In 1886, the Welch Addition doubled the size of the Berthoud as town boundaries extended south beyond present-day Mountain Avenue for the first time. A year later a hose company was hastily formed to protect the town from fire after the Davis & Hartford Mercantile store burned to the ground. In 1888 a town board was elected and within a short time they hired a marshal to keep the peace and light the street lamps. By the early 1900s, Berthoud sported a business district on Third Street and Massachusetts and Mountain Avenues.
