WETLANDS Wetlands within the study area have been identified using the National Wetland Inventory (NWI). There are approximately 156.4 acres of freshwater emergent, freshwater forested/shrub, and freshwater pond wetlands within the study area, as well as 17.5 acres of riverine features. Additionally, high priority wetlands are noted on the figure below and establish critical nodes and linkages for what will become the Wetland Management Corridors. High priority wetlands were identified based on the function of the wetland habitat, characteristic wetland hydrology and water quality, wetland role in downstream flooding, as well as plant species and community diversity. It is anticipated that wetlands within the study area boundary will be subject to regulation under the Wetland Conservation Act (WCA) and/or the US Army Corps of Engineers (USACE). DITCHES The ditches mapped throughout the study area are generally located between agricultural fields or adjacent to existing roadways and congregate in the southeastern portion of the study area before flowing offsite to the south. The public ditches located onsite are part of the Anoka County Ditch (ACD) system 10-22-32, denoted as the Public Drainage System maintained by Rice Creek Watershed District. All three ditches are mapped within NWI and Lino Lakes High Priority Wetlands in the study area. NATURAL RESOURCES AND DRAINAGE EXISTING ROADWAY NETWORK The study area is bound by Pine Street NE to the north, Sunset Avenue (CSAH 53) to the west, Century Trail and Carl Street to the south, and 4th Avenue to the east. Main Street (CSAH 14) is an east-west road that bisects the study area. The area currently has limited road access in the area north of Main Street and several east-west streets on the south side including Lilac Street, Robinson Drive, Carl Street and Century Trail. TRANSPORTATION FLOODPLAIN Floodplains within the study area have been identified using the FEMA’s National Flood Hazard Layer Viewer. A significant portion of the site (~40-45% by area) is covered in FEMA Zone A. Additionally, FEMA Flood Zone AE is mapped offsite to the south and east. Rice Creek Watershed District has also delineated the area as localized 100-year floodplain. Permitting requirements from FEMA, city and Rice Creek Watershed District must be met for future development in the study area within floodplain areas. Refer to the Lino Lakes Main Street AUAR for more detail of the site and context. Site Features MAPPING NORTHWEST MAIN - MAIN STREET MASTER PLAN AUGUST 25, 2025 BACKGROUND | 11Page 65 of 171
