Commercial buildings in and around Pine Island

An 1895 opera house block and a main street shaped by farm trade

The Bank of Pine Island, Opera House Block at 222 South Main Street was built in 1895 by Loomis F. Irish. Its inventory form calls it an outstanding example of the type of commercial and recreational facilities that appeared in the booming towns of southeastern Minnesota by the end of the 19th century. The first floor held the private bank and the upper floors housed the opera house.

The brick building is three stories tall across its front bays, with a pressed-metal front in the Italianate Commercial Style and a bracketed cornice. The form lists its 1978 use as offices and apartments. Pressed-metal fronts, brick walls and later alterations are all places where age, water and past repairs meet.

The city's 2010 comprehensive plan says the importance of agriculture is reflected in many of the commercial buildings erected on Main Street: banks, hotels, feed stores, farm implement dealers, wagon and carriage shops, general stores and hardware stores. A 1967 survey cited in the plan counted 15 apartments above downtown stores.

Cheese plants, a butter factory and the industrial parks

Pine Island's city site says that in 1911 a group of small dairies built a world-record 6,000 pound cheese on a railroad flatcar, and that by 1920 there were 43 cheese plants in the surrounding area. Half of them formed the Minnesota Cheese Producers Association with a large plant in Pine Island. That plant and its adjoining butter factory were located across from Trailhead Park.

The 2010 plan adds that the Minnesota Cheese Producers Association factory, established in 1920, was sold to Land O'Lakes in 1971. It also says Pine Island had no area dedicated to industrial or commercial use until the late 1980s, with industrial uses mixed in with housing.

The city's first industrial park followed, and in 1995 the city's Economic Development Authority saw the need for more industrial land; a seven-acre industrial and commercial park was then developed, and the plan says all its lots have been sold to new businesses. Food-processing and industrial buildings that have been added to and re-used over many decades usually carry long alteration histories. In structures near a river, roof, drainage and utility history deserve the most attention.

The Zumbro and the buildings near Trailhead Park

The 2010 plan describes the Zumbro River as normally a shallow, muddy stream that is subject to flash flooding after heavy rainstorms, running through a deep narrow valley.

NOAA's flood-impact notes for the North Branch Middle Fork Zumbro River at Pine Island Main Street are specific about buildings. At 10.5 feet, buildings just west of Trailhead Park begin to experience flooding. At 12.5 feet, the intersection of Main Street and East Center Street begins to flood along with nearby businesses.

At 13 feet, there is extensive flooding of buildings along West Center Street and East Center Street between 2nd Avenue NW and Trailhead Park. The notes put the September 2010 record flood at an estimated 13.5 feet.

Trailhead Park appears both in the city's account of the old cheese plant and butter factory, which it places across from the park, and in the NOAA notes that locate flooded buildings. For a buyer, high-water history, basement conditions and where equipment sits are practical questions.
