2 <br /> <br />ANALYSIS <br /> <br />Background <br /> <br />Per the applicant’s narrative, Laborer’s Training Center offers construction industry <br />vocational training. They have been at this location since 1993 and have outgrown their <br />current working/training bays, classrooms, and storage space. <br /> <br />The proposed project will include a new building with working/training bays, classrooms, <br />offices, and an auditorium. The expansion will also include additional parking, an access <br />road, utilities, and stormwater ponds. <br /> <br />General Site Characteristics <br /> <br />The existing site is approximately 18 acres. The current training facility is approximately <br />40,000 square feet with an outdoor training facility to the east and a parking lot with 163 <br />spaces to the west. The southern half of the site is generally composed of wetlands and <br />wooded open space that will not be impacted by the site expansion. <br /> <br />The proposed addition will include a building covering 37,284 square feet and an <br />additional 167 parking spots. <br /> <br />Soils <br /> <br />Per the Geotechnical Exploration Report, four soil borings encountered 0.5-1.0 foot of <br />topsoil comprised of sandy lean clay. Beneath the topsoil was sandy lean clay glacial till <br />that extended to the termination of the borings at 14.5 feet. <br /> <br />Infiltration was not deemed possible for this site due to the low permeability of the soils <br />and the high water table indicated by the surface elevation of the wetlands. <br /> <br />Stormwater Management, Erosion and Sediment Control <br /> <br />Stormwater management plan has been submitted and is being reviewed by the City <br />Engineer. <br /> <br />The following general review is adapted from the May, 2020 Stormwater Management <br />Plan prepared by Barr Engineering Co. <br /> <br />All impervious surfaces for the site will be routed through two proposed stormwater <br />ponds, which will be constructed south of the existing and proposed buildings and north <br />of existing wetlands. The outlet structure for both ponds will connect to existing 12” <br />storm sewer pipes, which outlet into wetlands to the south. <br /> <br />Ultimately, water discharges through wetlands to the south, then to Clearwater Creek, <br />and finally to Peltier Lake.
