<br /> <br /> <br />DRAFT 2040 Comprehensive Plan Update – Local Water Management Plan 26 <br />December 27, 2017 - Project CLL17010 <br />1-2 cfs. As a result, the City of Lino Lakes is contemplating a new conveyance system and outlet structure to Peltier Lake from the 1,400-acre development area, which would be subject to review and approval by the RCWD. This <br />may require the development of alternative standards (stormwater rules) to demonstrate no adverse impacts through use of RCWD Comprehensive Stormwater Management Plan (CSMP) provisions. <br />Water Quality Issues <br />Current data indicate that water bodies located within the City have water quality issues. Several City lakes, such as Bald Eagle, Peltier, George Watch, Marshan and Centerville, Reshanau, Baldwin and Rice Lakes are included in the <br />MPCA’s impaired waters list. In addition, both Clearwater and Hardwood Creeks are also included on the 303(d) TMDL list due to biotic impairments. A TMDL was recently completed for the Upper Mississippi River to address the <br />water quality standard for E. coli. <br />Runoff carrying nutrient-rich sediment, road salts, and hydrocarbon-based contaminants is detrimental to the water quality of the City’s lakes, streams, rivers, and wetlands. Current water quality conditions present a potential stress to <br />the diversity and population of fish and aquatic invertebrates and impact human uses of the resources. Improvement of these waters will require a watershed wide solution because in many cases much of the drainage area originates <br />upstream of the City. Additionally, it has been found that internal loading sources of phosphorus derived from the lake bed sediments in Peltier Lake are affecting the water quality of downstream water bodies. <br />Wetland Management Issues <br />Benefits attributed to wetlands include floodwater storage and retention, nutrient assimilation, sediment entrapment, ground water recharge, low flow augmentation, shoreland anchoring and erosion control, aesthetics, recreation, and <br />education. Accordingly, the loss of wetland acres, function and value will have a direct negative effect on the City and its water resources. <br />Floodplain Management Issues <br />Given the physical characteristics, high water table, and number of water bodies and flood prone areas, floodplain management is an important consideration to minimize future flooding events. In addition, a number of areas of <br />current flooding concern have been identified by the City Public Works Department and RCWD. Future flooding could also be a concern if development is not conducted in a manner that reduces runoff rates and volumes and if <br />changes in rainfall and snowmelt patterns overwhelm existing infrastructure. <br />Public Ditch System Issues <br />Several of the major drainageways in the City are public ditch systems managed by the Rice Creek Watershed District. Some of the public drainage systems are located within completely urbanized areas, have been totally or partially <br />replaced by storm sewer pipe, and no longer serve agricultural land or provide agricultural benefits. These systems function as the outlet for storm water runoff. Other public drainage systems are comprised nearly entirely of <br />undeveloped/agricultural areas that are primarily forecasted for urban development. Public ditch systems need to be managed to provide the drainage services suited to the land contributing to the system. <br />Groundwater Management Issues <br />The City of Lino Lakes relies solely on groundwater as its water supply source. The Prairie du Chien- Jordan aquifer serves as the City’s municipal water source. There is a growing concern that water supplies may be depleting. This <br />will affect not only the drinking water supplies, but also resources that may depend on groundwater, such as wetlands, lakes and streams. The DNR established the Northeast Metro Groundwater Management District in 2012 to <br />regionally manage the area’s aquifers. <br />Natural Resources Issues <br />Lino Lakes is rich in unique and rare natural resources. These resources are most often hydrologically dependent on natural water systems. Reduced quality and variances of water levels stemming from land use changes may have <br />critical impacts to the sustainability of these resources. Preserving and enhancing quality natural resources within the City can have a positive effect on surface and ground water. Extensive development or misuse of the natural areas <br />within the City can have deleterious effects on water resources. <br />Erosion and Sediment Control Issues <br />Erosion prevention and sediment control is an important aspect in the effort to improve water quality and protect and improve water and natural resources. Erosion is caused by runoff over disturbed soils such as on a construction <br />site or along streambanks. This erosion can result in the transport of sediment into water and natural resources. Sediment deposits and sediment transport can decrease water quality and increase maintenance efforts. <br />Regulations, Permitting and Reporting Issues <br />The City is regulated under a number of local, state, and/or federal programs that require the implementation of ordinances, permitting, and/or reporting. In addition, the City implements ordinances and permitting to attain the goals <br />outlined in this Plan.
