Aside from the aforementioned Kountze Place, Kountze dealt in a great deal of land throughout North Omaha. He sold an tract of land four miles (6 km) north of Omaha and 1½ miles south of Florence to the U.S. Army in 1868. It became Fort Omaha. In the late 19th century he donated land to the Sacred Heart Church at 2206 Binney Street. Kountze donated land to Brownell Hall to relocate from the former town of Saratoga to South Tenth and Worthington Streets in the late 19th century.
