the City of Lino Lakes as the principal drinking water supply. <br />Table 2-0-19.

These include crop irrigation, sod farms, athletic fields, nursery, and institutional uses of groundwater and surface water. <br />2.6 Existing Conditions <br />Land Uses and Utilities <br />Most of the land in Lino Lakes is classified as rural residential (24%), agricultural (24%) or recreation (18%) and shown on the existing land use map (Appendix A, Figure 11). The land uses are defined below: <br /> Private Airfield: Aviation related uses <br /> Parks and Open Space: Passive or active recreational areas and facilities as well as lands under public control that area designated as permanently undeveloped for the purpose or resource management or protection <br /> Commercial: Retail, office, and service uses <br /> Industrial: Manufacturing, processing, warehousing, and research and development uses <br /> Mixed Use: Mix of residential, retail, and office uses either within one building, structure or development. Residential development may include higher density housing options.
