Recent past studies that WSB has completed <br />will be used to inform this section. <br /> <br />Information about wetlands will be obtained through the existing wetland delineation <br />information and readily available desktop data, such as the National Wetland Inventory. <br /> <br />For the stormwater analysis, WSB will prepare a planning level stormwater analysis for the <br />scenarios. This will include general analysis of before and after conditions as well <br />as requirements for stormwater management based on MPCA, City, and Watershed <br />District requirements. <br /> <br />For groundwater, existing soils mapping and groundwater information from the USGS will be <br />used to analyze impacts to susceptible groundwater features in relation to proposed land use. <br /> <br />WSB will analyze the proposed water use and wastewater generation based on the three <br />development scenarios and the recent studies that WSB has completed. This will be reviewed in <br />relation to the municipal system’s ability to serve the area. <br /> <br />Task 6 – Review of Contamination / Hazardous Wastes <br />Available studies and information will be used to complete this section of the Update. If the <br />scenarios include the potential for hazardous wastes to be stored or generated within the project <br />area, that will be included in this section as well. <br /> <br />Task 7 – Review of Fish and Wildlife <br />Information from past site visits and the DNR Natural Heritage Database will be used to describe <br />and evaluate wildlife impacts to the area. From the existing information and the field review, the <br />impact of the development scenarios on these resources will be summarized in the Update. <br /> <br />Task 8 – Review of Historic Properties, Visual Impacts, and Parks <br />Information from the City, State Historical Preservation Office, and the readily available public <br />data will be used to determine if there are impacts to historic properties or parks or if there will be <br />visual impacts. Based on our understanding of the site and proposed development, we do not <br />expect there will be visual impacts per the AUAR guidelines. This information will be used to <br />complete the AUAR Update. <br /> <br />Task 9 – Traffic Analysis <br />The traffic mitigation measures will be reviewed and updated if needed, based on changes in land <br />use from the 2040 Comprehensive Plan, other studies completed in the area, and the <br />implementation of roadway improvements. The updated traffic study will include: <br /> <br />Data Collection: Updated traffic data will be collected from MnDOT, Washington County <br />and the City of Lino Lakes. It is assumed that no additional traffic counts will be collected. <br /> <br />Traffic Generation: Area traffic generation will be updated and compared to the traffic <br />generation from the previous AUAR updates. <br /> <br />Traffic Forecasts: The traffic forecasts will be updated to 2040 based on the current <br />land use plans and anticipated development scenarios <br />
