Bono Consulting has prepared engineering drawings for numerous residential subdivisions, ranging from two lot subdivisions to eighty lot subdivisions. These projects all require storm water detention design, water main permitting from the IEPA, sanitary main permitting from the IEPA and the local sanitary district, roadway design, tree protection, erosion control and site grading. Most subdivision ordinances require implementation of Best Management Practices (BMPs) into the design. BMPs include rain gardens, vegetated swales, grit separators, constructed wetlands, infiltration trenches and buffer strips. We have completed engineering for subdivisions in Burr Ridge, Chicago, Deerfield, DesPlaines, Glenview, Glencoe, Highland Park, Lincolnwood, Mount Prospect, Northbrook, Park Ridge, Skokie, Wilmette, Willow Springs, and Winthrop Harbor. Each community has their own requirements that may exceed the county requirements.
