The Southeast Heights Neighborhood Association, or SEHNA, encompasses the historic neighborhoods of Hyder Park, Carlisle, and Ridgecrest. The area is characterized by numerous parks, tree-lined boulevards, and gracious, older homes in open, park-like yards. Many homes were built in the 1920s and 1930s. Close to downtown, uptown, the University, Nob Hill, and the airport, our friendly neighborhoods are great places to live. We hope you will join SEHNA and work with us for the betterment of our beautiful and historic area.
