Interstate 24 and Briley Parkway; to the north by Interstate 40; to the east by J. Percy Priest Lake; and to the southeast by the Davidson County line. The subarea includes older suburban subdivisions, new development, large employers and rural lands. Subarea 14 – Donelson – Hermitage This subarea is located on the eastern side of Davidson County and is bounded by the Cumberland River to the west and north; Sumner and Wilson Counties to the northeast and east; Percy Priest Lake, Couchville Pike, Nashville International Airport, and I-40 to the south; and Spence Lane and the CSX railroad to the west. Most of the subarea has gently rolling terrain with steeply sloping land limited mostly to corridors along waterways. Major water bodies in this subarea include the Cumberland River, J. Percy Priest Lake, Stone’s River, Stoner’s Creek, and Mill Creek. Almost half of the land currently developed is residential. Commercial concentrations are in the Donelson and Hermitage areas. There is a major mixed entertainment/commercial concentration in Pennington Bend that includes the Opryland Hotel, the Grand Ole Opry House, and Opry Mills Shopping Mall. An estimated one-fourth of the subarea’s land is currently vacant, a significant portion of which is affected by flooding. POPULATION Since its settlement in 1779, Nashville has grown to become Tennessee’s largest city. Together, Nashville and Davidson County contain a population of 626,144, according to the US Census Bureau. Year Table 2-2. Population Growth Total Population Population Growth 1970 to 2010 Population Change Percent Change 1970 448,003 --- --- 1980 477,811 29808 6.7 1990 510,784 32973 6.9 2000 569,889 59092 11.6 2008 626,144 56268 9.9 (Source: Metro Planning Department and US Census Bureau) Because a large portion of the population of the area surrounding Nashville is dependent on Nashville as a place to work or live, Nashville is the center of the Nashville Metropolitan Statistical Area (MSA). The Nashville MSA comprises thirteen counties including Principal County Davidson, Cannon, Cheatham, Dickson, Hickman, Macon, Robertson, Rutherford, Smith, Sumner, Trousdale, Williamson and Wilson. The MSA population is over one point five million persons. Metropolitan Nashville-Davidson County Community Profile Multi-Hazard Mitigation Plan - FINAL Page 2-8 April 2010
ECONOMIC DEVELOPMENT Nashville is the capital of Tennessee and a vital transportation, business, and tourism center for North America. In addition to the thirteen counties included in the Nashville MSA, the Nashville Economic Market contains two additional counties (Maury and Montgomery). The Region's economy is diverse and mirrors the national economy. The area benefits from low unemployment, consistent job growth, substantial outside investment and expansion, and a growing labor force. Nashville is known as “Music City USA” because of its vast musical heritage and evergrowing musical industry. It serves as the headquarters for more than a dozen major record labels and over 70 smaller labels, approximately 200 recording studios, 130 music publishing companies, 200 booking agents, 10 record manufacturers, and 33 record promotion companies. Although music is the City’s most popular industry, it’s not the largest. Nashville is a leader in the areas of publishing and printing, finance and insurance, healthcare, higher education, and tourism. All of these industries have helped to build and guarantee a strong local economy. Major companies with headquarters or plants in metropolitan Nashville include auto manufacturers Saturn and Nissan; computer manufacturer Dell; national health care providers HCA; restaurants Cracker Barrel and Shoney's; Gaylord Entertainment, owner of Opryland USA and The Nashville Network (TNN). Other key enterprises include Aladdin, a leader in the manufacturing of vacuum bottles and lunch kits; Thomas Nelson, Inc., the world's largest bible publisher; Baptist Sunday School Board and United Methodist Publishing, two of the largest religious publishing houses in the world; and Bridgestone Firestone, Inc, tire manufacturer. Boasting a multitude of world-class companies, Nashville has become a destination for a young, progressive generation of families. Over the past decade, Nashville has seen th tremendous increases in several areas including: population growth in the region to 39 in the United States. The median household income of the county is estimated at $44,486 in 2007. Metropolitan Nashville-Davidson County Community Profile Multi-Hazard Mitigation Plan - FINAL Page 2-9 April 2010
