<br /> Anoka County 2019 <br />Multi-Jurisdictional <br />All Hazards Mitigation Plan <br /> <br /> 139 <br />dominate the landscape in Columbus, covering nearly two-thirds of the City. While Columbus is <br />a large community (48 sections approx. 30,573 acres) the amount of developable land in the <br />City is much less than surrounding communities. Approximately, 9,300 gross acres and 5,660 <br />net acres of land are used as rural residential, which requires a 5-acre minimum lot size. <br /> <br />Public lands: The public/institutional land use category includes the Columbus City Hall, Fire <br />Hall, and Public Works complex on Kettle River Blvd. and Notre Dame Street; public utilities; <br />four churches; the Columbus Elementary School; State “school trust” land; and two Wildlife <br />Management Areas. The gross public/institutional acreage is approximately 11,175 acres or <br />over 36% of the total City acreage. The only City site that is on the National Register of Historic <br />Places is the Carlos Avery Game Farm, located at County Highways 17 and 18. It has been on <br />the Register since 1991. It is the site of buildings built by the WPA in the 1930’s and includes <br />an entrance gate to the site that is built of stone and iron. During that era, it was a national <br />showplace for the rearing of quail. The facilities are now the home of the north metro wildlife <br />office of the Department of Natural Resources (DNR), the headquarters for the DNR’s Carlos <br />Avery Wildlife Management Area, and the Wildlife Science Center, a nonprofit group that <br />conducts research on wolves. <br /> <br />There are approximately 654 acres of City and County park land in Columbus, which provide <br />active and passive recreation opportunities to residents and businesses. The City currently has <br />one community park, three neighborhood parks and three undeveloped, natural areas. The City <br />maintains the major community park adjacent to the City Hall that includes land on either side of <br />Kettle River Boulevard. This facility includes five softball diamonds, two tennis courts, a <br />volleyball court, a football field, a picnic area and shelter, and playground equipment. Anoka <br />County owns and maintains Coon Lake County Park, which includes a swimming beach, boat <br />access, and picnic facilities. <br /> <br />Private fee areas: There are few fee areas in Columbus. <br /> <br />Ag riculture and forestry: Columbus has 2 Century Farms. The Furrer Farm and the <br />Thurnbeck Farm. The Furrer farm became a Century Farm in August 1989. Alfred Bergeron <br />(1857 – 1949) came to Minnesota as a young man of seventeen in 1874 from Quebec, Canada. <br />He bought his first forty acres on the eastern edge of Anoka County in the City of Columbus <br />between Forest Lake and Centerville in 1883. The Thurnbeck farm was settled in 1893 and <br />became a Century Farm in 1994. <br /> <br />Although Columbus is currently being developed, the minimum lot size is 5 acres, which does <br />allow for the preservation of a significant portion of the current tree cover. These forests are <br />comprised mainly of Northern Pin Oak, Burr Oak, Red Oak, and White Oak. Of the mature <br />forest, the oaks comprise roughly 60 – 70 % of the tree species, with minor contributions of <br />hackberry, red maple, basswood, aspen, white pine, red pine and spruce. The most significant <br />forestry problem currently is oak wilt disease. The community has participated in an extensive <br />oak wilt management program since 1991 to contain the effects of this devastating disease. <br /> <br />For the future, tree preservation of its existing woodlots and invasive pests will be the largest <br />threats to this suburban forest. <br /> <br />Commercial and industrial development and trends: There are two primary commercial <br />areas within Columbus, which account for 6% of the total City area. One lies along the <br />southerly portions of Lake Drive (CSAH 23) near Lino Lakes. The other surrounds a portion of
